[0002] Toxic gas detectors are usually used in complex environments such as the oil mining industry, chemical plants or confined spaces where there is moisture and toxic gases may exist. By connecting one end of the sensor to the gas to be tested, the gas to be tested will generate a current signal related to it during the redox reaction with the working electrode. The toxic gas detector can sample the electrical signal on the sensor, and after internal data processing, it outputs a 4-20mA current signal or Modbus bus signal corresponding to the gas concentration in the surrounding environment, thereby obtaining the concentration of the gas to be tested.

[0003] Existing toxic gas detectors are generally fixed on the wall in the space by fasteners such as bolts, but this installation method is cumbersome and increases the time that workers stay in the dangerous area. If the concentration of toxic gas in the area exceeds the standard, it is easy to affect the health of the workers. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] In the technical scheme, a fixed toxic gas detector comprises a toxic gas detector 1 and a mounting base 2, a plug-in plate 3 is mounted on the side wall of the toxic gas detector 1, a slot 4 is opened on the upper wall of the mounting base 2, and the plug-in plate 3 is inserted and installed in the slot 4;

[0024] A magnet 5 is installed on the side wall of the mounting base 2, and the magnet 5 can be adsorbed on an external metal object. A placement groove 6 is opened on the side wall of the mounting base 2, and a buffer mechanism 7 is inserted and installed in the placement groove 6. The buffer mechanism 7 is fitted with the side wall of the toxic gas detector 1;

[0025] The buffer mechanism 7 includes a rubber pad 71, a cavity 72, an elastic element 73 and a top holding plate 74. The rubber pad 71 is inserted and installed in the placement groove 6. The side wall of the rubber pad 71 is provided with a cavity 72. The side wall of the elastic element 73 is provided with a top holding plate 74. The elastic element 73 and the top holding plate 74 are respectively connected to the left and right ends of the inner wall of the cavity 72.

[0026] In this technical solution, since the side wall of the mounting base 2 is provided with a magnet 5, the mounting base 2 can be conveniently fixed on an external metal object through the magnet 5, and because it is fixed by the magnet 5, the position of the mounting base 2 can be conveniently adjusted to change the position of the poison detector 1;

[0027] The toxic gas detector 1 and the mounting base 2 are connected by plugging, so when installing the toxic gas detector 1, it is only necessary to insert the plug board 3 into the slot 4, which is very convenient and greatly shortens the staff's stay time in the dangerous area to prevent danger;

[0028] The toxic gas detector 1 proposed in this article is a prior art, so its working process and principle will not be described in detail in this article. The model of the toxic gas detector 1 in this article is EA900, but it is not limited to this model.

[0029] In some technical solutions, a slide groove 8 is provided on the upper wall of the mounting base 2, and the slide groove 8 is connected to the slot 4. A push plate 9 is slidably installed in the slide groove 8, and a spring piece 10 is installed on the lower wall of the push plate 9. The cross-section of the spring piece 10 is V-shaped, and a positioning pin 11 is installed at one end of the spring piece 10 away from the push plate 9. A positioning hole 12 is provided on the side wall of the plug plate 3, and the positioning pin 11 can be inserted and installed in the positioning hole 12.

[0030] In this technical solution, the spring 10 is a metal spring. When the push plate 9 is pressed downward, the spring 10 will move downward in the slide groove 8, causing one side of the positioning pin 11 to contract inward, thereby causing the positioning pin 11 to disengage from the positioning hole 12, thereby releasing the fixation of the plug-in plate 3, so that the toxic gas detector 1 can be smoothly removed from the mounting base 2.

[0031] In some technical solutions, the elastic element 73 includes a telescopic tube 13 and a spring 14 , the supporting plate 74 is installed on the side wall of the extended end of the telescopic tube 13 , and the spring 14 is installed inside the telescopic tube 13 .

[0032] In this technical solution, when the toxic gas detector 1 is subjected to external impact, the buffer mechanism 7 can provide a buffer to prevent the toxic gas detector 1 from being in hard contact with the mounting base 2, thereby preventing the toxic gas detector 1 from being damaged;

[0033] The elasticity of the rubber pad 71 can be improved by providing the elastic element 73 .

[0034] In some technical solutions, a sound and light alarm 15 is installed on the side wall of the toxic gas detector 1, and the sound and light alarm 15 is electrically connected to the processor inside the toxic gas detector 1. The side wall of the toxic gas detector 1 is provided with an input and output line port 16.

[0035] In some technical solutions, a dustproof sealing mechanism 17 is inserted and installed inside the inlet and outlet port 16. The dustproof sealing mechanism 17 includes a rubber plug 171, a through hole 172 and a convex ring 173. The rubber plug 171 is inserted and installed in the inlet and outlet port 16. The outer side of the rubber plug 171 is provided with a convex ring 173. The inner wall of the inlet and outlet port 16 is provided with an annular groove 18. The convex ring 173 can be inserted and installed in the annular groove 18. The side wall of the rubber plug 171 is provided with a through hole 172.

[0036] In this technical solution, the dustproof sealing mechanism 17 can prevent dust and other impurities from entering the interior of the toxic gas detector 1 through the inlet and outlet ports 16, thereby extending the service life of the detector.

[0037] In some technical solutions, the cross-section of the through hole 172 is conical.

[0038] In this technical solution, the opening of the through hole 172 at one end located on the inner side of the input and output port 16 is larger, while the opening of the end located on the outer side of the input and output port 16 is smaller. When the data cable is inserted into the through hole 172, the outer wall of the data cable will fit tightly with the inner wall of the through hole 172, ensuring that dust cannot enter the harmful gas detector 1.

[0039] Working principle: The toxic gas detector 1 and the mounting base 2 are connected by plugging, so when installing the toxic gas detector 1, it is only necessary to insert the plug board 3 into the slot 4, which is very convenient and greatly shortens the staff's stay time in the dangerous area to prevent danger;

[0040] When the toxic gas detector 1 needs to be removed from the mounting base 2, the push plate 9 can be pressed downward, and the spring 10 will move downward in the slide groove 8, causing one side of the positioning pin 11 to contract inward, thereby causing the positioning pin 11 to disengage from the positioning hole 12, thereby releasing the fixation of the plug-in plate 3, so that the toxic gas detector 1 can be smoothly removed from the mounting base 2.
