[0002] In the current fitness equipment market, dumbbells are a very popular strength training tool, and the optimization of their design and functions has always been the focus of attention of manufacturers and fitness enthusiasts. Although there are many types of dumbbells on the market, including fixed weight dumbbells and adjustable dumbbells, they still face some common problems.

[0003] Traditional adjustable dumbbells often rely on a simple nut fixing method to fix the dumbbell plates. However, during high-intensity exercise, due to continuous vibration and impact, the fixing nuts are prone to loosening, causing the dumbbell plates to accidentally fall off, which not only affects the exercise effect but also may cause safety hazards. Users need to frequently tighten the fixing nuts, which increases the cumbersomeness of dumbbell plate installation. Therefore, a dumbbell that is easy to install is needed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 4 , a dumbbell that is easy to install, comprising a dumbbell bar 1, a dumbbell plate 2 and a fixing nut 3, wherein the fixing nut 3 is provided with an anti-slip mechanism 4;

[0022] External threads are provided at both ends of the dumbbell rod 1, the dumbbell plates 2 are installed on the dumbbell rod 1 and are slidably connected thereto, the fixing nuts 3 are installed at both ends of the dumbbell rod 1 and are threadedly connected thereto, the anti-slip mechanism 4 includes a locking column 401, a connecting rod 402, a spring 404 and an anti-slip plug 403, the locking column 401 is movably installed on the upper end surface of the connecting rod 402, the anti-slip plug 403 is fixedly installed on the lower end surface of the connecting rod 402 away from the locking column 401, a rotating shaft 4022 is provided at the center of the connecting rod 402, and the connecting rod 402 and the fixing nut 3 are elastically rotatably connected through the rotating shaft 4022 and the spring 404.

[0023] Furthermore, a slide rail 4021 is disposed at the upper end of the connecting rod 402 , a slider 4012 cooperating with the slide rail 4021 is disposed at the bottom of the locking column 401 , and the locking column 401 and the connecting rod 402 are slidably connected through the slider 4012 cooperating with the slide rail 4021 .

[0024] The slidingly connected locking column 401 can slide along the slide rail 4021, thereby driving the limit block 4011 to slide, so that it interlocks with the inner wall of the fixing nut 3, or releases the interlocking, thereby changing the rotation resistance of the locking bolt.

[0025] Furthermore, a limiting block 4011 is provided on the side of the locking column 401 , and a sliding groove 301 cooperating with the locking column 401 is provided on the fixing nut 3 .

[0026] When the locking column 401 is pressed, the locking column 401 is pushed, and the limit block 4011 is stuck on the lower end surface of the slide groove 301, thereby fixing the locking column 401 and separating the anti-skid plug 403 from the threaded surface of the dumbbell rod 1, reducing the rotation resistance of the fixing nut 3, and facilitating the installation and removal of the dumbbell plate 2. When the locking column 401 is pulled back, the limit block 4011 can slide from the slide groove 301 into the slide groove 301, so that the spring 404 squeezes the connecting rod 402, and the anti-skid plug 403 squeezes the outer end surface of the threaded rod under the action of the lever, thereby increasing the fixing resistance of the fixing nut 3 and preventing the fixing nut 3 from loosening.

[0027] Furthermore, an interference fit rubber plug 4031 is provided at the bottom of the anti-slip plug 403 .

[0028] The rubber plug 4031 has good elasticity and can fully fill the gap in the threaded door, increase the friction between the fixing nut 3 and the dumbbell rod 1, thereby improving the anti-loosening effect, and the rubber plug 4031 structure with interference connection is convenient for replacement after it is worn.

[0029] Furthermore, a rubber ring 201 is provided on the side end surface of the dumbbell plate 2 .

[0030] The rubber ring 201 is used to buffer the dumbbell pieces 2, thereby reducing the noise generated by the dumbbell pieces 2 colliding with each other during installation, and at the same time reducing the impact on the dumbbell pieces 2, thereby increasing the service life of the dumbbell pieces 2.

[0031] Furthermore, anti-slip grooves 101 are provided on the surfaces of the dumbbell bar 1 and the fixing nut 3 .

[0032] The anti-skid groove 101 increases the resistance of the dumbbell bar 1 and the fixing nut 3, so that the knob fixing nut 3 does not slip when being turned, thereby preventing the knob fixing nut 3 from being tightened.

[0033] Furthermore, the dumbbell plate 2 is a regular hexagonal structure.

[0034] When the dumbbell plate 2 with a regular hexagonal structure is placed on the ground, it will not roll, thereby improving the stability of the dumbbell.

[0035] When the dumbbell is in use, the dumbbell piece 2 is slid to the appropriate position of the dumbbell rod 1, the rubber ring 201 of the dumbbell piece 2 faces inward to reduce the impact noise, and the locking column 401 is pressed. This will push the locking column 401 through the cooperation of the slider 4012 and the slide rail 4021, so that the limit block 4011 is stuck in the lower end surface of the slide groove 301 on the fixing nut 3. At this time, the anti-skid plug 403 is separated from the threaded surface of the dumbbell rod 1, reducing the rotation resistance of the fixing nut 3, making it convenient for the user to easily rotate the fixing nut 3 to install or remove the dumbbell piece 2. After completing the installation of the dumbbell piece 2 and tightening the fixing nut 3, the locking column 401 is reversed, and the limit block 4011 slides to the slide groove 301. Under the resetting action of the spring 404, the locking column 401 rotates upward, and the anti-skid plug 403 immediately presses the outer end surface of the threaded rod under the action of the lever, thereby increasing the fixing resistance of the fixing nut 3 and effectively preventing the fixing nut 3 from accidentally loosening during use.

[0036] 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.
