Abstract
The pipe joint of a kind of refrigerant pipe of the utility model, containing pipeline and nut pier nose, the front end of described pipeline is flaring structure, is provided with flange on the top of enlarging; Be provided with groove in described nut pier nose inside, the shape of the similar described enlarging of shape of described groove, the opening of groove is horn-like structure; The external diameter of described pipeline enlarging is less than the diameter of described nut pier nose interior grooves; Be socketed in by its flaring structure in the groove of nut pier nose by pipeline, river flange is connected on the opening of the horn-like structure of groove, utilizes pier to be installed with standby assembly.The utility model, by structural improvement, makes pipe coupling disposable pier pressure can connect shaping and have hermetic effect, avoids the situation of product leakage; Instead of welding procedure with pier compression technology, effectively can not only reduce cost of production, reduce potential safety hazard, and can production environment be protected, be conducive to the health of workman, manufacturing efficiency and quality of product can be significantly improved.
Description
Technical field
The utility model relates to air-conditioning duct link technical field, particularly relates to the refrigeration pipe of car air conditioner, particularly a kind of pipe joint of automobile air conditioner refrigerating pipe road.
Background technique
Air-conditioning equipment is one of equipment generally used at present.Due to structural needs, air-conditioning equipment can use many pipelines and pipe joint (pipe joint).Car air conditioner belongs to the large class of one in air-conditioning equipment.The pipe joint that current automobile air conditioner refrigerating pipe road uses is mainly with the pipe joint that welding manner connects, and its pipe fitting 11 is after putting by production requirement with nut connector 12, with the mode welding fabrications such as solder welding wire heating (see Fig. 1).The deficiency of this refrigerant pipe pipe joint is: the easy not prison welding of (1) pipe fitting and weld joint, produces and leaks, affect quality of product; (2) welding procedure cost is higher, need take the more resources of production (comprising welding technique personnel, welding raw material, combustion gas etc.); (3) combustion gas is deposited and is easily produced safety problem; (4) welding time produce waste gas can pollute surrounding enviroment, to the health of operator and the environmetal impact of periphery larger; (5) technological requirement is high, and processing speed is slow, cannot enhance productivity.
Model utility content
The purpose of this utility model is to solve the problem, and provides a kind of pipe joint of refrigerant pipe, and it is by the improvement of pipe joint structure, pipe coupling disposable pier pressure can be connected shaping and has had hermetic effect, avoid the situation of product leakage; In addition, it substitutes welding procedure with upsetting technique, effectively can reduce cost of production, reduces potential safety hazard, is conducive to the health of environmental protection and operator, can significantly improves quality of product and manufacturing efficiency.
For realizing above-mentioned object, the utility model have employed following technological scheme.
A pipe joint for refrigerant pipe, containing pipeline and nut pier nose, is characterized in that, the front end of described pipeline is flaring structure, is provided with flange on the top of described enlarging; Be provided with groove in described nut pier nose inside, the shape of the similar described enlarging of shape of described groove, the opening of described groove is horn-like structure; Described pipeline is socketed in the groove of described nut pier nose by its flaring structure, and described flange is connected on the opening of the horn-like structure of described groove, utilizes pier to be installed with standby assembly.
Further, the external diameter of described pipeline enlarging is less than the diameter of described nut pier nose interior grooves.
Further, the lower edge of the flange on described pipeline enlarging top is the little inclined-plane in 30 °.
Further, the opening of the horn-like structure of described nut pier nose groove is the inclined-plane in 30 °.
The good effect of the pipe joint of a kind of refrigerant pipe of the utility model is:
(1) by the improvement of pipe joint structure, pipe coupling disposable pier pressure can be connected shaping and had hermetic effect, avoid the situation of product leakage.
(2) use upsetting technique to substitute welding procedure in the fabrication process, effectively can reduce cost of production, minimizing potential safety hazard, prevent operator go to bits and surrounding enviroment influenced.
(3) easy to make, manufacturing efficiency and quality of product can be significantly improved, be easy to applying of product.

Embodiment
Explain the embodiment of the pipe joint of a kind of refrigerant pipe of the utility model below in conjunction with accompanying drawing further, but it is noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 4.A pipe joint for refrigerant pipe, containing pipeline 21 and nut pier nose 24, described pipeline 21 and described nut pier nose 24 adopt aluminium matter or copper structural member usually.
First utilize general pier to be installed with standby, enlarging 22 structure (see Fig. 2) is made in the front end of described pipeline 21: pipeline 21 front end outwards launches first to form a toy trumpet shape structure, and the wall of toy trumpet shape construction stretch is the wall of described enlarging 22; Arrange a flange 23 on the top of described enlarging 22, described flange 23 is typhon shape structure, its lower little inclined-plane along being designed in 30 degree.
Described nut pier nose 24 is made the structural member of inner fluted 25: the shape of the similar described enlarging 22 of shape of described groove 25, the opening 26 of described groove 25 is made horn-like structure (see Fig. 3); Its opening 26 can be designed to the inclined-plane in 30 degree, the laminating of convenience and described pipeline 21 enlarging 22 upper overturning 23.
Should note in enforcement: the external diameter of described pipeline 21 enlarging 22 should be less than the diameter of described nut pier nose 24 interior grooves 25, to facilitate, described pipeline 21 is socketed in described nut pier nose 24.
Described pipeline 21 is socketed in the groove 25 of described nut pier nose 24 by its enlarging 22 structure, described flange 23 is connected on the opening 26 of the horn-like structure of described groove 25, pier is utilized to be installed with standby assembly: to utilize general pier to be installed with standby, the corresponding pier of coupling is used to rise mould, described pipeline 21 is carried out mating pier with described nut pier nose 24 rise, make described pipeline 21 fit tightly fastening with described nut pier nose 24, complete the processing (see Fig. 4) of pipe joint.
The utility model utilizes pier pressure (pier rises) technique to instead of original welding procedure, more advanced in the mode of production, effectively can not only reduce cost of production; reduce potential safety hazard; and can production environment be protected, be conducive to the health of workman, manufacturing efficiency and quality of product can be significantly improved.
