Screw structure

This creation system relates to a screw structure, especially one that can improve the cutting and chip removing ability of the screw, and can reduce the torque when the screw is screwed, thereby achieving the effect of saving labor and time saving, and further preventing cracking of the wood. The lack of production, the screw structure that can improve the quality of the construction of the screw.

According to the wood screw, it is mainly used for the connection of wooden workpieces. The wood screw has the function of tapping the hole directly in the wood material, so that the wooden workpiece can be quickly locked.

As shown in FIG. 1, the screw 1 includes a screw head 11 and a rod body 12 extending downward from the screw head 11. The outer circumference of the rod body 12 is provided with a spirally wound screw 13 and an end below the rod body 12. The tip end portion 14 is provided for the cutting wood and the chip removing effect of the lifting screw 1. The rib rib 15 is protruded between the threaded body 13 and the thread 13 by the rod body 12, and the rib 15 is raised by the rib 15 The cutting and chip removal effect of the screw 1.

The above-mentioned conventional screw 1 can certainly improve the effect of the screw 1 screwing into the drilling operation; however, how to design a screw 1 structure to ensure that the screw 1 does not crack during the drilling screwing operation; And it can reduce the screwing torque and smoother discharge of wood chips, which has become a major issue for the screw manufacturers.

The main purpose of this creation is to effectively solve the problem of the screw which is easy to cause the wooden workpiece to be cracked due to excessive pressure, which will damage the structural strength of the wooden workpiece and the lack of the screwing effect of the nail.

The technical means for achieving the above object is: a screw structure, a rod body extending downward from the screw head, the outer peripheral edge of the rod body is provided with a threaded thread, and the lower end of the rod body is provided with a pointed tail portion. The thread is not extended to the tip end portion, and the pointed tail portion is convexly provided with at least one rib, and the end surface of the rib is formed into a wavy tooth shape.

The effect of the above-mentioned technical means is that the end surface of the rib is formed into a wavy tooth shape by the at least one rib protruding from the pointed end of the screw, thereby improving the cutting of the screw and The chip removal ability can reduce the torque when the screw is screwed in, which can save the labor and save time, and use this special end face design to cut, chip, destroy and so on the wood fiber, and prevent the wood from cracking. The lack of production can improve the quality of the construction of the screw.

Another effect that can be achieved by the above technical means is that the ribs are further formed by point-like ribs arranged in a point-like stud, the points of the ribs being arc-shaped or It is tapered, and the special end face design can cut, chip, and damage the wood fiber; thereby improving the cutting and chip removing ability of the screw, and reducing the torque when the screw is screwed, thereby achieving The construction saves labor and saves time, and further prevents the occurrence of cracks in the wood, which can improve the quality of the construction of the screw.
