Abstract
The invention discloses a special-shaped screw which comprises a screw nut, a screw rod, a dent, a stud and a groove. The stud comprises an upper end face and a lower end face. The screw rod is in a cylindrical shape, wherein one end of the screw rod is connected to the lower end face of the screw nut, the other end of the screw rod is connected with the stud, and the screw rod is used for bearing the screw nut and the stud. The dent is located in the lower end of the screw rod, and the dent and the screw rod are in a two-stage step shape. The special-shaped screw is simple in structure, convenient to use, low in manufacturing cost, easy to machine, small in occupied space and convenient for people to machine and use.
Description
Technical field
The present invention relates to screwed lock firmware field, particularly relate to a kind of abnormity screw.
Background technology
On circuit board, some components and parts needs to be fixed with screw, such as central processing unit fixture on computer motherboard and radiator etc..Screw belongs to a kind of locking part, can cooperate and use with screw, so that various parts to be combined into an assembly, and can make the easy assembly and disassembly of part.General screw mainly include a blind nut, the intermediate being connected with this blind nut and can with screw the relative threaded rod combined.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of abnormity screw, and it is reasonable in design, simple in construction, solves the problem being in use difficult to install.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is to provide a kind of abnormity screw, comprising: blind nut, screw rod, chase, stud and groove；Described stud includes upper surface and lower surface；Described screw rod is cylindric, and one end is connected to the lower surface of described blind nut, and the other end is connected with described stud, is used for accepting described blind nut and described stud；Described chase is positioned at screw rod lower end；Described chase and screw rod be two grades stepped；Described stud head is taper.
Preferably, the outer surface of described stud is screw-like；
Preferably, described blind nut upper surface is plane；
Preferably, described upper surface is provided with groove；
Preferably, described groove is cross groove；
Preferably, the diameter of described screw rod is less than the diameter of blind nut, and the diameter of described stud is less than the diameter of screw rod.
The invention has the beneficial effects as follows: this apparatus structure rationally and has enough intensity and good manufacturability, simple in construction simultaneously, and processing cost is low, it is simple to people use.
Accompanying drawing explanation
Fig. 1 is the front view of the present invention a kind of abnormity screw；
Fig. 2 is the axonometric chart of the present invention a kind of abnormity screw；
In accompanying drawing, the labelling of each parts is as follows: 1, blind nut；11, upper surface；12, lower surface；2, screw rod；3, chase；4, stud；5, groove.
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 can be 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 and Fig. 2, the embodiment of the present invention includes: blind nut 1, screw rod 2, chase 3, stud 4 and groove 5；Described stud 4 includes upper surface 11 and lower surface 12；Described screw rod 2 is cylindric, and one end is connected to the lower surface 12 of described blind nut 1, and the other end is connected with described stud 4, is used for accepting described blind nut 1 and described stud 4；Described chase 3 is positioned at screw rod 2 lower end；Described chase 3 and screw rod 2 are stepped in two grades；Described stud 4 head is taper.The outer surface of described stud is screw-like；Described blind nut upper surface is plane；It is provided with groove on described upper surface；Described groove is cross groove；The diameter of described screw rod is less than the diameter of blind nut, and the diameter of described stud is less than the diameter of screw rod.
Described blind nut 1 upper surface 11 is provided with cross groove, can make screwdriver and cross groove perfect cooperation, and preventing in work is to skid.Described screw rod 2 is provided with chase 3 near one end of described stud 4, for some latch closures carry out with the use of, zero firmware is fixed.The outer surface of described stud 4 is screw-like, for being connected with the screw on part.The diameter of described blind nut 1, screw rod 2 and spiral shell 4 post is stepped and gradually decreases.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
