Description

Technical Field

[0001] This utility model relates to the technical field of shelf node protection equipment, and more specifically to a shelf node protection sleeve. Background Technology

[0002] Shelf nodes are critical load-bearing components. Impact damage to these nodes can cause shelf tilting or detachment, leading to goods slipping and collapsing. This can result in minor damage to goods or, in severe cases, a chain reaction of collapses, expanding the scope of losses. With the booming development of modern manufacturing and logistics, forklifts are increasingly used in warehousing. However, due to various driver-related reasons, forklift collisions, scrapes, or crushing of shelves are frequent. Therefore, designing a new type of shelf node protection device has become extremely important.

[0003] Currently, there is virtually no protective structure at the connection between warehouse racking uprights and beams. The most common approach is to protect the racking uprights, and occasionally use tape to bind foam at the connection between the upright and beam. However, this method of protection is easily damaged and very inconvenient.

[0004] Therefore, providing a sleeve with a simple structure and reasonable design that can protect the connection nodes between the uprights and beams on warehouse shelves is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a protective sleeve for the connection nodes of the shelving nodes, which has a good protective effect on the connection nodes of the uprights and beams on the shelving.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective sleeve for shelving nodes, installed at the connection between uprights and beams, includes a cylindrical body and elastic support plates. The cylindrical body has a clearance opening along its length and a through-hole corresponding to the beam, the through-hole communicating with the clearance opening. The elastic support plates include two elastic arm plates and a buffer connecting plate located within the cylindrical body. The two elastic arm plates are arranged facing each other, and the buffer connecting plate is fixedly connected to one side of the two elastic arm plates, forming a U-shape between them. The U-shaped groove has its opening corresponding to the clearance opening. The column can be accommodated in the U-shaped groove through the clearance opening. The buffer connecting plate provides elastic buffering when the two elastic arm plates are subjected to force and approach each other. The ends of the two elastic arm plates away from the buffer connecting plate are fixed and abut against the inner wall of the cylinder to provide elastic support for the inner wall of the cylinder. The elastic arm plate has an assembly opening corresponding to the through opening. The crossbeam passes through the through opening and is fixedly connected to the assembly opening.

[0008] Through the above technical solution, this utility model discloses a protective sleeve for rack nodes. When the outer wall of the sleeve is impacted by a forklift or other external force, the sleeve is stressed and tends to dent. Elastic arm plates elastically support the inner wall of the sleeve, applying a spring force opposite to the deformation direction to buffer the deformation. When the two elastic arm plates are stressed and approach each other, they compress the buffer connecting plate, compressing it and applying a spring force opposite to the movement direction to the elastic arm plates, causing them to return to their original position. This protective sleeve for rack nodes has a simple structure and reasonable design, providing good protection for the connection nodes between uprights and beams on racks, effectively mitigating the impact of external forces on the nodes.

[0009] Preferably, the cross-section of the buffer connecting plate is wavy.

[0010] Preferably, the buffer connecting plate has at least two protrusions on one side corresponding to the column.

[0011] Preferably, the cylinder, the elastic arm plate, and the buffer connecting plate are all made of plastic material with a Rockwell hardness between 100 and 120 degrees and an elastic modulus between 800 MPa and 1200 MPa.

[0012] Preferably, the lengths of the cylinder, the elastic arm plate, and the buffer connecting plate are equal, and the length range is 300mm-900mm.

[0013] Preferably, the through-hole is a square opening with a length of 100mm-200mm. Attached Figure Description

A U-shaped groove is formed between 21, and the opening of the U-shaped groove is arranged corresponding to the clearance opening 11. The column 100 can be accommodated in the U-shaped groove through the clearance opening 11. The buffer connecting plate 22 provides elastic buffering when the two elastic arm plates 21 are subjected to force and approach each other. The side ends of the two elastic arm plates 21 away from the buffer connecting plate 22 are fixed and abut against the inner wall of the cylinder 1 to provide elastic support for the inner wall of the cylinder 1. The elastic arm plate 21 is provided with an assembly opening 211 corresponding to the through opening 12. The crossbeam 200 passes through the through opening 12 and is fixedly connected to the assembly opening 211.

[0028] In this embodiment, the device is installed on the connection node between the outer upright 100 and the crossbeam 200 of the shelf.

The elastic arm plate 21 applies an elastic force to the cylinder 1 in the opposite direction of deformation. When the two elastic arm plates 21 are subjected to force and approach each other and press against the buffer connecting plate 22, the buffer connecting plate 22 is compressed and applies an elastic force to the elastic arm plate 21 in the opposite direction of movement, so that the elastic arm plate 21 returns to its original position.

[0030] Specifically, the cross-section of the buffer connecting plate 22 is wavy, and the buffer connecting plate 22 has at least two protrusions on one side corresponding to the column 100.

[0031] Specifically, the cylinder 1, the elastic arm plate 21, and the buffer connecting plate 22 are all made of plastic material with a Rockwell hardness between 100 and 120 degrees and an elastic modulus between 800 MPa and 1200 MPa.

[0032] Specifically, the lengths of the cylinder 1, the elastic arm plate 21, and the buffer connecting plate 22 are equal, and the length ranges from 300mm to 900mm.

[0033] Specifically, the opening 12 is a square opening with a length of 100mm-200mm.
