DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 5 The utility model discloses a retractable wooden pallet, comprising a main pallet 1 and a sub-pallet 2, wherein the outer side wall of the main pallet 1 is provided with a plurality of guide parts 3 formed by projections at equal intervals in the horizontal direction, and the outer side wall of the sub-pallet 2 is provided with a slot 4 for inserting the guide part 3, so that when the guide part 3 is inserted into the slot 4, the main pallet 1 and the sub-pallet 2 form a complete pallet, and movable wheels 5 for providing support are provided at the bottom edges of the main pallet 1 and the sub-pallet 2, and a reinforcing support assembly 6 is provided between the main pallet 1 and the sub-pallet 2.

[0026] In this embodiment, since the wooden pallet cannot change its shape freely after production, the wooden pallet cannot freely extend the loading surface when transporting larger volume goods. The larger volume goods can only be transported by unpacking the goods into small pieces or splicing multiple wooden pallets together, which affects the practicality of the wooden pallet.

[0027] So observe Figure 1 - Figure 3It can be found that the complete wooden pallet is divided into a main pallet 1 and a sub-pallet 2, and a guide portion 3 is provided on the outer wall of the main pallet 1, and a slot 4 for inserting the guide portion 3 is provided on the outer wall of the sub-pallet 2, so that the main pallet 1 and the sub-pallet 2 can have space for telescopic deformation, so that when the wooden pallet is transporting some larger goods, the cargo surface can be increased by stretching, so that the wooden pallet can transport larger volumes of goods, which can effectively improve the practicality of the wooden pallet.

[0028] When the wooden pallet is stretched, the contact surface of the middle connection will inevitably decrease, which will weaken the compressive performance of the wooden pallet when loaded. When the cargo is heavy, the contact surface of the middle connection will bear a greater load, causing the wooden pallet to be broken and damaged. Figure 3 It can be found that a reinforcing support assembly 6 is provided at the bottom of the wooden pallet, which can provide support to the middle of the wooden pallet when it is stretched, thereby improving the compressive resistance of the weak points of the wooden pallet and avoiding the middle part of the wooden pallet from directly bearing pressure, thereby effectively increasing the compressive resistance and service life of the wooden pallet and further improving the practicality of the wooden pallet.

[0029] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the reinforcing support assembly 6 includes load-bearing wheels 61, a crossbeam 62 and a positioning assembly 63. The crossbeam 62 is arranged between the main pallet 1 and the sub-pallet 2, and is connected to the main pallet 1 and the sub-pallet 2 through the positioning assembly 63. The two ends of the crossbeam 62 are fixedly connected with load-bearing wheels 61.

[0030] In this embodiment, when the wooden pallet is stretched, the relative contact surface of its active parts will be reduced, resulting in poor compression resistance and affecting the loading capacity of the wooden pallet. Figure 3 It can be found that by providing the load-bearing wheels 61 and the crossbeam 62, support can be provided for the bottom of the wooden pallet, thereby preventing the middle movable part of the wooden pallet from being broken due to excessive pressure when the wooden pallet is stretched.

[0031] Since the main pallet 1 and the sub-pallet 2 can be separated, the main pallet 1 and the sub-pallet 2 will be compressed and closed when they are unfolded to load goods, or the main pallet 1 and the sub-pallet 2 will be compressed and unfolded when they are closed to load goods, which will affect the stability of the goods and thus affect the use of the wooden pallet. Therefore, a positioning component 63 is provided in the beam 62. The positioning component 63 is used to control the extension of the main pallet 1 and the sub-pallet 2, so that the wooden pallet can be loaded more stably and the practicality of the wooden pallet can be improved.

[0032] In a further preferred embodiment of the present invention, Figure 4As shown, at least two groups of through holes 7 are formed on the outer side wall of the crossbeam 62 , and each group of through holes 7 is provided with two through holes 7 at intervals and connected to the positioning components 63 , and the two positioning components 63 are respectively connected to the main pallet 1 and the auxiliary pallet 2 .

[0033] In this embodiment, by providing at least two groups of through holes 7 on the outer wall of the crossbeam 62, a plurality of positioning assemblies 63 can be installed on the crossbeam 62. By providing each group of through holes 7 with two through holes 7 spaced apart, and by providing that the positioning assemblies 63 connected in the two through holes 7 are respectively connected to the main pallet 1 and the sub-pallet 2, the wooden pallet can be restricted by the positioning assemblies 63 when being extended, thereby preventing the main pallet 1 and the sub-pallet 2 from being separated too far and causing the wooden pallet to disintegrate.

[0034] In a further preferred embodiment of the present invention, Figure 5 As shown, the positioning assembly 63 is composed of a positioning block 631, a positioning rod 632 and a ball 633, wherein the positioning rod 632 is slidably connected to the through hole 7, and the end of the positioning rod 632 close to the main tray 1 is fixedly connected to the main tray 1 through the positioning block 631, and a circular groove 8 is opened in the through hole 7 and a ball 633 is provided, and the ball 633 is connected to the circular groove 8 through a supporting spring 9, and the outer wall of the positioning rod 632 is evenly spaced with slots 10 for clamping the ball 633.

[0035] In this embodiment, by setting the positioning rod 632 and the positioning block 631, the main pallet 1 and the sub-pallet 2 can remain connected to the crossbeam 62 when they are relatively far apart, and a slot 10 is opened on the outer wall of the positioning rod 632, and a circular slot 8 is opened in the through hole 7, and a ball 633 is connected through a support spring 9, so that when the positioning rod 632 moves, the ball 633 will be pressed into the circular groove 8 until the ball 633 contacts the next slot 10 and is pushed out by the support spring 9 and re-engaged in the slot 10. When the positioning rod 632 slides in the through hole 7, the extension range of the wooden pallet can be positioned by the engagement of the ball 633 with different slots 10, making the use of the wooden pallet more convenient.

[0036] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, one end of the positioning rod 632 away from the positioning block 631 extends out of the through hole 7 and is fixedly connected to a pressing block 11 . A compression spring 12 is provided between the pressing block 11 and the crossbeam 62 .

[0037] In the present embodiment, since the main pallet 1 and the sub-pallet 2 will be relatively far apart when the wooden pallet is extended, the crossbeam 62 can only be connected to one of the main pallet 1 or the sub-pallet 2. However, this will also cause the crossbeam 62 to be carried and move along with the main pallet 1 and the sub-pallet 2 when they are relatively far apart, causing the support point of the crossbeam 62 and the load-bearing wheel 61 on the wooden pallet to shift, which will cause one of the pressure arms of the main pallet 1 and the sub-pallet 2 to be shorter than the other, resulting in one of them bearing greater pressure and the other bearing less pressure. Therefore, the aging degree of the main pallet 1 and the sub-pallet 2 will be different, affecting the use of the wooden pallet.

[0038] So observe Figure 3 and Figure 4 It can be found that a pressing block 11 is connected to the end of the positioning rod 632 away from the positioning block 631, and a compression spring 12 is arranged between the pressing block 11 and the cross beam 62, so that when the main tray 1 and the auxiliary tray 2 are away from each other, the positioning rod 632 pulls the pressing block 11 to squeeze the compression spring 12, so that the compression spring 12 pushes the cross beam 62 to move with the corresponding positioning rod 632. Figure 4 It can be seen that the two adjacent groups of positioning components 63 are arranged oppositely, so that the pressure applied by the compression springs 12 on both sides of the beam 62 is the same, so that the beam 62 is always between the positioning blocks 631 on both sides, thereby preventing the beam 62 from moving with one of the pallets, and making the beam 62 always provide support for the middle of the bottom of the wooden pallet, so that the main pallet 1 and the auxiliary pallet 2 are subjected to the same load when loading goods, so that the service life of the two pallets is the same, avoiding the situation where one of them is scrapped while the other can still be used.

[0039] In a further preferred embodiment of the present invention, Figure 2 As shown, an extension portion 13 is formed on the outer wall of the guide portion 3 , and a track groove 14 for connecting the extension portion 13 is formed on the inner wall of the slot 4 .

[0040] In this embodiment, since the main pallet 1 and the sub-pallet 2 are connected to the crossbeam 62 only through the positioning blocks 631 and the positioning rods 632, when the transportation road surface is uneven, the pallet on the suspended side is only under pressure through the corresponding positioning blocks 631, causing the main pallet 1 and the sub-pallet 2 to be easily damaged when transporting on uneven roads.

[0041] So observe Figure 2 It can be found that an extension portion 13 is provided on the outer wall of the guide portion 3, and a track groove 14 for connecting the extension portion 13 is opened in the slot 4, so that the load is transferred between the main pallet 1 and the sub-pallet 2 through the extension portion 13 and the track groove 14, which can reduce the pressure on the positioning block 631 and effectively improve the service life of the wooden pallet.

[0042] In a further preferred embodiment of the present invention, Figure 1 As shown, through slots 15 are provided on the tops of the main tray 1 and the sub-tray 2 , and the two through slots 15 are located at the edges of the main tray 1 and the sub-tray 2 on opposite sides, respectively.

[0043] In this embodiment, by opening a through slot 15 on the outer side walls of the main pallet 1 and the sub-pallet 2, when the wooden pallet needs to be stretched, the main pallet 1 and the sub-pallet 2 can be separated by pulling the corresponding through slot 15, making it easier to exert force when stretching the wooden pallet, further reducing the difficulty of using the wooden pallet.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
