[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a waterproof optical fiber connection box of the utility model comprises a box body 1 and multiple optical fibers 8, both ends of the box body 1 in the width direction are thickened to form a wiring part 2, a groove 17 is provided on the wiring part 2, a sealing block 4 is provided inside the groove 17, a plurality of first wiring grooves 7 are provided on the bottom surface of the sealing block 4, a second wiring groove 6 is provided on the bottom surface of the groove 17 opposite to the first wiring groove 7, the first wiring groove 7 and the second wiring groove 6 are combined to form a wiring channel, the optical fibers 8 are arranged through the wiring channel, a plurality of first arc grooves 15 are provided on the inner wall surface of the first wiring groove 7, a plurality of second arc grooves 18 are provided on the inner wall surface of the second wiring groove 6, the first arc groove 15 and the second arc groove 18 are combined to form an annular groove, and a positioning ring 16 is installed at the optical fiber 8 opposite to the annular groove.

[0023] In this embodiment, a plurality of slide grooves 9 are provided on the inner side surface of the wiring portion 2, and the slide grooves 9 are respectively arranged at the two ends of the groove 17. Slide blocks 12 are slidably installed in the slide grooves 9, and baffles 10 are installed on one side surface of the slide blocks 12. One end of the baffles 10 extends to the inner side of the sealing block 4 and blocks the wiring channel where the optical fiber 8 is not arranged. The slide blocks 12 are provided with screw holes that penetrate the slide blocks 12 and the baffles 10, and the screw holes are threadedly connected with hand bolts 11 that lock and fix the slide blocks 12 in the slide grooves 9.

[0024] In this embodiment, the cross-sections of the slider 12 and the slide groove 9 are both arranged in a trapezoidal structure, so that the baffle can only move laterally along the slide groove, thereby preventing the slider from detaching from the slide groove.

[0025] In this embodiment, positioning grooves 13 are vertically provided at both ends of the groove 17, and both ends of the sealing block 4 protrude to form positioning parts 5, which are slidably set in the positioning grooves 13. Compression springs 14 are installed on the bottom surfaces of the positioning parts 5, and the other ends of the compression springs 14 are installed on the bottom surfaces of the positioning grooves 13; when the box cover is opened, the sealing block can be bounced upward by the compression spring, so that the sealing block and the groove are in an open state, which facilitates the entry and exit of the optical fiber.

[0026] In this embodiment, the sealing blocks 4 are all arranged to protrude from the top surface of the wiring portion 2, so that the sealing blocks can be pressed down during the closing process of the box cover.

[0027] In this embodiment, a box cover 3 for opening or sealing the box body 1 is installed on one side of the box body 1 .

[0028] In this embodiment, the positioning ring 16 is made of rubber material, which improves the sealing performance, and the positioning ring can be disposed in contact with the inner side surface of the annular groove.

[0029] In this embodiment, the inner diameter of the wiring channel matches the diameter of the optical fiber 8, so that the first wiring groove and the second wiring groove can be in close contact with the outer wall surface of the optical fiber to ensure the sealing between the two.

[0030] When in use, the optical fiber can pass through the corresponding wiring channel. Before the box cover is closed, the positioning part and the sealing block can be lifted upward by the rebound of the compression spring, so that the sealing block and the groove are in an open state, and the space between the first wiring groove and the second wiring groove is in an open state, so that the optical fiber can pass smoothly. After the optical fiber is inserted into place, the positioning ring on the optical fiber can be inserted into the first arc groove at the lower end first to pre-position the optical fiber. After the optical fiber is installed, the box cover can be closed. During the closing process, the sealing block can be pressed down, and the optical fiber can be pressed by the descending sealing block, and the upper half of the positioning ring can be inserted into the second arc groove of the sealing frame, and a close and gapless contact is formed by the positioning ring and the annular groove. This design effectively reduces the possibility of medium leakage because the leakage path is blocked by the concave-convex structure.

[0031] Among them, before the box cover is closed, the wiring channel where the optical fiber is not installed can be blocked. The operation process is to move the baffle and move it along the slide groove until the baffle moves to the inner side of the wiring channel and blocks the opening on the inner side of the wiring channel. After the position is determined, the hand bolt can be rotated so that one end of the hand bolt can be against the inner wall surface of the slide groove, thereby locking and fixing the moved baffle.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
