CN202142147U - Hanging chain - Google Patents

Abstract

The utility model aims to provide a hanging chain having a prominent anti-theft function. The hanging chain mainly includes a chain composed of an alarming circuit unit and a lead, and a common hook. The circuit module is composed of a buzzer and a normal close relay. The buzzer and the normal close relay are connected in series. In a normal condition, a coil of the relay is electrified. The normal close relay is opened. A power source used in the circuit is 3.6 V. The chain is a part of the circuit unit. The chain is made from a lead connecting with the coil of the relay. When the chain is cut, the coil of the relay is not electrified. The relay returns to be close. The buzzer loop is electrified and the buzzer calls to alarm.

Description

A kind of chaining

Technical field

The utility model relates to a kind of electric anti-thief device, is specially a kind of chaining.

Background technology

Wallet, mobile phone chaining are not only attractive in appearance, and have certain antitheft effect, therefore are widely used in daily life.But the antitheft effect of common chaining is very limited, often has the lawless person to take advantage of confusion in the life and cuts off the situation generation that chaining is implemented theft afterwards, has brought bigger loss for people's productive life.

Summary of the invention

The utility model provides a kind of anti-theft feature more outstanding chaining in order to solve the problems referred to above of existing chaining.

The utility model comprises warning circuit module and chaining and the common hook made with lead; Circuit module is composed in series by a hummer and normally closed relay, relay coil energising under the normal condition, and normally closed relay breaks off, and hummer does not pipe, and the used power supply of circuit is 3.6V; Chaining belongs to the part of circuit module, make by a lead that links to each other with relay coil, after cutting off chaining, relay coil outage, this moment the relay recovery closure state, the energising of hummer loop, buzzer call is reported to the police.

The beneficial effect of the utility model is: design has more hommization, efficiently solves the weak drawback of existing chaining anti-theft feature, and is convenient and practical, simple in structure, designs ingenious.

Description of drawings

Fig. 1 is the working circuit diagram of the utility model circuit module

Fig. 2 is the utility model structural representation

Among the figure: the 1-circuit module; The 2-chaining; The 3-hook;

Embodiment

Shown in accompanying drawing, the utility model comprises circuit module 1, chaining 2, and hook 3, chaining 2 is exactly the ab section among Fig. 1, and when chaining was cut off, equivalent electrical circuit broke off between the ab, and hook 3 and the hook above the chaining are respectively applied for and connect health and valuables.

During practical implementation, circuit module 1 can be processed exquisite small and exquisite ornaments pattern with chaining 2, and the volume of circuit module must be done little as far as possible; Chaining can be made the pattern of arbitrary shape, under the normal condition, and the relay coil energising in the circuit module; Relay switch breaks off; After chaining was cut off, relay switch was closed, and the hummer energising pipes.

Claims (1)

1. a chaining is characterized in that comprising warning circuit module and chaining and the common hook made with lead; Circuit module is composed in series by a hummer and normally closed relay, relay coil energising under the normal condition, and normally closed relay breaks off, and hummer does not pipe, and the used power supply of circuit is 3.6V; Chaining belongs to the part of circuit module, make by a lead that links to each other with relay coil, after cutting off chaining, relay coil outage, this moment the relay recovery closure state, the energising of hummer loop, buzzer call is reported to the police.
