Description

Technical Field

[0001] The utility model relates to the technical field of display equipment, in particular to a turnover tray. Background Art

[0002] The back panel is a key component of display devices (such as TVs). Its product size is large and requires a dedicated pallet for storage.

[0003] At present, ordinary pallets can be used, which install the backboard by arranging the backboard positioning corner blocks on the pallet. When the backboard is stored, this kind of pallet cannot be stacked up, resulting in the backboard storage occupying a large amount of warehouse storage area and high storage costs.

[0004] And due to the special installation process of the back panel, the common folding storage cages on the market cannot be used. The reasons are as follows. The method of using the existing folding storage cage is: take the folded storage cage → unfold the folding mechanism → start loading into the cage → loading is completed → storage cage is transferred, stacked and stored → storage cage is taken out → taking out is completed → folding mechanism → storage cage is stored after folding; and the back panel installation and removal process is as follows: it is necessary to manually place the back panel positioning corner blocks on the pallet → manually take the back panel and place it on the back panel positioning corner blocks → buckle the new back panel positioning corner blocks on the original back panel positioning corner blocks → then install the new back panel, in this way, the back panels are stacked to complete the loading of the entire pallet. According to the stacking process, when the back panel is placed, there must be no interfering parts such as vertical beams around the pallet.

[0005] Therefore, a pallet is needed which takes up little space and is easy to load and take out.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0007] In view of the problems pointed out in the background technology, the utility model proposes a turnover pallet, which can be folded and unfolded by a folding / unfolding mechanism to facilitate stacking and storage when loaded or not loaded, thereby reducing the occupied space.

[0008] In order to achieve the above-mentioned utility model purpose, the utility model adopts the following technical solutions:

[0009] The present application relates to a turnover pallet, comprising:

[0010] A bottom frame, wherein stacking openings are respectively arranged at four bottom corners of the bottom frame;

[0011] A support frame, which is arranged above the base frame and forms a receiving space with the base frame, and the support frame is used to support a pallet on which articles are placed;

[0012] Four corner mounting parts, which are respectively arranged at the four corners of the base frame;

[0013] Two folding / unfolding mechanisms, including a left folding / unfolding mechanism and a right folding / unfolding mechanism;

[0014] The left folding / unfolding mechanism cooperates with the two corner mounting parts on the left side, and can be folded into the left side of the storage space and pulled out and unfolded to be perpendicular to the base frame. The front end and the rear end of the left folding / unfolding mechanism are each formed with a first left stacking foot and a second left stacking foot. The first left stacking foot is vertically upward and fits the stacking mouth when the left folding / unfolding mechanism is folded, and the second left stacking foot is vertically upward and fits the stacking mouth when the left folding / unfolding mechanism is unfolded;

[0015] The right folding / unfolding mechanism cooperates with the two corner mounting parts on the right side, and can be folded into the right side of the receiving space and pulled out and unfolded to be perpendicular to the base frame. A first right stacking foot and a second right stacking foot are formed at each of the front end and the rear end of the right folding / unfolding mechanism. The first right stacking foot is vertically upward and adapted to the stacking mouth when the right folding / unfolding mechanism is folded, and the second right stacking foot is vertically upward and adapted to the stacking mouth when the right folding / unfolding mechanism is unfolded.

[0016] The turnover pallet involved in the present application is arranged with a storage space and two folding / unfolding mechanisms. When no items are being circulated, the folding / unfolding mechanisms can be folded and stored in the storage space, and no other production space is occupied during use. At the same time, the pallets can be stacked high through the first left stacking feet at the two corners and the first right stacking feet at the two corners, so that the empty pallets can be stacked high when no items are being circulated, thereby reducing space occupation resources.

[0017] When the items are in circulation, the folding / unfolding mechanism is pulled out and unfolded into place. When a pallet is full of items, the items are stacked up through the second left stacking feet at the two corners and the second right stacking feet at the two corners. This enables full pallets to be stacked up when the items are in circulation, reducing the space occupied by the warehouse and improving space utilization.

[0018] In some embodiments of the present application, the stacking opening includes:

[0019] Stacking support columns, tops of which support corners of the chassis;

[0020] The stacking interface has a square top surface and four inclined planes, wherein the four inclined planes are inclinedly butted against four edges of the square top surface.

[0021] The square stacking interface is easy to match with the stacking feet to achieve stacking.

[0022] In some embodiments of the present application, the support frame includes:

[0023] A plurality of support beams are arranged vertically and horizontally above the base frame, and the corner mounting portions have mounting slots. The mounting slots of the two left corner mounting portions are used to support the leftmost support beam of the plurality of support beams, and the mounting slots of the two right corner mounting portions are used to support the rightmost support beam of the plurality of support beams.

[0024] The support frame structure formed by multiple support beams is stable and convenient for carrying more items, such as a backboard.

[0025] In some embodiments of the present application, the folding / unfolding mechanism includes:

[0026] A first beam and a second beam are opposite to each other, and a plurality of third beams are spaced and vertically connected between the first beam and the second beam. A stopper and a rotation axis are respectively provided on the outer sides of the first beam and the second beam in the front-back direction. The rotation axis is located at a spacing distance below the stopper and is located on the same straight line along the length direction of the beam. The height of the rotation axis extending away from the beam is greater than the height of the stopper extending away from the beam.

[0027] A limiting portion, which is used to limit the folding / unfolding mechanism folded into the accommodation space from coming out;

[0028] The corner mounting portion comprises:

[0029] A lateral mounting plate mounted to a corner of the chassis;

[0030] A transverse guide groove, which is provided on the inner side surface of the lateral mounting plate facing the folding / unfolding mechanism and extends in the left-right direction;

[0031] a vertical guide groove extending vertically through the transverse guide groove, so that the transverse guide groove is divided into an inner first sub-transverse guide groove and an outer second sub-transverse guide groove along the guiding direction, wherein the depth of the bottom wall of the first sub-transverse guide groove from the inner side surface is greater than the depth of the bottom wall of the second sub-transverse guide groove from the inner side surface;

[0032] A card slot, which is opened on the lateral mounting plate and is located directly above the vertical guide slot, and the opening of the card slot is vertically upward;

[0033] When the folding / unfolding mechanism is unfolded, the stopper and the rotating shaft are pulled out along the transverse guide groove and when the rotating shaft is embedded in the vertical guide groove, the folding / unfolding mechanism is rotated and folded upward to make the stopper stuck in the slot.

[0034] The present application realizes folding and unfolding of the folding / unfolding mechanism by setting a corresponding corner mounting structure and a folding / unfolding mechanism structure cooperating therewith, thereby realizing high stacking when the pallet is empty and high stacking when the pallet is full.

[0035] Furthermore, the folding / unfolding mechanism is fixed to the base frame via the corner mounting portion and cannot be removed, so there will be no problem of mechanism loss.

[0036] In some embodiments of the present application, the end of the first beam and the end of the second beam of the left folding / unfolding mechanism respectively form a second left stacking foot;

[0037] The end of the first beam and the end of the second beam of the right folding / unfolding mechanism respectively form a second right stacking foot;

[0038] The end of the first beam and the end of the second beam of the left folding / unfolding mechanism are respectively provided with a first support leg and a second support leg extending vertically along the length direction thereof, and the end of the first support leg and the end of the second support leg of the left folding / unfolding mechanism respectively form a first left stacking foot;

[0039] The end of the first beam and the end of the second beam of the right folding / unfolding mechanism are respectively provided with a first support foot and a second support foot extending vertically along the length direction thereof, and the end of the first support foot and the end of the second support foot of the right folding / unfolding mechanism respectively form a second right stacking foot.

[0040] In some embodiments of the present application, the folding / unfolding mechanism further includes:

[0041] A handle is provided on the upper portion of the third beam at the uppermost end when the folding / unfolding mechanism is unfolded into place.

[0042] By providing a handle, it is convenient for the user to grasp when folding and unfolding the mechanism.

[0043] In some embodiments of the present application, the limiting portion is arranged on the inner side of the first beam or the second beam facing each other, so that when the folding / unfolding mechanism is folded, the limiting portion abuts against the inner side of the base frame; or

[0044] The limiting portion includes a first limiting portion and a second limiting portion, wherein the first limiting portion is arranged on the inner side surface of the first beam facing the second beam, and the second limiting portion is arranged on the inner side surface of the second beam facing the first beam, so that when the folding / unfolding mechanism is folded, the first limiting portion and the second limiting portion are both against the inner side of the base frame.

[0045] By providing the limiting portion, the folding / unfolding mechanism is prevented from escaping from the accommodating space after the folding / unfolding mechanism is folded into place, thereby ensuring that the folding is stable in place.

[0046] In some embodiments of the present application, the turnover pallet further includes:

[0047] A first forklift opening and a second forklift opening, wherein the first forklift opening and the second forklift opening are arranged in parallel and have the same size as the front fork of a forklift.

[0048] By setting up a forklift opening, the turnover pallet can be easily moved.

[0049] In some embodiments of the present application, the first forklift opening and the second forklift opening are respectively large square steel pipes, which are welded in parallel to the bottom of the chassis.

[0074] In order to solve the problem of large space occupied by the pallet in the prior art, see Figures 1 to 13 , the present application relates to a turnover pallet.

[0075] The turnover pallet includes a base frame 100 , a support frame 300 , four corner mounting portions 600 , and two folding / unfolding mechanisms (including a left folding / unfolding mechanism 500 ′ and a right folding / unfolding mechanism 500 ).

[0076] The base frame 100 is the base of the entire turnover pallet. In some embodiments of the present application, the pallet is used for a turnover backplane, so the base frame 100 is designed to be square.

[0077] The square base frame 100 has four corners, and stacking openings 200 are respectively disposed at the four corners. The stacking openings 200 play a supporting role for the entire pallet.

[0078] In some embodiments of the present application, see Figure 2 The base frame 100 is a frame formed by a plurality of bottom beams arranged vertically and horizontally.

[0079] The chassis 100 includes a front bottom beam 110, a rear bottom beam 120, a left bottom beam 130, a right bottom beam 140, a plurality of middle longitudinal bottom beams 150 arranged in parallel between the front bottom beam 110 and the rear bottom beam 120 in the front-to-back direction, and a middle transverse bottom beam 160 arranged on the same straight line in the left bottom beam 130, the middle longitudinal bottom beam 150 and the right bottom beam 140 between adjacent beams.

[0080] The front, back, left, and right directions mentioned above are for ease of description only (see Figure 1 In the present application, the folding / unfolding mechanism is arranged on the left and right sides, the left side is the left folding / unfolding mechanism 500', and the right side is the right folding / unfolding mechanism 500.

[0081] See also Figure 2The stacking opening 200 is provided at a corner formed by two adjacent butted portions of the front bottom beam 110 , the rear bottom beam 120 , the left bottom beam 130 and the right bottom beam 140 .

[0082] In some embodiments of the present application, see Figure 1 and Figure 3 The support frame 300 is disposed above the base frame 100 and forms a receiving space between the support frame 300 and the base frame 100 .

[0083] The support frame 300 is used to support a support plate 400 on which items, such as a back plate, are placed.

[0084] When installing the backplane, first arrange the backplane positioning corner blocks at the corresponding four corners of the pallet 400, then install the backplane, and then install new backplane positioning corner blocks on the original backplane positioning corner blocks, and then install another backplane. In this way, the pallet can be filled.

[0085] In some embodiments of the present application, the support frame 300 is also a frame formed by a plurality of support beams arranged vertically and horizontally.

[0086] See also Figure 3 The support frame 300 includes a front support beam 310, a rear support beam 320, a left support beam 330, a right support beam 340, an intermediate longitudinal support beam 360 arranged between the front support beam 310 and the rear support beam 320 in the front-to-back direction, and an intermediate transverse support beam 350 arranged on the same straight line in the left support beam 330, the intermediate longitudinal support beam 360 and the right support beam 340 between adjacent beams.

[0087] See also Figure 1 and Figure 5 The corner mounting parts 600 are mounted at the four corners of the base frame 100 and have mounting notches 670 .

[0088] Return to see Figure 3 The mounting slots 670 of the two left corner mounting portions 600 are used to support the leftmost support beam of the multiple support beams, i.e., the left support beam 330; the mounting slots 670 of the two right corner mounting portions 600 are used to support the rightmost support beam of the multiple support beams, i.e., the right support beam 340.

[0089] The two ends of the left support beam 330 are respectively supported at the mounting notches 670 of the two left corner mounting parts 600 .

[0090] The two ends of the right support beam 340 are respectively supported at the mounting notches 670 of the two right corner mounting parts 600 .

[0091] In order to improve the support strength of the support frame 300, in some embodiments of the present application, see Figure 3 and Figure 4A reinforcing beam 370 is also provided which is arranged in the middle of the base frame 100 and the support frame 300 along the front-rear direction.

[0092] See also Figure 4 The lower surface of the reinforcing beam 370 contacts the middle longitudinal bottom beam 150 of the base frame 100 located in the middle position in the front-to-back direction, and the upper surface contacts the middle longitudinal support beam 360 of the support frame 300 located in the middle position in the front-to-back direction, so that the accommodating space formed between the base frame 100 and the support frame 300 can be divided into a left accommodating space 700 and a right accommodating space 800.

[0093] The left accommodation space 700 is used to accommodate the folded left folding / unfolding mechanism 500', and the right accommodation space 800 is used to accommodate the folded right folding / unfolding mechanism 500, see Figure 1 , Fig. 9 and Fig.10 .

[0094] In order to realize the folding and unfolding of the two folding / unfolding mechanisms, as described above, four corner mounting portions 600 are provided at the four corners of the base frame 100 .

[0095] The left folding / unfolding mechanism 500 ′ cooperates with the two corner mounting parts 600 on the left side to achieve folding and unfolding, and the right folding / unfolding mechanism 500 cooperates with the two corner mounting parts 600 on the right side to achieve folding and unfolding.

[0096] The structures of the left folding / unfolding mechanism 500 ′ and the right folding / unfolding mechanism 500 are the same.

[0097] As follows, the structure of the right folding / unfolding mechanism 500 is described as an example.

[0098] In some embodiments of the present application, see Figure 6 The folding / unfolding mechanism includes a first beam 510 , a second beam 520 and a plurality of third beams 530 .

[0099] The first beam 510 and the second beam 520 are arranged relatively parallel to each other, and a plurality of third beams 530 are arranged vertically and spaced apart between the first beam 510 and the second beam 520 along a direction parallel to the first beam 510 .

[0100] Stoppers and rotation shafts are respectively provided on outer sides of the first beam 510 and the second beam 520 in the front-rear direction.

[0101] Taking the first beam 510 as an example, see Figure 6 , which shows that a stopper 511 and a rotating shaft 512 are respectively provided on the outer side surface of the first beam 510 in the front-to-back direction.

[0102] The rotation axis 512 is located at a distance below the stopper 511 , and the stopper 511 and the rotation axis 512 are located on the same straight line along the length direction of the first beam 510 .

[0103] The height of the rotation axis 512 extending away from the first beam 510 is greater than the height of the stopper 511 extending away from the first beam 510. Figure 7 and Figure 8 .

[0104] The folding / unfolding mechanism needs to cooperate with the corner mounting portion 600 to achieve folding and unfolding. Therefore, in some embodiments of the present application, see Figure 5 The corner mounting portion 600 includes a first lateral mounting plate 610 and a second lateral mounting plate 620 connected thereto.

[0105] The corner where the first lateral mounting plate 610 and the second lateral mounting plate 620 meet is installed in alignment with the corner of the base frame 100 and wraps a portion of the stacking support column 210 of the stacking opening 200 at the corner.

[0106] The second lateral mounting plate 620 is formed with an escape portion 630 for facilitating the escape of the folding / unfolding mechanism when it is pulled out or folded. Fig. 9 .

[0107] A transverse guide groove 640 is formed on the inner side of the first lateral mounting plate 610 facing the folding / unfolding mechanism and extends in the left-right direction.

[0108] A vertical guide groove 650 is provided on the inner side of the first lateral mounting plate 610 facing the folding / unfolding mechanism (i.e., the right folding / unfolding mechanism 500), which vertically penetrates the transverse guide groove 640 so that the transverse guide groove 640 is divided into an inner first sub-transverse guide groove 641 and an outer second sub-transverse guide groove 642 along the guiding direction.

[0109] The depth of the bottom wall of the first sub-transverse guide groove 641 from the inner side surface of the first lateral mounting plate 610 is greater than the depth of the bottom wall of the second sub-transverse guide groove 642 from the inner side surface.

[0110] In this way, when the right folding / unfolding mechanism 500 is pulled out and unfolded, the rotating shaft 512 is guided and embedded in the vertical guide groove 650, so that the rotating shaft 512 cannot be pulled out from the vertical guide groove 650 while the right folding / unfolding mechanism 500 is pulled out, thereby ensuring that the right folding / unfolding mechanism 500 cannot be removed from the tray to avoid loss.

[0111] See also Figure 5 The card slot 660 is also provided on the first lateral mounting plate 610 and is located directly above the vertical guide slot 650 , and the opening of the card slot 660 is vertically facing upward.

[0112] By using the slot 660, the right folding / unfolding mechanism 500 is horizontally pulled out until the rotating shaft 512 is embedded in the vertical guide slot 650 (see Fig. 9 ), the right folding / unfolding mechanism 500 is turned upward to rotate around the rotating shaft 512, and the rotating shaft 512 is vertically guided upward along the vertical guide groove 650 until the stopper 511 passes through the opening of the slot 660 and is inserted into the slot 660, so that the vertical unfolding is completed, see Fig.10 .

[0113] In order to facilitate the user to fold and unfold the folding / unfolding mechanism, take the right folding / unfolding mechanism 500 as an example, see Figure 6 and Figure 7 A handle 540 is provided at the middle position of the third beam 530 located at the top, so as to facilitate the user to grasp and operate the right folding / unfolding mechanism 500 .

[0114] As follows, the folding and unfolding process of the lower right folding / unfolding mechanism 500 will be described.

[0115] In some embodiments of the present application, when unfolding, the user grasps the handle 540 and pulls the right folding / unfolding mechanism 500 horizontally to the right (for the left folding / unfolding mechanism 500 ′, pull it to the left).

[0116] During the horizontal pulling process, since the height of the rotating shaft 512 is higher than the height of the stop block 511, the rotating shaft 512 slides outward along the first sub-transverse guide groove 641 until it is embedded in the vertical guide groove 650, and then stops being pulled out horizontally. At this time, the stop block 511 has been guided to slide out to the outside through the second sub-transverse guide groove 642.

[0117] Afterwards, the user grasps the handle 540 to flip the right folding / unfolding mechanism 500 upward. During the flipping process, the right folding / unfolding mechanism 500 rotates around the rotating axis 512 while being guided upward along the vertical guide groove 650 until it stops when the stop block 511 is located directly above the slot 660. Afterwards, the right folding / unfolding mechanism 500 is pressed down so that the stop block 511 is stuck in the slot 660 to achieve full unfolding.

[0118] The folding process is the reverse of the unfolding process.

[0119] When folding, the user grasps the handle 540 and pulls the right folding / unfolding mechanism 500 upward to disengage the stopper 511 from the slot 660 .

[0120] During the upward pulling process, the right folding / unfolding mechanism 500 is folded downward until it is folded to a horizontal direction. At this time, the stopper 511 is directly opposite to the transverse guide groove 640 .

[0121] Afterwards, the user pushes inward with force, so that the rotating shaft 512 disengages from the vertical guide groove 650 and enters the first sub-transverse guide groove 641 , and moves along the first sub-transverse guide groove 641 until it is folded into place, that is, pushed to the right accommodating space 800 .

[0122] To ensure that the right folding / unfolding mechanism 500 is folded in place and stable, see Figure 6 , a limiting portion 570 is arranged on the right folding / unfolding mechanism 500.

[0123] The limiting portion 570 is used to abut against the inner side surface of the bottom frame 100 after the right folding / unfolding mechanism 500 is folded into place, thereby limiting the stability of the right folding / unfolding mechanism 500 when folded into place.

[0124] In some embodiments of the present application, the limiting portion may be a limiting block.

[0125] The limit block can be set on the inner side surface of the first beam 510 or the second beam 520 of the right folding / unfolding mechanism 500 facing each other, and is used to abut against the inner side of the base frame 100, specifically against the inner side surface of the corresponding side bottom beam of the base frame 100, when the right folding / unfolding mechanism 500 is folded, to limit the right folding / unfolding mechanism.

[0126] In some embodiments of the present application, see Figure 6 The limiting portion 570 may also include a first limiting block 571 and a second limiting block 572 .

[0127] The first limiting block 571 is disposed on the inner side surface of the first beam 510 of the right folding / unfolding mechanism 500 facing the second beam 520 .

[0128] The second limiting block 572 is disposed on the inner side surface of the second beam 520 of the right folding / unfolding mechanism 500 facing the first beam 510 .

[0156] See also Fig.12 When empty pallets are stacked up and down, the left front stacking opening of the upper turnover pallet is put on the left front stacking foot of the lower turnover pallet, the left rear stacking opening of the upper turnover pallet is put on the left rear stacking foot of the lower turnover pallet, the right front stacking opening of the upper turnover pallet is put on the right front stacking foot of the lower turnover pallet, and the right rear stacking opening of the upper turnover pallet is put on the right rear stacking foot of the lower turnover pallet.

[0157] In some embodiments of the present application, in order to facilitate the placement of the turnover pallet, see Figure 1 , Figure 3 and Fig.12 and Fig.13 The turnover pallet further includes a first forklift opening 900 and a second forklift opening 900 ′.

[0158] The first forklift opening 900 and the second forklift opening 900 ′ are arranged in parallel at the bottom of the chassis 100 and have the same size as the front fork of a forklift, so that it is convenient for a forklift to stack the turnover pallets.

[0159] In some embodiments of the present application, the first forklift opening 900 and the second forklift opening 900 ′ are respectively large square steel pipes, which are welded to the bottom of the chassis 100 in parallel.

[0160] The turnover pallet involved in the present application facilitates the storage of the pallet through the left folding / unfolding mechanism 500' and the right folding / unfolding mechanism 500 to avoid occupying a large space, and when loading, the folding / unfolding mechanism is folded and stored in the storage space (see Fig.12 ), avoid interference around the installation, and facilitate installation.

[0161] The pallet can be stacked high with empty and full pallets (see Fig.12 and Fig.13 ), improve warehouse utilization; and the pallet has a special stacking mouth 200 and a stacking foot, the stacking is stable, it is convenient for transportation and will not cause safety hazards caused by lateral tilting.

[0162] The left folding / unfolding mechanism 500' and the right folding / unfolding mechanism 500 in the tray are respectively fixed to the base frame 100 through the corner mounting parts 600 and are not removable, so there will be no problem of loss of the folding / unfolding mechanism. When folded, they can be stored in the storage space and will not occupy other production space during use.

[0163] The following describes the method of using the turnover pallet.

[0164] Step 1: Take the turnover pallet, see Figure 1 .

[0165] The folded pallet is forked by a forklift at the forklift opening and placed at the appropriate position at the bottom of the backplane production line.

[0166] Step 2: Arrange and pack.

[0167] The back panel positioning corner blocks and the back panel are manually stacked neatly on the pallet 400 of the pallet to complete the stacking of the product pieces. After the product stacking is completed, it is wrapped and packaged.

[0168] Step 3: Open the folding / unfolding mechanism.

[0169] After the product pieces are stacked and packaged, the left folding / unfolding mechanism 500' and the right folding / unfolding mechanism 500 folded in the accommodation space are manually unfolded. Fig.10 .

[0170] The unfolding process of the right folding / unfolding mechanism 500 is described as follows: the user grasps the handle 540 and pulls the right folding / unfolding mechanism 500 horizontally to the right.

[0171] During the horizontal pulling process, since the height of the rotating shaft 512 is higher than the height of the stop block 511, the rotating shaft 512 slides outward along the first sub-transverse guide groove 641 until it is embedded in the vertical guide groove 650, and then stops being pulled out horizontally. At this time, the stop block 511 has been guided to slide out to the outside through the second sub-transverse guide groove 642.

[0172] Afterwards, the user grasps the handle 540 to flip the folding / unfolding mechanism upward. During the upward flipping process, the folding / unfolding mechanism rotates around the rotating axis 512 while being guided upward along the vertical guide axis until the stop block 511 is located directly above the slot 660 and stops. Afterwards, the folding / unfolding mechanism is pressed down so that the stop block 511 is stuck in the slot 660 to achieve full unfolding.

[0173] The unfolding process of the left folding / unfolding mechanism 500 ′ is similar.

[0174] Step 4: Packing, transportation and storage.

[0175] The forklift transports the pallet with the folding / unfolding mechanism opened and the product pieces stored therein to the warehouse for storage. Two pallets can be stacked through the stacking opening 200, see Fig.13 .

[0176] Step 5: Fold the folding / unfolding mechanism and go online to pick up the items.

[0177] Forklifts transfer the pallets stacked in the warehouse to the assembly line for picking up and assembling.

[0178] The user grasps the handle 540 and pulls the right folding / unfolding mechanism 500 upward to disengage the stopper 511 from the slot 660 .

[0179] During the upward pulling process, the right folding / unfolding mechanism 500 is folded downward until it is folded to a horizontal direction. At this time, the stopper 511 is opposite to the transverse guide groove 640 .

[0180] Afterwards, the user pushes inward with force, so that the rotating shaft 512 disengages from the vertical guide groove 650 and enters the first sub-transverse guide groove 641, and moves along the first sub-transverse guide groove 641 until it is folded into place, that is, pushed to the accommodating space, and the limit block on the folding / unfolding mechanism abuts against the inner side of the base frame 100, so as to achieve firm storage and prevent it from falling out.

[0181] The folding process of the left folding / unfolding mechanism 500 ′ is similar.

[0182] At this time, you can pick up the item.

[0183] Step 6: Fold the tray for storage.

[0184] The forklift transports the folded pallet to the warehouse area, and multiple pallets can be stacked through the stacking opening 200 and the stacking feet. Fig.12 .

[0185] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0186] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
