In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application.

[0023] Reference Figure 1 , Figure 2The shown embodiment is: a kind of optical fiber slot for easy fixing mainly by installation base 1 constitutes core support component, the upper surface of installation base 1 is provided with two sliding side plates 2 along its length direction, the sliding action of relative close or relative far away can be realized on installation base 1 by the two sliding side plates 2, and they are completely symmetrical distribution relative to the center line of installation base 1, to this end ensure that different number and diameter optical fiber can provide suitable accommodation and constraint space, in the four corner positions of installation base 1, respectively design with the structure of detachable connection with external mounting frame 3, each mounting frame 3 is processed into metal frame with certain strength and shape, multiple mounting holes 4 are opened on its surface along different directions, so as to be firmly fixed on the external support structure such as wall, cabinet and the like by bolt using mounting frame 3, at the same time, in the four corner parts of installation base 1, a second sliding block 5 is also slidably connected, the quick connection between these second sliding blocks 5 and corresponding mounting frame 3 is realized through buckle mechanism 6, in order to further improve the flexibility and accuracy of optical fiber slot installation, a set of adjusting mechanism 7 specially used for fine adjustment of the position of second sliding block 5 is also provided on installation base 1, this adjusting mechanism 7 can accurately change the position of second sliding block 5 on installation base 1 according to actual installation environment and demand, so as to realize the fine adjustment of the overall installation position of optical fiber slot, ensure that optical fiber slot can be accurately installed in predetermined position, meet various complex installation scenes and high-precision installation requirements.

[0024] In the above embodiment, installation base 1 is generally made of plastic or metal material with certain strength and stability, such as aluminum alloy or engineering plastic, sliding side plate 2 can be selected from materials with hard texture and smooth surface, such as stainless steel sheet or hard plastic plate, which can effectively constrain optical fiber and prevent it from moving randomly in the slot, reduce the friction between optical fiber and side plate, and protect the outer skin of optical fiber from damage, mounting frame 3 is generally made of high-strength metal material, such as steel or aluminum alloy, to ensure that it has sufficient rigidity and carrying capacity to stably support optical fiber slot and optical fiber inside it, sliding side plate 2 on installation base 1 realizes relative or opposite sliding action through guide rail structure or recess and protrusion matching mode, which enables sliding side plate 2 to flexibly adjust the spacing according to the actual situation of optical fiber, when thicker optical fiber or more optical fiber is needed, sliding side plate 2 can be slid to both sides to increase the accommodation space, and when the optical fiber is thinner or the number is less, the side plate can be slid inward to allow the optical fiber to be closely arranged, avoiding shaking and entangling in the slot, thereby effectively protecting the transmission performance of optical fiber and improving the adaptability and compatibility of optical fiber slot to different specifications of optical fiber.

[0025] Referring to Figure 1 , Figure 2 , Figure 5The embodiment shown is that the internal structure of the mounting base 1 is specifically that a through cavity, i.e., a through cavity 8, is formed in the middle of the length direction, a sliding groove 9 that communicates with the through cavity 8 is formed at the top of the mounting base 1 corresponding to the position of the through cavity 8, two first sliding blocks 10 are slidingly connected in the through cavity 8 and correspond to the two sliding side plates 2 respectively, and the first sliding blocks 10 can slide along the width direction of the mounting base 1 in the through cavity 8, the top of the first sliding block 10 extends from the sliding groove 9 and is fixed as a whole with the corresponding sliding side plate 2 at the bottom by welding, riveting or bolt connection, and a first rotating screw 11 that can rotate around its own axis is transversely rotatably connected in the mounting base 1, the thread parts on the two sides of the screw are opposite in rotation direction and are connected with the corresponding first sliding blocks 10 by tight thread cooperation, in this embodiment, the through cavity 8 provides a stable sliding space for the first sliding blocks 10, reduces external interference and ensures sliding accuracy; the sliding groove 9 ensures effective connection of the first sliding blocks 10 with the sliding side plates 2 and limits the vertical displacement thereof, so that the first sliding blocks 10 can only slide horizontally; the first rotating screw 11 is made of metal (such as stainless steel) and has sufficient strength and wear resistance, can stably transmit power and bear thread friction.

[0026] The implementation principle of the above embodiment is that when the first rotating screw 11 is rotated, the first sliding blocks 10 will move linearly in opposite or opposite directions according to the thread transmission principle because the threads on the two sides of the first rotating screw 11 are opposite in rotation direction, for example, when it is rotated clockwise, the left first sliding block 10 moves to the left and the right first sliding block 10 moves to the right, and vice versa, the effect of this connection relationship is that the distance between the sliding side plates 2 can be accurately controlled by rotating the first rotating screw 11, the operation is simple and the adjustment accuracy is high, compared with the traditional structure, the cost is reduced, the adjustment efficiency and flexibility are improved, different optical fiber specifications can be quickly adapted, and the practicability and universality of the optical fiber slot are improved.

[0027] Referring to Figure 6 The embodiment shown is that a worm wheel 12 is fixed to the middle of the first rotating screw 11 inside the mounting base 1, the two are coaxially arranged to ensure synchronous rotation, a worm 13 that can rotate around its own axis is rotatably connected at the bottom of the mounting base 1, forming a worm wheel 12 worm 13 transmission mechanism, the worm 13 penetrates along the thickness direction of the mounting base 1 at the bottom and is fixed with a handle 14 at the extending end, the handle 14 is designed into a shape (such as a circle, a square, etc.) that is convenient to hold and force and has anti-slip lines (such as rubber protrusions or frosted treatment) on the surface.

[0028] The implementation principle of the above embodiment is as follows: the operator rotates the handle 14 to drive the worm 13 to rotate. Through the meshing action of the worm 13 and the worm wheel 12, the worm wheel 12 and the coaxial first rotating screw 11 are driven to rotate. Since the transmission ratio of the worm wheel 12 and worm 13 is large, it can achieve speed reduction and torque increase. The operator can generate a large torque on the first rotating screw 11 with a small force when rotating the handle 14, which overcomes the friction between the first sliding block 10 and the screw and the moving resistance of the sliding side plate 2, and realizes the adjustment of the side plate spacing. The effect of this connection relationship is that, on the one hand, it makes it easier for the operator to adjust the side plate spacing, improves the convenience and comfort of operation, and reduces labor intensity; on the other hand, the worm wheel 12 and worm 13 transmission has a self-locking characteristic, which can prevent the first rotating screw 11 from rotating accidentally, ensure the stability of the sliding side plate 2 spacing, and thus ensure that the fixed state of the optical fiber is not disturbed, thereby improving the reliability and stability of optical fiber transmission.

[0029] Reference Figure 5 One embodiment shown is as follows: a groove 15 is formed on one side surface of the second sliding block 5 along a specific direction (such as the length or width direction). The groove 15 has a trapezoidal or semi-circular cross section, and its size is precisely matched with the shape of the sliding block 17. A sliding cavity 16 is machined inside the mounting bracket 3 corresponding to the position of the groove 15. Its shape and size match the sliding block 17 to provide it with sliding space. The sliding block 17 is placed in the sliding cavity 16 and maintains an appropriate gap with the cavity wall to ensure smooth sliding. A compression spring 18 is fixedly connected to one side of the sliding block 17, and the other end of the compression spring 18 is fixed to the inner wall of the sliding cavity 16. The axis of the compression spring 18 is parallel to the sliding direction of the sliding block 17.

[0030] The implementation principle of the above embodiment is as follows: when the mounting base 1 is close to the mounting bracket 3, the second sliding block 5 pushes the sliding block 17 to slide into the sliding cavity 16 to compress the spring 18. When the slot 15 is aligned with the block, the spring 18 pops the block into the slot 15 to achieve a snap-fit ​​connection.

[0031] Reference Figure 2 , Figure 5 One embodiment shown is as follows: The adjustment mechanism 7 is specifically configured such that a second rotating screw 19, which can rotate around its own axis, is rotatably connected to both ends of the mounting base 1. The threaded portions on both sides of the screw have opposite directions of rotation and are respectively connected to the corresponding second sliding blocks 5 through threaded tight engagement. A friction part 20 is provided in the middle of the second rotating screw 19, such as a friction ring made of rubber or a rough texture processed on the surface of the screw, so as to facilitate the operator to apply force when manually rotating the screw.

[0032] The principle of the above embodiment is that when the position of the mounting base 1 on the mounting frame 3 needs to be finely adjusted, the operator manually rotates the second rotating screw 19, and due to the opposite screw rotation directions on the two sides, according to the screw transmission principle, the second sliding block 5 will move relatively or oppositely along the axis direction of the screw under the action of the screw, thereby driving the mounting base 1 to realize accurate adjustment of the position.

[0033] The working principle of the device is that during the optical fiber laying process, first, the mounting frame 3 is fixed on the predetermined position through the mounting hole 4 on the mounting frame 3, and according to the actual situation of the optical fiber, such as the diameter and the number, the spacing of the sliding side plate 2 is adjusted by the adjusting mechanism 7 on the mounting base 1, so that the optical fiber can be placed in the optical fiber groove in an orderly manner, then the optical fiber groove is quickly and preliminarily installed on the mounting frame 3 through the second sliding block 5 on the four corners of the mounting base 1 and the buckle mechanism 6 on the mounting frame 3, and if it is found during the installation process that the position of the optical fiber groove needs to be finely adjusted, the adjusting mechanism 7 on the mounting base 1 can be used to rotate the second rotating screw 19 to accurately adjust the position of the mounting base 1 on the mounting frame 3.

[0034] The working principle of the device has been described in the above embodiment, and the above embodiment only expresses several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
