[0022] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Embodiment 1: Refer to Figures 1 - 5 , the present invention provides a technical solution: a cable junction box, including a first protective shell 1, four groups of clamping rods 4 are arranged on the inner wall of the first protective shell 1, and one side of the four groups of clamping rods 4 close to the first protective shell 1 is fixedly connected to the bottom of the inner wall of the first protective shell 1. The middle end of the top of the first protective shell 1 is fixedly connected with a connecting plate 3. A second protective shell 2 is arranged on the top of the first protective shell 1. It also includes: A pressing mechanism 5, the pressing mechanism 5 includes a protective shell 501, one side of the protective shell 501 close to the first protective shell 1 is fixedly connected to the outer wall of the first protective shell 1. A first spring 503 is arranged on the inner wall of the protective shell 501. One side of the first spring 503 close to the protective shell 501 is fixedly connected to the bottom of the inner wall of the protective shell 501. The side of the first spring 503 away from the protective shell 501 is fixedly connected with a lower pressing plate 502. By setting the first spring 503, it can ensure that when the second protective shell 2 does not need to be fixed, the first spring 503 can promptly push the lower pressing plate 502 back to its original position, effectively avoiding interference with the lower pressing plate 502 during subsequent use and ensuring the smoothness of its next use. On the left and right sides of the inner wall of the protective shell 501, inclined rods 504 are fixedly connected. One side of the two groups of inclined rods 504 away from the protective shell 501 is rotatably connected to a rotating rod 505 through a first rotating shaft. One side of the two groups of rotating rods 505 close to the protective shell 501 is rotatably connected to a swinging rod 506 through a second rotating shaft. One side of the two groups of swinging rods 506 away from the lower pressing plate 502 is fixedly connected with a positioning block 507. Moving blocks 508 are arranged on the inner walls of the two groups of positioning blocks 507. By setting the moving blocks 508, the position of the rotating plate 510 can be accurately adjusted to ensure that the rotating plate 510 is firmly embedded in the inner wall of the pushing block 601, thereby ensuring the tight fixation of the first protective shell 1 and the second protective shell 2. One side of the outer walls of the two groups of moving blocks 508 close to the outer wall of the positioning block 507 is slidably connected to the outer wall of the positioning block 507. The swinging rod 506 is used to drive the positioning block 507 to rotate at an angle. One side of the two groups of moving blocks 508 close to the lower pressing plate 502 is rotatably connected to two groups of rotating plates 510 through a third rotating shaft. On the side where the four groups of rotating plates 510 are close to each other, a second spring 509 is fixedly connected. Two groups of pressing mechanisms 5 are arranged symmetrically with the middle of the first protective shell 1 as the center. The rotating plate 510 is used to fix the position of the positioning block 507 after it moves.

[0025] The working principle of this embodiment is as follows: When the staff installs the first protective case 1 and the second protective case 2, they need to first pick up the second protective case 2, move it to the top of the first protective case 1, and then move the second protective case 2 downward. During the downward movement, the second protective case 2 will drive the push block 601 to move downward synchronously. When the push block 601 moves downward, it will first contact the top of the lower pressure plate 502. As the push block 601 continues to move, the lower pressure plate 502 is pushed downward, thereby pushing the first spring 503 to contract downward. When the first spring 503 contracts, it will pull the rotating rod 505 to rotate toward the side close to the lower pressure plate 502. While the rotating rod 505 rotates, it will drive the swinging rod 506 to rotate at the same angle. When the rotating rod 505 rotates to a certain angle, it will swing the swinging rod 506 upward. When the swinging rod 506 rotates upward, it drives the positioning block 507 to move upward, causing the moving block 508 to slide on the positioning block 507 and move to the inner wall of the push block 601. At this time, the rotating plate 510 is no longer restricted, and the second spring 509 starts to rebound, pushing the rotating plate 510 toward the inner wall of the push block 601 to complete their combination.

[0026] Embodiment 2: Please refer to Figure 6, on the basis of the first embodiment, the present invention provides a technical solution: further comprising a fixing mechanism 6, the fixing mechanism 6 includes a pushing block 601, one side of the pushing block 601 close to the second protective shell 2 is fixedly connected to the outer wall of the second protective shell 2, a first sliding rod 602 is arranged inside the pushing block 601, both the upper and lower ends of the first sliding rod 602 are fixedly connected to the inner wall of the pushing block 601, a third spring 604 is fixedly connected to the top of the inner wall of the pushing block 601, one side of the third spring 604 away from the inner wall of the pushing block 601 is in contact with the outer wall of the first sliding rod 602, a rectangular plate 603 is slidably connected to the outer wall of the first sliding rod 602, and the third spring 604 is used to pull the rectangular plate 603 to reset, one side of the rectangular plate 603 close to the third spring 604 is fixedly connected to the bottom of the third spring 604, a bent plate 605 is fixedly connected to the side of the rectangular plate 603 away from the third spring 604, the bent plate 605 penetrates the pushing block 601, and the bent plate 605 is used to control the moving distance of the rectangular plate 603, two groups of limiting blocks 606 are fixedly connected to the outer wall of the pushing block 601 away from the second protective shell 2, a top rod 607 is arranged inside each of the two groups of limiting blocks 606. After the top rod 607 is provided, when the bent plate 605 finishes moving, the top rod 607 can effectively fix it, preventing the bent plate 605 from being displaced due to the pulling force of the third spring 604, thereby ensuring that the stability of the entire structure is not damaged. One side of each of the two groups of top rods 607 close to the inner wall of the limiting block 606 is slidably connected to the inner wall of the limiting rod, and a pulling rope 608 is fixedly connected to the side of each of the two groups of top rods 607 close to each other. By setting the pulling rope 608, the top rod 607 can be pulled in time to limit the bent plate 605, thereby ensuring the normal operation of the fixing mechanism 6. Two groups of the fixing mechanism 6 are symmetrically arranged with the middle of the first protective shell 1 as the center, and the top rod 607 is used to fix the bent plate 605.

[0027] The working principle of this embodiment is as follows: when the second protective shell 2 continues to move downward, it will drive the pushing block 601 to move synchronously. After the bottom of the second protective shell 2 is in contact with the top of the connecting plate 3, the pushing block 601 will still continue to move a certain distance. After the pushing block 601 finishes moving, the staff begins to pull the bent plate 605 downward. During the downward movement of the bent plate 605, it will drive the rectangular plate 603 to move synchronously, and the rectangular plate 603 will slide downward along the outer wall of the first sliding rod 602. As the rectangular plate 603 moves downward, the third spring 604 is gradually stretched. When the bent plate 605 continues to move, it will contact the bottom pulling rope 608 and push the pulling rope 608 to move. When the pulling rope 608 moves downward, it will drive the top rod 607 to move in the limiting block 606 in the direction of approaching each other. At this time, the bent plate 605 is exactly on the horizontal movement path of the top rod 607, and the top rod 607 will be inserted into the bent plate 605, thus realizing the fixation.

[0028] Embodiment Three: Please refer to Figures 7 - 8, based on the first and second embodiments, the present invention provides a technical solution: It further includes a docking mechanism 7. The docking mechanism 7 includes a pulling rod 701. One side of the pulling rod 701 close to the second protective shell 2 is fixedly connected to the top inner wall of the second protective shell 2. There are two groups of fourth springs 706 arranged inside the pulling rod 701, and the pulling rod 701 is used to limit the positions of the fourth springs 706. One side of each of the two groups of fourth springs 706 away from the pulling rod 701 is fixedly connected to a fitting block 707. One side of the fitting block 707 away from the pulling rod 701 is fixedly connected to a second fixing rod 705. The fourth spring 706 is used to push the fitting block 707 to tilt at an angle. One side of the second fixing rod 705 close to the first protective shell 1 is slidably connected to a second sliding rod 704. By setting the second sliding rod 704, the connection relationship between the first fixing rod 703 and the second fixing rod 705 can be changed according to different usage scenarios, thereby effectively expanding the application range of the docking mechanism 7. One side of the second sliding rod 704 away from the second fixing rod 705 is provided with a first fixing rod 703. One side of the first fixing rod 703 close to the second sliding rod 704 is slidably connected to the outer wall of the second sliding rod 704. The first fixing rod 703 is used to drive the second fixing rod 705 to move. One side of the first fixing rod 703 close to the first protective shell 1 is an arc-shaped plate 702. One side of the arc-shaped plate 702 close to the pulling rod 701 is in contact with the inner wall of the pulling rod 701. The docking mechanism 7 is provided in four groups and is installed at the four corners of the inner wall of the second protective shell 2. The arc-shaped plate 702 is used to combine the pulling rod 701 with the clamping rod 4.

[0029] The working principle of this embodiment is as follows: When the staff drives the second protective shell 2 to move, the second protective shell 2 will synchronously drive the pulling rod 701 to displace. As the pulling rod 701 moves downward, the second fixing rod 705 also moves downward accordingly. During the movement of the second fixing rod 705, the fitting block 707 is driven, and at the same time, the fourth spring 706 also moves. Due to the elastic force of the fourth spring 706, it will push the fitting block 707, causing the fitting block 707 to push the second fixing rod 705 to tilt at an angle. At this time, the staff starts to move the second sliding rod 704 towards the side of the second fixing rod 705. After the second sliding rod 704 moves into place, it will be in close contact with the second fixing rod 705. As the second fixing rod 705 tilts at an angle, the second sliding rod 704 will also tilt accordingly. During the tilting process of the second sliding rod 704, the first fixing rod 703 is also driven to tilt at an angle. After the first fixing rod 703 tilts, it will drive the fitting block 707 to change its angle, and finally the fitting block 707 is exposed from the notch of the clamping rod 4, thus completing the clamping and fixing action.
