[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] Example:

[0019] The accompanying drawings illustrate a specific embodiment of the optical cable laying support tripod of this utility model. Figure 1 , Figure 2 It mainly includes a top plate 1, which is made of steel plate. The length and width of the top plate 1 are 18cm and the thickness is 4mm. The bottom of the top plate 1 is provided with three inverted U-shaped rings 2 arranged in a triangle. The inverted U-shaped rings 2 are welded to the top plate 1. Each inverted U-shaped ring 2 has a fixed crossbar 3 at its lower end. Each fixed crossbar 3 is rotatably connected to a connecting plate 4. The connecting plate 4 has a connecting hole 4a. The fixed crossbar 3 passes through the connecting hole 4a. The connecting plate 4 can rotate around the fixed crossbar 3.

[0020] Each connecting plate 4 is fixedly connected to a support pipe 5, which is a steel pipe. The support pipe 5 includes an upper connecting pipe 501 and a lower connecting pipe 502. The upper connecting pipe 501 is slidably inserted into the lower connecting pipe 502, and the lower connecting pipe 502 is provided with a locking bolt 503 to lock and fix the upper connecting pipe 501. The length of the support pipe 5 is adjustable, and the upper connecting pipe 501 can be pulled out or retracted into the lower connecting pipe 502 by turning the locking bolt 503.

[0021] The upper connecting pipe 501 has a slit 501a at its opening, and one corner of the connecting plate 4 is inserted into the slit 501a and fixedly connected to the connecting plate 4 by welding.

[0022] Each support tube 5 has a foot pad 6 at its bottom, which is welded to the lower connecting tube 502. The foot pad 6 is made of steel plate and measures 10cm × 25cm. The foot pad 6 has a positioning opening 6a for engaging with a wooden wedge, allowing the wedge to hold the foot pad 6 in place and prevent the tripod from sliding. The bottom surface of the foot pad 6 also has a rubber anti-slip pad 7 to further increase friction.

[0023] A U-shaped ring 8 is rotatably connected to the center of the bottom of the top plate 1, in conjunction with... Figure 3 The upper end of the U-shaped ring 8 is fixedly mounted on the fixed plate 10. The top of the fixed plate 10 is fixedly connected to the lower connector 11, and the lower connector 11 is rotatably connected to the upper connector 12. The upper connector 12 is fixedly connected to the top plate 1. The U-shaped ring 8 can rotate through the rotational engagement of the upper connector 12 and the lower connector 11.

[0024] A pulley assembly 9 is suspended on the U-shaped ring 8. The pulley assembly 9 is detachably connected to the U-shaped ring 8 and is used to guide the movement of the optical cable. Specifically, the pulley assembly 9 includes a fixed frame 901 and a hook 902 located at the top of the fixed frame 901. The hook 902 is connected to the U-shaped ring 8. Two pulleys 903 arranged vertically are located inside the fixed frame 901, and the optical cable moves through the two pulleys 903. An anti-loosening bolt 904 is threaded onto the hook 902. The hook 902 has a free end and a fixed end. The fixed end is connected to the fixed frame 901, and the anti-loosening bolt 904 passes through both the free end and the fixed end. By tightening the anti-loosening bolt 904, the hook 902 and the U-shaped ring 8 can be connected in a secure manner to prevent detachment.

[0025] When using this tripod, the three support tubes 5 are spread out to form a stable three-point structure. The length of each support tube 5 can be adjusted by tightening the locking bolts 503 to adapt to various terrains. The foot pads 6 welded to the bottom of the tripod increase the contact area with the ground, preventing sinking on soft ground. The rubber anti-slip pads 7 on the bottom of the foot pads 6 further increase friction. The positioning openings 6a on the foot pads 6 can be used with wooden wedges to lock the foot pads 6 and prevent the tripod from sliding. The pulley assembly 9 at the bottom of the tripod top plate 1 can be replaced according to the actual diameter of the optical cable to be laid. To replace it, simply tighten the anti-loosening bolts 904, remove the hooks 902 from the U-shaped rings 8, and replace it with a suitable pulley assembly. During optical cable laying, the optical cable moves between two pulleys 903. The U-shaped rings 8 can rotate, allowing the pulleys 903 to change direction, thus the laying direction of the optical cable is adjustable.
