[0002] In the field of industrial warehousing and logistics, heavy-duty racking is the core equipment for storing large and heavy palletized goods, and its core load-bearing component is the beam. The beam is usually made of high-strength steel (such as cold-rolled steel) and is installed horizontally between the racking uprights, directly bearing the weight of the pallets and goods. Its structural strength, stability, and ease of installation directly determine the load-bearing capacity, safety, and operational efficiency of the racking system.

[0003] Traditional heavy-duty shelving beams are mostly rigid, integral structures with fixed lengths, and are connected to the uprights by hooks or bolts at the ends.

[0004] However, existing heavy-duty rack beams have the following technical defects in practical applications:

[0005] Fixed-length beams lack adjustability, making it difficult to accommodate storage locations of varying depths. This limits warehouse space utilization and increases inventory costs. Furthermore, rigid beams occupy significant space during transport, resulting in high logistics costs. Assembly, especially at heights, is extremely labor-intensive, involving the handling, lifting, positioning, and installation of long and heavy beams. Summary of the Invention

[0040] The following description, with reference to the accompanying drawings, describes the folding beam structure of a retractable heavy-duty shelving unit that is one embodiment of the present invention.

[0041] Please refer to Figures 1-5 As shown, a folding beam structure for a telescopic heavy-duty rack includes a main body 1, which is used as a beam. The number of main bodies 1 is set to two, and they are connected by a connecting part that can rotate and lock.

[0042] A telescopic part is provided at the end of any one of the main bodies 1 that is away from the other main body 1;

[0043] Regarding subject 1, among which...

[0044] Main body 1 is set as a hollow rectangular tube;

[0045] Several reinforcing holes 101 are embedded in the outer wall of the main body 1;

[0046] Specifically, the reinforcing hole 101 adopts a "triangular" and / or "circular" (not shown) through hole to provide additional stress resistance to the body 1;

[0047] Regarding the connecting parts, they are configured as a first connecting part and a second connecting part, wherein...

[0048] The first connecting part includes,

[0049] The connecting sleeve 3 is a round tube with an internal thread 3-1 on its inner wall. There are two connecting sleeves 3, which are installed at the opposite ends of the two main bodies 1 respectively.

[0050] Specifically, the connecting sleeve 3 is fixedly connected to its corresponding main body 1, and the fixed connection method is welding, riveting or screwing.

[0051] The connecting pipe 301 is a round pipe whose outer diameter is adapted to the inner diameter of the connecting sleeve 3, and its outer wall is provided with an external thread 301-1 adapted to the internal thread 3-1 of the inner wall of the connecting sleeve 3.

[0052] In use, when the axes of the two main bodies 1 are on the same straight line, rotate the connecting pipe 301. The connecting pipe 301 is displaced within the connecting sleeve 3 until the connecting pipe 301 simultaneously connects the two connecting sleeves 3 on the two main bodies 1, thus completing the fixed connection.

[0053] More specifically, a support plate 301-2 is provided inside the connecting pipe 301, and a connecting post 301-3 colinear with the axis of the connecting pipe 301 is provided on the support plate 301-2;

[0054] The function of the support plate 301-2 and the connecting column 301-3 is to facilitate the rotation of the connecting pipe 301 by the operator. That is, the operator can install bolts at the end of the connecting column 301-3 to facilitate the rotation of the connecting column 301-3, thereby driving the support plate 301-2 and the connecting pipe to rotate.

[0055] The second connecting part includes,

[0056] The limiting groove 103 is embedded in the outer wall of the end of the main body 1 near the other main body 1;

[0057] The limiting groove 103 is set as an "L" shaped groove.

[0058] When the two main bodies 1 are collinear on the axis, the ends of the two corresponding "L"-shaped grooves are connected to form a "U"-shaped groove;

[0059] The outer wall of the main body 1 is provided with several corresponding limiting grooves 103;

[0060] The limiting rod 103-1 is set as a "U" shaped rod, which is adapted to the limiting groove 103;

[0061] When in use, when the two main bodies 1 rotate to the point where their axes are collinear, the two corresponding limiting grooves 103 connect. At this time, the limiting rod 103-1 is inserted into the limiting groove 103 to further fix the two main bodies 1 and enhance the stress-resistant embedded end of the crossbeam.

[0062] Regarding the telescopic part, including,

[0063] Telescopic block 2 is disposed at any end of main body 1;

[0064] The telescopic block 2 and its corresponding main body 1 are slidably connected by the telescopic column 201;

[0065] The telescopic column 201 is set as a square tube that fits the inner wall of the main body 1;

[0066] The main body 1 includes a mounting ear 203 provided inside the reinforcing hole 101;

[0067] Specifically, the telescopic column 201 is provided with a number of grooves 202, and the inner wall of the main body 1 is provided with a number of protrusions that are adapted to the grooves 202. The grooves 202 and the protrusions are used to slide and limit the telescopic column 201 and the main body 1.

[0068] In use, the operator passes the fastening screw / bolt (not shown in the figure) through the mounting ear 203 until the fastening screw hits the telescopic column 201, thereby fixing the main body 1 and the telescopic column 201, and thus fixing the main body 1 and the telescopic block 2. That is, the length of the main body 1 can be adjusted by the telescopic block 2, the telescopic column 201, the mounting ear 203 and the fastening screw.

[0069] Normal usage status

[0070] When using crossbeams:

[0071] The staff rotated the two main bodies 1 to make their axes collinear, and fixed them by connecting pipe 301 and connecting sleeve 3. Further fixation was achieved based on limiting groove 103 and limiting rod 103-1, which improved the stress-resistant embedded end of the main body 1. Moreover, the telescopic block 2 and telescopic column 201, which can be telescopically adjusted, were used to realize the telescopic adjustment of the crossbeam main body 1, which is convenient to use.

[0072] When the crossbeam needs to be folded (before transportation, movement, or assembly):

[0073] The workers rotated the two main bodies 1 until their axes were parallel, and fixed them by screwing bolts and nuts into the corresponding two mounting ears 203. They also adjusted the telescopic block 2 connected to either main body 1 to fit against the main body 1, i.e., at the minimum travel of the telescopic part, so as to obtain the minimum space occupation and facilitate the handling, transportation and movement of the crossbeam main body 1.

[0074] Compared with the prior art, this utility model has the following characteristics:

[0075] Based on the fixing of the connecting sleeve 3 and the connecting pipe 301, as well as the limiting groove 103 and the limiting rod 103-1, the stress resistance of the main body of the crossbeam 1 is improved, and the use process is convenient.

[0076] The main body 1 is equipped with telescopic blocks 2, telescopic columns 201 and mounting ears 203 to achieve telescopic adjustment, so as to adapt to different heavy-duty rack assembly environments.

[0077] It is equipped with a pivot 102 and mounting ears 203, which enables the main body 1 to be folded, making it convenient for storage, transportation and assembly.

[0078] This utility model is not limited to any particular implementation method; various modifications can be made as long as the principle is not violated.
