Abstract

The utility model relates to a coupling for mouth of oxygen cylinder, which belongs to the spiral clamping mechanism. The coupling for mouth of oxygen cylinder comprises a coupling head whose centre has a hole, and a threaded rod connected with a briquetting; the coupling head and the threaded rod are arranged in a rectangular frame; the coupling head can be extended into the air outlet hole of an oxygen cylinder; the briquetting can press the main body of the mouth of oxygen cylinder by rotating the threaded rod; the coupling head is pressed tightly with the air outlet hole of the oxygen cylinder at the same time; the coupling for mouth of oxygen cylinder can supply gas outward by opening the oxygen cylinder. The utility model replaces the screw thread connection of the existing mouth of oxygen cylinder and a pressure reducer, and can prolong the service life of the mouth of oxygen cylinder. The utility model has the advantages of low cost, easy use and safety.

Description

Joiner for mouth of oxygen cylinder

The utility model is a kind of oxygen bottle neck joiner, is and the matching used spiral fastening device of oxygen bottle neck.

Existing oxygen bottle neck connects with decompressor, be to connect with the outside thread of oxygen bottle neck air outlet hole by the coupling nut on the decompressor, coupling head on the decompressor and oxygen bottle neck air outlet hole are compressed, with realize oxygen cylinder through decompressor to user's oxygen supply, coupling head on the decompressor, coupling nut and whole oxygen bottle neck are all by copper alloy made, because the repeatedly collision in installing/dismounting and the handling process, the outside thread of oxygen bottle neck air outlet hole often is damaged, also just caused the damage of coupling nut on the decompressor, just may leak air, slide fastener collapses the accident of taking off.Because of oxygen bottle neck air outlet hole outside thread can not be repaired after being damaged, then the oxygen bottle neck and the coupling nut that just must more renew, thus increased the consumption of non-ferrous metal and fund.

The purpose of this utility model is a kind of joiner of design, connects the scyewed joint that replaces oxygen bottle neck air outlet hole and decompressor with compressing, and to reach the working life that prolongs the oxygen bottle neck, improves safety coefficient, and switch is purpose easily.

The technical solution of the utility model is: coupling head is stretched in the air outlet hole of oxygen cylinder, the briquetting that drives with a rotary screw withstands the oxygen nozzle body, and coupling head and screw are in a framework, during rotary screw, the air outlet hole of coupling head and oxygen bottle neck just compresses, and oxygen cylinder is outside air feed just.

Specifically, the utility model is achieved in that to have a rectangular framework 1, on the top and bottom on the long limit of framework two slideways 2 are arranged respectively, the porose coupling head in center 3 is housed in hole, framework front end garden, in the screw of the rear end of framework, screw rod 4 is housed, one briquetting that is connected with screw rod 5 is arranged in the middle of the framework, the head of screw rod is a top 6 less than footpath at the bottom of the screw rod, between top and screw flight part, an annular control flume 7 is arranged, the one half garden shape groove 8 that can hold oxygen bottle neck safety valve is arranged below the briquetting first half, the latter half of upper and lower surface of briquetting respectively has two inner bolt holes 9, there is a rectangular groove 10 at the inner bolt hole rear, one blind hole 11 of intersecting with saturating groove is arranged on the ear end face of briquetting, two control strips 12 are housed in the saturating groove of briquetting, have two can move with screw 13 along the framework slideway and be fixed on two pressing plates 14 on the briquetting at the briquetting upper and lower surface.After screw head inserted the blind hole of briquetting, two control strips were stuck on the annular control flume of screw rod from upper and lower surface, and the outside is blocked by pressing plate, and screw rod and briquetting are linked together like this, and rotary screw, briquetting can move forward and backward, but can not rotate.

For easy to use, the screw rod tail of joiner can be made square, hexagon or have the garden shape of handle.

The coupling head of joiner can match with decompressor, also can make the different size shape according to user's different needs, directly matches with high-strength pipe.The coupling head of joiner can be by copper alloy made, and other parts all can be made of steel material, and cost is low, low price.

Accompanying drawing 1 is that oxygen cylinder is chewed the joiner structure schematic representation.

Among the figure, 1-framework, 2-slideway, the 3-coupling head, 4-screw rod, 5-briquetting, the 6-top, 7-annular control flume, 8-half garden shape groove, the 9-inner bolt hole, the saturating groove of 10-, 11-blind hole, the 12-control strip, the 13-screw, the 14-pressing plate uses the utility model, the outside thread that does not re-use existing oxygen bottle neck air outlet hole connects with the nut of decompressor, has obviously prolonged the working life of oxygen bottle neck, and, safety more convenient than existing connection and switch.

Certain hospital is indoor to the ward concentrated oxygen supply, rotating many upright oxygen cylinders, the oxygen bottle neck connects with the high strength oxygen hose that leads to the ward, after trial edition model utility one oxygen bottle neck joiner connects, do not re-use the outside thread of oxygen cylinder mouth, thereby prolonged working life of oxygen bottle neck, and safety how.Operator stand in the outside of oxygen cylinder, but switch oxygen cylinder just easy to operately when using scyewed joint has been howed.To the oxygen cylinder of often moving at the factory scene, loading and unloading, frequently use, it is better to use effect of the present utility model.

Claims

A kind of oxygen bottle neck joiner, it is characterized in that this joiner has: rectangular framework 1, the long limit of framework has slideway 2 on the top and bottom, be contained in the porose coupling head 3 in center in the hole, framework front end garden, be contained in the screw rod 4 in the back-end framework screw thread, with the joining briquetting 5 of screw rod, the head of screw rod is a top 6 less than footpath at the bottom of the screw rod, between top and screw flight part, an annular control flume 7 is arranged, the one half garden shape groove 8 that can hold oxygen bottle neck safety valve is arranged below the briquetting first half, briquetting is latter half of respectively two inner bolt holes 9 up and down, there is a rectangular groove 10 at the inner bolt hole rear, one blind hole 11 of intersecting with saturating groove is arranged on the ear end face of briquetting, two control strips 12 are housed in the saturating groove of briquetting, be fixed on the briquetting upper and lower surfaces two pressing plates 14 that can move along the framework slideway with screw 13.
