Summary of the invention
The purpose of this utility model is to provide a kind of acerous screws in four directions, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of acerous screw in four directions, including screw terminal
And screw rod, the screw terminal include square block, arc-shaped corner, cavity and notch, the four corners at the top of the square block are all solid
Surely there is arc-shaped corner, cavity is provided at the top of the square block, and the top of cavity inside is provided with notch, the screw terminal
The middle position of bottom is fixed with screw rod, and threading, the bottom setting of the screw rod are provided on the outside of the screw rod
It is fluted.
Preferably, the screw rod be in cylindrical structure, threading structure in a ring, and the outer radius of threading from upper and
Under be gradually reduced.
Preferably, the notch is in " ten " font structure.
Preferably, the hemispherical structure of the groove, and the bottom of groove and the bottom of screw rod are located at same horizontal line.
Preferably, the screw terminal and screw rod are all iron and steel material quality, and the surface of screw terminal and screw rod is all provided with
Zinc coating.
Compared with prior art, the utility model has the beneficial effects that the utility model is four directions by setting screw terminal
Shape facilitates screw binder in bookbinding to put forth effort to block screw terminal, brings convenience to staff, and be at the top of screw terminal
Four directions will not damage product without angular because of corner angle, and the groove of screw rod bottom can have the mounting hole of protrusion mutual with centre
Cooperation, make the screw and mounting hole without silk joint close in conjunction with, fastening effect is preferable, and not injured labour product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of internal structure of the utility model；
Fig. 3 is the structural schematic diagram of the utility model screw terminal.
In figure: 1, screw terminal；101, square block；102, arc-shaped corner；103, cavity；104, notch；2, screw rod；3, it rubs with the hands
Tooth；4, groove.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, a kind of embodiment provided by the utility model: a kind of acerous screw in four directions, including 1 He of screw terminal
Screw rod 2, screw terminal 1 include square block 101, arc-shaped corner 102, cavity 103 and notch 104, the quadrangle at 101 top of square block
Place is all fixed with arc-shaped corner 102, and the top of square block 101 is provided with cavity 103, and the top inside cavity 103 is provided with
Notch 104, the middle position of 1 bottom of screw terminal are fixed with screw rod 2, and the outside of screw rod 2 is provided with threading 3, screw rod 2
Bottom setting fluted 4, screw terminal 1 and screw rod 2 are all iron and steel material quality, and screw terminal 1 and the surface of screw rod 2 are all arranged
There is zinc coating, iron and steel material quality makes the screw comparatively robust, and zinc coat has good rust-proof effect, and relatively beautiful.
In the present embodiment: square block 101 so as to the screw bookbinding make to facilitate binder put forth effort to block screw terminal 1 into
Luggage is ordered, and arc-shaped corner 102 protects product, and the corner angle of square block 101 is avoided to damage product, will not be because
Corner angle sharply scratch operator, easy to use, offer convenience to operator.
Attached drawing 1 and Fig. 2 are please referred to, screw rod 2 is in cylindrical structure, the structure, and the outer radius of threading 3 in a ring of threading 3
It is gradually reduced from top to bottom.
In the present invention, by the way that screw rod 2 is screwed in the mounting hole to match, so that the screw consolidates product
It is fixed, and the bookbinding of the screw is convenient in the variation of 3 radius of threading, brings convenience to the operation of staff.
Attached drawing 2 and Fig. 3 are please referred to, notch 104 is in " ten " font structure；The hemispherical structure of groove 4, and the bottom of groove 4
Portion and the bottom of screw rod 2 are located at same horizontal line.
