[0021] See also Figure 1-Figure 4 A self-returning dumbbell bench press auxiliary extension frame includes a bench press auxiliary frame 1, the bench press auxiliary frame 1 includes a fixed rod 101, a swing arm 102, a dumbbell bracket 103 and a spring thimble 104,
[0022] The fixed rod 101 is detachably mounted on the comprehensive training frame 2, a rotating shaft 105 is arranged at the bottom of the fixed rod 101, the swing arm 102 is sleeved on the rotating shaft 105 and is rotatably connected to the fixed rod 101, a spring ejector pin 104 is fixedly mounted on the fixed rod 101, a limiting guide rail 108 is arranged on the swing arm 102, a sliding rod 109 cooperating with the limiting guide rail 108 is arranged on the fixed rod 101, and the dumbbell bracket 103 is slidably mounted on the swing arm 102.
[0023] The comprehensive training frame 2 is provided with expansion holes. The bench press auxiliary frame 1 is inserted into different expansion holes through pins to adjust the height of the bench press auxiliary frame 1, which is convenient for quick installation and disassembly of the bench press auxiliary frame 1 and can adapt to trainees with different heights and arm lengths.
[0024] Furthermore, the limiting guide rail 108 is an arc-shaped guide rail with closed ends, and the sliding rod 109 is inserted into the limiting guide rail 108 and slidably connected thereto.
[0025] The limiting guide rail 108 and the slide bar 109 cooperate to limit the swing angle of the swing arm 102, thereby ensuring the stability and safety of the dumbbell during placement and use, avoiding the shaking or accidental falling of the dumbbell during the return process, and protecting the safety of the user.
[0026] Furthermore, the spring ejector pin 104 is located in front of the swing arm 102 , and the swing arm 102 may contact the spring ejector pin 104 during the swinging process along the limiting guide rail 108 .
[0027] The design of the spring thimble 104 and the swing arm 102 allows the dumbbell rack 103 to naturally rebound to its initial position after the dumbbell is removed. When the trainee takes the dumbbell, it can be quickly reset so as not to affect the trainee's bench press action. After the training is completed, the dumbbell is placed on the dumbbell rack 103, which can be reset and stored inside the comprehensive training frame 2 to avoid protruding outward and affecting the occupied space.
[0028] Furthermore, a guide rod 110 is provided on the side of the swing arm 102, and a sleeve 111 is provided on the back of the dumbbell bracket 103. The dumbbell bracket 103 slides with the guide rod 110 through the sleeve 111, and a threaded locking bolt 112 is provided on the sleeve 111.
[0029] Through the sliding cooperation between the sleeve 111 and the guide rod 110, the user can adjust the position of the dumbbell bracket 103 according to the personal shoulder width and arm length to achieve the best training posture, which increases the applicability and personalized adjustment ability of the equipment. The sleeve 111 is tightly connected to the guide rod 110, and the design of the locking bolt 112 can effectively lock the position of the dumbbell bracket 103 to prevent accidental movement during training, further enhancing the stability and safety of the entire equipment.
[0030] Furthermore, a handle 113 is fixedly mounted on the upper end surface of the sleeve 111 .
[0031] The convenience of the adjustment process is significantly improved by the handle 113. The user does not need to use additional tools, and can easily slide the sleeve 111 to the ideal position by simply holding the handle 113. It can also effectively prevent fingers from being pinched during the adjustment process, thereby improving safety.
[0032] Furthermore, a protective plate 106 is provided on the back side of the dumbbell bracket 103 .
[0033] The guard plate 106 is used to intercept the dumbbells, thereby increasing the stability of the dumbbells when placed, ensuring that the dumbbells are stably stored when not in use, and preventing the dumbbells from falling from the dumbbell bracket 103 due to inertia when placed.
[0034] Furthermore, a bracket 107 fixedly installed by bolts is provided at the upper end of the dumbbell bracket 103, and the bracket 107 is an arc-shaped structure.
[0035] The arc-structured bracket 107 can evenly distribute the weight of the dumbbells. Compared with the flat bracket 107, it can provide more stable support to prevent the dumbbells from rolling or sliding, especially when the user's movements are not precise enough when placing the dumbbells, safety can still be ensured. When the dumbbells are placed, the bracket 107 can effectively buffer the impact force generated by the collision between the dumbbells and the lower bracket, reduce the noise during placement, and create a quieter training environment.
[0036] First, ensure that the bench press auxiliary frame 1 has been correctly installed on the comprehensive training frame 2, all parts are installed in place and tightened without looseness, and place the dumbbells stably on the arc-shaped bracket 107. Before starting training, the trainee lies on his back under the bench press auxiliary frame 1 so that the dumbbell bracket 103 is located above his abdomen. Then, he grasps the dumbbell bar with both hands and drags the dumbbells toward the chest. The dumbbells slide out from above the bracket 107 under the action of tension, and the swing arm 102 hits the spring thimble 104. Under the resetting action of the spring thimble 104, the dumbbell bracket 103 rebounds to above the user's waist. Then, perform dumbbell bench press training. After the training reaches a single set of times, push the dumbbells to the highest point, then, with the shoulder joint as the center of the circle, keep the arms straight and swing forward to place the dumbbells on the bracket 107. After a short rest, perform the next set of training. After the training, check and ensure that all dumbbells have been correctly returned to their positions and the dumbbell bracket 103 is in its initial state.
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
