[0001] The invention belongs to the field of watch strap testing, in particular to a watch strap testing device. Background Art

[0002] In the daily inspection work of watch leather strap manufacturing, it is necessary to test its bearing strength. At this time, a push-pull test machine is often used to test the tensile strength of watch leather straps. However, when testing samples on a push-pull test machine, it is necessary to test multiple positions of a sample. At this time, it is necessary to manually replace and adjust the fixture. The existing fixture only has a single test. After completing one test, the fixture needs to be replaced for testing, which leads to cumbersome operations during the test and low test efficiency. Summary of the invention

[0003] The purpose of the present invention is to improve the shortcomings of the prior art and provide a watch strap testing device that can perform multiple tests on the watch strap.

[0004] The technical solution is as follows:

[0005] The watch strap testing device includes a first clamp, which includes a supporting base, a first clamping block, a second clamping block, a driving member and a connecting seat. The first clamping block and the second clamping block are respectively provided with a first clamping position and a second clamping position on opposite sides thereof. The first clamping block and the second clamping block are both installed on the supporting base. The driving member cooperates with at least one of the first clamping block and the second clamping block. The supporting base is rotatably connected to the connecting seat.

[0006] In one embodiment, the first clamping position includes a first limiting groove, and the second clamping position includes a second limiting groove.

[0007] In one embodiment, the first limiting groove and the second limiting groove are 4 mm to 6 mm away from the outer end surface of the first clamping block and the second clamping block.

[0008] In one embodiment, the first clamp also includes a first movable pin, a first hole groove is opened on the first clamping position, the first hole groove is a blind hole, a second hole groove is opened on the second clamping position, the second hole groove is a through hole, the first hole groove and the second hole groove are opposite to each other, and the movable pin penetrates into the first hole groove and the second hole groove.

[0009] In one embodiment, the driving member cooperates with the first clamping block and the second clamping block at the same time.

[0010] In one embodiment, the driving member includes a screw rod having two sections of threads, and the first clamping block and the second clamping block are respectively provided with threaded holes, the spiral directions of the two sections of threads are opposite, and each section of threads cooperates with the first clamping block or the second clamping block.

[0011] In one of the embodiments, the screw rod is further provided with a screwing head, and the screwing head is provided with anti-slip grooves.

[0012] In one embodiment, the support base and the connecting seat are connected by a positioning pin; when the positioning pin is removed, the support base and the connecting seat can rotate ninety degrees relative to each other.

[0013] In one embodiment, it also includes a second clamp, which includes a third clamp block, a fourth clamp block and a second movable pin.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, the watch strap testing device includes a first clamp 10 and a second clamp 20, the first clamp 10 includes a supporting base 13, a first clamp block 11, a second clamp block 12, a driving member 14 and a connecting seat 15, a first clamping position 111 and a second clamping position 121 are respectively provided on opposite sides of the first clamp block 11 and the second clamp block 12, the first clamp block 11 and the second clamp block 12 are both installed on the supporting base 13, the driving member 14 cooperates with at least one of the first clamp block 11 and the second clamp block 12, and the supporting base 13 is rotatably connected to the connecting seat 15.

[0034] When the watch strap needs to be clamped, insert the watch strap between the first clamp block 11 and the second clamp block 12. Under the action of the driving member 14, the first clamp block 11 and the second clamp block 12 are relatively close to each other, and then the watch strap is clamped using the first clamping position 111 and the second clamping position 121. At this time, the tensile test can be started to complete the first step of the watch strap test. When the angle needs to be adjusted, rotate the support base 13 to complete the angle adjustment. At this time, the watch strap does not need to be removed and re-clamped, which is convenient for operation and saves steps.

[0035] In order to cover the driving member 14 and protect it from external interference, a cover is provided on the base.

[0036] like Figure 2 As shown, the first clamping position 111 includes a first limiting groove 1112, and the second clamping position 121 includes a second limiting groove 1212. The first limiting groove 1112 and the second limiting groove 1212 are used to place the shaft hole end of the watch strap, meeting the national test standards for watch straps. In addition, the first limiting groove 1112 and the second limiting groove 1212 can accommodate the protruding structure of the shaft hole end, thereby ensuring the clamping force of the first clamping position 111 and the second clamping position 121 on the watch strap.

[0037] The first limiting groove 1112 and the second limiting groove 1212 are 4 mm to 6 mm away from the outer end surface of the second clamping block 12 of the first clamping block 11. Specifically, in this embodiment, the distance is set to 5 mm.

[0038] like Figure 2 As shown, the first clamp 10 also includes a first movable pin 16, a first hole slot 1111 is provided on the first clamping position 111, and the first hole slot 1111 is a blind hole, a second hole slot 1211 is provided on the second clamping position 121, and the second hole slot 1211 is a through hole, the first hole slot 1111 and the second hole slot 1211 are opposite, and the movable pin penetrates the first hole slot 1111 and the second hole slot 1211. At this time, when the first movable pin 16 penetrates into the first hole slot 1111 and the second hole slot 1211, it is perpendicular to the first clamping position 111 and the second clamping position 121, and the first movable pin 16 can be used to pass through the axial hole position of the watchband, and the reserved position size is adjusted by moving the first clamping block 11 and the second clamping block 12. Moreover, the first hole slot 1111 is a blind hole to prevent the first movable pin 16 from falling off.

[0039] like Figures 2 to 4 As shown, the driving member 14 cooperates with the first clamping block 11 and the second clamping block 12 at the same time. Driven by the driving member 14, the first clamping block 11 and the second clamping block 12 move relatively at the same time, so it is easier to maintain stability.

[0040] like Figures 2 to 4 As shown, the driving member 14 includes a screw rod 141, and the screw rod 141 is provided with two sections of threads. The first clamping block 11 and the second clamping block 12 are respectively provided with threaded holes. The spiral directions of the two sections of threads are opposite, and each section of threads cooperates with the first clamping block 11 or the second clamping block 12. Since the spiral directions of the threads at both ends are opposite, when the screw rod 141 is rotated, the movement directions of the first clamping block 11 and the second clamping block 12 are opposite, and there are two situations. The first situation is that the first clamping block 11 and the second clamping block 12 move away from each other at the same time, and the second situation is that the first clamping block 11 and the second clamping block 12 move close to each other at the same time.

[0041] In other embodiments, the threaded holes on the first clamping block 11 and the second clamping block 12 are arranged in opposite directions, and the two thread sections of the screw rod 141 are the same, or are the same thread section.

[0042] like Figure 3 As shown, the screw rod 141 is further provided with a screw head 142 , and the screw head 142 is provided with anti-slip grooves. The screw head 142 is used to manually control the rotation of the screw rod 141 .

[0043] like Figures 2 to 3As shown, the support base 13 and the connecting seat 15 are connected by a positioning pin 17; when the positioning pin 17 is removed, the support base 13 and the connecting seat 15 can be relatively rotated 90 degrees. At this time, the support base 13 and the connecting seat 15 are fixed by the positioning pin 17. When the direction needs to be adjusted, the positioning pin 17 is pulled out, and then the support base 13 is rotated to a predetermined 90 degrees or other angle, and then the positioning pin 17 is inserted to fix it.

[0044] like Figure 5 and Figure 6 As shown, the second clamp 20 comprises a third clamp block 21, a fourth clamp block 22 and a second movable pin 23. The third clamp block 21 is provided with a third hole slot 211, and the fourth clamp block 22 is provided with a fourth hole slot 221. The third hole slot 211 is a blind hole, and the fourth hole slot 221 is a through hole. The third hole slot 211 and the fourth hole slot 221 are opposite to each other, and the second movable pin 23 penetrates the third hole slot 211 and the fourth hole slot 221. The second clamp 20 is used for fixing the punching hole. The second movable pin 23 is moved in and out of the punching position to fix the punching hole of the watchband for detection. Moreover, it can be released by pulling out the second movable pin 23 upwards, which is more convenient.

[0045] Since there is a tail portion at the punching position of the watchband, a through avoidance groove 212 is provided on the clamping surface of the third clamping block 21. The tail portion of the watchband passes through the avoidance groove 212.

[0046] like Figure 6 As shown, a nail body 24 is provided on the third clamp block 21 and the fourth clamp block 22, and the nail body 24 cooperates with the third clamp block 21 and the fourth clamp block 22. By rotating the nail body 24, the third clamp block 21 is moved upward and the position between the third clamp block 21 and the fourth clamp block 22 is adjusted.

[0047] When quoting drawing descriptions, new features that appear are described; in order to avoid repeated quotations of drawings resulting in less concise descriptions, features that have been described clearly will not be quoted in the drawings one by one.

[0048] The purpose of the above embodiments is to exemplarily reproduce and deduce the technical solution of the present invention, and to fully describe the technical solution, purpose and effect of the present invention. Its purpose is to make the public understand the disclosed content of the present invention more thoroughly and comprehensively, and it does not limit the scope of protection of the present invention.

[0049] The above embodiments are not exhaustive enumerations of the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
