Description

A protective box for a gas meter

technical field

The utility model relates to a protective box for a gas meter.

Background technique

At present, the known gas meter protective box is generally installed at the same time as the gas meter. During installation, the protective box is first fixed, and then the gas meter is installed in the protective box. Sufficient operating space is reserved in the protective box, resulting in an excessively large size of the protective box. In addition, for some gas meters without protective boxes, if a protective box needs to be installed later, since the gas meter has been fixedly connected to the gas inlet and outlet pipes, the gas meter must be removed first to install the protective box. The quantity is relatively large, and disassembling and assembling the gas meter may cause damage to the gasket, which will cause leakage hazards if the seal is not tight.

The authorized announcement number is CN204165605U, and the Chinese utility model patent whose authorized announcement date is 2015.02.18 discloses a gas meter oil pollution protection cover, which includes a transparent cover that matches the shape of the gas meter. The matching nozzle (that is, the relief slot used to get out of the way of the gas pipeline), and the cover is provided with a step block for easy installation and removal. The cover is a glass cover, and it can be seen from the drawings in the published specification that there is no fixed structure connected to the gas meter or the wall on the cover. In addition, according to the context of the specification, such a The purpose of the glass cover is to prevent dust and oil pollution from contaminating the gas meter, and the cover needs to be easily disassembled for cleaning. From this we can see that the glass cover should be directly buckled on the gas meter through the nozzle.

Although the use of this cover can prevent pollution and is easy to disassemble and clean, but because there is no fixed structure on the cover, the cover is easy to fall off in windy weather or in a vibrating workplace, and the glass cover is fragile. and the equipment below cause a great potential safety hazard. In addition, for home users, the gas meter needs to be recharged and swiped frequently. Since the cover is completely buckled on the gas meter, when swiping the card, the cover needs to be removed first, and then buckled after swiping, which is very inconvenient to operate. .

Utility model content

The purpose of the utility model is to provide a gas meter protection box which is convenient to be directly fixed on the outside of the gas meter connected to the gas pipeline, and the fixing is relatively firm so that the safety hazard is low, and at the same time, it is convenient for the user to swipe the card.

In order to achieve the above object, the utility model adopts the following technical solutions:

A protective box for a gas meter, comprising a box body with a front panel and an opening on the rear side, and a relief groove for letting the gas pipeline out of the way is provided on the side of the box body so that the box body can be directly covered on the outside of the gas meter. The side is also provided with a fixing structure for fixing the gas meter protection box on the wall, and the front panel of the box body is provided with a bayonet slot.

The box body includes a top plate, a left side plate and a right side plate, the lower part of the box body is also an open structure, and the relief groove is arranged on the top plate.

The fixing structure is a fixed lug plate respectively fixed on the left side plate and the right side plate, and the fixed lug plate is provided with a fixing hole.

The front panel is provided with a transparent observation window above the card slot.

The front panel is hinged on the upper part of the box body, and the hinge axis between the front panel and the box body extends along the left-right direction.

The box body also includes a door frame connected to the left side panel, the right side panel and the top panel, the front panel is hinged on the door frame, and the hinge axis between the front panel and the door frame is located at the top of the front panel and extends along the left and right directions.

The beneficial effect of the utility model is that: the gas pipeline can be opened through the step-off groove so that the box body can be directly covered outside the gas meter without disassembling the gas meter, and the installation is convenient; The box is fixed on the wall with a fixed structure, through which the box can be firmly fixed, preventing the box from falling and hurting pedestrians or other equipment, reducing potential safety hazards; and it is precisely because the box is fixed on the wall In fact, it is impossible to remove the box every time the card is swiped, so a card slot is set on the front panel, and the card can be swiped directly through the card slot, which is very convenient to use.
