DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figure 1 , the utility model provides a technical solution: an optical cable line fixing device.

[0025] Among them, a movable groove 204 is opened at the center position of the support plate 2, and an adjusting screw 203 is installed longitudinally inside the movable groove 204. Two movable bases 301 are installed on the surface of the screw 203. The top of the movable base 301 is fixedly connected to a fixed plate 3, and a plurality of optical cable holes 302 are opened on the surface of the fixed plate 3.

[0026] In this embodiment, there are three fixed plates 3, and the bottom is installed on the movable base 301. The openings of the optical cable through holes 302 on each fixed plate 3 are all facing both sides, and a gap is left between each fixed plate 3 to facilitate the insertion of the optical cable into the optical cable through hole 302. The overall fixed plate 3 cooperates with the movable base 301 and there are a total of two pieces, one in front and one in the back, installed above the support plate 2. The bottom of the movable base 301 extends into the movable groove 204 and is provided with a threaded hole. The threaded rod 203 passes through the threaded hole and engages with the thread on the threaded hole. By rotating the threaded rod 203, the movable base 301 can drive the three fixed plates 3 to move on the support plate 2, and adjust the distance between the front and rear fixed plates 3, thereby changing the length of the overhead optical cable.

[0027] Among them, a one-way baffle 303 is installed near the outer side of the fixed plate 3 at the optical cable through hole 302, a torsion spring 305 is arranged at the bottom of the one-way baffle 303 near the inner side of the optical cable through hole 302, and a stopper 304 is arranged at the top of the one-way baffle 303 near the outer side of the optical cable through hole 302, and the stopper 304 is fixedly connected to the fixed plate 3.

[0028] In this embodiment, the bottom of the one-way baffle 303 is fixed by an axis so that it can flip over in the optical cable perforation 302, and the front end is blocked by the stop block 304 to prevent flipping to the outside, and the bottom is forced by the torsion spring 305 to make the front end fit on the stop block 304 and keep the optical cable perforation 302 closed. When the optical cable perforation 302 needs to be opened, the one-way baffle 303 is flipped inward to press the torsion spring 305 to open the optical cable perforation 302 and insert the optical cable, and then the one-way baffle 303 closes the optical cable perforation 302 through the torsion spring 305 to prevent the optical cable perforation 302 from being accidentally opened and the optical cable from detaching.

[0029] Among them, an adjusting screw 101 is installed longitudinally through the inside of the shell 1 near the bottom surface, two slides 102 are installed through the surface of the adjusting screw 101, a rotating seat 104 is fixedly connected to the top of the slide 102 near the left and right sides, a lifting rod 105 is rotatably installed at the center of the rotating seat 104, a rotating seat 202 is installed on the top of the lifting rod 105, and the rotating seat 202 is fixedly connected to the bottom of the support plate 2.

[0030] In this embodiment, two slides 102 are arranged at the bottom of the shell 1, and a threaded hole is opened in the center of the slide 102. The adjusting rod 101 passes through the two threaded holes. Through the engagement of the threads, the adjusting rod 101 can be rotated to drive the two slides 102 to move. The rotating seat 104 on the slide 102 and the rotating seat 202 at the bottom of the support plate 2 are in the same longitudinal direction. The two are connected by a lifting rod 105, and the two lifting rods 105 in the same longitudinal direction are staggered in an X shape, and an opening is passed through the middle to avoid collision. When the two slides 102 approach each other, the lifting rod 105 rises and lifts the support plate 2, thereby raising the fixing plate 3 to prevent the two slides 102 from moving away from each other and the fixing plate 3 from being lowered, thereby changing the fixed height of the optical cable.

[0031] Among them, the adjusting screw rod 101 and the adjusting screw rod 203 are both double-headed screw rods.

[0032] In this embodiment, the thread directions of the two ends of the double-headed screw are opposite, so that the threaded holes with the same thread will move in opposite directions when meshing with the double-headed screw, thereby achieving opposite movement directions between the two fixed plates 3 and between the slide plates 102, and changing the spacing.

[0033] Wherein, limit plates 103 are arranged on the top of the left and right sides of the slide plate 102 , and the limit plates 103 are fixedly connected to the inner wall of the shell 1 .

[0034] In this embodiment, the slide plate 102 is inserted into the gap between the limiting plate 103 and the bottom of the housing 1, so that the slide plate 102 will not flip when it moves by rotating the adjusting screw 101, and the movement is more stable.

[0035] The housing 1 is provided with a movable hole 106 at the top center position in the extending direction of the adjusting screw 101 .

[0036] In this embodiment, the front ends of the adjusting screw 101 and the adjusting screw 203 extend out from the front ends of the outer shell 1 and the support plate 2, and anti-slip sleeves are covered on the surface. The device is adjusted by rotating by the operator. The extension direction of the adjusting screw 203 is the outer shell 1. A movable hole 106 is opened on the outer shell 1 to prevent the adjusting screw 203 from colliding with the outer shell 1.

[0037] Wherein, T-shaped grooves 201 are provided on both sides of the moving groove 204 at the top of the support plate 2 .

[0038] In this embodiment, a T-shaped boss is provided under the movable base 301, and the boss is embedded in the T-shaped slot 201 to assist the entire movable base 301 to move, prevent the fixed plate 3 from tipping over during movement, and make the overall movement more stable.

[0039] Working principle: Turn the adjusting screw 101, through the meshing of the threads, turn the adjusting rod 101 to drive the two slides 102 to move toward the center, the lifting rod 105 rises and lifts the support plate 2 through the rotating seat 202, so that the fixed plate 3 is raised, and the height of the fixed plate 3 is adjusted. Turn the adjusting screw 203, and the two movable bases 301 drive the fixed plate 3 to move on the support plate 2, and adjust the distance between the front and rear fixed plates 3. Insert a single optical cable into the corresponding optical cable perforation 302 in turn, and the one-way baffle 303 is pressed on the stop block 304 by the torsion spring 305 to close the optical cable perforation 302 to prevent the optical cable from detaching, and separate the multiple optical cables originally bundled together. It is also more convenient for subsequent staff to sort the optical cables, thereby improving the overall work efficiency.
