However, the joint of the coupler and the shaft is easily contaminated by dust, and the dust enters from a gap between the coupler and the shaft to influence the sealing performance of the coupler; in addition, the existing coupler is generally fixedly connected by bolts, and the assembly efficiency is low.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention provides a dust-proof device for a coupling, which includes a first flange, a second flange and a connecting member;
a step part is arranged at one end of the first flange, a first sealing groove is arranged on the inner wall of the first flange, and a first sealing ring is arranged in the first sealing groove;
a flange matched with the step part is arranged at one end of the second flange, a second sealing groove is formed in the inner wall of the second flange, and a second sealing ring is arranged in the second sealing groove;
the connecting piece passes through connecting holes on the first flange and the second flange to fixedly connect the first flange and the second flange.
Further, the connecting piece includes connecting rod, spacing ring and locking handle, the spacing ring cover is established on the connecting rod, locking handle is eccentric and rotate and set up in connecting rod one end, the other end of connecting rod is equipped with the stopper.
Furthermore, a buffer pad is arranged on one side of the limiting ring adjacent to the locking handle.
Furthermore, a channel for the limiting block to pass through is arranged in the connecting hole of the first flange and the second flange, a limiting groove is arranged at the tail end of the connecting hole, and the limiting groove and the channel are not in the same straight line.
Compared with the prior art, the dustproof device for the coupler has the advantages that: the step part on the first flange is matched with the flange on the second flange, so that a joint between the two flanges is eliminated, the first sealing ring and the second sealing ring are used for sealing the shaft coupler and the shaft, and the sealing performance of the shaft coupler is improved; and the quick assembly and disassembly between the two flanges are realized through the connecting piece, and the assembly efficiency is greatly improved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the present invention provides a dust-proof device for a shaft coupling, which includes a first flange 1, a second flange 2 and a connecting member 3; one end of the first flange 1 is provided with a step part 11, the inner wall of the first flange 1 is provided with a first sealing groove, and a first sealing ring 12 is arranged in the first sealing groove; one end of the second flange 2 is provided with a flange 21 matched with the step part 11, the inner wall of the second flange 2 is provided with a second sealing groove, and a second sealing ring 22 is arranged in the second sealing groove; the connecting piece 3 passes through the connecting holes on the first flange 1 and the second flange 2 to fixedly connect the first flange 1 and the second flange 2.
As shown in fig. 2, the connecting member 3 includes a connecting rod 31, a stopper ring 32, and a locking handle 33; the limiting ring 32 is sleeved on the connecting rod 31, the locking handle 33 is eccentrically and rotatably arranged at one end of the connecting rod 31, the other end of the connecting rod 31 is provided with a limiting block 34, and the limiting block 34 protrudes out of the outer wall of the connecting rod 31; a buffer 35 is arranged on one side of the limiting ring 32 adjacent to the locking handle 33.
As shown in fig. 3-4, a channel 4 for the limiting block 34 to pass through is arranged in the connecting hole of the first flange 1 and the second flange 2, a limiting groove 5 is arranged at the end of the connecting hole, and the limiting groove 5 and the channel 4 are not in the same straight line.
When the coupling is assembled, the first flange 1 and the second flange 2 are respectively connected with a shaft to be connected through keys, and then the connecting piece 3 penetrates through the connecting hole; in the process that the connecting piece 3 penetrates through the connecting hole, the limiting block 34 firstly slides in along the channel 4, and when the limiting block 34 slides to the tail end of the connecting hole, the connecting piece 3 is rotated for a certain angle, so that the limiting block 34 is clamped in the limiting groove 5. The limiting ring 32 is clamped on the outer wall of the first flange 1, and the connecting piece 3 is locked with the first flange 1 and the second flange 2 by rotating the locking handle 33.
According to the utility model, the step part 11 on the first flange 1 and the flange 21 on the second flange 2 are matched with each other, so that a joint between the two flanges is eliminated, the sealing between the shaft coupling and the shaft is realized through the first sealing ring 12 and the second sealing ring 22, and the sealing performance of the shaft coupling is improved; and the connecting piece 3 realizes the quick assembly and disassembly between the two flanges, and the assembly efficiency is greatly improved.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
