Horizontal bar with protective effect for physical exercise

Abstract

The invention relates to a horizontal bar for physical exercise, and in particular, relates to a horizontal bar with a protective effect for physical exercise. The horizontal bar with the protection effect for physical exercise aims at achieving the technical purposes that the horizontal bar can be protected, and the situation that due to rainwater erosion, protection paint falls off, and use is affected is avoided. The horizontal bar with protection effect for physical exercise comprises a base, four supporting rods are symmetrically and fixedly connected to one side of the base, every two supporting rods on each side form a group, and the horizontal bar is arranged between the sides, away from the base, of the four supporting rods. According to the invention, a driving groove plate is pulled to move downwards, so a protective frame swings outwards to prevent the horizontal bar from being blocked, an exerciser can start exercising through the horizontal bar, after exercising is completed, the driving groove plate is loosened, the protective frame swings inwards to reset to protect the horizontal bar, and thus the situation that rainwater falls onto the horizontal bar to corrode the horizontal bar, and consequently protective paint falls off to affect use is avoided.

Description

technical field [0001] The invention relates to a horizontal bar for physical exercise, in particular to a horizontal bar for physical exercise with protective effect. Background technique [0002] The horizontal bar is one of men's competitive gymnastics events. In 1896, the horizontal bar was listed as an Olympic event. The horizontal bar used in modern competitions is fixed on two pillars by an iron horizontal bar with a diameter of 2.8 cm, and the two ends are fixed with steel cables. The horizontal bar is 2.55 meters above the ground. The complete set of moves on the horizontal bar is all composed of swinging movements without stopping. Actions include forward and backward giant loops, various grip changes, body loops, various twists, arm twisting grips and flying movements. The bar is 2.4 meters long, 2.8 centimeters in diameter, and 2.55 to 2.75 meters high, and the two ends of the bar are respectively fixed on the pillars. The horizontal bar can cultivate a brave ...

AI Technical Summary

Problems solved by technology

The adjustable fitness horizontal bar rotates the first baffle plate counterclockwise, so that the threaded rod rotates counterclockwise, and the threaded rod is connected with the nut thread, and moves inwardly through the connecting plate, so that the fourth connecting rod moves inwardly. The fourth connecting rod moves inwardly, so that the third backing plate cannot fit the first sliding sleeve, so as to fix the sliding sleeve. The above-mentioned patent has the following disadvantages: rainwater is easy to fall on the horizontal bar, causing The horizontal bar is eroded by rainwater and the paint is peeled off. The peeling of the protective paint will affect the use of the horizontal bar by the exercisers.

[0004] Therefore, there is a special need for a horizontal bar for physical exercise with a protective effect that can protect the horizontal bar from the erosion of rainwater and cause the protective paint to fall off, so as to solve the problems in the prior art
