And other items on be all essential accessory.It is existing but the screw selection for some specific positions has special requirement
Standard screws can not meet needs, existing screw lacks closing function for nail caused by its installation, is likely to result in
Leakage problem.
Utility model content
The purpose of this utility model is in place of overcome the deficiencies in the prior art, there is provided one kind positioning is simple and reliable, applicable
Property multifunctional bolt wide, easy to operate.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of multifunctional bolt, including the head of a nail, stopper slot, screw rod and screw thread, coaxially it is formed with axial one end of screw rod
The head of a nail, the diameter of the head of a nail are more than screw rod, stopper slot are formed with the middle part of the axial outer end of the head of a nail, it is characterised in that：It is connected with screw rod
Head of a nail axial end excircle is formed with a bulge loop, and the middle shaft section of the bulge loop is triangular pyramidal, and the bulge loop can be embedded in installation end
Face, form outer layer sealing ring.
Moreover, the link position of screw rod and the head of a nail is formed with, annular chamfer is domatic, and the annular chamfer is domatic can be embedded in installation
The nail end of end face, form internal layer sealing.
Moreover, being arranged at intervals with two groups of screw threads on the screw rod, the screw rod between two groups of screw threads is polished rod.
Moreover, it is formed with stopper slot in the middle part of the axial other end of screw rod.
The advantages of the utility model and good effect are：
The utility model is simple in construction, cost is cheap, is improved by structure and realizes its special function, can effectively close spiral shell
There is certain flexible material connection to use for hole gap caused by nail, such as timber that is particularly suitable for use in, and can be in sky
Between it is narrow and small when assembled, applicability is wide.
Brief description of the drawings
Fig. 1 is structure sectional view of the present utility model；
Fig. 2 is schematic appearance of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, and following examples are simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
A kind of multifunctional bolt, for convenience of description the present embodiment illustrated with direction shown in accompanying drawing 1, including the head of a nail 1,
Stopper slot 6, screw rod 5 and screw thread 4, the head of a nail is coaxially formed with axial one end of screw rod, the diameter of the head of a nail is more than screw rod, the head of a nail
Stopper slot is formed with the middle part of axial outer end, is used when being easy to using screwdriver installation；
Innovative point of the present utility model is：
Two groups of screw threads 4 are arranged at intervals with the screw rod, the screw rod between two groups of screw threads is polished rod, ensures stable connection
Manufacturing cost is saved while property；
The head of a nail axial end excircle being connected with screw rod is formed with a bulge loop 2, and the middle shaft section of the bulge loop is triangular pyramidal,
The complete tightening of screw in place when, in the mounted end face of bulge loop insertion, form effective outer layer sealing ring.
The link position of screw rod and the head of a nail is formed with annular chamfer domatic 3, the nail of the domatic embedded installation end face of the annular chamfer
Bore ends, form internal layer sealing.
For the ease of being formed with stopper slot 6 in the middle part of special position installation, the axial other end of screw rod, it can be used for screwdriver
Installation force.
