DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 6 , in the embodiment of the present utility model, a weighing weight convenient for assembly includes a weight body 1. A convex cap 2 is integrally formed in the middle of the top end of the weight body 1. The convex cap 2 has a T-shaped cylindrical structure. First magnets 3 are embedded on both symmetric side walls in the middle of the convex cap 2. A groove 4 for accommodating the convex cap 2 is provided in the middle of the bottom end of the weight body 1. First through holes 5 are provided at both ends of the inner wall of the groove 4. Second through holes 6 communicating with the first through holes 5 are provided at both ends of the outer wall of the weight body 1. A clamping mechanism 7 is installed between the second through holes 6 and the groove 4;

[0023] Among them, the clamping mechanism 7 includes a guide rod 701. The guide rod 701 is located in the second through hole 6, and one end of the clamping mechanism 7 extends into the groove 4. A fixing ring 702 is integrally formed in the middle of the guide rod 701. The fixing ring 702 is located in the second through hole 6. A connecting member 703 is connected to the outer side end of the second through hole 6. A spring 704 is sleeved on the outer wall of the guide rod 701. The spring 704 is located between the fixing ring 702 and the connecting member 703. One end of the guide rod 701 extending into the groove 4 is fixedly connected with a fixing block 705. A second magnet 706 is embedded on the end face of the fixing block 705 away from the first through hole 5;

[0024] When the first magnet 3 and the second magnet 706 have opposite magnetic poles and are close to each other, the repulsive force between the first magnet 3 and the second magnet 706 completely compresses the broken spring 704.

[0025] In this embodiment: Most of the existing assembled weights fix two independent weights into one by means of threaded connection. Although the threaded connection structure is relatively simple, it may be more troublesome to disassemble. After a period of use or improper operation during the installation process and other factors, the threads may be worn or stuck, thereby increasing the disassembly difficulty. Therefore, in this solution, a clamping mechanism 7 is provided between the upper and lower ends of the weight. The clamping mechanism 7 can be used to quickly assemble and fix two weights. In addition, the opposite magnetic poles of the first magnet 3 and the second magnet 706 are used to force the clamping mechanism 7 to release the assembly and fixation between the two weights. The operation is indirect and the assembly is firm, greatly improving the disassembly and assembly efficiency between the weights.

[0026] Please pay special attention to Figures 1 to 6, a through hole for one end of the guide rod 701 to penetrate and move is provided in the middle of the connecting piece 703, and the connecting piece 703 is fixedly connected to the second through hole 6 by threads.

[0027] In this embodiment: The connecting piece 703 is of an annular structure. The through hole in the middle allows the guide rod 701 to penetrate and move. External threads are provided on the outer wall of the connecting piece 703, and mating internal threads are also provided at the position of the second through hole 6 corresponding to the connecting piece 703, thus facilitating the fixed installation and disassembly of the connecting piece 703 and providing convenience for replacing the spring 704 later.

[0028] Please refer specifically to Figures 1 to 6 , when the convex cap 2 is completely inserted into the groove 4 on another weight body 1, the first magnet 3 and the second magnet 706 are on the same horizontal line; the fixed block 705, the second magnet 706 and the first magnet 3 are all of arc-shaped structures, and the inner arc of the second magnet 706 is matched with the outer arc of the first magnet 3.

[0029] In this embodiment: Both the second magnet 706 and the first magnet 3 are in two groups. When the second magnet 706 and the first magnet 3 are close to each other and have opposite magnetic poles, the second magnet 706 and the first magnet 3 attract each other magnetically, thereby improving the connection strength between the two weights. When the second magnet 706 and the first magnet 3 are close to each other and have the same magnetic poles, the second magnet 706 and the first magnet 3 repel each other magnetically, forcing the guide rod 701 to move outward and compress the spring 704 until the fixed block 705 releases the limit on the convex cap 2, and then the two connected weights can be quickly separated.

[0030] Please refer specifically to Figures 1 to 6 , marks 8 are engraved on both outer side walls of the weight body 1, and the two marks 8 are respectively located on one side of the two engaging mechanisms 7; the two marks 8 are respectively the magnetic pole marks of the "S" pole and the "N" pole.

[0031] In this embodiment: The two marks 8 can facilitate the staff to observe, indicating the approximate positions of the engaging mechanisms 7 with the two marks 8, and at the same time can also show whether the second magnet 706 and the first magnet 3 are close to each other and the magnetic directions of the two groups of magnetic poles, thus facilitating the accurate judgment of the connection state between the two weights.

[0032] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
