Description

A self-help body-building abdominal crunching device

technical field

The utility model relates to the field of body-building equipment, in particular to a self-service body-building belly-rolling device.

Background technique

At this stage, it is the dream of every fitness enthusiast to shape the muscles of the whole body of the exerciser through fitness exercises. They also enjoy the changes in the body with the growth of fitness time, but in reality, there is such a problem that troubles the majority of people. The problem for fitness enthusiasts is that with the continuous growth of their fitness time, the muscles of all parts of the body have taken shape, but the abdominal muscles have not been revealed, and no matter how hard they exercise, the effect is not obvious. Only a very small number of people can get a perfect muscular body by breaking through the barriers of abdominal exercise to their own fitness. In fact, this is the case. The reason is very simple, that is, it is difficult to exercise the abdominal muscles effectively. Studies have shown that the formation of abdominal muscles The most effective way to keep fit is abdominal crunching. However, not every fitness enthusiast can effectively persist in crunching. There are two reasons. First, crunching can’t borrow any external force. Painful, in reality, even many people can’t even do a standard crunching exercise; second, during routine crunching exercises, they can’t better control the muscles to be exercised, even if they sweat a lot, they only have a certain amount of muscle. The muscles at the right position have been exercised, and other parts have not been effectively exercised.

Utility model content

The technical problem to be solved by the utility model is to provide a self-service body-building abdominal crunching device for the above-mentioned deficiencies in the prior art.

In order to solve the above technical problems, the utility model proposes the following technical solutions: a self-service body-building abdominal crunching device, which includes a flat stool, and the inner and outer sides of the lower left side of the flat stool are provided with two leg limiters through two installation rods , There is a leg-protecting sponge foam at both ends of the leg-limiting frame, and an S-shaped back support is provided on the right side of the flat stool through the lower installation rod, and a plurality of back-protecting sponge foams are arranged on the S-shaped back support. The left end of the flat stool is provided with an L-shaped frame rod. One end of the L-shaped frame rod is fixed to one end of the flat stool through threads, and the other end is provided with a fixed pulley. One side of the fixed pulley is provided with a limit groove. The tension on the fixed pulley The rope is connected with the S-shaped back support frame through a threaded sleeve at one end, and the other end of the tension rope is provided with a power-assisted cross bar.

The leg limiting frame is fixed on the mounting rod on the lower left side of the flat stool through nuts.

Two threaded short rods protrude from the top of the S-shaped back support frame.

The tension rope has certain elasticity.

The utility model has the following beneficial effects:

With the above-mentioned structure, when the exerciser performs abdominal exercises, he or she should first sit flat on the flat stool, make both legs fixed by the leg-protecting sponge foam support on the leg limiter on the left side of the flat stool, and lean against the back on the right side of the flat stool. On the S-shaped back support frame, hold the two ends of the power-assisted crossbar with both hands. When starting the abdominal crunch exercise, the exerciser pulls the power-assisted crossbar through the arm, and the device will transmit the force to the flat bench through the fixed pulley and tension rope above the device. The S-shaped back brace on the right side realizes the power-assisted exercise of the abdomen and reduces the pain caused by the lack of waist strength of the exerciser. The control of the rotation arc range of the frame can further realize the controlled exercise of different muscle blocks of the abdomen. The design is simple in structure, easy to operate, strong in practicability and easy to popularize.

In the figure: flat stool 1, installation rod 2, leg limit frame 3, leg protector sponge foam 4, S-shaped back support frame 5, back protector foam foam 6, L-shaped frame rod 7, fixed pulley 8, limit groove 9 , tension rope 10, threaded sleeve 11, power-assisted cross bar 12, threaded short bar 5-1.

detailed description

Embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1-2, a kind of self-service body-building abdominal crunching device, it comprises flat stool 1, and flat stool 1 is provided with two leg limit frames 3 through two mounting rods 2 on the inside and outside of the lower left side. The two ends of the position frame 3 are respectively provided with a leg-protecting sponge foam 4, and the right side of the flat stool 1 is provided with an S-shaped back support frame 5 through the installation rod 2 below, and a plurality of back-protecting sponges are arranged on the S-shaped back support frame 5 Foam 6, flat stool 1 left end is provided with L-shaped frame bar 7, and one end of L-shaped frame bar 7 is fixed on an end of flat stool 1 by thread, and the other end is provided with fixed pulley 8, and one side of fixed pulley 8 is provided with Limit slot 9, the tension rope 10 on the fixed pulley 8 is connected with the S-shaped back brace 5 through the threaded sleeve 11 at one end thereof, and the other end of the tension rope 10 is provided with a booster cross bar 12 .

Further, the leg limiting frame 3 is fixed on the installation rod 2 on the lower left side of the flat stool 1 through nuts.

Further, there are two threaded short rods 5 - 1 protruding from the upper part of the S-shaped back support frame 5 , and the tension rope 10 can be connected with the S-shaped back support frame 5 through the threaded sleeve 11 .
