In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

a booster pump box cover comprises a plurality of bosses arranged on a sealing surface and a sealing gasket arranged on the sealing surface, wherein the sealing gasket is abutted and positioned with the plurality of bosses simultaneously; the heights of the bosses are equal, and the thickness of the sealing gasket is larger than the height of the bosses, so that the compression amount of the sealing gasket is equal to the difference between the thickness and the height.

Optionally, the upper surfaces of a plurality of said bosses are parallel to said sealing face.

Optionally, the outer diameter of at least one of said bosses is different from the outer diameter of the remaining bosses.

Optionally, the outer diameter of the plurality of bosses gradually increases or decreases in a clockwise direction.

Optionally, a plurality of oblique angles are arranged on the bosses, slopes are arranged on the sealing gaskets, and the slopes are matched with the oblique angles in shape.

Optionally, an extension portion is further disposed on the sealing gasket, the extension portion covers the upper surface of the boss, and the extension portion exposes at least an inner hole of the boss after the booster pump box cover is mounted on the booster pump.

The utility model has the advantages that: the utility model provides a booster pump box cover, which comprises a plurality of bosses arranged on a sealing surface and a sealing gasket arranged on the sealing surface, wherein the sealing gasket and the plurality of bosses are simultaneously abutted and positioned; the heights of the bosses are equal, and the thickness of the sealing gasket is larger than the height of the bosses, so that the compression amount of the sealing gasket is equal to the difference between the thickness and the height. The utility model provides a pair of booster pump case lid, seal structure on it, compact structure, it is convenient to assemble, and the leakproofness is good.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

In the description of the present application, it is to be understood that the terms "upper surface", "outside", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.

Referring to fig. 1-4, the present invention provides a cover of a booster pump, which includes a plurality of bosses 2 disposed on a sealing surface 1, and a gasket 3 mounted on the sealing surface 1, wherein the gasket 3 and the plurality of bosses 2 are abutted and positioned at the same time; the heights of the bosses 2 are all equal, and the thickness of the sealing gasket 3 is larger than the height of the bosses 2, so that the compression amount of the sealing gasket 3 is equal to the difference between the thickness and the height.

As a further improvement to the above, the upper surfaces of the plurality of bosses 2 are parallel to the sealing surface 1 to ensure consistent gasket compression.

As a further improvement to the above scheme, the outer diameter of at least one boss 2 is different from the outer diameters of the rest bosses 2, and the matching size of the abutting positions of the sealing gasket 3 and the boss 2 is correspondingly modified, so that the pressure of each abutting position and the pressure of the outer side wall of the boss 2 are kept consistent, and the design also effectively prevents the sealing gasket from being installed wrongly. In an embodiment, the outer diameters of the plurality of bosses 2 gradually increase or decrease in a clockwise direction, and specifically, referring to fig. 2, the boss 2 includes a first boss 21, a second boss 22, a third boss 23, and a fourth boss 24, and the outer diameter of the first boss 21 < the outer diameter of the second boss 22 < the outer diameter of the third boss 23 < the outer diameter of the fourth boss 24.
