Embodiment 1

[0026] like figure 1 As shown, the present invention provides an anti-injury sports equipment for muscle training, including a bracket 101 and a dumbbell 102, and also includes: a first hydraulic cylinder, a diverter valve 105 and a second hydraulic cylinder, the first hydraulic cylinder and the first cylinder The body 103 is vertically arranged on the support 101, the first piston 104 of the first hydraulic cylinder is connected with the dumbbell 102; the liquid inlet 106 of the diverter valve 105 is communicated with the first cylinder 103, and the diverter The liquid outlet A107 of the valve 105 is connected with the first one-way valve 108; the second piston 109 of the second hydraulic cylinder divides the inner cavity of the second cylinder 110 of the second hydraulic cylinder into an upper cavity 111 and a lower cavity 112, The upper cavity 111 communicates with the first one-way valve 108 and the liquid outlet B113 of the diverter valve 105 at the same time. The cross-s...

Embodiment 2

[0031] On the basis of Embodiment 1, in order to be able to adjust the resistance of the diverter valve 105 to the flow of hydraulic oil, thereby changing the resistance of the dumbbell 102 when it is lifted up and the speed of the dumbbell 102 falling freely when it is released, so as to apply the dumbbells 102 of different self-weights, improve the The scope of application of this sports equipment.

[0032] like figure 1 As shown, wherein the diverter valve 105 is slidably connected with a slide bar 201, the slide bar 201 is provided with a first orifice 202 and a second orifice 203, and one end of the first orifice 202 is connected to the liquid outlet. Port A107 is communicated with, one end of the second orifice 203 is communicated with the liquid outlet B113, the other end of the first orifice 202 is communicated with the first one-way valve 108, and the other end of the second orifice 203 is communicated with the The upper cavity 111 is communicated.

Abstract

The invention discloses an anti-injury sports apparatus for muscle training, and belongs to the technical field of sports training equipment. The anti-injury sports equipment for muscle training comprises a support and a dumbbell, and further comprises a first hydraulic cylinder, a second hydraulic cylinder, a first connecting rod, a second connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, a liquid inlet of the diverter valve is communicated with the first cylinder body, and a liquid outlet A of the diverter valve is communicated with a first one-way valve; an inner cavity of a second cylinder body of the second hydraulic cylinder is divided into an upper cavity body and a lower cavity body by a second piston, the upper cavity body is communicated with the first one-way valve and a liquid outlet B of the diverter valve at the same time, and the first one-way valve is used for being communicated from the liquid outlet A to the upper cavity body in a one-way mode. The anti-injury sports equipment for muscle training not only can assist a user in weight lifting training, but also can prevent the dumbbell from falling rapidly to injure a trainee when the dumbbell of the trainee slips out of the hand.

Description

technical field [0001] The invention relates to the technical field of sports training equipment, in particular to an anti-injury sports equipment used for muscle training. Background technique [0002] Many sports require muscle training, muscle strength, and physical performance in the early stages. Regular muscle training can also improve the excitability of nerve cells, so that muscles and tendons are in a better state, improve muscle and tendon elasticity and stretch, thereby preventing muscle and tendon strain or tear. Nowadays, in order to improve the training efficiency and training effect, it is necessary to use some corresponding sports equipment during muscle training. Among them, dumbbells are often used for upper limb muscle training, and users can choose dumbbells of different weights and specifications for lift training according to their own conditions. The user will sweat during the training process, and the grip of the hand will gradually decrease, and th...
