Description

Box of the default pre-buried special-purpose end

Technical field

The utility model relates to the box of the default pre-buried special-purpose end that is used to install supply socket, switch etc. in a kind of building industry.

Background technology

In building industry,, generally adopt box of the default pre-buried special-purpose end in building for the installation of supply socket, switch etc.Present box structure of the default pre-buried special-purpose end generally is square box body, is provided with the installing port that is used to install switch, socket at square box body, and sidewall is preset with removable installation through hole.Present default pre-buried special-purpose end box cement mortar in installation process penetrates in the end box easily, can influence the end box when serious can't use, pre-in addition pipe laying stays surplus residual head in end box, brought great inconvenience for later setting-out work, not only incur loss through delay time and duration, but also wasted human and material resources and financial resources.

The utility model content

Technical problem to be solved in the utility model provides a kind of box of the default pre-buried special-purpose end that cement mortar can not infiltrate in installation process, pre-pipe laying can not stay surplus residual head.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: box of a kind of default pre-buried special-purpose end, comprise end box body, it is characterized in that: the removable installation through hole of box body of the described end is provided with extension and takes over, on the installing port of box body of the described end, be provided with diaphragm seal, in box body of the described end, be filled with filler.

Adopt the box of the default pre-buried special-purpose end of technique scheme, extension is taken over the problem of staying surplus residual head in the end box that solved, simultaneously be provided with diaphragm seal at installing port, end box installing port is sealed, cement mortar can't be penetrated in the end box, be filled with filler in end box, this filler is the material of no building structure power such as foam, sponge, wood chip etc., even cement mortar infiltrates in the end box, also can easily residue in the end box be removed clean.

In sum, the utility model is that a kind of cement mortar can not infiltrate in installation process, pre-pipe laying can not stay surplus residual head and default pre-buried special use end box simple in structure, easily manufactured, dependable performance.
