Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1: a sealing washer structure for motor stator linkage unit, including injection molding 1 and the cover establish the sealing washer 2 in injection molding 1 periphery. As shown in fig. 3 and 4: the inner wall of the sealing ring 2 is provided with two rings of raised sealing rings 3 at intervals along the circumferential direction, the sealing rings 3 act on the outer circumferential surface of the injection molding part 1, and the bottom surface of the sealing ring 2 is provided with a convex ring 4. The convex ring 4 is positioned in the middle of the bottom surface of the sealing ring 2.
The sealing ring 2 comprises a framework 5 and a rubber piece 6, wherein the framework is of an annular structure, the inner wall surface of the rubber piece 6 extends outwards to form a sealing ring 3, and the bottom surface of the rubber piece 6 extends outwards to form a convex ring 4.
The 5 structures of skeleton are used for supporting the utility model discloses a structure can satisfy the leakproofness requirement, can satisfy the shaping shape requirement of structure again. The cross section of the framework 5 is of an inverted L-shaped structure, the framework 5 comprises an annular piece 5a and a flanging 5b, the annular piece 5a is embedded in the rubber piece 6, and the flanging 5b extends out of the rubber piece 6 from the top of the outer wall of the rubber piece 6.
