Through the resistance of the alignment horizontal block 30, The support frame 19 is blocked, so that when the support frame 19 continues to move upward, the first gear 21 can be driven to move upward along the surface of the third rack 22, so that the winding wheel 14 can pull the special-shaped bottom rod 17 to move upward through the wire rope 13, so that the movable guide rod 18 can squeeze the bottom front end of the receiving frame 20 and rotate upward, so that the barbell 3 can roll and reset to the rear end. When the support frame 19 moves up and down, the second rack 15 can be driven to move up and down along the surface of the second gear 28 at the same time, so that the first rack 6 can drive the flat cushion 4 to move up and down. At the same time, through the setting of the alignment cross block 30, the blocking plate 23 can be blocked from moving upward, so that the first gear 21 can be moved along the surface of the third rack 22, so that the first gear 21 can rotate;

[0037] When the second gear 28 rotates in the forward and reverse directions, it can drive the first rack 6 to move up and down respectively, so that the lying mat 4 can move up and down.

[0038] The sliding plate 7 is slidably inserted into the top of the supporting bottom plate 31, the first rack 6 is meshed with the second gear 28, the hydraulic cylinder 16 is symmetrically fixedly installed on both sides of the top of the positioning base 33, the second rack 15 is meshed with the second gear 28, the movable guide rod 18 is slidably inserted into the inside of the guide sleeve 24, the third rack 22 is meshed with the first gear 21, the interior of the supporting cavity 10 is set in a hollow state, and the blocking plate 23 slides through the top of the supporting cavity 10 and is connected to the top of the reset spring 12, and support shafts are installed on both sides of the receiving frame 20, and the support shafts are installed on the top of the supporting frame 19. At the rear of both sides, the blocking plate 23 is vertically aligned with the alignment cross block 30, movable grooves are opened on both sides of the support cavity 10, and the extension slide rod 11 is located inside the movable groove, the top front end of the receiving frame 20 is inclined at 45°, the bottom rear end of the receiving frame 20 is vertically aligned with the second through hole 26, the movable guide rod 18 is vertically aligned with the first through hole 25, an alignment hole is opened inside the top of the support bottom plate 31, there is an electrical connection between the button switch 27 and the hydraulic cylinder 16, the movable guide rod 18 is vertically aligned with the bottom front end of the receiving frame 20, and a square hole is opened inside the guide sleeve 24.

[0039] The working principle of embodiment 1 is as follows: when in use, the trainee can lie flat on the lying mat 4, hold the barbell 3 with both hands until the barbell 3 moves out from the inside of the supporting angle plate 29, and perform bench press strength training. When the trainee is exhausted, the trainee's legs can be synchronously contacted with the two button switches 27, so that the hydraulic cylinder 16 can be started. At this time, the piston rod inside the hydraulic cylinder 16 is connected to the bottom end of the supporting top frame 19, so that the supporting top frame 19 can be lifted upward, so that the supporting top frame 19 can drive the receiving frame 20 to contact with the barbell 3, thereby driving the barbell 3 to be lifted upward, avoiding the barbell 3 from causing crushing injuries to the trainee. At the same time, the barbell 3 can slide to the front along the top of the receiving frame 20. Through the setting of the receiving frame 20, it can be avoided The barbell 3 falls off, and when the support frame 19 moves upward, the second rack 15 can be driven to move upward along the surface of the second gear 28, and the first rack 6 is meshed with the second gear 28, so that when the second rack 15 moves upward, the first rack 6 can be driven to move downward, so that the flat mat 4 can drive the trainee to move downward, which is convenient for the trainee to open a gap with the barbell 3, and the sliding plate 7 slides inside the top of the support bottom plate 31, so that the flat mat 4 can be supported to move in a straight line, avoiding the flat mat 4 from tilting, completing the work of protecting the trainee, and then, when the support frame 19 moves upward, it can also drive the blocking plate 23 to contact the bottom end of the alignment cross block 30, and through the blocking of the alignment cross block 30, When the support frame 19 continuously moves upward, the blocking plate 23 can stop moving, so that the first gear 21 can move along the surface of the third rack 22, causing the first gear 21 to rotate. When the first gear 21 rotates, it can drive the winding wheel 14 to rotate, and when the winding wheel 14 rotates, the special-shaped bottom rod 17 can be pulled upward by the wire rope 13 to move upward, so that the movable guide rod 18 can pass through the guide sleeve 24 and insert into the bottom end of the support frame 19, so that when the movable guide rod 18 rises, it can push the bottom front end of the receiving frame 20 to move upward, and the receiving frame 20 is rotatably installed on the support frame 19 through the rear end, so that the front end of the receiving frame 20 can rotate upward, so that the receiving frame 20 can lift the barbell 3, and when the support frame 19 moves upward When it reaches the limit position, the inner bottom end of the supporting top frame 19 can be flush with the top end of the supporting angle plate 29, so that when the movable guide rod 18 rises to the limit position, it can drive the receiving frame 20 to tilt completely, causing the barbell 3 to slide toward the rear end along the surface of the receiving frame 20 and fall into the interior of the supporting angle plate 29, completing the resetting of the barbell 3. Subsequently, when the barbell 3 is reset, a reset button of the hydraulic cylinder 16 is installed at the rear end of the vertical frame 32, and the reset button can be operated to cause the supporting top frame 19 to move downward and reset. At this time, when the supporting top frame 19 moves downward, it can drive the first gear 21 to move downward along the surface of the third rack 22, so that the first gear 21 can rotate in the opposite direction and release the wire rope 13. At this time, the movable guide rod 18 will move downward and reset.At the same time, the receiving frame 20 will also rotate downward until it is flush with the inner bottom end of the supporting top frame 19, completing the reset of the receiving frame 20. Moreover, when the supporting top frame 19 moves downward, it can also drive the second rack 15 to move downward along the surface of the second gear 28, thereby driving the first rack 6 and the flat-lying mat 4 to move upward and reset, so that the trainee can lie flat on the flat-lying mat 4 again to complete the work. When the device is in use, the second through hole 26 is set to allow the bottom rear of the receiving frame 20 to rotate downward, so that the front end of the receiving frame 20 can rotate upward, so that the barbell 3 can slide toward the rear end along the surface of the receiving frame 20. At the same time, the support point of the receiving frame 20 is located at the rear of the receiving frame 20, so that when the receiving frame 20 loses the extrusion of the movable guide rod 18, the receiving frame 20 will rotate downward, so that the receiving frame 20 can be reset.

[0040] Example 2

[0041] On the basis of Example 1, Figure 8 As shown, the flat-lying pad 4 further includes a sponge pad 36 and air holes 37 . The air holes 37 are equidistantly arranged inside the sponge pad 36 . The sponge pad 36 is fixedly mounted at the top rear of the flat-lying pad 4 .

[0042] When implementing this embodiment, the sponge pad 36 is installed at the top rear of the flat pad 4, so that the trainee's head can be located above the sponge pad 36, and at the same time, the comfort of the trainee's head can be improved. In addition, the air holes 37 are symmetrically opened inside the sponge pad 36, so that the air permeability inside the sponge pad 36 can be improved, avoiding excessive accumulation of sweat at the bottom of the trainee's head, thereby completing the work.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
