Description

Technical Field

[0001] This utility model relates to the field of gas detector technology, specifically a combustible gas detector. Background Technology

[0002] Combustible gas detectors are detectors that respond to the concentration of one or more combustible gases. There are two types of combustible gas detectors: catalytic and infrared optical. Catalytic combustible gas detectors use the change in resistance of a heated refractory platinum wire to determine the concentration of combustible gas. When combustible gas enters the detector, it causes an oxidation reaction on the surface of the platinum wire, and the heat generated raises the temperature of the platinum wire, thus changing its resistivity. Infrared optical detectors use infrared sensors to detect alkane combustible gases in the environment through the absorption principle of infrared light sources.

[0003] In practical use, since the detector and the connecting frame are fixedly connected, if the detector needs to be repaired, the entire structure needs to be disassembled, which may cause inconvenience in disassembly. Utility Model Content

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

[0026] Example 1:

[0027] Reference Figure 1-4A combustible gas detector includes a wall 1 and a detector body 2. A mounting base 3 is fixedly connected to the surface of the wall 1. The mounting base 3 has an inner cavity with a mounting groove 4. A first mounting component 5 is provided at the bottom of the mounting groove 4. The first mounting component 5 includes a first locking block 501 that is fixedly installed at the bottom of the inner cavity of the mounting groove 4. A first locking groove 502 that cooperates with the first locking block 501 is provided at the bottom of the mounting block 501. A second mounting component 6 is installed at the top of the mounting groove 4. The second mounting component 6 includes a movable block 601. A movable groove 602 is provided at the top of the inner cavity of the mounting base 3. The movable block 601 is located within the inner cavity of the movable groove 602. A second locking block 603 is fixedly connected to the bottom of the movable block 601. A second locking groove 603 that cooperates with the second locking block 603 is provided at the top of the mounting block 7. 4. A movable rod 605 is fixedly connected to the top of the movable block 601. A spring 606 is sleeved on the surface of the movable rod 605. An installation block 7 is fixedly connected to the surface of the detector body 2. The installation block 7 is located in the inner cavity of the installation groove 4. By setting the wall 1, the installation seat 3 can be installed on the wall 1. The installation seat 3 facilitates the installation of the detector body 2. The installation block 7 enters the installation groove 4. The bottom of the installation block 7 can be limited and fixed by the first installation component 5. Then, the top of the installation block 7 can be quickly installed and fixed by the second installation component 6. The combined use of the two can achieve the purpose of quick assembly and disassembly of the detector body 2, which facilitates the later maintenance of the detector body 2 and improves the convenience of maintenance.

[0028] Example 2:

[0029] Reference Figure 2 , Figure 3 and Figure 4 Both sides of the inner cavity of the movable groove 602 are provided with sliding grooves 8. A slider 9 is slidably connected to the inner cavity of the sliding groove 8. The end of the slider 9 away from the sliding groove 8 is fixedly connected to the movable block 601, which can limit and guide the movement of the movable block 601, increasing the stability of the movable block 601 when it moves. A handle 10 is fixedly connected to the top of the movable rod 605. The surface of the handle 10 is provided with anti-slip texture, which can facilitate the operation of the user and improve the convenience of disassembly and assembly. The detector body 2 is provided with an audible and visual alarm 11 and a sensor probe 12. When combustible gas enters the detector body 2 through the sensor probe 12, it will cause an oxidation reaction on the surface of the platinum wire inside the detector body 2, generating heat and raising the temperature of the platinum wire, thereby causing a change in the resistivity of the platinum wire, achieving the purpose of detecting combustible gas. The audible and visual alarm 11 will remind the staff to check in time and reduce the occurrence of danger.

[0030] The working principle is as follows:

[0031] In use, first fix the mounting base 3 on the wall 1, then take out the detector body 2 with one hand, and at the same time pull the handle 10 upward with the other hand. This will drive the movable block 601 and the second locking block 603 upward and into the movable slot 602. Then insert the mounting block 7 on the back of the detector body 2 into the mounting slot 4, and then push the detector body 2 downward so that the first locking block 501 enters the first slot 502, which can limit and fix the bottom of the mounting block 7. Finally, release the handle 10. At this time, the movable block 601 will be automatically pushed downward by the return force of the spring 606. The movement of the movable block 601 can push the second locking block 603 into the second slot 604, which can quickly install and fix the top of the mounting block 7. The combined use of the two can achieve the purpose of quick disassembly and assembly of the detector body 2, which is convenient for the later maintenance of the detector body 2 and improves the convenience of maintenance.

[0032] When combustible gas enters the detector body 2 through the sensor probe 12, it causes an oxidation reaction on the surface of the platinum wire inside the detector body 2, generating heat and raising the temperature of the platinum wire. This causes a change in the resistivity of the platinum wire, thus achieving the purpose of detecting combustible gas. The sound and light alarm 11 then alerts staff to check in time and reduce the occurrence of danger.

[0033] In summary, this combustible gas detector, by setting up a wall 1, allows the mounting base 3 to be installed on the wall 1. The mounting base 3 facilitates the installation of the detector body 2. The mounting block 7 enters the mounting groove 4. The bottom of the mounting block 7 is limited and fixed by the first mounting component 5, and the top of the mounting block 7 is quickly installed and fixed by the second mounting component 6. The combined use of the two components allows for quick assembly and disassembly of the detector body 2, facilitating future maintenance and improving maintenance convenience.
