Abstract
The invention relates to an antitheft bolt. The antitheft bolt includes a bolt head and a screw rod; the bolt head is inserted into the screw rod through a connection device; the screw rod is provided with outer threads; the bolt head is provided with a polygonal occlusion tooth projecting upward; the center of the occlusion tooth is circular; the circular outer periphery of the occlusion tooth is provided with five projections which are flower-shaped; the connection device is cross-shaped; and a cross-shaped groove matching the shape of the connection device is arranged in the screw rod. The advantages of the antitheft bolt are that the bolt head and the screw rod can be connected or disconnected through the connection device; the bolt can be conveniently screwed or released; it is ensured that a surface of an article to be fixed is flat; and the polygonal occlusion tooth of the bolt head can used by means of a special wrench matching the shape of the polygonal occlusion tooth, and then the theft rate can be decreased.
Description
Technical field
The present invention relates to a kind of bolt, particularly relate to a kind of anti-theft bolt, belong to standard component system
Make field.
Background technology
Bolt is commonly used securing member in daily life, and general bolt head can be provided with hexagonal
Shape or cross groove, it is possible to use proper implements is embedded into bolt in these grooves
Tighten or unscrew, owing to hex-shaped recess or cruciform groove are relatively common, because
Give robber chance, and typically all protrude from the surface of fixation due to bolt head,
Cause the out-of-flatness on surface.Therefore, it should provide a kind of new technical scheme to solve the problems referred to above.
Content of the invention
It is an object of the invention to: a kind of anti-theft bolt is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of anti-theft bolt, bag
Including bolt head and screw rod, bolt head is plugged in screw rod by attachment means, outside screw rod is provided with
Screw thread, bolt head is provided with the polygon tooth engaged raising up.
The middle part of tooth engaged is circle, and the circular periphery of tooth engaged is provided with five projections, in flower
Shape.
Attachment means presents cross, is provided with the cross with attachment means form fit in screw rod
Groove.
Due to the application of technique scheme, the present invention compared with prior art has excellent as follows
Point: bolt head and screw rod can be attached by attachment means or separately, both can facilitate
Bolt is tightened or unclamps, it can also be ensured that the surface of fixation smooth；On bolt head
Polygon tooth engaged, need to use by the special key of form fit therewith, reduce
Antitheft rate.
Brief description
Accompanying drawing 1 is the embodiment of the present invention one structural representation.
The top view that accompanying drawing 2 is the embodiment of the present invention one.
The top view of the screw rod that accompanying drawing 3 is the embodiment of the present invention one.
In the figures above: 1-bolt head, 2-screw rod, 3-attachment means, 4-external screw thread, 5-
Tooth engaged, 6-is protruding, 7-cross groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Embodiment one:
As shown in Figure 1 to Figure 3, a kind of anti-theft bolt of the present invention, including bolt head 1 and screw rod 2,
Bolt head 1 is plugged in screw rod 2 by attachment means 3, and screw rod 2 is provided with external screw thread 4, bolt
1 is provided with the polygon tooth engaged 5 raising up.
The middle part of tooth engaged 5 is circle, and the periphery of tooth engaged 5 circle is provided with five projections 6,
In flower-shape.
Attachment means 3 presents cross, is provided with ten with attachment means 3 form fit in screw rod 2
Font groove 7.
Bolt head 1 and screw rod 2 can be attached by attachment means 3 or separate, both can be square
Just bolt tightened or unclamp, it can also be ensured that the surface of fixation smooth；Bolt head 1
On polygon tooth engaged 5, need to use by the special key of form fit therewith, subtract
Lack antitheft rate.
Above-described embodiment is only that the technology that the present invention be described is conceived and feature, its object is to allow ripe
The personage knowing technique will appreciate that present disclosure and implements according to this, can not limit with this
Protection scope of the present invention processed.All equivalences made according to spirit of the invention change or repair
Decorations, all should cover within protection scope of the present invention.
