Description

Technical Field

[0001] This utility model belongs to the field of home electrical accessories, and in particular relates to a multifunctional PVC-U concealed junction box. Background Technology

[0002] In home renovation, junction boxes are one of the electrical accessories. The conduit is connected to the junction box, and the wires inside the conduit are connected in the junction box, which serves to protect and connect the wires and ensure the safety of household electricity use.

[0003] The existing PVC junction boxes have the following problems:

[0004] First, the fixing point between the PVC junction box and the switch panel is flat. 95% of different types of switch panels on the market come with flat-head screws, making installation difficult. Normal installation requires additional self-tapping screws and external force to tighten them. This can easily damage the switch panel and potentially injure installation workers. Furthermore, it is time-consuming, labor-intensive, affects construction progress and aesthetics, and poses safety hazards.

[0005] Secondly, the punched holes on the side of the PVC junction box are about 1.2cm from the bottom of the junction box. The minimum distance between the two holes is 1.6cm and the maximum distance is 5.6cm. This results in deep and wide grooves during construction, which not only affects construction efficiency and aesthetics, but also makes it easy to hit the reinforcing steel, increasing the difficulty of construction and posing safety hazards.

[0006] Third, the knockout holes of existing PVC junction boxes are all single-hole designs, which can only be used for electrical conduits of the same diameter. On the one hand, the production cost is high and the product delivery cycle is long; on the other hand, the construction is complicated and inefficient, requiring multiple materials to meet the construction needs of different working conditions, and there is a lot of material waste, which affects the construction efficiency. Utility Model Content

[0007] In view of this, the present invention aims to propose a multifunctional PVC-U concealed junction box to solve the problems in the prior art where it is inconvenient to screw in flat-head screws at the connection between the junction box and the switch panel, the setting of the knock-out hole results in a deep and wide groove, and it can only be used for electrical conduits of the same diameter.

[0008] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0009] A multifunctional PVC-U concealed junction box includes a box body and two screw connection assemblies, the two screw connection assemblies being disposed on the inner walls of both sides of the box body;

[0010] The box has several knockout hole assemblies on its four side walls and bottom, and these knockout hole assemblies are connected to the inside of the box.

[0011] Furthermore, the top of the box body is provided with an open accommodating space.

[0012] Furthermore, the two screw connection assemblies are disposed within the accommodating space, and the two screw connection assemblies are disposed on the inner walls of both sides of the box body;

[0013] The screw connection assembly includes a rectangular post with rectangular through holes on both sides and an arc-shaped through hole in the middle. The inner diameter of the arc-shaped through hole gradually decreases from top to bottom. This arc-shaped through hole accommodates both self-tapping screws and flat-head screws. By adding curvature to the flat surface in existing technology, flat-head screws can be directly screwed in from the arc, avoiding the need for external force to drive them in. This reduces the consumption of manpower and resources and improves work efficiency.

[0014] Furthermore, each of the four side walls of the box is provided with two knockout hole assemblies, and the centers of the knockout hole assemblies on the four side walls are located on the same horizontal plane.

[0015] Furthermore, the knockout hole assemblies on the four side walls of the box are 0.8-1.5cm away from the top of the box.

[0016] Furthermore, the knockout hole assemblies on the four side walls of the box are 1cm away from the top of the box.

[0017] Reducing the distance between the knockout hole assembly and the top of the box aims to decrease the depth of the construction groove, avoid encountering steel bars during construction, increase construction difficulty, and make construction more convenient.

[0018] Furthermore, the distance between the two knockout hole assemblies on the side wall of the box is 0.8-2cm.

[0019] Furthermore, the two knockout hole assemblies on the side wall of the box are spaced 1 cm apart.

[0020] While ensuring proper installation of the cup comb, the distance between the two knockout hole components is reduced to minimize the groove width and improve construction efficiency.

[0021] Furthermore, the bottom of the housing is provided with two knockout hole assemblies, which are arranged diagonally. The purpose of the diagonal arrangement is to accommodate wires that are connected from different directions.

[0022] Furthermore, the knockout hole assembly includes a first wiring hole, a first wiring hole plate, a second wiring hole, and a second wiring hole plate, the diameters of the first wiring hole, the first wiring hole plate, the second wiring hole, and the second wiring hole plate decrease sequentially, and the first wiring hole, the first wiring hole plate, the second wiring hole, and the second wiring hole plate are concentrically arranged;

[0023] The first wiring hole is located on the box body. The first wiring hole plate is connected to the box body through several evenly distributed first connecting posts. The second wiring hole plate is connected to the first wiring hole plate through several evenly distributed second connecting posts.

[0024] The knockout hole assembly is designed with concentric unequal diameter holes, which can be used with cup combs of different diameters to meet the construction needs of different working conditions and make construction more convenient.

[0025] Compared with existing technologies, the multifunctional PVC-U concealed junction box of this utility model has the following advantages:

[0026] (1) The arc-shaped through hole described in this utility model can be used not only for self-tapping screws, but also for flat-head screws, so that flat-head screws can be screwed in directly from the arc, avoiding the problem that flat-head screws need to be screwed in with the help of external force, reducing the consumption of manpower and material resources, and improving work efficiency.

[0027] (2) This utility model reduces the distance between the knockout hole assembly and the top of the box body. The purpose is to reduce the depth of the construction groove, avoid encountering steel bars during construction, increase the difficulty of construction, and make construction more convenient.

[0028] (3) This utility model reduces the distance between two knockout holes on the same side wall, and minimizes the groove width to the greatest extent while ensuring that the cup comb can be installed normally, thereby improving construction efficiency.

[0029] (4) The knock-out hole assembly of this utility model is set as a concentric hole with different diameters, which can be used for cup combs of different diameters, meet the construction needs of different working conditions, and make construction more convenient. Attached Figure Description
