Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of locking connectors, and particularly relates to a quick dismounting rotary locking connector capable of self-homing. BACKGROUND

[0002] At present, shaft connectors cannot be conveniently and quickly dismounted. If quick dismounting is required, most of them use magnetic couplers. However, the magnetic force sharply attenuates with the increase of distance, and in a high centrifugal force, vibration or high temperature environment, the magnetic force will weaken or fail. Some use a structure of a magnet plus friction force, which relies on the friction torque generated by the pressing force. When the input or output end is started, braked or the load suddenly changes, the inertial torque may instantaneously exceed the maximum static friction torque, resulting in slipping or falling off. Moreover, the magnetic coupler is complex to install, positioning tools are required, and it cannot be quickly dismounted and installed without tools according to requirements. SUMMARY

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0019] The following disclosure provides many different implementations or examples for carrying out different structures of the embodiments of the present invention. To simplify the disclosure of the embodiments of the present invention, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples of the embodiments of the present invention; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed.

[0020] To better understand the purpose, structure, and function of this invention, the following detailed description of a self-resetting, quick-disassembly rotary locking connector of this invention is provided in conjunction with the accompanying drawings.

[0021] like Figures 1-16 As shown, a self-resetting, quick-disassembly rotary locking connector of the present invention includes a drive input base 1 and an output base 2. During assembly, the drive input base 1 and the output base 2 are aligned and installed along their axes. One side of the drive input base 1 is provided with an input shaft sleeve 15, and the other side is provided with a first boss 16. A second boss 17 is provided at the end of the first boss 16. The input shaft sleeve 15 and the first boss 16 are both located at the center of the drive input base 1. The inlet end sidewall of the input shaft sleeve 15 is provided with an input shaft set screw hole 13. After inserting the input shaft into the input shaft sleeve 15, tightening the screw in the input shaft set screw hole 13 will fix and lock the input shaft. The sidewall of the first boss 16 is provided with four W-shaped structures 12 arranged in a circumferential array, and each pair of adjacent W-shaped structures 12 is connected by an edge protrusion.

[0022] The surface of the drive input base 1 is provided with four first magnet mounting holes 14 arranged in a circumferential array. The surface of the output base 2 is provided with a through hole. The size of the second boss 17 matches the size of the through hole. The inner wall of the through hole is provided with a quick-release protrusion 21. The side wall of the second boss 17 is provided with four quick-release protrusion holes 11 arranged in a circumferential array, and the four quick-release protrusion holes 11 correspond one-to-one with the four quick-release protrusions 21. The size of the quick-release protrusions 21 matches the size of the quick-release protrusion holes 11. The surface of the output base 2 is provided with four second magnet mounting holes 22 arranged in a circumferential array, and the four second magnet mounting holes 22 correspond one-to-one with the four first magnet mounting holes 14.

[0023] When installing, just align the quick release protrusion hole 11 with the quick release protrusion 21, and then install the two structural magnets with their installation surfaces adhering to each other. At this time, the first magnet installation hole 14 and the magnet in the second magnet installation hole 22 attract each other, completing the quick connection and installation of the input and output ends, and the input shaft is assembled by using a set screw through the input shaft set screw hole 13. If quick disassembly is desired, just manually separate the left and right structures.

[0024] When working, the two ends move by the magnetic force of the magnets, and when the torque of the twist is greater than the magnetic force of the magnets, the magnetic force is not enough to support the movement of the output end base 2, and the driving input end base 1 and the output end base 2 will have a relative rotational displacement. The magnets in the first magnet installation hole 14 and the second magnet installation hole 22 cannot provide enough force to maintain movement, and after the relative rotation occurs, the quick release protrusion 21 rotates in the W-shaped structure 12 in the driving input end base 1. After rotating to a certain extent, it is stopped by the edge protrusion of the W-shaped structure 12 as shown in Figure 13 At the same time, the support force generated can further provide force for transmission. At the same time, the quick release protrusion 21 is clamped in the W-shaped structure 12 and cannot move axially, completing the locking function.

[0025] When the input torque of the final input end motor stops, the magnets in the first magnet installation hole 14 and the second magnet installation hole 22 will attract each other. At this time, the magnetic force is greater than the static friction force, and the driving input end base 1 and the output end base 2 rotate, returning to the initial installation state and completing the automatic homing function. At this time, the quick release protrusion hole 11 and the quick release protrusion 21 are in an aligned state, and at this time, the quick release state is achieved.

[0026] It can be understood that the present application is described by some embodiments, and those skilled in the art know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the present application. In addition, under the guidance of the present application, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the present application. Therefore, the present application is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are within the scope of the present application.
