DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 4 As shown, an electrical equipment line protection mechanism described in an embodiment of the present invention comprises a first protective shell 1, one end of the first protective shell 1 is hinged with a second protective shell 2, a first fixing groove 11 is provided at one end of the bottom end of the first protective shell 1 close to the second protective shell 2, a clamping plate 21 is fixed at one end of the bottom end of the second protective shell 2 close to the first fixing groove 11, and a clamping structure is formed between the clamping plate 21 and the first fixing groove 11, a clamping assembly for centering the cable is arranged inside the first protective shell 1, and both sides of the first protective shell 1 and the second protective shell 2 are provided with a splicing assembly for docking; the clamping assembly comprises a clamping plate 3 arranged inside the first protective shell 1 and the second protective shell 2, a rubber pad 31 is fixed to one end of the clamping plate 3 inside the first protective shell 1 close to the second protective shell 2, and a rubber pad 31 is also fixed to one end of the clamping plate 3 inside the second protective shell 2 close to the first protective shell 1;

[0032] When installing the lines inside the electrical equipment, it is necessary to fix them to prevent the cables from being in a messy state and making it inconvenient to maintain the lines. During installation, the adjacent cables are brought closer to the middle. At this time, the first protective shell 1 and the second protective shell 2 are in an open state. Then, the first protective shell 1 and the second protective shell 2 are placed on both sides of the cable. Then, the first protective shell 1 and the second protective shell 2 are pushed toward the middle to clamp the cable in the middle. During clamping, the cable contacts the rubber pad 31, and the cable pushes the rubber pad 31 to drive the clamping plate 3 to automatically move and adjust the position. The clamping plate 3 moves and adjusts inside the first protective shell 1 and the second protective shell 2 to enable the first protective shell 1 and the second protective shell 2 to clamp lines with different outer diameters. When the first protective shell 1 and the second protective shell 2 are closed, the clamping plate 21 is inserted into the inside of the first fixing groove 11, and the first protective shell 1 and the second protective shell 2 can be fixed between them. At this time, the outside of the line can be fixed and the outside of the line can be protected. When the line is long, multiple protective mechanisms need to be protected at the same time. At this time, multiple protective mechanisms can be spliced ​​through splicing components. Different numbers of protective structures are installed according to usage requirements to achieve protection of the line.

[0033] like Figures 1 to 5 As shown, the clamping assembly also includes a guide rod 32 fixed to one end of the clamping plate 3 away from the rubber pad 31, a conical spring 33 is sleeved on the outside of the guide rod 32, one end of the conical spring 33 is fixedly connected to the clamping plate 3, the other end of the conical spring 33 inside the first protective shell 1 is fixedly connected to the inner wall of the first protective shell 1, the other end of the conical spring 33 inside the second protective shell 2 is fixedly connected to the inner wall of the second protective shell 2, two sets of guide holes 34 are opened inside the first protective shell 1 and the second protective shell 2, and the guide rod 32 runs through the inside of the guide hole 34;

[0034] When the clamp 3 clamps the cable, the cable will push the clamp 3, and the clamp 3 squeezes the conical spring 33. At this time, the clamp 3 can be automatically adjusted to a position matching the outer diameter of the cable. During adjustment, the conical springs 33 on both sides support the clamp 3, so that the clamp 3 can push the cable to a position in the middle of the first protective shell 1 and the second protective shell 2. In the process of the clamp 3 squeezing the conical spring 33, the guide rod 32 retracts and contracts inside the guide hole 34, which can guide the clamp 3 and prevent the clamp 3 from offset during movement.

[0035] like Figures 1 to 6 As shown, a suction cup 4 is disposed below the first protective shell 1 and the second protective shell 2, and a support column 42 is fixed to the top of the suction cup 4. The support column 42 is respectively fixed to one end of the first protective shell 1 away from the second protective shell 2 and one end of the second protective shell 2 away from the first protective shell 1;

[0036] After the cable is fixed inside the first protective shell 1 and the second protective shell 2, in order to make the cable more stable, the first protective shell 1 and the second protective shell 2 need to be fixed. At this time, the suction cup 4 under the first protective shell 1 and the second protective shell 2 is pressed against the inner wall of the electrical equipment. At this time, the suction cup 4 can be adsorbed on the inner wall of the electrical equipment, so that the first protective shell 1 and the second protective shell 2 can be fixed, and it is more stable when used.

[0037] like Figures 1 to 8 As shown, a plurality of tooth grooves 321 are provided at equal intervals below the guide rod 32, a first gear 35 is provided below the end of the guide hole 34 away from the clamping plate 3, both sides of the first gear 35 are rotatably connected with support plates 351, one end of the support plate 351 is respectively fixedly connected to the first protective shell 1 and the second protective shell 2, a side of the first gear 35 close to the support column 42 is connected to the second gear 352 through a rotating shaft, and a side of the second gear 352 away from the first gear 35 is also rotatably connected to the support plate 351, and the first gear 35 is connected to the second gear 352 through a rotating shaft. A lifting plate 43 is provided below the second gear 352 near the first protective shell 1, a tooth plate 431 is fixed to the top of the lifting plate 43, the tooth plate 431 is provided between the second gear 352 and the first protective shell 1, a lifting column 432 is fixed to the bottom end of the lifting plate 43, the lifting column 432 is inserted into the inside of the support column 42, a piston 433 is fixed to the bottom end of the lifting column 432, the outer diameter of the piston 433 matches the inner diameter of the cavity of the support column 42, and an air inlet and outlet hole 421 is provided at the bottom end of the support column 42;

[0038] When the cable pushes the clamping plate 3, the cables with different outer diameters push the clamping plate 3 to move different distances. When the guide rod 32 is extended and retracted inside the guide hole 34, it drives the first gear 35 to rotate through the tooth groove 321. The first gear 35 also drives the second gear 352 to rotate. When the second gear 352 rotates, it drives the tooth plate 431 to move upward. At this time, the tooth plate 431 drives the lifting plate 43 to move upward, and the lifting plate 43 pulls the lifting column 432 to drive the piston 433 to move upward inside the support column 42. At this time, the support column 42 draws air into the suction cup 4 through the inlet and outlet holes 421, so that the suction cup 4 can be automatically adsorbed on the inner wall of the electrical equipment. The diameter of the opening at the top of the support column 42 is larger than the outer diameter of the lifting column 432, so there will be a gap for air in and out.

[0039] like Figures 1 to 8 As shown, a rotating hole 422 is opened in the middle of the bottom end of the support column 42, and the air inlet and outlet holes 421 are arranged on both sides of the rotating hole 422. A rotating block 44 is arranged below the support column 42, and a rotating column 442 is fixed on the top of the rotating block 44. The rotating column 442 is inserted into the rotating hole 422. The outer diameter of the rotating column 442 matches the inner diameter of the rotating hole 422, and docking holes 441 are opened on both sides of the rotating block 44.

[0040] During the clamping process of the first protective shell 1 and the second protective shell 2, the clamping plate 3 will move, but at this time it is not convenient to adsorb the suction cup 4 on the inner wall of the electrical equipment, so a rotating block 44 is provided, and the rotating block 44 can block the air inlet and outlet holes 421. When the air inlet and outlet holes 421 inhale, the rotating block 44 will be adsorbed, and at this time, the area below the piston 433 inside the second protective shell 2 can be in a vacuum state.

[0041] like Figures 1 to 8 As shown, a lifting frame 443 is provided below the rotating block 44, a telescopic cylinder 444 is fixed to the top of the lifting frame 443, guide sliders 447 are fixed to both sides of the top of the telescopic cylinder 444, a telescopic groove is provided in the middle of the bottom end of the rotating block 44, guide slide grooves 446 are provided on both sides of the inside of the telescopic groove, and the guide slider 447 is slidably connected inside the guide slide groove 446, telescopic columns are fixed to both ends of the lifting frame 443, guide cylinders 445 are provided to both ends above the lifting frame 443, the top of the guide cylinder 445 is fixedly connected to the bottom end of the support column 42, and the telescopic column of the lifting frame 443 is slidably connected inside the guide cylinder 445;

[0042] When the suction cup 4 is fixed on the inner wall of the electrical equipment, the first protective shell 1 and the second protective shell 2 will be pushed. When pushing, the lifting frame 443 will contact the inner wall of the electrical equipment. When the first protective shell 1 and the second protective shell 2 are pushed, the lifting frame 443 will be pushed. At this time, the lifting frame 443 will push the telescopic cylinder 444 to move inside the telescopic groove inside the rotating block 44. At this time, the guide slider 447 slides inside the guide slide groove 446. Under the guidance of the guide slide groove 446, the rotating block 44 can be rotated 90°. At this time, the rotating block 44 can drive the docking hole 441 After rotating 90°, it is connected with the inside of the air inlet and outlet 421. At this time, the air inside the suction cup 4 can be sucked into the inside of the support column 42, and the suction cup 4 can be automatically adsorbed to the inner wall of the electrical equipment. The larger the outer diameter of the cable, the greater the distance the clamping plate 3 is pushed to move. The greater the movement distance of the clamping plate 3, the greater the upward movement distance of the piston 433, which can allow the support column 42 to draw more air into the suction cup 4, making the suction force of the suction cup 4 greater. At the same time, the larger the outer diameter of the cable, the greater its weight. Therefore, the suction cup 4 can automatically adjust the suction force according to the weight of the cable, and can fix the cable more firmly.

[0043] like Figures 1 to 8 As shown, a return spring 448 is fixed inside the telescopic cylinder 444, and the top of the return spring 448 is closely attached to the top of the telescopic slot inside the rotating block 44;

[0044] When the first protective shell 1 and the second protective shell 2 are subsequently disassembled, the suction cup 4 needs to be separated from the inner wall of the electrical equipment. After the suction cup 4 is separated, the reset spring 448 will push the lifting frame 443 and the rotating block 44 to reset. When the cable is taken out from the first protective shell 1 and the second protective shell 2, the elastic force of the conical spring 33 will cause the clamping plate 3 to drive the guide rod 32 to reset. At this time, the piston 433 will descend inside the support column 42. At this time, the piston 433 will discharge air into the inlet and outlet holes 421. The push of the air will cause the rotating block 44 to move downward. At this time, a gap will be generated between the rotating block 44 and the inlet and outlet holes 421, allowing the air to be discharged into the interior of the suction cup 4, making it convenient to reset the piston 433.

[0045] like Figures 1 to 7 As shown, a lifting strip 41 is fixed to one side of the suction cup 4;

[0046] When the suction cup 4 needs to be separated from the inner wall of the electrical device, the lifting strip 41 is pulled upwards. At this time, one side of the suction cup 4 is lifted up, and air enters the interior of the suction cup 4, causing the suction cup 4 to lose its suction force. At this time, the suction cup 4 can be separated from the inner wall of the electrical device.

[0047] like Figures 1 to 5 As shown, the splicing assembly includes a slot block 55 fixed on one side of the first protective shell 1 and the second protective shell 2, respectively. The other sides of the first protective shell 1 and the second protective shell 2 are respectively provided with a card column 5, and the top and bottom ends of the card column 5 are fixed with a support block 51, and a card column 5 and the slot block 55 form a snap-fit ​​structure;

[0048] When multiple protective mechanisms are needed, after the first protective shell 1 and the second protective shell 2 are installed, the clamping column 5 at one end thereof is aligned with the clamping slot block 55 of the other protective mechanism, and then the clamping column 5 is inserted into the interior of the clamping slot block 55. At this time, the protective mechanisms can be fixed. When used in a position where the cable needs to be bent, one group of the clamping column 5 and the clamping slot block 55 is separated according to the bending position. At this time, the protective mechanisms can be flipped through the clamping column 5 and the clamping slot block 55, so that multiple protective mechanisms can be easily connected.

[0049] like Figures 1 to 5 As shown, a telescopic hole 53 is provided on one side of the first protective shell 1 and the second protective shell 2 near the support block 51, a threaded hole 531 is provided on one end of the telescopic hole 53 away from the clamping plate 3, a telescopic rod 52 is fixed on one side of the support block 51 near the telescopic hole 53, the telescopic rod 52 is inserted into the telescopic hole 53, a second fixing groove 521 is provided on one side of the telescopic rod 52 near the threaded hole 531, and a bolt 54 is threadedly connected to the inner part of the threaded hole 531;

[0050] When the card column 5 and the card slot block 55 are connected, a certain distance will remain between the card column 5 and the card slot block 55 in some areas. At this time, in order to facilitate the connection, the bolt 54 is loosened from the inside of the threaded hole 531. At this time, the telescopic rod 52 can be slid and adjusted inside the telescopic hole 53. After adjusting to a suitable distance, the bolt 54 is tightened into the threaded hole 531. At this time, the bolt 54 presses against the inner wall of the second fixing groove 521 to fix the telescopic rod 52, so that the card column 5 and the card slot block 55 can be easily connected.
