Abstract
The invention relates to a self-tapping antiskid screw which comprises a screw rod. The inside of the screw rod is hollow, screw teeth are bestrewed on the outside of the screw rod along the length direction of the screw rod, a cross groove is formed in one end of the screw rod, the other end of the screw rod is flat or conical, and screw pitches of the screw teeth are not equal. The self-tapping antiskid screw is mounted on the rubber or wood materials, rubber or wood products can be effectively fixed, fixed components cannot be stripped by the aid of the screw teeth with unequal pitches, and the self-tapping antiskid screw is simple and practical.
Description
Technical field
The present invention relates to a kind of screw, particularly a kind ofly can shoot rubber or the anti-skidding again self tapping Antiskid screw of wood materials.
Background technique
At present, conventional Antiskid screw, has plenty of and increases bath mat in the nut bottom of screw, some use expansion sleeves, these screws fixedly play good anti-skidding effect to steel part, but for wooden or quality of rubber materials, these screws can not play anti-skidding fixing effect.We have developed and a kind ofly can shoot rubber or the anti-skidding again self tapping Antiskid screw of wood materials for this reason.
Summary of the invention
The present invention seeks to provide a kind of can shoot rubber or the anti-skidding self tapping Antiskid screw of wood materials to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: a kind of self tapping Antiskid screw, comprise screw rod, the inner hollow of described screw rod, it is characterized in that: the outside of described screw rod is covered with thread along spiro rod length direction, one end of described screw rod is with cross recess, and the other end of described screw rod is flush end or cone end; The pitch of described thread is unequal.
Preferably, the hollow structure of described inside screw is cylindrical.
Preferably, the pitch of described thread diminishes gradually from cross recess end.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Self tapping Antiskid screw of the present invention is arranged on rubber or wood materials, can be fixed rubber or wood-based product well; The thread of Unequal distance makes the parts fixed slide tooth, simple and practical.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the sectional view of self tapping Antiskid screw of the present invention;
Accompanying drawing 2 is the plan view of self tapping Antiskid screw of the present invention;
Wherein: 1, screw rod; 2, cross recess; 3, thread.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is the sectional view of self tapping Antiskid screw of the present invention, comprise screw rod 1, the inner hollow of described screw rod 1, the outside of described screw rod 1 is covered with thread 3 along screw rod 1 length direction, one end of described screw rod 1 is with cross recess 2, and the other end of described screw rod 1 is flush end or cone end.
In the present embodiment, as shown in accompanying drawing 1, Fig. 2, described thread 3 is Unequal distance thread; The pitch of described thread 3 reduces gradually from cross recess 2 end, when using flat head or crosshead instrument to apply external force to cross recess 2, Unequal distance thread 3 incites somebody to action more and more drive fit with rubber material or wooden material, when cross recess 2 end is concordant with outside material, coupling mechanism force is now maximum value, this makes the more firm of the Contact of product or parts, can not slide tooth.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
Claims (3)
1. a self tapping Antiskid screw, comprises screw rod, and the inner hollow of described screw rod, is characterized in that: the outside of described screw rod is covered with thread along spiro rod length direction, and one end of described screw rod is with cross recess, and the other end of described screw rod is flush end or cone end; The pitch of described thread is unequal.
2. self tapping Antiskid screw according to claim 1, is characterized in that: the hollow structure of described inside screw is cylindrical.
3. self tapping Antiskid screw according to claim 1 and 2, is characterized in that: the pitch of described thread diminishes gradually from cross recess end.
