Description

Technical Field

[0001] The utility model relates to the technical field of police physical training, in particular to a teaching aid for police physical training. Background Art

[0002] Police physical training is the foundation of police physical training, which mainly includes endurance, strength, speed, agility, etc. It can improve the police's physical quality and physical fitness level through long-distance running, swimming, weightlifting, push-ups and other methods, and provide a solid physical foundation for performing various tasks. The use of teaching aids is indispensable in police physical training. The teaching aids have various shapes. Among them, the teaching aids for police physical training generally use obstacle bars for training.

[0003] A Chinese patent discloses a physical training device for police physical education teaching (authorization announcement number CN211752350U). This patented technology pushes the splint, and the splint moves to drive the arc plate to move through spring one, and the arc plate moves to fit with the annular side surface of the support rod. The splint continues to move to compress the spring one, so that the spring one generates elastic force. The splint moves to make the rectangular through groove on the annular side surface of the round rod leak out, and then the clamping block is installed inside the rectangular through groove. Under the action of the elastic force of the spring one, the splint moves to fit with the clamping block, and then the installation of the splint and the support plate is completed, which solves the problem of lack of convenient installation function of the support plate, resulting in the general use of sponge pads placed on the ground, which easily causes the sponge pads to slide against the ground and cause damage to the sponge pads.

[0004] However, there are still some shortcomings in this patent. Although the teaching aids in this patent can provide the purpose of police physical training, it can be seen from the drawings of this patent that this patent can only achieve a single climbing training in actual use, and cannot provide other training, resulting in low practicality. Therefore, those skilled in the art provide a teaching aid for police physical training to solve the problems raised in the above background technology. Utility Model Content
