Description

TECHNICAL FIELD

[0001] The present application relates to a connecting piece, in particular to a multi-joint rotary connecting all-directional adjustable locking device, which is suitable for mechanical structure connection scenes that need to flexibly adjust the angle and position relationship, such as joint connection of medical instruments, multi-directional adjustment components of industrial equipment, etc. BACKGROUND

[0002] In the field of mechanical connection, especially in the application scenarios involving multi-joint rotation, the need for flexible adjustment of angle and stable locking, such as joint parts of medical rehabilitation equipment, posture adjustment mechanisms of industrial automation equipment, etc., there are many defects in the prior art. The traditional joint connection locking device either has insufficient adjustment flexibility, can only realize rotation in a limited direction, and cannot meet the demand for all-directional angle adjustment, or has a complex locking structure, cumbersome operation, and time-consuming and laborious locking and unlocking process, which affects the efficiency of the device.

[0003] Some devices attempt to use multi-joint design, but the locking mechanism at the joint has poor reliability and is prone to looseness and unlocking failure when subjected to external force, which cannot stably maintain the adjusted posture. For example, some joint structures based on simple buckles or bolt connections are prone to wear and tear, resulting in poor clamping, and bolt adjustment is not convenient, making it difficult to quickly achieve precise angle locking and switching. At the same time, the multi-joint cooperative adjustment adaptability of existing devices is poor, and the connection matching degree of the horizontal and vertical rotation mechanisms is low, which cannot efficiently cooperate to realize complex posture adjustment, limiting its application in scenarios with high requirements for flexibility and stability, such as high-precision medical auxiliary equipment. A more reasonable and flexible multi-joint locking device is needed to solve the above problems. SUMMARY

[0022] In order to make the technical problems, technical solutions and beneficial effects of the application clearer, the application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application, and are not used to limit the application.

[0023] 8, working principle of the application: In combination Figures 1-7 , the multi-joint rotary connection all-direction adjustable locking device, through the cooperation of the horizontal rotation mechanism and the vertical rotation mechanism, realizes multi-dimensional and all-direction angle adjustment and stable locking. The horizontal rotation mechanism is responsible for the angle adjustment in the horizontal plane, and the vertical rotation mechanism undertakes the attitude change in the vertical plane. Both rely on the unified locking mechanism 200 to ensure reliable locking after adjustment.

[0024] Horizontal rotation mechanism As Figures 4-6 shown, in the horizontal rotation mechanism 100, the vertical connecting body 101 is a basic support component, and the first open slot hole 103 on the side surface thereof accommodates the locking mechanism 200. The button assembly 201 of the locking mechanism 200 interacts with the plug-in part 202: the hand pressure plate 203, the horizontal connecting plate 204 and the stop block 205 of the button assembly 201 constitute a linkage structure, and the upper end inclined surface of the stop block 205 cooperates with the 7-shaped protrusion 206 on the bottom of the plug-in part 202. When the hand pressure plate 203 is pressed, the light spring 210 is compressed, the hand pressure plate 203 drives the horizontal connecting plate 204 and the stop block 205 to displace horizontally, the inclined surface of the stop block 205 pushes the 7-shaped protrusion 206 on the bottom of the plug-in part 202, so that the plug-in part 202 moves downward, and the compression spring 209 is compressed. At this time, the first connecting plate 207 connected to the upper end of the plug-in part 202 is disengaged from the sawtooth surface of the upper connecting piece 102, and the upper connecting piece 102 can rotate horizontally relative to the horizontal rotation mechanism to adjust the angle. When the hand pressure plate 203 is released, the stop block 205 and the plug-in part 202 are reset under the action of the reset force of the light spring 210 and the elastic force of the compression spring 209, and the first connecting plate 207 is re-engaged with the sawtooth surface of the upper connecting piece 102 to lock.

When the button assembly 201 of the locking mechanism 200 is operated, the plug-in part 202 moves downward, the second connecting plate 208 is disengaged from the tooth ring 402, and the vertical connecting piece 400 can rotate vertically around the axis of the connecting rod 401 to adjust the vertical angle. When locked, the plug-in part 202 moves upward, the second connecting plate 208 is re-engaged with the tooth ring 402 to limit the vertical rotation. At the same time, the end slot 403 of the connecting rod 401 and the locking mechanism 404 arranged to rotate can further limit and fix the connecting part, thereby enhancing the stability of the vertical connection.
