Description

Water-proof structure of water quality detector

Technical Field

The utility model belongs to the technical field of the water quality testing device technique and specifically relates to a water quality testing appearance's waterproof construction.

Background

The water quality detector plays an important role in environmental protection, water quality detection and water resource protection in order to protect water environment and monitor sewage discharge. Along with the development of industry, the types of sewage are more and more, and the requirements required by the protection grade of the corresponding water quality detector shell are higher and higher.

In the prior art, the one-level waterproofing of the commonly adopted waterproofing technology is waterproof, the structure has short service life and low waterproofing grade, and sewage easily enters the water quality detector to corrode and damage internal parts of the water quality detector.

Disclosure of Invention

The utility model aims at overcoming the not enough of existence among the prior art, provide a simple and reliable and water quality testing appearance's that protection level is high waterproof construction.

According to the technical scheme provided by the utility model, the waterproof structure of the water quality detector comprises an upper shell, a lower shell, an upper sealing ring and a lower sealing ring; the upper shell and the lower shell are fixed together through a fastener, an upper sealing ring is arranged between the lower end face of the upper shell and the upper end face of the lower shell, a lower sealing ring is arranged between the inner circle of the lower end part of the upper shell and the outer circle of the upper end part of the lower shell, and the stress direction of the upper sealing ring and the stress direction of the lower sealing ring are perpendicular.

An upper shell folded edge is integrally connected to the outer circle of the lower end part of the upper shell, and an upper sealing ring groove for placing an upper sealing ring is upwards formed in the lower end face of the upper shell along the inner circle of the upper shell folded edge.

The lower shell is arranged on the outer circle of the lower shell, the lower shell edge is arranged on the outer circle of the lower shell corresponding to the lower position of the upper end face of the lower shell, and a lower sealing ring groove used for placing a lower sealing ring is formed in the outer circle of the lower shell and along the upper end face of the lower shell edge.

The cross section of the lower sealing ring groove is in a semi-elliptical shape.

The utility model discloses a waterproof sealing structure of the perpendicular atress of second grade, the sealed effect of second grade is better, and the atress direction mutually perpendicular of two sealing washers can be to the effective protection of soaking of various directions, realized purposes such as reliable, with low costs, water-proof effects are good.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

The utility model discloses a waterproof structure of a water quality detector, which comprises an upper shell 1, a lower shell 2, an upper sealing ring 3 and a lower sealing ring 4; go up casing 1 and lower casing 2 and pass through the fastener and fix together, be equipped with upper seal circle 3 between the lower terminal surface of last casing 1 and the up end of casing 2 down, be equipped with lower seal circle 4 between the lower tip excircle of last casing 1 and the upper end excircle of casing 2 down, and the direction of stress of upper seal circle 3 is perpendicular setting with the direction of stress of lower seal circle 4.

An upper shell folded edge 11 is integrally connected to the outer circle of the lower end portion of the upper shell 1, and an upper seal ring groove 12 for placing the upper seal ring 3 is formed in the lower end face of the upper shell 1 upwards along the inner circle of the upper shell folded edge 11.

A lower casing flange 21 is integrally connected to the outer circle of the lower casing 2, the lower casing flange 21 is arranged on the outer circle of the lower casing 2 corresponding to the lower position below the upper end face of the lower casing 2, and a lower seal ring groove 22 for placing a lower seal ring 4 is arranged on the outer circle of the lower casing 2 and along the upper end face of the lower casing flange 21.

The cross-sectional shape of the lower seal ring groove 22 is a semi-ellipse.

The utility model discloses during the installation, in the last seal ring groove 12 of packing into of upper seal circle 3, the lower casing 2 embedding of casing hem 21 top is gone up in the seal ring groove 12 and is extruded upper seal circle 3 down, has realized the lower terminal surface of last casing 1 and the up end of casing 2 down between sealed, has realized the horizontal direction upper seal promptly.

The lower seal ring 4 is arranged in the lower seal ring groove 22, the inner circle of the upper shell folded edge 11 extrudes the lower seal ring 4, and the seal between the inner circle of the upper shell folded edge 11 and the outer circle of the lower shell 2 above the lower shell folded edge 21 is realized, namely the seal in the vertical direction is realized.
