Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As first aspect of the present utility model, provide a kind of slide plate.As shown in Figure 2, slide plate comprises body, body have connect in turn front-end face 10, upper-end surface 20, breech face 30 and lower end surface 40, and breech face 30 is the end face abutted against with spring 50, body also has flexible slot 60, the notch 61 of flexible slot 60 is opened on breech face 30, and flexible slot 60 departs from the central plane 70 of body and near the side at place, upper-end surface 20, central plane 70 is the plane at 1/2nd places between upper-end surface 20 and lower end surface 40.Owing to being provided with flexible slot 60, thus the tail end top of body is made to have certain amount of deformation, when rubbing with upper flange under the effect of body in disturbing moment, flexible slot 60 can play the effect of plastic deformation, thus the frictional force reduced between slide plate and upper flange, and then the abrasion condition improved between slide plate and upper flange, and effectively improve the stuck situation of slide plate.
In preferred implementation as shown in Figure 2, breech face 30 has knuckle 80 with the jointing place of upper-end surface 20.Owing to there is knuckle 80 at breech face 30 and the jointing place of upper-end surface 20, thus when making the tail end top of body and upper flange produce under the effect of slide plate in disturbing moment to rub, knuckle 80 can ensure that body tangentially contacts with upper flange, thus avoids the problem of the serious wear that may cause because of wedge angle contact or face contact.
Preferably, the thickness direction of the through body of flexible slot 60 is arranged.Because the thickness direction of the through body of flexible slot 60 is arranged, thus further reduce the structural strength of body at flexible slot 60 place, make flexible slot 60 place when stressed, the tail end top of body more yielding, thus improve the wear-resisting reliability of slide plate.
Should meet between the overall dimensions L2 stretching in cylinder body of the first distance L1 between the bottom land 62 of the flexible slot 60 in the utility model and front-end face 10 and body: L1 >=(L2+1mm) (please refer to Fig. 2).In order to ensure functional reliability and the sealing reliability of slide plate, thus the size of the first distance L1 can not arrange long, otherwise can the problems such as coolant leakage be caused.Through inventor's research, when meeting L1 >=(L2+1mm) between the overall dimensions L2 stretching in cylinder body of the first distance L1 and body, the sealing reliability of slide plate can be ensured.
Preferably, the direction of distance along notch 61 to bottom land 62 between be oppositely arranged two cell walls of flexible slot 60 reduces gradually.Area due to notch 61 is greater than the area of bottom land 62, thus makes flexible slot 60 have the feature of easily processing, thus improves the production reliability of slide plate.Certainly, flexible slot 60 also can be that bottom land 62 area is greater than notch 61 area.
Flexible slot 60 in the utility model is rectangle groove, V-shaped groove, dovetail groove or arc surfaced groove.Preferably, when flexible slot 60 is arc surfaced grooves, flexible slot 60 can be set to semi-circular groove further.
In preferred implementation as shown in Figure 2, the first cell wall 63 and the upper-end surface 20 of flexible slot 60 are obliquely installed, and distance between the first cell wall 63 and upper-end surface 20 increases gradually along the direction of breech face 30 end face 10 forward.Because the direction of the distance between the first cell wall 63 and upper-end surface 20 along breech face 30 end face 10 forward increases gradually, thus make slide plate less the closer to the position structural strength of breech face 30 and upper-end surface 20, this is in be subject to frictional force to make more yielding, thus effectively improves the abrasion condition of slide plate and upper flange.Preferably, the second cell wall 64 of flexible slot 60 be arranged in parallel with upper-end surface 20.Certainly, the second cell wall 64 of flexible slot 60 also can be obliquely installed with upper-end surface 20.
In preferred implementation as shown in Figure 2, the first width H1 of the bottom land 62 of flexible slot 60, the second width H2 of notch 61 and the first cell wall 63 should meet between the 3rd width H3 between one end of notch 61 and upper-end surface 20: the relation of 0<H1< (H2+H3).
Preferably, the fillet radius R of knuckle 80 and the 3rd width H3 needs elasticity size needed for the reality of different slide plate and determines further.
Body in the utility model also has the location indentations 90 for mounting spring 50, and the opening of location indentations 90 is opened on breech face 30, and location indentations 90 departs from the central plane 70 of body and the side at close place, lower end surface 40.Depart from the central plane 70 of body due to location indentations 90 and near the side at place, lower end surface 40, thus can effectively reduce disturbing moment, thus improve the degree of wear of slide plate and upper lower flange.
In preferred implementation as shown in Figure 2, should meet between the overall dimensions L2 stretching in cylinder body of the second distance L3 between the bottom of location indentations 90 and front-end face 10 and body: L3 >=(L2+1mm).In order to ensure the sealability of slide plate, avoid coolant leakage, thus second distance L3 should not arrange excessive, studies through inventor, when meeting L3 >=(L2+1mm) between the overall dimensions L2 stretching in cylinder body of second distance L3 and body, the sealing reliability of slide plate can be ensured.
It should be noted that, the unit of L1, L2, L3 is millimeter.
In the preferred implementation that another is not shown, the afterbody upper end of body can also be set to plane of inclination, namely upper-end surface 20 comprises two sections, first paragraph and the lower end surface 40 of close front-end face 10 be arranged in parallel, be obliquely installed near the second segment of breech face 30 and lower end surface 40, and distance between the second segment of upper-end surface 20 and lower end surface 40 increases gradually along the direction of breech face 30 end face 10 forward.Because the afterbody upper end of body is set to plane of inclination, thus the gap between the afterbody upper end of body and upper flange is added, thus make body when producing disturbing moment, the afterbody upper end of body and upper flange are worn and torn because gap is slightly large and reduces, and then improve the operational safety of slide plate.
As second aspect of the present utility model, provide a kind of compressor.Compressor comprises slide plate, and slide plate is above-mentioned slide plate.Owing to reducing the wear intensity between slide plate and upper flange, thus effectively avoid coolant leakage, improve the air-breathing saturation ratio of compressor, and reduce the power consumption of system, thus improve the compression performance of compressor.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
