Preferably, a rear cover in threaded fit with the tail end of the hollow pipe body at the tail section of the outer shell is installed at the tail end of the hollow pipe body.

The beneficial effects of the utility model reside in that:

(1) the outer shell with the telescopic sleeve structure can control the length of the outer shell according to actual conditions, and is suitable for detecting gas alarm devices at any position;

(2) the outer shell with the telescopic sleeve structure is convenient to carry when not in use;

(3) the limiting baffle ring is arranged to prevent the hollow pipe body from sliding out of the tail part, the center of the limiting baffle ring can extend out of the air pipe interface, and the air pipe interface is communicated with the origin through an external air hose after extending out;

(4) under the condition of not using, the rear cover can seal the tail end of the outer shell, and the air pipe interface is collected into the outer shell.

The utility model discloses simple structure, convenient and practical can be suitable for the gaseous alarm device's of various positions detection to portable.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the present invention.

In the figure: 1. an outer housing; 2. a gas dispersion port; 3. a fixing plate; 4. a tracheal tube interface; 5. an air tube; 6. a limit stop ring; 8. an air hose; 9. and (4) a gas source.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Examples

As shown in fig. 1 and fig. 2, the present embodiment provides a short-term test instrument for gas alarm device, include the shell body 1 that constitutes telescopic tube structure by several sections of hollow body, head end department fixedly connected with gas dispersion mouth 2 of the hollow body that is located the first section of shell body, tail end department that is located the hollow body of first section installs fixed plate 3, fixed plate 3 keeps away from one side center of gas dispersion mouth 2 and installs trachea interface 4, still be equipped with trachea 5 in the hollow body that is located the first section, the one end and the gas dispersion mouth 2 of trachea 5 are connected, the other end passes fixed plate 3 and is connected with trachea interface 4, fixedly connected with is used for restricting the spacing fender ring 6 of hollow body roll-off in the tail end of the hollow body that is located the tail section of shell body 1, but the center of spacing fender ring 6 air supply pipe interface 4 stretches out shell body 1, hollow body tail end department that is located the tail section of shell body 1 installs rather than screw-thread fit's back lid.

When in use, the rear cover is opened, the outer shell 1 is erected, all hollow tube bodies are limited by the limiting baffle ring 6 and are positioned on the limiting baffle ring 6, meanwhile, the air tube connector 4 positioned at the tail end of the first section of the outer shell 1 extends out of the center of the limiting baffle ring 6 and is positioned outside the bottom end of the outer shell 1, then the ventilation hose 8 is connected with the air tube connector 4, the outer shell 1 is overturned after connection, so that the first section of the hollow tube body slides out of the top end of the outer shell 1, workers pull out and clamp the first section of the hollow tube body outwards after sliding out, and pull out each section of the hollow tube body behind in sequence, the telescopic tube structure of the outer shell 1 is the telescopic tube structure of the existing fishing rod, when the pulling-out length is suitable for the working height, the fishing rod stops, then supplies air through the air source 9, the air enters the air tube 5 of the outer shell 1 through the ventilation hose 8 and is then sprayed out from the air dispersing port 2, and at the moment, the air dispersing port 2 faces the air alarm device, enabling the sprayed gas to face the gas alarm device, and detecting whether the gas alarm device is in good condition or not by judging whether the gas alarm device alarms or not; after the detection is finished, only the air source 9 needs to be closed, each section of hollow pipe body needs to be withdrawn in sequence, the air pipe connector 4 is exposed out of the tail end of the outer shell body 1, the air pipe 5 is taken down, and then the rear cover is covered, so that the air pipe can be carried to the next detection position.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention should be covered within the protection scope of the present invention.
