Specific embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.

It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can To be combined with each other.

In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower, top, bottom " is usually Be for direction shown in the drawings either for it is vertical, vertically or on gravity direction for each component mutual alignment Relationship description word.

The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

The utility model provides a kind of compressor 100, and as shown in Figures 1 to 7, which includes inside and outside nesting The shell wall 2 and inner wall 3 of setting.Wherein, the inner circumferential face interval of the outer peripheral surface of inner wall 3 and shell wall 2 is arranged, shell wall 2 It is equipped with inner tube through hole 21 and fixes the external tapping pipe 8 stretched out from the surrounding wall of the inner tube through hole 21, it is solid on inner wall 3 Surely it is extended with pump housing air inlet tube 9, which is pierced by from inner tube through hole 21 and is set in external tapping pipe 8.This Outside, circumferential vibration isolation element 4, external tapping pipe 8 are installed between the outer tube wall of pump housing air inlet tube 9 and the inner tubal wall of external tapping pipe 8 Outer end be connected with positive stops, in the outer end face of circumferential vibration isolation element 4 is crimped with positive stops and inner face presses on It is tightly connected on the surrounding wall of pipe through hole 21 with being formed.

In the course of work of compressor 100, between pump housing air inlet tube 9 and shell wall 2 can due to the pump housing vibration and In the presence of the risk mutually collided.But it is equipped between the outer tube wall due to pump housing air inlet tube 9 and the inner tubal wall of external tapping pipe 8 circumferential The amplitude of vibration isolation element 4, pump housing air inlet tube 9 can be gradually reduced under the buffer function of the circumferential direction vibration isolation element 4, i.e., circumferentially Vibration isolation element 4 can obstruct the rigid contact between pump housing air inlet tube 9 and shell wall 2, to obstruct vibration in compressor In transmitting and avoid the vibration aggravation of compressor complete machine, therefore the operating noise of compressor is effectively reduced, user Usage experience also substantially improved.On the other hand, the flexible connection between pump housing air inlet tube 9 and shell wall 2 can have Effect delays structural wear, to improve the durability and reliability of compressor.

Further, since the outer end face of circumferential vibration isolation element 4 is crimped with positive stops and inner face presses on inner tube and runs through On the surrounding wall in hole 21, the air-tightness between inner tube through hole 21 and pump housing air inlet tube 9 effectively improves, to reduce gas The loss of state refrigerant, it is ensured that the normal operation of compressor.

In order to keep the flexible connection between pump housing air inlet tube 9 and shell wall 2, it need to guarantee the dress of circumferential vibration isolation element 4 With stabilization.Hereby, above-mentioned positive stops are equipped in the compressor 100 of the utility model, which can will be all It is pressed in vibration isolation element 4 between the outer tube wall of pump housing air inlet tube 9 and the inner tubal wall of external tapping pipe 8, to ensure that the pump housing Flexible connection is remained between air inlet tube 9 and shell wall 2.

In a kind of preferred embodiment of the utility model, as shown in Figure 1 to Figure 3, positive stops may be configured as pressing Tight nut 5, is wherein connected through a screw thread between the clamp nut 5 and external tapping pipe 8.It, can be right when clamp nut 5 screws Circumferential vibration isolation element 4 applies pressing force, so that it is guaranteed that the mounting stability of circumferential vibration isolation element 4.

In another preferred embodiment of the utility model, positive stops may be configured as being connected to external tapping pipe 8 Outer end edge annular end face pressing plate 6.The annular end face pressing plate 6 can both be fixed in external tapping pipe 8 (as schemed by modes such as welding Shown in 4 and Fig. 5), it may be alternatively provided as being from the outer end of external tapping pipe 8 along the structure (as shown in Figure 6 and Figure 7) integrally stretched out.Together Sample, annular end face pressing plate 6 can apply pressing force to circumferential vibration isolation element 4 to ensure the secured assembly of circumferential vibration isolation element 4.

Specifically, compressor 100 further includes liquid storage device 1, which is equipped with the air inlet pipe of liquid storage device 11 to circulate for refrigerant With air outlet pipe of liquid storage device 12.It, can be in limit stops for the connection being adapted between air outlet pipe of liquid storage device 12 and pump housing air inlet tube 9 Stop part punched out 7 is set in part, and pump housing air inlet tube 9 can be pierced by the stop part punched out 7 and be gone out with connecting liquid storage device at this time Tracheae 12, and the aperture of stop part punched out 7 be not less than inner tube through hole 21 aperture, with prevent pump housing air inlet tube 9 with Rigid collision between the hole wall of stop part punched out 7.

It should be noted that pump housing air inlet tube 9 may include the air inlet pipeline section 91 and interface pipeline section 92 connected from the inside to the outside, Circumferential vibration isolation element 4 is located between the outer tube wall of interface pipeline section 92 and the inner tubal wall of external tapping pipe 8 at this time, air outlet pipe of liquid storage device 12 It is connect with interface pipeline section 92.

Further, since circumferential vibration isolation element 4 is pressed in the outer tube wall of pump housing air inlet tube 9 and the inner tube of external tapping pipe 8 Between wall, therefore the radial thickness of circumferential vibration isolation element 4 is bigger, the outer tube wall of pump housing air inlet tube 9 and the inner tube of external tapping pipe 8 Radial spacing between wall is also bigger, can increase its slow vibration ability by increasing the radial thickness of circumferential vibration isolation element 4 at this time.

Under the premise of improving the slow vibration performance of compressor 100, also need to consider how simultaneously effectively to control slow vibration cost.Cause This, preferably use is easily obtained, reasonable price and rubber material vibration isolation element of good performance are as above-mentioned circumferential vibration isolation Element 4.

Preferred embodiments of the present invention, still, the utility model and unlimited are described in detail in conjunction with attached drawing above Detail in above embodiment can be to the skill of the utility model in the range of the technology design of the utility model Art scheme carries out a variety of simple variants, these simple variants belong to the protection scope of the utility model.

It is further to note that specific technical features described in the above specific embodiments, in not lance It in the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the utility model is to each No further explanation will be given for the possible combination of kind.

In addition, any combination can also be carried out between a variety of different embodiments of the utility model, as long as it is not disobeyed The thought for carrying on the back the utility model, equally should be considered as content disclosed in the utility model.
