Description

Technical Field

[0001] This utility model relates to the field of material feeding frame production technology, and in particular to a folding material feeding frame. Background Technology

[0002] Material crates (also known as storage crates or material handling crates) are commonly used turnover containers in industrial production, agricultural production, and logistics warehousing. They are mainly used for the storage, transportation, and turnover of materials, and can also be used to store tools or products. Material crates generally consist of a base plate and side plates surrounding each side of the base plate. To make full use of the space in production workshops or logistics parks, the side plates of the material crates are generally set vertically so that multiple material crates can be placed closely side by side to save space in the production workshop or logistics park. However, the vertical setting of the side plates of the material crates prevents the material crates from being nested and stacked, resulting in empty material crates occupying a lot of space when stored. To address the above issues, Chinese patent CN201864119U discloses a foldable material feeding frame, which solves the problem of excessive space occupation when the material frames are stacked and realizes a foldable design. However, this product still has shortcomings. After being deformed and assembled into a usable material frame, the left and right side plates are only connected to the bottom plate by snap-fit, which has low connection strength. During the use of the material frame, the snap-fit ​​structure is prone to detachment due to collisions, drops, vibrations, etc., resulting in the material frame becoming loose and causing the assembly state of the material frame to fail. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a folding frame, which has a more reliable structure in the assembled state and is less prone to loosening and deformation.

[0004] A folding frame according to an embodiment of the present utility model includes:

[0005] The frame includes a fixed frame, multiple folding side panels, multiple flipping side panels, and a bottom plate, with the multiple folding side panels and multiple flipping side panels disposed between the fixed frame and the bottom plate;

[0006] The locking mechanism includes a lock hole provided in the flip side panel, a lock groove and a lock block provided in the base plate. The lock block can pass through the lock hole and abut against the lock groove to lock the relative position between the base plate and the flip side panel.

[0007] A folding frame according to an embodiment of the present utility model has at least the following beneficial effects:

[0008] When the bottom of the flip-up side panel is flipped to the edge of the base plate, the flip-up side panel is in a vertical position. At this time, the locking mechanism locks the relative position between the base plate and the flip-up side panel, preventing the flip-up side panel from moving relative to the base plate or the fixed frame. The locking block in the locking mechanism limits the lock hole on the flip-up side panel to the lock groove on the base plate, greatly improving the reliability of the connection between the flip-up side panel and the base plate. This reduces the risk of the connection separating from the base plate due to collisions, drops, vibrations, etc., and reduces the possibility of the folding frame becoming loose and deformed. The folding frame has a stable and reliable structure in the assembled state, improving the reliability of the folding frame during material storage, transportation, and turnover, reducing the possibility of material spillage, scratches, or even damage, and achieving better material storage functionality. The reliable folding frame structure allows the frame to be folded when not in use, solving the problem of excessive space occupation when stacking frames for storage, saving space in production workshops or storage warehouses, and making it easier to organize and store compared to ordinary non-foldable frames.

[0009] According to an embodiment of the present invention, a folding frame is provided between the lock hole and the lock block, and the lock assembly is used to limit the relative position of the lock block and the lock hole.

[0010] The benefits include: preventing the lock block from sliding out of the keyhole and improving the reliability of the connection between the keyhole, lock groove and lock block.

[0011] According to an embodiment of the present utility model, a folding frame includes a latching portion disposed on the wall of the lock hole and a protruding latching portion disposed on one side of the lock block; or, the locking frame includes a protruding latching portion disposed on the wall of the lock hole and a latching portion disposed on one side of the lock block, wherein the latching portion and the protruding latching portion are matingly connected.

[0012] The advantages are: it facilitates the insertion and disengagement of the lock block from the lock hole, thus improving the reliability of the locking mechanism.

[0013] According to an embodiment of the present invention, a folding frame has elastic portions on opposite sides of the locking block.

[0014] The advantages are: the elastic force of the elastic part generates a squeezing force on the inner wall of the key hole, which further prevents the lock block from sliding out of the key hole. Moreover, when the protruding part is disengaged from the buckle, the elastic part can also limit the relative position of the lock block to a certain extent, so as to prevent the protruding part from sliding back into the buckle during operation.

[0015] According to an embodiment of the present utility model, a folding frame includes a first plate and a second plate, which are hinged together. The top edge of the first plate is hinged to a fixed frame, and the bottom edge of the second plate is hinged to a bottom plate.

[0016] The benefits are: improved stability when the shape of the folding frame changes, and improved overall stability of the folding frame.

[0017] According to an embodiment of the present utility model, a folding frame is provided between a first plate and a second plate. The first hinge mechanism includes a first rotating shaft disposed on the first plate and a first bushing disposed on the second plate; or, the first hinge mechanism includes a first bushing disposed on the first plate and a first rotating shaft disposed on the second plate, wherein the first bushing is an open bushing.

[0018] The advantage is that it facilitates the first rotating shaft to be pressed into the first bushing from the opening side, thereby improving the manufacturing efficiency of the folding frame.

[0019] According to an embodiment of the present utility model, a folding frame is provided between a first plate and a second plate. The second hinge mechanism includes a second rotating shaft, a second bushing disposed on the first plate, and a third bushing disposed on the second plate. The second rotating shaft can pass through the second bushing and the third bushing and is restricted to move axially along the second bushing.

[0020] The advantage is that it prevents the second pivot from detaching from the second or third bushing, thus improving the reliability of the hinge between the first and second plates.

[0021] According to an embodiment of the present invention, a folding frame has a second rotating shaft that is a self-locking rotating shaft.

[0022] The advantage is that by simply pressing the second rotating shaft into the second and third bushings, the axial movement of the second rotating shaft along the second bushing can be restricted, thus improving the manufacturing convenience of the folding frame.

[0023] According to an embodiment of the present utility model, a folding material frame is provided with multiple limiting buckles on the side edge of the folding side plate and multiple limiting grooves on the side edge of the flipping side plate. The multiple limiting buckles and multiple limiting grooves correspond one-to-one and can be matched and connected.

[0024] The advantages are: it can limit the flipping stroke of the flipping side plate, preventing the flipping side plate from flipping to the outside of the base plate, and at the same time, it is convenient to position the bottom side of the flipping side plate when it flips to the edge of the base plate, so that the locking block of the locking mechanism can be more easily inserted and abutted into the locking groove.

[0026] The advantage is that when the bottom of the flip side panel is flipped to the edge of the base plate, the connecting pin can be engaged in the connecting buckle, which improves the connection reliability between the flip side panel and the base plate. At the same time, it further facilitates the positioning of the bottom of the flip side panel and the edge of the base plate so that the locking mechanism can perform the locking operation.

[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] In the description of a utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0044] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0045] Reference Figures 1 to 6 This utility model provides a folding material frame, including a frame body and a locking mechanism 500. The frame body includes a fixed frame 100, multiple folding side plates 200, multiple flipping side plates 300, and a bottom plate 400. The multiple folding side plates 200 and multiple flipping side plates 300 are disposed between the fixed frame 100 and the bottom plate 400. The locking mechanism 500 includes a lock hole 510 disposed in the flipping side plate 300, a lock groove 520 disposed in the bottom plate 400, and a lock block 530. The lock block 530 can pass through the lock hole 510 and abut against the lock groove 520 to lock the relative position between the bottom plate 400 and the flipping side plate 300.

[0046] Specifically, the upper ends of the multiple folding side panels 200 are hinged to the bottom edge of the fixed frame 100, and the folding side panels 200 can rotate relative to the fixed frame 100. The lower ends of the multiple folding side panels 200 are hinged to the upper edge of the base plate 400, and the folding side panels 200 can also be folded to reduce the height of the folding side panels 200. The upper sides of the multiple flipping side panels 300 are hinged to the bottom edge of the fixed frame 100, and the flipping side panels 300 can rotate relative to the fixed frame 100 so that the flipping side panels 300 can flip and switch between vertical and horizontal states.

[0047] Specifically, multiple flip-up side panels 300 and multiple folding side panels 200 are staggered along the circumference of the fixed frame 100 so that the multiple flip-up side panels 300 are evenly spaced between the fixed frame 100 and the base plate 400. When the flip-up side panels 300 are in a vertical state, the folding side panels 200 are also in an extended state. At this time, the staggered flip-up side panels 300 and folding side panels 200 enclose the space between the fixed frame 100 and the base plate 400 to form an assembled folding frame.

[0048] Specifically, since multiple flip side panels 300 and multiple folding side panels 200 are staggered along the circumference of the fixed frame 100, the multiple flip side panels 300 are evenly spaced between the fixed frame 100 and the base plate 400. In the assembled state, since each flip side panel 300 has folding side panels 200 on both sides, the included angle between adjacent folding side panels 200 and flip side panels 300 cannot be 0 degrees or 180 degrees. When the fixed frame 100 and the base plate 400 tend to move in a direction perpendicular to the flip side panels 300 (i.e., the thickness direction of the flip side panels 300), the adjacent folding side panels 200 can provide a reverse force to resist the movement. Therefore, the fixed frame 100 and the base plate 400 cannot move relative to each other in a direction perpendicular to the flip side panels 300. The locking mechanism 500 restricts the flip side panels 300 to only be in a vertical state, so the base plate 400 cannot move along the flip side panels. The plate 300 moves towards the fixed frame 100 in the height direction; since the upper end of the folding side plate 200 is hinged to the bottom edge of the fixed frame 100 and the lower end of the folding side plate 200 is hinged to the upper edge of the base plate 400, the base plate 400 cannot move away from the fixed frame 100 in the height direction of the folding side plate 300; since the upper sides of the multiple folding side plates 300 are hinged to the bottom edge of the fixed frame 100, and the locking mechanism 500 locks the lower side of the folding side plate 300 and the base plate 400, the fixed frame 100 and the base plate 400 cannot move relative to each other in the length direction of the folding side plate 300; in summary, the folding frame in the assembled state has sufficient structural strength.

[0049] As a preferred option, refer to Figure 1The fixed frame 100 is a rectangular structure, with adjacent sides of the fixed frame 100 perpendicular to each other. The base plate 400 is a rectangular plate structure, with adjacent sides of the base plate 400 also perpendicular to each other. There are two folding side plates 200 and two flipping side plates 300. The folding side plates 200 and flipping side plates 300 are staggered and hinged to the bottom edges of the four sides of the fixed frame 100. Simultaneously, the folding side plates 200 and flipping side plates 300 are staggered and positioned at the top edges of the four sides of the base plate 400. That is, referring to... Figure 1 and Figure 2 Two folding side panels 200 are arranged opposite each other, and two flipping side panels 300 are also arranged opposite each other. The arrangement direction between the two folding side panels 200 and the arrangement direction between the two flipping side panels 300 are perpendicular to each other. Specifically, adjacent folding side panels 200 and flipping side panels 300 are also perpendicular to each other.

[0050] As a preferred option, the flip-up side panel 300 can be flipped to the inside of the fixed frame 100 to reduce the space occupied.

[0051] Because a locking mechanism 500 is provided between the base plate 400 and the flip side plate 300, when the bottom side of the flip side plate 300 is flipped to the edge of the base plate 400, the flip side plate 300 is in a vertical state. At this time, the locking mechanism 500 locks the relative position between the base plate 400 and the flip side plate 300, preventing the flip side plate 300 from moving relative to the base plate 400. The locking block 530 in the locking mechanism 500 can limit the locking hole 510 on the flip side plate 300 and the locking groove 520 on the base plate 400, greatly improving the connection reliability between the flip side plate 300 and the base plate 400, reducing the possibility of the connection between the flip side plate 300 and the base plate 400 being detached due to collisions, drops, vibrations, etc., and reducing the possibility of the folding frame becoming loose and deformed. The structure of the folding frame in the assembled state is stable and reliable, improving the reliability of the folding frame in the storage, transportation and turnover of materials, reducing the possibility of materials scattering, scratching or even being damaged, and realizing a better function of the frame for storing materials. A reliable folding frame structure is achieved, which can be folded when not in use, solving the problem of excessive space occupation when frames are stacked and stored, saving space in production workshops or storage warehouses, and making it easier to organize and store compared to non-foldable frames.

[0052] It is understood that in some other embodiments, the folding side panel 200, the flipping side panel 300, and the bottom plate 400 are all perforated plates to reduce the overall weight of the folding frame.

[0053] According to some embodiments of this application, refer to Figure 3 and Figure 4A latch assembly is provided between the lock hole 510 and the lock block 530. The latch assembly is used to limit the relative position of the lock block 530 and the lock hole 510 to prevent the lock block 530 from sliding out of the lock hole 510 and improve the connection reliability between the lock hole 510, the lock groove 520 and the lock block 530.

[0054] Furthermore, the locking assembly includes a latch portion 511 disposed on the wall of the lock hole 510 and a protruding latch portion 531 disposed on one side of the locking block 530. The latch portion 511 and the protruding latch portion 531 can be matched and connected. Specifically, when the locking block 530 is fully inserted into the lock hole 510 and abuts against the lock groove 520, the protruding latch portion 531 slides into the latch portion 511 and is limited by the latch portion 511, thereby locking the flip side plate 300 and the bottom plate 400. After pressing the protruding latch portion 531 and disengaging it from the latch portion 511, the locking block 530 can be pulled out from the lock hole 510 to release the lock between the flip side plate 300 and the bottom plate 400, so as to convert the folding frame from the assembled state to the folded state.

[0055] It is understood that, in some other embodiments, reference is made to... Figure 4 The latch assembly includes a protruding latch portion 531 disposed on the wall of the lock hole 510 and a latching opening portion 511 disposed on one side of the lock block 530. The latching opening portion 511 and the protruding latch portion 531 can be matched and connected, and can also achieve the function of preventing the lock block 530 from sliding out of the lock hole 510.

[0056] It is understood that in some other embodiments, the latch assembly may include a screw hole provided in the wall of the lock hole 510, a screw hole provided on one side of the lock block 530, and a bolt. The bolt passes through the screw hole in the wall of the lock hole 510 and the screw hole in the lock block 530 to connect the lock hole 510 and the lock block 530, and at the same time, it can prevent the lock block 530 from sliding out of the lock hole 510.

[0057] Furthermore, referring to Figure 4 The locking block 530 has elastic portions 532 on opposite sides. Specifically, the elastic portion 532 is a member protruding from the side of the locking block 530. When this protruding member is squeezed and deformed, it generates elastic force. The elastic force of the elastic portion 532 generates a squeezing force on the inner wall of the lock hole 510, further preventing the locking block 530 from sliding out of the lock hole 510. Moreover, when the protruding buckle 531 is disengaged from the buckle opening 511, the elastic portion 532 can also limit the relative position of the locking block 530 to a certain extent, so as to prevent the protruding buckle 531 from sliding back into the buckle opening 511 during operation, thereby improving the convenience of pulling the locking block 530 out of the lock hole 510.

[0058] According to some embodiments of this application, refer to Figure 5The folding side panel 200 includes a first plate 210 and a second plate 220, which are hinged together. The top edge of the first plate 210 is hinged to the fixed frame 100, and the bottom edge of the second plate 220 is hinged to the base plate 400. The fixed frame 100, the first plate 210, the second plate 220, and the base plate 400 are sequentially hinged. Whether the folding frame is in its assembled or folded state, the fixed frame 100, the first plate 210, the second plate 220, and the base plate 400 are always connected, which improves the stability of the folding frame when its shape changes, and also improves the overall stability of the folding frame.

[0059] Furthermore, a first hinge mechanism 230 is provided between the first plate 210 and the second plate 220. The first hinge mechanism 230 includes a first rotating shaft 231 disposed on the first plate 210 and a first bushing 232 disposed on the second plate 220. The first bushing 232 is an open bushing. This facilitates the first rotating shaft 231 being pressed into the first bushing 232 from the open side, thereby improving the manufacturing efficiency of the folding frame.

[0060] It is understood that in some other embodiments, the first hinge mechanism 230 includes a first bushing 232 disposed on the first plate 210 and a first rotating shaft 231 disposed on the second plate 220. The first bushing 232 is an open bushing, which can also realize the hinge between the first plate 210 and the second plate 220, and also has the effect of easy connection.

[0061] Furthermore, a second hinge mechanism 240 is provided between the first plate 210 and the second plate 220. The second hinge mechanism 240 includes a second rotating shaft 243, a second bushing 241 disposed on the first plate 210, and a third bushing 242 disposed on the second plate 220. The second rotating shaft 243 can pass through the second bushing 241 and the third bushing 242 and is restricted to move axially along the second bushing 241. By utilizing the second rotating shaft 243, the second bushing 241, and the third bushing 242, a hinge is achieved between the first plate 210 and the second plate 220. At the same time, since the second rotating shaft 243 is restricted to move axially along the second bushing 241, the second rotating shaft 243 is prevented from disengaging from the second bushing 241 or the third bushing 242, thus improving the reliability of the hinge.

[0062] Furthermore, the second rotating shaft 243 is a self-locking rotating shaft. By simply pressing the second rotating shaft 243 into the second bushing 241 and the third bushing 242, the axial movement of the second rotating shaft 243 along the second bushing 241 can be restricted, thereby improving the manufacturing convenience of the folding frame.

[0063] It is understood that in some other embodiments, the second rotating shaft 243 is a shaft bolt used in conjunction with a counter nut, which can also achieve the effect of the second bushing 241 and the third bushing 242 rotating around the second rotating shaft 243, and restricting the axial movement of the second rotating shaft 243 along the second bushing 241.

[0064] It is understood that, in some other embodiments, reference is made to... Figure 5 The first plate 210 has a first protrusion 211 on the side near the second plate 220, and the second plate 220 has a second recess 222 on the side near the first plate 210. The first protrusion 211 and the second recess 222 can be matched and connected to limit the rotation angle between the first plate 210 and the second plate 220, so that the first plate 210 and the second plate 220 can rotate to a maximum of parallel to each other, and prevent the first plate 210 and the second plate 220 from folding outward.

[0065] It is understood that in some other embodiments, the second plate 220 is provided with a second protrusion 221 on the side near the first plate 210, and the first plate 210 is provided with a first recess 212 on the side near the second plate 220. The second protrusion 221 and the first recess 212 can be matched and connected to further limit the rotation angle between the first plate 210 and the second plate 220.

[0066] According to some embodiments of this application, refer to Figure 2 The folding side panel 200 has multiple limiting buckles 250 on its side edge, and the flipping side panel 300 has multiple limiting grooves 310 on its side edge. The multiple limiting buckles 250 and the multiple limiting grooves 310 are matched and connected one-to-one. By using the limiting buckles 250 and the limiting grooves 310 to cooperate, the flipping stroke of the flipping side panel 300 can be limited, preventing the flipping side panel 300 from flipping to the outside of the base plate 400. At the same time, it is convenient to position the bottom side of the flipping side panel 300 when it flips to the edge of the base plate 400, so that the locking block 530 of the locking mechanism 500 can be more easily inserted and abutted into the locking groove 520.

[0067] According to some embodiments of this application, refer to Figure 3 and Figure 4 The bottom of the flip-up side panel 300 is provided with multiple connecting pins 320, and the top surface of the base plate 400 is provided with multiple connecting buckles 410 corresponding to the multiple connecting pins 320. The connecting pins 320 and the connecting buckles 410 can be matched and connected. By using the cooperation of the connecting pins 320 and the connecting buckles 410, when the bottom side of the flip-up side panel 300 is flipped to the edge position of the base plate 400, the connecting pins 320 can be fastened in the connecting buckles 410, which improves the connection reliability between the flip-up side panel 300 and the base plate 400, and at the same time further facilitates the positioning of the bottom side of the flip-up side panel 300 and the edge position of the base plate 400 so that the locking mechanism 500 can perform the locking operation.

[0068] It is understood that, in some other embodiments, reference is made to... Figure 3 A limiting wall 420 is provided above the circumferential side of the base plate 400 to further limit the movement of the flip side plate 300 and the second plate 220, prevent the flip side plate 300 and the second plate 220 from rotating to the outside of the base plate 400, and at the same time improve the firmness of the folding frame in the assembled state.

[0069] It is understood that, in some other embodiments, reference is made to... Figure 1 and Figure 2 The top of the flip side panel 300 is provided with a third protrusion 330, and the bottom of the fixed frame 100 is provided with a corresponding third recess 110. The third protrusion 330 and the third recess 110 can be connected to each other so that after the flip side panel 300 is flipped to the vertical state, the third protrusion 330 and the third recess 110 cooperate to restrict the movement of the flip side panel 300 relative to the fixed frame 100, thereby improving the structural reliability of the folding frame. Moreover, the third recess 110 provided on the fixed frame 100 can also act as a handle in the folded state, so as to quickly change the folding frame from the folded state to the assembled state.

[0070] It is understood that, in some other embodiments, reference is made to... Figure 3 and Figure 4 The bottom of the flip side plate 300 is also provided with a plurality of fourth protrusions 340, and the top surface of the bottom plate 400 is provided with a plurality of fourth recesses 430. The plurality of fourth protrusions 340 and the plurality of fourth recesses 430 can be connected one by one, so that after the flip side plate 300 is connected to the bottom plate 400, the movement of the flip side plate 300 relative to the bottom plate 400 is further restricted, and the structural reliability of the folding frame is further improved.

[0071] Working principle: When transitioning from a folded state to an assembled state, the fixing frame 100 is first moved away from the base plate 400, increasing the relative distance between the fixing frame 100 and the base plate 400. At this time, the folding side panel 200 gradually changes to an extended state under the pulling force from the upper and lower sides. Then, the flipping side panel 300 flips from a horizontal to a vertical position within the fixing frame 100, so that the bottom side of the flipping side panel 300 flips to the edge of the base plate 400. The locking mechanism 500 then locks the base plate 400 and the flipping side panel 300 to restrict the movement of the flipping side panel 300 relative to the base plate 400. When the flipping side panel 300 is locked by the locking mechanism 500... When the base plate 400 is fixed, the flip side plate 300 is in a vertical state. Since the flip side plate 300 and the folding side plate 200 are arranged alternately, and the upper and lower ends of the folding side plate 200 are respectively hinged to the fixed frame 100 and the base plate 400, the folding side plate 200 can restrict the fixed frame 100 and the base plate 400 from moving in a direction perpendicular to the flip side plate 300. At the same time, by using the upper part of the flip side plate 300 to hinge to the fixed frame 100 and the lower part of the flip side plate 300 to lock the base plate 400 through the locking mechanism 500, the movement of the fixed frame 100 and the base plate 400 can be restricted in a direction parallel to the flip side plate 300, thereby realizing the fixed connection between the components of the folding frame and forming an assembled state.

[0072] When it is necessary to change from the assembled state to the folded state, simply pull the locking block 530 out of the locking hole 510 and the locking groove 520 to release the locking connection between the flip side plate 300 and the bottom plate 400, and then flip the flip side plate 300 to the horizontal state. During this process, the folding side plate 200 is folded at the same time, so that the folding frame can be changed to the folded state.
