Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of power transmission line dust plug for electromechanical equipment.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of power transmission line dust plug for electromechanical equipment, comprise catch and stick harness, described stick harness is cylinder cylinder, described catch is annular catch, and one end of described stick harness is fixedly connected with described catch, in described stick harness, be provided with annular brace sheet, described stick harness arranged outside has outside back-up ring, and described stick harness inner side is provided with inner side back-up ring.
Particularly, the internal diameter of described stick harness equals the internal diameter of described catch.
Particularly, be provided with the through hole coordinating with described stick harness on the shell of described electromechanical equipment, the diameter of described through hole is less than the diameter of described stick harness, and the external diameter of described power transmission line is greater than the internal diameter of described stick harness and described catch.
By power transmission line through the through hole in stick harness simultaneously by stick harness plug to the through hole of electromechanical equipment, avoid dust to enter by the gap between power transmission line and electromechanical equipment, through hole and the power transmission line of dust plug and electromechanical equipment all adopt interference fit simultaneously, reduce the possibility that dust enters.
Preferably, described outside back-up ring and described inner side back-up ring are multiple, and are evenly distributed on outside and the inner side of described stick harness.
Multiple back-up rings are all set inside and outside stick harness, further strengthen the dust tightness of dust plug.
Particularly, the internal diameter of described outside back-up ring equates with the external diameter of described stick harness, and the external diameter of described inner side back-up ring equates with the internal diameter of described stick harness.
Particularly, described annular brace sheet is high-strength alloy steel support chip, and the axle center of described annular brace sheet and the axle center of described stick harness be positioned at same position, and the length of described annular brace sheet is less than the length of described stick harness.
In stick harness inside, metallic support sheet is set, makes dust plug not yielding, increase its useful life.
Preferably, described stick harness, described outside back-up ring, described inner side back-up ring and described catch are high resiliency flexible rubber body.
The beneficial effects of the utility model are: the utility model is arranged between power transmission line and electromechanical equipment for the power transmission line dust plug of electromechanical equipment, and make stick harness and electromechanical equipment and power transmission line all adopt interference fit, make not exist between power transmission line and electromechanical equipment gap, avoid dust to enter electromechanical equipment inside by the gap between power transmission line and electromechanical equipment, improved the dust-proof effect of electromechanical equipment.
