Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
As shown in fig. 1-3: the utility model provides an engine sealing gasket, the engine sealing gasket includes annular gasket body 1, be formed with cylinder groove 5 on the gasket body 1, the surface of gasket body 1 is from inside to outside the interval form first draw-in groove 2 and second draw-in groove 3, the surface cooperation of cylinder groove 5 is provided with annular seal ring 4; the upper end and the lower end of the annular sealing ring 4 extend outwards to form annular parts 406 respectively, the outer side surface of the annular part 406 is provided with a first sealing bulge 403 and a second sealing bulge 404 from inside to outside at intervals, the end part of the second sealing bulge 404 far away from the cylinder groove 5 is a free end 405, and the free end 405 is movably clamped in the second clamping groove 3. Be provided with matched with ring packing on this seal gasket's the cylinder groove, ring packing's surface interval is provided with first sealed arch and the sealed arch of second, two sealed archs can play the sealed protection effect of bilayer, and simultaneously, the mobile block of the sealed bellied free end of second takes place the deformation back in the second draw-in groove, the free end can extend in the second draw-in groove, give the certain extension space of sealing washer, make whole sealing washer possess better deformation and extension power, improve its sealed effect.
