Description

External gas meter box

Technical Field

The utility model belongs to the technical field of gas table case device, concretely relates to external gas table case.

Background

Present gas meter case, the volume is the important a lot relatively with the table, it is very inconvenient during the installation, present gas table when the installation, always need two people to cooperate and install, especially when installing on the resident outer wall, one person with the hand fixed ammeter, another person drills and adorns the screw with the electric drill, just can accomplish the installation work of gas table, meet this kind of two people cross work, there is installation safety risk, it develops work to be difficult to more when reforming transform or installing in some places that the space is narrow such as old district, and the supervise personnel can't carry out safety supervision moreover.

In addition, most of gas meter boxes are complex in structure, high in design and development cost and difficult to save energy and protect environment due to waste of materials, for example, CN2009101167311 split combined gas meter box is analyzed structurally, the gas meter box cannot be used singly, at least two gas meter boxes can be combined, otherwise, when the gas meter box is used singly, dust and rainwater can corrode the gas meter box from one side, and the using effect of the gas meter is affected.

For example, CN207456548U is a header fixedly connected SMC combined gas meter box, which is very simple in structure, but during installation, it is encountered that the gas pipeline cannot extend into the meter box, and a worker needs to open a hole temporarily.

Although the structure of the novel gas meter box of CN107655535A is simple, the novel gas meter box also has a gas pipeline installation hole, when the novel gas meter box is to be installed on a passageway or a wall, the novel gas meter box cannot root and be fixed, and even if the novel gas meter box needs to be installed, the novel gas meter box can only be installed by workers considering to be drilled, which is particularly troublesome and affects the working efficiency.

Like CN 206362405U's a gas table case and gas management system, the second through-hole at this kind of table case top leads to it to leak easily to lead to the case intake corrosion, shorten its life.

In order to overcome the technical problems, the applicant researches an external gas meter box to meet social requirements.
