Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution:

the utility model provides a have and draw ear gasket for mechanical equipment, includes gasket body 1, is provided with on the lateral wall of gasket body 1 and draws ear 2, draws and has seted up on ear 2 and draw ear hole 3, and installation through-hole 4 has been seted up to the terminal surface center department of gasket body 1, and the bottom of gasket body 1 is provided with expansion ring 5 and the edge that is located installation through-hole 4, has seted up the logical groove 6 of inflation on expansion ring 5.

Furthermore, the pull lugs 2 are perpendicular to the gasket body 1, the circle center of the installation through hole 4 and the circle center of the expansion ring 5 are on the same straight line, at least three expansion through grooves 6 are formed in the expansion ring 5 at equal angles, the expansion ring 5 is of a conical structure, the gasket body 1 is positioned, after the gasket body is placed, connecting bolts are sequentially arranged between objects to be connected to form sealing, when the connecting bolts are connected in the installation holes, outward radial extrusion force for extruding the expansion ring 5 is applied, at the moment, at least three expansion through grooves 6 are formed in the expansion ring 5 at equal angles, the expansion ring 5 is expanded under the action of the conical structure of the expansion ring 5, and then the expansion ring is precisely attached to the installation holes, and sealing and fixing are achieved;

further, gasket body 1, draw ear 2 and expansion ring 5 all adopt rubber, gasket body 1, draw ear 2 and expansion ring 5 to integrated into one piece structure, draw ear 2 to set up the center department at 1 lateral wall of gasket body, and the thickness that draws ear 2 is the half of 1 thickness of gasket body, thereby utilize physical properties, elasticity, draw ear 2 relative resume initial position, thereby the staff can hold and draw ear 2 through hand or instrument, thereby the convenience is to 1 dismouting of gasket body. The specific implementation case is as follows:
