Description
Technical field
The utility model relates to fastening parts of automobiles design field, specially a kind of novel interior hexagonal flower-shape screw.
Background technique
Currently, the fastening of auto parts and components generally selects screw as fastener, but using screw to auto parts and components into
There are following problems often in row fastening:
1) outer diameter of screw rod is consistent with installation bore dia, and screw rod is difficult to quick insertion into mounting hole, leads to working efficiency
It is low；
2) nut is easy to scratch part mounting surface when installing, and causes the surface treatment of mounting surface to be destroyed and rustization occurs
Corrosion；
3) head diameter is less than normal, and installation rear nut can not cover mounting hole completely, causes leakproofness poor；
4) screw fastener hole is single, can only correspond to a kind of fastening tool, poor universality.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of novel interior hexagonal flower-shape spiral shell
Nail, solve existing screw screw rod be difficult to quick insertion into mounting hole, the surface treatment of mounting surface be easily destroyed appearance
The problem of rustization burn into head diameter is less than normal, and nut can not cover mounting hole completely, leakproofness difference and poor universality.
To achieve the goals above, the technical solution adopted in the utility model are as follows:
A kind of novel interior hexagonal flower-shape screw, including screw rod, nut and plastic spacer, the nut and screw rod one at
Type is in one end of the screw rod；The end of the screw rod other end and screw rod are integrally formed with a guide frame；The guiding
The end face diameter of structure is less than the diameter of the screw rod；The nut is flange disk-like structure；The nut upper surface and nut
Integrally formed with a boss；A screw fastener hole is offered on the boss；The screw fastener hole has three layers of pass
Structure, first layer pass be hexagonal flower-shape hole, the second layer be with the matched hexagonal hole of allen wrench, third layer is bottom
For the conical bore of " cross " shape.
Further, the nut with a thickness of 4mm-6mm.
Further, the outer diameter of the plastic spacer is equal with the diameter of the nut.
Further, the internal diameter of the plastic spacer is equal with the diameter of the screw rod.
The novel interior hexagonal flower-shape screw can enable screw easily just insert by the guide frame of screw rod end
Enter in mounting hole, facilitates installation；By plastic spacer, protection can be played to the surface treatment of mounting surface when screw is installed and tightened
Effect prevents metal nut to be directly surface-treated with mounting surface contact failure, plays a protective role to mounting surface；Nut is made into
Flange-shaped Parts have certain thickness, and integral diameter increases, and nut can cover mounting hole, good seal performance completely；Screw fastener hole
Three layers of pore structure are made into, can be allowed to be suitable for different dismantling devices, the versatility of product is high.
The utility model structure is simple, easy for installation, and when installation is applicable to different tools and it is tightened or is twisted
Pine and mounting surface, the good seal performance after installation will not be damaged.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial sectional view at the utility model screw fastener hole；
Fig. 3 is the top view of the utility model；
In figure: 1, screw rod, 2, nut, 3, plastic spacer, 4, guide frame, 5, boss, 6, screw fastener hole.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
The novel interior hexagonal flower-shape screw of one kind as shown in Figs. 1-3, including screw rod 1, nut 2 and plastic spacer 3, it is described
Nut 2 and screw rod 1 are shaped in one end of the screw rod 1；The end of 1 other end of screw rod and screw rod 1 integrally formed with
One guide frame 4；The end face diameter of the guide frame 4 is less than the diameter of the screw rod 1；The nut 2 is flange plate-like
Structure；2 upper surface of nut and nut 2 are integrally formed with a boss 5；A screw fastening is offered on the boss 5
Hole 6；The screw fastener hole 6 has three layers of pass structure, and first layer pass is hexagonal flower-shape hole, and the second layer is to pull with interior hexagonal
The matched hexagonal hole of hand, third layer are the conical bore that bottom is " cross " shape.
Preferably, the nut 2 with a thickness of 4mm-6mm；The diameter of the outer diameter of the plastic spacer 3 and the nut 2
It is equal；The internal diameter of the plastic spacer 3 is equal with the diameter of the screw rod 1.
It, can by the guide frame 4 of 1 end of screw rod when the novel interior hexagonal flower-shape screw fastens body part
So that screw is easily inserted into mounting hole, facilitates installation；It, can be when screw be installed and is tightened to peace by plastic spacer 3
The surface treatment in dress face plays a protective role, and prevents metal nut 2 to be directly surface-treated with mounting surface contact failure, to mounting surface
It plays a protective role；Nut 2 is made into Flange-shaped Parts with certain thickness, integral diameter increases, and nut 2 can cover installation completely
Hole, good seal performance；Screw fastener hole 6 is made into three layers of pore structure, and the hexagonal flower-shape pore structure of first layer is applicable to " word "
Screwdriver plays fastening effect to screw, and the regular hexagon pore structure of the second layer is applicable to allen wrench and plays to screw
Fastening effect, the bottom of third layer are the conical bore of " cross " shape, are applicable to " cross " screwdriver and play fastening work to screw
With versatility is good.
The utility model structure is simple, easy for installation, and when installation is applicable to different tools and it is tightened or is twisted
Pine and mounting surface, the good seal performance after installation will not be damaged.
Above embodiment is the explanation to the utility model, is not the restriction to the utility model, it is possible to understand that not
These embodiments can be carried out with a variety of variations, modification, replacement in the case where being detached from the principles of the present invention and spirit and become
Type, the protection scope of the utility model are defined by the appended claims and the equivalents thereof.
