[0026] As Figures 1 to 7As shown, a foldable stackable pallet includes a pallet base frame 1. Two symmetrical support legs 7 are arranged on the bottom of both sides of the pallet base frame 1. Support grooves 3 are staggered at the top of the two support legs 7 on the same side of the pallet base frame 1. The support grooves 3 are U-shaped grooves, and their opening directions are opposite. A stop bar 2 is provided inside the support groove 3. One side of the stop bar 2 is slidably and rotatably connected to the support groove 3. A slot (not shown in the diagram) matching the end of the stop bar 2 is provided at the top of the support leg 7. An anti-detachment blocking mechanism 4 is provided on one side of the support groove 3. The anti-detachment blocking mechanism 4 has a bolt 43, and a locking hole 21 corresponding to the bolt 43 is provided on one side of the stop bar 2. When the end of the stop bar 2 is inserted into the bolt 43... When the end of the stop bar 2 is inserted into the slot of the support leg 7, the bolt 43 is inserted into the locking hole 21 to lock the stop bar 2 and the support groove 3. In this embodiment, when the end of the stop bar 2 is inserted into the slot of the support leg 7, the support leg 7 supports the stop bar 2 from all sides, and at the same time, the support groove 3 supports the stop bar 2 on three sides, which can make the stop bar 2 have high stability and not easily swing during use. When the end of the stop bar 2 is inserted into the slot, the bolt 43 in the anti-disengagement blocking mechanism 4 is inserted into the locking hole 21 to lock the stop bar 2 and the support groove 3, so that the end of the stop bar 2 will not come out of the slot of the support leg 7, ensuring the stability of the stop bar 2. When encountering bumps, the stop bar is not easy to come out of the slot, ensuring transportation efficiency.

[0027] In some embodiments, such as Figures 2 to 5 As shown, the anti-detachment blocking mechanism 4 also has a slide cylinder 41. A fixing ring 42 is provided on the outer side of one end of the slide cylinder 41, and a retaining ring 47 is provided on the inner side of one end of the slide cylinder 41. The plug 43 is slidably disposed inside the fixing ring 42 and the retaining ring 47. A sliding plate 46 is fixedly disposed on the outer side of the plug 43 inside the slide cylinder 41. A spring 45 is fitted on the outer side of the plug 43 between the sliding plate 46 and the retaining ring 47. The fixing ring 42 is fixedly disposed on the outer side of the support groove 3.

[0028] When the bolt 43 is inserted into the locking hole 21, the spring 45 applies elastic force to the slide plate 46, keeping the bolt 43 inserted into the locking hole 21. When it is necessary to fold the lever 2, pull the bolt 43 to compress the spring 45, so that the end of the bolt 43 is pulled out from the locking hole 21. At this time, the lever 2 can be pulled up and folded.

[0029] In some embodiments, in order to facilitate pulling the plug 43, a pull ring 44 is provided on the end of the plug 43 that is away from the support groove 3.

[0030] In some embodiments, in order to further improve the stability of the connection between the rod 2 and the support groove 3, the upper end of the support groove 3 is provided with a fixed slot 31, and one side of the rod 2 is threadedly connected with a fixed bolt 22 corresponding to the fixed slot 31; when the end of the rod 2 is inserted into the slot, the fixed bolt 22 enters the inside of the fixed slot 31; at this time, the fixed bolt 22 is locked, so that the rod 2 and the support groove 3 are fixedly assembled together through the fixed bolt 22, thereby improving the stability of the connection between the rod 2 and the support groove 3.

[0031] In some embodiments, one side of the support groove 3 is provided with a guide groove 5, and one side of the rod 2 is provided with a sliding rod 6 matched with the guide groove 5; the sliding rod 6 is slidingly and rotatably arranged in the guide groove 5, and the guide groove 5 limits and guides the movement path of the sliding rod 6, thereby limiting the movement range of the end of the support groove 3 in the inside of the support groove 3.

[0032] In some embodiments, the guide groove 5 has a vertical sliding section 51, and the upper end of the vertical sliding section 51 is provided with an inclined sliding section 52 in communication therewith; the inclined sliding section 52 is inclined towards the folding direction of the rod 2; the sliding rod 6 cooperates with the vertical sliding section 51, so that the rod 2 can move up and down in the inside of the support groove 3; the sliding rod 6 cooperates with the inclined sliding section 52, so that the rod 2 can move a certain distance away from the inside of the support groove 3, thereby reserving enough space for the swinging of the bottom end of the rod 2 when the rod 2 is folded.

[0033] In some embodiments, both sides of the tray bottom frame 1 are fixedly provided with a bracket 8 corresponding to the rod 2; the bracket 8 is an L-shaped plate body, one end of the bracket 8 is fixedly connected with the bottom of the tray bottom frame 1, and the bracket 8 supports the rod 2 below after the rod 2 is folded.

[0034] Thus far, the embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description.

[0035] The above-described embodiments only express some implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
