Description

A kind of fire extinguisher bottle

[technical field]

The utility model belongs to fire extinguisher device field, the fire extinguisher bottle that uses on especially a kind of portable fire extinguisher.

[background technology]

In existing fire extinguisher, what use is the bottle that carbon steel is made, the structure of above-mentioned this bottle is that bottleneck portion is threaded, and the actuation means by this fire extinguisher that is threaded, bottle is generally two parts and forms, comprise bottle shell and bottom end cover, link into an integrated entity by welding or other mode between bottle shell and the bottom end cover.Adopt the bottle of this structure, be very easy to occur the phenomenon of bottle oxide etch at first in use, appear at the weld bond part after the welding especially easily, in use be very easy to go wrong, in addition because the defective in the welding process, produce between above-mentioned bottle and the bottom end cover in causing using and leak, cause fire extinguisher to lose efficacy.Because above-mentioned bottle adopts carbon steel material to make bottle, in particular cases produce explosion time in addition, broken easily fragment, serious threat user's the safety of producing.The existence of the problems referred to above has a strong impact on the useful life of fire extinguisher simultaneously.Above-mentioned in a word problem does not also have solution preferably so far.

[summary of the invention]

In order to solve the above problems, the purpose of this utility model provides a kind ofly can be had than the long life, and produces the dangerous smaller a kind of fire extinguisher bottle of explosion time under special circumstances.

For realizing above purpose, the technical solution that the utility model adopts does not comprise following technology contents: a kind of fire extinguisher bottle, comprise the screwed bottle of bottleneck, the bottom end cover of described bottle is fixed on the bottle for modes such as welding, the bottom end cover and the bottle of described bottle are structure as a whole, and be formed with the disappointing structure that prevents the bottle blast on this bottle side, described disappointing structure is that the bottle middle part forms the thin bottle wall of one section other part of relative bottle.

Described bottle adopts reasonable metallic copper of ductility or aluminium to make.The bottom of described bottle is the sphere shape of indent, and the thickness at the described bottle end is greater than the average thickness of body.

The utility model is by adopting above-mentioned technical solution, obtained following positive technique effect and advantage: at first by adopting bottle and the integrally formed structure of bottom end cover, make the joint of above-mentioned fire extinguisher bottle bottle and bottom end cover have relative structure uniformly, having avoided appearing at some weak parts produces damaged, and the situation that causes whole fire extinguisher to be scrapped has prolonged service life of fire extinguisher; By one section structure of thin part is set on the sidewall at bottle middle part, to in particular cases produce explosion time, guarantee that bottle is at first begun by this part, simultaneously owing to adopted the reasonable metals of ductility such as copper or aluminium, therefore in case producing explosion time, bottle only can ftracture, and can not produce fragment, has guaranteed user's safety preferably.

[description of drawings]

Fig. 1 is a profile schematic diagram of the present utility model;

Fig. 2 is a cutaway view of the present utility model.

[specific embodiment]

Below in conjunction with accompanying drawing the utility model is further described:

As depicted in figs. 1 and 2, its profile is identical in common fire extinguisher profile as can be seen in Fig. 1.A kind of fire extinguisher bottle of the present utility model as can be seen in Fig. 2, comprise that bottleneck 1 is threaded 2 bottle, screw thread 2 is in processing behind the global formation, the described bottle 3 and the bottle end 4, are structure as a whole, this structure is by carrying out punching press and drawing process global formation to aluminium sheet, so on these bottle 3 sides, be formed with the disappointing structure that prevents bottle 3 blasts, described disappointing structure is that bottle 3 middle parts form the thin bottle wall 5 of one section other part of relative bottle, and the bottle wall 5 that this section is relatively thin is to form by above-mentioned drawing process.Bottle 3 preferably adopts reasonable metallic copper of ductility or aluminium etc. to make, to satisfy the processing request of above-mentioned bottle.The bottom of described bottle 3 is the sphere shape of indent, and the thickness at the described bottle end 4 is greater than the average thickness of body, by at the bottom of the sphere shape bottle of this indent 4 and structure 4 can bear bigger pressure at the bottom of can making bottle, guarantee the bottle working strength at the end 4.By adopting above-mentioned structure at bottle 3 explosion time under special circumstances, split by thin bottle wall 5 places, gases at high pressure are wherein released, play preventing that the fragment that whole bottle blast is produced from hurting sb.'s feelings.

Claims

1, a kind of fire extinguisher bottle, comprise the screwed bottle of bottleneck, the bottom end cover of described bottle is fixed on the bottle, it is characterized in that: the bottom end cover and the bottle of described bottle are structure as a whole, and be formed with the disappointing structure that prevents the bottle blast on this bottle side, described disappointing structure is that the bottle middle part forms the thin bottle wall of one section other part of relative bottle.

2, a kind of fire extinguisher bottle according to claim 1 is characterized in that: described bottle adopts reasonable metallic copper of ductility or aluminium to make.

3, a kind of fire extinguisher bottle according to claim 1 is characterized in that: the bottom of described bottle is the sphere shape of indent, and the thickness at the described bottle end is greater than the average thickness of body.
