Description
Technical Field
[0001] This utility model relates to the technical field of arc fault protection devices, and in particular to a mounting base for a quick-connect arc fault protection device. Background Technology
[0002] In fields such as building electrical systems and industrial power distribution, arc fault protection devices are key equipment for preventing electrical fires. They can monitor arc faults in circuits in real time and quickly cut off the power supply to avoid fire risks. As the complexity of electrical systems increases, protection devices need to be inspected and replaced regularly. As the connection carrier between the protection device and the circuit, the structural design of the mounting base directly affects the convenience and efficiency of the replacement of the protection device. Currently, traditional mounting bases have the problem of cumbersome replacement procedures. Especially in densely installed scenarios such as power distribution rooms and distribution boxes, frequent disassembly operations not only prolong the power outage time, but also affect the normal operation of surrounding electrical equipment.
[0003] Existing arc fault protection device mounting bases mostly employ a bolt-fixed structure. Their mechanical structure primarily includes a metal base body, bolt holes at the four corners of the base, conductive terminals welded inside the base for connection to external circuits, and an insulating protective cover covering the base surface. The base is fixed to a mounting plate in a wall or distribution box using expansion bolts. The back of the protection device has slots that match the conductive terminals of the base. During installation, the slots of the protection device must be aligned with the conductive terminals and inserted. Then, a Phillips screwdriver is used to screw the fixing screws on both sides of the protection device into the pre-drilled threaded holes in the base, achieving both mechanical fixation and electrical connection. The mechanical tightening force of the bolts ensures a stable connection between the protection device and the base. Simultaneously, the tight contact between the conductive terminals and the slots of the protection device ensures circuit continuity, guaranteeing the real-time monitoring and protection function of the protection device against arc faults in the circuit.
[0004] However, existing bolt-fixed mounting bases have significant limitations. The replacement process for protection devices is cumbersome and time-consuming, affecting maintenance efficiency. When a protection device needs to be replaced, the operator must first disconnect the power, then use a screwdriver to remove the fixing screws on both sides of the protection device one by one. After removing the old device, the slot of the new device must be realigned with the conductive terminals of the base, and it must be slowly inserted to ensure good conductive contact. Then, the fixing screws are tightened again with a screwdriver. The entire process requires repeated tool operations. If the installation space is narrow, such as in a densely packed distribution box, the operation of the screwdriver is limited, and the replacement time will be further extended. If an emergency fault requires rapid replacement of the protection device, the excessively long replacement time will cause the circuit to be in an unprotected state for a long time, increasing the risk of electrical fire. In addition, frequent screw removal can also cause wear and stripping of the threaded holes, making it difficult to securely fix the subsequent protection device, resulting in loosening or even poor contact, affecting the normal operation of the protection device, and failing to meet the actual needs of rapid maintenance and safety assurance of electrical mechanisms. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a mounting base for a quick-connect arc fault protection device, which aims to improve the significant limitations of existing bolt-fixed mounting bases, the cumbersome and time-consuming process of replacing the protection device, and the impact on maintenance efficiency.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a mounting base for a quick-connect arc fault protection device, comprising a cabinet, a slide rail fixedly connected to the inner wall of the cabinet, a base body slidably connected to the outer wall of the slide rail, a protection mechanism provided on the outer wall of the base body, and a release component provided on the outer wall of the base body. The release assembly includes a first connecting block, the outer wall of which is fixedly connected to the outer wall of the base body. An inclined column is slidably connected to the inner wall of the first connecting block. A connecting column is fixedly connected to the outer wall of the inclined column. A spring is fixedly connected to the outer wall of the connecting column. One end of the spring is fixedly connected to the outer wall of the first connecting block. A sliding groove is provided on the inner wall of the first connecting block. A second rotating shaft is rotatably connected to the inner wall of the first connecting block. A first rotating shaft is fixedly connected to the outer wall of the second rotating shaft. An anti-detachment column is fixedly connected to the outer wall of the first rotating shaft. A fixing assembly is provided on the inner wall of the protection mechanism.
[0007] Furthermore, the fixing component includes a locking block, the outer wall of which is fixedly connected to the inner wall of the protection mechanism, the inner wall of which is provided with a locking post, the outer wall of which is fixedly connected to a connecting plate, and the outer wall of which is fixedly connected to a pressing block.
[0008] Furthermore, a slot is provided inside the slide rail, and a connecting block two is fixedly connected to the outer wall of the base body.
[0009] Furthermore, a pull block is slidably connected to the inner wall of the second connecting block, and an inclined block is fixedly connected to the outer wall of the pull block.
[0010] Furthermore, a slider is slidably connected to the outer wall of the inclined block, and the outer wall of the slider is slidably connected to the inner wall of the connecting block two.
[0011] Furthermore, the outer wall of the slider is slidably connected to the inner wall of the pull block and the inner wall of the slide rail.
[0012] Furthermore, the outer wall of the pressing block is slidably connected to the inner wall of the protection mechanism and the inner wall of the connecting block.
[0013] Furthermore, the outer wall of the connecting plate and the outer wall of the locking post are slidably connected to the inner wall of the protection mechanism.
[0014] This utility model has the following beneficial effects: 1. In this utility model, by pressing down on the connecting column, the inclined column slides and compresses the spring to store energy, and the linkage shaft one and the pressing block one slide, the locking column can be disengaged from the locking block, realizing the quick disassembly of the protective device. During installation, the protective device is placed on the base body, and pressing down on the pressing block one allows the locking column to be re-locked and fixed. The whole process does not require complicated tools, and the disassembly and assembly are completed by simple pressing and linkage action, which greatly shortens the replacement time and improves the equipment maintenance efficiency. At the same time, the spring energy storage and locking structure ensure the stability after installation and prevent the protective device from loosening and affecting the use.
[0015] 2. In this utility model, by pulling the pull block to drive the inclined block to slide, the slider is pushed out of the slot of the slide rail, which can release the fixation and adjust the position of the base body. After moving to the target position, the pull block is released, and the slider is re-engaged into the slot by the restoring force to complete the fixation. This design achieves quick unlocking and locking through the linkage of the pull block, inclined block and slider. The operation is simple and labor-saving, and it can flexibly adapt to the position requirements under different usage scenarios. Moreover, the engagement and cooperation between the slider and the slot ensures the stability of the base body after adjustment and improves the overall flexibility of the device.

[0018] 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.
[0019] Reference Figures 1-3 This utility model provides an embodiment of a quick-connect arc fault protection device mounting base, comprising a cabinet 1, which provides a mounting carrier for the entire mounting base. A slide rail 2 is fixed to the inner wall of the cabinet 1, providing a foundation for the sliding and fixing of the base body 16. The slide rail 2 is fixedly connected to the inner wall of the cabinet 1, providing a sliding track for the base body 16. The base body 16 can be adjusted along the slide rail 2 to adapt to different installation requirements. Simultaneously, the internal slot 17 cooperates with the slider 19 to fix the position of the base body 16. 2. The outer wall is slidably connected to the base body 16. The base body 16 is used to connect the protection mechanism 3 and the slide rail 2. The outer wall is equipped with a release component and a connecting block 21 to provide a fixed platform for the protection mechanism 3. At the same time, it can move along the slide rail 2 to realize the position adjustment of the protection mechanism 3. It is the core component connecting the protection device and the cabinet 1. The outer wall of the base body 16 is provided with the protection mechanism 3. The protection mechanism 3 is used to realize the arc fault protection function. It is installed in the cabinet 1 through the base body 16 and can be quickly disassembled or installed. The outer wall of the base body 16 is provided with a release component. The release assembly includes a connecting block 4, which is used to install the core component of the release assembly. Its inner wall provides sliding and rotational space for the inclined column 7, the rotating shaft 8, and the rotating shaft 9. The outer wall of the connecting block 4 is fixedly connected to the outer wall of the base body 16. The inclined column 7 is slidably connected to the inner wall of the connecting block 4. The inclined column 7 cooperates with the connecting column 6 and the rotating shaft 8 to perform inclined plane transmission. When the inclined column 7 slides with the connecting column 6, it pushes the rotating shaft 8 to rotate around the rotating shaft 9 through the inclined plane, converting the linear motion of the connecting column 6 into the rotational motion of the rotating shaft 8. The sliding of the pressing block 11 provides power to achieve the unlocking action. A connecting post 6 is fixedly connected to the outer wall of the inclined post 7. The connecting post 6 is used to trigger the unlocking action of the release component. When the operator presses the connecting post 6, it causes the inclined post 7 to slide and compress the spring 5, which is the point of force application for the unlocking operation. After release, it resets under the action of the spring 5, causing the inclined post 7 to return to its initial position. The connecting post 6 is fixedly connected to the outer wall of the spring 5, which works with the connecting post 6 for elastic reset. When the connecting post 6 is pressed, the spring 5 is compressed and deformed to store energy. Releasing the connecting post... After column 6, spring 5 releases energy to push connecting column 6 and inclined column 7 back to their original positions. One end of spring 5 is fixedly connected to the outer wall of connecting block 4. A groove 10 is provided on the inner wall of connecting block 4. The groove 10 is used to guide the sliding of pressing block 11, restricting the movement trajectory of pressing block 11 and ensuring that pressing block 11 can only slide in a straight line. A rotating shaft 9 is rotatably connected to the inner wall of connecting block 4. The rotating shaft 9 is used to provide a rotation fulcrum for rotating shaft 8, so that rotating shaft 8 can rotate stably around it, ensuring that the inclined thrust of inclined column 7 can be accurately converted. The rotational force of the rotating shaft 8 drives the pressing block 11 to slide, ensuring the linkage of the release component. The rotating shaft 8 is fixedly connected to the outer wall of the rotating shaft 9. The rotating shaft 8, together with the inclined column 7 and the pressing block 11, transmits power. One end of the rotating shaft 8 is pushed by the inclined surface of the inclined column 7 to rotate around the rotating shaft 9, and the other end drives the pressing block 11 to slide along the slide groove 10, transmitting the unlocking power to the fixing component, so as to realize the separation of the locking column 14 and the locking block 13. The anti-detachment column 15 is fixedly connected to the outer wall of the rotating shaft 8, and the fixing component is provided on the inner wall of the protection mechanism 3. The fixing component includes a locking block 13, which engages with a locking post 14 for secure locking. The locking block 13 is fixed to the inner wall of the protective mechanism 3, and its inner wall provides engagement space for the locking post 14. When the locking post 14 is engaged, it can lock the protective mechanism 3 relative to the base body 16. The outer wall of the locking block 13 is fixedly connected to the inner wall of the protective mechanism 3. The locking post 14 is provided on the inner wall of the locking block 13. The locking post 14 is used to lock the position of the protective mechanism 3. It engages or disengages from the locking block 13 under the action of the pressing block 11. Engaging secures the protective mechanism 3, and disengaging unlocks it, ensuring that the protective mechanism 3 is securely installed and easy to disassemble. The outer wall of the locking post 14 is fixed. A connecting plate 12 is fixedly connected to the locking post 14 and the pressing block 11. The sliding power of the pressing block 11 is transmitted to the locking post 14, so that the locking post 14 can move synchronously with the pressing block 11, ensuring the precise cooperation between the locking post 14 and the locking block 13. The pressing block 11 is fixedly connected to the outer wall of the connecting plate 12. The pressing block 11 is used to drive the movement of the locking post 14. It is driven by the rotating shaft 8 to slide along the slide groove 10, or it can be pressed directly by the operator. The outer wall of the pressing block 11 is slidably connected to the inner wall of the protection mechanism 3 and the inner wall of the connecting block 14. The outer wall of the connecting plate 12 and the outer wall of the locking post 14 are slidably connected to the inner wall of the protection mechanism 3.
[0020] Specifically, connecting block 4 provides installation space for inclined column 7, rotating shaft 8, etc.; pressing connecting column 6 causes inclined column 7 to slide and compress spring 5. Inclined column 7 pushes rotating shaft 8 to rotate around rotating shaft 9 through inclined surface, thereby causing pressing block 11 to slide along slide groove 10. After releasing connecting column 6, spring 5 pushes it to reset with inclined column 7. Locking block 13 is fixed in the protection mechanism 3. Pressing block 11 drives locking column 14 through connecting plate 12. When locking column 14 is locked into locking block 13, it locks the protection mechanism 3 and base body 16. When it is disengaged, it unlocks, ensuring that the protection mechanism 3 is stable and easy to disassemble.
[0021] Reference Figures 1-5The slide rail 2 has slots 17 inside, which provide engagement positions for the slider 19. Multiple slots 17 inside the slide rail 2 correspond to different positions of the base body 16. When the slider 19 is engaged, it can restrict the sliding of the base body 16 along the slide rail 2, thus fixing its position. A connecting block 21 is fixedly connected to the outer wall of the base body 16. The connecting block 21 is used to install the base position adjustment component. It is fixed to the outer wall of the base body 16, and the inner wall provides sliding space for the pull block 18, the inclined block 20, and the slider 19, ensuring that the adjustment component can be stably linked to achieve the fixing or unlocking of the base body 16 and the slide rail 2. The inner wall of the connecting block 21 is slidably connected to the pull block 18. The pull block 18 is used to trigger the position unlocking of the base body 16. When the operator pulls the pull block 18, it can drive the inclined block 20 to slide, thereby pushing the slider 19. 9. The pull block 18 is disengaged from the slot 17. An inclined block 20 is fixedly connected to the outer wall of the pull block 18. The inclined block 20 works with the pull block 18 and the slider 19 to perform inclined plane transmission. When the inclined block 20 slides with the pull block 18, it pushes the slider 19 to slide along the inner wall of the connecting block 21 through the inclined plane, converting the lifting motion of the pull block 18 into the linear motion of the slider 19. The slider 19 is slidably connected to the outer wall of the inclined block 20. The slider 19 works with the slot 17 to fix the position of the base body 16. When the slider 19 is disengaged from the slot 17 under the push of the inclined block 20, the position of the base body 16 can be adjusted by sliding. After the pull block 18 is released, the slider 19 is inserted into the slot 17 under its own restoring force, and the base body 16 is fixed again. The outer wall of the slider 19 is slidably connected to the inner wall of the connecting block 21. The outer wall of the slider 19 is slidably connected to the inner wall of the pull block 18 and the inner wall of the slide rail 2.
[0022] Specifically, the slot 17 of the slide rail 2 provides a locking point for the slider 19. Different slots 17 correspond to different positions on the base body 16. When the slider 19 is engaged, the base is fixed. The connecting block 21 of the base provides space for the pull block 18, the inclined block 20, etc. Pulling the pull block 18 causes the inclined block 20 to slide. The inclined block 20 pushes the slider 19 out of the slot 17 through the inclined surface, unlocking the base so that it can slide and be adjusted. Releasing the pull block 18 allows the slider 19 to reset and engage with the slot 17, re-fixing the base.
[0023] Working principle: When the protection device needs to be replaced quickly, firstly, by pressing the connecting column 6, the inclined column 7 is driven to slide along the inner wall of the connecting block 4, while the spring 5 is compressed to store elastic force. During the sliding process of the inclined column 7, the inclined surface drives the rotating shaft 8 to rotate around the rotating shaft 9 as the axis on the inner wall of the connecting block 4, thereby driving the pressing block 11 to slide on the inner wall of the connecting block 4, so that the locking column 14 on the connecting plate 12 is disengaged from the locking block 13 on the protection mechanism 3, and the protection device can be removed at the fastest speed. When the protection device needs to be installed quickly, the protection device is placed on the base body 16, and the pressing block 11 is pressed, so that the locking column 14 can be locked back into the locking block 13. Secondly, when it is necessary to adjust the position of the base body 16 on the slide rail 2, by pulling the pull block 18, it slides along the inner wall of the connecting block 21. The pull block 18 drives the inclined block 20 to move synchronously. Since the inclined block 20 is slidably connected to the outer wall of the slider 19, the movement of the inclined block 20 will push the slider 19 to slide on the inner wall of the connecting block 21. When the slider 19 disengages from the slot 17 inside the slide rail 2, the fixed relationship between the base body 16 and the slide rail 2 is released. At this time, the position of the base body 16 on the slide rail 2 can be adjusted. After the base body 16 moves to the target position, the pull block 18 is released, and the slider 19 slides down under its own restoring force and re-enters the slot 17 at the corresponding position of the slide rail 2, thereby fixing the base body 16 on the slide rail 2 again.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
