Description

Technical Field

[0001] The utility model relates to the field of watches, in particular to a quick-release watch band link. Background Art

[0002] Reference Figure 1 , the common metal watch bands on the market are usually composed of a number of links connected together. The links can rotate freely to achieve a comfortable wearing effect that fits the wrist. The beads that make up the links of this metal watch band are fixed horizontally (the horizontal direction refers to the width direction of the watch band). For example, Figure 1 the horizontal fixation mainly relies on a roll pin 1, a split pin 2, and a male-female connection 3. This fixation method can ensure that the horizontal gap between the links is not too large, causing the watch band to be loose. Consumers have different wrist thicknesses, and the length of the watch band needs to be adjusted according to individual differences. The connections between the links and between the beads that make up the links commonly use parts such as screws, roll pins, male-female connections, and split pins. The disassembly of these connecting parts requires professional personnel to use special tools. The relatively stable connection method mentioned above results in consumers being unable to adjust the length of the watch band by themselves, bringing a bad experience to consumers.

[0003] The above information disclosed in this background section is only included to enhance the understanding of the background of the present disclosure, and thus may include information that does not form the prior art already known to those of ordinary skill in the art at present. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a quick-release watch band link to enable consumers to conveniently disassemble and assemble the links and freely adjust the length of the watch band, aiming at the problem and defect that the links of the common metal watch band are inconvenient to remove when adjusting the length in the prior art.

[0035] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The typical embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive. It should be understood that the embodiments of the present utility model and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the embodiments of the present utility model and the technical features in the embodiments can be combined with each other.

[0036] Reference Figure 2-4 , the quick-release watch strap joints of the present utility model are sequentially connected to form a watch strap. The direction of sequential connection of each joint is the length direction of the watch strap. The width direction of the watch strap is perpendicular to the length direction of the watch strap. In this embodiment, the length direction of the watch strap is defined as the front-back direction, and the width direction of the watch strap is defined as the left-right direction.

[0037] The structure of a single said joint can be referred to Figure 2 , a single joint includes a middle bead 100 and two side beads connected to the left and right sides of the 100. The two side beads are divided into a first side bead 200 and a second side bead 300. The first side bead 200 and the second side bead 300 are disposed opposite to each other in the left-right direction (i.e., the width direction of the watch strap), and are both disposed offset from the middle bead 100. The portions where the first side bead 200 and the second side bead 300 protrude offset from the middle bead 100 are used to connect to the next joint, and the portions where the 100 protrudes offset from the first side bead 200 and the second side bead 300 are used to connect to the previous joint.

[0038] The idea of the present utility model is that, on the one hand, the first side bead 200 and the second side bead 300 and the middle bead 100 of other joints are movably strung together through a removably taken-out inter-node connector 401; on the other hand, the middle bead 100 is elastically connected to the first side bead 200 or / and the second side bead 300, so that the first side bead 200 or / and the second side bead 300 can be pulled away from the middle bead 100 to increase the distance between the first side bead 200 and the second side bead 300 for taking out or inserting the inter-node connector 401 connecting other joints.

[0039] In this embodiment, the middle bead 100 is only elastically connected to the first side bead 200, and the middle bead 100 is fixedly connected to the second side bead 300 rather than elastically. Of course, in other embodiments, the middle bead 100 can be elastically connected to both side beads with reference to the way of this embodiment, which belongs to a simple deformation of this embodiment and is also within the protection scope of the present utility model.

[0040] Among them, the middle bead 100 and the second side bead 300 are mainly fixedly connected through the first belt section inner pin 404 and the second belt section inner pin 405. The middle bead 100 and the first side bead 200 are mainly elastically connected through the screw 402 and the spring 403 and movably connected through the third belt section inner pin 406, so that the first side bead 200 can neither break away from the connection of the middle bead 100 nor move a certain distance.

[0041] In this embodiment, the elastic connection between the middle bead 100 and the first side bead 200 is realized based on the screw 402 and the spring 403. The screw 402 movably passes through the middle bead 100 in the width direction of the watch band and is threadedly connected to the corresponding side bead 200. And the displacement between the screw 402 and the middle bead 100 is restricted by the spring 403 in the width direction of the watch band. The spring 403 provides a pre-tightening force in the width direction of the watch band. The pre-tightening force makes the side bead 200 connected by the screw 402 approach the middle bead 100. Pulling the side bead 200 can change the compression amount of the spring 403. In this way, the side bead 200 of the belt section can be pulled apart and reset, changing the matching width of the belt section.

[0042] Reference Figure 3 , the middle bead 100 is provided with a first straight through hole 101, a second straight through hole 102, and a stepped hole 103. The straight through hole refers to a through hole with a constant aperture, and the stepped hole is a countersunk hole. The first straight through hole 101, the second straight through hole 102, and the stepped hole 103 all extend in the width direction of the watch band, and the first straight through hole 101, the second straight through hole 102, and the stepped hole 103 are arranged at intervals in the length direction of the watch band in sequence. Among them, the first straight through hole 101 is opened at the part of the middle bead 100 protruding misaligned relative to the first side bead 200 and the second side bead 300, and the second straight through hole 102 and the stepped hole 103 are opened at the part of the middle bead 100 located between the first side bead 200 and the second side bead 300.

[0043] The first side bead 200 is provided with a first connection hole 201 extending in the width direction of the watch band, a threaded hole 202 matching the screw 402, and a fifth connection hole 203. And only the first connection hole 201 is opened at the part of the first side bead 200 protruding misaligned relative to the middle bead 100. The first connection hole 201, the fifth connection hole 203, and the threaded hole 202 are all blind holes.

[0044] The second side bead 300 is provided with a second connection hole 301, a third connection hole 302, and a fourth connection hole 303 that extend along the width direction of the watch band, and only the second connection hole 301 is provided at a position where the second side bead 300 protrudes out of alignment with the middle bead 100. The second connection hole 301, the third connection hole 302, and the fourth connection hole 303 are all blind holes.

[0045] The spring 403 is sleeved outside the screw 402 and abuts between the step of the screw 402 and the step of the stepped hole 103. Specifically, the screw 402 includes a cylindrical connection portion and a cylindrical head with a diameter larger than that of the connection portion. An external thread is provided at one end of the connection portion away from the head. The stepped hole 103 includes a small hole and a large hole with a diameter larger than that of the small hole. The radial dimensions of the large hole and the small hole of the stepped hole 103 match the radial dimensions of the head and the connection portion of the screw 402 respectively. The entire head is located in the large hole. The connection portion passes through the large hole and the small hole at the same time, and its external thread passes out of the small hole and is threadedly engaged with the threaded hole 202. The spring 403 is sleeved outside the connection portion. One side of the head connected to the connection portion serves as a step to abut against one end of the spring 403, and a step is formed at the connection between the large hole and the small hole to abut against the other end of the spring 403.

[0046] The inter-link connector 401 is a key pin, whose length is longer than the dimension of the middle bead 100 in the width direction of the watch band and shorter than the dimension of the link in the width direction of the watch band. The inter-link connector 401 passes through the first straight through hole 101 of one link, and both ends of the inter-link connector 401 are inserted into the first connection hole 201 and the second connection hole 301 on both sides of another link respectively. That is, adjacent single links are connected by a key pin. Since the length of the key pin is slightly longer than the length L of the middle bead 100, when disassembling, a single link can be easily taken out. For example, just pull one side bead 200 of the link away from the middle bead 100 by a certain distance, and then pull the other connected links in the same direction to make the other links disengage and be taken out from the whole watch band. After removing several links according to the size of the wrist and reconnecting them, the adjustment of the watch band length can be completed.

[0047] In addition to being used to cooperate with the screw 402, the stepped hole 103 is also used to cooperate with the pin 404 inside the first belt section. Specifically, the third connection hole 302 is aligned with the large hole of the stepped hole 103. The pin 404 inside the first belt section is a double-stage rolling pin. One end of the pin 404 inside the first belt section is knurled and fixedly connected to the third connection hole 302, and the other end is knurled and fixedly connected to the large hole of the stepped hole 103. The length of the pin 404 inside the first belt section is shorter than the length of the pin 405 inside the second belt section, mainly to leave enough moving space for the screw 402 and the spring 403.

[0048] The pin 405 inside the second belt section is fixedly connected to the second straight through hole 102 and the fourth connection hole 303 respectively. Specifically, the pin 405 inside the second belt section is also a double-stage rolling pin. One end of the pin 405 inside the second belt section is knurled and fixedly connected to the second straight through hole 102, and the other end is knurled and fixedly connected to the fourth connection hole 303.

[0049] The pin 406 inside the third belt section is movably inserted into the second straight through hole 102 and fixedly connected to the fifth connection hole 203. Specifically, the pin 406 inside the third belt section is a single-stage rolling pin and the knurled end is fixedly connected to the fifth connection hole 203, and the other end is movably inserted into the second straight through hole 102.

[0050] As Figure 5 shown, when it is necessary to disassemble the belt section, pull down the first side bead 200, and the screw 402 moves downward to compress the spring 403, as shown in state A in the figure; while maintaining the downward pulling force of the first side bead 200, take out the middle bead 100 downward, as shown in state B in the figure; then cancel the downward pulling force on the side bead 200 to release the side bead 200, and the side bead 200 resets under the action of the spring 403, completing the disassembly of a single belt section, as shown in state C in the figure.

[0051] As Figure 6 shown, when it is necessary to assemble the belt section, pull down the first side bead 200, and the screw 402 moves downward to compress the spring 403, as shown in state A in the figure; while maintaining the downward pulling force of the first side bead 200, insert the middle bead 100 upward, as shown in state B in the figure; then cancel the downward pulling force on the side bead 200 to release the side bead 200, and the side bead 200 resets under the action of the spring 403, completing the assembly of a single belt section, as shown in state C in the figure.

[0052] It can be understood that in other embodiments, if both side beads 200 and 300 are changed to be elastically connected to the middle bead 100, then only the side bead 300 needs to be connected to the middle bead 100 in the same way as the side bead 200. Of course, at this time, the middle bead 100 also needs to design corresponding stepped holes for the side bead 300, and the double-stage rolling pins also need to be changed to single-stage rolling pins accordingly.

[0053] When using the strap link of this embodiment, there is no need to find a professional or use professional tools when disassembling and assembling the strap link. Relying on the unique structure with ingenious design, consumers can adjust the length of the strap according to the thickness of their wrists by themselves. This embodiment also has the advantages of stable structure and controllable cost, which greatly improves the consumer experience.
