Abstract
The utility model relates to a gas meter detachment-resistant cover which comprises a protective cover main body, a positioning boss, an inverted buckle and a flange, wherein the protective cover main body is of a semicircular-ring-shaped groove structure, the positioning boss is arranged at one end, in the radial direction, of the protective cover main body, the inverted buckle which is in an inverted triangular shape is perpendicularly arranged on the positioning boss, the flange is arranged at the other end, in the radial direction, of the protective cover main body, and a hook groove is formed in the middle of the flange. The gas meter detachment-resistant cover is composed of two semicircular-ting-shaped protective covers which are buckled in an opposite mode, connection positions are completely buckled inside the detachment-resistant cover after installation is completed, a gas meter can not be detached unless the detachment-resistant cover is damaged through violence, and the gas meter detachment-resistant cover has an effect of effective monitoring, is simple in structure and convenient to install, can be used for other detachment-resistant pipelines, and is suitable for popularization.
Description
Technical field
The utility model belongs to the gas meter, flow meter field, relates to the gas meter, flow meter safety feature, especially a kind of gas meter, flow meter tamper cover.
Background technology
The security of gas meter, flow meter is very important; be directly connected to user's personal safety; the maintenance of gas pipeline and transformation all need the professional to operate; private changes gas meter, flow meter and there is great potential safety hazard in fuel gas pipeline; present fuel gas pipeline junction lacks effective protective device, has hidden danger.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of simple in structure, design science, cost gas meter, flow meter tamper cover lower, easy to use are provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of gas meter, flow meter tamper cover, it is characterized in that: comprise boot main body, positioning boss, left-hand thread and flange, boot main body is half annular groove structure, a radially end of this boot main body is shaped on positioning boss, vertically be shaped on the left-hand thread of a del on this positioning boss, the radially other end of this boot main body is shaped on flange, and the flange middle part is shaped on one and colludes groove.
And described boot main body, positioning boss, left-hand thread and the injection moulding of flange one are made.
And equal correspondence is shaped on the location lockhole of symmetry on described positioning boss and the flange.
Advantage of the present utility model and good effect are:
The utility model is made of the semi-circular guard shield of two relative snappings, after finishing installation the junction is buckled in the tamper cover fully, unless violence damage tamper cover, otherwise can't demolition diaphragm gas meter, play the effect of effective supervision, and simple in structure, easy for installation, also can be used for other tamper pipelines, be suitable for promoting.
