[0031] The utility model provides a watch strap fixing mechanism. Figures 1 to 3 This is a specific embodiment of the watchband fixing mechanism provided by the utility model.

[0032] Reference Figures 1 to 3 The strap fixing mechanism includes: a carrier 1 for carrying a strap 3, the carrier 1 including a first carrier block 11 and a second carrier block 12, the strap 3 having a plane structure 31 and a curved surface structure 32, the first carrier block 11 having a first plane 111 for fitting with the plane structure 31, the second carrier block 12 having a first curved surface 121 for fitting with the curved surface structure 32; a pressing member 2 including a first pressing block 21 and a second pressing block 22, the positions of the first pressing block 21 and the second pressing block 22 are respectively aligned with the first The carrier block 11 and the second carrier block 12 correspond to each other, the first pressure block 21 is provided with a second plane 211 for abutting against the plane structure 31, and the second pressure block 22 is provided with a second curved surface 221 for abutting against the curved structure 32; a driving member drives and connects the first pressure block 21 and the second pressure block 22, and the driving member is used to drive the first pressure block 21 to move toward the first carrier block 11 to fix the plane structure 31 and drive the second pressure block 22 to move toward the second carrier block 12 to fix the curved structure 32.

[0033] See also Figure 1 ,by Figure 1 As shown in the example, the first pressing block 21 is disposed on the upper side of the first carrier block 11 , and the second pressing block 22 is disposed on the right side of the first pressing block 21 .

[0034] In this embodiment, the planar structure 31 of the strap 3 is fixed by the first carrier block 11 and the first pressure block 21, and the curved structure 32 of the strap 3 is fixed by the second carrier block 12 and the second pressure block 22, which can ensure that the strap 3 is firmly fixed and avoid the strap 3 from shifting during the assembly process; the first plane 111 and the second plane 211 can fit tightly with the planar structure 31, and the first curved surface 121 and the second curved surface 221 can fit tightly with the curved structure 32, which can increase the contact area and evenly distribute the pressure, which can further improve the fixing stability of the strap 3.

[0035] Furthermore, the first carrier block 11 is provided with a plurality of limiting posts 13, each of which forms a limiting space for accommodating the watchband 3. In this embodiment, after the watchband 3 is placed in the limiting space and before the first and second pressure blocks 21 and 22 are pressed downward, the limiting posts 13 can initially limit the position of the watchband 3, preventing the watchband 3 from shifting, thereby ensuring the precise position of the watchband 3 after it is fixed. Specifically, the number of limiting posts 13 is set to six, and the six limiting posts 13 are divided into two groups, each of which contains three limiting posts 13. The two groups of limiting posts 13 are respectively provided on the front and rear sides of the watchband 3 and abut against the watchband 3.

[0036] Furthermore, a column seat 14 is provided at the bottom end of the first carrier block 11, and the limiting column 13 is provided on the column seat 14. A through hole 15 is provided on the first carrier block 11 for the limiting column 13 to pass upward. In this embodiment, by arranging the limiting column 13 on the column seat 14 instead of directly arranging it on the first carrier block 11, it is easy to process, and the column seat 14 can be adjusted and designed according to different application requirements, which is more flexible and adaptable to different working environments. Specifically, two column seats 14 are provided at the bottom of the first carrier block 11, and two groups of limiting columns 13 are respectively arranged on the two column seats 14. The width of the through hole 15 is greater than the outer diameter of the limiting column 13 to reserve space for adjusting the position of the limiting column 13.

[0037] Furthermore, the carrier 1 further includes a fixing base 16 having a first mounting groove 161 and a second mounting groove 162, respectively, for fixing the first carrier block 11 and the second carrier block 12. In this embodiment, the fixing base 16 is used to fix the first carrier block 11 and the second carrier block 12, thereby ensuring that the first carrier block 11 and the second carrier block 12 do not shake or move during use, thereby improving the stability of the overall structure.

[0038] Furthermore, the first carrier block 11 is positioned within the first mounting groove 161, and the second carrier block 12 is provided with a mounting block 122 for plugging into the second mounting groove 162. The width of the first mounting groove 161 is equal to that of the first carrier block 11, and the shape of the second mounting groove 162 corresponds to the shape of the mounting block 122. In this embodiment, the first mounting groove 161 can provide a limiting effect on the first carrier block 11, ensuring its fixed position. Furthermore, the first mounting groove 161 can accommodate the first carrier block 11, thereby reducing occupied space. The plugging of the second mounting groove 162 with the mounting block 122 ensures that the second carrier block 12 is fixed in position.

[0039] Furthermore, the first pressing block 21 and the second pressing block 22 abut against each other; the first mounting slot 161 and the second mounting slot 162 communicate along the length of the watchband 3, allowing the first carrier block 11 to abut against the second carrier block 162. In this embodiment, the abutment between the first pressing block 21 and the second pressing block 22 allows the portion of the first pressing block 21 pressed against the watchband 3 to be connected with the portion of the second pressing block 22 pressed against the watchband 3, leaving no gap between the two pressed portions. This prevents friction between the first and second pressing blocks 21, 22 and the watchband 3, which could cause wrinkling or stretching deformation of the watchband 3 in the gap.

[0040] Furthermore, the first carrier block 11 and the second carrier block 12 are both screw-connected to the fixing base 16. In this embodiment, the screw connection ensures that the fixing base 16 firmly fixes the first carrier block 11 and the second carrier block 12, ensuring the stable positions of the first carrier block 11 and the second carrier block 12 and reducing the risk of displacement or loosening; the screw connection design is simple and convenient to install and disassemble, and is convenient for assembly, maintenance and replacement.

[0041] Furthermore, the second carrier block 12 is provided with a limiting structure 17, which is used to abut against the watchband 3 to limit its movement. In this embodiment, after the watchband 3 is placed on the carrier 1 and before the first and second pressure blocks 21 and 22 are pressed downward, the limiting structure 17 can initially limit the position of the watchband 3, preventing the watchband 3 from shifting, thereby ensuring the precise position of the watchband 3 after it is fixed. Specifically, the right end of the watchband 3 is provided with an assembly structure for the watch dial. The positioning of the limiting structure 17 at the right end of the watchband 3 ensures the accurate positioning of the assembly structure and improves the success rate of subsequent assembly of the watchband 3 with the watch dial.

[0042] Furthermore, the driving element is configured as a cylinder 4. In this embodiment, the cylinder 4 drives the first and second pressure blocks 21 and 22 downward. Cylinder 4 provides strong power output, ensuring that the first and second pressure blocks 21 and 22 securely secure the watchband 3. Furthermore, cylinder 4 has a simple structure and occupies a small space. It should be noted that the driving element includes, but is not limited to, the cylinder 4. In other embodiments, the driving element may also be a telescopic motor, an electric push rod, or the like.

[0043] The present invention also proposes an assembly device, which includes a strap 3 fixing mechanism. The specific structure of the strap 3 fixing mechanism refers to the above embodiment. Since the assembly device proposed by the present invention includes all schemes of all embodiments of the strap 3 fixing mechanism, it has at least the same technical effect as the strap 3 fixing mechanism, which will not be elaborated here one by one.

[0044] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
