Description

Technical Field

[0001] The utility model relates to the technical field of tension and torque testing, in particular to a strap tension and torque testing machine. Background Art

[0002] Watch strap is a general term for the effective part of a watch that fixes the wrist. There are many kinds of watch strap materials. Cowhide is the most common one, while crocodile leather is the most precious one. Crocodile leather watch strap is also called the "platinum" of leather watch strap. In the production process of watch strap, it is necessary to test the tension and torque of the watch strap. When testing the tension and torque of the watch strap, it is necessary to use a watch strap tension and torque testing machine. Among them, the "watch strap tension and torque testing machine" disclosed in the application number "CN207764059U" has solved the problem that watches will be pulled and twisted when worn during actual use. Products are often sold without tension and twisting tests, causing a large number of after-sales problems. After further search, it was found that the application number "CN20 8537306U” discloses a “power cord pulling and torque testing machine”, which, through a specific technical structure setting, effectively solves the technical drawbacks of a relatively complex structure, inconvenient operation and use, and inconvenient recording of test results. However, in actual use, a watch strap pulling and torque testing machine with a similar structure still has many defects, such as: when the existing watch strap pulling and torque testing machine is testing the pulling and torque of the watch strap, it is not convenient to perform protection work, so that the watch strap is prone to breakage and splashing during the test, which is easy to cause harm to the staff. At the same time, it is not convenient to perform a buffering operation on the weight when it suddenly falls during the test, so that the weight is easy to fall and cause a collision, which is easy to cause the weight to bump and affect the accuracy of the test, so it is necessary to design a watch strap pulling and torque testing machine. Utility Model Content

[0003] The purpose of the utility model is to provide a watch strap tension and torque testing machine to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a watch strap tension and torque testing machine, comprising a body, a fixed cover and a fixed plate, a rotating frame is rotatably installed on the top of the body, a movable frame is slidably installed on the top of the body on one side of the rotating frame, a torque detector is fixedly installed on the inner side of the movable frame, a fixed cover is fixedly connected to the top of the body outside the movable frame, a movable cover is slidably installed on the inner side of the fixed cover, a first brush is fixedly installed on the top of the movable cover and the inner side of the fixed cover at the bottom, a cable extending out of the fixed cover is movably installed on one side of the movable frame, one end of the cable is movably connected to a weight, a fixed plate is fixedly installed on one side of the body at the bottom of the weight, a movable plate is movably installed on the top of the fixed plate, and a shock-absorbing pad is fixedly connected to the top of the movable plate.

[0005] By pulling the movable cover backward along the slide slot to flip it, the first brush can be used to clean both sides of the movable cover. By fixing the watch strap on the inner side of the rotating frame and the fixed frame, and pulling the movable cover forward to flip it, the test can be protected to avoid the watch strap breaking and splashing during the test to cause harm to the staff. The fixed cover and the movable cover are both made of hard transparent plastic, which can facilitate the observation of the test process. By hanging the weight on one end of the cable, the gravity of the weight is used to pull the cable to move the movable frame to the right, and the fixed frame is simultaneously driven to move to the right, which can facilitate the watch strap. The tensile force is tested by driving the rotating frame to rotate and synchronously driving the rotating frame to flip forward and backward. The torque of the watch strap can be tested in conjunction with the fixed frame. The torque of the watch strap during the test can be recorded by the torque tester. When the watch strap breaks during the test, it is easy to cause the movable frame to move to the right, causing the weight to fall suddenly. The shock-absorbing pad is used to dampen the falling weight. The movable plate can be pressed to move downward when falling, so that the falling weight can be buffered to avoid impact caused by the falling weight, which may cause the weight to collide and affect the accuracy of the test.

[0006] Preferably, the rotating frame and the machine body are movably mounted via a stepper motor, and the cable and the movable frame are movably connected via a fixing buckle. The stepper motor can drive the rotating frame to rotate, and the fixing buckle can conveniently connect and fix the cable and the movable frame.

[0007] Preferably, a fixed frame corresponding to the torque detector is fixedly installed on one side of the movable frame, and a test column is rotatably connected to the inner side of the fixed frame and the rotating frame. The fixed frame can conveniently support a group of test columns, and the test columns can conveniently test the tension and torque of the watch strap.

[0008] Preferably, a support frame is fixedly installed on the top of the machine body on one side of the movable frame, and a pulley corresponding to the cable is rotatably installed on one end of the support frame. The pulley can be supported by the support frame and synchronously rotated, and the cable can be rolled and supported by the pulley.

[0009] Preferably, a second brush corresponding to the fixed cover is fixedly installed at the bottom of the movable cover, and the movable cover and the fixed cover are slidably installed through a slide groove. The second brush can be used to clean the inner wall of the fixed cover, and the slide groove can facilitate the movable cover to flip.

[0010] Preferably, a fixed column penetrating the fixed plate is fixedly installed at the bottom of the movable plate, and a damping pad corresponding to the fixed column is fixedly installed on the inner side of the fixed plate. When the fixed column is driven downward by the movable plate, the damping pad on the inner side of the fixed plate can perform friction damping operation on the fixed column.

[0011] Preferably, a fixing groove is provided inside the shock-absorbing pad, and a buffer spring is fixedly installed between the movable plate and the fixed plate. The fixing groove can conveniently deform the shock-absorbing pad to perform a shock-absorbing operation on the weight, and can also conveniently restore the shock-absorbing pad, and the buffer spring can buffer the movable plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting the fixed cover, the movable cover, the first brush and the second brush to cooperate with each other, the movable cover can be pulled backward along the slide groove to flip the movable cover, the first brush can be used to clean both sides of the movable cover, and the second brush can be used to clean the inner wall of the fixed cover. By pulling the movable cover forward to flip the movable cover, the test can be protected to avoid the watch strap breaking and splashing during the test to cause harm to the staff. The fixed cover and the movable cover are both made of hard transparent plastic, which can facilitate the observation of the test process.

[0014] 2. By setting up the mutual cooperation between the fixed plate, the movable plate and the shock-absorbing pad, when the watch strap breaks during the test, it is easy to cause the movable frame to move to the right, causing the weight to fall suddenly. The shock-absorbing pad can be used to damp the falling weight. When falling, the movable plate can be pressed to move downward along the fixed plate. Friction damping is provided between the fixed column and the fixed plate, and the falling weight can be buffered by the buffer spring to avoid collision caused by the falling weight, which may affect the accuracy of the test.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Embodiment 1

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the strap tension and torque testing machine proposed by the utility model comprises a body 1, a fixed cover 3 and a fixed plate 5, a rotating frame 102 is rotatably installed on the top of the body 1, a movable frame 2 is slidably installed on the top of the body 1 on one side of the rotating frame 102, and a torque detector 201 is fixedly installed on the inner side of the movable frame 2;

[0025] A fixed cover 3 is fixedly connected to the top of the machine body 1 outside the movable frame 2, a movable cover 4 is slidably installed inside the fixed cover 3, a first brush 301 is fixedly installed on the top of the movable cover 4 and the inside of the fixed cover 3 at the bottom, a cable 204 extending from the fixed cover 3 is movably installed on one side of the movable frame 2, a weight 205 is movably connected to one end of the cable 204, a fixed plate 5 is fixedly installed on one side of the machine body 1 at the bottom of the weight 205, a movable plate 501 is movably installed on the top of the fixed plate 5, and a shock-absorbing pad 504 is fixedly connected to the top of the movable plate 501;

[0026] The rotating frame 102 and the body 1 are movably installed through the stepping motor 101, a fixed frame 202 corresponding to the torque tester 201 is fixedly installed on one side of the movable frame 2, and the fixed frame 202 is rotatably connected to the inner side of the rotating frame 102 with a test column 103, a second brush 401 corresponding to the fixed cover 3 is fixedly installed on the bottom of the movable cover 4, and the movable cover 4 and the fixed cover 3 are slidably installed through a slide groove 302, a fixed column 502 penetrating the fixed plate 5 is fixedly installed on the bottom of the movable plate 501, and a damping pad corresponding to the fixed column 502 is fixedly installed on the inner side of the fixed plate 5, a fixing groove 505 is opened inside the shock-absorbing pad 504, and a buffer spring 503 is fixedly installed between the movable plate 501 and the fixed plate 5.

[0027] The working principle of the strap tension and torque testing machine based on Example 1 is as follows: by pulling the movable cover 4 to flip backward along the slide slot 302, the second brush 401 is simultaneously driven to flip backward, the first brush 301 can be used to clean both sides of the movable cover 4, and the second brush 401 can be used to clean the inner wall of the fixed cover 3, by fixing the strap on the outside of the two groups of test columns 103, by pulling the movable cover 4 to flip forward, the test can be protected to avoid the strap breaking and splashing during the test to cause harm to the staff, the fixed cover 3 and the movable cover 4 are both made of hard transparent plastic material, which can facilitate the observation of the test process;

[0028] By hanging the weight 205 on one end of the cable 204, the weight 205 is used to pull the cable 204 to move the movable frame 2 to the right, and the fixed frame 202 is driven to move to the right synchronously, which can drive a group of test columns 103 to move to the right, so that the two groups of test columns 103 can be separated, which can facilitate the test of the tension of the watch strap.
