Abstract
The utility model relates to a circuit protection element, and in particular relates to a circuit power-off fireproof device which comprises an outer sleeve, wherein lead inserting tubes are fixed at two ends of an inner cavity of the outer sleeve; lead tubes are fixedly connected with the inner ends of the two lead inserting tubes; lead moving rods are connected with the inner ends of the two lead tubes; a conductive thimble is arranged between the two lead moving rods; one end of the conductive thimble is fixedly connected with one of the lead moving rods; the other end of the conductive thimble props against one end part of the other lead moving rod; a spring in a compressed state is arranged between the two lead tubes. The device is simple in structure, low in cost and high in practicability, when a fire happens to a circuit, the circuit can be cut off, then the fire is prevented from spreading along the circuit, precious time for extinguishing the fire is obtained, the economic loss caused by a fire hazard is reduced, and casualties caused by the fire hazard are avoided.
Description
Technical field
The utility model relates to a kind of circuit protecting element, specifically, relates to a kind of down circuitry firebreak device.
Background technology
In actual life, many fire have that conducting wire is on fire to cause, due to power-off protection apparatus not being set on most of circuits; after circuit is on fire, the intensity of a fire can be along conducting wire rapid spread, thereby causes larger economic loss; serious, also can cause personnel's injures and deaths.
Summary of the invention
The purpose of this utility model is, a kind of down circuitry firebreak device is provided, to solve above-mentioned technical problem.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of down circuitry firebreak device, it is characterized in that: comprise outer tube, the two ends of described outer tube inner chamber are fixed with respectively wire Inserting Tube, the inner of two wire Inserting Tubes is fixedly connected with respectively conduit, the inner of two conduits is connected with respectively wire movable rod, between two wire movable rods, be provided with conduction thimble, one end of described conduction thimble is fixedly connected with one of them wire movable rod, and the other end contacts the end at another wire movable rod; Between described two conduits, be provided with the spring in compressive state.
beneficial effect:compared with prior art, the utility model is simple in structure, cost is low, practical, run into circuit situation on fire, when propagation of flame is during to down circuitry firebreak device, after outer tube is burnt, spring is just by abrupt release, under the elastic force effect of spring, conduction thimble hightails the end of wire movable rod, thereby circuit is cut off, and then stops the intensity of a fire to spread along circuit burning, for fire-fighting fire extinguishing wins the quality time, reduce the economic loss that fire brings, avoid or reduce the casualties that fire causes.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
the specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, down circuitry firebreak device described in the utility model, comprise outer tube 2, the two ends of described outer tube 2 inner chambers are fixed with respectively left side wire Inserting Tube 10 and right side wire Inserting Tube 5, their the inner is fixedly connected with respectively Guide spool 9 and right side conduit 5, the inner of two conduits is connected with respectively left side wire movable rod 8 and right side wire movable rod 6, between two wire movable rods, be provided with conduction thimble 7, one end of described conduction thimble 7 is fixedly connected with and is electrically connected to right side wire movable rod 6, the other end contacts in the end of left side wire movable rod 8 and is electrically connected to, between described two conduits, be provided with the spring 3 in compressive state.
While installing and using, wire 1 inserts respectively wire Inserting Tube, conduit successively from two ends, and is all electrically connected to wire movable rod.Under normal condition, the wire at two ends, by two wire movable rods and the conducting of conduction thimble, guarantees circuit turn-on.Run in circuit situation on fire, when propagation of flame is during to down circuitry firebreak device, after outer tube 2 is burnt, spring 3 is just by abrupt release, under the elastic force effect of spring 3, conduction thimble 7 hightails the end of left side wire movable rod 8, thereby circuit is cut off, and then stops the intensity of a fire to spread along circuit burning, for fire-fighting fire extinguishing wins the quality time, reduce the economic loss that fire brings, avoid or reduce the casualties that fire causes.
