Description

Technical Field

[0001] This application relates to the technical field of fitness equipment, and specifically relates to an oval counterweight block. Background Art

[0002] A gym refers to a place where people can exercise. Generally, there are complete equipment and facilities in the gym, and there are relatively comprehensive fitness and entertainment projects. Gym equipment can be roughly divided into full-body fitness equipment, local fitness equipment, and small fitness equipment. When using some of these equipment, in order to cooperate with the use of personnel, counterweight blocks are added to achieve a better exercise effect. Different people use different weights and numbers of counterweight blocks according to their own situations, and use the weights generated by these counterweight blocks for exercise.

[0003] The connecting rings in the counterweight block installation holes are often made of plastic. After long-term use, the connecting rings are prone to wear or damage, resulting in poor limiting effect of the connecting rings on the counterweight block during use. Moreover, the connecting rings are fixedly installed in the counterweight block, making it difficult to replace the connecting rings after wear or damage, which will affect the user experience during exercise. Therefore, this application proposes an oval counterweight block to solve the above technical problems. Utility Model Content

[0004] In view of the deficiencies of the prior art, this application provides an oval counterweight block, which has the advantages of being convenient for replacing the connecting ring, etc., and solves the problem that the connecting ring is fixedly installed in the counterweight block, making it difficult to replace the connecting ring after wear or damage.

[0005] To achieve the above object, this application provides the following technical solution: An oval counterweight block, including a counterweight block body, a connecting ring, and a limiting block. A fixing hole is opened at the top of the counterweight block body. There are two installation holes opened at the top of the counterweight block body. The connecting ring is movably installed on the inner side wall of the installation hole. A sliding groove is opened on the inner side wall of the installation hole. The limiting block is fixedly installed on the outer side of the connecting ring. There are two moving mechanisms arranged on the counterweight block body. A clamping mechanism is arranged on the moving mechanism. There are four noise reduction mechanisms arranged on the counterweight block body;

[0006] The two moving mechanisms include a lead screw, a rotating block, and a limiting plate. An installation groove is opened inside the counterweight block body. A placement groove is opened on the outer side of the counterweight block body. The lead screw is rotatably connected inside the counterweight block body and the lead screw is located inside the installation groove. The rotating block is fixedly installed on the side of the lead screw away from the fixing hole. The limiting plate is fixedly installed on the side of the lead screw close to the fixing hole.

[0007] By adopting the above technical solution, by rotating the rotating block, the rotating block will drive the lead screw to rotate. The rotating lead screw will drive the moving plate connected by external threads to move. At the same time, the moving plate is slidably connected to the outside of the guide rod, so that the moving plate will not rotate with the lead screw. The moving plate will drive the mounting plate to move away from the fixed hole through the connecting rod. The mounting plate will drive the limiting rod to move. After pulling the limiting rod out of the limiting groove, the connecting ring can be taken out of the mounting hole. After putting a new connecting ring into the mounting hole, the above operations are reversed to limit the connecting ring. This makes it more convenient to replace the connecting ring, thus ensuring the experience of personnel when using the counterweight for exercise.

[0008] Further, the limiting block is slidably connected in the sliding groove, and the outer side of the limiting block is closely attached to the inner side wall of the sliding groove.

[0009] By adopting the above technical solution, this makes it more convenient to replace the connecting ring and makes the connecting ring more stable during use.

[0010] Further, the two moving mechanisms are symmetrically arranged on the counterweight body along the fixed hole.

[0011] By adopting the above technical solution, this makes the effect of the moving mechanism driving the clamping mechanism to limit the connecting ring in the fixed hole better.

[0012] Further, the rotating block is located inside the placement groove, and a number of rubber strips are fixedly installed on the outer side of the rotating block.

[0013] By adopting the above technical solution, this makes the rotating block not interfere with the normal use of the counterweight and makes it more convenient to rotate the rotating block.

[0014] Further, the clamping mechanism includes a moving plate, two connecting rods, a mounting plate, two guide rods and a limiting rod. The moving plate is threadedly connected to the outside of the lead screw. The two connecting rods are fixedly installed on the side of the moving plate close to the fixed hole. The mounting plate is fixedly installed between the ends of the two connecting rods close to the fixed hole. The two guide rods are fixedly installed on the inner side wall of the mounting groove. A limiting groove is opened on the outer side of the connecting ring. The limiting rod is fixedly installed on the side of the mounting plate close to the fixed hole.

[0015] By adopting the above technical solution, the connecting ring in the fixed hole can be limited by the clamping mechanism.

[0016] Further, the mounting plate is slidably connected between the outer sides of the two guide rods.

[0017] By adopting the above technical solution, this makes the mounting plate not rotate with the lead screw.

[0018] Further, the limiting rod penetrates through the counterweight body, and the limiting rod is located in the limiting groove.

[0019] By adopting the above technical solution, the connecting ring can be limited by the limiting rod in this way.

[0020] Further, the noise reduction mechanism includes a connecting block and a rubber column. A fixing groove is formed at the top of the counterweight body. The connecting block is fixedly installed on the inner side wall of the fixing groove. The rubber column is fixedly installed on the top of the connecting block. A connecting groove is formed at the bottom of the counterweight body.

[0021] By adopting the above technical solution, in this way, when the plurality of counterweights move up and down reciprocally and when the counterweights are lowered, the lack of fixation between adjacent counterweights can be avoided, and the adjacent counterweights will knock against each other, reducing the noise generated by such knocking.

[0022] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0023] For this oval counterweight, by rotating the rotating block, the rotating block will drive the lead screw to rotate. The rotating lead screw will drive the moving plate threadedly connected to the outside to move. At the same time, the moving plate is slidably connected to the outside of the guiding rod, so that the moving plate will not rotate together with the lead screw. The moving plate will drive the mounting plate to move away from the fixing hole through the connecting rod. The mounting plate will drive the limiting rod to move. After the limiting rod is pulled out of the limiting groove, the connecting ring can be taken out of the mounting hole. After a new connecting ring is placed into the mounting hole, the above operations are reversed, and the connecting ring can be limited. In this way, when replacing the connecting ring, it is more convenient, thus ensuring the experience of personnel when using the counterweight for exercise. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting ring 4 is movably installed on the inner side wall of the mounting hole 3. A sliding groove 5 is opened on the inner side wall of the mounting hole 3. The limiting block 6 is fixedly installed on the outer side of the connecting ring 4. The limiting block 6 is slidably connected in the sliding groove 5. The outer side of the limiting block 6 is in close fit with the inner side wall of the sliding groove 5. Two moving mechanisms are arranged on the counterweight body 1. The two moving mechanisms are symmetrically arranged on the counterweight body 1 along the fixed hole 2. A clamping mechanism is arranged on the moving mechanism.

[0031] The two moving mechanisms include a lead screw 73, a rotating block 74 and a limiting plate 75. A mounting groove 71 is opened inside the counterweight body 1. A placing groove 72 is opened on the outer side of the counterweight body 1. The lead screw 73 is rotatably connected inside the counterweight body 1 and the lead screw 73 is located inside the mounting groove 71. The rotating block 74 is fixedly installed on the side of the lead screw 73 away from the fixed hole 2. The rotating block 74 is located inside the placing groove 72. A number of rubber strips are fixedly installed on the outer side of the rotating block 74. The limiting plate 75 is fixedly installed on the side of the lead screw 73 close to the fixed hole 2.

[0032] The clamping mechanism includes a moving plate 81, two connecting rods 82, a mounting plate 83, two guide rods 84 and a limiting rod 86. The moving plate 81 is threadedly connected to the outside of the lead screw 73. The two connecting rods 82 are fixedly installed on one side of the moving plate 81 close to the fixing hole 2. The mounting plate 83 is fixedly installed between the ends of the two connecting rods 82 close to the fixing hole 2. The mounting plate 83 is slidably connected between the outside of the two guide rods 84. The two guide rods 84 are fixedly installed on the inner side wall of the mounting groove 71. A limiting groove 85 is formed on the outside of the connecting ring 4. The limiting rod 86 is fixedly installed on one side of the mounting plate 83 close to the fixing hole 2. The limiting rod 86 penetrates through the counterweight body 1, and the limiting rod 86 is located in the limiting groove 85.

[0033] In this embodiment, through the cooperation between the moving mechanism and the clamping mechanism, the connecting ring 4 in the fixing hole 2 can be quickly disassembled and replaced, so as to ensure the experience of personnel when using the counterweight body 1 for exercise.

[0034] Please refer to Figure 1 Fig. 2 or Fig. 3. In this embodiment, there are four noise reduction mechanisms provided on the counterweight body 1.
