Abstract
The utility model provides a labyrinth seal structure for an intelligent gas meter controller box, which relates to the technical field of parts of a gas meter. The labyrinth seal structure comprises an upper controller cover, and a lower controller cover connected with the upper controller cover, wherein the lower controller cover is provided with an inner wall, an inner groove is formed at the upper end of the inner wall of the lower cover, and the outer side of the inner wall of the lower cover is connected with an outer wall of the lower cover; the upper controller cover is provided with an inner wall, and the outer side of the inner wall of the upper cover is provided with an outer wall of the upper cover; the inner wall of the upper cover is inserted into the inner groove; and the inner side surface of the outer wall of the upper cover is contacted with the outer side surface of the outer wall of the lower cover. The labyrinth seal structure solves the technical problem that the seal performance is influenced by the unreasonable seal structure of a gas meter controller shell in the prior art. The labyrinth seal structure has the beneficial effects that the sealing protection of a controller shell with the labyrinth seal structure for the gas meter is reliable, the structure is simple and reasonable, and the controller shell can be assembled and disassembled conveniently.
Description
Technical field
The utility model relates to a kind of technical field of gas meter, flow meter parts, especially relates to a kind of hermetically-sealed construction of gas meter, flow meter controller housing.
Background technology
The Along with people's growth in the living standard, it is that fuel is popularized that China city dweller uses pipe gas, has come into huge numbers of families as the measuring instrument intelligent gas meter of trade settlement.The sealing structure sexual intercourse of intelligent gas meter controller housing is to housing IP degree of protection, if the intelligent gas meter controller housing can not reach the IP65 degree of protection, the electronic control part in the housing will be impaired, directly has influence on the accuracy of metering.Chinese patent Granted publication CN201697671U, on January 5 2011 Granted publication date, name is called the utility model patent of " combined type controller box gas meter ", discloses a kind of combined type controller box of intelligent gas instrument.It is made up of combustion gas base table, controller base, counter lid, battery case etc.The controller base adopts hook and buckle mode to be connected with the counter lid, and controller base and counter lid junction are the step staggered floor, and seam crossing is provided with the rubber seal groove.This combined type controller box is designed to the individual member by the function division with base, counter, battery case, spread footing etc.; Can on the basis of base main body external member, the different functions member be installed according to the different functions demand; Through different organic assembling; Form the combined type controller box of difformity, function, thereby form the intelligent gas instrument of different function requirements, can form the intelligent gas instrument of seriation quickly and easily.But the controller base adopts hook and buckle mode to be connected with the counter lid, complex structure, and manufacturing cost is high.Controller base and counter lid junction are the step staggered floor, and seam crossing user rubber seal is inconvenient to assemble and keep in repair.Along with the gas meter, flow meter growth of service time, ageing of rubber can have influence on sealing.
Summary of the invention
In order to solve the unreasonable technical matters that influences sealing property of gas meter, flow meter controller housing hermetically-sealed construction in the prior art, the utility model provides a kind of labyrinth seal structure that seals the convenient and reliable installation and removal.
The technical scheme of the utility model is: the labyrinth seal structure of intelligent gas meter controller box, and it comprises controller loam cake and the controller lower cover that is connected with the controller loam cake, is covered with the lower cover inwall under the controller; The upper end of lower cover inwall is provided with inner groovy; The outside of lower cover inwall is connected with down cover outer wall, is covered with the loam cake inwall on the controller, and the outside of loam cake inwall is provided with cover outer wall; The loam cake inwall inserts in the inner groovy, and the medial surface of last cover outer wall contacts with the lateral surface of following cover outer wall.Airborne moisture and dust are blocked in outside the controller housing by last cover outer wall and following cover outer wall; A small amount of moisture of going up cover outer wall and following cover outer wall that gets into need pass through groove with dust and could get into controller inside, has inserted the loam cake inwall in the groove and has stopped moisture and dust entering controller inside.The controller housing sealing is reliable; Simple and reasonable, installation and removal are convenient.
As preferably, the section that following cover outer wall is connected with the lower cover inwall is ㄐ shape, between lower cover inwall and the following cover outer wall outer groove is set; Not only favourable lower cover outer wall contacts closely but also can store moisture and the dust that is stopped by loam cake inwall and lower cover inwall with last cover outer wall.
As preferably, the controller loam cake is provided with positioning boss, and last positioning boss is provided with through hole, and the controller lower cover is provided with down positioning boss, and following positioning boss is provided with screw, and last positioning boss is corresponding with the position of following positioning boss.Guaranteed that controller loam cake and controller lower cover are connected firmly.
Compared with prior art, the beneficial effect of the utility model is: the controller housing sealing protection of gas meter, flow meter labyrinth seal structure is reliable; Simple and reasonable, the controller housing installation and removal are convenient.
