[0032] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

[0034] When the operator needs to lock the pull plate 5, first place the hand steadily on the edge of the pull plate 5 where the force is easy to apply, keep the body posture stable, and push the pull plate 5 along the track direction of the sliding guide 4 with uniform and moderate force. During the pushing process, the movement track of the pull plate 5 needs to be observed to ensure smooth sliding along the inner arc surface of the sliding guide 4, avoiding the pull plate 5 from deviating or jamming due to uneven force. As the pull plate 5 gradually approaches the target position, the pre-installed pressing plate 61 shows a tendency to tilt towards the side base body 62 under the continuous pulling force of the tension spring 622. When the pull plate 5 reaches the predetermined locking position, the clamping end 611 of the pressing plate 61 will automatically and quickly clamp down on the upper surface of the side base body 62 at a precise angle under the pulling force of the tension spring 622. At this time, the clamping end 611 will produce a slight "click" sound when it contacts the upper surface of the side base body 62, thereby completing the clamping.
[0035] At the same time, the bent edge 612 at the bottom of the front end of the pressing plate 61 will naturally slide into the inner side wall of the hook part 63 along the outer side wall of the side base body 62, completing the precise clamping action. At the moment when the bent edge 612 clamps into the inner side wall of the hook part 63, the operator can feel a significant change in resistance through the hand and observe that the bent edge 612 tightly fits the inner side wall of the hook part 63 without obvious gaps. At this point, the double locking structure is completed. After locking, the operator needs to check the locking state. On the one hand, the fit between the clamping end 611 and the side base body 62 is observed carefully with the naked eye. In the ideal state, the two should be completely fitted. The embedding depth of the bent edge 612 and the hook part 63 ensures that it reaches the depth. If the fit or embedding depth is not up to standard, the pull plate 5 needs to be pushed again for locking operation. Through the clamping of the clamping end 611 and the upper surface of the side base body 62, and the cooperation of the bent edge 612 and the inner side wall of the hook part 63, a double locking structure is formed. Compared with the traditional single locking method, the stability of the pull plate 5 after locking is significantly improved. Even if the ring main unit is subjected to external vibration and impact during operation, the pull plate 5 is not easy to displace, ensuring the position of the internal components and reducing the risk of faults caused by loose components, effectively ensuring the safe and stable operation of the power equipment.
[0036] When it is necessary to unlock the pull plate 5, the operator places his fingers above the press plate 613 of the pressure plate 61, evenly exerts force, and smoothly applies downward pressure. During the application of pressure, avoid damaging the pressure plate 61 due to excessive force or being unable to complete the unlocking due to insufficient force. After the press plate 613 is subjected to the pressure applied by the fingers, it will serve as a fulcrum to rotate the pressure plate 61 as a whole upward. During the rotation of the pressure plate 61, the clamping end 611 will gradually lift upward and separate from the upper surface of the side base body 62. During this process, a gradually expanding gap between the clamping end 611 and the side base body 62 can be observed. At the same time, the bent edge 612 will also slide upward along the inner wall of the hook portion 63 and eventually disengage from the hook portion 63.
[0037] During the entire unlocking process, the operator should closely observe the rotation of the pressure plate 61 and the separation state of the clamping end 611 and the bent edge 612 from the side base body 62. When it is confirmed that the clamping end 611 is completely separated from the side base body 62 and the bent edge 612 is completely disengaged from the hook portion 63, the pressure plate 61 is in a completely unlocked state at this time.
[0038] After the pressure plate 61 is completely unlocked, the operator again places his hand on the edge of the pull plate 5 and slides the pull plate 5 at a smooth and slow speed. During the sliding process, if the operator feels that the pull plate 5 is stuck, he should immediately stop the sliding operation, recheck whether the pressure plate 61 is completely unlocked and whether there is a component jamming or damage, and continue the sliding operation after troubleshooting, thereby avoiding damage to the pull plate 5 or the interlocking mechanism 6 due to incomplete unlocking. When pushing the pull plate 5 to the target position, the pressure plate 61 automatically completes the clamping action under the action of the tension spring 622, without the need for additional complex manual operation by the operator. This design simplifies the locking process, significantly shortens the operation time during equipment installation, debugging, or daily maintenance, improves work efficiency, and is especially suitable for scenarios that require frequent component position fixing.
[0039] As shown in Figure 3 , Figure 7 and Figure 8 , the composite sealing assembly 7 includes a corrosion-resistant sleeve 71 movably sleeved in the inner arc surface of the threading hole 651. The inner arc surface of the corrosion-resistant sleeve 71 is sleeved with a barrier thick sleeve 72. The inner arc surface of the barrier thick sleeve 72 is sleeved with a sealing ring 73 at one side edge. A boss 74 is fixedly installed in the middle of the inner arc surface of the side away from the sealing ring 73 of the barrier thick sleeve 72. The inner arc surface of the boss 74 is sleeved with a protective circular cover 75. The inner arc surface of the protective circular cover 75 is fixedly installed with a spring 76. The inner arc surface of the protective circular cover 75 is connected with a looped network line 77.
[0040] From one end of the threading hole 651, slowly sleeve the corrosion-resistant sleeve 71 into the process needs to use a special concentric positioning tool, ensure that the corrosion-resistant sleeve 71 is strictly coaxial with the threading hole 651, avoid eccentricity if there is eccentricity, not only will reduce the sealing effect, also may cause stress concentration, affect the insulation performance after the completion of the corrosion-resistant sleeve 71 installation, in the same way sleeve into the barrier thick sleeve 72 after the sealing ring 73 is evenly coated with high temperature resistant, aging resistant sealant, carefully sleeve in the inner arc surface side edge of the barrier thick sleeve 72, using a special pressing tool, according to the order from the center to the edge, gradually light pressure sealing ring 73, make the sealing ring 73 and the barrier thick sleeve 72 fully adhere to, ensure that the sealant is evenly distributed, eliminate bubbles and gaps, corrosion-resistant sleeve 71 is made of special high molecular anti-corrosion material, its molecular structure is dense and has excellent chemical stability when the external corrosive gas or liquid contacts the surface of the corrosion-resistant sleeve 71, its molecular structure can effectively prevent the penetration of corrosive medium, form a solid protective barrier for example, in the coastal areas and other salt spray environment, corrosion-resistant sleeve 71 can resist salt spray erosion for a long time, protect the internal insulation structure from being damaged, thereby prolonging the service life of the ring network cabinet and reducing the risk of failure caused by corrosion.
[0041] The barrier thick sleeve 72 and the sealing ring 73 are closely matched to build a high-efficiency sealed space at the threading hole 651. The sealing ring 73 is made of materials such as silicon rubber with good elasticity, which can form a tight wrapping around the ring network line 77. When external moisture, dust and other impurities attempt to enter the interior of the ring network cabinet, the elastic deformation of the sealing ring 73 can effectively block the gaps and prevent impurities from invading. At the same time, the barrier thick sleeve 72 also has certain sealing performance, which cooperates with the sealing ring 73 to further enhance the sealing effect, prevent the insulation performance from being reduced due to moisture, avoid short circuit and other faults caused by dust accumulation, and ensure the safe and stable operation of the ring network cabinet.
[0042] As shown in Figure 3 , Figure 4 and Figure 6 , the outer arc surface of the shaft rod 642 is sleeved with a disassembly mechanism 8. The disassembly mechanism 8 includes a guide cam 81 connected through the middle of the outer arc surface of the shaft rod 642. A slot hole is formed on the side of the guide cam 81 close to the shaft rod 642. The slot hole on one side of the guide cam 81 is in sliding connection with the shaft rod 642. The outer arc surface of the guide cam 81 is provided with a protruding portion 82. The protruding portion 82 is movably connected to the inner arc surface of the guide cam 81 through a rotating shaft. A slot 83 is formed between the guide cam 81 and the protruding portion 82. A clamping element 84 is movably sleeved on the inner arc surface of the slot 83. A pin column 841 is connected to the clamping element 84 close to the slot 83. The outer arc surface of the pin column 841 is movably connected to the inside of the slot 83. A back plate 85 is fixedly installed on one side surface edge of the clamping element 84. The back plate 85 is fixedly connected between the two side base bodies 62.
[0043] Align the slot hole of the guide cam 81 with the shaft 642, slowly slide the sleeve into the outer arc surface of the shaft 642, and ensure that the guide cam 81 can slide freely on the shaft 642 during installation, and that there is no obvious gap between the slot hole and the shaft 642, to avoid the guide cam 81 from shaking and affecting the disassembly operation. Insert the shaft at the bottom of the outer arc surface of the guide cam 81, and insert the protruding part 82 into the shaft to make the protruding part 82 rotate flexibly around the shaft. After installation, check the rotation range of the protruding part 82 to ensure that it can normally move in the slot 83 without jamming. Align the pin 841 of the clamping element 84 with the slot 83 between the guide cam 81 and the protruding part 82, and gently push it in to make the pin 841 clamped inside the slot 83. When installing, pay attention to the installation direction of the clamping element 84 to ensure that it can effectively clamp the related parts. Use bolts to fix the rear plate 85 between the two side bodies 62 to ensure that the rear plate 85 is firmly installed and can provide stable support for the clamping element 84. When fixing the rear plate 85, the bolts need to be tightened symmetrically to avoid deformation of the rear plate 85 due to uneven stress.
[0044] When disassembling the related parts, the operator uses a special tool to rotate the guide cam 81. During the rotation of the guide cam 81, the protruding part 82 at the bottom of the outer arc surface moves in the slot 83, driving the clamping element 84 to act. With the rotation of the guide cam 81, the clamping element 84 gradually releases the clamping state of the related parts. When the clamping element 84 is completely loosened, the target part can be easily disassembled. The entire disassembly process does not require complex tools or tedious operations, improving the efficiency of equipment maintenance.
