Abstract
This invention relates to the field of automobile pipeline joint technology especially a kind of quick joint of automobile air conditioning pipeline that is featured by a locking ring at one end of the main part of the pipeline, a circular spring inside the locking ring, at least one O-shaped ring on the surface of one end of the pipeline, a flared end and a flanging on one end of the sliding barrel. During test this joint can bear a pressure of 4.0MPa comparing the common pressure of 2.5 MPa. The bursting pressure achieves 14MPa far above the technological requirements. When assembling, the flared end and the flanging on one end of the sliding barrel is inserted into the locking ring and the circular spring will lock the flanging and the connection is completed within 1 second, which increase the efficiency remarkably.
Description
Technical field
The present invention relates to automobile pipe joint technical field, especially relate to a kind of pipeline fast joint of automobile air conditioner.
Background technique
As everyone knows, automobile air conditioning system, from the compressor to the condenser, to vaporizer a plurality of pipeline tie points are arranged again, and pipeline inside to bear certain pressure, generally speaking, the pressure of automotive air-conditioning system internal operation is 0.8～2.5Mpa, in the prior art, between pipeline in, outer tube connects the traditional flange-type connection of most of employing or is threaded, and the course of working complexity that is threaded, processing request height not only, and double thread intensity has suitable high request, and when pipeline was linked and packed, the most skilled operator wanted for 10 seconds at the soonest, therefore the Placement installation time is long like this, labor intensity is big, and manufacturing efficiency is low, and the manufacture cost height.
Summary of the invention
Purpose of the present invention overcomes above-mentioned the deficiencies in the prior art, a kind of pipeline fast joint of automobile air conditioner is provided, it is changed into easy plug-in type with loaded down with trivial details being threaded and connects under the situation that satisfies pipe internal pressure and join strength, can improve the work efficiency of assembling greatly.
To achieve these goals, technological scheme of the present invention is: a kind of pipeline fast joint of automobile air conditioner, constitute by pipeline main body and the sliding barrel that can insert the pipeline main body, it is characterized in that: the side end in the pipeline main body is provided with locking ring, a ring-spring is set in locking ring, side end outer surface in pipeline main body (1) is provided with an O RunddichtringO at least, at a side end of sliding barrel an enlarging and a circle flange is set.
The present invention is on probation on the car air conditioner pipeline, the internal pressure of general automotive air-conditioning system is no more than 2.5Mpa, and this joint checks that pressure reaches 4.0Mpa and do not leak, the bursting pressure that test reaches is 14Mpa, substantially exceeded technical requirements, during assembling, as long as a side end enlarging and a circle flange of sliding barrel are inserted in the side end locking ring of pipeline main body, clickly one, the ring-spring in the locking ring blocks a circle flange of sliding barrel, can finish connection, the general operation personnel only need the time in 1 second, improved work efficiency greatly, the work of being linked and packed is saved time, laborsaving, more reliable.
Description of drawings
Fig. 1 is the connection sectional view of the embodiment of the invention;
Fig. 2 is the sectional view of taking apart of the embodiment of the invention.
Among the figure, 1, the pipeline main body, 2, locking ring, 3, ring-spring, 4, the O RunddichtringO, 5, the O RunddichtringO, 6, enlarging, 7, sliding barrel, 8, flange, 9, O type groove, 10, O type groove, 11, protruding circle.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
With reference to accompanying drawing, the embodiment of the invention is by pipeline main body (1) and can inserts sliding barrel (7) formation of pipeline main body (1), it is characterized in that: extrude a protruding circle (11) at pipeline main body (1) one side end cold punching, protruding circle (11) can play position-limiting action, again protruding circle (11) the other end pipeline main body (1) is enlarged, fixed locking ring (2); The ring-spring (3) of in locking ring (2), packing into, ring-spring (3) external diameter is slightly larger than the bore of locking ring (2), and ring-spring (3) just can not come off in locking ring (2); Pipeline main body (1) one side end expansion section surface especially is provided with O type groove (9) and O type groove (10), generally can adopt roll forming, the internal diameter of O type sealing (4) and O RunddichtringO (5) is slightly less than O type groove (9) and footpath, O type groove (10) end, and O RunddichtringO (4) and O RunddichtringO (5) are embedded in respectively in O type groove (9) and the O type groove (10); A side end cold stamping enlarging (6) and a circle flange (8) to sliding barrel (7), sliding barrel (7) one circle flange (8) maximum outside diameters are slightly less than footpath in the ring-spring (3), sliding barrel (7) is stressed with ring-spring (3) like this, ring-spring (3) external diameter is greater than the bore of locking ring (2), just locate to upspring and entangle, thereby played interconnect function to a circle flange (8) of sliding barrel (7); Sliding barrel (7) is unloaded down from pipeline main body (1), with a private key circle flange (8) that ring-spring (3) ejects sliding barrel (7) is located, ring-spring (3) shrinks with a circle flange (8) of sliding barrel (7) to be located to separate, and can unload down.
Claims (3)
1. pipeline fast joint of automobile air conditioner, constitute by pipeline main body and the sliding barrel that can insert the pipeline main body, it is characterized in that: the side end in the pipeline main body is provided with locking ring, a ring-spring is set in locking ring, side end outer surface in the pipeline main body is provided with an O RunddichtringO at least, at a side end of sliding barrel an enlarging and a circle flange is set.
2. a kind of pipeline fast joint of automobile air conditioner according to claim 1 is characterized in that: the side end outer surface in the pipeline main body is provided with an O type groove at least, and the O RunddichtringO is embedded in the O type groove.
3. a kind of pipeline fast joint of automobile air conditioner according to claim 1 is characterized in that: the side end in the pipeline main body also is provided with a protruding circle.
