DETAILED DESCRIPTION
[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0023] Example:
[0024] Reference Figure 1 - Figure 5 The utility model discloses an expandable wooden pallet, comprising a pallet body 1, wherein movable wheels 2 are installed at the four corners of the bottom of the pallet body 1, a first expansion component 3 is arranged at the front and rear edges of the pallet body 1 along the width direction, a second expansion component 4 is arranged at the left and right edges of the pallet body 1 along the length direction, and a through hole 5 for carrying is opened at one side edge of the pallet body 1.
[0025] In this embodiment, by providing moving wheels 2 at the four corners of the bottom of the pallet body 1, some simple moving operations can be performed when goods are placed on the top of the pallet body 1, so as to facilitate fine-tuning the position of the pallet body 1 during use.
[0026] However, since the pallet body 1 is a customized product and the wooden pallet has been finalized during production and cannot change its shape during subsequent use, the cargo capacity that can be held during use cannot exceed the upper limit of the pallet body 1. As a result, when there is a large amount of cargo, multiple wooden pallets need to be used to hold it in groups, and multiple wooden pallets need to be transported separately during subsequent transportation, resulting in low efficiency in cargo transportation and affecting the practicability of the pallet body 1.
[0027] So observe Figure 1 It can be found that the first expansion component 3 and the second expansion component 4 are arranged on the outer peripheral side of the tray body 1. Figure 2 When the capacity of a pallet body 1 for holding goods is insufficient, multiple pallet bodies 1 can be combined to form a larger mobile wooden pallet, so that the wooden pallet can be freely expanded according to usage requirements, which can effectively improve the practicality of the wooden pallet and the flexibility of use of the wooden pallet.
[0028] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the first expansion component 3 is composed of a first positioning block 31 and a first hook 32. The first positioning block 31 is provided in two groups and is symmetrically arranged on the same side of the tray body 1. The side of the tray body 1 away from the first positioning block 31 is provided with a first positioning slot 6 that fits with the first positioning block 31. The bottom of the first positioning slot 6 is connected to the first hook 32. The bottom of the first positioning block 31 is provided with a first slot 7 for inserting the first hook 32.
[0029] In this embodiment, since the first expansion component 3 is arranged on the long side of the tray body 1, in order to make more stress points when multiple tray bodies 1 are spliced and expanded, the tray bodies 1 are more stable after splicing. Figure 1 As shown, two groups of first positioning blocks 31 are symmetrically arranged on the long side of the tray body 1, and two groups of first positioning slots 6 that fit the first positioning blocks 31 are symmetrically opened on the other side of the tray body 1, so that the long side of the tray body 1 can be as shown. Figure 2 The way shown is put together, and then look at the Figure 1 It can be found that a first hook 32 is connected to the bottom of the first positioning slot 6, and a first slot 7 is provided on the first positioning insert block 31, so that two adjacent tray bodies 1 can be Figure 2 When put together in the manner shown, the first hook 32 is used to hook the first slot 7, so that the two pallet bodies 1 can be stably connected together, so that the wooden pallet can maintain a stable connection state after expansion, thereby improving the practicality of the wooden pallet.
[0030] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the second expansion component 4 is composed of a second positioning block 41 and a second hook 42, the second positioning block 41 is fixedly connected to the tray body 1, and a second positioning slot 8 that fits with the second positioning block 41 is provided on the side of the tray body 1 away from the second positioning block 41, and the bottom of the second positioning slot 8 is connected to the second hook 42, and the bottom of the second positioning block 41 is provided with a second slot 9 for inserting the second hook 42, and the width of the second hook 42 and the second positioning block 41 are both greater than the width of the first hook 32 and the first positioning block 31.
[0031] In this embodiment, since the width of the tray body 1 is shorter than the length of the long side, the width cannot be provided with the second positioning plug 41 in the same manner as the long side. Figure 1 It can be found that in order to make the force uniform and stable when two adjacent tray bodies 1 are connected, a second positioning block 41 is provided in the middle of the wide side of the tray body 1, and a second positioning slot 8 that fits with the second positioning block 41 is provided on the other wide side of the tray body 1, so that the wide sides of the two adjacent tray bodies 1 can be connected as shown in FIG. Figure 2 Stitch together as shown.
[0032] Then combine Figure 1 and Figure 2 It can be found that a second card slot 9 is provided on the second positioning plug block 41, and a second hook 42 arranged at the bottom of the second positioning slot 8 will clamp the corresponding second card slot 9 when the two tray bodies 1 are spliced together, making the splicing of the two adjacent tray bodies 1 more stable.
[0033] However, since the short sides cannot be provided with multiple second positioning blocks 41 like the long sides, in order to improve the stability of the wooden pallet after expansion, the widths of the second positioning blocks 41 and the second hooks 42 are made larger than the first positioning blocks 31 and the first hooks 32. The defect in quantity is compensated by increasing the contact surface, thereby effectively ensuring the connection stability of the wooden pallet after expansion.
[0034] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the bottom of each of the first positioning plug block 31 and the second positioning plug block 41 is provided with a guide surface 10 , and the top corners of the guide surface 10 are higher than the tops of the first hook 32 and the second hook 42 .
[0035] In this embodiment, when the wooden pallet is expanded, one of the pallet bodies 1 needs to be lifted up so that the first hook 32 can be inserted into the corresponding first slot 7. When the number of spliced wooden pallets is too large, the physical exertion of the personnel will be seriously increased, affecting the subsequent work efficiency.
[0036] So observe Figure 4 It can be found that a guide surface 10 is provided at the bottom of the first positioning plug 31, and the top corner of the guide surface 10 is higher than the top of the first hook 32, so that when two adjacent tray bodies 1 are spliced, the first hook 32 will preferentially contact the guide surface 10 of the first positioning plug 31, and the lateral pressure generated when the tray bodies 1 are close to each other is used to guide the first hook 32 to be pressed down through the guide surface 10, so that the first hook 32 is Figure 5 As shown, it is pressed to the bottom of the first positioning block 31. Finally, when the first positioning block 31 is fitted with the first positioning slot 6, the first hook 32 loses the extrusion and rebounds to reset and is inserted into the first slot 7, completing the splicing of the two pallet bodies 1. This can effectively reduce the difficulty of expanding the pallet body 1 and improve the splicing efficiency of the wooden pallet.
[0037] The second positioning block 41 and the second hook 42 are similar, and can effectively improve the splicing efficiency of the tray body 1 .
[0038] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the hook ends of the first hook 32 and the second hook 42 are processed with chamfers 11 that contact the guide surface 10 , and an elastic component 12 is provided between the handle ends of the first hook 32 and the second hook 42 and the tray body 1 .
[0039] In this embodiment, when the first positioning block 31 squeezes the first hook 32, the edges of the first hook 32 will scratch the guide surface 10, making the guide surface 10 rough, thereby increasing the subsequent splicing resistance and affecting the subsequent expansion of the wooden pallet.
[0040] So observe Figure 4 It can be found that chamfers 11 in contact with the guide surface 10 are provided at the corners of the first hook 32 , which can prevent the guide surface 10 from being scratched and increase the service life of the first expansion component 3 .
[0041] When the first hook 32 is squeezed and deformed by the first positioning block 31, stress will be generated inside the first hook 32, causing mechanical fatigue of the first hook 32 after repeated use, affecting the subsequent rebound, thereby affecting the service life of the first expansion component 3. Therefore, an elastic component 12 is provided between the first hook 32 and the tray body 1. The elastic component 12 is used to provide elastic deformation to the first hook 32 to avoid fatigue of the first hook 32 after multiple deformations, thereby effectively ensuring the service life of the first expansion component 3.
[0042] In order to increase the service life of the wooden pallet, the second hook 42 of the second expansion component 4 is also provided with a corresponding chamfer 11 and an elastic component 12 .
[0043] In a further preferred embodiment of the present invention, Figure 3 As shown, the elastic component 12 is composed of a shell 121 and a spring piece 122. The top of the shell 121 is fixedly connected to the bottom of the tray body 1. The outer wall of the shell 121 is provided with a mounting groove 13 for rotatably connecting the first hook 32. The inner bottom wall of the mounting groove 13 is fixedly connected with the spring piece 122 in contact with the first hook 32.
[0044] In this embodiment, a sleeve 121 is provided, and a mounting groove 13 for connecting the first hook 32 is opened in the sleeve 121, so that the first hook 32 can move slightly in the mounting groove 13 to avoid deformation of the first hook 32 when it is rigidly connected to the tray body 1 and squeezed.
[0045] By providing a spring sheet 122 between the bottom of the first hook 32 and the mounting groove 13, the elasticity of the spring sheet 122 can be utilized to ensure that the first hook 32 has sufficient elastic force to rebound when being squeezed downward, so that the first hook 32 can be stably inserted into the first groove 7, thereby ensuring the connection stability of the wooden pallet expansion.
[0046] 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.
