When installing and laying optical fibers, cable burying racks are often used. Fiber optic cable burying racks are a device used to install and maintain optical fiber cables, and are used to protect and support optical fiber cables.

[0003] The existing optical fiber cables are passed through the threading holes into the cable burying frame, which is generally an integrated structure. When the optical fiber cables inside the cable burying frame need to be maintained, the optical fiber cables need to be pulled out from the cable burying frame for maintenance. After the optical fiber cables are maintained, they need to be inserted into the cable burying frame one by one, which makes the maintenance of the optical fiber cables more troublesome.

[0024] like Figures 1 to 7As shown, the optical fiber buried cable rack of this embodiment is easy to maintain, including a buried cable rack 1, a protective shell 2 is detachably installed on the top of the buried cable rack 1, and the protective shell 2 plays a role in protecting the photovoltaic cable inside the buried cable rack 1. The surfaces of both sides of the buried cable rack 1 are provided with a plurality of threading holes 5, and the photovoltaic cables can pass through the buried cable rack 1 through the threading holes 5. Two plug holes 6 are provided on both sides of the top of the buried cable rack 1, and first grooves 7 are provided inside the buried cable rack 1 on both sides of the plug holes 6. A sliding rod 8 is connected inside the first groove 7, and a limiting rod 9 is sleeved on the outer side of one end of the sliding rod 8. A first spring 10 is sleeved on the outer side of the sliding rod 8 between the limiting rod 9 and the first groove 7. Two insertion rods 11 are connected to the edges of both sides of the bottom end of the protective shell 2. Limiting holes 12 are provided on both side surfaces of the lower part of the insertion rod 11, and two sliding grooves 21 are provided on both sides of the front and rear ends of the buried cable frame 1. The end face of the limiting rod 9 is connected to a push rod 22, and one end of the push rod 22 passes through the sliding groove 21 and extends to the outside of the buried cable frame 1. When the photovoltaic cable inside the buried cable frame 1 needs to be maintained, the push rod 22 is pulled away from the insertion rod 11, and the push rod 22 drives the limiting rod 9 to move toward the insertion rod 11 until one end of the limiting rod 9 moves out from the limiting hole 12, so that the insertion rod 11 can move inside the socket 6, and then the protective shell 2 is removed from the top of the buried cable frame 1, thereby facilitating the maintenance of the photovoltaic cable inside the buried cable frame 1 and improving the efficiency of the maintenance of the photovoltaic cable inside the buried cable frame 1.

[0025] Specifically, a plurality of slots 13 are equidistantly provided on the outer surface of the wire embedding frame 1 on both sides of the wire threading hole 5, and a plurality of plug blocks 14 are equidistantly connected to the front and rear edges of the lower surface of the protective shell 2, and the plug blocks 14 match the slots 13, so that the stability of the connection between the wire embedding frame 1 and the protective shell 2 is improved by the slots 13 and the plug blocks 14.

[0026] Furthermore, the cable burying frame 1 is internally connected to a base 3, and a plurality of arc grooves 4 are equidistantly provided at the top of the base 3, and the arc grooves 4 extend along the width direction of the base 3, so that the optical fiber cables can be conveniently separated through the arc grooves 4 to avoid the entanglement of too many optical fiber cables; a plurality of connecting rods 15 are connected to the bottom end of the protective shell 2 between the two rows of plug-in blocks 14, and a second groove 16 is provided at the bottom end of the connecting rod 15, and a movable rod 17 is slidably connected inside the second groove 16, and the bottom end of the movable rod 17 extends to the outside of the connecting rod 15, and one end of the movable rod 17 can move up and down inside the second groove 16 through the second groove 16; an arc clamping plate 18 is connected to the extending end of the connecting rod 15, and the arc clamping plate 18 is fixed to the outer wall surface of the photovoltaic cable by contacting the outer wall surface of the photovoltaic cable, and a rubber pad 19 is connected to the inner side of the arc clamping plate 18, and the rubber pad 19 prevents the photovoltaic cable from being clamped by the arc clamping plate 18 and damaged.

[0027] Furthermore, a second spring 20 is connected inside the second groove 16 at the top of the movable rod 17. Two second springs 20 are provided. The top of the second spring 20 is connected to the top of the inside of the second groove 16. During the rebound process of the second spring 20, the movable rod 17 is driven to move downward together with the arc-shaped clamping plate 18.

[0028] The method of using this embodiment is as follows: first, the photovoltaic cable is passed through the buried wire frame 1 through the threading hole 5, and the photovoltaic cable is located inside the arc groove 4, which is convenient for separating the optical fiber cables to avoid the entanglement of too many optical fiber cables. First, pull the push rod 22 in the direction away from the insertion rod 11, and the push rod 22 drives the limiting rod 9 to move to the inside of the first groove 7. At this time, the first spring 10 is in a compressed state, and the four insertion rods 11 at the bottom end of the protective shell 2 are inserted into the four insertion holes 6 corresponding to the top of the buried wire frame 1, and the protective shell 2 is installed on the top of the buried wire frame 1, and several insertion blocks 14 at the bottom end of the protective shell 2 are respectively inserted into the corresponding slots 13, and the stability of the connection between the buried wire frame 1 and the protective shell 2 is improved by the slots 13 and the insertion blocks 14. When the protective shell 2 is installed, release the force of pulling the push rod 22. During the rebound process of the first spring 10, it drives one end of the limiting rod 9 to move to the inside of the insertion hole 6 and insert it into the limiting hole 12, so that the insertion rod 11 is fixed inside the insertion hole 6. During the installation process of the protective shell 2, the protective shell 2 drives the arc groove 12. The card plate 18 moves downward, and the arc card plate 18 contacts the outer wall surface of the photovoltaic cable to fix it. When the diameter of the photovoltaic cable becomes larger, the arc card plate 18 drives the movable rod 17 to move into the second groove 16. When the diameter of the photovoltaic cable becomes smaller, the second spring 20 generates a rebound force, and the rebound force drives the movable rod 17 to move downward. The movable rod 17 drives the arc card plate 18 to move downward directly until the arc card plate 18 contacts the outer wall surface of the photovoltaic cable to fix it, so that photovoltaic cables of different diameters can be fixed by the arc card plate 18. When it is necessary to maintain the photovoltaic cable inside the buried wire rack 1, the push rod 22 is pulled away from the insertion rod 11, and the push rod 22 drives the limit rod 9 to move in the direction of the insertion rod 11 until one end of the limit rod 9 moves out from the inside of the limit hole 12, so that the insertion rod 11 can move inside the insertion hole 6, and then the protective shell 2 is removed from the top of the buried wire rack 1, thereby facilitating the maintenance of the photovoltaic cable inside the buried wire rack 1 and improving the efficiency of the maintenance of the photovoltaic cable inside the buried wire rack 1.
