These devices are widely used in industries, laboratories, mines, fire fighting, environmental monitoring, and other fields.

[0003] Utility model patent application CN222545318U discloses a gas detector. The key technical features are: a housing with an interconnected explosion-proof cavity and an opening; a connecting plate detachably disposed at the opening, capable of sealing the opening and forming an explosion-proof structure with the housing; a first circuit board fixed to the connecting plate near the housing, disposed within the explosion-proof cavity; and a detection component detachably disposed on the connecting plate away from the housing, having a detection cavity and a sensor body. The sensor body is located within the detection cavity and is used to detect gas. The sensor body is electrically connected to the first circuit board, and the detection cavity and explosion-proof cavity are independently configured. This technical solution solves the problem of sensors in existing gas detectors being inconvenient for maintenance and replacement by personnel.

[0004] Regarding the above-mentioned content, the following technical defects exist: Gas detectors, in conjunction with sensors, can detect the concentration of gases in the air. Gas detectors are typically used to monitor toxic, harmful, flammable, or oxygen-deficient gases. Usually, when installing a gas detector, it is fixed to a mounting rod using several screws and retainers. However, the installation stability using screws is poor. After a long period of time, the screws, through the retainers, can loosen, thus affecting the stability of the screws in fixing the gas detector to the mounting rod.

[0005] Therefore, it is necessary to provide a new systematic gas detector to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a systematic gas detector, including: a mounting rod, a gas detector body mounted on one side of the mounting rod, a sensor mounted on one side of the gas detector body, an adjustment device provided on the arc surface of the mounting rod near the gas detector body, the adjustment device including a fixing block, the fixing block being fixedly connected to the arc surface of the mounting rod, adjustment holes being provided on both sides of the fixing block, a connecting rod slidingly penetrating the inner wall of the adjustment hole, a contact block being fixedly connected to one end of the arc surface of the connecting rod, a first spring being sleeved on the other end of the arc surface of the connecting rod, the two ends of the first spring being fixedly connected to the connecting rod and one side of the fixing block respectively, two contact blocks being slidably connected to the inner wall of the fixing block, a connecting block being slidably connected to one side of the two contact blocks, the connecting block being fixedly connected to one side of the gas detector body, a limit rod slidingly penetrating the inner wall of the fixing block, the limit rod slidingly penetrating the inner wall of the connecting block, a second spring being sleeved on one end of the arc surface of the limit rod, the two ends of the second spring being fixedly connected to the limit rod and one side of the fixing block respectively.

[0008] The aforementioned components achieve the following effect: the gas detector body, in conjunction with the sensor, can detect the concentration of gases in the air.

Usually, when installing the gas detector body, several screws and retainers are used to fix it to the mounting rod. However, the installation stability using screws is poor. Over time, the screws, passing through the retainers to fix the gas detector body to the mounting rod, can loosen, affecting the stability of the screws in fixing the gas detector body to the mounting rod. In this case, an adjustment device can be used to replace the screws and retainers to fix the gas detector body to the mounting rod, improving the stability of fixing the gas detector body to the mounting rod.

[0009] Preferably, an auxiliary block is fixedly connected to one end of the arc surface of the limiting rod, and the auxiliary block is funnel-shaped.

[0011] Preferably, a pull ring is rotatably connected to the inner wall of the limiting rod.

[0012] The effect achieved by the above components is that the pull ring can increase the speed at which the limit rod is pulled.

[0013] Preferably, the connecting rod is a titanium alloy rod.

[0014] The above-mentioned components achieve the following effects: the surface of the titanium alloy connecting rod is not easily deformed, resulting in a longer service life.

[0015] Preferably, an auxiliary device is provided on the side of the gas detector body near the sensor. The auxiliary device includes a protective shell, which is slidably connected to the arc surface of the sensor. A positioning block is fixedly connected to one end of the arc surface of the protective shell. A rotating rod is threaded through the inner wall of the positioning block. An adjusting block is threaded to one end of the arc surface of the rotating rod. A fixing ring is fixedly connected to one side of the adjusting block. The inner wall of the fixing ring is fixedly connected to the arc surface of the gas detector body.

[0016] The effect achieved by the above components is that the sensor on the gas detector body is relatively fragile. The auxiliary device can be installed at the position of the sensor to protect the sensor surface and prevent the sensor from being damaged by impact.

[0017] Preferably, a plurality of anti-slip grooves are provided at one end of the arc surface of the rotating rod, and the plurality of anti-slip grooves are evenly distributed on the rotating rod.

[0018] The effect achieved by the above components is that the anti-slip sleeve can increase the friction on the surface of the rotating rod.

[0019] Preferably, the arc surface of the protective shell has several ventilation holes.

[0020] The effect achieved by the above components is that the vents allow gas to enter the protective shell more effectively.

[0021] Compared with related technologies, the systematic gas detector provided by this utility model has the following advantages:

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 4 The system gas detector provided in this embodiment includes: a mounting rod 1, a gas detector body 4 mounted on one side of the mounting rod 1, a sensor 5 mounted on one side of the gas detector body 4, an adjustment device 2 provided on the arc surface of the mounting rod 1 near the gas detector body 4, and an auxiliary device 3 provided on the side of the gas detector body 4 near the sensor 5.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The adjusting device 2 includes a fixing block 201, which is fixedly connected to the arc surface of the mounting rod 1. Adjusting holes 202 are provided on both sides of the fixing block 201. A connecting rod 203 slides through the inner wall of the adjusting hole 202. A contact block 205 is fixedly connected to one end of the arc surface of the connecting rod 203, and a first spring 204 is sleeved on the other end of the arc surface of the connecting rod 203. Both ends of the first spring 204 are fixedly connected to the connecting rod 203 and one side of the fixing block 201, respectively. Both contact blocks 205 are slidably connected to the inner wall of the fixing block 201. A connecting block 206 is slidably connected to one side of the contact block 205. The connecting block 206 is fixedly connected to one side of the gas detector body 4. A limiting rod 207 slides through the inner wall of the fixing block 201. The limiting rod 207 slides through the inner wall of the connecting block 206. A second spring 208 is sleeved on one end of the arc surface of the limiting rod 207. The two ends of the second spring 208 are fixedly connected to the limiting rod 207 and one side of the fixing block 201, respectively. The gas detector body 4, in conjunction with the sensor 5, can detect the concentration of gas in the air. The gas detector body 4 is typically used to monitor toxic substances. For gases that are harmful, flammable, or oxygen-deficient, the gas detector body 4 is typically fixed to the mounting rod 1 using several screws and retainers. However, using screws results in poor installation stability. Over time, the screws, passing through the retainers, can loosen, affecting the stability of the gas detector body 4. In this case, the adjusting device 2 can replace the screws and retainers to secure the gas detector body 4 to the mounting rod 1. On the mounting rod 1, the stability of fixing the gas detector body 4 to the mounting rod 1 can be improved by adjusting the device 2. An auxiliary block 209 is fixedly connected to one end of the arc surface of the limiting rod 207.

A pull ring 210 is rotatably connected to the inner wall of the limiting rod 207. The pull ring 210 can improve the speed of pulling the limiting rod 207. The connecting rod 203 is a titanium alloy rod. The surface of the titanium alloy connecting rod 203 is not easily deformed and has a good service life.

[0033] In the embodiments of this utility model, please refer to Figure 4The auxiliary device 3 includes a protective shell 31, which is slidably connected to the arc surface of the sensor 5. A positioning block 32 is fixedly connected to one end of the arc surface of the protective shell 31. A rotating rod 35 is threaded through the inner wall of the positioning block 32. An adjusting block 33 is threaded to one end of the arc surface of the rotating rod 35. A fixing ring 34 is fixedly connected to one side of the adjusting block 33.

The auxiliary device 3 can be installed at the position of the sensor 5. The auxiliary device 3 can protect the surface of the sensor 5 and prevent the sensor 5 from being damaged by impact. Several anti-slip grooves 36 are opened at one end of the arc surface of the rotating rod 35. The anti-slip grooves 36 are evenly distributed on the rotating rod 35. The anti-slip grooves can improve the friction of the surface of the rotating rod 35. Several vent holes 37 are opened on the arc surface of the protective shell 31. The vent holes 37 can better allow gas to enter the protective shell 31.

[0034] The working principle of the system gas detector provided by this utility model is as follows: Pulling the limiting rod 207 causes the second spring 208 to stretch. At this time, the connecting block 206 and the inner wall of the fixing block 201 can be pressed through the gas detector body 4. The connecting block 206 will contact one side of the contact block 205 through the inner wall of the fixing block 201. The contact between the connecting block 206 and the contact block 205 will cause the connecting rod 203 to slide in the adjusting hole 202. The movement of the connecting rod 203 will cause the first spring 204 to stretch. When the connecting block 206 is in the fixing block 201, the limiting rod 207 can be released. The second spring 208 will reset and cause the limiting rod 207 to connect with the inner wall of the connecting block 206. At this time, the gas detector body 4 can be fixed on the mounting rod 1.

[0035] Connect the inner wall of the protective shell 31 to the surface of the sensor 5. Then, rotate the rotating rod 35 inside the positioning block 32. The rotating rod 35 will move in the direction of the adjusting block 33. Connect the rotating rod 35 to the inner wall of the adjusting block 33. At this time, the protective shell 31 can be fixed on the sensor 5 by rotating the rod 35.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
