Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to an electrical cabinet that is easy to maintain. Background Technology

[0002] Electrical cabinets are widely used in various fields such as industrial production, commercial buildings, and residential housing to house and protect various electrical equipment, switches, cables, and other components, ensuring the safe and stable operation of electrical systems. Currently, common electrical cabinets present a problem of inconvenient maintenance in practical use. Electrical cabinets typically house a large number of electrical components, and when maintenance is required on a particular component, the limitations of the cabinet's structural design often make it difficult to quickly and easily access the target component.

[0003] Furthermore, electrical components are typically fixed inside the cabinet, making disassembly and installation cumbersome, requiring various tools and consuming significant time and effort. This not only increases maintenance costs but can also disrupt normal production or daily life due to prolonged power outages for maintenance. In locations with high requirements for equipment continuity, such as factory production lines and data centers, the extended downtime caused by inconvenient electrical cabinet maintenance can result in substantial economic losses.

[0004] Therefore, an electrical cabinet that is easy to inspect and maintain is invented to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical cabinet that is easy to maintain. Through innovative design of the cabinet structure and internal components, it solves the problem of inconvenient maintenance of existing electrical cabinets, enabling operators to perform maintenance on electrical components inside the cabinet more easily and efficiently, reducing maintenance time and costs, and improving the reliability and stability of equipment operation.

[0006] This application provides an electrical cabinet that is easy to maintain, and adopts the following technical solution: it includes a cabinet body with a double-opening structure. The left and right sides of the cabinet body are respectively provided with cabinet doors and are hinged to the cabinet body. A locking component is provided between the cabinet doors and the cabinet body. When the cabinet doors are opened to 90 degrees or 180 degrees, the locking component locks the cabinet doors. A quick-release component is provided inside the cabinet body, and electrical components are provided on the quick-release component.

[0007] Optionally, the quick-release assembly includes multiple layers of guide rails arranged inside the cabinet, and a mounting bracket slidably arranged on the guide rails. The mounting bracket has a groove, and slots are formed on both sides of the groove. A sliding seat is provided in the groove, and a mounting hole is formed on the sliding seat. A sliding block that can be inserted into the slot is provided on the sliding seat. A fixing spring is provided between the sliding block and the sliding seat, and a push plate is provided on the sliding block.

[0008] Optionally, the mounting bracket is provided with rollers on both sides, and the rollers are in rolling cooperation with the guide rail.

[0009] Optionally, the locking assembly includes a movable arm, a fixed base, a rotating shaft, a locking element, and a spring; the movable arm is used to connect with the cabinet door, the fixed base is used to connect with the cabinet body, and the movable arm and the fixed base are hinged by the rotating shaft; the movable arm is provided with multiple arc-shaped slots, and the fixed base is provided with a guide groove for the locking element to slide; one end of the locking element is adapted to be inserted into the arc-shaped slot, and the other end is connected to the spring; the spring is used to drive the locking element to be inserted into the arc-shaped slot to restrict the movable arm from rotating around the rotating shaft; under the action of external force, the locking element can compress the spring and disengage from the arc-shaped slot to unlock.

[0010] Optionally, the number of arc-shaped slots is three, distributed along the trajectory of the movable arm rotating around the pivot, so as to lock the cabinet door at three angular positions: 0 degrees, 90 degrees, and 180 degrees.

[0011] Optionally, the locking element can be inserted into the arc-shaped slot, with one end of the spring abutting against the fixing seat and the other end abutting against the locking element.

[0012] In summary, this application includes the following beneficial technical effects: 1. When the cabinet door is opened to 90 degrees or 180 degrees, the locking mechanism locks the door in place. This design ensures the cabinet door remains stable when open, preventing it from wobbling. This guarantees operator safety and provides a stable working environment for maintenance. For example, when the cabinet door is opened to 180 degrees, the entire interior is fully exposed, allowing operators to inspect electrical components without obstruction, greatly improving the convenience of maintenance. 2. The quick-release assembly includes multi-layered guide rails installed inside the cabinet and mounting brackets that slide on the guide rails. The multi-layered guide rail design makes full use of the internal space of the cabinet and allows for the rational layering of electrical components. At the same time, the mounting brackets can slide along the guide rails, making it easy to slide the entire mounting bracket containing electrical components out of the cabinet, bringing the electrical components closer to the operator for easy inspection, maintenance, or replacement. 3. The mounting bracket has slots on both sides of the groove. A sliding block on the sliding seat within the groove can be inserted into the slot, and a retaining spring is installed between the sliding block and the sliding seat. A push plate is also provided on the sliding block. This structure allows electrical components to be quickly secured on the sliding seat through the cooperation of the sliding block and the slot. When it is necessary to remove the electrical component, simply push the push plate to compress the retaining spring, causing the sliding block to disengage from the slot, allowing the sliding seat to be removed from the groove. This enables quick and easy removal of the electrical component, greatly improving maintenance efficiency. Attached Figure Description

[0014] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model.

[0015] Reference Figure 1 , Figure 4 One embodiment is shown where the cabinet body 1 is rectangular in shape, and the cabinet doors 2 on the left and right sides are sized to fit the sides of the cabinet body 1. Hinges connect the cabinet doors 2 to the cabinet body 1 along its left and right edges. One side of the hinge is fixed to the side of the cabinet body 1, and the other side is fixed to the edge of the cabinet door 2, allowing the cabinet door 2 to rotate around the hinge pivot. In this embodiment, a locking assembly 3 is installed near the connection point between the cabinet body 1 and the cabinet door 2.

[0016] The implementation principle of the above embodiment is as follows: When the electrical cabinet needs to be opened, the operator applies force to push the cabinet door 2, causing the door 2 to rotate around the hinge axis. As the door 2 rotates, the locking component 3 begins to work. When the door 2 rotates to 90 degrees or 180 degrees, the corresponding structures in the locking component 3 cooperate to lock the door 2, keeping it in the open position, facilitating the operator to perform maintenance and other operations on the electrical components inside the cabinet. Compared with the traditional single-door design, this double-door structure greatly increases the operating space, while the locking component 3 ensures the stability of the door 2 in the open state.

[0017] Reference Figure 1 , Figure 2 One embodiment shown is as follows: Inside the cabinet 1, multiple layers of guide rails 5 are distributed in parallel. The guide rails 5 are tightly fixed to the inner walls of the left and right sides of the cabinet 1 by bolts or other fasteners to ensure the stability of the guide rails 5. Slider blocks adapted to the guide rails 5 are provided on both sides of the mounting bracket 6. The sliders are embedded in the guide rails 5, allowing the mounting bracket 6 to slide along the guide rails 5. A groove 7 is opened on the mounting bracket 6 along its length. The slots 8 on both sides of the groove 7 are elongated and parallel to the groove 7. A sliding seat 9 is located within the groove 7, its shape matching the groove 7, allowing it to slide smoothly within the groove 7. A sliding block 11 is mounted on both sides of the sliding seat 9 by a fixing spring 12. One end of the fixing spring 12 is fixed to the sliding seat 9, and the other end is connected to the sliding block 11. A push plate 13 is installed on the end of the sliding block 11 near the outer side of the mounting bracket 6 for easy operation by the operator.

[0018] The implementation principle of the above embodiment is as follows: When electrical components need to be repaired, the mounting bracket 6 is first slid out of the cabinet 1 along the guide rail 5 for easy operation. Then, the operator pushes the push plate 13, which causes the sliding block 11 to compress the fixing spring 12, causing the sliding block 11 to disengage from the slot 8. At this time, the sliding seat 9 can be removed from the channel 7 for repair of the electrical components installed on the sliding seat 9. After the repair is completed, the sliding seat 9 is placed back into the channel 7. The sliding block 11 automatically engages with the slot 8 under the action of the fixing spring 12, achieving quick fixation of the sliding seat 9. Then, the mounting bracket 6 is pushed back into the cabinet 1. The multi-layer guide rail 5 can make full use of the space in the cabinet 1, and the entire quick-release assembly 4 facilitates the installation and removal of electrical components, improving repair efficiency.

[0019] Reference Figure 1 , Figure 2 , Figure 3 One embodiment is shown where mounting seats are provided at the bottom of both sides of the mounting frame 6. The two ends of the axle are mounted in the mounting seats via bearings, and rollers 14 are fitted onto the axles. The surface of the guide rail 5 is smooth and contacts the outer circumferential surface of the rollers 14. In this embodiment, the number of rollers 14 is reasonably set according to the length of the mounting frame 6 to ensure the stability of the mounting frame 6 when sliding on the guide rail 5.

[0020] The implementation principle of the above embodiment is as follows: when the mounting bracket 6 is pushed to slide along the guide rail 5, the roller 14 rolls on the guide rail 5. Since the roller 14 and the guide rail 5 have rolling friction, compared with sliding friction, the friction force is greatly reduced, making it easier and smoother for the operator to push the mounting bracket 6, reducing labor intensity, and facilitating the quick sliding or pushing of the mounting bracket 6 with electrical components from the cabinet 1, further improving the convenience of maintenance.

[0021] Reference Figure 3 , Figure 5 One embodiment is shown as follows: The movable arm 15 is elongated, with one end securely fixed to the edge of the cabinet door 2 by connecting bolts. The fixed base 16 is a block structure, firmly installed on the side of the cabinet body 1 by mounting bolts, corresponding to the movable arm 15. The pivot 17 passes through the corresponding hinge holes on the movable arm 15 and the fixed base 16, allowing the movable arm 15 to rotate relative to the fixed base 16 around the pivot 17. Multiple arc-shaped slots 20 are evenly distributed on the movable arm 15, with their centers coinciding with the axis of the pivot 17. The guide groove on the fixed base 16 is formed along the movement trajectory of the locking member 18 when the movable arm 15 rotates. The locking member 18 is columnar, with one end located within the guide groove and able to slide within it, and the other end able to engage with the arc-shaped slot 20. The spring 19 is installed within the guide groove, with one end abutting against the bottom of the guide groove and the other end in contact with the locking member 18.

[0022] The implementation principle of the above embodiment is as follows: When the cabinet door 2 is closed, the locking member 18, under the action of the spring 19, engages with the arc-shaped groove 20 corresponding to the 0-degree position on the movable arm 15, restricting the rotation of the movable arm 15, thereby keeping the cabinet door 2 closed. When the cabinet door 2 is opened, the cabinet door 2 drives the movable arm 15 to rotate around the pivot 17. The movable arm 15 presses the locking member 18, causing it to overcome the elastic force of the spring 19 and gradually disengage from the original arc-shaped groove 20. When the cabinet door 2 rotates to 90 degrees or 180 degrees, the locking member 18, under the action of the spring 19, engages with the arc-shaped groove 20 at the corresponding position, thereby locking the cabinet door 2. When it is necessary to close the cabinet door 2, force is applied again to compress the spring 19 and disengage from the current arc-shaped groove 20, and the cabinet door 2 can be closed. This locking assembly 3 can fix the cabinet door 2 at a suitable angle according to actual needs, facilitating maintenance operations.

[0023] Reference Figure 5 One embodiment is shown where three arc-shaped slots 20 on the movable arm 15 are located at positions corresponding to 0 degrees, 90 degrees, and 180 degrees, respectively. When the cabinet door 2 is closed, i.e., at the 0-degree position, the locking member 18 engages with the first arc-shaped slot 20; when the cabinet door 2 is opened to 90 degrees, the locking member 18 engages with the second arc-shaped slot 20; and when the cabinet door 2 continues to open to 180 degrees, the locking member 18 engages with the third arc-shaped slot 20. The depth and shape of the three arc-shaped slots 20 are adapted to the end of the locking member 18, ensuring that the locking member 18 can be stably engaged.

[0024] The implementation principle of the above embodiment is as follows: During the rotation of the cabinet door 2, as the movable arm 15 rotates around the pivot 17, the locking member 18 engages with the arc-shaped slots 20 at different positions in sequence. At the 0-degree position, the locking member 18 engages with the corresponding arc-shaped slot 20, keeping the cabinet door 2 closed; at the 90-degree and 180-degree positions, the locking member 18 engages with the corresponding arc-shaped slots 20 respectively, locking the cabinet door 2 at these two angles, providing different levels of operating space for the operator, meeting the needs of various maintenance scenarios, and the locking at the three angle positions is practical and common, making it convenient for operators to use.

[0025] Reference Figure 1 , Figure 5 One embodiment is shown where, within the guide groove of the fixed base 16, one end of the spring 19 abuts tightly against a fixed stop at the bottom of the guide groove. The fixed stop and the fixed base 16 are integrally formed or fixedly connected by welding or other means. One end of the locking member 18 is located within the guide groove, contacting the other end of the spring 19, and the shape of the end of the locking member 18 matches the arc-shaped slot 20, allowing it to be smoothly inserted into the arc-shaped slot 20.

[0026] The implementation principle of the above embodiment is as follows: During the rotation of the cabinet door 2, the movable arm 15 exerts a force on the locking member 18. After being squeezed, the locking member 18 moves into the guide groove, compressing the spring 19. When the cabinet door 2 rotates to a specific angle, that is, when the arc-shaped slot 20 is aligned with the locking member 18, the elastic force of the spring 19 pushes the locking member 18 into the arc-shaped slot 20, thereby restricting the rotation of the movable arm 15 and locking the cabinet door 2. When unlocking is required, an external force is applied to the locking member 18, causing it to compress the spring 19 again and disengage from the arc-shaped slot 20, facilitating the opening and closing operation of the cabinet door 2. This structure is simple and effectively realizes the locking and unlocking functions of the cabinet door 2.

[0027] The working principle of this device is as follows: When cabinet door 2 is opened, cabinet door 2 rotates around the hinge point. The movable arm 15 in the locking assembly 3 rotates with cabinet door 2, squeezing the locking element 18 and compressing the spring 19. When cabinet door 2 reaches 90 degrees or 180 degrees, the locking element 18, under the action of the spring 19, engages with the corresponding arc-shaped slot 20 to achieve locking. During maintenance, the mounting bracket 6 is slid out along the guide rail 5. Because its two side rollers 14 roll in cooperation with the guide rail 5, sliding is more effortless. Pushing the push plate 13 causes the sliding block 11 to compress the fixing spring 12 and disengage from the slot 8. The sliding seat 9 with electrical components is then removed for maintenance. After maintenance, the sliding seat 9 is returned to the channel 7, and the sliding block 11 automatically engages with the slot 8 for fixation. Then, the mounting bracket 6 is pushed back into the cabinet body 1. When cabinet door 2 is closed, the locking element 18 disengages from the slot 8.

[0028] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
