Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a self tapping screw with prevent excursion mechanism, including screw main part 1, screw main part 1 is including nut 101 and screw rod 102, and screw rod 102 outward appearance wall has seted up thread groove 7, screw rod 102 outward appearance wall closes soon through the screw thread to be connected with the combination cover 4 of being connected with nut 101 block, and combination cover 4 is cylindrical structure, will combine the outer surface wall of 4 bottom butt materials of cover, it makes screw rod 102 imbed in the material through thread groove 7 to rotate screw main part 1 again, realize the installation of screw main part 1, and through the design of columniform combination cover 4, make and combine 4 bottoms of cover fully and the contact of material outward appearance wall, and then guaranteed the straightness that hangs down when screw main part 1 is installed.
Specifically, as shown in fig. 1 and fig. 2, the outer wall fixed mounting of screw 102 has connecting block 3, one side elastic connection that screw 102 was kept away from to connecting block 3 has flexure strip 2, after screw main body 1 combines with the material, when screw 102 closed with the material soon through the external screw thread and is connected, the flexure strip 2 of the horizontal end elastic connection of connecting block 3 of screw 102 outer wall fixed mounting can be through the elastic potential energy joint of its self on the internal thread of material, make the material inside strengthen with screw 102 frictional force, and then avoided screw 102 to take place to become flexible, thereby improved the stability that the tapping screw used.
Specifically, as shown in fig. 1, an elastic cushion 5 is fixedly installed at the bottom of the coupling sleeve 4 to prevent the bottom of the coupling sleeve 4 from scraping paint surface of the material due to over rotation when the screw body 1 is installed.
