[0019] 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.

[0020] Example:

[0021] Please see Figure 1-4A treadmill impact durability testing machine includes a test base 1 and a gantry frame 2. A rotary drive assembly 3 and a lifting device 4 are provided on the gantry frame 2. A lifting platform 5 is slidably connected to the gantry frame 2. A rotating shaft 6 is rotatably connected to the lower part of the lifting platform 5. The rotating end of the rotary drive assembly 3 is fixedly connected to the rotating shaft 6. A mechanical foot assembly is provided on the rotating shaft 6. The mechanical foot includes a main foot seat 701. Multiple foot pedal assemblies are provided on the main foot seat 701. The foot pedal assembly includes a mounting base 702, a swing arm 703, a pedal 704, and an elastic rope 705. A first set of setting rollers 9 and a second set of setting rollers 10 are fixedly connected to the main foot seat 701 and the swing arm 703, respectively.

[0022] A guide column 11 is fixedly connected to the gantry frame 2, and a limit screw 8 is rotatably connected to the gantry frame 2. By rotating the limit screw 8, the height of the limit platform 801 can be adjusted to adapt to the testing of treadmills of different heights. The guide column 11 can guide the sliding of the lifting platform 5 and the limit platform 801.

[0023] The main foot seat 701 is fixedly connected to the mounting seat 702 and the rotating shaft 6. The middle part of the swing arm 703 is hinged to the mounting seat 702. The second set roller 10 is fixedly connected to one end of the swing arm 703. The elastic rope 705 is sleeved on the first set roller 9 and the second set roller 10. A torsion spring is provided at the hinge point between the pedal 704 and the swing arm 703.

[0024] A stop bar 706 is fixedly connected to the side wall of the mounting base 702. The end of the stop bar 706 abuts against the pedal 704. When the pedal 704 is being tested, the pedal 704 first contacts the running belt of the treadmill and flips downward. When it moves away from the running belt, it will reset under the action of the torsion spring. During the reset process, the stop bar 706 blocks and limits it.

[0025] V-shaped grooves are provided on both the first set of rollers 9 and the second set of rollers 10. The elastic rope is placed in the V-shaped grooves to prevent the elastic rope from deviating. The elastic rope 705 is specifically made of latex rope.

[0026] The working principle of this utility model is as follows: During testing, the treadmill to be tested is placed on the test base 1. The height of the limiting platform 801 is adjusted according to the height of the treadmill's running belt. By rotating the limiting screw 8, the limiting platform 801 is raised and lowered along the guide column 11. During testing, the rotating drive assembly 3 drives the rotating shaft 6 to rotate. Then, the treadmill is started, and the running belt of the treadmill is in running state. Then, the lifting device 4 (the lifting device 4 can be a cylinder) drives the lifting platform 5 to descend until the lifting platform 5 descends onto the limiting platform 801. At this time, the mechanical foot will simulate the running state for testing. The specific actions are as follows: the main foot seat 701 will rotate relative to the rotating shaft 6, and the foot pedal assembly will press down on the running belt of the treadmill and then move away from the running belt. During this process, the pedal 704 first contacts the running belt of the treadmill and flips downward. When it moves away from the running belt, it will reset under the action of the torsion spring. During the reset process, the stop bar 706 blocks and limits it. This process is repeated to simulate the running state for testing. Within a specified time, the treadmill is tested to see if there is a malfunction.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
