Description

Door leaf switch gas tightness detects frock

Technical Field

The utility model relates to an air tightness detects technical field, specifically is a door leaf switch air tightness detects frock.

Background

In recent years, rail trains develop rapidly in China, high-speed rail traveling has become the choice of most people, and related manufacturing industries also develop rapidly. The high-speed rail has a complex structure, a plurality of parts on the vehicle are arranged, and the manufacture and the detection of each part must be strictly treated.

The BP switch is an important switch on a train, and the normal operation of equipment can be guaranteed only by ensuring certain tightness of the BP switch, so that a device is required to perform local tightness detection on the BP switch. And certain portability is required because of the small quantity.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a door leaf switch gas tightness detects frock to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a door leaf switch gas tightness detects frock, includes the cavity, the cavity is cylindrical structure, the bottom fixedly connected with sealing rubber circle of cavity, the top suction nozzle of cavity, the through-hole is seted up to the lateral wall of suction nozzle, set up the barometer in the through-hole.

Preferably, the inner diameter of the air suction nozzle is 20mm, and the depth of the air suction nozzle is 20 mm.

Preferably, the inner diameter of the through hole is 14 mm.

Compared with the prior art, the beneficial effects of the utility model are that: simple structure, facilitate the use, regard as air extraction equipment with the dust catcher, can satisfy the functional requirement and have the portability again, carry out the gas tightness with this device and detect can effectively raise the efficiency to the BP switch.
