The utility model discloses a spacing portion of hard tube outer wall restricts the degree of depth that the hard tube inserted the hose, guarantees the state uniformity of car warm braw water route system pipeline assembly, and the whole car installation of being convenient for, through the degree of depth that spacing portion control hard tube inserted the hose, avoids reducing the hose and inserts not in place, leads to the risk that drops or leak with the hard tube.

Description

Soft and hard tube connection limit structure of car warm braw pipeline

Technical Field

The utility model relates to an automobile air conditioner, especially a car warm braw pipeline soft or hard tube connection limit structure.

Background

The connection mode of the hose and the hard pipe in the current automobile warm air waterway system pipeline assembly is that a raised boss is arranged on the hard pipe and inserted into the hose, the boss plays a role in sealing, and then the hose is connected by a clamp.

The soft and hard pipe connecting structure has the following problems: 1: the depth of the hose is deep or shallow, so that the states of the warm air pipelines are inconsistent, and the hose is difficult to connect and install on an automobile; 2: the hose is inserted the degree of depth and is too shallow, leads to the installation clamp not in place, fails to play fixed seal effect, leads to hose and hard tube to drop or sealed the leakage.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a car warm braw pipeline soft or hard union coupling limit structure to guarantee the product state uniformity, the installation of being convenient for, and reduce the hard tube and drop or leak the risk with the hose.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a car warm braw pipeline soft or hard union coupling limit structure, includes hard tube, hose, and hard tube one end is equipped with the boss, and this boss inserts in the mouth of pipe of hose one end, its characterized in that: the outer wall of the hard pipe is provided with a limiting part at a position close to the boss for limiting the depth of the boss of the hard pipe inserted into the pipe orifice of the hose.

Furthermore, the limiting part is an expanding section.

Further, the outer diameter of the flaring section is gradually increased along the insertion direction of the boss of the hard tube.

Furthermore, the limiting part is a radial annular bulge.

Furthermore, the outer contour of the radial annular bulge is a circular arc surface.

Furthermore, the limiting part is a marking line.

Further, the spacing part is 30mm away from the boss of the hard tube.

Furthermore, the outer diameter of the boss is large in the middle and small on two sides.

Has the advantages that: the utility model discloses a spacing portion of hard tube outer wall restricts the degree of depth that the hard tube inserted the hose, guarantees the state uniformity of car warm braw water route system pipeline assembly, and the whole car installation of being convenient for, through the degree of depth that spacing portion control hard tube inserted the hose, avoids reducing the hose and inserts not in place, leads to the risk that drops or leak with the hard tube.

The specific implementation mode is as follows:

the present invention will be further explained with reference to the accompanying drawings.

Example one

As shown in fig. 1 to 3, the utility model discloses a car warm braw pipeline soft or hard union coupling limit structure, including hard tube 1,

hose

4, 1 one end of hard tube is equipped with boss 2, and in this boss 2 inserted the mouth of pipe 5 of hose 4 one end, 1 outer wall of hard tube was close to 2 positions of boss and is equipped with spacing portion 3 for the degree of depth in the boss 2 of restriction hard tube 1 inserted the mouth of pipe 5 of hose 4.

In this embodiment, the limiting portion 3 is an expanding section. The outer diameter of the flaring section is gradually increased along the insertion direction of the boss 2 of the hard tube 1. The flaring section passes through equipment mould shaping, and spacing portion 3 is decided according to boss 2 insertion mouth of pipe 5 degree of depth with 2 distances of boss of hard tube 1, and in this embodiment, the flaring section is 30mm apart from the boss of hard tube 1, and boss 2 inserts the 5 in-process in the mouth of pipe, inserts the 5 degree of depth of mouth of pipe through this flaring section control boss 2.

In order to facilitate the smooth insertion of the boss 2 into the pipe orifice 5, the boss 2 adopts a reducing structure, and in the embodiment, the middle of the outer diameter of the boss 2 is large, and the two sides are small.

Example two

As shown in fig. 4 and 5, the difference between the first embodiment and the second embodiment is that the limiting portion 3 is a radial annular protrusion, and the outer profile of the radial annular protrusion is a circular arc surface. Radial annular is protruding to pass through equipment mould shaping, and spacing portion 3 is decided according to boss 2 inserting mouth of pipe 5 degree of depth with 2 distances of boss of hard tube 1, and in this embodiment, radial annular is protruding apart from the boss 30mm of hard tube 1, and boss 2 inserts mouth of pipe 5 in-process, inserts the mouth of pipe 5 degree of depth through this radial annular protruding control boss 2.

EXAMPLE III

As shown in fig. 6 and 7, the present embodiment is different from the first embodiment in that the limiting portion is a marking line, and the marking line is cured on the outer wall surface of the hard tube 1 in a coating manner. Spacing portion 3 is decided according to the boss 2 degree of depth that boss 2 inserted the mouth of pipe 5 with the boss 2 distance of hard tube 1, and in this embodiment, the marking line is 30mm apart from the boss of hard tube 1, and boss 2 inserts the 5 in-process of mouth of pipe, inserts the 5 degree of depth of mouth of pipe of boss 2 through this marking line control.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
