Abstract
The utility model relates to a shockproof gasket for an air conditioner foot. The gasket is annular, a center hole perpendicularly turns outwardly, an internal diameter is matched with the external diameter of a screw of the air conditioner foot, and the gasket is arranged between an air conditioner base plate and the rubber foot and is sleeved on the foot screw. Compared with the prior art, the shockproof gasket can disperse the vibration stress received by the foot, and can reduce the stress of a foot soldering point.
Description
Technical field
The utility model relates to field of Refrigeration and Air-conditioning such as air-conditioner, refrigerator, is specifically related to a kind of air-conditioning footing earthquake washer.
Background technology
Air-conditioning in the road transport process since the road surface jolt and the startup of lorry brake is turned and is caused the vibration of compressor of air conditioner, vibration causes the footing screw rod to tear the air-conditioning base plate for a long time.Mainly be that masterpiece is used in rubber footing top, is delivered to bond pad locations by moment, damages because of the X, the Y direction power that produce in the vibration processes, this power is subjected to the influence of following factor:
(1) compressor weight: weight is big more, and under identical acceleration excitation, Fx, Fy are big more, and be big more to the opplied moment of footing screw rod.
(2) Rubber foot height: low highly more, the arm of force of footing screw rod is short more, and the moment at solder joint place is more little; So the possibility that triangle footing, frequency sweep test do not pass through is lower.
(3) test acceleration amplitude parameter: the exciting acceleration is big more, and Fx, Fy are big more.
(4) when test frequency is in the intrinsic frequency of system, (pipeline+compressor) system produces exciting, and X, Y increase to acceleration, and Fx, Fy strengthen.
(5) increase constraint to compressor: perhaps 0.5～3 and C1 gap as Fig. 1 reduces, perhaps append hook and retrain on compressor top, like this when carrying out frequency sweep test, compressor X, Y to the play amplitude reduce.
(6) rigidity of Rubber foot: influence the resonance of pipeline.
(7) reduce the rigidity of footing screw rod, like this during vibration of compressor,, alleviate the impact of butt welding point by self damping of screw rod.But this prerequisite is that the rigidity Kd/Ks of suction and discharge tube connector system is higher relatively, otherwise the compressor amplitude of fluctuation is bigger, and the solder joint of footing screw rod is out of question, but pipeline gives shake disconnected.
(8) increase the weld strength of footing screw rod, as append solder joint etc.
(9) in present footing screw rod and this Welding Structure of base plate, be that the bar hardboard is soft, final solder joint is torn plate.If increase the rigidity of plate and strengthen solder joint simultaneously, can produce effect.
(10) employing is shown in Figure 2, inserts a sleeve pipe in Rubber foot, and so in fact sleeve pipe bottom and screw rod clamping simultaneously base plate is equivalent to increase the constraint area; May be effectively.If but plate is soft partially, whole plate respective area may be torn.
(11) rigidity of increase Rubber foot neck, (be confined to size, the change remaining is little, and the difficult assessment of effect)
(12) adjust pipe-line system, increase the rigidity Kd/Ks of suction and discharge tube connector system, the whipping of physical constraint compressor top X, Y direction.Because the outdoor machine system of Gree is bigger at present, consider piping vibration or the like when adopting softer copper pipe again, it is bigger to adjust difficulty.
Summary of the invention
The purpose of this utility model is exactly to provide the footing screw rod that causes because jolting vibration in a kind of simple and effective solution air-conditioning transportation to tear the air-conditioning footing earthquake washer of the problem of base plate for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of air-conditioning footing earthquake washer, it is characterized in that, this packing ring is circular, centre bore vertically turns up, the external diameter of internal diameter and air-conditioning footing screw rod is complementary, described packing ring is located between air-conditioning base plate and the rubber footing, is enclosed within on the footing screw rod.
The interior ring centre bore of described packing ring vertically turns up and exceeds outer shroud 5～20mm.
The material of described packing ring comprises plastics or metal.
The gap that 0.5～2mm is arranged between the external diameter of the internal diameter of described packing ring and air-conditioning footing screw rod.
Compared with prior art, the utility model plays the effect that disperses footing to be subjected to vibration stress by design air-conditioning footing earthquake washer, reduced the stress of footing pad, thereby made it in the frequency sweep test of simulation road conditions, pass through fully, the phenomenon of footing fracture has no longer taken place.The cost of Zeng Jiaing is also very low simultaneously, estimates that every air-conditioning need increase by 0.5 yuan, compares with the cost of air-conditioning base plate attenuate and wants cheap a lot.
Description of drawings
Fig. 1 is the structural representation of existing packing ring;
Fig. 2 is the another kind of structural representation of existing packing ring;
Fig. 3 is the schematic diagram that does not use the compressor footing screw rod of packing ring;
Fig. 4 is the schematic diagram of the compressor footing screw rod of use the utility model packing ring;
Fig. 5 is a perspective view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As Fig. 1～shown in Figure 5, a kind of air-conditioning footing earthquake washer, this earthquake washer 1 centre bore vertically turns up, and internal diameter will have certain clearance to cooperate with the external diameter of air-conditioning footing screw rod 2, need be installed between air-conditioning base plate 3 and the rubber footing 4, be enclosed within (see figure 4) on the footing screw rod 2.When shipping,, also have in addition that lorry starts, the anxious tangential vibrations (frequency is less relatively) of stopping, causing when turning because jolting of causing of the unevenness on ground caused air-conditioning inner compressor up-down vibration (main mode of vibration).So last road conditions simulated test mainly is based on vibration up and down.
Do not use the situation of earthquake washer to see Fig. 3, it is F1 that compressor is given the tangential force of footing, is H apart from the pad height, thus this moment compressor to give the moment of torsion of footing be F1H, this power will all be conducted on the F2; Fig. 4 has used earthquake washer like this, and at first F1 conducts power to F3, is conducted to F2 ' and F4 by F3 then again, and wherein main power is born by F4, and the power that F2 ' is subjected to will be far smaller than F2.This shows that the disconnected probability of footing screw rod shake will reduce greatly.
Rili Electric Appliance Co Ltd, Shanghai is installed to earthquake washer on 72 air conditioners of Gree when doing frequency sweep test, and frequency sweep test is done in the simulate vibration.
The frequency sweep condition: frequency sweep comes and goes scanning again from 100Hz to 5Hz from 5Hz to 100Hz, acceleration is 0.75g, and scan pattern is a log scan, and sweep speed is 1.0octave/min, and the unidirectional 4.322min that wants comes and goes scanning 6 times altogether.Test period is 51.864min.The resonance point of finding out air-conditioner from the frequency sweep process is the frequency of air-conditioner amplitude maximum.Fixed frequency is tested 21300 times under this frequency then, and test period is 32.273min.This test resonant frequency is 11Hz, whole test consuming time 1 hour 24 minutes.
Frequency sweep result: packing ring and base plate contact-making surface have obvious impression, illustrate that packing ring is stressed to have played effect; Footing solder joint place does not have obvious crackle, so judge success of the test.
