Problems solved by technology
It can be seen that although the above-mentioned patents can solve the problems of high energy consumption, high pollution, low efficiency, and high cost, they are of no help to solve the technical problems of the present invention. The hard shell will not only damage the ground, but most importantly cannot Solve the connection strength between the barbell plate and the barbell bar, that is to say, the huge impact force on the connection between the barbell plate and the barbell bar will cause the sleeve (4) to break away from the barbell plate, resulting in damage to the barbell plate

Embodiment Construction
[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail;
[0020] Such as figure 1 , 2 , 3, 4, and 5, a high-strength barbell plate includes a barbell plate body 1 of a disc structure, and the barbell plate body 1 includes a filling rubber layer 2, and an outer rubber layer 3 is wrapped outside the filling rubber layer 2 , the center of the barbell body 1 is provided with a mounting hole 4 for assembling with the barbell bar through the filling rubber layer 2 and the outer rubber layer 3, and the inner wall surface of the mounting hole 4 is also wrapped with the outer rubber layer 3, This structure can completely wrap the rubber-filled layer, which improves the overall strength of the rubber-filled layer 2. A shaft sleeve 5 combined with the outer rubber-covered layer 3 for assembly and connection with the barbell bar is provided in the mounting hole 4. A fixing part for strengthening the connection s...

The invention discloses a high-strength barbell plate, which comprises a barbell plate body with a disc structure. The barbell plate body includes a filling rubber layer, and an outer rubber layer is wrapped outside the filling rubber layer. The rod is assembled through the mounting hole of the filling rubber layer and the outer covering rubber layer. A shaft sleeve combined with the outer covering rubber layer is provided in the mounting hole for assembling and connecting with the barbell bar, and the shaft sleeve is provided with a shaft for reinforcing A fixed component that connects the cover with the outer rubber layer. Through experiments, the full film produced by this patented technology has increased the drop resistance to 20,000 times, and the bonding strength between the metal mandrel and rubber has increased from 1,000 kg to 4,000 kg. The structure is reasonable, strong, durable, and the shock absorption effect is very outstanding; there is no strong collision impact between metal parts, no excessive noise, the landing shock absorption effect is superior, and the ground damage will not be caused. The application prospect is very broad.
Description
technical field [0001] The invention relates to a sports equipment, in particular to a high-strength barbell plate. Background technique [0002] Barbell is the most commonly used sports equipment for strength training and weightlifting. Because the barbell is heavy, when it is performing barbell training or weightlifting competition, the sound of falling down is very loud, causing a great impact and causing large ground damage. , Due to its heavy weight, it is inevitable that the metal parts inside the barbell will collide with each other, resulting in deformation and damage. Therefore how to improve the connection strength between the barbell plate and the barbell bar and effectively protect the ground from damage is a problem to be solved urgently by those skilled in the art. Barbells are equipment used for weightlifting. They are divided into barbell bars and barbell plates. Barbell plates were originally made of stone and metal with a large specific gravity. With the r...
