Technical Field

[0001] This utility model relates to the field of watch manufacturing, specifically to a watch strap stretching detection device. Background Technology

[0002] A watch is a portable device used to tell time, typically worn on the wrist. It consists of a dial, case, strap, and movement. There are many types of watches, including quartz watches, mechanical watches, and smartwatches. Quartz watches use a quartz crystal oscillator to measure time, offering high accuracy; mechanical watches, on the other hand, use mechanical movement to drive the hands, featuring unique craftsmanship and design.

[0003] During the manufacturing process of watches, a tensile testing device is required to inspect the watch strap. However, current tensile testing devices cannot simultaneously perform torsion testing on the watch strap, thus affecting the inspection process. Utility Model Content

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] See Figures 1-5 In this embodiment of the present invention, a watch strap stretching detection device includes a support frame 1. Slide rails 5 are fixedly installed at the front and rear ends of the top of the support frame 1. A sliding frame 6 is connected to the slide rails 5. A first motor 7 is fixedly installed on the outer top wall of the support frame 1. A one-way screw 8 is installed on the motor shaft of the first motor 7. The end of the one-way screw 8 is connected to the inner wall of the support frame 1 through a bearing seat. The one-way screw 8 is threadedly connected to the sliding frame 6. When the first motor 7 operates, it drives the one-way screw 8 to rotate, causing the threaded sliding frame 6 to move and adjust its position on the slide rails 5, thus facilitating the adjustment of the sliding frame 6's position.

[0026] The sliding frame 6 is equipped with a telescopic rod 9 at its bottom. The telescopic part of the telescopic rod 9 is provided with a compression head 10. After the sliding frame 6 is adjusted to the specified position, the compression head 10 is driven to move downward by the telescopic rod 9. The compression head 10 moves downward and contacts the watch strap, thereby realizing the compression detection process of the watch strap.

[0027] A rotating rod 11 is rotatably mounted on one side wall of the support frame 1, and a first driving component for driving the rotating rod 11 to rotate is mounted on the outer wall of the support frame 1. Through the operation of the first driving component, the first driving component can drive the rotating rod 11 to adjust its rotational orientation.

[0028] The first drive assembly is fixedly connected to the outer wall of the support frame 1. The second motor 12 is provided with a drive gear 13 on the motor shaft of the second motor 12. A driven gear 14 is meshed on the drive gear 13. The driven gear 14 is connected to the rotating rod 11. Through the operation of the second motor 12, the second motor 12 drives the drive gear 13 to drive the meshed driven gear 14 to rotate. The driven gear 14 can drive the rotating rod 11 to adjust its rotational position.

[0029] A first clamping frame 15 is provided at the end of the rotating rod 11 located inside the support frame 1. A first elastic clamping component is provided at the top of the first clamping frame 15. The first elastic clamping component can achieve a tight clamping treatment on one end of the watch strap.

[0030] The first elastic clamping assembly includes a first recess 16 fixedly installed at both ends of the top of the first clamping frame 15. A first rotating shaft 17 is provided inside the first recess 16. The first rotating shaft 17 is connected to the first clamping claw 19 through a first torsion spring 18. By placing the watch strap on the first clamping frame 15 and manually rotating the first clamping claw 19, the first clamping claw 19 drives the first torsion spring 18 to rotate and generate torque. The torque drives the first clamping claw 19 to achieve a tight clamping process on the watch strap.

[0031] A movable rod 20 is slidably disposed on the other side wall of the support frame 1. A second clamping frame 21 is disposed at the end of the movable rod 20 located inside the support frame 1. A second elastic clamping component is disposed on the second clamping frame 21. A rack plate 26 is disposed at the bottom of the second clamping frame 21. A second driving component for driving the rack plate 26 to rotate is installed on the inner wall of the support frame 1. The rack plate 26 is driven to move by the second driving component. The rack plate 26 drives the second clamping frame 21 to move. The elastic clamping component disposed on the second clamping frame 21 realizes the clamping and stretching detection process for the other end of the watch strap.

[0032] The second elastic clamping assembly includes a second recess 22 fixedly installed at both ends of the top of the second clamping frame 21. A second rotating shaft 23 is provided inside the second recess 22. The second rotating shaft 23 is connected to the second clamping claw 25 through a second torsion spring 24. By manually rotating the second clamping claw 25 to move outward, the second torsion spring 24 rotates to generate torque. By placing the end of the watch strap on the second clamping frame 21, the torque pushes the second clamping claw 25 to clamp the watch strap tightly, thereby facilitating the stretch detection of the watch strap.

[0033] The second drive assembly includes a pair of fixed blocks 27 fixedly installed on the inner wall of the support frame 1. A third motor 28 is fixedly installed on the fixed blocks 27. A third rotating shaft 29 is installed on the motor shaft of the third motor 28. A drive gear 30 is installed on the third rotating shaft 29. The drive gear 30 is meshed with the rack plate 26. When the third motor 28 works, the third motor 28 drives the third rotating shaft 29 to rotate. The third rotating shaft 29 drives the meshed drive gear 30 to rotate. The drive gear 30 can realize the adjustment of the position of the rack plate 26.

[0034] Example 2

[0035] In another embodiment of this utility model, the difference between this embodiment and the above embodiment is that support legs 2 are fixedly provided at the four bottom corners of the support frame 1, and rollers 3 are provided at the bottom of the support legs 2. A brake 4 is provided at the outer end of the rollers 3. The rollers 3 can facilitate the adjustment of the movement position of the equipment, and the brake 4 can brake the rollers 3, thereby facilitating the use of the detection device.

[0036] The working principle of this utility model is as follows: One end of the watch strap is placed on the first clamping bracket 15. Manually rotating the first clamping jaw 19 causes the first torsion spring 18 to rotate, generating torque. This torque forces the first clamping jaw 19 to tightly clamp the watch strap. Manually rotating the second clamping jaw 25 causes the second rotating shaft 23 to rotate the second torsion spring 24, generating torque. This torque then causes the second clamping jaw 25 to tightly clamp the other end of the watch strap. A third motor 28 drives the third rotating shaft 29 to rotate, which in turn drives the drive gear 30 to rotate. The drive gear 30 then moves the meshing rack plate 26, which synchronously moves the rack plate 26. The second clamping claw 25 moves under the guidance of the moving rod 20, thereby enabling the stretching test of the watch strap. The first motor 7 drives the one-way screw 8 to rotate, which in turn drives the threaded sliding frame 6 to move. The sliding frame 6 synchronously drives the telescopic rod 9 to move, which in turn drives the extrusion head 10 to move downward to perform the extrusion test of the watch strap. In conjunction with the second motor 12, the driving gear 13 rotates, which in turn drives the meshing driven gear 14 to rotate. The driven gear 14 drives the rotating rod 11 to rotate, which in turn drives the first clamping frame 15 and the clamped watch strap to rotate, thereby enabling the torque test of the watch strap and facilitating the inspection and processing of the watch strap.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
