[0001] The utility model relates to the field of pallets, in particular to a new type of pallet. Background Art

[0002] When the pallets are not loaded with goods, the pallets are stacked together in a straight line from top to bottom to reduce the space occupied by multiple pallets when stored. At this time, the foot pier of the upper pallet is inserted into the cavity of the foot pier of the lower pallet, and the corner of the foot pier of the upper pallet (the junction of the outer side and the bottom surface) contacts the inner side of the foot pier of the lower pallet.

[0003] When stacking, there will be multiple upper piers inside a pier. The larger the opening of the pier is, the easier it is for the pier at the bottom to be cracked and damaged under pressure. The generatrix of the inner wall of the existing pier is an arc line, which has the limitation that the opening cannot be reduced.

[0030] like Figures 1 to 7 As shown, this embodiment provides a new type of pallet, including: a load-bearing portion 1 and a foot pier 2, wherein the load-bearing portion 1 is located above the foot pier 2 and is integrally formed with a plurality of foot piers 2, wherein an inner cavity opening upward is formed inside the foot pier 2, and the inner and outer sides of the side walls 21 of the foot pier 2 are inclined inward from top to bottom, and the inner side of the side wall 21 includes a first curved surface 212 and an inclined surface 213, wherein the inclined surface 213 is located above the first curved surface 212. The inclined surface 213 reduces the opening area of ​​the first curved surface 212, which is beneficial to reducing the horizontal force on the foot piers when they are stacked, thereby allowing the foot piers 2 to be stacked in more layers. Among them, the load-bearing portion 1 is used to carry goods,

[0031] Furthermore, the footrest 2 includes a side wall 21 and a bottom 22 , and the lower end of the side wall 21 and the bottom 22 are integrally formed.

[0032] Furthermore, the included angle between the generatrix of the inclined surface 213 and the tangent of the upper end of the generatrix of the first curved surface 212 is between -5 degrees and +5 degrees, that is, the inclined surface 213 is deflected inwardly or outwardly within 5 degrees relative to the first curved surface 212 .

[0033] Further, the angle between the generatrix of the inclined surface 213 and the tangent of the upper end of the generatrix of the first curved surface 212 is 0 degrees. Preferably, the lower end of the inclined surface 213 coincides with the upper end of the first curved surface 212. At this time, the generatrix of the inclined surface 213 is tangent to the generatrix of the first curved surface 212.

[0034] Furthermore, the generatrix of the outer side surface of the side wall 21 is wavy. The wavy outer side surface has higher strength, and the multiple circles of annular protrusions in the horizontal direction play the role of reinforcing ribs.

[0035] Furthermore, the wavelength of the middle part of the wavy busbar on the outer side is smaller than the wavelength above and below it. The wavelength in physics is used here to describe the state of the wavy busbar, that is, the spacing between the two annular protrusions in the middle is smaller than the spacing between the two annular protrusions above and below. The wavy outer side with variable spacing has higher strength and bearing capacity than the foot pier 2 with equal spacing.

[0036] The spacing between two adjacent annular protrusions can increase gradually from the middle to the top and to the bottom; it can also be divided into three upper, middle and lower areas, the spacing between the two annular protrusions in each area is equal, and the spacing in the middle is the smallest; or in one or two of the three areas, the spacing between the two annular protrusions in the same area is equal, and the spacing between the two annular protrusions in the remaining areas changes successively.

[0037] Furthermore, the upper side surface of the bottom 22 is a curved surface, the upper side surface of the bottom 22 is tangent to the first curved surface 212, and the lower side surface of the bottom 22 is a plane, which is convenient for fitting with a placement plane such as the ground.

[0038] Furthermore, the generatrix of the first arc surface 212 is a circular arc, and the generatrix of the inclined surface 213 is a straight line.

[0039] Furthermore, the bearing part 1 and the footrest 2 are molded from fiber materials. Preferably, the fiber materials are wood fibers.

[0040] Furthermore, the bearing portion 1 is formed with a limiting protrusion 14 and a limiting groove 15, wherein the limiting groove 15 is located above the limiting protrusion 14, and the limiting groove 15 is adapted to the shape below the limiting protrusion 14, so as to limit the horizontal movement of the upper and lower trays when stacking. When stacking, the limiting protrusion 14 of the upper tray is inserted into the limiting groove 15 of the lower tray, and the bottom surface of the limiting protrusion 14 contacts the bottom of the limiting groove 15, playing a supporting role, increasing the overall contact area, and reducing the pressure of the foot 2.

[0041] Furthermore, the bearing portion 1 is formed with a guide protrusion 17 near the edge, and the protrusion 17 is formed with an inclined guide surface 171 on one side near the edge. The lower end of the guide surface 171 is inclined toward the inner side of the bearing portion 1, and the inclined guide surface 171 is used to guide the fork of the forklift to prevent the fork from directly contacting the side of the vertical reinforcing rib, causing the fork to pierce the reinforcing rib.

[0042] Furthermore, the number of the foot blocks 2 is 9, and the 9 foot blocks 2 are arranged in a dot matrix of 3 rows and 3 columns. Among them, 4 foot blocks 2 are located at the corners of the bearing part 1, 4 foot blocks 2 are located in the middle of the edge of the bearing part 1, and 1 foot block 2 is located in the middle of the bearing part 1.

[0043] Furthermore, the bearing portion 1 is formed with a first reinforcing rib 11 , and two ends of the first reinforcing rib 11 are respectively connected to the inside of the foot pier 2 in the middle of the bearing portion 1 and the inside of the foot pier 2 at the corner of the bearing portion 1 .

[0044] Furthermore, the bearing part 1 is formed with a second reinforcing rib 12, one end of the second reinforcing rib 12 is connected to the foot pier 2 in the middle of the sideline of the bearing part 1, and the other end is closed. Preferably, the foot pier 2 points to the foot pier 2 in the middle.

[0045] Furthermore, the bearing portion 1 is formed with a third reinforcing rib 13, the third reinforcing rib 13 is located between the first reinforcing rib 11 and the second reinforcing rib 12, and both ends of the third reinforcing rib 13 are closed. Preferably, the third reinforcing rib 13 is parallel to the second reinforcing rib 12.

[0046] Furthermore, the bearing portion 1 is formed with a fourth reinforcing rib 16, one end of the fourth reinforcing rib 16 is connected to the foot pier 2 at the corner, and the other end is closed. The foot pier 2 at a corner is connected to two fourth reinforcing ribs 16, and the two fourth reinforcing ribs 16 are symmetrical about the first reinforcing rib 11 connected to the foot pier 2. Preferably, the protrusion 17 is located at the bend of the fourth reinforcing rib 16 and is connected to the fourth reinforcing rib 16.

[0047] Among them, the first reinforcing rib 11 comprehensively strengthens the pallet as a whole to prevent the pallet from cracking at the four corners; the second reinforcing rib 12 is used to ensure the structural strength of the middle part; the third reinforcing rib 13 is used to assist the first reinforcing rib 11 in strengthening the pallet as a whole; the fourth reinforcing rib 16 has higher bending strength and is not easily broken.

[0048] When stacking, the trays are placed one on top of the other from top to bottom. The foot pier 2 of the upper tray is inserted into the foot pier 2 of the lower tray, and the upper outer side surface contacts the lower inner side surface. At this time, the upper limiting protrusion 14 contacts the lower limiting groove 15, playing a supporting role.

[0049] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
