In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0019] Reference Figures 1 to 4 In an embodiment of the utility model, a durable coupling comprises: an upper coupling 1, a rubber ring 2 and a lower coupling 3, characterized in that a connecting block 4 is fixedly connected to one end of the rubber ring 2, a rubber block 5 is fixedly connected to one side of the connecting block 4, and the connecting blocks 4 and the rubber blocks 5 are arranged in multiple groups, which are opened around the side of the rubber ring 2. The multiple groups of the rubber ring 2, the connecting blocks 4 and the rubber blocks 5 enable the coupling to maintain a stable working state when subjected to large torque or vibration, thereby improving the reliability and service life of the entire transmission system.

[0020] Reference Figure 1 to Figure 2 An upper mounting block 6 is fixedly connected to the upper part of the upper coupling 1, and an upper mounting opening 7 is opened above the upper mounting block 6. An upper clamping plate 8 is fixedly connected to the lower part of the upper coupling 1. There are four groups of upper clamping plates 8, which are symmetrically opened around the lower part of the upper coupling 1. During the assembly process of the coupling, the upper mounting block 6 and the upper mounting opening 7 fixed above the upper coupling 1 are used to locate and fix the position of the upper coupling 1. At the same time, the four groups of upper clamping plates 8 fixed below the upper coupling 1 can effectively prevent the axial and radial movement of the upper coupling 1, thereby improving its stability.

[0021] Reference Figure 1 to Figure 2A lower mounting block 9 is fixedly connected to the lower coupling 3, a lower mounting opening 10 is opened below the lower mounting block 9, a lower clamping plate 11 is fixedly connected to the upper part of the lower coupling 3, four groups of lower clamping plates 11 are arranged, and they are opened symmetrically around the upper part of the lower coupling 3. The lower mounting block 9 and the lower mounting opening 10 fixedly connected to the lower coupling 3 are used to locate and fix the position of the lower coupling 3, and the four groups of lower clamping plates 11 fixedly connected to the upper part of the lower coupling 3 can effectively prevent the axial and radial movement of the lower coupling 3, thereby further enhancing the stability of the entire coupling.

[0022] The working principle of the utility model is as follows: its main feature lies in the design of the rubber ring 2, one end of which is fixedly connected to a connecting block 4, and one side of the connecting block 4 is fixedly connected to a rubber block 5. This design enables the rubber ring 2 to more stably connect the upper coupling and the lower coupling and enhance the durability of the coupling. During the assembly process of the coupling, the upper mounting block 6 and the upper mounting port 7 fixedly connected to the upper coupling 1 are used to locate and fix the position of the upper coupling 1. At the same time, the four groups of upper clamping plates 8 fixedly connected to the lower side of the upper coupling 1 can effectively prevent the axial and radial movement of the upper coupling 1, thereby improving its stability. The design of the lower coupling 3 also adopts a similar principle. The lower mounting block 9 and the lower mounting port 10 fixed below the lower coupling 3 are used to locate and fix the position of the lower coupling 3, and the four groups of lower clamping plates 11 fixed above the lower coupling 3 can effectively prevent the axial and radial movement of the lower coupling 3, further enhancing the stability of the entire coupling. The multiple groups of designs of the rubber ring 2, the connecting block 4 and the rubber block 5 enable the coupling to maintain a stable working state when subjected to large torque or vibration, thereby improving the reliability and service life of the entire transmission system.

[0023] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
