Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to a quantitatively adjustable pull rod device. Background Art

[0002] The tensioning device can effectively pull the deformed and displaced structure back to its original position. Currently, it mostly adopts a stud bolt with two nuts. The nuts are welded to the two ends of the pull rod respectively, and the stud bolt is screwed into the nut. The pull rod is extended or shortened by manually rotating the bolt. This method has the disadvantage that the adjustment amount cannot be quantified, and it needs to be measured with a ruler to restore the structure to its initial state. Utility Model Content

[0003] In view of the defects existing in the prior art, the purpose of the utility model is to provide a quantitatively adjustable pull rod device, which can easily restore the structure to the initial state with the help of a power rod.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a quantitatively adjustable pull rod device is arranged in a car, and the pull rod device includes a basket bolt, a power rod and two pull rods; two fixed sockets are relatively arranged on the inner walls on both sides of the car; the two ends of the basket bolt are respectively connected to the proximal ends of the two pull rods, and the distal ends of the two pull rods are respectively connected to the corresponding fixed sockets; the power rod includes a rod body, and a rectangular head is arranged at the front end of the rod body, which is used to insert the basket bolt and drive it to rotate to adjust the length of the pull rod. At the same time, it can also be used to determine whether the pull rod has returned to the initial length.

[0005] Further improvements are: the basket bolt includes a frame and two screw rods; nuts are fixedly arranged on both sides of the frame; the proximal ends of the screw rods cooperate with the corresponding nut threads and extend into the frame, and a gap is formed between the proximal ends of the two screw rods for the rectangular head of the assisting rod to be inserted; the distal end of the screw rod is hinged to the corresponding pull rod through a U-shaped joint; when the pull rod returns to its initial length, the proximal ends of the two screw rods are pressed against the surface of the rectangular head of the assisting rod.

[0006] A further improvement is that the two pull rods have different lengths, one of the pull rods is a long rod and the other is a short rod.

[0007] A further improvement is that a positioning pin is provided at the rear end of the rod body.

[0008] A further improvement is that the fixed card seat includes a card, the card is fixedly connected to the carriage through a pad, and a card slot matching the shape of the pull rod is provided on the card.

[0009] A further improvement is that a blocking piece is provided at the distal end of the pull rod, and the pad is provided with a slot matched with the blocking piece.

[0010] A further improvement is that the rectangular head is a rectangular hollow frame structure.

[0011] The beneficial effects of the utility model are:

[0012] The utility model does not need to use a ruler to check during adjustment. By observing whether the rectangular head of the power-assisting rod can be inserted and the gap between the two bolt heads after insertion, it can be easily judged whether the pull rod has returned to the initial length, thereby realizing the function of quantitatively and accurately resetting the displacement structure.
