Abstract

The utility model relates to a metal anti-theft window used for prevent people from illegally entering a room. A push-button switch is arranged at one end of the anti-theft window, and the movable contact piece of the push-button switch is fixed to the other end of the anti-theft window by a drag rope. Tow sets of static contacts respectively lead out a wire joining AB and CD, all the button type switch wire junctions such as AB and CD are merged at the first and second contact point after paralleling. The first contact point is electrically connected with the negative pole of power supply, an alarm after paralleled with the high voltage generator, one terminal is connected with the second contact point and the other terminal is connected with the positive pole of power supply. The high voltage creating terminal of the high voltage generator is connected with the anti-theft window, and the lower terminals of the first and second contact point are equipped with an electromagnet, and the upper terminal is equipped with permanent magnet. An iron swing plate is equipped between the electromagnet and the permanent magnet, the swing plate can swing around one terminal of it, and the magnet coil and the power supply are electrically connected. When the magnet coil is cut off power, the permanent magnet can adsorb the swing plate, and the swing plate connects the first contact point and the second contact point at that time. It is not only with simple structure and low cost but also consumes small quantity of electric energy or consumes no power when serves the function of anti-theft.

Description

Burglary-resisting window

(1), technical field

The utility model relates to a kind of burglar of preventing and illegally enters within doors metal anti-theft window.

(2), background technology

At present, anti-theft product is varied, and principle also is not quite similar, and far infrared burglary-resisting window, vibration burglary-resisting window, broken string burglary-resisting window etc. are arranged.Because these products all must be switched on antitheft a work time spent all the time, cause consumed power, waste energy.Also have these products because the cost height is difficult to penetration and promotion.

(3), summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of burglary-resisting window, and it is not only simple in structure, and cost is low, and is playing the antitheft time spent consumed power not of doing.If use the anti-line function of cutting off, power consumption is low, but the protection better effects if.

The technical scheme in the invention for solving the technical problem is: at the push-button switch of a plurality of band back-moving springs of internal fixation of burglary-resisting window one end, each push-button switch has two groups of static contacts, between two groups of static contacts movable contact spring is arranged, movable contact spring is fixed by the stay cord and the burglary-resisting window other end, the length of stay cord gets final product for making movable contact spring be in two groups of static contacts centres, promptly two groups of static contacts all are off-states, two groups of static contacts are drawn wire joining AB respectively, CD, the wire joining of all push-button switch such as AB, be attempted by a contact after the parallel connections such as CD, on two contacts, one contact is electrically connected with power cathode, a termination two contacts after alarm and the high pressure generator parallel connection, another termination positive source, the high pressure generation termination burglary-resisting window of high pressure generator, one contact, there is electromagnet the lower end of two contacts, there is permanent magnet the upper end, swing sheet made of iron is arranged between electromagnet and the permanent magnet, the swing sheet can be swung around the one end, electromagnet coil is electrically connected with described power supply, electromagnet both positive and negative polarity wire-wound is on window, and with lead with picking out, when electromagnet coil cuts off the power supply, permanent magnet will be swung sheet and suct, and swing sheet with a contact and two contactings this moment.

Because adopt permanent magnet and electromagnet, so it is not only simple in structure, cost is low, and antitheftly does the time spent and only consume small amount of electrical energy rising; use the anti-line function of cutting off, power consumption is low, but the protection better effects if; if do not use and anti-cut off the line function, just consumed power no longer is more economical.

(4), description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model structural representation;

Fig. 2 is the E place enlarged drawing among the utility model Fig. 1;

Fig. 3 is the utility model circuit theory diagrams.

(5), the specific embodiment

As shown in Figure 1, 2, push-button switch at a plurality of band back-moving springs 9 of internal fixation of burglary-resisting window 3 upper ends of metal tube, each push-button switch has between 7,8, two groups of

static contacts

7,8 of two groups of static contacts movable contact spring 5 is arranged, and movable contact spring 5 is fixed by stay cord 2 and burglary-resisting window 3 lower ends.The length of stay cord 2 is in two groups of static contacts, 7,8 middle getting final product for making movable contact spring 5, and promptly two groups of

static contacts

7,8 all are off-states.As shown in Figure 3, two groups of

static contacts

7,8 are drawn wire joining AB, CD respectively, are attempted by after the wire joining of all push-button switch such as the parallel connections such as AB, CD on a contact 12, two contacts 13, and a contact 12 is electrically connected with power cathode.Alarm 15 and one termination, two contacts 13, high pressure generator 16 back in parallel, another termination positive source, the high pressure generation termination burglary-resisting window 3 of high pressure generator 16.Shocked by electricity serial connection hand switch K4 in high pressure generator 16 circuits when keeping in repair burglary-resisting window 3.There is electromagnet 14 lower end of one contact 12, two contacts 13, and there is permanent magnet 10 upper end, and swing sheet 11 made of iron is arranged between electromagnet 14 and the permanent magnet 10, and swing sheet 11 can be around its right-hand member swing, and the coil of electromagnet 14 is electrically connected with described power supply.When the coil blackout of electromagnet 14, permanent magnet 10 will be swung sheet 11 and suct, and swing sheet 11 this moment a contact 12 and two contacts 13 are connected.

In order to improve the anti-line effect of cutting off, the structure between described permanent magnet 10, a contact 12, two contacts 13, swing sheet 11 and the electromagnet 14 is totally two covers.Going here and there respectively in the coil circuit of described two cover electromagnet 14 has hand switch K1, K5, and two contacts, 13 other strings have hand switch K2, K3.In the time of need not preventing cutting off the line effect, open K1, K2, K3, K5.

During use, closed hand switch K1, K2, K3, K4, K5, electromagnet 14 gets electric, will swing sheet 11 and inhale down, and a contact 12, two contacts 13 disconnect, and the utility model is in anti-theft state.In case the robber destroys stay cord 2 by sawed-off or be pulled with burglary-resisting window, wire joining AB or CD will be connected, alarm 15 and high pressure generator 16 electricly work simultaneously, report to the police and add high pressure to burglary-resisting window, play antitheft effect.If electromagnet 14 line conductors are cut off, electromagnet 14 loses magnetism, and permanent magnet 10 sucts movable contact spring 11, and a contact 12 and two contacts 13 are connected, and alarm 15 and high pressure generator 16 must electricly be worked simultaneously, play antitheft effect equally.
