Abstract

The utility model relates to a protecting mask with a rotary separation type pipe, belonging to the labor protection supplies. The protecting mask with a rotary separation type pipe is suitable for being used for avoiding the human body being hurt in the places having high dust, toxic gas and other harmful substances. The protecting mask with a rotary separation type pipe contains a long pipe, a short pipe, a toxic gas mask, a slipknot cover, a pneumatic joint, a joint, a bearing and a pipe sleeve. The big end of the pipe sleeve whose small end is covered with the long pipe is fixed on the outer diameter of the bearing, and the inner bore of the bearing is fixed with the big end of the joint; the small end of the joint is connected with the lock end of the pneumatic joint whose the other end is fixedly connected with the short pipe in the anastomotic way; the other end of the short pipe is provided with a slipknot cover which is caused to be fixed with a slipknot seat on the toxic gas mask in the anastomotic way. The protecting mask with a rotary separation type pipe has simple structure, low cost, convenient operation and good effect.

Description

Band rotates the mask mouth mask of separate type pipe

One, technical field:

The utility model relates to a kind of mask mouth mask with rotation separate type pipe, belongs to articles for labour protection, and it is suitable for having high dust, poison gas and other harmful substance place, uses when avoiding human body to come to harm.

Two, background technology:

Existing protective mask has two types; a kind of is filtering type; it can not enter in the human respiratory tract toxic and harmful or dust by multiple filtration, the protection health; but; because it is a multiple filtration, so respiratory resistance is big, causes expiratory dyspnea; and to change filtering material, use cost height on schedule.Another kind is the protective mask of oxygen therapy formula, makes the human body oxygen intake, avoid toxic gas is sucked respiratory tract, but this protective mask need add band oxygen, so the cost height, and use inconvenient.So far, never there is band to rotate the mask mouth mask of separate type pipe,, uses when avoiding human body to come to harm for having high dust, poison gas and other harmful substance place.

The purpose of this utility model is to overcome expiratory dyspnea, use cost high and the cost height of oxygen therapy formula protective mask and the weak point of use inconvenience of existing filtering type protective mask, thereby provide a kind of with the mask mouth mask that rotates the separate type pipe, it is to adopt flexible rotation separator, connect pipe quickly and easily, the fresh air in uncontamination district is introduced the contaminated area, usefulness for people's breathing, thereby avoid the injury of the toxic and harmful of contaminated area and dust to human body, its manufacturing and use cost are low, easy to use, effective.

Three, summary of the invention:

The purpose of this utility model realizes by following approach:

The utility model includes long tube, short tube, breathing mask, slip-knot lid, pneumatic joint, joint, bearing, several parts of pipe box, the big end that small end is with the pipe box of long tube is fixed on the bearing outside diameter, and the endoporus of bearing and the big end of joint fixed, the fore shaft end that again small end of joint and the other end is fixedly connected with the pneumatic joint of short tube coincide and is connected, again the other end of short tube establish one with breathing mask on the slip-knot lid that coincide of slip-knot seat, and be fixed on the slip-knot seat.The end, be provided with packing ring in said slip-knot lid, helps sealing.Veneer mouth at said breathing mask is provided with outward extending flexible glue along interior week, so that make flexible glue be close to face when air-breathing, prevents that effectively dusty gas from sucking respiratory tract.

The utility model contrast prior art has following advantage:

1, the utility model is simple in structure, and manufacturing and use cost are low;

2, the utility model has the rotation separator, therefore use easily, and also effective.

Four, description of drawings:

Fig. 1 is the structural representation of the utility model embodiment, wherein:

The 1-long tube, 2-short tube, 3-breathing mask, 4-slip-knot lid, 5-pneumatic joint, 6-joint, 7-bearing, 8-trip bolt, 9-pipe box, 10-air admission hole, 11-slip-knot seat, 12-packing ring, 13-steam vent, 14-restraint zone, 15-flexible glue, 21-fore shaft end, 22-veneer mouth.

Fig. 2 is the structural representation of the utility model embodiment pipe box, wherein:

The big end of 16-, the 17-small end.

Fig. 3 is the structural representation of the utility model embodiment joint, wherein:

The 18-screw, the big end of 19-, 20-small end.

Five, the specific embodiment:

The utility model carries out height below in conjunction with accompanying drawing embodiment and describes in detail:

The utility model embodiment includes long tube 1, short tube 2, breathing mask 3, slip-knot lid 4, pneumatic joint 5, joint 6, bearing 7, pipe box more than 9 parts, its middle (center) bearing 7, pneumatic joint 5 grades and breathing mask 3 are to buy existing product from market, the big end 16 that small end 17 is with the pipe box 9 of long tube 1 is fixed on bearing 7 external diameters, and after the big end 19 of joint 6 passed the endoporus of bearing 7, be fixed in the screw 18 set on the big end 19 with trip bolt 8, the joint 6 and the endoporus of bearing 7 are fixed, the fore shaft end 21 that again small end 20 of joint 6 and the other end is fixedly connected with the pneumatic joint 5 of short tube 2 coincide and is connected, again the other end of short tube 2 establish one with mask 3 on the slip-knot lid 4 that coincide of slip-knot seat 11, and be fixed on the slip-knot seat 11.The end, be provided with packing ring 12, favourable sealing in said slip-knot lid 4.Along being provided with outward extending flexible glue 15 interior week,, prevent that effectively dusty gas from sucking respiratory tract at the veneer mouth 22 of said breathing mask 3 so that make flexible glue 15 be adjacent to face when air-breathing.

During use, restraint zone on the breathing mask 3 14 is fastened on the head, make breathing mask 3 be adjacent to mouth, nose, 20 identical connections of small end of fore shaft end 21 with the joint 6 of the pneumatic joint 5 between waist will be tied, the other end of long tube 1 is placed the uncontamination district, like this, when people breathe, because the effect of the outlet valve in the breathing mask 3, the fresh air in uncontamination district enters respiratory tract by long tube 1 through air admission hole 10 when air-breathing; During expiration, gas is discharged by steam vent 13 in the body.
