Description

Technical Field

[0001] This application relates to the technical field of mobile shelving, and in particular to a mobile shelving electrical cabinet. Background Technology

[0002] In the fields of power systems and industrial automation, mobile shelving units serve as the core carrier for the centralized storage and management of electrical equipment. The rationality of their structural design directly affects the installation efficiency, maintenance convenience, and space utilization of the equipment. Traditional mobile shelving units generally adopt a fixed-layer structure, which has revealed many functional defects in practical applications and is difficult to meet the needs of modern intelligent and intensive electrical equipment management.

[0003] Traditional mobile shelving units for electrical appliances typically have shelves of fixed height, with shelf spacing pre-set according to the dimensions of standardized electrical equipment. However, with the miniaturization and diversification of electrical components, the sizes of circuit breakers, relays, controllers, and other equipment vary significantly depending on their specifications. The fixed shelf structure prevents large-capacity equipment from being installed on lower shelves, while installing small equipment on higher shelves results in wasted upper space, leading to low utilization of the cabinet space.

[0004] Furthermore, the equipment is inconvenient to access. Operators need to bend down or reach into the cabinet to access deeper equipment, and for taller cabinets, ladders may even be needed to access upper-level equipment, posing a risk of falling from height. Utility Model Content

[0005] To achieve flexible adjustment and easy access, this application provides a mobile shelving unit for electrical appliances.

[0006] The mobile shelving electrical cabinet provided in this application adopts the following technical solution:

[0007] A mobile shelving unit for electrical appliances includes a base. Several cabinets are evenly mounted on the upper surface of the base. The lower rear end of each cabinet is rotatably connected to the base, and the lower front end of each cabinet is fixedly connected to the base by bolts. Several placement seats are arranged from top to bottom within each cabinet. The sides of each placement seat are slidably connected to the cabinet, and locking components that lock onto the cabinet are located on both sides of the lower end of each placement seat. A placement shell is also mounted on the upper surface of each placement seat. The placement shell is slidably connected to the placement seat, and a drive assembly is mounted on the placement seat to drive the placement shell to move back and forth. A linkage frame is mounted at the center of the lower end of each placement seat to drive the locking components on both sides to move synchronously. The linkage frame is rotatably connected to the placement seat.

[0008] By adopting the above technical solution, multiple rotatable and fixed cabinets are installed on the base, increasing the flexibility of cabinet installation and facilitating later maintenance and repair. Multiple sliding and lockable placement seats are set inside the cabinets, allowing for flexible adjustment of the seats' positions according to the size and quantity of electrical equipment, thus improving space utilization. The placement seats are equipped with movable housings that move back and forth, driven by a drive assembly, making it convenient for operators to retrieve and store electrical equipment, avoiding the inconvenience of reaching deep into the cabinet. The linkage frame allows the locking components on both sides to move synchronously, making operation even more convenient.

[0009] Optionally, the upright plate is vertically installed at both ends of the top plate, and the upright plate and the top plate are integrally formed. The inner side of the upright plate is evenly provided with a number of slots corresponding to the locking parts from top to bottom, and the inner side of the upright plate is also provided with a longitudinal groove for the placement seat to be slidably installed.

[0010] By adopting the above technical solution, the cabinet uses a one-piece molded structure for the top and vertical panels, ensuring the overall strength and stability of the cabinet. The slots on the inner side of the vertical panels, in conjunction with locking mechanisms, reliably lock the position of the placement base, preventing it from sliding during use. The longitudinal grooves provide guidance for the sliding of the placement base, making its movement smoother.

[0011] Optionally, the front and rear ends of the upright plate are provided with a rear ear seat and a front ear seat. The rear ear seat is rotatably connected to the base, and the front ear seat is fixedly connected to the base by bolts. The rear ear seat, the front ear seat and the upright plate are integrally formed.

[0012] By adopting the above technical solution, rear and front lugs are set at both ends of the upright panel. The rear lugs are rotatably connected to the base, and the front lugs are fixedly connected to the base with bolts. This structure allows the cabinet to rotate around the rear lugs for convenient internal inspection and maintenance, while also ensuring stability during use by being fixed to the base with bolts. The one-piece molding design further improves the connection strength between the upright panel and the lugs.

[0013] Optionally, the placement seat includes a seat plate and a top frame. The top frame is installed on the upper end surface of the seat plate and is integrally formed with the seat plate. The two sides of the seat plate are provided with sliders that slide in cooperation with the longitudinal groove, and the lower end surface of the seat plate is also provided with a guide frame for sliding installation of the locking element. The sliders and the guide frame are integrally formed with the seat plate.

[0014] By adopting the above technical solution, the base plate and top frame of the placement stand are integrally molded, ensuring the overall structural strength of the placement stand. The sliders on both sides of the base plate slide in conjunction with the longitudinal grooves of the cabinet uprights, allowing the placement stand to slide smoothly up and down within the cabinet. The guide frame on the lower end face of the base plate provides guidance for the sliding of the locking components, ensuring that the locking components can accurately engage with the slots in the cabinet.

[0015] Optionally, the locking element includes a horizontal sliding plate and a support spring, wherein the horizontal sliding plate is slidably mounted in the guide frame, and the support spring is fixedly mounted between the seat plate and the horizontal sliding plate.

[0016] By adopting the above technical solution, the locking component uses a horizontal sliding plate and a support spring. The support spring provides elastic support to the horizontal sliding plate, allowing it to be tightly engaged in the slot of the cabinet under normal conditions, thus locking the placement seat. When the position of the placement seat needs to be adjusted, the horizontal sliding plate can be disengaged from the slot by overcoming the spring force, making operation convenient.

[0017] Optionally, a positioning shell is provided in the middle of the placement shell, and a threaded tube that cooperates with the drive assembly is installed in the positioning shell, and the threaded tube is fixedly connected to the positioning shell.

[0018] By adopting the above technical solution, the positioning shell and threaded tube located in the middle of the placement shell, in cooperation with the screw of the drive assembly, can convert the rotational motion of the motor into the linear motion of the placement shell, realizing the forward and backward movement of the placement shell. The threaded tube is fixedly connected to the positioning shell, ensuring the stability and reliability of the transmission.

[0019] Optionally, the drive assembly includes a motor and a screw that mates with a threaded tube. The motor is fixedly mounted on the outer side of the top frame, and the screw is connected to the output end of the motor.

[0020] By adopting the above technical solution, the drive component uses a combination of a motor and a screw. The motor is fixed on the outer side of the top frame, and the rotation of the screw drives the placement shell connected to the threaded tube to move back and forth. This transmission method has a simple structure, high transmission efficiency, and can precisely control the movement position of the placement shell, making it convenient for operators to retrieve and discharge electrical equipment.

[0021] Optionally, the linkage frame includes a top plate, a linkage side rod, and an operating panel. The top plate is rotatably mounted at the center of the lower end face of the seat plate, and two sets of eccentric shafts are provided on the lower end face of the top plate. The two ends of the linkage side rod are rotatably connected to the eccentric shafts and the horizontal sliding plate, respectively. The operating panel is fixedly mounted on the lower end face of the top plate.

[0022] By adopting the above technical solution, the top plate of the linkage frame is rotatably mounted at the center of the lower end face of the seat plate. By rotating the top plate with the operating panel, the eccentric shaft on the lower end face of the top plate drives the linkage side rod to move, thereby causing the horizontal sliding plates on both sides to move synchronously. This ingenious structural design allows for the synchronous unlocking and locking of the locking parts on both sides to be achieved with only one operating panel, improving operational efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects: The sliding and lockable placement seat in the cabinet of this application can be flexibly adjusted in position according to the actual situation of the electrical equipment, making full use of the internal space of the cabinet and avoiding the space waste caused by the fixed placement layer of traditional electrical cabinets. The placement shell on the placement seat can move back and forth through the drive component, allowing operators to easily retrieve and place electrical equipment without having to enter the cabinet, reducing operational difficulty and improving work efficiency. The cabinet and base are connected by rotation and bolts, facilitating internal inspection and maintenance when needed, while ensuring stability during use. The linkage frame allows the locking parts on both sides to move synchronously, and the placement seat can be unlocked and locked with just one control panel, making operation more convenient.

A placement shell 5 is also mounted on the upper surface of each placement seat 3, slidably connected to the placement seat 3. A drive assembly 6 is mounted on the placement seat 3 to drive the placement shell 5 to move back and forth. A linkage frame 7 is mounted at the center of the lower end of each placement seat 3 to drive the locking elements 4 on both sides to move synchronously, and the linkage frame 7 is rotatably connected to the placement seat 3. The mounting of multiple rotatable and fixed cabinet bodies 2 on the base 1 increases the flexibility of cabinet body 2 installation and facilitates later maintenance and repair. The cabinet 2 is equipped with multiple sliding and locking placement seats 3, whose positions can be flexibly adjusted according to the size and number of electrical appliances, improving space utilization. The placement seats 3 are fitted with movable housings 5, driven by a drive assembly 6, facilitating easy access for operators to retrieve electrical equipment and avoiding the inconvenience of reaching deep into the cabinet. The linkage frame 7 allows the locking components 4 on both sides to move synchronously, making operation even more convenient.

[0033] Reference Figure 1 and Figure 2As shown, the cabinet 2 includes a top plate 21 and upright plates 22. The upright plates 22 are vertically installed at both ends of the top plate 21 and are integrally formed with the top plate 21. Several slots 201 corresponding to the locking elements 4 are evenly formed from top to bottom on the inner side of the upright plates 22. A longitudinal groove 202 for sliding installation of the placement seat 3 is also formed on the inner side of the upright plates 22. The cabinet 2's integrally formed structure of the top plate 21 and upright plates 22 ensures the overall strength and stability of the cabinet 2. The slots 201 on the inner side of the upright plates 22 cooperate with the locking elements 4 to reliably lock the position of the placement seat 3, preventing it from sliding during use. The longitudinal groove 202 provides guidance for the sliding of the placement seat 3, making its movement smoother. The upright plate 22 has rear ear seats 221 and front ear seats 222 at its front and rear ends. The rear ear seats 221 are rotatably connected to the base 1, and the front ear seats 222 are fixedly connected to the base 1 by bolts. The rear ear seats 221, front ear seats 222, and upright plate 22 are integrally formed. This structure allows the cabinet 2 to rotate around the rear ear seats 221 for convenient internal inspection and maintenance, while also ensuring stability during use by being fixed to the base 1 by bolts. The integrally formed design further improves the connection strength between the upright plate 22 and the ear seats.

[0034] Reference Figure 3 and Figure 4 As shown, the placement seat 3 includes a seat plate 31 and a top frame 32. The top frame 32 is installed on the upper surface of the seat plate 31 and is integrally formed with the seat plate 31. Slider blocks 311 are provided on both sides of the seat plate 31, which slide in conjunction with the longitudinal groove 202. A guide frame 312 for sliding installation of the locking element 4 is also provided on the lower surface of the seat plate 31. The sliders 311 and guide frame 312 are integrally formed with the seat plate 31.

The sliders 311 on both sides of the seat plate 31 slide in conjunction with the longitudinal groove 202 of the cabinet 2's upright plate 22, allowing the placement seat 3 to slide smoothly up and down within the cabinet 2. The guide frame 312 on the lower surface of the seat plate 31 provides guidance for the sliding of the locking element 4, ensuring that the locking element 4 accurately engages with the slot 201 of the cabinet 2.

[0035] Reference Figure 3 and Figure 5As shown, the locking component 4 includes a horizontal sliding plate 41 and a support spring 42. The horizontal sliding plate 41 is slidably mounted in the guide frame 312, and the support spring 42 is fixedly mounted between the seat plate 31 and the horizontal sliding plate 41. The locking component 4 uses the structure of the horizontal sliding plate 41 and the support spring 42. The support spring 42 provides elastic support for the horizontal sliding plate 41, allowing it to be tightly engaged in the slot 201 of the cabinet 2 under normal conditions, thus locking the placement seat 3. When the position of the placement seat 3 needs to be adjusted, the horizontal sliding plate 41 can be disengaged from the slot 201 by overcoming the spring force, making operation convenient.

[0036] Reference Figure 6 As shown, a positioning shell 51 is provided in the middle of the placement shell 5. A threaded tube 511 that mates with the drive assembly 6 is installed in the positioning shell 51, and the threaded tube 511 is fixedly connected to the positioning shell 51. The positioning shell 51 and the threaded tube 511 in the middle of the placement shell 5, in conjunction with the screw 62 of the drive assembly 6, can convert the rotational motion of the motor 61 into the linear motion of the placement shell 5, realizing the forward and backward movement of the placement shell 5. The fixed connection between the threaded tube 511 and the positioning shell 51 ensures the stability and reliability of the transmission.

[0037] Reference Figure 4 As shown, the drive assembly 6 includes a motor 61 and a screw 62 that mates with the threaded tube 511. The motor 61 is fixedly mounted on the outer side of the top frame 32, and the screw 62 is connected to the output end of the motor 61. The drive assembly 6 uses a combination of the motor 61 and the screw 62. The motor 61 is fixed to the outer side of the top frame 32, and by driving the screw 62 to rotate, it drives the placement shell 5 connected to the threaded tube 511 to move back and forth. This transmission method has a simple structure, high transmission efficiency, and can accurately control the movement position of the placement shell 5, making it convenient for operators to retrieve and discharge electrical equipment. The motor 61 can be a stepper motor 61 of model 57HS76, which has the advantages of high torque, high precision, and stable operation, and can meet the movement requirements of the placement shell 5.

[0038] Reference Figure 5 As shown, the linkage frame 7 includes a top plate 71, a linkage side rod 72, and an operating panel 73. The top plate 71 is rotatably mounted at the center of the lower end face of the seat plate 31, and two sets of eccentric shafts 711 are provided on the lower end face of the top plate 71. The two ends of the linkage side rod 72 are rotatably connected to the eccentric shafts 711 and the horizontal slide plate 41, respectively. The operating panel 73 is fixedly mounted on the lower end face of the top plate 71. The top plate 71 of the linkage frame 7 is rotatably mounted at the center of the lower end face of the seat plate 31. By rotating the top plate 71 through the operating panel 73, the eccentric shafts 711 on the lower end face of the top plate 71 drive the linkage side rod 72 to move, thereby causing the horizontal slide plates 41 on both sides to move synchronously. This ingenious structural design allows for the synchronous unlocking and locking of the locking parts 4 on both sides with only one operating panel 73, improving operational efficiency.

[0039] The implementation principle of a mobile shelving unit for electrical appliances according to this application embodiment is as follows: When installation is required, the bolts on the front ear seat 222 can be removed, allowing the cabinet 2 to be flipped and tilted, making it easy to install the placement seat 3 from the cabinet 2. When the position of the placement seat 3 needs to be adjusted, the operating panel 73 is rotated, which drives the locking parts 4 on both sides to move synchronously through the linkage frame 7, causing the horizontal sliding plate 41 to disengage from the slot 201 of the cabinet 2. At this time, the placement seat 3 can be slid up and down along the longitudinal groove 202 to a suitable position. Then, the operating panel 73 is released, and under the action of the support spring 42, the horizontal sliding plate 41 is locked back into the slot 201, thus locking the placement seat 3. When it is necessary to retrieve or place electrical equipment inside the placement shell 5, the motor 61 is started. The motor 61 drives the screw 62 to rotate, which drives the placement shell 5 to move back and forth through the threaded tube 511, making it convenient for operators to retrieve and place electrical equipment.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
