Abstract
The invention discloses self-locking screw, including the shank of screw being connected and head of screw, the cylindrical of shank of screw arranges external screw thread, it is characterized in that: the root that shank of screw is connected with head of screw arranges cannelure, it is filled with by plastic material in cannelure, plastic material after filling forms cylinder cylindrical, and the outer diameter of a circle of cylinder is equal to the major diameter of thread of shank of screw, and the surface perimeter of cylinder cylindrical lays some axial gap grooves；The bottom end face that head of screw connects with cannelure is provided with abnormity counterbore, and plastic material is filled into abnormity counterbore and is filled up.The present invention has self-locking function, effectively prevents connection from loosening, simple in construction simultaneously.
Description
Technical field
The present invention relates to a kind of fastener products, be specifically related to a kind of self-locking screw.
Background technology
At present, the nut product of band self-locking function can be found everywhere, but the screw product of band self-locking function but can not
See, so, when only workpiece being tightened fixing with screw, it is difficult to accomplish effectively to prevent from coupling to loosen, and to accomplish having
The connection that prevents of effect loosens, it is necessary to using some ancillary methods, structure is complicated.
Summary of the invention
The problem existed in view of currently known technology, the technical problem to be solved in the present invention is to be to provide one to have certainly
Locking function, effectively prevents from coupling loosening, the self-locking screw of simple in construction simultaneously.
The present invention implements by the following technical programs:
Self-locking screw, including the shank of screw being connected and head of screw, the cylindrical of shank of screw arranges external screw thread, it is characterised in that: spiral shell
The root that nail rod is connected with head of screw arranges cannelure, is filled with by plastic material, the plastic material after filling in cannelure
Forming cylinder cylindrical, the outer diameter of a circle of cylinder is equal to the major diameter of thread of shank of screw, and the surface perimeter of cylinder cylindrical lays some axles
To gap slot.
The bottom end face that head of screw connects with cannelure is provided with abnormity counterbore, and plastic material is filled into abnormity counterbore and incites somebody to action
It fills up.
Use after technique scheme, when the shank of screw of screw is screwed into the screwed hole of workpiece and during near position, screw pole-footing
Plastic material in portion's cannelure can enter workpiece screwed hole the crimp by workpiece screwed hole, the plastics of crimp
Material not only enters axial gap groove and can fill up whole screwed hole gap, and then makes to be formed between plastic material and screwed hole
Seal vacuum state, produce powerful anti-loosening locking power between plastic material and screwed hole, therefore can effectively prevent screw-driving
After connection loosen, screw has self-locking function, simultaneously simple in construction.
Accompanying drawing explanation
The present invention has a drawings described below:
Fig. 1 is the structural representation of the present invention,
Fig. 2 is the A-A view of Fig. 1.
Detailed description of the invention
Describe relevant details and the operation principle of the specific embodiment of the invention below in conjunction with the accompanying drawings in detail:
As it can be seen, the self-locking screw of the present invention, including the shank of screw 2 being connected and head of screw 1, the cylindrical of shank of screw 2 is arranged
External screw thread, the root that shank of screw 2 is connected with head of screw 1 arranges cannelure 4, is filled with by plastic material 3, fills out in cannelure 4
Plastic material 3 after filling forms cylinder cylindrical, and the outer diameter of a circle of the cylinder of plastic material 3, equal to the major diameter of thread of shank of screw 2, is moulded
The surface perimeter of the cylinder cylindrical of material material 3 lays axial gap groove 6 at six；The bottom end face that head of screw 1 connects with cannelure 4
Being provided with hexagon counterbore 5, plastic material 3 is filled into hexagon counterbore 5 and is filled up.
Claims (2)
