Abstract
A kind of screw, including screw head (1) and screw rod (2), it is characterized in that the shape of screw head (1) is made of two or more sagittal curvature section (11) head and the tail connections, the sagittal curvature section (11) forms recess (12) in junction, and the sagittal curvature section (11) is distributed around screw central axis.The screw of such shape is able to solve the slip phenomenon of screw head of screw in spinning in and out.
Description
Technical field
The present invention relates to a kind of screws.
Background technique
Screw is one of most common fastener, but in use, screw often will appear spiral shell in spinning in and out
Ailhead slip phenomenon；Such as in screw corrosion, it is desirable to screw be unloaded down, whether cross recess, outer-hexagonal or interior
Slip phenomenon can all occur in the screw of hexagonal, and sometimes even original screw head shape is all by destroying and cannot remove
Come.These failure phenomenons of screw in use propose requirements at the higher level to the shape of screw head: how to pass through head of screw
Shape driving screw rotation, make the impetus of spanner stronger reliable, while screw disassembling is more convenient.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of preferred embodiment for existing background technique.
The technical scheme of the invention to solve the technical problem is: a kind of screw, including screw head (1) and spiral shell
Bar (2), it is characterised in that the shape of screw head (1) is by two or more sagittal curvature section (11) head and the tail connection groups
At, the sagittal curvature section (11) forms recess (12) in junction, and the sagittal curvature section (11) is in screw
Mandrel distribution.
The shape of above-mentioned screw head (1) increases the scale of depressed section and opposed lugs point；It is cooperating therewith
Sleeve when installing or removing screw, be just not easy to slip, especially can only use the quality softer metal such as copper in screw
In the case of, its more aobvious superior performance.
The shape of above-mentioned screw head (1) is connected by several sagittal curvatures (11) head and the tail, and shape is just than milder beauty
It sees, and outer-hexagonal bolts head just seems stiff.
Above-mentioned screw head (1), end face, in order to keep screw head more attractive, can press while head forms
Print some decorative patterns (13).
Compared to the prior art the present invention has the advantages that the shape of screw head designed by the present invention, increases recessed
The scale of concave portion point and opposed lugs point, is not easy to slip；Keep the shape of ailhead more attractive simultaneously, there is decorative performance.
Detailed description of the invention
By following attached drawing, this patent content is described in detail:
Fig. 1 is the head shape schematic diagram of the embodiment of the present invention；
Fig. 2 is the stereoscopic schematic diagram of the embodiment of the present invention；
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
It as shown in Figure 1 and Figure 2, is the embodiment of the present invention structural schematic diagram.Screw head is at column, the inside shape of sleeve
Shape and screw head shape cooperate, and rotational sleeve can drive screw spinning in and out, realize the disassembly and assembly of screw.
Screw can be using the forming such as cold pier, casting.
Claims (3)
1. a kind of screw, including screw head (1) and screw rod (2), it is characterised in that the shape of screw head (1) be by two or
More than two sagittal curvature section (11) head and the tail connection compositions, the sagittal curvature section (11) is formed in junction to be recessed
(12), the sagittal curvature section (11) is distributed around screw central axis.
2. screw according to claim 1, it is characterised in that the end face of the screw head (1) imprints some decoration figures
Case (13).
3. screw according to claim 1, it is characterised in that the screw head (1) is in a thickness direction at column.
