Abstract
The utility model relates to electronic fence system accessories, in particular to a tension on-off device, which comprises a female sleeve, a male shaft, a casing and a spring. The female sleeve, the male shaft and the spring are all arranged in the casing, a pull wire hole is arranged on the casing, a male shaft guide piece is arranged on the male shaft, a female sleeve guide piece is arranged on the female sleeve which is hollow, the male shaft is arranged in the female sleeve, the male shaft guide piece is in movable contact fit with the female sleeve guide piece, a retaining ring matched with the spring is arranged on the female sleeve, one end of the spring abuts against the inner wall of the casing, and the other end of the spring abuts against the retaining ring. When the structure is used, a fence alloy wire is connected with the female sleeve, the female sleeve moves under the effect of tension (a normal state after a device is installed), the female sleeve guide piece is contacted with the male shaft guide piece, and an alarm works normally in a connection state. If a fence line is cut off, the tension on-off device is reset, the male shaft guide piece breaks off with the female sleeve guide piece to enable a main machine connection wire to break off with the fence alloy wire, so that a loop cannot be formed (a line of a main machine is broken off and the main machine alarms).
Description
Technical field
The utility model relates to a kind of electronic enclosure system accessory, especially a kind of pulling force break-make device.
Background technology
At present, in circumference security protection electronic enclosure system, system is mainly by alarm host machine, terminal pole, load bar, intermediate bar, terminal pole geometrical clamp, terminal pole insulator, load bar insulator, intermediate bar insulator be connected lead and form.In present technology; Alarm host machine and alloy wire all are to be connected by the terminal pole insulator through insulated wire; Therefore the terminal pole insulator can play insulation and bear tension, but can not play the on-off function after pulling force lost efficacy, and as long as the related personnel with the short circuit of alarm host machine output terminal after; Cut off alloy wire again, alarm host machine will not produce the break alarm signal so.
Therefore, present electronic enclosure system can't realize that alarm host machine wire of output terminal (enclosure wall top alloy wire) is cut off after the short circuit again, and alarm host machine can produce the function of reporting to the police, and therefore still there is very big potential safety hazard in present electronic enclosure system.
Summary of the invention
The purpose of the utility model is, the short circuit of a kind of alarm host machine output terminal is provided after, cut off line again, alarm host machine still can produce the pulling force break-make device of break alarm signal.
The utility model solves the technical scheme that its technical matters adopted: a kind of pulling force break-make device, it is characterized in that comprising female cover, public axle, housing, spring, and female cover, public axle, spring all are arranged in the housing; Housing is provided with the backguy hole, and public axle is provided with public spindle guide sheet, and mother puts and is provided with female cover guide card; Female cover hollow; Public axle is arranged in female cover, and public spindle guide sheet moves contact matching with female cover guide card, puts mother and is provided with the baffle ring adaptive with spring; Spring one end withstands inner walls, and the other end withstands baffle ring.
Further being set to of the utility model: housing comprises upper shell, lower house, and upper shell and lower house fasten, and public axle is fixedly installed on the lower house; Mother puts the mother who is provided with a U type and overlaps guide card, and female cover guide card one end is than broad, and the other end is narrow; Female being set on the public axle, public spindle guide sheet is arranged on the head of public axle, and public spindle guide sheet is protruding; Public spindle guide sheet overlaps mother between the U matrix of guide card, and the width of public spindle guide sheet overlaps between the width of guide card two ends between mother.
Further being set to of the utility model: also comprise clasp, fixed support, be provided with screw thread at an end of housing, clasp and housing spin; Be provided with in the clasp side and buckle; Fixed support is the U type, and support bracket fastened U type opening is provided with and buckles adaptive hook, buckles.
Said structure when in use, the enclosure wall alloy wire is connected with female cover, under the effect of pulling force; Female cover moves, and female cover guide card contacts with public spindle guide sheet, under the connected state; The warning horn operate as normal, if the enclosure wall circuit is cut off, then pulling force break-make device resets; Public spindle guide sheet and female cover guide card break off, thereby make main frame connect lead and the disconnection of enclosure wall alloy wire, therefore can't form loop (main frame break alarm).
