Abstract
The utility model relates to a screw. A first section thread adjacent to a screw head and a second section thread adjacent to a screw tail are respectively arranged on a rod body of the screw, wherein the included angle between an upper screw thread surface and a lower screw thread surface of a screw thread of the second section thread is more than 90 degrees, and the screw thread of the second section thread can extend to the screw tail. By adopting the design of the screw thread of the second section thread of the screw, when the screw is used for the combination for a gypsum plate and a thin iron plate, and the screw is rammed into the gypsum plate (or other materials) through an air gun, the other end of the gypsum plate (or other materials) is not blown open due to the impact force, therefore, an excessively large clearance between the gypsum plate and the thin iron plate is not caused to affect the binding force.
Description
Technical field
The utility model relates to a kind of combining and the combination screw of other unlike material object of gypsum board and sheet iron that can be used for.
Background technique
The general employed screw of known fixed object, and with different technological thought many different creation designs are arranged according to different demand effects, but its creation request is consolidated effect nothing more than penetration rate, chip removal speed and final spiral shell.And reaching aforementioned purpose for asking, the design of screw has single hop screw thread, two sections screw threads, and the variation of identical thread helical pitch angle or different thread helical pitch angles.
Yet, the thread design of screw also must be considered the material characteristic of bond, as: will screw when being applied to combining of similar gypsum board and sheet iron, when screw is squeezed into gypsum board (or other material) with air gun, the other end of gypsum board (or other material) can cause because of the impulse force relation and burst shape, and then causes producing excessive gap between gypsum board and the iron plate and influence combination force.
The model utility content
Main purpose of the present utility model is to provide a kind of combining and the combination of other unlike material object and can not cause the screw that bursts in conjunction with object of gypsum board and sheet iron that can be used for.
For reaching above-mentioned purpose, have first section screw thread of close screw terminal and second section screw thread of close screw tail on its screw rod body of screw of the present utility model, and wherein the last thread face of the thread of second section screw thread is spent greater than 90 with the angle of following thread face, and the thread of this second section screw thread is extended to the screw tail.
Thread design by second section screw thread of the utility model screw, must be when this case screw applies to combining of similar gypsum board and sheet iron, when screw being squeezed into gypsum board (or other material) with air gun, the other end of gypsum board (or other material) can not cause because impulse force closes and burst shape, therefore can not cause producing excessive gap between gypsum board and the iron plate and influences combination force.

Embodiment
See also shown in Figure 1ly, the utility model screw can be used for the combination of combining of gypsum board and sheet iron and other unlike material object.Having two sections screw threads on the screw rod body, be respectively first section screw thread 2 and second section screw thread 3, is two threads 21 and 22 at the first section screw thread 2 near screw terminal 1, and second section screw thread 3 of close screw tail 10 also is two threads 31,32.
As shown in Figure 2, the last thread face 311,321 of the thread 31,32 of this second section screw thread 3 and the included angle A of following thread face 312,322 are greater than 90 degree, and the thread of this second section screw thread 3 is extended to screw tail 10.
Certainly, in enforcement of the present utility model, first section screw thread 2 of screw also can be designed to single thread 21, second section screw thread 3 also can be designed to single thread 31, and the thread of this second section screw thread 3 is extended to screw tail 10, make the integral body of this case model utility use on the category and can reach widely: two threads 31 of second section screw thread 3 of single thread 21 collocation of first section screw thread 2,32, or single thread 31 of second section screw thread 3 of single thread 21 collocation of first section screw thread 2, or two threads 21 of first section screw thread 2, single thread 31 of second section screw thread 3 of 22 collocation, or two threads 21 of first section screw thread 2, two threads 31 of second section screw thread 3 of 22 collocation, 32.But mainly focusing on wherein: no matter the thread of second section screw thread 3 is that single thread still is two threads, the last thread face 311 of its thread 31 is spent greater than 90 with the included angle A of following thread face 312, the last thread face 321 of thread 32 is spent greater than 90 with the included angle A of following thread face 322, and the thread of this second section screw thread 3 is extended to screw tail 10.
When screw of the present utility model is applied to combining of similar gypsum board and sheet iron, with air gun screw is squeezed into gypsum board, the gypsum board the other end can not cause because impulse force relation and burst shape, therefore can not cause producing excessive gap between gypsum board and the iron plate and influences combination force.Though illustrating of the utility model utilization object is to be the narration of gypsum board and sheet iron with the bond, therefore do not limit to utilization of the present utility model in conjunction with object or material.
Claims (3)
1. screw, have first section screw thread of close screw terminal and second section screw thread of close screw tail on its screw rod body, it is characterized in that: the last thread face of the thread of described second section screw thread is spent greater than 90 with the angle of following thread face system, and the thread of described second section screw thread can be extended to the screw tail.
2. screw as claimed in claim 1 is characterized in that: described second section screw thread is single thread.
3. screw as claimed in claim 1 is characterized in that: described second section screw thread is two threads.
