Technical Field

[0001] The utility model relates to the field of couplings, in particular to a coupling with stable connection. Background Art

[0002] A coupling, also known as a coupling, is a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms so that they rotate together and transmit motion and torque. It is sometimes used to connect the shaft with other parts. It is often composed of two halves, which are connected by keys or tight fits, fastened to the two shaft ends, and then connected in some way. It is sometimes used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection. When using a coupling, the connection is usually not stable enough, so a coupling with a stable connection is required.

[0003] The existing coupling with stable connection cannot improve the stability of the coupling connection during operation, cannot be flexibly used at different angles during operation, and cannot protect the connection position. Therefore, a coupling with stable connection is urgently needed. Utility Model Content

[0006] A connecting pipe is installed at one end of the connecting block, threaded holes are provided at the upper and lower ends of the connecting pipe, a threaded rod is installed at the upper end of the connecting block, and a sleeve is installed at one end of the connecting pipe.

[0007] A connecting head is installed at one end of the connecting pipe, a stabilizing frame is sleeved on the outer end of the connecting head, and screws are installed at the upper and lower ends of the stabilizing frame.

[0008] Preferably, the connection block is threadedly connected to the linkage body through a fixing hole, and the connection block is arranged in an open hole style.

[0009] Preferably, the connecting pipe is threadedly connected to the connecting block through a threaded rod, and the connecting pipe is symmetrically arranged with respect to the central axis of the linkage body.

[0010] Preferably, the sleeve is movably connected to the connecting pipe, and the sleeve is symmetrically arranged with respect to the central axis of the linkage body.

[0011] Preferably, the size of the inner wall of the sleeve is the same as the size of the outer wall of the connector, and the sleeve is sleeve-connected to the connector.

[0012] Preferably, the connector forms a rotating structure with the connecting pipe through a movable shaft, and the outer wall size of the connector is closely fitted with the inner wall size of the fixed frame.
