An explosive pull-up bar

Abstract

The invention belongs to the field of sport equipment and particularly relates to an explosive type pull-up brace. The explosive type pull-up brace comprises a brace body, wherein force accumulation structures are symmetrically arranged at two ends of the brace body; each force accumulation structure comprises a swing claw, a cantilever claw and a pulling rope, the cantilever claws are of an arc-shaped rodlike structure and are upwarped, the swing claws are hinged to the end parts of the brace body, one end of each pulling rope is fixed on the cantilever claw of the force accumulation structure on the other side of the brace body, and the other end bypasses a fixed pulley and then is connected with the free end of a connecting rod. By means of the force accumulation structures, falling force produced by body weight of a trainer is subjected to energy storage and energy is stored by elastic deformation of the pulling ropes, when the trainer performs explosive type pull-up actions, energy stored in the pulling ropes is released with loosening of the swing claws, the step of the salmon ladder is lowered, so that part of body weight is offset, trainer's strength required to be explodedis reduced, physical ability consumption is reduced, the trainer can rapidly adapt to the sports, action essentials are mastered, and the competition result is improved.

Description

technical field

[0001] The invention belongs to the field of sports equipment, and in particular relates to an explosive pull-up brace. Background technique

[0002] Explosive pull-ups are also called salmon ladder pull-ups in the industry. The trainer uses the support bar to do a quick pull-up movement on two sets of salmon ladders placed vertically and symmetrically, and takes advantage of the trend to move the support bar in his hand. The bar moves upwards and is hung on a higher step. This sport requires extremely high strength of the upper body of the trainer. It requires the trainer to have great arm strength, endurance and explosive power. It can consume a lot of physical energy in a short time and has excellent However, in order to avoid muscle damage, beginners need to carry out long-term adaptive training before they can carry out the actual training of explosive pull-ups. The training time is long and it is difficult to achieve results. Contents of the invention...
