Description

Technical Field

[0001] This utility model relates to the field of watch strap testing technology, specifically a watch strap tensile testing device. Background Technology

[0002] In the production and quality control of watch straps, tensile testing is a crucial step in ensuring product performance and user safety. Its core purpose is to assess the tensile strength, durability, and connection stability of the watch strap by simulating the tensile forces it might experience in daily use. This ensures that the strap will not break or detach under prolonged wear and intense pulling, thus preventing watch damage or user safety risks due to strap failure. Simultaneously, tensile test data provides important information for material selection and structural design optimization, helping companies improve product quality and market competitiveness.

[0003] Currently, watch strap tensile testing largely relies on manual operation. During testing, operators must manually place the watch strap between the clamps of the testing equipment, securing both ends with the clamps before starting the tensile test. However, during manual placement, factors such as operator technique, force control, or visual judgment errors can easily cause the watch strap to tilt. This tilt results in uneven distribution of tensile force at both ends of the strap, causing a deviation between the actual force direction and the preset axial tensile force during testing. Consequently, the test data becomes distorted and fails to accurately reflect the true tensile strength of the watch strap. If quality judgments are based on such inaccurate test results, substandard products may enter the market, or qualified products may be misjudged, affecting product quality reputation and increasing unnecessary production costs and safety hazards. To avoid watch strap tilting caused by manual operation and improve the accuracy and reliability of tensile test data, we propose a watch strap tensile testing device.

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.

[0018] Please see Figure 1-6 This utility model provides a technical solution: a watch strap tensile testing device, including a mounting base 1, a plurality of support feet 8 fixedly connected to the bottom of the mounting base 1, two base plates 9 slidably connected to the top of the mounting base 1, a mounting box 16 provided above the base plates 9, a limiting component for limiting the position of the watch strap installed on the mounting box 16, a clamping component for clamping the watch strap for tensile testing installed on the mounting base 1, and a driving component for driving the limiting component and the clamping component to operate on the mounting base 1; the limiting component includes a plurality of connecting frames 4, the connecting frames 4 are slidably installed on the top of the mounting box 16, a limiting claw 17 is fixedly installed on the connecting frames 4, and a sliding mechanism for sliding the connecting frames 4 is installed on the mounting box 16.

[0019] The sliding mechanism includes two sets of sliding plates 3. The sliding plates 3 are arranged above the connecting frame 4. A fixing block 37 is fixedly connected to the top of the connecting frame 4. Two sets of first sliding grooves matching the fixing block 37 are opened on the sliding plates 3. The fixing block 37 is slidably connected to the first sliding groove. An L-shaped plate 6 is fixedly connected to the end of the sliding plate 3 away from the connecting frame 4.

[0020] In use, the watch strap is placed between the limiting jaws 17. The drive assembly moves the L-shaped plate 6 towards the mounting box 16, causing the sliding plate 3 to move. With the cooperation of the fixing block 37 and the first sliding groove, the sliding plate 3 moves and causes the two sets of connecting brackets 4 to slide on the mounting box 16, so that the two sets of limiting jaws 17 move closer to each other until the watch strap is clamped between the two sets of limiting jaws 17. The limiting jaws 17 can initially limit the two ends of the watch strap, avoiding the watch strap tilting caused by manual operation, thereby improving the accuracy and reliability of the tensile test data. Then, the drive assembly drives the clamping assembly to operate, clamping the two ends of the watch strap and performing tensile test.

[0021] The clamping assembly includes several sets of clamping jaws 19, which are slidably mounted on the mounting box 16. A lifting rod 18 is fixedly connected to the side of the clamping jaws 19 closest to the mounting box 16. The mounting box 16 has a second sliding groove that matches the lifting rod 18. The lifting rod 18 is slidably connected to the second sliding groove. Anti-slip strips are provided on the sides of the two sets of clamping jaws 19 that are close to each other. A moving mechanism that drives the mounting box 16 to move is installed on the mounting base 1. A lifting mechanism that drives the clamping jaws 19 to rise and fall is installed on the mounting box 16.

[0022] The moving mechanism includes a bidirectional screw 12, which is rotatably mounted on the mounting base 1. A rotating disk 7 is fixedly connected to the right end of the bidirectional screw 12. A connecting rod 11 is fixedly connected to the bottom of the base plate 9. A third sliding groove matching the connecting rod 11 is provided on the mounting base 1. The connecting rod 11 is slidably connected to the third sliding groove. A connecting plate 13 is fixedly connected to the bottom of the connecting rod 11. The bidirectional screw 12 is threaded through the connecting plate 13.

[0023] The lifting mechanism includes several sets of rotating screws 36, which are rotatably mounted on the mounting box 16.

A rotating mechanism that drives the driven gear 21 to rotate is installed on the base plate 9.

[0024] The rotating mechanism includes two sets of rotating rods 24. The rotating rods 24 are rotatably mounted on the base plate 9. The bottom of the rotating rods 24 is fixedly connected to the driving gear 23, which meshes with the driven gear 21. The rotating rods 24 are rotatably mounted into the mounting box 16. The top of the rotating rods 24 is fixedly connected to the driven bevel gear 22. The mounting box 16 is rotatably mounted on a rotating cylinder 28. The rotating cylinder 28 is fixedly mounted on the outside of the rotating cylinder 28, and the driving bevel gear 25 meshes with the driven bevel gear 22.

[0025] The drive assembly drives the rotating cylinder 28 to rotate, which in turn drives the driving bevel gear 25 and the driven bevel gear 22 to rotate, which in turn drives the rotating rod 24 and the driving gear 23 to rotate. The driving gear 23 rotates, which drives the driven gear 21 to rotate, which in turn drives the rotating screw 36 to rotate. The rotating screw 36 rotates, which moves the lifting block 20 and the lifting rod 18, causing the two sets of clamping jaws 19 to come closer together and clamp the watch strap. Then, the rotating disk 7 is manually rotated, which drives the bidirectional screw 12 to rotate, which moves the connecting plate 13 and the connecting rod 11, causing the two sets of base plates 9 to move away from each other, so that the watch strap is continuously stretched for tension testing.

[0026] The drive assembly includes two sets of drive rods 26. The drive rods 26 slide through the rotating cylinder 28. A handle 2 is fixedly connected to the end of the drive rod 26 away from the rotating cylinder 28. An L-shaped plate 6 is rotatably sleeved on the drive rod 26. A fixing mechanism for fixing the position of the drive rod 26 is installed on the drive rod 26.

[0027] First, push the handle 2 towards the mounting box 16 to move the drive rod 26 and the L-shaped plate 6 until the watch strap is clamped between the two sets of limit claws 17. Fix the position of the drive rod 26 by the fixing mechanism so that it cannot move. Then, manually turn the handle 2 to drive the drive rod 26 to rotate, which in turn drives the rotating cylinder 28 to rotate.

[0028] The fixing mechanism includes two sets of pressing rods 10. The pressing rods 10 slide through the drive rod 26. A central rod 29 is fixedly connected to one end of the pressing rod 10 near the rotating cylinder 28. Several sets of connecting rods 30 are hinged to the central rod 29. A sliding block 31 is hinged to one end of the connecting rod 30 away from the central rod 29. Several sets of sliding openings 27 that match the sliding block 31 are opened on the drive rod 26. The sliding block 31 is slidably connected to the sliding opening 27. A limit block 38 is fixedly connected to the side of the sliding block 31 away from the central rod 29. Several sets of limit holes 34 that match the limit block 38 are opened on the rotating cylinder 28.

[0029] A connecting plate 32 is slidably connected to the inner wall of the drive rod 26. The end of the center rod 29 near the rotating cylinder 28 is fixedly connected to the connecting plate 32. A spring 33 is fixedly connected to the side of the connecting plate 32 away from the center rod 29. The end of the spring 33 away from the connecting plate 32 is fixedly connected to the drive rod 26.

[0030] Manually press the pressing rod 10 to move the central rod 29 closer to the rotating cylinder 28. The connecting rod 30 drives the sliding block 31 to slide on the sliding opening 27, causing the sliding block 31 to move closer to the central rod 29. This causes the limiting block 38 to disengage from the limiting hole 34. At this time, the driving rod 26 can be moved. After the driving rod 26 moves to the appropriate position, the pressing rod 10 is released. Under the elastic force of the spring 33, the central rod 29 and the pressing rod 10 are reset, so that the limiting block 38 is inserted into the limiting hole 34 again, thus fixing the position of the driving rod 26 and preventing it from moving.

[0031] Mounting base 1 is fixedly connected to the top of mounting cover 5, and a baffle cover 35 is fixedly connected to the left base plate 9. The baffle cover 35 slides through the mounting cover 5, and a baffle plate 15 is fixedly connected to the right base plate 9. The baffle plate 15 slides through the baffle cover 35.

[0032] The third groove on the mounting base 1 is blocked by the baffle 35 and the baffle plate 15 to prevent debris from entering the mounting base 1 when the watch strap breaks, thus affecting the operation of the subsequent instruments.

[0033] Working principle: In use, place the watch strap between the limiting jaws 17, manually press the pressing rod 10, which moves the center rod 29 towards the rotating cylinder 28. Through the connecting rod 30, the sliding block 31 slides on the sliding opening 27, causing the sliding block 31 to move closer to the center rod 29. This causes the limiting block 38 to disengage from the limiting hole 34, at which point the drive rod 26 can move. Then, push the handle 2 towards the mounting box 16, which moves the drive rod 26, the L-shaped plate 6, and the sliding plate 3. The sliding plate 3 then slides under the cooperation of the fixing block 37 and the first sliding groove. The movement of plate 3 causes the two sets of connecting brackets 4 to slide on the mounting box 16, bringing the two sets of limiting claws 17 closer together until the watch strap is clamped between the two sets of limiting claws 17. Then, the pressing rod 10 is released, and under the elastic force of the spring 33, the central rod 29 and the pressing rod 10 are reset, so that the limiting block 38 is inserted into the limiting hole 34 again, thus fixing the position of the driving rod 26 and preventing it from moving. The limiting claws 17 can initially limit the two ends of the watch strap, avoiding the watch strap tilting caused by manual operation, thereby improving the accuracy and reliability of the tensile test data. After the limit is completed, manually turn handle 2. Handle 2 drives drive rod 26 to rotate, which in turn drives rotating cylinder 28 to rotate. This drives drive bevel gear 25 and driven bevel gear 22 to rotate, which in turn drives rotating rod 24 and drive gear 23 to rotate. Drive gear 23 drives driven gear 21 to rotate, which in turn drives rotating screw 36 to rotate. Rotating screw 36 drives lifting block 20 and lifting rod 18 to move, causing two sets of clamping jaws 19 to come closer together and clamp the watch strap. Then, manually turn rotating disk 7 to drive bidirectional screw 12 to rotate, which drives connecting plate 13 and connecting rod 11 to move, causing two sets of base plates 9 to move away from each other, so that the watch strap is continuously stretched for tension testing.
