The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a busbar trunking cover plate insertion device, specifically including a cover plate mechanism 100, which includes a fixing component 101 and a closing component 102, the closing component 102 being located on one side of the fixing component 101; and an insertion mechanism 200, which includes an insertion shell 201 and an insertion post 202, the insertion post 202 being located on the insertion shell 201.

[0038] In this embodiment, if the operator needs to fix the insertion mechanism 200 on the cover plate mechanism 100, the insertion post 202 needs to be aligned with the fixing seat 101b and inserted. At this time, the sealing ring 102a will rotate around the axis of the fixing seat 101b, driving the two sealing plates 102b to open and compress the spring 102c. When the two sealing plates 102b are fully opened, the insertion post 202 will be fixed by the cooperation of the fixing seat 101b and the sealing ring 102a, keeping the sealing plates 102b open.

[0039] Example 2

[0040] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, the upper cover plate 101a includes a sealing plate groove 101a-1, a sealing column groove 101a-2, and a connecting hole 101a-3. The sealing column groove 101a-2 is located on one side of the sealing plate groove 101a-1, and the connecting hole 101a-3 is located on one side of the sealing column groove 101a-2.

[0042] It should be noted that the sealing plate groove 101a-1 is a cuboid groove, and there are two sealing plate grooves 101a-1. The size of the sealing plate groove 101a-1 is adapted to the sealing plate 102b; the sealing column groove 101a-2 is an annular groove, and there are two sealing column grooves 101a-2. The two sealing column grooves 101a-2 rotate 180 degrees around the axis of the fixing seat 101b; the connecting hole 101a-3 is a circular hole, and the diameter of the connecting hole 101a-3 is the same as the inner diameter of the fixing seat 101b.

[0043] Furthermore, the fixing seat 101b includes a spiral groove 101b-1, a first vertical groove 101b-2 and a rotating groove 101b-3. The first vertical groove 101b-2 is located on one side of the spiral groove 101b-1, and the rotating groove 101b-3 is located below the spiral groove 101b-1.

[0044] It should be noted that the height of the spiral groove 101b-1 is greater than that of the first vertical groove 101b-2, and the length of the spiral groove 101b-1 is also greater than that of the first vertical groove 101b-2; there are two spiral grooves 101b-1, which rotate 180 degrees around the fixed base 101b, and the spiral groove 101b-1 itself rotates by less than 70 degrees; there are two first vertical grooves 101b-2, which rotate 180 degrees around the fixed base 101b; the rotating groove 101b-3 is an annular groove, which rotates 180 degrees around the fixed base 101b, and the rotating angle of a single rotating groove 101b-3 is 60 degrees.

[0045] Preferably, the sealing ring 102a includes a sealing ring 102a-1, a pressure plate 102a-2, and a spring 102a-3, with the pressure plate 102a-2 located in the sealing ring 102a-1 and the spring 102a-3 located below the pressure plate 102a-2; the sealing plate 102b includes a retaining groove 102b-1, which is located on the sealing plate 102b.

[0046] It should be noted that the sealing ring 102a-1 is slidably connected to the rotating groove 101b-3, and the pressure plate 102a-2 is slidably connected to the sealing ring 102a-1; one end of the spring 102a-3 is fixed to the bottom of the pressure plate 102a-2, and the other end is fixed to the upper surface of the upper cover plate 101a; the sealing ring 102a-1 is annular, and the pressure plate 102a-2 is adapted to the sealing ring 102a-1; the retaining groove 102b-1 is a straight groove, and the end of the retaining groove 102b-1 near the edge of the sealing plate 102b is connected to the sealing groove 101a-2 on a line perpendicular to the axis of the sealing plate 102b.

[0047] In this embodiment, when the operator inserts the plug 202 into the spiral groove 101b-1, the plug 202 will slide along the spiral groove 101b-1 to the bottom of the spiral groove 101b-1. At this time, the plug 202 drives the sealing ring 102a to rotate together. The rotating sealing ring 102a-1 will open the two sealing plates 102b through the locking groove 102b-1. When the plug 202 rotates to the bottom of the spiral groove 101b-1, the plug 202 will rise under the elastic force of the spring 102a-3, driving the pressure plate 102a-2 to squeeze the plug 202, causing the plug 202 to move upward until it slides into the first vertical groove 101b-2, completing the fixation.

[0048] Example 3

[0049] Reference Figures 1-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, the sealing ring 102a-1 includes a rotating block 102a-1a, a retaining post 102a-1b, a second vertical groove 102a-1c, a plate hole 102a-1d, and a plate groove 102a-1e. The retaining post 102a-1b is located below the rotating block 102a-1a, the second vertical groove 102a-1c is located outside the rotating block 102a-1a, the plate hole 102a-1d is located on one side of the second vertical groove 102a-1c, and the plate groove 102a-1e is located below the plate hole 102a-1d.

[0051] It should be noted that there are two rotating blocks 102a-1a, both of which are square cylinders, spaced 180 degrees apart. The rotating blocks 102a-1a are slidably connected to the rotating groove 101b-3. The retaining posts 102a-1b are circular cylinders, spaced 180 degrees apart, and slidably connected to the retaining post groove 102b-1 and the sealing post groove 101a-2. The second vertical groove 102a-1c... There are two, with a 180-degree interval between the two second vertical grooves 102a-1c. The length of the second vertical groove 102a-1c is longer than that of the first vertical groove 101b-2, and the top of the second vertical groove 102a-1c is not closed. The tablet hole 102a-1d is connected to the tablet groove 102a-1e. The size of the tablet hole 102a-1d and the tablet groove 102a-1e is adapted to the tablet pressing 102a-2. The tablet hole 102a-1d is slidably connected to the tablet groove 102a-1e and the tablet pressing 102a-2.

[0052] Furthermore, the tablet 102a-2 includes an insert 102a-2a and a baffle 102a-2b, with the baffle 102a-2b located below the insert 102a-2a.

[0053] It should be noted that the shape and size of the insert 102a-2a are adapted to the plate hole 102a-1d, and the insert 102a-2a is slidably connected to the plate hole 102a-1d. The insert 102a-2a is an arc-shaped plate. The shape and size of the baffle 102a-2b are adapted to the plate groove 102a-1e, and the baffle 102a-2b is slidably connected to the plate groove 102a-1e.

[0054] In this embodiment, when the operator wants to inspect the busbar, the plug 202 needs to be aligned with the spiral groove 101b-1, inserted downwards, and rotated clockwise. Since the fixing seat 101b is fixed on the upper cover plate 101a, the plug 202 will drive the sealing ring 102a to rotate clockwise. The rotating sealing ring 102a will cause the locking pins 102a-1b to rotate clockwise together, thereby causing the locking pins 102a-1b to slide in the locking pin groove 102b-1, driving the two sealing plates 102b to open, and the spring piece 102c to be compressed. As the plug pin 202 rotates to the bottom of the spiral groove 101b-1, the bottom of the plug shell 201 will press against the baffle 102a-2b and compress the spring 102a-3. After the plug pin 202 rotates to the bottom of the spiral groove 101b-1, the top of the plug pin 202 is no longer limited by the spiral groove 101b-1, and the plug shell 201 will rise under the elastic force of the spring 102a-3, thereby causing the plug pin 202 to slide into the top of the first vertical groove 101b-2 and complete the fixation. After that, the operator can release the plug mechanism 200 and insert the detection probe through the limiting hole 201a for detection.

[0055] It should be noted that after the operator has inspected the busbar, the operator only needs to press down on the plug-in mechanism 200 until the plug-in post 202 slides to the bottom of the first vertical groove 101b-2. At this time, the side of the plug-in post 202 is no longer limited by the first vertical groove 101b-2. Since the compressed spring 102c always applies elastic force to the sealing plate 102b, the sealing plate 102b has a tendency to close. The sealing plate 102b will also give the sealing ring 102a a tendency to rotate counterclockwise through the locking post 102a-1b. The plug-in post 202, which has lost the side limit of the first vertical groove 101b-2, will rotate counterclockwise along the spiral groove 101b-1 under the elastic force of the spring 102c until it reaches the spiral groove 101b-1. After that, the operator can directly remove the plug-in mechanism 200.
