Description

Technical Field

[0001] The utility model relates to the technical field of sports training, in particular to an air resistance type deep squat training device. Background Art

[0002] In competitive sports, the way to improve performance is to train persistently, and auxiliary training equipment plays a vital role in improving performance. For example, in competitive events such as sprinting, high jump, javelin, and ball games, the explosive power generated in a short period of time is one of the important factors that determine the quality of performance. How to strengthen and improve the explosive power of athletes, especially the explosive power training of lower limbs, through auxiliary training equipment is a difficult problem faced by existing training equipment.

[0003] The training of lower limb explosive power requires more training of the muscle groups in the buttocks, thighs and abdomen, and squats are a set of trump movements to train the lower limb muscles. Athletes can significantly improve the explosive power of the lower limbs by performing squat training under weight-bearing conditions, through the coordination of the feet, calves, thighs, hips and waist. At present, athletes mainly train around the project of lifting barbells. Athletes adjust the weight of the barbell plates according to their own conditions to achieve the purpose of squat training. However, this type of training still has some major drawbacks: first, the barbell lifting action is mainly divided into two steps: lifting and lowering. Explosive force training is mainly concentrated in the lifting step. When lowering, the barbell accelerates down under the action of gravity inertia, and the force generated is the swing force. Therefore, athletes have to bear a weight far exceeding the weight of the barbell plates, and the swing force is unstable and uncontrolled, which is bound to increase the load on the athletes' knees and increase the possibility of straining the calf and thigh muscles. Secondly, when squatting, the weight of the barbell plates needs to be continuously increased so as to continuously improve the explosive power. However, the weight that one bears is not easy to judge, and the coach is often required to hold the barbell on the side to prevent safety accidents such as being hit. Utility Model Content

The outer end of the linkage beam 8 movably passes through the support member 5. Force beams 9 connected to the upper rotating roller 6 are symmetrically arranged on the front and rear sides of the support member 5. A connecting beam 10 connected to the two force beams 9 is arranged on the left side of the support member 5. The connecting beam 10 is connected to the linkage beam 8 through an adjusting component. An upper hinge seat 11 is arranged above the support member 5, and a lower hinge seat 12 is arranged in the middle of the linkage beam 8. The cylinder seat of a cylinder 13 is movably hinged in the upper hinge seat 11, and the end of its piston rod is movably hinged in the lower hinge seat 12. An air supply mechanism connected to the cylinder 13 is arranged on the chassis at the right end, and a pedal 14 is arranged on the chassis at the left end; a screen display 15 is arranged on the left side of the top of the support member 5.

[0026] Optionally, the adjustment component includes a connecting hinge seat 16 arranged at the bottom of the connecting beam 10, the upper end of a square outer sleeve 17 is movably hinged in the connecting hinge seat 16, and a plurality of upper positioning holes 18 are provided on the square outer sleeve 17 at intervals along its length direction, a square inner sleeve 19 is movably clamped in the square outer sleeve 17, and a plurality of lower positioning holes 20 are provided on the square inner sleeve 19 at intervals along its length direction, a locking pin 21 is provided on one side of the square outer sleeve 17, and the locking pin 21 passes through one of the upper positioning holes 18 and the lower positioning hole 20, thereby fixing the square inner sleeve 19 in the square outer sleeve 17, and clamps 22 are symmetrically provided on the front and rear sides of the outer end of the linkage beam 8, and the lower end of the square inner sleeve 19 is movably hinged between the two clamps 22.

[0027] Optionally, the support member 5 includes a support frame 501 , in which limit beams 502 are horizontally arranged at the upper and lower ends, respectively, the upper hinge seat 11 is arranged on the right side wall of the upper limit beam 502 , and the linkage beam 10 is arranged between the two limit beams 502 .

[0028] Optionally, the air supply mechanism includes a base plate 23 arranged on the base frame, a compressor 24 is provided on the base plate 23, the compressor 24 is connected to the air supply tank 25 via a pipeline, each of the cylinders 13 is connected to the air supply tank 25 via a pipeline, a control device 26 is provided on the base plate on one side of the compressor 24, and the display 15 and the compressor 24 are respectively connected to the control device 26 via wires.

[0029] Optionally, a buffer tank 27 is further provided on the bottom plate, and the buffer tank 27 is provided on the pipeline between the compressor 24 and the air supply tank 25. When the air resistance needs to be increased, the air in the buffer tank 27 can be added to the air supply tank 25, thereby increasing the air pressure in the air supply tank 25, and then increasing the air resistance of the cylinder 13. In addition, the compressor 24 is not directly connected to the air supply tank 25, which can further improve the stability of the air pressure in the air supply tank 25.

[0030] Optionally, a buffer sponge 28 is provided at the bottom of the outer ends of the two force beams 9. The shoulders of the athlete are in contact with the buffer sponge 28, which can improve the comfort of use.

[0031] Optionally, handles 29 are symmetrically provided on the outer side walls of the two force beams 9. This facilitates athletes to grasp the handles 29 with both hands when "lifting", further improving the safety of use.

[0032] Optionally, the upper part of each of the fixed beams 2 is tilted to the left, so that the cylinder 13 is more vertical, so that the cylinder 13 provides a stable air resistance, which is convenient for athletes to use.

[0033] Optionally, a buffer pad 30 is provided on the lower limiting beam 502 corresponding to the position of the linkage beam 10. This reduces the damage of the linkage beam 8 to the limiting beam 502 when the cylinder 13 recovers its deformation, thereby increasing the service life of the device.

[0034] Before using the device, the height of the force beam 9 needs to be adjusted according to the height of the athlete. First, the locking pin 21 is removed, and the offset length between the square outer sleeve 17 and the square inner sleeve 19 is adjusted. The shorter the offset length between the two, the lower the height of the force beam 9. After the position is determined, the locking pin 21 is passed through the upper positioning hole 18 and the lower positioning hole 20 to fix the position of the square outer sleeve 17 and the square inner sleeve 19 to remain unchanged.

[0035] When the device is in use, the athlete stands on the pedal 14 of the chassis, extends the head upward from the middle of the two force beams 9, and makes the athlete's shoulders stuck on the buffer sponge 28 of the force beams 9, and then grasps the handles 29 with both hands, exerts force with both legs, and pushes up the two force beams 9. As the force beams 9 move upward, the linkage beam 8 is driven to move upward through the connecting beam 10 and the adjustment component, and the linkage beam 8 flips upward along the axis of the lower rotating roller 7, thereby making the piston rod of the cylinder 13 do a recovery movement, and the air resistance generated by the cylinder 13 provides a stable resistance for the athlete's "lifting". When "falling", the piston rod of the cylinder 13 returns to the initial position. This swing force is more linear and stable, and will not produce inertial acceleration, thereby fundamentally reducing the damage to the athlete's knees, especially making the forces received by the two steps of "lifting" and "falling" consistent, thereby further reducing the possibility of straining the athlete. Athletes can adjust the compressor 24 to charge and discharge the air supply tank 25 through the control device, thereby increasing or decreasing the air pressure in the air supply tank 25, and further adjusting the size of the air resistance. Without the assistance of others, the purpose of training and improving explosive power can be achieved, and safety accidents such as being hit can be avoided, which is conducive to improving competitive performance and solves the problems existing in the prior art.
