Technical Field

The present invention relates to a pipe box for two-sided open type wire distribution, and more particularly, to a pipe box for two-sided open type wire distribution, which has a simple structure, facilitates the wiring work, and facilitates the manufacture and assembly of the box body.

Background

Generally, a wire distribution box is installed or buried in a wall surface, a ceiling, or the like during construction of a building, and switches the distribution direction of wires to a desired direction or pulls the wires to the indoor side at an appropriate position. An example of the above-described tube box is described in the drawings as follows:

as shown in fig. 1, a conventional distribution box 10 includes a box 11 having an inner space 12 of a predetermined size and a cover 13 coupled to the box 11, wherein an inlet 14 and an outlet 15 for allowing a cable C to be introduced and discharged are formed at both sides of the box 11, and an opening 16 for opening and closing the cover 13 is formed at one side.

In addition, a guide wheel (20) is arranged on the inner space (12) near the leading-in opening (14) and the leading-out opening (15), and the guide wheel (20) has rolling motion under the state that the cable (C) is contacted in the wiring process, so that the cable (C) can be smoothly inserted or pulled out.

In order to install these guide wheels (20) on the box body (11), the first and second shaft protrusions (17, 18) protruding into the inner space are formed on the upper and lower parts of the box body (11); the guide wheel (20) is made into a small roller group which is combined with a plurality of rollers (22) on a wheel shaft (21), and a combining hole (19) is required to be additionally processed and manufactured in order to install the guide wheel (20) on the shaft protrusions (17, 18).

However, in the case of the conventional case 11, in which the case is opened and closed only by the upper cover plate 13 in the case of bottom sealing, in order to form the coupling holes 19 in the shaft protrusions 17, 18, the second shaft protrusion 18 at the lower portion is continuously subjected to hole machining or tapping by penetrating the first shaft protrusion 17 with a cutting tool in a state where the cover plate 13 is opened; at this time, since the cutting edge of the cutting tool is shorter than the specification (height) of the case (11), the body of the cutting tool is interfered by the first shaft projection (17) in the process of processing the second shaft projection (18) at the lower part of the case (11) by the cutting edge, and therefore, the body part with relatively large diameter is inserted into the hole processed on the first shaft projection (17), and the processing defect caused by the damage of the processing hole is great.

In addition, since the coupling holes (19) are formed in the shaft protrusions (17, 18), and the first shaft protrusion (17) and the second shaft protrusion (18) are in a vertically separated state, the cutting tool penetrates the first shaft protrusion (17) and then enters the second shaft protrusion (18) in an idle state, which may not only cause a tool damage in the process of penetrating a discontinuous workpiece, but also cause a reduction in the dimensional accuracy of the first shaft protrusion (17) and the second shaft protrusion (18) due to the manufacturing characteristics of a case (11) usually made of a casting, thereby causing a difficulty in machining.

Detailed Description

The above objects, features and advantages of the present invention will be further apparent from the following detailed description. The following is illustrated on the basis of drawings which show possible embodiments of the invention:

fig. 2 to 12 are drawings of various embodiments of the present invention. As shown in fig. 2, the piping box 30 of the present invention is integrally formed with a box body 31 of a predetermined size, a first lid 37 and a second lid 38 coupled to both surfaces of the box body 31, and projecting connectors 47 and 48 connecting the first pipe P1 and the second pipe P2 to both sides thereof, and fastening bolts 50 fixing the pipes P1 and P2 are connected to the connectors 47 and 48.

Since the piping box 30 of the present invention is constructed such that the box main body 31 is open on both sides and is constructed to be inserted between the pipe bodies P1, P2 extended to a predetermined length so as to pass the cable C such as an electric wire, it can be manufactured by various methods without being limited to a molding method such as casting or die casting, and the detailed composition and operation of the present invention will be described below with reference to fig. 3 to 5:

as shown in fig. 3, the box main body 31 of the present invention has an internal space 32 of a predetermined size formed therein, an inlet 33 and an outlet 34 are formed on both sides of the internal space 32, and the connectors 47 and 48 are extended to a predetermined length, and a coupling hole 49 for the fastening bolt 50 is formed on an outer circumferential side of the connectors 47 and 48.

In addition, the box main body 31 of the invention is provided with a first opening 35 which opens one side of the internal space 32, a second opening 36 which opens the other side of the internal space 32 and corresponds to the first opening 35; the first cover 37 and the second cover 38 are detachably connected by a bolt B or the like in order to open and close the first opening 35 and the second opening 36.

A guide wheel 60 capable of guiding the cable C is provided on the periphery of the inlet 33 and the outlet 34 on the inner space 32 of the box main body 31; to attach the guide wheel 60, a wheel coupling portion 39 protruding into the internal space 32 is formed on the inner wall surface of the case main body 31.

The wheel coupling portion 39 is composed of a first coupling protrusion 40 positioned on the first opening 35 side and a second coupling protrusion 41 positioned on the second opening 36 side and corresponding to the first coupling protrusion 40, and the coupling protrusions 40 and 41 are formed with a notch groove 42 opened at the side surface and are connected to the guide wheel 60 by sandwiching the guide wheel.

In this case, the guide wheel 60 may be fixedly installed in a state where the coupling piece 63 is inserted into the notch groove 42, by coupling a rotatable roller 62 to a wheel shaft 61 having a certain length and including a plate-shaped coupling piece 63 coupled to the wheel shaft 61 and extending to one side of the roller 62.

As shown in fig. 4, in the piping box 30 of the present invention, when it is attached to a wall surface, a ceiling or the like in a state where the pipe bodies P1 and P2 are connected to each other and a cable is passed through the inside thereof during construction, the second cover plate 38 on the back surface of the box main body 31 in contact with the installation surface of the installation site is closed, the first cover plate 37 on the front surface is opened, and the cable C is manually transferred.

In the present invention, the guide roller 60 contacts the cable C during the distribution work of the manual transmission cable C, so that the cable C is smoothly pulled and the damage of the protective layer and the like during the stretching process of the cable C can be prevented.

As shown in fig. 5, after the wiring operation is completed, the first cover 37 is coupled to the box main body 31 to close the internal space 23 of the box main body 31 through which the cable C passes, and the first cover 37 can be opened to perform maintenance operations such as replacement or inspection of the cable C in the future.

In addition, in the case main body 31 of the present invention, connectors 47 and 48 extending the inlet 33 and the outlet 34 are integrally formed, and when the end portions of the first pipe P1 and the second pipe P2 are inserted into the connectors 47 and 48, a fastening bolt 50 is connected to the connection hole 49 to press and fasten the outer peripheries of the pipes P1 and P2, so that the case main body 31 of the connector integrated type is convenient in manufacturing and assembling operations because it is not necessary to additionally load the connectors for connecting the pipes P1 and P2, or it is not necessary to form a screw thread at the end portions of the case main body 31 and the pipes P1 and P2, and it is possible to form a pressing groove G into which the end portion of the fastening bolt 50 is inserted into the pipes P1 and P2, thereby firmly maintaining the coupled state.

In the above example, it is explained that the guide wheel 60 is embedded in the box main body 31, and the other coupling methods except the above are explained as follows from fig. 6 to 8:

as shown in fig. 6, another coupling method of the present invention is that a guide wheel 60 is coupled to the case main body 31 and the second cover 38 at the same time, after a coupling protrusion 44 similar to the first coupling protrusion 40 is formed on the first opening 35 side of the case main body 31, a notch groove 46 is formed in the coupling protrusion 44, a coupling groove 45 is formed on the surface of the second cover 38 corresponding to the coupling protrusion 44, and both sides of a coupling piece 63 of the guide wheel 60 are respectively clamped and coupled.

As shown in fig. 7 and 8, another coupling method of the present invention is that, unlike the clamping coupling, a guide wheel 60 is axially coupled, holes penetrating vertically or groove-shaped shaft holes 43 are formed in the coupling protrusions 40 and 41, and the guide wheel 60 is provided without the coupling piece 63 so that both ends of the wheel shaft 61 can be directly coupled to the shaft holes 43.

Here, the present invention is provided with a structure in which the notch groove 42 or the shaft hole 43 is formed in the coupling protrusions 40 and 41 as described above and both sides of the box main body 31 are opened, and it is possible to process the second coupling protrusion 41 2 times by turning over the box main body 31 after 1 time of processing the first coupling protrusion 40, thereby providing convenience in processing.

The present invention as described above can be provided with various arrangements of the inlet 33 and the outlet 34, shapes of the box main body 31 itself, and the like, and the following will be described with reference to fig. 9 to 12:

as shown in fig. 9 a and b, the box main body 31 of the present invention may have an L shape or an inverted L shape with an inlet 33 and an outlet 34 at 90 degrees, and conventionally, such an L shape or an inverted L shape is separately manufactured, but the present invention has a structure in which both sides of the box main body 31 are opened, and the L shape or the inverted L shape can be realized by replacing the installation direction of the same product, and thus, the box main body 31 having no directivity can be manufactured.

As shown in fig. 10 a and b, the box main body 31 of the present invention may have a T-shaped or cross-shaped structure in which the number of the inlet 33 or the outlet 34 is plural, and in this case, the number and arrangement of the guide wheels 60 installed in the box main body 31 are natural.

As shown in fig. 11 a and b, the box body 31 has a circular cross-sectional shape, and the inlet 33 and the outlet 34 may be arranged at 90 degrees or 180 degrees; as shown in fig. 12, an elbow-shaped curved portion 51 having a constant curvature and extending from the inlet 33 to the outlet 34 is formed in the internal space 32 of the box main body 31.

Here, as shown in fig. 12, when the case main body 31 itself has an elbow shape and the curved portion 51 having a constant curvature is formed in the internal space 32, it is preferable that the curvature is normalized so as to be turned toward the lead-out opening 34 when the cable C is inserted from the outside; in this case, when the box main body 31 is mounted, the covers 37 and 38 are mounted in a sealed state, and even if the cable C is not pulled manually in a state where the first cover 37 of the box main body 31 is opened, the cable C can be automatically switched in a state where the cable C is inserted from the outside, thereby providing convenience in the wiring work.

On the other hand, in the case of the case body 31 of a circular shape shown in fig. 11, the curved portion 51 having a constant curvature is formed in the internal space 32, and in the case of such a curved portion 51, when the cable C is inserted from the outside, it is difficult to change the direction of the cable C toward the lead-out opening 34 side, and only the case body 31 of a circular cross section can be selectively applied depending on the installation position or the environment.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications and changes may be made without departing from the technical idea of the present invention.
