Description
Technical field
The present invention relates to screw field, particularly relate to a kind of double-threaded screw.
Background technology
Existing screw is varied, of a great variety, cap nut has hexagonal, has interior hexagonal, also cross
Flower-shape, there is flat mouth in-line, loading and unloading various types of screw needs different corresponding handling instruments, and this just requires in family
Or service worker has various instrument, if handling instrument is not suitable for, it is difficult to corresponding screw is loaded and unloaded, uses at needs
Screw must be changed during wood screw.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of double-threaded screw, and it is reasonable in design, and simple in construction solves
The problem that existing screw is difficult to installation and removal.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is to provide a kind of double-threaded screw, comprising:
Cross recess, head of tightening up a screw, lower screw terminal and screw rod；Described cross recess is positioned at the upper surface of head of tightening up a screw；Described head of tightening up a screw
Lower surface is connected with lower screw terminal；The lower surface of described lower screw terminal arranges a screw rod；Described screw rod is provided with screw thread；Described spiral shell
The lower end of bar is provided with a through hole；This double-threaded screw described is an overall structure.
Preferably, described cross recess indent is on head of tightening up a screw；
Preferably, the length of side of head is tightened up a screw described in less than the length of side of lower screw terminal.
The invention has the beneficial effects as follows: present configuration is simple, reasonable in design that there is good manufacturability and enough strong
Spend, and screw terminal has large and small two kinds of types, and be additionally provided with cross recess on head of tightening up a screw, when dismantling and install, it is not necessary to look for specific
Spanner, it is simple to workman mounts and dismounts, and can be greatly saved the time of staff, improves work efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of double-threaded screw of the present invention；
In accompanying drawing, the labelling of each parts is as follows: 1, cross recess；2, tighten up a screw head；3, lower screw terminal；4, screw rod；5, through hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to accompanying drawing 1, the embodiment of the present invention includes: cross recess 1, tighten up a screw 2, lower screw terminal 3 and a screw rod 4；Described
Cross recess 1 be positioned at tighten up a screw 2 upper surface；Described tighten up a screw 2 lower surface be connected with lower screw terminal 3；Described lower screw
The lower surface of 3 arranges a screw rod 4；Described screw rod 4 is provided with screw thread；The lower end of described screw rod 4 is provided with a through hole 5；Described should
Double-threaded screw is an overall structure.
Further, described cross recess 1 indent is in 2 upper surface of tightening up a screw；
Further, tighten up a screw described in 2 the length of side less than the length of side of lower screw terminal 3.
When workman mounts and dismounts, it is not necessary to prepare specific spanner, described cross recess 1 is easy to use screwdriver and installs
And dismounting；Upper and lower screw terminal is easy to use the spanner of different model and mounts and dismounts it；When nut is screwed on screw rod 4
Time, nut landing can be prevented with iron wire through through hole 5.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology necks
Territory, is the most in like manner included in the scope of patent protection of the present invention.
Claims (3)
1. a double-threaded screw, it is characterised in that including: cross recess, head of tightening up a screw, lower screw terminal and screw rod；Described cross recess position
