Environment is taken, journey fatigue is reduced；Good operating condition is created for driver, to ensuring what safe driving played an important role
Ventilation device.
Air conditioning for automobiles work flows refrigerant in air-conditioning duct by compressor, to realize heat exchange.Air conditioning for automobiles
Pipeline it is unified assembled by prefabrication, pipeline during transportation, to avoid polluting in pipeline, it usually needs in pipe
Dust cover is set on pipeline connector, existing dust cover structure such as Fig. 1, the inner wall and handle part of dust cover are smooth, once it is dust-proof
The internal diameter of cover is too small, and dust cover is not on facility for nesting to connector, and the internal diameter of dust cover is too big, so that dust cover is easy on transport way
In fall off.When removing dust cover, since handle part is smooth, it is not easy to operator's gripping, so that disassembly is inconvenient.
Utility model content
In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide a kind of knot
Rationally, convenient for suit, not easily to fall off, convenient disassembly is conducive to the air conditioning for automobiles for improving protection effect and disassembly efficiency for structure design
Pipe joint plastic dust cap.
In order to solve the above-mentioned technical problem, the utility model uses the following technical solution:
A kind of automobile air conditioner pipeline connector plastic dust cap is gone back on the cover including whole cylindrical cover
With tie rod, the tie rod is radially connected on the outside of the open end of the cover；The internal diameter of the cover and pipe joint
Outer diameter is consistent, and the cover is enable to be sleeved on pipe joint；It is characterized in that, the inner wall of the cover has been provided projectingly bullet
Property boss, the boss is multiple along circumferentially having for the cover, and the inscribed circle diameters of multiple boss is less than pipeline
The diameter of connector, and can cover on pipe joint, when being sleeved on the cover on pipe joint, the boss is in compression
State.
In this way, in use, by the open end alignment pipe joint indentation of cover, since the end of pipeline structure all has down
Angle, boss squeezes under the guiding role of pipe joint end-beveling, and covers on pipe joint, and boss is in by compression shape
State tightly embraces pipe joint, during transportation, is all not easy to be shaked off and fallen off, and when disassembly, holds tie rod and is drawn
It pulls, so that it may cover be unloaded, convenient disassembly from pipe joint, be conducive to improve protection effect and disassembly efficiency.
Further, the tie rod has convex along being formed perpendicular to length direction protrusion away from one end of the cover
Rib.
In this way, using the prominent fin formed in tie rod end, can be effectively prevented when pullling tie rod, tie rod surface excessively light
It slides and skating, convenient for pullling tie rod.
Further, the open end of the cover has the flange of radially prominent formation, and the tie rod is connected to
On the flange.
In this way, can both increase the intensity of cover open end, during avoiding tie rod from pullling, the open end of cover is drawn
It splits.Again during being set with cover, using the prominent flange formed, the frictional force of finger push cover can be increased, be convenient for
The suit of cover.
Further, drawstring is integrally embedded in the tie rod, the drawstring is arranged along the length direction of the tie rod, and
The open end end of the cover is integrally embedded in close to one end of the cover.
In this way, since drawstring is integrally embedded in the open end end of tie rod and cover, it is embedded using one when pullling tie rod
Drawstring, can will directly pull power and be applied on cover, convenient for the disassembly of cover, and can pull tie rod to avoid when pullling
It is disconnected, improve the service life of dust cap.
Further, the drawstring is embedded in along the circumferential of the cover to two sides with extending close to one end of the cover
In the cover, and it is less than the half of the cover perimeter in the intracorporal whole built-in length of the cover.
In this way, cover can be pulled open using drawstring close to the half side of tie rod when pullling tie rod, draw the open end of cover
Greatly, deviate from pipe joint convenient for dust cover, dismantle more convenient.
Further, multiple boss are circumferentially connected to integrally, and the boss is on the shaft section of the cover
Shape be arc-shaped or triangle.
Further, the boss is disposed at least two along the axial direction of the cover.
Further, the surface of the tie rod has multiple raised lines or salient point convexed to form.
Further, the raised line is arranged along the width direction of the tie rod.
Further, the drawstring integrated injection molding is in the cover and tie rod.
In conclusion the utility model have it is reasonable in design, convenient for suit, not easily to fall off, convenient disassembly is conducive to
The advantages that improving protection effect and disassembly efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing dust cover.
Fig. 2 ~ Figure 11 is the schematic diagram of the different structure of the utility model.
Figure 12 is the structural schematic diagram of the utility model dust cover installation condition.
