Abstract
The utility model relates to a self-tapping screw, in particular to a self-tapping screw with a guiding portion. The self-tapping screw with the guiding portion is characterized in that the cylindrical guiding portion is arranged at the head of a thread of the self-tapping screw, and an end of the cylindrical guiding portion is conical. The cylindrical guiding portion which is additionally arranged at the head of the thread of an existing self-tapping screw is vertically nailed in by a hammer according to needs when in use of the self-tapping screw, then the self-tapping screw is screwed in by a screwdriver, and accordingly the problem of deviation of an axis when the existing self-tapping screw is screwed into a wooden member is solved well. Meanwhile, wooden materials are extruded and strengthened, and connection strength is guaranteed. In addition, the self-tapping screw with the guiding portion has the advantages of simple structure, convenience in mounting and dismounting, firmness in connection and the like.
Description
Technical field
The utility model relates to the tapping screw of a kind of tapping screw, particularly tape guide.
Background technique
It is very extensive that the connection of tapping screw between metalwork used.According to the difference of use occasion, its head often adopts cross or straight groove coiled hair, cross or shapes such as straight groove countersunk head, hexagon socket head.Packaging box often adopts nail to connect, but because intensity that nail connects and detachable performance are poor, are attacked screw gradually and substitute in the packing of some high end equipments.As being connected and fixed of the packed and transported case of the packing of numerical control machine tool, particularly high-grade high-speed machine tool, reliability height, quick-detachable tapping screw have just been adopted.But existing tapping screw in use, the axis and the problems such as junction plane out of plumb that are connected member of tapping screw often occur, and not only influence connects effect, and influences the attractive in appearance of whole packaging box.For addressing the above problem, be preboring bottom outlet on wood materials at present, utilize tapping screw to fix then.Though but the method solves the axis deviation problem of tapping screw and since preboring bottom outlet, the material of Wood member is removed, and causes tapping screw that the extruding of the screw-in hole material around of Wood member is weakened, thereby makes the join strength reduction of hophornbeam member.
Summary of the invention
The purpose of this utility model is to address the deficiencies of the prior art, and provides a kind of and both can guarantee effectively that the axis of tapping screw is vertical with the junction plane that is connected member, can guarantee the tapping screw of the tape guide that is connected firmly again.
The utility model is realized by following skill scheme: a kind of tapping screw of tape guide, it is characterized in that having the column guide portion at the head of tapping screw screw thread, and the end of column guide portion is a taper.
The cross section of above-mentioned column guide portion can be circle and polygonal.
The transition position of above-mentioned column guide portion and screw thread is a conical surface, is distributed with conical surface screw thread on the conical surface.
Because the utility model has increased the column guide portion at the screw head of existing tapping screw, so in use with hammer the cylindric guide portion of tapping screw is vertically hammered on request earlier, just tapping screw can screwed in screw-driver then, axis deviation problem when well having solved common tapping screw and screwing in Wood member, simultaneously wood materials is carried out extruding and strengthened, guaranteed the intensity that connects.
The utlity model has rational in infrastructurely, install, convenient disassembly, characteristics such as be connected firmly.
Description of drawings
Accompanying drawing 1 tapping screw structural representation.
Embodiment
Shown in accompanying drawing 1, increased column guide portion 1 at screw thread 2 heads of common tapping screw, and the end of column guide portion is taper 6, be conical surface 4 at the transition position of column guide portion and screw thread, be distributed with conical surface screw thread 5 on the conical surface.
During use, tapping screw is placed on the position that need hammer into, and the axis that guarantees tapping screw is with to hammer into face vertical, with hammer guide portion is knocked in the Wood member, the column guide portion has tentatively carried out the extruding reinforcement to the wood materials around it like this, screw in the Wood member with the screw thread 2 of screw-driver with tapping screw this moment again, and the head 3 of tapping screw is overlapped with the conical surface of irony member, finishes interconnect function.Because it is the guide portion 1 of tapping screw and the transition position of screw thread 2 have conical surface 4, are distributed with conical surface screw thread 5 on the conical surface 4, and the existence of conical surface screw thread 5 is arranged just, just smooth and easy more laborsaving when tapping screw screw thread 2 screws in Wood member.
The cross section of column guide portion 1 can be circle or polygonal according to the use occasion difference.
Claims (3)
1. the tapping screw of a tape guide is characterized in that having column guide portion (1) at the head of tapping screw screw thread, and the end of column guide portion is a taper.
2. the tapping screw of tape guide as claimed in claim 1, the transition position that it is characterized in that above-mentioned column guide portion (1) and screw thread (2) is conical surface (4), is distributed with conical surface screw thread (5) on the conical surface (4).
3. the tapping screw of tape guide as claimed in claim 2, the cross section that it is characterized in that above-mentioned column guide portion (1) can be circle and polygonal.
