[0023] The barbell 4 is composed of a barbell sheet 1, a barbell support frame 2, a barbell rod 3, a locking bushing 5, and a barbell locking nut 6. The locking bushing 5 is connected to the barbell sheet 1, and the barbell sheet 1 is connected to the barbell Lock nut 6 , the barbell bar 3 is connected to the barbell support frame 2 , and the barbell bar 3 passes through the center of the locking shaft sleeve 5 , the barbell plate 1 and the barbell locking nut 6 .
[0024] The barbell support frame 2 is composed of a positioning pin hole 7, a slideway 13, and a safety contact button 15. The positioning pin hole 7 is connected to a positioning pin 14, and the position of the positioning pin 14 is adjustable, which can block the barbell 4 in the slideway. 13 at a certain height to ensure the safety of people, the safety contact button 15 is at the bottom of the slideway 13, when the positioning pin 14 is taken out, the sudden drop of the barbell 4 can trigger the safety contact button 15, the barbell support frame 2 is connected to the bottom plate 10, The lower part of the bottom plate 10 is connected to the wheel 8 , and the air pump 9 is on one side of the bottom plate 10 .
[0025] The safety contact button 15 is composed of a safety contact button piston 29 and an air outlet hole 28. The upper part of the safety contact button piston 29 is connected to the air outlet hole 28, and the lower part of the safety contact button piston 29 is connected to the air cavity 27. Under normal working conditions, The safety contact button 15 is closed, and the safety contact button piston 29 closely fits the air outlet 28 under the action of the pressurized gas. When the safety contact button 15 is triggered, the safety contact button piston 29 moves down, and the air outlet 28 releases the pressure gas. The bench press pad 22 moves down to drive the person to move down, thus playing a protective role.
[0026] The bench press pad 22 is composed of a first bench press pad 12, a second bench press pad 17, a first bench press pad support device 11, a second bench press pad support device 16, and a bench press pad connection device. 18, the lower part of the first bench press pad 12 is connected to the first bench press pad support device 11, the lower part of the second bench press pad 17 is connected to the second bench press pad support device 16, the first bench press pad support device 16 The bench press pad 12 is connected to the second bench press pad 17 through the bench press pad connection device 18 , and the angle of the first bench press pad 12 and the second bench press pad 17 can be adjusted through the bench press pad connection device 18 .
[0027] The first bench press pad support device 11 and the second bench press pad support device 16 are composed of a bench press pad bracket 23 , a bench press pad support shell 24 , an air inlet 25 , and a bench press pad support piston frame 26 The upper part of the bench press pad support 23 is connected to the bench press pad 22, the lower part of the bench press pad bracket 23 is connected to the bench press pad support piston frame 26, and the bench press pad support piston frame 26. 26 is connected to the bench press support shell 24, the bench press support shell 24 is internally connected to the air cavity 27, and the lower part of the bench press support shell 24 is connected to the bottom plate 10.
[0028] The bench press pad connecting device 18 is composed of a bench press pad fastening bolt 19, a washer 20, and a bench press pad lock nut 21. The bench press bolt 19 is connected to a gasket 20, and the gasket 20 is connected The bench press pad 22 is connected to the bench press pad lock nut 21 .
[0029] The barbell bar 3 is provided with a rubber massage needle 32 and a barbell anti-slip pattern 33. The rubber massage needle 32 is connected to the barbell anti-slip pattern 33. When the barbell 4 is bench-pressed, the rubber massage needle 32 has a massage effect on the upper acupoint of the hand, so the The positioning pin 14 is provided with a safety hole 30 and a positioning pin anti-slip 31. When bench-pressing, the safety hole 30 can be fastened with an iron wire to prevent it from slipping off.
[0030] Working principle: Adjust the angle of the first bench press pad 12 and the second bench press pad 17 through the bench press pad connection device 18, turn on the air pump 9, fill the air cavity 27 with pressurized gas, and press the barbell 3 according to your own. Height, adjust the position of the positioning pin 14. Under normal working conditions, the safety contact button 15 is closed, and the safety contact button piston 29 closely fits the air outlet 28 under the action of the pressurized gas. When the safety contact button 15 is triggered, the safety contact button The piston 29 moves down, the air outlet 28 releases the pressurized gas, and the bench press pad 22 moves down to drive the person to move down, thereby playing a protective role.
[0031]For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principle and spirit of the present invention, changes, modifications, substitutions and alterations to the embodiments still fall within the protection scope of the present invention within.
