Description
Technical field
The utility model belongs to compressor accessory technical field, and in particular to a kind of compressor socket joint type rolling piston.
Background technology
Rolling piston is the important part of rotary compressor for refrigerant set, and the bias being arranged in the eccentric shaft of compressor turns
On, when refrigeration, rolls along cylinder wall, and for slide plate under spring force with the outer circle wall surface close contact of rolling-rotor, composition is dynamic
Sealing, with rotary compressor using novel environment-friendly refrigerant, high efficiency and it is energy saving etc. become more diverse, to can be suitably used for height
More stringent requirements are proposed for rolling piston under the rigor conditions such as load, high power, high temperature, high pressure.For a long time, rolling piston
It is all made of metal, weight is big.And it is driving rolling piston rotation, it needs to spend more energy, but live due to rolling
Plug, which needs to have preferable frictional behaviour again, higher intensity, therefore does not up to the present also find a kind of saving energy
Effective ways.
A kind of patent compressor rolling piston and its manufacturing method (notification number CN105257544A) include interior cylinder,
Outside cylinder, the injected plastics material for being less than steel or iron between interior cylinder and outside cylinder by density are molded one, so that
The weight of entire piston can mitigate significantly, but due to injection molding during, due to the opposite position between two cylinders
It sets and often changes, and the alignment of central axis is more difficult, therefore, to produce the rolling piston of standard, just need to consume
Time-consuming fixation.
Therefore it is simple in structure to be badly in need of one kind, it is convenient for production, and the compressor of lighter in weight socket joint type rolling piston.
Utility model content
The purpose of this utility model is to provide a kind of compressor socket joint type rolling piston, simple in structure, convenient formation, and
Lighter in weight.
The utility model provides the following technical solution：
A kind of compressor socket joint type rolling piston, including interior cylinder and outside cylinder, the outer wall of interior cylinder, which is equipped with, to close
The first card slot is distributed in the axisymmetrical of interior cylinder, the inner wall of outside cylinder is equipped with abuts against cooperation with the side of the first card slot
Fixture block, the injected plastics material for being less than steel or iron between interior cylinder and outside cylinder by density is molded.
Preferably, the first card slot is identical as the length of fixture block, and the gap width being equal between outside cylinder and interior cylinder,
Make it possible to achieve when interior cylinder is placed on inside outside cylinder, you can to realize that central axis coincides, to realizing so that
Interior cylinder and overlapping for outer circle mast axis are more convenient, to which injection moulding process is more time saving and energy saving.
Preferably, the second card slot being distributed with the first card slot parallel and symmetrical, and first are additionally provided on the outer wall of interior cylinder
Card slot and the second card slot are fitted in the both sides of fixture block respectively, so that the fixation between interior cylinder and outside cylinder is more firm.
Preferably, the material of the first card slot and the second card slot is thermosetting plastics so that the overall structure of rolling piston
It is more light.
The utility model has the beneficial effects that：By the way that mutually matched first card is arranged between interior cylinder and outside cylinder
Slot and fixture block may be implemented realization and are relatively fixed, and coordinate so that in injection molding between interior cylinder and outside cylinder
Second card slot, and by fixture block setting card and between the second card slot and the first card slot, so that between interior cylinder and outside cylinder
Fixation it is more firm, and when the gap between the first card slot and the length of fixture block and interior cylinder and outside cylinder is identical, to
It realizes so that interior cylinder and overlapping for outer circle mast axis are more convenient, to which injection moulding process is more time saving and energy saving.
Description of the drawings
Attached drawing is used to provide a further understanding of the present invention, and a part for constitution instruction, with this practicality
Novel embodiment for explaining the utility model, does not constitute limitations of the present invention together.In the accompanying drawings：
Fig. 1 is the top plan view of the utility model；
Fig. 2 is the main view sectional view of the utility model
Label in figure：10 be interior cylinder, and 20 be outside cylinder, and 30 be the first card slot, and 40 be fixture block, and 50 be the second card slot.
Specific implementation mode
In conjunction with Fig. 1 to a kind of compressor socket joint type rolling piston shown in Fig. 2, in the present embodiment, including interior cylinder
10 and outside cylinder 20, the outer wall of interior cylinder 10 is equipped with is distributed with the first card slot 30 about the axisymmetrical of interior cylinder 10, outside
The inner wall of cylinder 20 is equipped with the fixture block 40 that cooperation is abutted against with the side of the first card slot 30, between interior cylinder 10 and outside cylinder 20
The injected plastics material for being less than steel or iron by density is molded, and the first card slot 30 is identical as the length of fixture block 40, and is equal to outer circle
Gap width between column 20 and interior cylinder 10 so that when may be implemented interior cylinder 10 being placed on 20 inside of outside cylinder, you can
To realize that central axis coincides, to realize so that interior cylinder 10 and overlapping for 20 axis of outside cylinder are more convenient, to note
Modeling process is more time saving and energy saving, and the second card slot being distributed with 30 parallel and symmetrical of the first card slot is additionally provided on the outer wall of interior cylinder 10
50, and the first card slot 30 and the second card slot 50 are fitted in the both sides of fixture block 40 respectively, so that interior cylinder 10 and outside cylinder 20
Between fixation it is more firm, the material of the first card slot 30 and the second card slot 50 is thermosetting plastics so that rolling piston
Overall structure is more light.
The operation principle of the utility model is：Interior cylinder 10 is directed at the first card slot 30 and the second card slot according to by fixture block 40
The mode in 50 gap is put into outside cylinder 20, at this point, interior cylinder 10 is overlapped with the shaft core of outside cylinder 20, and relative position is solid
It is fixed, it is more time saving and energy saving in injection molding.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
Technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this practicality
Within novel protection domain.
