Abstract
The utility model relates to a full metal self locking anti-loose nut with a cover, comprising a nut body, a friction ring sheet, a nut cover cap, etc. The friction ring sheet and the nut cover cap are inserted to the upper end of the nut body. Two symmetrical notches are opened in the inner ring of the friction ring sheet. When the screw bolt is screwed, one part of the friction ring sheet can be inserted along screw threads, generating a certain elastic deformation to achieve the locking anti-loosing purpose. The utility model has the advantages of simple technique and structure, material saving and low cost, and is an ideal substitute of the GB923-76 cap type nut.
Description
The utility model belongs to fastener areas, is a kind of anti-loosing cover-shaped nut.
The existing acorn nut GB923-76 of China exists some following shortcomings: nut will pass through cutting, and raw materials consumption is big, the cost height.This nut does not have locking functions, and because of structural reason, can not install other effective locking devices additional.As cotter pin etc., so when this nut is used in the equipment of operation, need the running check nut whether loosening.
The purpose of this utility model is that to propose a kind of production technology simple, the material saving, and cost is low and the acorn nut of self-locking anti-loosing effect function arranged.
The purpose of this utility model is to realize like this, the nut of forming by nut body, friction ring plate, nut cover cap, a groove that can embed friction ring plate, cover cap is arranged in the nut body upper end, the friction ring plate is a sheet metal, the inner ring of ring plate has the recess of two symmetries, and the symmetrical parting face of cover cap is the hemisphere type case of " Ω " shape.
Accompanying drawing and drawing explanation:
Fig. 1 is plan view of the present utility model and partial sectional view;
Fig. 2 is the schematic representation of the utility model friction ring plate;
Fig. 3 is embodiment's schematic representation of the present utility model.
(1)---nut body; (2)---the friction ring plate;
(3)---screw rod; (4)---the nut cover cap.
Below in conjunction with embodiment, the utility model is further described: be a groove that can embed friction ring plate (2), nut cover cap (4) in the upper end of nut body (1), the limit of groove after embedding ring plate and cover cap by punching press, inwardly extruding is fixed ring plate and cover cap, and friction ring plate (2) is to be stamped to form with tool carbon steel or stainless steel sheets.Ring plate inner ring symmetry has two recesses, and nut cover cap (4) is the hemisphere that is stamped to form with steel plate or corrosion resistant plate.Its symmetrical section be shaped as " Ω " shape.The projection and the screw thread correspondence of friction ring plate inner ring, when being screwed into screw rod (3), friction ring plate (2) part sticks into screw flight, and produces certain elastic deformation, thereby reaches the purpose of locking self-locking.
It is low to the utlity model has cost, and manufacturing process is simple, nut is used and loosening under shock conditions.Be applicable to agricultural machinery, automobile, textile manufacturing machine etc.
Claims (1)
1, full-metallic band cover self-locking inserts lock nut is by nut body, friction ring plate, nut cover cap are formed, it is characterized in that there is a groove that can embed friction ring plate, cover cap the nut body upper end, the friction ring plate is a metal ring thin slice, the inner ring of ring plate has the recess of two symmetries, the symmetrical parting face of cover cap be "
" the hemisphere type over body case of shape.
