Technical Field

[0001] The invention relates to the technical field of building decoration, and in particular to a wire threading box with a portable connecting wire pipe having a threaded structure. Background Art

[0002] Plastic blind boxes (wire boxes) are widely used in the field of construction engineering. When conventional blind boxes are connected to wire pipes, cup comb products are required to assemble the wire pipes and the blind boxes to ensure a tight connection between the wire pipes and the blind boxes.

[0003] In the prior art, plastic adhesive boxes are usually connected by punching holes and then cup combs to fix the wire tubes. However, during construction, workers often forget to use the cup combs and directly connect the wire tubes. Directly connecting the wire tubes to the plastic adhesive box will cause the wire tubes to loosen easily, and the wall mortar will penetrate and corrode the lines; the wire tubes will not be able to protect the lines. Summary of the Invention

[0004] The present invention provides a wire threading box with a portable threaded structure for connecting wire pipes, which can solve the problems in the prior art of punching-type plastic glue dark boxes, that is, when the wire pipes are directly connected to the plastic glue dark box, the wire pipes are easy to loosen, the wall mortar penetrates and corrodes the lines, and the wire pipes cannot protect the lines.

[0005] To achieve the above objectives, the technical solutions adopted by the present invention are as follows:

[0006] A wire threading box with a portable threaded structure for connecting wire pipes, comprising a wire box body and a sealing piece. The side walls of the wire box body are each provided with at least one side hollow connecting portion, the side hollow connecting portion being used to directly connect to the wire pipe or adapt to a cup comb, and the detachable sealing cover of the sealing piece is provided on the side hollow connecting portion.

[0007] As a further solution of the present invention: the side hollow connecting portion is a side hollow tube, the inner wall of the side hollow tube is evenly provided with internal threads, and the outer wall of the side hollow tube is evenly provided with external threads.

[0008] As a further solution of the present invention: the sealing piece is a hollow threaded plug, one end of the hollow threaded plug is sealed by a cover plate, the inner wall of the hollow threaded plug is evenly provided with internal threads matching the external threads of the side hollow tube, and the hollow threaded plug is used to seal the unused side hollow tube.

[0009] As a further solution of the present invention: the diameter of the cover plate is larger than the diameter of the hollow threaded plug, and a plurality of grooves are evenly formed on the edge of the cover plate.

[0010] As a further solution of the present invention: an annular sealing groove is provided on one end of the inner wall of the side hollow tube close to the wire box body, and an elastic sealing ring is embedded in the annular sealing groove.

[0011] As a further solution of the present invention: the depth of the side hollow tube is 1.5-2 times the wall thickness of the wire box body.

[0012] As a further solution of the present invention: the wire box body and the side hollow tube are integrally injection-molded.

[0013] As a further solution of the present invention: it also includes an adapter cup comb, one end of which is threadedly connected to the internal thread of the inner wall of the side hollow tube, and the other end is provided with a wire pipe buckle.

[0016] Beneficial effects of the present invention:

[0017] (1) The present invention optimizes the original punching positions of the side walls around the main body of the line box to set a side hollow connection part. The side hollow connection part is compatible with an adapter cup comb or a wire pipe, and is used to directly connect the wire pipe or the adapter cup comb; it supports the wire pipe with an external thread (such as a galvanized steel pipe) to be directly screwed into the side hollow connection part (engagement length ≥10mm), with a pull-out force ≥60N, which is suitable for surface installation scenarios. It also supports screwing the adapter cup comb into the side hollow connection part, and then inserting the φ20mm non-threaded PVC wire pipe to be installed into the buckle end of the adapter cup comb. The non-threaded wire pipe (such as a PVC pipe) is clamped by the buckle of the adapter cup comb, which is suitable for φ16-25mm specifications. The clamping force can be adjusted in the range of 10-30N, which is suitable for concealed installation requirements;

[0018] (2) The present invention provides a sealing member on the side hollow connection part on the side wall of the box body. The sealing member is a hollow threaded plug. The side hollow connection part is a side hollow tube. The hollow threaded plug is used to seal the unused side hollow tube. When the side hollow tube is not in use, it can be sealed by the threaded plug to prevent foreign matter from invading or mortar from penetrating into the side hollow tube, making the side hollow tube unusable.

[0019] (3) The present invention eliminates the secondary processing steps such as punching and tapping required for traditional wire boxes by integrally injection molding the wire box body and the side hollow tube. The traditional wire box production requires five steps: injection molding → punching → tapping → cleaning → quality inspection, while the present invention only requires two steps: injection molding → quality inspection, shortening the production cycle by 40%, reducing the investment in stamping equipment (such as punching machines and molds), and reducing the production cost per piece by 30%;

[0020] (4) The present invention provides a bottom mounting plate on the bottom periphery of the wiring box body, so that the wiring box body can be quickly and firmly installed in the corresponding position, and provides a top mounting plate on the top periphery of the wiring box body to facilitate the rapid installation of the panel.

[0030] Example 1

[0031] See also Figure 1-3 As shown, the first embodiment of the present invention provides a wire threading box with a portable connection wire tube with a threaded structure, including a wire box body 1 and a blocking member.

[0032] The main body of the box 1 is a rectangular cavity. A side hollow connection portion is optimized at the original punching position of the side walls of the box main body 1. The side hollow connection portion is compatible with an adapter cup comb or wire tube and is used to directly connect to the wire tube or adapter cup comb. The removable sealing cover of the plugging piece is provided on the side hollow connection portion. The box main body 1 provides an enclosed space for wires and cables to avoid mechanical damage and environmental corrosion. The box main body 1 is made of flame-retardant polycarbonate (PC) material, which meets the UL94 V-0 flame retardant standard and has an oxygen index of ≥28%. It can be used for a long time in an environment of -40°C to 120°C. When a pressure of 500N is applied, the deformation of the box main body 1 is less than 0.5mm.

[0033] See also Figure 2As shown, in this embodiment, the side hollow connection portion is a side hollow tube 2, the inner wall of the side hollow tube 2 is evenly provided with internal threads 201, and the outer wall of the side hollow tube 2 is evenly provided with external threads 202. The internal threads 201 and the external threads 202 are standard metric threads M20×2 (outer diameter 20mm, pitch 2mm), with a depth of 15mm. The side hollow tube 2 is compatible with the adapter cup comb or directly connected to the threaded wire pipe. The side hollow tube 2 is directly connected to the wire pipe with external threads, such as PVC threaded pipe, through the internal threads 201 to achieve quick installation. The side hollow tube 2 can also cooperate with the threaded end of the adapter cup comb through the internal threads 201 to provide a transition connection and adapt to non-threaded wire pipes. After the adapter cup comb is connected, the wire pipe pull-out force is ≥65N. The depth of the side hollow tube 2 is 1.5-2 times the wall thickness of the junction box body 1. An annular sealing groove is provided on the inner wall of the side hollow tube 2 near one end of the junction box body 1. An elastic sealing ring 203 is embedded in the annular sealing groove. The elastic sealing ring 203 can be silicone rubber with a Shore hardness of 50A and a compression rate of 25%. It can withstand a water pressure of 0.1MPa without leakage. Preferably, a micro temperature and humidity sensor can also be embedded in the inner wall of the side hollow tube 2. The data is transmitted to the mobile phone APP via Bluetooth to monitor the line status in real time. The junction box body 1 and the side hollow tube 2 are integrally injection molded using a precision mold. The injection pressure is 80-100MPa and the holding time is 30s, ensuring that the internal thread 201 and the external thread 202 are formed in one step without burrs or deformation. The punching process of the traditional junction box is eliminated, reducing production costs by 30%.

[0034] See also Figure 3As shown, in this embodiment, the sealing member is a hollow threaded plug 3. The threaded plug is a hollow cylinder. The inner wall of the hollow cylindrical threaded plug is uniformly provided with internal threads 302 that match the external threads 202 of the side hollow tube 2. One end of the hollow threaded plug 3 is sealed by a cover plate 301. The diameter of the cover plate 301 is larger than the diameter of the hollow threaded plug 3. The edge of the cover plate 301 is uniformly provided with a number of grooves 303. The grooves 303 facilitate tightening or loosening the threaded plug. The hollow threaded plug 3 is used to seal unused side hollow tubes 2. A rubber sealing ring can be embedded in the end of the threaded plug near the cover plate 301 to improve the sealing of the connection between the threaded plug and the corresponding side hollow tube 2. The threaded plug is made of the same material as the junction box body 1, with a flame retardant rating of UL94 V-0 and an oxygen index of ≥28%. It can be used for long-term use in environments of -40°C to 120°C. Furthermore, the threaded section of the internal thread 302 is sprayed with a nano-silicon coating with a thickness of 0.1mm, and the friction coefficient is reduced to 0.12, and the disassembly torque is ≤0.5N·m. When the side hollow tube 2 is not in use, it can be sealed with a threaded plug to prevent foreign matter from invading or mortar from penetrating into the side hollow tube 2, which would render the side hollow tube 2 unusable. The threaded plug is screwed to the side hollow tube 2, with an axial pull-out force ≥50N and a torque of 1.2N·m applied. The internal thread 302 of the threaded plug has no slipping or deformation. There is no leakage under a water pressure of 0.1MPa for 1 hour, and the sealing performance maintains an IP54 level at a vibration frequency of 10Hz.

[0035] It should be noted that in the embodiment of the present application, one end of the adapter cup comb is threadedly connected to the internal thread 201 on the inner wall of the side hollow tube 2, and the other end is provided with a wire pipe clip. The adapter cup comb engages with the internal thread 201 on the inner wall of the side hollow tube 2 through one end to establish a stable mechanical connection, and the clip structure at the other end clamps the wire pipe to prevent it from falling off. The clip supports the rapid switching of wire pipes of different specifications and is compatible with φ16mm, φ20mm, and φ25mm standard PVC wire pipes. The adapter cup comb is made of the same material as the threaded plug and the wire box body 1, with a flame retardant rating of UL94 V-0 and an oxygen index of ≥28%.

[0036] Example 2

[0037] See also Figure 4 As shown, the second embodiment of the present invention provides a wire threading box with a portable threaded structure for connecting wire pipes, including a wire box body 1 and a plugging member. The wire box body 1 is a rectangular cavity. The original punching positions of the side walls of the wire box body 1 are optimized to provide a side hollow connection portion. The side hollow connection portion is compatible with an adapter cup comb or wire pipe and is used to directly connect to the wire pipe or adapter cup comb. The plugging member has a detachable sealing cover provided on the plugging member.

[0038] In this embodiment, based on the first embodiment, a bottom mounting plate 101 is provided on the bottom periphery of the wiring box body 1, and a top mounting plate 102 is provided on the top periphery of the wiring box body 1. Bottom mounting plate 101 surrounds the bottom periphery of the wiring box body 1 and has a mounting hole at each of its four corners. The mounting holes and bottom mounting plate 101 allow the wiring box body 1 to be securely mounted in the desired location. Top mounting plate 102, located on the top of the wiring box body 1, facilitates panel installation.

[0039] Furthermore, a number of reinforcing ribs 103 are evenly arranged between the bottom mounting plate 101 and the top mounting plate 102. The upper end of the reinforcing rib 103 is fixedly connected to the bottom of the top mounting plate 102, and the lower end of the reinforcing rib 103 is fixedly connected to the top of the bottom mounting plate 101. The reinforcing rib 103 is tightly attached to the side of the wiring box body 1. The several reinforcing ribs 103 can strengthen the strength of the wiring box body 1 and withstand greater pressure.

[0040] Assembly and construction process

[0041] 1. Concealed installation (residential scene)

[0042] 1.1. Wall grooving: The groove depth is 60mm and the width is 110mm. Clean the dust after grooving and spray the interface agent (such as epoxy resin) to enhance the bonding strength. The main body of the junction box 1 is embedded in the wall groove, and the edge is ≤2mm away from the wall.

[0043] 1.2. Fix the junction box body 1: Insert M6 expansion bolts into the mounting holes of the bottom mounting plate 101 with a torque of 2.5 N·m. Use a laser level to calibrate the position of the junction box body 1 with a horizontal error of ≤1 mm / m.

[0044] 1.3. PVC Conduit Connection: Select the desired hollow tube 2 and remove the corresponding threaded plug. Then, screw the adapter comb onto the hollow tube 2 with the removed plug, using a torque of 0.6 N·m. Ensure that the threads of the adapter comb fully engage with the internal threads 201 of the desired hollow tube 2. Next, insert the φ20 mm PVC conduit to be installed into the clip end of the adapter comb. A click indicates that the connection is locked. Thread the unused hollow tube 2 into the threaded plug. Tighten the rubber seal inside the plug and apply waterproof adhesive, such as silicone adhesive. To replace the PVC conduit, loosen the adapter comb and press the clip release button. After removing the old conduit, install the new conduit within 5 seconds, and the clip will automatically lock.

[0045] 1.4. Install the panel: After all the wire tubes are installed, seal and fix the cover on the top mounting plate 102 of the wiring box body 1 to close the panel, thereby forming a closed space inside the wiring box body 1, providing a closed space for wires and cables to avoid mechanical damage and environmental erosion.

[0046] In old building renovations, the present invention's wire-through box replaces traditional plastic-lined blind boxes. No additional punching is required during construction; the wire conduits are connected directly through the side hollow tube 2, saving 30% of labor time. Threaded plugs seal unnecessary holes, preventing mortar infiltration and extending the life of the wiring to over 15 years.

[0047] 2. Surface-mounted construction (industrial scene)

[0048] 2.1. Installation of the junction box body 1: Use stainless steel self-tapping screws (ST4.2×25mm) to pass through the mounting holes of the mounting plate 101 at the bottom of the junction box body 1 to fix the junction box body 1 to the steel frame. A rubber gasket (2mm thick) can be installed at the bottom of the junction box body 1 to reduce vibration transmission.

[0049] 2.2. Direct connection of threaded conduit: Select the target side hollow tube 2, unscrew the corresponding threaded plug, and then screw the threaded conduit to be installed (such as a galvanized steel pipe) directly into the target side hollow tube 2. The engagement length should be ≥10mm. Ensure that the thread of the threaded conduit is fully engaged with the internal thread 201 of the target side hollow tube 2 without any cross-threading; wrap the conduit and the target side hollow tube 2 with raw tape to enhance the sealing.

[0050] 2.3. Install the panel: After all the wire tubes are installed, seal and fix the cover on the top mounting plate 102 of the wiring box body 1 to close the panel, thereby forming a closed space inside the wiring box body 1, providing a closed space for wires and cables to avoid mechanical damage and environmental erosion.

[0051] Frequent line changes are required in factories, and the present invention supports quick disassembly and assembly of wire tubes. The adaptor cup comb is threadedly connected to the side hollow tube 2. When replacing the wire tube, only the adaptor cup comb needs to be loosened, reducing the operation time by 50%.

[0052] In summary, this invention comprehensively optimizes the production efficiency, connection reliability, protection performance, and structural strength of traditional wire-through boxes through its integrated molding process, multi-mode connection design, dynamic sealing mechanism, and use of high-strength materials. Tested data shows a 30% reduction in production costs, a 40% increase in construction efficiency, an IP67 protection rating, and an extended service life of over 25 years. It can be widely used in residential, industrial, and outdoor applications, providing an efficient, durable, and intelligent solution for building electrical engineering.

[0053] The above detailed description of the preferred embodiments of the present invention should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent of the present invention.
