Anti-roll sealing gasket structure

Technical Field

The utility model relates to a sealed technical field that fills up especially relates to a sealed pad structure of preventing heeling.

Background

At present, a large number of sealing gaskets are applied to the hood cover of an automobile engine and mainly used for sealing oil in the engine. Because the longitudinal section of the sealing gasket is long-strip, the sealing gasket is installed in a standing mode. Referring to fig. 1, a conventional engine gasket includes a longitudinal cushion portion 1 and a lateral cushion portion 2 disposed at an upper end of the longitudinal cushion portion 1. When the engine sealing gasket is used, the longitudinal cushion part 1 is inserted into a sealing groove of an engine cylinder body, and the transverse cushion part 2 is attached to the engine hood so as to seal and force the joint of the engine hood and the cylinder body through the engine sealing gasket.

Because the whole structure of the sealing gasket is in a long strip shape, when the sealing gasket is used, the sealing gasket is pressed to seriously incline when being installed, so that the compression ratio deviates from the design value, the reliability is reduced, the service life is shortened, and even the short-mileage oil leakage phenomenon is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prevent sealed pad structure of heeling compares and has more excellent ability of preventing heeling in current sealed pad.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a sealed pad structure of preventing heeling, includes indulges the pad portion and sets up the horizontal pad portion in indulging the pad portion upper end, the both sides of indulging the pad portion are provided with a plurality of length direction respectively and indulge the brace rod that the pad portion length direction set up, it has the location tooth to indulge pad portion both sides and be provided with the equipartition along its length direction, the location tooth is crossing with the brace rod.

According to the technical scheme, the positioning teeth are distributed on the whole sealing gasket at intervals and are in interference fit with the sealing groove of the engine cylinder body so as to ensure that the mounting position of the sealing gasket is fixed; the supporting ribs are continuous on two sides of the middle of the sealing gasket and are in clearance fit with the sealing groove of the engine cylinder body, and when the sealing gasket is about to roll, the supporting ribs play a role in supporting and preventing the roll, so that the sealing gasket has good roll prevention capability.

Preferably, the upper part of the transverse pad part is provided with a sealing bulge.

Through above-mentioned technical scheme, be provided with sealed protruding through the upper portion at horizontal pad portion, and then when installing engine bonnet on the engine cylinder body, through compressing sealed protruding, sealed protruding formation secondary seal to further strengthen the sealed effect of junction.

Preferably, the number of the sealing bulges is two, and the two sealing bulges are symmetrically arranged around the central plane of the longitudinal part; an adsorption groove is formed between the two sealing bulges.

Through above-mentioned technical scheme, form the adsorption tank between two archs, and then under the extrusion of engine bonnet and engine cylinder body, extrude the air in the adsorption tank and discharge, and then utilize the negative pressure effect, make sealed pad can be good with the engine bonnet laminating sealed.

Preferably, adjacent side walls of the sealing protrusion are obliquely intersected, and the included angle between the adjacent side walls is an obtuse angle.

Through above-mentioned technical scheme, the slope of the protruding adjacent lateral wall of sealing is crossing to the two contained angles are the obtuse angle, and then when engine bonnet extrudeed sealed protruding, sealed protruding laminating that can be better is on engine bonnet's contact surface.

Preferably, the cross-sectional area of the longitudinal pad portion is gradually reduced from top to bottom.

Through above-mentioned technical scheme, the cross sectional area from the top down of indulging the pad portion reduces gradually to make things convenient for the staff to insert indulging the pad portion in the seal groove of engine cylinder block.

Preferably, the cross-sectional shape of the support rib is a triangle which is inclined downwards and protrudes.

Through above-mentioned technical scheme, the cross sectional shape of brace rod is the convex triangle-shaped of downward sloping, not only conveniently installs sealed the pad on the engine cylinder body, uses the brace rod to have better support anti-dumping ability moreover.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that, as used in the description below, the words "front", "rear", "left", "right", "upper" and "lower" refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer", respectively, refer to directions that are directed away from the geometric center of a particular component.

Example (b):

a structure of a anti-roll packing, referring to FIGS. 2 and 3, includes a vertical mat portion 1 and a horizontal mat portion 2 disposed at an upper end of the vertical mat portion 1. In fig. 3, a indicates an engine block, and B indicates an engine cover. The cross-sectional area of the side pad portion 1 gradually decreases from top to bottom. The two sides of the longitudinal pad part 1 are respectively provided with a plurality of supporting ribs 3 which are arranged along the length direction of the longitudinal pad part 1, and the cross section of each supporting rib 3 is in a triangle shape which is downwards inclined and protruded. The two sides of the longitudinal pad part 1 are uniformly distributed with positioning teeth 4 along the length direction, and the positioning teeth 4 are intersected with the support ribs 3. The upper part of the cross cushion part 2 is provided with a sealing bulge 5. The number of the sealing bulges 5 is two, and the two sealing bulges 5 are symmetrically arranged relative to the central plane of the longitudinal part; an adsorption groove 6 is formed between the two sealing bulges 5.
