Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: an optical cable tension fitting string, including a pre-twisted tension clamp 4, a right-angle hanging plate 3 installed on the left side of the pre-twisted tension clamp 4, an adjusting plate 2 installed on the left side of the right-angle hanging plate 3, two U-shaped hanging rings 1 provided on the left side of the adjusting plate 2, the two U-shaped hanging rings 1 being interlocked, the right U-shaped hanging ring 1 being connected to the adjusting plate 2, and a GD hanging plate 9 installed on the left side of the left U-shaped hanging ring 1. The adjusting plate 2 includes a plate body 204, a fixing hole 205 opened at the top of the plate body 204, an arc-shaped groove 209 opened at the left side of the fixing hole 205 at the top of the plate body 204, a plurality of limiting holes 201 opened in the inner outer ring of the arc-shaped groove 209, an arc-shaped limiting strip 203 provided inside the arc-shaped groove 209, the rear end of the arc-shaped limiting strip 203 passing through the inner and outer side walls of the arc-shaped limiting strip 203 of the plate body 204 and contacting the inner and outer rings of the arc-shaped groove 209 respectively. The inner ring of the groove 209 has a spring groove 207, and a compression spring 208 is fixed inside the spring groove 207. The other end of the compression spring 208 is fixed to a fixing block 211. The fixing block 211 and the arc-shaped limiting strip 203 are fixedly connected. The pre-twisted tension clamp 4 has an inner pre-twisted wire 5 inside, and an optical cable 6 inside the inner pre-twisted wire 5. The distance between the multiple limiting holes 201 and the fixing holes 205 decreases from front to back, which facilitates the adjustment of the distance between the right-angle hanging plate 3 and the U-shaped hanging ring 1. The left end of the arc-shaped groove 209 has an insertion hole 210, which allows the arc-shaped limiting strip 203 to be inserted into the insertion hole 210, preventing the bolt from squeezing the arc-shaped limiting strip 203 from the inside of the frontmost limiting hole 201. A ground wire clamp 7 is installed on the outside of the optical cable 6, and a ground wire 8 is installed inside the ground wire clamp 7, which protects the equipment, prevents static electricity accumulation, and prevents lightning damage.

[0023] Furthermore, both the top and bottom of the arc-shaped limiting strip 203 are fixed with levers 202, which facilitates the movement of the arc-shaped limiting strip 203. The levers 202 are made of steel. A magnetic strip 206 is fixed inside the right side of the arc-shaped groove 209. The magnetic attraction of the magnetic strip 206 is greater than the elastic force of the compression spring 208, which can restrict the movement of the arc-shaped limiting strip 203.

[0024] During operation, multiple mechanisms are connected by bolts and nuts. The bolt installed between the right-angle hanging plate 3 and the adjusting plate 2 is located inside the fixing hole 205, and the bolt installed between the right-side U-shaped hanging ring 1 and the adjusting plate 2 is located inside the limiting hole 201. When it is necessary to adjust the distance between the right-angle hanging plate 3 and the U-shaped hanging ring 1, the finger moves the lever 202, which can move the arc-shaped limiting strip 203. This facilitates the movement of the arc-shaped limiting strip 203. After the lever 202 and the arc-shaped limiting strip 203 move to the rear, the magnetic strip 206 attracts the lever 202, thus opening the limiting hole 201. The bolt located inside the limiting hole 201 is moved out and then moves into the interior of other limiting holes 201. The distance between each limiting hole 201 and the fixing hole 205 is different, thus completing the adjustment. After the adjustment is completed, the arc-shaped limiting strip 203 returns to its original position and closes the limiting hole 201, preventing the bolt from moving out of the limiting hole 201. It is simple and convenient.
