Description

Technical Field

[0001] The utility model relates to a concealed box, in particular to a concealed box for a gas self-closing valve, and belongs to the technical field of gas self-closing valve installation. Background Art

[0002] Gas self-closing valves are usually installed on low-pressure gas system pipelines. When the gas supply pressure in the pipeline is under-pressure or over-pressure, the device can automatically close without electricity or other external power. When the gas self-closing valve is installed in the wall together with the gas pipe, the gas self-closing valve is generally placed in a valve box and then buried in the wall. The gas self-closing valve is protected by the valve box.

[0003] A gas valve box disclosed in the Chinese patent application disclosure specification CN219588255U can be used without installing supporting parts when decorating a house to avoid scratching or damaging the panel during decoration. At the same time, the protective cover can protect the valve to prevent damage to the valve during decoration. The protective cover can be directly used to fix the pressure pipe sleeve without providing a locking structure between the pressure pipe sleeve and the box body, making the installation of the pressure pipe sleeve easier. At the same time, when disassembling and assembling the valve, the pressure pipe sleeve provides a retreat space for the gas pipe.

[0004] In the above patent solution, the hole position for installing the valve is fixed, and the installation dimensions of valves of different brands vary greatly. This means that in the actual installation process, valves of different brands need to be additionally processed and adjusted to ensure that they fit perfectly with the box. This additional processing step not only increases the complexity and time cost of the installation, but may also cause some installation errors and problems. In addition, the protective cover is installed on the box by bolts. When there is a problem with the valve and it needs to be checked, the staff needs to spend more time and energy to remove and reinstall the protective cover, thereby extending the duration of the entire maintenance process.

[0009] Furthermore, a slide groove is provided on one side of the fixed frame, a moving block is fixed on the side of the slider close to the slide groove, and the outer surface of the moving block is slidably connected to the inner wall of the slide groove, which can guide and limit the movement of the slider.

[0010] Furthermore, a sliding rod is fixed to the side of the slider away from the threaded rod, and the end of the sliding rod away from the slider passes through the fixed frame. A limiting block is fixed to the end of the sliding rod passing through the fixed frame, which can further guide and support the movement of the slider.

[0011] Furthermore, a turning handle is fixed to one end of the threaded rod located outside the fixed frame, and a pulling handle is fixed to one end of the insertion rod located outside the U-shaped plate.

[0012] Furthermore, a cover is fixed to the upper surface of the protective shell, and the bottom surface of the cover is in contact with the upper surface of the box body, and openings are provided on both the protective shell and the cover.

[0013] Furthermore, a bolt hole is provided on the bottom surface of the box body, and the self-closing valve body can be fixed by bolts.

[0014] Furthermore, a mounting bracket is plugged into the opening of the box body, a support plate is fixed to the side of the mounting bracket close to the bolt hole, a pipe pressing sleeve is fixed to the side of the mounting bracket away from the support plate, a pressure plate is fixed to the side of the protective shell close to the mounting bracket, and the pressure plate is located above the support plate and in contact with the support plate, so that the pipe pressing sleeve can be plugged into the box body for easy replacement, and the protective shell can limit the mounting bracket to prevent shaking.
