Abstract
The utility model discloses a fixing structure and bolt for an air conditioner and a compressor thereof. The bolt comprises a base and a polished rod, wherein the polished rod is connected with the back surface of the base; the periphery of the polished rod is provided with an annular lug boss; and the lug boss is connected with the base. When the bolt is matched with a damping washer, an upper fit clearance is formed between the polished rod and the inner hole wall of the damping washer, a lower fit clearance is formed between the lug boss and the inner hole wall of the damping washer, and the width of the upper fit clearance is greater than that of the lower fit clearance, i.e. the damping washer forms a tumbler-like state by using the lug boss at the center. The vibrations of the compressor are beneficial to the up-and-down tensile compression deformation of the damping washer so as to buffer and absorb energy generated by the vibrations in the perpendicular direction, and beneficial to the bending deflection and torsional deformation of the damping washer to absorb energy generated by circumferential vibrations and tangential vibrations of the compressor, thereby effectively lowering the noise and vibrations.
Description
Technical field
The utility model relates to a kind of fixed block, particularly relates to a kind of air-conditioning and fixing structure of compressor thereof and bolt.
Background technique
Like Fig. 1 and shown in Figure 2; It has illustrated the cooperate figure of existing technology bolt with damping washer; The matching gap of bolt and damping washer inner hole wall is big, and like this, air-conditioning outer machine is when doing drop test and test with outer machine stochastic vibration; The compressor holding down bolt is prone to occur bending and deformation, thereby makes compressor in air-conditioning, be in a kind of tendency state.When the inclination situation is serious, can see because the inclination or the displacement of compressor cause its inner pipeline that distortion or the like has also taken place.Above-mentioned problem on deformation can cause that the air-conditioning vibration noise is big, and problems such as pipeline cracking booster have a strong impact on air-conditioning quality and reliability.
In addition; When air-conditioning outer machine stopped in transportation process or crosses obstacle, under the effect of inertial force, the compressor in the air-conditioning can continue to move forward; At this moment the compressor base plate certainly will be given one on bolt top, the location directed force F of direction (as shown in Figure 5) to the right through damping washer top; Under the effect of this directed force F, if the polished rod strength deficiency is easy to occur bending and deformation; Thereby make compressor in air-conditioning, be in heeling condition, suction, the outlet pipe of corresponding compressor also can deform.If this situation continues to occur repeatedly, be easy to cause several consequences: one, the holding down bolt distortion is serious, causes the anomalous of air conditioner noise and vibration big; Two, pipeline is tired or split pipe, causes the air-conditioning reliability decrease, fault increases etc. after sale.
The model utility content
The purpose of the utility model provides a kind of air-conditioning and fixing structure of compressor and bolt; It can overcome the defective of existing technology; Can prevent that air-conditioning is in drop test, stochastic vibration experiment and transportation process; The phenomenon that bolt occurs bending and deformation takes place, and improves problems such as the air-conditioning noise that causes because of the bolt distortion is big, pipeline cracking booster.
The purpose of the utility model is achieved in that
A kind of bolt, it includes: base and polished rod, said polished rod is connected with the back side of said base, and the periphery of said polished rod is provided with the boss of annular, and said boss is connected with said base.
Among embodiment, the transitional surface between said boss and the said polished rod is cambered surface or inclined-plane therein.
Among embodiment, the radius of said cambered surface is 1-3mm therein, and the inclination on said inclined-plane is the 30-70 degree.
Among embodiment, the external diameter of said boss is than the big 1-6mm of external diameter of said polished rod therein.
Among embodiment, the height of said boss is 8-15mm therein.
A kind of fixing structure of compressor; It includes: damping washer reaches as above each described bolt; Said bolt passes said damping washer and installation board of compressor; Form between said polished rod and the said damping washer inner hole wall and go up matching gap, form matching gap down between said boss and the said damping washer inner hole wall, the said matching gap width of going up is greater than the said width of matching gap down.
Among embodiment, the said width of matching gap down is 0.1-0.5mm therein.
Among embodiment, the said width of going up matching gap is 0.5-1mm therein.
A kind of air-conditioning, it includes above each described fixing structure of compressor.
The utility model compared with prior art has following beneficial effect:
The described bolt of the utility model is set up boss through the periphery at said polished rod, makes said polished rod and said boss form staircase structural model.When said bolt cooperates with damping washer; Form between said polished rod and the said damping washer inner hole wall and go up matching gap; Form matching gap down between said boss and the said damping washer inner hole wall; And the said matching gap width of going up is greater than the said width of matching gap down, and promptly said damping washer is formed centrally the state that is similar to tumbler in said boss being.When vibration takes place in compressor; The up-down stretch compressive strain that helps said damping washer absorbs the energy of the vibration generation of Vertical direction with buffering; Simultaneously; Help damping washer bending deflection and torsional deformation,, effectively reduce noise and vibration so that absorb the energy of compressor rotational vibration and tangential vibrations generation.
On the other hand; The said matching gap width of going up is greater than the said width of matching gap down; The vibration that can prevent compressor directly passes to said damping washer by installation board of compressor, is delivered on the installation of air conditioners plate through said polished rod, to reach the effect of damping noise reduction again.
Above-mentioned bolt cooperates with said damping washer; Can prevent that compressor from opening or shutting down moment at transportation process and air-conditioning and moving with said damping washer; Effectively limited the space of compressor with the damping washer slippage; Limited the mobile range and the deformation extent of compressor suction tracheae indirectly, can the better protection pipeline, improve suction, outlet pipe and be out of shape the pipe problem of splitting that causes because of compressor moves.
