Description
Technical field
The present invention relates to a kind of weaving technology field of lockset.
Background technology
At present, the antitheft locking between some street lamp appliance doors and the lamp stand directly uses the screw riveting on lamp stand appliance door; Also have some antitheft lockings directly to be made up of lock core and locking plate, opening and closing all are rotary locking cylinders, and lock core drives locking plate and rotates, by locking plate and lamp stand wall cooperate realize; Also have the common padlock of the antitheft direct employing of lamp stand to block, above-mentioned simple lock, the anti-theft effect that can not play, some are baroque, the lock of good anti-theft effect but is not suitable for the antitheft of street lamp post, and use cost is also higher.
Summary of the invention
The invention provides a kind of street lamp post appliance door theftproof lock, purpose is to solve existing theftproof lock anti-theft effect defect of bad.
The present invention includes the doorframe that cooperates with lamp stand, door-plate, one side of described door-plate is hinged and connected on the described doorframe, on described doorframe, the bottom fixedly installs latch plate respectively, center in the outside of described door-plate connects lock core, described lock core can rotate freely, middle part in the inboard of described door-plate arranges driving lever, described driving lever is fixedly connected on the inner of described lock core, be hinged a locking bar of vertically arranging respectively at the two ends of described driving lever, locking bar positioning sleeve on the left part of described door-plate inside upper part is fixedly connected, at the fixedly connected locking bar positioning sleeve down of the right part of described door-plate lower inside, described two locking bars be plugged on respectively described on, following locking bar positioning sleeve, right part in described door-plate inside upper part arranges first leg, left part in described door-plate lower inside arranges second leg, between described first leg and driving lever, first spring is set, one end of described first spring is connected on described first leg, the other end of described first spring is fixedly connected on the left part of described driving lever, between described second leg and driving lever, second spring is set, one end of described second spring is connected on described second leg, the other end of described second spring is fixedly connected on the right part of described driving lever, and the free end of described two locking bars cooperates the inboard that is arranged in described latch plate respectively.
When the present invention uses, doorframe is fixedly attached to the preformed hole place that lamp stand is equipped with electrical equipment, when door-plate cuts out locking, the free end of locking bar is inserted in the inboard of latch plate, hold driving lever by first, second spring, make driving lever be in the heeling condition of locking direction, guarantee the locking of theftproof lock; When door-plate need be opened, by the key lock core that turns clockwise, lock core drove driving lever and rotates, and driving lever is extracted two locking bars from latch plate, outwards door-plate is drawn back then to get final product, and this anti-theft lock structure is simple, can play good anti-theft effect.
The present invention arranges position-limitting pin at described door-plate, and described position-limitting pin correspondence is arranged in the below of described driving lever, and described position-limitting pin can prevent that the driving lever rotation is excessive, causes locking bar to break away from the locking bar positioning sleeve.
