Abstract
The utility model discloses a bolt with a sawtooth head, comprising an end head and a bolt body. The bolt body comprises a screw-thread section provided with an encircling screw-thread, and a bolt head arranged on the end part of the screw-thread section, wherein the external surface of the bolt head is provided with encircling screw-thread-type sawteeth; the thread pitch of the sawteeth is identical with that of the screw-thread section, and the sawteeth are in smooth transition with the screw thread of the screw-thread section; and the bolt body is also provided with a chip removal channel for removing the chips. In the utility model, the bolt head is provided with the sawteeth for facilitating the entering of the bolt, so that the bolt is capable of quickly being screwed into the fiber-material product by saving labor.
Description
Technical field
The utility model relates to a kind of screw that has the zigzag fashion head.
Background technique
Connect between the structural member of lamination coating goods and often need use screw, as the connection between the wood etc.The existing tooth form that is used for the screw that connects between the lamination coating goods is generally 40 ° of tooth form angles, pitch is slightly larger than the pitch of the tapping screw of equal middle warp, but this screw that is used for connecting between the lamination coating goods is hammering into process, exist between screw thread positive and negative and the lamination coating goods area of contact big, thereby its friction torque that hammers into is big, hammers into the shortcoming of difficulty.
The model utility content
At the problem that existing situation exists, the purpose of this utility model is to provide a kind of structure the improved screw that has the zigzag fashion head.
For achieving the above object, a kind of screw that has the zigzag fashion head of the utility model, comprise termination and nail body, the nail body comprises and is provided with around the thread section of screw thread and is arranged on the ailhead of thread section end, wherein the outer surface of ailhead is provided with the sawtooth around helical, the pitch of this sawtooth is identical with the pitch of described thread section, smooth excessiveness between the screw thread of sawtooth and thread section; Described nail also is provided with the chip removal ditch that is used for chip removal on one's body.
The utility model has made things convenient for shooting of screw by sawtooth is set on ailhead, make more laborsaving when screw is shot the lamination coating goods, quicker.
Description of drawings
Accompanying drawing is the utility model structural representation.
Wherein reference character is as follows:
Termination 1, nail body 2, thread section 3, ailhead 4, chip removal ditch 21, sawtooth 41.
Embodiment
As shown in drawings, a kind of screw that has the zigzag fashion head of the utility model, comprise termination 1 and nail body 2, termination 1 is provided with fluting or cross recess, nail body 2 comprises and is provided with around the thread section 3 of screw thread and is arranged on the ailhead 4 of thread section end that wherein the outer surface of ailhead 4 is provided with the sawtooth 41 around helical.A kind of screw of zigzag fashion head that has of the utility model is by being provided with sawtooth 41 on ailhead 4, make screw when shooting, sawtooth 41 can be cut the lamination coating goods rapidly, and on cutting route, form threaded line, because the pitch of sawtooth 41 is identical with the pitch of thread section 3, smooth excessiveness between the screw thread of sawtooth 41 and thread section 3, the screw thread of thread section 3 just can be postponed this threaded line and be shot the lamination coating goods fast like this.Also be provided with the chip removal ditch 21 that is used for chip removal on the nail body 2, the detritus that sawtooth 41 machines away can be discharged by chip removal ditch 21 rapidly, thereby has further made things convenient for shooting of screw.
That a kind of screw that has the zigzag fashion head of the utility model is compared with plain screw is more laborsaving when having the link of shooting, quicker, chip removal advantage more smoothly, has made things convenient for the connection between the structure.
