Description

Technical Field

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

[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 types of rolling suitcases. Some bags and luggage are equipped with wheels to help users carry them. During the production of bags and luggage, the wheels installed on the bags need to undergo abrasion resistance testing.

[0003] For example, an abrasion resistance testing device for luggage wheels, with authorization announcement number "CN220339954U", uses a hydraulic cylinder to drive a sliding block and its top test wheel to adjust their lateral position through the arrangement of components on the top side of the base. Simultaneously, a drive motor rotates the test wheel, causing it to rub against the luggage wheel. The actual travel distance of the luggage wheel is calculated based on the number of rotations of the test wheel, thus facilitating the calculation of the luggage wheel's abrasion resistance. However, when the luggage wheel is placed on the support pillar, the varying widths of the luggage wheels result in different contact areas between the luggage wheel and the test wheel, reducing the device's operational quality. Furthermore, after the luggage wheel is placed on the support pillar, the test wheel rotates during testing, causing the wheel to move on the support pillar, which reduces the testing effectiveness and further lowers the overall operational quality of the abrasion resistance testing device. Utility Model Content

[0004] The purpose of this invention is to solve the problems that when bag wheels are placed on a support column, the contact area between the bag wheels and the test wheel varies due to the different widths of the bags wheels. This reduces the working quality of the abrasion resistance testing device. Furthermore, when the bag wheels are placed on the support column, the test wheel rotates the bag wheels and moves them on the support column, leading to a decrease in the testing effect and further reducing the working quality of the abrasion resistance testing device. Therefore, this invention proposes an abrasion resistance testing device for bag wheels.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a wear resistance testing device for luggage wheels, comprising a main body, the inner wall of which is fixedly connected to a support column, a luggage wheel lifting mechanism inside the support column, the surface of the support column being sleeved with a pressure plate, a pressure plate fixing mechanism inside the pressure plate, the inner wall of the main body being fixedly connected to a motor via a bracket, the output shaft of the motor being fixedly connected to a rotating rod, the outer wall of the rotating rod being sleeved with a test wheel, the outer wall of the test wheel being rotatably connected to a horizontal plate via a bearing, a rotation counter being installed on the inner wall of the main body, the outer wall of the test wheel being in contact with the outer wall of the luggage wheel, and the outer wall of the luggage wheel being rotatably connected to the support column via a bearing.

[0008] Preferably, the outer wall of the lifting plate is fixedly connected to two reinforcing ribs, and the outer walls of the two reinforcing ribs are fixedly connected to the support plate.

[0009] Preferably, the pressure plate fixing mechanism includes a knob, the outer wall of which is rotatably connected to the pressure plate via a bearing, the outer wall of which is fixedly connected to a third gear, the outer wall of which is meshed with a fourth gear, the outer walls of which are respectively rotatably connected to two incomplete gears via belts, the outer walls of which are respectively meshed with two racks, the outer walls of which are sleeved with limiting rods, the outer walls of which are wound with springs, one end of which is fixedly connected to the racks, and the outer walls of which are both abutted against the support column.

[0010] Preferably, the outer wall of the third gear is rotatably connected to the pressure plate via a pin, and the outer wall of the fourth gear is rotatably connected to the pressure plate via a pin.

One end of the rack abuts against the support column. In this way, the movement of the bag wheels during testing can be avoided, which also improves the working quality of the wear resistance testing device. Attached Figure Description

[0025] Working principle:

[0026] When using the abrasion resistance testing device for the wheels of this bag:

[0027] Installation phase:

[0028] First, the operator places the test wheel 11 onto the rotating rod 10, then places the luggage wheel 8 onto the support column 2 and positions it on the support plate 5. Next, the operator rotates the handle 301, which drives the first connecting rod 302 to rotate. The first connecting rod 302 drives the first gear 303 to rotate, which in turn drives the second gear 304 to rotate. The second gear 304 then drives the roller 305 to rotate. The roller 305 moves the slider 306 via a surface groove. The slider 306 moves the second connecting rod 307, which in turn moves the lifting plate 308. The lifting plate 308 moves the reinforcing rib 4, which in turn moves the support plate 5. The support plate 5 then moves the luggage wheel 8 to the appropriate position. After the surface of the pressure plate 6 is in complete contact with the surface of the test wheel 11, the operator stops rotating the handle 301. Then the operator puts the pressure plate 6 on the support column 2 and makes the lower surface of the pressure plate 6 tightly adhere to the test wheel 8. Then the operator rotates the knob 701. The knob 701 drives the three gears 702 to rotate. The third gear 702 drives the fourth gear 703 to rotate. The third gear 702 and the fourth gear 703 drive the two incomplete gears 704 to rotate respectively. The two incomplete gears 704 rotate in opposite directions. The incomplete gears 704 drive the rack 705 to move. While the rack 705 moves on the limit rod 706, it drives the spring 707 to extend. After one end of the rack 705 presses against the support column 2, the operator stops rotating the knob 701.

[0029] Abrasion resistance testing stage:

[0030] Connect the external power supply to motor 9 and start motor 9. Motor 9 drives rotating rod 10 to rotate, rotating rod 10 drives test wheel 11 to rotate, and test wheel 11 drives bag wheel 8 to rotate. At the same time, connect the external power supply to the rotation counter 13 and start the rotation counter 13. The rotation counter 13 counts the number of rotations of test wheel 11 (i.e. bag wheel). The wear resistance performance of bag wheel 8 is calculated by the number of rotations of test wheel 11. This completes the wear resistance test of bag wheel.
