Description

Technical Field

[0001] The present application relates to the field of physical training equipment, and in particular to a physical training device for sports students. Background Art

[0002] Physical fitness is the body's fundamental athletic ability, demonstrated through strength, speed, endurance, coordination, flexibility, and agility. It is a crucial component of an athlete's competitive ability. Physical fitness levels are closely related to the body's morphological and functional characteristics. During physical training, routine physical training includes barbells, horizontal and parallel bars, running, sit-ups, and push-ups. Most physical training programs utilize specialized equipment, such as the horizontal bar, for movement training.

[0003] Publication No. CN 217311751 U discloses a physical training device for sports. The height of the crossbar can be adjusted by adjusting the height of the support device. The operation is simple and convenient, and it can be used by people of different heights, making it comfortable for people of different heights to use and highly practical. By providing an anti-slip cover, the user's comfort in holding the crossbar can be improved, and at the same time, the user can be prevented from sweating and falling due to not being able to hold the crossbar, thereby increasing safety.

[0004] However, there are some defects in the above solution: in order to adjust the height, the cross bar needs to be removed, and people need to step on the pedals to adjust it at the top, which is dangerous and troublesome. In addition, the cross bar is inside each side panel and is easy to rotate, affecting the normal use of sports students. Utility Model Content

[0033] Among them, the base 110 is provided with an inner cavity 111, the bottom end of the threaded rod 120 is rotatably set in the inner cavity 111, the transmission rod 140 is fixedly connected with the worm 141, the threaded rod 120 is fixedly sleeved with the worm wheel 121, the worm 141 and the worm wheel 121 are engaged with each other, and by setting the worm 141 and the worm wheel 121 to be engaged, the transmission rod 140 is rotated, the transmission rod 140 drives the worm 141 to rotate, the worm 141 drives the worm wheel 121 to rotate, and the worm wheel 121 drives the threaded rod 120 to rotate, thereby achieving the purpose of rotational connection.

[0034] Specifically, the transmission rod 140 rotates and passes through the inner cavity 111. One end of the transmission rod 140 is fixedly connected to a handwheel. By providing the handwheel, it is convenient to rotate the handwheel to drive the transmission rod 140 to rotate, which is convenient for personnel to operate and saves effort.

[0035] See also Figure 1 、 3 and 5. The connecting assembly 200 includes a fixing ring 210, a clamping rod 220 and an elastic member 250.

The spring 251 is arranged in the connecting cavity 132. The moving block 252 is placed in the connecting cavity 132 and abuts against the spring 251. The clamping rod 220 is fixedly connected to the moving block 252. By setting the spring 251 and the moving block 252, the elastic action of the spring 251 is used to push the moving block 252, so that in the absence of other external artificial forces, the moving block 252 drives the clamping rod 220 to remain clamped with the cross bar 150. When disassembling, the moving block 252 is pressed to squeeze the spring 251 and drive the clamping rod 220, so that the clamping rod 220 and the cross bar 150 are separated, which is convenient for disassembly and assembly.
