[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 8 As shown, this utility model provides a plug-in assembly with a high and low switch cabinet, including a cabinet 1. Support frames 2 are fixedly installed on both the left and right sides inside the cabinet 1. An installation frame 3 is provided between the two sets of support frames 2. The outer wall of the support frame 2 is provided with a positioning groove 5. The left and right sides of the installation frame 3 are provided with a locking block 6. The positioning groove 5 and the locking block 6 are matched. The two sets of locking blocks 6 are provided with a fixing groove 7 inside. The outer wall of the installation frame 3 is provided with an installation groove 4.

[0028] The mounting bracket 3 has a transmission groove 8 inside, and a rotating disk 9 is rotatably installed inside the transmission groove 8. Two sets of movable plates 12 are movably installed inside the transmission groove 8, and the two sets of movable plates 12 are located on the left and right sides of the rotating disk 9. A connecting rod 10 is rotatably installed on the top of the rotating disk 9. There are two sets of connecting rods 10, and the other end of the two sets of connecting rods 10 is rotatably connected to the movable plate 12. A transmission rod 11 is fixedly installed on one end of each set of movable plates 12, and one end of the transmission rod 11 extends through the interior of the fixed groove 7.

[0029] When the device is put into use, the operator can install the mounting bracket 3 as needed. First, the operator aligns the locking blocks 6 and positioning grooves 5 at both ends of the mounting bracket 3. Then, the locking blocks 6 are inserted into the positioning grooves 5. At this time, the wedge 15 is compressed and retracted into the telescopic groove 14. After the mounting bracket 3 is installed, the telescopic groove 14 and the fixing groove 7 are aligned, allowing the wedge 15 to reset through the elastic potential energy of the first spring 16. The wedge 15 then enters the fixing groove 7, completing the fixing of the mounting bracket 3. When it is necessary to remove the mounting bracket 3, the operator... The operator rotates knob 13 counterclockwise. The rotation of knob 13 drives the rotating disk 9 to rotate. The rotation of the rotating disk 9 will push the two sets of movable plates 12 outward through the connecting rod 10. Further, the distance between the two sets of movable plates 12 increases, causing the two sets of transmission rods 11 to move outward. As the transmission rods 11 are displaced, they will squeeze the wedge 15, causing the wedge 15 to be stored inside the telescopic groove 14. At this time, the operator can pull out the mounting bracket 3 to disassemble it. After installation, the operator can install the electrical equipment on the mounting bracket 3 through the mounting groove 4, which makes it easy to plug in the wires.

[0030] The design of the positioning groove 5 and the locking block 6 facilitates the installation of the mounting bracket 3 by the staff. After the mounting bracket 3 is installed, the wedge 15 enters the interior of the fixing groove 7 to fix the mounting bracket 3. Then, the staff can rotate the knob 13 to make the transmission rod 11 press the wedge 15, and at this time the wedge 15 is stored inside the telescopic groove 14. Compared with the traditional device, this device, through the detachable design of the mounting bracket 3, makes it convenient for the staff to adjust the installation position of the mounting bracket 3 according to the electrical equipment to be installed, and at the same time, it is convenient for the staff to inspect and maintain the electrical equipment, reducing the workload.

[0031] The support frame 2 has a cable tray 27 on its front side. Both sets of support frames 2 have sockets 17 on their front sides. Each set of sockets 17 has a slot 18 at its bottom. The cable tray 27 has connecting blocks 19 that match the shape of the sockets 17 on its left and right sides. The connecting blocks 19 are movably installed inside the sockets 17. A pressure block 21 is movably installed inside the connecting blocks 19. One end of the pressure block 21 is elastically connected to the connecting block 19 by a second spring 20. The other end of the pressure block 21 abuts against the slot 18.

[0032] Before wiring, the operator can install the ribbon cable 27 according to the location of the electrical equipment. The operator aligns the connecting blocks 19 on the left and right sides of the ribbon cable 27 with the sockets 17. Then, while pressing the button 24, the operator inserts the connecting block 19 into the socket 17. As the button 24 is pressed, the pin 26 penetrates into the interior of the connecting block 19 and presses the slope surface 22 of the pressure block 21, causing the pressure block 21 to move upward into the interior of the connecting block 19. The connecting block 19 can then be inserted into the socket 17. After insertion, the operator releases the button 24. At this time, the button 24 is reset by the elastic potential energy of the third spring 25, and the pressure block 21 will be inserted downward into the slot 18 by the elasticity of the second spring 20, completing the installation.

[0033] The design of the two sets of second springs 20 on the rear side of the cable tray 27 and the slots 18 opened on the outer wall of the support frame 2 allows the operator to press the button 24 to move the pressure block 21 upward into the interior of the connecting block 19. When the button 24 is released, the pressure block 21 will be pushed downward into the slot 18 by the elasticity of the second spring 20. Compared with traditional devices, this device can set the cable tray 27 according to the installation position of the electrical equipment, effectively improving the wiring efficiency and reducing the workload.

[0034] Both sets of connecting rods 10 are rotatably mounted at the eccentric position of the rotating disk 9, and a knob 13 is fixedly mounted on the top of the rotating disk 9. The knob 13 is rotatably mounted on the top of the mounting bracket 3.

[0035] Since the connecting rod 10 is rotatably mounted at an eccentric position on the rotating disk 9, the rotation of the rotating disk 9 will push the two sets of movable plates 12 outward through the connecting rod 10.

[0036] The support frame 2 has an internal telescopic groove 14, and a wedge 15 is movably installed inside the telescopic groove 14. One end of the wedge 15 is elastically connected to the telescopic groove 14 by a first spring 16, and the other end of the wedge 15 abuts against the fixing groove 7.

[0037] The design of the wedge 15 and the first spring 16 allows the operator to complete the installation of the mounting bracket 3 simply by pushing the locking block 6 into the positioning groove 5.

[0038] The telescopic groove 14 is formed inside the positioning groove 5, and the number of telescopic grooves 14 and positioning grooves 5 are equal.

[0039] Among them, a limiting sleeve 23 is fixedly installed on one side of the cable board 27, and a button 24 is movably installed inside the limiting sleeve 23. A pin 26 is fixedly installed on one end of the button 24, and the button 24 and the outer wall of the cable board 27 are elastically connected by a third spring 25.

[0040] The operator can press button 24 to move the pressure block 21 upward into the interior of the connecting block 19, and then release button 24 to make the pressure block 21 snap into the interior of the slot 18 by the elasticity of the second spring 20.

[0041] The pressure block 21 has a sloped surface 22 on its front side, and the sloped surface 22 and the ejector pin 26 are positioned correspondingly. The ejector pin 26 penetrates into the interior of the connecting block 19.

[0042] Working principle and usage process of this utility model:

[0043] When the device is put into use, the operator can install the mounting bracket 3 as needed. First, the operator aligns the locking blocks 6 and positioning grooves 5 at both ends of the mounting bracket 3. Then, the locking blocks 6 are inserted into the positioning grooves 5. At this time, the wedge 15 is compressed and retracted into the telescopic groove 14. After the mounting bracket 3 is installed, the telescopic groove 14 and the fixing groove 7 are aligned, allowing the wedge 15 to reset through the elastic potential energy of the first spring 16. The wedge 15 then enters the fixing groove 7, completing the fixing of the mounting bracket 3. When it is necessary to remove the mounting bracket 3, the operator... The operator rotates knob 13 counterclockwise. The rotation of knob 13 drives the rotating disk 9 to rotate. The rotation of the rotating disk 9 will push the two sets of movable plates 12 outward through the connecting rod 10. Further, the distance between the two sets of movable plates 12 increases, causing the two sets of transmission rods 11 to move outward. As the transmission rods 11 are displaced, they will squeeze the wedge 15, causing the wedge 15 to be stored inside the telescopic groove 14. At this time, the operator can pull out the mounting bracket 3 to disassemble it. After installation, the operator can install the electrical equipment on the mounting bracket 3 through the mounting groove 4, which makes it easy to plug in the wires.

[0044] Before wiring, the operator can install the ribbon cable 27 according to the location of the electrical equipment. The operator aligns the connecting blocks 19 on the left and right sides of the ribbon cable 27 with the sockets 17. Then, while pressing the button 24, the operator inserts the connecting block 19 into the socket 17. As the button 24 is pressed, the pin 26 penetrates into the interior of the connecting block 19 and presses the slope surface 22 of the pressure block 21, causing the pressure block 21 to move upward into the interior of the connecting block 19. The connecting block 19 can then be inserted into the socket 17. After insertion, the operator releases the button 24. At this time, the button 24 is reset by the elastic potential energy of the third spring 25, and the pressure block 21 will be inserted downward into the slot 18 by the elasticity of the second spring 20, completing the installation.
