[0027] See also Figure 1 A spare folding bracket comprises a bottom plate 1, both ends of the bottom plate 1 are hinged with end walls 2, four corners of the bottom plate 1 are provided with first corner pieces 3, two corners of the upper ends of the end walls 2 are provided with second corner pieces 4, and the bottom plate 1 is a grid-like structure.

[0028] When in use, the spare parts of the engineering vehicle are uniformly placed on the base plate 1, and the end walls 2 are erected at both ends of the base plate 1, which is convenient for the management of spare parts, and multiple spare parts folding brackets can be stacked and placed in the vertical direction. The two upper and lower adjacent spare parts folding brackets are fixed by twist locks to lock the first corner pieces 3 at the four corners of the base plate 1 in the upper spare parts folding bracket and the second corner pieces 4 at the two upper corners of the end wall 2 in the lower spare parts folding bracket. Each end wall 2 is fixed to one end of the base plate 1 in the upper spare parts folding bracket by two twist locks, thereby reducing the footprint and ensuring maximum utilization of the space; since the base plate 1 is a grid-like structure, the material of the base plate 1 can be saved, thereby reducing the cost of the spare parts folding bracket; in addition, since the end wall 2 is hinged to the base plate 1, when the spare parts folding bracket is idle, the end wall 2 can be folded toward the base plate 1 and placed on the base plate 1 to save the space occupied by the idle spare parts folding bracket, and the folded spare parts folding bracket can be stacked and placed in the vertical direction, which can further save space. The first corner fitting 3 and the second corner fitting 4 are both container corner fittings, also known as box corners or hanging corners, and the two corner fittings can be locked with a twist lock.

[0029] The bottom plate 1 includes a frame 11, a plurality of longitudinal beams 12 arranged in parallel, and a plurality of transverse beams 13 arranged in parallel. The plurality of longitudinal beams 12 are arranged longitudinally in the frame 11, and the plurality of transverse beams 13 are arranged transversely in the frame 11. Each transverse beam 13 passes through the plurality of longitudinal beams 12. By arranging the plurality of longitudinal beams 12 and the plurality of transverse beams 13 in the frame 11, a grid-shaped bottom plate 1 is formed, and the material used for the bottom plate 1 is reduced. The longitudinal beams 12 are I-beams, and the transverse beams 13 are channel steels. I-beams and channel steels are common materials and are easily available. There is no need to open a mold to manufacture the longitudinal beams 12, and the cost is lower.

[0030] The end wall 2 includes two columns 21 and a top beam 22 connecting the upper ends of the two columns 21. The second corner piece 4 is located at the upper ends of the columns 21. The lower ends of the two columns 21 are respectively hinged to the two sides of the same end of the bottom plate 1. In fact, a connecting rod (not shown) can be added between the two columns 21 to enhance the strength of the end wall 2.

[0031] Preferably, see Figures 1 to 3 Two first grooves 113 are provided at the top of the longitudinal edge 111 of the frame 11, and two second grooves 121 are provided at the top of each longitudinal beam 12 corresponding to the position of the first groove 113. When the end wall 2 is folded toward the bottom plate 1, the top beam 22 is placed in the first groove 113 and the second groove 121. The two first grooves 113 are symmetrically arranged on the longitudinal edges 111 of the frame 11, and can respectively accommodate the top beams 22 of the two folded end walls 2; the two second grooves 121 are also symmetrically arranged on the longitudinal beams 12, and can respectively accommodate the top beams 22 of the two folded end walls 2; when the end walls 2 are folded toward the bottom plate 1, the top beam 22 of one of the end walls 2 is hidden in the first grooves 113 on the same side of the two longitudinal edges 111 and in the second grooves 121 on the same side of the multiple longitudinal beams 12, and the top beam 22 of the other end wall 2 is hidden in the first grooves 113 on the other side of the two longitudinal edges 111 and in the second grooves 121 on the other side of the multiple longitudinal beams 12, so that the surface of the folded spare parts folding bracket is smoother and occupies less space.

[0032] For further information, see Figure 1 and Figure 2 An extension plate 5 is provided on both sides of the bottom plate 1, and two protrusions 51 are provided on the extension plate 5. The positions of the two protrusions 51 correspond to the two first grooves 113 respectively. When the end wall 2 is folded toward the bottom plate 1, the second corner piece 4 is placed on the protrusion 51, which can avoid the end wall 2 shaking due to the suspension between the second corner piece 4 and the extension plate 5 after folding, thereby improving stability.

[0033] Preferably, see Figure 2 and Figure 3A locking assembly 8 is provided in the middle of both sides of the frame 11, and the locking assembly 8 includes a mounting bracket 81, a latch 82, a spring 83 and a handle 84. The mounting bracket 81 is installed on the side of the frame 11, and the mounting bracket 81 has an empty slot 811. The latch 82 is telescopically arranged on the mounting bracket 81 and longitudinally penetrates the mounting bracket 81. The spring 83 is sleeved in the middle of the latch 82 and is located in the empty slot 811. Both ends of the spring 83 are in contact with the slot wall of the empty slot 811, and the handle 84 is arranged at the end of the latch 82 away from the end wall 2. When the end wall 2 needs to be folded, the latch 82 is pulled in the direction away from the end wall 2 by the handle 84, so that the end of the latch 82 close to the end wall 2 is retracted into the empty slot 811 until the end wall 2 is folded on the bottom plate 1. At this time, the spring 83 is compressed, and then the handle 84 is released. Under the rebound action of the spring 83, the end of the latch 82 close to the end wall 2 extends out of the empty slot 811 and passes through the mounting bracket 81 and then extends into the top hole of the second corner piece 4, so that the latch 82 locks the end wall 2, prevents the end wall 2 from shaking and limits the flipping of the end wall 2.

[0034] Preferably, see Figure 1 and Figure 2 The spare part folding bracket further includes two square tubes 6, which extend horizontally through the frame 11 and are located in the middle of the frame 11. The inner cavities of the two square tubes 6 extending through the frame 11 can be used as insertion cavities for forklift forks. When the forklift forks are inserted into the inner cavities of the square tubes 6, the spare part folding bracket can be transported by the forklift.

[0035] Preferably, see Figure 1 and Figure 4 A base 23 is provided at the lower end of the column 21, and the base 23 is hinged to the bottom plate 1, so that the end wall 2 can be flipped. Limiting components 7 are provided on both sides of the end surface of the bottom plate 1. The limiting components 7 are used to fix the vertically placed end wall 2. The limiting components 7 include a vertical plate 71 and a limiting bar 72. The vertical plate 71 is arranged on the end surface of the bottom plate 1, and the limiting bar 72 is telescopically arranged on the vertical plate 71. A through hole 231 is provided at a position corresponding to the limiting bar 72 on the base 23. The limiting bar 72 can extend into or leave the through hole 231 when it is telescopic. When the end wall 2 is placed vertically, the limiting bar 72 is pushed to make the limiting bar 72 extend into the through hole 231 to fix the end wall 2; when the end wall 2 needs to be folded, the limiting bar 72 is first pulled out to make the limiting bar 72 leave the through hole 231, and the flipping restriction of the end wall 2 by the limiting bar 72 is released, so that the end wall 2 can be flipped and folded. In order to ensure that the rear end wall 2 cannot rotate after the limiting strip 72 extends into the through hole 231, the through hole 231 cannot be circular, but can be rectangular, triangular, pentagonal, hexagonal, special-shaped, heart-shaped, star-shaped, etc.

[0036] Preferably, the limiting assembly 7 further includes a handle 73, which is disposed at one end of the limiting strip 72 away from the base 23. The setting of the handle 73 facilitates the dragging of the limiting strip 72, and the operator can push or pull out the limiting strip 72 through the handle 73, so that the limiting strip 72 extends into or leaves the through hole 231.

[0037] Preferably, the limiting assembly 7 also includes a clamping block 74 located above the limiting strip 72. The clamping block 74 is hinged to the vertical plate 71 through a rotating shaft 75, so that the clamping block 74 can rotate. The limiting strip 72 is provided with a first clamping slot 721 and a second clamping slot 722. The clamping block 74 is rotated so that the clamping block 74 is clamped in the first clamping slot 721 or the second clamping slot 722 to limit the extension and retraction of the limiting strip 72. When the end wall 2 is placed vertically, the clamping block 74 is rotated so that the clamping block 74 leaves the second clamping slot 722, and then the limiting strip 72 is pushed so that the limiting strip 72 extends into the through hole 231 and the clamping block 74 is aligned with the first clamping slot 721. Then, the clamping block 74 is rotated in the opposite direction so that the clamping block 74 is clamped in the first clamping slot 721. At this time, the limiting strip 72 is limited by the clamping block 74 and cannot be extended or retracted. Moreover, the limiting strip 72 limits the flipping of the end wall 2 so that the end wall 2 can be kept placed vertically. When folding is required, When folding the end wall 2, first rotate the block 74 to make the block 74 leave the first slot 721, and then pull out the limit strip 72 until the block 74 is aligned with the second slot 722. At this time, the limit strip 72 leaves the through hole 231, and the limit strip 72 is released from the flipping restriction of the end wall 2, so that the end wall 2 can be flipped and folded, and then the block 74 is rotated in the opposite direction to make the block 74 engage in the second slot 722, thereby limiting the extension and retraction of the limit strip 72 and preventing the limit strip 72 from moving freely during transportation.
