Description

Technical Field

[0001] This utility model relates to the field of power cabinet technology, specifically a modular power cabinet with expandable functions. Background Technology

[0002] With the continuous development of society, there are more and more electrical devices. Power cabinets are often used in power engineering. Power cabinets are mainly power distribution cabinets that connect other electrical devices to the power supply. At the same time, power cabinets can protect electrical equipment. Therefore, modular power cabinets are needed to meet the usage requirements.

[0003] According to the patent disclosed in announcement number CN218770788U, a modular power cabinet includes a cabinet body, a base, and a movable frame. The cabinet body is fixedly installed on the inner side of the base. An insulating plate is slidably installed on the inner wall of the cabinet body. An mounting frame is fixedly installed between the insulating plates. A rotating rod is movably installed on the bottom of the base. Support seats are movably installed on the bottom of the base on both sides of the rotating rod. Support feet are fixedly installed on the bottom of the support seats. Protrusions that cooperate with the support seats are fixedly installed at both ends of the rotating rod.

[0004] The above solution effectively improves convenience, allowing for easy adjustment of the storage space according to the installation requirements of electrical equipment. It also effectively isolates power from leakage in electrical equipment, preventing electric shock and enhancing safety. However, while this solution allows for easy adjustment of the storage space, the total internal storage space of the power cabinet is fixed and lacks expandability. As servers and other equipment expand, the demands on power supply capacity and the number of interfaces increase. Without effective space expansion, frequent replacement of power cabinets is necessary, which is not only costly but also leads to business interruptions and disrupts normal operations, thus presenting certain shortcomings. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a modular power cabinet with expandable functions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular power cabinet with expandable functionality, comprising a base, two sets of casters fixedly mounted on the bottom of the base, a cabinet body fixedly connected to the top of the base, an expandable cabinet slidably connected to the outer surface of the cabinet body, a lifting mechanism on the outer side of the cabinet body, a cabinet door hinged to the front of the cabinet body, a limiting mechanism in front of the cabinet door, an expandable door inserted inside the cabinet door, a pull ring fixedly connected to the top of the outer surface of the expandable door, and a set of insertion holes opened inside the expandable door.

[0007] Furthermore, the lifting mechanism includes a fixed plate fixedly connected to the outer surface of the cabinet, a rotating shaft rotatably connected to the inner wall of the fixed plate, and a knob fixedly connected to one end of the rotating shaft.

[0008] Furthermore, the other end of the knob is fixedly connected to a drive gear, and the outer surface of the drive gear is meshed with a driven gear, which rotates with the cabinet.

[0009] Furthermore, an adjusting screw is fixedly connected to the outer surface of the driven gear. The adjusting screw rotates with the cabinet and is screwed to the expansion cabinet.

[0010] Furthermore, the limiting mechanism includes a plug rod that is slidably connected to the inner wall of the cabinet door, and the plug rod is inserted into a plug hole. A connecting piece is fixedly connected to the end of the plug rod away from the cabinet door, and a pull rod is fixedly connected to the outer surface of the connecting piece.

[0011] Furthermore, an elastic element is sleeved on the outer surface of the insertion rod, one end of which is fixedly connected to the outer surface of the cabinet door, and the other end of which is fixedly connected to the outer surface of the connecting piece.

[0012] Compared with existing technologies, this modular power supply cabinet with expandable functions has the following advantages:

[0013] This utility model, by setting up a lifting mechanism, can adjust the height of the expansion cabinet, thereby expanding the storage space of the cabinet. By setting up an expansion door, the height of the cabinet door can be expanded. By setting up a limiting mechanism and a socket, the expansion door can be positioned. Through the coordinated use of the lifting mechanism, expansion cabinet, expansion door, limiting mechanism, and socket, the modular power cabinet can be expanded, effectively solving the problem of the fixed total internal capacity of the power cabinet. It meets the increasing demand for power supply capacity and number of interfaces as equipment expands, avoiding the high cost and business interruption risk of frequent power cabinet replacements due to insufficient space.

[0014] This invention enables the connecting piece and the insert rod to move by pulling the pull rod, which stretches the elastic element. At this time, the elastic element will deform and store a certain elastic potential energy. When the pull rod is released, the stretched elastic element will release the elastic potential energy, which will drive the insert rod, the connecting piece and the pull rod to move in the opposite direction, thereby achieving the effect of rapid reset of the insert rod, the connecting piece and the pull rod.

Detailed Implementation

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] This embodiment provides a modular power cabinet with expansion capabilities. By setting a lifting mechanism 5, the height of the expansion cabinet 4 can be adjusted, thereby expanding the storage space of the cabinet 3. By setting an expansion door 8, the height of the cabinet door 6 can be expanded. By setting a limiting mechanism 7 and a socket 10, the expansion door 8 can be positioned. Through the coordinated use of the lifting mechanism 5, expansion cabinet 4, expansion door 8, limiting mechanism 7, and socket 10, the expansion effect of the modular power cabinet can be achieved. This effectively solves the problem of a fixed total internal capacity of the power cabinet, meeting the increasing demand for power supply capacity and interface quantity as equipment expands. It avoids the high costs and business interruption risks associated with frequent power cabinet replacements due to insufficient space.

[0023] See Figures 1-5 A modular power cabinet with expandable functions has a reasonable and compact overall structure design. All components work together to achieve efficient expansion and convenient use of the power cabinet.

[0024] Its core components include a base 1, which is made of high-strength steel and has a rectangular structure. It has excellent pressure resistance and load-bearing capacity. Two sets of moving wheels 2 are fixedly installed at the bottom of the base. The moving wheels 2 are made of wear-resistant rubber material with a braking device, which makes it easy to push the power cabinet when it needs to be moved, and can also be braked stably when it is in fixed use to prevent displacement.

[0025] The top of the base 1 is fixedly connected to the cabinet 3 by a sturdy welding process. The cabinet 3 is rectangular in shape and the outer shell is made of rust-resistant aluminum alloy, which not only ensures the sturdiness of the cabinet 3, but also helps with heat dissipation.

[0026] An extension cabinet 4 is slidably connected to the outer surface of cabinet 3. The size of the extension cabinet 4 is adapted to that of cabinet 3, and its material is the same as that of cabinet 3. The sliding connection structure between the two is cleverly designed, which allows the extension cabinet 4 to slide smoothly up and down on cabinet 3, ensuring stability and smoothness when expanding the space, effectively avoiding shaking or jamming, and providing a reliable guarantee for expanding storage space.

[0027] A set of lifting mechanisms 5 is provided on the outside of the cabinet 3. The lifting mechanism 5 plays a key role in expanding the storage space of the cabinet 3. The fixing plate 501 is firmly fixed to the outer surface of the cabinet 3 by bolts, providing a stable support base for the rotating shaft 502. The rotating shaft 502 is made of stainless steel, which is hard and corrosion resistant. It passes through the inner wall of the fixing plate 501 and is rotatably connected to it. A knob 503 is fixedly connected to one end of the rotating shaft 502. The surface of the knob 503 has anti-slip texture, which makes it convenient for users to apply force when operating.

[0028] The other end of the knob 503 is fixedly connected to the drive gear 504. The meshing connection between the drive gear 504 and the driven gear 505 is precisely designed. When the drive gear 504 rotates, it can accurately drive the driven gear 505 to rotate. The driven gear 505 rotates with the cabinet 3 through a high-quality bearing, ensuring smooth rotation and low resistance.

[0029] An adjusting screw 506 is fixedly connected to the outer surface of the driven gear 505. The adjusting screw 506 is also made of stainless steel. It rotates with the cabinet 3 and is screwed to the expansion cabinet 4. This screwing method allows the rotational motion of the adjusting screw 506 to be efficiently converted into the linear lifting motion of the expansion cabinet 4, so as to achieve precise adjustment of the height of the expansion cabinet 4, thereby flexibly expanding the storage space of the cabinet 3 and meeting the storage needs of different numbers and sizes of equipment.

[0030] The cabinet door 6 is hinged to the front of the cabinet body 3. The hinge structure between the cabinet door 6 and the cabinet body 3 ensures that the cabinet door 6 can be opened and closed smoothly, making it convenient for users to operate and maintain the internal equipment.

[0031] A limiting mechanism 7 is provided in front of the cabinet door 6. The limiting mechanism 7 plays a crucial role in positioning the cabinet door 6 and the extension door 8.

[0032] The insertion rod 701 in the limiting mechanism 7 is cylindrical and made of high-strength plastic with a smooth surface. It slides smoothly and unobstructedly with the inner wall of the cabinet door 6. The insertion rod 701 and the insertion hole 10 fit tightly together, which can effectively prevent the expansion door 8 from sliding accidentally.

[0033] A connecting piece 702 is fixedly connected to the end of the plug rod 701 away from the cabinet door 6. The connecting piece 702 is flat, and a pull rod 703 is fixedly connected to its outer surface. The pull rod 703 is made of metal and has been treated with anti-rust treatment to make it easy for users to hold and pull.

[0034] The outer surface of the insertion rod 701 is fitted with an elastic element 704. The elastic element 704 is made of high-quality spring steel, which has good elasticity and durability. One end of the elastic element 704 is fixedly connected to the outer surface of the cabinet door 6, and the other end is fixedly connected to the outer surface of the connecting piece 702. This structural design allows the elastic element 704 to deform stably and store elastic potential energy when the pull rod 703 is pulled. After the pull rod 703 is released, the elastic potential energy is released quickly, which drives the insertion rod 701, the connecting piece 702 and the pull rod 703 to quickly reset, ensuring the stable operation of the limit mechanism 7, effectively realizing the positioning of the expansion door 8, and ensuring the safety and reliability of the power cabinet during use.

[0035] An extension door 8 is inserted inside the cabinet door 6. The material of the extension door 8 is the same as that of the cabinet door 6. A pull ring 9 is fixedly connected to the top of its outer surface. The pull ring 9 is a round metal ring, which makes it convenient for users to grip and pull the extension door 8.

[0036] The interior of the expansion door 8 is provided with a set of insertion holes 10. The position and size of the insertion holes 10 are precisely matched with the insertion rod 701 to ensure that the insertion rod 701 can be accurately inserted and to achieve effective positioning of the expansion door 8.

[0037] Working principle: When it is necessary to expand the storage space of cabinet 3, rotate the knob 503 in the lifting mechanism 5. The knob 503 drives the drive gear 504 to rotate. The drive gear 504 meshes with the driven gear 505, causing the adjusting screw 506 to rotate. Since the adjusting screw 506 is screwed to the expansion cabinet 4 and the expansion cabinet 4 is slidably connected to the cabinet 3, the expansion cabinet 4 can slide up and down on the outer surface of the cabinet 3 to adjust the height. When it is necessary to open the expansion door 8 on the cabinet door 6, pull the lever 703 in the limiting mechanism 7. 03 The connecting piece 702 drives the insertion rod 701 to overcome the elastic force of the elastic element 704 and pull it out from the socket 10 located above the expansion door 8. At this time, the expansion door 8 can be pulled upward by the pull ring 9 until its height is level with the height of the expansion cabinet 4. Then, the pull rod 703 is released, and the elastic element 704 releases its elastic potential energy, causing the insertion rod 701 to be reinserted into the socket 10 located below, thereby achieving the positioning effect of the expansion door 8. Through the coordinated work of these components, the expansion function of the modular power cabinet is realized to meet different needs.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
