Description
Technical field
The utility model relates to automobile air conditioning technology fields, specifically, being a kind of no-welding air-conditioner pipe.
Background technique
Automobile air regulating device abbreviation air conditioning for automobiles, in automobile bodies temperature, humidity, air cleanliness and
Air flow adjustment and control provide comfortable seating environment for occupant, reduce journey fatigue, create for driver in optimum state
Good operating condition is made, to the ventilation device for ensuring that safe driving plays an important role.Generally comprise refrigerating plant, heating dress
It sets and compound ventilation air-changing device.This combined unit takes full advantage of the limited space of automotive interior, and structure is simple, convenient for operating,
It is modern cars air-conditioning system popular in the world.
Pipeline is can't do without in connection in existing air conditioning for automobiles between all parts, mostly uses welded connecting greatly between pipeline
Mode, since air conditioning for automobiles space is limited, pipeline diameter is smaller, this is relatively high to welding process requirement, and, welding
It is easy to cause pipeline unnecessary injury in journey, the leakproofness for destroying pipeline in welding process or air-conditioning are in use process
In, weld part generates gap, this can all impact the normal work of air-conditioning, serious or even can greatly shorten making for air-conditioning
Use the service life.
Utility model content
In order to solve the above-mentioned technical problem, the utility model discloses a kind of no-welding air-conditioner pipe, in air conditioning for automobiles
The connection of all parts reduces production technology, reduces production cost.
To achieve the goals above, the specific technical solution that the utility model uses is as follows:
A kind of no-welding air-conditioner pipe, including long tube, one end of long tube are provided with boss, and the internal diameter of boss is greater than the interior of long tube
Diameter, boss are connect by the way of integrally casting with long tube, and the periphery of boss is provided with multiple protrusions.
In the technical scheme, it is combined together by the way of integrally casting between long tube and boss, avoids having the gap
Generation, strengthen leakproofness, be provided with protrusion in the periphery of boss convenient for connecting with air-conditioning pipe fitting, protrusion is stuck in air-conditioner pipe
In the groove of connector, so that the connection between air-conditioner pipe and air-conditioning pipe fitting is stronger, leakproofness is better.
Further improvement of the utility model, protrusion are uniformly arranged on the periphery of boss, it is the distance between raised two-by-two
Equal, the protrusion that is uniformly arranged is further such that the connection between air-conditioner pipe and air-conditioning pipe fitting is better, uniform force, more
Securely.
The edge setting of further improvement of the utility model, boss is fluted, and the setting of groove can be used to be stuck in
Inside air-conditioning pipe fitting, further reinforce the connection between air-conditioner pipe and air-conditioning pipe fitting, groove setting two protrusions it
Between.
The utility model has the beneficial effects that no-welding air-conditioner pipe and matched air-conditioner pipe that the utility model discloses connect
Connection between head is stronger and seals, and saves the welding procedure between air-conditioning duct in this way, reduces cost of labor, subtracts
The small probability for causing pipeline to reveal because of welding, so that the connection between pipeline is simpler, quick, efficient, so that whole
The production of a air conditioning for automobiles reduces costs, and improves quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1- long tube, 2- boss, 3- protrusion, 4- groove.
Specific embodiment
In order to deepen the understanding to the utility model, the utility model is done further below in conjunction with drawings and examples
Detailed description, the embodiment are only used for explaining the utility model, do not constitute and limit to the protection scope of the utility model.
Embodiment: as shown in Figure 1, a kind of no-welding air-conditioner pipe, including long tube 1, one end of long tube 1 is provided with boss 2, convex
The internal diameter of platform 2 is greater than the internal diameter of long tube 1, and boss 2 is connect by the way of integrally casting with long tube 1, and the periphery of boss 2 is provided with
Multiple raised 3, it is combined together by the way of integrally casting between long tube 1 and boss 2, avoids apertured generation, reinforced
Leakproofness is provided with protrusion 3 in the periphery of boss 2 and is stuck in the recessed of air-conditioning pipe fitting convenient for connect with air-conditioning pipe fitting, raised 3
In slot 4, so that the connection between air-conditioner pipe and air-conditioning pipe fitting is stronger, leakproofness is better.
In the present embodiment, the periphery that protrusion 3 is uniformly arranged on boss 2, protrusion 3 the distance between it is equal two-by-two,
For the protrusion 3 of even setting further such that the connection between air-conditioner pipe and air-conditioning pipe fitting is better, uniform force is stronger；
Groove 4 is additionally provided between two protrusions 3, the setting of groove 4 can be used to be stuck in inside air-conditioning pipe fitting, further reinforce
Connection between air-conditioner pipe and air-conditioning pipe fitting.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this
The principle of utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various change
