They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-6 As shown, a bench press fitness device includes a support frame 101, a sliding frame 102 slidably connected to the lower end of the support frame 101, a control module 103 fixedly installed on one front end of the sliding frame 102, a connecting mechanism on the control module 103, and a protective mechanism on the support frame 101.

[0028] The protective mechanism includes two electrically operated telescopic rods 404, which are fixedly installed on the lower front side of the support frame 101. The two electric telescopic rods 404 are symmetrical about the sliding frame 102. A support plate 405 is fixedly installed on the upper end of the electric telescopic rods 404, and the support plate 405 abuts against the support frame 101. The side of the support plate 405 closest to the support frame 101 is inclined downward. Multiple limiting grooves 406 are equidistantly opened at the front end of the support frame 101. The limiting grooves 406 are located above the support plate 405 and parallel to the support plate 405. A barbell rod 60 is installed in the limiting groove 406. 1. When using, first push the barbell bar 601 to disengage it from the limiting groove 406. If the barbell bar 601 cannot be effectively controlled during training, activate the electric telescopic rod 404 through the connecting mechanism. This will cause the symmetrical electric telescopic rod 404 to drive the support plate 405 to rise synchronously, pushing the barbell bar 601 upward. The barbell bar 601 will remain in contact with the front end of the support frame 101 during the upward movement. When the barbell bar 601 rises to the limiting groove 406, it will roll into the limiting groove 406 by its own weight.

[0029] The connecting mechanism includes a plug 401, with an insulating spacer fixed to one side of the plug 401. The insulating spacer is inserted into the control module 103. A connecting rope 402 is fixedly connected to the side of the plug 401 away from the control module 103. A tension strap 403 is fixedly connected to the movable end of the connecting rope 402. Velcro is provided at the overlap of the tension strap 403. Two symmetrical terminals are fixed inside the control module 103. Connecting springs are installed in the two terminals to make them abut against each other. When the plug 401 is inserted into the control module 103, the insulating spacer is located between the two terminals. In use, the tension strap 403 is fixed to the ankle with Velcro. In case of danger, the leg is kicked outward, and the insulating spacer of the plug 401 is pulled out through the connecting rope 402, so that the two terminals are connected and a signal is transmitted to the controller.

[0030] A lower lying plate 201 is fixedly installed on the upper end of the sliding frame 102. The lower lying plate 201 is located on the front side of the sliding frame 102. An upper lying plate 202 is hinged to the rear end of the lower lying plate 201. An adjustment mechanism is provided between the upper lying plate 202 and the sliding frame 102.

[0031] The adjustment mechanism includes an adjustment screw 301, which is rotatably connected to the upper end of the sliding frame 102. The adjustment screw 301 is threadedly connected to a moving block 302, which is slidably connected to the sliding frame 102.

[0032] A turntable is rotatably connected to the rear end of the sliding frame 102. The turntable is fixedly connected to the adjusting screw 301. A connecting rod 303 is hinged to the moving block 302. The end of the connecting rod 303 away from the moving block 302 is rotatably connected to the upper lying board 202. When it is necessary to adjust the upper body angle, the turntable is rotated to drive the adjusting screw 301 to rotate, so that the moving block 302 moves on the adjusting screw 301. This causes the connecting rod 303 to rotate around the pivot and push the upper lying board 202, so that the upper lying board 202 rotates around the hinge axis, thereby making the upper body of the fitness person form a certain angle with the ground. This movement will work the upper pectoralis major and anterior deltoid muscles during bench press.

[0033] A locking knob 501 is threaded onto the bottom wall of the support frame 101. A sliding groove 502 is provided between the sliding frame 102 and the support frame 101. The sliding groove 502 is located at the lower end of the sliding frame 102 and is slidably connected to the locking knob 501. When the position of the sliding frame 102 needs to be adjusted according to the user's upper body length, the sliding frame 102 is pushed so that the sliding groove 502 slides with the locking knob 501. Then, the locking knob 501 is rotated to fix the position of the sliding frame 102.

[0034] The barbell bar 601 is equipped with an anti-slip sleeve 602, and barbell plates are fitted at both ends of the barbell bar 601. A clamp is fixedly connected to the barbell bar 601, and the clamp limits the movement of the barbell plates.

[0035] Working principle: When adjusting the position of the sliding frame 102 according to the user's upper body length, push the sliding frame 102 to make the sliding groove 502 slide against the locking knob 501. Then, rotate the locking knob 501 to fix the position of the sliding frame 102. The user then sits on the lower reclining board 201 and lies back on the upper reclining board 202. When adjusting the upper body angle, rotate the turntable to drive the adjusting screw 301 to rotate, causing the moving block 302 to move on the adjusting screw 301. This, in turn, drives the upper reclining board 202 to rotate around the hinge axis via the connecting rod 303, thus creating a certain angle between the user's upper body and the ground. This movement during bench press will work the upper pectoralis major and anterior deltoid muscles. The control module 103 has two symmetrical terminals 103-1 fixed inside, and connecting springs are installed in the two terminals. Springs make them abut against each other. When the insert block 401 is inserted into the control module 103, the insulating spacer 401-1 is located between the two terminals. The tightening strap 403 is fixed to the ankle with Velcro. When performing a bench press, first push the barbell bar 601 to disengage it from the limiting groove 406. If the barbell bar 601 cannot be effectively controlled during training, push outwards with the legs and pull out the insulating spacer of the insert block 401 through the connecting rope 402. This connects the two terminals and sends a signal to the controller to start the electric telescopic rod 404. The symmetrical electric telescopic rod 404 drives the support plate 405 to rise synchronously, causing the support plate 405 to push the barbell bar 601 upwards. The barbell bar 601 is always in contact with the front end of the support frame 101 during the rise. Then, when the barbell bar 601 rises to the limiting groove 406, it rolls into the limiting groove 406 by its own weight.
