Abstract
The utility model relates to a cable equipment technical field specifically is a nuclear level terminal box. Including box body and the upper cover that precision casting formed, the upper cover passes through fastening screw to be installed on the box body, is provided with two at least cylinder internal threads that are used for connecting the rigidity steel pipe on the box body, forms the awl post cooperation with the circular cone external screw thread of rigidity steel pipe, and all internal screw hole apertures of cylinder equal, and all edges and corners of box inner chamber are the fillet. The utility model has the advantages that the cylindrical internal thread and the conical external thread of the rigid steel conduit form a conical column matching, and the installation is easier on the premise of ensuring the tight and rigid connection; the threaded hole of the cylindrical internal thread is designed in an isometric structure, so that the cable can be effectively prevented from being scratched, and the wire drawing is time-saving and labor-saving; the inner cavity of the box body adopts a smooth full-round angle structure design, so that the friction of the cable in and out is reduced, and the cable is not damaged.
Description
Technical Field
The utility model relates to a cable equipment technical field specifically is a nuclear level terminal box.
Background
At present, the existing cable outlet box for the cable in China has small internal space, wastes time and labor for wire drawing, easily causes damage to the cable during wire drawing, and has short service life, complex structure and difficult installation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem to provide a can effectively prevent the fish tail cable, act as go-between labour saving and time saving, simple structure's nuclear level terminal box.
The utility model provides a problem, the technical scheme who adopts is:
the utility model provides a nuclear level terminal box, includes box body and the upper cover that precision casting formed, and the upper cover passes through fastening screw to be installed on the box body, is provided with two at least cylinder internal threads that are used for connecting the rigidity steel pipe on the box body, forms the awl post cooperation with the circular cone external screw thread of rigidity steel pipe, and all cylinder internal thread screw hole apertures equal, and all edges and corners of box body inner chamber are the fillet.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
① the internal thread of the cylinder and the external thread of the cone of the rigid steel conduit form a cone-column match, which is easier to install on the premise of ensuring tight and rigid connection.
② equal-diameter structure design of the threaded hole of the cylindrical internal thread can effectively prevent the cable from being scratched, and the pull wire is time-saving and labor-saving.
③ the inner cavity of the box body adopts a smooth full round angle structure design, reduces the friction of the cable in and out, and does not damage the cable.
Preferably, the present invention further provides:
the upper cover is of a dome structure, so that the strength of the box body and extra wiring space are increased.
A chloroprene rubber pad is arranged between the box body and the upper cover, so that the sealing performance of the pull line box is improved.
Drawings
Fig. 1 is a schematic front view structure diagram of an embodiment of the present invention;
fig. 2 is a schematic top view of the embodiment of the present invention;
FIG. 3 is a schematic side view of an embodiment of the present invention;
in the figure: a box body 1; a fastening screw 2; a chloroprene rubber pad 3; an upper cover 4; a fillet 5; a dome structure 6.
The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1, fig. 2, fig. 3, a nuclear level terminal box, box body 1 and upper cover 4 that form including precision casting, upper cover 4 passes through fastening screw 2 to be installed on box body 1, is provided with two cylinder internal threads that are used for connecting the rigidity steel pipe on the box body 1, constitutes the awl post cooperation with the circular cone external screw thread of rigidity steel pipe, and all cylinder internal thread screw hole apertures equal, and all edges and corners of the 1 inner chamber of box body are fillet 5.
The upper cover 4 is in a dome structure 6, which increases the overall strength and extra wiring space.
A chloroprene rubber pad 3 is arranged between the box body 1 and the upper cover 4, and the sealing performance of the pull line box is improved.
The whole hot dip galvanizing treatment of the pull wire box prolongs the service life.
The utility model has the advantages that the cylindrical internal thread and the conical external thread of the rigid steel conduit form a conical column matching, and the installation is easier on the premise of ensuring the tight and rigid connection; the threaded hole of the cylindrical internal thread is designed in an isometric structure, so that the cable can be effectively prevented from being scratched, and the wire drawing is time-saving and labor-saving; the inner cavity of the box body 1 adopts a smooth full-round angle structure design, so that the friction of the cable in and out is reduced, and the cable is not damaged.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
