Description
Technical Field
The utility model belongs to the domestic appliance field especially relates to an electrician's end box for ceiling.
Background
In the construction process of floor, for convenience of electric appliances such as electric lamps and ceiling fans on the ceiling, when the floor is poured, the plastic pipe for threading and the electrician bottom box are embedded in the ceiling, the current common practice is to nail the electrician bottom box on a pouring template, but because a plurality of steel bars are arranged in the ceiling, in the construction process, the steel bars are easily interfered with the plastic pipe, so that the electrician bottom box moves up and down, the current electrician bottom box cannot move after being nailed on the template, and because the current electrician bottom box is hollow, when concrete is poured, the concrete easily enters the electrician bottom box, when the template is removed, the time is required to be spent on cleaning the inside of the bottom box, therefore, the electrician bottom box for the ceiling is required, and the bottom box embedding construction on the ceiling is convenient to carry out.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an electrician's end box for ceiling can solve prior art awkward problem.
The utility model discloses a following technical scheme can realize.
The utility model provides a pair of electrician's end box for ceiling, including the cotton pad of bubble, base, movable shell, pedestal mounting stacks up at the cotton pad of bubble, and movable shell lower part suit is on base upper portion, and the base passes through the steel nail on the pouring template, and the steel nail penetrates and pricks on the pouring template from the cotton pad of bubble, base and movable shell are connected with the steel nail through the side ear, the cotton pad middle part of bubble is equipped with the arch, and the arch is filled inside base and movable shell.
The protrusion is provided with a contraction section which is positioned in the middle of the protrusion, and the side surface of the contraction section is wavy.
The lower part of the base is adhered to the upper part of the foam pad.
The upper part of the base is inserted into the lower part of the movable shell by 3cm to 5cm and is connected with the movable shell in a sliding way.
And an annular groove is arranged in the middle of the steel nail, and the distance between the annular groove and the steel nail is 2cm to 3 cm.
The foam pad has a thickness of 1cm to 2 cm.
The beneficial effects of the utility model reside in that: through filling the bubble cotton in base and activity shell, and the articulated department intermeshing of base and activity shell can prevent during concrete infiltration base and activity shell when the pouring floor, base and activity shell keep sliding connection simultaneously, can adjust from top to bottom when activity shell and reinforcing bar take place to interfere, improve the flexibility.

Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1 to 3, an electrician's bottom box for ceiling, includes bubble cotton pad 1, base 2, activity shell 3, base 2 installs on bubble cotton pad 1, and 3 lower part suits of activity shell are on 2 upper portions of base, and base 2 is on the pouring template through 4 nails of steel nail, and steel nail 4 penetrates and pricks the pouring template from bubble cotton pad 1 on, base 2 and activity shell 3 are connected with steel nail 4 through side ear 5, bubble cotton pad 1 middle part is equipped with arch 6, and arch 6 is filled inside base 2 and activity shell 3.
When the steel nail hammer is used, the steel nail 4 penetrates through the side lug 5 on the base 2 and the movable shell 3 and then pierces the foam pad 1, the steel nail 4 is knocked into a pouring template, when the movable shell 3 or an embedded pipeline interferes with steel bars, the movable shell 3 needs to be lifted, the movable shell 3 can be properly pulled up to avoid interference, the protrusion 6 expands along with the lifting of the movable shell 3 to avoid a gap between the base 2 and the movable shell 3 to prevent concrete from permeating, the protrusion 6 is filled in the base 2 and the movable shell 3 during pouring, the lower part of the base 2 is adhered to the upper part of the foam pad 1 to prevent the concrete from permeating into the interior, after the pouring is finished and the template is removed, the base 2, the movable shell 3 and the steel nail 4 are all embedded into a ceiling, after the template is removed, the tip of the steel nail 4 leaks out, because the middle part of the steel nail 4 is provided with the annular groove 8, after the steel nail 4 is knocked from the lateral direction by using, the steel nail 4 breaks at the annular groove 8, and then the protrusions 6 in the base 2 and the movable shell 3 can be dug out by hands, so that space is conveniently reserved for installing electric wires and electric equipment.
Be equipped with shrink section 7 on arch 6, shrink section 7 is located 6 middle parts of arch, and shrink section 7 side is wavy for protruding 6 can be the great deformation volume in back, be convenient for follow reciprocating of activity shell 3 and shrink, prevent that the concrete from permeating base 2 and activity shell 3 middle parts in a large number, protruding 6 can be a whole, also can be formed by the cotton concatenation of polylith bubble, adjusts according to the site conditions when facilitating the use.
The lower part of the base 2 is adhered to the upper part of the foam pad 1 through common glue, so that concrete is prevented from permeating from a gap between the lower part of the base 2 and the upper part of the foam pad 1.
3 lower parts 3cm to 5cm of movable shell are inserted to 2 upper portions of base to with 3 sliding connection of movable shell, make 2 upper portions of base insert 3 lower parts of movable shell after, make movable shell 3 can slide from top to bottom in certain extent, be convenient for adjust according to the construction conditions.
The middle of the steel nail 4 is provided with an annular groove 8, the distance between the annular groove 8 and the steel nail 4 is 2 cm-3 cm, the steel nail 4 is hard but brittle, and after the side face of the steel nail 4 is impacted, the steel nail is easy to break at the annular groove 8, so that the tip of the extended steel nail is broken, and construction is facilitated.
The thickness of the foam pad 1 is 1cm to 2cm, so that a groove is formed at the foam pad 1, and the foam pad is convenient for an electric appliance to be installed on a ceiling.
