The utility model discloses a leak protection nozzle, when letting in gas toward the trachea, even atmospheric pressure changes and makes the trachea take place to expand with the junction of nozzle body, its external diameter of trachea is close to the side looks butt of external diameter of trachea with first flange all the time to prevent that gaseous emergence from leaking, improved tracheal gas tightness and security.
Description
Technical Field
The utility model relates to a nozzle field, concretely relates to bayonet leak protection nozzle.
Background
At present, nozzles in the market are generally directly sleeved or embedded on an air pipe, as shown in fig. 1. When gas is introduced into the gas pipe, the joint of the gas pipe and the nozzle is expanded due to the change of the gas pressure, so that gas leakage is caused, and potential safety hazards are caused.
Therefore, how to design a nozzle for preventing gas leakage is a technical problem to be solved by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model provides an inserted leakage-proof nozzle.
The utility model discloses a solve the technical scheme that its problem adopted and be:
an insert leak-proof nozzle comprising a nozzle body, wherein:
the nozzle body is provided with a first flange and a second flange along the same direction, and an installation cavity is formed between the first flange and the second flange;
the air pipe is inserted into the installation cavity and is detachably connected with the nozzle body.
From this, when letting in gas to the trachea, even atmospheric pressure changes and makes the junction of trachea and nozzle body take place the inflation, its trachea external diameter is close to the side looks butt of trachea external diameter with first flange all the time to prevent that gas from taking place to leak, improved tracheal gas tightness and security.
Further, the first flange is higher than the second flange.
Further, the nozzle body is fixedly connected with the air pipe through a bolt.
Further, the first flange is fixedly connected with the air pipe through bolts.
Further, the first flange and the second flange are both annular flanges.
Further, the edge of the first flange, which is far away from the outer diameter of the air pipe, is provided with a first chamfer.
Further, the edge of the second flange close to the inner diameter of the air pipe is provided with a second chamfer.
To sum up, the utility model provides a pair of bayonet leak protection nozzle, after inserting the trachea installation intracavity, when letting in gas toward the trachea in, even atmospheric pressure changes the junction that makes trachea and nozzle body and takes place the inflation, its external diameter of trachea is close to the side looks butt of external diameter of trachea with first flange all the time to prevent that gas from taking place to leak, improved tracheal gas tightness and security.

Detailed Description
For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
As shown in fig. 1 to 3, the present invention provides an insertion type leakage prevention nozzle, which comprises a nozzle body 2, wherein the nozzle body 2 is cylindrical and the diameter thereof is gradually reduced along the axial direction thereof, thereby forming a horn-like shape. A first flange 21 and a second flange 22 are also provided in the same direction on the top of the nozzle body 2. In the present embodiment, the first flange 21 and the second flange 22 are both annular flanges, and the height of the first flange 21 is higher than that of the second flange 22. An installation cavity for inserting the air pipe 1 is formed between the first flange 21 and the second flange 22, and after the air pipe 1 is inserted into the installation cavity, the air pipe 1 is detachably connected with the nozzle body 2. In the present embodiment, the first flange 21 of the nozzle body 2 is connected to the air pipe 1 by bolts.
Therefore, when the air pipe 1 is inserted into the installation cavity and air is introduced into the air pipe 1, even if the air pressure is changed to expand the joint of the air pipe 1 and the nozzle body 2, the outer diameter of the air pipe 1 is always abutted against the side surface of the first flange 21 close to the outer diameter of the air pipe 1, so that air leakage is prevented, and the air tightness and the safety of the air pipe 1 are improved.
As shown in fig. 3, the edge of the first flange 21 away from the outer diameter of the air tube 1 is provided with a first chamfer 211; the first chamfer 211 can prevent the edge of the first flange 21 from rubbing against other objects after the trachea 1 is inflated; in addition, the edge of the second flange 22 close to the inner diameter of the trachea 1 is provided with a second chamfer 221; through setting up this second chamfer 221, when this trachea 1 inserted this installation intracavity, can slide in along the inclined plane on the second chamfer 221, make things convenient for the installation between trachea 1 and the nozzle body 2, improve the installation effectiveness.
The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
