Abstract
The invention provides a compressor and an air conditioner. The compressor disclosed by the invention comprises a cylinder, wherein the cylinder is provided with a cylinder spring hole; a fixing structure for fixing the outer end of a pump spring is arranged inside the cylinder spring hole. According to the compressor disclosed by the invention, the fixing structure for fixing the outer end of the pump spring is arranged inside the cylinder spring hole, so that the pump spring does not lean against a shell; therefore, the pump spring has no interference with a lug boss on the shell, the pump spring is ensured to work reliably, and the reliability of the compressor and the air conditioner is improved.
Description
Technical field
The present invention relates to field of air conditioning, in particular to a kind of compressor and air-conditioning.
Background technique
During existing compressor general assembly, can withstand inner walls after pump spring assembling, move back and forth, spring can't lose efficacy.Along with the propelling of compressor miniaturization and housing sucking pipe resistance welding structure, now develop in light duty compressor process, the welding of housing sucking pipe changes resistance welding into by induction welding, housing then needs the boss going out certain altitude and width as welding plane, if boss width is too little very large on resistance welding impact, easily occur that not prison welding is solid; If boss width is too large, the pump spring after may causing boss and assembling is interfered, and part is unsettled even all unsettled to cause pump spring to occur, easily causes spring force inequality or spring to eject Problem of Failure.
Summary of the invention
The present invention aims to provide a kind of compressor and the air-conditioning that can improve reliability.
The invention provides a kind of compressor, comprise cylinder, cylinder has cylinder spring eye, be provided with in cylinder spring eye the fixing fixed structure in the outer end of pump spring.
Further, fixed structure is the internal thread coordinated with pump spring, and after installation, pump spring is fixed in the thread groove of internal thread.
Further, the diameter of the spring thread of pump spring is g, and the depth of threat of internal thread is h, wherein, and h > g.
Further, the diameter of the spring thread of pump spring is g, and the outer end of pump spring has N and encloses doubling-up, and the pitch of internal thread is P, wherein, and P > Ng.
Further, fixed structure is the interface arrangment being arranged on cylinder spring eye outer end.
Further, fixed structure is for being arranged on cylinder spring eye outer end sunk screw structure.
Present invention also offers a kind of air-conditioning, comprise aforesaid compressor.
According to compressor of the present invention and air conditioner, by arranging the fixing fixed structure in the outer end of pump spring in cylinder spring eye, pump spring is no longer conflicted on housing, thus avoid the boss on pump spring and housing to interfere, ensure pump spring reliably working, improve the reliability of compressor and air-conditioning.

Embodiment
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figures 1 to 4, according to compressor of the present invention, comprise cylinder 10, cylinder 10 has cylinder spring eye 20, be provided with in cylinder spring eye 20 the fixing fixed structure in the outer end of pump spring 30.The present invention by arranging the fixing fixed structure in the outer end of pump spring 30 in cylinder spring eye 20, pump spring 30 is no longer conflicted on housing, thus avoid pump spring 30 to interfere with the boss on housing, ensure pump spring 30 reliably working, improve the reliability of compressor and air-conditioning.
Preferably, fixed structure is the internal thread 21 coordinated with pump spring 30, and after installation, pump spring 30 is fixed in the thread groove of internal thread 21.Namely cylinder 10 of the present invention processes one section of screw thread at the afterbody of cylinder spring eye 20, after pump spring 30 assembles, pump spring 30 stub end (outer end) can be used to be nested in tapped hole, spring forms self-locking at cylinder, no longer rely on and withstand inner walls, solve the excessive or too small problem brought of housing boss welding plane, if boss width is too little very large on resistance welding impact, easily occur that not prison welding is solid; If boss width is too large, after pump spring assembling, occur that part is unsettled even all unsettled, easily cause spring force inequality or spring to eject Problem of Failure; In cylinder spring eye, pump spring can according to setting depth, the position screwing the degree of depth and come Regulation spring, and greatly improve the versatility of spring, different series compressor can use same spring, screws the degree of depth by regulating;
Preferably, if spring stub end is and tight two circles, the then pitch P > twice wire diameter (i.e. 2g) of internal thread 21, by that analogy, if spring stub end is and tight N circle, then internal thread 21 pitch P >N times of wire diameter (i.e. Ng), and pitch P is also unsuitable excessive, ensures that spring stub end can embed tapped hole completely; The internal thread 21 depth of threat degree of depth is slightly larger than wire diameter g; The rotation direction of screw thread is consistent with spring, is generally dextrorotation.
Preferably, in other embodiments of the invention, fixed structure also for being arranged on the interface arrangment of cylinder spring eye 20 outer end, can be able to realize requirement fixing for pump spring 30 equally.Fixed structure can also, for being arranged on cylinder spring eye 20 outer end sunk screw structure, adopt sunk screw also to can be good at pump spring 30 to fix.
Present invention also offers a kind of air-conditioning, comprise aforesaid compressor, pump spring is no longer conflicted on housing, thus avoid the boss on pump spring and housing to interfere, ensure pump spring reliably working, improve the reliability of compressor and air-conditioning.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
According to compressor of the present invention and air conditioner, by arranging the fixing fixed structure in the outer end of pump spring in cylinder spring eye, pump spring is no longer conflicted on housing, thus avoid the boss on pump spring and housing to interfere, ensure pump spring reliably working, improve the reliability of compressor and air-conditioning.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
