One end of the locking screw 683 is plugged with Knob 684.

Here’s how it works:

The support 1 is placed on the level ground. When training, the training personnel lies on the reclining chair 2, and then holds the handles of the barbell 4 with both hands, and then the training personnel bench press the barbell 4, so that the training personnel's arms can be trained. When the training personnel lies on the reclining chair, 2, the legs can be placed on the lower end of the presser foot bar 5, and then sit-ups can be done on the recliner 2 to train the trainer's waist, so that the barbell training device is not limited to training arm strength.

When the training personnel bench presses the barbell 4, the handle of the barbell 4 will drive the driven rod 63, so that the driven rod 63 slides along the surface of the side pad 62 and the second side pad 603, because the rack 64 is engaged with the driven tooth 65, and the tooth The bar 64 is located inside the driven rod 63, so when the driven rod 63 slides, it will drive the rack 64, causing the driven teeth 65 to rotate, so as to improve the sliding smoothness of the driven rod 63. The side of the driven rod 63 The rolling elements 66 provided on the wall will slide along the inner wall of the rolling groove to improve the smoothness of the driven rod 63 when sliding, so that the driven rod 63 will not get stuck when sliding, which will affect the training rhythm of the trainer. Through the column 3 left and right Side pads 62 and second side pads 603 are respectively provided on both sides, so that the side pads 62 and the second side pads 603 can prevent the driven rod 63 from tilting and improve the stability, so as to ensure that the driven rod 63 does not Side tilt will occur, so that when the trainer reaches exhaustion, the barbell 4 will not tilt. The barbell 4 is limited by the limiting structure 68 so that the barbell 4 will not collapse.

When the barbell 4 needs to be replaced, the trainer turns the knob 684 to rotate the locking screw 683. Since the locking screw 683 is threadedly connected to the driven rod 63 and the side plate 681, the locking screw 683 will rotate out of the driven rod when the locking screw 683 rotates. 63, then rotate out the side plate 681 and release the limit of the side plate 681. The side plate 681 will move downwards and drive the snap ring 682 to move downward. At this time, the opening width of the upper end of the snap ring 682 will increase, thus being larger than the barbell. 4 diameter of the handle, and then the training personnel can disassemble and replace it. After replacement, move the side plate 681 upward so that the snap ring 682 limits the 4 handle of the barbell, and then rotate the locking screw 683 to make the locking screw 683 penetrate the side plate 681 and connect with the barbell. The moving rod 63 is fixed to achieve the fixation of the side plate 681, thereby limiting and fixing the replaced barbell 4.

The utility model provides a sports multifunctional physical training device. By being provided with an anti-tilt device 6, when the training personnel bench press the barbell 4, the handle of the barbell 4 will drive the driven rod 63, so that the driven rod 63 moves along the side pad 62 and the third The surface of the two side pads 603 slides, and the side pads 62 and the second side pads 603 are respectively provided on the left and right sides of the column 3, so that the side pads 62 and the second side pads 603 will prevent the driven rod 63 from tilting and limit it, and lift it. The high stability prevents the driven rod 63 from tilting, and the limiting structure 68 limits the position of the barbell 4, thereby achieving the beneficial effect of preventing the barbell 4 from tilting or collapsing when the trainer fails. ; By providing the rolling element 66 and the driven tooth 65, when the driven rod 63 slides, it will drive the rolling element 66 to slide along the inner wall of the rolling groove to improve the sliding smoothness of the driven rod 63, and at the same time, it will also drive the rack 64 along the sliding groove. The surface of the driven tooth 65 moves to improve the smoothness and smoothness of the driven rod 63; by providing a limiting structure 68, the knob 684 is rotated to release the limit on the side plate 681, and then the side plate 681 is moved downwards Then the barbell 4 is disassembled and replaced. After replacement, the side plate 681 is moved upward, and then the locking screw 683 is used to limit the position, so that the snap ring 682 limits the position of the barbell 4, achieving the beneficial effect of convenient disassembly and replacement of the barbell 4.
