Description

Positioning structure of tripod stand for folding rack

The present invention relates to a stand-up positioning structure of a foldable shelf. The structure design of the stand frame and the stand is mainly used to ensure a stable buckle positioning and maintenance during stand-up. When the frame is stacked, the stacking relationship can be firmly maintained, and the excellent practical value can be given accordingly.

According to the conventional metal shelf, the shelf surface is mainly made of metal mesh frame surrounded by the metal frame edge, and a pair of pivot holes are formed on both sides of the frame edge to provide another ㄩ-shaped tripod. The plug-in card is fixed to form a proper support for its storage surface, and at the same time, the tripod has a foldable and retractable function to reduce its storage and packaging volume.

In order to maintain the stability of the stand when it is unfolded, it is usually tied to punch out protruding card bumps on both sides of the frame, and match the horizontal section formed by folding the card end of the stand to expand the stand. Immediately, the horizontal section of the frame must be clamped and positioned by the protruding points of the frame edge to maintain the stand state of the stand.

However, the stand-and-stand fixing method of the above-mentioned shelf only uses the protruding card protrusions on the frame edge to form a contact-type positioning relationship with the horizontal section of the card insertion end of the stand. The stability is obviously insufficient and it is easy The tripod is out of the positioning state due to external force, causing the tripod to collapse suddenly and causing the rack to collapse, causing the items placed on it to fall and be damaged. Furthermore, this type of rack lacks a positioning structure, resulting in its When the shelf is stacked in layers, it is easy to collapse and fall due to lack of positioning, which seriously affects its overall practical value, and it is necessary to solve the improvement.

In view of the many problems and deficiencies of the existing metal shelf tripods that fail to provide a stable and fixed position effect during the exhibition, the inventor specially developed and improved, based on his years of experience and technology in related industries, and then developed The tripod positioning structure of the present invention.

In the design of the positioning structure of the tripod stand, the present invention is mainly provided with a pair of pivot holes and a pair of clamping slots at both ends of the metal frame of the rack, and the pair of pivot holes are used A separate ㄩ-shaped tripod card assembly can be provided separately, and it can be folded and retracted. The two card ends of these ㄩ-shaped tripods are folded into a horizontal positioning part. The part is equipped with inwardly facing buckle protrusions, so that when the tripod is in the extended state, the buckle protrusions can be inserted into the clamping slots on the frame side to obtain the stand-up state of the tripod. To maintain the stable fixed position of the rack, a micro-shaped buckle frame is also set on the top surface of the two sides of the aforementioned shelf, so as to cooperate with the convex frame part of the lower end of the tripod folded outwards, so that the two shelf When making up and down stacking assembly, the tripod convex frame part of the upper shelf can be inserted into the buckle frame of the lower shelf to obtain the stable maintenance of the stacked state.

The present invention is aimed at the stand positioning structure designed for the folding rack. Through the improved design of the structure, the stand folding and retracting function is maintained, and the stand and the rack frame can be obtained when the stand is unfolded. The embedded buckle card positioning relationship on the side greatly improves the stability of the stand stand. At the same time, when the rack is stacked up and down, it can also achieve an excellent relationship positioning and maintenance, thereby greatly improving its industry Those of usability and practical value.
