In use, two plate bodies 1 are engaged with each other by the engaging assembly 3, and the two plate bodies 1 are difficult to rotate relative to each other by means of the limiting assembly 2, thereby the two weight plates are easy to assemble and disassemble.

[0051] Referring to FIGS. 1 and 2, the plate body 1 is in a rectangular plate shape, a circular central hole 11 is provided at the center of the plate body 1, and the central hole 11 extends through the thickness of the plate body 1. The engaging assembly 3 includes an engaging head 31 and a fixture block 32. The engaging head 31 is in a cylindrical shape, one end of the engaging head 31 in an axial direction is arranged in the central hole 11, and the engaging head 31 is fixedly connected to the plate body 1. A stiffener 312 in a cross shape is fixedly arranged on the inner wall of the engaging head 31, and the engaging head 31 inserts into central holes 11 of adjacent weight plates.

[0052] Referring to FIGS. 1 and 2, a plurality of engaging blocks 311 are circumferentially fixed on an outer side wall of one end, outside the central hole 11, of the engaging head 31. One end, away from the engaging head 31, of the engaging block 311 fits with the inner wall of the central hole 11. A plurality of fixture blocks 32 are circumferentially arranged on an inner wall of one end, away from the engaging head 31, of the central hole 11. The fixture blocks 32 are integrally connected or detachably fixed with the plate body 1. The fixture blocks 32 are in one-to-one correspondence with the engaging blocks 311. One end of a fixture block 32 away from the inner wall of the central hole 11 fits with the outer side wall of the engaging head 31.

[0053] Referring to FIGS. 1 and 2, a gap is reserved between two adjacent fixture blocks 32, and the engaging block 311 can extend through a gap between two adjacent fixture blocks 32. When the engaging head 31 rotates in a central hole 11 of an adjacent weight plate, the engaging head 31 abuts on a side of the fixture block 32, facing the interior of the central hole 11, by means of the engaging block 311.

[0054] In use, an engaging block 311 of one plate body 1 is staggered with a fixture block 32 of another plate body 1, and then the engaging block 311 passes through a gap between adjacent fixture blocks 32; after the engaging block 311 completely extends through the fixture block 32, the engaging head 31 is rotated until the engaging block 311 is aligned directly with the fixture block 32, thereby the engaging head 31 is inserted into the central hole 11. In this way, the engaging block 311 and the fixture block 32 are in an engaging state, thereby an engaging connection of two plate bodies 1 can be realized by means of the engaging assembly 3.

[0055] Referring to FIGS. 1 and 3, a limit groove 13 is formed on one side of the plate body 1 close to the engaging head 31, the limit groove 13 extends through one side of the plate body 1 in a thickness direction, and the limit groove 13 is rectangular. A limit cover 24 is inserted into the limit groove 13. The limit cover 24 is fixedly connected to the plate body 1. The limit cover 24 is rectangular columnar and hollow inside. A length direction of the limit cover 24 is the same as that of the limit groove 13. One side, close to the bottom of the limit groove 13 in a length direction, of the limit cover 24 is open, and one end, close to the center of the plate body 1 in a length direction, of the limit cover 24 is open.

The elastic part 23 further includes a second spring 232, which is fixedly arranged between the button 21 and the plate body 1, and the second spring 232 is arranged along the sliding direction of the button 21.

[0061] Referring to FIG. 5, the button 21 extends toward the sliding block 22 to form two push blocks 212. The two push blocks 212 are symmetrically arranged on both sides of the button 21 in the sliding direction. The two push blocks 212 are arranged on a side of the button 21 close to the limiting block 221, and one end of the push block 212 close to the sliding block 22 is inclined towards a side close to the limiting block 221 in a direction close to the sliding block 22, one end of the sliding block 22 close to the push block 212 is inclined towards a side away from the limiting block 221 along a direction close to the push block 212, and the sliding block 22 abuts against and fits with the inclined end close to the push block 212.

[0062] In use, after two plate bodies 1 engage with each other by means of the engaging assembly 3, the limiting block 221 of one plate body 1 remains in the engaging state with the engaging groove 12 of another plate body 1 under the action of the first spring 231; the protrusions 211of the button 21 keeps in an abutting state with the stop block 242 of the limit cover 24 under the action of the second spring 232; by pressing the button 21 and compressing the second spring 232 at the same time, the button 21 slides in a direction close to the sliding block 22; at the same time, the sliding block 22 is pushed to slide by means of the inclined plane abutted between the push block 212 and the sliding block 22; at the same time, the first spring 231 is compressed such that the limiting block 221 disengages with the engaging groove 12; the sliding block 22 is pushed by the button 21, thereby the process of the sliding block 22 driving the limiting block 221 disengaging the engaging groove 12 is more conveniently and quickly. After releasing the button 21, the button 21 can automatically return to its original position under the elastic force of the second spring 232, and the sliding block 22 can automatically return to its original position under the elastic force of the first spring 231, thereby the button 21 can automatically reset after pushing the sliding block 22, making the process of pushing the sliding block 22 by the button 21 more conveniently and quickly.

[0063] The implementation principle of Embodiment 1 is as follows: in use, pressing the button 21 of one plate body 1 to slide the limiting block 221 into the limit cover 24, compressing the first spring 231 and the second spring 232, the engaging block 311 of one plate body 1 is staggered from the fixture block 32 of another plate body 1, thereby the engaging head 31 of one plate body 1 can be inserted into the central hole 11 of another plate body 1; rotating one plate body 1 until the engaging block 311 of one plate body 1 faces the fixture block 32 of the other plate body 1, and then releasing the button 21 of one plate body 1; the button 21 is reset under the action of the second spring 232, while the sliding block 22 is reset under the action of the first spring 231, and the sliding block 22 drives the limiting block 221 to slide out of the limit cover 24, the limiting block 221 of one plate body 1 engages in the engaging groove 12 of the other plate body 1, and then a plurality of weight plates are assembled in the same way. When removing the plate body 1, by pressing the button 21 of the plate body 1 to be taken, the limiting block 221 of the plate body 1 to be taken slides into the limit cover 24; and then by rotating the plate body 1 to be taken, when the engaging block 311 of the plate body 1 to be taken staggers with a fixture block 32 with which the engaging block 311 of the plate body lengages, the plate body 1 to be taken can be removed, thereby realizing the convenient assembly and disassembly of two adjacent plate bodies 1.
