Description
Technical field
This utility model relates to a kind of bolt, particularly to a kind of anti-theft bolt.
Background technology
Bolt is a kind of conventional active connection, and when screw head is circular, screw head top is provided with yi word pattern, cross
Etc. standard flute, corresponding instrument such as the word bottle opener using standard is just rotatable, and simple in construction facilitates, and extensively applies
In various industries, but this also result in some valuable assembly such as power equipments etc. using this kind of bolt to assemble and is readily disassembled, and holds
Subject to steal.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provide a kind of simple in construction, have certain anti-theft feature,
The anti-theft bolt that proprietary instrument rotates need to be used.
This utility model solves its technical problem and be the technical scheme is that
A kind of anti-theft bolt, including screw head and screw rod, described screw head is smooth circle, the top section of described screw head to
Lower recess forms depressed part, and described depressed part is provided with the lobe raised up, and described depressed part is provided with at least one and supports
Retaining groove.
The top of described lobe is concordant with the top of described screw head.
The top of described lobe is less than the top of described screw head.
Described depressed part is pentalpha, and described withstanding grooves has five and lays respectively at five angles of described depressed part.
Described depressed part is positive pentalpha, and described boss is in the center of described depressed part.
The end of described withstanding grooves is provided with fillet.
The beneficial effects of the utility model are: screw head of the present utility model is smooth circle, it is possible to avoid nipper
As screw head clamped by adjustable wrench etc., playing ground floor anti-theft function, depressed part is formed on the top of screw head, and depressed part is provided with projection
Portion and at least one withstanding grooves, lobe plays and prevents all kinds of tablet such as word bottle opener to be directly inserted into withstanding grooves, plays
Two layers of anti-theft function, need to use the instrument adapted with described depressed part, lobe and withstanding grooves to rotate, simple in construction,
It is prone to processing, good anti-theft effect.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of anti-theft bolt, including screw head 1 and screw rod 2, described screw head 1 is smooth circle, it is possible to avoid
Screw head clamped by nipper such as adjustable wrench etc., plays ground floor anti-theft function；The top section concave downward shape of described screw head 1
Be in depression portion 3, and described depressed part 3 is provided with the lobe 4 raised up, and described depressed part 3 is provided with at least one withstanding grooves
5, lobe plays and prevents all kinds of tablet such as word bottle opener to be directly inserted into withstanding grooves 5, plays second layer anti-theft function, need to adopt
Could rotate with the instrument adapted with described depressed part, lobe and withstanding grooves；In the present embodiment, described lobe 4
Top is concordant with the top of described screw head 1, or the top of described lobe 4 is less than the top of described screw head 1, described depressed part
3 in pentalpha, and described withstanding grooves 5 has five and lays respectively at five angles of described depressed part 3, the depressed part of pentalpha
The further complicated shape of depressed part so that general instrument cannot insert in withstanding grooves 5, plays third layer anti-theft function；
Described depressed part 3 is in positive pentalpha, and described lobe 4 is positioned at the center of described depressed part 3, the end of the most described withstanding grooves 5
It is provided with fillet 6, simple in construction, it is easy to processing, reduces the manufacturing cost of this kind of anti-theft bolt.
