Description

Building lead wire guide {POWER CABLE GUIDE FOR BUILDING}

The present invention relates to a lead-in wire guide of a building.

In general, an indoor switchboard is a device installed to supply or cut off electric power in a building, and is configured with built-in devices such as instruments, relays, switches, and safety devices for opening and closing electrical circuits or controlling electrical facilities.

As described above, since various hazardous parts with relatively high-voltage current flowing in the switchboard are closely installed in the internal space, it is necessary to have seismic resistance so that the hazardous parts can be safely maintained and stored without being damaged or deformed even by external shocks such as natural disasters. In addition to this, technology development to prevent water flowing along the distribution line (hereinafter referred to as 'incoming wire') from entering the switchboard is continuously being developed.

In particular, water such as rainwater may flow down and flow into the switchboard along the lead wire wired to the lead wire guide (tray) and connected to the switchboard, and a technology that can also prevent this is urgently required.

On the other hand, as is well known, the tray constitutes a plurality of supports supporting incoming wires. Since the pedestal is uniformly aligned at regular intervals, there is an irrationality in that the pedestal cannot be additionally reinforced even though it is necessary to support a relatively heavy incoming wire in a specific section and the incoming wire must be unstablely supported according to the existing structure. In addition, the incoming wire placed on the tray may have a difference in weight depending on the site situation, but even with this change, there is a limit to lowering efficiency because the standardized tray must be uniformly arranged. In addition, when a random incoming wire is withdrawn from the middle of the tray as needed, the interfering pedestal had to be forcibly cut in the drawing out section. In addition, depending on the site situation, the pedestal could rather interfere with the tray installation, so even in this case, the worker directly removed the pedestal or adjusted its position and welded it. However, since this response work is another factor that adds to the worker's work, an improvement plan was also urgently required.

Figure 5 is a perspective view showing a partially exploded view of the main tray configured in the incoming wire guide according to the present invention, Figure 6 is a perspective view showing a partially exploded view of the pedestal configured in the incoming wire guide according to the present invention, Figure 7 is It is a plan view sequentially showing how the pedestal of the main tray is mounted on the flange of the support.

2 and 5 to 7, the pedestal 113 configured in the main tray 110 in this embodiment includes a main body 1131 having opening grooves H3 formed on both side end surfaces, respectively, as described above. , Insertion and detachable insertion into the fitting groove 1113, formation of an engagement groove R on one side to engage the lower flange 1112, and withdrawal rod 1132a inserted into the opening groove H3 on the other side so as to be able to withdraw It is composed of a pair of grabpers 1132 and 1132' having handles 1132b protruding downward, and an elastic body 1134 inserted into the opening groove H3 to support the pull-out rod 1132a and support the elastic. do.

In this embodiment, the pedestal 113, which does not receive a separate external force, has a length greater than the distance between the pair of first supports 111 and 111' by the elastic force of the elastic body 1134. Therefore, in order to connect the pedestal 113 to the pair of first supports 111 and 111', the length of the pedestal 113 must be reduced to a length equal to or less than the distance between the pair of first supports 111 and 111'. Since the pedestal 113 is connected to both ends of the main body 1131 so that a pair of grabpers 1132 and 1132' can be drawn in and out, the length of the pedestal 113 is stretched.

More specifically, a fitting groove 1113 is formed in the lower flange 1112 of the first supports 111 and 111', and the grabpers 1132 and 1132' are inserted into the fitting groove 1113. interlock and bind together To this end, the width of the grabpers 1132 and 1132' should be less than the width of the fitting groove 1113, and in order to engage the lower flange 1112, the gripper 1132 and 1132' facing the lower flange 1112 An opening groove H3 is formed on one side so that the front end of the lower flange 1112 is inserted. As a result, the grabpers 1132 and 1132' inserted into the fitting groove 1113 engage the front end of the lower flange 1112 through the opening groove H3 to maintain a binding state, as well as insert into the fitting groove 1113. Since it is in a state, it maintains its position without moving.

Meanwhile, on the other side of the grabpers 1132 and 1132', a pull-out rod 1132a inserted into the opening groove H3 of the main body 1131 is formed. Accordingly, the grabpers 1132 and 1132' are drawn in and out of the main body 1131 to expand and contract the pedestal 113. Subsequently, an elastic body 1134 is installed in the opening groove H3 to elastically support the withdrawing/retracting rod 1132a. Therefore, when the operator presses the grabpers 1132 and 1132' and presses the pull-out rod 1132a into the opening groove H3, the elastic body 1134 is filled with elastic force, and the operator presses the grabper 1132 and 1132' When the pressure on is released, the elastic body 1134 elastically retracts the pull-out rod 1132a with the charged resilient force so that the grabpers 1132 and 1132' are separated from the body 1131.

Eventually, in order for the operator to mount the pedestal 113 on the first supports 111 and 111', as shown in (a) of FIG. 7, the grabper 1132 is inserted into the fitting groove 1113 of the lower flange 1112. 7 (b), insert the grabper 1132 into the fitting groove 1113 and press the grabper 1132 to the main body 1131. Therefore, as shown in (c) of FIG. 7, the pull-out rod 1132a of the grabper 1132 is inserted into the opening groove H3 of the main body 1131, and the grabper 1132 and the main body 1131 interact with each other. While approaching, the length of the pedestal 113 is reduced to be located between the pair of first supports 111 and 111'. In addition, the grabper 1132 inserted into the fitting groove 1113 engages the lower flange 1112 of the fitting groove 1113 section with the engaging groove R to restrain the vertical movement of the pedestal 113. In addition, since the grabper 1132 is inserted into the fitting groove 1113, the left and right movement of the pedestal 113 is restricted.

Through the above structure, the main tray 110 can adjust the installation position of the pedestal 113 according to the site situation and the adjustment of the incoming wire support position, and can reinforce or reduce the number of pedestals 113 as necessary.

Meanwhile, since the grabper 1132 constitutes a handle 1132b protruding downward, the operator moves the grabper 1132 relative to the main body 1131 while holding the handle 1132b under the main tray 110. . Accordingly, the operator expands and contracts the length of the pedestal 113 through the movement of the pair of grabpers 1132 to separate or install the pair of first supports 111 and 111'.

8 to 10, the restraining mechanism 114 according to the present invention rotatably penetrates the intersection of the first insertion groove 1131a and the second insertion groove 1131b, ascends and descends, and protrudes downward. A handle bar 1141 fixed to the top of the handle bar 1141 and an axis bracket 1142 that is inserted and detached from the handle bar 1141 in the intersection section according to the ascending and descending of the handle bar 1141 and seated, and the axis bracket 1142 rotates Possibly horizontally penetrating, protruding oppositely to both sides with respect to the shaft bracket 1142, and removably seated in the first insertion groove 1131a and the second insertion groove 1131b according to the rotational position of the shaft bracket 1142, It consists of a fence 1143 forming a 'c' shape so as to surround the incoming wire C seated on the pedestal 113 so that it can be drawn in and out.

In this embodiment, the fence 1143 forms a 'c' shape to have an opening through which the incoming wire C can be drawn in and out, so the front and rear surfaces of the main body 1131 are shown in (a) of FIGS. 8 and 10. When the first insertion groove 1131a configured also faces the fence 1143 and both ends of the fence 1143 are downward, the entire body of the fence 1143 is inserted into the first insertion groove 1131a. Since the first insertion groove 1131a is intended to completely accommodate the fence 1143, it is preferable that the fence 1143 inserted into the first insertion groove 1131a does not protrude from the outer surface of the body 1131.

Since the first insertion groove 1131a and the second insertion groove 1131b configured in the main body 1131 of the pedestal 113 cross in a cross shape, the operator manipulates the handle 1141 to obtain a Likewise, the fence 1143 may face the second insertion groove 1131b. Subsequently, since the fence 1143 is rotatably connected to the shaft bracket 1142, both ends of the fence 1143 can be raised upward as shown in FIG. 10(c) through manipulation of the operator.

After the above process, the operator manipulates the handle 1141 to lower the shaft bracket 1143, and inserts the central portion of the fence 1143 including the shaft bracket 1143 into the second insertion groove 1131b as shown in FIG. As a result, both ends of the fence 1143 protrude from the upper surface of the main body 1131 of the pedestal 113, and through this, the incoming wire C seated on the pedestal 113 is restrained within the fence 1143 without separation.

In this embodiment, the fence 1143 is composed of a first side portion 1143a and a second side portion 1143b, and the first side portion 1143a constitutes an axle shaft A that rotatably penetrates the shaft bracket 1143. And, the second side portion 1143b constitutes an insertion hole engaged and fixed with the end of the shaft (A). Therefore, the fence 1143 can be rotated 360 degrees around the axis A without interference with the handle 1141 due to the opening.
