Abstract
The utility model relates to a protecting means of locks. A protecting cap which can be opened is arranged in front of a lock body and used for covering a locking hole. The protecting cover is connected with a brake which is controlled by a drive unit. Moreover, a control unit can generate a specific signal which is used for controlling the operation of the drive unit. The utility model has the advantage that because the locking hole is in a hidden state, a stranger can not unlock or damage the lock body by using the locking hole. In addition, the utility model also provides a double protection function for the existing door lock and the safety is raised.
Description
The utility model is a kind of protective device of lock, refers to the protective device of mechanical door lock especially.
Lock is article commonly used in a kind of life, through being usually used in the protection of opposite house.The existing machinery door lock all is provided with a lockhole that exposes, and when general generation was stolen, the burglar at first will open door lock from lockhole by master key, or pierces to destroy door lock from lockhole with instrument.In addition, some people fills in lockhole for children's curiosity or mischief psychology with foreign matters such as metal, seccotines, to such an extent as to this lock can't be opened.
The purpose of this utility model is to provide a kind of protective device of lock, to address the above problem.
The technical scheme that the utility model adopted as shown in Figure 1, it is made up of over cap (1), driver element (3), brake (2), control module (4) and corresponding power supply, it and the various mechanical door lock that has lockhole are used, and wherein over cap (1) is contained in the place ahead of lockhole; Driver element (3) is made up of receiver (31) and driver (32); Brake (2) is connected between over cap (1) and the driver (32); Control module (4) is the signal generator that mates mutually with above-mentioned receiver (31); when it sends certain signal; receiver (31) receives this signal and makes above-mentioned driver (32) work; control over cap by brake (2) and open or close, thereby lockhole is exposed or hidden.
Above-mentioned control module (4) and receiver (31) can produce and receive control signal with forms such as digital coding formula, magnetic induction types, and by present electronic technology level, the design of its physical circuit is not difficult, and existing many prior aries can be used for reference.
Advantage of the present utility model is that it can make lockhole be in hidden state, so the stranger can not utilize lockhole to open or destroy lock body, and in addition, the utility model also makes existing door lock obtain the double protection function, has improved safety greatly.
Below in conjunction with embodiment the utility model is further described.
Fig. 1: principle schematic of the present utility model.
Fig. 2: the structural principle intention of a kind of embodiment of the utility model.
The A-A sectional view of Fig. 3: Fig. 2.
Fig. 4: the structural principle intention of the another kind of embodiment of the utility model.
The sectional view of Fig. 5: Fig. 4.
Embodiment 1: shown in Fig. 2,3, over cap (1) covers lockhole (51) by the place ahead that a guide rail is arranged on lock body (5), and it can horizontally slip to expose lockhole (51) along guide rail.Brake in this example (2) is a tooth bar, and it and over cap (1) are consolidated.Driver (32) is a motor, and it is connected with tooth bar as brake (2) by machine driven system.Control module in this example (4) is one to be arranged on key (42) last casket body, and this key is used to open lock body (5), is provided with a radiating circuit that produces control signal in the casket body, and this radiating circuit is controlled by the button of being located at the casket external surface (41).Receiver in this example (31) be one with above-mentioned control module (4) in the radiating circuit signal receiving circuit of mating mutually; when it receives the control signal that above-mentioned radiating circuit sends, can produce corresponding signal and be used for the revolution of control as driver (32); so slide by rack drives over cap (1), thereby open or close over cap (1).
Embodiment 2: present embodiment and embodiment 1 described structure are basic identical, just the part of over cap are made spline-simulating, and this part of over cap is connected with driver by machine driven system, can obtain the effect identical with embodiment 1.
Embodiment 3: shown in Fig. 4,5, in the present embodiment, a side (11) of over cap (1) links in side the place ahead of lock body (5), and locates to be provided with a prominent arm (12) at this side (11).Control module (4) be fixed on over cap (1) near, it utilizes an electronic keyboard to produce control signal.Receiver (32) is correspondingly an electronic circuit.Driver (32) comprises that one is equipped with the motion bar (321) of electromagnet on it.Brake (2) is a connecting rod, and its end is connected with above-mentioned motion bar (321), and the other end is connected on the prominent arm (12) on the over cap (1).After receiving the correct signal that transmits from control module (4) when above-mentioned receiver; drive magnet drives motion bar (321) and moves, and motion bar is being opened in the mode of swing by connecting rod and prominent arm (12) drive over cap (1) as brake (2).
