Description

Technical Field

[0001] The utility model relates to the technical field of plastic frames, and specifically provides a side plate and a turnover basket. Background Art

[0002] Plastic frames are common storage devices, such as those used to store parts in factories or vegetables in markets. When not in use, plastic frames are large and inconvenient to store. Therefore, there are foldable plastic frames, also known as folding baskets, in the prior art. Folding baskets can reduce the volume of the plastic frame by folding, making it easier to store and transport. Folding baskets usually include a base and four side panels, wherein the side panels are hingedly connected to the base. When folding is required, the side panels can be folded toward the inside of the folding basket so that the four side panels overlap with the base, thereby reducing the volume of the folding basket. In order to achieve hinged connection with the base, a hinge shaft is usually provided at the bottom of the side panel, and a junction groove is provided at the base. The hinge shaft is connected to the hinge groove to achieve a hinged connection between the side panel and the base. It should be noted that when the hinge shaft needs to be assembled into the hinge groove, the opening of the hinge groove is usually set on the side of the hinge groove, and then the hinge shaft is assembled into the hinge groove from the opening on the side of the hinge groove. For example, the assembly method disclosed in the application number 20202309423.8, entitled "An Intelligent and Environmentally Friendly Folding Storage Basket", has an opening on the side of the hinge groove, so that the hinge shaft can be installed into the hinge groove from the opening on the side.

[0003] However, when two opposing side panels are folded, the hinge axes of the two side panels have the same height, and one side panel will always tilt and overlap the other side panel, making it impossible for both side panels to rotate to a horizontal state at the same time. To this end, a sliding channel that can move up and down can be provided in the hinge groove, so that the hinge axis can move up and down in the sliding channel to change the height of the hinge axis. In this case, when the two side panels are folded toward each other, the height of the hinge axes of the two side panels can be changed up and down, so that both side panels can be rotated to a horizontal state. However, the fact that the hinge axis can move up and down makes the position of the side panels unstable in the height direction. For example, when transporting a folding basket filled with goods, the side panels of the folding basket are all in a vertical state. When transporting the folding basket, the side panels will be grasped and then lifted up. At this time, the upward movement of the side panels will seriously affect the transport operation. Therefore, after providing a slide that slides up and down in the hinge hole or hinge groove, there is a problem that the side panels will move up and down when the folding basket is used, affecting the transport operation. Utility Model Content

[0004] The utility model provides a side plate and a turnover basket, which are used to solve the problem that after a slideway for sliding up and down is provided in a hinge groove, the side plate will move up and down when the foldable basket is used, thereby affecting the carrying operation.

[0005] The technical solution of the utility model is as follows:

[0006] A side plate is provided with a second connecting portion, wherein the second connecting portion comprises a rotating shaft extending toward the side of the side plate and a load-bearing block, wherein the load-bearing block is located between the rotating shaft and the body of the side plate.

[0007] In this solution, the rotating shaft can be rotatably connected to the hinge groove on the base and can move up and down along the hinge groove. The load-bearing block is located between the rotating shaft and the body of the side panel. That is, when the side panel is in a vertical state, the load-bearing block is located on the upper side of the rotating shaft. At this time, the load-bearing block can abut against the top of the hinge groove. When the load-bearing block abuts against the top of the hinge groove, the hinge shaft cannot move upward, so that the side panel will not move up and down in the vertical state. That is, when the folding basket is in use, the side panel is stably connected to the base, solving the problem of the side panel moving up and down when the folding basket is in use. After the side panel rotates, the load-bearing block will leave the hinge groove, allowing the rotating shaft to move up and down, so that the rotating shafts of the two opposite side panels can move to different heights, so that the two opposite side panels can be rotated to a horizontal state, so that the top of the folding basket is flat after folding, which is convenient for stacking multiple folding baskets up and down.

[0008] In order to solve the problem of unstable connection between the side plate and the base, the second connection portion is provided with two load-bearing blocks, and the two load-bearing blocks extend to two side surfaces of the side plate respectively.

[0009] In this solution, two load-bearing blocks are provided on the second connection part, and the two positioning axes extend to the two sides of the side plate respectively. Therefore, when the load-bearing blocks are connected to the bottom plate, the forces on both sides of the second connection part are more evenly distributed, thereby making the connection between the second connection part and the base more stable.

[0010] In order to solve the problem of unstable connection between the side panel and the base, the side panel is provided with at least two second connection parts.

[0011] In this solution, the side panel is provided with at least two second connection parts. The more second connection parts are provided on the side panel, the more connection points there are with the base, which can improve the stability of the connection between the side panel and the bottom panel.

[0012] In order to solve the problem of uneven movement of the bearing block when the side plate rotates, the bearing block is provided with a first guide surface, and when the side plate is in a vertical state, the first guide surface is provided at the junction of the top surface and a side surface of the bearing block.

[0013] In this solution, the first guide surface can guide the movement of the load-bearing block to avoid interference between the load-bearing block and the base during movement, and to prevent the load-bearing block from getting stuck and causing the side panel to be unable to rotate.

[0014] Preferably, the second connecting portion includes two rotation shafts, and the two rotation shafts extend to two side surfaces of the side plate respectively.

[0015] In this solution, the second connecting part is provided with two rotation axes, and the two positioning axes can make the second connecting part bear the force more evenly, thereby improving the stability of the connection between the second connecting part and the base.

[0016] Preferably, a second guide surface is provided at the bottom of the second connecting portion.

[0017] In this solution, the second connecting portion is provided with a second guide surface, which can prevent the rotating shaft from interfering with the base during rotation, and prevent the rotating shaft from getting stuck and causing the side plate to be unable to rotate.

[0018] In order to solve the problem of the side plate moving along the side direction, the side plate is further provided with a positioning boss, and the positioning boss is arranged on the bottom surface of the side plate.

[0019] In this solution, a positioning boss is provided on the bottom surface of the side panel, and the side surface of the positioning boss can abut against the base from the side, thereby preventing the side panel from moving sideways.

[0020] The utility model also provides a turnover basket, including the above-mentioned side panels and a base, the base is provided with a hinge groove, the hinge groove is provided with a sliding opening, the sliding opening is provided on a side close to the base, the rotating shaft is rotatably connected to the hinge groove, a positioning structure is provided at the top of the hinge groove, the bottom surface of the side panel abuts against the base, and the top of the load-bearing block abuts against the positioning structure.

[0021] In this solution, the side panels are rotatably connected to the base, so that the turnover basket can be folded. Moreover, when the side panels are in a vertical state, the top of the load-bearing block abuts against the positioning structure, thereby fixing the side panels in the height direction, solving the problem of the side panels moving up and down when the folding frame is in use.

[0022] Preferably, the top of the hinge slot passes through the base, and there is a gap between the hinge slot and the positioning structure to accommodate the upward and downward movement of the rotating shaft. The rotating shaft can be inserted downward from the hinge slot into the hinge slot, making it easier to install the side panel on the base. During installation, it is only necessary to move the side panel downward in an inclined or horizontal state so that the rotating shaft is engaged with the hinge slot. When the rotating shaft moves to the lower side of the positioning structure, the side panel is rotated upward to engage the load-bearing block with the lower side of the positioning structure.

[0023] Preferably, the rotation axis is provided with a fitting surface, the fitting surface is parallel to the side plate where the rotation axis of the side plate is located, and the fitting surface is adjacent to the inner side surface of the hinge groove.

[0024] In this solution, the fitting surface fits in with the inner side surface of the hinge groove, so that when the rotating shaft needs to rotate, the side plate can maintain its relative position with the base.

[0025] Beneficial effects of the utility model:

[0026] When the side panels of the present invention are in a vertical state, the load-bearing blocks are located on the upper side of the rotating shaft. At this time, the load-bearing blocks can abut against the top of the hinge groove. When the load-bearing blocks abut against the top of the hinge groove, the hinge shaft cannot move upward, so that the side panels will not move up and down in the vertical state. That is, when the folding basket is in use, the side panels are stably connected to the base, which solves the problem that the side panels will move up and down when the folding frame is in use.

[0036] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely explained through the specific implementation methods of the embodiments of the present invention.

[0037] Example 1:

[0038] like Figure 1As shown, this embodiment provides a side panel, wherein the bottom of the side panel 1 is provided with a second connecting portion 4, wherein, when the side panel 1 is in a vertical state, the second connecting portion 4 is used to connect with the base, and the second connecting portion 4 is provided with a rotating shaft 42, so that the side panel 1 can be rotatably connected with the base. Figure 2 and Figure 3 As shown, the second connection portion 4 is further provided with a load-bearing block 3, which is located between the main body of the side panel 1 and the rotation axis 42, wherein one end of the load-bearing block 3 is connected to the side surface of the second connection portion 4. The axis of the load-bearing block 3 is parallel to the plate surface of the side panel 1, so that after the side panel 1 is connected to the base, the side panel 1 can rotate around the axis of the load-bearing block 3.

[0039] Load-bearing blocks 3 are respectively provided on both sides of the second connecting part 4. The top surfaces of the load-bearing blocks 3 on both sides of the second connecting part 4 are flush, so that the tops of the two load-bearing blocks 3 can be against the hinge grooves on the base, so that the two load-bearing blocks 3 can jointly bear the force between the side panel and the base.

[0040] The lengths of the load-bearing blocks 3 can be the same, or the lengths of the load-bearing blocks 3 can be different.

[0041] A plane is provided on the top of the load-bearing block 3 to increase the connection area between the load-bearing block 3 and the base.

[0042] The load-bearing block 3 can be a block structure with a polygonal cross section, or a rod structure.

[0043] When the side panel 1 rotates, the load-bearing block 3 rotates relative to the base. The load-bearing block 3 is provided with a first guide surface 31 , which is located at the junction of the top of the load-bearing block 3 and one side surface of the load-bearing block 3 .

[0044] The first guide surface 31 is an arc-shaped surface or an inclined plane, the purpose of which is to eliminate the corner between the top surface and the side surface so that the bearing block 3 can rotate more smoothly.

[0045] A positioning boss 2 can also be provided at the bottom of the side panel 1. The positioning boss 2 is used to constrain the position of the side panel 1 from the left and right sides of the side panel 1 to prevent the side panel 1 from moving left or right. The positioning boss 2 can prevent the base from exerting force in the axial direction on the load-bearing block 3, thereby preventing the load-bearing block 3 from being damaged by the axial force.

[0046] The positioning bosses 2 can be provided on both sides of the bottom of the side panel 1 and respectively abut against the base from both sides.

[0047] The positioning boss 2 can also be set at the middle position of the bottom of the side panel 1. In this case, a positioning groove needs to be set at the corresponding position of the base so that the positioning boss 2 can be snapped into the positioning groove.

[0048] like Figure 2 and Figure 3 As shown, in another embodiment, the side panel 1 further includes a second connecting portion 4 .

[0049] The second connecting portion 4 further includes a second positioning block 41. A rotation shaft 42 and the load-bearing block 3 are respectively connected to the side surfaces of the second positioning block 41. The axis of the rotation shaft 42 is parallel to the axis of the load-bearing block 3. When the side panel 1 is in the vertical state, the height of the rotation shaft 42 is lower than that of the load-bearing block 3, that is, the load-bearing block 3 is located above the rotation shaft.

[0050] The hinge groove 5 is provided with a sliding channel for the rotating shaft 42 in the vertical direction, so that the rotating shaft 42 can be installed in the hinge groove 5 and can slide up and down in the hinge groove 5.

[0051] A plurality of second positioning blocks 41 may be provided at the bottom of the side panel 1 .

[0052] like Figure 4 As shown, the rotating shaft 42 is located at the bottom of the second connecting portion 4. The rotating shaft 42 is provided with a second guide surface 43. The second guide surface 43 is provided at the intersection of the bottom and the side of the rotating shaft 42 to eliminate the corner between the bottom and the side of the rotating shaft 42, so that the rotating shaft 42 can rotate more smoothly. The second guide surface 43 and the first guide surface 31 are located on the same side of the side plate 1.

[0053] The second guide surface 43 may be an arcuate surface or an inclined plane.

[0054] Example 2:

[0055] The second embodiment provides a turnover basket, including the side panels 1 described in the first embodiment.

[0056] The turnover basket also includes a base, which includes a bottom plate and a mounting plate arranged on the edge of the bottom plate.

[0057] like Figure 5 and Figure 6 As shown, the mounting plate is provided with a vertical hinge slot 5, which is provided with a sliding opening 7. The sliding opening 7 is located on one side near the center of the base and is wider than the width of the second positioning block 41. The top of the sliding opening 7 is required to accommodate the load-bearing block 3, while the bottom of the sliding opening 7 only accommodates the second connecting block 41. The sliding opening 7 is T-shaped. When the rotating shaft 42 moves up and down within the hinge slot 5, the second positioning block 41 can move up and down along the sliding opening 7.

[0058] A first guide surface 31 is provided on the top of the load-bearing block 3. The first guide surface 31 can prevent the top of the load-bearing block 3 from interfering with the positioning structure 6 during the rotation of the side panel 1. An inclined surface is also provided on the bottom of the load-bearing block 3. The function of the inclined surface is to prevent the bottom of the load-bearing block 3 from interfering with the T-shaped sliding opening 7 during the rotation of the side panel 1.

[0059] The top of the hinge slot 5 passes through the base, and a positioning structure 6 is provided in the hinge slot 5. The positioning structure 6 is used to cooperate with the load-bearing block 3. When the side panel is connected to the base and the side panel is in a vertical position, the top of the load-bearing block 3 abuts the bottom of the positioning structure 6, and the bottom surface of the side panel abuts the base. Therefore, the side panel cannot move up and down, and the relative position of the side panel and the base is fixed. When the side panel is vertical, the folding frame can also be placed with goods. During the transportation of the folding frame, the side panel will not move up and down relative to the base.

[0060] It should be noted that the positioning structure 6 is located on the side where the sliding opening 7 is located, that is, on the side close to the center of the base. There is a gap between the positioning structure 6 and a vertical surface of the hinge groove 5 away from the center of the base. The width of this gap in the horizontal direction is greater than the diameter of the rotation axis 42, which allows the rotation axis 42 to pass through in the vertical direction. Therefore, during installation, the side panel 1 is tilted or horizontally adjusted so that the rotation axis 42 enters the hinge groove 5 from top to bottom. When the rotation axis 42 moves to the bottom side of the positioning structure 6, the side panel can be rotated so that the load-bearing block 3 can be snapped into the bottom side of the positioning structure 6.

[0061] The second guide surface 43 provided on the second connecting portion 4 can prevent the second connecting portion 4 from abutting against the hinge groove 5 and thus becoming immobile. The second guide surface 43 can reduce the size of the second connecting portion 4 and facilitate the installation of the second guide portion 4.

[0062] The positioning structure 6 can be a block structure arranged in the hinge groove 5 , and the block structure is arranged on the inner side wall of the hinge groove 5 .

[0063] The positioning structure 6 can also be a sealing plate provided on the top of the hinge groove 5 , and the sealing plate blocks the top of the hinge groove 5 .

[0064] After the load-bearing block 3 rotates from the horizontal direction to leave the hinge groove 5, the rotation axis 42 can move up and down along the hinge groove 5. When the side panels are folded, no matter which side panel is folded toward the base first, the two opposite side panels can be rotated to a horizontal state, so that the top of the turnover basket remains horizontal after folding, which facilitates the rapid stacking and palletizing of multiple turnover baskets.

[0065] The rotating shaft 42 is provided with a contact surface 44 that is parallel to the side panel. It should be noted that the contact surface 44 being parallel to the side panel means being parallel to the largest plane of the side panel. In other words, when the side panel is in a vertical position, the contact surface 44 is parallel to the vertical plane, and in this case, the contact surface 44 is located on the side closest to the center of the base. When the side panel is in the vertical position, the contact surface 44 contacts the inner side surface of the hinge groove 5. At this time, if the side panel is to rotate toward the center of the base, the contact surface 44 needs to be separated from the inner side surface of the hinge groove 5. The contact surface 44 and the inner side surface of the hinge groove 5 provide a certain resistance. Therefore, the contact surface 44 and the inner side surface of the hinge groove 5 help the side panel maintain its vertical position. When the folding basket is to be used, the side panel needs to be rotated to a vertical position first, and then connected to the other side panels to allow the folding basket to place goods. During this process, the contact surface 44 and the inner side surface of the hinge groove 5 help the side panel maintain its vertical position, making it easier to operate. The connection between the side panels can refer to the side panel connection method of the folding basket in the prior art.

[0066] The mounting plate is provided with a positioning groove, the position and shape of which correspond to the positioning boss 2 of the bottom plate of the side plate 1 , and the positioning boss 2 can be snapped into the positioning groove.
