Abstract

The utility model relates to a mobile phone chain, and concretely relates to an anti-theft mobile phone chain. The utility model resolves problem that the prior mobile phone chain has no anti-theft function. The anti-theft mobile phone chain comprises a chain body, wherein one end of the chain body is fixed with a suspension ring for connecting with a mobile phone, the other end is fixed with a circuit box for packaging a wire break type alarm circuit therein, an alarm wire of the wire break type alarm circuit is fixed in the chain body, and a fastener is fixed on the circuit box. The chain of the utility model has reasonable and smart physical design, and can effectively preventing the mobile phone from being stolen while has beautiful appearance.

Description

The antitheft mobile phone chain
Technical field
The utility model relates to mobile phone chain, is specially a kind of antitheft mobile phone chain.
Background technology
Existing mobile phone chain mostly is common ironwork, alloy product or plastic products, and its function only limits to decorate; Except decoration function, existing mobile phone chain is powerless aspect antitheft mobile phone, in case promptly mobile phone chain is cut off, mobile phone just can be stolen at an easy rate.
Summary of the invention
The utility model provides a kind of antitheft mobile phone chain in order to solve the problem that existing mobile phone chain does not possess anti-theft feature.
The utility model is to adopt following technical scheme to realize: the antitheft mobile phone chain, comprise serobila, and serobila one end is fixed with and is used for the link that is connected with mobile phone; Encapsulate the circuit box of break line type warning circuit in the serobila other end is fixed with, be provided with the alarm line of break line type warning circuit in the serobila, circuit box is provided with buckle.
Base chip when described break line type warning circuit comprises battery BT1, its 8 pin and 1 pin respectively with NE555 that battery BT1 both positive and negative polarity is connected, through the capacitor C 2 loud speaker LS1 that basic chip 3 pins are connected during with NE555, battery BT1 two ends are parallel with: the series arm of resistance R 1, resistance R 2, capacitor C 1, and resistance R 3 and the series arm that is arranged at the alarm line in the serobila; 7 pins of base chip are connected with the connected node of resistance R 1, resistance R 2 during NE555, and 2 pins, 6 pins are connected with the connected node of resistance R 2, capacitor C 1, and 4 pins are connected with the connected node of resistance R 3, alarm line.
During use, circuit box is fixed on user's the belt or suitcase by the buckle on the circuit box, serobila just often, alarm line is intact, 4 pin input low levels of NE555 time base chip in the break line type warning circuit, 3 pin output low levels of NE555 time base chip then, loud speaker LS1 is sounding not; As artificial stealing mobile phone, when serobila was blocked, alarm line was blocked, 4 pin input high levels of base chip during NE555, and then 3 pins of NE555 time base chip output high level drives loud speaker LS1 sounding, reminds the user to note, thereby prevents that mobile phone is stolen.
The utility model reasonable in design, ingenious can not only prevent effectively that mobile phone is stolen, and not lose elegant in appearance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic diagram of the utility model break line type warning circuit.
Among the figure: 1-circuit box, 2-buckle, 3-serobila, 4-link.
Embodiment
The antitheft mobile phone chain comprises serobila 3, and serobila 3 one ends are fixed with and are used for the link 4 that is connected with mobile phone; Encapsulate the circuit box 1 of break line type warning circuit in serobila 3 other ends are fixed with, be provided with the alarm line X1 of break line type warning circuit in the serobila 3, circuit box 1 is provided with buckle 2.
Base chip when described break line type warning circuit comprises battery BT1, its 8 pin and 1 pin respectively with NE555 that battery BT1 both positive and negative polarity is connected, through the capacitor C 2 loud speaker LS1 that basic chip 3 pins are connected during with NE555, battery BT1 two ends are parallel with: the series arm of resistance R 1, resistance R 2, capacitor C 1, and resistance R 3 and the series arm that is arranged at the alarm line X1 in the serobila 3; 7 pins of base chip are connected with the connected node of resistance R 1, resistance R 2 during NE555, and 2 pins, 6 pins are connected with the connected node of resistance R 2, capacitor C 1, and 4 pins are connected with the connected node of resistance R 3, alarm line X1.
