Description

Technical Field

[0001] The utility model belongs to the technical field of collection boxes, and in particular relates to a foldable material carrying device. Background Art

[0002] Metal scrap refers to used and discarded metals, including metal wires, bars, blocks, sheets, etc. Metal scrap can be recycled after further processing. In workshop production, collection boxes are needed to collect metal scrap for subsequent processing. Most existing collection boxes are welded to form a material frame. Although they can also serve the purpose of collection, due to the fixed structure, when less material is put in, due to the large height difference, it will generate a lot of noise. When taking out, the irregular scrap will form mutual squeezing, making it difficult to take out all at once, affecting work efficiency. Secondly, the traditional welded fixed material box cannot be folded, takes up a lot of space, and cannot be overlapped, which is not conducive to transportation, storage, and rotation.

[0003] To solve the above problems, this application proposes a foldable material carrying device. Utility Model Content

[0030] See also Figure 1-8As shown, the utility model is a foldable material carrying device, comprising a support frame 1, a bottom plate 11 being laid flat on the support frame 1, support legs 12 being fixedly provided at the four corners of the support frame 1, vertically pluggable uprights 2 being provided in the support legs 12, and the uprights 2 can be folded toward the inside of the support frame 1 after being pulled out, and an integral plate 3 is provided at the front and rear ends of the support frame 1, and each integral plate 3 is fixed to two uprights 2 at the same end at the same time, a No. 1 plate 4 is provided on the left and right sides of the support frame 1, a No. 2 plate 5 is hinged on the No. 1 plate 4, and a latch lock 6 is provided between the upper sides of the No. 2 plate 5 and the uprights 2, and the No. 1 plate 4 is vertically plugged into the support frame 1 and can be rotated and folded after being pulled out.

[0031] Among them, a vertical positioning frame 13 is provided inside the support leg 12 for vertically inserting the lower end of the upright pole 2, a movable groove 14 is provided on the side of the support leg 12, and a positioning groove 15 is provided on the top of the support leg 12. A movable pin 21 that can slide and rotate in the movable groove 14 is fixed to the side of the lower end of the upright pole 2, and a positioning block 22 that is vertically plugged into the positioning groove 15 is fixed on the side of the upright pole 2. In this embodiment, the movable pin 21 and the movable groove 14 can not only connect the upright pole 2 and the support leg 12, but also rotate while sliding, thereby ensuring the convenience of folding, unfolding and limiting the upright pole 2 and the integrated panel 3. The connection between the positioning block 22 and the positioning groove 15 is used for positioning the middle part of the upright pole 2 when it is vertically plugged into the vertical positioning frame 13, thereby improving the stability of the upright pole 2 and thereby improving the deployment reliability of the entire device.

[0032] Among them, a limiting plate 16 is fixed at the support frame 1 near the support leg 12, and a limiting rod 41 that can move in the limiting plate 16 is fixed to the bottom end of the side of the No. 1 plate 4. In this embodiment, the limiting rod 41 can move upward and rotate inside the limiting plate 16, causing the snap-in pin 23 to disengage from the L-shaped slot 42. At the same time, after being plugged vertically downward, the bottom of the No. 1 plate 4 is attached to the support frame 1 and the locking action of the snap-in pin 23 and the L-shaped slot 42 can effectively ensure the stability of the No. 1 plate 4 when it is unfolded.

[0033] Among them, a snap-in pin 23 is fixed to the upper end of the side of the vertical pole 2, and an L-shaped slot 42 is provided on the upper end of the side of the No. 1 plate 4 to cooperate with the snap-in pin 23. In this embodiment, by setting the snap-in pin 23 and the L-shaped slot 42, a limit can be formed on the upper end of the No. 1 plate 4, while ensuring the stability of the No. 1 plate 4 and the No. 2 plate 5, and flexible use.

[0034] Among them, the No. 2 plate 5 is folded outward on the No. 1 plate 4, and the No. 1 plate 4 drives the No. 2 plate 5 to fold toward the inside of the support frame 1 at the same time. The integrated plate 3 is folded toward the inside of the support frame 1 and partially overlaps on the No. 2 plate 5. In this embodiment, the outward folding of the No. 2 plate 5 can avoid conflict with the metal waste contained inside during use, and also facilitates the folding of the two groups of No. 1 plates 4 and No. 2 plates 5.

[0035] Among them, the top of the upright 2 can be vertically connected to the bottom of the support leg 12, and after the integrated plate 3, the first plate 4, and the second plate 5 are folded, the top of the support leg 12 is in a protruding state and can be stacked in the vertical direction. In this embodiment, Figure 2 and Figure 6 As shown, the application can be stacked vertically when unfolded or folded, providing greater practical flexibility.

[0036] It can be understood that the utility model sets the four vertical sides of the material carrying box into a folding structure, which can effectively reduce the occupied space and can also be stacked, which is conducive to use when there is no metal scrap. Secondly, the vertical plug-in and pull-out rotation and the mutual cooperation of the latch lock can not only ensure the reliability of the box after unfolding, but also facilitate quick folding and unfolding, and have high flexibility.

[0037] A specific application of this embodiment is: Figure 1 The figure shows the expanded state, at which time the bottom of the upright pole 2 is inserted into the vertical positioning frame 13, the movable pin 21 is located at the bottom of the movable groove 14, the positioning block 22 is engaged with the positioning groove 15, the limiting rod 41 is located at the bottom of the limiting piece 16, the engaging pin 23 is stuck in the L-shaped slot 42, and the latch lock 6 locks the upper end of the second plate 5 with the upright pole 2, as shown in FIG. Figure 2 In the state shown, the bottom of the support leg 12 can be stacked with the top of the upright pole 2;

[0038] Folding steps as follows Figure 3-5 As shown, the details are as follows:

[0039] To open the second plate 5 separately: disengage the latch locks 6 on both sides of the upper end of the second plate 5 from the upright pole 2, and then rotate the second plate 5 outwards through the shaft connecting the second plate 5 and the outer side of the first plate 4 and fold it outside;

[0040] The first plate 4 and the second plate 5 are folded inward: Hold the first plate 4 and the second plate 5 at the same time and lift them vertically upward, then rotate them toward the inside of the support frame 1. At this time, the limiting rod 41 moves to the inner upper end of the limiting plate 16 and rotates, and the L-shaped slot 42 is disengaged from the engaging pin 23, and the folded first plate 4 and the second plate 5 can be folded onto the bottom plate 11;

[0041] The integrated panel 3 and the vertical rod 2 are folded inward: after the integrated panel 3 is lifted upward, the bottom of the vertical rod 2 is driven to separate from the vertical positioning frame 13. At this time, the positioning block 22 is separated from the positioning slot 15, and the movable pin 21 moves upward in the movable slot 14. Then, the vertical rod 2 and the integrated panel 3 are rotated inward, and the movable pin 21 rotates along with it at the upper end of the movable slot 14 until the integrated panel 3 is folded onto the No. 1 panel 4 and the No. 2 panel 5. In this state, the support legs 12 are in a protruding state, and the support legs 12 can be used as shown in the following figure. Figure 6 The states shown are stacked.
