Description

Double-sealing joint for automobile air conditioner

Technical Field

The utility model relates to a vehicle air conditioner connects technical field, specific vehicle air conditioner double containment connects that says so.

Background

The traditional automobile air conditioner joint is mostly a single sealing joint, and if the operation is improper in the installation process or after the automobile air conditioner joint is used for a long time, the phenomenon of air leakage easily occurs in a single sealing ring damaged pipeline. For the pipeline joint for cooling the engine, the leakage-proof requirement is higher, and the single sealed joint cannot meet the design requirement. Therefore, the double-sealing joint for the automobile air conditioner is designed, and the problems are well solved.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned weak point that exists among the prior art, the utility model aims at providing an automobile air conditioner double containment connects.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a vehicle air conditioner double containment connects, includes straight tube A, straight tube B, sleeve pipe, connects A, connects B, connects C, seal groove A and seal groove B, straight tube A sets up in the sleeve pipe right part, straight tube B sets up in the sleeve pipe left part, straight tube A top is provided with connects A, straight tube B top is provided with connects B, straight tube B bottom is provided with connects C, seal groove A, seal groove B set up in sleeve pipe upper right part, seal groove A, seal groove B are located straight tube A.

Further, the straight pipes A and B are made of aluminum metal materials, and internal threads are arranged inside the straight pipes A and B.

Further, the diameter of the straight pipe A is larger than that of the straight pipe B.

Further, the sleeve is a detachable sleeve.

Further, the joints a, B and C are set with an accuracy of +0.05 mm.

Further, the seal groove a and the seal groove B are of the same type.

The utility model has the advantages that: the joint design accuracy of the double-sealing joint of the automobile air conditioner is reset to be +0.05 mm from the original +0.12 mm, the sealing grooves are changed into two groups from a group of original single-sealing joint, the risk of pipeline leakage is greatly reduced, and the leakage-proof design requirement for engine cooling is met.

Drawings

Fig. 1 is a schematic view of the cross-sectional structure of the present invention.

In the figure: the sealing grooves A and B are formed by 1 straight pipe A, 2 straight pipe B, 3 sleeves, 4 joints A, 5 joints B, 6 joints C, 7 and 8.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the double-sealing joint for the automobile air conditioner comprises a straight pipe a1, a straight pipe B2, a sleeve 3, a joint a4, a joint B5, a joint C6, a sealing groove a7 and a sealing groove B8, wherein the straight pipe a1 is arranged at the right part of the sleeve 3, the straight pipe B2 is arranged at the left part of the sleeve 3, the joint a4 is arranged at the top of the straight pipe a1, the joint B5 is arranged at the top of the straight pipe B2, the joint C6 is arranged at the bottom of the straight pipe B2, the sealing groove a7 and the sealing groove B8 are arranged at the upper right part of the sleeve 3, and the sealing groove a7 and the sealing groove.

In the utility model, the straight pipe A1 and the straight pipe B2 are both made of aluminum metal materials, the straight pipe A1 and the straight pipe B2 are internally provided with internal threads, and the straight pipe A1 and the straight pipe B2 are firmly and stably assembled; the diameter of the straight pipe A1 is larger than that of the straight pipe B2, so that the assembly is convenient; the sleeve 3 is a detachable sleeve, so that the replacement and use of the new sleeve and the old sleeve are convenient, and the pipeline installation is convenient; the setting precision of the joint A4, the joint B5 and the joint C6 is +0.05 mm, so that the assembly precision of the internal pipeline of the automobile air conditioner is improved, and the risk of pipeline leakage is reduced; the sealing groove A7 and the sealing groove B8 are of the same type, and sealing effect is enhanced.
