[0025] As Figures 1 to 7As shown in the figure, a cascaded digital instrument related to the present invention includes an electric box 1. One side of the electric box 1 is movably connected with a glass door 2 through a first bolt. It should be noted that the electric box 1 is a conventional product of the prior art, and the screen on the control module 305 can be observed through the glass door 2. An assembly mechanism 3 is arranged inside the electric box 1; the assembly mechanism 3 includes a plurality of slide rails 301, a wiring unit 4 and a heat dissipation unit 5. The wiring unit 4 is fixedly connected to the assembly mechanism 3, and the heat dissipation unit 5 is fixedly connected to the electric box 1; a plurality of slide rails 301 are symmetrically fixedly connected to the inner walls on both sides of the electric box 1. A slider 302 is slidably connected inside each slide rail 301. A support panel 303 is fixedly connected among a plurality of sliders 302 through a first bolt. A plurality of detection modules 304 are fixedly connected to one side of the support panel 303 and are distributed in a square array. A control module 305 is fixedly connected to one side of the support panel 303. A plurality of circuit tracks 306 are symmetrically fixedly connected to the other side of the support panel 303. A rubber cylinder 307 is fixedly communicated with the other side of the support panel 303. By assembling and fitting the detection module 304 and the control module 305, the present invention realizes cascading multiple digital instruments, combines the measurement capabilities of multiple instruments, realizes a large range and higher detection accuracy and efficiency, and improves the system stability and reliability through the cascading method. At the same time, in the arrangement of connection lines, the connection lines are cross-wound by the winding frame 402 to keep the inside of the electric box 1 clean, so as to facilitate personnel observation and maintenance, which is beneficial to improving the reliability of the device. During the assembly, the detection module 304 and the control module 305 are respectively installed on one side of the support panel 303, and the circuit line 304a is placed inside the circuit track 306. The circuit line 304a is cross-wound with the winding frame 402 and passes through the pressure plate 409 to be connected to the control module 305. Among them, the circuit line 304a contacts the surface of the rubber cylinder 307. The rubber cylinder 307 has elastic deformation ability and a relatively soft surface, which can avoid abrasion with the circuit line 304a.

[0026] In an embodiment of the present invention, a through hole 303a is opened on one side of the support panel 303 and the through hole 303a corresponds to the position of the control module 305. A circuit line 304a is fixedly connected to one side of each detection module 304 and the circuit line 304a is fixedly connected to the control module 305. It should be noted that the detection module 304 is a conventional electric meter device of the prior art. The control module 305 receives the electric meter data, performs calculations, processing and decisions according to these data, and a screen is set on the control module 305, and the information generated by multiple electric meters can be digitally processed and displayed on the screen for users or maintenance personnel to observe, etc.

[0027] In an embodiment of the present invention, the wiring unit 4 includes a plurality of sliding grooves 401 which are respectively formed on the inner walls of both sides of the circuit track 306. A winding frame 402 is movably connected by a first insertion rod on the opposite sides of every two sliding grooves 401. It should be noted that during installation, the circuit wire 304a is cross-wound through the winding frame 402 to wind up the redundant circuit wire 304a. During maintenance, due to the tension received by the circuit wire 304a, the winding frame 402 moves and rotates to one side, avoiding wire chaos and simplifying the maintenance steps. A first spring 403 is fixedly connected to the inner wall of the top of each sliding groove 401. The first spring 403 is movably connected to the first insertion rod through a collar 404. A plurality of limiting frames 405 are fixedly connected to one side of the support panel 303 and the limiting frames 405 correspond to the positions of the sliding grooves 401. A limiting block 406 is slidably connected inside each limiting frame 405 and the limiting block 406 is movably connected to the first insertion rod through a first bearing. A first telescopic rod 407 is fixedly connected to the inner wall of the top of the limiting frame 405 and the first telescopic rod 407 is fixedly connected to the limiting block 406. First torsion springs 408 are respectively movably sleeved on both ends of the first insertion rod and both ends of the first torsion springs 408 are respectively fixedly connected to one side of the limiting block 406 and the side surface of the first insertion rod. Pressing plates 409 are fixedly connected to the inner walls of both sides of each circuit track 306. It should be noted that by providing the pressing plates 409, during use, one end of the circuit wire 304a is pressed by the pressing plates 409 to prevent the circuit wire 304a from being pulled and disconnected from the control module 305 during the disassembly of the detection module 304 during maintenance. By providing the winding frame 402 in the present invention, during the maintenance of the detection module 304, a pulling force is applied to the connection wires on the detection module 304. The winding frame 402 can keep the connection wires in two states of loose and tight, which is beneficial to improving the maintenance efficiency. When maintenance is required, first remove the bolts on the detection module 304 with tools and take it out from the support panel 303. During this process, the movement of the detection module 304 applies a pulling force to the circuit wire 304a, increasing the tension of the circuit wire 304a, driving the winding frame 402 to move to one side in the sliding groove 401 and rotate, and winding out the circuit wire 304a wound on the winding frame 402, facilitating the maintenance by the staff. During installation, the detection module 304 is installed on the support panel 303 with tools. Since the limiting block 406 is movably connected to the first telescopic rod 407, the first torsion spring 408 generates a torque as the winding frame 402 rotates. The first torsion spring 408 drives the winding frame 402 to rotate in the opposite direction to wind up the circuit wire 304a to prevent it from becoming loose and chaotic. By tightly pressing one end of the circuit wire 304a with the pressing plate 409, it can be avoided that the circuit wire 304a is disconnected from the control module 305 due to the pulling force on the circuit wire 304a.

[0028] As another embodiment of the present invention, the heat dissipation unit 5 includes a support frame 501, the support frame 501 is fixedly connected to the bottom of the electric box 1, a fixed cylinder 502 is fixedly communicated with the bottom of the electric box 1 and the fixed cylinder 502 is fixedly sleeved on the inner wall of the support frame 501, the bottom of the fixed cylinder 502 is fixedly communicated with a disassembly and assembly cylinder 503 through a first thread. It should be noted that the disassembly and assembly cylinder 503 is threadedly connected to the fixed cylinder 502, which is more convenient when repairing or replacing the filter element 504. And by arranging a plurality of flow ports on the side surface of the disassembly and assembly cylinder 503, the hot air flow can be completely discharged. A filter element 504 is fixedly sleeved on the inner wall of the fixed cylinder 502 and the filter element 504 is in movable contact with the disassembly and assembly cylinder 503. It should be noted that the filter element 504 is a conventional device in the prior art. During use, a first motor 505 drives a fan blade 506 to extract the air inside the electric box 1. Among them, through the air flow, the dust in the gas can be inhaled into the filter element 504, and through the air flow, the heat inside the electric box 1 is dissipated along with the air flow. A first motor 505 is fixedly sleeved on the inner wall of the disassembly and assembly cylinder 503, and the output end of the first motor 505 is fixedly connected to a fan blade 506. By setting the filter element 504 in the present invention, the flowing gas can be dust-removed, and by rotating the fan blade 506, the fluid inside the electric box 1 is circulated to discharge the heat inside it, which is beneficial to improving the stability inside the electric box 1. During long-term use, an external circuit mechanism enables the first motor 505 to drive the fan blade 506 to rotate, the air inside the electric box 1 flows, and dust is mixed into the fixed cylinder 502. After passing through the filter element 504, it can prevent the dust from flowing into the external air and affecting the environment. Among them, through the gas flow, the heat dissipation function inside the electric box 1 can be realized, avoiding dust accumulation during long-term use and affecting the use of the detection module 304.

[0029] Working principle: This embodiment provides a cascaded digital instrument. During assembly, first install the detection module 304 and the control module 305 on one side of the support panel 303 respectively, and place the circuit wire 304a inside the circuit track 306. The circuit wire 304a is cross-wound with the winding frame 402 and passes through the wire pressing plate 409 to be connected to the control module 305. Among them, the circuit wire 304a contacts the surface of the rubber cylinder 307. The rubber cylinder 307 has elastic deformation ability and a relatively soft surface, which can avoid abrasion with the circuit wire 304a. When maintenance is required, first remove the bolts on the detection module 304 with tools and take it out from the support panel 303. During this process, the movement of the detection module 304 exerts a pulling force on the circuit wire 304a, increasing the tension of the circuit wire 304a, driving the winding frame 402 to move to one side in the sliding groove 401 and rotate, and winding out the circuit wire 304a wound on the winding frame 402, facilitating maintenance by the staff. During installation, install the detection module 304 on the support panel 303 with tools. Since the limit block 406 is movably connected to the first telescopic rod 407, the first torsion spring 408 generates torque as the winding frame 402 rotates. The first torsion spring 408 drives the winding frame 402 to rotate in the opposite direction to wind the circuit wire 304a and make it wind up, preventing loose and chaotic phenomena. Among them, one end of the circuit wire 304a is tightly pressed by the wire pressing plate 409, which can avoid the circuit wire 304a being disconnected from the control module 305 due to the pulling force. During long-term use, the first motor 505 drives the fan blade 506 to rotate through an external circuit mechanism, and the air inside the electric box 1 flows and dust is mixed into the fixed cylinder 502. After passing through the filter element 504, it can prevent dust from flowing into the external air and affecting the environment. Among them, through the air circulation, the heat dissipation function inside the electric box 1 can be realized, avoiding dust accumulation during long-term use and affecting the use of the detection module 304.
