Abstract
The utility model relates to a controllable observation window for a door ring and a door lamp, which is composed of an observation window, an emitter of the door ring and the door lamp, a receiver of the door ring, a receiver of the door lamp, and a 220V electric bulb, wherein, the observation window is composed of a housing and a push-pull box; the emitter of the door ring and the door lamp is arranged in the push-pull box; the receiver of the door lamp is connected with a control switch arranged on the 220V electric bulb at the corridor mouth. When a button of the emitter is pushed for once or continuous many times (set by people), the emitter emits a group of or many groups of hybrid encoding signals with address bit and data bit information; after the receiver of the door ring receives the signals, the circuit of the door ring are triggered to send out different door ring sound through filtering, amplifying, reshaping, checking and encoding, and counting to prompt the host that the guest is a stranger or an acquaintance; when unlocking the lock needs lighting at night, the button can be continuously pushed for many times, and the electric bulb arranged at the corridor mouth is automatically lighted by the receiver of the door lamp and turned out after a delay.
Description
The utility model relates to a kind of device of security door peep hole, especially has the observation port of control gate light doorbell function.
At present, the security door observation port is to design slideway in the door-plate interlayer, and the push-and-pull box places slideway, and the control hand button on the door body is connected with the push-and-pull box by connecting rod, rotate the hand button, the push-and-pull box moves in slideway, and observation port is opened, in a single day this observation port damages, and the user can't repair, and function singleness.
The purpose of this utility model is, but the unlatching of controlling gate light night that has of integral demounting maintenance is provided, and can connect the difference pronunciation of doorbell with the number of times decision of pressing button, with the observation port of distinguishing uncooked and cooked people's function.
Because the drawback of above-mentioned traditional product existence, the constantly research of the design people's process, design, and after studying sample and improvement repeatedly, create the utility model finally.
The technical solution of the utility model is as follows:
The utility model is by observation port, gate light doorbell emitter, the gate light receiver, doorbell receiver and 220V bulb constitute, observation port is made up of shell and push-and-pull box, gate light doorbell emitter is arranged in the push-and-pull box, the gate light receiver is connected with the gauge tap of the 220V bulb that is installed in the corridor mouth, be provided with battery compartment in the push-and-pull box, end face closes with the battery cap seal, the push-and-pull box outside is sealed by peephole is fixing with metal cover board, having unthreaded hole on the metal cover board cooperates with light sensation device on the emitter, detect the bright intensity of corridor mouth, push-and-pull box cunning is fitted into shell, the unlatching button is set on the push-and-pull box, spacer with open the button primary and secondary and cooperate and be fixed together, spacer matches with locating slot on the shell, locking push-and-pull box slides in shell, realizes the unlatching of observation port.The inside and outside side plate openings of security door is bumped into the whole observation window in the door from security door interior plate opening part during use, is screwed on door, and the button on the emitter is fixed on outdoors on the side plate.Gate light doorbell emitter (Fig. 1) is interconnected and is formed by on-off circuit (A portion), light sensation circuit (B portion), coding circuit (C portion), radiating circuit (D portion); Doorbell receiver (Fig. 2) is interconnected and is formed by wireless receiving circuit (E portion), decoding circuit (F portion), pulse-scaling circuit (G portion), doorbell circuit (H portion); Gate light receiver (Fig. 3) is interconnected and is formed by wireless receiving circuit (I portion), decoding circuit (J portion), pulse-scaling circuit (K portion), gate light circuit (L portion).When the stranger is visiting, generally only press button No. one time, signal is through the coding circuit coding of emitter, to there be the hybrid coding of address bit and data bit information to send into radiating circuit and send triggering signal one time, the wireless receiving circuit of doorbell receiver, the signal filtering that receives, shaping, after the amplification, export when the signal that receives through the decoding circuit verification is consistent with self coding, again through the counting of pulse counting circuit, after the integration time-delay, trigger doorbell circuit, make loudspeaker send doorbell sound, press button (the artificial setting) for several times continuously, emitter promptly can send triggering signal for several times continuously, and the pulse-scaling circuit meter of doorbell receiver is for several times disconnected, triggers doorbell circuit and sends and be different from the doorbell sound of stranger when visiting; Night, press button (the artificial setting) for several times continuously, deliver to pulse-scaling circuit together, pulse-scaling circuit work with the data bit information that receives when the signal of the decoding circuit verification emitter emission of gate light receiver is consistent with the coding of self, the output high level, the gate light circuit has possessed the condition that is triggered, and gate light is lighted, at this moment, the doorbell receiver is because the light sensation device effect that is provided with in the doorbell circuit, when light is arranged, the doorbell pronunciation, it is mute not have bright doorbell.Daytime, press button continuously, the data bit output of decoding block is a low level in the gate light receiver, gate light is not lighted.
The utility model compared with prior art has tangible advantage and good effect, promptly overcome the installation question of security door doorbell, have again and press a button or press (the artificial setting) for several times continuously, doorbell sends different sound, and prompting owner guest is stranger or acquaintance; At night, press continuously and for several times can open electric light.Solve the corridor dark of going home night, given the worry of unblanking to bring.
