[0002] Fire is one of the major disasters that frequently occur in people's daily lives, seriously threatening human life and property safety. With the rapid development of urbanization and the increasing concentration of people, gas has entered thousands of households. While bringing convenience to our lives, it also increases many safety hazards.

[0003] There are many factors that cause household fires, including explosions caused by gas leaks, improper use of electricity or aging appliances, improper storage of flammable materials, improper use of gas or stoves, and smoking. Most existing detection devices can simultaneously detect smoke fires and gas leaks. Their main body is composed of an optical and smoke maze composite cavity shell, a bottom shell, and a circuit board. At the same time, a laser light source and detector are installed on one of the bottom shells. The problems encountered in actual use are:

[0004] The cavity shell and the bottom shell are mostly connected by threads or snaps, which is not conducive to the rapid disassembly and assembly of the various parts when problems occur. At the same time, the connection between the shell structures is simple and the protection is poor, making it difficult to protect internal devices such as internal detectors.

[0005] Therefore, the utility model proposes a laser gas and smoke composite measurement device. Utility Model Content

[0006] In response to the defects in the existing technology, the utility model provides a laser gas and smoke composite measurement device that can solve the following problems:

[0012] Furthermore, the front mounting seat is vertically arranged in an "L" shape as a whole, and the rear mounting seat is horizontally arranged in a rectangular shape. Both are connected by an axis and a base, and the outer protective tube is horizontally arranged as a whole.

[0013] Furthermore, a circular air inlet is formed through the surface of the front end mounting seat.

[0014] Furthermore, a circular waterproof and breathable layer is provided inside the first front cover, the connecting end of the second front cover and the cavity body is set as a magnetic port, and two groups of sealing protrusions are arranged in an arc shape along the edges on both sides of the connecting end of the second front cover and the cavity body, and are distributed in an inclined and staggered manner, and the connecting ends of the cavity body and the second front cover are correspondingly provided with arc-shaped fitting openings, which are also set as magnetic ports.

[0015] Furthermore, the sealing ring is configured as a rubber sealing ring, which is configured in a flat shape and is entirely configured on the inner side of the connecting end between the second front cover and the cavity body.

[0016] Furthermore, the inner protective tube and the tailstock are threadedly connected, and the inner protective tube and the outer protective tube are movably sleeved.

[0017] From the above technical solution, it can be seen that the beneficial effects of the utility model are:

[0027] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0028] See Figure 1-3 As shown, a laser gas and smoke sensor composite measurement device includes a base 1 and a front mounting seat 2 and a rear mounting seat 3 movably connected at both ends. A front cover assembly 4 is fixedly connected to the inner side of the front mounting seat 2, and an outer protective tube 5 is fixedly connected to the top of the rear mounting seat 3. A rear cover assembly 6 is embedded in the outer protective tube 5. A cavity body 7 and a tailstock 10 are fixedly mounted between the front cover assembly 4 and the rear cover assembly 6.

[0029] The front cover assembly 4 includes a first front cover 8 and a second front cover 9 that are fixedly connected. A sealing ring 14 is embedded on the inner side of the second front cover 9, and a sealing protrusion 15 is fixedly provided on the outer side of the second front cover 9. The rear cover assembly 6 includes an inner protective tube 11, a circuit board 12 therein, and an inner mounting plate 13.

[0030] In the embodiment of the present invention, the front end mounting seat 2 is vertically arranged in an "L" shape as a whole, and the rear end mounting seat 3 is horizontally arranged in a rectangular shape. Both are connected by flipping the shaft and the base 1. The outer protective tube 5 is horizontally arranged as a whole, and a circular air inlet is opened through the surface of the front end mounting seat 2. The front end mounting seat 2 and the rear end mounting seat 3 are used to facilitate the flipping and adjustment of the corresponding front cover assembly 4 and rear cover assembly 6. The outer protective tube 5 is used to protect the rear cover assembly 6 and at the same time provide guidance for the rear cover assembly 6 as a whole.

[0031] A circular waterproof and breathable layer is provided inside the first front cover 8, and the connecting end of the second front cover 9 and the cavity body 7 is set as a magnetic port. The sealing protrusions 15 are arranged in two groups in an arc shape along the edges on both sides of the connecting end of the second front cover 9 and the cavity body 7, and are distributed in an inclined and staggered manner. The connecting ends of the cavity body 7 and the second front cover 9 are correspondingly provided with arc-shaped fitting openings, which are also set as magnetic ports. The sealing ring 14 is set as a rubber sealing ring, which is flat and is arranged as a whole on the inner side of the connecting end of the second front cover 9 and the cavity body 7. The sealing ring 14 enhances the sealing effect of the connecting end of the second front cover 9 and the cavity body 7, and the second front cover 9 and the cavity body 7 are set as magnetic through the interface end to achieve the effect of sealing between the two.

[0032] When disassembling and assembling the front cover assembly 4, the user flips the front end mounting seat 2, and the front end mounting seat 2 drives the front cover assembly 4 as a whole to separate from the cavity body 7. When the front cover assembly 4 contacts the cavity body 7, as the front end mounting seat 2 is flipped, the magnetic suction port end of the second front cover 9 contacts the magnetic suction port end of the cavity body 7 for magnetic sealing. At the same time, the sealing protrusion 15 and the mating port at the connecting end of the cavity body 7 are mated, effectively ensuring the sealing of the front cover assembly 4 and the cavity body 7.

[0033] The inner protective tube 11 and the tailstock 10 are threadedly connected, and the inner protective tube 11 and the outer protective tube 5 are movably sleeved. The inner protective tube 11 can enclose and protect the inner mounting plate 13 and the circuit board 12, and can also quickly disassemble and assemble the inner mounting plate 13 and the circuit board 12.

[0034] The surface of the inner mounting plate 13 is equipped with a detector and a laser light source, which are electrically connected to the circuit board 12. When disassembling and assembling the rear cover assembly 6, the user rotates the inner protective cylinder 11 from the tail end position, and the inner protective cylinder 11 separates from the tail stock 10 as it rotates. At the same time, the inner protective cylinder 11 gradually extends out of the outer protective cylinder 5, so that the rear cover assembly 6 as a whole is separated from the cavity body 7. When in use, the circuit between the circuit board 12 and the inner mounting plate 13 is connected, and then the rear cover assembly 6 as a whole is connected to the cavity body 7.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
