Description

Technical Field

[0001] This utility model relates to the field of luggage wheel testing technology, and in particular to a wear resistance testing device for luggage wheels. Background Art

[0002] Bags and luggage are a general term for all kinds of bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags, and various trolley cases. When producing bags and luggage with wheels, wear resistance tests are required on the wheels. This data is used to determine the wear resistance of the wheels and to identify quality issues related to the wheels.

[0003] Existing abrasion resistance testing devices for bags and luggage wheels have the following drawbacks: when testers conduct abrasion resistance tests on the wheels, most of them have relatively simple testing functions, which limits the scope of application of the testing devices. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a highly practical and simple-to-operate abrasion resistance testing device for bag wheels. This solves the problem mentioned in the background art that when testers conduct abrasion resistance tests on wheels, most of the testing functions are relatively simple, resulting in a limited range of applications for the testing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear resistance testing device for luggage wheels, comprising a working plate, a groove formed in the middle of the top surface of the working plate, a threaded rod rotatably connected to one side of the inner wall of the groove, a sliding block threaded through the surface of the threaded rod, an insert rod fixedly connected to the top of the sliding block, a connecting rod fixedly connected to one side of the sliding block, a pressure measuring component threaded through the middle of the top surface of the connecting rod, a support rod fixedly connected to the other side of the working plate, a servo motor fixedly connected to one side of the bottom of the support rod, a transmission rod fixedly connected to the output end of the servo motor, and a test wheel provided at one end of the transmission rod.

[0006] Optionally, the pressure measuring assembly includes a connecting rod with a screw threadedly connected to the top surface, and one end of the screw is rotatably connected to a pressing plate via a bearing.

[0007] Optionally, the bottom of the test wheel is snapped with a base, and the bottom of the base is threaded to the top surface of the work plate.

[0008] Optionally, a vertical rod is fixedly connected to one side of the working plate, and a positioning block is rotatably connected to the top of the vertical rod.

[0009] Optionally, the surface thread of the positioning block passes through a limit bolt, and the other end of the threaded rod is fixedly connected to a protrusion, and a hole adapted to the limit bolt is opened in the middle of the surface of the protrusion.

[0010] Optionally, the top surface of the test wheel is threaded with a screw, and the surface of the screw is threaded with a connecting piece.

[0011] This utility model provides a wear resistance testing device for bag wheels, which has the following beneficial effects:

[0012] 1. The abrasion resistance testing device for bag wheels, through the setting of pressure testing components and insertion rods, allows the tester to insert the wheel to be tested onto the surface of the insertion rod when the tester needs to test the wheel's pressure resistance. Then, the tester turns the screw to move the pressing plate downward, so that the pressing plate applies pressure to the test wheel, thus facilitating the tester to test the wheel's pressure resistance.

[0013] 2. The abrasion resistance testing device for bag wheels, through the setting of servo motor, sliding block and test wheel, allows the tester to turn the threaded rod to drive the sliding block to move along the slide groove towards the test wheel side when testing the abrasion resistance of the wheel, so that the wheel and the test wheel are in contact. Then, the positioning block is rotated and the limit bolt is turned to limit the protrusion. Then, the tester turns on the power of the servo motor, and its transmission rod drives the test wheel to rotate slowly, so that the tester can quickly test the abrasion resistance of the wheel.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a wear resistance testing device for bag wheels, including a working plate 1, a groove is provided in the middle of the top surface of the working plate 1, a threaded rod 2 is rotatably connected to one side of the inner wall of the groove, a sliding block 3 is threaded through the surface of the threaded rod 2, an insert rod 4 is fixedly connected to the top of the sliding block 3, a connecting rod 5 is fixedly connected to one side of the sliding block 3, a limit bolt 13 is threaded through the surface of the positioning block 12, a protrusion 15 is fixedly connected to the other end of the threaded rod 2, and a hole adapted to the limit bolt 13 is provided in the middle of the surface of the protrusion 15, a vertical rod 11 is fixedly connected to one side of the working plate 1, and a positioning block 12 is rotatably connected to the top of the vertical rod 11;

[0021] With the setting of threaded rod 2, limit bolt 13 and sliding block 3, when the tester adjusts the position of sliding block 3, the threaded rod 2 can be turned to drive sliding block 3 to slide along the slide groove, so that sliding block 3 drives the wheel to fit with the test wheel 10, so that the tester can adjust the position of the wheel.

[0022] Please see Figure 2 A support rod 7 is fixedly connected to the other side of the work plate 1. A servo motor 8 is fixedly connected to one side of the bottom of the support rod 7. A transmission rod 9 is fixedly connected to the output end of the servo motor 8. A test wheel 10 is provided at one end of the transmission rod 9. A base 14 is snapped into the bottom of the test wheel 10. The bottom of the base 14 is threaded to the top surface of the work plate 1.

[0023] With the servo motor 8, sliding block 3 and test wheel 10 set up, when the tester is testing the wear resistance of the test wheel, the threaded rod 2 can be turned to drive the sliding block 3 to move along the groove towards the test wheel 10 so that the wheel fits into the test wheel 10. The positioning block 12 is rotated and the limit bolt 13 is turned to limit the protrusion 15. Then the tester turns on the power of the servo motor 8, and its transmission rod 9 drives the test wheel 10 to rotate slowly, so that the tester can quickly test the wear resistance of the wheel.

[0024] Please see Figure 2 The top surface of the test wheel 10 is threaded with a screw, and the surface of the screw is threaded with a connecting piece.

[0025] The screws and connecting pieces facilitate the replacement of test wheel 10 by the test personnel.

The pressure measuring component 6 includes a screw 61 threadedly connected to the top surface of the connecting rod 5. One end of the screw 61 is rotatably connected to a pressing plate 62 via a bearing.

[0027] With the setting of pressure testing component 6 and insertion rod 4, when the tester needs to test the wheel's pressure resistance, the wheel to be tested can be inserted into the surface of insertion rod 4. Then, the tester can turn screw 61 to drive the pressing plate 62 to move downward, so that the pressing plate 62 can apply pressure to the test wheel, thus facilitating the tester to test the wheel's pressure resistance.

[0028] In this invention, the working steps of the device are as follows:

[0029] First step: First, the tester can insert the wheel into the surface of the insert rod 4. The threaded rod 2 can be turned to drive the sliding block 3 to move along the groove towards the test wheel 10 so that the wheel fits into the test wheel 10. Then, the positioning block 12 is rotated and the limiting bolt 13 is turned to limit the protrusion 15.

[0030] The second step: Then the tester turns on the power to the servo motor 8, and its transmission rod 9 drives the test wheel 10 to rotate slowly, so that the tester can quickly test the wear resistance of the wheel.

[0031] Third step: Finally, when the tester needs to test the wheel's pressure resistance, the wheel to be tested can be inserted into the surface of the insertion rod 4. Then, the tester turns the screw 61 to move the pressing plate 62 downward, so that the pressing plate 62 applies pressure to the test wheel.
