Abstract
The utility model discloses a locked and unlocked state keeping device for a manhole cover lock, which is simple in structure and convenient to use and can stably keep locked and unlocked states of a manhole cover. The locked and unlocked state keeping device for the manhole cover lock comprises a lock, wherein the lock is connected with a manhole cover locking device; the manhole cover locking device is provided with an electromagnetic locking device; the manhole cover locking device comprises a turnplate; the turnplate is installed on a main shaft; a split baffle ring II is arranged on one side of the turnplate, and the other side of the turnplate is connected with a manhole cover lock connecting rod; the turnplate is provided with a nick; the nick is matched with an electromagnetic locking device; the electromagnetic locking device comprises an electromagnetic valve; the electromagnetic valve is installed on the fixing rack; a piston rod of the electromagnetic valve is connected with an electromagnet poking rod; the electromagnet poking rod is connected with an electromagnet connecting rod and pushes the electromagnet connecting rod to rotate; the electromagnet connecting rod is matched with the turnplate nick of the manhole cover locking device; the electromagnet poking rod is installed on a supporting shaft; and a split baffle ring I is arranged on the supporting shaft. The device utilizes the principle of the electromagnetic valve; under the action of a magnetic field, the piston rod of the electromagnetic valve moves forward or backward, and only when current pulse is absent, the piston rod of the electromagnetic valve are always in the unlocked or locked state, so that the device realizes an unlocked or locked state keeping function for the manhole cover lock.
Description
Technical field
The utility model relates to a kind of well lid locking device, relates in particular to a kind of locking of pattern manhole cover lock, device that the unlatching two condition keeps of being applied to.
Background technology
Urban road is provided with a lot of underground pipeline well lids, and these well lids are stolen or arbitrarily opened for preventing the someone, cause danger to Pedestrians and vehicles, often needs locking.Open or during closed condition, the maintenance of state is very crucial in used being locked in of when locking.Tradition is the mode through spring top bead, but very unstable when strong bump, damages easily.
The utility model content
The purpose of the utility model provides a kind of simple in structure, easy to use exactly for addressing the above problem, the device that the maintenance well lid locking that can be stable or the locking that is applied to pattern manhole cover lock of unlocking condition, unlatching two condition keep.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of locking of pattern manhole cover lock, device that the unlatching two condition keeps of being applied to, it comprises lock, and lock is connected with the well lid locking device, and said well lid locking device is provided with electromagnetic locking device.
Said well lid locking device comprises: rotating disk, and it is installed on the main shaft, and rotating disk one side is provided with split washer II, and opposite side is connected with the pattern manhole cover lock connecting rod; Rotating disk is provided with otch, and otch cooperates with electromagnetic locking device.
Said electromagnetic locking device comprises: electromagnetic valve; It is installed on the fixed mount, and the piston of electromagnetic valve bar is connected with the electromagnet driving lever, and the electromagnet driving lever is connected with the electromagnet connecting rod; And promoting the rotation of electromagnetism connecting rod, the electromagnet connecting rod then cooperates with the rotating disk otch of well lid locking device.
Said electromagnet driving lever is installed on the back shaft, on back shaft, is provided with split washer I.
The utility model utilization electromagnetic valve principle, piston of electromagnetic valve bar move ahead or retreat under the effect in magnetic field; Utilize this function, electromagnetic valve drives the electromagnet driving lever, and the electromagnet driving lever blocks rotating disk or breaks away from rotating disk; Owing to do not re-use the mode of existing spring top bead, when pattern manhole cover lock is in opening be, because the electromagnet driving lever can not block rotating disk; Therefore it will be in unlocking condition all the time, in case be in when needing locking, then the electromagnetism driving lever can firmly pin rotating disk; It is maintained the lock status; As long as current impulse does not have, the piston of electromagnetic valve bar has so just been realized the maintenance effect of the state of unblanking or locking of pattern manhole cover lock with the consistent state of unblanking or locking that is in.
The beneficial effect of the utility model is: simple in structure, unblank or locking state can be stable maintenance.
