Description
Technical field
The utility model relates to a kind of retaining element, specifically relate to a kind of plastic screw.
Background technique
Existing automobile-used screw, when the vehicle body sheet metal with band counterbore assembles, plays the role of fastening.In actual use, when screw and the assembling of vehicle body sheet metal counterbore, due to friction, wearing and tearing can be caused to vehicle body sheet metal, thus affect outward appearance and the quality of vehicle body sheet metal; In addition, if it is plastic to adopt traditional screw to carry out, between plastic shell and screw, easily there is space, plastic shell can not be fitted completely with screw, affect plastic effect and protection effect.
Summary of the invention
In order to overcome above-mentioned existing problem, the utility model provides and a kind ofly can not cause wearing and tearing, plastic respond well, plastic screw that protection effect is good to vehicle body sheet metal.
The utility model solves the technological scheme that its technical problem adopts: a kind of plastic screw, the screw afterbody comprise screw head, being connected with screw head, screw head is provided with spherical crown in the side away from screw afterbody, spherical crown is provided with and screws groove, the sidewall of screw afterbody is provided with screw thread, described screw head is connected with spherical crown and joint is provided with a circle projection, and the surface of the surface of the surface of screw head, spherical crown, projection is equipped with plastic shell, plastic shell and projection interfix, and plastic shell and screw head, spherical crown, protruding integral molded plastic are shaping.
The diameter of described spherical crown is greater than the diameter of screw head.
The diameter of described projection is similar to the diameter of spherical crown.
The described groove that screws is straight groove, cross recess or hexagonal flower shape groove.
The screw thread that the sidewall of described screw afterbody is arranged is Full Thread FT.
The screw thread that the sidewall of described screw afterbody is arranged is partial thread.
Described projection sectional shape be square, circular, trapezoidal or triangle.
The material of described plastic shell is nylon material.
Described screw head, screw afterbody, spherical crown are connected for integral type with protruding.
The beneficial effects of the utility model are, the utility model is provided with plastic shell outside screw head, spherical crown, during assembling, plastic shell can prevent screw from directly contacting with vehicle body sheet metal, well can protect the external protection of vehicle body sheet metal, avoid screw to the wearing and tearing of vehicle body sheet metal, screw is also played to the effect of protection and sealing simultaneously; The connection of screw head and spherical crown goes out to be provided with projection, the diameter of spherical crown is greater than the diameter of screw head, and time shaping during injection moulding, projection section can hold more plastics, avoid countersunk head outer rim plastic uneven even cannot be plastic phenomenon, improve plastic efficiency and yield rate; Plastic shell adopts nylon material, and shaping with screw head, spherical crown, protruding integral molded plastic, plastic enclosure can form the groove suitable with boss when molding and forming, avoids between plastic shell and countersunk head and occurs space, improve plastic tautness.
