本发明提出一种旋转模组，可应用于摄影件(例如，魔术转接头、快拆板、手柄、三脚架和上手提等)，作为摄影件的旋转关节；安装有该旋转模组的摄影器材，可与另一摄影件通过旋转模组转动相连，将其中一摄影件与摄影设备相连，即可以快速方便对摄影设备进行转动调节和锁定。The present invention proposes a rotary module, which can be applied to photographic pieces (such as magic adapters, quick release plates, handles, tripods, and upper handles, etc.), as the rotary joints of photographic pieces; photographic equipment equipped with the rotary module , can be rotated and connected with another photographic piece through the rotating module, and one of the photographic pieces is connected with the photographic equipment, that is, the rotational adjustment and locking of the photographic equipment can be performed quickly and conveniently.

参照图1至图5，在本实施例中，该旋转模组包括外壳10、转轴20、传动组件(未标号)和两个环形保持架40，其中：1 to 5, in this embodiment, the rotary module includes ahousing 10, ashaft 20, a transmission assembly (not numbered) and twoannular cages 40, wherein:

外壳10设有安装孔(未标号)；Thehousing 10 is provided with mounting holes (not labeled);

两个环形保持架40沿安装孔的轴向依次转动设于安装孔内，两环形保持架40内具有轴向通孔，转轴20穿插于两环形保持架40中，即插在两环形保持架40的轴向通孔中；Twoannular cages 40 are installed in the mounting holes sequentially rotated along the axial direction of the mounting holes. The twoannular cages 40 have axial through holes. 40 in the axial through hole;

两环形保持架40经传动组件传动配合，传动组件用于在一环形保持架40转动时，带动另一环形保持架40向相反方向转动，即两环形保持架40是联动的；The tworing cages 40 are driven and matched by the transmission assembly, and the transmission assembly is used to drive theother ring cage 40 to rotate in the opposite direction when onering cage 40 rotates, that is, the tworing cages 40 are linked;

环形保持架40设有沿其周向分布的多个安装槽41，转轴20在对应两个环形保持架40的外周壁均设有凸起的抵接部21，安装槽41中设有滚动件41，一环形保持架40对应的抵接部21的凸起高度均沿转轴20的第一周向(例如，顺时针方向或逆时针方向)逐渐增大，另一环形保持架40对应的抵接部21的凸起高度均沿转轴20的第一周向逐渐减小，滚动件41设置在抵接部21与安装孔内壁之间。Thering cage 40 is provided with a plurality of mountinggrooves 41 distributed along its circumference, and therotating shaft 20 is provided with protruding abuttingparts 21 on the outer peripheral walls corresponding to the tworing cages 40, and rolling elements are arranged in the mountinggrooves 41. 41. The protrusion height of the abuttingportion 21 corresponding to oneannular cage 40 increases gradually along the first circumferential direction (for example, clockwise or counterclockwise) of therotating shaft 20 , and the corresponding abutting portion of the otherannular cage 40 The protruding heights of the connectingparts 21 decrease gradually along the first circumferential direction of therotating shaft 20 , and the rollingelement 41 is disposed between theabutting part 21 and the inner wall of the installation hole.

本实施例的旋转模组的工作原理为：1、在需要锁定旋转模组时，通过相对外壳10朝第一方向(例如，顺时针方向或逆时针方向)转动一个环形保持架40(为方便理解和后续描述，记为第一环形保持架40)，第一环形保持架40朝第一方向的转动经传动组件带动另一环形保持架40(记为第二环形保持架40)，相对外壳10朝第一方向的反方向(记为第二方向)转动，使两个环形保持架40的滚动件41移动到抵接部21凸起较高的一端与安装孔内壁之间，滚动件41的两侧分别抵紧抵接部21和安装孔内壁，如此，滚动件41与抵接部21之间的摩擦力增大，滚动件41与安装孔内壁之间的摩擦力也增大，使转轴20通过滚动件41与外壳10实现锁定；并且，由于两个环形保持架40对应的抵接部21的凸起高度增大方向相反，因此，当滚动件41抵紧在抵接部21和安装孔内壁之间时，无论是顺时针还是逆转动转轴20或外壳10，都会使其中一个环形保持架40的滚动件41分别与抵接部21和外壳10抵紧的更紧，可以保证锁定状态稳定可靠。2、在需要解锁旋转模组时，通过相对外壳10朝第二方向转动第一环形保持架40，在传动组件的传动作用下，第二环形安装架则相对外壳10朝第一方向转动，使两个环形保持架40的滚动件41从抵接部21凸起较高的一端与安装孔内壁之间，移动至抵接部21凸起较低的一端与安装孔内壁之间，滚动件41不在抵紧抵接部21和安装孔内壁，滚动件41的两侧分别抵紧抵接部21和安装孔内壁，如此，滚动件41与安装孔内壁及抵接部21之间的摩擦力大幅降低，滚动件41可相对外壳10和抵接部21自由转动，实现转轴20与外壳10之间的解锁。The working principle of the rotary module of this embodiment is: 1. When the rotary module needs to be locked, rotate an annular cage 40 in a first direction (for example, clockwise or counterclockwise) relative to the housing 10 (for convenience) Understanding and follow-up description, denoted as the first annular cage 40), the rotation of the first annular cage 40 in the first direction drives another annular cage 40 (denoted as the second annular cage 40) through the transmission assembly, and the opposite shell 10 rotates in the opposite direction of the first direction (referred to as the second direction), so that the rolling elements 41 of the two annular cages 40 move between the higher end of the abutting portion 21 and the inner wall of the mounting hole, and the rolling elements 41 The two sides of the two sides are respectively pressed against the abutting portion 21 and the inner wall of the mounting hole, so that the friction force between the rolling element 41 and the abutting portion 21 increases, and the friction force between the rolling element 41 and the inner wall of the mounting hole also increases, so that the rotating shaft 20 is locked with the housing 10 through the rolling element 41; and, since the protrusion heights of the abutting portions 21 corresponding to the two annular cages 40 increase in opposite directions, when the rolling element 41 is pressed against the abutting portion 21 and installed Between the inner walls of the hole, no matter whether the rotating shaft 20 or the housing 10 is rotated clockwise or reversely, the rolling element 41 of one of the annular cages 40 will be pressed against the abutting portion 21 and the housing 10 more tightly, which can ensure the locked state Stable and reliable. 2. When it is necessary to unlock the rotary module, by rotating the firstannular retainer 40 in the second direction relative to thehousing 10, under the driving action of the transmission assembly, the second annular mounting frame rotates in the first direction relative to thehousing 10, so that The rollingelements 41 of the twoannular cages 40 move from between the higher end of the abuttingportion 21 and the inner wall of the mounting hole to between the lower end of the abuttingportion 21 and the inner wall of the mounting hole, and the rollingelements 41 Instead of pressing against the abuttingportion 21 and the inner wall of the mounting hole, the two sides of the rollingelement 41 respectively abut against the abuttingportion 21 and the inner wall of the mounting hole. In this way, the friction force between the rollingelement 41 and the inner wall of the mounting hole and the abuttingportion 21 is greatly increased. When lowered, the rollingmember 41 can rotate freely relative to thehousing 10 and the abuttingportion 21 , so as to realize the unlocking between therotating shaft 20 and thehousing 10 .

本实施例的旋转模组在摄影件上使用时，外壳10与一个摄影件连接，转轴20则与另一个摄影件连接，这样，两个摄影件就可以通过将旋转模组调至解锁状态时，以转动调节两个摄影件之间的角度，以及通过将旋转模组调至锁定状态，以将两个摄影件锁定在当前角度。When the rotary module of this embodiment is used on a photographic piece, thehousing 10 is connected to one photographic piece, and therotating shaft 20 is connected to another photographic piece. , to adjust the angle between the two photographic pieces by rotating, and adjust the rotation module to the locked state to lock the two photographic pieces at the current angle.
