Description
Technical field
A kind of compressor is the utility model is related to, more particularly, to a kind of piston compressor with universal ball link.
Background technology
Either refrigerator, or the refrigeration plant such as refrigerator, their " heart " are a Totally-enclosed piston type compressors.And
What driving refrigerant flowed is the piston in " heart ".Piston is driven by bent axle, and by the transmission of connecting rod power, driving piston is in cylinder
Make flexible reciprocal linear motion in vivo.
Because crank rotates under the drive of power set, the crank axle being connected with connecting rod is that circumference fortune is done in a plane
It is dynamic, and piston is in linear motion.Also just say, one end of connecting rod and crank axis connection is to move in a circle, connecting rod and work
The other end of plug connection is then to move along a straight line, and whole connecting rod is compound motion.The non-rectilinear fortune that the compound motion of connecting rod is brought
The external force in dynamic direction can bring certain interference to piston.In order to ensure the stability of piston movement, to the machining accuracy of connecting rod
It is it is required that high, therefore, to assure that the depth of parallelism of piston pin hole and crankshaft hole on connecting rod.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of piston compressor with universal ball link, right

It is provided with contiguous block, described contiguous block is provided centrally with chondritic, the cavity being adapted with multi-directional ball axle, and described ten thousand
It is arranged on to ball axle in cavity, described multi-directional ball axle can relatively rotate in the cavity of contiguous block, in described piston
Notch is set, and the center of described notch is provided with the piston pin of column structure, and the other end of described connecting rod is penetrated outside notch
It is enclosed in piston pin, the other end of connecting rod can rotate in notch around piston pin.
The further preferred scheme of the utility model：Described crank is cylindrical-shaped structure, and described multi-directional ball axle is ball
It is enclosed on outside shape structure on crank.
The further preferred scheme of the utility model：Described notch is the middle part that cyclic structure surrounds piston pin lateral surface
Set, the both ends of described piston pin, which are stuck in piston, makes piston radially irremovable.
The further preferred scheme of the utility model：Lateral pin is provided with described piston, lateral pin is lived through piston insertion
In plug pin.
The further preferred scheme of the utility model：Discharge chamber and suction muffler are connected on described cylinder.
The further preferred scheme of the utility model：Air bleeding valve is provided between described discharge chamber and cylinder, it is described
Inlet valve is provided between suction muffler and gas.
Compared with prior art, the utility model has the advantage of multi-directional ball axle, connecting rod one are installed with outside crank
End is provided with contiguous block, and contiguous block is provided centrally with chondritic, the cavity being adapted with multi-directional ball axle.Multi-directional ball axle is pacified
In cavity, multi-directional ball axle can relatively rotate in the cavity of contiguous block.The setting of said structure, in contiguous block
When the precision of cavity processing is not high, it can also meet compressor motion stabilization.
Notch is set in piston, and the center of notch is provided with the piston pin of column structure, and the other end of connecting rod penetrates groove
It is enclosed on outside mouthful in piston pin, the other end of connecting rod can rotate in notch around piston pin.Said structure is set so that connecting rod is another
The adaptability of the piston pin hole at end is high.The utility model structure setting can suitably be relaxed to the machining accuracy of parts, special
Be not the cavity of connecting rod and the depth of parallelism of crankshaft hole be no longer required for it is so high.The utility model changes to compressor arrangement
Enter so that mass motion is more stable, so as to improve the performance of product.
