Description
Technical Field
The utility model belongs to the technical field of the hardware, especially, relate to a novel screw subassembly.
Background
The screw is a tool for fastening the parts of the object step by utilizing the physics and mathematical principles of the inclined circular rotation and friction of the object.
When the existing screw is screwed into wood, holes need to be punched in advance before screwing, and if the existing screw is directly screwed in without punching, the joint of the wood and the screw is easy to crack, so that the product is damaged. Meanwhile, when the screw is used, the phenomenon of screw sliding caused by abrasion of a screw hole is often encountered, so that the screw is difficult to screw or remove, and a fixed object is damaged to a certain extent.
Disclosure of Invention
The to-be-solved problem of the utility model is to provide a simple structure, the difficult smooth silk, the novel screw assembly that need not punch in advance.
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a novel screw assembly, includes the head and the body of rod that links to each other with the head, the head is provided with the screw hole, be provided with in the screw hole and enclose with the supporting detachable rubber of screw hole shape, body of rod periphery is provided with the screw thread, the screw thread includes screw thread and lower screw thread, it is slick and sly to go up the screw thread edge, the lower screw thread edge is the wave, and the crest position at wave edge makes progress slick and sly arch, the border position of going up screw thread and lower screw thread is thin in its root position, body of rod bottom is provided with the tail point.
The head and the rod body are of an integrally formed structure.
The upper thread and the lower thread are of an integrally formed structure.
Since the technical scheme is used, the utility model has the advantages of simple overall structure, the lower thread edge that the body of rod leaned on lower position is the wave, the decurrent rounding off of crest position at wave edge, when this design made the screw in downwards, the crest at wave edge earlier with the timber contact, make its screw in ligneous resistance reduce, in the time of the screw in, because lower thread edge is the wave, the crest position at wave edge rounding off upwards, the area with timber contact cutting has been increased in other words, the chip removal space has still been increased, and simultaneously, it is slick and sly to go up the thread edge, after the lower thread screw in, the cavity that the wave line was left makes the light screw in of upper thread, finally make this screw also can smooth screw in timber without punching in advance, can not make timber and screw junction appear the condition of fracture because of improper or the screw in by force simultaneously. In addition, be provided with in the screw hole and enclose with the supporting removable rubber of screw hole shape, during screw in and the screw of unscrewing, can put into the screw hole with dismantling the rubber circle, the screwdriver inserts rotatory screw in the rubber circle, has increased the parcel nature and the frictional force of screwdriver, and the difficult smooth silk of screw, when facilitating work, protection screwdrivers blade and screw hole are not worn and torn.
The utility model has the advantages that: has the advantages of simple structure, difficult thread slipping, no need of pre-punching and cracking prevention.

Detailed Description
As shown in fig. 1, the utility model relates to a novel screw assembly, including head 1 and the body of rod 2 that links to each other with head 1, head 1 is provided with a line screw hole 3, is provided with in the screw hole 3 and encloses 4 with the supporting detachable rubber of 3 shapes of screw hole, and body of rod 2 periphery is provided with the screw thread, the screw thread includes screw thread 5 and lower screw thread 6, and 5 marginal slick and sly of going up the screw thread, 6 edges of lower screw thread are the wave, and the crest position at wave edge makes progress slick and sly arch 7, and the border position of going up screw thread 5 and lower screw thread 6 is thinner than its root position, and body of rod 2 bottom is provided with tail point 8, and head 1 and the body of rod 2 are the integrated into one piece structure, and.
The utility model has the advantages of simple overall structure, the body of rod 2 is by 6 edges of lower screw thread of position down for the wave, the decurrent rounding off 7 of crest position at wave edge makes progress, when this design makes the screw in downwards, the crest at wave edge earlier with the timber contact, make its ligneous resistance of screw in reduce, in the time of the screw in, because lower thread edge is the wave, the crest position at wave edge makes progress rounding off 7, the area with timber contact cutting has been increased in other words, the chip removal space has still been increased, and simultaneously, it is slick and sly to go up the thread edge, behind the lower thread screw in, the cavity that the wave line was left makes the light screw in of screw thread, finally make this screw also can smooth screw in timber without punching in advance, simultaneously can not make timber and screw department of meeting appear the condition of fracture because of improper or the screw in force. In addition, be provided with in the screw hole 3 and enclose 4 with the supporting removable rubber of 3 shapes in screw hole, during screw in and the screw of unscrewing, can be with can dismantling in the rubber encloses 4 puts into screw hole 3, the screwdriver inserts rotatory screw in the rubber circle, has increased the parcel nature and the frictional force of screwdriver, and the difficult smooth silk that slides when facilitating work, protection screwdrivers blade and screw hole are not worn and torn.
The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
