A kind of ball studTechnical field
The invention belongs to plant equipment, particularly relate to a kind of ball stud.
Background technology
At present, in plant equipment, bolt makes plant equipment couple together as a kind of securing member usually attaching nut, and bolt is generally made up of bolt head and screw rod, and the effect of bolt head is easy for the dismounting of bolt.Existing bolt head generally becomes quadrangle, hexagon or octagonal etc., but under specific circumstances, the plant equipment being provided with bolt has some given shape, needs bolt to support the use with it, and realizes fastening function.
It is therefore desirable to propose a kind of new bolt to solve the problems referred to above.
Summary of the invention
The invention aims to solve above-mentioned technical problem, it is provided that a kind of ball stud, its reasonable in design, and can realize fastening corollary equipment, bolt mounting process is easy, it is possible to reduces and loosens.
To achieve these goals, the present invention can adopt the following technical scheme that:
A kind of ball stud, it include head and with the integrated screw rod in described head one end, it is characterized in that, it is uniformly provided with at least three projection on the periphery of the described head other end, the center of the described head other end is additionally provided with the limiting section with bulb, and described limiting section includes cylinder that the round platform having the bulb of symmetrical facet, one end is welded to connect with facet described in one, one end be welded to connect with the described round platform other end the most successively and extends, along the described cylinder other end, the arc-shaped head being welded to connect with described head.
As the preferred embodiment of the present invention, ball stud farther includes the facet of described bulb and runs through a through hole.
As the preferred embodiment of the present invention, it is hollow body that ball stud farther includes described round platform.
As the preferred embodiment of the present invention, it is hollow body that ball stud farther includes described cylinder.
As the preferred embodiment of the present invention, ball stud farther includes the diameter of described through hole and fixes the equal diameters of one end of the round platform being connected and the diameter of the other end of the most described round platform with described facet.
As the preferred embodiment of the present invention, ball stud farther includes the diameter of described bulb and the equal diameters of described cylinder and the diameter of the other end being all higher than described round platform.
As the preferred embodiment of the present invention, it is circular that ball stud farther includes described head.
The invention has the beneficial effects as follows: the ball stud of the present invention, compared with prior art, have employed and be provided with three projections and limiting section at the head other end, not only can realize fastening corollary equipment, the setting of limiting section is also convenient for taking, improves work efficiency.The present invention, reasonable in design, mounting process are easy, also can reduce loosening between securing member.

Detailed description of the invention
Describe the present invention below with reference to each embodiment shown in the drawings.But these embodiments are not limiting as the present invention, structure, method or conversion functionally that those of ordinary skill in the art is made according to these embodiments are all contained in protection scope of the present invention.
With reference to shown in Fig. 1, Fig. 2, ball stud, it include head 1 and with the integrated screw rod in described head 1 one end 2, it is uniformly provided with at least three projection 3 on the periphery of described head 1 other end, the center of described head 1 other end is additionally provided with the limiting section with bulb 4, and described limiting section includes cylinder 6 that the round platform 5 having the bulb 4 of symmetrical facet, one end is welded to connect with facet described in one, one end be welded to connect with described round platform 5 the most successively and extends, along described cylinder 6 other end, the arc-shaped head 7 being welded to connect with described head 1.
Wherein, the facet of described bulb 4 runs through a through hole 8, attractive in appearance and be greatly saved cost.
Concrete, described round platform 5 is hollow body, and described cylinder 6 is hollow body, can cost-effective and processing simplicity.
Wherein, the diameter of described through hole 8 fixes the equal diameters of the one end of the round platform 5 being connected and the diameter of the other end of the most described round platform 5 with described facet, the equal diameters of the diameter of described bulb 4 and described cylinder 6 and be all higher than the diameter of the other end of described round platform 5, cost-effective, reasonable in design simultaneously, increases the stable installation between securing member.
Concrete, described head 1 is circular, attractive in appearance, and design is simple, and is greatly saved cost.
It is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should be using description as an entirety, technical scheme in each embodiment can also form, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that.
The a series of detailed description of those listed above is only for illustrating of the feasibility embodiment of the present invention; they also are not used to limit the scope of the invention, and all equivalent implementations or changes made without departing from skill of the present invention spirit should be included within the scope of the present invention.
