Abstract
The invention discloses a screw capable of being disassembled manually. The screw comprises a screw body taking the shape of three steps; the screw body comprises a first connecting section, a second connecting section and a third connecting section, which are arranged from top to bottom; the diameters of the first connecting section, the second connecting section and the third connecting section are larger and larger; the cross section of the first connecting section is hexagonal; the cross section of the second connecting section and that of the third connecting section are circular; an external thread is arranged on the outer surface of the third connecting section; a threaded hole is formed in the upper end of the screw body and in the middle of the screw body; and the depth of the threaded hole spans the first connecting section and the second connecting section. The screw cooperates with a screw head and a hand-twisted screw cap, which are matched with the screw, to connect and tighten two parts together; all that is needed is to rotate the hand-twisted screw cap, the screw can be easily disassembled; and therefore, the screw is convenient to use, and can be popularized on a large scale.
Description
Technical field
The present invention relates to a kind of screw that can disassemble by hand, belong to Machine Components and Parts Design technical field.
Background technique
Screw, bolt connection piece have the features such as structure is simple, convenient disassembly, cost are low, apply very extensive.The fastening pieces such as a lot of screw, bolt also used by mould, but existing screw, bolt all must could be dismantled by special tool, the dismounting of whole mould is made to increase workload, therefore, be necessary that research and development one need by instrument, the screw that can directly disassemble by hand.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of screw that can disassemble by hand.
Technical solution of the present invention is achieved in that a kind of screw that can disassemble by hand, comprises screw body, described screw body be three grades stepped, be divided into the first linkage section, the second linkage section and the 3rd linkage section from top to bottom, and diameter is increasing; The cross section of described first linkage section is Hexagon; The cross section of described second linkage section and the 3rd linkage section is circle; The outer surface of described 3rd linkage section is provided with outside thread; Described screw body upper end also offers tapped hole; Described tapped hole is positioned in the middle part of screw body, its depth penetration first linkage section and the second linkage section.
Preferably, the Hexagon of the cross section of described first linkage section is inscribed within the second linkage section.
Preferably, the cross section of described first linkage section also can in the square being inscribed within the second linkage section.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The screw that can disassemble by hand of the present invention, structure is simple, reasonable in design, coordinate the screw terminal that matches with it and hand tighten screw cap to be connected by two parts to tighten together, during dismounting, as long as firmly rotate hand tighten screw cap just can easily screw disassembling be got off, easy to use, can promote on a large scale.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is structural representation of the present invention;
Structural representation when accompanying drawing 2 is screw of the present invention uses.
In figure: 1, the first linkage section; 2, the second linkage section; 3, the 3rd linkage section; 4, tapped hole; 5, hand tighten screw cap; 6, screw terminal; 7, part one; 8, part two.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
The screw that can disassemble by hand of the present invention, as shown in accompanying drawing 1,2, comprises screw body, described screw body be three grades stepped, be divided into the first linkage section 1, second linkage section 2 and the 3rd linkage section 3 from top to bottom, and diameter is increasing; The cross section of described first linkage section 1 is Hexagon; The cross section of described second linkage section 2 and the 3rd linkage section 3 is circle; The outer surface of described 3rd linkage section 3 is provided with outside thread; Described screw body upper end also offers tapped hole 4; Described tapped hole 4 is positioned in the middle part of screw body, its depth penetration first linkage section 1 and second linkage section 2; The Hexagon of the cross section of described first linkage section is inscribed within the second linkage section.
Screw of the present invention, coordinate the screw terminal 6 that matches with it and hand tighten screw cap 5 to be connected by two parts to tighten together, as shown in Figure 2, 3rd linkage section 3 of screw is threaded with part 1, part 28 is set in outside the second linkage section 2, 3rd linkage section just exposes the upper-end surface of part 28, hand tighten screw cap 5 is enclosed within outside the first linkage section, the lower end surface of hand tighten screw cap 5 offers the hexagonal hole matched with the first linkage section, finally the intermediate throughholes that screw terminal 6 passes hand tighten screw cap 5 is threaded in the tapped hole 4 of screw, tightening the screw head 6 is fixed by hand tighten screw cap 5 and screw of the present invention, when needing to disassemble, only need to turn on hand tighten screw cap 5 by hand, drive screw just screw can be dismantled from part 1.The screw that can disassemble by hand of the present invention, structure is simple, reasonable in design, easy to use, can promote on a large scale.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
