Description

Technical Field

[0001] This utility model relates to the field of coupling technology, specifically a modular coupling that can be quickly assembled and disassembled. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during the transmission of motion and power, and to remain connected under normal conditions. It is used to absorb vibration and compensate for radial and angular misalignments.

[0003] However, during long-term use, the internal elastic element of the existing coupling will be subjected to prolonged compression, which can easily lead to excessive deformation and cracks in the elastic element.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN213393211U discloses a combined coupling, comprising a left coupling body, a right coupling body, and a plum blossom elastic element. Multiple protruding teeth matching the plum blossom elastic element are fixedly connected to the two adjacent end faces of both the left and right coupling bodies. The plum blossom elastic element is positioned between the left and right coupling bodies. A U-shaped elastic skeleton within the cavity of the plum blossom elastic element enhances its rigidity, preventing excessive deformation and cracking during use, thus extending the coupling's service life. Furthermore, the spring enhances the elasticity of the U-shaped elastic skeleton, making it easier for it to return to its original shape after deformation, further extending its service life and thus improving the overall service life of the coupling.

[0005] The above-mentioned device increases the rigidity of the plum blossom elastic element by using the set elastic skeleton during use, thereby preventing the plum blossom elastic element from cracking. However, in the above-mentioned device, the elastic skeleton only increases the rigidity of the plum blossom elastic element, and the tightness of the coupling is poor, which makes the coupling easy to fall off during operation. Therefore, in actual use, the coupling may fall off easily during operation. Utility Model Content

[0006] The purpose of this invention is to provide a modular coupling that can be quickly assembled and disassembled, in order to solve the problem mentioned in the background art that couplings are prone to falling off during operation.

[0008] A connecting column is fixedly installed on the outer surface of the left coupling body, and the outer surface of the connecting sleeve movably abuts against the right coupling body, and a sealing mechanism is provided between the right coupling body and the connecting column;

[0009] A limiting block is fixedly installed on the outer surface of the left coupling body, a positioning screw is threaded on the inner side of the connecting sleeve, and a disassembly and assembly mechanism is provided between the positioning screw and the limiting block.

[0010] Furthermore, a protective shell is movably mounted on the outer surface of the limiting block, the disassembly and assembly mechanism includes the protective shell, a limiting groove is formed on the inner side of the protective shell, and the protective shell and the limiting block form a self-locking structure.

[0011] Furthermore, a fixing rod is fixedly installed on the outer surface of the left coupling body, a support plate is fixedly installed at the top of the fixing rod, and a connecting piece is fixedly installed at the top of the support plate, and the support plate and the connecting piece form an integral structure.

[0013] Furthermore, a base is fixedly installed on the outer surface of the positioning column, a support plate is fixedly installed on the bottom surface of the base, and a plum blossom elastic element is movably installed on the top of the support plate.

[0014] Furthermore, a protective shell is movably mounted on the outer surface of the right coupling body, a positioning screw is threadedly mounted on the inner side of the right coupling body, and a support plate is movably abutted against the inner side of the protective shell.

[0015] Furthermore, a limiting link is fixedly installed on the outer surface of the right coupling body, and a positioning plate is fixedly installed on the outer surface of the limiting link, and the positioning plate and the limiting link form an integral structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
