Abstract
The invention provides a screw. The screw comprises a screw head and a screw rod, wherein the outer contour of the cross section of the screw head is a regular hexagon, and the screw rod is a full thread screw. The screw further comprises a cylindrical gasket arranged at the inner end of the screw head, the gasket and the screw head are of an integrally formed structure, and a cross-shaped groove is formed in the surface of the screw head; the body of the screw is made of 45# steel. The screw has the beneficial effects of reasonable design, simple structure, convenient use, firmness and durability, and the work efficiency is improved.
Description
Technical field
The invention belongs to fixed component field, especially relate to a kind of screw.
Background technique
Screw is a kind of fixed component widely used in metallic material, is mainly used in the industries such as building, decoration, transport.In prior art, when with fastened by screw product, usually need to overlap a cylindrical spacer in lead screw, be used for preventing the surface of fastened product not by screw terminal compressive strain.This pad is separated with screw rod, in use, first pad to be enclosed within screw rod, and then secured product, and installation efficiency is low.In addition, when screw uses dismounting, after screwing down with corresponding screw-driver, screw is not lifted down together, needs, with out hand-held, to make troubles to user.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of reasonable in design, and structure is simple, easy to use, robust screw.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of screw, comprise screw terminal and lead screw, the cross section external frame of screw terminal is regular hexagon, lead screw is full flight screw, it is characterized in that: also comprise the cylindrical body pad being arranged on screw terminal the inner, pad and screw terminal are formed in one structure, and described screw terminal surface arranges cross groove; Described screw body is made up of No. 45 steel.
The groove on described screw terminal surface is arranged to three-back-shaped.
The advantage that the present invention has and good effect are: reasonable in design, and structure is simple, easy to use, sturdy and durable, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure:
1, screw terminal; 2, lead screw; 3, pad; 4, groove.
Embodiment
As shown in Figure 1, a kind of screw of the present invention, is made up of No. 45 steel, the master gage of No. 45 steel is decided to be: tensile strength is 600MPa, and yield strength is 355MPa, and elongation percentage is 16%, reduction of cross sectional area is 40%, and ballistic work is 39J, uses No. 45 steel to make screw sturdy and durable.A kind of screw, comprise screw terminal 1 and lead screw 2, the cross section external frame of screw terminal 1 is regular hexagon, lead screw 2 is full flight screw, also comprises the cylindrical body pad 3 being arranged on screw terminal 1 the inner, and pad 3 and screw terminal 1 are formed in one structure, screw terminal 1 surface arranges cross or three-back-shaped groove 4, for with corresponding screw-driver with the use of, person easy to use takes off screw, improves working efficiency.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
Claims (2)
1. a screw, comprise screw terminal (1) and lead screw (2), the cross section external frame of screw terminal (1) is regular hexagon, lead screw (2) is full flight screw, it is characterized in that: also comprise and be arranged on the inner cylindrical body pad (3) of screw terminal (1), pad (3) and screw terminal (1) are formed in one structure, and described screw terminal (1) surface arranges cross groove (4); Described screw body is made up of No. 45 steel.
