Description

Technical Field

[0001] The invention relates to the technical field of steel push-pull rods, in particular to an "S"-shaped steel push-pull rod with a rotating mechanism. Background Art

[0002] When we carry out cargo handling, we usually load the cargo into the box and carry the entire box. When carrying heavier cargo, we usually need to use handling tools to carry it. When carrying cargo at the port terminal, the staff usually use steel push-pull rods with steel wire ropes to carry the cargo. Generally, there are holes at the end of the steel push-pull rods to facilitate the passage of the steel wire ropes. However, some steel push-pull rods still have certain defects in use, such as:

[0003] The utility model publication number is CN217458517U. A steel push-pull rod that prevents falling off is disclosed. When a user uses the steel push-pull rod, the user can rotate the rotating block to drive the worm to rotate. When the worm rotates, it drives the worm wheel meshing with it to rotate, and the worm wheel drives the second limit rod to rotate and separate from the first limit rod. At this time, the rope can be sleeved on the outside of the first limit rod. After that, the user rotates the rotating block in the opposite direction to make the second limit rod engage with the first limit rod. At this time, the process of sleeve and disassembly of the rope by the steel push-pull rod is completed.

[0004] In the above document, after the steel push-pull rod cooperates with the steel wire rope to move the goods to the top of the truck, the user needs to climb onto the truck to remove the steel wire rope from the inside of the push-pull rod, which delays working time and affects work efficiency. In addition, climbing the truck is dangerous for the user, and the steel push-pull rod still needs to be separated from the steel wire rope manually by the user, which is inconvenient.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original steel push-pull rod structure. Summary of the invention

The gear 16 and the arc-shaped clip 12 are symmetrically arranged in two groups about the center point of the protective rod 1.

[0033] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig. 9When using the "S" steel push-pull rod with a rotating mechanism, the user first needs to make the arc-shaped clip 12 located inside the first arc-shaped member 8 and the second arc-shaped member 9, and then make the arc-shaped clip 12 move out from the inside of the first arc-shaped member 8 and the second arc-shaped member 9 and cooperate with the first arc-shaped member 8 and the second arc-shaped member 9 to pass through the knotted wire rope. In this process, the user will control the driving motor 14 to work through the controller 17 and drive the output shaft 15 to rotate. When the output shaft 15 rotates, it will drive the gear 16 to rotate. , and the gear 16 is meshed with the outer surface of the arc-shaped clamping strip 12, thereby driving the arc-shaped clamping strip 12 to move inside the arc-shaped groove 10 and move to the outside of the first arc-shaped member 8 and the second arc-shaped member 9.

After the length of the steel push-pull rod is adjusted, the rotating drum 5 can be rotated to rotate the first arc-shaped member 8, thereby changing the relative position of the first arc-shaped member 8 and the second arc-shaped member 9, thereby effectively improving the applicability of the steel push-pull rod. At this point, the length adjustment process of the steel push-pull rod is completed. The first sealing ring 4, the second sealing ring 7 and the ball 6 can effectively improve the applicability of the length adjustment of the steel push-pull rod. By completing the length of the steel push-pull rod, the convenience of using the steel push-pull rod can be effectively improved, and the overall practicality is increased.
