Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to fig. 2, it is a schematic structural diagram of a locking hexagonal band washer self-drilling fastening screw provided by the present invention. The hexagonal band gasket drill-tail fastening screw for preventing looseness comprises a screw rod 10, a screw cap 20 arranged at one end of the screw rod 10 and an anti-skid ring 30 fixedly connected to one side of the screw cap 20. It is contemplated that the locking hex band washer drill tail fastening screw further includes functional modules, such as a wrench, a workpiece, etc., which are well known to those skilled in the art and will not be described herein.
The screw 10 comprises a screw body 11, a screw head 12 arranged at one end of the screw body 11, a thread 13 arranged on the side wall of the screw body 11, and a stop unit 14 arranged at one end of the screw body 11 close to the anti-slip ring 30.
The screw body 11 is prior art, the screw body 11 is the columniform stock, and its length can set up according to actual need.
The screw head 12 is the bit that drills the screw into the workpiece. The screw head 12 is pointed in a pointed tail shape, which makes it easier to drill the screw into a workpiece.
The thread 13 is a continuous bulge formed along a spiral line, so that friction force generated between the screw and the inner wall of the workpiece when the screw is screwed into the workpiece can be effectively reduced, and the screw can be screwed into the workpiece easily. The screw body 11, the screw head 12 and the thread 13 are all prior art and are not described herein again.
The stopper unit 14 includes a plurality of barbs 141 spaced apart from each other in the circumferential direction of the screw body 11. In a cross section perpendicular to the central axis of the screw 10, the diameter of the stopper unit 14 is equal to the diameter of the thread 13, and when the screw is screwed into the workpiece along the rotation direction of the thread 13, the stopper unit 14 is also screwed into the workpiece. The outer contour of each barb 141 is curved. The direction of rotation of the barbs 141 is the same as the direction of the helix of the thread 13 so that the barbs 141 do not interfere with the threading of the screw into the workpiece. However, when the screw is rotated in the reverse direction, the barb 141 will catch on the inner wall of the workpiece, preventing the screw from rotating.
The outer contour of the nut 20 is regular hexagon, which increases the friction between the wrench and the outer side wall of the nut 20, so that the wrench is not easy to slip in the using process, and the screw can be screwed into the workpiece more conveniently, wherein the nut 20 is a prior art and is not repeated herein.
The anti-slip ring 30 includes an anti-slip ring main body 31 abutting against one side of the nut 20 and sleeved on the screw body 11, and a plurality of anti-slip teeth 32 disposed at intervals on one side of the anti-slip ring main body 31 facing away from the nut 20. The outer diameter of the cleat body 31 is larger than the diameter of the stop unit 14 so that the stop unit 14 is screwed into the workpiece and the cleat 30 is exposed on the surface of the workpiece. The direction of inclination of each anti-slip tooth 32 is opposite to the direction of rotation of the barb 141, and when the screw is screwed into the workpiece, the anti-slip tooth 32 is also rotated into the workpiece. When the screw is unscrewed in the reverse direction, the anti-slip teeth 32 will bite the workpiece, thereby preventing the screw from loosening. The thickness of antiskid circle main part 31 is less than the height of barb 141, so that the barb protrusion in antiskid circle main part 31 one side, and then make the barb 141 all screw in after the work piece antiskid tooth 32 also follows the screw in the work piece.
The screw rod 10, the nut 20 and the anti-slip ring 30 are integrally formed, so that the whole screw is firmer and is not easy to break. In the process of screwing the screw into the workpiece, because the rotating direction of the barb 141 is the same as the spiral direction of the thread 13, and the inclined direction of the anti-slip tooth 32 is opposite to the rotating direction of the barb 141, the screwing of the screw into the workpiece is not affected. If the screw is screwed out reversely, the barb 141 and the anti-slip tooth 32 will generate a cutting action with the inside of the workpiece, so that the barb 141 and the anti-slip tooth 32 are stuck in the workpiece, and the screw is prevented from loosening and falling off.
Compared with the prior art, the utility model provides a locking hexagonal belt gasket bores tail fastening screw includes locking unit 14 to and antiskid circle 30. A barb 141 is provided on the stopper unit 14, and the rotation direction of the barb 141 is the same as the screw direction of the screw thread 13. The anti-slip ring 30 comprises an anti-slip ring body 31 and a plurality of anti-slip teeth 32 arranged on the anti-slip ring body 31 at intervals. The thickness of the anti-slip ring main body 31 is smaller than the height of the barb 141, so that the barb 141 protrudes out of one side of the anti-slip ring main body 31. Therefore, the anti-loosening barrel hexagonal belt gasket drill tail fastening screw is simple in structure, convenient to install and not easy to loosen.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
