Fitness device with protection function

Abstract

The invention discloses a fitness device with a protection function, and relates to the technical field of fitness equipment, the fitness device comprises a machine body, a cavity is formed in the middle of the machine body, sliding grooves are communicated with the two sides in the cavity, sliding blocks are slidably connected in the two sliding grooves, the opposite sides of the two sliding blocks are fixedly connected with the same fitness rod, and the fitness rod is fixedly connected with the body. According to the fitness equipment, a fitness person pushes the fitness rod upwards with the two hands, the fitness rod moves to drive the control mechanism through the sliding block, the piston block in the control mechanism compresses the air storage cavity above the piston block, the air storage cavity is compressed through the air storage cavity, and therefore the fitness rod can be driven to move through the air storage cavity; the ventilation rate of the ventilation pipe between the air storage cavities at the top and the bottom of the machine body is low, so that when the fitness rod moves upwards at a certain speed, the air pressure in the air storage cavity at the top of the machine body is increased to form resistance which is confronted with the force generated by the two hands of the body builder, and the exercise and fitness effects are achieved for the body builder.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a fitness device with a protective function. Background technique [0002] When traditional fitness equipment is used, it generally requires the guidance of a fitness coach before it can be used. If it is used privately, it will not only fail to achieve better exercise and fitness effects, but will easily damage itself. In fitness equipment, the barbell is a kind of strength training equipment. During bench press training, the weight of the barbell can be changed by increasing or decreasing the barbell plates, so as to achieve the corresponding exercise effect. However, when using a barbell for bench press training, when it is necessary to gradually increase the training gravity, the fitness personnel need to repeatedly install and disassemble the barbell, which is not only troublesome but also interrupts the training process and affects the training effect; and, in cas...
