Description

Portable water-based fire extinguisher

Technical Field

The utility model relates to a fire extinguisher technical field, concretely relates to portable water base type fire extinguisher.

Background

The water-based fire extinguisher is suitable for extinguishing fire at the beginning of inflammable solid or non-water-soluble liquid, can extinguish fire of live equipment, and is widely applied to places such as oil fields, oil depots, ships, factories, shops and the like.

However, the liquid feeding pipes of the existing portable water-based fire extinguisher are hoses, when fire is extinguished, the liquid feeding pipes need to be held by one hand to be close to the position of the nozzle for extinguishing the fire, if the fire is strong, the fire is easy to burn, and the use safety is not high.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide a high-safety portable water-based fire extinguisher.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a portable water-based fire extinguisher is characterized in that: the bottle comprises a bottle body, a pressing valve and a liquid sending pipe which are arranged at the upper end of the bottle body, a nozzle arranged at the free end of the liquid sending pipe and a holding pipe sleeved outside the liquid sending pipe, wherein the holding pipe comprises a plurality of sub pipes which are sequentially sleeved, and the sub pipe with the smallest diameter is fixedly connected with the nozzle; in two adjacent sub-pipes, a through hole is formed in the pipe wall of the sub-pipe with the smaller diameter, which is far away from one end of the nozzle, an elastic sheet is arranged on the inner wall of the sub-pipe with the smaller diameter, a limiting bead which can extend out of the through hole is arranged at the free end of the elastic sheet, and a limiting hole into which the limiting bead on the sub-pipe with the smaller diameter can extend is arranged at one end, which is close to the nozzle, of the sub-pipe with the larger; in two adjacent sub-pipes, the inner wall of the sub-pipe with the larger diameter is provided with a guide groove along the length direction, wherein the guide groove can be used for the limiting bead to slide in the sub-pipe, and the guide groove on the same sub-pipe is connected with the limiting hole.

Furthermore, the outer wall of the sub-pipe sleeved on the outermost side in the holding pipe is provided with anti-skid grains.

Further, the holding tube is made of stainless steel material.

Furthermore, a sub-pipe with the smallest diameter in the holding pipe is fixedly connected with the nozzle through threads.

Compared with the prior art, the utility model has the advantages of it is following: the holding pipe is formed by sleeving the sub-pipes, when the fire is less, the holding pipe is directly held on the holding pipe, the holding pipe is more convenient than a hand-held liquid delivery pipe and the nozzle is more convenient to align with a fire source, and when the fire is more fire, the outermost sub-pipe is pulled towards the direction far away from the nozzle, so that the length of the holding pipe can be lengthened, the hands of fire extinguishers are far away from flames, and the safety of the fire extinguishers is ensured; through setting up anti-skidding line, the personnel of being convenient for put out a fire grip, have better operability.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

In the description of the present invention, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the terms of orientation and positional relationship indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of protection of the present invention.

Fig. 1 to 3 are schematic structural views of the fire extinguisher according to the present application, and as shown in the drawings, the portable water-based fire extinguisher includes a bottle body 1, a pressing valve 2 and a liquid sending tube 3 which are arranged at the upper end of the bottle body 1, a nozzle 4 which is arranged at the free end of the liquid sending tube 3, and a holding tube 5 which is sleeved outside the liquid sending tube 3, wherein the holding tube 5 includes a plurality of sub-tubes 51 which are sequentially sleeved, and the sub-tube 51 with the smallest diameter is fixedly connected with the nozzle 4; in two adjacent sub-tubes 51, a through hole 52 is formed in the tube wall of one end, away from the nozzle 4, of the sub-tube 51 with the smaller diameter, an elastic sheet 53 is arranged on the inner wall of the sub-tube with the smaller diameter, a limiting bead 54 capable of extending out of the through hole 52 is arranged at the free end of the elastic sheet 53, and a limiting hole 55 capable of allowing the limiting bead 54 on the sub-tube 51 with the smaller diameter to extend into is arranged at one end, close to the nozzle 4, of the sub-tube 51 with the larger diameter; in two adjacent sub-tubes 51, the inner wall of the sub-tube 51 with a larger diameter is provided with a guide groove 56 along the length direction, in which the limiting bead 54 can slide, and the guide groove 56 on the same sub-tube 51 is connected with the limiting hole 55, in order to reduce the shaking, in the embodiment, the number of the limiting beads 54 of each sub-tube 51 is at least three, and the number of the corresponding limiting holes 55 is also three.
