Description

Technical Field

[0001] This invention relates to the field of switch and socket junction box technology, specifically to a switch and socket panel junction box fixing device. Background Technology

[0002] In building construction and various decoration projects, junction boxes are essential electrical tools. There is a difference between junction boxes and receptacles. Receptacles are mainly used for installing wiring panels for various switches, sockets, and other electrical appliances. To maintain a clean and aesthetically pleasing building surface, junction boxes generally need to be pre-installed. They simultaneously connect electrical wires, provide a transition for various electrical circuits, and protect the wiring safety. Commonly used junction boxes include type 86, type 120, octagonal junction boxes, and other special-purpose boxes. Some electrical concealed enclosures can also be called junction boxes. Junction boxes made of different materials should not be mixed. For example, metal junction boxes have better grounding, fire resistance, and hardness. Materials like PVC have better insulation properties. During use, avoid damaging the box's structure, as this can easily lead to deformation during pre-installation, negatively impacting panel installation. Also, during conduit and wire installation, care must be taken to prevent damage to wires from the pre-drilled holes in the junction box.

[0003] During the repair of lighting switches and sockets in various areas, it is frequently found that the bolt bases on the recessed boxes embedded in the walls of sockets or switches are worn, detached, or damaged. This makes it impossible to secure the switch panel during repairs, leading to potential safety hazards. Previously, repairs required chiseling out the recessed box from the wall, installing a new box, and then gluing it to the wall – a time-consuming and inefficient process. Given the current situation and the large number of boxes requiring repair, chiseling out and reinstalling each box would incur significant labor and spare parts costs. Therefore, we have designed and manufactured a special fixing device that eliminates the need to chisel out the old boxes, simplifying installation and improving efficiency while reducing maintenance costs.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-6A switch and socket panel recessed box fixing device includes a device box 1. The device box 1 is made of ABS plastic, which is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S). The relative contents of the three monomers can be varied to produce various resins. ABS plastic combines the common properties of the three components: A provides chemical corrosion resistance, heat resistance, and a certain surface hardness; B provides high elasticity and toughness; and S provides the processing and molding characteristics of thermoplastics and improves electrical properties. Therefore, ABS plastic is a "tough, hard, and rigid" material that is readily available, has good comprehensive performance, is inexpensive, and has a wide range of applications. ABS plastic has been widely used in machinery, electrical, textile, automotive, aircraft, shipbuilding, and other manufacturing industries, as well as in the chemical industry. ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S). It combines the properties of the three components: acrylonitrile has high hardness and strength, heat resistance, and corrosion resistance; butadiene has impact resistance and toughness; and styrene has high surface gloss, easy coloring, and easy processing. The properties of the three components mentioned above make ABS plastic a thermoplastic with excellent comprehensive performance, characterized by its strength, toughness, and high rigidity. Adjusting the proportions of the three components changes its properties to meet various application requirements, such as high-strength ABS, heat-resistant ABS, and high-gloss ABS. ABS plastic has good processability and can be molded using injection molding, extrusion, and thermoforming methods. It can be machined by sawing, drilling, filing, and grinding, and can be bonded with organic solvents such as chloroform. It can also undergo surface treatments such as coating and electroplating. ABS plastic is also an ideal substitute for wood and a building material. ABS plastic has high strength, is lightweight, has high surface hardness, is very smooth, easy to clean, dimensionally stable, and has good creep resistance, making it suitable for electroplating. Its application areas continue to expand. ABS plastic is widely used in industry. ABS injection molded products are often used to make shells, boxes, parts, toys, etc. Extruded products are mostly sheets, rods, and tubes, which can be hot-pressed, composite processed, and molded. One end of the equipment box 1 is connected to a threaded rod drive assembly 2, and the other end of the equipment box 1 is connected to a screw sleeve drive assembly 3. The threaded rod drive assembly 2 is rotatably connected to a fixing bolt 4. The threaded rod drive assembly 2 is connected to a connecting rod 5 through the fixing bolt 4. The connecting rod 5 is connected to a retainer 6, and the retainer is connected to a threaded rod assembly 7. The equipment box 1 has a threaded hole inside, and a bolt B8 passes through the threaded hole. The equipment box 1 is connected to a retainer 9 through the threaded bolt B8, and a bolt drive assembly 10 is inserted inside the retainer 9.

[0022] The threaded rod transmission assembly 2 is connected to the equipment housing 1. Driven by the motor A204, it rotates the transmission threaded column 203 connected to the motor A204. The transmission threaded column 203 is internally connected to the bearing A202, which is connected to the equipment base A201. The rotation of the transmission threaded column 203 touches the threaded rods A701 and B703, causing them to rotate and move upward or downward, thus achieving the adjustment function and greatly improving the working efficiency of the equipment.

[0023] The screw sleeve drive assembly 3 is connected to the equipment housing 1 and driven by a motor B304. The motor B304 is connected to a rubber shaft 303, which is connected to a bearing B302. The bearing B302 is connected to the equipment base B301, thereby causing the rubber shaft 303 to rotate. The rubber shaft 303 has high friction, and by contacting the screw sleeve 702, the screw sleeve 702 rotates, allowing the screw sleeve 702 to move up and down to adjust its position. This greatly facilitates the adjustment of the screw sleeve 702's position and helps improve the overall working efficiency of the equipment. The rubber shaft 303 is made of nitrile rubber polymer, which is a copolymer of acrylonitrile and butadiene monomers. It is mainly produced by low-temperature emulsion polymerization and has excellent oil resistance, high wear resistance, good heat resistance, and strong adhesion. Its disadvantages include poor low-temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. Nitrile rubber is mainly used to manufacture oil-resistant rubber products. The higher the acrylonitrile content, the better the oil resistance, but the cold resistance decreases accordingly. It can be used for extended periods in air at 120°C or in oil at 150°C. Furthermore, it has good water resistance, airtightness, and excellent adhesion. It is widely used in the manufacture of various oil-resistant rubber products, various oil-resistant gaskets, washers, sleeves, flexible packaging, flexible hoses, printing and dyeing rollers, cable adhesive materials, etc., and has become an indispensable elastic material in the automotive, aerospace, petroleum, and photocopying industries. In a typical NBR structure, the trans group accounts for approximately 78%. Due to the presence of cyano groups in the NBR molecular chain structure, its oil resistance (such as resistance to mineral oils, liquid fuels, animal and vegetable oils, and solvents) is superior to that of natural rubber, chloroprene rubber, and styrene-butadiene rubber. Compared with other rubbers, NBR has a wider operating temperature range, with a long-term operating temperature of 120℃. At the same time, NBR has good low-temperature resistance, with a minimum glass transition temperature of -55℃. Due to its strong adhesion, high wear resistance, and strong friction, NBR provides a better fit for the rotation and adjustment of the screw sleeve 702. For shipyards with different maintenance environments, NBR polymer is particularly suitable.

[0024] The threaded rod assembly 7 is connected to the retaining seat 6. The retaining seat 6 can be rotated via the fixing bolt 4 and connecting rod 5. The threaded rod assembly 7 can be secured in the retaining seat 6 for easy installation. The threaded rod assembly 7 is then removed and screwed into the threaded sleeve 702 via threaded rods A701 and B703. It is then installed into the wall-mounted junction box. The threaded rod transmission assembly 2 and the threaded sleeve transmission assembly 3 are used to move the threaded sleeve 702 downwards or upwards, adjusting its position so that the threaded hole of the threaded sleeve 702 aligns with the original position of the junction box. The internal threaded bases are aligned, and bolts A704 are used to tighten the screw sleeve 702, thus serving as the base for random bolt connections within the concealed box. A motor C1002 provides the drive, aligning the screwdriver bit 1005 with the cross face of bolt A704, causing the bit 1005 to engage with bolt A704. Motor C1002 drives the bit 1005 to rotate, which in turn rotates the bolt A704, screwing it into the screw sleeve 702, further increasing the device's efficiency. The screwdriver bit 1005 typically refers to the screwdriver head mounted on a hand drill or hammer drill for tightening screws. Electric screwdriver bits are used to tighten or loosen screws. They are small power tools. Screwdriver bits can be classified into different types according to their head shape, such as slotted, Phillips, star, square, hexagonal, and Y-shaped heads. Slotted and Phillips are the most commonly used in daily life, while hexagonal heads are not used as often. Hex wrenches are more commonly used. Many screws on some machines have internal hexagonal holes, which allows for force to be applied from multiple angles.

[0025] The bolt drive assembly 10 is connected to the ferrule 9. The hand guard 1001 provides better protection for the user's hands. The bolt drive assembly 10 is driven by a motor C1002, which is connected to a connector 1003. An extension rod 1004 is connected to the connector 1003, and the extension rod 1004 can be fitted with different types of screwdriver bits 1005. The motor C1002 drives the connector 1003 to rotate, which in turn drives the extension rod 1004 to rotate, thereby driving the screwdriver bits 1005 to rotate. The screwdriver bits 1005 are compatible with bolt A704 and can engage, thus driving bolt A704 to rotate and allowing bolt A704 to be screwed into the screw sleeve 702 more quickly. The screwdriver bits 1005 are made of 45# steel, which is a high-quality carbon structural steel, corresponding to Japanese standard S45C, American standard 1045, and German standard C45. Compared to ordinary A3 steel, 45 steel has higher strength and resistance to deformation. It is a medium-carbon structural steel with good cold and hot working properties, good mechanical properties, and is widely used due to its low price and wide availability. Before tempering, a hardness greater than HRC55 (up to HRC62) is considered acceptable for 45 steel plates after quenching. After heat treatment and tempering, it can reach HRC42-46, thus ensuring both good mechanical properties and achieving the required surface hardness. It is used to manufacture small-section quenched and tempered parts with high load-bearing capacity, large normalized parts with low stress, and surface-quenched parts with low core strength requirements, such as pins, guide pillars, and dial indicators. Therefore, 1005 bit made from 45 steel has good mechanical properties and a low price, making it more suitable for various work conditions and reducing equipment manufacturing costs.

[0026] The internal components of the device housing 1 include a battery 11 and a driver 12. The driver in this device is an L298N driver, which is a dual-channel full-bridge motor driver chip that can accept high voltage and high current. The operating voltage can reach 46V, and the output current can reach up to 4A. It adopts a dynamic adjustment circuit operation mode and has a logic power input terminal. Through the built-in voltage regulator chip 78MO5, the internal logic circuit can operate at low voltage, and it can also output a logic voltage of 5V. All electrical components mentioned in this article are connected to the external L298N main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. However, the driver 12 and its servo motor are not limited to the L298N driver. They can be changed to the required driver and servo motor according to the needs of production. If a better driver and servo motor are available, they can be replaced as long as they can provide normal operation. The housing cover 14 is secured with bolt C13 to prevent the driver 12 and battery 11 from being exposed, thus providing better protection for them. The housing 1 is fitted with a grip sleeve 15 for more comfortable use. This grip sleeve 15 is made of soft PVC pipe, produced by extruding PVC resin with a large amount of plasticizer, stabilizer, and other additives. Soft PVC pipes possess excellent chemical stability, superior electrical insulation properties, and good flexibility and colorability. This type of pipe is commonly used to replace rubber hoses for transporting liquids and corrosive media, and is also used as cable conduit and wire insulation. The production process of soft PVC differs slightly from that of rigid PVC. Due to the presence of plasticizers in the soft PVC formulation, kneading and plasticizing is a crucial step in the production of soft PVC pipes. During the kneading process of soft PVC, the order of adding materials must be carefully considered to ensure the resin is fully swollen by the plasticizer and the kneaded material is evenly dispersed. When adding a certain amount of filler (such as CaCO3), the resin and plasticizer should be mixed first. If the resin and filler are mixed first, and then the plasticizer is added, the plasticizer will first penetrate into the filler particles because the filler's particle structure is generally more porous than the resin's. This prevents the resin from fully swelling. Kneading is typically done using a "Z" type kneader with jacket heating and a vapor pressure of approximately 0.24~0.39 MPa. Kneading should last 50~60 minutes. After kneading, the mixture should be frequently turned to prevent localized overheating and resin decomposition. The kneaded material is then granulated and extruded into pipes. The extrusion temperature can be slightly lower than that for PVC pipes. Its flexibility, excellent chemical stability, and superior electrical insulation make it more suitable for the working environment and applications of this equipment, and also improve the comfort of the equipment to a certain extent.

[0027] In use, the threaded rod assembly 7 is engaged via the clamp 6, allowing for the readily available backup threaded rods A701, 702, and B703. The threaded rod transmission assembly 2 enables the transmission threaded post 203 to contact threaded rods A701 and B703, driven by motor A204 to rotate them and adjust their positions. Reversing the mechanism allows the threaded rod transmission assembly 3 to contact the threaded sleeve 702, driven by motor B304 to rotate the rubber shaft 303, which then contacts the threaded sleeve 702. The screw sleeve 702 can be rotated to adjust its position so that the threaded hole is aligned with the corresponding position. The motor C1002 of the bolt transmission assembly 10 provides drive to rotate the connection port 1003. The connection port 1003 is connected to the extension rod 1004, and the extension rod 1004 is connected to the bit 1005, which can rotate the bit 1005. The bit 1005 is compatible with the bolt A704, and the bolt A704 can be rotated by the bit 1005, which can greatly improve the working efficiency of the device. The equipment hand guard 1001 and the grip sleeve 15 can provide a certain degree of protection for the equipment.

[0028] In summary, this switch and socket panel recessed box fixing device utilizes the installation of threaded rod assembly 7 into the recessed box within the wall. The positions of threaded rod A701 and threaded rod B703 are adjusted via threaded rod transmission assembly 2, and the position of threaded sleeve 702 is adjusted via threaded sleeve transmission assembly 3. This ensures that the threaded hole position on the threaded sleeve aligns with the original threaded base position within the recessed box. Furthermore, the height of bolt A704 is adjusted via bolt transmission assembly 10 to tighten the internal threaded sleeve, thus serving as the bolt connection base for the recessed box's inner panel. This eliminates the need to chisel out the old recessed box, making installation simple and convenient, improving work efficiency, and reducing maintenance costs.
