Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet installation technology, specifically to a top lifting ring structure for a power distribution cabinet. Background Technology
[0002] As a core piece of equipment in the power system and industrial control fields, the distribution cabinet requires lifting operations through top lifting rings during its production, warehousing, transportation, on-site installation, and subsequent maintenance. Whether it is being transferred from the production line to the warehouse in the factory or being lifted from the transport vehicle to the installation platform at the construction site, the lifting rings are the key components connecting the distribution cabinet to the lifting equipment. Their installation efficiency directly determines the operation rhythm throughout the entire life cycle of the distribution cabinet and has a significant impact on production capacity, construction period, and maintenance response speed.
[0003] Traditional lifting rings mostly use a "bolt-through" installation structure, which requires first aligning the lifting ring base with the mounting holes on the top of the distribution cabinet, and then using a wrench to screw in multiple fixing bolts one by one. Some structures also require adding nuts inside the distribution cabinet for double fixing.
[0004] There will also be situations where emergency construction is required. The traditional method of fixing the lifting rings is cumbersome and takes a long time, which cannot meet the requirements of rapid construction. Utility Model Content
[0005] The purpose of this utility model is to provide a top lifting ring structure for a power distribution cabinet to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A top lifting ring structure for a power distribution cabinet includes a power distribution cabinet, wherein the top of the power distribution cabinet has connection holes distributed at the four corners of the top of the power distribution cabinet; It also includes a connecting mechanism, a quick-fixing mechanism for lifting rings, and a sealing block; The connecting mechanism is disposed inside the connecting hole; The quick-fixing mechanism for the lifting ring is fixedly connected inside the connecting mechanism for quick installation of the lifting ring; The sealing block is used to seal the distribution cabinet after the lifting ring has been used.
[0007] A further improvement of the present invention is that the connecting mechanism includes a connecting block, the connecting block is inserted into the inside of the connecting hole, a fixing nut is threaded onto the surface of the connecting block, the connecting block is fixedly connected to the distribution cabinet through the fixing nut, a through hole is opened inside the connecting block, and a slot is opened on the inner wall of the through hole of the connecting block, the slots are distributed in a linear array.
[0008] A further improvement of the present invention is that the quick-fixing mechanism for the lifting ring includes a sleeve, which is inserted into the through hole of the connecting block. A limiting plate is fixedly connected to the surface of the sleeve, and a fixing block is fixedly connected to the top of the limiting plate. The lifting ring body is rotatably connected to the inside of the fixing block, and a quick-connecting assembly is provided inside the limiting plate.
[0009] A further improvement of this utility model is that: the quick-connect assembly includes snap-fit blocks, which are slidably connected to the left and right sides inside the limiting plate. A spring is fixedly connected to the top of the snap-fit block, and the end of the spring away from the snap-fit block is fixedly connected to the inner wall surface of the sleeve. A pressing rod is inserted into the middle of the two snap-fit blocks. The pressing rod is inclined inward from bottom to top. A button is fixedly connected to the top of the pressing rod. A spring is fixedly connected to the surface of the button. The end of the spring away from the button is fixedly connected to the top of the inner wall of the sleeve. Front and rear limiting blocks are provided on the front and rear sides of the pressing rod, and the front and rear limiting blocks are fixedly connected to the inner wall surface of the sleeve.
[0010] A further improvement of this utility model is that: the surface of the snap-fit block is fixedly connected with a snap-fit block that cooperates with the snap-fit slot.
[0011] A further improvement of this utility model is that the sealing block is inserted into the through hole of the connecting block, the sealing block is made of rubber, and the sealing block and the slot are interference fit.
[0012] The beneficial effects of this utility model are as follows: 1. This utility model provides a top lifting ring structure for a power distribution cabinet. When installing the lifting ring through the quick-fixing mechanism, simply insert the sleeve into the through hole of the connecting block. The spring elastically pushes the snap-fit block outward, so that the snap-fit block on the surface of the snap-fit block precisely engages with the snap-fit groove on the inner wall of the connecting block, thus completing the lifting ring fixation and achieving tool-free quick installation of the lifting ring. Compared with the traditional lifting ring installation method that requires repeated tightening of bolts with a wrench, this structure does not require additional tools and can significantly reduce the lifting ring installation time. Especially in scenarios where the power distribution cabinet needs to be hoisted at the factory, installed on site, or temporarily added for later maintenance, it can significantly reduce the operation time and improve the overall construction efficiency.
[0013] 2. This utility model provides a top lifting ring structure for a power distribution cabinet. Through the interference fit between the sealing block and the through hole of the connecting block, the gap inside the through hole can be tightly filled after the sealing block is inserted, effectively preventing external rainwater, dust, insects and other impurities from entering the power distribution cabinet. This can continuously provide a dry and clean operating environment for the power distribution cabinet, reduce equipment failures caused by external impurities, and extend the service life of the power distribution cabinet.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figure 1-5 As shown, this utility model has the following three specific embodiments.
[0019] Example 1 This utility model provides a top lifting ring structure for a power distribution cabinet, including a power distribution cabinet 11, characterized in that: a connection hole 12 is provided on the top of the power distribution cabinet 11, and the connection holes 12 are distributed at the four corners of the top of the power distribution cabinet 11. It also includes a connecting mechanism 2, a quick-fixing mechanism for the lifting ring 3, and a sealing block 41; The connecting mechanism 2 is located inside the connecting hole 12; The quick-fixing mechanism 3 for lifting rings is fixedly connected inside the connecting mechanism 2 for quick installation of lifting rings; The sealing block 41 is used to seal the distribution cabinet 11 after the lifting ring has been used.
[0020] In this embodiment, as Figure 1 As shown, the connecting mechanism 2 is first fixed in the connecting hole 12 on the top of the distribution cabinet to form a standardized interface. When hoisting is required, the sealing block 41 is removed first, and then the quick-fixing mechanism 3 of the lifting ring is inserted into the connecting mechanism 2 and locked. After hoisting is completed, the quick-fixing mechanism 3 of the lifting ring is removed, and then the sealing block 41 is inserted into the connecting mechanism 2 to restore the flatness and sealing of the top of the distribution cabinet 11 and prevent moisture and dust from entering the cabinet.
[0021] Example 2 The difference from Embodiment 1 is that this embodiment discloses a connecting mechanism 2 and a sealing block 41; Preferably, the connecting mechanism 2 includes a connecting block 21, which is inserted into the connecting hole 12. A fixing nut 23 is threaded onto the surface of the connecting block 21. The connecting block 21 is fixedly connected to the power distribution cabinet 11 through the fixing nut 23. A through hole is opened inside the connecting block 21, and a slot 22 is opened on the inner wall of the through hole of the connecting block 21. The slots 22 are distributed in a linear array.
[0022] The sealing block 41 is inserted into the through hole of the connecting block 21. The sealing block 41 is made of rubber and the sealing block 41 and the slot 22 are interference fit.
[0023] In this embodiment, as Figure 2 , 3 As shown in Figure 4, after inserting the connecting block 21 into the connecting hole 12, it is tightened from the bottom with the fixing nut 23 to make it firmly connected to the cabinet. Then, by pressing the sealing block 41 into the inside of the connecting block 21, the rubber undergoes elastic deformation and tightly fills the gap inside the connecting block 21, thus achieving a reliable seal.
[0024] Example 3 The difference from Embodiment 2 is that this embodiment discloses a quick-fixing mechanism 3 for the lifting ring; Preferably, the quick-fixing mechanism 3 for the lifting ring includes a sleeve 302, which is inserted into the through hole of the connecting block 21. A limiting plate 301 is fixedly connected to the surface of the sleeve 302. A fixing block 303 is fixedly connected to the top of the limiting plate 301. The lifting ring body 304 is rotatably connected inside the fixing block 303. A quick-connecting assembly is provided inside the limiting plate 301.
[0025] The quick-connect assembly includes a snap-fit block 305, which is slidably connected to the left and right sides inside the limiting plate 301. A spring 306 is fixedly connected to the top of the snap-fit block 305. The end of the spring 306 away from the snap-fit block 305 is fixedly connected to the inner wall surface of the sleeve 302. A pressing rod 307 is inserted into the middle of the two snap-fit blocks 305. The pressing rod 307 is inclined inward from bottom to top. A button 308 is fixedly connected to the top of the pressing rod 307. A spring 309 is fixedly connected to the surface of the button 308. The end of the spring 309 away from the button 308 is fixedly connected to the top of the inner wall of the sleeve 302. Front and rear limiting blocks 310 are provided on the front and rear sides of the pressing rod 307. The front and rear limiting blocks 310 are fixedly connected to the inner wall surface of the sleeve 302.
[0026] The surface of the snap-fit block 305 is fixedly connected with a snap-fit block that cooperates with the snap-fit slot 22.
[0027] In this embodiment, as Figure 3 and 5 As shown, by aligning the sleeve 302 of the lifting ring mechanism with and inserting it into the pre-embedded connecting block 21, and then pressing the button 308 downwards to move the pressing rod 307 downwards, the spring 309 is stretched, and the width of the contact part between the pressing rod 307 and the locking block 305 decreases. Then, the elastic force of the spring 306 drives the locking block 305 to move into the sleeve 302, and then the sleeve 302 is inserted into the connecting block 21. Then, the button 308 is released, the spring 309 contracts, and at the same time, the pressing rod 307 moves upwards and presses the locking block 305, so that the locking block on the locking block 305 is firmly locked into the fixing nut 22 to form an interlock. After the lifting is completed, the lifting ring quick fixing mechanism 3 can be removed by simply pressing the button 308 again to disengage the locking block 305 from the slot 22. The limiting block 310 is used to restrict the pressing 307 to move only in the vertical direction to prevent it from rotating.
[0028] The working principle of this utility model is as follows: After inserting the connecting block 21 into the connecting hole 12, it is secured from the bottom with the fixing nut 23 to firmly connect it to the cabinet. The slot 22 is an annular groove machined on the inner wall of the through hole inside the connecting block 21. It is a key structure for locking with the quick-connect assembly. By aligning and inserting the sleeve 302 of the lifting ring mechanism into the pre-embedded connecting block 21, and then pressing the button 308 downwards to move the pressing rod 307 downwards, the spring 309 is stretched, and the width of the contact portion between the pressing rod 307 and the locking block 305 decreases. Then, the elastic force of the spring 306 drives the locking block 305 to move into the sleeve 302, and then the sleeve 302 is inserted into the connecting block 21. Inside 1, then release button 308, spring 309 retracts, and at the same time drives the compression rod 307 to move upward, and squeezes the snap-fit block 305, so that the snap-fit block on the snap-fit block 305 is firmly snapped into the inside of the fixing nut 22 to form an interlock. After the hoisting is completed, just press button 308 again to make the snap-fit block 305 disengage from the snap-fit slot 22 to remove the quick fixing mechanism 3 of the lifting ring. By pressing the sealing block 41 into the inside of the connecting block 21, the rubber undergoes elastic deformation and tightly fills the gap inside the connecting block 21 to achieve a reliable seal.
