Description

Technical Field

[0001] This utility model relates to the technical field of luggage wheel wear testing machines, and in particular to a device for testing the durability of suitcase wheels. Background Technology

[0002] The luggage wheel wear tester is a device used to evaluate the durability and structural stability of luggage wheels. It simulates the use of luggage when walking and conducts continuous walking tests on the wheels. During the test, an appropriate load is applied to the luggage, and the friction and impact between the test roller and the pulley generate impact vibration and wear on the sample.

[0003] When using a luggage wheel abrasion testing machine, the wheel sample is first fixed to a lifting rod with bolts. The rod is lowered to bring the wheel close to the test roller, thus conducting a wheel durability test. The specific data will be displayed on the equipment's screen. However, this type of testing machine has some inconveniences. The surface roughness of its test roller is uniform, while in reality, the roughness of different road conditions varies. To simulate these situations, it is necessary to frequently change test rollers with different roughness. This operation not only increases the complexity of the testing process but also consumes additional time and manpower, greatly reducing the ease of use of the luggage wheel abrasion testing machine.

[0004] Therefore, in response to the above problems, a new device for testing the durability of suitcase wheels is proposed. Utility Model Content

[0005] To overcome the problems existing in related technologies, this utility model provides a device for testing the durability of suitcase wheels. It can combine test rollers with different roughnesses and move the test rollers to facilitate contact between the wheel sample and the surface of the test rollers with different roughnesses, thereby improving the convenience of the suitcase wheel wear testing machine.

[0006] To achieve the above objectives, the first aspect of this utility model provides an apparatus for testing the durability of suitcase wheels, comprising:

[0007] The main body of the testing machine, the lifting rod, the sample body, the durability testing mechanism, and the counterweight adjustment mechanism;

[0008] The main body of the testing machine is equipped with a lifting rod, and the sample body is bolted to the lifting rod. The main body of the testing machine is equipped with a durability testing mechanism to improve the testing effect. A counterweight adjustment mechanism for counterweight is installed on one side of the lifting rod.

[0009] The durability testing mechanism includes an assembly base, a first test wheel, a second test wheel, a third test wheel, and an extrusion plate;

[0010] An assembly base is rotatably installed inside the main body of the testing machine. A first test wheel is slidably connected to the assembly base.

[0011] Furthermore, the surface roughness of the second test wheel is greater than that of the first test wheel, and the surface roughness of the third test wheel is greater than that of the second test wheel.

[0012] Furthermore, the durability testing mechanism also includes a drive motor, a rotating plate, and a first electric push rod;

[0013] The main body of the testing machine is equipped with a drive motor. The output shaft of the drive motor is fixedly connected to a rotating plate. The first electric push rod is symmetrically mounted on the rotating plate. The output shaft of the first electric push rod is fixedly connected to the assembly base.

[0014] Furthermore, the counterweight adjustment mechanism includes an adjustment mounting bracket, a first limiting block, a counterweight body, and a second limiting block;

[0015] An adjustment mounting bracket is fixedly connected to one side of the lifting rod. A first limiting block is slidably installed inside the adjustment mounting bracket. The first limiting block contains a counterweight body. A second limiting block located above the counterweight body is fixedly connected to the inner wall of the adjustment mounting bracket.

[0016] Furthermore, the counterweight adjustment mechanism also includes a first threaded rod, a drive rod, and a displacement block;

[0017] The adjusting mounting bracket has a first threaded rod symmetrically rotatably connected inside. The top end of the first threaded rod passes through the upper surface of the adjusting mounting bracket. A drive rod is rotatably connected to the lifting rod. The top end of the first threaded rod is connected to the surface of the drive rod through a bevel gear. A displacement block is symmetrically fixedly connected to the first limit block and is slidably connected to the adjusting mounting bracket. The first threaded rod is engaged with the displacement block.

[0018] Furthermore, a lifting mechanism for moving the lifting rod up and down is installed on the upper surface of the main body of the testing machine;

[0019] The lifting mechanism includes a lifting mounting shell and a second threaded rod;

The top end of the second threaded rod passes through the upper surface of the lifting mounting shell, and the second threaded rod is engaged with the lifting rod.

[0021] Furthermore, a second electric push rod located below the lifting rod is fixedly connected to the main body of the testing machine. A concave block is fixedly connected to the moving end of the second electric push rod, and the inner wall of the concave block is in contact with the lower surface of the lifting rod.

[0022] The technical solution provided by this utility model can include the following beneficial effects:

[0023] In this example, by installing a durability testing mechanism, when different road conditions need to be simulated to conduct durability tests on the sample body, the moving end of the first electric push rod will adjust accordingly according to the preset program or operation command. As it extends or shortens, it will drive the first, second, and third test wheel components connected to it, so that their surfaces are in full contact with the sample body. Through this dynamic contact method, the sample body can be tested under simulated road conditions with different roughness and different friction. This design cleverly avoids the trouble of frequently changing test components, greatly improves the convenience of the bag wheel wear tester, and makes the testing work more efficient and accurate.
