Description

Technical Field

[0001] This utility model relates to the field of fitness equipment manufacturing technology, and in particular to a self-returning hook for suspending barbells in squat bench presses. Background Technology

[0002] Currently, squat bench press fitness equipment on the market generally achieves intensity training by loading barbells. That is, a barbell rack is set on the barbell column (usually a square tube column) of the main body of the equipment (squat bench press rack), and then the barbell is hung on it. Because the barbell hooks are fixed after the barbell rack is installed, the trainee needs to move forward a distance away from the rack after lifting the barbell to facilitate squat lifts or bench presses. This is because training directly under the fixed rack would obstruct the barbell's movement. After training, the trainee still needs to move back to the rack to put the barbell down, adding extra strain. This strain often exceeds the trainee's capacity. For example, if the trainee lacks the strength to hold the barbell and cannot move back in time, accidents can easily occur, causing injury (such as the barbell crushing or injuring the trainee, or falling and injuring them). Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a self-returning hook for barbell suspension in squat bench presses, so as to overcome the defects and shortcomings of existing similar products as described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a self-returning hook for barbell suspension in squat bench presses, including a triangular support and a hook arm. The lower end of the hook arm forms a hook, while the upper end of the hook arm forms a counterweight. A hook arm hinge is provided at the front end of the support. The support has a flat rear end face. A positioning pin and an L-shaped hook piece are welded to the rear end face of the support. The positioning pin is located on the vertical center line of the rear end face. One end of the L-shaped hook piece is welded to one side of the rear end face, and the other end faces horizontally to the other side of the rear end face. At the same time, a locking screw is provided on the back of the L-shaped hook piece. The hook arm is hinged to the front end of the support through the hook arm hinge. When the hook is unloaded, under the gravity of the counterweight, the hook will automatically rotate inward and adhere to the support. When the hook is loaded, the gravity of the load will overcome the inward rotational force caused by the counterweight and pull the hook down to the lowest point that the hook can reach.

[0005] Furthermore, a hook arm limiting shaft is also provided on the support. When the hook reaches its lowest point, the back of the hook arm abuts against the hook arm limiting shaft on the support.

[0006] The beneficial effects of this invention are as follows: Compared with existing fixed barbell racks, this self-returning hook for squat bench press barbell suspension has the function of self-rotating the arm under no-load conditions due to gravity. This eliminates the need for the trainee to move around while holding the barbell after lifting it, or to move back to the original position after the workout, thus reducing the trainee's burden and minimizing the risk of accidents. This self-returning hook for squat bench press barbell suspension is ingeniously designed, simple in structure, and easy to assemble and disassemble. Attached Figure Description

[0013] A self-returning hook for barbell suspension in squat bench presses, such as Figures 1 to 4 As shown, it includes a triangular support 1 and a hook arm 2. The lower end of the hook arm 2 forms a hook 2-2, while the upper end of the hook arm 2 forms a counterweight 2-1. A hook arm hinge 3 is provided at the front end of the support 1. The support 1 has a flat rear end face 1-1. A positioning pin 5 and an L-shaped hook piece 6 are welded onto the rear end face 1-1 of the support 1. The positioning pin 5 is located on the vertical center line of the rear end face 1-1. One end of the L-shaped hook piece 6 is welded to one side of the rear end face 1-1, and the other end is horizontal. On the other side of the rear end face 1-1, a locking screw 7 is provided on the back of the L-shaped hook piece 6; the hook arm is hinged to the front end of the support 1 through the hook arm hinge shaft 3. When the hook 2-2 is unloaded, under the gravity of the counterweight 2-1, the hook 2-2 will automatically rotate inward and adhere to the support 1; when the hook 2-2 is loaded, the gravity of the load will overcome the inward rotational force caused by the counterweight 2-1 on the hook 2-2, and pull the hook 2-2 down to the lowest point that the hook 2-2 can reach.

[0014] The self-returning hooks are installed in pairs (symmetrically installed left and right). When installing the self-returning hook onto the barbell column 8 (square tube column) of the squat bench press rack, first rotate the self-returning hook 90° vertically (clockwise or counterclockwise) so that the positioning pin 5 on the rear end face 1-1 of the self-returning hook's support 1 can be inserted into the pin hole on the barbell column 8 (the barbell column 8 has multiple pin holes of different heights for selection (to adjust the installation height of the self-returning hook)). Then, rotate the self-returning hook back to its original position (the hook 2-2 of the hook arm 2 facing downwards). At this point, the L-shaped hook 6 on the rear end face 1-1 of the support 1 precisely hooks onto the barbell column 8. Tightening the locking screw 7 secures the barbell column 8, preventing the L-shaped hook 6 from detaching from the barbell column 8 due to the left or right swing of the self-returning hook. Thus, the positioning pin 5 bears the weight of the self-returning hook and its load, positioning it at the selected height. The L-shaped hook 6 primarily counteracts the "forward tilting force" generated by the self-returning hook and its load, preventing the positioning pin 5 from dislodging from the pin hole in the barbell column 8. Through this installation structure (method), the self-returning hook can be easily and quickly installed, removed, and adjusted on the barbell column 8, while ensuring the stability and reliability of the self-returning hook installation.

[0015] like Figure 4 As shown, when the barbell 9 is hung on the hook 2-2 of the self-returning hook arm 2, the weight of the barbell 9 will overcome the inward rotational force caused by the counterweight 2-1 on the hook 2-2, and pull the hook 2-2 down to the lowest point that the hook 2-2 can reach.

[0016] A hook arm limiting shaft 4 is provided on the support 1. When the hook 2-2 reaches the lowest point, the back of the hook arm 2 abuts against the hook arm limiting shaft 4 on the support 1. The presence of the hook arm limiting shaft 4 can prevent the hook arm 2 from rotating excessively and the resulting swaying, thus eliminating risk factors.

[0017] When the trainee lifts the barbell 9 directly below the self-returning hook and barbell 9, the bar hook 2-2 is unloaded, as... Figure 3 As shown, under the gravity of the counterweight 2-1, the bar hook 2-2 will automatically rotate inward and adhere to the support 1 (rotating towards the barbell column 8), thus deviating from the direction of the trainee's lifting hands and making room for the barbell to move up and down. In this way, the trainee no longer needs to move around while holding the barbell to stagger the position or move back to place the barbell after the training, thereby reducing the trainee's burden and reducing the risk of accidents.

[0018] The above embodiments are only used to explain the present utility model and are not intended to limit the protection of the present utility model. Any non-substantial modifications made based on the essential solution of the present utility model shall fall within the protection scope of the present utility model.
