[0002] In order to make the interior more beautiful, some users will install the gas pipes and gas valves in the wall in a concealed manner. In order to protect the concealed gas valves, a protective box is generally installed to protect the gas valves.

[0003] When carrying out traditional concealed gas pipeline construction, there are generally the following disadvantages: 1. When users carry out concealed construction of gas pipes in non-finely decorated houses, gas construction personnel generally need to visit the site more than twice to complete the concealed work. The first visit is for survey and design, the second is for concealed gas pipeline construction in rough houses, and the third is to install panels and knobs for users. The need for multiple visits increases labor costs; 2. When grooving the shear wall, when the groove depth reaches a certain depth, it will encounter steel bars in the wall, making construction difficult; 3. In the process of going from rough walls to finely decorated walls, plastering and tiling are required, which makes the groove depth uncontrollable, and then the workers' construction depth varies. Traditional concealed valve protection boxes are difficult to apply to concealed grooves of different depths.

[0035] Embodiment 1:

[0036] like Figures 1 to 6 A concealed protection box for a gas valve shown in the figure comprises a box body 1 which is open at the top and at least one side, a first connecting structure for connecting the gas valve is provided at the bottom of the inner cavity of the box body 1, a support cover 3 for covering the open top of the box body 1 is slidably connected to the box body 1, sliding plates 36 which can slide along the inner side wall of the box body 1 are provided on both sides of the support cover 3, an insertion port 31 for allowing a hand to insert into the inner cavity of the box body 1 is also provided on the upper part of the support cover 3, and a flip cover 6 for covering the insertion port 31 is also provided on the support cover 3.

[0037] When gas construction workers install the concealed protection box of the gas valve into the concealed groove of the wall, they can first deliver the support cover 3 to the owner, and then insert it into the insertion gap 4 by themselves after the wall surface is finished, thereby reducing the labor expenditure of one visit and reducing costs. When buckling the support cover 3, the owner can control the insertion depth of the sliding plate 36 according to the groove depth, so that the concealed protection box of the gas valve can be suitable for concealed grooves with different groove depths. The support cover 3 is provided with a flap 6 for covering the extension port 31. When the gas valve needs to be adjusted, the flap 6 can be directly opened to reach into the concealed protection box of the gas valve to adjust the valve, which is very convenient and quick.

[0038] Specifically, the sliding plate 36 is integrally formed with the support cover 3 , and a protrusion 311 is provided on the outer wall of the sliding plate 36 , which can abut against the inner wall of the box body 1 to increase the friction between the two. The protrusion 311 is integrally formed with the sliding plate 36 .

[0039] One side of the flip cover 6 is rotatably connected to the support cover 3, and the other side of the flip cover 6 is provided with a locking structure capable of locking the flip cover 6 on the support cover 3. The locking structure can be a self-locking switch 33 provided on the support cover 3 and a locking block 61 provided on the flip cover 6 that can press the self-locking switch 33 to lock with the self-locking switch 33. The locking and unlocking functions can be achieved by pressing the flip cover 6, and the operation is very convenient and quick. Of course, the flip cover 6 can also be provided with a buckle to be connected to the support cover 3.

[0040] In one embodiment, a protective cover 2 for protecting the gas valve is further provided in the box body 1. A pipe insertion port 21 is provided on the protective cover 2 corresponding to the side opening of the box body 1. A first through hole 22 for extending the adjusting knob of the gas valve is provided on the upper portion of the protective cover 2. The gas valve can be protected by the protective cover 2 when the wall is plastered. After the wall is plastered, the support cover 3 can be buckled in by the householder.
