It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0024] The specific implementation of the utility model will be described in detail below in combination with specific examples.

[0025] Please refer to Figures 1 to 4 The utility model embodiment provides a cable joint explosion-proof box, and the cable joint explosion-proof box comprises a bottom box 1 and a top box 2.

[0026] In the embodiment of the utility model, please refer to Figures 1 to 4 Both sides inside the bottom box 1 are provided with positioning assemblies 3; the positioning assembly 3 comprises a mounting plate 31, the mounting plate 31 is fixedly installed on one side inside the bottom box 1, a positioning frame 311 fixedly connected with the mounting plate 31 is installed on the top of the mounting plate 31, convex rods 32 fixedly connected with the positioning frame 311 are installed on both sides of the top of the mounting plate 31, and the outer walls of the two convex rods 32 are provided with the same positioning plate 33 which is slidingly connected; a handle 331 fixedly connected with the positioning plate 33 is arranged on the top of the positioning plate 33, and a limiting sleeve a 34 threadedly connected with the convex rod 32 is arranged on the outer wall of the convex rod 32.

[0027] It should be noted that: through the setting of the positioning assembly 3, during installation, the joint of the cable can be placed in the center of the bottom box 1, and the cable can be placed on the positioning frame 311, then the positioning plate 33 is sleeved on the convex rod 32 and the limiting sleeve a 34 is screwed to fix the positioning plate 33, so that the preliminary positioning and fixing of the cable can be realized, then the staff can directly hold the cable, and the sealing rubber strip or the armored belt can be wound on the outer part of the cable opposite to the end part of the bottom box 1, the installation operation part can be reduced without measuring and marking, and the installation portability of the device can be improved.

[0028] In the embodiment of the utility model, please refer to Figures 1 to 4The center of the bottom box 1 is provided with a fixedly connected support plate 4, both sides of the top of the support plate 4 are provided with fixedly connected columns 41, the outside of the column 41 is provided with a slidingly connected butt plate 42, and the outside of the column 41 is provided with a threadedly connected limiting sleeve b43, the inside of the top box 2 is provided with a penetrating hole 22 at a position opposite to the column 41, the inner wall of the penetrating hole 22 is abutted against and slidingly connected with the outer wall of the column 41, and the inside of the top box 2 is fixedly provided with a communicating filling pipe 23, and the outside of the filling pipe 23 is provided with a threadedly connected sealing cover 24.

[0029] It should be noted that, through the penetrating hole 22, the penetrating hole 22 can be smoothly sleeved outside the column 41 when the top box 2 is butt-jointed, so that the top box 2 can be smoothly moved downward and butt-jointed with the bottom box 1 below, and compared with the traditional butt-joint and insertion bolt fixing, the butt-joint assembly of the two is more flexible.

[0030] Through the arrangement of the filling pipe 23, after the assembly of the bottom box 1 and the top box 2 is completed, the filling pipe 23 can facilitate the staff to fill the sealing glue into the assembled explosion-proof box to fill and seal the inside of the explosion-proof box.

[0031] In the embodiment of the utility model, please refer to Figures 1 to 4 The side wall of the bottom box 1 is provided with a butt-joint groove 11, the side wall of the top box 2 is provided with a fixedly connected butt-joint sealing strip 21, the inner wall of the butt-joint groove 11 is abutted against the outer wall of the butt-joint sealing strip 21, and the end of the explosion-proof box formed after the butt-joint of the bottom box 1 and the top box 2 is provided with a threadedly connected limiting cylinder 5.

[0032] It should be noted that, through the arrangement of the butt-joint groove 11 and the butt-joint sealing strip 21, after the butt-joint of the bottom box 1 and the top box 2 is completed, the abutment of the butt-joint groove 11 and the butt-joint sealing strip 21 can improve the sealing effect of the butt-joint part, and at the same time, through the sleeving of the limiting cylinder 5 at the end of the two, the limiting cylinder 5 can limit the end of the bottom box 1 and the top box 2 after the butt-joint, so that the stability after the butt-joint of the two can be improved.

[0033] The working principle of the cable joint explosion-proof box is as follows:

[0034] When the device is used, the staff can first sleeve the limiting cylinder 5 outside the two cables to be butt-jointed, and then butt-joint the cables.

[0035] After the cables on both sides are connected, the cables can be taken out and the connected part of the cables can be placed in the center of the bottom box 1. Then, the cables on both sides can be placed in the positioning frames 311 in the positioning components 3 on both sides. After the cables are placed, the positioning plate 33 can be taken out and placed on the outside of the protruding rod 32, so that the positioning plate 33 and the positioning frame 311 abut against the outer wall of the cable. After the positioning plate 33 is placed, the limiting sleeve a34 can be taken out and the limiting sleeve a34 can be screwed on the protruding rod 32 until the bottom of the limiting sleeve a34 abuts against the top of the positioning plate 33, thus achieving the initial positioning of the cable.

[0036] After the initial positioning of the cable is completed, the staff can pick up the cable as needed and wrap the sealing tape or armor tape around the corresponding part of the cable outer wall and the end of the bottom box 1. This can protect the joint between the cable outer wall and the bottom box 1. This wrapping method eliminates the need for the staff to use a measuring ruler to measure the length of the bottom box 1 and make measurement marks on the cable for positioning the sealing tape or armor tape. This reduces the number of operating parts for the staff and makes the operation more convenient.

[0037] After the sealing tape and armor tape are wrapped, the top box 2 can be taken out and placed on the outside of the top column 41 of the support plate 4. The top box 2 can be moved down along the column 41 so that the top box 2 can be smoothly connected with the bottom box 1. Then, the docking plate 42 and the limiting sleeve can be taken out and placed on the outside of the column 41 in sequence. Then, the limiting sleeve b43 can be turned until the bottom end of the limiting sleeve b43 abuts against the top of the docking plate 42, so that the bottom box 1 and the top box 2 can be quickly connected. Then, the limiting cylinder 5, which is pre-fitted on the outside of the cable, can be moved to the bottom end of the bottom box 1 and the top box 2 after docking, until the inner wall of the limiting cylinder 5 is connected to the outer thread structure of the bottom box 1 and the top box 2. This completes the secondary limiting of the docking of the bottom box 1 and the top box 2, thereby improving the stability of the docking.

[0038] Next, the staff can add the required sealant through the injection tube 23 into the assembled explosion-proof box to fill and seal the inside of the explosion-proof box. Then, tighten the sealing cap 24 to complete the installation of the device.

[0039] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
