[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined. "Several" means one or more, unless otherwise clearly and specifically defined.

[0030] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] See also Figures 1 to 3 The adjustment unit for adjusting the watchband of this embodiment includes: a fixing member 1, a rotating member 2, a belt particle 3 and a screw fixing assembly 4, wherein the fixing member 1 and the rotating member 2 are respectively installed on both sides of the belt particle 1 in the width direction, and the screw fixing assembly 4 connects the fixing member 1, the belt particle 3 and the rotating member 2. Specifically, the belt particle 3, the fixing member 1 and the rotating member 2 are formed with a first shaft hole channel, and the fixing member 1 and the rotating member 2 are formed with a second shaft hole channel for matching use. The screw fixing assembly 4 includes: a screw 41 that penetrates the fixing member 1 and the belt particles 3 and is screwed to the rotating member 2, an elastic member 42 that is sleeved on the screw 41 and installed in the fixing member shaft hole channel section of the fixing member 1, a limiting portion that cooperates with the screw 41 to compress and limit the elastic member 42 is formed in the fixing member shaft hole channel section, and a connecting and fixing rod 43 that includes one end fixed to the fixing member 1 and the other end detachably connected to the rotating member 2 and installed in the second shaft hole channel. More specifically, the screw 41 and the connecting and fixing rod 43 are parallel to the width direction of the watchband and are respectively located on both sides of the rotating member 2 and the fixing member 1 in the length direction of the watchband.

[0032] Specifically, if the elastic member 42 is installed in the rotating member 2, when the rotating member 2 rotates and disengages from the screw 41, a virtual position will be formed in the channel hole connecting the rotating member 2 and the screw 41. Due to the virtual position error, the difficulty of aligning the screw 41 and the rotating member 2 is increased. However, the elastic member 42 of the utility model is installed in the clamping limit portion of the fixed member 1, which effectively avoids the generation of virtual positions. During installation, accurate alignment can be achieved without adjustment, and installation is easier.

[0033] It should be noted that, in some embodiments, a fixing glue is designed between the gap between the screw 41 and the rotating part 2. After the screw 41 and the rotating part 2 are screwed together, glue is injected into the gap between the two to form the fixing glue, fix the screw 41 and the rotating part 2. This structural setting improves the stability of product assembly and overcomes the defect of loose product structure in the prior art. When adjusting the length of the strap, a set of adjustment units are usually disassembled as a whole. When the screw 41 and the rotating part 2 are assembled with interference, it is not easy to assemble if the interference is too large, and it is easy to loosen if the interference is too small. The use of fixing glue in this embodiment can further fix the screw 41 when the interference is too large or too small, improve the connection stability of the screw 41 and the rotating part 2, and facilitate the adjustment of the strap length.

[0034] In some other embodiments, laser welding may be used to fix the screw 41 and the rotating member 2. Of course, the fixing means between the two are not limited to the above two fixing means. This fixing method helps to overcome the defect of loose structure in the prior art.

[0035] The fixing member 1 in this embodiment is T-shaped, and one end of the protruding cross bar a of the fixing member 1 abuts against the rotating member 2, the belt particles 3 and the connecting fixing rod 43 are respectively located on both sides of the protruding cross bar a, and the fixing member axial hole channel section is formed in the fixing member 1 in parallel with the width direction of the strap, and a fixing member second axial hole channel section constituting the second axial hole channel is formed in the fixing member 1, and the fixing member axial hole channel section and the fixing member second axial hole channel section are respectively located on both sides of the protruding cross bar a. An internal thread matching the screw rod 41 is formed in the rotating part 2 and in the rotating part shaft hole channel section constituting the first shaft hole channel. The shaft hole channel section of the belt particle 3, the shaft hole channel section of the fixed part and the rotating part shaft hole channel section constitute the first shaft hole channel. A second shaft hole channel with a particle is also formed in the belt particle 3, which is parallel to the shaft hole channel section of the fixed part and is located on both sides of the shaft hole channel section of the fixed part on the length direction of the watch particle 3. After assembly, the second shaft hole channel with a particle and the connecting fixing rod 43 are respectively located on the left and right sides of the shaft hole channel with a particle. After assembly, the adjustment unit is in a "convex" shape.

[0036] Specifically, the two horizontal bars of the T-shaped fixing member 1 include a long horizontal bar parallel to the width direction of the watchband, and a short horizontal bar parallel to the length direction of the watchband. The width of the protruding horizontal bar is 0.04-0.06mm longer than the width of the belt particle 3, ensuring that the belt particle 3 is installed between the T-shaped fixing member 1 and the rotating member 2. Furthermore, the width of the short horizontal bar is not less than 1.8mm. Since the elastic member 42 is assembled in the short horizontal bar of the T-shaped fixing member 1, the length of the elastic member 42 in the compressed state is 0.75mm. When disassembled, the elastic member 42 rebounds to generate a stroke of 0.8mm. Therefore, the width of the short horizontal bar is not less than 1.8mm to ensure the stable installation of the elastic member 42 and the clamping limiter. The structure of the entire watchband is very compact and the design precision is high, which is conducive to improving the added value of the product.

[0037] The adjustment unit for adjusting the watchband of this embodiment, when assembled, the screw 41 is sleeved with the elastic member 42 and then passes through the fixing member 1, and the belt particle 3 is then screwed and installed in the first shaft hole channel with the rotating member 2. One end of the connecting and fixing rod 43 is fixed to the fixing member 1, and the other end is detachably connected to the rotating member 2. The structure is simple and the production cost is effectively reduced. The T-shaped structure of the fixing member 1 is helpful to improve the stability of the product. When the rotating member 2 is pulled outward, the screw 41 and the limiting part work together to compress the elastic member 42. At this time, the rotating member 2 is separated from the connecting and fixing rod 43. When a rotational force is applied to the rotating member 2, the rotating member 2 rotates around the central axis of the screw 41, and the rotating member 2 can be rotated and displaced outward at the same time. This structural setting makes the external pulling control of the rotating member 2 better and effectively overcomes the phenomenon of wear caused by rotation in the prior art.

When the rotating member 2 is pulled outward, the protruding column a is disengaged from the rotating member 2.

[0039] In this embodiment, the second connecting and fixing rod b is additionally provided, which helps to further improve the stability of product assembly.

[0040] The second connecting and fixing rod b is arranged so that the rotating member 2 ， With fixing piece 1 ， Form three connection points, specifically the rotating member 2 ， Through the screw 41 ， and T-type fixing 1 ， Connection; by connecting the fixing rod 43 ， and T-type fixing 1 ， The other side is connected; through the second connecting fixing rod b and T-shaped fixing member 1 ， The protruding crossbar a of the rotating member 2 greatly improves ， The connection stability is such that when one of the connecting rods is loose, the entire rotating part will not be damaged. ， The product has high structural strength and good stability.

[0041] Please combine Figure 5 and Figure 6 The difference between the adjustment unit for adjusting the strap of this embodiment and the above-mentioned embodiment is that the fixing member 1 ， The fixing member 1 is square-shaped. ， , the rotating member 2 ， The screw 41 ， And the connecting fixing rod 43 ， The assembly is in the shape of a "mouth".

This structural design simplifies the assembly of the product and effectively reduces the production cost of the product.

[0043] Please combine Figure 7 , assemble the adjacent adjustment units as described in 7-1, and pull the rotating member 2 outward ， When the fixing rod 43 is connected ， With rotating piece 2 ， Separation as shown in 7-2, the rotating part 2 ， After the rotational force is applied, as shown in 7-3, the screw 41 ， The elastic member 42 is compressed with the limiting portion ， , rotating member 2 ， As shown in 7-3, the connecting rod 43 is installed through ， The adjacent adjustment unit can be connected to the fixing rod 43 ， Towards rotating member 2 ， Slide the watch strap in the same direction as shown in 7-4 to complete the strap adjustment function.
