Abstract
The utility model relates to a multipurpose connector for respirators, which comprises a connector body, an intake connecting tube and an outtake connecting tube connected with a respiratory air box of a respirator. The multipurpose connector is characterized in that: the multipurpose connector also comprises an auxiliary connecting tube and a gate valve, one of the intake connecting tube and the auxiliary connecting tube is not provided with the gate valve, and the other of the intake connecting tube and the auxiliary connecting tube is provided with the gate valve. The utility model solves the problem that the prior art cannot conveniently supply air source to a third party and cannot be connected with the air source of the third party.
Description
Technical field
The utility model relates to a kind of breathing mask multipurpose joint, and it belongs to respirator class articles for use accessory class.
Background technology
Breathing mask mainly is applicable to fields such as fire-fighting, the mine disaster relief, chemical industry, boats and ships, warehouse, laboratory, waterworks, oil gas field.In fire, toxic and harmful and adverse circumstances such as suffocate, the staff wears this respirator can self-help escape, carry out work such as accident treatment and industrial operation.Existing breathing mask in use, the tidal air box on the general breathing mask connects with flexible pipe through a straight-through joint, said flexible pipe is communicated to gas cylinder again, by gas cylinder to the breathing mask air feed.Aforesaid joint is made up of main body, air inlet connecting tube and the connecting tube of giving vent to anger mostly; The problem that exists in the prior art is to provide one to one by such joint, and equity is communicated with, yet in practical application, such as in mine rescue; The mine depths takes place to arrive at present in mine disaster in the rescue personnel of mine rescue crew; Found the mine disaster personnel, the personnel that in mine, work are furnished with emergent breathing mask mostly, but after the mine disaster generation; As time goes on; When the rescue personnel finds the mine disaster personnel, on many situation the mine disaster personnel with the gas cylinder of breathing equipment in the gas that can supply breathe all can not be provided, at this moment the demand of changeing air feed to mine disaster personnel's breathing mask is just arranged from the entrained gas cylinder of rescue personnel.Obviously the joint of prior art can not satisfy these needs.In addition; Mine rescue in reality is on-the-spot; The tolerance consumption that also usually takes place in the entrained gas cylinder of draegerman is over; At this moment the gas cylinder that need utilize non-draegerman to be equipped with also often takes place because draegerman's joint does not match and out of use situation with the on-the-spot gas cylinder joint that can provide.The above proves absolutely that the joint of prior art has further improved needs.
Summary of the invention
The purpose of the utility model is to provide a kind of breathing mask multipurpose joint, to overcome the problem that prior art exists.
A kind of breathing mask multipurpose joint of the utility model; Comprise adapter body, air inlet connecting tube, the connecting tube of giving vent to anger that connects with breathing mask tidal air box; It is characterized in that at least also comprising an auxiliary connecting tube; Also comprise gate valve simultaneously, in described air inlet connecting tube and auxiliary connecting tube, have one gate valve is not set, be provided with gate valve in remaining air inlet connecting tube and the auxiliary connecting tube.
This breathing mask multipurpose joint of the utility model owing to introduced auxiliary connecting tube, provides source of the gas or inserts third party's source of the gas to the third party so it can open gate valve when needed easily.The effect of gate valve be provide when not required close its place connecting tube maybe.
As further improvement, have at least the joint categories of joint categories and air inlet connecting tube of an auxiliary connecting tube different, setting can provide the different possibilities that connect with cylinder interface with air inlet connecting tube joint categories like this.
Description of drawings
Fig. 1 is a kind of breathing mask multipurpose joint structural representation that the utility model preferred embodiment provides.
Among the figure, 1 for adapter body, 2 for the air inlet connecting tube, 3 for the connecting tube of giving vent to anger, 4 for auxiliary connecting tube, 5 be gate valve.
The specific embodiment
A kind of breathing mask multipurpose joint and the accompanying drawing thereof that below will combine the utility model preferred embodiment to provide are described further the utility model.
A kind of breathing mask multipurpose joint that the utility model preferred embodiment provides; Shown in accompanying drawing 1, comprise adapter body 1, air inlet connecting tube 2, the connecting tube 3 of giving vent to anger that connects with breathing mask tidal air box, in this preferred embodiment; Also comprise an auxiliary connecting tube 4; In this preferred embodiment, the joint categories of give vent to anger connecting tube 3 and auxiliary connecting tube 4 is the pagoda type joint, and the joint categories of said air inlet connecting tube 2 is standard snap joint.
In this preferred embodiment, also comprise gate valve 5, said gate valve 5 is arranged in the auxiliary connecting tube 4.
In sum; A kind of breathing mask multipurpose joint of the utility model; Comprise adapter body, air inlet connecting tube, the connecting tube of giving vent to anger that connects with breathing mask tidal air box; It is characterized in that at least also comprising an auxiliary connecting tube, also comprise gate valve simultaneously, in described air inlet connecting tube and auxiliary connecting tube, have one gate valve is not set; Be provided with gate valve in remaining air inlet connecting tube and the auxiliary connecting tube, the problem that the utility model has solved that prior art exists can not be easily provides source of the gas and insert source of the gas from the third party to the third party.
The above is merely the specific embodiment of the utility model.But the utility model protection domain is not limited thereto.Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement; All should be encompassed within the protection domain of the utility model, therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
Claims (2)
