Description

Technical Field

[0001] This utility model relates to the field of watch stem technology, and more particularly to a quick-release watch stem. Background Technology

[0002] A watch endlink is a component that connects the watch case and the watch band. The band is attached to the endlink, and the band can be detached from the watch case by removing the endlink. Some endlinks on the market are designed for easy removal; pressing a button retracts the pin, allowing the endlink to be removed from the case. However, because the internal parts of the endlink are movable, frequent removal and removal can lead to significant wear on these parts, causing the pin to loosen and potentially detach from the case. This necessitates timely replacement of the endlink, increasing the cost of ownership. Summary of the Invention

[0003] The problem to be solved by this utility model is to provide a quick-release watch spring to improve the service life of the spring.

[0004] To solve the above-mentioned technical problems, a quick-release watch spring bar provided by this utility model is proposed, comprising a spring bar body and a spring bar assembly. The spring bar body is provided with a strap hole. The spring bar assembly includes a button, a limiting plate, a return spring, a first pin slider, and a second pin slider. The interior of the spring bar body is provided with a movable cavity. The first and second pin sliders are symmetrically arranged in the movable cavity and can move within the movable cavity. Both the first and second pin sliders include a slider, a connecting part connected to one end of the slider, and a pin connected to the outer end face of the connecting part. Both sides of the spring bar body are provided with movable holes communicating with the movable cavity. The pins can move. The return spring is located in the movable hole, and its two ends abut against the inner end faces of the two connecting parts. The outer side of the slider is provided with a first inclined surface. The bottom of the headstock body is provided with a receiving groove that matches the limiting plate. The receiving groove is connected to the movable cavity. The limiting plate is detachably connected to the receiving groove. A through hole matching the button is provided through the limiting plate. Limiting parts are symmetrically provided on both sides of the bottom of the button. The button is movably located in the through hole. The bottom of the button is symmetrically provided with a second inclined surface that matches the first inclined surface. The second inclined surface abuts against the first inclined surface. Several first arc-shaped ribs are arranged side by side on the first inclined surface. Several second arc-shaped ribs are arranged side by side on the bottom of the slider.

[0005] Preferably, a limit post is provided on the inner end face of the connecting part, and one end of the return spring is sleeved on the limit post.

[0006] Preferably, grooves are provided on both sides of the head piece body.

[0007] Preferably, screw holes are provided on both sides of the bottom of the receiving groove, and countersunk holes corresponding to the screw holes are provided on the limiting plate, with screws connecting the countersunk holes and the screw holes.

[0008] The beneficial effects of this utility model are as follows: This utility model provides a quick-release watch spring link. In use, the watch strap is threaded through the strap hole, and the lugs on both sides of the watch case are provided with lug holes for engaging with the pins. When installing or removing the spring link from the watch case, pressing the button causes it to move along the through hole towards the movable cavity. The second inclined surface abuts against the first inclined surface, causing the first and second pin sliders to move closer together. The sliders move horizontally along the movable cavity, compressing the return spring and retracting the pins into the movable holes, facilitating the installation and removal of the spring link from the watch case. By providing a first arc-shaped rib and a second arc-shaped rib on the first inclined surface and the bottom of the slider respectively, with the second inclined surface directly contacting the first arc-shaped rib and the second arc-shaped rib directly contacting the bottom surface of the movable cavity, the arc-shaped first and second arc-shaped ribs have a small contact area, which can reduce wear, extend the service life of the first and second pin sliders, ensure good cooperation between the button and the first and second pin sliders, and prevent the spring link from loosening from the watch case, thus improving reliability.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0019] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0020] refer to Figure 1-8 .

[0021] This utility model provides a quick-release watch spring link, comprising a spring link body 1 and a spring bar assembly 2. The spring link body 1 has a strap hole 10. The spring bar assembly 2 includes a button 20, a limiting plate 21, a return spring 22, a first pin slider 23, and a second pin slider 24. The spring link body 1 has a movable cavity 11 inside. The first pin slider 23 and the second pin slider 24 are symmetrically arranged in the movable cavity 11 and can move within the movable cavity 11. The first pin slider 23 and the second pin slider 24 each include a slider 230, a connecting part 231 connected to one end of the slider 230, and a pin 232 connected to the outer end face of the connecting part 231. Both sides of the spring link body 1 have movable holes 12 communicating with the movable cavity 11. The pin 232 is movably disposed in the movable holes 12. The return spring 22... Both ends abut against the inner end faces of the two connecting parts 231. The outer side of the slider 230 is provided with a first inclined surface 230a. The bottom of the headstock body 1 is provided with a receiving groove 13 that matches the limiting plate 21. The receiving groove 13 is connected to the movable cavity 11. The limiting plate 21 is detachably connected to the receiving groove 13. A through hole 210 matching the button 20 is provided through the limiting plate 21. The bottom sides of the button 20 are symmetrically provided with limiting parts 200. The button 20 is movably disposed in the through hole 210. The bottom of the button 20 is symmetrically provided with a second inclined surface 201 that matches the first inclined surface 230a. The second inclined surface 201 abuts against the first inclined surface 230a. A plurality of first arc-shaped ribs 230b are arranged side by side on the first inclined surface 230a. A plurality of second arc-shaped ribs 230c are arranged side by side on the bottom of the slider 230.

[0022] Its working principle is as follows: When in use, the watch strap is threaded through the strap hole 10, and the lugs on both sides of the watch case are provided with lug holes that cooperate with the pin 232. When removing or installing the end links on the watch case, by pressing the button 20, the button 20 will move along the through hole 210 toward the movable cavity 11.
