Abstract
The utility model relates to a can connect external conduit connector of respirator, it includes respirator link and external conduit connection end, and they connect through the middle-end, the respirator link is minor diameter cavity external screw thread pipe, external conduit connection end is major diameter cavity external screw thread pipe or the plain end hollow tube of taking the recess. The utility model discloses connect the convenient, respirator of being convenient for to wear.
Description
Technical Field
The utility model relates to a conduit connector, concretely relates to external conduit connector of gas mask.
Background
The gas mask is matched with an external conduit, so that people with the mask, who work in a polluted environment, can breathe fresh air, and the gas mask is a good safety protection device. The gas mask is matched with an active carbon gas filter box at a gas suction port, is a very light safety protection material, but the matched active carbon gas filter box is small, so that the gas mask is not suitable for long-time operation in a toxic environment. The long-time operation in toxic environment can be realized by wearing the gas mask with an external catheter, but the wearing of the gas mask is troublesome, the work of wearing the gas mask for a long time is very difficult, suffocation feeling is generated, and operators are often unwilling to seriously wear the gas mask.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims at overcoming the defects in the prior art and providing the external conduit connector of the gas mask which is convenient to connect and wear.
The technical scheme is as follows: in order to solve the technical problem, an external conduit connector that can connect respirator, it includes respirator link and external conduit connection end, they connect through the middle-end, the respirator link is minor diameter cavity external screw thread pipe, external conduit connection end is major diameter cavity external screw thread pipe or takes the plain end hollow tube of recess.
The connecting end of the gas mask is a hollow tube with the outer diameter of 32 mm and the thread pitch of 3 mm.
When the external conduit connecting end adopts a large-diameter hollow external thread pipe, the external diameter is 42 mm, and the external thread pitch is 5 mm.
When the external conduit connecting end adopts a flat-mouth hollow tube with a groove, the outer end surface of the external conduit connecting end is a flat-mouth end, and the groove is formed in the outer wall of the tube body.
The middle end is a hexagonal nut end.
The connecting end of the gas mask, the middle end and the connecting end of the external connecting conduit are integrally formed.
The middle end is provided with a buckle opening.
The external conduit of the gas mask is a threaded interface with the outer diameter of 42 mm and the thread pitch of 5 mm, and the other end of the interface is bound with a special hose. The air suction port of the gas mask is an internal thread plastic connector, the inner diameter is 32 mm, the thread pitch of the internal thread is 3 mm, and the internal thread plastic connector cannot be directly matched and connected with an external conduit of the gas mask.
Has the advantages that: compared with the prior art, the utility model, it is showing the advantage and is: the utility model discloses overall structure sets up rationally, establishes being connected respirator's external pipe and respirator's induction port, and minor diameter cavity external screw thread pipe is connected with respirator, external pipe connection end and external pipe's special hose connection or with external pipe threaded connection, and the middle-end is the hexagon nut form, and the hand of being convenient for is screwed, and the operating personnel in general slight polluted environment can use the long-time normal light work of the supporting external pipe of respirator.
Drawings
FIG. 1 is a diagram showing the connection end of the respirator of the present invention connected to a large-diameter hollow external threaded tube;
FIG. 2 is a connection diagram of the connecting end of the respirator and the flat hollow tube with a groove of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in figure 1, a can connect external pipe connector of respirator, it includes respirator link 1 and external pipe link, they connect through intermediate end 2, respirator link 1 is minor diameter cavity external screw thread pipe, external pipe link is major diameter cavity external screw thread pipe 3, and its external diameter is 42 millimeters, and external screw pitch is 5 millimeters, respirator link 1 is external diameter 32 millimeters, the hollow tube of external screw pitch 3 millimeters, intermediate end 2 is the hexagon nut end be equipped with knot mouth 7 on the intermediate end 2, respirator link 1, intermediate end 2, external pipe link integrated into one piece.
As shown in figure 2, a can connect external pipe connector of respirator, it includes respirator link 1 and external pipe link, they connect through middle-end 2, respirator link 1 is minor diameter cavity external screw thread pipe, external pipe link is the plain end hollow tube of taking the recess, and its terminal surface 4 is the plain end, and recess 5 is established on 6 outer walls of body, respirator link 1 is external diameter 32 millimeters, the hollow tube of external screw pitch 3 millimeters, middle-end 2 is the hexagon nut end be equipped with knot mouth 7 on the middle-end 2, respirator link 1, middle-end 2, external pipe link integrated into one piece.
The utility model discloses overall structure sets up rationally, establishes being connected respirator's external pipe and respirator's induction port, and minor diameter cavity external screw thread pipe is connected with respirator, external pipe connection end and external pipe's special hose connection or with external pipe threaded connection, and the middle-end is the hexagon nut form, and the hand of being convenient for is screwed, and the operating personnel in general slight polluted environment can use the long-time normal light work of the supporting external pipe of respirator.
The utility model provides a thinking and method, the method and the way of specifically realizing this technical scheme are many, above only the utility model discloses a preferred embodiment should point out, to the ordinary technical personnel in this technical field, not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements and moist decorations, these improvements should also be regarded as the utility model discloses a protection range, each component that does not make clear and definite in this embodiment all can be realized with prior art.
