Abstract
The utility model relates to an anti-theft locking fastening part which is adequate for anti-theft locking of outdoor equipments and consists of a bolt, a nut, a spring washer and a flat spacer, wherein a retaining nest is arranged on the bolt of the fastening piece; the ratchet nut is structured by a convex stand with inclined plane which is arranged on the lower surface of the nut; a convex stand which corresponds to the retaining nest on the bolt and can slide in the retaining nest is arranged inside the spring washer; and when the fastening piece is assembled, the ratchet structure is structured by a pawl which is formed on the opening end of the spring washer and the ratchet nut both of which match with each other. The utility model can make the nut be screwed down and cannot be disassembled freely, thereby the effects of anti-theft and locking are achieved.
Description
The utility model relates to a kind of fastening piece, is specially adapted to the antitheft locking of outdoor equipment.
The bolt fastener that uses is easy to dismounting after tightening at present, and this antitheft locking problem to outdoor equipment can't solve.
The purpose of this utility model is the shortcoming that overcomes existing bolt fastener, and a kind of antitheft fastener that can't freely dismantle behind the nut screwing clamping that makes is provided, and plays antitheft and locking effect.
The technical solution of the utility model is achieved in that a kind of antitheft fastener is by bolt, nut, spring washer, flat gasket is formed, its special way is, on bolt, have locating slot, the lower surface of nut has the boss on band inclined-plane to constitute the nut of ratchet structure, spring washer inside have with bolt on the corresponding boss of locating slot can in locating slot, slide, when nut and spring washer, flat gasket is assembled in and constitutes fastening piece on the bolt, the open end formation ratchet of spring washer and ratchet nut match and contain the formation ratchet mechanism, nut can only be tightened in the clockwise direction rotation, can not dismantle arbitrarily by the restriction of ratchet and reverse when dismantling nut, prevent stolen.
The utility model advantage compared with prior art is when utilizing this fastening piece fixed equipment, can't freely dismantle behind the nut screwing clamping, plays antitheft locking effect.
Now describe the utility model most preferred embodiment in detail in conjunction with example.
Fig. 1 is the structural representation of antitheft fastener
Fig. 2 is the bolt arrangement schematic representation
Fig. 3 is the worm's eye view of nut
Fig. 4 is the plan view of spring washer
Among the figure: 1. locating slot 5. spring washers
2. bolt 6. flat gaskets
3. nut 7. boss
