Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

It should be noted that, in the description of the technical solutions of the present invention, some directional words, such as "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", etc., used for clearly describing the technical features of the present invention are all in terms of the orientation of the drawings of the present invention.

Examples

As shown in fig. 1 and 2, the leakage-proof power-assisted oil cup of the embodiment comprises an oil cup cover 1 and a cup body 2, wherein a threaded portion 21 is arranged at the top of the cup body 2, and the cup body 2 is in threaded connection with an internal thread on the oil cup cover 1 through an external thread of the threaded portion 21. The oil cup cover 1 comprises a cover body and a U-shaped connecting piece with a downward opening, the U-shaped connecting piece comprises a second connecting ring 5, a third connecting ring 6 and a fourth connecting ring 7 which are sequentially connected, the second connecting ring 5 and the fourth connecting ring 7 are arranged in parallel, the third connecting ring 6 is vertically connected between the top ends of the second connecting ring 5 and the fourth connecting ring 7, the cover body is connected with the second connecting ring 5 of the U-shaped connecting piece through a first connecting ring 4, and the inner side wall of the cover body, the first connecting ring 4 and the second connecting ring 5 are combined to form an annular oil storage cavity 3. One side of the second connecting ring 5 close to the fourth connecting ring 7 is provided with an internal thread matched with the external thread of the thread part 21. The distance between the second connection ring 5 and the fourth connection ring 7 is greater than the wall thickness of the threaded portion 21 so as to accommodate the threaded portion 21 entering between the second connection ring 5 and the fourth connection ring 7 to be in threaded connection with the second connection ring 5. The lower side wall of the third connecting ring 6 of the embodiment is provided with a gasket 9 for sealing, and the gasket 9 is a rubber gasket or a silicone gasket, so that when the threaded part 21 of the cup body 2 is screwed to the top of the U-shaped connecting piece, the top of the threaded part 21 abuts against the gasket 9, and sealing can be better realized. In addition, in order to strengthen the overall strength of the structure, improve the practicability and prolong the service life, a plurality of reinforcing ribs 10 are circumferentially arranged between the second connecting ring 5 and the inner side wall of the oil cup cover 1.

As shown in fig. 3, an annular seal ring 8 is fixedly connected to the bottom of the fourth connection ring 7 on the side close to the second connection ring 5 in this embodiment, the seal ring 8 is a rubber seal ring, the rubber seal ring and the fourth connection ring 7 are clamped and fixed by matching a clamping groove, an annular protrusion 211 is correspondingly fixedly connected to the inner side wall of the threaded portion 21, the cross-sectional structure of the annular protrusion 211 in this embodiment is a semi-arc structure, and the distance between the annular protrusion 211 and the seal ring 8 in the horizontal direction is smaller than or equal to 0, so that when the threaded portion 21 is screwed to the top of the U-shaped connection member, the seal ring 8 is abutted to the annular protrusion 211 and forms an over-clearance fit, so as to achieve a.

Adopt above-mentioned structural design, when oil cup lid 1 and 2 threaded connection of cup are together, even the car takes place to jolt at the in-process of traveling, lead to fluid to rock and go upward even the screw thread appears becoming flexible, nevertheless because adopted U type connecting piece in the oil cup lid 1, fourth go-between 7 be located screw thread portion 21 inside and with screw thread portion 21 inside wall between sealed the setting, so fluid can not get into threaded connection department and leak out even, but can enter into oil storage chamber 3 along fourth go-between 7, third go-between 6.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
