A spring 11 is fixedly connected between the upper surface of the limit block 12 and the lower surface of the inner threaded cylinder 3 (the inner threaded cylinder 3 can be rotated to disassemble it, thereby allowing the spring 10 and spring 11 inside the mounting groove to be disassembled and replaced, avoiding the situation where the spring 10 and spring 11 cannot be used normally due to the weakening of their elasticity after long-term use). A sealing rubber gasket 15 (the sealing rubber gasket 15 is nitrile rubber with added flame retardant material) is fixedly connected to the upper surface of the connecting seat 1. An extrusion groove is opened on the lower surface of the connecting seat 2. The sealing rubber gasket 15 is inserted into the extrusion groove and the upper surface of the rubber gasket 15 contacts the inner wall of the extrusion groove. A connecting mechanism 6 is also included. Connecting mechanism 6 includes mounting groove 2 61, lever 62, slide groove 63, slider 2 65, locking block 1 67, and locking block 2 69. Locking blocks 2 69 are all fixedly connected to the lower side of connecting seat 2 1. The connecting seat 2 1 has mounting groove 2 61 inside each mounting groove 2 61, and lever 62 is rotatably connected inside each mounting groove 2 61. Slide grooves 63 are provided at both the upper and lower ends of lever 62. Sliding blocks 2 65 are slidably connected inside the lower slide groove 63. The upper end of sliding blocks 2 65 is slidably connected to the upper side of the connecting seat 1. Locking blocks 1 67 are fixedly connected to the lower end of sliding blocks 2 65. Locking blocks 1 67 are slidably connected to the vertically adjacent mounting groove 2 61. Locking blocks 1 67 cooperate with the vertically adjacent locking blocks 2 69.

This moves the first slider 64 downwards. As the first slider 64 moves downwards, it slides inside the slide groove 63. At this time, the upper end of the lever 62 moves downwards, causing the lower end of the lever 62 to move upwards. This moves the second slider 65 upwards, and the third spring 68 contracts, causing the first locking block 67 to move upwards into the second mounting groove 61. At this time, the upper end of the second slider 65 slides to the upper side of the first connecting seat 1 and inserts into the first mounting groove 10. The upper end of the second sliding rod 65 presses upwards against the limiting block 12, and the second spring 11 contracts. At this time, the second connecting seat 2 is rotated. The rotation of the second connecting seat 2 causes the second locking block 69 to move, and at the same time, it moves the second mounting groove 61. Move 10, causing the right-side locking block 69 to move to the front of the right-side locking block 67, and the left-side locking block 68 to move to the rear of the left-side locking block 67. At this time, the mounting slot 10 moves to the upper side of the slide rod 66, the spring 3 68 relaxes, pushing the slider 2 65 downward. The upper end of the slider 2 65 moves into the interior of the connecting seat 2. The spring 2 11 relaxes, the limiting block 12 moves downward, causing the lower end of the lever 62 to move downward, and the upper end of the lever 62 to move upward, driving the slider 1 64 upward. This causes the slide rod 66 to move upward and slide to the upper side of the connecting seat 1. At this time, the upper side of the slide rod 66 is located inside the mounting slot 10, and the slide rod 66 is located directly below the top block 8, thus connecting the connecting seat 1 and the connecting seat 2.When it is necessary to unlock the connection between connector 1 and connector 2, move the lever 7 downwards to move the top block 8 downwards. This relaxes the spring 9, causing the top block 8 to press against the slide rod 66. The slide rod 66 then moves downwards into the mounting groove 61, causing the upper end of the lever 62 to move downwards and the lower end to move upwards. This causes the slider 65 to move upwards, moving the locking block 67 upwards into the mounting groove 61. At this point, locking blocks 67 and 69 are no longer on the same horizontal plane. Reverse connector 2, moving the right-side locking block 69 to the rear of the right-side locking block 67 and the left-side locking block 68 to the front of the left-side locking block 67. Pull connector 2 upwards to separate it from connector 1, thus unlocking connector 1 and connector 2.

[0016] The working principle of the anti-interference fireproof cable connection device provided by this utility model is as follows: When using this anti-interference fireproof cable connection device for cable connection, bring the connecting seat 1 and the connecting seat 2 closer together, insert the connecting end 13 into the vertically adjacent connecting socket 14, at this time, the sealing rubber gasket 15 is inserted into the inside of the extrusion groove and the upper surface of the rubber gasket 15 contacts the inner wall of the extrusion groove. At the same time, the locking block 1 67 and the locking block 2 69 move to the same horizontal plane. At this time, as the connecting seat 1 and the connecting seat 2 approach each other, the lower surface of the connecting seat 2 2 presses the sliding rod 66, causing the sliding rod 66 to move downward, driving the slider 1 64 to move downward. During the downward movement of the slider 1 64, the slider 1 67... 4. Sliding inside the slide groove 63, the upper end of lever 62 moves downward, causing the lower end of lever 62 to move upward, driving slider 2 65 upward. Spring 3 68 contracts, driving block 1 67 upward to move into the mounting groove 2 61. At this time, the upper end of slider 2 65 slides to the upper side of connecting seat 1 and inserts into the mounting groove 10. The upper end of slider 2 65 presses upward against limiting block 12, and spring 2 11 contracts. At this time, connecting seat 2 2 rotates, driving block 2 69 to move, and simultaneously driving mounting groove 10 to move, causing right block 2 69 to move to the front of right block 1 67, and left block 2 68 to move to the rear of left block 1 67. When the mounting slot 10 moves to the upper side of the slide bar 66, the spring 3 68 relaxes, pushing the slider 2 65 downward. The upper end of the slider 2 65 moves into the interior of the connecting seat 2, the spring 2 11 relaxes, the limiting block 12 moves downward, causing the lower end of the lever 62 to move downward, and the upper end of the lever 62 to move upward, driving the slider 1 64 upward. This causes the slide bar 66 to move upward and slide to the upper side of the connecting seat 1, at which point the upper side of the slide bar 66 is located inside the mounting slot 10, and the slide bar 66 is directly below the top block 8, thus connecting the connecting seat 1 and the connecting seat 2. When it is necessary to unlock the connection between the connecting seat 1 and the connecting seat 2, the lever 7 is moved downward, causing the top block 8 to move downward. When the spring 9 relaxes, the top block 8 moves downward to press the slide bar 66, causing the slide bar 66 to move downward into the mounting groove 61. This causes the upper end of the lever 62 to move downward, and the lower end of the lever 62 to move upward, causing the slider 65 to move upward. This causes the locking block 67 to move upward and enter the mounting groove 61. At this time, the locking block 67 and the locking block 69 are no longer on the same horizontal plane. Then, the connecting seat 2 is reversed, causing the right locking block 69 to move to the rear of the right locking block 67, and the left locking block 68 to move to the front of the left locking block 67. At this time, the connecting seat 2 is pulled upward to separate the connecting seat 2 from the connecting seat 1, thereby unlocking the connecting seat 1 and the connecting seat 2.

[0017] 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.
