Abstract
A one-time screw-striking screw comprises a body, a tightening screw and a drill head, where the body has a hollow interior and can be provided to thread with the tightening screw; the head of the tightening screw is screw provided with the drill head, and the rear is provided to be driven by the tool, and the middle section is equipped with an external screw tooth which is occluded with the head of the body; the exterior of the body is provided with a screw thread portion and a deformation portion; and the peripheral surface inside the head of the body is equipped with a occluding portion which can keep the occluding relationship with the external screw tooth of the tightening screw when the hole enlarges under the situation of humidity, or a blocking portion which can prevent the body from loosing is arranged between the enlarged blocking edge of the body and the corresponding face of the tightening screw.
Description
Technical field
The utility model relates to a kind of screw of once attacking nail, described screw of once attacking nail is widely used in gypsum board, sheet metal, plank, plastic board, wall etc., mainly relates to plastic body and can keep with the occluding relation of packing screw when the wet environment UR and prevent that body from attacking the technique improvement that pine moves back in the nail process.
Background technique
The screw of once attacking nail of conventional known, please consult Fig. 1: it is known perspective exploded view of once attacking the screw of nail.Described known screw of once attacking nail mainly is made up of body 10, packing screw 20, drill bit 30, wherein:
Yet there are following two problem and defectives that wait to overcome solution in above-mentioned known screw of once attacking nail at least when practical application:
One, because body 10 is made by plastics (nylon) material, be subjected to the influence of environmental air humidity easily, cause the internal diameter of body 10 heads, meeting reaming when there was dampness in the air, meeting shrinkage cavity when air drying, as shown in Figure 2, under the reaming situation, packing screw 20 can't with body 10 interlocks, and then rotate so can't drive body 10, cause the situation that retracts ahead of time; Under the shrinkage cavity situation, packing screw 20 retracts the locking strength of the strength of body 10 variant parts 13 greater than body 10 screw sections 12, causes the situation of external screw thread 21 idle running of body 10.
Two, as Fig. 3, Fig. 4 and shown in Figure 5, the known screw of nail of once attacking is when locking object 2, because packing screw 20 can't produce barrier effect to body 10, so the screw section 12 of body 10 can withdraw by synchronous pine when variant part 13 beginning torsional deformations, just can't closely lock knot and fix object 2 at all.
