Description
One, affiliated technical field
The utility model relates to anti-theft bolt, belongs to outdoor equipment and auto parts machinery field.
Two, background technique
At present, the stolen incident of vapour vehicle tire happens occasionally, in case stolenly just bring many unnecessary troubles to the car owner, this situation all took place in the large-scale valuable equipment of system's settings such as the transformer that some outdoor equipment such as electric industry department are provided with, the pump motor of waterpower department and railway, harbour, at the stolen situation of vapour vehicle tire, I have applied for two patents (application number 200920021828X, 2009200218275), but hypesthesia face, non-system.
Three, summary of the invention
The purpose of this utility model provides a kind ofly has only socket wrench specially adapted for it just can unload bolt, can prevent the anti-theft bolt that outdoor equipment and automobile tire are stolen.
Technical solution of the present utility model is as follows:
Anti-theft bolt is characterized in that this anti-theft bolt 1 is polygonal shape, and the limit of anti-theft bolt is provided with protuberance 2.
The limit of the utility model bolt is provided with together, the above protuberance in two roads or two roads, and protuberance can be located at the arbitrary position on the limit, and the spacing of protuberance can be set arbitrarily, increases the permutation and combination quantity of bolt.
The utility model is equipped with socket wrench specially adapted for it, and a shape is equipped with a socket wrench specially adapted for it, and non-socket wrench specially adapted for it can unload any more bolt.
When under non-countersunk screw situation, using,, can steal bolt peripheral hardware stealingproof sleeve for other instruments such as defence use pipe wrench unload bolt, the height of stealingproof sleeve and the consistency of thickness of bolt, other instrument is used in restriction, has only socket wrench specially adapted for it just can open.
The said bolt of the utility model refers to nut or bolt.
The utility model has only and has special tool in person, and do not match worker's tool of stranger can't be opened.This bolt profile is ever-changing, varied, and anti-theft is good, and is easy to use, cost is low.
Four, description of drawings
Fig. 1: be the utility model Hexagon bolt schematic representation.
Fig. 2: be the utility model Octagon bolt schematic representation.
Fig. 3: be the utility model multiple tracks protuberance schematic representation.
Fig. 4: be the utility model stealingproof sleeve schematic representation.
Each parts comprises among the figure: 1 bolt, 2 protuberances, 3 stealingproof sleeves.
Five, embodiment
Embodiment one: with reference to Fig. 1 is the Hexagon anti-theft bolt, and the limit of bolt is provided with protuberance one, and protuberance can be located at the arbitrary position on the limit.
Embodiment two: with reference to Fig. 2 is the Octagon anti-theft bolt, and the limit of bolt is provided with protuberance one, and protuberance can be located at the arbitrary position on the limit.
Embodiment three: is multiple tracks protuberance anti-theft bolt with reference to Fig. 3, the limit of bolt is provided with the above protuberance in two roads or two roads, and protuberance can be located at the arbitrary position on the limit, and the spacing of protuberance can be set arbitrarily, increases the permutation and combination quantity of bolt.
When the utility model uses under non-countersunk screw situation, when just bolt exposes, can establish stealingproof sleeve 3, stealingproof sleeve is enclosed within on the bolt, the thickness basically identical of the height of stealingproof sleeve and bolt, its effect can not directly act on bolt when being to use other instrument demounting bolt, and non-use socket wrench specially adapted for it can not unload bolt.
