[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of 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.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] The utility model provides a dumbbell plate adjustment handle, comprising: a handle 1;

[0029] A dumbbell plate support rod 2 is embedded and installed on the left and right sides of the handle 1. When using the dumbbell for exercise, the dumbbell can be picked up by holding the handle 1, and the handle 1 can also support the dumbbell plate support rod 2, and the dumbbell plate support rod 2 can support and fix the dumbbell plate 4; a lower support plate 3 is welded to the bottom of one side of the dumbbell plate support rod 2, and when the dumbbell needs to be placed on the ground, the plane at the bottom of the lower support plate 3 can be in contact with the ground, thereby preventing the dumbbell from rolling around on the ground; a dumbbell plate 4 is slidably installed on the outer side of the dumbbell plate support rod 2, and the dumbbell plate 4 is used to counterweight the dumbbell. The more dumbbell plates 4 are installed, the heavier the dumbbell is. When installing the dumbbell plates 4, you only need to remove the dumbbell plate support rod 2 from the handle 1 first, and then adjust the When the section rod 6 is pressed toward the inner side of the dumbbell plate support rod 2, the positioning column 5 will be retracted into the dumbbell plate support rod 2, so the dumbbell plate 4 can be sleeved on the outer side of the dumbbell plate support rod 2; two positioning columns 5 are slidably installed inside one side of the dumbbell plate support rod 2, and the positioning column 5 is used to fix the position of the dumbbell plate support rod 2. After the dumbbell plate support rod 2 is installed in place, the positioning column 5 will extend outward and be embedded in the annular groove outside the cylindrical groove in the handle 1, thereby limiting the dumbbell plate support rod 2 from sliding left and right inside the handle 1. When the dumbbell plate support rod 2 needs to be disassembled, it is only necessary to press the adjusting rod 6 toward the inner side of the dumbbell plate support rod 2 to make the positioning column 5 retract into the dumbbell plate support rod 2, so the dumbbell plate support can be removed. The support rod 2 is pulled out from the cylindrical groove in the handle 1; an adjusting rod 6 is also slidably installed inside the dumbbell support rod 2, and the position of the piston 9 can be adjusted when the adjusting rod 6 slides. When the adjusting rod 6 is pressed toward the inside of the dumbbell support rod 2, the piston 9 will also slide toward the position of the positioning column 5. During this process, the air in the cylindrical cavity where the piston 9 is located will enter the cylindrical cavity where the piston plate at one end of the positioning column 5 is located, thereby pushing the positioning column 5 to slide toward the inside of the dumbbell support rod 2. At this time, the positioning column 5 will be completely hidden in the dumbbell support rod 2, thereby facilitating the installation or removal of the dumbbell support rod 2, and when the adjusting rod 6 is pressed toward the inside of the dumbbell support rod 2, the push plate 7 The spring 8 on the right side will also be compressed, so after the adjusting rod 6 is loosened, the spring 8 will push the push plate 7 and the adjusting rod 6 to slide toward the outside of the dumbbell support rod 2. At this time, the air pressure in the cylindrical cavity where the piston 9 is located will be reduced, so the air in the cylindrical cavity where the piston plate at one end of the positioning column 5 is located will be sucked into its interior, which will also cause the positioning column 5 to slide toward the outside and extend outward, thereby locking the position of the dumbbell support rod 2; a push plate 7 is provided on the outside of the adjusting rod 6, and when the adjusting rod 6 is pressed toward the inside of the dumbbell support rod 2, the spring 8 on the right side of the push plate 7 will also be compressed, so after the adjusting rod 6 is loosened, the spring 8 will push the push plate 7 and the adjusting rod 6 to slide toward the outside of the dumbbell support rod 2;A spring 8 is provided on one side of the push plate 7. When the adjustment rod 6 is pressed toward the inside of the dumbbell support rod 2, the spring 8 on the right side of the push plate 7 will also be compressed. Therefore, after the adjustment rod 6 is released, the spring 8 will push the push plate 7 and the adjustment rod 6 to slide toward the outside of the dumbbell support rod 2; a piston 9 is also fixed at one end of the adjustment rod 6. When the piston 9 slides left and right, the position of the positioning column 5 can be adjusted by the change of air pressure. ;

[0030] In the present disclosure, Figure 5 and Figure 6 As shown, the dumbbell plate support rod 2 is also provided with two cylindrical cavities with an inner diameter equal to the outer diameter of the piston 9, and the cylindrical cavities are connected with the cavity installed with the piston plate at one end of the positioning column 5. When the piston 9 slides left and right, the air pressure of the cylindrical cavity in which it slides can be adjusted. Because this cylindrical cavity is also connected with the cavity installed with the piston plate at one end of the positioning column 5, the position of the positioning column 5 can be adjusted by changing the air pressure.

[0031] In the present disclosure, Figure 1-Figure 5 As shown, a cylindrical groove with an inner diameter equal to the outer diameter of the dumbbell plate support rod 2 is provided on both sides of the handle 1, and the lower supporting plate 3 is an L-shaped plate. The handle 1 can support the dumbbell plate support rod 2 by relying on the cylindrical grooves on both sides thereof. When the dumbbell needs to be placed on the ground, the plane at the bottom of the lower supporting plate 3 can be in contact with the ground, thereby preventing the dumbbell from rolling around on the ground.

[0032] In the present disclosure, Figure 5 As shown, the spring 8 can push the push plate 7 and the adjusting rod 6 to slide toward the outside of the dumbbell support rod 2, and when the adjusting rod 6 slides to the outermost side, the air pressure in the cylindrical cavity where the piston 9 is located will decrease, and the positioning column 5 will also extend outward. After the adjusting rod 6 is released, the spring 8 will push the push plate 7 and the adjusting rod 6 to slide toward the outside of the dumbbell support rod 2. At this time, the air pressure in the cylindrical cavity where the piston 9 is located will decrease, so the air in the cylindrical cavity where the piston plate at one end of the positioning column 5 is located will be sucked into it, which will cause the positioning column 5 to slide toward the outside and extend outward, thereby locking the position of the dumbbell support rod 2.

[0033] In the present disclosure, Figure 5 and Figure 6 As shown, the outer wall of the dumbbell plate support rod 2 is provided with two circular holes with an inner diameter equal to the outer diameter of the main part of the positioning column 5. A piston plate is also provided at one end of the positioning column 5, and the outer wall of the piston plate is in close contact with the inner wall of the cylindrical cavity inside the dumbbell plate support rod 2. The cavity where the piston plate at one end of the positioning column 5 is located is connected with the cavity where the piston 9 is located, so the positioning column 5 can be driven to slide up and down by relying on changes in air pressure, thereby locking or unlocking the position of the dumbbell plate support rod 2.

[0034] In the present disclosure, Figure 2-Figure 5 As shown, four annular grooves are equidistantly arranged on the outside of the two cylindrical grooves in the handle 1, and the width of the annular grooves is equal to the outer diameter of the positioning column 5, and the spacing between the center positions of adjacent annular grooves is equal to the thickness of the dumbbell plate 4. After the dumbbell plate support rod 2 is installed in place, the positioning column 5 will extend outward and embed into the annular groove outside the cylindrical groove in the handle 1, thereby limiting the dumbbell plate support rod 2 from sliding left and right inside the handle 1, and after the dumbbell plate 4 is added, the positioning column 5 can also fit into the annular groove.

[0035] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, the outer side of the positioning column 5 and the outer side of the piston plate at one end thereof are wrapped with a layer of rubber, and the outer side of the piston 9 is also wrapped with a layer of rubber. Therefore, there will be no air leakage between the contact surface between the positioning column 5 and the circular hole on the outer wall of the dumbbell support rod 2. The rubber on the outer side of the piston plate at one end of the positioning column 5 and the rubber on the outer side of the piston 9 can ensure the sealing of the cavity connected to the two, and ensure that the positioning column 5 can be driven to slide up and down by air pressure.

[0036] The working principle of this embodiment is that when exercising with dumbbells, the dumbbells can be picked up by holding the handle 1, and when the dumbbells need to be placed on the ground, the bottom plane of the lower support plate 3 can be in contact with the ground, thereby preventing the dumbbells from rolling around on the ground.

[0037] When it is necessary to disassemble and assemble the dumbbell plate 4 to adjust the weight of the dumbbell, first press the adjusting rod 6 toward the inside of the dumbbell plate support rod 2. At this time, the piston 9 will slide toward the position of the positioning column 5. During this process, the air in the cylindrical cavity where the piston 9 is located will enter the cylindrical cavity where the piston plate at one end of the positioning column 5 is located, thereby pushing the positioning column 5 to slide toward the inside of the dumbbell plate support rod 2. At this time, the positioning column 5 will be completely hidden in the dumbbell plate support rod 2, and then the dumbbell plate support rod 2 can be pulled out, and the adjusting rod 6 can be continued to be pressed to install or remove the dumbbell plate 4 on the outside of the dumbbell plate support rod 2. After the dumbbell plate 4 is installed, the dumbbell plate support rod 2 can be installed. One end of the support rod 2 is reinserted into the cylindrical grooves on both sides of the handle 1. When the outer wall of the dumbbell plate 4 is in close contact with the two ends of the handle 1, the adjusting rod 6 can be loosened. Because the spring 8 on the right side of the push plate 7 will also be compressed when the adjusting rod 6 is pressed toward the inside of the dumbbell plate support rod 2, the spring 8 will push the push plate 7 and the adjusting rod 6 to slide toward the outside of the dumbbell plate support rod 2 after the adjusting rod 6 is loosened. At this time, the air pressure in the cylindrical cavity where the piston 9 is located will decrease, so the air in the cylindrical cavity where the piston plate at one end of the positioning column 5 is located will be sucked into it, which will cause the positioning column 5 to slide toward the outside and extend outward, thereby locking the position of the dumbbell plate support rod 2.
