Description

Novel three-phase asynchronous motor Technical Field The utility model belongs to the technical field of motors, relates to a three-phase asynchronous motor, and in particular relates to a novel three-phase asynchronous motor. Background Three-phase asynchronous motor has set up the control box on its casing generally, but this control box's seal structure is unstable, and dustproof waterproof effect is not good, leads to inside components and parts impaired, influences the use. Disclosure of Invention The utility model aims to solve the problems in the prior art and provides a novel three-phase asynchronous motor with a high-sealing control box structure. The novel three-phase asynchronous motor comprises a motor control box, wherein the motor control box comprises a shell and a cover body, screw hole connecting seats corresponding to each other are arranged on the shell and the cover body, the corresponding screw hole connecting seats are connected through screws, the novel three-phase asynchronous motor is characterized in that an outer retaining shoulder and an inner retaining shoulder are sequentially protruded from outside to inside at the top of the shell, the inner retaining shoulder is higher than the outer retaining shoulder, a sealing structure is arranged between the outer retaining shoulder and the inner retaining shoulder, the sealing structure comprises a layer of sealing part, a two-layer sealing part and a three-layer sealing part, the sealing part of the first layer sealing part is in sealing contact with the top wall of the outer retaining shoulder, the sealing part of the second layer sealing part is in sealing contact with the top wall of the shell between the outer retaining shoulder and the inner retaining shoulder, and the sealing part of the three-layer sealing part is in sealing contact with the end wall of the inner retaining shoulder, and the sealing arrangement part is downwards extended. In the novel three-phase asynchronous motor, the bottom of the shell is provided with a convex cover protruding downwards along the periphery of the shell, and the outer end of the sealing part of one layer is abutted against the inner wall of the convex cover. In the novel three-phase asynchronous motor, the shell is provided with the sealing groove for the sealing arrangement part to be connected in. Compared with the prior art, the three-phase asynchronous motor has the advantages of good sealing effect and prolonged overall service life. Drawings Fig. 1 is an overall structure diagram of the novel three-phase asynchronous motor. Fig. 2 is a sectional view of the motor control box. Fig. 3 is an enlarged view at a of fig. 2. In the figure, 1, a shell, 2, a cover body, 3, a screw hole connecting seat, 4, an outer retaining shoulder, 5, an inner retaining shoulder, 6, a layer of sealing part, 7, a layer of sealing part, 8, a layer of sealing part, 9, a sealing installation part and 10, a convex cover. Detailed Description The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
