[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1: As Figure 1-3As shown, a concealed gas valve includes a housing 100, a top cover 200 mounted on the housing 100, and a mounting mechanism disposed on the outside of the housing 100 for installing the concealed gas valve. It also includes a transmission mechanism disposed on one side of the mounting mechanism for driving the mounting mechanism to perform automatic installation. The mounting mechanism includes a frame 101, which is bolted to the outside of the housing 100. A lead screw 102 is rotatably connected to the middle of the frame 101. A top rod 103 is drively connected to the outside of the lead screw 102. Rotation of the lead screw 102 drives the top rod 103 to move. A pressing plate 104 is rotatably connected to one end of the top rod 103. The pressing plate 104 can rotate along one end of the top rod 103. Multiple protrusions 105 are uniformly welded to the outer wall of the pressing plate 104, increasing the friction of the pressing plate 104. One end of the lead screw 102 is bolted to... The bevel gear A106, the inner wall of the top cover 200 is cut with a groove 310, and a sealing ring 320 is attached to the inner wall of the groove 310. The sealing ring 320 improves the sealing performance between the housing 100 and the top cover 200. The transmission mechanism includes a fixed frame 201, which is fixed to the inner wall of the housing 100 by bolts. A rotating shaft 202 is rotatably connected to the middle position of the fixed frame 201. A bevel gear B203 is fixed to one end of the rotating shaft 202 by bolts. The bevel gear A106 meshes with the bevel gear B203. An internal hexagonal nut 204 is welded to the top of the rotating shaft 202. The internal hexagonal nut 204 drives the rotating shaft 202 to rotate. A vent hole is cut at the bottom of the housing 100. A track 110 is fixed to the bottom of the housing 100 by bolts. A drying box 120 is slidably connected to the inner wall of the track 110. The drying box 120 dries the space inside the buried gas valve.

[0033] In this embodiment, a pistol drill drives the internal hexagonal nut 204 to rotate, which in turn drives the rotating shaft 202 to rotate. Under the meshing transmission of bevel gear A106 and bevel gear B203, the lead screw 102 rotates. The rotation of the lead screw 102 drives the push rod 103 to move, pressing the extrusion plate 104 into the mounting groove. At the same time, the extrusion plate 104 can rotate according to the inner wall of the mounting groove. Multiple push rods 103 cooperate with each other, making it difficult for the buried gas valve to meet the installation of grooves of various sizes, thus improving the applicability of the buried gas valve.

A screw 304 is threaded to the inner wall of the threaded groove 303. The screw 304 connects the side plate 301 and the fixing block 302 under the action of the threaded groove 303. A gas leak sensor 300 is fixed to the middle position of the top cover 200 by bolts. The gas leak sensor 300 detects the gas content inside the concealed gas valve to prevent leakage. A gas valve mechanism is located in the middle position of the housing 100. The gas valve mechanism is used to conduct or block gas flow. It includes a base 401, which is bolted to the middle of the housing 100. A bracket 402 is bolted to the top of the base 401, and a gas pipe 403 is bolted to the top of the bracket 402. A valve 404 is installed on one side of the gas pipe 403, and a turntable 405 is bolted to one end of the valve 404. The turntable 405 drives the valve 404 to rotate, thus opening or closing the valve. Connectors 406 are bolted to both ends of the gas pipe 403. A groove 410 is cut in the middle of the top cover 200, and a baffle 420 is slidably connected to the inner wall of the groove 410. The baffle 420 can slide along the groove 410 to open or close the top of the concealed gas valve. A handle 430 is bolted to the top of the baffle 420.

[0035] In this embodiment, the side plate 301 is connected to the fixing block 302 by the screw 304 under the action of the threaded groove 303.
