Clamping mechanism for cable through-going device

Abstract

This invention relates to a clamping unit of cable through devices, which sets upper and lower block notches on the up and down slants of a left wedged block and sets upper and lower block notches on the slants of a right wedged block, sets right and left block strips on the right and left slants of an upper wedged block and block strips on the lower wedged block, and both the notches and the strips are jointed correspondingly and matched in slide, a long screw rod passes through a through hole of the sleeve of the right wedged block and screw-joints with the long screw hole of the sleeve of the left block.

Description

Technical field: [0001] The present invention relates to a device for routing cables or wires through wall panels. In particular, an accessory for the device. Background technique: [0002] In movable structures such as various buildings and ships, a large number of cables or wires are passed through walls or partitions of these structures. At the opening of the wall or partition, in order to seal and protect the cable from fire, smoke, gas and water, etc., a cable penetration device is usually used, which is Swedish patent specification 217276, which discloses a cable Through the device, the device is provided with a rigid frame, on one side of the frame there are a number of elastic fillers for firmly clamping the cables, in which a corresponding number of separate cables are installed, and on the other side of the frame There is a wedge assembly and a tensioning device. When the tensioning device is tightened, the wedge can be pushed, and the wedge exerts pressure on th...

Problems solved by technology

At the opening of the wall or partition, in order to seal and protect the cable from fire, smoke, gas and water, etc., a cable penetration device is usually used, which is Swedish patent specification 217276, which discloses a cable Through the device, the device is provided with a rigid frame, on one side of the frame there are a number of elastic fillers for firmly clamping the cables, in which a corresponding number of separate cables are installed, and on the other side of the frame There is a wedge assembly and a tensioning device. When the tensioning device is tightened, the wedge can be pushed, and the wedge exerts pressure on the filler to form the sealing and protection function of the cable penetration device. The above structure and other similar devices, Its composition includes different scattered parts, and there are many operation steps in purchasing, storing, assembling and dismantling, which is complicated and inconvenient. In view of these shortcomings, the Chinese patent name "cable passing device" patent number 95195526.8, A new structure is disclosed, characterized in that the device comprises an outer frame, at least one module-based cable gland and a terminal seal, characterized in that four wedges are held together by a flexible band , the function is to hold a plurality of wedges movably with each other, so that a plurality of wedges and the screw device jointly form a contained component that can be easily loaded into the frame, this technology Although the solution solves the technical problem of simplifying the operation steps, its disadvantage is that the 4 sections of flexible belts added to keep the four wedges together not only greatly complicate the manufacturing process, but also increase the production cost , multi-segment belts and multiple wedges are vulcanized into a single piece, and any manufacturing defect of any belt or wedge may cause the overall scrap of the combined single piece, which will increase the production cost of the device, and the structure of the screw device is complicated. After tightening, the screw end is exposed for a long period, which is very unsafe in narrow structural spaces such as ships.
