First preferred embodiment

Referring first to fig. 1, 2, 3 and 4, the pallet 100 of the first preferred embodiment of the present invention is generally comprised of a base assembly, a carrier assembly and a support assembly. Wherein the base assembly is for placement on a ground surface. The carrier assembly is located above the base assembly, preferably spaced apart, for carrying cargo thereon. The supporting component is positioned between the two, and the supporting component is opened and closed to support the bearing component.

Specifically, the tray 100 is preferably configured to be rectangular. More preferably, the tray 100 is configured as a square. The base assembly includes a bottom frame 150 disposed along a circumference of the tray 100. Alternatively, the bottom frame 150 is also formed in a square shape. Wherein the bottom frame 150 can be made of pipes by splicing and welding, such as a round steel pipe. Preferably, the bottom frame 150 is made of four tubes by splicing or welding, and the two ends of the tubes are designed as male and female sleeves so as to facilitate insertion. Preferably, at least one set of opposite pipes of the bottom frame 150 is provided with a scoop. For example, the bottom of at least one set of opposing tubes of the bottom frame 150 may be partially concave or flattened to allow space for the forks of a ground cow to pass through.

The support assembly comprises a first load beam 101, a second load beam 102 and four second bearers 140. Wherein the first load beam 101 comprises two load bearing units 110 and a first carrier 130. Specifically, the two load bearing units 110 are connected with the first support 130, and the first support 130 is located between the two load bearing units 110.

The second girder 102 comprises two abutting load bearing units 110. The load-bearing unit 110, the first support 130 and the second support 140 are each constructed as an integral stamping. And the size of the stamping part can be changed by adjusting the die.

Wherein, the specific structure of the load bearing unit 110 refers to fig. 1 and 2, which includes a main beam portion 111 and a support portion 112. The main beam portion 111 extends in the longitudinal direction or the width direction of the tray 100. The support portion 112 is located at an end of the main beam portion 111, and is configured as an inverted trapezoid recessed downward to contact the base assembly, or the bottom frame 150. Illustratively, the inverted trapezoid is preferably a right-angled trapezoid. Therefore, the inverted trapezoidal support portion 112 can have a vibration damping effect, and can effectively alleviate external force impact.

Specifically, the support portion 112 includes a bevel portion 113, a bottom edge portion 114, and side edge portions 115. The diagonal portion 113 is connected to the main beam portion 111. Which extends obliquely downward from the end of the main beam portion 111. The beveled portion 113 generally forms the beveled edge of an inverted trapezoid. The bottom edge portion 114 is connected to the beveled edge portion 113, which is preferably horizontally disposed. Or the bottom side portion 114 is horizontally disposed at an end portion of the bevel portion 113 away from the main beam portion 111. The bottom edge portion 114 substantially constitutes a narrow bottom of an inverted trapezoid. The side edge portions 115 are connected to the bottom edge portion 114, which is preferably vertically disposed. Thus, it may substantially constitute a straight side or a height of the inverted trapezoid. In other words, the side edge portion 115 is vertically provided at an end portion of the bottom edge portion 114 distant from the bevel edge portion 113. Wherein the main beam portion 111 and the hypotenuse portion 113 are configured as a corrugated plate to improve structural strength. And the combination of the corrugated plate and the inverted right trapezoid can ensure the strength of the whole structure and can also effectively play a role in vibration reduction.

Preferably, the bottom surface of bottom edge 114 is provided with a first groove 116 and a second groove 117. Wherein the first groove 116 and the second groove 117 are both upwardly concave. Also, the first groove 116 extends in a direction perpendicular to the main beam portion 111, and the second groove 117 is disposed orthogonally to the first groove 116. Alternatively, the second groove 117 extends perpendicularly with respect to the first groove 116.

In the present embodiment, the first bearing beam 101 and the second bearing beam 102 are arranged to intersect. Preferably orthogonally arranged. Or, the first load beam 101 and the second load beam 102 are perpendicular to each other. Wherein the second load bearing beam 102 is located between the two load bearing units 110 of the first load bearing beam 101.

And, the first and second load-

bearing beams

101 and 102 are disposed on the bottom frame 150. The first bearing beam 101 and the second bearing beam 102 are perpendicular to two sets of opposite sides of the top frame 121. Specifically, the two support portions 112 of the first and second load-

bearing beams

101 and 102 are respectively located at the middle points of the four sides of the square bottom frame 150. Thus, the four first grooves 116 of the four support portions 112 of the first and second bearing beams 101 and 102 are respectively overlapped with one edge of the bottom frame 150, and thus the pipe constituting the bottom frame 150 can be inserted into the first grooves 116. Thus, the stability and firmness of installation can be improved.

Referring to fig. 1 and 3, the first support 130 is disposed at the middle of the first bearing beam 101 and protrudes downward from the main beam 111 to be connected to the base assembly.

More specifically, referring to fig. 3, the first holder 130 includes a first sidewall 131, a second sidewall 132, a bottom wall 133, a first connection portion 134, and a second connection portion 135. Wherein the first sidewall 131 and the second sidewall 132 are oppositely disposed in a vertical direction. The bottom wall 133 is connected between the bottom end of the first side wall 131 and the bottom end of the second side wall 132. The first connecting portion 134 is horizontally disposed at a top end of the first sidewall 131 and extends in a direction away from the second sidewall 132. The second connecting portion 135 is horizontally disposed at the top end of the second sidewall 132 and extends toward a direction away from the first sidewall 131. That is, the first connection portion 134 and the second connection portion 135 extend opposite to each other. Wherein the first connection portion 134 and the second connection portion 135 are respectively used for connecting, for example welding or screwing, with the two main beam portions 111 of the two load bearing units 110 of the first load bearing beam 101. Therefore, when the first bearing beam 101 and the second bearing beam 102 are arranged to intersect, the second bearing beam 102 can pass through between the first connecting portion 134 and the second connecting portion 135 of the first support 130, so that the interference between the corrugations on the first bearing beam 101 and the corrugations on the second bearing beam 102 is avoided, and the stable connection is difficult.

The bottom wall 133 is provided with a third recess 136 and a fourth recess 137 which are upwardly recessed. And are orthogonally or vertically arranged so as to extend in the same direction as the first and second intersecting

load bearing beams

101 and 102, respectively. In other words, the bottom wall 133 is configured substantially square, and the third recess 136 and the fourth recess 137 are perpendicular to two sets of opposite sides of the bottom wall 133, respectively.

Preferably, the two second recesses 117 of the load bearing unit 110 of the first load bearing beam 101 are collinear with the third recess 136 and the fourth recess 137, respectively.

Referring to fig. 1, four second brackets 140 are respectively disposed at four corners of the bottom frame 150. The bottom of the second support 140 is connected to the bottom frame 150. The detailed structure of the second support 140 refers to fig. 4, which includes a first extension 141, a second extension 142, and a transition 143. The first extension 141 and the second extension 142 are disposed orthogonally to each other, or perpendicularly to each other. The transition portion 143 is connected between the first extension portion 141 and the second extension portion 142. And the first extending portion 141 and the transition portion 143, and the second extending portion 142 and the transition portion 143 are all smoothly transited. Therefore, the smooth transition right-angle design can achieve the effects of greatly improving the stability and relieving the impact.

In other words, the extending directions of the first extending portion 141 and the second extending portion 142 are parallel to or overlap with two vertical sides of the bottom frame 150, respectively. Preferably, outer sidewalls of the first and

second extensions

141 and 142 are configured as a corrugated plate to further improve load bearing strength.

With continued reference to FIG. 1, the carrier assembly includes a top frame 121 and a faceplate (not shown). The top frame 121 is configured substantially rectangular, preferably square, in shape. Or similar to the shape of the bottom frame 150, is also disposed along the circumferential direction of the tray 100. Preferably, the top frame 121 has a caulking groove opened inward. Alternatively, each side of the top frame 121 is provided with a U-shaped groove that is recessed in a horizontal direction and in a direction outward from the center of the tray 100. The panel is inserted into the insertion groove such that four sides of the panel are surrounded by the top frame 121, thereby improving the firmness of the connection.

In this case, when the panel is installed, three sides of the top frame 121 may be first spliced by using a profile, such as a light steel profile, and the panel is inserted and then spliced with the last side to complete the cladding. The panels may be constructed of fiberglass composite panels, bamboo-wood composite panels, stamped steel panels, or other types of composite panels, and the like.

In the present embodiment, four second holders 140 are also located at four corners of the top frame 121, i.e., the top surfaces of the second holders 140 are connected with the bottom of the top frame 121. Also, the end of the load bearing unit 110 is connected to the top frame 121. Specifically, the top of the side portions 115 of the support portion 112 at the ends of the load bearing unit 110 are connected to the top frame 121 to further support the load bearing assembly. Preferably, the main beam section 111 of the load bearing unit 110 may also be connected to the bottom surface of the panel to further improve the load bearing strength. Illustratively, the main beam section 111 may be welded or screwed to the panel.

The base assembly may further include a base plate 154, which is generally configured as a square plate conforming to the cross-sectional shape of the first holder 130 to be attached to the bottom side of the first holder 130.
