It usually includes a lying board, a barbell rack, a barbell and matching barbell plates. The main purpose of this device is to help athletes or fitness enthusiasts perform bench press exercises more safely and efficiently.

[0003] When doing bench press training, the trainee needs to lie flat on the lying board and push the barbell with both hands to achieve the purpose of physical exercise. The trainee will perform the bench press of the barbell in stages according to his own training needs, so as to ensure the effect of the bench press training. After each stage of training, the barbell is still on the trainee's body. Some trainees will not be able to put the barbell back to its original position safely due to muscle fatigue. Without the help of outsiders, the trainee will be pressed on the lying board by the barbell and cannot move. In the existing bench press strength training device for sports training, the barbell used by the trainee must be placed on the barbell rack after the bench press, which reduces the use efficiency of the bench press training device. Some trainees cannot put the barbell back on the barbell rack after long-term training, which reduces the safety of the training device. In addition, the training device with a lifting function will cause secondary injuries to the trainee due to the imbalance of the barbell during the lifting process. Therefore, it is urgent to design a bench press strength training device for sports training to solve the above problems. Summary of the invention

When the training device is in use, the position of the barbell body 12 can be suspended at any time, so that it is convenient for people to walk out of the lying board 1 and then to train next time, which not only ensures the training effect of the trainees, but also ensures the safety of the trainees. In addition, the training guides the moving direction of the barbell body 12, avoids the position displacement of the barbell body 12 during the lifting process, and ensures the safety and efficiency of the barbell body 12 during use.

[0032] Furthermore, the movable base frame 22 is in a "T" shape as a whole. The movable base frame 22 slides on the surface of the first guide rail 2 through the first slider 21. A knob is provided on one side of the screw rod 23. The screw rod 23 is rotated by the knob. The screw rod 23 drives the movable base frame 22 to slide on the surface of the first guide rail 2 by rotation. The movable base frame 22 drives the first telescopic rod 24 and the connecting ring 25 to slide during the sliding process. The first telescopic rod 24 and the connecting ring 25 can be moved to the area where the trainee bench presses, so that the trainee can observe whether the trainee's bench press is standard by observing the first telescopic rod 24 during the use of the connecting ring 25. At the same time, the two groups of first telescopic rods 24 ensure the stability of the barbell body 12 during the lifting process.

[0033] Furthermore, two groups of first telescopic rods 24 are provided, and the first telescopic rods 24 are symmetrically distributed on the movable base frame 22. The barbell body 12 moves on the piston rod of the first telescopic rod 24 through the connecting ring 25. The first telescopic rod 24 drives the barbell body 12 to rotate synchronously on the movable base frame 22. The first telescopic rod 24 increases the moving range of the barbell body 12 during use by rotating. Barbell supporting legs are provided on the surface of the barbell rack 11. The barbell rack 11 supports the barbell body 12 through the barbell supporting legs. The first telescopic rod 24 can rotate the barbell body 12 to the surface of the barbell rack 11 for support through the connecting ring 25.

[0034] Furthermore, two groups of movable rods 3 and support rods 31 are provided, and the two groups of movable rods 3 and support rods 31 are symmetrically distributed on the top of the barbell rack 11. The movable rod 3 drives the second pulley 33 and the third pulley 34 to move on the top of the barbell rack 11, and the second pulley 33 and the third pulley 34 are symmetrically distributed on the top of the barbell rack 11. The cable 36 is simultaneously connected to the surfaces of the first pulley 32, the second pulley 33, the third pulley 34 and the fourth pulley 35. The length of the cable 36 is constant. When the positions of the second pulley 33 and the third pulley 34 change, the height and position of the barbell body 12 directly above the lying board 1 will also change accordingly, and the cable 36 is always connected to the surfaces of the first pulley 32, the second pulley 33, the third pulley 34 and the fourth pulley 35, thereby ensuring the support of the barbell body 12.

[0035] Furthermore, one end of the cable 36 away from the winding wheel 38 is fixedly connected to the middle part of the barbell body 12, and the cable 36 cooperates with the two sets of first telescopic rods 24 to ensure the stability of the barbell body 12 during the lifting process. The cable 36 is overall triangular in shape on the first pulley 32, the second pulley 33 and the third pulley 34, and the cable 36 is overall "L" in shape on the third pulley 34, the winding wheel 38 and the fourth pulley 35, and the cable 36 is also overall triangular in shape on the first pulley 32, the third pulley 34 and the fourth pulley 35. The shape of the cable 36 is affected by the positions of the first pulley 32, the second pulley 33, the third pulley 34 and the fourth pulley 35, and the overall shape of the cable 36 determines the height of the barbell body 12 directly above the lying board 1.

[0036] Furthermore, the motor 37 drives the winding wheel 38 to rotate via the output shaft, and the winding wheel 38 winds the cable 36 around the surface of the winding wheel 38 by rotating. The motor 37 and the trigger rod 39 are connected by a line, and the trigger button 310 drives the motor 37 to start via the trigger rod 39. There are two groups of trigger buttons 310 and they are located on both sides of the trigger rod 39. The trainee needs to clamp the trigger buttons 310 with both legs to trigger the trigger rod 39 to avoid accidental touch, thereby driving the output shaft of the motor 37 to rotate.

[0037] Furthermore, a circular hole is opened on the surface of the lifting block 42, and the lifting block 42 slides and rises and falls on the surface of the vertical rod 4 through the circular hole. During the lifting process, the lifting block 42 drives the movable rod 3 to rotate on the barbell rack 11 through the support rod 31. The elastic force of the first spring 41 directly acts on the surface of the lifting block 42. The lifting block 42 limits the angle of the movable rod 3 and the support rod 31 under the action of the elastic force. When the second pulley 33 and the third pulley 34 on the movable rod 3 are under the pressure of weight, the movable rod 3 and the support rod 31 will drive the lifting block 42 to slide and descend on the surface of the vertical rod 4 while the angle changes.

[0038] Furthermore, a guide groove is provided on the surface of the guide cylinder 43, and the second spring 44 is fixedly connected to the guide groove of the guide cylinder 43. The limit rod 45 slides on the guide groove of the guide cylinder 43, and the limit rod 45 drives the connecting rod 46 to slide synchronously. The elastic force of the second spring 44 acts on the connecting rod 46 through the limit rod 45, and the connecting rod 46 then acts on the adjusting rod 51 through the trigger rod 39, thereby limiting the height of the connecting plate 52 and the pillow pad 14. At this time, the height of the pillow pad 14 is higher than the height of the support pad 13. When the pillow pad 14 is subjected to pressure, the pillow pad 14 will drop to the same horizontal plane as the support pad 13. A guide groove is provided on the surface of the transverse rod 49, and the connecting rod 46 slides on the guide groove of the transverse rod 49, so that no matter what height the guide cylinder 43 and the limit rod 45 are at, the transverse rod 49 is always connected through the connecting rod 46, the guide cylinder 43 and the limit rod 45 and the lifting block 42.

[0039] Furthermore, two groups of transverse rods 49 and positioning rods 5 are provided, and multiple groups of limiting holes are provided on the surface of the positioning rod 5. The limiting rod 45 is inserted into the limiting holes of the positioning rod 5. The positioning rod 5 limits the position of the guide cylinder 43 and the limiting rod 45 through the transverse rod 49. The guide cylinder 43 limits the angle of the movable rod 3 and the support rod 31 through the lifting block 42. The change in the angle of the movable rod 3 directly changes the position of the second pulley 33 and the third pulley 34, and the second pulley 33 and the third pulley 34 limit the horizontal height of the barbell body 12 directly above the lying board 1 through the cable 36.

[0040] Furthermore, the connecting plate 52 and the pillow pad 14 slide and rise and fall on the barbell rack 11 through the telescopic end of the lifting block 42, and the transverse rod 49 slides laterally on the surface of the barbell rack 11 through the connecting rod 46 and the second guide rail 47. The connecting plate 52 drives the transverse rod 49 to slide through the adjusting rod 51 during the lifting process. During the sliding process, the transverse rod 49 drives the limiting rod 45 to slide to the limiting hole inserted into the positioning rod 5 through the connecting rod 46. The transverse rod 49 maintains a connection relationship with the connecting rod 46 at all times through the guide groove. When the trainee needs to withdraw from the bench press training, it only needs to limit the position of the lifting block 42 on the vertical rod 4.

[0041] Working principle: During bench press training, the trainee's head will drive the connecting plate 52 to descend through the pillow 14, and the connecting plate 52 will drive the transverse rod 49 to move transversely on the surface of the barbell rack 11 through the adjusting rod 51. The transverse rod 49 slides on the surface of the barbell rack 11 through the second guide rail 47 and the second slider 48. The transverse rod 49 drives the limiting rod 45 to squeeze the second spring 44 through the connecting rod 46, so that the limiting rod 45 falls off the limiting hole of the positioning rod 5. At this time, the barbell body 12 on the connecting rod 46 is not restricted by the cable 36, and normal bench press training can be performed. In the process of bench press the barbell body 12, the cable 36 will drive the movable rod 3 and the support rod 31 to rotate through the second pulley 33 and the third pulley 34, thereby ensuring the use length of the cable 36. After the bench press training is completed, the trainee only needs to To lift the head from the pillow 14, the elastic force of the second spring 44 will drive the limit rod 45 to move in the direction of the positioning rod 5, and make the limit rod 45 inserted in the limit hole of the positioning rod 5. The positioning rod 5 limits the position of the lifting block 42 on the surface of the vertical rod 4 through the guide cylinder 43 and the limit rod 45. The lifting block 42 limits the angle of the movable rod 3 and the support rod 31, and the second pulley 33 and the third pulley 34 on the movable rod 3 limit the height of the barbell body 12 directly above the lying board 1 through the cable 36, thereby preventing the trainer from sending the barbell body 12 back to the barbell rack 11, and further preventing the barbell body 12 from falling on the staff, thereby ensuring the safety of the staff. At the same time, by raising the head and standing up, the barbell body 12 can be directly limited to a certain position, which greatly improves the efficiency of the trainer's bench press training.

[0042] When the trainee is exhausted, the trainee can clamp the trigger button 310 with his legs. The trigger button 310 causes the output shaft of the motor 37 to start rotating through the trigger rod 39. The motor 37 drives the winding wheel 38 to rotate through the output shaft, thereby winding the cable 36 around the surface of the winding wheel 38. The cable 36 then drives the barbell body 12 to rise just above the lying board 1. The first telescopic rod 24 and the connecting ring 25 at the bottom of the barbell body 12 ensure the stability of the barbell body 12 during the lifting process, and avoid the barbell body 12 slipping during the lifting process, thereby causing secondary injuries to the trainee. At the same time, it avoids the trainee from being unable to lift the barbell body 12, and ensures that the trainee can leave the training device normally after the training is completed.
