Abstract

The utility model discloses a safety anti-theft lock for a telephone, which comprises a lock body, a fixed telephone, a magnet part, an enameled wire, a metal frame and swinging pins, wherein the enameled wire and the metal frame are arranged at the outer peripheral surface of the magnet part, one end of the enameled wire is electrically connected with a fixed telephone line, the other end thereof is connected with an external street line, the lock body is provided with an electromagnetic suction device capable of controlling the lock to be locked and unlocked, the swinging pins are arranged at two ends of a circuit close to the electromagnetic suction device and penetrate through the magnet part; by being matched with the fixed telephone, the magnet part, the enameled wire and the metal frame, the electromagnetic suction device is arranged on the safety anti-theft lock body so as to control the swinging pin to swing slightly and connect the circuit of the electromagnetic suction device, thus controlling the lock body to be locked or unlocked and further realizing good anti-theft effect; furthermore, the safety anti-theft lock has simple and reasonable structure, low cost and simple, easy and convenient operation; in addition, when the safety anti-theft lock needs to be unlocked, a preset fixed telephone number is needed to be dialed, and the lock body is not left with a key hole, so that the anti-picking function is achieved and the safety performance is improved; and if the fixed telephone is transacted with the call display function, the fixed telephone number and the illegal use time of a theft can be recorded.

Description

The phone safety anti-theft lock

Technical field

The utility model relates to the theftproof lock technical field, especially a kind of phone safety anti-theft lock that can obviously improve anti-theft effect.

Background technology

On the market, traditional theftproof lock is locked and the release principle by it, can be divided into mechanical antitheft lock and electronic type theftproof lock; Yet, no matter be mechanical antitheft lock electronic type theftproof lock, all have the following disadvantages: (1) is though mechanical lock has certain advantage on antitheft, but, its complex structure, operation are numerous tired, and the manufacturing cost height, are unfavorable for applying of product; And electronic safety lock, its cost is higher, and the circuit complexity, is disturbed easily on antitheft, and anti-theft effect is also uneven; (2) on traditional theftproof lock, generally can leave keyhole so that unblank, yet, on the door body, leave keyhole, pried open by the people easily, its antitheft effect, obviously relatively poor.Therefore, people thirst for always, can design aly to have simple and reasonable for structurely, and cost is low, and anti-theft effect is good, and operate simple and easy, safety anti-theft lock easily.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of simple and reasonable for structure, and cost is low, and anti-theft effect is good, and operates simple and easy, convenience, can not leave the safety anti-theft lock of keyhole.

The purpose of this utility model is achieved in that

A kind of phone safety anti-theft lock, comprise lock body, it also includes landline telephone, magnet iron piece, enamel-covered wire, metal frame and balancing point, enamel-covered wire and metal frame are arranged on the magnet iron piece outer surface, enamel-covered wire one end is electrically connected with fixation phone line, the external street of other end line, and described lock body is provided with can control the electromagnetic attracting device of locking and unblanking, balancing point is arranged on the circuit two ends near electromagnetic attracting device, and balancing point passes magnet iron piece; This kind of theftproof lock by electromagnetic attracting device is installed, and cooperates landline telephone, magnet iron piece, enamel-covered wire and metal frame on lock body, control balancing point and slightly swing, and being communicated with the electromagnetic attracting device circuit, thereby the control lock body is locked or unblanked; And it is simple and reasonable for structure, and cost is low, operates simple and easy, convenient; Have again,, lock body is opened or closed, therefore, can not leave keyhole on the lock body, thereby reach the effect of pick-proof, improve safety because this kind of theftproof lock need be put through default fixed telephone number; If landline telephone has incoming call display function, can also write down robber's telephone number and crime time thereof.

The purpose of this utility model can also adopt following technical measures to solve:

As more particular embodiment, described enamel-covered wire is wrapped in the magnet iron piece surface, and metal frame is fixed on the magnet iron piece periphery.

Described balancing point is with the switch of swing mode as the control electromagnetic attracting device, to connect or to disconnect the circuit of electromagnetic attracting device.

The beneficial effects of the utility model are:

(1) the utility model phone safety anti-theft lock by electromagnetic attracting device is installed, and cooperates landline telephone, magnet iron piece, enamel-covered wire and metal frame on lock body, controlling balancing point slightly swings, to be communicated with the electromagnetic attracting device circuit, the control lock body is locked or is unblanked, and realizes good antitheft effect; And it is simple and reasonable for structure, and cost is low, operates simple and easy, convenient; If landline telephone has incoming call display function, can write down robber's telephone number and crime time thereof;

(2) this kind of phone safety anti-theft lock when unblanking, need be put through default fixed telephone number, just can open lock body, therefore, can not leave keyhole on the lock body (door body), reaches the effect of pick-proof, improves safety.

Description of drawings

Fig. 1 is the schematic diagram of the utility model phone safety anti-theft lock.

The specific embodiment

As shown in Figure 1, a kind of phone safety anti-theft lock, comprise lock body 1, it also includes landline telephone 2, magnet iron piece 3, enamel-covered wire 4, metal frame 5 and balancing point 6, and enamel-covered wire 4 and metal frame 5 are arranged on magnet iron piece 3 outer surfaces, and enamel-covered wire 4 one ends are electrically connected with fixation phone line, the external street of other end line 7, described lock body 1 is provided with can control the electromagnetic attracting device 11 of locking and unblanking, and balancing point 6 is arranged on the circuit two ends near electromagnetic attracting device 11, and balancing point 6 passes magnet iron piece 3.

Described enamel-covered wire 4 is wrapped in magnet iron piece 3 surfaces, and metal frame 5 is fixed on magnet iron piece 3 peripheries of band enamel-covered wire; Described balancing point 6 is with the switch of swing mode as control electromagnetic attracting device 11.

Operating principle: when unblanking, only need put through default fixed telephone number, after landline telephone 2 receives signal, the meeting output signal also makes enamel-covered wire 4 connect street lines 7, magnet iron piece 3 is connected circuit can produce induction, make balancing point 6 swings, the electromagnetic attracting device 11 on the lock body 1 is switched on or switched off, and realizes the effect of locking or unblanking; If landline telephone 2 has incoming call display function, can also write down robber's telephone number and crime time thereof.
