Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: an elbow joint comprises a pipe body 1, wherein one end of the pipe body 1 is provided with an inclined pipe 11, and an included angle between the pipe body 1 and the inclined pipe 11 is 30-50 degrees; because the contained angle between body 1 and the pipe chute 11 is the acute angle for consequently make this joint can be suitable for in trachea and tracheal corner, solve the problem that current quarter bend exists.

The inside of body 1 still is equipped with first cavity 10, through the pressure cap 2 that is equipped with the one end of body 1 is connected to the tight hoop 7, jump ring 6 and the first sealing washer 5 that will be equipped with are fixed in first cavity 10.

After compressed air in the air pipe enters the pipeline 1, the tightening sleeve 7 can be driven to move outwards, and the larger the air pressure is, the larger the pressure for clamping the air pipe by the tightening sleeve 7 is due to the limitation of the first cavity 10, so that the air pipe can be fixed on the pipeline.

Further, the cross section of the clamp spring 6 is S-shaped, and the cross section of the clamp spring 6 is S-shaped, namely, after the clamp spring 6 is cut, the thickness surface of a plate material of the clamp spring 6 is S-shaped; therefore, when the clamp spring 6 moves outwards, the downward bent part abuts against the end face in the first cavity 10, so that the movement of the clamp spring 6 is limited, and the clamp spring 6 is upwards tightened towards one surface of the pipe body 1 after the downward bent part is stressed, so that the clamping of the air pipe and the fixation of the air pipe are realized.

Furthermore, since the end of the inclined tube 11 away from the tube body 1 is further provided with the connecting part 3, the tube body 1 can be fixed on an air pipe or a gas appliance by using the connecting part 3; particularly, the included angle between the inclined tube 11 and the tube body 1 is an acute angle, so that the gap between the outer surfaces of the air-pipe air-using equipment can be reduced, and the arrangement of the air pipes is optimized; wherein, the included angle between the inclined tube 11 and the tube body 1 is preferably 45 degrees.

On the basis of the scheme, the inclined tube 11 is further provided with the limiting protrusion 12, and the second sealing ring 4 is further arranged between the connecting part 3 and the limiting protrusion 12, so that the connecting part of the connecting part 3 and the inclined tube 11 is sealed, air source leakage is avoided, meanwhile, the inclined tube 11 cannot be driven to rotate when the connecting part 3 rotates, and the tube body 1 and the air tube cannot rotate along with the rotation; wherein, the outer wall surface of the connecting part 3 is connected with the gas-using equipment through external threads, and the gas-using equipment can be a cylinder and the like.

Further, because the inclined tube 11 and the inside of body 1 junction still are equipped with second cavity 13, consequently, after the trachea got into body 1, tracheal tip can bulge in the left side of sealing plug 5, and the inside length that the extension trachea got into body 1 further promotes the stability behind trachea and body 1 connected.

The utility model discloses a theory of operation is: inserting the air pipe with the corresponding size from the end of the pressing cap 2 through the clamp spring 7 and the first sealing ring 5 until the air pipe is abutted against the end face of the second cavity 10; after compressed air is introduced, the air pipe can move outwards from one strand, namely, the pushing force moves towards the direction of the pressing cap 2, and the air pipe is clamped in the clamp spring 7;

when outward thrust exists, the air pipe and the clamp spring 7 move outwards together, and the clamp spring 7 is S-shaped, and is clamped more tightly when pushed outwards until the two forces are balanced, so that the fixation and clamping of the air pipe can be realized;

when the air pipe is to be pulled out, compressed air is released firstly, the pressing cap 2 and the clamp spring 7 are pressed down forcefully to be unfolded, and then the air pipe can be pulled out easily.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
