Description

Technical Field

[0001] This utility model relates to the field of electromagnetic lock technology, specifically a high-voltage switch electromagnetic lock that is easy to disassemble. Background Technology

[0002] High-voltage switches generally refer to electrical appliances with a rated voltage of 3kV and above, mainly used for opening and closing conductive circuits. They are often integrated as high-voltage switchgear. High-voltage switchgear plays a role in power generation, transmission, distribution, power conversion, and consumption, providing functions such as switching, control, and protection. It has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and busbar connections. Due to its high risk, the cabinet door must be locked during normal operation. Traditionally, high-voltage switchgear mostly uses traditional door lock structures, which are opened with a key. With the development of technology, electromagnetic locks have gradually replaced traditional lock cylinder structures to achieve automatic opening and closing of cabinet doors. Electromagnetic locks utilize the principle of electromagnetism. When current passes through silicon steel sheets, it generates a strong attraction force to attract and adsorb iron plates to lock the door. After the access control system correctly identifies the personnel, it cuts off the power, and the electromagnetic lock loses its attraction force, allowing the door to open.

[0003] However, existing high-voltage switch electromagnetic locks still have some problems in use:

[0004] For example, a high-voltage switchgear with an electromagnetic lock structure, as described in application number CN201721465599.1, includes a support frame, which is fixedly installed on a shelf inside the cabinet. A cabinet door is hinged on one side of the lower part of the cabinet, and an electric lock is installed on the cabinet door. A telescopic electromagnet is fixedly installed on the support frame, and a push rod is fixedly installed at the output end of the telescopic electromagnet. One end of the push rod is rotatably connected to a connecting rod, and one end of the connecting rod is rotatably connected to an L-shaped limit rod. A slide rail is provided on one side of the L-shaped limit rod, and a slider is slidably connected on the slide rail. A baffle is provided on the slider, and a sliding plate is provided on the outer surface of the slider. A live indicator is also provided at the upper part of the cabinet. The electric lock and the telescopic electromagnet are both connected to the live indicator. A leakage current sensor is electrically connected to the live indicator, and the leakage current sensor is installed on a cable inside the cabinet.

[0005] In the traditional field of high-voltage switch electromagnetic locks, inaccurate positioning during installation often leads to low installation efficiency, and the installation direction is easily deviated, affecting the stability of the connection. In addition, there is a lack of convenient and effective quick disassembly and assembly structures. Maintenance often requires the use of tools and consumes a lot of time for disassembly, which makes it difficult to meet the requirements of modern power systems for convenient equipment installation and efficient maintenance.

[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0007] To address the aforementioned issues, an innovative design was developed based on the existing high-voltage switch electromagnetic lock. Utility Model Content

[0008] The purpose of this utility model is to provide a high-voltage switch electromagnetic lock that is easy to disassemble, in order to solve the problems mentioned in the background art of high-voltage switch electromagnetic locks, such as inaccurate positioning leading to low installation efficiency, easy deviation of installation direction affecting connection stability, lack of convenient and effective quick disassembly and assembly structure, and the need to use tools and spend a lot of time disassembling during maintenance, which makes it difficult to meet the requirements of modern power systems for convenient equipment installation and efficient maintenance.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A high-voltage switch electromagnetic lock that is easy to disassemble includes a mounting base and a lock body. The lock body is provided on one side of the mounting base. The outer surface of the mounting base has two sets of mating grooves symmetrically formed. A guide post is fixed in the middle of the mating groove. The rear end face of the lock body is fixed with a mating seat. The outer surface of the mating seat has a guide hole adapted to the guide post. The outer surface of the mounting base has a connecting groove. The outer surface of the mounting base has two sets of sliding grooves symmetrically formed. A spring is installed inside the sliding groove. The other end of the spring is fixed with a connecting plate. A locking block is fixed on one side of the connecting plate. The rear end of the lock body is fixed with a connecting block. The outer surface of the connecting block has two sets of locking grooves corresponding to the locking block.

[0011] By adopting the above technical solution, the connecting block is accurately positioned close to the mounting base by the guide pin on the mounting base and the guide hole on the lock body docking seat. At the same time, the spring in the slide groove pushes the connecting plate to drive the locking block into the locking slot of the connecting block to achieve locking. This enables the electromagnetic lock to be installed quickly, accurately and securely connected. Moreover, when disassembling, the lock body can be easily removed by simply squeezing the locking block to make it disengage from the locking slot, which is convenient for maintenance.

[0012] Preferably, each of the two sets of docking grooves is equipped with two sets of guide posts, and the guide holes and guide posts are designed to correspond one-to-one, and the diameter of the guide holes is adapted to the diameter of the guide posts.

[0013] By adopting the above technical solution, and utilizing the design of one-to-one correspondence between guide posts and guide holes with matching hole diameters, the guide posts can be accurately embedded into the guide holes during lock body installation, providing a clear installation path for the lock body, ensuring accurate docking between the lock body and the mounting base, preventing installation misalignment, and enabling subsequent locking blocks and slots to engage smoothly, thereby improving installation efficiency and connection stability.

[0014] Preferably, the docking seat has a U-shaped structure, and the protrusion of the docking seat is in close contact with the inner wall of the docking groove.

[0015] The above technical solution adopts a U-shaped structure for the docking seat, with its protrusion fitting snugly against the inner wall of the docking groove. The shape matching of the two creates a tight contact, and a stable connection is formed through physical limiting. This enhances the connection stability between the lock body and the mounting base, prevents the lock body from shaking or shifting after installation, and ensures the overall reliability of the electromagnetic lock structure.

[0016] Preferably, a limiting shaft is fixed inside the groove, and the middle part of the connecting plate is slidably connected to the outer surface of the limiting shaft.

[0017] By adopting the above technical solution, a limiting shaft is set in the slide groove, and the middle part of the connecting plate is slidably connected to the limiting shaft. The limiting shaft provides a precise track for the movement of the connecting plate, so that it can only slide in a straight line in the axial direction of the limiting shaft. At the same time, the limiting shaft provides physical support for the connecting plate, preventing the connecting plate from shifting or shaking under the action of spring force or other external forces. This ensures the accuracy and stability of the connecting plate when it drives the locking block to move, and ensures that the locking block can accurately engage or disengage from the slot. This makes the installation and disassembly process of the electromagnetic lock smoother and more reliable, and avoids the locking block from not engaging properly with the slot due to the movement deviation of the connecting plate, which would affect the normal use and connection stability of the electromagnetic lock.

[0018] Preferably, a tie rod is fixed to the outer side of the connecting plate, and the tie rod has an L-shaped structure.

[0019] By adopting the above technical solution, an L-shaped pull rod is set on the outside of the connecting plate. Utilizing the lever principle, when an external force is applied to the L-shaped pull rod, the force can be effectively transmitted to the connecting plate, causing the connecting plate to move. This allows the operator to manually pull the connecting plate, causing the locking block to disengage from the slot, thus achieving rapid disassembly of the electromagnetic lock and improving operational convenience and maintenance efficiency.

[0020] Preferably, the mounting base has four sets of mounting holes symmetrically opened at both ends, and the mounting holes adopt a horizontally designed elongated waist-shaped structure.

[0021] By adopting the above technical solution, the horizontally adjustable space of the mounting holes in the elongated waist structure allows the mounting base to be finely adjusted in the horizontal direction to adapt to different installation scenarios and slight deviations in the mounting surface. This improves the flexibility and versatility of the mounting base installation, making it easier to install the electromagnetic lock in the appropriate position, ensuring installation accuracy, and reducing installation difficulties caused by uneven or inaccurate mounting surfaces.

[0022] Compared with the prior art, the beneficial effects of this utility model are: this easily disassembled high-voltage switch electromagnetic lock...

[0023] 1. Two sets of symmetrical mating grooves on the mounting base mate with the U-shaped mating seat at the rear of the lock body. The protruding part of the mating seat fits snugly against the inner wall of the mating groove, which can initially and accurately position and limit the installation direction of the lock body, preventing lateral swaying. Two sets of guide pins in each mating groove mate with the guide holes on the mating seat, providing a precise path for the lock body during installation, ensuring accurate installation and greatly improving installation efficiency and accuracy. At the same time, it makes the overall connection of the electromagnetic lock stable and reliable, providing a strong guarantee for convenient disassembly and efficient maintenance in the future, effectively improving the user experience and practicality of the equipment.

[0024] 2. The initial positioning and engagement between the connecting groove on the mounting base and the connecting block at the rear end of the lock body is achieved. The spring within the groove, in its natural state, pushes the connecting plate along the limiting shaft, causing the locking block to extend and precisely embed into the connecting block's slot, forming a stable mechanical lock and ensuring reliable electromagnetic lock connection. During disassembly, pulling the L-shaped lever compresses the connecting plate's spring, disengaging the locking block from the slot, enabling tool-free quick assembly and disassembly. The limiting shaft effectively constrains the connecting plate's sliding trajectory, preventing the locking block from shifting, ensuring structural stability, and significantly improving the installation efficiency, maintenance convenience, and reliability of the high-voltage switch electromagnetic lock.

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figures 1-3 This utility model provides a technical solution:

[0033] The easily disassembled high-voltage switch electromagnetic lock includes a mounting base 1 and a lock body 3. The lock body 3 is located on one side of the mounting base 1. Two sets of mating grooves 4 are symmetrically formed on the outer surface of the mounting base 1. A guide post 5 is fixed in the middle of the mating groove 4. A mating seat 6 is fixed to the rear end face of the lock body 3. Guide holes 7, adapted to the guide posts 5, are formed on the outer surface of the mating seat 6. Two sets of guide posts 5 are installed inside each of the two sets of mating grooves 4, and the guide holes 7 correspond one-to-one with the guide posts 5, with the diameter of the guide holes 7 matching the diameter of the guide posts 5. The mating seat 6 has a U-shaped structure, and the protrusion of the mating seat 6 is in close contact with the inner wall of the mating groove 4.

[0034] This easily disassembled high-voltage switch electromagnetic lock, during installation, uses two sets of mating grooves 4 on the mounting base 1 to provide positioning space for the mating seat 6 on the rear end face of the lock body 3. Since the mating seat 6 has a U-shaped structure and its protrusion is closely connected to the inner wall of the mating groove 4, it can initially restrict the installation direction of the lock body 3 and prevent it from swaying left and right. At the same time, the two sets of guide posts 5 installed inside each set of mating grooves 4 cooperate with the guide holes 7 on the outer surface of the mating seat 6 that correspond one-to-one with the guide posts 5 and have a suitable diameter. When the lock body 3 is installed onto the mounting base 1, the guide posts 5 can be accurately embedded into the guide holes 7, providing a precise installation path for the lock body 3. This ensures that the lock body 3 is accurately installed onto the mounting base 1, greatly improving installation efficiency and accuracy, making the overall connection of the electromagnetic lock more stable and reliable, and facilitating subsequent disassembly and maintenance operations.

[0035] Example 2

[0036] Please see Figures 2-4 This utility model provides a technical solution:

[0037] The outer surface of the mounting base 1 has a connecting groove 8, and two sets of sliding grooves 9 are symmetrically formed on the outer surface of the mounting base 1. A spring 11 is installed inside the sliding groove 9, and a connecting plate 12 is fixed to the other end of the spring 11. A locking block 13 is fixed to one side of the connecting plate 12, and a connecting block 15 is fixed to the rear end of the lock body 3. The outer surface of the connecting block 15 has two sets of locking grooves 16 corresponding to the locking block 13. A limiting shaft 10 is fixed inside the sliding groove 9, and the middle part of the connecting plate 12 is slidably connected to the outer surface of the limiting shaft 10. A pull rod 14 is fixed to the outer side of the connecting plate 12, and the pull rod 14 has an L-shaped structure. Four sets of mounting holes 2 are symmetrically formed at both ends of the mounting base 1, and the mounting holes 2 adopt a transversely designed elongated structure.

[0038] This easily disassembled high-voltage switch electromagnetic lock features four sets of transverse elongated mounting holes 2 symmetrically opened at both ends of the mounting base 1, allowing for flexible adjustment of the installation position according to the actual installation environment. The connecting groove 8 on its outer surface is used for initial positioning and engagement with the lock body 3. Simultaneously, two sets of symmetrically distributed sliding grooves 9 constrain the sliding trajectory of the connecting plate 12 via a limiting shaft 10. When the spring 11 is in its natural state, its elastic force pushes the connecting plate 12 outward along the limiting shaft 10, causing the locking block 13 fixed to one side of the connecting plate 12 to extend out of the sliding groove 9. When the connecting block 15 at the rear end of the lock body 3... When inserted into the connecting slot 8, the locking block 13 is compressed by the spring 11 and retracts into the slide groove 9. When the slot 16 of the connecting block 15 moves to the position corresponding to the locking block 13, the spring 11 resets and pushes the locking block 13 into the slot 16 to form a mechanical lock. If it is necessary to disassemble the lock body 3, the connecting plate 12 can be compressed by pulling the L-shaped pull rod 14, so that the locking block 13 can be released from the slot 16. This structure enables tool-free quick disassembly and assembly through the elastic force of the spring 11. The limiting shaft 10 ensures the stability of the movement of the connecting plate 12, and the elongated mounting hole 2 improves the adaptability of the equipment.

[0039] Working principle:

[0040] During installation, the four sets of horizontally elongated mounting holes 2 at both ends of the mounting base 1 can be flexibly adjusted to adapt to different installation position requirements. When the connecting block 15 at the rear end of the lock body 3 is inserted into the connecting groove 8 of the mounting base 1, the spring 11 initially pushes the connecting plate 12 along the limiting shaft 10 in the symmetrically distributed sliding groove 9, causing the locking block 13 to extend. The connecting block 15 squeezes the locking block 13, causing it to compress the spring 11 and retract into the sliding groove 9. When the locking groove 16 corresponds to the locking block 13, the spring 11 resets, causing the locking block 13 to be embedded in the locking groove 16 and locked. During disassembly, pulling the L-shaped pull rod 14 drives the connecting plate 12 to compress the spring 11, allowing the locking block 13 to disengage from the locking groove 16. The entire system achieves convenient disassembly and stable connection through the elasticity of the spring 11, the guidance of the limiting shaft 10, and the design of the elongated holes.
