Abstract

The utility model relates to the field of cable tunnel safety facilities, and more specifically relates to a novel anti-theft well cover. The novel anti-theft well cover comprises a well cover body. The well cover body is equipped with a groove. An electronic cipher lock handle and input buttons are fixed to the groove. A protective cover hinged to the well cover body is arranged on the groove. The protective cover is flush with an upper surface of the well cover body. An electronic cipher lock pin is disposed on the lower portion of the well cover body. Insulating material wraps a power supply box on the lower portion of the well cover body. A well head and the electronic lock pin are equipped with electrode slices in corresponding positions. The two electrode slices that do not contact each other form a switch. The power supply box is connected with an audible-visual alarm through the switch. The novel anti-theft well cover has a simple structure and is convenient to operate. If the well cover needs to be opened, an operator inputs a cipher of an electronic cipher lock through the input buttons, and the well cover can be successively opened only if the cipher is correct and the electronic cipher lock pin retracts. Once an act of theft occurs, the electrode slices on the electronic cipher lock pin and the well head contact each other, a circuit is conducted, and the audible-visual alarm alarms to guard against thieves.

Description

Novel antitheft well cover

Technical field

The utility model relates to security implementation field, cable tunnel, is specifically related to a kind of novel antitheft well cover.

Background technology

Have in the market the anti-stealing manhole cover of all styles of, but all Datong District being different, is all to address the stolen phenomenon of well lid from material and the mechanical anti-theft design aspect of well lid, not intelligence.

Utility model content

For solving the problems of the technologies described above, the purpose of this utility model is: a kind of novel antitheft well cover is provided, while opening, needs staff to input electronic cipher, if open manhole cover by force will be reported to the police by audible-visual annunciator.

The utility model for the technical scheme that its technical problem of solution adopts is:

Described novel antitheft well cover, comprise well lid body, also comprise electronic password lock, electronic password lock is provided with handle, lock core and input key, on well lid body, groove is set, the fixing electronic cipher lock handle of groove and input key, groove is provided with the over cap hinged with well lid body, over cap is concordant with well lid body upper surface, electronic cipher lock pin is located at well lid body below, well lid body below is by wrapped with insulation power pack, the position that well head and electronic lock core are relative is provided with electrode slice, two non-touching electrode slices form a switch, power pack is connected with audible-visual annunciator by switch.

Preferably; described slot opening place is made as stairstepping, is greater than other end opening near an end opening of well lid body upper surface, and over cap covers at slot opening place; ladder-type structure can stop that over cap unrestrictedly falls, and has weight through out-of-date extrusion damage electronic password lock with preventing well cover top.

Preferably, described audible-visual annunciator is arranged in groove, compact conformation, and alarm sound is loud.

When the utility model need to be opened, operating personnel input electronic cipher lock cipher by input key, while only having password correct, electronic cipher lock pin just can shrink, and smooth opening well lid, if when inoperative personnel want to open by force well lid enforcement theft, the electrode slice that electronic cipher lock pin and well head place arrange is in contact with one another, circuit turn-on, audible-visual annunciator is reported to the police, warning pilferage personnel.

Compared with prior art, the utlity model has following beneficial effect:

The utility model is simple in structure, easy to operate, need to open time, operating personnel input electronic cipher lock cipher by input key, while only having password correct, electronic cipher lock pin just can shrink, smooth opening well lid, if when inoperative personnel want to open by force well lid enforcement theft, the electrode slice that electronic cipher lock pin and well head place arrange is in contact with one another, circuit turn-on, audible-visual annunciator is reported to the police, warning pilferage personnel, slot opening place is made as stairstepping, an end opening near well lid body upper surface is greater than other end opening, over cap covers at slot opening place, ladder-type structure can stop that over cap unrestrictedly falls, there is weight through out-of-date extrusion damage electronic password lock with preventing well cover top, audible-visual annunciator is arranged in groove, compact conformation, and alarm sound is loud.

In figure: 1, well lid body; 2, handle; 3, lock core; 4, input key; 5, groove; 6, over cap; 7, audible-visual annunciator.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model embodiment is described further:

As shown in Figure 1-2, novel antitheft well cover described in the utility model, comprise well lid body 1, also comprise electronic password lock, electronic password lock is provided with handle 2, lock core 3 and input key 4, groove 5 is set on well lid body 1, the fixing electronic cipher lock handle 2 of groove 5 and input key 4, groove 5 is provided with the over cap 6 hinged with well lid body, over cap 6 is concordant with well lid body 1 upper surface, electronic cipher lock pin 3 is located at well lid body 1 below, well lid body 1 below is by wrapped with insulation power pack, well head and the relative position of electronic lock core 3 are provided with electrode slice, two non-touching electrode slices form a switch, power pack is connected with audible-visual annunciator 7 by switch.

Wherein, described groove 5 opening parts are made as stairstepping, are greater than other end opening near an end opening of well lid body 1 upper surface, and over cap 6 covers at groove 5 opening parts, ladder-type structure can stop that over cap 6 unrestrictedly falls, and has weight through out-of-date extrusion damage electronic password lock with preventing well cover top; Described audible-visual annunciator 7 is arranged in groove 5, compact conformation, and alarm sound is loud.

When the utility model need to be opened, operating personnel input electronic cipher lock cipher by input key, while only having password correct, electronic cipher lock pin 3 just can shrink, and smooth opening well lid, if when inoperative personnel want to open by force well lid enforcement theft, electronic cipher lock pin 3 is in contact with one another with the electrode slice that well head place arranges, circuit turn-on, audible-visual annunciator 7 is reported to the police, warning pilferage personnel.
