After welding, the rubber sleeve is moved to the welding position, and then the rubber sleeve is hot-melted to connect it to the optical cable. However, this method will cause stress on the welding points of the two optical cables when the two ends of the optical cable are pulled by external force, causing the optical cables to be damaged and separated from each other. Therefore, an optical cable repair node protection device is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-6 A fiber optic cable maintenance node protection device comprises a lower arc buckle 1, a connecting block 3 arranged relatively to the surface of the lower arc buckle 1 is fixedly connected, an upper arc buckle 5 is arranged above the lower arc buckle 1, a clamping block 6 arranged relatively to the surface of the upper arc buckle 5 is fixedly connected, the clamping block 6 and the connecting block 3 are connected by a clamping assembly (the clamping assembly connects the upper arc buckle 5 and the lower arc buckle 1 together), the clamping assembly comprises a clamping block 4 fixedly connected to the top of the connecting block 3, a notch matched with the clamping block 4 is provided at the top of the clamping block 6, and an installation groove is provided on the surface of the upper arc buckle 5.

[0022] Furthermore, a hidden groove is provided at one end of the locking block 4, in which a trapezoidal limit block 401 is slidably connected (the trapezoidal limit block 401 fixes and limits the locking block 6, thereby making the connection between the lower arc buckle 1 and the upper arc buckle 5 stable), and a limiting spring 402 is fixedly connected between one side of the hidden groove and one end of the trapezoidal limit block 401.

[0023] It should be noted that: the two ends of the upper arc buckle 5 are fixedly connected with the upper arc ring 501, the two ends of the lower arc buckle 1 are fixedly connected with the lower arc ring 101, and the inner surface of the lower arc buckle 1 is fixedly connected with the sponge board 2 (the sponge board 2 has the characteristics of elasticity and increased friction, so that the optical cable is clamped tighter).

[0024] It is worth noting that: an extrusion fixing assembly is arranged in the installation groove (the extrusion fixing assembly fixes the plastic outer skin of the optical cable), the extrusion fixing assembly includes a screw rod 7 arranged in the installation groove, a nut block 702 threadedly connected to the screw rod 7 is fixedly connected in the installation groove, and a T-shaped grip 701 is fixedly connected to the top of the screw rod 7 (the screw rod 7 drives the arc-shaped clamping plate 9 to move downward through the T-shaped grip 701 to squeeze and fix the optical cable);

[0025] The bottom end of the screw rod 7 is rotatably connected to a movable plate 8, the bottom end of the movable plate 8 is fixedly connected to a relatively arranged fixed block, and the bottom end of the fixed block is fixedly connected to an arc-shaped clamping plate 9 (the arc-shaped clamping plate 9 squeezes and fixes the optical cable).

[0026] A further advantage of adopting the above is that the above device prevents both ends of the optical cable from being pulled by external forces, thereby preventing the welding point of the two optical cables from being stressed, thereby preventing the optical cables from being damaged and separated from each other.

[0027] When the utility model is in use: after the staff has welded the two optical cables together, the staff will place the lower arc buckle 1 on the surface of the plastic outer skin of the optical cable, and then the staff will connect the upper arc buckle 5 with the lower arc buckle 1. When the upper arc buckle 5 drives the clamping block 6 to move down to the clamping block 4, the staff will continue to move the upper arc buckle 5 downward, so that the clamping block 6 squeezes and pushes the trapezoidal limit block 401, and pushes the trapezoidal limit block 401 into the inside of the clamping block 4. When the upper arc buckle 5 fits with the lower arc buckle 1, the clamping block 6 loses the squeezing force on the trapezoidal limit block 401. At this time, the limit spring 402 pushes the trapezoidal limit block 401 to reset, and clamps the clamping block 6, so that the upper arc buckle 5 and the lower arc buckle 1 are connected together. At this time, the upper arc ring 501 fits with the lower arc ring 101 to form a circular groove, and the circular groove fits with the plastic outer skin of the optical cable.

[0028] Then the staff holds the T-shaped handle 701 and rotates it. The rotation of the T-shaped handle 701 drives the screw rod 7 to rotate and move downward. The downward movement of the screw rod 7 drives the movable plate 8 to move downward. The downward movement of the movable plate 8 drives the two arc-shaped clamping plates 9 to move downward. The two arc-shaped clamping plates 9 move downward to squeeze and fix the plastic outer skins of the two optical cables, so that the two layers of plastic outer skins move downward and are engaged in the sponge board 2. The optical cable is fixed to the sponge board 2 through the arc-shaped clamping plates 9. The above device avoids the two ends of the optical cable from being pulled by external force, thereby avoiding the stress on the welding point of the two optical cables, and further avoiding the optical cables from being damaged and separated from each other.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
