Abstract

The utility model relates to a theft-proof well cover with a cipher lock, which comprises a cover and a pedestal, wherein, the inner side of the cover is provided with a lock drum, and the bottom of the lock drum and the cover are provided with a lock sheet shaft which is provided with a lock sheet provided with gaps. One end of the lock sheet shaft is positioned at the outer side of the cover and is provided with a cipher wheel, the pedestal is provided with lock tines of which the positions exactly aim at a bar-shaped hole on the lock drum, and the bar-shaped hole is matched with the lock sheet in the lock drum to control the opening and the closure of the well cover. The lock drum can also be provided with secret lock tines. The theft-proof well cover with a cipher lock can be opened without a key, and people only need to know the secret code combination. The theft-proof well cover with a cipher lock solves the defect that the existing theft-proof well cover can not be opened caused by the blockage of the key hole, and has complicated structure and inconvenient opening.

Description

Theft-proof well cover with cipher

The utility model relates to the upper and lower water channel well lid in hydraulic engineering, underground water well lid and road or the garden, is a kind of anti-stealing manhole cover that is provided with coded lock specifically.

In the prior art, well lid is to be made of base and lid, generally do not have to unclamp or the lock of fixed cover, thereby the lid of well lid is usually taken away or takes away by the people easily, and cause the ruined problem of facility in safety or the well.For this reason; CN88205122 once disclosed a kind of Safety well cover that is provided with lock; though this well lid can prevent lid and be opened or take away by the people; but its weak point is just can open with key; and keyhole regular meeting can not open well lid because of the ground dirt pierces or fill in foreign material, and the general more complicated of the structure of this well lid.

The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art part, and a kind of cipher anti theft well lid of opening without key is provided.

Technical solution of the present utility model is, a kind of cipher anti theft well lid has lid and base, and its special character is that it comprises:

(1) locks tube, be loaded on the inboard of lid, leave a bar hole longitudinally on it;

(2) locking plate axle is loaded on lock tube bottom and the lid 2, and an end that is positioned at the lid outside is equipped with cipher wheel;

(3) locking plate is positioned at above-mentioned lock tube, is installed on the locking plate axle, and can establishes thereon gap position by holding screw adjustment;

(4) the lock tooth is loaded on the above-mentioned base, and the bar hole on the lock tube is just in time aimed in its position, and by with the match switching of incompatible control well lid of locking plate.

Locking plate axle in the above-mentioned technical solution can comprise a center lock bobbin and be enclosed within one, two or three hollow locking plate axles in its outside successively, a locking plate respectively is housed on each locking plate axle and be provided with a cipher wheel.

Accompanying drawing has been described a preferred embodiment of the present utility model.

Fig. 1 is the sectional structure chart of this embodiment;

Fig. 2 is the structural representation that this embodiment locks tube;

Fig. 3 is the structural representation of this embodiment locking plate;

Fig. 4 is the A-A sectional view of Fig. 3;

Fig. 5 is the structural representation of this embodiment privacy lock tooth;

Fig. 6 is the B-B sectional view of Fig. 5.

Each label declaration is as follows among the figure:

1-nut, 2-are locked tube, the 3-locking plate, and the 4-lid, the 5-cipher wheel, the 6-holding screw, the 7-base, 8-locks tooth, the hollow locking plate axle of 9-, 10-center lock bobbin, 11-bar hole, 12-breach, 13-privacy lock tooth, 14-boss, 15-toothholder.

Below in conjunction with accompanying drawing present embodiment is elaborated:

Know referring to Fig. 1, this cipher anti theft well lid has a base 7 and lid 4, lid 4 is connected through the hinge on base, the inboard of lid 4 connects a lock tube 2, one end of center lock bobbin 10 is loaded on the lock tube bottom, limit the position with a nut 1, to prevent that its generation from moving axially, the other end passes lid 4, the outside of center lock bobbin is with two hollow shafts 9 successively, on each axle a locking plate 3 is housed respectively in the lock tube, and locking plate 3 is fixed on the axle by holding screw 6, the tail end of each respectively is provided with a cipher wheel 5, is aligned in sequence with " 0 " above character code on each cipher wheel.

Referring to Fig. 2, have a bar hole 11 on this lock tube, the passage when inserting or taking out the lock tube as lock tooth 8.

Referring to Fig. 3, Fig. 4, locking plate 3 is one and matches with a lock tube inwall, and design has by outer rim extends the circular piece of breach 12 to the center, and its outer rim is provided with boss, and the effect of breach 12 is to cooperate closing or opening with control lock with the lock tooth.

Referring to Fig. 5, Fig. 6, the well lid of often opening for needs, password combination is given away secrets when preventing that well lid from opening, can establish privacy lock tooth 13, the increment of privacy lock tooth 13 is provided with boss 14, its role is to after lid is opened, locked tooth and withdraws from, can match with the boss that is located on the locking plate, snap in and be locked on the tube, to prevent cryptocompromise, toothholder 15 can be connected on the lock tube 2 by a hinge.

During use, lock tooth 8 is installed in the position that to aim at bar hole 11 on the lock tube 2 on the base 7, rotate three cipher wheel 5 respectively, make three breach 12 on the locking plate all aim at bar hole 11, to lock tooth 8 snaps in the lock tube 2, careless again rotational password wheel 5 is to upset the number number, and the lid 6 of well lid just is locked on the base 7 like this.When opening selected password combination number is forwarded on the straight line, and aim at the switching mark, can open well lid.When well lid is opened, give away secrets in order not make selected password combination, can at once privacy lock tooth 13 be locked on the bar hole of tube 2.When readjusting password combination as need, holding screw 6 is unclamped, again selected password combination number is forwarded on the straight line, aim at and open and close mark, keeping under the motionless situation of cipher wheel then, in the lock tube, stir locking plate 3 one by one, make the breach 12 consistent bar holes of aiming on the lock tube on all locking plates, tighten holding screw 6 more again and get final product.

In conjunction with the foregoing description as can be seen, advantage of the present utility model is to open and close with password combination, need not use key, thereby the phenomenon of well lid can not occur can not opening because foreign material stop up keyhole, and it is relatively simple for structure, unlatching is convenient.
