Description

A kind of Minisize oxygen cylinder for medical purpose

Technical field

The utility model relates to a kind of oxygen cylinder, particularly a kind of Minisize oxygen cylinder for medical purpose.

Background technique

At present, known medical oxygen cylinder is stretched with integral material mostly, the steel jointless structure that is spun into, and promptly the ordinary oxygen gas cylinder with industrial is identical, this oxygen cylinder volume is big, heavy, inconvenience is carried again, though the aluminum alloy oxygen cylinder had appearred in recent years, and light not enough, annex is various, as cylinder valve, reduction valve etc., cost is also higher, a kind of not only light but also inexpensive novel oxygen cylinder of society need.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of promptly light, the miniature oxygen cylinder of the new medical that cost is cheap again.

Above-mentioned technical problem of the present utility model is by providing a kind of miniature oxygen cylinder of new medical with following structure to solve, this Minisize oxygen cylinder for medical purpose adopts the composite structure of metal and plastics, promptly utilized the characteristic of the intensity of metallic material, utilized the plastics cost low again, easily processing, the characteristics of light specific gravity, have complementary advantages, thereby guarantee the both light, inexpensive again of Minisize oxygen cylinder for medical purpose, it is convenient to use again.This Minisize oxygen cylinder for medical purpose is made up of bottle, enhancing housing, oxygen-adding valve (built-in safety valve), switch valve (built-in safety valve), dust cover, storage oxygen, two chambers of decompression that partition wall is arranged in the middle of bottle manufactures, following is storage oxygen chamber, the oxygen-adding valve that has safety valve is installed, for filling and store oxygen below it; Top is relief chamber, for making high pressure oxygen enter decompression; Upper and lower two chambers communicate two chambeies by the switch valve of partition wall with the smooth passage, the relief chamber loam cake is processed a through hole, the hole some is processed with screw thread, and it is relative and concentric with the smooth passage with the switch valve valve of bottle partition wall, switch valve is installed in it by screw thread and can be stored up the oxygen chamber by switch along with screw thread rotation, the top of switch valve is by the outlet nozzle that is threaded, for output oxygen; A switch bracket also is installed on relief chamber, dust cover also is installed on it; The enhancing housing is coated on the outside of bottle or serves as a contrast therein; But the outside is the suit protecting cover also, thereby has just realized the purpose of this utility model.

The beneficial effects of the utility model are: adopt cavity volume decompression principle, simple in structure integrated, the enhancing housing of outside bottle clad metal has realized that plastic-steel is integrated, i.e. weight reduction reduces cost again, has very strong practicability.
