A type of hoisting junction box for electromechanical installation

Abstract

This utility model provides a suspended junction box for electromechanical installation, including a splicing box body suspended on a floor slab to house electrical wires. The splicing box body includes a top plate connected to the floor slab, a bottom plate located below the top plate, and four movable plates arranged in a rectangular array and slidably between the top and bottom plates, with adjacent movable plates arranged perpendicularly. Each movable plate has a through mounting cavity. When the number of wires is small, an extension plate can be stored inside the movable plate, where two extension plates are joined to form a second circular hole structure. When this second circular hole structure is aligned with the first through hole, power wires can pass through. If the number of wires is large, the extension plate can be stretched out from within the movable plate—after stretching, the movable plate and the extension plate together form the first through hole and two independent second semi-circular holes, allowing multiple wires to pass through different holes, effectively preventing wires from tangling.

Description

Technical Field

[0001] This utility model relates to the field of junction box installation technology, specifically a hoisting junction box for electromechanical installation. Background Technology

[0002] In home renovation, junction boxes are one of the electrical accessories. Because the wires used in renovation run through conduits, junction boxes are used as transitions at the joints of the wires (such as when the wire is long or the conduit needs to turn a corner). The conduit connects to the junction box, and the wires inside the conduit are connected in the junction box, which serves to protect and connect the wires. This is what a junction box is.

[0003] During the construction of electromechanical installation projects, junction boxes that need to be suspended in the ceiling or other locations are usually suspended in the air by fixing and connecting conduits to the junction boxes. However, most junction boxes on the market currently have fixed sizes, which cannot be flexibly adjusted according to the number of lines. When there are many lines, the junction box space is insufficient, while when there are few lines, it is wasteful, resulting in the need to customize junction boxes of different sizes according to actual needs. This not only increases the complexity of production and procurement, but also significantly drives up the overall cost. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting junction box for electromechanical installation, which aims to solve the problem that the size of the junction box in the prior art is not convenient to adjust according to the needs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the electromechanical installation hoisting junction box includes a splicing box body hoisted on the floor slab to house the wires inside the splicing box body;

[0006] The splicing box includes a top plate connected to the floor slab, a bottom plate located below the top plate, and four movable plates arranged in a rectangular array and slidably between the top plate and the bottom plate, with adjacent movable plates arranged perpendicularly to each other.

[0007] The movable plate has a transparent mounting cavity, and two extension components slide within the mounting cavity. The movable plate has a first through hole through which the power supply line passes, and the extension components have a second semi-circular hole through which the power supply line passes.

[0008] When the two extended components are spliced ​​together, the two second semicircular holes can be spliced ​​together to form a second circular hole structure. When the second circular hole structure corresponds to the first through hole, the power supply line can pass through.

[0009] Preferably, the extension assembly includes an extension plate that slides within the mounting cavity and a guide strip fixed to the top of the extension plate;

[0010] The upper end of the mounting cavity is provided with a through limiting hole, which is connected to the mounting cavity vertically.

[0011] The guide bar guides the sliding motion within the limiting hole;

[0012] The inner walls of the limiting hole are fixed with first retaining rings at both ends, and the guide strip is fixed with second retaining rings at both ends. When the first retaining rings and the second retaining rings abut against each other, the guide strip can be prevented from dislodging from the limiting hole.

[0013] Preferably, the joints of the extension plates in two adjacent movable plates are arranged vertically.

[0014] The same vertical rod extending in the vertical direction is fixed at the vertical position of two adjacent extension plates.

[0015] Preferably, the second semicircular hole is opened on one side of the two extension plates opposite each other. When the extension plates are pulled out from the movable plate, the wires can be laid in the first through hole and the two second semicircular holes respectively.

[0016] Preferably, the movable plate is fixedly connected to the two extension plates by a locking assembly.

[0017] Preferably, the locking assembly includes a bolt groove formed on the movable plate and communicating with the mounting cavity, a plurality of spaced positioning holes formed on the extension plate, and a bolt passing through the positioning holes and threadedly adapted to the bolt groove.

[0018] When the extension plate is pulled out from the movable plate, the positioning hole and the bolt groove correspond to each other, and the bolt passes through the positioning hole and the bolt groove for threaded connection.

[0019] Preferably, the bottom of the top plate and the top of the bottom plate are provided with limiting grooves, and the upper and lower ends of the movable plate are fixed with limiting sliders, which are guided and slid within the limiting grooves.

[0020] Both the limiting groove and the limiting slider have a convex shape in cross-section.

[0021] Preferably, the top plate has a threaded hole that is open at both the top and bottom, and a connector extending in the vertical direction is fixed to the lower side of the floor slab, with the lower end of the connector being threadedly connected to the threaded hole.

[0022] The beneficial effects are: 1. When the number of lines is small, the extension plate can be stored inside the movable plate. At this time, the two extension plates are spliced ​​together inside the movable plate to form a second circular hole structure. When this second circular hole structure is aligned with the first through hole, the power lines can pass through. If the number of lines is large, the extension plate can be stretched out from inside the movable plate. After stretching, the movable plate and the extension plate together form the first through hole and two independent second semi-circular holes, thereby achieving the effect of multiple lines passing through different holes, effectively avoiding the situation of lines tangling together.

[0023] 2. By setting a locking component, it can be ensured that the extension plate forms a stable locked state with the moving plate after it is fully extended. This component can precisely limit the extension position of the extension plate, preventing it from unexpectedly shrinking due to external force or its own elasticity, and avoiding abnormal expansion caused by structural deformation due to excessive force, thereby maintaining the reliability and stability of the line shunt structure.

Detailed Implementation

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0031] In this embodiment, a hoisting junction box for electromechanical installation is mainly used to adjust the size of the junction box according to the number of lines so that the junction box can be used in different situations. When there are few lines, the extension plate 501 can be put into the mounting cavity 4 to form a smaller junction box. When there are many lines, the extension plate 501 can be extended out from the mounting cavity 4 to form more holes for the lines to pass through.

[0032] In this embodiment, the suspended junction box includes a splicing box body suspended on the floor slab to house the wires inside the splicing box body. In this embodiment, the top plate 1 has a threaded hole that is open from top to bottom. A connector 13 extending in the vertical direction is fixed on the lower side of the floor slab. The lower end of the connector 13 is threadedly connected to the threaded hole, and the top of the connector 13 is connected to the floor slab by bolts to suspend the splicing box body.

[0033] like Figure 1 and Figure 4 As shown, the movable plate 3 can move between the top plate 1 and the bottom plate 2 to adjust the space of the splicing box according to the wiring conditions.

[0034] Specifically, the splicing box includes a top plate 1 connected to the floor slab, a bottom plate 2 located below the top plate 1, and four movable plates 3 arranged in a rectangular array and slid between the top plate 1 and the bottom plate 2. The adjacent movable plates 3 are arranged perpendicularly to each other, so that the movable plates 3 are rectangular spaces after being expanded or shrunk, so that the lines can pass through.

[0035] Limiting grooves 12 are provided at the bottom of the top plate 1 and the top of the bottom plate 2. Limiting sliders are fixed at both the upper and lower ends of the movable plate 3. The limiting sliders slide within the limiting grooves 12. When the movable plate 3 moves, it can slide within the limiting grooves 12 through the limiting sliders, thus guiding the movable plate 3. The cross-sectional shape of the limiting grooves 12 and the limiting sliders are both convex structures. The convex structure allows the movable plate 3 and the bottom plate 2 to be suspended from the top plate 1, preventing them from falling.

[0036] like Figures 1-3 As shown, the movable plate 3 has a transparent mounting cavity 4. Two extension components 5 are guided and slidable within the mounting cavity 4. The movable plate 3 has a first through hole 6 through which the power supply line passes. The extension components 5 have a second semi-circular hole 7 through which the power supply line passes. This allows the line to pass through the first through hole 6 and the two second semi-circular holes 7 respectively. Alternatively, when the two extension components 5 are spliced ​​together, the two second semi-circular holes 7 can be spliced ​​together to form a second circular hole structure. When the second circular hole structure corresponds to the first through hole 6, it forms a single hole to allow the wire to pass through. By setting the extension components 5, the internal space of the splicing box can be adjusted according to the number of lines, thereby improving the applicability of the splicing box.

[0037] Specifically, the extension component 5 includes an extension plate 501 that slides within the mounting cavity 4 and a guide strip 502 fixed to the top of the extension plate 501. A through-hole locating hole 8 is provided at the upper end of the mounting cavity 4. In this embodiment, the locating hole 8 has a convex cross-sectional shape and is vertically connected to the mounting cavity 4. The guide strip 502 slides within the locating hole 8. When the extension plate 501 extends or retracts, the guide strip 502 can move along the extension direction of the locating hole 8 to limit the extension plate 501 to the left and right. A first retaining ring is fixed at both ends of the inner wall of the locating hole 8, and a second retaining ring is fixed at both ends of the guide strip 502. The first and second retaining rings abut against each other, preventing the guide strip 502 from disengaging from the locating hole 8.

[0038] like Figure 1 and Figure 2 As shown, the joint of the extension plates 501 in two adjacent movable plates 3 is set vertically; the vertical joint of two adjacent extension plates 501 is fixed with the same vertical rod 10 extending in the vertical direction. When the extension plate 501 moves, it can drive the corresponding vertical rod 10 to move together, so that the movable plate 3 and the extension plate 501 are linked together, avoiding the twisting of the splicing box when it expands or shrinks.

[0039] like Figure 1 As shown, when the extension plate 501 is pulled out from the movable plate 3, the wires can be laid in the first through hole 6 and the two second semicircular holes 7 respectively.

[0040] Specifically, the second semicircular hole 7 is opened on one side opposite to the two extension plates 501.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, the movable plate 3 is fixedly connected to the two extension plates 501 via the locking assembly 11.

[0042] Specifically, the locking assembly 11 includes a bolt groove 1101 formed on the movable plate 3 and communicating with the mounting cavity 4, a plurality of spaced positioning holes 1102 formed on the extension plate 501, and bolts 1103 passing through the positioning holes 1102 and threadedly mating with the bolt groove 1101; when the extension plate 501 is pulled out from the movable plate 3, the positioning holes 1102 and the bolt groove 1101 correspond to each other, and the bolts 1103 pass through the positioning holes 1102 and are threadedly connected to the bolt groove 1101.

[0043] In this embodiment, when the extension plate 501 needs to be stretched, the bolt 1103 can be removed from the bolt groove 1101 first, and then the extension plate 501 can be pulled.

[0044] Working principle: In use, the splicing box body and the floor slab are first connected by the connector 13 to suspend the splicing box body. Then, when there are fewer wires, the bolt 1103 is removed from the bolt groove 1101. Then, the limiting slider on the moving plate 3 slides along the limiting groove 12 to shrink the splicing box body to the minimum space. After shrinking, the bolt 1103 is threaded into the bolt groove 1101. At this time, the extension plate 501 is put into the mounting cavity 4. The two second semi-circular holes 7 are spliced ​​to form a second circular hole structure. When the second circular hole structure corresponds to the first through hole 6, a single hole is formed to allow the wires to pass through.

[0045] If there are many lines, the bolt 1103 can be removed from the bolt groove 1101, and then the extension plate 501 can be pulled outward. When the moving plate 3 moves, it can be guided to slide in the limiting groove 12 by the limiting slider, which plays a guiding role for the moving plate 3. After the extension plate 501 is expanded, the bolt 1103 is threaded to the bolt groove 1101. At this time, the lines pass through the first through hole 6 and the two second semi-circular holes 7 respectively, thereby achieving the effect of multiple lines passing through different holes, effectively avoiding the situation of lines tangling together.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
