AI Technical Summary
Existing folding turnover boxes have insufficiently robust connection structures when transporting heavy items, which can easily cause items to scatter and make it difficult to prevent soup leakage. Insufficient overall strength and connection strength also affect their service life.
The frame base plate is made of high-strength thermoplastic and is formed by square posts and slots of long and short side plates. The frame base plate is designed with anti-slip ribs. The long and short side plates are connected by snap-fit. The frame base plate is formed by thermoplastic molding to form slots and openings to snap-fit with the side plates.
It achieves stable loading, is easy to fold and carry, enhances overall strength and connection strength, and extends the service life of the turnover box.

Abstract
Description
Technical Field
[0001] This utility model relates to a turnover box, and more particularly to a folding turnover box. Background Technology
[0002] Folding turnover boxes are increasingly used for the turnover of fruits, cooked food, vegetables and other food products. They can protect the transported items well. However, the existing connection mechanism between the long and short side panels and the base is not strong enough. When transporting heavy items, the connection structure is not strong enough, and the loaded items may fall out.
[0003] In daily life, people often need to carry or store foods containing broth, such as cooked food, stews, and braised dishes. While traditional folding baskets are easy to fold and carry, they often fail to effectively prevent broth leakage, causing inconvenience. Therefore, there is an urgent market need for a new type of folding box that maintains both portability and prevents leakage. Furthermore, the overall strength and connection strength of existing turnover box bases are still insufficient, affecting their overall lifespan. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a foldable turnover box that can be used to store solid or semi-liquid items, is easy to fold and carry, and has good overall strength and connection strength.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a folding turnover box, including a side frame and a frame base plate. The side frame is spliced together by a pair of parallel long side plates and a pair of parallel short side plates. The long side plates and short side plates are snap-fitted together, and the long side plates, short side plates and frame base plate are snap-fitted together. The frame base plate is made of high-strength thermoplastic plastic and is molded in one piece. The bottom of the frame base plate is designed with anti-slip grooves.
[0006] In the aforementioned folding turnover box, the long side plate and the short side plate are interlocked to form a rectangular frame by square locking posts on both sides of the long side plate and square locking slots on both sides of the short side plate.
[0007] In the aforementioned folding turnover box, the frame base plate is formed by thermoplastic molding to create slots and / or snap-fits for connecting with the long side plate and the short side plate.
[0008] Compared with the prior art, the present invention has the following advantages: the folding turnover box provided by the present invention can be used to store solid or semi-liquid items, is stably loaded, and is easy to fold and carry; since the frame base plate is made of high-strength thermoplastic plastic in one piece, it has good overall strength and connection strength, which greatly enhances the service life of the turnover box. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the folding turnover box structure of this utility model;
[0010] Figure 2 This is a schematic diagram of the bottom structure of the folding turnover box of this utility model after assembly. Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0012] Figure 1 This is a schematic diagram of the folding turnover box structure of this utility model; Figure 2 This is a schematic diagram of the bottom structure of the folding turnover box of this utility model after assembly.
[0013] Please see Figure 1 and Figure 2 The folding turnover box provided by this utility model includes a side frame and a frame base plate. The side frame is spliced together by a pair of parallel long side plates 1 and 3 and a pair of parallel short side plates 2 and 4. The long side plates 1 and 3 and the short side plates 2 and 4 are snap-fitted together, and the long side plates 1 and 3, the short side plates 2 and 4 and the frame base plate 5 are snap-fitted together. The frame base plate 3 is made of high-strength thermoplastic plastic and is designed with anti-slip grooves at the bottom.
[0014] In a preferred embodiment, the folding turnover box provided by this utility model has long side plates 1 and 3 and short side plates 2 and 4 that are interlocked by square locking posts on both sides of the long side plates and square locking slots on both sides of the short side plates to form a rectangular frame with dimensions of 6040x300. The frame base plate 3 is formed by thermoplastic molding to form locking slots and / or snap-fit openings for interlocking with the long side plates 1 and 3 and the short side plates 2 and 4.
[0015] The folding turnover box provided by this utility model can be used to store solid or semi-liquid items. It is stable and easy to fold and carry. Since the frame base plate is made of high-strength thermoplastic plastic in one piece, it has good overall strength and connection strength, which greatly enhances the service life of the turnover box.
[0016] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
