Abstract

The utility model belongs to a cipher anti-theft manhole cover, comprising a the manhole cover and a base. A cipher locking device is arranged between the manhole cover and the base, and the locking device is mainly composed of a cipher wheel, a driving device, a bumping wheel and a locking pin. The bumping wheel of the bottom of the manhole cover is correspondingly matched with the cipher wheel arranged at the surface of the manhole cover. The edge of the bumping wheel is provided with a gap, and is fastened with a groove of the locking pin. A bolt of the locking pin is inserted in the groove of the base, and a lock hole is arranged on the locking pin. The anti-theft manhole cover has the advantages of simple and reasonable structure, easy fabrication, convenient operation, high safety, good anti-theft effect. The cipher locking and the bolt locking are all provided.

Description

The cipher anti theft well lid
The utility model belongs to a kind of anti-stealing manhole cover that is provided with password.
Well lid is necessity setting of underground installation, well lid lose the concern that causes increasing people, especially city inhabitant is concerned about more, losing of well lid not only influenced the city appearance of the city, more seriously is to have brought inconvenience to the pedestrian, jeopardizes pedestrains safety.A lot of people endeavour to study the anti-theft measure of well lid, designed the anti-stealing manhole cover of various ways, situation is improved, and is 92201654 " cipher anti theft well lid " as application number, is exactly wherein a kind of preferably, but, its anti-theft effect is still not ideal, and the lock tube of band password by which floor intussusception is formed, precision prescribed is higher, gives to manufacture to make troubles.
The purpose of this utility model is to provide a kind of more reasonable structure, makes more convenient, the better cipher anti theft well lid of anti-theft effect.
The purpose of this utility model can be realized by following scheme:
Cipher anti theft well lid described in the utility model, comprise well lid (2), base (1), the password locking device is arranged between well lid and base, this locking device is mainly by cipher wheel (7), transmission device, gear wheel (3) and lock pin (5) are formed, the gear wheel of well lid bottom surface (3) matches corresponding by transmission device with the cipher wheel (7) on well lid surface, there is a breach at the edge of gear wheel (3), the groove of gear wheel (3) edge and lock pin (5) fastens, and the dead bolt of lock pin (5) is inserted in the groove of base has lockhole (4) on the lock pin (5).
In the above-mentioned locking device, can be with snap (6) on the lock pin (5), so that make the dead bolt locking that automatically resets.
Described anti-stealing manhole cover, its transmission device are gear drive, reliable transmission, stable performance.
For finish laterally, transmission longitudinally, use laterally, vertically conical gear (9,10) cipher wheel (7) are connected with contrate gear (9) by axis of rotation (8), vertical gear (10) and contrate gear (9) mesh, gear wheel (3) and coaxial the fixedlying connected of vertical gear (10).
Described anti-stealing manhole cover, gear wheel has two on the same lock pin.Certainly, also a plurality of gear wheels can be set as required, the gear wheel number is many more, and the deciphering of password is just difficult more.
Described anti-stealing manhole cover, lock pin locking device have two groups, strengthen locking effect.Equally also can be arranged to organize more, but can bring a lot of inconvenience to making.Though two groups, still organize more, the best symmetric arrangement of lock pin locking device, the locking great efforts, and help making and using.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, structural representation of the present utility model also are an embodiment.
The A-A partial sectional view of Fig. 2, Fig. 1.
Among the figure: 1 base, 2 well lids, 3 gear wheels, 4 lockholes, 5 lock pins, 6 snaps, 7 cipher wheel, 8 axis of rotation, 9 contrate gears, 10 vertical gears.
As shown in the figure, be one or four cipher anti theft well lids, four gear wheels of four cipher wheel control are totally two groups of lock pin locking devices.
The cipher wheel 7 on well lid 2 surfaces and the horizontal conical gear 9 of well lid bottom surface, connect by axis of rotation 8, vertically conical gear 10 is meshed with horizontal conical gear 9, gear wheel 3 and vertical conical gear 10 coaxial fixedlying connected are fixed on the reinforcing rib of well lid 2 bottom surfaces together, and there is a breach at gear wheel 3 edges, the groove of gear wheel 3 edges and lock pin 5 fastens, the dead bolt of lock pin 5 is inserted in the groove of base 1, and snap 6 is enclosed within on the lock pin 5, and lockhole 4 is arranged on the lock pin 5.
Password and the breach on gear wheel 3 edges selected on the cipher wheel 7 are to adjust in advance to work good.When rotational password wheel 7 during to selected password, the breach on gear wheel 3 edges is just in time corresponding with the groove of lock pin 5, and password locking is in opening-wide state.Wrench is inserted lockhole 4 rotations, the dead bolt of lock pin 5 just withdraws from from base 1 groove again, and can open well lid 2 this moment.When closing, the dead bolt of lock pin 5 leans on the elastic force of snap 6 on the lock pin 5 to rebound automatically and inserts in the groove of base 1, and rotation cipher wheel 7 is in the lock state 5 of gear wheel 3 and lock pins and gets final product.
Can find out in sum, the utlity model has following advantage:
1, simple and reasonable, make easily, easy to use.
2, gear drive is stable, reliable.
3, the locking between password wheels control gear wheel and lock pin, four password combination lockings are separated Close rate is low, and is safe and reliable. Be furnished with the dead bolt locking of lock pin, form multiple defence line, further Strengthen anti-theft effect.
4, most of parts are ironcasting, and cost of material and cost of manufacture are all very low.
