Description
[technical field]
The present invention relates to the technical fields of the technical field of screw, especially self-tapping screw.
[background technique]
Self-tapping screw is used for nonmetallic or softer metal, does not have to bottoming hole and tapping；Self-tapping screw is tip, in this way
Ability " self tapping "；Normal screws are all tack, and thickness is consistent, and self-tapping screw is to say: the hole of brill is the hole without tapping,
Screw and general difference, head are sharp, and tooth is somewhat like with chipless screw tap, can not have to the direct precession of tapping away from bigger
It goes, usually using this method, it, by the screw thread of its own, can will be consolidated on the material being consolidated for metal and plastic cement
Body " attack-bore, squeeze, pressing " goes out corresponding screw thread, is allowed to mutually be fitted close, and existing self-tapping screw anti-loosening property is generally poor, holds
It easily loosens, screw head is shorter, it has not been convenient to hang thing in screw head, and spanner bayonet is mostly cross, be easily damaged during turning.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of self-tapping screw is proposed, can have relatively strong locking
Effect, screw head is longer, and thing can be hung above, and spanner bayonet is hardly damaged.
To achieve the above object, the invention proposes a kind of self-tapping screw, including screw rod, screw head, rib, link block, institutes
The screw surface coiling stated is equipped with screw thread, and the screw thread protrudes setting, and the screw rod lower end is equipped with screw rod tip, described
Screw rod upper end is equipped with rib, and the rib upper end is equipped with link block, and the link block upper end is equipped with screw head, the screw head
Top surface is equipped with spanner bayonet.
Preferably, the screw head lower end is equipped with the conical surface, described lesser one end of conical surface diameter is set towards link block
It sets.
Preferably, the center of circle of the screw rod, screw head, rib, link block is on the same axis.
Preferably, the rib lower end is equipped with non-slip texture towards one end of screw rod.
Preferably, the spanner bayonet is "-" type spanner bayonet.
Preferably, the screw rod, screw head, rib, link block surface are equipped with plating antirust coat.
Preferably, the screw rod, screw head, rib, link block are an integral molding structure.
Preferably, the cross section of the screw rod, screw head, rib, link block is circle.
Preferably, the diameter of the rib is greater than the diameter of screw rod, screw head and link block.
Beneficial effects of the present invention: the present invention is arranged by setting rib by protruding screw head, when screw tightening,
Screw head can be used as hook, by setting "-" type for the spanner bayonet in screw head, spanner bayonet be effectively prevent to twist
It is damaged during dynamic, by the way that anti-skid bulge is arranged in rib lower end, reinforces the frictional force between screw and component, prevent from loosening.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of self-tapping screw structure schematic diagram of the present invention.
In figure: 1- screw rod, 2- screw head, 3- rib, 4- link block, 11- screw thread, 12- screw rod tip, 21- spanner bayonet,
The 22- conical surface, 31- non-slip texture.
[specific embodiment]
Refering to fig. 1, a kind of self-tapping screw of the present invention, including screw rod 1, screw head 2, rib 3, link block 4, the screw rod 1
Surface coil is equipped with screw thread 11, and the screw thread 11 protrudes setting, and 1 lower end of screw rod is equipped with screw rod tip 12, described
1 upper end of screw rod is equipped with rib 3, and 3 upper end of rib is equipped with link block 4, and 4 upper end of link block is equipped with screw head 2, described
2 top surface of screw head be equipped with spanner bayonet 21,2 lower end of screw head be equipped with the conical surface 22,22 diameter of the conical surface lesser one
End towards link block 4 be arranged, the screw rod 1, screw head 2, rib 3, link block 4 the center of circle on the same axis, the gear
3 lower end of side is equipped with non-slip texture 31 towards one end of screw rod 1, and the spanner bayonet 21 is "-" type spanner bayonet, described
Screw rod 1, screw head 2, rib 3,4 surface of link block are equipped with plating antirust coat, the screw rod 1, screw head 2, rib 3, link block 4
Be an integral molding structure, the screw rod 1, screw head 2, rib 3, link block 4 cross section be circle, the rib 3
Diameter is greater than the diameter of screw rod 1, screw head 2 and link block 4.
The course of work of the present invention:
A kind of self-tapping screw of the present invention is directed at required fixed position during the work time, by the screw rod tip 12 of screw rod 1,
Straight screwdriver is blocked into spanner bayonet 21, spanner is turned by screwdriver, passes through the cooperation of screw rod tip 12 and screw thread 11
Fixed position needed for screw rod 1 is screwed into, the effect when being screwed to certain depth due to rib 3 limits screw rod 1, and rib 3
The non-slip texture 31 of lower end can reinforce frictional force, prevent from loosening.
Above-described embodiment is the description of the invention, is not limitation of the invention, after any pair of simple transformation of the present invention
Scheme all belong to the scope of protection of the present invention.
