[0003] The utility model aims to provide a foldable turnover frame, which can avoid the problem that impurities are stuck in the splicing structure of the main and auxiliary side plates and are difficult to be discharged, thereby interfering with the buckling action of the main and auxiliary side plates.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a foldable turnover frame, including a bottom plate, a pair of main side plates and a pair of auxiliary side plates, the lower edges of the main side plates and the auxiliary side plates are hinged to the bottom plate respectively, and are characterized in that: the main side plate is formed with one or more positioning blocks 1 at its edge, and a plurality of the positioning blocks 1 are arranged at intervals and gaps are formed between adjacent positioning blocks 1; the auxiliary side plate is formed with positioning blocks 2 and filling blocks at its edge, the positioning block 1 is opposite to the positioning block 2 inside and outside, and the filling block corresponds to the gap inside and outside, and after the main side plate and the auxiliary side plate are supported in place relative to the bottom plate, the positioning block 1 and the positioning block 2 respectively have mutually matching snap-fitting structures on the mating surfaces, and the filling block just fits into the gap.

[0005] Preferably, the uppermost positioning block 1 forms a gap with the upper edge of the main side plate, and the lowermost positioning block 1 forms a gap with the lower edge of the main side plate.

[0006] Preferably, the first positioning block is formed on the extension surface of the main side panel to the secondary side panel, and the second positioning block and the filling block are formed on the extension surface of the plane where the secondary side panel is located, so as to match the folding mode of the secondary side panel inside and the main side panel outside.

[0007] Preferably, the thickness of the positioning block 1 and the positioning block 2 are respectively smaller than the thickness of the filling block, and the superimposed thickness of the positioning block 1 and the positioning block 2 after being buckled into place is equal to the thickness of the filling block, so that after the main and auxiliary side panels are buckled, a flat buckling surface is formed at the buckling position.

[0008] Preferably, the first positioning block forms a positioning hole on its mating surface, and the second positioning block forms a positioning shaft on its mating surface, and the positioning shaft is opposite to the inside and outside of the positioning hole, and when the first positioning block and the second positioning block are engaged with each other, the positioning shaft is correspondingly inserted into the positioning hole. This not only achieves accurate positioning, but also helps to improve the combination strength of the main and auxiliary side panels.

[0009] Preferably, the edge of the secondary side plate forms a support plate, and the second positioning block and the filling block are formed on the inner side of the support plate, so that the buckling structure is isolated from the contents in the frame, and the edge structure is prevented from scratching the items in the frame.

[0010] Compared with the prior art, the advantages of the utility model are: by designing the snap-fit ​​structure of the edge of the main side panel into a structure such as a positioning block and a gap, the gap is open inside and outside, and even if impurities are temporarily stuck in the gap, the impurities will be pushed out when the gap and the filling block are engaged, so as not to affect the normal engagement of the main and secondary side panels. The cooperation between the gap and the filling block overcomes the problem of foreign matter being stuck in the snap-fit ​​cavity and not being able to be discharged.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings. The embodiments are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention. The text description in this embodiment corresponds to the accompanying drawings, and the description of the orientation is also based on the description of the accompanying drawings, and should not be understood as limiting the scope of protection of the present invention.

[0022] like Figure 1 As shown, a foldable turnover frame in this embodiment has a square frame structure as a whole, including a base plate 1, a pair of main side plates 2 and a pair of auxiliary side plates 3. The lower edges of the two main side plates 2 are hinged to the two long sides of the base plate 1 respectively through the matching structure of the shaft with a torsion spring and the shaft hole, and the lower edges of the two auxiliary side plates 3 are hinged to the two short sides of the base plate 1 respectively through the matching structure of the shaft and the shaft hole. The main and auxiliary side plates can stand up and tilt inward relative to the base plate.

[0023] The edge where the main side panel 2 is spliced ​​with the auxiliary side panel 3 is formed with two positioning blocks 1 4, the two positioning blocks 1 extend toward the auxiliary side panel 3, the two positioning blocks 1 4 are arranged at intervals to form a gap 5, and the two positioning blocks 1 and the upper and lower edges of the main side panel also have gaps 5 respectively. A positioning hole 8 is opened on the inner side of each positioning block 1.

[0024] The secondary side panel 3 is formed with two positioning blocks 2 6 and three filling blocks 7 at the edge where it is spliced ​​with the primary side panel 2. The two positioning blocks 2 6 are opposite to the positioning block 1 4 inside and outside. A positioning shaft 9 is provided on the outer side surface of the positioning block 2 6. The positioning shaft 9 is opposite to the positioning hole 8 inside and outside. The three filling blocks 7 correspond to the three gaps 5 at the edge of the primary side panel 2 inside and outside and have the same size.

[0025] After the main side plate 2 and the auxiliary side plate 3 are erected in place relative to the bottom plate 1, the positioning block 1 4 and the positioning block 2 6 are respectively aligned and pressed against each other, the positioning shaft 9 is correspondingly inserted into the positioning hole 8, and the filling block 7 is just inserted into the gap 5. The superimposed thickness of the positioning block 1 4 and the positioning block 2 6 is equal to the thickness of the filling block 7, so that a relatively flat splicing surface is formed after the main side plate 2 and the auxiliary side plate 3 are spliced.

[0026] In this embodiment, a support plate 10 is formed at one side edge of the secondary side plate 3, and the positioning block 6 and the filling block 7 on this side are formed on the inner side surface of the support plate 10. The support plate 10 can isolate the splicing structure from the material in the frame to prevent impurities from getting stuck in the matching gap between the filling block 7 and the gap 5. The support plate 10 is only an optional design structure of the turnover frame in this case. The support plate 10 is mainly set at the edge of the secondary side plate, and is not used for the edges of the main and secondary side plates at the same time.

[0027] The foldable turnover frame structure is ingenious, convenient for mold forming and manufacturing, and avoids the problem of debris getting stuck in the splicing structure of the main and auxiliary side panels, thereby affecting the smooth splicing of the two.

[0028] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
