Detailed Description

The present invention is described in detail below with reference to the drawings, which are intended to illustrate preferred embodiments of the present invention and not to limit the scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations and positional relationships based on the orientations and positional relationships shown in the drawings, and are only used for describing the present invention and simplifying the description, but do not indicate or imply that the device or the element to be referred to must have a specific orientation and a specific orientation configuration and operation, and thus, should not be construed as limiting the present invention.

In an embodiment, the novel secondary masonry junction box plugging and closing device comprises a shell 7 with a quadrangular frustum pyramid shaped inner cavity and an end cover 11 arranged at the top end of the shell 7, that is, the outer surface of the shell can be in various shapes, such as a frustum pyramid shape, a square shape, a cylindrical shape or a circular truncated cone shape, as long as the inner cavity of the shell is in the quadrangular frustum pyramid shape, the upper end and the lower end of the shell 7 are open, and the shape and the size of the inner edge of the upper end opening of the shell 7 are matched with the shape and the size of the outer edge of the outer port 1 of the junction box, as shown in fig. 3, when the novel plugging and closing device is used, the matched shape and the size mean that the outer edge of the outer port 1 of the junction box is abutted against the inner edge of the upper end opening of the shell 7, and theoretically form a sealing structure to prevent fillers from entering the junction box; the height of the shell 7 is the same as that of the convex wall surface of the junction box, the end cover 11 is provided with 2 through

holes

9, 2 through holes are opposite to 2 inner ear holes 6 in the junction box, the end cover 11 is connected with the inner ear holes 6 through bolts 10 penetrating through the through holes 9 and is tightly pressed on the upper end surface of the shell 7, the side wall of the shell 7 is also provided with a grouting funnel 16 penetrating through the interior of the shell, as shown in figure 3, when the terminal box is used, the terminal box is buckled outside a port of the convex wall surface of the junction box, so that an upper end opening of the shell 7 is tightly pressed between an outer port 1 of the junction box, as shown in figure 4, the end cover 11 is assembled, the outer port 1 of the junction box is further tightly pressed by the end cover 11, a relatively sealed space is formed between the shell and the junction box, so as to prevent slurry from entering the junction box, and fillers are injected into the shell through the grouting funnel 16, so as to close and seal the junction box, after molding, the utility model can be disassembled.

In a further embodiment, as shown in fig. 1, 3 and 4, the lower end of the side wall of the shell 7 is further coaxially provided with a first elastic rubber layer 13; although the effect of the previous embodiment can be achieved theoretically, since construction errors are difficult to avoid, the first elastic rubber layer 13 is arranged in the present embodiment, when the terminal box is used, if the height of the convex wall surface of the terminal box is smaller than a standard size, the shell 7 is pressed down by screwing the bolt 10, so that the first elastic rubber layer 13 is compressed and shortened, the outer port 1 of the terminal box can be abutted against the upper end opening of the shell 7, and the construction requirement is met.

In a further embodiment, as shown in fig. 5, the end surface of the end cap 11 facing the wall surface is further provided with a second elastic rubber layer 12; similarly, the outer port 1 of the terminal box and the upper end opening of the housing 7 cannot form a sealing structure due to the error of the size and shape of the terminal box, and the position which cannot be sealed is sealed by the second elastic rubber layer 12 in the embodiment.

In a further embodiment, as shown in fig. 5, the second elastic rubber layer 12 is matched with the outer edge of the outer port 1 of the junction box in shape and size; the matching means that the two are the same in size and shape, when the terminal box is used, the bolt 10 is screwed, and the second elastic rubber layer 12 presses the outer port of the terminal box to form a sealing structure.

In a further embodiment, as shown in fig. 3 and 4, the grouting hopper 16 has a rectangular parallelepiped structure.

In a further embodiment, as shown in fig. 1, the angle a between the inner surface of the side wall of the housing 7 and the outer wall surface of the housing is 135 °; in this embodiment, the housing is also in a quadrangular frustum pyramid structure, and the inner and outer surfaces are parallel to each other.

In a further embodiment, as shown in fig. 1, 3 and 4, the outer surface of the housing 7 is also formed into a quadrangular frustum pyramid shape.

This neotype theory of use:

during this novel use, as above, through the bolt of screwing, make the outer port 1 of terminal box offset with the upper end opening of casing 7, at this moment, second elastic rubber layer 12 compresses tightly the outer port of terminal box, constitute seal structure between the outer port of casing and terminal box, thereby the filler can't get into and constitutes the pollution in the terminal box, and simultaneously, first elastic rubber layer 13 compresses tightly the surface of wall body 15, make and constitute seal structure between wall body and the casing, prevent the hourglass thick liquid, fixed good back, can be through the filler of slip casting funnel 16 injection in to the casing, behind the filler shaping, pull down this neotype can.
