Abstract
A kind of piston pad used for automobile air conditioning, including disc-shaped body, this disc-shaped body is provided with first group of screw hole and second group of screw hole, and one end end face of this disc-shaped body is sealing surface, and the other end end face of described disc-shaped body is convexly equipped with salient point.The beneficial effects of the utility model are: 1, can be distinguished the positive and negative of piston pad used for automobile air conditioning by salient point, prevent wrongly installed.2, sealing surface is positioned on one end end face of disc-shaped body, and salient point is positioned on the other end of disc-shaped body, it is only necessary to an end face of polish disc-shaped body, cost-effective.3, the setting of salient point, also can play the role of positioning, it is simple to Fast Installation and processing.
Description
Technical field
This utility model relates to piston element used for automobile air conditioning, particularly relates to a kind of piston pad used for automobile air conditioning.
Background technology
In prior art, piston pad used for automobile air conditioning mainly includes disc-shaped body, and this disc-shaped body is provided with
One group of screw hole and second group of screw hole, first group of screw hole and second group of screw hole be mainly used in piston element other zero
Part fixes, and one end end face of disc-shaped body is used for sealing thus forms sealing surface.In order to reach sealing effectiveness, this sealing surface
Planarity requirements higher.During practical set, owing to the shape difference of two end faces of disc-shaped body is few, hold very much
The most wrongly installed, cause sealing surface can not contact with structure to be sealed, greatly reduce the sealing of piston element used for automobile air conditioning
Energy.If the two ends end face of disc-shaped body all being carried out polish to reach the requirement of flatness, automobile will certainly be improved empty
Call the cost of manufacture of piston pad.
Summary of the invention
There is above-mentioned deficiency in prior art to overcome, this utility model provides a kind of simple and compact for structure, sealing
Effective, be difficult to wrongly installed piston pad used for automobile air conditioning.
The technical scheme in the invention for solving the technical problem is: a kind of piston pad used for automobile air conditioning, including disk
Shape body, this disc-shaped body is provided with first group of screw hole and second group of screw hole, and one end end face of this disc-shaped body is
Sealing surface, the other end end face of described disc-shaped body is convexly equipped with salient point.
Further, the height of described salient point is 0.5mm, and the outline of described salient point is rounded, its a diameter of 2mm.Or,
The outline of described salient point is square, and its length of side is 2mm.The shape of salient point can also be other shapes such as rectangle, triangle
Shape.
Further, the flatness of described sealing surface is 0.15mm, good sealing effect.
Further, the number of described first group of screw hole and second group of screw hole is 2,2 described first group of screws
Hole and 2 described second group of screw holes intersect and are distributed on same circumference, fixing reliable.
Further, described salient point is positioned on same circumference with described first group of screw hole and the second screw hole, rationally distributed.
The beneficial effects of the utility model are: 1, can be distinguished the positive and negative of piston pad used for automobile air conditioning by salient point,
The end face without salient point is sealing surface, prevents wrongly installed.2, sealing surface is positioned on one end end face of disc-shaped body, and convex
Point is positioned on the other end of disc-shaped body, because of the setting of salient point, can know which end face is sealing surface clearly, it is not necessary to
Both ends of the surface are all processed, it is only necessary to polish does not have an end face of salient point, cost-effective.3, the setting of salient point,
Also can play the role of positioning, it is simple to Fast Installation and processing.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1, Fig. 2, a kind of piston pad used for automobile air conditioning, including disc-shaped body 1, this disc-shaped body is provided with
First group of screw hole 2 and second group of screw hole 3, one end end face of this disc-shaped body is sealing surface 4, described disc-shaped body
Salient point 5 it is convexly equipped with on other end end face.The positive and negative of piston pad used for automobile air conditioning can be distinguished by salient point 5, not there is salient point
End face be sealing surface, prevent wrongly installed.Sealing surface 4 is positioned on one end end face of disc-shaped body 1, and salient point 5 is positioned at circle
On the other end of discshaped body 1, because of the setting of salient point, can know which end face is sealing surface clearly, it is not necessary to both ends of the surface
All it is processed, it is only necessary to polish does not have an end face of salient point, cost-effective.The setting of salient point 5, it is fixed also can to rise
Position effect, it is simple to Fast Installation and processing.
The height of described salient point 5 is 0.5mm, and the outline of described salient point 5 is rounded, its a diameter of 2mm.Or, described
The outline of salient point 5 is square, and its length of side is 2mm.The shape of salient point 5 can also be other shapes such as rectangle, triangle.
The flatness of described sealing surface 4 is 0.15mm, good sealing effect.
The number of described first group of screw hole 2 and second group of screw hole 3 is 2,2 described first group of screw holes 2 and 2
Individual described second group of screw hole 3 intersects and is distributed on same circumference, fixing reliable.
Described salient point 5 is positioned on same circumference with described first group of screw hole 2 and the second screw hole 3, rationally distributed.
