Description

Technical Field

[0001] The utility model relates to the technical field of pallet boxes, in particular to a pallet box with a nested anti-pressure function. Background Technique

[0002] A pallet box is a large material loading box manufactured on the basis of a material pallet, and the pallet box is suitable for factory turnover and product storage.

[0003] There is a existing pallet box with a nested anti-pressure function (application number: 202320393016.8), which enables the goods in the box not to be squeezed when the boxes are nested, prevents the goods from being damaged, and can nest more boxes at one time to transport more goods. However, there are still some problems. When using the pallet box to hold items, multiple pallet boxes are often stacked. The above device is provided with support bars inside the box body. When the boxes are nested, the box body can be supported, and at the same time, the items inside the box body are prevented from being squeezed. Since the heights of the objects placed in the box body are different, the above device adjusts by changing the position of the groove into which the support bar is inserted. Due to the setting of the groove, the position where the support bar can be installed is fixed, which is not convenient to adjust the position of the support bar exactly to the top of the item, thus easily causing waste of space. And after the boxes are nested, it is not convenient to clamp the nested boxes. Therefore, during transportation, the nested boxes are prone to relatively strong shaking on the inner wall of the lower box, and the placement stability is poor. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that it is not convenient to adjust the position of the support bar exactly to the top of the item, which easily causes waste of space, and it is not convenient to clamp the nested boxes. Therefore, during transportation, the nested boxes are prone to relatively strong shaking on the inner wall of the lower box, and the placement stability is poor, and a pallet box with a nested anti-pressure function is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] Design a pallet box with a nested anti-pressure function, including a box body. An item is attached to the bottom of the inner wall of the box body. A support bar is in clearance fit with a through groove above one side of the inner wall of the box body. A vertical cylinder is fixedly connected above one side of the box body, and a moving structure is arranged on one side of the vertical cylinder.

[0007] Preferably, the moving structure includes a threaded rod, the lower outer wall of the threaded rod is threadedly connected to the bottom inner wall of the vertical cylinder, the top of the threaded rod is rotatably connected to a curved plate through a bearing, one outer wall side of the curved plate is in clearance fit with the top inner wall of the vertical cylinder, the other outer wall side of the curved plate is in clearance fit with the top side inner wall of the box body, and one side below the curved plate is fixedly connected to one end of a support bar.

[0008] Preferably, a curved block is in clearance fit with the top groove of the support bar.

[0009] Preferably, one end of the curved block is fixedly connected to a spring, and one end of the spring is fixedly connected to the top groove of the support bar.

[0010] Preferably, the other end of the curved block is fixedly connected to a clamping plate.

[0011] Preferably, square grooves are processed at both the front and rear ends of the box body.

[0012] A card board box with a nested anti - pressure function proposed by the present utility model has the beneficial effects that: through the cooperation of the box body, the vertical cylinder, the support bar and the moving structure, when the device is in use, by rotating the threaded rod, the threaded rod drives the curved plate to move up and down, the curved plate drives the support bar to move up and down. After adjusting the support bar to a suitable position, the box bodies to be nested are placed on the top of the support bar, thereby realizing nesting and avoiding squeezing the items, facilitating adjusting the position of the support bar just to the top of the items, and thus avoiding wasting space;

[0013] Through the cooperation of the support bar, the curved block, the spring and the clamping plate, when the device is in use, by placing the nested box bodies on the top of the support bar, the spring drives the curved block to move inwards, the curved block drives the clamping plate to move inwards, and the clamping plate clamps the nested box bodies, facilitating clamping the nested box bodies and avoiding relatively strong shaking of the nested box bodies on the inner wall of the lower box body during transportation, improving the placement stability.

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] Embodiment 1:

[0023] See attached Figure 1-6 The top groove of the support bar 3 is equipped with a curved block 5, and the top groove of the support bar 3 is equipped with a spring 6, which gives the curved block 5 an inward force, and one end of the spring 6 is fixedly connected to the top groove of the support bar 3, and the other end of the curved block 5 is fixedly connected to the clamping plate 4. The front and rear ends of the box body 1 are processed with square grooves 9, which are convenient for carrying the box body 1. A movable structure 2 is provided on one side of the vertical tube 7. The movable structure 2 is convenient for adjusting the position of the support bar 3 to the top of the article 8, thereby avoiding wasting space.

[0024] The movable structure 2 includes a threaded rod 2a2, the outer wall of which is threadedly connected to the bottom inner wall of the vertical tube 7 at the bottom, and the top of the threaded rod 2a2 is rotatably connected to a curved plate 2a1 through a bearing. The bearing allows the threaded rod 2a2 to rotate at the bottom end of the curved plate 2a1 when a force is applied. One side of the outer wall of the curved plate 2a1 is gap-matched with the top inner wall of the vertical tube 7. The top inner wall of the vertical tube 7 limits the curved plate 2a1 when it is moved under a force. The other side of the outer wall of the curved plate 2a1 is gap-matched with the top inner wall of the box body 1. The lower side of one side of the curved plate 2a1 is fixedly connected to one end of the support bar 3, so that the position of the support bar 3 can be adjusted to the top of the object 8, thereby avoiding waste of space.

[0025] Working principle:

[0026] When the box 1 is nested using the pallet box with nesting and anti-pressure function:

[0027] Place the item at the bottom of the inner wall of the box body 1, rotate the threaded rod 2a2, the threaded rod 2a2 drives the curved plate 2a1 to move up and down, the curved plate 2a1 drives the support bar 3 to move up and down. After adjusting the support bar 3 to the appropriate position, place the box body 1 to be nested on the top of the support bar 3. The spring 6 drives the curved block 5 to move inward, the curved block 5 drives the clamping plate 4 to move inward, and the clamping plate 4 clamps the nested box body 1, thereby realizing nesting and avoiding squeezing the item 8.

[0028] Embodiment 2:

[0029] Refer to the attached Figure 1-6 : In this embodiment, a pallet box with a nesting and anti-pressure function, wherein the moving structure 2 may further include a rubber pad 2b1, and one end of the rubber pad 2b1 is fixedly connected to the rubber pad 2b1.

[0030] Working principle:

[0031] When the clamping plate 4 clamps the nested box body 1, the rubber pad 2b1 is in contact with the outer wall side of the nested box body 1, thereby increasing the friction force.

[0032] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
