Abstract
The invention provides a universal protective seal plug for a pipe hole. The universal protective seal plug for the pipe hole comprises two sets of plugging modules which are formed by being assembled in a cross-overlap mode; each plugging module is a semicircular cylinder, and the plugging modules are assembled in a butt-joint mode to form a cylindrical structure used for plugging. Sub-rings with different specifications are contained in the plugging modules and connected in a sleeving mode. When needing to plug a cable with a certain specification, the cable installation personnel only need to find out the sub-ring corresponding to the specification of the cable and then cut the connecting portion, on the inward side, of the sub-ring. The semicircular annular thin layer connecting structures among the sub-rings can be cut quickly and conveniently. Only one ends of the separated sub-rings which are connected in an overlapping mode need to be connected, and when plugging is performed, the close connection among the sub-rings can be achieved due to the existence of the connecting portions. By adopting the universal protective seal plug for the pipe hole, construction can be performed only needing to cut one end of the connecting portion and without needing to cut two ends or even the side face structure of the whole seal plug, and operation is easy and convenient.
Description
Technical field
The present invention relates to the accessory of buried cable protective conduit, the general exclusion seal plug of more particularly to a kind of pore.
Background technology
In underground, riverbed or when there are irrigation canals and ditches etc. to install cable, need guiding through wall and the ground such as get in, so that right
Blocked through at wall, to avoid sewage, poison etc. from entering inside wall by cable channel hole.And traditional cable sleeve pipe
Closure, using the hard materials such as cement, waterproof clay block, construction inconvenience, not reproducible use, and cable operation send out
Easily rupturable leak when raw vibrations or movement, as the different outside diameters of cable is different, various closure, the closure of reserved and through wires hole are
Separate, closure diameter can not be adjusted during construction at any time, difficulty of construction is increased, delayed construction speed.And Authorization Notice No.
In for the utility model patent of CN201011702Y, a kind of general diameter sealing plug of pore is disclosed, as shown in figure 1, the pore
By arranging multiple different inner diameters, the concentric drums with gap are used as cable retainer ring to general diameter sealing plug each other, put
During line, the cylinder less than the cable size for needing is removed using guarded blade utility knife, makes sealing-plug reach internal diameter variable, general.But it is this
Using relatively complicated, particularly in direct requirement threading, needs cut open general sealing-plug first in sealing-plug two ends expansion circle
Different cables fixes the connection of interannular, then cuts sealing-plug open so that cable is filled in wherein from side, and installation process is more multiple
It is miscellaneous.
The content of the invention
