Technical Field

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

[0002] A gas detector is a device used to detect whether there is a flammable gas leak in the air. Gas detectors can detect the danger of gas leaks in time and issue an alarm to help prevent safety accidents such as fires or explosions.

[0003] Utility model patent CN215833361U discloses a combustible gas detector. The key technical features are: it includes a gas detection port; the detection mechanism comprises a circuit board and a sensor disposed within the housing; and the sensor is mounted on the circuit board. This utility model, by fixing the sensor to the circuit board inside the combustible gas detector, prevents the sensor from easily falling off, thereby making the combustible gas detector safer and more reliable.

[0004] Regarding the above-mentioned content, the following technical defects exist: A household combustible gas detector is a device used to detect whether there is a combustible gas leak in the air. It can draw in ambient air through the gas detection port and perform gas detection, thereby sensing the concentration of combustible gas in the air. If the concentration reaches a certain level, the detector will trigger the alarm system to remind the user to pay attention to the gas leak problem. Usually, several screws are used to install the gas detector on the mounting plate. However, the stability of the installation using screws is poor. The screws may loosen, which will affect the stability of fixing the gas detector to the mounting plate. In addition, turning the screws requires the use of a screwdriver, which also makes the installation process of the gas detector complicated.

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

[0006] The purpose of this invention is to address the shortcomings of existing technologies that use screws for installation, such as poor stability, loosening of the screws affecting the stability of fixing the gas detector to the mounting plate, and the need for a screwdriver to rotate the screws, which complicates the installation process.

[0007] To solve the above-mentioned technical problems, this utility model provides a household combustible gas detector, comprising: a mounting plate, a gas detector body mounted on one side of the mounting plate, a gas detection port on the side of the gas detector body away from the mounting plate, a self-test button mounted on the side of the gas detector body away from the mounting plate, an adjustment device on the side of the mounting plate close to the gas detector body, the adjustment device including a connecting block, the connecting block being fixedly connected to one side of the mounting plate, the gas detector body being slidably connected to the inner wall of the connecting block, a limit block being fixedly connected to one side of the inner wall of the connecting block, an adjustment block being fixedly connected to one side of the connecting block, two adjustment holes being opened on the side of the adjustment block, a slider being slidably connected to the inner wall of the adjustment holes, a connecting strip being fixedly connected to one side of the slider, both connecting strips slidingly penetrating the inner wall of the connecting block, a plurality of connecting holes being opened on the side of the slider, the plurality of connecting holes being evenly distributed on the slider, a common top plate being fixedly connected to the side of the two connecting strips close to each other, and a rotating rod threaded through the inner wall of the adjustment block, the rotating rod being threadedly connected to the inner wall of the two connecting holes respectively.

It can draw in ambient air through the gas detection port and perform gas detection, thereby sensing the concentration of combustible gas in the air. If the concentration reaches a certain level, the detector will trigger the alarm system to remind the user to pay attention to the gas leak problem. Usually, several screws are used to install the gas detector body on the mounting plate. However, the stability of the installation using screws is poor, and the screws may loosen, affecting the stability of fixing the gas detector body to the mounting plate. In addition, turning the screws requires the use of a screwdriver, which also complicates the installation process. An adjustment device can replace the screws to fix the gas detector body to the mounting plate. The adjustment device can increase the speed of fixing the gas detector body and shorten the installation time.

[0009] Preferably, contact blocks are fixedly connected to both sides of the inner wall of the connecting block. The contact blocks are elastic blocks, and friction pads are fixedly connected to the sides of the two contact blocks that are close to each other.

[0010] The effect achieved by the above components is that when the gas detector body is placed on the inner wall of the connecting block, when the two sides of the gas detector body come into contact with the friction pads, the gas detector body will cause the contact block to deform, thereby improving the stability of the gas detector body within the connecting block through the contact block and the friction pads.

Detailed Implementation

[0031] 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.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 6 The household combustible gas detector provided in this embodiment includes: a mounting plate 1, a gas detector body 4 mounted on one side of the mounting plate 1, a gas detection port 5 opened on the side of the gas detector body 4 away from the mounting plate 1, a self-test button 6 mounted on the side of the gas detector body 4 away from the mounting plate 1, an adjustment device 2 provided on the side of the mounting plate 1 close to the gas detector body 4, and an auxiliary device 3 provided on the side of the gas detector body 4.

[0034] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The adjusting device 2 includes a connecting block 201, which is fixedly connected to one side of the mounting plate 1. The gas detector body 4 is slidably connected to the inner wall of the connecting block 201. A limit block 202 is fixedly connected to one side of the inner wall of the connecting block 201. An adjusting block 203 is fixedly connected to one side of the connecting block 201. Two adjusting holes 204 are opened on the side of the adjusting block 203. A slider 205 is slidably connected to the inner wall of the adjusting holes 204. A connecting strip 207 is fixedly connected to one side of the slider 205. Both connecting strips 207 slide through the inner wall of the connecting block 201. Several connecting holes 206 are evenly distributed on the side of the slider 205. Two connecting straps 207 are fixedly connected to the same top plate 208 on their adjacent sides. A rotating rod 209 is threaded through the inner wall of the adjusting block 203. The rotating rod 209 is threadedly connected to the inner walls of two connecting holes 206 respectively. The household combustible gas detector body 4 is a device used to detect whether there is a combustible gas leak in the air. It can draw in ambient air through the gas detection port 5 and perform gas detection, thereby sensing the concentration of combustible gas in the air. If the concentration reaches a certain level, the detector will trigger an alarm system to remind the user of the gas leak problem. Normally, several screws are used to install the gas detector body 4 on the mounting plate 1 for use. However, when using… The screw provides poor stability during installation and may loosen, affecting the stability of fixing the gas detector body 4 to the mounting plate 1. Furthermore, turning the screw requires a screwdriver, complicating the installation process. The adjusting device 2 can replace the screw to fix the gas detector body 4 to the mounting plate 1, increasing the speed of fixing and shortening the installation time. Contact blocks 210 are fixedly connected to both sides of the inner wall of the connecting block 201. Each contact block 210 is an elastic block, and friction pads 211 are fixedly connected to the side of each contact block 210 closest to each other. The gas detector body 4 is then placed inside the connecting block 201. When the gas detector body 4 contacts the friction pad 211 on both sides, the gas detector body 4 will cause the contact block 210 to deform. Thus, through the contact block 210 and the friction pad 211, the stability of the gas detector body 4 in the connecting block 201 can be improved. A limit ring 212 is fixedly connected to one side of the inner wall of the adjustment hole 204. The limit ring 212 can limit the movement of the slider 205 in the adjustment hole 204. An auxiliary block 213 is fixedly connected to the side of the slider 205 near the connecting strip 207. The auxiliary block 213 can increase the speed of adjusting the slider 205. The limit block 202 is a titanium alloy block. The limit block 202 made of titanium alloy is relatively hard and difficult to deform.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The auxiliary device 3 includes two positioning rods 31, both of which are fixedly connected to one side of the gas detector body 4. The arc surface of the positioning rod 31 is slidably connected to a locking block 32. The same protective plate 33 is fixedly connected to one side of the two locking blocks 32. A sliding rod 34 slides through the inner wall of the protective plate 33. A spring 35 is sleeved on one end of the arc surface of the sliding rod 34. The two ends of the spring 35 are fixedly connected to the protective plate 33 and the sliding rod 34 respectively. The sliding rod 34 is slidably connected to the inner wall of the gas detector body 4. When the self-test button 6 on the gas detector body 4 is not in use, it can be protected by the auxiliary device 3 to prevent the self-test button 6 from being damaged by physical impact, which would affect the subsequent self-test effect of the gas detector body 4. A fixing block 36 is fixedly connected to one end of the arc surface of the sliding rod 34. The fixing block 36 can improve the speed and efficiency of pulling the sliding rod 34.

[0036] The working principle of the household combustible gas detector provided by this utility model is as follows: Pull the top plate 208 upward. The movement of the top plate 208 will drive the connecting belt 207 to move, placing the gas detector body 4 on one side of the connecting block 201 and the limiting block 202. At this time, the gas detector body 4 can be limited by the connecting block 201 and the limiting block 202. Then, adjust the slider 205 in the adjusting hole 204. The movement of the slider 205 will drive the connecting belt 207 and the top plate 208 to move. Adjust the slider 205 to a suitable position, and then rotate the rotating rod 209 in the adjusting block 203. The rotating rod 209 can be connected to the connecting hole 206, and the slider 205 can be fixed in the adjusting hole 204 by rotating the rod 209. At this time, the top plate 208 can be fixed to one side of the gas detector body 4 by the connecting belt 207 installed on the slider 205. At this time, the task of fixing the gas detector body 4 is completed.

[0037] Pulling the sliding rod 34 causes the spring 35 to stretch, allowing the locking block 32 to be placed on one side of the positioning rod 31. Pressing the locking block 32 against the positioning rod 31 via the protective plate 33 will make the inside of the locking block 32 contact the positioning rod 31. Releasing the sliding rod 34 will cause the spring 35 to connect the sliding rod 34 to the inner wall of the gas detector body 4, thus fixing the protective plate 33 to one side of the self-test button 6.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] 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.
