Abstract
Description
Technical Field
[0001] This utility model belongs to the field of folding stacking pin technology, specifically relating to a folding stacking pin mechanism. Background Technology
[0002] Existing folding stacking pins mainly consist of a stacking pin seat, a pin shaft, a union bolt, and a tapered pin body. When the stacking pin needs to be folded, the tapered pin body must be loosened from the union bolt, then rotated 90°, and then tightened again. The same procedure applies when the stacking pin needs to be erected. During installation, over-tightening can easily occur, causing the tapered pin body to detach and resulting in problems such as lost parts.
[0003] There is an urgent need to develop a new folding stacking pin mechanism to simplify the operation process, shorten the installation time, and enable convenient storage and retrieval of stacking pins. Utility Model Content

[0008] Preferably, one end of the pin is provided with a large flange and the other end is provided with an annular groove; the large flange is located in a transverse through hole A on one side and is padded with a flat washer, and the annular groove is located in a transverse through hole A on the other side and is equipped with an elastic retaining ring.
[0009] Preferably, the lower end face of the tapered pin protrudes to form a limiting ring seat, and the upper end face of the open rotating cavity of the stacking pin seat is provided with a limiting groove A adapted to place the limiting ring seat; the limiting ring seat is located in the limiting groove A to limit the tapered pin body in an upright state; the side end face of the open rotating cavity of the stacking pin seat is provided with a limiting groove B adapted to place the limiting ring seat, and the limiting ring seat is located in the limiting groove B to limit the tapered pin body in a horizontal state.
[0010] Preferably, the lower end face of the tapered pin is provided with a positioning groove, and the tapered pin is assembled onto the mounting boss through the positioning groove.
[0011] Preferably, a compression spring is fitted onto the bolt; the compression spring is located between the bolt head and the bottom surface of the bolt cavity, and the compression spring is in a compressed state under normal conditions.
[0012] The installation process of the folding stacking pin mechanism described in this utility model is as follows:
[0013] First, place the rotating connector in the open rotating cavity of the stacking pin seat, and align the transverse through hole B of the rotating connector with the transverse through hole A on the side wall of the stacking pin seat. Then, insert the pin into the hole, insert a flat washer into the large flange side of the pin, and seal the annular groove with an elastic retaining ring.
[0014] Then, place the tapered pin on the rotating connector, so that the mounting boss on the top of the rotating connector is inserted into the positioning groove below the tapered pin.
[0015] Finally, place the compression spring into the bolt cavity at the top of the tapered pin; then, thread the bolt through the compression spring into the threaded hole at the top of the rotating connector and tighten it to complete the installation.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This utility model's folding stacking pin mechanism allows for the rapid erection and lowering of stacking pins without cumbersome operations, simplifying the installation and usage process.
