Abstract

The utility model provides a double-stress-glass-tube anti-theft sensor which comprises a glass tube serving as a guardrail, wherein a wire breaking alarm is arranged in the glass tube and connected with a storage battery. The glass tube is of a double-layer structure and is composed of an outer glass tube and an inner glass tube which are sleeved mutually. A spring is arranged at the bottom connection end of the outer glass tube and the inner glass tube and connected with the wire breaking alarm, two ends of the spring are respectively fixedly connected with the outer glass tube and the inner glass tube, and the tops of the outer glass tube and the inner glass tube are fixedly connected. When the glass tube is crushed, stress balance of the spring is broken, and the spring releases stress restraint to return to the free state, drive the wire breaking alarm to move and trigger the wire breaking alarm to give alarms. The double-stress-glass-tube anti-theft sensor is of a mechanically triggering wire breaking alarm structure and is low in manufacture cost, easy to process and manufacture, safe and reliable.

Description

Two stress glass tube theft-proof sensors

Technical field

The utility model relates to a kind of automatic alarm anti-theft device.

Background technology

Stolen for preventing, no matter the occupant of building, one-storey house much need guard place install anti-theft fence at window and other.Common anti-theft fence is processed with metal material, is easy to cutting, and anti-theft effect is poor, and when running into emergency condition such as fire, if indoor resident wants that wire netting has become obstacle on the contrary by the window escape.For avoiding occurring above-mentioned condition; Notification number is that the Chinese utility model patent of CN200985728Y discloses a kind of glass tube electronic anti-theft fence, and this anti-theft fence comprises the fixed beam of railing and non-floating rail, and railing adopts glass tube; Wherein be provided with the electronics wire break alarm in the fixed beam; Establish conducting medium in the glass tube, the conducting medium in each glass tube links to each other with electronics wire break alarm in the fixed beam after connecting the lead series connection.Once destruction, the conducting medium in the glass tube opens circuit as the glass tube of railing, promptly can trigger the electronics wire break alarm and report to the police, and the shortcoming that this glass tube anti-theft fence exists is that the conducting medium cost is high, processing and manufacturing difficulty is big.

Summary of the invention

In order to solve the shortcoming that cost is high, processing and manufacturing difficulty is big that existing glass tube anti-theft fence exists, the utility model provides a kind of pair of stress glass tube theft-proof sensor.

Solve technique scheme, the technical scheme that the utility model adopts is:

A kind of pair of stress glass tube theft-proof sensor comprises the glass tube as railing, and wire break alarm is housed in the glass tube; Wire break alarm connects accumulator; Described glass tube is a double-decker, is made up of the outer glass pipe and the inner glass tube of suit, and the bottom link of outer glass pipe and inner glass tube is provided with spring; Spring is connected with wire break alarm, and the two ends of spring are fixedly connected on outer glass pipe and inner glass tube respectively; The top of outer glass pipe and inner glass tube is fixedly connected.

Under the normal state of alert, spring is in compressive state, and outer glass pipe and inner glass tube bear the rightabout stress that spring applies respectively, and under the state of stress equilibrium, wire break alarm remains static.After the glass tube fragmentation, stress equilibrium is broken, and spring discharges stress constraint and gets back to free state, drives wire break alarm and moves, and triggers wire break alarm and reports to the police.

Described pair of stress glass tube of the utility model theft-proof sensor adopts machinery to trigger the structure of wire break alarm, and cost of manufacture is low, and processing and fabricating is simple and easy, and is safe and reliable.

Description of drawings

Fig. 1 is the structural representation of the two stress glass tube theft-proof sensors of the utility model.

Among the figure, 1-wire break alarm, 2-accumulator, 3-outer glass pipe, 4-inner glass tube; The 5-spring, 6-tubular cross bearer, 7-glass tube plug, 8-glass tube socket, the anti-fall cap of 9-glass tube; The anti-fall cable of 10-, 11-color lamp diode, 12-onsite alarming loudspeaker, 13-radio alarming transmitter, 14-solar panel; The 15-support, 16-support rubber ring, 17-waterproof grommet, 18-glass tube locknut, 19-socket locknut.

Embodiment

Requiring the technical scheme of protection to do below in conjunction with accompanying drawing to the utility model specifies.

The described a kind of pair of stress glass tube theft-proof sensor of the utility model comprises the glass tube as railing, and wire break alarm 1 is housed in the glass tube; Wire break alarm 1 connects accumulator 2; Described glass tube is a double-decker, is made up of the outer glass pipe 3 and the inner glass tube 4 of suit, and the bottom link of outer glass pipe 3 and inner glass tube 4 is provided with spring 5; Spring 5 is connected with wire break alarm 1, and the two ends of spring 5 are fixedly connected on outer glass pipe 3 and inner glass tube 4 respectively; The top of outer glass pipe 3 and inner glass tube 4 is fixedly connected with welding or bonding mode.Break alarm connects known normally closed warning circuit.

At outer glass pipe 4 upper face fixed supports 15, be used for the support glass pipe, fixed support rubber ring 16 on the joint face of support and outer glass pipe.
