Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, is only used for explaining the utility model, and it is not intended that to of the present utility model
Limitation.
Compressor 100 below with reference to Fig. 1-Fig. 4 descriptions according to the utility model embodiment.
As shown in figure 1, according to the compressor 100 of the utility model embodiment, including housing 1 and the pump that is located in housing 1
Body 2, the pump housing 2 include compression mechanism 21 and motor 22, and compression mechanism 21 has rotary shaft 221 and supports the machine of rotary shaft 221
Frame 222, for the pump housing 2 by spring supporting in housing 1, housing 1 is provided with the first position limitation protection in the side towards compression mechanism 21
Component 3, housing 1 are provided with the second position limitation protection component 4 in the side towards motor 22, and two position limitation protection components correspond to respectively
The both ends of rotary shaft 221 are set, to avoid the pump housing 2 from being collided at the both ends of rotary shaft 221 with the phase of housing 1.
It is understood that, compressor 100 is easy to vibrate in compressor 100 in transit.Work as compressor
100 when vibrating, and rotary shaft 221 is also vibrated therewith.If being not provided with position limitation protection component, the both ends of rotary shaft 221 hold very much
Easily collided with housing 1, so impact can have adverse effect on to rotary shaft 221 and housing 1, so as to influence compressor
100 reliability.Thus, the both ends of corresponding rotation axle 221 set position limitation protection component, equivalent to limiting rotary shaft 211
Vibration, the both ends and the phase of housing 1 for avoiding rotary shaft 221 are collided.
In addition, rotary shaft 221 is the axial connecting part between compression mechanism 21 and motor 22, rotary shaft 221 is located at shell
The center of body 1, it may be said that rotary shaft 221 takes on the effect of the centre strut of the pump housing 2.When setting first on housing 1
The position limitation protection component 4 of position limitation protection component 3 and second, after being restricted the Oscillation Amplitude of rotary shaft 221, is connected to rotary shaft
The Oscillation Amplitude of the parts such as the rotor on 221 is also restricted, therefore can effectively avoid the pump housing 2 from being rushed with the phase of housing 1
Hit.
According to the compressor 100 of the utility model embodiment, due to being provided with spacing guarantor at the both ends of corresponding rotation axle 221
Protecting assembly so that in the transportation of compressor 100, the pump housing 2 of compressor 100 is not easy to rock, and avoids the pump housing 2 and housing 1
Mutual collision, improve the reliability of compressor 100.
In certain embodiments, it is at least one in two position limitation protection components to be provided with the elasticity being enclosed on outside in rotary shaft 221
Set, so, resilient sleeve can produce the effect of radial constraint to rotary shaft 221, and resilient sleeve is to will not be hard between rotary shaft 221
Property collision, avoid producing excessive foreign matter.
Alternatively, resilient sleeve is helical spring.The coefficient of elasticity of helical spring is larger, and rigidity is also larger, can be preferably
The transportation middle pump body 2 of buffer compression machine 100 and impulsive force caused by the collision of the phase of housing 1.
It should be noted that can include resilient sleeve in two position limitation protection components, also may be used in two position limitation protection components
Only one component includes resilient sleeve.When resilient sleeve is two, two resilient sleeves outer can be enclosed in rotary shaft 221,
It can be enclosed on outside in rotary shaft 221 with one, another is located at the opening position of the axis of corresponding rotation axle 221 in frame 222.

One end of set 31 is connected with connect cover 2221.Spacer pin 32 is fixedly connected on housing 1, and the insertion of spacer pin 32 coordinates in the first bullet
Property set 31 in.Thus, spacer pin 32 defines the direction of motion of the first resilient sleeve 31 to a certain extent, avoids compressor
100 rock causes the first resilient sleeve 31 to misplace so that the first resilient sleeve 31 occurs from the phenomenon for the cushioning effect that recurs.
More specifically, as shown in figure 4, connect cover 2221 is provided with the first assembling pipe 2222, the overcoat of the first resilient sleeve 31 is consolidated
It is scheduled on the first assembling pipe 2222.It is understood that if the first resilient sleeve 31 is only only against in connect cover 2221, due to first
Resilient sleeve 31 is not fixedly connected with the connection of spacer pin 32, and the cushioning effect that now the first resilient sleeve 31 can play more has
Limit.Thus, not only the first resilient sleeve 31 can reduce the vibration of rotary shaft 221 in the axial direction, and the first resilient sleeve 31 coordinates
Spacer pin 32 can also reduce rocking diametrically.
Alternatively, the axis of spacer pin 32 and the axis of rotary shaft 221 coincide.Thus, spacer pin 32 coordinates the first bullet
Property set 31 circumference all directions on spacing amplitudes it is identical.
Certainly, multiple spacer pins 32 can also be set on housing 1, multiple first assembling pipes are set in connect cover 2221
2222, so as to increase shock-proof effect equipped with multiple first resilient sleeves 31 between housing 1 and connect cover 2221.
Alternatively, spacer pin 32 is welded to connect on housing 1.
In certain embodiments, as shown in Fig. 1, Fig. 3-Fig. 4, the second position limitation protection component 4 includes the second assembling He of pipe 42
Second resilient sleeve 41, the second assembling pipe 42 are fixed on housing 1.One end inner sleeve of second resilient sleeve 41 is fixed on the second assembling pipe
On 42, and the end of rotary shaft 221 is extend into the second resilient sleeve 41.This structure can not only limit the radial direction of rotary shaft 221
Amplitude range, and mounting structure is very simple.
Specifically, the second assembling pipe 42 can be straight tube, and the second assembling pipe 42 is welded to connect on housing 1.
Alternatively, the axis of the second assembling pipe 42 and the axis of rotary shaft 221 coincide, and such resilient sleeve 41 is in circumference
To equal to the spacing amplitude of rotary shaft 221 on direction.
More specifically, the bottom of rotary shaft 221 is pump oil axle, it is enclosed on outside the second assembling pipe 42 on pump oil axle to limit pump oil
The radial extent scope of axle, so as to limit the radial extent scope of whole rotary shaft 221.
