[0002] In the field of power distribution cabinet technology, the internal mounting panels of traditional power distribution cabinets are mostly fixed structures or can only be adjusted to a limited extent using bolts, slots, etc. The adjustment process requires manual disassembly or re-fixing, which is cumbersome and inefficient. At the same time, existing adjustable internal panels often cannot achieve independent and precise adjustment of one or more internal panels, and cannot flexibly adapt to the installation height requirements of different specifications of electrical components. This results in low utilization of the internal space of the cabinet, and the adjustment process can easily interfere with the already installed components. The adaptability and practicality need to be improved. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an adjustable inner panel power distribution cabinet, including a cabinet body and a cabinet door that is movably hinged to the cabinet body. The cabinet body has several parallel inner panels.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] like Figure 1-4 The diagram shows an adjustable inner panel 3 type power distribution cabinet, including a cabinet body 1 and a cabinet door 2 that is movably hinged to the cabinet body 1. The cabinet body 1 has several parallel inner panels 3 inside. The inner walls of the cabinet body 1 on both sides of the inner panels 3 are provided with drive plates 4 protruding towards the inside of the cabinet body 1. The protruding side of the drive plate 4 forms a drive chamber 5 between itself and the inner wall of the cabinet body 1. The drive chambers 5 on both sides are provided with vertically extending transmission rods 6. The same number of coupling mechanisms 7 as the inner panels 3 are sleeved on the outside of the transmission rods 6. The outer wall of the drive plate 4 facing the inner panel 3 has a through connecting groove 8. Adjusting components 9 are fixedly installed on the surfaces of the edges on both sides of the inner panel 3. The adjusting components 9 extend into the drive chamber 5 through the connecting groove 8 to limit the coupling mechanism 7. The top of the transmission rod 6 extends through the cabinet body 1 to the top of the cabinet body 1. A drive component 94 connected to the top of the drive rod is installed on the top of the cabinet body 1. The drive component 94 drives the coupling mechanism 7 and the adjusting component 9 through the drive rod to drive the inner panel 3 to adjust its height.

[0020] Based on the above, in actual operation, the drive chamber 5 provides an independent protective space for the transmission components, avoiding mutual interference between the internal electrical components and the transmission structure; the connecting groove 8 provides an active channel for the adjusting component 9 and the connecting block 74, and also restricts their lateral displacement, ensuring that the inner plate 3 is adjusted only in the vertical direction. The overall structure is compact and the functional zoning is clear, which improves the stability of the equipment operation.

[0021] The outer wall of the transmission rod 6 is provided with threads that cooperate with the coupling mechanism 7, and the threads of the two drive rods are in opposite directions.

[0022] Based on the above, the threaded connection enables precise power transmission between the transmission rod 6 and the coupling mechanism 7, ensuring that the coupling mechanism 7 can move up and down stably along the axial direction of the transmission rod 6. The design of opposite thread directions on both sides of the transmission rod 6 can make the forces on both sides of the inner plate 3 balanced, avoiding tilting or jamming of the inner plate 3 due to excessive force on one side, thus ensuring the smoothness of the adjustment process.

[0023] The adjusting component 9 includes a miniature push rod 91 fixed to the surface of the inner plate 3. A limiting rod 92 that cooperates with the coupling mechanism 7 is fixedly installed at the output shaft end of the miniature push rod 91. A protective cover 93 fixed to the surface of the inner plate 3 is provided on the outside of the miniature push rod 91.

[0024] Based on the above, the miniature push rod 91 can flexibly control the extension and retraction of the limit lever 92, and achieve selective limiting of a specific coupling mechanism 7, thereby accurately controlling the adjustment state of one or more inner plates 3; the protective cover 93 can effectively block dust, water vapor and debris generated by electrical components during operation inside the cabinet 1, protect the miniature push rod 91 from corrosion, extend the service life of the adjusting part 9, and ensure the reliability of long-term operation.

[0025] The coupling mechanism 7 includes a screw tube 71, a sleeve 72 and a first bearing 73 sleeved on the outside of the drive rod. The screw tube 71 is threaded to the outer wall of the drive rod. The sleeve 72 is fixed to the bottom end of the screw tube 71. The inner ring of the first bearing 73 is fixed to the inner end of the screw tube 71. The inner wall of the inner ring of the first bearing 73 does not contact the outer wall of the drive rod.

[0026] Based on the above, the threaded engagement between the solenoid 71 and the transmission rod 6 can convert rotational motion into linear motion, thereby achieving the lifting and lowering of the inner plate 3. The non-contact design between the inner ring of the first bearing 73 and the transmission rod 6 reduces frictional losses between the coupling mechanism 7 and the transmission rod 6. At the same time, the sleeve 72 provides support to the bottom of the solenoid 71, enhancing the overall structural strength of the coupling mechanism 7, preventing the solenoid 71 from deforming due to excessive force, and improving transmission efficiency and component durability.

[0027] A connecting block 74 is fixed on the outer wall of the outer ring of the first bearing 73. The connecting block 74 passes through the connecting groove 8 and is fixed at the edges on both sides of the inner plate 3. A limiting groove 76 recessed inward is provided on the outer wall of the screw tube 71. The adjusting member 9 extends into the limiting groove 76 to limit the screw tube 71.

[0028] Based on the above, the connecting block 74 passes through the connecting groove 8 to achieve a rigid connection between the coupling mechanism 7 and the inner plate 3, ensuring that the lifting of the coupling mechanism 7 can directly drive the inner plate 3 to move synchronously; the cooperation between the limiting groove 76 and the adjusting member 9 forms a precise limiting structure. When the adjusting member 9 extends into the limiting groove 76, it can firmly lock the screw tube 71 to prevent it from spinning freely, ensuring that the power is efficiently transmitted to the inner plate 3. The separation state when no adjustment is needed can also prevent the inner plate 3 from moving erroneously, thus improving the controllability of adjustment.

[0029] The drive rod is also fitted with a second bearing 11 to limit the drive rod inside the cabinet 1. The second bearing 11 is fixed to the top and bottom of the inner cavity of the cabinet 1. The second bearing 11 provides upper and lower fixed support for the drive rod, effectively limiting the radial sway of the drive rod during rotation, avoiding thread transmission jamming or component collision caused by drive rod offset, ensuring the stability and concentricity of the rotation of the drive rod 6, and providing a basic guarantee for the precise adjustment of the inner panel 3.

[0030] Two limiting plates 12 are provided on each side edge of the inner plate 3, clamping the edge of the drive plate 4. The limiting plates 12 are perpendicular to the upper and lower surfaces of the inner plate 3. The outer wall of the limiting plate 12 facing the drive plate 4 is embedded with a ball bearing 13 that fits against the drive plate 4. The structure of the limiting plate 12 clamping the drive plate 4 can restrict the lateral displacement of the inner plate 3 from both sides, preventing the inner plate 3 from shifting or tilting during the lifting and lowering process. The fit between the ball bearing 13 and the drive plate 4 converts sliding friction into rolling friction, which greatly reduces the resistance when the inner plate 3 is lifted and lowered, making the adjustment process smoother. At the same time, it reduces the wear of the limiting plate 12 and the drive plate 4, and extends the service life of the components.

[0031] The drive component 94 includes a dual-axis servo motor 101 fixed to the top of the cabinet 1. The two output shafts of the dual-axis servo motor 101 are each equipped with a first helical gear 102. The top of the transmission rod 6 is equipped with a second helical gear 103 that meshes with the first helical gear 102.

[0032] Based on the above, the dual-axis servo motor 101 can simultaneously provide power to the two transmission rods 6. Through helical gear meshing, it not only has high transmission efficiency and low power loss, but also ensures the synchronous rotation of the two transmission rods 6, avoiding the inner plate 3 from tilting due to asynchronous power on both sides. The precise control characteristics of the servo motor can realize the precise adjustment of the lifting height of the inner plate 3, meet the installation accuracy requirements of different electrical components, and improve the automation control level of the equipment.

[0033] Based on the above, the dual-axis servo motor 101 at the top of the cabinet 1 serves as the power source. Its output shaft meshes with the second helical gear 103 at the top of the transmission rod 6 through the first helical gear 102, driving the vertically extending transmission rods 6 on both sides to rotate synchronously. The outer wall of the transmission rod 6 is threaded, and the thread directions of the two transmission rods 6 are opposite. In the coupling mechanism 7 sleeved outside the transmission rod 6, the screw tube 71 is threaded with the transmission rod 6. When the transmission rod 6 rotates, the screw tube 71 can move up and down along the axial direction of the transmission rod 6. The coupling mechanism 7 is connected to the inner plate 3 through the connecting block 74 on the outer ring of the first bearing 73, forming a linkage chain of "transmission rod 6-coupling mechanism 7-inner plate 3". The adjusting parts 9 on both sides of the inner plate 3 extend into the drive chamber 5 through the connecting groove 8 and cooperate with the screw tube 71 of the coupling mechanism 7 to achieve limit positioning. When it is necessary to adjust a certain inner plate 3, the micro push rod 91 pushes the limit lever 92 to extend into the limit groove 76 on the outer wall of the screw tube 71, so that the screw tube 71 cannot rotate independently, but can only rise and fall with the rotation of the transmission rod 6, and then drives the inner plate 3 to rise and fall synchronously through the connecting block 74; if no adjustment is needed, the micro push rod 91 retracts the limit lever 92, the screw tube 71 can rotate freely, and the inner plate 3 remains stationary.

[0034] The miniature push rods 91 are connected in parallel circuits, with each miniature push rod 91 corresponding to an independent control circuit. Each circuit includes a control switch to achieve individual or combined control. By switching the control switches on and off, the output shaft of the miniature push rod 91 is driven to extend or retract, causing the limit lever 92 to selectively extend into or retract from the limit groove 76 of the solenoid 71. The parallel connection and independent control circuit design of the miniature push rods 91 are common and mature technologies in the field of electrical control, and are conventional structures familiar to those skilled in the art, requiring no further detailed description for understanding and implementation.

[0035] Furthermore, the adjustment component 9 and the coupling mechanism 7 can achieve independent lifting of one or more inner plates 3 to adapt to different installation requirements. The reverse threads of the transmission rods 6 on both sides, in conjunction with the limit plate 12 and the ball bearings 13, can ensure that the inner plates 3 are subjected to balanced force and that the lifting is smooth and without deviation. The dual-axis servo motor 101 achieves precise adjustment through gear transmission. The protective cover 93 and the non-contact design of the bearings reduce component wear and extend service life. The overall structure is compact and easy to operate, and can efficiently meet the installation requirements of various electrical components.

[0036] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
