[0002] A household combustible gas detector is a device used to detect the concentration of combustible gases in a home environment. When the gas concentration reaches a preset threshold, the detector will trigger an alarm to remind residents to take appropriate measures to avoid potential dangers.

[0003] Chinese patent publication number CN307264925S, publication date 20220415, discloses a household combustible gas detector, whose main body includes a detection alarm body and a connection base, wherein the detection alarm body includes a middle shell, an upper cover, a PCB board and electrical components integrated on the PCB board.

[0004] Existing quick-release alarms for household combustible gas detectors, such as the above-mentioned ones, mostly first fix the connecting base and the middle shell by fastening, and then complete the connection between the connecting base and the external support by using the mounting rod. In the specific implementation process, multiple sets of fastening rods for fixing the connecting base and the middle shell are all the rear end face of the integrated sub-mounting base, which will be inconvenient when the detection alarm body needs to be independently disassembled and assembled later. Therefore, it is urgent to propose a corresponding connecting base for combustible gas detectors to solve the above problems. Utility Model Content

The rear end face of the middle seat is fixedly connected to a side seat. The inner wall of the side seat is integrated with a socket and an elastic component for pushing the socket to extend and retract. A limiting component for limiting the socket is provided between one side of the socket and the side seat. The other side of the socket is plugged into the inner wall of the mounting base through a coupling groove.

[0008] Preferably, the alignment component includes a protrusion fixedly connected to the outer wall of the mounting base, and the outer wall of the protrusion is engaged with the inner wall of the middle seat through a slot.

[0009] Preferably, a plurality of groups of mounting plates are fixedly connected to the outer wall of the arc-shaped end of the mounting base, and the plurality of groups of mounting plates are distributed in an arc shape.

[0010] Preferably, the elastic component includes an inner plate fixedly connected to the inner surface wall of the side seat, the socket is an I-shaped structure, and a spring is fixedly connected between the inner plate and the inner surface wall of the socket.

[0024] A connecting base for a combustible gas detector includes a mounting base 1 and a middle base 2. The middle base 2 is sleeved on the front side of the mounting base 1, and an alignment component is provided between the inner surface wall of the middle base 2 and the mounting base 1. The rear end face of the middle base 2 is fixedly connected to the side base 3. The inner surface wall of the side base 3 is integrated with a socket 9 and an elastic component for pushing the socket 9 to expand and contract. A limiting component for limiting the socket 9 is provided between one side of the socket 9 and the side base 3. The other side of the socket 9 is plugged into the inner surface wall of the mounting base 1 through a coupling groove 7.

[0025] After connecting the mounting base 1 to the designated area through the cooperation of the external fixing rod and the mounting piece 4, the middle seat 2 is put on the front side of the mounting base 1, holding the pull ring 12 and driving the rotating seat 11 to rotate ninety degrees through the pull ring 12 until the rotating seat 11 is flush with the socket 9. At this time, the spring 10 pushes the socket 9 out of the side seat 3 and plugs into the inside of the coupling groove 7. The rotating seat 11 is coupled to the inside of the side seat 3 under the linkage of the socket 9, thereby realizing the fixed connection between the middle seat 2 and the mounting base 1. Subsequently, it is only necessary to drive the socket 9 to separate the coupling groove 7 through the pull ring 12 to realize the independent disassembly and assembly of the middle seat 2, thereby ensuring the stable cooperation between the mounting base 1 and the middle seat 2 while improving the convenience of independent disassembly and assembly of the middle seat 2.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the alignment component includes a protrusion 6 fixedly connected to the outer wall of the mounting base 1, and the outer wall of the protrusion 6 is engaged with the inner wall of the middle seat 2 through the card slot 5. In the process of sleeve-mounting the middle seat 2 on the front side of the mounting base 1, the axial position of the middle seat 2 is continuously switched until the card slot 5 is engaged with the protrusion 6 on the mounting base 1. At this time, the coupling groove 7 on the mounting base 1 is exactly aligned with the socket 9, thereby further ensuring the convenience of disassembly and assembly of the connecting base 4 and the middle seat 2.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the outer wall of the arc-shaped end of the mounting base 1 is fixedly connected to multiple groups of mounting plates 4, and the multiple groups of mounting plates 4 are distributed in an arc shape, which are used to cooperate with the external fixing rod to realize the connection between the connecting base and the external side bearing member. The elastic component includes an inner plate 8 fixedly connected to the inner wall of the side seat 3, and the socket 9 is an I-shaped structure, and a spring 10 is fixedly connected between the inner plate 8 and the inner wall of the socket 9. After the rotating seat 11 is flush with the socket 9, the spring 10 pushes the socket 9 out of the side seat 3 and plugs into the inside of the coupling groove 7. The inner plate 8 and the inner wall of the side seat 3 are integrally formed. The limiting component includes a rotating seat 11 overlapped on the outer wall of the side seat 3, and the rotating seat 11 is rotatably connected to the outer wall of the socket 9 through a rotating shaft 13, and a pull ring 12 is fixedly connected to the side of the rotating seat 11 away from the rotating shaft 13. The socket 9 is maintained in the coupled and separated state with the coupling groove 7 by switching the shape of the rotating seat 11.

[0028] When the cam 11 is in the closed position, the spring 10 pushes the spring 11 to push the spring 12 out of the side seat 3 and insert it into the inner part of the coupling groove 7, and the cam 11 is coupled to the inner part of the side seat 3 under the linkage of the socket 9, thereby realizing the fixed connection between the cam 2 and the mounting base 1. Subsequently, it is only necessary to drive the socket 9 to separate the coupling groove 7 through the pull ring 12 to realize the independent disassembly of the cam 2, thereby ensuring the stable cooperation between the mounting base 1 and the cam 2 and improving the convenience of independent disassembly of the cam 2. In the process of sleeved on the front side of the mounting base 1, the axial position of the cam 2 is continuously switched until the card slot 5 is coupled with the protrusion 6 on the mounting base 1. At this time, the coupling groove 7 on the mounting base 1 is just aligned with the socket 9, thereby further ensuring the convenience of disassembly and assembly of the connecting base 4 and the cam 2.
