[0002] Combustible gases are widely used in numerous settings, including industrial production and household life. However, leaks of combustible gases not only waste energy but can also trigger serious safety accidents such as fires and explosions, posing a significant threat to people's lives and property. Therefore, timely and accurate detection of combustible gas leaks is crucial.

[0003] Existing combustible gas leak detection equipment typically mounts the detection sensor at one end of a flexible rod, with the other end connected to a handheld terminal. During actual testing, the flexible rod needs to be frequently rotated to adjust the sensor's position for detecting different areas. However, prolonged and frequent rotation can easily lead to wear, breakage, and other damage to the flexible rod, affecting the normal operation of the equipment. Furthermore, when the flexible rod is damaged, due to the tight connections between the various parts of the equipment, it is difficult to replace quickly, increasing maintenance costs and downtime, and reducing detection efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] This utility model discloses a combustible gas leak detection device, according to the attached... Figure 1-3As shown, it includes a handheld terminal 1, a flexible rod 2 and a detection sensor 3. The detection sensor 3 changes the semiconductor resistance value through gas adsorption, converts the chemical signal into an electrical signal, and then senses the concentration of combustible gas in the air in real time. The detection sensor 3 is used to detect the concentration of combustible gas. An installation and removal unit 4 is provided between the handheld terminal 1 and the flexible rod 2.

[0039] Installation and removal unit 4 includes:

[0040] Insertion sleeve 41 is fixedly connected to the other end of flexible rod 2;

[0041] Plug-in block 42 is connected to handheld terminal 1;

[0042] Limiting component 43 is disposed on the plug-in block 42 and is used to fix the plug-in socket 41 and the plug-in block 42.

[0043] The pressing component 44 is located on one side of the limiting component 43 and is used to press the limiting component 43 to cancel the limiting effect. The installation and removal unit 4 enables rapid installation and removal between the handheld terminal 1 and the flexible rod 2. When the flexible rod 2 becomes damaged due to prolonged rotation, the operator can quickly remove the damaged flexible rod 2 from the handheld terminal 1 and replace it with a new one, greatly shortening the equipment's maintenance time and improving testing efficiency. Because the damaged flexible rod 2 can be quickly replaced, there is no need for large-scale repair or replacement of the entire equipment, reducing the cost of spare parts and labor required for maintenance and lowering the overall maintenance cost of the equipment.

[0044] According to the appendix Figure 1-2 As shown, the handheld terminal 1 is further provided with a display screen 11 on the front;

[0045] A button 12 is located below the display screen 11;

[0046] A charging port 13 is provided on the side of the handheld terminal 1;

[0047] A connector 14 is fixedly connected to the top of the handheld terminal 1.

[0048] According to the appendix Figure 1-3 As shown, the connector 14 is further fixedly connected to the plug block 42.

[0049] According to the appendix Figure 1-3 As shown, further, the socket 41 has an insertion interface 411, and positioning grooves 412 are provided on both sides of the insertion interface 411.

[0050] According to the appendix Figure 1-3As shown, further, the plug block 42 is plugged into the plug interface 411, and an electrical plug block 421 is fixedly connected to the top of the plug block 42. The electrical plug block 421 is plugged into the plug socket 41.

[0051] Positioning blocks 422 are fixedly connected to both sides of the plug-in block 42, and the positioning blocks 422 are slidably connected in the positioning groove 412.

[0052] According to the appendix Figure 1-4 As shown, furthermore, holes are provided on the side of the plug-in block 42;

[0053] Limiting component 43 includes:

[0054] Spring 431, one end of spring 431 is fixedly connected to the hole;

[0055] The limiting block 432 has one end fixedly connected to the other end of the spring 431, and the limiting block 432 is slidably connected in the hole. The end of the limiting block 432 is rounded so that during the insertion process, the limiting block 432 can be squeezed into the hole and can squeeze the spring 431 to retract.

[0056] According to the appendix Figure 1-4 As shown, the pressing component 44 further includes:

[0057] A fixing block is fixedly connected to the side of the plug-in socket 41;

[0058] The extrusion rod is slidably connected within the fixed block, and an annular block is sleeved on the extrusion rod and slidably connected within the fixed block.

[0059] A return spring is sleeved on the outside of the extrusion rod, and one end of the return spring is fixedly connected to the annular block. The return spring is used to reset the extrusion rod.

[0060] Working principle:

[0061] Align the plug-in block 42 with the plug interface 411 inside the plug-in sleeve 41, so that the positioning blocks 422 on both sides of the plug-in block 42 slide into the positioning grooves 412 on both sides of the plug interface 411, ensuring that the plug-in block 42 is accurately inserted into the plug-in sleeve 41. At the same time, the electrical plug 421 on the top of the plug-in block 42 is also inserted into the plug-in sleeve 41, realizing the electrical connection between the handheld terminal 1 and the detection sensor 3. When the plug-in block 42 is inserted to a certain depth, the limiting block 432 in the limiting assembly 43 pops out under the action of the spring 431 and locks into the corresponding limiting groove in the plug-in sleeve 41, thereby fixing the plug-in block 42 in the plug-in sleeve 41, completing the installation of the handheld terminal 1 and the flexible rod 2.

[0062] Pressing the squeezing rod in the pressing assembly 44 causes the squeezing rod to move inward and squeeze the limiting block 432 in the limiting assembly 43, causing the limiting block 432 to retract into the hole against the elastic force of the spring 431, thus canceling the limiting effect. At this time, the plug-in block 42 can be pulled out from the plug-in interface 411 under the action of external force, realizing the quick disassembly of the handheld terminal 1 and the flexible rod 2.
