[0009] Further, a jack for inserting the plug rod is formed in the middle of the clamping plug, and a friction gasket in contact with the plug rod is fixedly connected to the inner side wall of the jack.

[0010] Further, the outer diameter of the clamping plug gradually decreases from top to bottom, so that the outer side wall of the clamping plug is inserted into the connecting sleeve in a flared shape.

[0011] Further, a bevel angle fitting the outer side wall of the clamping plug is formed at the opening of the inner side wall of the connecting sleeve, and deformation grooves for being compressed and deformed are equidistantly spaced on the outer side wall of the clamping plug.

[0012] Further, the length of the first side wall plate plus the widths of the two second side wall plates on both sides is equal to the width of the bottom plate, so that when the first side wall plate and the second side wall plates are perpendicular to the bottom plate, they form a complete rectangular frame.

[0013] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0014] 1. For the collapsible wooden pallet with side walls, by arranging the support assembly, the depth of the plug rod inserted into the connecting sleeve can be directly adjusted to change the length of the support assembly, so that the inclination angle of the first side wall plate and the second side wall plate can be adjusted more conveniently, the opening preparation time of the first side wall plate and the second side wall plate of the wooden pallet can be greatly reduced, and the practicability of the wooden pallet can be improved.

Detailed implementation manners

[0023] The following further elaborates on the present utility model with reference to the accompanying drawings.

[0024] Embodiment:

[0025] Refer to Figure 1 - Figure 5 A wooden pallet with foldable side walls disclosed by the present utility model includes a bottom plate 1. A first side wall plate 2 is hinged to the left and right edges of the bottom plate 1 along the long side direction, and a second side wall plate 3 is hinged to the front and back edges of the bottom plate 1 along the short side direction. Connecting seats 4 are provided in the middle of the outer side walls of the first side wall plate 2 and the second side wall plate 3 and on the outer side walls around the bottom plate 1. A support assembly 5 is provided between the corresponding two connecting seats 4.

[0026] In this embodiment, when the wooden pallet is carrying goods, the goods located at the edge of the wooden pallet will shake when the wooden pallet moves and bumps, so that the goods at the edge are likely to fall, affecting the transfer of goods.

[0027] Therefore, it can be observed that Figure 1 A first side wall plate 2 is provided on the left and right sides of the bottom plate 1 along the long side direction, and then a second side wall plate 3 is provided on the front and back sides of the bottom plate 1 along the short side direction. The first side wall plate 2 and the second side wall plate 3 enclose the top of the bottom plate 1 to provide support for the goods on the top of the bottom plate 1, preventing them from falling and making the transportation of goods more stable, thereby improving the practicality of the wooden pallet.

[0028] The provided support component 5 can change the unfolding angles of the first side wall plate 2 and the second side wall plate 3 of the wooden pallet, increasing the amount of goods that can be placed on the top of the wooden pallet, further enhancing the load-bearing capacity of the goods, and thus further improving the practicality of the wooden pallet.

[0029] When the volume of the goods is large and the placement of the goods is relatively stable and not easily affected by bumps and falls, the wooden pallet can be made as Figure 3 shown, using the support component 5 to fully unfold the first side wall plate 2 and the second side wall plate 3, which can be used to increase the loading area of the wooden pallet, thereby increasing the loading capacity of the wooden pallet; and when the volume of the goods is large and the placement stability is also relatively poor, the first side wall plate 2 and the second side wall plate 3 of the wooden pallet are made as Figure 2 shown, unfolding slightly, increasing the loading capacity of the wooden pallet while ensuring that the goods do not fall, and improving the applicable range of the wooden pallet.

[0030] In a further preferred embodiment of the present utility model, as Figure 4 shown, the support component 5 includes a plug rod 51, a connecting sleeve 52, and a clamping plug 53. The connecting sleeve 52 and the plug rod 51 are respectively hinged to the connecting seat 4 of the bottom plate 1 and the first side wall plate 2. The plug rod 51 is inserted into the connecting sleeve 52, and a clamping plug 53 for clamping the plug rod 51 is provided at the opening of the connecting sleeve 52.

[0031] In this embodiment, by providing the plug rod 51 and the connecting sleeve 52, the length of the support component 5 can be changed by changing the depth of the plug rod 51 inserted into the connecting sleeve 52, thereby changing the unfolding amplitude of the first side wall plate 2 and the second side wall plate 3, and achieving the effect of adjusting the folding amplitude of the side walls of the wooden pallet.

[0032] However, since the plug rod 51 and the connecting sleeve 52 can slide relative to each other, the bearing capacity of the first side wall plate 2 and the second side wall plate 3 of the wooden pallet is not strong. When loading goods in the wooden pallet, the first side wall plate 2 and the second side wall plate 3 are pushed open by the goods, causing the goods to fall, affecting the use of the wooden pallet. Therefore, it can be observed that Figure 4 a clamping plug 53 is provided between the plug rod 51 and the connecting sleeve 52. When it is necessary to fix the plug rod 51 and the connecting sleeve 52, the clamping plug 53 is inserted between the plug rod 51 and the connecting sleeve 52 to reduce the movable gap between the plug rod 51 and the connecting sleeve 52, making the plug rod 51 and the connecting sleeve 52 relatively fixed, thereby avoiding the first side wall plate 2 and the second side wall plate 3 from being squeezed open by the goods and improving the use stability of the wooden pallet.

[0033] In a further preferred embodiment of the present utility model, as Figure 4 and Figure 5As shown, a jack 6 for inserting the plug rod 51 is provided in the middle of the clamping insert block 53, and a friction gasket 7 in contact with the plug rod 51 is fixedly connected to the inner side wall of the jack 6.

[0034] In this embodiment, by providing the jack 6 on the clamping insert block 53, the clamping insert block 53 can be sleeved outside the plug rod 51. When the positions of the plug rod 51 and the connecting sleeve 52 are fixed, the clamping insert block 53 can be directly inserted into the gap between the plug rod 51 and the connecting sleeve 52, making the fixing method of the support assembly 5 simpler.

[0035] Since when the clamping insert block 53 is inserted into the gap between the plug rod 51 and the connecting sleeve 52, the inner side wall of the jack 6 will fit with the plug rod 51 under extrusion, using the pressure to increase the friction force to prevent the plug rod 51 from moving. Therefore, a friction gasket 7 is provided on the inner side wall of the jack 6, which can further increase the friction coefficient and enhance the friction force, making the fixing of the plug rod 51 more stable, and thus making the support of the support assembly 5 more stable.

[0036] In a further preferred embodiment of the present utility model, as Figure 4 and Figure 5 shown, the outer diameter of the outer side wall of the clamping insert block 53 gradually decreases from top to bottom, so that the outer side wall of the clamping insert block 53 is inserted into the connecting sleeve 52 in a flared shape.

[0037] In this embodiment, when the goods squeeze the first side wall plate 2 and the second side wall plate 3, the first side wall plate 2 and the second side wall plate 3 will be opened, so that the distance between the connecting seats 4 of the first side wall plate 2 and the second side wall plate 3 and the connecting seats 4 opposite to the bottom plate 1 decreases, and the plug rod 51 is pressed into the connecting sleeve 52.

[0038] Therefore, by observing Figure 4 and Figure 5 it can be found that the outer diameter of the outer side wall of the clamping insert block 53 gradually decreases from top to bottom to form a flared shape. At this time, when the clamping insert block 53 moves downward under the driving of the friction force of the plug rod 51, it will drive the clamping insert block 53 to move downward, so that the clamping insert block 53 is squeezed by the opening of the connecting sleeve 52, reducing the inner diameter of the jack 6 of the clamping insert block 53, thereby applying a stronger pressure on the plug rod 51 by the jack 6, further increasing the friction force between the clamping insert block 53 and the plug rod 51, and preventing the plug rod 51 from moving downward. Therefore, when the wooden pallet is loaded with goods, the greater the pressure on the support assembly 5, the better the support stability of the support assembly 5, which can effectively improve the support effect of the support assembly 5.

[0039] In a further preferred embodiment of the present utility model, as Figure 4 and Figure 5As shown, at the opening of the inner side wall of the connecting sleeve 52, an inclined angle 8 that fits the outer side wall of the clamping insert block 53 is provided, and deformation grooves 9 for undergoing pressure deformation are equidistantly spaced on the outer side wall of the clamping insert block 53.

[0040] In this embodiment, by providing an inclined angle 8 at the opening of the connecting sleeve 52 that fits the outer wall of the clamping insert block 53, the clamping insert block 53 can be inserted into the connecting sleeve 52 better, further reducing the difficulty of using the support assembly 5.

[0041] And by providing deformation grooves 9 for deformation on the outer side wall of the clamping insert block 53, the clamping insert block 53 can be more easily deformed when being pushed downward by the inserting rod 51, making the inner diameter of the jacking hole 6 more easily reduced under pressure, so that the downward pressure response of the clamping insert block 53 to the inserting rod 51 is more sensitive, improving the support effect of the support assembly 5.

[0042] In a further preferred embodiment of the present utility model, as Figure 1 shown, the length of the first side wall plate 2 plus the widths of the two second side wall plates 3 on both sides is equal to the width of the bottom plate 1, so that when the first side wall plate 2 and the second side wall plates 3 are perpendicular to the bottom plate 1, they form a complete rectangular frame.

[0043] In this embodiment, due to the arrangement of the first side wall plate 2 and the second side wall plates 3, when they are fully supported, they will interfere with each other, resulting in a gap at the junction of the first side wall plate 2 and the second side wall plates 3. When transporting some goods with good fluidity and small volume, the goods are likely to leak from the gap, affecting the transportation of the goods.

[0044] Therefore, it can be observed Figure 1 that making the length of the first side wall plate 2 less than the width of the bottom plate 1 and making the length of the first side wall plate 2 plus the widths of the two second side wall plates 3 on both sides equal to the width of the bottom plate 1 can form a rectangular frame when the first side wall plate 2 and the second side wall plates 3 are fully propped up, effectively reducing the generation of gaps, making the goods transportation effect better, and further improving the practicality of the wooden pallet.

[0045] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
