Description

Technical Field

[0001] This utility model relates to the field of isolator technology, and in particular to a quick-release structure for a power distribution isolator. Background Technology

[0002] In power distribution systems, isolators serve as critical safety protection devices, primarily providing a clear disconnection point during equipment maintenance or line upkeep to ensure electrical isolation safety. Traditional isolators commonly employ bolted or welded installation methods. While this rigid connection ensures structural strength, it has significant shortcomings in practical applications: disassembly and assembly require specialized tools to tighten and loosen bolts individually, making the process cumbersome and time-consuming; in space-constrained distribution cabinets, tool operation is particularly inconvenient, severely impacting maintenance efficiency; after long-term operation, metal components are prone to oxidation and corrosion, leading to disassembly difficulties; simultaneously, the lack of continuous lubrication in sliding parts increases frictional resistance, accelerating mechanical wear on contact surfaces and potentially causing jamming of the operating mechanism, affecting the reliability of opening and closing. These defects significantly increase equipment maintenance costs and safety hazards.

[0003] In existing technologies, some quick-release structures use simple plug-in or snap-on designs, but these often suffer from problems such as insecure locking and easy loosening, affecting the reliability of equipment operation. At the same time, the lack of effective lubrication design leads to accelerated wear of sliding parts and shortens their service life. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick-release structure for a power distribution isolator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a connecting plate, the surface of which is provided with a sliding strip, the bottom of which is provided with a limit slot, a sliding block is slidably connected to the surface of which is a sliding block, the surface of which is provided with an isolator body, and the top and bottom of which are provided with external connecting pieces.

[0006] Preferably, the outer piece has a threaded opening inside, and an external screw is threaded into the threaded opening.

[0007] Preferably, a lubrication groove is provided on one side of the surface of the sliding strip, and an adsorption block is provided inside the lubrication groove.

[0008] Preferably, the sliding block has a displacement groove inside, and a spring is provided at the top of the displacement groove along its periphery.

[0009] Preferably, a movable rod is slidably connected inside the displacement groove, the surface of the movable rod is disposed inside the spring, and a pressing block is provided on the top of the movable rod and the spring.

[0010] Preferably, a limiting block is provided at the top of one end of the moving rod, and the limiting block is slidably connected to the inside of the displacement groove.

[0011] Preferably, the top of the limiting block and the bottom of the limiting slot are engaged with each other.

[0012] Beneficial effects

[0013] This invention employs a spring, a moving rod, a limiting block, and a pressing block to enable rapid disassembly and installation of the isolator body. By pressing the pressing block, the moving rod compresses the spring, causing the limiting block to disengage from the limiting slot, thus allowing easy sliding of the sliding block to complete disassembly. During installation, after releasing the pressing block, the spring resets, pushing the limiting block back into the limiting slot to ensure a secure connection of the isolator body. This design simplifies operation, improves disassembly and assembly efficiency, and enhances structural reliability and safety through mechanical self-locking, preventing accidental detachment.

[0014] In this invention, the use of a lubrication groove and an adsorption block can form a stable lubrication layer between the sliding block and the sliding strip, reducing frictional resistance and making the sliding of the isolator body smoother. At the same time, it reduces wear and extends service life. The adsorption block can store and slowly release lubricant to ensure long-term effective lubrication, thereby improving the ease of operation of the equipment. Attached Figure Description

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-5 A quick-release structure for a power distribution isolator includes a connecting plate 1. A sliding strip 2 is provided on the surface of the connecting plate 1. A limiting groove 3 is formed at the bottom of the sliding strip 2. A sliding block 4 is slidably connected to the surface of the sliding strip 2. An isolator body 5 is provided on the surface of the sliding block 4. External connecting pieces 6 are provided at both the top and bottom of the connecting plate 1. A threaded opening is formed inside the external connecting piece 6, and an external screw 7 is threaded into the threaded opening. A lubrication groove 8 is formed on the side of the sliding strip 2 away from the connecting plate 1. An adsorption block 9 is provided inside the lubrication groove 8. A displacement groove 10 is formed inside the sliding block 4. A spring 11 is provided along the periphery of the top of the displacement groove 10. A moving rod 12 is slidably connected inside the displacement groove 10. The surface of the moving rod 12 is located inside the spring 11. A pressing block 13 is provided on the top of both the moving rod 12 and the spring 11. A limiting block 14 is provided at the top of one end of the moving rod 12. The limiting block 14 is slidably connected inside the displacement groove 10, and the top of the limiting block 14 and the bottom of the limiting groove 3 are engaged with each other.

[0026] Reference Figure 2 The lubrication groove 8 and the adsorption block 9 are the same size and shape and completely overlap, so that the sliding block 4 will come into contact with the adsorption block 9 during the movement of the sliding strip 2. The adsorption block 9 then adsorbs the lubricating oil, thus lubricating the sliding block 4 and reducing the wear between the sliding strip 2 and the sliding block 4.

[0027] Reference Figure 3 A sliding groove is provided in the middle of the back of the sliding block 4, and it works in conjunction with the sliding strip 2. The bottom of the sliding groove and the other end of the displacement groove 10 are connected to each other, so that the limiting block 14 can move synchronously inside the sliding groove and the displacement groove 10. The moving rod 12 is hook-shaped.

[0028] Reference Figure 4-5Both the limiting slot 3 and the limiting block 14 are triangular in shape and are mutually compatible and overlapping. During the movement of the sliding block 4, the limiting block 14 will continuously contact and extend and retract with multiple sets of limiting slots 3. The spring 11 and the moving rod 12 will also move synchronously and adjust their states as the limiting block 14 moves. Until the sliding block 4 moves to the appropriate position, one set of limiting slots 3 and the limiting block 14 will engage and lock, ensuring the normal use of the isolator body 5. Specific Implementation Example 2:

[0030] A quick-release structure for a power distribution isolator, further based on the basic structure in Specific Embodiment 1, has the following working steps: During installation, the connecting plate 1 is first fixed to the power distribution equipment with external screws 7, and then the sliding block 4 is aligned with the sliding strip 2 and pushed in. The limiting block 14 automatically engages with the limiting slot 3 under the action of the spring 11 to complete the locking. During disassembly, the pressing block 13 is pressed to disengage the limiting block 14 from the limiting slot 3, and the sliding block 4 together with the isolator body 5 can slide out along the sliding strip 2 to achieve quick disassembly.

[0031] Its working principle is as follows: the sliding block 4 forms a mechanical self-lock with the limiting groove 3 of the sliding strip 2 through the internal spring 11 and limiting block 14, ensuring that the isolator body 5 is firmly connected; when the pressing block 13 is pressed down, the spring 11 is compressed and drives the limiting block 14 to disengage from the limiting groove 3, releasing the lock and allowing the sliding block 4 to slide freely. The adsorption block 9 in the lubrication groove 8 continuously provides lubrication, reducing sliding friction, ensuring smooth operation and reducing wear.

[0032] In summary:

[0033] The use of spring 11, moving rod 12, limiting block 14, and pressing block 13 enables quick disassembly and installation of the isolator body 5. By pressing the pressing block 13, the moving rod 12 is driven to compress the spring 11, causing the limiting block 14 to disengage from the limiting slot 3, thus allowing the sliding block 4 to slide easily to complete the disassembly. During installation, after releasing the pressing block 13, the spring 11 returns to its original position and pushes the limiting block 14 back into the limiting slot 3, ensuring a secure connection of the isolator body 5. This design simplifies operation, improves disassembly and assembly efficiency, and enhances the reliability and safety of the structure through mechanical self-locking, preventing accidental detachment.

[0034] The use of lubrication groove 8 and adsorption block 9 can form a stable lubrication layer between sliding block 4 and sliding strip 2, reducing frictional resistance and making the sliding of isolator body 5 smoother. At the same time, it reduces wear and extends service life. Adsorption block 9 can store and slowly release lubricant to ensure long-term effective lubrication, thereby improving the ease of operation of the equipment.
