Abstract
The utility model relates to an anti-theft fastening mechanism. The anti-theft fastening mechanism comprises a ratchet wheel which is installed in the radial direction of a bolt, a pawl which can clamp the ratchet wheel is arranged on the side of the ratchet wheel, and one side of the pawl is provided with an anti-theft lock which can push away the ratchet wheel and enables the pawl to be detached from the ratchet wheel. The fastening mechanism controls the bolt to rotate through the anti-theft lock so as to enable the bolt to be controlled in fastening or loosening, and improves anti-theft level, and is good in anti-theft effect.
Description
Technical field
The utility model belongs to equipment unit tightening technology field, especially a kind of retention mechanism, especially a kind of antitheft retention mechanism that is applied to screw bolt and nut.
Background technique
The screw bolt and nut combination is used for being fastenedly connected two with the part of through hole, extensive use in productive life.In the prior art, many fastening parts of bolt and nut of using lack anti-theft measure owing to lacking bolt and nut spare, can illegally be dismantled, and cause losing of secure component, cause the tremendous economic loss.Although occurred the theftproof bolt nut of some special constructions in the prior art, these theftproof bolt nuts must use the profile spanner special tool to use.But the most of annex for equipment needs often to change, repair and maintenance, and existing antitheft non-disconnectable fastening piece can not satisfy the repair and replacement demand; And special tool is easily copied, and antitheft rank is lower.Thereby need the higher equipment of a kind of antitheft removable and antitheft rank to satisfy this demand.The purpose of this utility model is to overcome the above problems preferably, by the rotation of burglarproof lock control bolt, so that bolton or unclamp has controlledly improved antitheft rank, good anti-theft effect.
The model utility content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of antitheft retention mechanism is provided, and this retention mechanism is by the rotation of burglarproof lock control bolt, so that bolton or unclamp has controlledly improved antitheft rank, good anti-theft effect.
The purpose of this utility model solves by the following technical programs:
This antitheft retention mechanism comprises being installed on the ratchet that bolt directly makes progress, and is provided with the ratchet that can block ratchet at the side of described ratchet, and a side of described ratchet is provided with can be pushed ratchet open and make it break away from the burglarproof lock of ratchet.
The lower end of above-mentioned ratchet is fixed by rotating shaft, and is provided with Returnning spring between described ratchet and the rotating shaft.
The dead bolt of above-mentioned burglarproof lock is close to described ratchet one side setting, and described dead bolt relies on the described ratchet of rotation promotion to overcome Returnning spring disengaging ratchet.
Above-mentioned bolt, ratchet, ratchet and burglarproof lock all are fixedly installed in the housing; The unlocking port of described burglarproof lock is arranged on the housing.
Antitheft retention mechanism of the present utility model is by the rotation of burglarproof lock control bolt, so that bolton or unclamp has controlledly improved antitheft rank, good anti-theft effect.This mechanism can be widely used in facility, field facility, the city lighting street lamp facility of electric power facility, rail facility, expressway, the parts that automobile tire and public fitness equipments etc. need to be fastenedly connected; And simple in structure, easily realize.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of bolt 5 of the present utility model and ratchet 2.
Wherein: 1 is housing; 2 is ratchet; 3 is ratchet; 4 is burglarproof lock; 5 is bolt.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1 and Fig. 2: antitheft retention mechanism of the present utility model comprises and is installed on the ratchet 2 that bolt 5 footpaths make progress, side at ratchet 2 is provided with the ratchet 3 that can block ratchet 2, and a side of ratchet 3 is provided with can push the burglarproof lock 4 that ratchet 3 makes its disengaging ratchet 2 open.The lower end of ratchet 3 is fixed by rotating shaft, and is provided with Returnning spring between ratchet 3 and the rotating shaft.The dead bolt of burglarproof lock 4 is close to described ratchet 3 one side settings, and dead bolt relies on rotation promotion ratchet 3 to overcome Returnning spring disengaging ratchet 2.Ratchet 3 opens and closes by burglarproof lock 4 controls, with the purpose that reaches locking or unclamp ratchet 2.
And above bolt 5, ratchet 2, ratchet 3 and burglarproof lock 4 all are fixedly installed in the housing 1; The unlocking port of burglarproof lock 4 is arranged on the housing 1.
The utility model uses in pairs, and housing 1 is with burglarproof lock 4 and ratchet 3, and ratchet 2 and bolt 5 are combined, and burglarproof lock 4 dead bolts and ratchet 3 cooperate, and burglarproof lock 4 is closed, and ratchet 3 stops ratchet 2 rotations, and the bolt 5 under the ratchet 2 can not rotate.Burglarproof lock 4 is opened, and ratchet 2 can normally rotate.Bolt 5 under the ratchet 2 can normally rotarily open.
