Abstract
Description
Technical Field
[0001] This utility model belongs to the field of watch technology, and in particular relates to a quick-release structure for watch head links. Background Technology
[0002] In the watchmaking industry, end links are a crucial component of a watch, and their connection structure with the case directly affects the watch's assembly efficiency, ease of use, and stability. Traditional methods of connecting end links to the case are relatively complex, requiring specialized tools for assembly and disassembly. This is not only inefficient but also prone to damaging the watch during the process.
[0003] With the continuous development of the watch industry, quick-release front links with a push-button mechanism have emerged to improve the efficiency of front link assembly and disassembly. These quick-release front links change the connection structure between the front link and the watch case by pressing a specific part, thus enabling rapid assembly and disassembly. While this structure improves assembly and disassembly efficiency to some extent, it also has some obvious drawbacks.
[0004] On the one hand, the quick-release lead links with a push-button mechanism require a high degree of operational precision. In actual use, due to the small size of the watch and the limited space in the push-button area, users are prone to either not pressing the button properly or pressing it too hard. Insufficient pressing may prevent the lead link from being completely disconnected from the case, affecting the disassembly and assembly process; while excessive pressing may damage the push-button mechanism or the connecting parts between the lead link and the case, reducing the watch's lifespan.
[0005] On the other hand, push-button quick-release links pose a risk of accidental opening and closing. During daily wear or carrying, the watch may be subjected to various external forces such as pressure or impact. If the push-button part of the quick-release link is accidentally pressed, the link may open unexpectedly, causing the watch to fall off.
[0006] Furthermore, existing push-button quick-release links typically only fit specific watch case styles and sizes, resulting in poor versatility. When the watch style or case size changes, a matching quick-release link needs to be replaced, increasing production and usage costs.
[0007] Therefore, the inventors dedicated themselves to designing a watch head link disassembly and assembly structure to solve the above problems. Utility Model Content
[0008] The purpose of this utility model is to provide a quick-release structure for watch stems that not only has low requirements for operational precision, but also allows for quick assembly and disassembly, is easy to operate, prevents accidental pressing, and is highly versatile.
[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0015] As an improvement to the quick-release structure of the watch head of this utility model, the side of the slide sleeve is provided with multiple limiting grooves at intervals, and any one of the limiting grooves is matched with the spring pin in the slide cavity for limiting.
[0016] As an improvement to the quick-release structure of the watch head link of this utility model, the head link includes a head link body and a gasket. The gasket covers the opening of the head link body to form the sliding cavity, and the sliding member passes through the through hole on the gasket.
[0017] As an improvement to the quick assembly / disassembly structure of the watch head of this utility model, the gasket is provided with two limiting platforms, the two limiting platforms are located in the sliding cavity and are spaced apart to form a sliding channel, and the part of the slider extending into the sliding cavity is located in the sliding channel.
[0018] As an improvement to the quick-release structure of the watch head link of this utility model, a spring pin is inserted into the inner wall of the limiting platform, and the ball of the spring pin elastically presses against the sliding member and engages with any limiting groove on the sliding member.
[0019] As an improvement to the quick-release structure of the watch head link of this utility model, the hinge end of the watch case is provided with multiple pairs of hinge holes, and the number of sliding pins is one pair. The pair of sliding pins are coaxially arranged and hinged to any pair of hinge holes.

The head link 2 is provided with a slider 3. One end of the slider 3 is slidably received in the sliding cavity 7 of the head link 2, and the other end of the slider 3 passes through the head link 2 and forms a pushing part on the outside of the head link 2. The sliding pin 4 is elastically and slidably connected to the head link 2, and the part of the sliding pin 4 located inside the head link 2 elastically abuts against the slider 3.
[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The two corresponding hinge ends of the watch case 1 are both U-shaped. The head link 2 is located in the groove of the hinge end of the watch case 1. Multiple pairs of hinge holes 11 are provided on the side wall of the groove of the hinge end of the watch case 1 to facilitate the adjustment of the position of the head link 2. In this embodiment, two pairs of hinge holes 11 are preferred, and the same pair of hinge holes 11 are coaxially arranged.
[0038] Reference Figures 3 to 11The head pellet 2 includes a head pellet body 21 and a gasket 22. The bottom of the head pellet body 21 is hollowed out to form an opening, and the top of the head pellet body 21 is provided with an installation groove. The head pellet body 21 is provided with a pair of sliding holes 211, which are coaxially arranged and located on two corresponding sides of the head pellet body 21. The gasket 22 is elongated and is fixedly covered at the opening at the bottom of the head pellet body 21 to form the sliding cavity 7. Two limiting platforms 222 are provided on the end face of the gasket 22 near the head pellet body 21. The two limiting platforms 222 and the gasket 22 are integrally made of the same material. The molding process involves two limiting platforms 222 located within the sliding cavity 7 and spaced apart to form a sliding channel. A spring pin 5 is inserted into the inner wall of each limiting platform 222, and one end face of the spring pin 5 has a ball 51. The two spring pins 5 are coaxially arranged, and the ball 51 of each spring pin 5 points to the spring pin 5 on the corresponding side, so that the ball 51 of the two spring pins 5 is located on the limiting inner wall of their respective limiting platforms 222. A through hole 221 is also provided in the center of the gasket 22, which is located between the two limiting platforms 222. The through hole 221 communicates with the sliding cavity 7 and is located at the bottom of the sliding cavity 7.
[0039] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 In this embodiment, the number of sliding pins 4 is preferably a pair. The pair of sliding pins 4 are coaxially symmetrically arranged and hinged to any pair of hinge holes 11. Specifically, one end of each sliding pin 4 is located in the opening of the headstock body 21 and is elastically connected to the headstock body 21 through a spring 41. The spring 41 is located in the opening of the headstock body 21 and is sleeved on the sliding pin 4. The other end of the sliding pin 4 slides through the sliding hole 211 of the headstock body 21 and is inserted into the corresponding hinge hole 11 of the watch case 1 to realize the hinge between the headstock body 21 and the watch case 1. Each sliding pin 4 slides in the corresponding sliding hole 211 along its axial direction. The sliding direction of the sliding member 3 is perpendicular to the sliding direction of the sliding pin 4. The end part of each sliding pin 4 extending into the headstock body 21 is hemispherical.

The sliding sleeve 31 is located in the sliding cavity 7 and connected to the pushing member 32. The sliding sleeve 31 is slidably disposed in the sliding channel formed by two limiting platforms 222 spaced apart (i.e., the sliding sleeve 31 is located between the two limiting platforms 222). Multiple limiting grooves 311 are provided on two corresponding sides of the sliding sleeve 31. Multiple limiting grooves 311 on the same side are spaced apart. In this embodiment, the number of limiting grooves 311 on the same side of the sliding sleeve 31 is preferably two. The ball bearings 51 of the two spring pins 5 elastically press against the sliding member 3 and are limited and engaged with any two limiting grooves 311 on the corresponding side of the sliding sleeve 31, so that the part of the sliding member 3 located in the sliding cavity 7 is limited and connected to the sliding cavity 7. The ball bearings 51 can switch between the two limiting grooves 311 on the same side. An inclined pushing surface 312 is provided at the two corners of the sliding sleeve 31.

[0041] Reference Figure 1 , Figure 2 and Figure 3 A decorative piece 6 is also fixed in the mounting groove at the top of the head piece 21.
[0042] Reference Figures 1 to 12 The disassembly and assembly method of the quick-release structure for the watch head link of this utility model is as follows:
[0043] When it is necessary to remove the head link 2, manually push the pusher 32 outward (i.e., away from the case 1). The pusher 32 moves outward a certain distance under the limiting action of the through hole 221. The sliding sleeve 31 slides outward in the sliding channel of the head link along with the pusher 32 until the ball 51 of the two spring pins 5 switches into the limiting groove 311 of the sliding sleeve 31 near the end of the case 1. At this time, the sliding sleeve 31 moves away from the two sliding pins 4. The two sliding pins 4 retract into the head link 2 under the push of their respective springs 41, and the entire head link 2 can be removed.
[0044] When the head link 2 needs to be installed, the user only needs to manually push the pusher 32 inward (i.e., towards the watch case 1). The pusher 32 moves inward a certain distance under the limiting action of the through hole 221. The sliding sleeve 31 slides inward in the sliding channel of the head link along with the pusher 32 until the ball bearings 51 of the two spring pins 5 switch to the limiting groove 311 of the sliding sleeve 31 away from the end of the watch case 1. At this time, the sliding sleeve 31 approaches the two sliding pins 4, the spring 41 is compressed, and the two inclined push surfaces 312 of the sliding sleeve 31 push the two sliding pins 4 to slide outward and extend, and then extend into the corresponding hinge hole 11 of the watch case 1. At this time, the head link 2 is hinged to the watch case 1, and the head link 2 is installed.
[0045] Since the hinge end of the watch case 1 of this utility model is provided with two pairs of hinge holes 11, a pair of sliding pins 4 on the headstock 2 can cooperate with any pair of hinge holes 11 to adjust the hinge position between the headstock 2 and the watch case 1.
[0046] This invention relates to a quick-release watch head link structure that enables rapid assembly and disassembly, is easy to operate, prevents accidental pressing, and is highly versatile. The quick-release watch head link structure uses the sliding member 3 to slide back and forth, controlling the extension and retraction of the sliding pin 4 to complete the assembly and disassembly of the head link 2 from the watch case 1. This structure adapts to different watch case sizes, enabling rapid assembly and disassembly and significantly improving efficiency. Simultaneously, it avoids the potential risk of accidental opening and closing caused by press-type quick-release head link structures, thus achieving a foolproof function.
[0047] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
