Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model discloses an automatic combustible gas alarm device, comprising a horizontal plate 1 and a controller body 102. The controller body 102 is a combustible gas alarm controller, which can receive signals from a detection probe and display a measured value in real time. When the measured value reaches a set alarm value, the control host sends out an audible and visual alarm, and outputs a control signal (switch quantity contact output) at the same time, prompting the operator to take safety measures in time, or automatically start the control equipment connected in advance to ensure safe production. A mounting groove is provided on the top of the horizontal plate 1, and a connecting disk 101 is movably provided inside the mounting groove. The controller body 102 is fixedly provided on the inner wall of the connecting disk 101. Limiting grooves are provided on both sides of the connecting disk 101, and a limiting rod 2 is movably provided inside the limiting groove. A nut seat 201 is fixedly provided at one end of the limiting rod 2, a guide sleeve 204 is fixedly provided at the bottom of the nut seat 201, and a guide rod 205 is movably provided on the inner wall of the guide sleeve 204.

[0021] The connection relationship between the guide rod 205 and the guide sleeve 204 is a sliding connection, and the inner wall of the nut seat 201 is movably provided with a screw rod 202. The connection relationship between the screw rod 202 and the nut seat 201 is a threaded connection. One end of the screw rod 202 passes through one side of the inner wall of the horizontal plate 1 and extends to one side of the outer wall of the horizontal plate 1. A turning handle 203 is fixedly provided at one end of the screw rod 202. Vertical plates 5 are fixedly provided on both sides of the bottom of the horizontal plate 1, and a motor 501 is provided on one side of the vertical plate 5.

[0022] Specifically, the connection relationship between the limiting rod 2 and the connecting disk 101 is a movable plug-in connection.

[0023] In this embodiment, a limiting rod 2 is provided, and the screw rod 202 is driven to rotate by turning the handle 203. The rotating screw rod 202 cooperates with the nut seat 201 through the thread, so that the nut seat 201 and the limiting rod 2 are laterally displaced. When one end of the limiting rod 2 is inserted into the limiting groove on the connecting disk 101, the connecting disk 101 can be limited.

[0024] Specifically, guide fans 4 are provided on both sides of the bottom of the transverse plate 1 .

[0025] In this embodiment, by setting up a guide fan 4, the guide fan 4 can attract the surrounding air and guide it to the bottom of the controller body 102. The controller body 102 can then detect the air flowing through. When combustible gas is detected, the controller body 102 will issue an audible and visual alarm.

[0026] Specifically, the output shaft of the motor 501 is fixedly connected to the bidirectional screw 502, and threaded sleeves 503 are movably provided on both sides of the bidirectional screw 502. The connection relationship between the threaded sleeve 503 and the bidirectional screw 502 is a threaded connection. The two sides of the bidirectional screw 502 are symmetrically provided with threads in opposite directions, and a clamping plate 504 is fixedly provided on the bottom of the threaded sleeve 503.

[0027] In this embodiment, a motor 501, a bidirectional screw 502, a threaded sleeve 503 and a clamping plate 504 are provided. The motor 501 drives the bidirectional screw 502 to rotate, and the rotating bidirectional screw 502 drives the clamping plates 504 on both sides to move through the threaded sleeve 503, so that the device body can be installed on a narrow wall or desktop through the clamping plates 504.

[0028] Specifically, a slider 506 is fixedly provided on the top of the threaded sleeve 503 , a slide bar 507 is movably provided on the inner wall of the slide bar 506 , and the connection relationship between the slide bar 507 and the slide bar 506 is a sliding connection.

[0029] In this embodiment, by providing a slider 506 and a slide rod 507 , the threaded sleeve 503 can be guided so that the threaded sleeve 503 and the clamping plate 504 can move stably.

[0030] Specifically, an anti-slip pad 505 is fixedly provided on one side of the clamping plate 504 .

[0031] In this embodiment, by providing the anti-skid pad 505 , the anti-skid pad 505 can enhance the friction of the clamping plate 504 , so that the clamping plate 504 is not prone to slipping.

[0032] When in use, the guide fan 4 is started, and the guide fan 4 can draw the surrounding air and guide it to the bottom of the controller body 102. The controller body 102 can then detect the air flowing through. When combustible gas is detected, the controller body 102 will give an audible and visual alarm prompt;

[0033] When disassembling the controller body 102, the screw rod 202 is driven to rotate by turning the handle 203. The rotating screw rod 202 makes the nut seat 201 and the limiting rod 2 move laterally through the threaded fit between the screw rod 202 and the nut seat 201. When one end of the limiting rod 2 is moved out of the limiting groove on the connecting disk 101, the restriction on the connecting disk 101 can be released, and then the controller body 102 can be quickly disassembled;

[0034] When installing the controller body 102, insert the connecting disk 101 on the controller body 102 into the installation groove on the horizontal plate 1, and drive the screw rod 202 to rotate by turning the handle 203. The rotating screw rod 202 cooperates with the nut seat 201 through the thread, so that the nut seat 201 and the limiting rod 2 are laterally displaced. When one end of the limiting rod 2 is inserted into the limiting groove on the connecting disk 101, the connecting disk 101 can be limited, thereby realizing the installation of the controller body 102.

[0035] To sum up, the combustible gas automatic alarm device, by setting a limit rod 2, a nut seat 201, a screw rod 202 and a turning handle 203, drives the screw rod 202 to rotate by turning the turning handle 203, and the rotating screw rod 202 makes the nut seat 201 and the limit rod 2 move laterally through the threaded cooperation with the nut seat 201. When one end of the limit rod 2 is moved out of the limit groove on the connecting disk 101, the restriction on the connecting disk 101 can be released, and then the controller body 102 can be quickly disassembled. Since the clamping method is used instead of the traditional bolt connection, the staff does not need to use disassembly tools during the disassembly process, the disassembly time is short, and the disassembly efficiency is high.
