Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to figs. 1 to the cipher lock for well cover shown in Fig. 8, include described in main body 1, lock core shaft 2, sliding piece 3 and latch hook 4
Main body 1 is to be fixedly mounted on the fixed block of the inner side of well lid 5, and the lock core shaft 2 is rotatablely installed on the body 1, and the lock core shaft 2 is located at
The opening position of through hole 51 that well lid 5 is provided with, the sliding piece 3 are the moving block installed in lock core shaft 2；Described latch hook 4 is pendulum
The clamping latch fitting of dynamic installation on the body 1, the latch hook 4 rotate sliding piece 3 by lock core shaft 2 and arrive set angle, are dialling latch hook 4
With the edge clamping of well head 6 or release under well lid 5 in the presence of moving plate 3, lock and unlock function is realized.
In embodiment, described lock core shaft 2 is provided with interior hexagonal keyhole, to make lock core shaft 2 more stably be fixedly mounted on master
On body 1, while performance is improved, a password scale disk 12 is additionally provided with described main body 1, the password scale disk 12 is arranged on
The upside of well lid 5, for showing the rotational angle of lock core shaft 2, described cylinder 1 and password scale disk 12 are divided by more bolts 7
The both sides up and down of well lid 5 are not fixed on.The cylindrical support body 11 of fixing lock mandrel 2 is provided with the body 1.Described sliding piece 3
It is made up of upper cryptographic block 31 and lower cryptographic block 32, described upper cryptographic block 31 is rotatably installed on cylindrical support body 11, lower password
Block 32 is fixedly mounted in the lock core shaft 2 of cylindrical support body 11.Specifically, described upper cryptographic block 31 and lower cryptographic block 32 are two
Block annular moving block, the upper downside of cryptographic block 31 are provided with upper trundle 311, and the lower upside of cryptographic block 32 is provided with underdrive pin 321, described
Upper cryptographic block 31 rotates driving by lower cryptographic block 32, and stirring upper trundle 311 by the underdrive pin 321 of lower cryptographic block 32 rotates
Cryptographic block 31 is driven to rotate.
Described upper cryptographic block 31 and lower cryptographic block 32 are respectively equipped with unlocking recess 33 of the same size, the unlocking recess 33
Width it is corresponding with latch hook 4, formed latch hook 4 unlock when solution fore shaft.Described latch hook 4 is made up of lock 41 and lock house 42, institute
The lock 41 stated is one piece of swinging block for carrying well head bayonet socket 411,
Described lock house 42 is one piece of swinging block for carrying a pintle hook lock mouth 421, and described lock 41 and 42 upper ends of lock house lead to
Cross a fixture 43 and swing installation on the body 1, the fixture 43 can be a fixture with installation groove, described lock 41
Rotating shaft is utilized respectively in groove with lock house 42, the lower end of lock 41 and lock house 42 is connected by a connection piece 44,
Lock 41 and lock house 42 is set synchronously to swing.
To improve the performance of latch hook 4, latch hook 4 is preferably swung realization and lock and unlocking function, it is described to latch 41
The position side of well head bayonet socket 411 it is relative overweight opposite side, described well head bayonet socket 411 be an oblique angle mouth, and pintle hook lock mouth 421 is one
Oblique angle mouth.Therefore when latching 41 and lock house 42 is unlocked, with deadweight automatic swing, lock house 42 is made to be swung at unlocking recess 33,
And when well head bayonet socket 411 and pintle hook lock mouth 421 set bevel mouth, lock and unlock is more smooth, and performance is more preferable, specifically
, when well lid, which unlocks, to be pulled out, the oblique angle mouth by lock 41 makes lock 41 leave well lid well head 6, just as slide-and-guide is swung
The smooth unblock of well lid can be pulled out, avoided stuck；When well lid is being locked, led by the oblique angle mouth of lock house 42 as slip is swung
To, make sliding piece 3 lock house 31 swing out under successfully down slip into lock house 42 in, then by deadweight swing return lock automatically
Tightly.
During operation, using the Allen key of routine, the interior hexagonal keyhole on rotational password lock pin axle 2, by it is suitable, inverse (or
Reversely) clockwise rotates lock core shaft 2, the numeral for making the mark in lock core shaft 2 be respectively aligned on the password scale disk 12 of setting
Afterwards, coded lock is in released state, and manhole cover can normal switch.
Because lock core shaft 2 is connected with lower cryptographic block 32, lock core shaft is not connected to upper cryptographic block 31.
When coded lock unlocks：It is suitable the inner hexagonal hole in Allen key reeve lock core shaft 2 when manhole cover 5 is in and closed
Clockwise rotates lock core shaft 2, the numeral on the password scale disk 12 of the mark alignment settings in lock core shaft 2, passes through rotation
Lock core shaft 2 drives lower cryptographic block 32, and the underdrive pin 321 on lower cryptographic block 32 stirs cryptographic block 31, and lower cryptographic block 32 drives
The upper trundle 321 of upper cryptographic block 31, lock house 42 so as to which the unlocking recess 33 of upper cryptographic block 31 is alignd first.Another mistake hour hands side
Enclosed to lock core shaft 2 to 1/4 is rotated, another numeral of the mark alignment preset password dial 12 in lock core shaft 2, by turning
Movable lock core axle 2 drives lower cryptographic block 32, the alignment lock of unlocking recess 33 house 42 under the password scale disk 12 of setting, when close up and down
The unlocking recess 33 of code block align simultaneously lock house 42 when, coded lock be in released state, and in opening manhole cover, coded lock carries upwards
When rising, the latch hook 4 of coded lock is swung to the right in the force action of external force, and the lock 41 of latch hook 4 promotes lock house by connector 44
42, after cryptographic block up and down before rotates, the unlocking recess 33 of upper and lower cryptographic block has alignd simultaneously locks house 42, and lock house 42 can
Move right, at this moment latch hook 4 leaves the neck (leaving the edge of well head 6 under above-mentioned well lid 5) in walling crib, and lockout failure is husky
Well lid is raised opening.
When coded lock is locked：After manhole cover closes (closing), because of Action of Gravity Field, latch hook 4 is being connected by lock 41
Part 44 drives and leaves the pintle hook lock mouth of the unlocking recess 33 of upper and lower cryptographic block, i.e. lock house 42 perpendicular to the earth's core, lock house 42 under lock house 42
421 are located at 3 times clampings of sliding piece, at this moment using conventional Allen key, the lock core shaft 2 that rotational password is locked, upper and lower cryptographic block
Unlocking recess 33 stagger lock house 42, lock house 42 can not be swung to the right again, and lock house 42 withstands lock 41 by connector 44, that is, locks
Hook 4 can not be swung to the right, and when external force is lifted up opening manhole cover, latch hook 4 can not be swung to the right, and latch hook 4 is hooked in walling crib
Neck (hooking the edge of well head 6 under above-mentioned well lid 5), manhole cover 5 can not be opened, and manhole cover is in the lock state.
