Example one

Referring to fig. 1, a horizontal bar for fitness training comprises a cross bar 1, wherein two ends of the bottom of the cross bar 1 are fixedly connected with upright posts 2, the outer side walls of the bottoms of the two upright posts 2 are fixedly connected through a same bottom plate 3, the bottom of the bottom plate 3 and the bottom of the upright posts 2 are positioned on the same horizontal plane, two pedal blocks 4 are arranged at the top of the bottom plate 3, a control groove 5 which is in an L shape and corresponds to the pedal blocks 4 is arranged in the bottom plate 3, the pedal blocks 4 are connected with the inner side wall of the control groove 5 in a sliding and sealing manner, the outer side walls of the pedal blocks 4 are fixedly connected with a rubber sealing layer, so that the pedal blocks 4 are connected with the inner side wall of the control groove 5 in a sliding and sealing manner, a first inserting rod 6 is fixedly connected with the inner bottom of the control groove 5, a first piston 7 is fixedly connected with the top of the first inserting rod 6, a control cavity which corresponds to the first piston 7 is arranged at the bottom, if the air pressure in the control cavity is the same as the outside in the state shown in fig. 1, when the exerciser steps on the pedal block 4, the pedal block 4 moves downwards due to the gravity of the exerciser, the space between the first piston 7 and the control cavity is reduced, and therefore the air pressure in the control cavity is increased and is larger than the outside air pressure, so that when the exerciser releases the pedal block 4, the pedal block 4 moves upwards and recovers due to the fact that the air pressure in the control cavity is larger than the outside air pressure, and the next use is facilitated.

Wherein, be equipped with horizontal cavity 8 in the horizontal pole 1, be equipped with vertical mouth 9 in the pole setting 2, horizontal cavity 8, vertical mouth 9 and control slot 5 communicate each other, two fixed pipes 10 that are the L type of interior bottom fixedly connected with of horizontal cavity 8, and horizontal cavity 8 and fixed pipe 10 intercommunication, the one end fixedly connected with that horizontal cavity 8 was kept away from to fixed pipe 10 is annular gasbag 11, and fixed pipe 10 and gasbag 11 intercommunication, make horizontal cavity 8 like this, vertical mouth 9 and control slot 5 intercommunication, then change gasbag 11's shape through the atmospheric pressure that changes in the control slot 5, thereby protect person's the arm through gasbag 11, prevent that the deflection of the wide-angle from appearing in wrist department.

Before the air bag rolling device is used, the horizontal cavity 8, the vertical port 9 and the control groove 5 are in a negative pressure state, and the air bag 11 is in a rolling state, because the air pressure in the air bag 11 is smaller than the air pressure outside.

During the use, firstly, the exerciser steps on the pedal block 4, the pedal block 4 moves downwards due to the gravity of the exerciser, the size of the control groove 5 is further reduced, the air pressure in the horizontal cavity 8, the vertical port 9 and the control groove 5 is increased, the air bag 11 is inflated, the air bag 11 is opened, at the moment, the wrist of the exerciser can conveniently pass through the air bag 11 and is held on the cross rod 1 by hands, the pedal block 4 is loosened by the foot of the exerciser in the exercise process, the pedal block 4 moves upwards due to the fact that the air pressure in the control cavity is larger than the external air pressure, the size in the control groove 5 is increased, the air pressure in the horizontal cavity 8, the vertical port 9 and the control groove 5 is reduced, the air bag 11 is made, the inner side wall of the rolled air bag 11 is tightly attached to the wrist of the exerciser, and the wrist of the exerciser is protected by the contracted air bag 11, prevents the wrist of the exerciser from deflecting during the exercise, and the air bag 11 can be made of rubber because the coefficient of static friction is large, so that the wrist of the exerciser can be better wrapped, and the wrist of the exerciser is less prone to deflecting.

After use, the exerciser's feet step on the footrests 4, so that the air cells 11 are spread, and the exerciser's wrists are conveniently moved down from the air cells 11.

Example two

Referring to fig. 2-3, the difference between this embodiment and the first embodiment is that the tightening degree of the airbag 11 can be adjusted, so that the airbag can be used by people with different wrist thicknesses, that is, the end of the cross rod 1 is rotatably connected with a threaded rod 12, one end of the threaded rod 12 away from the cross rod 1 is inserted with a second inserted rod 13, wherein the second inserted rod 13 is in a prism shape, so that the rotation of the second inserted rod 13 can drive the threaded rod 12 to rotate, one end of the second inserted rod 13 away from the threaded rod 12 is fixedly connected with a handle 14, the outer side wall of the second inserted rod 13 is sleeved with a spring 15, two ends of the spring 15 are respectively fixedly connected with the end of the cross rod 1 and the handle 14, two limit rods 17 are fixedly connected to the handle 14, the end of the cross rod 1 is provided with a plurality of limit grooves corresponding to the limit rods 17 around the axis of the threaded rod 12 as the center of a circle, one end of the threaded, wherein the second piston 16 is prismatic in order that it does not deflect with the rotation of the threaded rod 12. The using process is as follows: firstly, the handle 14 is pulled outwards, then the handle 14 is rotated, the rotation of the handle 14 drives the rotation of the threaded rod 12, the position of the second piston 16 is adjusted along with the rotation of the threaded rod 12, in this way, the air pressure of the initial state in the horizontal cavity 8, the vertical port 9 and the control groove 5 is changed, the tightening degree of the air bag 11 during rolling is changed, after the adjustment is finished, the handle 14 is loosened, then the handle 14 moves forwards under the action of the spring 15, the limiting rod 17 is combined with the limiting groove, and the situation that the second piston 16 moves due to the rotation of the threaded rod 12 is avoided.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
