[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. They rotate together during the transmission of motion and power and do not disengage under normal circumstances. It is sometimes also used as a safety device to prevent the connected parts from being subjected to excessive loads, thus playing the role of overload protection.

[0003] The existing plum blossom coupling is composed of two mounting plates and an elastic member therebetween. If the tooth block on the mounting plate is damaged or the elastic member is deformed, the entire mounting plate or the elastic member must be replaced, which increases unnecessary waste. Therefore, a coupling is proposed, in which the first mounting plate and the second mounting plate are connected together by multiple connecting columns and elastic sleeves. If a single connecting column and the elastic sleeve are damaged, they can be disassembled and replaced. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a coupling, which connects a first mounting plate and a second mounting plate together through a plurality of connecting columns and elastic sleeves. If a single connecting column and elastic sleeve are damaged, they can be disassembled and replaced.

[0006] A connecting assembly is equidistantly arranged between the first mounting plate and the second mounting plate outside the elastic block. The connecting assembly includes connecting columns equidistantly arranged between the first mounting plate and the second mounting plate, and an elastic sleeve is sleeved on the outer side of the connecting column.

[0007] By adopting the above technical solution, the first mounting plate rotates to drive the second mounting plate to rotate through the connecting column, the elastic sleeve and the elastic block, and the connecting column and the elastic sleeve can be disassembled and replaced separately.

[0008] Specifically, a first sleeve is disposed on a side of the first mounting plate away from the second mounting plate, and a first slot is formed on a side of the first mounting plate away from the first sleeve.

[0011] Specifically, a thread groove is provided inside the connecting column, and self-locking screws corresponding to the second slot are equidistantly arranged on one side of the second mounting plate.

[0012] Specifically, arc-shaped blocks are welded on the top end and the bottom end of the connecting column.

[0013] Beneficial effects of the utility model:

[0014] (1) The coupling described in the utility model is that after the first mounting plate and the second mounting plate are installed, one end of the connecting column is inserted into the reserved groove and fixed with a bolt self-locking screw, and then the elastic block is sleeved on the outer side of the spacing shaft, the first mounting plate and the second mounting plate are moved toward each other, the elastic block is clamped in the first clamping groove and the second clamping groove, and the connecting column and the elastic sleeve on the outer side are inserted into the receiving groove.
