[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] In one embodiment, see Figure 1, a pull-out recovery type switchboard structure is provided, including a switchboard main cabinet 10 and an external frame 21 provided with a side edge of the switchboard main cabinet 10; a switchboard carrier 11 is provided on the load surface of the switchboard main cabinet 10, the switchboard carrier 11 is provided with a pull-out portion 12, and a load circuit breaker 13 and a load connector 14 are also provided on the switchboard carrier 11, the pull-out portion 12 is slidably installed on the switchboard carrier 11, and the electric contact end of the load circuit breaker 13 and the electric contact end of the load connector 14 are both in contact with the electric contact panel of the pull-out portion 12 ; An electrical component mounting frame 15 is also provided on the load surface of the main cabinet 10 of the distribution board, and an electrical component docking carrier 16 is provided on the electrical component mounting frame 15, and the electrical component docking carrier 16 is slidably installed on the electrical component mounting frame 15 and is connected to the electric touch panel of the pull-out part 12; a pull-out belt 17 is externally connected to the end of the pull-out part 12, and a pull-out transmission member 22 is provided on the external frame 21, and 23 is also provided on the distribution board carrier 11, and the pull-out belt 17 is mounted on 23 and is connected to the traction end of the pull-out transmission member 22.

[0030] The main cabinet 10 of the switchboard is made of solid metal material to ensure its structural strength and electrical safety. The switchboard carrier 11 is the main bearing component, and the pull-out part 12 is made of durable plastic or insulating material. An electric touch panel is embedded on its surface. A plurality of electrical contacts are distributed on the panel for establishing electrical connection with the load circuit breaker 13 and the load connector 14. The load circuit breaker 13 usually includes a circuit breaker, which is used to automatically cut off the power supply when the circuit is overloaded or short-circuited to protect the safety of the circuit and equipment. The load connector 14 provides a connection interface with an external load (such as a motor, lighting equipment, etc.). The electrical contact ends of these two types of components are designed to be pluggable, which facilitates fast and reliable electrical connection with the electric touch panel of the pull-out part 12. The electrical component mounting frame 15 is located on one side of the switchboard carrier 11 and is used to install various control electrical components, such as relays, contactors, etc. The electrical component docking carrier 16 is designed to match the shape and size of these electrical components, and can slide along the electrical component mounting frame 15, so as to adjust its position to dock with the electric touch panel of the drawer 12, so as to realize complex electrical control logic. The end of the drawer 12 is externally connected with a flexible drawer belt 17, which is made of high-strength, wear-resistant nylon material to ensure that it is not easy to break during long-term use. The drawer transmission member 22 on the external frame 21 controls its movement to achieve smooth and precise pulling of the drawer 12. A guide member 23 is also provided on the switchboard carrier 11, which is used to support and guide the movement path of the drawer belt 17, to ensure that the drawer belt 17 can be smoothly mounted thereon and reliably connected to the traction end of the drawer transmission member 22.

[0031] By adjusting the position of the drawer 12, the load connector 14 is connected to different circuit connection points on the drawer 12, thereby realizing flexible configuration of the circuit connection. This design enables the switchboard to adapt to a variety of different electrical layout requirements, improving its versatility and adaptability. This pull-out design makes the replacement and maintenance of key components such as the load circuit breaker 13, the load connector 14, and the electrical component docking carrier 16 simpler and more convenient. When it is necessary to upgrade or replace electrical components, it is only necessary to unfasten the drawer belt 17 and slide the relevant components without complicated disassembly work. By designing components such as the electrical component mounting frame 15 and the drawer 12 to be slidable, the space inside the switchboard is more effectively utilized.

[0032] In one embodiment, see Figure 1 and Figure 2 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the switchboard carrier 11 is designed as follows:

[0033] The distribution board carrier 11 includes a carrier surface 81 and a carrier mounting groove 82 arranged on the carrier surface 81. The main body of the pull-out part 12 is an electrical substrate 83, which is slidably installed on the carrier mounting groove 82 and is provided with a plurality of contact terminals 86. An elastic reset joint 85 is provided at the groove end of the carrier mounting groove 82. One end of the electrical substrate 83 is connected to the elastic reset joint 85, and the other end of the electrical substrate 83 is provided with a pull-out head 84, and the pull-out belt 17 is installed on the pull-out head 84. The load circuit breaker 13 and the load connector 14 are both arranged on the platform surface 81. The load circuit breaker 13 includes a power supply device 31, an electrical connection terminal 32 arranged on the power supply device 31, and a circuit breaker head 33 installed on the electrical connection terminal 32; the load connector 14 includes a line connection frame 34 and a terminal connector 36 installed on the line connection frame 34. The circuit breaker head 33 and the terminal connector 36 are both electrically connected to the contact terminal 86.

[0034] The table top 81 of the carrier is made of high-strength insulating material to ensure the safe isolation of electrical components. The table top is flat and smooth, which is convenient for the arrangement and installation of electrical components. The carrier mounting groove 82 is designed as a slide rail structure that matches the electric connection substrate 83 to ensure that the electric connection substrate 83 can slide steadily and smoothly. As the main body of the pull-out portion 12, the electric connection substrate 83 is made of high-quality copper alloy material and has good electrical conductivity and mechanical strength. There are several contact terminals 86 distributed on its surface, and these contact terminals 86 are treated with a gold plating process to improve the reliability and stability of the electrical connection. One end of the electric connection substrate 83 is connected to the groove end of the carrier mounting groove 82 through an elastic reset joint 85. The elastic reset joint 85 adopts a spring structure, which can provide a certain damping and reset force when the electric connection substrate 83 slides, ensuring that the electric connection substrate 83 can remain stable at any position. The pull-out head 84 is designed as a hook structure that matches the pull-out belt 17, which is convenient for the installation and removal of the pull-out belt 17. The draw-out belt 17 is made of high-strength, wear-resistant nylon material to ensure that it is not easy to break during long-term use. Through the connection of the draw-out belt 17 and the draw-out transmission member 22, control and regulation of the electric connection base plate 83 can be realized.

[0035] The power supply device 31 of the load circuit breaker 13 usually adopts an electrical protection element such as a circuit breaker or a fuse, which is used to automatically cut off the power supply when the circuit is overloaded or short-circuited. The electrical connection terminal 32 is designed as a socket structure that matches the circuit breaker 33, which is convenient for plugging and unplugging and connecting the circuit breaker 33. The circuit breaker 33 is made of high-quality copper alloy material and has good electrical conductivity and mechanical strength. The line connection frame 34 of the load connector 14 is designed as a bracket structure that matches the terminal connector 36. The adjustment frame 35 that supports the line connection frame 34 is arranged on the platform table 81, which is convenient for fixing and connecting the terminal connector 36. The terminal connector 36 is made of tinned copper sheet, which has good electrical conductivity and corrosion resistance. Through the electrical connection between the circuit breaker 33 and the terminal connector 36 and the contact terminal 86, the power supply and control of the load can be realized.

[0036] In one embodiment, see Figure 1 and Figure 3 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the pull-out transmission member 22 is designed as follows:

[0037] The main body of the external frame 21 is a vertical support frame 41, and the pull-out transmission member 22 includes a pull-out turntable 42 and a reset turntable 43, and the pull-out turntable 42 and the reset turntable 43 are distributed and installed in the upper and lower positions of the vertical support frame 41. The pull-out transmission member 22 also includes a positioning slide 44, and the positioning slide 44 is arranged between the pull-out turntable 42 and the reset turntable 43; the positioning slide 44 is provided with an adjustment track 45 and a medium rod 46 slidably installed on the adjustment track 45, and the groove of the adjustment track 45 is provided with a photosensitive scale, and the pull-out turntable 42 and the reset turntable 43 are both installed with traction belts on the disk body, the traction belt of the pull-out turntable 42 is connected to the medium rod 46 and drives the medium rod 46 to move forward, the traction belt of the reset turntable 43 is connected to the medium rod 46 and drives the medium rod 46 to move backward, and the end of the pull-out belt 17 is fixedly connected to the medium rod 46.

[0038] The main body of the external frame 21 is a vertical support frame 41, which is made of a solid metal material and has sufficient strength and stability to support the main cabinet 10 of the distribution board and its related components. The pull-out transmission member 22 includes a pull-out turntable 42 and a reset turntable 43, which are respectively installed at the upper and lower positions of the vertical support frame 41. The pull-out turntable 42 is used to provide a forward pulling force, while the reset turntable 43 is used to provide a backward reset force. This design enables the pull-out part 12 to move smoothly in two directions. The media rod 46 is slidably installed on the adjustment track 45 and serves as a connecting medium between the pull-out transmission member 22 and the pull-out belt 17. The adjustment track 45 is used to guide the sliding of the media rod 46. At the notch of the adjustment track 45, a photosensitive scale is provided, which can detect the position of the media rod 46 and transmit the position information to the control system through a photoelectric signal to achieve precise pull-out control.

[0039] This embodiment can realize accurate detection and control of the position of the medium rod 46 through the design of the photosensitive scale and the adjustment track 45. This enables the pull-out portion 12 to be quickly and accurately moved to the specified position when needed, improving the flexibility and configurability of the switchboard. The design of the pull-out turntable 42 and the reset turntable 43 enables the pull-out portion 12 to move smoothly in two directions, avoiding electrical connection problems caused by shaking or instability during the pull-out process. At the same time, the connection method of the traction belt and the medium rod 46 also ensures the stability and reliability of the pull-out force.

[0040] In one embodiment, see Figure 1 , Figure 4 and Figure 5 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the electrical component mounting frame 15 and the electrical component docking carrier 16 is designed as follows:

[0041] The electrical component mounting frame 15 includes a vertical carrier frame 51, a sliding base 52 installed on the bottom end of the vertical carrier frame 51, and a sliding track 53 arranged on the sliding base 52. The electrical component docking carrier 16 is vertically arranged on the plate body of the vertical carrier frame 51, and the bottom end of the electrical component docking carrier 16 is slidably installed on the sliding track 53; the side end of the sliding base 52 is also provided with a side support plate 55 and a pusher 56 installed on the side support plate 55, and the pusher 56 is provided with a movable push rod 57. The bottom of the electrical component docking carrier 16 is provided with a through rod block 54, and the rod end of the movable push rod 57 is installed on the through rod block 54.

[0042] The vertical carrier frame 51, as the main body of the electrical device mounting frame 15, is made of high-strength, corrosion-resistant metal materials to ensure the stability and durability of the overall structure. The plate body of the vertical carrier frame 51 is designed with a vertically arranged electrical device docking carrier 16 installation position, and the sliding base 52 is firmly installed at the bottom of the vertical carrier frame 51 to provide stable support for the sliding of the electrical device docking carrier 16. The sliding track 53 is cleverly arranged on the sliding base 52, adjacent to the side edge of the electrical connection substrate 83 (the main body of the pull-out part 12), ensuring that the electrical device docking carrier 16 can accurately and smoothly contact and dock with the electrical connection substrate 83 during the sliding process. The displacement of the electrical device docking carrier 16 cooperates with the displacement of the pull-out part 12 (electrical connection substrate 83). When the pull-out part 12 is pulled out or reset, the electrical device docking carrier 16 can move synchronously to ensure that the electrical device and the contact terminal 86 on the electrical connection substrate 83 always maintain a good electrical connection. This design not only improves the reliability of electrical connection, but also makes the installation and removal of electrical components more convenient.

[0043] Through the design of the sliding base 52 and the sliding rail 53, the electrical device docking carrier 16 can easily slide on the vertical carrier frame 51 to achieve rapid installation and removal of electrical devices. This not only saves installation time, but also reduces installation difficulty and improves work efficiency; the contact docking design of the electrical device docking carrier 16 and the electrical connection substrate 83 ensures a good electrical connection between the electrical device and the internal circuit of the switchboard. At the same time, through the displacement coordination of the electrical device docking carrier 16 and the pull-out portion 12, the stability and reliability of the electrical connection are further improved.

[0044] The electrical component docking carrier 16 includes an upper mounting frame 61 and a lower hidden frame 65. The lower hidden frame 65 is arranged at the bottom of the upper mounting frame 61. The upper mounting frame 61 is provided with a component mounting groove 62. The lower hidden frame 65 is provided with a component hidden groove 66. The component mounting groove 62 and the component hidden groove 66 are connected. A hanging rack 63 is arranged in the component mounting groove 62. An inner groove track 64 is arranged on the hanging rack 63. A plurality of electrical group connecting components 60 are installed on the hanging rack 63 through the inner groove track 64. The track terminal of the inner groove track 64 guides to the component hidden groove 66.

[0045] The electrical equipment group connection element 60 is connected to the same group of electrical equipment in the same system through electric wires, and is an electrical connection tool for the same group of electrical equipment. The upper mounting frame 61 and the lower hidden frame 65 are combined into a vertical channel. The upper mounting frame 61 serves as the main display and operation platform of the electrical equipment group connection element 60. The upper mounting frame 61 is designed with a component installation groove 62, which not only provides sufficient space for the installation of the electrical equipment group connection element 60, but also ensures the convenience of operation. The opening design of the component installation groove 62 facilitates the insertion, adjustment and removal of components by technicians. The lower hidden frame 65 is located at the bottom of the upper mounting frame 61, and its main function is to provide a hidden storage space. The component hidden groove 66 is connected to the component installation groove 62 through an internal channel, ensuring that the components can be smoothly transferred between the two areas. The inner groove track 64 is a guiding structure for the movement of the electrical equipment group connection element 60.

[0046] In the initial state, the electrical group connection element 60 is connected to the same group of electrical equipment in the same system through wires, and is located in the element installation slot 62 of the upper mounting frame 61, ready for electrical connection. When a certain electrical group connection element 60 needs to be replaced or maintained, the technician can slide it along the inner groove track 64 to the element hidden slot 66 of the lower hidden frame 65. At the same time, the upper electrical group connection element 60 automatically descends to the original position and docks with the electrical connection substrate 83 to keep the circuit unobstructed. After the replacement is completed, the new or repaired electrical group connection element 60 can be taken out of the hidden slot and relocated to the installation slot along the track.

[0047] The combination design of the upper mounting frame 61 and the lower hidden frame 65 realizes the three-dimensional storage and display of electrical components, effectively saving the space inside the switchboard and improving the space utilization rate. The design of the movement of the electrical group connecting element 60 along the inner groove track 64 makes the replacement and adjustment of the components more flexible and convenient, reduces the maintenance cost and improves the work efficiency. The design of this electrical component docking carrier 16 not only optimizes the structural layout of the switchboard, but also improves the operation efficiency and safety.

[0048] In one case of this embodiment, see Figure 6The present embodiment also discloses an implementation structure of an electrical group connection element 60, wherein the electrical group connection element 60 includes a main support plate 71 and a lower support plate frame 72, wherein the main support plate 71 and the lower support plate frame 72 are assembled and the lower support plate frame 72 is located below the main support plate 71, wherein a plurality of connector mounting strips 73 are arranged on the main support plate 71, and a plurality of electrical connection slots 74 are arranged on the lower support plate frame 72, wherein the connector mounting strips 73 are matched one by one with the electrical connection slots 74 and are inserted into the electrical connection slots 74, wherein a plurality of crimping type gear connectors 75 are arranged in the electrical connection slots 74, wherein an electrical group connector 76 is arranged at the bottom end of the crimping type gear connector 75, and a support bottom plate 77 is arranged at the bottom of the main support plate 71, wherein the support bottom plate 77 blocks the bottom of the electrical group connector 76.

[0049] This embodiment achieves high reliability and stability of electrical connection through the coordinated use of the connector mounting strip 73, the electrical connection slot 74 and the crimping type gear connector 75. The various components of the electrical group connection element 60 are reasonably designed and easy to disassemble and replace, which reduces maintenance costs and time. The design of the support bottom plate 77 prevents the electrical group connector 76 from being damaged or interfered by the outside, thereby improving the safety of the entire electrical group connection element 60. The electrical group connection element 60 has a compact structure and a small size, which is convenient for layout and installation in the distribution board, thereby improving space utilization.
