Abstract

A security door includes a door, a door frame, a detection control device and a warning device, whose special point is that the detection control device consists of a contact switch, a micro computer time-control switch and a relay. The contact switch is arranged on the door or the door frame, and the contact switch and the relay get connection in series, and then they connect with the micro computer time-control switch. The contact switch of the relay is connected with the warning device. Compared with the prior art, the utility model has advantages of timely warning sound generation and high sensitivity.

Description

A kind of security door

Technical field:

The utility model relates to a kind of door with theftproof performance.

Background technology:

The existing security door that has alarm sound generally is made of detection control apparatus, warning device, and detection control apparatus generally is arranged on the contact switch control device on door lock tongue or the lock core.During use, when detection control apparatus is touched improperly, warning device will be activated, and sends alarm sound, to threaten robber and warning.This kind security door owing to be arranged on the installation and the status requirement strictness thereof of the contact switch on door lock tongue or the lock core, is not easy to meet the requirements, and therefore, or is easy to generate false alarm, or insufficient sensitivity, can not in time send alarm sound.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of alarm sound that can in time send, highly sensitive security door.

The utility model is to realize like this, comprise door, doorframe, detection control apparatus, warning device, its special feature is that detection control apparatus is made of contact switch, micro computer time switch, relay, contact switch is arranged on door or the doorframe, contact switch links to each other with the micro computer time switch with relay series connection back, and the contact switch of relay links to each other with warning device.Present most of family is owing to be busy with one's work, the number of times of going home in one day seldom, and, generally all stay indoor after going home, particularly than the people of late home, all the more so, like this, the time period of opening-closing door is constant with regard to basic fixed, mainly concentrate on section and section the work hours in the morning the quitting time in the evening, like this, people keep opening or closing in the time period of needs by regulating the micro computer time switch, and the switch of micro computer time switch was disconnected in the time period of needs, other time period then remains closed, so that people can not cause alarm activation after contact switch is touched yet when the time period inward of going home, and in section At All Other Times, as long as door is opened, contact switch is touched, and warning device will start, and sends warning message.Owing to do not need the structure of contact switch and specific (special) requirements be installed, therefore, guarantee sensitivity of the present utility model and reliability.

Here, relay is a time relay, controls the time that warning device is reported to the police and continued by the time relay.

The utility model compared with the prior art, owing to adopted the product micro computer time switch that has used the maturation that can arbitrarily buy on the market organically combining in conjunction with other parts and with them, therefore, have and in time to send alarm sound, highly sensitive advantage.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a circuit diagram of the present utility model.

The specific embodiment:

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

As shown in the figure, the utility model comprises door 1, doorframe 2, detection control apparatus 3, warning device 4, its special feature is that detection control apparatus 3 is made of constant close contact switch S A, micro computer time switch 6, time relay T, constant close contact switch S A is arranged on door 1 or the doorframe 2, constant close contact switch S A links to each other with micro computer time switch 6 with time relay T series connection back, and the constant close contact switch T1 of time relay T links to each other with warning device 4.When door was closed, constant close contact switch S A disconnected, when door is opened, and constant close contact switch S A closure.

Here, constant close contact switch T1 is connected the back of constant close contact switch S A.During work, in the time period that micro computer time switch 6 remains closed, door is opened, after the constant close contact switch S A closure, time relay T action, the normally closed switch T1 closure on the time relay T, warning device 4 continuous firings, warning, close until door, constant close contact switch S A disconnect or time relay T time is up automatic disconnection till.

Claims (3)

1, a kind of security door, comprise door, doorframe, detection control apparatus, warning device, it is characterized in that detection control apparatus is made of contact switch, micro computer time switch, relay, contact switch is arranged on door or the doorframe, contact switch links to each other with the micro computer time switch with relay series connection back, and the contact switch of relay links to each other with warning device.

2, security door according to claim 1 is characterized in that relay is a time relay.

3, security door according to claim 1 and 2 is characterized in that contact switch T1 is connected the back of contact switch SA.
