Description

Technical Field

[0001] This invention relates to the field of power distribution cabinets, and more specifically, to a novel power distribution cabinet and its usage method. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] The prior art discloses an assembled distribution cabinet (CN112968380B), including a base box. The base box has a base sealing groove on its top, and a sealing strip is fixedly connected to the inner wall of the base sealing groove. A connecting box is fixedly connected to the top of the sealing strip, and the connecting box has a connecting sealing groove on its top. Rotation control devices are fixedly connected to the inner walls of both the base box and the connecting box. A mounting plate is fixedly connected to one side of the rotation control device. Sealing ears are fixedly connected to one side of both the base box and the connecting box. A sealing plate is slidably connected to the inner wall of the sealing ear. Plugs are fixedly connected to both ends of the top side of the sealing plate. This invention relates to the field of distribution cabinet technology. This novel distribution cabinet is easily adaptable to different usage environments, convenient to use, makes full use of the internal space of the distribution cabinet, and eliminates the need for maintenance personnel to walk to the other side of the distribution cabinet, resulting in a better user experience. It also avoids the mounting plate from rotating arbitrarily, facilitating maintenance.

[0004] The aforementioned device cannot be connected to any other part of the main body of the distribution cabinet. It cannot achieve controllability and convenience of connection through its internal structure. Connection to external media is prone to errors in terms of neatness, resulting in poor visual effect after assembly and a complicated assembly process. Therefore, we have made improvements and proposed a new type of distribution cabinet. Summary of the Invention

[0005] The purpose of this invention is to provide a novel power distribution cabinet. By incorporating a linkage component, a threaded rod and a threaded cylinder are connected within the linkage plate. The rotation of the threaded cylinder causes the linkage plate to move outward. At this point, the movable locking block and the connecting slot can be interlocked to ensure a stable connection between the power distribution cabinet bodies. This solves the problem that when connecting to other parts of the power distribution cabinet, the internal structure cannot achieve controllability and convenience of the connection. Connections to external media are prone to errors in neatness, resulting in poor visual effects after assembly and a complex assembly process.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0007] A novel power distribution cabinet includes a cabinet body, a connecting groove at the right end of the cabinet body, and a connecting slot at the left end of the cabinet body. It also includes:

[0008] A linkage component is used to link two adjacent power distribution cabinets. The linkage component includes a movable block that is embedded in a connecting slot and a threaded rod and a threaded cylinder that push the movable block to slide.

The threaded rod and the threaded cylinder are connected to each other through the linkage plate. The rotation of the threaded cylinder drives the linkage plate to move outward. At this time, the movable block and the connecting slot can be interlocked to ensure the stable connection between the power distribution cabinets.

[0009] The positioning component, located at the left end of the linkage plate, is used for positioning the threaded rod. The positioning component includes a sliding rod and a sliding seat that push the linkage plate to slide. When the linkage plate expands outward, it can drive the sliding seat of the sliding rod connected to the left end to slide, thereby causing the linkage rod outside the sliding seat to rotate along the positioning shaft. At this time, the gear at the outer end of the positioning shaft meshes with the gear ring at the outer end of the threaded rod, thereby ensuring linkage stability and limiting the threaded rod under the setting of the sector groove.

[0010] The lifting assembly is used to raise and position the power distribution cabinet after the assembly is completed. The lifting assembly includes a protrusion fixed to the right end of the movable locking block and an inclined plate and slide rail that drive the lifting assembly in conjunction. The locking plate slides along the track, causing the lower end of the locking plate to drive the spiral rod to move inward. The spiral rod drives the bevel gear to rotate. At this time, the bevel gear drives the rotating rod to rotate. When the movable locking block slides, it drives the outermost protrusion at the bottom to push the inclined plate down, which can ensure that the two adjacent rotating rods are stably engaged and connected and rotate synchronously.

The number of slide rods is set to two sets. The slide rod is slidably connected to the sliding seat. The outer end of the sliding seat is movably connected to the linkage rod. By sliding the sliding seat, the linkage rod can move in two directions, and then rotate through the positioning shaft.

[0014] As a preferred technical solution of this application, the outer end of the linkage rod is provided with a gear, and the gear is fixedly connected to the linkage rod. The gear meshes with the gear ring, and the inner end of the gear is provided with a positioning shaft. The positioning shaft is movably connected to the gear. Through the connection between the gear and the positioning shaft, the position of the threaded rod can be conveniently defined.

[0015] As a preferred technical solution of this application, the outer end of the linkage rod is provided with a sector-shaped groove, the positioning shaft is fixedly installed in the sector-shaped groove, the sector-shaped groove is embedded in the inner end of the connecting groove, and the linkage rod rotates along the sector-shaped groove through the positioning shaft. By providing the sector-shaped groove, the range and area of ​​motion required for the linkage rod to move can be well simulated.

[0016] As a preferred technical solution of this application, the outer end of the movable card block is attached with a card plate, the outer end of the card plate is provided with a card rail, the card plate slides along the card rail, and the card rail is embedded in both sides of the power distribution cabinet. By providing the card rail, the sliding of the card plate can be facilitated.

[0017] As a preferred technical solution of this application, the right end of the movable block is fixedly connected to the protrusion, the protrusion pushes the inclined plate to slide down along the slide rail, and the outer end of the inclined plate is movably connected to a linkage rod. The cross-sectional shape of the linkage rod is square, and the outer end of the linkage rod is provided with a locking hole. The linkage rod slides along the locking hole. By providing the locking hole, the linkage rod can slide conveniently according to certain limiting conditions.

By providing the bevel gear, it is easy for the helical rod to mesh with it to realize the rotation of the worm gear.

[0019] As a preferred technical solution of this application, the lower end of the bevel gear is provided with a helical rod, the helical rod is fixedly connected to the clamping plate, the outer end of the rotating rod is provided with a threaded short cylinder, and the lower end of the threaded short cylinder is provided with a lifting frame. By providing the threaded short cylinder, the lifting frame can be raised and lowered through the thread between the two when the rotating rod rotates.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the scheme of this application:

[0022] 1. By setting up a linkage component, the threaded rod and threaded cylinder in the linkage plate are connected to each other.

[0024] 3. Through the coordinated setup of the linkage component and the positioning component, the linkage component pushes the linkage plate outward, while the movable block engages in the corresponding connecting slot. Simultaneously, the gear ring and gear in the positioning component mesh with each other, thereby limiting the movement of the threaded rod, thus making it easier to stably assemble the distribution cabinets.

[0025] 4. By setting up a lifting component, the card plate slides along the card rail, causing the lower end of the card plate to drive the spiral rod to move inward, and the spiral rod drives the bevel gear to rotate. At this time, the bevel gear drives the rotating rod to rotate, and when the movable card block slides, it drives the outermost protrusion at the bottom to push the inclined plate down, which can ensure that the two adjacent rotating rods are stably engaged and connected, and rotate synchronously.

[0043] Please see Figures 1 to 9 This invention provides a technical solution: a novel power distribution cabinet, comprising a cabinet body 1, a connecting groove 2 at the right end of the cabinet body 1, and a connecting slot 3 at the left end of the cabinet body 1, and further comprising:

[0044] A linkage component is used to link two adjacent power distribution cabinets 1. The linkage component includes a movable block 4 that is embedded in a connecting slot 3 and a threaded rod 5 and a threaded cylinder 6 that push the movable block 4 to slide. The outer end of the threaded cylinder 6 is provided with a through hole 7 and the outer end of the through hole 7 is provided with a linkage plate 8.

[0045] By setting up the linkage components, the two power distribution cabinets can be easily assembled;

[0046] A positioning component, located at the left end of the linkage plate 8, is used for positioning the threaded rod 5. The positioning component includes a slide rod 9 that pushes the linkage plate 8 to slide and a slide seat 10.

[0047] By setting the positioning component, it is possible to define the position of the two power distribution cabinets connected to the linkage component;

[0048] The lifting assembly is used to raise and position the power distribution cabinet after the assembly is completed. The lifting assembly includes a protrusion 16 fixed to the right end of the movable block 4 and an inclined plate 17 and a slide rail 18 that drive the lifting assembly in linkage.

[0049] With the addition of a lifting mechanism, the entire distribution cabinet can be raised after assembly.

[0050] The movable locking block 4 is engaged with the connecting slot 3, and the number of movable locking blocks 4 is set to two sets, with two movable locking blocks 4 in each set. The threaded rod 5 is connected to the through hole 7, and the through hole 7 passes through the outer surfaces of the left and right ends of the linkage plate 8. The threaded cylinder 6 is wrapped around the outer end of the threaded rod 5, and the threaded cylinder 6 is connected to the threaded rod 5 by a thread.

[0051] First, the design of the movable card block 4 and the connecting card slot 3 allows for easy connection and assembly of the two power distribution cabinets;

[0052] Secondly, the threaded rod 5 passes through the through hole 7 and comes into contact with the threaded cylinder 6, causing the threaded cylinder 6 to move, which facilitates the movement of the linkage plate 8.

[0053] Furthermore, the threaded cylinder 6 has a certain limit within the linkage plate 8, which can better drive the movement of the threaded rod 5.

[0054] The threaded rod 5 has a toothed ring at its tail end. The threaded cylinder 6 rotates along the inner end of the through hole 7 and is engaged in the inner end of the linkage plate 8. The linkage plate 8 is movably connected to the movable block 4.

[0055] The toothed ring here allows the threaded rod 5 to be better limited.

[0056] The threaded rod 5 inside the linkage plate 8 is connected to the threaded cylinder 6. The rotation of the threaded cylinder 6 drives the linkage plate 8 to move outward. At this time, the movable card block 4 and the connecting card slot 3 can be interlocked to ensure the stable connection between the power distribution cabinets 1.

[0057] Please see Figures 4 to 7 The present invention provides a technical solution: the slide rod 9 is fixedly installed on the inner surface of the left end of the linkage plate 8, the number of the slide rod 9 is set to two sets, the slide rod 9 is slidably connected to the sliding seat 10, and the outer end of the sliding seat 10 is movably connected to the linkage rod 13.

[0058] First, the design of the slide bar 9 facilitates the connection between the linkage plate 8 and the sliding seat 10;

[0059] Secondly, the sliding seat 10 slides along the sliding rod 9, which facilitates the conversion between rotation angle and translation angle when the linkage rod 13 moves.

[0060] The outer end of the linkage rod 13 is provided with a gear, and the gear is fixedly connected to the linkage rod 13. The gear meshes with the gear ring. The inner end of the gear is provided with a positioning shaft 11, and the positioning shaft 11 is movably connected to the gear.

[0061] First, the gear can limit the toothed ring on the threaded rod 5 to ensure the stability of the connection between the distribution cabinets;

[0062] Secondly, the gear rotates along the positioning shaft 11, ensuring the stable connection of the linkage rod 13.

[0063] The outer end of the linkage rod 13 is provided with a sector-shaped groove 12, the positioning shaft 11 is fixedly installed in the sector-shaped groove 12, the sector-shaped groove 12 is embedded in the inner end of the connecting groove 2, and the linkage rod 13 rotates along the sector-shaped groove 12 through the positioning shaft 11.

[0064] First, the linkage rod 13 is driven to rotate through the positioning shaft 11, and is subjected to force by the sliding seat 10 and the linkage plate 8;

[0065] Secondly, the sector groove 12 provides space for the rotation of the linkage rod 13.

[0066] The outer end of the movable card block 4 is attached with a card plate 14, and the outer end of the card plate 14 is provided with a card rail 15. The card plate 14 slides along the card rail 15, and the card rail 15 is embedded in both sides of the power distribution cabinet 1.

[0067] First, the arrangement of the card plate 14 enables the connection interface for assembling two power distribution cabinets via the card rail 15;

[0068] Secondly, the screw rod 25 can also be connected through the clamp plate 14, so that the movement of the screw rod 25 drives the rotation of the bevel gear 23, and the rotation of the screw rod 25 is supported by a power component, such as a motor or electric motor.

[0069] When the linkage plate 8 expands outward, it can drive the sliding seat 10 of the sliding rod 9 connected to the left end to slide, thereby causing the linkage rod 13 outside the sliding seat 10 to rotate along the positioning shaft 11. At this time, the gear at the outer end of the positioning shaft 11 meshes with the gear ring at the outer end of the threaded rod 5, thereby ensuring linkage stability and limiting the threaded rod 5 under the setting of the sector groove 12.

[0070] Please see Figures 8 to 9 The present invention provides a technical solution: the right end of the movable card block 4 is fixedly connected to the protrusion 16, the protrusion 16 pushes the inclined plate 17 to slide down along the slide rail 18, the outer end of the inclined plate 17 is movably connected to the linkage card rod 19, the cross-sectional shape of the linkage card rod 19 is square, the outer end of the linkage card rod 19 is provided with a card hole 20, and the linkage card rod 19 slides along the card hole 20.

[0071] First, the design of the protrusion 16 is to ensure that the inclined plate 17 can slide down the slide rail 18 and then be engaged between the linkage rod 19 and the locking hole 20;

[0072] Secondly, the linkage lever 19 slides along the locking hole 20, which can greatly ensure the stability of the sliding limit;

[0073] Furthermore, the inclined plate 17 and the slide rail 18 are slidably connected, and there is a connecting structure between them to ensure that the inclined plate 17 will not derail.

[0074] The left end of the linkage lever 19 is provided with a retaining sleeve 22, and the linkage lever 19 and the retaining sleeve 22 are fixedly connected. The left end of the retaining sleeve 22 is provided with a retaining groove 21, and the outer end of the retaining groove 21 is provided with a bevel gear 23. The retaining groove 21 is embedded in the inner surface of the right end of the bevel gear 23. The left end of the bevel gear 23 is provided with a rotating rod 24, and the bevel gear 23 and the rotating rod 24 are fixedly connected.

[0075] First, the design of the locking cylinder 22 facilitates the sliding and locking positioning of the linkage locking rod 19;

[0076] Secondly, the connection between the bevel gear 23 and the rotating rod 24 can stably ensure the stable lifting of the lifting frame 27.

[0077] The lower end of the bevel gear 23 is provided with a helical rod 25, which is fixedly connected to the clamping plate 14. The outer end of the rotating rod 24 is provided with a threaded short cylinder 26, and the lower end of the threaded short cylinder 26 is provided with a lifting frame 27.

[0078] First, the lifting frame 27 has a limit condition for lifting, which can ensure that the lifting frame 27 is lifted stably;

[0079] Furthermore, the lower end of the lifting frame 27 is equipped with sliding components, such as pulleys, which can reduce friction and improve the smoothness of lifting when the lifting frame 27 is lifted.

[0080] The sliding of the locking plate 14 along the locking rail 15 causes the lower end of the locking plate 14 to drive the spiral rod 25 to move inward, and the spiral rod 25 drives the bevel gear 23 to rotate. At this time, the bevel gear 23 drives the rotating rod 24 to rotate, and when the movable locking block 4 slides, it drives the outermost protrusion 16 at the bottom to push the inclined plate 17 to move down, which can ensure that the two adjacent rotating rods 24 are stably locked and connected, and rotate synchronously.

[0081] When stable connection and assembly of the power distribution cabinet 1 is required, external screws and hinges should be avoided to prevent unstable linkage. This is achieved by connecting the threaded rod 5 and threaded cylinder 6 within the linkage plate 8. The rotation of the threaded cylinder 6 moves the linkage plate 8 outwards. The movable locking block 4 engages with the connecting slot 3, ensuring a stable connection between the power distribution cabinets 1. A positioning component is provided. When the threaded rod 5 needs to be limited, the outward expansion of the linkage plate 8 drives the sliding seat 10 of the sliding rod 9 connected to the left to slide. This causes the linkage rod 13 outside the sliding seat 10 to rotate along the positioning shaft 11. At this time, the gear and threaded rod at the outer end of the positioning shaft 11 engage... The gear rings at the outer ends of rod 5 mesh with each other, thus ensuring linkage stability and limiting the threaded rod 5 under the setting of the sector groove 12; through the cooperation of the linkage component and the positioning component, it is easier to assemble the distribution cabinet 1 together stably; by setting the lifting component, when it is necessary to raise the assembled distribution cabinet 1 to avoid the bottom getting wet, the clamping plate 14 slides along the clamping rail 15, so that the lower end of the clamping plate 14 drives the spiral rod 25 to move inward, and the spiral rod 25 drives the bevel gear 23 to rotate. At this time, the bevel gear 23 drives the rotating rod 24 to rotate, and when the movable clamping block 4 slides, it drives the outermost protrusion 16 at the bottom to push the inclined plate 17 down, which can ensure that the two adjacent rotating rods 24 are stably engaged and connected, and rotate synchronously.

[0082] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
