Connect the telescopic shaft of each spring, the multiple telescopic shafts of connection be in the cover body one end pushes circle outside；It is described to push
Circle is butted on the housing.
For the present invention by setting fire-retardant shearing device outside cable main, the intensity of a fire when condition of a fire occurring with effective control is climing
Prolong, reduce potential safety hazard as far as possible, reduce loss.During work, when the condition of a fire occurs, during fire spreading to fire-retardant shearing device,
Temperature reaches fuse member by housing, so that fuse member fuses, cutting knife is cut in cable main or straight in the presence of elastic component
Cut-out cable main is connect, effectively to split the cable of its both sides, prevents the intensity of a fire from continuing to spread.Wherein, the blade of cutting knife is away from cable
Main body certain distance so that when fuse member fuses, with enough kinetic energy during the tangential cable main of cutting knife.In addition, when cable or
After its cladding material is cut off, in the presence of device is pushed, the cable of cut-off part both sides or its cladding material pushed open rapidly or
Person is directly separated, with the further effect for improving the cut-off intensity of a fire.
As the present invention preferably, the cutting knife includes the blade of multi-disc gap setting, and the every blade is provided with least one
The individual elastic component and fuse member.The process that the structure to cut or cut off is more efficient, is cut off from multiple angles,
Gap relationships cause blade to be independent of each other in incision.
Fusing hole preferably, in the middle part of the blade is provided with as of the invention, the fuse member passes through the fusing hole, and described
The both ends of fuse member connect the case inside wall.The structure more can guarantee that the timely of cut-out, because fuse member is in fusing
The part in hole can be constantly subjected to a power, Gu when the temperature increases, the part will fuse at first.
As the present invention preferably, the blade of the blade is the arc for coordinating the cable main external surface shape.It is described
Structure causes the stress of the various pieces of blade in cut process to be more uniformly distributed, to ensure the fluency of cut process.
As the present invention preferably, the housing includes pressing close to the heat-insulating and sealing seat of the cable main, located at the sealing
Thermal conductive shell on seat.The heat-insulating and sealing seat is made of not transcalent material, with avoid the intensity of a fire or high temperature by every
Heat seal seat is transmitted in cable main, and thermal conductive shell then ensure that fuse member can fuse in time, to ensure its resistance
Fuel efficiency fruit.
As it is of the invention preferably, the seal receptacle its towards one end of the cable main be provided with seal groove, the sealing
Sealing strip is provided with groove.The structure ensure that the sealing of enclosure interior, to ensure the service life of fire-retardant shearing device.
As the present invention preferably, the clamping ring medial surface, which is provided with, clamps screw thread.The clamping screw thread is further ensured that
The stability of position relationship between clamping section and cable outer layer material, avoids its slip relative to cable, so as to ensure to
Pushed section pushes effect.
It is an advantage of the invention that：It is simple in construction, it is easy to use, cable system can be effectively protected, while fire can be controlled
The sprawling of gesture, to reduce loss.
