Description

Technical Field

[0001] The utility model relates to the technical field of sports training appliances, in particular to a squat rack. Background Art

[0002] In physical exercise, squatting is a common way of physical exercise. In order to achieve safe squatting exercise, some special auxiliary appliances for squatting will be used, such as a squat rack. The squat rack is a fixed frame structure, and a barbell for squatting is arranged on the frame. The user can do squatting and standing up movements by shouldering the barbell, so as to carry out the exercise of the leg muscle group. Therefore, in physical exercise, the use of a squat rack is indispensable. Since the heights and body types of users are different, different requirements are also put forward for the height position setting of the barbell during exercise. Therefore, in order to facilitate the squat rack to be conveniently adapted to users of different body types, there is a certain need for the function of adjusting the height.

[0003] A prior art sports training squat rack with the publication number of CN219090970U includes a training rack, a barbell and a support rod. The support rod is arranged on the front of the training rack, and the barbell is clamped on both sides of the support rod. A hook located above the support rod is slidably connected to the upper side of the training rack. A chute is formed on the front side wall of the training rack, and a sliding frame located on the side wall of the training rack is slidably connected in the chute. A fixed clamp is arranged on the front of the sliding frame, and the support rod and the fixed clamp are clamped. A buffer rack located at the bottom of the sliding frame is arranged below the training rack. Looking at its overall structure, its structure can realize the adjustment and control of the height position of the barbell through the cooperation of structures such as sliders, chutes, limit holes, and insertion rods. However, combined with its structure, during the adjustment operation, the barbell needs to be removed first, and then the sliding frames on the left and right sides are adjusted separately and fixed correspondingly. After fixing, the barbell is placed on the structure before training can be carried out. Such an adjustment method has cumbersome steps, is very time-consuming and laborious in operation, lacks convenience in adjustment work, and also requires the assistance of fixed personnel to carry out the adjustment during adjustment, resulting in limitations in use for some users with insufficient height during adjustment.

[0028] Refer to Figures 1-4, An embodiment provided by the present utility model: A squat rack, comprising a fixed frame body 1. The fixed frame body 1 includes two support seats 2, two support frames 3 and a cross frame 4. The two support frames 3 are respectively fixed on the tops of the two support seats 2, and the cross frame 4 is fixed between the two support frames 3. The cross frame 4 is located at a position close to the top on the support frames 3. The support seats 2, the support frames 3 and the cross frame 4 are welded together to form a stable structure of the fixed frame body 1. Grooves 7 are provided on both of the two support frames 3, and screw rods 8 are rotatably connected in the two grooves 7. The positions where the screw rods 8 are in contact with the inner walls of the grooves 7 are positioned and installed through bearings. Lifting blocks 9 are threadedly sleeved on both of the two screw rods 8. The lifting blocks 9 are nested and slid on the outer sides of the support frames 3. A fixing groove 10 is provided on one of the support frames 3. A first bevel gear 11 is fixedly connected to the bottom end of one of the screw rods 8 and located in the fixing groove 10. A second bevel gear 12 is meshed with the first bevel gear 11. A rotating wheel 14 is fixedly connected to the central axis of the second bevel gear 12. An operating handle rod 15 is provided on the rotating wheel 14. A synchronization mechanism is provided at positions corresponding to the two screw rods 8 inside the fixed frame body 1. The synchronization mechanism can enable the two screw rods 8 to rotate synchronously. In this way, cooperating with the whole structure can drive the two lifting blocks 9 to lift synchronously, so as to conveniently adjust the position height of the structure, which can not only ensure uniform load bearing on both sides of the structure, but also realize balanced and stable lifting adjustment on both sides. Placing frames 18 are fixedly connected to both of the two lifting blocks 9. Placing grooves 19 are provided on both of the two placing frames 18. A squat barbell 21 is provided in the two placing grooves 19.

[0029] Bottom pads 5 are provided at the bottoms of the two support seats 2. Both of the two bottom pads 5 are made of rubber. The bottom pads 5 can be made of anti-slip rubber, which can not only realize the stable positioning of the whole structure, but also make the structure wear-resistant, durable and corrosion-resistant, and can reduce the wear of the support seats 2.

[0030] Reinforcing ribs 6 are fixedly connected correspondingly between the two support seats 2 and the two support frames 3. The arrangement of the reinforcing ribs 6 can enhance the stability of the structure of the support frames 3.

[0031] A receiving groove 13 is provided on one side of the outer surface of one of the support frames 3. The rotating wheel 14 is nested in the receiving groove 13. The arrangement of the receiving groove 13 can make the rotating wheel 14 an internal structure, which can play a safety protection effect on the operating part of the whole structure and avoid the structure being accidentally touched.

[0032] A storage groove 16 is provided on one side of the outer surface of the rotating wheel 14, and a fixing block 17 is fixedly connected to one side of the inner wall of the storage groove 16. One end of the operating handle rod 15 is rotatably connected to the fixing block 17. One end of the operating handle rod 15 is located near the edge of the rotating wheel 14, so that the rotating wheel 14 can be driven to rotate by grasping the operating handle rod 15 and rotating it around the center of the rotating wheel 14. The setting of the storage groove 16 can ensure stable storage of the operating handle rod 15 when it is not in use, thereby preventing the structure from being accidentally touched and operated.

[0033] The inner walls of the two placement grooves 19 are both provided with protective pads 20, and the two protective pads 20 are both made of rubber. The rubber protective pads 20 are wear-resistant and durable, and can reduce the wear between the squat barbell 21 and the placement rack 18 after being placed, thereby achieving a stable protective effect.

[0034] The synchronization mechanism includes an inner groove 22 arranged in the cross frame 4, both ends of the inner groove 22 extend into the two support frames 3, the outer surfaces of the two screw rods 8 and located in the inner groove 22 are nested and fixedly connected with sprockets 23, and the two sprockets 23 are connected by a chain 24. When one of the screw rods 8 rotates, the other screw rod 8 can rotate synchronously through the cooperation of the sprocket 23 and the chain 24, thereby allowing the two lifting blocks 9 to adjust the lifting synchronously to ensure the stability of the structural height adjustment.

[0035] Working principle: When using the squat rack, when the position height of the squat barbell 21 needs to be adjusted, grasp the operating handle 15 and revolve it around the center position of the rotating wheel 14, which can drive the rotating wheel 14 to rotate, and the rotating wheel 14 drives the bevel gear 2 12 to rotate, the bevel gear 2 12 drives the bevel gear 1 11 to rotate, the bevel gear 1 11 drives the screw 8 to rotate, and the screw 8 drives the lifting block 9 to rise and fall. Through the setting of the synchronization mechanism, the lifting blocks 9 on both sides can be lifted and lowered synchronously, the two lifting blocks 9 drive the two placement racks 18 to rise and fall synchronously, and the two placement racks 18 drive the squat barbell 21 to rise and fall smoothly, so that its position height can be stably adjusted to meet the training needs of users of different heights.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
