Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The embodiments of the present invention will be described in detail with reference to the accompanying drawings:

referring to fig. 2-3 and 8-9, the present invention provides a first embodiment: the utility model provides a dysmorphism cross-section sealing washer, includes sealing washer core 11 and triangle-shaped binding face 12, and sealing washer core 11 is the rectangular cross section structure, and the upper and lower, left and right sides of sealing washer core 11 all is equipped with sealing washer border 13, sealing washer border 13 is the arc segment, is provided with transition arc segment 14 between the adjacent sealing washer border 13, and triangle-shaped binding face 12 sets up in the surface of sealing washer border 13, and the surface of every sealing washer border 13 all is provided with triangle-shaped binding face 12, can satisfy the combination form of multiple parts such as two groups of parts, three groups of parts, four groups of parts, has certain commonality and convenience.

Preferably, the surface of each sealing ring edge 13 includes two triangular binding surfaces 12, and the two triangular binding surfaces 12 are symmetrically arranged on the surface of the sealing ring edge 13, and because the triangular binding surfaces 12 and the wall of the part sealing groove are butted and deformed, the contact surface between the deformed triangular binding surfaces 12 and the wall of the part sealing groove is larger, and the surface of each sealing ring edge 13 is provided with the two triangular binding surfaces 12, so that the sealing effect can be effectively enhanced.
