[0030] like Figure 1-5 As shown, an embodiment of the present invention provides a line isolator for a distribution cabinet, comprising a fixedly connected mounting plate 1 and an isolation box 2, wherein a plurality of isolation plates 3 are fixedly installed inside the isolation box 2, and three cable grooves 4 are provided on the isolation plate 3. A protective cover 5 is slidably connected to one side of the isolation box 2, and square grooves 8 are provided on both sides of the mounting plate 1. A square block 9 is movably passed through the interior of the square groove 8, and threaded rods 10 are fixedly connected on both sides of the block 9. The outer wall of the threaded rod 10 is threadedly connected to a threaded ring 11, and three cable holes are provided through the isolation box 2.
[0031] When using the device to isolate the lines inside the distribution cabinet, pass the wires through the cable holes and pass the wires through the cable troughs 4 during the threading process. The isolation plates 3 and the cable troughs 4 support the wires. Then, slide the protective cover 5 to close the isolation box 2. When isolating and fixing longer wires, fit one side of the two mounting plates 1 together, pass the block 9 through the inside of the square groove 8, and use the threaded rings 11 at both ends of the block 9 to be threadedly connected to the threaded rod 10, thereby fixing the two isolation plates 3 and fixing and supporting the long wires. When the wires are bent vertically, When arranging, place the mounting plate 1 vertically, use the block 9 to fix the two mounting plates 1, so that the two isolation boxes 2 are arranged vertically. By setting the mounting plate 1 and isolation box 2 that can be assembled and used, the appropriate number of isolation boxes 2 can be selected according to the length of the wire, and the mounting plate 1 is used for fixed arrangement to avoid the use of isolators in the middle of the wire, which will cause the wires on both sides to bend due to gravity, thereby avoiding damage and aging of the connection. In addition, the isolation box 2 can be fixed and used in combination vertically to adapt to the bending of right-angle wiring and isolate and fix wires with different arrangements.
[0032] like Figure 3 As shown, an iron sheet 6 is fixedly connected to the inner wall of the isolation box 2, and a magnetic sheet 7 is fixedly connected to one side of the protective cover 5. The iron sheet 6 and the magnetic sheet 7 attract each other. By setting the iron sheet 6 and the magnetic sheet 7, the opening and closing of the isolation box 2 and the protective cover 5 are facilitated, and the internal wires of the isolation box 2 are facilitated to be repaired.
[0033] like Figure 1 and Figure 2As shown, one side of the thread ring 11 contacts one side of the mounting plate 1 , thereby enabling the square groove 8 to fix the two mounting plates 1 .
[0034] like Figure 4 and Figure 5 As shown, the inner middle section of the mounting plate 1 is fixedly connected to the limit seat 13, and a limit groove 14 is provided inside the limit seat 13. The inner movement of the limit groove 14 passes through the limit rod 15, and the bottom of the limit rod 15 is fixedly connected with a threaded column 16. The outer wall of the threaded column 16 is threadedly connected to the inner wall of the limit seat 13. The outer wall of the limit rod 15 is fixedly connected with three groups of limit rings 17, and a connecting plate 18 is rotatably connected between each group of limit rings 17. One side of the connecting plate 18 is fixedly connected to the limit plate 19, and one side of the limit seat 13 is fixedly connected with a fixed plate 20.
[0035] Pass the wires through the cable tray 4, rotate the limit rod 15 to make the threaded column 16 rotate inside the limit seat 13 and move in the vertical direction, the limit rod 15 drives the three sets of limit rings 17 to rotate inside the limit groove 14, and the vertical position of the limit ring 17 drives the connecting plate 18 to move in the vertical direction to fix the wires on the top of the fixed plate 20. By setting the fixed plate 20 and the movable limit plate 19, the wires are fixed, thereby preventing the connection ends from being twisted and damaged due to the movement of the wires.
[0036] like Figure 5 As shown, a rotating handle 21 is fixedly connected to the top of the limiting rod 15 to facilitate the rotation of the limiting rod 15.
[0037] like Figure 1 and Figure 2 As shown, rubber rings 12 are fixedly connected to both sides of the isolation box 2. During the wiring process, the wires are passed through the rubber rings 12, and the rubber rings 12 scrape off the dust on the outer wall of the wires.
[0038] like Figure 2 As shown, the cable trough 4 is tilted on one side close to the protective cover 5 to prevent the wires from falling out of the cable trough 4 .
[0039] like Figure 5 As shown, a moving groove for limiting the moving direction of the connecting plate 18 is opened on one side of the limiting seat 13, so that the connecting plate 18 and the limiting plate 19 can only move in the vertical direction.
[0040] The technical solution provided by the present invention is that when using the device to isolate the lines inside the distribution cabinet, the wires are passed through the wire arrangement holes, and during the threading process, the wires are passed through the wire arrangement trough 4. The isolation plate 3 and the wire arrangement trough 4 support the wires, and then the sliding protective cover 5 closes the isolation box 2. When isolating and fixing longer wires, one side of the two mounting plates 1 is fitted together, and the block 9 is passed through the interior of the square groove 8. The two ends of the block 9 are threadedly connected to the threaded rod 10 using threaded rings 11, thereby achieving the fixation of the two isolation plates 3. To provide fixed support for long sections of wires, when the wires are arranged in a vertical bend, place the mounting plate 1 vertically, use block 9 to fix the two mounting plates 1, so that the two isolation boxes 2 are arranged vertically, pass the wires through the cable troughs 4, rotate the limit rod 15 to make the threaded column 16 rotate inside the limit seat 13 and move in the vertical direction, the limit rod 15 drives the three groups of limit rings 17 to rotate inside the limit groove 14, and the vertical position of the limit ring 17 drives the connecting plate 18 to move in the vertical direction to fix the wires on the top of the fixed plate 20.
[0041] The present invention encompasses any substitutions, modifications, equivalent methods, and solutions that are not within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.
[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
