Detailed Implementation

[0018] The technical solutions claimed in this invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] See Figures 1 to 6 As shown, a transmission mechanism with a buffer function in this embodiment includes a transmission component and a buffer component 2.

[0020] The transmission assembly includes a transmission rod 11, a guide rail 12 for guiding the transmission rod 11 to slide, and a transmission box 13 for driving the transmission rod 11 to slide along the guide rail 12. In this embodiment, the transmission box 13 includes a box body, a transmission shaft 132 housed within the box body and rotatably connected to the box body, a steering plate 133 housed within the box body and slidably connected to the box body, and a connecting rod 134. The transmission rod 11 is connected to components such as a lock seat or locking point. During sliding, the transmission rod 11 can drive the lock seat or locking point to move, thereby achieving unlocking or unlocking. Furthermore, in this embodiment, the transmission shaft 132 can be connected to operating components such as a handle.

[0021] The connecting rod 134 is hinged at both ends to the drive shaft 132 and the steering plate 133, respectively. The steering plate 133 is also fixedly connected to the drive rod 11. The housing includes a first cover 131a and a second cover 131b forming two sides of the housing. The first cover 131a and the second cover 131b are connected by a fixing pin. The housing is composed of the first cover 131a and the second cover 131b for easy installation. The housing has a guide groove 1311 for guiding the steering plate 133 to slide. The guide groove 1311 can guide the steering plate 133 to slide horizontally.

[0022] The buffer assembly 2 includes a sleeve 21, a slider 22 slidably connected inside the sleeve 21, and a return spring 23 disposed inside the sleeve 21 and driving the slider 22 to slide towards the transmission box 13. The sleeve 21 is fixedly connected to the guide rail 12, and the transmission rod 11 is fixedly connected to the slider 22. Specifically, the transmission rod 11 is formed with a hook 111, and the slider 22 is provided with a groove 221 that cooperates with the hook 111.

[0023] In this embodiment, the transmission mechanism is used as follows: When the handle rotates, it drives the transmission shaft 132 to rotate, and through the transmission action of the connecting rod 134, it drives the steering piece 133 to slide, causing the transmission rod 11 to slide synchronously. When the transmission shaft 132 rotates clockwise, the transmission rod 11 is driven to slide downward, and at the same time, the lock seat or locking point component on the transmission rod 11 descends synchronously away from the locked position, thereby unlocking. During the descent of the transmission rod 11, it drives the slider 22 inside the sleeve to move downward. During this process, the return spring 23 buffers the impact force of the slider 22 to achieve a buffering effect.

[0024] When the drive shaft 132 rotates counterclockwise, the drive rod 11 is driven to slide upward, and the lock seat or locking point component on the drive rod 11 rises synchronously to return to its original position to achieve locking. During this process, the slider 22 inside the sleeve 21 moves upward, and the return spring 23 extends to restore its original position.

[0025] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make more possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, all equivalent changes made based on the concept of the present invention without departing from the scope of the present invention should be covered within the protection scope of the present invention.
