DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the embodiments:

[0024] like Figure 1-4 As shown, the utility model provides a gas leakage detection device, including a shell 1, the four outer corners of the shell 1 are symmetrically fixedly connected with ear seats 2, the middle of the ear seat 2 is movably inserted with a mounting screw 3, the inside of the shell 1 is movably installed with a detector 4, the upper front side of the detector 4 is fixedly installed with a display screen 5, the lower front side of the detector 4 is fixedly connected with a fixed button 6, the left and right sides of the shell 1 are symmetrically arranged with moving components 7, the front end of the moving component 7 is installed with a mounting mechanism 8, the middle of the left and right ends of the detector 4 are symmetrically fixedly installed with side panels 9, the middle of the lower end of the detector 4 is fixedly installed with a gas sensor 10, the middle of the lower end of the shell 1 is provided with a card slot 11, and the left and right inner walls of the shell 1 are symmetrically provided with connecting slots 12.

[0025] The side plate 9 matches with the connection slot 12 and is movably connected thereto, and the gas sensor 10 matches with the card slot 11 and is movably connected thereto.

[0026] Through the installation mechanism 8, the positioning column 86 can be inserted into the positioning hole 87 on the side plate 9, so that the detector 4 can be fixed, which also facilitates the disassembly of the detector 4, and further facilitates the inspection and replacement of the detector 4, thereby improving the practicality of the detector 4.

[0027] like Figure 3As shown, the moving component 7 includes a slide groove 71, and the slide grooves 71 are symmetrically opened on the left and right sides of the front end of the shell 1, and an electromagnet 72 is fixedly installed on the inner top of the slide groove 71, and a spring 73 is sleeved on the outside of the electromagnet 72. Guide grooves 74 are symmetrically opened on the left and right inner walls of the slide groove 71, and a slider 75 is slidably connected inside the slide groove 71. A fixed magnet 76 is fixedly installed on the top of the slider 75, and guide blocks 77 are symmetrically fixedly installed on the left and right ends of the slider 75.

[0028] One end of the spring 1 73 is fixedly connected to the top inner wall of the slide groove 71 , and the other end is fixedly connected to the top of the slider 75 . The electromagnet 72 and the fixed magnet 76 are both arranged outside the spring 1 73 .

[0029] The guide block 77 is slidably connected to the guide groove 74 .

[0030] When the electromagnet 72 is energized, the fixed magnet 76 can be attracted to move, so that the fixed magnet 76 drives the slider 75 to move synchronously, thereby fixing the slider 75. When the electromagnet 72 is not energized, the compressed spring 73 pushes the fixed magnet 76 and the slider 75 to move toward the side plate 9. At the same time, when the slider 75 moves, it drives the guide block 77 to slide synchronously in the guide groove 74, thereby avoiding the slider 75 from deviating.

[0031] like Figure 4 As shown, the mounting mechanism 8 includes a bracket 81, the bottom end of the bracket 81 is fixedly connected to the front end of the slider 75, a slide rod 82 is slidably connected to the middle of the front end of the bracket 81, a pull plate 83 is fixedly installed on the top of the slide rod 82, a limit plate 84 is fixedly installed on the bottom end of the slide rod 82, a spring 85 is sleeved on the outside of the bottom end of the slide rod 82, a positioning column 86 is fixedly installed on the bottom end of the limit plate 84, and positioning holes 87 are symmetrically opened at the upper and lower ends of the side plate 9.

[0032] One end of the second spring 85 is fixedly connected to the front end of the limiting plate 84 , and the other end is fixedly connected to the inner wall of the front end of the bracket 81 .

[0033] The positioning column 86 matches the positioning hole 87 and is movably connected.

[0034] After the spring 2 85 is compressed, it can push the limit plate 84 and the slide rod 82 downward under its own action, so that the positioning column 86 at the lower end of the limit plate 84 is inserted into the positioning hole 87, thereby limiting the side plate 9 and fixing the detector 4 to prevent the detector 4 from falling off.

[0035] The working principle of the gas leak detection device is described in detail below.

[0036] like Figure 1-4As shown, when the gas leak detection device is in use, the housing 1 can first be installed at a designated position near the gas pipeline by installing screws 3, and then the side panels 9 at both ends of the detector 4 are engaged with the connecting grooves 12 at both ends of the housing 1, and at the same time, the slider 75 can drive the bracket 81 to slide toward the side panel 9, and then under the elastic action of the spring 2 85, the slide bar 82 and the limit plate 84 will be driven to move downward, so that the limit plate 84 drives the positioning column 86 to be inserted into the positioning hole 87 on the side panel 9, so that the detector 4 can be limited and fixed. At this time, the gas sensor 10 can detect low-concentration combustible gas in its surrounding environment, which is convenient for detecting whether the gas is leaking. When the detector 4 is damaged, it only needs to pull the pull plate 83 outward to make it The pulling plate 83 drives the positioning column 86 to move synchronously through the sliding rod 82 and the limit plate 84, so that the positioning column 86 is separated from the positioning hole 87, so that the side plates 9 on both sides of the detector 4 will not fit with the connecting groove 12, and then the electromagnet 72 starts to be energized. At this time, the electromagnet 72 has magnetism, so that the fixed magnet 76 can be adsorbed and moved, so that the fixed magnet 76 drives the slider 75 to move synchronously, so that the slider 75 drives the bracket 81 to move away from the side plate 9. At this time, the spring 73 set begins to be compressed and deformed, so that the bracket 81 will not block the side plate 9, so that the detector 4 can be easily removed from the inside of the shell 1 for maintenance and replacement, without the need to drill holes again for installation, thereby improving the practicability of the device.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
