It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0032] In the description, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance. It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, removable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms based on specific circumstances.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 2 As shown, a split folding stacking positioning pin device includes a tapered pin body 1, an upper base 2, a lower base 6, a pin shaft sleeve 3 and a countersunk bolt. The tapered pin body 1 is connected to a rotating shaft 5, and a protruding frustum is provided at the bottom of the tapered pin body 1.

[0036] The upper surface of the upper base 2 is provided with a circular sunken platform that matches the round cone. The upper base 2 and the front and / or rear surfaces of the lower base 6 are jointly provided with a circular sunken platform that matches the round cone. Four countersunk holes are provided at the four corners of the upper surface of the upper base 2, and the lower base 6 is provided with threaded holes corresponding to the countersunk holes. The four countersunk bolts pass through the countersunk holes of the upper base 2 and are fixedly connected with the threads of the lower base 6.

The centers of the circular sinks can penetrate each other and leak out the rotating shaft 5. The lower base 6 is fixedly installed on the stacking ribs of the packaging box. The lower base 6 is generally fixed to the stacking ribs of the packaging box by welding, riveting or screws.

[0038] The utility model further includes two positioning pins 4. The surfaces of the upper base 2 and the lower base 6 on both sides jointly form a circular hole for accommodating the rotating shaft 5. Through holes for the positioning pins 4 are provided at both ends of the rotating shaft 5. Blind holes for the positioning pins 4 are provided along the radial direction of the circular holes of the upper base 2 and the lower base 6. The positioning pins 4 can constrain the rotation of the rotating shaft 5 and can also be used to quickly locate the position of the upper base 2, facilitating the rapid positioning of the upper base 2 and the lower base 6 and facilitating installation of the utility model.

[0039] It should be noted that the fixed connection method of the upper base 2 and the lower base 6 with the rotating shaft 5 in this embodiment is not the only one. For example, a keyway method can also be used for connection.

[0040] The taper pin body 1 is provided with a knurling in the middle, a groove for holding is provided above the knurling, and the top of the taper pin body 1 is a conical head.

The pin shaft sleeve 3 includes a pin shaft part and a sleeve part. The pin shaft part is provided with an external thread. The sleeve part can be sleeved on the rotating shaft 5 and has a clearance fit with the rotating shaft 5 so that the sleeve part can rotate along the rotating shaft 5. When used, the vertical position and horizontal position of the conical pin body 1 can be converted by rotating the pin shaft sleeve 3, thereby realizing the folding function of the utility model.

[0042] There is a gap 1 between the two symmetrical parts of the upper base 2 after installation, and the pin shaft part can pass through the gap 1 of the upper base 2. The lower base 6 is provided with a gap 2 for the pin shaft part to rotate. In this embodiment, the circular sink can be used as a reference for tightening the tapered pin body 1.

[0043] A circular boss is provided at one end of the rotating shaft 5 , and both side surfaces of the upper base 2 and the lower base 6 jointly form a stepped circular hole for accommodating the rotating shaft 5 .

[0044] The normal operation steps are as follows Figures 3 to 7 As shown, first rotate the taper pin body 1 to unscrew it from the pin shaft part, so that the bottom cone is spaced apart from the circular sink formed by the upper base 2 and the lower base 6, then rotate the pin shaft sleeve 3 to a vertical position, and then tighten the taper pin body 1.

[0045] During maintenance and replacement, rotate the tapered pin body 1 to unscrew it from the pin shaft part, so that the bottom cone is distanced from the circular sink on the upper surface of the upper base 2, remove the 4 countersunk bolts on the upper base 2, and take out the upper base 2, take out the rotating shaft 5 and remove the locating pin 4, and finally replace the corresponding parts.
