When the mounting plate 3 is installed on the mounting seat 2, the front and rear side walls of the dust cover 32 are respectively abutted and contacted with the front and rear inner walls of the corresponding reserved groove 1. At this time, the dust cover 32 cannot be removed for cleaning to prevent the dust cover 32 from being lost. The dust cover 32 can only be removed when the mounting plate 3 and the gas leak alarm 100 are moved out of the reserved groove 1.

[0019] Furthermore, as shown in the figure, the limiting mechanism described in this embodiment includes a first slide groove 40 provided on the mounting seat 2, a first rack 41 is movably installed in the first slide groove 40, the first rack 41 is movably installed in the first slide groove 40 through a second spring 44, one end of the second spring 44 is fixedly connected to the inner wall of the first slide groove 40, the other end of the second spring 44 is fixedly connected to the inner end of the first rack 41, the outer end of the first rack 41 is in contact with the side wall of the mounting plate 3, one side of the first rack 41 is meshed with a gear 42, the gear 42 is rotatably installed in the first slide groove 40, one side of the gear 42 is meshed with a second rack 43, the second rack 43 and the first rack 41 are not on the same vertical plane to avoid interference between the second rack 43 and the first rack 41 when sliding, and the first slide groove 40 A second slide groove 45 is provided on the side wall, and the second rack 43 is slidably installed in the second slide groove 45. A third slide groove 46 is provided at one end of the second rack 43. A wedge-shaped slider 48 is elastically installed in the third slide groove 46 through a third spring 47. One end of the third spring 47 is fixedly connected to the inner wall of the third slide groove 46, and the other end of the third spring 47 is fixedly connected to the outer wall of the wedge-shaped slider 48. A slot 49 corresponding to the wedge-shaped slider 48 is provided on the side wall of the gas leak alarm 100. When the wedge-shaped slider 48 is inserted into the corresponding slot 49, the gas leak alarm 100 is only allowed to move from right to left. A guiding inclined surface inclined toward the outside of the wedge-shaped slider 48 is provided on the right side wall of the wedge-shaped slider 48. A telescopic rod 50 is fixedly installed on the mounting plate 3, and the movable end of the telescopic rod 50 is in contact with the side wall corresponding to the wedge-shaped slider 48. Align the mounting plate 3 and the gas leak alarm 100 with the mounting seat 2 and install them from right to left. In this process, the movable end of the telescopic rod 50 first abuts against the right side wall of the wedge-shaped slider 48, and then the mounting plate 3 and the gas leak alarm 100 continue to be moved to the left to compress the telescopic rod 50 until the wedge-shaped slider 48 is inserted into the corresponding slot 49. At this time, the left wall of the mounting plate 3 abuts against the outer end of the first rack 41 to cooperate, thereby limiting the mounting plate 3 and the gas leak alarm 100. When disassembly is required, only the mounting plate 3 and the gas leak alarm 100 need to be pressed. The device 100 causes it to continue to move to the left, and the mounting plate 3 drives the first rack 41 to slide to the left in the first slide groove 40, driving the gear 42 meshing with it to rotate, and then drives the second rack 43 meshing with the gear 42 to move toward the inside of the second slide groove 45, until the wedge-shaped slider 48 no longer abuts against and contacts the movable end of the telescopic rod 50, and the movable end of the telescopic rod 50 is not blocked by the wedge-shaped slider 48 and then extends, blocking the slot 49, so that the wedge-shaped slider 48 cannot be inserted into the slot 49, thereby releasing the limit on the mounting plate 3 and the gas leak alarm 100.

[0020] Furthermore, as shown in the figure, the limiting mechanisms described in this embodiment are symmetrically distributed on the upper and lower sides of the mounting base 2. The symmetrically distributed limiting mechanisms can make the gas leak alarm and the mounting plate 3 more stable during the installation process.

[0021] Furthermore, as shown in the figure, the mounting plate 3 of the present embodiment is provided with a second countersunk hole 60, and a hexagon socket countersunk bolt is installed in the second countersunk hole 60, and the inner end of the hexagon socket countersunk bolt can abut against and contact with the side wall of the mounting seat 2. By using a hexagon socket wrench to tighten the hexagon socket countersunk bolt located in the second countersunk hole 60, when the inner end of the hexagon socket countersunk bolt abuts against and contacts with the side wall of the mounting seat 2, the mounting plate 3 cannot continue to move toward the inside of the mounting seat 2, thereby preventing the mounting plate 3 from being pressed and accidentally falling off.
