[0002] A bag wheel abrasion tester is a device specifically designed to test the abrasion resistance of bag wheels. It is typically used to test the durability and degree of wear of wheels when in contact with the ground during use. By simulating the rolling conditions of wheels in actual use, it helps manufacturers evaluate and improve wheel quality and lifespan. The basic principle of this testing equipment is to simulate the rolling state of bags during normal use through mechanical devices; the friction between the wheel and the ground leads to a certain degree of wear. Through long-term simulated testing, the abrasion resistance of the wheels can be evaluated, thus providing data support for product improvement.

[0003] Currently, there are various testing devices available on the market for the abrasion resistance of luggage wheels. Traditional testing methods typically involve manual operation to simulate wheel usage under different road surfaces and slopes. However, these methods often suffer from inaccurate simulation of the environment, unrealistic test results, and low efficiency. Especially when conducting abrasion resistance tests on luggage wheels, it is often impossible to accurately simulate the wheel's performance under various slope conditions, resulting in incomplete test results that fail to fully reflect the wheel's performance in actual use. Therefore, those skilled in the art have proposed a luggage wheel abrasion resistance testing machine to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bag wheel abrasion resistance testing machine, which aims to improve the problem that traditional testing methods generally simulate the use of wheels on different road surfaces and slopes through manual operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A bag wheel abrasion resistance testing machine includes a base, an internally rotatably connected mounting frame, an internally mounted conveyor belt, and a fixed support frame on both the front and rear sides of the top of the base. A fixing block is fixedly connected to the external side of the rear support frame, and a connecting block is rotatably connected to the external side of the fixing block. A lifting assembly is provided inside the base for lifting the mounting frame, and a snap-fit ​​assembly is provided inside the fixing block for fixing the fixing block and the connecting block.

A spring is sleeved on the outside of the pull rope. A knob is rotatably connected inside the fixing block, and locking slots are opened on both the left and right sides inside the connecting block.

[0009] Furthermore, the top end of the abutment plate abuts against the bottom end of the mounting frame, and the telescopic end of the telescopic rod is rotatably connected to the bottom end of the abutment plate.

[0010] Furthermore, the outer side of the limiting block is slidably connected to the inner side of the limiting groove.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 and Figure 2An embodiment of this utility model provides a bag wheel abrasion resistance testing machine, including a base 1, a mounting frame 2 rotatably connected inside the base 1, a conveyor belt 3 installed inside the mounting frame 2, support frames 4 fixedly connected to the front and rear sides of the top of the base 1, a fixing block 5 fixedly connected to the outside of the rear support frame 4, a connecting block 6 rotatably connected to the outside of the fixing block 5, a bag body 7 placed outside the conveyor belt 3, multiple baffles fixedly connected to the outside of the conveyor belt 3, and the handle of the bag body 7 placed between the fixing block 5 and the connecting block 6.

[0027] Specifically, base 1 serves as the support platform for the entire testing machine, constructed from robust materials to ensure stability during testing. Mounting frame 2 is rotatably connected to the interior of base 1, allowing it to rotate and thus enabling the conveyor belt 3 to be adjusted at different angles. This rotational function of mounting frame 2 allows the conveyor belt 3 to effectively simulate different angles and movement patterns of the bag wheels contacting the ground during testing. The conveyor belt 3 is a core component of this invention, used to support and move the bag body 7. Installed inside mounting frame 2, the conveyor belt 3 is driven by a motor to move back and forth, simulating the process of the bag wheels walking on the ground. Multiple baffles are fixedly connected to the outside of the conveyor belt 3; the main function of these baffles is to simulate uneven ground. In the test section, the wear resistance of the wheels of the bag body 7 was tested. The fixing block 5 was installed on the outside of the rear support frame 4 to limit the bag body 7. The fixing block 5 provided a stable support point, so that the bag body 7 would not be transported away with the conveyor belt 3, thus ensuring the accuracy of the test results. The connecting block 6 was connected to the fixing block 5 by rotation, providing a flexible adjustment method, so that the handle of the bag body 7 could be limited between the fixing block 5 and the connecting block 6. The bag body 7 is the main body of the test. By placing the handle part between the fixing block 5 and the connecting block 6, it ensures that the bag wheels are in contact with the conveyor belt 3 during the test. The friction and contact process between the wheels of the bag body 7 and the conveyor belt 3 simulates the wear situation in actual use, thus providing a realistic environment for the test.

[0028] Reference Figures 1-3 The base 1 is equipped with a lifting assembly 8, which is used to lift the mounting frame 2. The lifting assembly 8 includes a hydraulic cylinder 801, which is fixedly connected inside the base 1. The output end of the hydraulic cylinder 801 is rotatably connected to a stop plate 802. The top end of the stop plate 802 abuts against the bottom end of the mounting frame 2. Telescopic rods 803 are fixedly connected to the left and right sides inside the base 1. The telescopic ends of the telescopic rods 803 are rotatably connected to the bottom end of the stop plate 802. Limiting blocks 804 are fixedly connected to the left and right sides outside the mounting frame 2. Limiting grooves 805 are opened on the left and right sides inside the base 1. The outside of the limiting blocks 804 is slidably connected to the inside of the limiting grooves 805.

[0029] Specifically, a lifting assembly 8 is installed inside the base 1 to adjust the height of the mounting frame 2, allowing the conveyor belt 3 to be angled and simulate different road slopes. A hydraulic cylinder 801 is fixedly connected inside the base 1 and adjusts the position of the mounting frame 2 via hydraulic drive. The output end of the hydraulic cylinder 801 is connected to a stop plate 802. The hydraulic cylinder 801 achieves precise lifting and lowering movements through the pressure of hydraulic oil. The output end of the hydraulic cylinder 801 is rotatably connected to the stop plate 802, and the top of the stop plate contacts the bottom end of the mounting frame 2. As the hydraulic cylinder rises and falls, the stop plate 802 pushes the mounting frame 2 up and down, realizing the angle adjustment of the conveyor belt 3. The left and right sides inside the base 1... All components are fixedly connected with telescopic rods 803. The telescopic end of the telescopic rod 803 is rotatably connected to the bottom end of the support plate 802. The telescopic rod 803 has an adjustable length, which can adjust the supporting force and force direction of the support plate 802 during the lifting process, further enhancing the stability and accuracy of the lifting assembly 8. On the left and right sides of the outside of the mounting frame 2, limit blocks 804 are fixedly connected. Limit blocks 804 can cooperate with the limit grooves 805 opened on the left and right sides inside the base 1, thereby ensuring that the mounting frame 2 will not tilt or shift during the lifting process. The outside of the limit blocks 804 is slidably connected to the inside of the limit grooves 805, providing precise height control and preventing unstable movement of the mounting frame 2.

[0030] Reference Figure 2 , Figure 4 and Figure 5 The fixing block 5 has a buckle assembly 9 inside, which is used to fix the fixing block 5 and the connecting block 6. The buckle assembly 9 includes two mounting slots 901, which are respectively opened on the left and right sides inside the fixing block 5. The mounting slot 901 is slidably connected to the second limit block 903. One end of the second limit block 903 is fixedly connected to the locking block 904, and the other end of the second limit block 903 is fixedly connected to the pull rope 906. The pull rope 906 is fitted with a spring 902. One end of the spring 902 is fixedly connected to the inner wall of the mounting slot 901, and the other end of the spring 902 is fixedly connected to the outside of the second limit block 903. The fixing block 5 is rotatably connected to the knob 907. The adjacent side of the two pull ropes 906 is fixedly connected to the outside of the knob 907. The connecting block 6 has a locking groove 905 on both the left and right sides inside. The outside of the locking block 904 matches the inside of the locking groove 905.

[0031] Specifically, mounting grooves 901 are respectively opened on the left and right sides of the fixing block 5, which can accommodate the sliding of the second limiting block 903. The second limiting block 903 is installed inside the mounting groove 901 and can slide along the groove. The function of the second limiting block 903 is to cooperate with the locking block 904, and adjust the connection between the fixing block 5 and the connecting block 6 by pulling the rope 906. One end of the locking block 904 is fixedly connected to the second limiting block 903. By matching with the locking groove 905 opened inside the connecting block 6, a stable connection between the fixing block 5 and the connecting block 6 is achieved. One end of the pulling rope 906 is fixedly connected to the second limiting block 903. 3. The other end is operated by knob 907, which allows the pull rope 906 to drive the second limiting block 903 to slide along the mounting groove 901, thereby realizing the disassembly or connection of the fixing block 5 and the connecting block 6. The spring 902 is used to reset the limiting block 903, maintain the stability of the structure and the buckle function. Knob 907 is connected to pull rope 906. Rotating knob 907 can pull or release pull rope 906, thereby adjusting the movement of the second limiting block 903 and controlling the opening and closing of buckle assembly 9. The fixing block 5 is fixedly connected to the connecting block 6 through buckle assembly 9, ensuring the stability of the bag body 7 in the test.

[0032] Working principle: First, by starting the hydraulic cylinder 801, the bottom plate 802 is moved upward, which in turn moves the mounting frame 2, thus simulating the wear resistance of the wheels on the bag body 7 under different slopes.

[0033] Secondly, by rotating the knob 907, the two pull ropes 906 are moved to the same side, thereby causing the limiting block 903 to move as well, and then the locking block 904 to move as well, so that the locking block 904 disengages from the slot 905, thereby pulling the connecting block 6 to rotate outward, so that the handle of the bag body 7 can be conveniently placed between the fixing block 5 and the connecting block 6, and the wheels of the bag body 7 are placed on the conveyor belt 3, thereby rotating the connecting block 6 to move inward, and then through the elastic action of the spring 902, the limiting blocks 903 on both sides are moved outward, thereby causing the locking block 904 to move into the slot 905, so that the locking block 904 engages with the slot 905, thereby limiting the bag body 7;

[0034] Finally, by starting the conveyor belt 3, the wheels of the bag body 7 are subjected to a wear resistance test on the conveyor belt 3 in conjunction with the barrier plate.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
