Abstract
The invention discloses a hand-twisted screw cap. The hand-twisted screw cap comprises a screw cap body, wherein the screw cap body is cylindrical; the upper end face of the screw cap body is provided with a round counter bore; the lower end face of the screw cap body is provided with a hexagonal counter bore; the round counter bore is communicated with the hexagonal counter bore by a round through hole; the central axis of the round counter bore, the central axis of the round through hole and the central axis of the hexagonal counter bore are the central axis of the screw cap body. The hand-twisted screw cap disclosed by the invention can be used for connecting and fastening two parts together by being matched with a screw head and a screw; during dismounting, an operator can easily dismount one of the parts by just rotating the hand-twisted screw cap with a hand; the hand-twisted screw cap is convenient to use and applicable to wide-range popularization.
Description
Technical field
The present invention relates to a kind of hand tighten screw cap, 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 hand tighten screw cap.
Technical solution of the present invention is achieved in that a kind of hand tighten screw cap, comprises screw cap body, and described screw cap body is cylindrical shape; The upper-end surface of described screw cap body is provided with circular counter sink, and its lower end surface is provided with hexagon counter sink; Described circular counter sink is communicated with by manhole with hexagon counter sink; The central shaft of described circular counter sink, manhole and hexagon counter sink is the central shaft of screw cap body.
Preferably, described screw cap body is two stage steps shape cylindrical body, and one end external diameter near circular counter sink is greater than the external diameter of the other end.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Hand tighten screw cap of the present invention, coordinate the screw terminal that matches with it and screw to be connected by two parts to tighten together, during dismounting, as long as one of them part just can disassemble by manual effort rotation hand tighten screw cap easily, 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 hand tighten screw cap of the present invention uses.
In figure: 1, screw cap body; 2, circular counter sink; 3, hexagon counter sink; 4, manhole; 5, screw; 6, screw terminal; 7, part one; 8, part two.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Hand tighten screw cap of the present invention, as shown in accompanying drawing 1,2, comprises screw cap body 1, and described screw cap body 1 is in cylindrical shape; The upper-end surface of described screw cap body 1 is provided with circular counter sink 2, and its lower end surface is provided with hexagon counter sink 3; Described circular counter sink 2 is communicated with by manhole 4 with hexagon counter sink 3; The central shaft of described circular counter sink 1, manhole 4 and hexagon counter sink 3 is the central shaft of screw cap body 1; Described screw cap body 1 is in two stage steps shape cylindrical body, and one end external diameter near circular counter sink 2 is greater than the external diameter of the other end.
Screw of the present invention, coordinate the screw 5 that matches with it and screw 6 to be connected by two parts to tighten together, as shown in Figure 2, the lower end of screw is threaded with part 1, part 28 to be set in the middle part of screw on excircle, the part that part 28 is exposed in upper end is just hexagonal one end, the hexagon counter sink 3 of hand tighten screw cap is enclosed within the upper end of screw, finally be threaded in the tapped hole 4 of screw by the intermediate throughholes that screw terminal 6 passes hand tighten screw cap, tightening the screw head 6 is fixed by hand tighten screw cap of the present invention and screw; When needing to disassemble, only need to turn on hand tighten screw cap of the present invention by hand, drive screw just screw can be dismantled from part one.Hand tighten screw cap 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.
