Description

Technical Field

[0001] This utility model relates to the field of building electrical circuit protection technology, specifically to a building electrical circuit protection device. Background Technology

[0002] Electrical circuits are a technical term in electrical engineering. Any wire connecting electrical equipment and transmitting electrical energy can be called an electrical circuit, ranging from high-voltage transmission lines to low-voltage control lines. Wires refer to the conductors that transmit electrical energy. In construction sites, when connecting two electrical circuits, insulating tape is usually used to wrap and secure the connection. However, over time, the insulating tape may oxidize and peel off, or the connection may break due to tension. To prevent these problems and avoid leakage, building electrical circuit protection equipment is needed. However, existing protection equipment is inadequate in securing the connection between two electrical circuits. To address these issues, this application designs a building electrical circuit protection device. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A circuit protection device for building electrical systems includes a bottom shell 1 and a top shell 2, which are fixed together by bolts. Both the bottom shell 1 and the top shell 2 have a first groove 3, which close to form a complete cylindrical channel. Both the bottom shell 1 and the top shell 2 have a structural groove 4 located in the middle. An arc-shaped base 5 is fixed within the structural groove 4 on the bottom shell 1. Movable blocks 6 are provided on both sides of the arc-shaped base 5, and the movable blocks 6 are slidably connected to the structural groove 4. Multiple springs 7 are fixed to the outer ends of the movable blocks 6, and the other ends of the springs 7 are fixed to the inner wall of the structural groove 4. A locking block 8 is provided above the movable block 6, and a rubber fixing band 9 is fixed between two locking blocks 8. The locking blocks 8 and the movable blocks 6 are fixed together by bolts.

[0023] When using this equipment, first separate the bottom shell 1 from the top shell 2. Connect the two ends of the wiring using a traditional method and initially fix them with insulating tape. Separate the two locking blocks 8 from the moving blocks 6. Place the wiring connection on the arc-shaped base 5, with the two moving blocks 6 away from the arc-shaped base 5. The arc-shaped base 5 is also made of insulating rubber. Position the rubber fixing band 9 above the wiring connection. Align the locking blocks 8 with the moving blocks 6, with the moving blocks 6 being lower than the arc-shaped base 5. Insert the posts 18 on the moving blocks 6 into the locking blocks 8. Simultaneously, use bolts to fix the two locking blocks 8 to the moving blocks 6 respectively. The locking blocks 8 continuously move closer to the moving blocks 6 and fit snugly. The two wiring connections have a certain thickness. After the rubber fixing band 9 contacts the connection, both sides continuously move downwards along with the locking blocks 8 as they approach the moving blocks 6. The rubber fixing band 9 has a certain degree of flexibility and bends. As the rubber fixing band 9 bends, the bending action of the rubber fixing band 9 moves the two locking blocks 8... Approaching the arc-shaped base 5, the locking block 8 drives the moving block 6 to approach the arc-shaped base 5. At this time, the spring 7 is stretched, and the rubber fixing strip 9 is firmly attached to the connection of the line through the pulling force. This protects the insulating tape while squeezing and fixing the connection to prevent it from breaking. Finally, the bottom shell 1 and the top shell 2 are closed and fixed with bolts. The use of the reinforcement mechanism is such that when the top shell 2 and the bottom shell 1 are closed, the lines at both ends are located in the first grooves 3 at both ends. At this time, the adjusting threaded column 14 is rotated, and the locking block 13 threaded on the adjusting threaded column 14 moves down along the lifting slide 12 and approaches the rubber surface of the line to squeeze it, preventing the equipment from sliding along the line. The use of the rubber sealing ring 17 is such that before the lines at both ends are connected, the rubber sealing ring 17 is fitted on the outer wall of the line, and when the line is placed on the first groove 3, the rubber sealing ring 17 is placed on the waterproof groove 16. The size of the rubber sealing ring 17 is set to be slightly larger, and it is firmly attached to the waterproof groove 16 through the extensibility and deformation of the rubber.

[0024] In actual use, it was found that the moving block 6 would misalign and wobble when moving along the structural groove 4. To avoid the above problem, in this embodiment, two fixing blocks 10 are symmetrically fixed in the structural groove 4 located on the bottom shell 1. The fixing blocks 10 are located below the arc-shaped base 5. Multiple limiting rods 11 are fixed between the fixing blocks 10 and the corresponding inner wall of the structural groove 4. The limiting rods 11 pass through the moving block 6 and are slidably connected to it. Part of the spring 7 is sleeved on the limiting rod 11.

[0025] In actual use, it was found that even after the device is fixed on the line, it may still slide along the line, causing the connection to be exposed. In order to further strengthen the fixation of the device, in this embodiment, the top shell 2 is provided with a reinforcement mechanism. The reinforcement mechanism includes a lifting slide groove 12. The top shell 2 is provided with a lifting slide groove 12 at both ends. A locking block 13 is slidably connected in the lifting slide groove 12. An adjusting threaded column 14 is rotatably connected to the top shell 2. The bottom end of the adjusting threaded column 14 is located in the lifting slide groove 12 and is threadedly connected to the locking block 13. The bottom end of the locking block 13 is set to be arc-shaped and adapted to the first groove 3. An extension groove 15 adapted to the locking block 13 is provided on the first groove 3 on the bottom shell 1.

[0026] In actual use, it was found that water can easily seep into the connection point along the line at the first groove 3, causing leakage. In order to alleviate the above problem, in this embodiment, a plurality of waterproof slots 16 are provided on the first groove 3. The waterproof slots 16 are located inside the reinforcement mechanism. Two opposite waterproof slots 16 can close to form a complete circle. A rubber sealing ring 17 is movably provided on the waterproof slots 16.

[0027] In actual use, it was found that when the locking block 8 and the moving block 6 are not in a completely tight fit after being connected by bolts, the locking block 8 will shake. In order to avoid the above problem, in this embodiment, two columns 18 are symmetrically fixed at the top of the moving block 6. The columns 18 can pass through the locking block 8 and slide to connect with it.

[0028] In actual use, it was found that in order to increase the contact friction between the card block 13 and the line, in this embodiment, the bottom end of the card block 13 is provided with anti-slip stripes.
