Description

Technical Field

[0001] This utility model relates to an electrical wiring pre-embedded installation box, belonging to the technical field of electrical wiring components. Background Technology

[0002] Electrical wiring is one of the most important facilities in the electrical field. It transmits electricity, delivering power to various users and providing them with energy. Simultaneously, it transmits electrical signals, playing an indispensable role in information transmission in modern society. Currently, many electrical lines are laid underground, requiring the use of pre-embedded installation boxes during the installation process.

[0003] While widely used pre-embedded mounting boxes can accomplish the installation and connection of wiring, their internal structure is simple, consisting only of some wiring harness restraints. The long installation area lacks any partitioning structures. In the event of an accidental short circuit and fire, the flames can rapidly propagate along the mounting box, endangering the entire length of wiring within. This not only results in resource waste but also increases the risk to the area, making the overall structural application ineffective. Therefore, there is an urgent need for a safe and reliable pre-embedded mounting box for electrical wiring to address these problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a safe electrical wiring pre-embedded installation box. This pre-embedded installation box can effectively block the fire source, prevent the flame from spreading rapidly, and control and extinguish the flame, thus providing good protection. It can improve the safety of the pre-embedded installation box and prevent electrical wiring fires and losses.

[0005] The technical solution to the above technical problem is:

[0006] An electrical wiring pre-embedded installation box with safe operation includes a pre-embedded box, a top cover, and wiring dividers. The pre-embedded box is a rectangular box body. Multiple wire holes are evenly distributed on the lower part of the two end faces along the length of the pre-embedded box. The multiple wire holes are close to the bottom surface of the pre-embedded box. An openable top cover is installed at the top of the pre-embedded box. The wiring dividers are square plates. Multiple wiring dividers are vertically fixed to the lower surface of the top cover in sequence along the length of the top cover. The surface of the wiring dividers is perpendicular to the length of the pre-embedded box. The surface of the wiring dividers matches the inner cavity cross section of the pre-embedded box. The two side edges of the wiring dividers are in sliding fit with the two side inner walls of the pre-embedded box. The lower end of the wiring dividers has multiple wire harness slots. The multiple wire harness slots are arranged in sequence along the lower edge of the wiring dividers. The multiple wire harness slots are respectively opposite to the multiple wire holes at both ends of the pre-embedded box.

[0007] The aforementioned safe electrical wiring pre-embedded installation box comprises a wiring partition plate consisting of a frame, a flip plate, and a fire extinguishing powder storage bag. The frame is a rectangular frame, and the flip plate is a rectangular plate. The surface of the flip plate matches the inner circumference of the frame, and the flip plate is embedded in the inner cavity of the frame. A rotating shaft is fixed on each of the lower two sides of the flip plate. A shaft hole is provided on the inner wall of each side of the frame to match the rotating shaft of the flip plate. The rotating shaft and the shaft hole are in a rotatable fit. A fire extinguishing powder storage bag is fixed on the outer surface of the flip plate.

[0008] The aforementioned safe electrical wiring pre-embedded installation box has a thermal expansion block sleeve, thermal expansion block, rack, gear, and baffle installed on one side of the upper part of the frame of the wiring partition plate. The thermal expansion block sleeve is horizontally fixed to the side of the frame above the flip plate. The thermal expansion block is embedded in the thermal expansion block sleeve and the thermal expansion block and thermal expansion block sleeve are in sliding fit. The front end of the thermal expansion block is connected to the rear end of the rack. There is a gear on the side of the frame at the front end of the rack. There is a gear shaft hole on the side of the frame. The gear shaft and the gear shaft hole of the frame are in rotational fit. The rack meshes with the upper part of the gear. The lower part of the gear is fixedly connected to the upper end of the baffle. The lower part of the baffle extends out of the inner edge of the frame and is stuck on the outer side of the flip plate.

[0009] The beneficial effects of this utility model are:

[0010] This utility model uses multiple circuit dividers to divide the inner cavity of the pre-embedded box into multiple isolated chambers. When a short circuit occurs in the wiring harness at the bottom of the pre-embedded box, each circuit divider can effectively block the fire source within the divided area, making it difficult for the flame to spread quickly and providing good protection. At the same time, when a short circuit occurs in the wiring harness, the thermal expansion block above the circuit divider corresponding to the ignition point expands due to heat and moves along the thermal expansion block sleeve. The thermal expansion block drives the rack to move laterally, and the laterally moving rack drives the gear to rotate. The baffle rotates synchronously with the gear. When the baffle rotates to the top of the flip plate and disengages from the flip plate, the flip plate can automatically flip to a horizontal state. The flame will directly burn the fire extinguishing powder storage bag. After the fire extinguishing powder storage bag is burned through, a large amount of fire extinguishing powder inside can fall directly to the ignition point of the wiring harness to extinguish the fire.

[0011] This utility model has a simple structure and is easy to use. It can effectively block the fire source, making it difficult for the flame to spread quickly. It can also control and extinguish the flame, providing good protection and improving the safety of the pre-embedded installation box. It effectively avoids fires and losses caused by electrical circuits. Attached Figure Description

[0017] This utility model consists of a pre-embedded box 1, a top cover 2, a wire hole 3, and a circuit partition plate 4.

[0018] Figure 1 As shown, the embedded box 1 is a rectangular box. Multiple wire holes 3 are evenly distributed on the lower part of both ends of the embedded box 1 along its length. The multiple wire holes 3 are close to the upper surface of the bottom surface of the embedded box 1. Multiple wire bundles enter the cavity of the embedded box 1 from different wire holes 3, and the wire bundles are laid flat along the bottom surface of the embedded box 1.

[0019] Figure 1 The display shows that the upper end of the embedded box 1 is equipped with an openable top cover 2. The wiring divider 4 is a square plate, and multiple wiring dividers 4 are vertically fixed to the lower surface of the top cover 1 along the length of the top cover 2. The surface of the wiring divider 4 is perpendicular to the length of the embedded box 1. The surface of the wiring divider 4 matches the cross-section of the inner cavity of the embedded box 1, and the two side edges of the wiring divider 4 are in sliding fit with the inner walls of the two sides of the embedded box 1. The lower end of the wiring divider 4 has multiple wire harness slots 5, which are arranged sequentially along the lower edge of the wiring divider 4. These slots correspond to multiple wire holes 3 at both ends of the embedded box 1. Multiple wire harnesses that enter the embedded box 1 through the wire holes 3 and are laid on the bottom surface of the embedded box 1 are embedded in the multiple wire harness slots 5.

[0020] Figure 2 , 3 The circuit divider 4 consists of a frame 6, a flip plate 7, and a fire extinguishing powder storage bag 10. The frame 6 is a rectangular frame, and the flip plate 7 is a rectangular plate. The surface of the flip plate 7 matches the inner circumference of the frame 6, and the flip plate 7 is embedded in the inner cavity of the frame 6. Rotating shafts 8 are fixed on both sides of the lower part of the flip plate 7. There are shaft holes 9 on the inner walls of both sides of the frame 6, which match the rotating shafts 8 of the flip plate 7. The rotating shafts 8 and the shaft holes 9 are in a rotating fit, and the flip plate 7 can be rotated to a horizontal position through the rotating shafts 8.

[0021] Figure 2 , 3The display shows that a fire extinguishing powder storage bag 10 is fixed on the outer side of the flip plate 7. When the flip plate 7 is rotated to the horizontal position, the fire extinguishing powder storage bag 10 can be used for fire extinguishing.

[0022] Figure 2 , 3 As shown in Figure 4, a thermal expansion block sleeve 11, a thermal expansion block 12, a rack 13, a gear 14, and a baffle 15 are installed on one side of the upper part of the frame 6 of the circuit separator plate 4. The thermal expansion block sleeve 11 is horizontally fixed to the side of the frame 6 above the flip plate 7. The thermal expansion block 12 is embedded in the thermal expansion block sleeve 11 and can slide along the thermal expansion block sleeve 12. The front end of the thermal expansion block 12 is connected to the rear end of the rack 13. There is a gear 14 on the side of the frame 6 at the front end of the rack 13. There is a gear shaft hole on the side of the frame 6. The gear shaft and the gear shaft hole of the frame 6 are rotatably engaged. The rack 13 and the gear 14 mesh at the upper part. When the rack 13 moves, it can drive the gear 14 to rotate around the gear shaft. The lower part of the gear 14 is fixedly connected to the upper end of the baffle 15. The lower part of the baffle 15 extends out of the inner edge of the upper part of the plate frame 6 and is stuck on the outer side of the plate surface of the flip plate 7. When the gear 14 rotates, it can drive the baffle 15 to rotate. The baffle 15 can either block the outer side of the flip plate 7 or rotate to the top of the flip plate 7 and disengage from the flip plate 7.

[0023] The usage process of this utility model is as follows:

[0024] In actual pre-installation of electrical wiring harnesses, the electrical wires are directly inserted into the pre-embedded box 1 through the wire hole 3. The top cover 2 is lifted, and the top cover 2 lifts the wiring divider 4. The operator neatly lays the wiring harnesses inserted into the pre-embedded box 1 in a straight line on the bottom surface of the inner cavity of the pre-embedded box 1. Then the top cover 2 is pressed down, and the wiring divider 4 is pressed down simultaneously, placing each wiring harness in the wiring harness slot 5 at the lower end of the wiring divider 4, thus completing the installation and positioning of the wiring harnesses. After installation, the wiring divider 4 divides the long pre-embedded box 1 into multiple different areas, and also separates the installed wiring harnesses into different areas.

[0025] When a short circuit occurs in the wiring harness at the bottom of the pre-embedded box 1, the various line partitions 4 can effectively block the fire source within the partitioned area, making it difficult for the flame to spread quickly and providing good protection.

[0026] Meanwhile, when a short circuit fire occurs in the wiring harness, the thermal expansion block 12 above the wiring divider 4 corresponding to the ignition point expands due to heat. The thermal expansion block 12 slides along the thermal expansion block sleeve 11 and moves outward within the thermal expansion sleeve 11. When the thermal expansion block 12 moves, it drives the rack 13 to move laterally. The laterally moving rack 13 can drive the gear 14 meshing with it to rotate. The baffle 15 rotates synchronously with the gear 14. The baffle 15 rotates to the top of the flip plate 7 and disengages from the flip plate 7. The flip plate 7 can automatically flip around the rotating shaft 8 to a horizontal state. The flame will directly burn the fire extinguishing powder storage bag 10 on the surface of the flip plate 7. After the fire extinguishing powder storage bag 10 is burned through, a large amount of fire extinguishing powder inside can fall directly to the ignition point of the wiring harness to extinguish the fire.
