Specific embodiment
The utility model embodiment provides a kind of pre- elastic gasket, and solving current gasket is all monolithic construction,
It has a single function, the forewarning function of screw or nut loosening tension cannot be played, for big for vibration and frequent automobile, such as
In auto repair, the power that nut is tightened is not big enough, be easy to cause nut loosening, increases security risk；The power tightened is excessive, holds
The technical issues of easily causing nut stripped thread or fracture, increasing maintenance difficulty.
It, below will knot to enable the purpose of utility model, feature, advantage of the utility model more obvious and understandable
The attached drawing in the utility model embodiment is closed, the technical scheme in the utility model embodiment is clearly and completely described,
Obviously, the embodiments described below are only the utility model a part of the embodiment, and not all embodiment.Based on this reality
It is obtained by those of ordinary skill in the art without making creative efforts all other with the embodiment in novel
Embodiment is fallen within the protection scope of the utility model.
Fig. 1 and Fig. 2 are please referred to, the utility model embodiment provides a kind of one embodiment of pre- elastic gasket, comprising:
