Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable bridge with a rodent-proof function. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, which are composed of brackets, brackets and installation accessories. The cable trays in buildings can be erected independently or attached to various buildings (structures) and pipe gallery brackets. They should have the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts must be galvanized. For cable trays installed in the open air outside buildings, if they are near the sea or in a corrosion zone, the material must have the physical properties of anti-corrosion, moisture resistance, good adhesion and high impact resistance.

[0003] The utility model with application number 202020579733.6 discloses a rat-proof cable bridge, by arranging a card block and a limit rod, since the cross-sections of the card block and the limit rod are both regular hexagons, and a limit groove matched with the limit rod is opened on the right side of the horizontal rod, and a bayonet matched with the card block is also opened on the device body. When the card block is inserted into the device body, the card block is restricted, and the limit rod is inserted into the limit groove opened by the horizontal rod, so that the horizontal rod is restricted and cannot rotate. When the card block is pulled out of the device body, the limit rod no longer restricts the rotation of the horizontal rod, and the forward rotation of the knob drives the horizontal rod to rotate forward, and the rotating gear also rotates accordingly, so that the meshing gear rotates relatively, and the rotation of the meshing gear drives the threaded rod to rotate. Since a thread matching with the threaded rod is provided in the meshing sleeve rod, the fixed rod and the slider restrict the rotation of the meshing sleeve rod, thereby When the engagement sleeve rod is rotated by the threaded rod, the engagement rod moves upward, and the sliding cover plate slides upward through the connecting rod, so that the cover plate is pulled open, and the cable can be passed through the inner cavity of the equipment body and sent to the wire trough, and then the knob is rotated in the opposite direction. Similarly, the sliding cover plate slides down to clamp the cable, and then the clamping block is clamped into the equipment body, so that the horizontal rod is restricted and cannot rotate, and the sliding cover plate is fixed, so that the wire inlet of the wire trough is blocked, so that mice cannot enter the interior of the wire trough to damage the cable, thereby achieving the effect of anti-rat, so that the cable is effectively protected, thereby increasing the service life of the cable, strong practicality, and convenient operation, by setting the mounting plate, the mounting plate is sleeved on the outside of the wire trough, and then the mounting plate is fixed with bolts, the equipment body can be fixedly installed on the wire trough, achieving the effect of easy installation, thereby saving manpower and cost;

[0004] However, when the sliding cover plate of the above-mentioned rat-proof cable bridge is lowered to block the line inlet of the wire duct, a certain gap is still left to allow the cable to protrude, so that mice may drill into the wire duct through the gap, affecting the rat-proofing effect. The mounting plate and the sliding cover plate in the above-mentioned rat-proof cable bridge are mainly installed at the end of the wire duct to prevent mice from entering the wire duct from the end. The cable heats up during long-term use. Since the cable bridge adopts a closed structure for rat-proofing, the heat dissipation efficiency is low. Therefore, the utility model proposes a cable bridge with rat-proofing function to solve the problems existing in the prior art. Utility Model Content
