Protection device for barbell exercise in gymnasium

Abstract

The invention discloses a protection device for barbell exercise in a gymnasium, and relates to the technical field of fitness equipment. The protection device for barbell exercise in the gymnasium comprises a shell; a magnetic block I is fixedly connected to the inner wall of the shell; clamping grooves which are uniformly distributed are formed in the inner wall of the shell; a rotating shaft isfixedly connected to the middle of the shell; a rotating block movably connected with the outer side of the rotating shaft is movably connected to the inner wall of the shell; a magnetic block II isfixedly connected to the inner wall of the rotating block; and a movable groove is formed in the inner wall of the bottom of the rotating block. According to the protection device for barbell exercisein the gymnasium, through cooperative use of clamping blocks and the clamping grooves, when a barbell is used for exercise and a body builder suddenly relieves force, the barbell suddenly falls downto drive the rotating block to rapidly rotate, the clamping blocks are thrown out under the action of centrifugal force at the moment, the clamping blocks and the clamping grooves are in clamped connection, rotation of the rotating block is effectively limited, and at the moment, a binding rope outside the rotating block does not move any more, so that the effect of limiting descending of the barbell is achieved, the safety of the body builder is effectively protected, and the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a protective device for barbell exercise in a gym. Background technique [0002] Fitness equipment is often divided into two categories: single-function and comprehensive multi-function according to the number of training functions. Commonly used are rowing machines, fitness bikes, walking machines, treadmills, waist shaping machines, etc. There are many types of fitness equipment at present. A kind of body-building equipment is exactly barbell, is mainly used for exercising lower body strength, and current barbell exercise effect is more obvious, but often can run into some problems in the use process, has potential safety hazard. [0003] Most of the current barbells are used by adding iron sheets of the same weight on both sides of the lever to exercise the muscles of the bodybuilder, and adjust the total weight of the iron sheets according to the different abilities...

Problems solved by technology

[0002] Fitness equipment is often divided into two categories: single-function and comprehensive multi-function according to the number of training functions. Commonly used are rowing machines, fitness bikes, walking machines, treadmills, waist shaping machines, etc. There are many types of fitness equipment at present. One kind of fitness equipment is the barbell, which is mainly used to exercise the strength of the lower limbs. The current barbell exercise effect is relatively obvious, but it often encounters some problems during use, and there are potential safety hazards

[0003] Most of the current barbells are used by adding iron sheets of the same weight on both sides of the lever to exercise the muscles of the bodybuilder, and adjust the total weight of the iron sheets according to the different abilities of each person, so there are often challenges. People with their own abilities often increase the weight of the barbell. At the same time, because there is no protective device during the barbell exercise, accidents sometimes occur.
