[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: a safety support assembly for weightlifting, comprising a left support column 1 and a right support column 2, wherein the left support column 1 and the right support column 2 are both provided with a square lifting slot 11, and a stepper motor 3 is detachably mounted on the upper end of the left support column 1, and the output shaft of the stepper motor 3 movably passes through the left support column 1, and a screw rod 31 is fixedly connected to the lower end of the output shaft;

[0018] The square lifting grooves 11 are each provided with a square block 4, the screw rods 31 are threadedly connected to the corresponding square blocks 4, and the lifting shafts 5 are fixedly connected between the square blocks 4, and the lower ends of the lifting shafts 5 are connected to barbell rods 7 through two symmetrically arranged safety belts 6.

[0019] Furthermore, guide grooves 12 are provided on the opposite side walls of the left support column 1 and the right support column 2. Both ends of the lifting shaft 5 pass through the guide grooves 12 and are connected to the square block 4 accordingly. The lifting shaft 5 is located in the guide grooves 12 and moves up and down to adjust the position of the barbell bar 7 to meet the requirements of different groups of people.

[0020] Furthermore, corresponding grooves 71 are provided on the barbell bar 7 and the lifting shaft 5, and the two ends of the safety belt 6 pass through the grooves 71. The lifting shaft 5 is connected to the barbell bar 7 through the safety belt 6 to achieve the insurance function of the barbell bar 7, so as to prevent the trainee from losing strength during bench press training and causing the barbell bar 7 to fall out of the hand and crush the user.

[0021] Further, the barbell bar 7 is arranged in contact with the side walls of the left support column 1 and the right support column 2. At this time, the two safety belts 6 are in an inclined straightened state, and the safety belts 6 support the barbell bar 7.

[0022] Further, a lying board 8 is provided between the left supporting column 1 and the right supporting column 2, and a supporting seat 9 is provided at the lower end of the other side of the lying board 8. The lying board 8 is used for the trainee to perform lying training.

[0023] Specifically, the trainee lies on the reclining board 8, and the training instructor starts the stepping motor 3 to drive the screw rod 31 to rotate according to the trainee's body shape, thereby driving the square block 4 and the lifting shaft 5 to rise and fall, so as to adjust the height of the barbell bar 7, so that the barbell bar 7 is flush with the trainee's chest, so that the trainee can train according to the standard movements;

[0024] Then the trainee presses the barbell bar 7 with both hands, driving the barbell bar 7 to move up and down, that is, the trainee loses strength, the barbell bar 7 falls out of hand, and the safety belt 6 will not cause pressure injury to the barbell bar 7, thereby ensuring safe training.
