Description

Technical Field

[0001] This utility model relates to the field of watch technology, specifically to a multi-segment sliding fine-adjustment locking mechanism. Background Technology

[0002] As an important accessory that combines timekeeping and decorative functions, watches have long been integrated into daily life. The watch strap is a key component connecting the watch to the wrist, and its comfort and fit directly affect the user experience. Most existing watch straps have adjustment functions, and some even have micro-adjustment functions, aiming to provide users with a more precise wearing experience.

[0003] When making fine adjustments, users need to use a professional watchband removal tool to push out the pin connecting the watch link and the adjustment hole. Because the pin is small and tightly fitted, it is easy for it to bend or be lost during the process, and it may also damage the watch link and the adjustment hole. After adjusting the watch link position, the user needs to reinsert the pin and secure it. Improper installation can lead to the watchband becoming loose or coming undone, affecting wearing safety and comfort, and making the operation inconvenient. Therefore, we propose a multi-stage sliding fine-adjustment locking mechanism. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, one objective of this invention is to propose a multi-segment sliding fine-tuning locking mechanism. This design eliminates the traditional method of adjustment via a locking pin, eliminating the need for complex disassembly tools and avoiding the inconvenience and risks associated with locking pin operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-segment sliding fine-adjustment locking mechanism includes a mounting bracket with an open top and multiple adjustment holes on both sides of the mounting bracket near the front.

[0007] An adjustment assembly is provided at the front side of the opening of the mounting bracket. The adjustment assembly includes an adjustment seat that is slidably installed in the opening of the mounting bracket. The bottom of the adjustment seat has a mounting cavity, and the bottom of the mounting cavity is equipped with a removable cover plate. A gear is rotatably installed at the center of the mounting cavity. Movable plates are provided on both the front and rear sides of the gear. The side wall of the movable plate near the gear has a tooth groove that meshes with the gear.

[0008] Inside the mounting cavity, guide rods are fixed on both the front and rear sides. Springs are fitted at both ends of the guide rods. Limiting rings for pressing against the springs are coaxially fixed on the outer wall of the guide rods near both ends. A slider is slidably installed between the ends of the two guide rods. An adjusting head is fixed on the two opposite ends of the two sliders. The adjusting head passes through the outer wall of the adjusting seat and is inserted into the corresponding adjusting hole. The end of the movable plate is fixedly connected to the slider.

[0009] The front end of the adjustment seat has a connecting groove, and a watch strap link is hinged to the connecting groove.

[0010] In addition, the multi-segment sliding fine-tuning locking mechanism proposed in the application may also have the following additional technical features:

[0011] Specifically, the two inner side walls of the mounting bracket opening are fixed with limit plates at the top front end, and the bottom of the limit plates is provided with limit grooves, the front end of the limit grooves being closed; the top two ends of the adjusting seat are fixed with limit blocks, and the limit blocks are slidably connected with the corresponding limit grooves.

[0012] Specifically, the mounting bracket has a U-shaped cross-section and a concave arc shape at the top.

[0013] Specifically, the mounting bracket has connection holes for connecting the watch buckle on both the left and right side walls near the rear side, and a mounting groove for installing the watch buckle clip is provided on the front side of the connection hole.

[0014] Specifically, the cross-sectional shape of the adjustment holes is circular, and the adjustment holes are linearly and equally spaced in the horizontal direction.

[0015] Specifically, the cross-sectional shape of the adjustment seat is U-shaped, and the size of the adjustment seat is adapted to the opening size of the mounting bracket.

[0016] Specifically, the size of the cover plate is adapted to the size of the mounting cavity, and the cover plate is tightly bonded to the adjusting seat.

[0017] Specifically, the slider and the adjusting head are integrally formed, and the overall shape of the adjusting head is cylindrical.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The adjustable mechanism allows for precise adjustment of the watchband length using an Allen wrench. This wrench, connected to a gear, drives the gear to rotate. The gear's rotation, in turn, causes two meshing movable plates to move synchronously and relative to each other. This movement pulls on two sliders on either side of the movable plates, which are connected to the adjustment head. The sliders' movement disengages the adjustment head from its current adjustment hole. The adjustment seat can then be moved to the desired position within the watchband. Releasing the Allen wrench activates a pre-installed spring, which pushes the slider and adjustment head back to their initial positions, allowing the adjustment head to re-insert into the corresponding adjustment hole. This coordinated mechanical operation achieves precise adjustment of the adjustment seat's position, thus enabling fine-tuning of the watchband length. This design eliminates the need for traditional pin-operated adjustments, avoiding the inconvenience and risks associated with pin-operated methods. The entire adjustment process is simple and quick, significantly reducing the difficulty of adjusting the watch band and providing users with a more efficient and convenient experience in fine-tuning the watch band.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This embodiment provides a technical solution:

[0032] Please see Figures 1-6 As shown, the multi-segment sliding fine-tuning locking mechanism includes a mounting frame 1. The top of the mounting frame 1 is open, and multiple adjustment holes 12 are provided on both side walls of the mounting frame 1 near the front. An adjustment component 2 is provided on the front side of the opening of the mounting frame 1. The adjustment component 2 includes an adjustment seat 20 slidably installed in the opening of the mounting frame 1. A mounting cavity 201 is provided at the bottom of the adjustment seat 20, and a removable cover plate 21 is installed at the bottom of the mounting cavity 201. A gear 22 is rotatably installed at the center of the mounting cavity 201. Movable plates 24 are provided on both the front and rear sides of the gear 22. The side wall of the movable plate 24 near the gear 22 has a tooth groove that meshes with the gear 22. 240; Inside the mounting cavity 201, guide rods 26 are fixed on both the front and rear sides. Springs 27 are sleeved on both ends of the guide rods 26. Limiting rings 260 for pressing against the springs 27 are coaxially fixed on the outer wall of the guide rods 26 near both ends. Sliding sliders 25 are slidably installed between the ends of the two guide rods 26. Adjusting heads 250 are fixed on the two opposite ends of the two sliders 25. The adjusting heads 250 pass through the outer wall of the adjusting seat 20 and are inserted into the corresponding adjusting holes 12. The end of the movable plate 24 is fixedly connected to the slider 25. A connecting groove 200 is opened at the front end of the adjusting seat 20. A watch strap link 3 is hinged at the connecting groove 200.

[0033] In this embodiment, limit plates 13 are fixed to both sides of the opening of the mounting frame 1 at the top front end. Limit plates 13 have limit grooves 130 at their bottom, and the front ends of the limit grooves 130 are closed. Limit blocks are fixed to both ends of the top of the adjusting seat 20, and these limit blocks are slidably connected to the corresponding limit grooves 130. The slidable connection between the limit blocks at the top of the adjusting seat 20 and the limit grooves 130 ensures that the adjusting seat 20 can only move in a specified direction, preventing it from shaking or shifting within the mounting frame 1 and ensuring stability during the adjustment process. This design also prevents the adjusting seat 20 from detaching from the mounting frame 1.

[0034] In this embodiment, the mounting bracket 1 has a U-shaped cross-section and a concave arc-shaped top. The U-shaped cross-section design provides a stable mounting space for the adjustment component 2, which can better accommodate components such as the adjustment seat 20. The concave arc-shaped top is ergonomic, which can improve wearing comfort, make the mounting bracket 1 fit more closely to the wrist, reduce the pressure on the wearer, and improve the user experience of the product.

[0035] In this embodiment, the left and right side walls of the mounting bracket 1 are provided with connection holes 10 for connecting the watch buckle near the rear side, and the front side of the connection hole 10 is provided with a mounting groove 11 for installing the watch buckle clip. This design facilitates the installation and removal of the watch buckle, can adapt to different types of watch buckles, increases the versatility and practicality of the product, and allows users to replace the watch buckle according to their own needs, thus improving the flexibility of the product.

[0036] In this embodiment, the adjustment holes 12 have a circular cross-sectional shape and are linearly and equally spaced in the horizontal direction. The circular cross-section of the adjustment holes 12 fits tightly with the cylindrical adjustment head 250, effectively preventing the adjustment head 250 from shaking. The linear and equally spaced distribution allows the adjustment seat 20 to achieve uniform and precise fine-tuning during adjustment, making it convenient for users to accurately adjust the strap length as needed, thus improving the accuracy and convenience of adjustment.

[0037] In this embodiment, the adjusting seat 20 has a U-shaped cross-section, and its dimensions are adapted to the opening size of the mounting bracket 1. This matching opening size design allows the adjusting seat 20 to slide smoothly within the mounting bracket 1. This matching design ensures a tight fit between the adjusting seat 20 and the mounting bracket 1, making the adjustment process more stable, avoiding shaking caused by excessive gaps, and improving the stability of the mechanism.

[0038] In this embodiment, the size of the cover plate 21 is adapted to the size of the mounting cavity 201, and the cover plate 21 is tightly bonded to the adjusting seat 20. This design effectively protects components such as the gear 22 and the movable plate 24 inside the mounting cavity 201. It prevents dust and debris from entering, extends the service life of the components, and also ensures the normal operation of the internal mechanism, thereby improving the reliability of the entire adjusting assembly 2.

[0039] In this embodiment, the slider 25 and the adjusting head 250 are integrally molded, and the overall shape of the adjusting head 250 is cylindrical. This integral molding structure ensures a secure connection between the slider 25 and the adjusting head 250, preventing loosening or damage due to a loose connection. The cylindrical adjusting head 250 fits well with the circular adjusting hole 12, allowing for smoother insertion and removal, making the adjustment operation easier and more efficient, and improving the convenience of adjustment.

[0040] It should be added that a connecting post 23 is coaxially keyed to the top of gear 22. The connecting post 23 passes through the top of the adjusting seat 20 and is rotatably connected to the adjusting seat 20. The top of the connecting post 23 has an adjustment groove 230 in the shape of a regular hexagon. The key connection ensures stable power transmission and allows gear 22 and connecting post 23 to rotate synchronously. The regular hexagonal adjustment groove 230 is compatible with an internal hex wrench, making it easy for users to operate and precisely control the rotation of gear 22, thereby achieving precise fine-tuning of the watch strap length.

[0041] It is understandable that a fixed block 241 is fixed to the side wall of the movable plate 24 away from the gear 22, and the guide rod 26 passes through the fixed block 241 and is slidably connected to the fixed block 241. This design guides the horizontal movement of the movable plate 24 through the cooperation of the guide rod 26 and the fixed block 241, thereby ensuring the stability and smoothness of the movement of the movable plate 24.

[0042] When the user needs to adjust the watch strap length, an Allen wrench is inserted into the hexagonal adjustment slot 230 at the top of the connecting post 23. The user rotates the connecting post 23 with the Allen wrench. Due to the key connection, the connecting post 23 drives the gear 22 to rotate synchronously. Since the side wall of the movable plate 24 near the gear 22 has a toothed groove 240, the movable plate 24 moves away from its initial position under the interaction of the toothed groove 240 and the gear 22. Since the end of the movable plate 24 is fixedly connected to the slider 25, the movable plate 24 drives the slider 25 to move synchronously. During the movement of the slider 25, the spring 27 is compressed. The adjusting head 250, fixed to the opposite end face of the slider 25, gradually disengages from the currently inserted adjusting hole 12 as the slider 25 moves. Once the adjusting head 250 is completely disengaged from the adjusting hole 12, the user simultaneously slides the adjusting seat 20 within the opening of the mounting bracket 1. When the adjusting seat 20 moves to the desired position, the user releases the Allen wrench. The compressed spring 27 releases its elastic potential energy, pushing the slider 25 along the guide rod 26 to move in the opposite direction to its initial position. Since the slider 25 is fixedly connected to the movable plate 24, the movable plate 24 also moves in the opposite direction, thereby driving the adjusting head 250 to move towards the adjusting hole 12. Finally, the adjusting head 250 is reinserted into the corresponding adjusting hole 12, completing the fixation of the adjusting seat 20 within the mounting bracket 1. At this time, the position of the watch strap link 3, hinged to the front connecting groove 200 of the adjusting seat 20, also changes accordingly, thus achieving fine-tuning of the watch strap length.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
