Abstract
The utility model relates to a liquid seepage prevention structure for a three-phase fast-forward asynchronous motor lead wire, which comprises a motor case and a lead wire, wherein a press plate is arranged on the outer wall of the motor case, one end of the press plate is fixedly connected with the outer wall of the motor case, the press plate is in a bent state and forms a gap with the outer wall of the motor case, and the lead wire passes through the gap formed between the press plate and the outer wall of the motor case after being bent and is fixed by the press plate. The lead wire of the motor passes through a wire outlet hole and the press plate to form an S-shaped bending part when penetrating out of the motor case. When the axial direction of a motor is in the horizontal direction, the height of at least one part of the lead wire on the horizontal plane is lower than the height of the wire outlet hole of the motor on the horizontal plane, and liquid flowing along the lead wire directly falls onto the ground at the lowest position of the lead wire without falling into the motor case. The liquid seepage prevention structure has the advantages that the structure is simple, the liquid seepage prevention structure is light, ingenious and durable, the appearance is attractive, the size is small, the noise is low, and the liquid seepage prevention structure is suitable for equipment such as small-size machine tools, textile machinery and the like.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to three-phase F.F. asynchronous motor, particularly a kind of three-phase F.F. asynchronous machine lead wire seepage-proof liquid structure.
Background technology:
Extensively adopt three-phase F.F. Asynchronous Motor Driving action component in lathe and the Weaving device.And action component often uses a large amount of cooling liquids in the course of the work.In the prior art, the wire hole of the power supply lead wire of three-phase F.F. asynchronous motor from motor case picks out casing.In the use, liquid enters motor case inside along lead wire through wire hole easily, causes electrical fault.
Summary of the invention:
The purpose of this utility model is to provide a kind of three-phase F.F. asynchronous motor lead wire seepage-proof liquid structure, and the power line that described this three-phase F.F. asynchronous motor lead wire seepage-proof liquid structure will solve three-phase F.F. asynchronous motor in the prior art draws the access node structure technical problem that liquid enters motor case inside takes place easily.
This three-phase F.F. asynchronous motor lead wire seepage-proof liquid structure of the present utility model comprises a motor case and a lead wire, be provided with a wire hole in the circle wall of described motor case, described lead wire passes described wire hole in motor case, wherein, the outer wall of described motor case is provided with a pressing plate, one end of described pressing plate is fixedlyed connected with the outer wall of motor case, pressing plate is bending and forms the gap with the outer wall of motor case, passes the gap of pressing plate and motor case outer wall after the outer lead wire bending of wire hole and is fixed by pressing plate.
Further, the lead wire bend to the distance in electric machine casing axle center greater than the lead wire of pressing plate downside distance to the electric machine casing axle center.
Further, be provided with the line protective sleeve in the wire hole, lead wire passes the described line protective sleeve of crossing.
Operation principle of the present utility model is: motor lead is when passing motor case, through wire hole and pressing plate, form the bending of S type, when the axial along continuous straight runs of motor is provided with, lead wire has at least a part to be lower than the height of motor wire hole on horizontal plane at the height on the horizontal plane, directly land in the extreme lower position of lead wire along the lead wire flowing liquid, can not enter in the motor case.
The utility model and prior art are compared, and its effect is actively with tangible.The utility model is provided with a pressing plate outside the casing of three-phase F.F. asynchronous motor, utilize the pressing plate lead wire that wire hole is outer to be fixed on the outer wall of motor case, make motor lead through wire hole and pressing plate the time, form the bending of S type, thereby lead wire has at least a part to be lower than the height of motor wire hole on horizontal plane at the height on the horizontal plane, directly land in the extreme lower position of lead wire along the lead wire flowing liquid, can not enter in the electric machine casing.The utility model is simple in structure, and lightly durable, aesthetic in appearance, volume is little, and noise is low, is fit to equipment such as junior machine, textile machine.
Description of drawings:
Fig. 1 is the structural representation of three-phase F.F. asynchronous motor lead wire seepage-proof liquid structure of the present utility model.
