技术领域technical field

本发明是有关于一种锁固件设计，特别是指一种具快速旋锁的锁固件。The invention relates to a design of a locking piece, in particular to a locking piece with a quick twist lock.

背景技术Background technique

参阅图1、图2，现有的一种平头螺丝1包含有一杆体11，一螺旋设于该杆体11表面上的螺牙12，一与该杆体11一端连接的螺头13，以及一于该杆体11上且相反于该螺头13另一端的锁合部14；其中，该螺头13具有一顶面131，一连接该顶面131与该杆体11且由该顶面131朝向该杆体11呈渐缩延伸的连接面132，以及多数等角度相同间隔地凹陷形成于该连接面132上的切刃133，而前述该每一切刃133皆具有两相隔地自该顶面朝向该杆体11方向弯弧延伸且呈弧状的切刃面134；是以锁合于对象2时，该螺牙12切削后所产生的毛边将随着该螺牙12旋入方向转动，并沿着成弯弧状的该等切刃133与该等切刃面134转动时的导引作用，顺势将该毛边压入该对象2中，同时该等切刃133与该等切刃面134还可以把该对象2经该螺牙12挤压的膨胀凸起部份压平，以使该对象2表面更加平整，以有效避免毛边、膨胀凸起与裂材等缺陷情事产生。Referring to Fig. 1, Fig. 2, existing a kind offlat head screw 1 comprises ashank 11, athread 12 that is screwed on the surface of theshank 11, ascrew head 13 connected with one end of theshank 11, and a screw on theshank 11. On therod body 11 and opposite to thelocking portion 14 at the other end of thescrew head 13; wherein, thescrew head 13 has atop surface 131, which connects thetop surface 131 and therod body 11 and faces therod body 11 from thetop surface 131 The connectingsurface 132 that is tapered and extended, and a plurality ofcutting edges 133 that are recessed and formed on the connectingsurface 132 at equal angles and at the same intervals, and each of theaforementioned cutting edges 133 has two intervals from the top surface toward the direction of therod body 11 The arc-shapedcutting edge surface 134 is extended and arc-shaped; so when it is locked on the object 2, the burr generated after thethread 12 is cut will rotate with the screw-in direction of thethread 12, and along the arc-shaped The guiding effect of thecutting edges 133 and thecutting edge surfaces 134 when they rotate, presses the burr into the object 2, and simultaneously thecutting edges 133 and thecutting edge surfaces 134 can also push the object 2 through The part of the expansion protrusion squeezed by thethread 12 is flattened to make the surface of the object 2 more smooth, so as to effectively avoid defects such as burrs, expansion protrusions and cracks.

但是，实际使用后发现，该现有技术中的凹陷处的设计仅可供切屑容置，再加上该等切刃133与该螺牙12旋入方向呈相同的设计，以便该等切刃133得以于旋入过程中达到压掣旋锁毛边、及对象2的膨胀现象；但是，实际使用测试后发现，该结构设计模式仍有改善的空间，故方有本案的设计产生。However, after actual use, it is found that the design of the recess in the prior art can only accommodate chips, and thecutting edges 133 are designed in the same direction as thescrew thread 12, so that thecutting edges 133 can achieve the depressing twist lock burr and the expansion of the object 2 during the screwing process; however, after the actual use test, it is found that there is still room for improvement in this structural design mode, so the design of this case came into being.

具体实施方式Detailed ways

为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

参阅图3至图5，本发明的一较佳实例，包含有一杆体31，一设于该杆体31一端的螺头32，一设于该杆体31上且相反于该螺头31一端的锁合部33，以及多个螺旋环设于该杆体31上的螺牙34；其中，该锁合部34在本实施例中可为钻尾及尖尾等态样的设置，而以下说明以尖尾构造为之。Referring to Fig. 3 to Fig. 5, a preferred example of the present invention includes arod body 31, ascrew head 32 arranged at one end of therod body 31, and a locking lock at the end of therod body 31 opposite to thescrew head 31.part 33, and a plurality ofscrew threads 34 with spiral rings arranged on therod body 31; wherein, thelocking part 34 can be set in the form of a drill tail and a pointed tail in this embodiment, and the following description uses a pointed tail constructed for it.

仍续上述，该螺头32具有一顶面321，一由该顶面321向下延伸的底面322，多个设于该底面322上的辅助块323，以及该任两相邻的辅助块323间形成有一容置区324；其中，该每一辅助块323具有一位于该容置区324的一侧并由该底面322向上延伸形成的一壁面3231，一由该壁面3231朝另一相邻的该容置区324的另一侧相接形成的顶掣壁3232，以及一于该顶掣壁3232与该壁面3231相接形成的切刃3233，且该顶掣壁3232由该顶面321朝该杆体31方向呈渐缩态样，以便该顶掣壁3232上形成有一由该切刃3233延伸向该相邻的容置区324的另一侧的辅助壁3234，且该辅助壁3234与该顶掣壁3232相接处呈一倾斜设置，而前述该顶掣壁3232在本实施例中呈一弧面设计表示；另，该容置区324鉴于该等辅助块323的结构设计因素，使得该等容置区324容置空间得以扩大。Still above, thescrew head 32 has atop surface 321, abottom surface 322 extending downward from thetop surface 321, a plurality ofauxiliary blocks 323 arranged on thebottom surface 322, and any two adjacentauxiliary blocks 323 Anaccommodating area 324 is formed between them; wherein, eachauxiliary block 323 has awall surface 3231 located on one side of theaccommodating area 324 and extending upward from thebottom surface 322, and awall surface 3231 extending from thewall surface 3231 to the other adjacent The other side of theaccommodating area 324 is connected to thetop wall 3232 formed, and acutting edge 3233 is formed on thetop wall 3232 and thewall 3231, and thetop wall 3232 is formed by thetop surface 321 It is tapered towards therod body 31, so that anauxiliary wall 3234 extending from thecutting edge 3233 to the other side of the adjacentaccommodating area 324 is formed on thetop stop wall 3232, and theauxiliary wall 3234 and theauxiliary wall 3234 The junction of thetop stop wall 3232 is inclined, and the above-mentionedtop stop wall 3232 is shown as an arc design in this embodiment; in addition, theaccommodating area 324 considers the structural design factors of theauxiliary blocks 323, The accommodating space of theaccommodating areas 324 is enlarged.

参阅图3、图4，锁合时，先于该螺头32施予一锁合扭力以连动该锁合部33钻锁进入锁合物4内，同时带动该螺牙34对该锁合物4产生锋利的切削，以使该锁固件3得以快速锁合进入该锁合物4内，且当该螺头32进入时，可借该等辅助块323的切刃3233辅助切削，亦即于切削过程且断裂的该锁合物4的木纤维受到该切刃3233切削，以确实被斩断，有效避免该木纤维缠绕产生阻力的缺失，同时锁合时产生的切屑可受到该顶掣壁3232朝向该杆体31渐缩态样的设计，使该切屑可顺沿该顶掣壁3232至辅助壁3234向外排出，借以大幅减少该锁固件3锁合的扭力，同时再借该容置区324的容置空间的扩大设置，不但可供过多该切屑容置于其中外，同时该锁固件3锁合于该锁合物4后，更能与该锁合物4产生紧密锁合效果，以避免该切屑无法完全容置所产生的裂材情况，且更借由该辅助壁3234与该顶掣壁3432相接处呈一倾斜的配合设置，使凸伸于外的该切屑于锁合时得以受到该辅助壁3234的压掣，进而顺势在锁合时被压掣于该锁合物4内，以避免该切屑过多凸伸于外，有效维持锁合后的该锁合物4的平整度，使该锁固件3锁合后得以与该锁合物4相互产生紧密卡掣锁合效果，大幅提升锁合后的紧固力等功效。Referring to Fig. 3 and Fig. 4, when locking, first apply a locking torque to thescrew head 32 to drive thelocking part 33 to drill and lock into the lock 4, and at the same time drive thethread 34 to lock the lock The object 4 produces a sharp cutting, so that thelocking member 3 can be quickly locked into the locking object 4, and when thescrew head 32 enters, thecutting edge 3233 of theauxiliary blocks 323 can be used to assist cutting, that is The wood fiber of the lock 4 that is broken during the cutting process is cut by thecutting edge 3233 to be cut off, effectively avoiding the lack of resistance caused by the entanglement of the wood fiber. The tapering design of thewall 3232 toward therod body 31 allows the chips to be discharged outward along thetop wall 3232 to theauxiliary wall 3234, thereby greatly reducing the locking torque of thelocking member 3, and at the same time, by the accommodating The enlarged setting of the accommodating space in thezone 324 can not only accommodate too many cuttings therein, but at the same time, after thelocking member 3 is locked on the lock 4, it can be tightly locked with the lock 4 effect, so as to avoid the situation that the chips cannot be completely accommodated, and theauxiliary wall 3234 and the top stop wall 3432 are provided with an inclined fit, so that the protruding chips are in the When locking, it can be pressed by theauxiliary wall 3234, and then be pressed into the lock 4 during locking, so as to avoid excessive protruding of the cutting chips and effectively maintain the locked after locking The flatness of the object 4 enables thelocking member 3 to produce a tight locking effect with the locking object 4 after being locked, and greatly improves the fastening force and other effects after locking.

归纳前述，本发明具快速旋锁的锁固件，于该螺头的底面上设有多个辅助块，且该任两辅助块间形成有一容置区，因此当锁合时，不但借由该等辅助块的辅助配合以产生快速切削外，且该容置区亦可供辅以切削后的切屑容置于内，借以与该锁合物产生紧密锁合，且该锁固件锁合后不会有任何切屑凸伸于该锁合物外，以增加锁合后的平整度，以使锁合更能有效大幅提升锁合后的紧固力，故确实能达到本发明的目的。To sum up the foregoing, the present invention has a fast twist lock fastener with a plurality of auxiliary blocks on the bottom surface of the screw head, and an accommodation area is formed between any two auxiliary blocks, so when locking, not only by the In addition to the auxiliary cooperation of auxiliary blocks such as auxiliary blocks to produce fast cutting, the accommodation area can also accommodate the chips after cutting, so as to form a tight lock with the lock, and the lock will not lock after locking. There will be any cutting chips protruding from the lock to increase the smoothness after the lock, so that the lock can be more effective and greatly improve the fastening force after the lock, so the purpose of the present invention can indeed be achieved.

惟以上所述者，仅为说明本发明的较佳实施例而已，当不能以此限定本发明实施的范围，即大凡依本发明申请专利范围及发明说明书内容所作的简单的等效变化与修饰，皆应仍属本发明专利涵盖的范围内。But the above are only preferred embodiments for illustrating the present invention, and should not limit the scope of the present invention with this, that is, all simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the description of the invention , all should still belong to the scope covered by the patent of the present invention.
