[0009] When the sliding end is in the first position, the baffle is locked to the frame;

[0010] When the sliding end is in the second position, the baffle separates from the frame.

[0011] Optionally, the baffle is detachably mounted on the mounting side.

[0012] Optionally, the support component includes:

[0013] A support rod, one end of which is the rotating end and the other end of which is the sliding end; and

[0014] A slider is provided on the support side, and a groove is provided on the slider or the support side. The sliding end is provided with a slider that matches the groove.

[0015] Optionally, the slide groove includes a disassembly end, a connecting part, and a snap-fit ​​end connected in sequence;

[0016] The slider has a slide rod and a limiting block located on the side of the slide rod opposite to the support rod.

[0017] The diameter of the limiting block is larger than the diameter of the sliding rod, and also larger than the width of the connecting part and the width of the snap-fit ​​end;

[0018] The diameter of the disassembly end is larger than the diameter of the limiting block, and the width of the connecting part is larger than the diameter of the slide rod;

[0019] The snap-fit ​​end has a downward snap-fit ​​groove that can accommodate the slide rod.

[0020] Optionally, the snap-fit ​​groove is inclined downward toward the disassembly end, away from the groove wall of the disassembly end.

[0021] Optionally, the support component further includes:

[0022] A locking assembly is installed on the side frame on the side of the baffle, and the distance between the axis of the locking assembly and the axis of the rotating end is the same as the distance between the axis of the limiting block and the axis of the rotating end.

[0023] The limiting block has a lock hole in the center that matches the locking group.

[0024] Optionally, the locking group includes:

[0025] A knob is located on the side of the side frame opposite to the support rod, and the knob has an unlocked position and a locked position;

[0026] The lock cylinder is located within the side frame, and the knob is connected to the lock cylinder; and

[0027] The locking tongue has a clearance groove on the side frame that allows the limiting block to enter, and the locking tongue is located in the clearance groove;

[0028] When the knob is in the unlocked position, the bolt is in the retracted state;

[0029] When the knob is in the locked position, the latch extends and inserts into the keyhole.

[0030] Optionally, the mounting side is provided with a mounting groove, and a hook rod is provided in the mounting groove;

[0035] The baffle is provided with at least one locking element that locks to the side of the frame.

[0036] The technical solution provided by this utility model embodiment involves setting a support component with opposing rotating and sliding ends. The sliding end is slidably disposed on the support side of the vehicle body, while the rotating end is rotatably disposed on the side of the baffle, which is rotatably disposed on the mounting side of the vehicle body. When the frame is mounted on the vehicle body, the baffle can be locked to the side of the frame to secure it firmly to the vehicle body. When it is necessary to remove the frame from the vehicle body, the baffle can also be unlocked from the frame and rotated around the mounting side of the vehicle body until it separates from the frame. At this time, the rotating end rotates, and the sliding end moves from the first position to the second position, forming a stable triangle with the support component, the vehicle body, and the frame, eliminating the need to remove the baffle from the vehicle body. Since the frame is hoisted and disassembled, the tilted baffle will not affect the disassembly of the frame. This saves time in removing or rotating the baffle from the vehicle body, saves manpower, and eliminates the need for additional space to place the baffle, thus saving space.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0048] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0051] Please refer to Figures 1-4 As shown, this application provides a material rack cart, which includes a cart body 1 and a baffle 2. The cart body 1 has two opposing mounting sides along its length and two opposing supporting sides along its width. At least one frame is mounted on the cart body 1. A set of wheels 4 is provided under the cart body 1, which allows the operator to push the cart body 1 with the frame mounted to a predetermined position. To ensure the stability of the frame mounted on the cart body 1 and prevent it from moving relative to the cart body 1 during movement, a plurality of positioning posts 11 are provided on the cart body 1. The positioning posts 11 cooperate with positioning holes at the bottom of the frame to confine the frame to the cart body 1. Since the frame is centered and has a large size and weight, if only the bottom is limited, it would be a cantilever structure. During movement, the connection between the positioning post 11 and the positioning hole is likely to be damaged due to inertia. Therefore, baffles 2 are provided on both mounting sides of the frame. The bottom of the baffles 2 can be detachably mounted on the baffles 2. After multiple frames are installed on the vehicle body 1 in sequence, the baffles 2 can be installed on the mounting side. The baffles 2 are equipped with locking parts that can be inserted into the locking holes on the side of the frame to provide secondary limiting for the frame and ensure that the frame will not shift during movement.

[0052] Because the frame is heavy and large, it is installed or disassembled using a hoisting method. After the frame is positioned on the vehicle body 1, the baffle 2 is installed on the mounting side. When removing the frame from the vehicle body 1, the locking mechanism on the mounting side must first be unlocked before the baffle 2 can be removed from the vehicle body 1. Therefore, disassembling or installing the frame is not only time-consuming and labor-intensive, but the removed frame also occupies space.

[0053] To address the aforementioned issues, please refer to some embodiments of this application. Figures 1-4 As shown, the material rack cart also includes a support assembly 3, which has a rotating end 311 and a sliding end 312. The sliding end 312 is slidably disposed on the support side and has a first position and a second position. The rotating end 311 is rotatably disposed on the side of the baffle 2. That is to say, the support assembly 3 is located between the baffle 2 and the cart body 1 and is in an inclined state. Please refer to Figures 1-4As shown in the figure, the sliding end 312 on one side is in the first position, at which time the baffle 2 is perpendicular to the vehicle body 1; the sliding end 312 on the other side is in the second position, at which time the baffle 2 is tilted. When the baffle 2 is locked to the frame, the sliding end 312 is in the first position; when the baffle 2 rotates relative to the vehicle body 1, the rotating end 311 rotates and the sliding end 312 moves from the first position to the second position to separate the baffle 2 from the frame. Please refer to [reference needed]. Figure 2 In the supported state, the support component 3, baffle 2, and vehicle body 1 form a stable triangle, which stabilizes baffle 2 on vehicle body 1 without hindering the installation and disassembly of the frame. This eliminates the need to remove or install baffle 2 from the installation side during frame installation and disassembly, saving time and manpower, and reducing the space occupied by the removed baffle 2.

[0054] Specifically, please refer to Figures 1-5 As shown, in some embodiments of this application, the support assembly 3 includes a support rod 31 and a slider 32. One end of the support rod is a rotating end 311, and the other end is a sliding end 312. The slider 32 is disposed on the support side and has a groove 321. The sliding end 312 has a slider 313 that matches the groove 321. The slider 313 slides within the groove 321 to achieve the sliding of the sliding end 312. Of course, the groove 321 can be directly disposed on the support side, while the method of disposing of it on the slider 32 and then installing the slider 32 on the support side is more convenient for manufacturing.

[0055] Further, please refer to Figure 5 As shown, in some embodiments of this application, the slide groove 321 includes a disassembly end 3211, a connecting part 3212, and a snap-fit ​​end 3213 connected in sequence. The slider 313 includes a slide rod 3131 and a limiting block 3132 located on the side of the slide rod 3131 away from the support rod 31. The diameter of the limiting block 3132 is larger than the diameter of the slide rod 3131 and larger than the width of the connecting part 3212 and the snap-fit ​​end 3213. The width of the connecting part 3212 and the snap-fit ​​end 3213 is larger than the diameter of the slide rod 3131, thereby enabling the slider 313 to be confined in the connecting part 3212 and the snap-fit ​​end 3213, so that the slide rod 3131 can slide in the connecting part 3212 and the snap-fit ​​end 3213. The diameter of the disassembly end 3211 is larger than the diameter of the limiting block 3132, so that when the slider 313 slides to the disassembly end 3211, it can be removed from the disassembly end 3211. Of course, it can also be installed from the disassembly end 3211. The slider 313 is in the first position when it is in the disassembly end 3211, and in the second position when it is in the locking end 3213.

[0056] When the baffle 2 is locked to the frame, the sliding end 312 can be removed from the disassembly end 3211. When installing and disassembling the frame in a relatively narrow space, in order to have enough operating space, the baffle 2 can also be removed from the vehicle body 1, and the sliding end 312 can be removed from the disassembly end 3211 to facilitate the installation or disassembly of the frame. After the frame is fully installed on the vehicle body 1, the baffle 2 and the sliding end 312 of the support component 3 can be reinstalled on the vehicle body 1 to meet the different needs of the material rack vehicle.

[0057] The locking end 3213 can restrict the position of the slider 313 to prevent the sliding end 312 from sliding along the connecting part 3212 under non-human factors when it is in the second position, thus preventing the baffle 2 from falling and hitting the base plate and causing danger. For details, please refer to Figure 1 and Figure 5 As shown, in some embodiments of this application, the snap-fit ​​end 3213 has a downward snap-fit ​​groove that can accommodate the slide rod 3131. When the slide rod 3131 slides along the connecting portion 3212 to the snap-fit ​​end 3213, it will move downward into the snap-fit ​​groove. The slide rod 3131 can no longer move due to the obstruction of the groove wall, thereby preventing the slide end 312 from disengaging from the second position.

[0058] Furthermore, in some embodiments of this application, please refer to Figure 1 and Figure 5 As shown, the groove wall of the snap-fit ​​groove is inclined downward toward the disassembly end 3211 away from the disassembly end 3211, so as to guide the slide bar 3131 to enter the disassembly end 3211 more easily when it moves to the end of the connecting part 3212 away from the disassembly end 3211, or to guide the slider 313 to enter the connecting part 3212 more easily from the snap-fit ​​groove when the sliding end 312 moves from the second position to the first position.

[0059] In order to better store the support rod 31 after the sliding end 312 is removed from the disassembly end 3211, please refer to some embodiments of this application. Figure 4 As shown, the material rack also includes a locking assembly 33, which is mounted on the side frame 21 on the side of the baffle 2. The distance between the axis of the locking assembly 33 and the axis of the rotating end 311 is the same as the distance between the axis of the limiting block 3132 and the axis of the rotating end 311. The limiting block 3132 has a locking hole 3133 in the center that matches the locking assembly 33. Please refer to... Figure 2 In its stored state, when the slider 313 is removed from the disassembly end 3211, it can rotate around the rotating end 311 to lock with the locking assembly 33. This prevents the support rod 31 from rotating under gravity to the side of the baffle 2, thus avoiding obstructing the storage of the baffle 2.

[0060] Please refer to some embodiments of this application. Figure 4As shown, the locking assembly 33 includes a knob 331, a lock cylinder, and a bolt 332. The knob 331 and the bolt 332 are respectively connected to two opposite sides of the lock cylinder. The lock cylinder can convert the rotation of the knob 331 into the extension and retraction of the lock cylinder. The knob 331 is located on the side of the side frame 21 away from the support rod 31 and has an unlocked position and a locked position. The lock cylinder is located inside the side frame 21, which can protect the lock cylinder from damage. The side frame 21 is provided with a clearance groove 23 that allows the limit block 3132 to enter. The bolt 332 is located in the clearance groove 23. When the slider 313 is removed from the disassembly end 3211, it can rotate around the rotating end 311 until the limit block 3132 slides along the clearance groove 23 to the lock cylinder entering the lock hole 3133, so as to lock the sliding end 312 onto the locking assembly 33. When knob 331 is in the unlocked position, the latch 332 is retracted, allowing the limiting block 3132 to slide away from the clearance groove 23. When knob 331 is in the locked position, the latch 332 extends and inserts into the lock hole 3133 to lock the limiting block 3132. The angle of knob 331 differs between the unlocked and locked positions; turning knob 331 allows switching between the unlocked and locked positions.

[0061] Please refer to some embodiments of this application. Figures 6-7 As shown, the mounting side is provided with a mounting groove 12, and a hook rod 13 is provided in the mounting groove 12. A mounting hook 24 is provided on the lower end surface of the baffle 2. The mounting hook 24 cooperates with the hook rod 13, and the mounting hook 24 can rotate along the outer circumference of the hook rod 13 to realize the rotation of the side plate relative to the vehicle body 1. The baffle 2 can be installed on the vehicle body 1 by hooking the mounting hook 24 with the hook rod 13, and the baffle 2 can be removed from the vehicle body 1 by removing the mounting hook 24 from the hook rod 13, making the baffle 2 easy to disassemble or install.

[0062] To prevent damage to the frame and vehicle body 1 from the impact force exerted by the side panels during movement, in some embodiments of this application, a plurality of abutment blocks 22 are evenly spaced on the baffle 2. The free ends of some abutment blocks 22 abut against the mounting side to buffer the impact force between the baffle 2 and the vehicle body 1, protecting the vehicle body 1 and the baffle 2 from damage. The free ends of other abutment blocks 22 abut against the frame to buffer the impact force between the baffle 2 and the frame, protecting the frame and the baffle 2 from damage.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
