Abstract
The invention discloses a self-locking screw cap which can effectively prevent loose. An internally edge curled boss 2 is arranged at the top of the screw cap 1; a plastic locking part 3 is arranged inside the internally edge curled boss 2; the plastic locking part 3 is embedded inside the internally edge curled boss 2; the internally edge curled boss 2 is in a hexagon shape; the plastic locking part 3 is in a hexagon shape. Rotation does not occur however the quality is when a hexagonal outer edge of the plastic locking piece 3 is embedded into the hexagonal edge curled boss 2, , so that requirements for machining technology are low, the machining efficiency is improved, the machining costs are reduced, and quality is easily guaranteed absolutely.
Description
Technical field
The invention belongs to fastening connection piece, particularly a kind ofly can effectively prevent loosening screw cap.
Background technique
The anti-loosening key technology scheme of establishing on " self-locking nut " of the patent No. 982302509 is " interior crimping garden ring boss studs with plastic latch collar ".The effect that " plastic latch collar " reaches anti-loosened screw must possess two conditions, and the one, while manufacture, to guarantee that " plastic latch collar " and " interior crimping garden ring boss " guarantee the quality of stationary fit; The 2nd, while use, can guarantee that screw can be screwed in " plastic latch collar " smoothly, actual being summed up is exactly a problem, and that is exactly that " plastic latch collar " to become all-in-one-piece words with " interior crimping garden ring boss " be with regard to desirable state.Because this technological scheme is that " plastic latch collar " is the accessory of different nature that two circles (inner circle and cylindrical) are connected with " interior crimping garden ring boss ", therefore work in-process need to have higher requirement to the quality coordinating, not only increase processing cost, also the underproof product of unavoidable appearance, has affected and has used and anti-loosening assurance.
Summary of the invention
For the problem of above-mentioned existence, the object of the invention provides a kind of processing technology simple, the self-locking screw cap that quality easily guarantees.
Technological scheme of the present invention is, a kind of self-locking screw cap, and screw cap body is established interior crimping boss 2 on 1 top, in interior crimping boss 2, establishes plastics locking element 3, and plastics locking element 3 is set in interior crimping boss 2, and interior crimping boss 2 is hexagon, and plastics locking element 3 is hexagon.
Good effect of the present invention is, plastics locking element 3 be hexagonal outward edge be bumped into be hexagonal interior crimping boss 2 interior after, the phenomenon how quality of processing can not rotate, therefore relatively require low to processing technology, not only can improve work efficiency and cut down finished cost, also easily absolute ensuring the quality of products.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Accompanying drawing is schematic diagram of the present invention.
In figure, 1, screw cap body, 2, interior crimping boss, 3, plastics locking element, 4, the bolt diameter that adapts
Concrete mode of execution
With reference to accompanying drawing, it is hexagonal interior crimping boss 2 that inward flange is processed at screw cap body 1 top, and plastics locking element 3 outward edges are processed into the hexagon matching with interior crimping boss 2, and interior crimping boss 2 is a little more than plastics locking element 3.The diameter 4 that lock bolt adapts is established at plastics locking element 3 centers, and plastics locking element 3 is bumped into after interior crimping boss 2, and the interior crimping boss 2 a little more than plastics locking element 3 is encased to plastics locking element 3, and interior crimping boss 2 is become one with plastics locking element 3.
Claims (1)
1. a self-locking screw cap, screw cap body is established interior crimping boss 2 on 1 top, in interior crimping boss 2, establishes plastics locking element 3, and plastics locking element 3 is set in interior crimping boss 2, it is characterized in that, and interior crimping boss 2 is hexagon, and plastics locking element 3 is hexagon.
