[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1 - Figure 3 The specific embodiments of this utility model will be described in further detail.

[0022] Depend on Figure 1 - Figure 3 As shown, this utility model includes a detection box 1. To facilitate the carrying of the detector, an air pump 2 is provided inside the detection box 1. The air outlet of the air pump 2 is connected to a detector 3. The air inlet of the air pump 2 is connected to an air inlet pipe 4. A telescopic pipe 5 is connected to the front side of the air inlet pipe 4. The telescopic pipe 5 is a corrugated pipe. A rigid pipe 6 is connected to the front side of the telescopic pipe 5. A flared mouth 7 is connected to the front side of the rigid pipe 6. The flared mouth 7 and the telescopic pipe 5 cooperate to form an air intake detection structure. A rotatable cover plate 8 is provided on the front side of the detection box 1. Multiple buffer bags 9 are fixedly connected to the outer periphery of the detection box 1.

[0023] It should be noted that the detector 3 is a gas detector 3, and both it and the gas pump 2 are existing technologies, which will not be described in detail here;

[0024] In use, the buffer bladder 9 can protect the detection box 1 and its internal components. When the device is carried, the flared mouth 7 is retracted into the detection box 1 by the rigid tube 6. The cover plate 8 seals the opening on the front of the detection box 1 through which the flared mouth 7 protrudes. When gas detection is required, the flared mouth 7 can be extended forward. After the air pump 2 is started, gas detection can be performed through the detector 3. During the process of the flared mouth 7 extending forward, the cover plate 8 will also rotate downward. There will be no interference between the cover plate 8 and the flared mouth 7.

[0025] Furthermore, by Figure 1 - Figure 3 As shown, in order to improve the gas detection accuracy, multiple elastic plates 10 are fixedly connected to the inner side of the horn 7, and a ring 11 is fixedly connected to the inner side of the rigid tube 6. The rear side of each elastic plate 10 is fixedly connected to the ring 11.

[0026] Furthermore, by Figure 1 - Figure 3As shown, in order to make the device retract more smoothly, a guide sleeve 12 is fixedly connected inside the detection box 1. The telescopic tube 5 and the rigid tube 6 can move back and forth along the inside of the guide sleeve 12. A guide groove 13 is provided on the upper side of the guide sleeve 12. A guide block 14 is slidably connected inside the guide groove 13. The lower end of the guide block 14 is fixedly connected to the rigid tube 6.

[0027] Furthermore, by Figure 1 - Figure 3 As shown, in order to facilitate operation by staff, an adjustment plate 15 is rotatably connected to the upper side of the detection box 1, and a power plate 16 is fixedly connected to the lower side of the adjustment plate 15. A power groove 17 is provided in the middle of the power plate 16, and the upper side of the guide block 14 is slidably connected to the power groove 17. The power plate 16 rotates to form a structure in which the guide block 14 moves back and forth.

[0028] In use, when gas detection is required, the adjusting plate 15 can be rotated. The adjusting plate 15 will rotate through the power plate 16, and then under the action of the power groove 17, the guide block 14 will move forward along the guide groove 13. The guide block 14 drives the rigid tube 6 to move forward through the rigid tube 6, pushing the flare 7 out of the guide sleeve 12. During the process of the flare 7 extending forward out of the guide sleeve 12, since each elastic plate 10 is elastic, it will reset under the action of elasticity, opening the front side of the flare 7, thereby increasing the range of gas pumped by the air pump 2, and thus increasing the detection accuracy of the detector 3.

[0029] Furthermore, by Figure 1 - Figure 3 As shown, a power shaft 18 is fixedly connected to the lower side of the power plate 16, a first bevel gear 19 is fixedly connected to the lower side of the power shaft 18, a second bevel gear 20 is meshed with the front side of the first bevel gear 19, a rotating shaft 21 is fixedly connected to the front side of the second bevel gear 20, the rotating shaft 21 is rotatably connected to the detection box 1, and the front side of the rotating shaft 21 is fixedly connected to the cover plate 8.

[0030] When the adjusting plate 15 rotates, the power plate 16 will also drive the power shaft 18 to rotate, which in turn will drive the cover plate 8 to rotate under the action of the first bevel gear 19 and the second bevel gear 20.

[0031] Furthermore, by Figure 1 - Figure 3 As shown, a hanging hole 22 is provided on the cover plate 8 in order to enable the device to be used in a suspended manner;

[0032] When in use, after the cover plate 8 is rotated open, the device can be suspended through the suspension hole 22.

[0033] In use, this invention first protects the detection box 1 and its internal components through the buffer bladder 9. When the device is being carried, the flared mouth 7 retracts into the detection box 1 under the action of the rigid tube 6. The cover plate 8 seals the opening on the front of the detection box 1 through which the flared mouth 7 protrudes. When gas detection is required, the adjusting plate 15 can be rotated. The adjusting plate 15 rotates through the power plate 16, and then, under the action of the power groove 17, the guide block 14 moves forward along the guide groove 13. The guide block 14 drives the rigid tube 6 forward through the rigid tube 6, pushing the flared mouth 7 out of the guide sleeve 12. During the process of the flared mouth 7 extending forward out of the guide sleeve 12, due to each All elastic plates 10 are elastic and reset under the action of elastic force, opening the front side of the horn 7, thereby increasing the range of gas pumped by the air pump 2 and thus increasing the detection accuracy of the detector 3. When the adjusting plate 15 rotates, the power plate 16 will also drive the power shaft 18 to rotate, which in turn drives the cover plate 8 to rotate under the action of the first bevel gear 19 and the second bevel gear 20. After the air pump 2 is started, gas detection can be performed by the detector 3. As the horn 7 extends forward, the cover plate 8 will also rotate downward. There will be no interference between the cover plate 8 and the horn 7. When the cover plate 8 is rotated open, the device can be suspended through the suspension hole 22.

[0034] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively achieves the purpose of making the detector easy to carry, improving the accuracy of gas detection, making the device easier to retract, facilitating the operation of staff, and enabling the device to be used in a suspended manner.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
