Abstract
Description
Technical Field
[0001] This utility model applies to the field of power distribution cabinet technology and provides a high and low voltage power distribution cabinet. Background Technology
[0002] High-voltage and low-voltage switchgear are crucial equipment in power systems, primarily used for power distribution, control, and protection. High-voltage switchgear is typically used in high-voltage power systems for power distribution and control, while low-voltage switchgear is mostly used in low-voltage power systems, responsible for power distribution, protection, and control of downstream equipment operation. Switchgear usually integrates multiple electrical components, such as circuit breakers, contactors, and relays, providing protection, control, and measurement functions to ensure the safe and stable operation of the power system. Due to their widespread application in industry, construction, and energy sectors, high-voltage and low-voltage switchgear play a vital role in modern power systems.
[0003] In current high and low voltage switchgear applications, a swing door design is typically used for commissioning, installation, and maintenance of the equipment inside. This design allows personnel to enter the cabinet by opening the door to perform equipment installation, wiring, and commissioning operations. The swing door design is simple in structure and easy to operate, facilitating technicians' inspection and maintenance of various electrical components inside the cabinet. Furthermore, the switchgear door is usually opened using hinges, allowing personnel easy access to the internal equipment and ensuring smooth operation.
[0004] However, existing high and low voltage switchgear has some inconveniences in practical use, especially when multiple switchgear are being commissioned and installed simultaneously. Since the switchgear doors are typically hinged, opening multiple doors during equipment installation, commissioning, or maintenance occupies considerable space, leading to a cramped working environment both inside and outside the cabinet. Multiple open cabinet doors severely restrict the freedom of movement for staff, increasing the difficulty and complexity of operations, and potentially making some delicate operations difficult. Furthermore, when multiple cabinet doors are open, the cabinet and equipment may be affected by external environmental interference, creating unnecessary safety hazards. Therefore, the space limitations and operational inconveniences of the existing design urgently need improvement to enhance the efficiency of switchgear use and the ease of operation for staff.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0030] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0032] See Figure 1-11 The purpose of this utility model is to provide a high and low voltage distribution cabinet, including a cabinet body 1, a cabinet door 2 installed on the cabinet body 1, and cabinet side panels 3 installed on both sides of the cabinet body 1. The cabinet door 2 is hinged to the cabinet body 1 via a hinge structure. A mounting frame for installing power distribution equipment is fixedly connected inside the cabinet body 1. The mounting frame includes a cabinet door post 11 near the hinge of the cabinet door 2. An accommodating space is provided between the cabinet door post 11 and the cabinet side panel 3. The cabinet door 2 is provided with a control mechanism for releasing the hinge structure from the cabinet body 1. A pulley mechanism 22 is installed on the cabinet door 2. Under the operation of the user, the cabinet door 2 can slide into the accommodating space via the pulley mechanism 22, and the cabinet door 2 is hidden and stored inside the cabinet body 1.
[0033] Specifically, the top and bottom of the cabinet 1 are fixedly connected to mounting bases 4 (the bottom mounting base 4 is used as an example in the attached diagram). The mounting base 4 has a first insertion hole 42. The upper and lower ends of the cabinet door 2 are equipped with vertically movable connecting rods 38. When the two connecting rods 38 extend, they can be inserted into the first insertion hole 42, thus achieving a hinged connection between the cabinet door 2 and the cabinet 1. Alternatively, when the cabinet door 2 is opened and the two connecting rods 38 retract, the connecting rods 38 disengage from the first insertion hole 42. At this time, the cabinet door 2 is no longer hinged to the cabinet 1, and by pushing the cabinet door 2, it can be pushed into the receiving space, thus achieving a concealed storage of the cabinet door 2 inside the cabinet 1.
[0034] Furthermore, the control mechanism can control the extension and retraction of the two connecting rods 38. A cavity is provided on the side of the cabinet door 2 near the hinge point with the cabinet body 1. The control mechanism includes a gear 32 installed inside the cavity. A rotating handle 31 extending out of the cavity is fixedly connected to the gear 32. The rotating handle 31 is coaxially arranged with the gear 32, and rotating the rotating handle 31 drives the gear 32 to rotate synchronously. A ruler section 33 is symmetrically arranged on both sides of the gear 32, meshing with the gear 32. The ruler section 33 is connected to the upper and lower connecting rods 38 respectively through two telescopic rods 35. Thus, the operator can control the extension and retraction of the two connecting rods 38 by operating the rotating handle 31.
[0035] Furthermore, the control mechanism is equipped with a reset mechanism. When the rotary handle 31 is not operated, the insertion rod 38 is always in an extended state under the action of the reset mechanism. Specifically, a limiting mechanism 36 is fixedly connected inside the cavity. The limiting mechanism 36 is sleeved on the outside of the telescopic rod 35. The telescopic rod 35 is provided with an abutment part 351, and a reset spring 37 is installed between the abutment part 351 and the limiting mechanism 36.
[0036] Preferably, a slide rail base 5 is fixedly connected to the bottom of the cabinet body 1, and the slide rail base 5 is provided with a slide rail groove 51. The top of the fixed seat 4 is provided with a slide rail inlet groove 41. When the cabinet door 2 is opened to be perpendicular to the cabinet body 1, the hinge between the cabinet door 2 and the cabinet body 1 is released by operating the rotating handle 31. At this time, the cabinet door 2 is pushed inward, and the pulley 221 at the bottom of the pulley mechanism 22 can roll in the slide rail inlet groove 41 and the slide rail groove 51, so that the cabinet door 2 can better enter the receiving space.
[0037] Preferably, a base 6 is fixedly connected to the bottom of the cabinet 1. The base 6 is used to fix the mounting bracket inside the distribution box and to bear the overall weight of the distribution box.
[0038] Preferably, a support ring 7 is fixedly connected to the bottom of the cabinet door 2, and the support ring 7 is sleeved on the outside of the plug rod 38. When the cabinet door 2 is hinged to the cabinet body 1, the support ring 7 serves to support the weight of the cabinet door 2. When the cabinet door 2 is pushed inward, the support ring 7 also serves to limit the plug rod 38, preventing deformation and damage to the plug rod 38 due to resistance and jamming.
[0039] Preferably, the end of the plug rod 38 away from the cabinet door 2 is provided with a round head 39. The round head 39 can ensure that the plug rod 38 can slide smoothly in the slide rail groove 51 when the cabinet door 2 is pushed, and prevent the plug rod 38 from being deformed and damaged due to resistance jamming.
[0040] Preferably, the top end of the slide rail base 5 away from the first insertion hole 42 is provided with a second insertion hole 52. The depth of the second insertion hole 52 is less than or equal to the thickness of the round head 39. When the cabinet door 2 is pushed to the bottom of the receiving space, the round head 39 of the insertion rod 38 can be inserted into the second insertion hole 52 to temporarily limit the cabinet door 2. When the cabinet door 2 is pulled out, the round head 39 can disengage from the second insertion hole 52 and re-complete the hinged connection between the cabinet door 2 and the cabinet body 1.
[0041] In summary, in practical use, this high and low voltage distribution cabinet can achieve both opening and concealed storage of the cabinet door 2. The cabinet door 2 is connected to the cabinet body 1 via a hinged structure. The hinged connection is achieved through a vertically movable plug rod 38 and a first plug hole 42 on the fixed seat 4 on the cabinet body 1. When the plug rod 38 extends, it inserts into the first plug hole 42, thereby fixing the position of the cabinet door 2. The cabinet door 2 is equipped with a pulley mechanism 22 and a control mechanism. By rotating the rotary handle 31 in the control mechanism, the gear 32 can be driven to rotate, thereby controlling the extension and retraction of the telescopic rod 35, realizing the extension and retraction of the plug rod 38, and thus controlling the hinge connection and disengagement between the cabinet door 2 and the cabinet body 1. When it is necessary to open and conceal the cabinet door 2, the plug rod 38 is first retracted through the control mechanism to disengage the hinge, and then the cabinet door is pushed into the receiving space between the cabinet side panel 3 and the cabinet door post 11 through the pulley mechanism 22. Furthermore, the reset mechanism ensures that the plug rod 38 is always in the extended state when not in operation, while the slide rail design on the slide rail base 5 and the fixed seat 4 allows the cabinet door 2 to slide smoothly into the receiving space. When the cabinet door 2 is pushed to the bottom of the receiving space, the round head 39 of the plug rod 38 will insert into the second insertion hole 52 on the slide rail base 5, thereby temporarily limiting the cabinet door 2.
[0042] Therefore, this device saves space and improves the overall aesthetics of the distribution cabinet through its concealed cabinet door design. Secondly, the control mechanism allows for convenient and quick opening and closing of the cabinet door. Furthermore, the reset mechanism and slide rail design ensure smoother door sliding, reducing the risk of damage to the connector rods due to resistance and jamming. Finally, the second socket design on the slide rail base provides temporary door limiting, enhancing the safety and stability of the distribution cabinet. These designs make the high and low voltage distribution cabinet more convenient, efficient, and safe to use.
[0043] This high and low voltage distribution cabinet addresses the space limitations and operational inconveniences of existing technologies. By optimizing the opening method of the cabinet door, it reduces the space required for equipment installation, commissioning, and maintenance, increases the spaciousness of the operating environment and the freedom of movement for staff, and enhances the protection against the external environment, thereby improving the efficiency and ease of operation of the distribution cabinet.
[0044] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
