Description

Technical Field

[0001] The utility model relates to the field of display rack accessories, and particularly relates to a universal connector for a display rack. Background Art

[0002] Most store display racks adopt the AA column structure. Then, a shelf bracket is hung on the AA column, and finally, the shelf is placed on the shelf bracket. To prevent problems such as sliding and falling of the shelf on the shelf bracket, the shelf needs to be fixedly connected to the shelf bracket again through bolts, screws, etc.

[0003] Some display racks not only have shelves but also hanging baskets. The connection method of the hanging basket is similar to that of the shelf. The side of the hanging basket is connected to the shelf bracket through a slide rail assembly, or the side of the hanging basket is connected to the shelf bracket through bolts, screws, etc. In short, whether it is a shelf or a hanging basket, the current AA column requires a shelf bracket as an intermediate connector, and the shelf bracket also needs to be connected to the shelf or the hanging basket again.

[0004] Therefore, the existing shelf brackets not only have a high manufacturing cost but also require secondary connection through bolts, screws, etc., and the installation process is relatively complex. Summary of the Utility Model

[0005] Aiming at the defects in the prior art, in order to replace the shelf bracket structure and adopt a universal connector, the installation process is made easier and simpler. The utility model provides a universal connector for a display rack, which includes a hook and a fastener with a concave cross-section; the hook is fixedly connected to the outer surface of the first side wall of the fastener, and the opening direction of the hook is perpendicular to the opening direction of the fastener; the second side wall of the fastener extends towards the end face of the fastener, and the extended part forms an extension wall; both the second side wall and the extension wall are provided with notches that are consistent with the opening direction of the fastener, and each notch is provided with an anti-disengagement bend.

[0006] The beneficial effect of this device is that: the AA column is provided with one or two rows of longitudinal openings, and the distances between all the openings are equal. The side of the AA column with the opening is also provided with a rib that is adapted to the opening of the fastener. After the second side wall and the extension side wall of the fastener are respectively inserted into two adjacent openings of the AA column and then moved downward, the two anti-disengagement bends are respectively hung on two adjacent openings of the AA column. The hook is hung in the hanging hole of the shelf or the hanging basket. The whole installation process does not require secondary connection to the shelf or the hanging basket through bolts, screws, etc. The installation is simple and the operation is convenient. The whole universal connector has a simpler structure than the existing shelf bracket and requires lower material costs, and also plays the role of an intermediate connector.

[0007] Preferably, the notch of the extension wall is provided with teeth that abut against the outer surface of the AA column. Since the fastener bears the stress of downward fall, the teeth of the extension wall abut against the AA column, playing a role of oblique support and strengthening the connection between the fastener and the AA column.

[0008] Preferably, the widths of the notches of the second side wall and the extension wall are equal, and the width of the notch of the second side wall is not less than the distance between two longitudinally adjacent openings on the AA column. The opening size on the AA column is used as the row label. The notches of the second side wall and the extension wall correspond to the sizes of the existing AA column openings, and there is no size conflict, so it can be applied to most existing AA columns.

[0009] Preferably, the hook and the fastener are integrated, and the material of both is stainless steel.

[0010] Preferably, a locking bolt parallel to the bottom wall of the fastener is provided on the other end face of the fastener, and the end of the locking bolt extends to the notch of the second side wall. The second side wall is provided with a threaded hole adapted to the locking bolt, and the notch of the second side wall is provided with a positioning hole corresponding to the threaded hole. The locking bolt is screwed in so that the end of the locking bolt is inserted into the positioning hole. After the second side wall is buckled into the opening of the AA column and the anti - detachment bend is stuck at the opening of the AA column, then the locking bolt is screwed into the positioning hole, and the locking bolt is locked on the inner side of the side wall between two adjacent openings of the AA column. After being locked, the fastener cannot be separated from the AA column, effectively solving the problem of accidental detachment of the laminate and the hanging basket. In addition, the nut of the locking bolt is provided with anti - slip threads, and the locking bolt can be quickly screwed into the positioning hole by hand - screwing the nut.

[0015] The following will describe in detail the embodiments of the technical solutions of the present invention in conjunction with the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0016] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application shall have the ordinary meanings understood by those skilled in the art to which this utility model belongs.

[0017] As Figure 1 shown, this embodiment provides a universal connector for a display rack, including a hook 1 and a fastener 2 with a concave cross-section. The hook 1 and the fastener 2 are integrated, and the material of both is stainless steel.

[0018] The hook 1 is fixedly connected to the outer surface of the first side wall 11 of the fastener 2, and the opening direction of the hook 1 is perpendicular to the opening direction of the fastener 2. In the figure, the A direction is the opening direction of the fastener 2, and the B direction is the opening direction of the hook 1. Under normal circumstances, the AA column 3 is in a vertical state, and there is a row or two rows of longitudinally distributed openings on the front surface of the AA column 3, and the distance between every two adjacent openings is equal. The fastener 2 is hung on the front surface of the AA column 3 through the opening of the AA column 3, and at the same time, the hook 1 is horizontally upward. By opening hanging holes on the shelf, hanging basket, etc. that are adapted to the hook 1, it is only necessary to hang the hanging holes on the hook 1 to complete the installation of the shelf and the hanging basket. The entire installation process does not require secondary connection with bolts, screws, etc. to the shelf or the hanging basket. The installation is simple and the operation is convenient. The entire universal connector has a simpler structure than the existing shelf support, and the required material cost is lower, and it also plays the role of an intermediate connector.

[0019] In order to adapt to the existing AA column 3 structure, the specific structure of the fastener 2 in this embodiment is as follows:

[0020] The second side wall 12 of the fastener 2 extends towards the end face direction of the fastener 2, and the extended part forms an extension wall 4. Both the second side wall 12 and the extension wall 4 are provided with notches 5 that are consistent with the opening direction of the fastener 2, and each notch 5 is provided with an anti-disengagement bend 6. Specifically, the width of the notch 5 on the second side wall 12 is equal to the width of the notch 5 on the extension wall 4, and the width of the notch 5 on the second side wall 12 is not less than the distance between two longitudinally adjacent openings on the AA column 3. The opening size on the AA column 3 is the industry standard. The notches 5 on the second side wall 12 and the extension wall 4 correspond to the opening size of the existing AA column 3, and there is no size conflict, and it can be applied to most of the existing AA columns 3.

[0021] To prevent the buckle from lifting and falling off from the opening of the AA column 3, in this embodiment, a locking bolt 7 parallel to the bottom wall of the fastener 2 is provided on the other end face of the fastener 2, and the end of the locking bolt 7 extends to the notch 5 of the second side wall 12. The second side wall 12 is provided with a threaded hole adapted to the locking bolt 7, and the notch 5 of the second side wall 12 is provided with a positioning hole 8 corresponding to the threaded hole. The locking bolt 7 is screwed in so that the end of the locking bolt 7 is inserted into the positioning hole 8. After the second side wall 12 is buckled into the opening of the AA column 3 and the anti-drop bend 6 is stuck at the opening of the AA column 3, then the locking bolt 7 is screwed into the positioning hole 8, and the locking bolt 7 is locked to the inner side of the side wall between two adjacent openings of the AA column 3. After being locked, the fastener 2 cannot be separated from the AA column 3, effectively solving the problem of accidental detachment of the laminate and the hanging basket. In addition, the nut of the locking bolt 7 is provided with an anti-slip thread 10, and the locking bolt 7 can be quickly screwed into the positioning hole 8 by hand-tightening the nut.

[0022] As Figure 2 shown, the fastener 2 is buckled on the rib 13 of the AA column 3, and at the same time, the second side wall 12 and the extension wall 4 are inserted into two adjacent openings of the AA column 3. The hook 1 is hung in the hanging hole of the laminate or the hanging hole of the hanging basket. At least one hanging hole is provided on the left and right sides of each laminate. Similarly, the hanging basket is also the same, so as to keep the laminate or the hanging basket balanced. After the fastener 2 bears the weight, the fastener 2 bears the downward stress, and a locking tooth 9 that abuts against the outer surface of the AA column 3 is provided at the notch 5 of the extension wall 4. Since the fastener 2 bears the stress of falling downward, the locking tooth 9 of the extension wall 4 abuts against the AA column 3, playing a role of inclined support and strengthening the connection between the fastener 2 and the AA column 3.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
