Description

Technical Field

[0001] This utility model relates to the field of high voltage power distribution equipment technology, and in particular to a portable and detachable operation panel for a high voltage power distribution control cabinet. Background Technology

[0002] In high-voltage power distribution systems, the high-voltage power distribution control cabinet is one of the core pieces of equipment. Its control panel, as a key component for human-machine interaction, requires frequent operation or disassembly and reassembly during equipment maintenance and troubleshooting. Currently, most high-voltage power distribution control cabinet control panels on the market are installed on the cabinet door using bolts or snap-fit ​​connections. Bolt fixing requires tools such as screwdrivers for disassembly and reassembly, making the process cumbersome, especially in scenarios with high maintenance frequency. Repeated disassembly and reassembly not only consumes a lot of time but also easily leads to wear on the bolt hole threads, affecting the stability of subsequent installations. While snap-fit ​​connections do not require tools, they are prone to breakage due to excessive force during disassembly and reassembly. Furthermore, the lack of a precise positioning structure during installation can easily lead to misalignment between the control panel and the cabinet door's through-hole, resulting in an uneven surface on the panel after installation. This affects aesthetics and may allow dust and moisture to enter through gaps, affecting the normal operation of internal components. In addition, during the sliding disassembly and assembly of traditional control panels, friction between the guide block and the guide groove can easily cause wear and tear, shortening the service life of the components. Furthermore, some control panels do not have anti-static structures, which can easily generate static electricity in dry environments, potentially interfering with the precision components of high-voltage power distribution equipment and posing a safety hazard. Utility Model Content

[0003] To address the problems of inconvenient disassembly and assembly (requiring tools or easily damaged clips), inaccurate installation and positioning, easy wear of sliding parts, lack of anti-static protection, and susceptibility of springs to impurities in existing high-voltage power distribution control cabinet operation panels, this utility model provides a convenient disassembly and assembly operation panel for high-voltage power distribution control cabinets.

[0004] This utility model discloses a detachable operating panel for a high-voltage power distribution control cabinet, comprising a cabinet body and a cabinet door connected by hinges. The cabinet door has a rectangular through-hole, and the operating panel is mounted on the door via a detachable mechanism. The detachable mechanism includes a pair of U-shaped guide grooves fixed to the cabinet door and a pair of guide blocks fixed to the operating panel. Limiting components are provided on the guide blocks, and limiting holes are provided on the U-shaped guide grooves. Each limiting component includes a sliding cavity on the guide block, with a sliding plate slidably connected inside the cavity. One end of the sliding plate is fixed with a limiting head that matches the limiting hole, and a spring is installed inside the sliding cavity on the other side of the sliding plate.

[0005] The end of the limiting head away from the slide plate is designed as a hemispherical structure, the diameter of which matches the inner diameter of the limiting hole, and the arc surface of the hemispherical structure faces the side away from the slide plate. Wear-resistant pads are attached to the inner wall of the U-shaped guide groove. The wear-resistant pads are made of polytetrafluoroethylene and come into contact with the wear-resistant pads when the guide block slides. The edge of the operating panel away from the cabinet door has an arc-shaped chamfer with a radius of 2-5mm, and the outer surface of the operating panel is coated with an anti-static coating. The operating panel is adapted to the rectangular through hole, and the outer surface of the operating panel passes through the rectangular through hole and is flush with the outer surface of the cabinet door. The spring is a cylindrical helical compression spring, and a telescopic protective sleeve is fitted on the outside of the spring. One end of the telescopic protective sleeve is fixedly connected to the slide plate, and the other end is fixedly connected to the cavity wall of the slide cavity away from the limiting head. Several positioning protrusions are provided around the rectangular through hole on the cabinet door. The side of the operating panel near the cabinet door has positioning grooves that correspond to the positioning protrusions one by one. When the operating panel is installed in place, the positioning protrusions are embedded in the positioning grooves.

[0006] Installation Process: First, align the guide block on the control panel with the U-shaped guide groove on the cabinet door, then push the control panel towards the cabinet door. During this pushing process, the guide block slides along the U-shaped guide groove. The hemispherical arc surface of the limiting head first contacts the inner wall of the U-shaped guide groove. After being compressed, it generates a force towards the inside of the sliding cavity. This force pushes the sliding plate along the inner wall of the sliding cavity and compresses the spring inside the sliding cavity. At this time, the limiting head gradually retracts into the sliding cavity to avoid obstructing the sliding of the guide block. Continue pushing the control panel until the positioning groove on the side of the control panel near the cabinet door aligns with the positioning protrusion on the cabinet door. At this point, the guide block has just slid to the end of the U-shaped guide groove, and the limiting component on the guide block is completely aligned with the limiting hole on the U-shaped guide groove. After the spring loses its compressive force, it resets along its own axis, pushing the sliding plate towards the limiting hole. The sliding plate drives the limiting head out of the sliding cavity and finally embeds it into the limiting hole. At the same time, the positioning protrusion is completely embedded in the positioning groove, completing the installation of the control panel. After installation, the outer surface of the control panel is flush with the outer surface of the cabinet door.

[0007] Disassembly process: When it is necessary to disassemble the control panel, press the limiting head towards the inside of the slide cavity. After the limiting head is under force, it pushes the slide plate to compress the spring until the limiting head completely disengages from the limiting hole and retracts into the slide cavity. At this time, pull the control panel away from the cabinet door. The control panel drives the guide block to slide along the U-shaped guide groove. The positioning protrusion gradually disengages from the positioning groove. Continue to pull the control panel until the guide block completely disengages from the U-shaped guide groove, completing the disassembly of the control panel.

[0008] Throughout the entire disassembly, assembly, and use process, the PTFE wear-resistant pads on the inner wall of the U-shaped guide channel can reduce frictional loss during the sliding of the guide block and extend the service life of the guide block and the U-shaped guide channel; the anti-static coating on the outer surface of the operating panel can effectively prevent the generation of static electricity and avoid interference from static electricity to the internal components of the high-voltage power distribution equipment; the telescopic protective sleeve on the outside of the spring can extend and retract synchronously with the sliding plate to prevent dust, moisture, and other impurities from entering the sliding cavity, avoid the spring from rusting or jamming due to the adhesion of impurities, and ensure the stability of the spring's elastic performance.

[0009] Beneficial effects

[0010] Easy and efficient disassembly and assembly: The control panel can be disassembled and assembled without tools through the easy disassembly mechanism. During installation, simply push the panel to make the limit head engage with the limit hole. During disassembly, simply press the limit head to pull the panel. No screwdriver or other tools are needed, which greatly shortens the disassembly and assembly time and improves maintenance efficiency. It is especially suitable for high-frequency maintenance scenarios.

[0011] Precise installation and positioning: The positioning protrusions on the cabinet door cooperate with the positioning grooves on the control panel to quickly align the control panel with the cabinet door during installation, avoiding panel misalignment. At the same time, the cooperation between the limiting component and the U-shaped guide groove can further fix the panel position, ensuring that the panel is stable and flush with the cabinet door after installation, improving the overall aesthetics of the equipment.

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.

[0021] like Figure 1-5 As shown;

[0022] A portable and detachable operating panel for a high-voltage power distribution control cabinet.

[0023] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "Currently, the operating panels of high-voltage power distribution control cabinets on the market are mostly installed on the cabinet door using bolt fixing or snap-fit ​​rigid connections. When bolt fixing is used, disassembly and assembly require tools such as screwdrivers, which is cumbersome. Especially in scenarios with high maintenance frequency, repeated disassembly and assembly not only consumes a lot of time but also easily leads to wear of the bolt hole threads, affecting the stability of subsequent installation. When using snap-fit ​​rigid connections, although no tools are required, the snaps are prone to breakage due to excessive force during disassembly and assembly, and the lack of a precise positioning structure during installation easily leads to misalignment between the operating panel and the through hole of the cabinet door." Furthermore, the uneven surface of the panel after installation not only affects aesthetics but also allows dust and moisture to enter through gaps, affecting the normal operation of internal components. In addition, during the sliding and disassembly process of traditional control panels, friction between the guide blocks and guide grooves easily causes wear and tear, shortening the lifespan of components. Moreover, some control panels lack anti-static structures, making them prone to generating static electricity in dry environments, which may interfere with the precision components of high-voltage power distribution equipment, posing a safety hazard. Considering practical use, this problem is clearly a real and difficult-to-solve issue. Therefore, to address this technical problem, a portable and detachable control panel for high-voltage power distribution control cabinets is provided.

[0024] Example 1

[0025] like Figure 1-5 As shown in the figure;

[0026] The high-voltage power distribution control cabinet of this embodiment has a detachable operation panel, which includes a cabinet body 1 and a cabinet door 2. The cabinet body 1 and the cabinet door 2 are connected by a hinge 3. A rectangular through hole 4 is provided on the cabinet door 2. The operation panel 6 is installed on the cabinet door 2 through a detachable mechanism 5.

[0027] The easy-to-disassemble mechanism 5 includes a pair of U-shaped guide channels 51 fixed on the cabinet door 2 and a pair of guide blocks 52 fixed on the operation panel 6. The guide blocks 52 are provided with limit components 53, and the U-shaped guide channels 51 are provided with limit holes 54. The limit component 53 includes a sliding cavity 531 opened on the guide block 52. A sliding plate 532 is slidably connected inside the sliding cavity 531. One end of the sliding plate 532 is fixed with a limit head 533 that matches the limit hole 54. A spring 534 is provided inside the sliding cavity 531 on the other side of the sliding plate 532.

[0028] The end of the limiting head 533 away from the slide plate 532 is designed as a hemispherical structure. The diameter of the hemispherical structure is adapted to the inner diameter of the limiting hole 54, and the arc surface of the hemispherical structure faces the side away from the slide plate 532. This design makes it easier for the limiting head 533 to be squeezed and compressed back to the sliding cavity 531 when the guide block 52 slides, thus reducing sliding resistance.

[0029] Wear-resistant pads are attached to the inner wall of the U-shaped guide groove 51. The wear-resistant pads are made of polytetrafluoroethylene (PTFE). When the guide block 52 slides, it comes into contact with the wear-resistant pads. The PTFE wear-resistant pads are not only highly wear-resistant, but also have self-lubricating properties, which can effectively reduce the coefficient of friction between the guide block 52 and the U-shaped guide groove 51 and reduce component wear.

[0030] The control panel 6 has a rounded chamfer on the edge away from the cabinet door 2. The radius of the rounded chamfer is 3mm (preferably within the range of 2-5mm). The rounded chamfer can prevent operators from being scratched by sharp edges during operation or disassembly. The outer surface of the control panel 6 is coated with an anti-static coating. The anti-static coating is made of epoxy anti-static paint, which can effectively prevent the generation of static electricity and avoid static electricity from interfering with the internal components of the high-voltage power distribution equipment.

[0031] The control panel 6 is adapted to the rectangular through hole 4. The outer surface of the control panel 6 passes through the rectangular through hole 4 and is flush with the outer surface of the cabinet door 2. This design can ensure the flatness of the surface of the cabinet door 2 and reduce the risk of dust and moisture entering the cabinet 1 through gaps.

[0032] Spring 534 is a cylindrical helical compression spring. A telescopic protective sleeve is fitted on the outside of spring 534. The telescopic protective sleeve is made of rubber. One end of the telescopic protective sleeve is fixedly connected to slide plate 532, and the other end is fixedly connected to the cavity wall of slide cavity 531 away from limit head 533. The telescopic protective sleeve can extend and retract synchronously with the sliding of slide plate 532, effectively preventing dust, water vapor and other impurities from entering the interior of slide cavity 531, and avoiding rust or jamming of spring 534.

[0033] Four positioning protrusions are provided around the rectangular through hole 4 on the cabinet door 2 (evenly distributed at the four corners of the rectangular through hole 4). The side of the operation panel 6 near the cabinet door 2 has positioning grooves that correspond one-to-one with the positioning protrusions. When the operation panel 6 is installed in place, the positioning protrusions are embedded in the positioning grooves. The cooperation between the positioning protrusions and the positioning grooves can realize the quick positioning of the operation panel 6 and avoid misalignment during installation.

[0034] The installation steps for the portable and detachable operation panel of the high-voltage power distribution control cabinet in this embodiment are as follows:

[0035] The operator holds the control panel 6 and aligns the guide block 52 on the control panel 6 with the U-shaped guide groove 51 on the cabinet door 2 to ensure that the sliding direction of the guide block 52 is consistent with the extension direction of the U-shaped guide groove 51.

[0036] Slowly push the operation panel 6 towards the cabinet door 2. The guide block 52 slides along the wear-resistant pad inside the U-shaped guide groove 51. At this time, the hemispherical arc surface of the limiting head 533 contacts and is squeezed against the inner wall of the U-shaped guide groove 51. The limiting head 533 pushes the slide plate 532 to slide along the inner wall of the slide cavity 531 into the slide cavity 531. The slide plate 532 compresses the spring 534, and the limiting head 533 gradually retracts into the slide cavity 531.

[0037] Continue pushing the operation panel 6 until the positioning groove on the side of the operation panel 6 near the cabinet door 2 is aligned with the positioning protrusion on the cabinet door 2. At this time, the guide block 52 slides to the end of the U-shaped guide groove 51, and the limiting hole 54 on the guide block 52 is aligned with the limiting component 53.

[0038] The spring 534 resets under its own elastic force, pushing the slide plate 532 to slide closer to the limiting hole 54. The slide plate 532 drives the limiting head 533 to extend out of the slide cavity 531 and embed into the limiting hole 54. At the same time, the positioning protrusion is fully embedded in the positioning groove. The outer surface of the operation panel 6 is flush with the outer surface of the cabinet door 2, completing the installation.

[0039] The disassembly steps are as follows:

[0040] The operator presses the limiting head 533 with his finger towards the inside of the slide cavity 531. After the limiting head 533 is subjected to force, it pushes the slide plate 532 to compress the spring 534 until the limiting head 533 completely disengages from the limiting hole 54 and retracts into the slide cavity 531.

[0041] Slowly pull the operation panel 6 away from the cabinet door 2. The operation panel 6 drives the guide block 52 to slide along the U-shaped guide groove 51, and the positioning protrusion gradually disengages from the positioning groove.

[0042] Continue pulling the control panel 6 until the guide block 52 is completely disengaged from the U-shaped guide groove 51. The control panel 6 is then removed from the rectangular through hole 4 of the cabinet door 2, completing the disassembly.

[0043] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
