Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
As shown in fig. 1 to 3, a coupling includes:
the main connecting body 1 comprises a central body 11 and a plurality of lugs 12 distributed around the central body 11, wherein a first through hole 111 is formed in the central body 11, and a fixing screw hole with the length direction along the radial direction of the first through hole 111 is formed in each lug 12;
the auxiliary connecting body 2 is provided with a containing cavity 21, the side part of the auxiliary connecting body 2 is provided with a second through hole 22, the main connecting body 1 is inserted into the containing cavity 21, the distance between the side wall of the main connecting body 1 and the side wall of the auxiliary connecting body 2 is constant, namely the containing cavity 21 is formed by amplifying the main connecting body 1 in equal proportion, and the first through hole 111 is communicated with the second through hole 22;
the elastic part 3 is filled in a gap between the main connecting body 1 and the auxiliary connecting body 2, namely, between the cavity wall of the containing cavity 21 and the main connecting body 1, and is used for providing elastic buffering for the main connecting piece and the auxiliary connecting body 2;
and each lug 12 of the fixing bolt 4 is correspondingly provided with one fixing bolt 4, and the fixing bolt 4 sequentially penetrates through the auxiliary connecting body 2 and the elastic piece 3 and then is inserted into the fixing screw hole.
The advantage that above-mentioned structure set up lies in: compared with the mode that the plum blossom elastic block is adopted to provide the buffering effect in the prior art, the elastic piece 3 is used for filling the gap between the main connecting body 1 and the auxiliary connecting body 2, so that the material consumption is less, the cost is lower, and the structure is simpler; the radial direction of the first through hole 111 is the radial direction of the connecting shaft, and the length direction of the fixing screw hole is consistent with the radial direction of the first through hole 111, so that the length direction of the fixing screw hole is consistent with the radial direction of the connecting shaft and is vertical to the axial direction of the connecting shaft.
Further, the volume of the protrusion 12 increases gradually in a direction away from the central body 11, and in this embodiment, the shape of the protrusion 12 is preferably trapezoidal. The advantages of such an arrangement are: the projection 12 and the cavity 21 can be matched stably, and transverse relative displacement is difficult to generate.
Further, the number of the projections 12 is preferably set to 3.
Further, be equipped with the extension limit 13 that extends to around on the edge of main connection body 1, extension limit 13 covers elastic component 3 avoids elastic component 3 to leak outward, influences its life.
Further, the head of the fixing bolt 4 is sunk into the auxiliary connecting body 2, so that the fixing bolt 4 is well protected.
