Description

Technical Field

[0001] The utility model relates to the technical field of luggage testing, in particular to a luggage wheel wear tester. Background Art

[0002] The luggage wheel wear tester is a device used to test the wear resistance of luggage or suitcase wheels. When testing luggage wheels, some devices can install the wheels separately on the device and perform friction tests on the wheels using friction rollers. In order to test the wear resistance of luggage wheels on bumpy roads, some devices will add bumps to the outer wall of the friction roller to simulate bumpy roads. At that time, these bumps were generally fixed to the friction roller by multiple sets of bolts. Disassembly was too troublesome, which reduced the efficiency of switching between different road surfaces and had low practicality.

[0003] Chinese Patent Publication No.: CN213779476U discloses a luggage wheel wear test device, including a base, wherein the left and right sides of the base are fixedly connected with brackets, the upper end face of the bracket is fixedly connected with a casing, the right end face of the casing is fixedly connected with a motor casing, a rotating motor is fixedly connected inside the motor casing, the front end of the rotating motor is rotatably connected with a transmission shaft, the other end of the transmission shaft is fixedly connected with a threaded rod, and the upper left and right sides of the casing are fixedly connected with a first fixed plate; in this utility model, the luggage wheel can be fixed in the clamping block by the arranged rotating motor and clamping block, and the threaded rod is driven to rotate by the operation of the rotating motor, and the moving block outside the threaded rod moves due to the rotation of the threaded rod, driving the luggage wheel to move, and the wear resistance of the luggage wheel can be effectively tested in conjunction with the test plate, which is very practical.

[0004] In the above technology, although the practicality of the wear-resistant testing equipment for luggage wheels can be improved through its designed structure, when testing different road surfaces, the test plate needs to be removed and replaced with other different types of test plates. The process is too troublesome and reduces work efficiency. Secondly, the clamping block for fixing the wheel is integrally formed, and the spacing cannot be adjusted. It cannot adapt to luggage wheels of different thicknesses and has low applicability. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3The utility model provides an embodiment: a luggage wheel wear tester, comprising a wear tester 1, a bracket 3 is arranged at the top of the wear tester 1, a test roller 2 is arranged on the front surface of the wear tester 1, a fixing component 5 is arranged on the lower surface of the bracket 3, and a switching road surface component 4 is arranged on the inner wall of the test roller 2;

[0033] The switching road surface component 4 includes an adjusting block 41. The arc-shaped surface of the right surface of the adjusting block 41 can be consistent with the amplitude of the outer wall of the test roller 2 when closed to ensure the accuracy of the test. The adjusting block 41 is slidably connected to the right surface of the test roller 2. A groove 49 is arranged on the inner wall of the top of the adjusting block 41. A rotating rod 48 is rotatably connected to the inner wall of the groove 49. A guide plate 46 is fixedly connected to the outer wall of the rotating rod 48. The guide plate 46 is unfolded and contacts the outer wall of the test roller 2. There will be a certain inclination to avoid collision between the wheel and the adjusting block 41. A torsion spring 47 is sleeved on the outer wall of the front end of the rotating rod 48. The torsion spring 47 itself has a certain elasticity. Through its own elasticity, the guide plate 46 is always kept in a horizontal state, ensuring that the guide plate 46 can be closely attached to the outer wall of the test roller 2 when in use, and can also be quickly reset when retracted, thereby improving convenience. One end of the torsion spring 47 is fixedly connected to the inner wall of the groove 49, and the other end of the torsion spring 47 is fixedly connected to the right end of the front surface of the guide plate 46.

[0034] Reference Figure 1 , Figure 4 The fixing assembly 5 includes a fixing shell 51, which is fixedly connected to the lower surface of the bracket 3. A bidirectional threaded rod 53 is rotatably connected to the front surface of the fixing shell 51. The bidirectional threaded rod 53 is a prior art, and its outer wall is provided with two groups of threads with different rotation directions, and the two groups of threaded outer walls are respectively connected to a group of clamping blocks 52. When the bidirectional threaded rod 53 rotates, it will drive multiple groups of clamping blocks 52 to move in relative or opposite directions, so as to fix wheels of different thicknesses. The outer wall of the bidirectional threaded rod 53 is threadedly connected with the clamping block 52. The bidirectional threaded rod 53 has the characteristics of front and rear self-locking, which ensures self-rotation and the stability of the connection. The top of the clamping block 52 is slidably connected to the inner wall of the fixing shell 51.

[0035] Referring to the figure, a through groove 6 is provided at the right end of the front surface of the test roller 2, and a T-shaped slider 45 is slidably connected to the inner wall of the through groove 6. The rear surface of the T-shaped slider 45 is fixedly connected to the left end of the front surface of the adjusting block 41. A round rod 44 is slidably connected to the front surface of the T-shaped slider 45, and a connecting plate 42 is fixedly connected to the front surface of the round rod 44. A spring 43 is sleeved on the outer wall of the round rod 44. The spring 43 always pushes the round rod 44 to move backward through the connecting plate 42 due to its own elasticity to ensure the stability of the limit. One end of the spring 43 is fixedly connected to the front surface of the T-shaped slider 45, and the other end of the round rod 44 is fixedly connected to the rear surface of the connecting plate 42. A groove 2 7 is provided on the lower side of the front surface of the test roller 2 adjacent to the through groove 6, and the rear surface of the round rod 44 contacts the inner wall of the groove 2 7. The left surface of the guide plate 46 is set as an inclined surface. The inclined surface prevents the wheel from colliding with the side of the guide plate 46, thereby reducing the hardness test result of the wheel being damaged.

[0036] Referring to the figure, a threaded hole 8 is provided at the bottom end of the front surface of the clamping block 52, and a circular ring 54 is rotatably connected to the bottom end of the front surface of the clamping block 52. A rubber ring 55 is fixedly connected to the front surface of the circular ring 54. Specifically, the center of the circular ring 54 and the threaded hole 8 are on the same horizontal line, and the rubber ring 55 is made of rubber material. The rubber material can ensure that when the rubber ring 55 clamps the wheel, the wheel will not be damaged, and the stability of the clamping can also be increased.

[0037] Working principle: When in use, when the wheel needs to be installed, it is only necessary to put the wheel between the multiple groups of clamps 52, and align the rotating shaft hole of the wheel with the threaded hole 8, and then rotate the two-way threaded rod 53. At this time, the multiple groups of clamps 52 will move relatively to clamp the wheel. When the rubber ring 55 contacts the wheel, it will deform, which can prevent the wheel from being damaged and make the clamping more stable. At this time, the stud bolts can be passed through the rotating shaft hole and the threaded hole 8 of the wheel, and then tightened with threads to prevent the wheel from falling off. The above structure can be used to fix wheels of different thicknesses, which is quick and convenient. At the same time, when testing the wheel, the wheel will rotate with the test roller 2 and the ring 54 will also rotate accordingly, ensuring the stability of the wheel rotation and preventing the wheel from tilting or offset.

[0038] When it is necessary to test the wheels on different ground surfaces, it is only necessary to pull the connecting plate 42 forward, which will drive the round rod 44 to move forward and stretch the spring 43 until the round rod 44 is completely out of the inner wall of the groove 2 7. At this time, the T-shaped slider 45 can be pushed, and the T-shaped slider 45 will drive the adjusting block 41 and the guide plate 46 to move until the guide plate 46 is completely removed from the inner wall of the test roller 2. At this time, the guide plate 46 is pulled to reverse, and the guide plate 46 will deform the torsion spring 47. At this time, the adjusting block 41 is pushed in the reverse direction to make the guide plate 46 contact the outer wall of the test roller 2, so that the guide plate 46 will form an inclined surface to prevent the roller from colliding during the test. The adjusting block 41 can also be pushed in the reverse direction to achieve the purpose of adjusting the bumpiness of the test, thereby improving practicality. After the adjustment is completed, the connecting plate 42 can be loosened. At this time, the spring 43 will pull the connecting plate 42 to move in the reverse direction through its own elasticity, and make the round rod 44 insert into the inner wall of the groove 2 7 to limit the adjusting block 41.

[0039] To restore the original state, release the limit of the round rod 44 on the adjusting block 41, and then push the adjusting block 41 to the right to make the guide plate 46 separate from the outer wall of the test roller 2. At this time, the torsion spring 47 will drive the guide plate 46 to reverse and reset through its own elasticity. At this time, the switching road surface assembly 4 can be retracted into the inner wall of the test roller 2.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
