Description

Technical Field

[0001] The utility model relates to the technical field of shelves, in particular to a shelf heightening connector. Background Art

[0002] A shelf is a type of storage rack for users to place and store items on. Shelves are widely used in various industries. Typically, a shelf consists of columns, beams, and storage boards. After assembly, the ends of the beams are fixed to the adjacent columns, and the storage boards are placed directly on or fixed to the beams. The distance between any adjacent beams can be adjusted based on different usage needs, so that different storage spaces are formed between adjacent storage boards for users to store items of different sizes. One of the characteristics of a shelf is that it occupies a very small volume before assembly, making it easy to transport or carry. On the one hand, the size of the shelf before assembly is often determined by the size of the columns. On the other hand, the height of the shelf after assembly is also determined by the size of the columns. Generally speaking, the length of the columns must be suitable not only for transportation but also for use. Precisely because of this limitation, the use of shelves often requires splicing two or more columns together to extend the height of the shelf in the assembled state, thereby facilitating use.

[0003] Connectors are important components for connecting columns. On the one hand, connectors can not only structurally connect two columns, but also ensure the strength of the two columns after being connected. In this way, the overall strength and stability of the shelf can be ensured.

[0004] Chinese patent application number 201510035459.X discloses a connector, a shelf with a connector, and a method, wherein the connector is used to connect two columns and includes a fixed body; and at least one connecting body, wherein a mounting cavity is formed between the fixed body and each connecting body to allow the ends of each column to be installed simultaneously in the mounting cavity, and the fixed body and the connecting body are respectively located on different sides of each column. Although the above patent can achieve the purpose of raising the column height, the shelf is prone to tipping accidents due to center of gravity problems when it is high, which is unsafe. Existing connectors cannot solve this problem. In addition, for shelf columns with a double-layer structure, the gap between the double-layer boards varies due to different material thicknesses. After installation, connectors with fixed thickness are prone to large gaps, easy movement, and loose connections. If the fixing ears are directly welded to the outside of the connector, the thin material thickness makes welding very inconvenient and the product consistency is poor. Utility Model Content

[0005] The utility model proposes a shelf heightening connector in order to solve the above problems.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A shelf heightening connector comprises a main body part whose ends are plugged and fixed to columns, a wall fixing part is plugged into the middle of the main body part, the cross-section of the main body part is a right angle, a transverse groove is formed in the middle of the main body part near the right angle, the wall fixing part comprises a plug-in plate plugged into the transverse groove, the plug-in plate is fixed together with the main body part, a first limiting part is formed on one side of the plug-in plate, and a second limiting part is formed on the other side of the plug-in plate, a fixing slot hole is formed on the first limiting part, and the first limiting part and the second limiting part are 2-3 mm away from the main body part.

[0008] Furthermore, the thickness of the main body is 1-3 mm.

[0009] Furthermore, a limiting hole is formed at the lower end of a side wall of the main body away from the first limiting member.

[0010] Furthermore, the thickness of the plug board is 1-4 mm.

[0011] Furthermore, the first limiting member, the second limiting member, and the plug-in board are perpendicular to each other.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 4 As shown, a shelf heightening connector includes a main body 1 with both ends plugged into and fixed to the columns. The main body 1 is made of stainless steel and has a thickness of 1 mm. A wall fixing member 2 is plugged into the middle of the main body 1. The cross section of the main body 1 is a right angle. A transverse groove 11 is formed in the middle of the main body 1 near the right angle. The wall fixing member 2 includes a plug-in board 21 plugged into the transverse groove 11. The plug-in board 21 is fixed to the main body 1. A first limiter 22 is formed on one side of the plug-in board 21, and a second limiter 22 is formed on the other side of the plug-in board 21. The second limiting member 24 and the first limiting member 22 are formed with a fixing slot 23, which is convenient for fixing the connecting member to the wall, or the two connecting members are fixed together. The first limiting member 22, the second limiting member 24, and the plug-in board 21 are perpendicular to each other. The distance between the first limiting member 22 and the second limiting member 24 and the main member 1 is 3 mm. When connecting the shelf columns, the first limiting member 22 and the second limiting member 24 can be against the outer wall of the column to provide lateral support force and reduce the risk of deformation of the column below the plug-in board 21.

[0022] In this embodiment, a limiting hole 12 is formed at the lower end of the side wall of the main body 1 away from the first limiting member 22. The limiting hole 12 corresponds to the position of the adjustment hole on the shelf column. The connecting member and the shelf column can be fixed together by passing a bolt through the limiting hole 12 to improve stability.

[0023] In this embodiment, the plug board 21 has a thickness of 2 mm, is strong, has a strong load-bearing capacity, and is not easily damaged.

[0024] The working principle of the utility model is as follows: when in use, the upper and lower ends of the two shelf columns are respectively inserted into the upper and lower ends of the main body 1, and the ends of the columns are pressed against the upper and lower end surfaces of the plug-in plate 21. Then, bolts are passed through the outside of the columns and fixed in the limiting holes 12. The nuts are tightened to fix the main body 1 and the lower shelf columns together. Then, expansion bolts are passed through the fixing slots 23 to fix the shelf to the wall or connect two shelves back to back into one, thereby improving stability.

[0025] Components not described in detail herein are prior art.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
