69 pairs of self-locking axis 58 reset the promotion of round end 73 and the returning elastic of flexible resetting spring 59, to drive self-locking axis 58
Defining flange 75, fixed hub 53 lock pin driving self-locking chamber 60 in reciprocal telescopic, so as to fulfill to lock pin driving mechanism 8
The clamping and /V of the self-locking limit bayonet 47 of bogie 37 are lifted, changes the position of 8 pin connection slide plate 40 of lock pin driving mechanism
It puts, with limitation position of the locking pin 39 in pattern manhole cover lock unlocking condition and beneficial to locking pin 39 when pattern manhole cover lock is latched
It resets., it is understood that in order to effectively be protected communication pattern manhole cover lock internal mechanism, the internal lock of 1 inside of connection jam plate
The outside of plectrum 6, lock pin driving mechanism 8 and lock tongue rotating mechanism 9 is provided with end cover 7, with promoted use reliability,
Extend the service life of pattern manhole cover lock.
Include magnetization sleeve column 76 with the matching used electronic unlocking device of the pattern manhole cover lock that communicates, the lower end of magnetization sleeve column 76 is provided with
Open keyhole, the upper end of magnetization sleeve column 76 are provided with rotational handle 77, and magnetization unlocking button 78 is provided in rotational handle 77.With profit
With the open keyhole of magnetization sleeve column 76 lower end, electronic unlocking device is socketed in the unlocking bushing 14 of communication pattern manhole cover lock unlocking separator 3
On；Then, by magnetizing the magnetization of 76 dual lock bushing 14 of sleeve column and its inner-cavity structure, the slide cores on bushing inner cavity top are made
15 slide downward of axis, and then promote clutch push rod 16, clutch rotation axis 21 is made to connect with separator end cap 22 and separator pedestal 18
It is connected into one；Rotational handle 77 is recycled to rotate the separator plectrum 10 of clutch rotation axis 21 and its lower end, realize and unlock
Action.
The communication pattern manhole cover lock is in use, the well lid latch hook 12 set on the downside of communication well lid, the lock tongue rotating machine with pattern manhole cover lock
11 phase of the fixing lock tongue clamping of structure 9, and then realize the locking of communication well lid.When need open communication well lid, in communication pipe
Cable when being overhauled and being safeguarded, first, by the magnetization sleeve column 76 of electronic unlocking device through unlocking protective cover 2, be socketed in it is logical
On the unlocking bushing 14 for believing pattern manhole cover lock unlocking separator 3；After electronic unlocking device is verified, authorized to the identity of user, press
Magnetization unlocking button 78 on turn fixed handle 77 magnetizes unlocking bushing 14 using the magnetization sleeve column 76 of electronic unlocking device, allows lining
15 slide downward of slip mandrel on inner cavity top is covered, and then promotes clutch push rod 16, make clutch rotation axis 21 and separator end cap
22 and separator pedestal 18 link into an integrated entity.
Then, then by the rotational handle 77 of electronic unlocking device rotate entire unlocking separator 3 and point of its lower end
From device plectrum 10, and the stirring to external lock plectrum 13 using separator plectrum 10, internal lock plectrum 6 is driven to be swung up；Afterwards, lead to
The driving that internal lock plectrum 6 lifts lock pin driving mechanism 8 bogie 37 is crossed, pin connection slide plate 40 to be driven to rise, and then is made
The pin 39 that locks is extracted out of 9 lock tongue shaft 57 of lock tongue rotating mechanism shaft column pin hole 63, lock tongue shaft 57 can be rotated,
Realize the unlocking of communication pattern manhole cover lock（As shown in figure 23）.Electronic unlocking device can be removed after unlocking, as unlocking bushing 14 magnetizes
Elimination, axis resetting spring 23 pushes up clutch axis 20, clutch push rod 16 and slides mandrel 15 by reseting elasticity,
And then clutch rotation axis 21 is made to be separated with separator end cap 22 and separator pedestal 18.
After communication pattern manhole cover lock is unlocked, well lid is not yet turned on（The lock tongue shaft 57 of lock tongue rotating mechanism 9 does not rotate）When
It waits, the lifting bogie 37 of lock pin driving mechanism 8, the lock pin that lock tongue rotating mechanism 9 is connected to by self-locking limit bayonet 47 drives
In dynamic self-locking chamber 60 on the defining flange 75 of self-locking axis 58, with the drop-off positions of limitation locking pin 39, locking pin is prevented
39 fall after rise in shaft column pin hole 63.When the well lid that communicates is opened, the well lid latch hook 12 of upper lift can drive fix lock tongue 11 and
Lock tongue shaft 57 rotates, and passes through the rotation that lock tongue shaft 57 is located at the self-locking rotor 56 of connection 1 medial end of jam plate, to promote
Self-locking axis 58 on axle sleeve end cap 54 is moved into lock pin driving self-locking chamber 60, so that the lifting driving of lock pin driving mechanism 8
The self-locking limit bayonet 47 of frame 37 is separated from the defining flange 75 of self-locking axis 58, when being latched so as to follow-up pattern manhole cover lock, is locked
The reset of pin 39 is fallen.
After the maintenance and maintenance of the communications cable, communication close well lid；The well lid latch hook 12 of whereabouts can drive fixing to lock
57 negative direction of tongue 11 and lock tongue shaft resets rotation, when the shaft column pin hole 63 of lock tongue shaft 57 rotates back to initial lock position
It puts（Shaft column pin hole 63 and 62 coaxial communication of axle sleeve column pin hole）When, locking pin 39 relies on the dead weight of lifting bogie 37, returns
It falls into the shaft column pin hole 63 of lock tongue shaft 57, realizes the locking of communication pattern manhole cover lock（As shown in figure 22）.Lock tongue shaft 57 is multiple
While position rotates, due to rotating backward for self-locking rotor 56, the thrust that 58 end of self-locking axis is applied eliminates, so that from
Pintle hook lock axis 58 is resetted using the returning elastic of flexible resetting spring 59, realization thereon, and is unlocked for communication pattern manhole cover lock next time
The whereabouts /V of Cheng Zhong, the pin 39 that locks are prepared.
