pull up exercise machine

Abstract

The invention relates to a pull-up exerciser. The pull-up exerciser comprises a base and a stand column. The top end of the stand column is connected with a top cantilever in a pivoted mode, the tail end of the cantilever is connected with a linkage cable in a linked mode, the other end of the linkage cable drives a clamping-pulling rotating piece to rotate, the clamping-pulling rotating piece is constantly pulled by an elastic part, and a pull ring unit is arranged at the other end of the cantilever to pull a supporting plate to move vertically in cooperation with a pull rope and a plurality of pulleys. The bottom end of the stand column is connected with a rotating rod assembly in a pivoted mode, the other end of the rotating rod assembly is connected with the supporting plate in a pivoted mode, and an auxiliary pushing unit is arranged between the rotating rod assembly and the base and used for providing upward pushing force for the supporting plate. A linkage hook rod is arranged at the first axis point of the rotating rod assembly and connected with the rotating rod assembly coaxially, and the linkage hook rod cooperates with a corresponding hook column of the clamping-pulling rotating piece to constantly lock the low-point static position of the rotating rod assembly and the supporting plate. Only when the supporting plate bears gravity, the cantilever is pulled downwards, and the linkage rod hook is unlocked from the clamping-pulling rotating piece, can the supporting plate be pulled by the pull ring unit; when the external force of the pull ring unit disappears, the supporting plate descends under continuous gravity and restores to be locked to the low-point static position.

Description

technical field [0001] The invention belongs to the field of pull-up exercise equipment, and relates to a pull-up exercise device. Background technique [0002] The so-called "pull-up exerciser" is basically a kind of indoor sports equipment that simulates the "horizontal bar" or "rings" exercise of gymnastics. Of course, it can also be used to stretch the upper limbs or squat the lower limbs. The types of body movements depend on the user's familiarity with the equipment and their own exercise needs. It can be described as an extremely diverse and excellent indoor exercise and fitness equipment; The load source of motion gravity. Therefore, in design, in order to prevent the user's physical strength from being unable to load his own body weight for many times, an auxiliary pushing component (such as a spring pneumatic cylinder, etc.) is usually provided under the support plate to help the user To apply force, in short, when the user pulls down the pull ring unit located on...

[0003] Then, as mentioned above, since the auxiliary pushing assembly is constantly pushing the supporting plate, when the supporting plate is not in use, it is usually at a certain height position (depending on the push-out length of the auxiliary pushing assembly), so , when the user wants to step on the support board, it will be more inconvenient or even fearful. Of course, there are currently known products that place a stepped platform on the side of the raised support board to facilitate the user to step on the support board. , however, this will also make users feel scared psychologically, fearing that its sinking speed will exceed their expectations, and even produce a repulsive mentality that resists use. It shows that the design features of this mechanism are obviously difficult for users to easily agree with.

[0004] Furthermore, when the user finishes exercising and wants to leave the support board, it will also make the user feel hesitant and tormented, because once his body weight leaves the support board, the support board will be pushed by the auxiliary push assembly. It immediately rises up, so the user must be very careful and cautious to leave the support plate. However, the accidental news of the user's injury due to falling from this type of sports equipment is still heard from time to time, which shows that its design has potential. disadvantages, but need to be improved
