Abstract
The utility model discloses an automotive engine cylinder gasket which comprises an upper plate (1), an intermediate plate (2) and a lower plate (3). The intermediate plate (2) is positioned between the upper plate (1) and the lower plate (3). The three plates are fixed together and cylinder through holes (4) are formed in the relative positions on the three plates. A metal buckle plate (5) is arranged between the upper plate (1) and the intermediate plate (2). The metal buckle plate (5) is formed by connecting a plurality of rings which are arranged side by side. The number of the rings is equal to that of the cylinder through holes (4) and the rings are positioned relative to the cylinder through holes (4) respectively. The metal buckle plate arranged between the upper plate and the intermediate plate can ensure the seal property and prevent the water leakage or the air leakage. The automotive engine cylinder gasket has the characteristics of novel design, simple structure, good seal property, long service life, etc., thereby being suitable for large-scale use.
Description
Technical field
The utility model relates to a kind of motor car engine seal element, relates in particular to the automobile engine cylinder pad.
Background technique
Head gasket is the important seal element on the motor car engine, is installed between cylinder body and the cylinder cap, plays sealing, and is air tight to guarantee, oil-proof and water-tight.Traditional automobile engine cylinder pad is generally nonmetal structure, because the head gasket operating conditions is abominable, the nonmetal structure resiliently deformable is bigger, causes that easily cylinder bolt is loosening, causes poorly sealedly, scurries water or gas blowby fault.
The model utility content
The automobile engine cylinder pad that provides a kind of sealability secure is provided technical problem to be solved in the utility model.
The technical solution of the utility model is as follows: a kind of automobile engine cylinder pad, comprise upper plate, middle plate and lower plate, wherein middle plate is between upper plate and lower plate, the three is fixed together, and the relative position the three has the cylinder through hole, and its key is: be provided with Metal pinch plate between described upper plate and middle plate, this Metal pinch plate is made up of the annulus that links to each other side by side, the number of annulus equates with the number of cylinder through hole, and the position of each annulus is corresponding with the cylinder through hole respectively.
In the utility model, the Metal pinch plate of being made up of a plurality of annulus can increase the thickness around the cylinder through hole and improve its intensity, and the head gasket resiliently deformable is little like this, can not cause that cylinder bolt becomes flexible, thereby effectively ensured the sealability of head gasket, avoided scurrying water or gas blowby fault.
Outer rim at above-mentioned Metal pinch plate is distributed with " ∩ " shape buckle ear, corresponding via hole on the plate during each buckle ear passes, and with the bottom surface snapping of middle plate.Above structure had both helped assembling, and it is firm to guarantee again to be connected between Metal pinch plate and the middle plate.
For further proof strength, above-mentioned upper plate, middle plate and lower plate are the sheetmetal structure.
Beneficial effect: the utility model ensures sealability by set up Metal pinch plate between upper plate and middle plate, prevents to scurry water or gas blowby and takes place, have be skillfully constructed, characteristics such as simple in structure, good airproof performance, long service life, be suitable for large-scale promotion and use.

Fig. 2 is the structural representation of Metal pinch plate in the utility model.
Fig. 3 is the A-A cutaway view Amplified image of Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2 and shown in Figure 3, with the little car engine head gasket of the little discharge capacity of four cylinders is example, the utility model is made of parts such as upper plate 1, middle plate 2, lower plate 3 and Metal pinch plates 5, wherein upper plate 1, middle plate 2 and lower plate 3 are the sheetmetal structure, plate 2, Metal pinch plate 5 and upper plate 1 on lower plate 3, superposeing successively, upper plate 1, middle plate 2 and lower plate 3 threes' shape, size adapt, and by rivet together.Relative position upper plate 1, middle plate 2 and lower plate 3 threes offers four equal-sized circular cylinder through holes 4, bolt hole and several water ports and oil throughs, and it is fixed that the shape size of water port and oil through is come according to concrete type.Described Metal pinch plate 5 is made up of four annulus that link to each other side by side, and the position of four annulus is corresponding with four cylinder through holes 4 respectively, and the internal diameter of each annulus is than the slightly larger in diameter of corresponding cylinder through hole 4.Outer rim at described Metal pinch plate 5 is distributed with a plurality of " ∩ " shape buckle ear 6, corresponding via hole on the plate 2 during each buckle ear 6 passes, and with the bottom surface snapping of middle plate 2, make Metal pinch plate 5 be fixed on the plate 2.
Although below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression; as change the number of cylinder through hole; perhaps change Placement between Metal pinch plate and the middle plate etc., such conversion all falls within the protection domain of the present utility model.
Claims (3)
1, a kind of automobile engine cylinder pad, comprise upper plate (1), middle plate (2) and lower plate (3), wherein middle plate (2) is positioned between upper plate (1) and the lower plate (3), the three is fixed together, and the relative position the three has cylinder through hole (4), it is characterized in that: between described upper plate (1) and middle plate (2), be provided with Metal pinch plate (5), this Metal pinch plate (5) is made up of the annulus that links to each other side by side, the number of annulus equates with the number of cylinder through hole (4), and the position of each annulus is corresponding with cylinder through hole (4) respectively.
2, automobile engine cylinder pad according to claim 1 is characterized in that: the outer rim at described Metal pinch plate (5) is distributed with " ∩ " shape buckle ear (6), and each buckle ear (6) passes middle plate (2) and goes up corresponding via hole, and with the bottom surface snapping of middle plate (2).
3, automobile engine cylinder pad according to claim 1 and 2 is characterized in that: described upper plate (1), middle plate (2) and lower plate (3) are the sheetmetal structure.
