Abstract
The invention relates to the technical field of fasteners, in particular to a screw rod. Most of the existing screw rods are solid cylindrical and only play a role in fastening, the solid materials are wasteful, and the fastening effect is not good. The screw rod comprises a screw rod body, wherein the screw rod body is internally hollow, is formed by at least two telescopic pipes and is provided with a criss cross reinforcing rib; locating holes are formed in two sides of the screw rod body and are interconnected. The improved screw rod is simple in structure, low in investment cost, material-saving, adjustable in length, and stable and firm in fastening.
Description
Technical field
The present invention relates to technical field of fastening, especially a kind of screw rod.
Background technique
Screw rod refers to that outer surface is cut spiral fluted cylinder or cut the circular cone of Conical Spiral Groove.Existing screw rod mostly is solid cylinder, just plays fastening effect, and solid material compares waste, and fastening effect neither be fine.
Summary of the invention
In order to overcome existing above-mentioned deficiency, the invention provides a kind of screw rod.
The technical solution adopted for the present invention to solve the technical problems is: a kind of screw rod, described screw body boring, and screw body is made up of at least two telescopic tubes, and screw body is provided with criss-crossing stiffening rib.
According to another embodiment of the invention, comprise described screw body both sides further and be provided with positioning hole, both sides positioning hole is through.
The invention has the beneficial effects as follows, structure is simple, and input cost is low, saves material, adjustable in length, fastening stablize firm.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is plan view of the present invention.
Fig. 2 is plan view of the present invention.
1. screw body, 2. telescopic tube, 3. stiffening rib, 4. positioning hole in figure.
Embodiment
As shown in Figure 1, 2, a kind of screw rod, comprises screw body 1, described screw body 1 boring, screw body 1 is made up of at least two telescopic tubes 2, flexible change spiro rod length, screw body 1 is provided with criss-crossing stiffening rib 3, although be hollow structure, intensity still will ensure, described screw body 1 both sides are provided with positioning hole 4, both sides positioning hole 4 is through, positioning screwn can be inserted from positioning hole 4 after fastening, the positioning hole 4 of both sides is through, can play the effect that secondary is fixing.
Screw-rod structure after improvement is simple, and input cost is low, saves material, adjustable in length, fastening stablize firm.
