Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and in particular to a shelf support structure. Background Technology

[0002] Shelves are devices used for displaying and showcasing goods. They are widely used in retail stores, supermarkets, shopping malls, showrooms, and other places. They not only display goods and showcase functions, but also effectively optimize space layout, improve space utilization, attract customer attention, promote sales, and thus better convey brand information.

[0003] A search revealed that patent CN209436752U discloses a shelving unit, including shelving uprights and shelving units mounted on the uprights. The shelving units are connected to the uprights via T-shaped connectors. However, during use, it was found that the T-shaped connectors, located near the uprights, only serve a connecting function and do not provide stable support for the units. This results in poor stability of the shelving unit during use, limiting the amount of items that can be placed on it. Utility Model Content

[0004] To address the lack of support structure for existing shelving shelves, this invention provides a shelf support structure. By setting crossbeams on the four sides of the shelf, the shelf can be stably supported. At the same time, the cooperation of locking plates and positioning pins can stabilize the shelving and ensure that the entire frame does not swing or twist.

[0005] This utility model provides a shelf support structure, including columns and shelves mounted on the columns. A crossbeam is provided between two adjacent columns, and the crossbeam is fixedly connected to the columns by locking plates at both ends. The shelves are supported on the crossbeam. The crossbeam not only connects and stabilizes adjacent columns, but also provides stable support for the shelves.

[0006] Furthermore, the lock plate is equipped with a hook, and the post has a hanging hole that matches the hook. The lock plate is fixed to the post by the cooperation of the hook and the hanging hole.

[0007] Furthermore, the hook includes a hanging plate and a hook plate, which are L-shaped. The hanging plate is placed in the hanging hole, and the hook plate extends into the post and is parallel to the post. The side of the hook plate closest to the post is also provided with a positioning protrusion. The positioning protrusion ensures that the hook, once hooked, will not become loose from the post.

[0008] Furthermore, the crossbeam is a hollow tube with an upper tube plate and a lower tube plate. The lower tube plate of the crossbeam has a through hole to accommodate a locking plate. The locking plate, which is hung on the column, extends into the crossbeam through the through hole and abuts against the upper tube plate of the crossbeam. The locking plate extending into the crossbeam provides limiting support for the crossbeam.

[0009] Furthermore, the locking plate includes a locking main plate and two side plates, which are U-shaped. Hooks are set on the side plates, and the upper part of the locking plate is placed in the through hole. Each side plate is provided with two hooks, and the hanging holes on the column are opened accordingly. That is, there are four sets of hooks and hanging holes, which provides good stability.

[0010] Furthermore, a locating pin is provided at the lower part of the locking plate, and the locking main board is fixedly connected to the column through the locating pin. The locating pin further locks the locking plate, column, and crossbeam.

[0011] Furthermore, the positioning pin is an indexing pin, comprising a pin body, a spring, and a pin seat. The pin seat has a pin hole at its center through which the pin body can pass. The pin body is movably positioned within the pin seat by the spring. The locking main plate has a mounting hole for installing the pin seat, and the column has a positioning hole that matches the pin body. The pin body, elastically positioned within the pin seat, abuts against the positioning hole, thus securing the locking plate and the column.

[0012] Furthermore, a nut is provided on the side of the locking main board away from the column, with the nut's threaded hole opposite the mounting hole. The pin seat has external threads that mate with the nut's threads. The pin body has a pin head at the end near the positioning hole and a cap at the end away from the positioning hole. The pin seat has a receiving cavity to accommodate the pin head, and a spring is fitted around the pin body and placed inside the receiving cavity. Pulling the cap extends or retracts the pin head, thus locking and releasing the positioning pin.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model provides a shelf support structure. By setting a crossbeam between adjacent columns, it can not only connect and stabilize the columns, but also provide stable support for the shelves. At the same time, locking plates are set at both ends of the crossbeam to further limit the crossbeam and the columns, ensuring that the entire shelf does not swing or twist after connection, thus improving the stability during use.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0023] To achieve a stable connection to column 1 and provide stable support for shelf 2, a shelf support structure is designed, such as... Figure 1 and 2 As shown, the structure includes uprights 1 and shelves 2 mounted on the uprights 1. A crossbeam 3 is installed between two adjacent uprights 1. The crossbeam 3 is fixedly connected to the uprights 1 by locking plates 4 at both ends. The shelves 2 are mounted on the crossbeam 3. The shelves 2 are divided into length and width directions. The crossbeam 3 is usually directly fixed between the two uprights 1 in the width direction with bolts. The locking plates 4 are located below the shelves 2 in the length direction for limiting and supporting them.

[0024] like Figure 3 As shown, the locking plate 4 is provided with a hook 41, and the column 1 is provided with a hanging hole 11 that matches the hook 41. The vertical length of the hanging hole 11 is slightly larger than the length of the hook 41, so that the hook 41 can be directly inserted into the hanging hole 11 and fastened to the hanging hole 11 under the action of gravity. In order to prevent the hook 41 from loosening between the fastened hook 41 and the column 1, the hook 41 includes a hanging plate and a hook plate, which are L-shaped. The hanging plate is placed in the hanging hole 11, and the hook plate extends into the column 1 and is parallel to the column 1. The side of the hook plate near the column 1 is also provided with a positioning protrusion 411, which abuts against the inner wall of the column 1 for limiting.

[0025] like Figure 5 As shown, in order to limit and fix the structure of the beam 3 and the column 1 to prevent the shelf from twisting, the beam 3 is a hollow tube with an upper tube plate 31 and a lower tube plate 32. The lower tube plate 32 of the beam 3 has a through hole 33 that can accommodate the locking piece 4. The locking piece 4, which is hung on the column 1, extends into the beam 3 through the through hole 33 and abuts against the upper tube plate 31 of the beam 3 to ensure that the beam 3 and the column 1 are perpendicular.

[0026] like Figure 4 As shown, the locking plate 4 includes a locking main plate and two side plates, and is U-shaped. Hooks 41 are set on the side plates, and the upper part of the locking plate 4 is placed in the through hole 33. The U-shaped locking plate 4 has a larger support area and better support stability. In order to further ensure the stable connection between the locking plate 4 and the column 1, a positioning pin 5 is provided at the lower part of the locking plate 4, and the locking main plate is fixedly connected to the column 1 through the positioning pin 5.

[0027] like Figure 5 As shown, specifically, the positioning pin 5 is an indexing pin, including a pin body 51, a spring 52 and a pin seat 53. The center of the pin seat 53 has a pin hole through which the pin body 51 can pass. The pin body 51 is movably set in the pin seat 53 by the spring 52. The locking main plate has a mounting hole for installing the pin seat 53, and the column 1 has a positioning hole 12 that matches the pin body 51. A nut 42 is provided on the side of the locking main plate away from the column 1. The nut 42 is welded to the locking main plate, and the screw hole of the nut 42 is opposite to the mounting hole. The pin seat 53 has an external thread that mates with the thread of the nut 42. The pin seat 53 can be fixed to the locking main plate by the engagement of the nut 42 and the pin seat 53. The end of the pin body 51 near the positioning hole 12 has a pin head 54, which is integrally formed with the pin body 51. The end of the pin body 51 away from the positioning hole 12 has a cap 55, which is screwed onto the end of the pin body 51. Pulling the cap 55 can cause the pin head 54 to extend or retract. The pin seat 53 has a accommodating... The receiving cavity 56 of the pin head 54 is fitted with a spring 52 which is sleeved outside the pin body 51 and placed inside the receiving cavity 56. The diameter of the pin head 54 is larger than the diameter of the pin body 51 and smaller than the inner diameter of the receiving cavity 56. The spring 52 is fixedly set between the pin head 54 and the bottom wall of the receiving cavity 56. During installation, the cap 55 is pulled outward first, so that the pin head 54 compresses the spring 52 and retracts into the receiving cavity 56. After the locking main plate is hung on the column 1, the cap 55 is released. Under the spring action of the spring 52, the pin head 54 extends out of the receiving cavity 56 and abuts into the positioning hole 12 on the column 1, thereby completing the fixing of the locking plate 4 and the column 1.
