Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1, a modular mask comprises a bottom case 1 and a case cover 2, wherein the bottom case 1 is covered with the case cover 2, one end of the bottom case 1 is connected with one end of the case cover 2 through a rotating shaft 101,

the middle part of the bottom box 1 is a square hollow fixing frame 102;

specifically, the gas meter is placed into the modular mask through the fixing frame 102, and the other end of the box cover 2 is uncovered, so that the box cover 2 and the bottom box 1 can be buckled or separated due to the action of the rotating shaft 101.

The side wall of one side of the bottom box 1 is provided with a first arc-shaped through hole 301 and a second arc-shaped through hole 302, and the side wall of the other side of the bottom box 1 is provided with a third arc-shaped through hole 303.

Both ends of the fixing frame 102 are provided with screw fixing holes 103.

Specifically, the screw is fixed to the wall to which the gas meter is hooked through the screw fixing hole 103, so that the modular mask is fixed to the wall.

The first arc-shaped through hole 301 and the second arc-shaped through hole 302 are arranged at intervals.

The first arc-shaped through hole 301 and the third arc-shaped through hole 303 are oppositely arranged.

Specifically, the first arc-shaped through hole 301 and the third arc-shaped through hole 303 are used for penetrating through an air inlet pipeline or an air outlet pipeline of the gas meter; the second arc-shaped through hole 302 is used as a spare through hole and can be used for penetrating other gas pipes of the gas meter.

A square empty groove is formed in the middle of the box cover 2 and is buckled with the groove cover 201; both ends of the slot cover 201 are provided with mounting holes 202.

The slot cover 201 and the box cover 2 can be fixed through the mounting holes 202 and the screws; when the gas meter needs to be checked, the screw can be detached, the groove cover 201 is separated from the box cover 2, and the gas meter can be simply overhauled through the square empty groove.

The height of the box cover 2 is gradually reduced along the direction away from the rotating shaft 101.

The height of the box cover 2 is matched with that of the gas meter, so that space is saved.

The front end height and the rear end height of the bottom box 1 are consistent, namely, the height of the bottom box 1 is consistent front and back.

The bottom box 1 and the box cover 2 are transparent.

The whole transparent material that is of this modularization face guard, the state of the gas table of being convenient for observe.

The bottom box 1 and the wall top of the rotating shaft 101 on the side away from each other are provided with inserting notches 104, and the inner walls of the inserting notches 104 are provided with rubber strips 105.

Referring to fig. 2, specifically, the end of the box cover 2 away from the rotating shaft 101 is inserted into the insertion slot 104, and the rubber strip 105 can increase the friction force between the box cover 2 and the insertion slot 104, thereby preventing the box cover 2 and the bottom box 1 from being easily separated.

Wherein the rubber strip 105 is arranged on the groove wall of the insertion groove opening 104.
