Description
Technical field
This utility model relates to a kind of screw with protection mechanism.
Background technology
Screw and bolt are the most frequently used securing members, and it is with its low price, easy to use and be widely used.At present,
The screw major part sold on market is to arrange cross recess or a word groove on head of screw, although this structure is simple,
But there are the fixing article in outdoor easily to be unclamped by screw with common screwdriver by thief and stolen.Moreover, screw
Screw head is the most naked to be exposed on the external, and easily produces damage, is unfavorable for the dismounting in later stage.
Summary of the invention
In place of above-mentioned the deficiencies in the prior art, the problem that this utility model solves is: the screw head of screw is the most exposed
In outside, easily produce damage, be unfavorable for the dismounting in later stage.
For solving the problems referred to above, the technical scheme that this utility model is taked is as follows:
A kind of screw with protection mechanism, including spiral shell body, screw head and protection set；Described spiral shell body is cylindrical structural；
Described spiral shell body one end is provided with the conehead of pyramidal structure；The described spiral shell body other end and screw head are fixed；Described screw head is flat body
Cylindrical structural；The lateral surface of described screw head is provided with swivelling chute；The surrounding side of described screw head is provided with external screw thread；Institute
The cross section of the protection set stated takes the shape of the letter U structure；Described protection set medial wall is provided with female thread；Described protection set is by interior spiral shell
The external screw thread of stricture of vagina and screw head is rotatably connected.
Further, described swivelling chute is in-line.
Further, described swivelling chute is cross.
Further, described protection set is made up of aluminum.
The beneficial effects of the utility model
This utility model is additionally arranged protection set, arranges external screw thread on the surrounding side of screw head, and the cross section of protection set takes the shape of the letter U
Structure, arranges female thread on protection set medial wall, and protection set is rotated by the external screw thread of female thread and screw head and links together.
This utility model can prevent the infringement of screw head by this protection screw head of protection set.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is fractionation structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model content is described in further detail.
As it is shown in figure 1, a kind of screw with protection mechanism, including spiral shell body 1, screw head 2 and protection set 3.Described spiral shell body 1
In cylindrical structural.Described spiral shell body 1 one end is provided with the conehead 11 of pyramidal structure.Described spiral shell body 1 other end and screw head 2 are solid
Fixed.Described screw head 2 is in flat body cylindrical structural.The lateral surface of described screw head 2 is provided with swivelling chute 21.As in figure 2 it is shown, institute
The surrounding side of the screw head 2 stated is provided with external screw thread 22.The cross section of described protection set 3 takes the shape of the letter U structure.Described protection set 3
Medial wall is provided with female thread 31.Described protection set 3 is rotatably connected by the external screw thread 22 of female thread 31 and screw head 2.Enter one
Preferably, described swivelling chute 21 is in in-line or in cross for step.Further preferably, described protection set 3 is by aluminum system
Become.
This utility model is additionally arranged protection set 3, arranges external screw thread 22, the cross section of protection set 3 on the surrounding side of screw head 2
Take the shape of the letter U structure, arranges female thread 31 on protection set 3 medial walls, and protection set 3 is by female thread 31 and the external screw thread 22 of screw head 2
It is rotatably connected together.This utility model can prevent the infringement of screw head 2 by this protection screw head 2 of protection set 3.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
