Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a low-voltage integrated distribution box with an emergency power supply quick-connect device. Background Technology

[0002] With modern society's increasing reliance on electricity, the reliability and safety of electrical equipment have become crucial concerns. Among numerous electrical devices, low-voltage integrated distribution boxes, as important power distribution devices in power systems, are widely used in industrial, commercial, and residential fields.

[0003] In related technologies, low-voltage integrated distribution boxes have a high degree of integration and high internal space utilization, and they mainly integrate functions such as power distribution, metering and monitoring, and overload / short circuit protection. Moreover, most low-voltage integrated distribution boxes are installed in the distribution room, and they need to be connected to other power distribution devices in the distribution room, which makes the space in the distribution room limited.

[0004] When a power outage occurs or an emergency power supply is needed, the low-voltage integrated distribution box usually requires an external generator. However, connecting the box to the generator is cumbersome and can easily prolong the power outage time. To improve this situation, an additional emergency power supply device is installed to deal with the above situations. However, if an emergency power supply device is added to the distribution room, it can easily lead to overcrowding in the distribution room, occupying the space used by other distribution devices and posing a safety hazard. Summary of the Invention

[0005] To improve space utilization, this application provides a low-voltage integrated distribution box with an emergency power supply quick-connect device.

[0006] A low-voltage integrated distribution box with an emergency power supply quick-connect device includes a cabinet. Inside the cabinet are an incoming line compartment, a metering compartment, and an outgoing line compartment. A wiring compartment is located between the incoming and outgoing line compartments. Below the wiring compartment, an emergency compartment is located directly below the wiring compartment and flush with the bottom surface of the cabinet. The emergency compartment is equipped with…

[0007] Emergency power supply module, including:

[0008] The socket box is equipped with quick-connect sockets, which are connected to power supply wires, which are connected to the wiring fittings in the wiring room.

[0009] The sliding component includes:

[0010] A gas spring is hinged to the cabinet. The drive rod of the gas spring is connected to a sliding plate, and the surface of the sliding plate is connected to the socket box.

[0011] The sealed door is slidably connected to the sliding plate, and the sealed door is hinged to a first guide rod, which is hinged to the cabinet body;

[0012] The sloping panel is connected to the cabinet body, and the gas spring abuts against the inclined surface of the sloping panel;

[0013] Locking components, including:

[0014] The locking block is rotatably connected to the cabinet body. The locking block is connected to the plug-in block through a locking spring. The plug-in block is inserted into the sealed door.

[0015] The unlocking block is slidably connected to the cabinet body. The unlocking block is connected to the cabinet body via an unlocking spring. The unlocking block is inserted into the locking block and matches the interior of the locking block.

[0016] The unlocking component is inserted into the unlocking block, and the unlocking component drives the unlocking block to be inserted into the locking block.

[0017] By adopting the above technical solution, the emergency compartment is located inside the cabinet and below the wiring compartment, which avoids increasing the cabinet surface area, reduces space occupancy, protects the electrical components inside the emergency compartment, avoids messy wiring, and increases the safety of the distribution box; the emergency power supply module can be quickly plugged into the generator in the event of a power outage; the sliding component can move the emergency power supply module out of or back into the distribution box, making it convenient for the emergency power supply module to be plugged into the generator; the locking component can fix the emergency power supply module in the emergency compartment to prevent accidental removal.

[0018] Optionally, the sliding assembly also includes a positioning frame that is slidably connected to the bottom of the cabinet. A first return spring is connected inside the positioning frame, and an abutment block is connected to the first return spring. When the power is not off, the positioning frame can slide from the cabinet to the sealed door and fix the sealed door with the insertion block. When the power is off, the positioning frame can slide from the sealed door to the cabinet. The gas spring drives the sealed door to abut against the bottom surface, and the gas spring pushes the sliding plate to insert into the positioning frame. The sliding plate abuts against the abutment block.

[0019] By adopting the above technical solution, when the power is not interrupted, the positioning frame and the plug-in block fix the sealing door, which can prevent the sealing door from being accidentally opened during the transportation of the cabinet; when the power is interrupted, the positioning frame slides to the cabinet, the gas spring drives the sealing door to abut against the bottom surface and pushes the sliding plate to insert into the positioning frame and abut against the abutment block, which facilitates the subsequent connection of the quick-connect socket to the generator to realize emergency power supply.

[0020] Optionally, the positioning frame is connected to a first snap-fit ​​block via a first snap-fit ​​spring. The first snap-fit ​​block passes through the positioning frame. A snap-fit ​​groove is provided on the sliding plate, and a handle is connected to the sliding plate. The handle drives the sliding plate to move the socket box. When the sliding plate is installed in place, the first snap-fit ​​block is inserted into the snap-fit ​​groove.

[0021] By adopting the above technical solution, the positioning frame, when not powered off, works with the plug-in block to fix the sealing door. When powered off, the gas spring pushes the sliding plate into the positioning frame to abut against the abutment block. The first snap-fit ​​block, the snap-fit ​​groove on the sliding plate, and the handle are connected by the first snap-fit ​​spring. When the handle drives the sliding plate to be installed in place, the first snap-fit ​​block is inserted into the snap-fit ​​groove, which can fix the position of the sliding plate, making it convenient for the staff to connect the generator to the quick-connect socket.

[0022] Optionally, the sliding assembly also includes a second guide rod, which is connected to the cabinet via a second return spring. A rotating block is connected to the side wall of the second guide rod, and the rotating block has an arc-shaped groove. The cabinet has a drive groove, and a limit groove is formed on the inner wall of the drive groove near the bottom of the cabinet. A second locking block is connected to the bottom of the limit groove via a second locking spring. When the sliding plate is installed in place, the second locking block extends into the arc-shaped groove and abuts against the arc-shaped bottom surface of the arc-shaped groove, and the rotating block extends into the limit groove.

[0023] By adopting the above technical solution, the second guide rod is connected to the cabinet through the second return spring, and the side wall of the second guide rod is connected to a rotating block with an arc-shaped groove. The bottom of the limiting groove opened near the bottom inner wall of the cabinet drive groove is connected to the second locking block through the second locking spring. When the sliding plate is installed in place, the second locking block extends into the arc-shaped groove and abuts against the arc-shaped bottom surface, and the rotating block extends into the limiting groove, which can further fix the position of the sliding plate and the socket box and improve the stability during use.

[0024] Optionally, a third return spring is connected to the sealing door, and the third return spring is connected to the sliding plate.

[0025] By adopting the above technical solution, a third reset spring is connected to the sealing door and connected to the sliding plate. When the sealing door is not in contact with the ground, the sliding plate can be prevented from sliding. When the sealing door is in contact with the ground, it can reduce the friction between the sealing door and the ground and the impact on the socket box when used with other components. It also helps to retract the sliding plate and the sealing door after use.

[0026] Optionally, the cabinet body has a locking groove, and the locking block is rotatably connected to the inner wall of the locking groove via a torsion spring. The sealing door has a lock hole, and the cabinet body has a clearance groove that communicates with the lock hole. After the plug-in block rotates, it can extend into the clearance groove.

[0027] By adopting the above technical solution, the sealed door has a lock hole and the cabinet has a clearance groove. With the help of a rotatable plug block, the sealed door can be locked under normal conditions. When unlocking, the plug block is rotated into the clearance groove to unlock the sealed door. This ensures the airtightness of the emergency room and the stable storage of the emergency power supply module, and also facilitates operation in emergencies.

[0028] Optionally, the unlocking block has a polygonal cross-section, and the locking block has a first rotating groove that matches the unlocking block; the unlocking component has a polygonal cross-section, and the unlocking block has a second rotating groove that matches the unlocking component; the unlocking component extends into the unlocking block and drives the unlocking block to connect with the locking block.

[0029] By adopting the above technical solution, an unlocking block and an unlocking component with a polygonal cross-section are set, along with a first rotating groove and a second rotating groove that match them. This facilitates the unlocking component to extend into the unlocking block and drive the unlocking block to connect with the locking block. The polygonal structure enables effective drive transmission, ensuring the smooth progress of the unlocking operation and thus unlocking the sealed door so that the emergency power supply module can be moved out of the distribution box when needed.

[0030] Optionally, the inner walls of the second rotating slots are slidably connected with metal blocks, the unlocking component is a permanent magnet made of neodymium iron boron permanent magnet material, and the side wall of the unlocking component is provided with a groove that matches the metal block. The unlocking block is connected to a cylindrical connecting rod.

[0031] By adopting the above technical solution, the metal block slidably connected in the second rotating groove, the permanent magnet unlocking component made of neodymium iron boron permanent magnet material, and the groove on its side wall use magnetic attraction to make the metal block extend into the groove, which can pull the unlocking block and the locking block to match and plug in, improving the accuracy and stability of the unlocking operation. When unlocking, the metal block hits the bottom of the groove and makes a metallic impact sound, which can serve as a prompt. The markings on the surface of the cylindrical connecting rod connected to the unlocking block can ensure that the unlocking block and the locking block are installed in place.

[0032] Optionally, a dustproof plate is rotatably connected to the socket box, and the dustproof plate covers the quick-connect socket.

[0033] By adopting the above technical solution, the dustproof plate can prevent damage to the insertion end of the quick-connect socket and can abut against the cover plate of the quick-connect socket to prevent the cover plate from being accidentally opened during the sliding of the socket box, while also preventing damage to the surface of the cover plate.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. The emergency compartment is located inside the cabinet, which avoids increasing the cabinet's surface area and reduces space occupancy. Furthermore, its location below the wiring compartment prevents cluttered internal wiring and increases the safety of the distribution box.

[0036] 2. The emergency power supply module, in conjunction with the sliding component, allows the socket box to be quickly moved out in the event of a power outage, facilitating rapid connection with the generator to achieve emergency power supply, thus solving the problems of cumbersome operation and inability to quickly supply power in traditional methods;

[0037] 3. The locking component works in conjunction with the positioning frame to fix the emergency power supply module in the emergency compartment, preventing it from being accidentally moved, shaken, or damaged during transportation and daily use, thus solving the problem of poor storage and fixation of emergency devices.

One side of the cabinet 1 has an inlet compartment 2 and a metering compartment 3, while the other side has an outlet compartment 4. A wiring compartment 5 is located between the inlet compartment 2 and the outlet compartment 3. Below the wiring compartment 5, the cabinet 1 has an emergency compartment 6 that communicates with the wiring compartment 5. The emergency compartment 6 is located inside the cabinet 1. Compared to being installed on the side of the cabinet 1, this effectively avoids increasing the surface area of ​​the cabinet 1 and reduces its space occupancy. Furthermore, compared to being installed at the bottom of the cabinet 1, it effectively protects the electrical components inside the emergency compartment 6, preventing damage. The emergency compartment 6 is located below the wiring compartment 5, which, compared to being above the wiring compartment 5, effectively avoids cluttered internal wiring and increases the safety of the distribution box. Furthermore, the emergency room 6 is equipped with an emergency power supply module 7, a sliding assembly 8, and a locking assembly 9. The emergency power supply module 7 is used to quickly connect to the generator when the power is off. The sliding assembly 8 is used to move the emergency power supply module 7 out of or back into the distribution box to facilitate the connection between the emergency power supply module 7 and the generator. The locking assembly 9 is used to fix the emergency power supply module 7 in the emergency room 6 to prevent the emergency power supply module 7 from being accidentally moved out.

[0052] Reference Figure 3 , Figure 4 The emergency power supply module 7 includes a socket box 701. The socket box 701 has a socket cavity, through which multiple quick-connect sockets 702 are connected. The quick-connect sockets 702 are fixedly connected to the socket box 701 with bolts, ensuring that the insertion end of the quick-connect socket 702 extends outside the socket box 701, while the wiring section of the quick-connect socket 702 is inside the socket box 701. A power supply wire 703 passes through the socket box 701. One end of the power supply wire 703 is connected to the wiring end of the quick-connect socket 702, and the other end is connected to a wiring component in the wiring compartment 5. An insulating sleeve is fitted onto the surface of the power supply wire 703 to prevent damage and effectively prevent leakage.

[0053] The quick-connect socket 702 is rotatably connected to a cover plate 704, which covers the insertion end of the quick-connect socket 702 to prevent damage. Additionally, a dustproof plate 705 is rotatably connected to the surface of the socket box 701. The dustproof plate 705 is made of a light-transmitting, wear-resistant plastic material. After rotation, the dustproof plate 705 snaps into the surface of the socket box 701 and covers the cover plates 704 of the multiple quick-connect sockets 702. Furthermore, the dustproof plate 705 abuts against the cover plate 704, effectively preventing the socket box 701 from accidentally opening during sliding, and also preventing damage to the surface of the cover plate 704.

[0054] Reference Figure 3 , Figure 4 , Figure 5The sliding assembly 8 includes a sealing door 801. A connection port is provided on the bottom surface of the cabinet 1. A rubber sealing strip 802 is fixedly connected to the sealing door 801, and the side wall of the sealing strip 802 abuts against the inner wall of the cabinet 1 at the connection port. A sliding groove 10 is provided on the upper surface of the sealing door 801. A sliding opening is provided on one side of the sliding groove 10. Multiple third return springs 803 are fixedly connected to the side wall opposite the opening of the sliding groove 10. A sliding plate 804 is fixedly connected to the end of each third return spring 803. The sliding plate 804 is fixedly connected to the socket box 701 by bolts. Sliding shafts 806 are rotatably connected to both sides of the sliding plate 804 near the connection point with the third return springs 803. The sliding shafts 806 extend into the sliding groove 10. A limit block 805 is fixedly connected to the inner wall of the sealing door 801 near the sliding opening of the sliding groove 10.

[0055] Reference Figure 3 , Figure 6 Two fixing plates 11 are fixedly connected to both sides of the connection port of the cabinet 1. A sloped panel 807 is fixedly connected to the opposite side of the two fixing plates 11. The sloped panel 807 has a right trapezoidal cross-section, and the side of the sloped panel 807 is fixedly connected to the surface of the fixing plate 11 of the cabinet 1. A gas spring 808 is connected to the fixing plate 11 above the sloped panel 807 by a hinge. The surface of the gas spring 808 abuts against the sloped surface of the sloped panel 807, so that the gas spring 808 and the bottom surface of the cabinet 1 form an angle between 70° and 80°. The drive rod of the gas spring 808 is rotatably connected to the sliding plate 804 by a hinge, thereby tilting and pushing out the sliding plate 804 and the sealing door 801. When the sealing door 801 abuts against the bottom surface, the gas spring 808 can further push the upper part of the sliding plate 804 along the sliding groove 10 away from the connection between the third return spring 803 and the sealing door 801.

[0056] Specifically, the gas spring 808 pushes the sliding plate 804 to slide along the sliding groove 10 away from the connection between the third return spring 803 and the sealing door 801, the sliding shaft 806 rolls in the sliding groove 10, and the third return spring 803 deforms and stretches; the sliding plate 804 further slides away from the third return spring 803 and extends out of the sealing door 801 from the sliding opening, and when the sliding plate 804 is installed in place, the sliding shaft 806 abuts against the limit block 805, and facilitates the operator to connect the generator to the quick-connect socket 702.

[0057] Each of the two fixed plates 11 has a first guide rod 809 connected to its opposite side by a hinge. The first guide rod 809 is located on the side of the fixed plate 11 away from the third return spring 803. A first telescopic rod is slidably connected inside the first guide rod 809. The end of the first telescopic rod is connected to the sealing door 801 by a hinge. In addition, a positioning block 12 is fixedly connected to the fixed plate 11. The positioning block 12 has an inclined surface. When the sealing door 801 is in contact with the ground, the first telescopic rod abuts against the positioning block 12.

[0058] Mounting plates 13 are fixedly connected to the opposite sides of the two fixed plates 11, and the mounting plates 13 are located on the fixed plates 11 on the side close to the third return spring 803. The bottom surface of the mounting plates 13 is fixedly connected to the second return spring 810, and the end of the second return spring 810 is fixedly connected to the second guide rod 811. The end of the second guide rod 811 is connected to the sliding plate 804 by a hinge.

[0059] Reference Figure 3 , Figure 6 , Figure 7 A rotating block 14 is fixedly connected to the side wall of the second guide rod 811, and an arc-shaped groove 15 is provided on the arc-shaped side of the rotating block 14. The inner wall of the arc-shaped groove 15 smoothly transitions with the arc-shaped surface of the rotating block 14. In addition, a drive groove 16 is provided on the fixed plate 11. The drive groove 16 is opened at an angle and its inclination angle matches and corresponds to the gas spring 808. A limit groove 17 is provided on the inner wall of the drive groove 16 near the bottom of the cabinet 1. The bottom of the limit groove 17 is connected to a second locking block 19 through a second locking spring 18, and the second locking block 19 is a spherical block.

[0060] When the sliding plate 804 moves, the rotating block 14 rotates, at which time the second locking block 19 abuts against the arc-shaped surface of the rotating block 14; when the sliding plate 804 extends out of the sealing door 801 from the sliding opening, and when the sliding plate 804 is installed in place, the second return spring 810 deforms and stretches, and at the same time, the second locking block 19 extends into the arc-shaped groove 15 and abuts against the arc-shaped bottom surface of the arc-shaped groove 15, and the rotating block 14 extends into the limiting groove 17.

[0061] Reference Figure 3 , Figure 8The bottom outer surface of the cabinet 1 has a connecting groove 20, in which a positioning frame is slidably connected. The bottom of the connecting groove 20 is snapped into the positioning frame. The positioning frame consists of two positioning plates 812, and each positioning plate 812 has a movable block rotatably connected to its bottom surface. Additionally, the bottom surface of the sealing door 801 has a through groove 21 that communicates with and matches the connecting groove 20, and the bottom of the through groove 21 is snapped into the positioning plate 812. When the sealing door 801 is closed, the positioning plate 812 can slide along the connecting groove 20 into the through groove 21 and snap into the bottom of the through groove 21, so that part of the positioning plate 812 is located in the through groove 21 and the other part is located in the connecting groove 20. This provides support and locking for the sealing door 801, effectively preventing the sealing door 801 from accidentally opening during transportation.

[0062] Reference Figure 3 , Figure 8 , Figure 9 The two positioning plates 812 have positioning grooves 22 on their opposite sides. The first return spring 813 is fixedly connected to the inner wall of the positioning groove 22 near the side of the cabinet 1. The end of the first return spring 813 is fixedly connected to the abutment block 23. When the gas spring 808 drives the sliding plate 804 to extend into the positioning groove 22, and the abutment block 23 abuts against the sliding plate 804, the first return spring 813 deforms and contracts.

[0063] Reference Figure 4 , Figure 6 , Figure 9 A first locking block 24 passes through one side of the two positioning plates 812 that are far apart from each other, and a first locking spring 25 is fixedly connected to the side of the first locking block 24. The first locking spring 25 is offset from the first reset spring 813. Under the action of the first locking spring 25, the first locking block 24 extends into the positioning groove 22. In addition, a locking groove 26 is opened on the side of the sliding plate 804, and a handle is fixedly connected to the surface of the sliding plate 804.

[0064] When the gas spring 808 abuts against the first return spring 813 and their elastic thrusts are consistent, the sliding plate 804 stops sliding. At this time, the operator pulls the sliding plate 804 further by the handle, so that the drive rod of the gas spring 808 tilts and extends, the first return spring 813 deforms and contracts, and when the sliding plate 804 is installed in place, the first locking block 24 extends into the locking groove 26, thereby fixing the position of the sliding plate 804.

[0065] Reference Figure 3 , Figure 10 , Figure 11The locking component 9 includes a locking block 901, an unlocking block 902, and an unlocking element 903. Additionally, a locking groove 27 is provided at the bottom of the cabinet 1. A fixing ring 904 is fixedly connected to the inner wall of the locking groove 27. The upper end face of the fixing ring 904 is rotatably connected to the locking block 901. A torsion spring 905 is fitted over the locking block 901. One end of the torsion spring 905 is fixedly connected to the fixing ring 904, and the other end of the torsion spring 905 is fixedly connected to the surface of the locking block 901.

[0066] The locking block 901 has a slot 28 on its surface. A locking spring 906 is fixedly connected to the bottom of the slot 28, and a slot 907 is fixedly connected to the end of the locking spring 906. The bottom surface of the slot 907 has an inclined surface, and the end of the slot 907 is rounded. The sealing door 801 has a lock hole 29 that communicates with the locking slot 27. The lock hole 29 is located on the same side as the connection between the third return spring 803 and the sealing door 801. When the sealing door 801 is closed, the slot 907 extends into the lock hole 29, causing the slot 907 to abut against the inner wall of the lock hole 29.

[0067] An unlocking spring 908 is fixedly connected to the bottom of the locking groove 27. The end of the unlocking spring 908 is fixedly connected to the unlocking block 902. The unlocking block 902 has a hexagonal cross-section, and a first rotating groove 30 matching the shape of the unlocking block 902 is formed within the locking block 901. Simultaneously, the unlocking member 903 also has a hexagonal cross-section. A cylindrical connecting rod 909 is fixedly connected to one end of the unlocking member 903, and a second rotating groove 31 matching the shape of the unlocking block 902 is formed within the unlocking block 902. Metal blocks 910 are slidably connected to the alternating inner walls of the second rotating grooves 31. A groove 32 matching the metal block 910 is formed on the side wall of the unlocking member 903, and the inner wall of the groove 32 near the connecting rod 909 smoothly transitions to the surface of the unlocking member 903. Meanwhile, the unlocking component 903 is a permanent magnet made of neodymium iron boron permanent magnet material. After the unlocking component 903 is matched and inserted into the unlocking block 902, the metal block 910 extends into the groove 32 under the action of magnetic attraction, thereby pulling the unlocking block 902 to match and insert with the locking block 901. In addition, the surface of the connecting rod 909 is marked with a mark 33 to ensure that the unlocking block 902 and the locking block 901 are installed in place.

[0068] The implementation principle of this application embodiment is as follows: When the power is off, the operator first pulls the positioning frame out of the through groove 21 of the sealing door 801, causing the positioning frame to slide into the connecting groove 20. When the positioning frame is installed in place, the positioning frame is locked to the bottom of the connecting groove 20. Next, the operator holds the connecting rod 909 of the unlocking component 903 and inserts it through the fixing ring 904, so that the unlocking component 903 is inserted into the unlocking block 902, and the groove 32 of the unlocking component 903 is aligned with the metal block 910 of the unlocking block 902. Thus, the metal block 910 extends into the groove 32 under the action of magnetic attraction. When the unlocking component 903 and the unlocking block 902 are correctly connected, the metal block 910 will strike the bottom of the groove 32, thus producing a metallic impact sound, which serves as a prompt.

[0069] After the unlocking component 903 and the unlocking block 902 are correctly connected, the operator can pull down the connecting rod 909 to slide the unlocking block 902 toward the locking block 901, at which time the unlocking spring 908 deforms and stretches. When the unlocking block 902 is inserted into the first rotating groove 30 of the locking block 901, the operator can check the marking 33 on the surface of the connecting rod 909 to ensure that the unlocking block 902 and the locking block 901 are installed in place. After they are installed in place, the operator can rotate the connecting rod 909, thereby causing the unlocking block 902 to rotate within the locking block 901, thereby causing the insertion block 907 within the locking block 901 to rotate from the lock hole 29 of the sealing door 801 into the clearance groove, thus unlocking the sealing door 801.

[0070] Furthermore, after the unlocking component 903 is unlocked, the operator can push the connecting rod 909 upwards, at which point the unlocking spring 908 deforms and contracts, thereby accelerating the upward speed of the unlocking block 902. When the operator pushes the connecting rod 909, the metal block 910 of the unlocking block 902 slides out of the groove 32 of the unlocking component 903 near the connecting rod 909, thus disengaging the unlocking block 902 from the unlocking component 903. Then, rotating the rotating rod causes the metal block 910 of the unlocking block 902 to displace from the groove 32 of the unlocking component 903. Finally, the operator can pull out the unlocking component 903 using the connecting rod 909. It should be noted that when the unlocking block 902 disengages from the locking block 901, the locking block 901 rotates back to its original position under the action of the torsion spring 905, causing the insertion block 907 to rotate out of the clearance groove.

[0071] After the unlocking component 903 is unlocked, the gas spring 808 drive rod automatically and slowly extends. Under the action of the slope panel 807, the gas spring 808 tilts to separate the sealing door 801 from the cabinet 1, and drives the first telescopic rod of the first guide rod 809 to extend, while the second guide rod 811 slides in the drive groove 16.

[0072] When the sealing door 801 is not in contact with the ground, the sealing door 801 can prevent the sliding plate 804 from sliding by the third return spring 803. The first guide rod 809 and the second guide rod 811 gradually rotate during the sliding of the sealing door 801. In addition, since the second guide rod 811 is fixed to the mounting plate 13 of the fixed plate 11 by the second return spring 810, the end of the sealing door 801 that is in the same direction as its horizontal movement is raised. In this way, when the sealing door 801 is in contact with the ground, the friction between the sealing door 801 and the ground can be reduced, and the impact on the socket box 701 when the sealing door 801 is in contact with the ground can also be reduced.

[0073] When the sealing door 801 contacts the ground, the first guide rod 809 contacts the inclined surface of the positioning block 12. The drive rod of the gas spring 808 continues to extend and further pushes the sliding plate 804 to slide, and drives the second guide rod 811 to slide further along the drive groove 16, so that the sliding plate 804 extends out of the sliding opening of the sealing door 801 and slides into the positioning groove 22. At this time, the third return spring 803 is stretched due to the sliding deformation of the sliding plate 804. In addition, the second return spring 810 is stretched under the action of the rotation and sliding of the second guide rod 811. The first return spring 813 in the positioning groove 22 is contracted due to the thrust of the gas spring 808. When the deformation elastic force of the first, second and third return springs is equal to the thrust of the gas spring 808, the sliding plate 804 stops sliding in the positioning groove 22, and at this time the sliding plate 804 is not installed in place.

[0074] After the sliding plate 804 stops sliding, the operator can pull the handle on the sliding plate 804, causing the first return spring 813 to further deform and contract, and the second and third return springs to further deform and stretch. During this process, the rotating block 14 of the second guide rod 811 gradually rotates, causing the second locking block 19 to extend into the arc-shaped groove 15 and gradually slide along the inner wall of the arc-shaped groove 15 towards the arc-shaped bottom surface of the arc-shaped groove 15. At the same time, the rotating block 14 slides along the drive groove 16 and gradually extends into the limiting groove 17. Furthermore, when the sliding plate 804 is installed in place, that is, when the sliding plate 804 is snapped into the positioning frame, the second locking block 19 abuts against the arc-shaped bottom surface of the arc-shaped groove 15 of the rotating block 14, and the first locking block 24 is inserted into the locking groove 26 of the sliding plate 804, thereby fixing the position of the sliding plate 804.

[0075] When in use, the operator can open the dust cover 705 and the cover 704 in sequence, and insert the generator connector into the plug socket to connect the circuit.

[0076] After use, the staff can pull the first locking block 24 outward to disengage the first locking block 24 from the sliding plate 804, thereby releasing the first and third reset springs. At this time, the thrust generated by the release of the first and third reset springs is greater than the thrust of the gas spring 808, and this thrust can push it out of the positioning frame and cause the sliding plate 804 to retract into the sealing door 801. At the same time, the rotating block 14 gradually slides away from the bottom of the groove 17, and the second locking block 19 slides along the arc groove 15 of the rotating block 14. The drive rod of the gas spring 808 retracts, and the gas spring 808 slides towards the inclined surface of the slope panel 807. When the sliding plate 804 disengages from the positioning frame, the third reset spring 803 returns to its normal state or deforms and retracts, and the gas spring 808 abuts or contacts the inclined surface of the slope panel 807, the second locking block 19 abuts against the surface of the rotating block 14, and the second locking block 19 pushes the rotating block 14 out of the limiting groove 17 under the action of the second locking spring 18.

[0077] When the rotating block 14 slides out of the limiting groove 17, the second return spring 810 is released. At this time, the pulling force generated by the release of the second return spring 810 is greater than the pushing force of the gas spring 808. This pushing force can pull the sliding plate 804 and the sealing door 801, causing the sealing door 801 to slide closer to the cabinet 1. In addition, during the sliding process of the sealing door 801, the sealing door 801 presses the plug-in block 907, causing the plug-in block 907 to extend into the plug-in groove 28. When the lock hole 29 is aligned with the plug-in groove 28, the plug-in block 907 extends into the lock hole 29 under the action of the locking spring 906. At this time, the sealing strip 802 of the sealing door 801 abuts against the inner wall of the connection port, which can reduce the impact of the sealing door 801 on the cabinet 1. At the same time, the friction formed by the abutment of the two can initially fix the sealing door 801. Finally, the staff pushes the positioning frame to disengage it from the bottom of the connecting groove 20, pushes the positioning frame into the through groove 21, and secures the positioning frame to the bottom of the through groove 21.
