Description

Technical Field

[0001] This utility model relates to the field of stacking rack technology, and more specifically to a stacking rack that can be quickly folded. Background Technology

[0002] Stacking racks, also known as pallet racks or stacking shelves, are handling and storage equipment derived from pallets. They are multifunctional equipment for unitizing goods, storing and distributing goods, and require the use of forklifts.

[0003] The existing stacking racks are single-function and cannot be folded, which means that people cannot fold them when placing them. As a result, the stacking racks take up too much storage space and cannot be placed in a limited space. Utility Model Content

[0004] The purpose of this invention is to provide a stacking rack that can be quickly folded, thereby solving the problem of traditional stacking racks occupying too much storage space.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A quick-folding stacking rack includes a base plate. Two sets of side baffle assemblies are symmetrically arranged at both ends of the upper surface of the base plate. Each set of side baffle assemblies includes two symmetrically arranged connecting seats. A column is rotatably connected to each connecting seat. A side plate is fixedly connected between the two columns. A connecting groove is formed on one side of each column. A sliding groove is formed on the upper surface of the base plate corresponding to the connecting groove. A connecting plate is provided between the sliding groove and the connecting groove. One end of the connecting plate is located in the connecting groove and hinged to the column. A slider is slidably connected in the sliding groove. The other end of the connecting plate is hinged to the slider. A limiting groove is formed at the bottom of the sliding groove. A positioning groove is formed at the top of the slider. The positioning groove is directly opposite the limiting groove. A limiting pin is slidably connected in the limiting groove. A spring is connected between the limiting pin and the bottom of the limiting groove. A control groove is formed at the bottom of the limiting groove, communicating with the outside of the base plate. A pedal is slidably connected in the control groove. One end of the pedal is fixedly connected to the bottom of the limiting pin, and the other end of the pedal extends to the outside of the base plate.

[0007] Furthermore, a limiting plate is rotatably connected to the bottom of the outer side wall of the side plate, an installation groove is provided on the outer side wall of the bottom plate, an elastic positioning pin is provided in the installation groove, and a limiting hole is provided on the limiting plate corresponding to the elastic positioning pin.

[0008] Furthermore, a lifting handle is provided at the top of the outer side wall of the side plate.

[0009] Furthermore, the bottom of the base plate is provided with four support legs.

[0010] Furthermore, the support legs are arranged in a one-to-one correspondence with the columns, and the bottom of the support legs is provided with stacking grooves that match the top of the columns.

[0011] Furthermore, a guide rod is vertically fixed inside the control slot, and the pedal is slidably sleeved on the guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When the pedal is pressed, the limiting pin disengages from the positioning groove of the slider, allowing the slider to slide within the groove. This causes the connecting plate to move, which in turn causes the column to rotate around the connecting seat, enabling the side plate and column to fold towards the base plate. After the pedal is released, the spring pushes the limiting pin to reset, fixing the slider in a specific position and keeping the stacking rack in its unfolded state. This design facilitates the folding and storage of the stacking rack when not in use, saving storage space and improving space utilization. At the same time, the operation is simple and convenient, allowing for quick completion of folding and unfolding actions, thus improving work efficiency. Attached Figure Description

Detailed Implementation

[0019] like Figures 1 to 3As shown, a quick-folding stacking rack includes a base plate 1. Two sets of side baffle assemblies are symmetrically arranged at both ends of the upper surface of the base plate 1. Each set of side baffle assemblies includes two symmetrically arranged connecting seats 2. A column 3 is rotatably connected to each connecting seat 2. A side plate 4 is fixedly connected between the two columns 3. A connecting groove 301 is formed on one side of each column 3. A sliding groove 101 is formed on the upper surface of the base plate 1 corresponding to the connecting groove 301. A connecting plate 5 is provided between the sliding groove 101 and the connecting groove 301. One end of the connecting plate 5 is located within the connecting groove 301 and hinged to the column 3. A slider 6 is slidably connected within the sliding groove 101. The other end of the connecting plate 5 is hinged to the slider 6. A limiting groove 102 is provided at the bottom of the sliding groove 101. A positioning groove 601 is provided at the top of the slider 6. The positioning groove 601 is set opposite to the limiting groove 102. A limiting pin 7 is slidably connected in the limiting groove 102. A spring 8 is connected between the limiting pin 7 and the bottom of the limiting groove 102. A control groove 103 is provided at the bottom of the limiting groove 102, which communicates with the outside of the base plate 1. A pedal 9 is slidably connected in the control groove 103. One end of the pedal 9 is fixedly connected to the bottom of the limiting pin 7, and the other end of the pedal 9 extends to the outside of the base plate 1.

[0020] A limiting plate 10 is rotatably connected to the bottom of the outer side wall of the side plate 4. An installation groove is provided on the outer side wall of the base plate 1, and an elastic positioning pin 11 is provided in the installation groove. A limiting hole is provided on the limiting plate 10 corresponding to the elastic positioning pin 11. When the stacking rack is unfolded for use, the limiting plate 10 is rotated so that its limiting hole is aligned with the elastic positioning pin 11. The elastic positioning pin 11 is inserted into the limiting hole, which can further fix the position of the side plate 4, enhance the overall stability of the stacking rack, prevent the side plate 4 from shaking or shifting during the process of carrying goods, and ensure the safety of goods storage.

[0021] A lifting handle 12 is provided on the top of the outer side wall of the side panel 4. The lifting handle 12 makes it easy for operators to grip and exert force when moving the stacking rack. Whether the stacking rack is being moved after being folded or its position is being adjusted in the unfolded state, the lifting handle 12 provides a convenient point of leverage, reducing the labor intensity of operators and improving the convenience of operation.

[0022] The bottom of the base plate 1 is provided with four support legs 13.

[0023] The support leg 13 is provided in a one-to-one correspondence with the column 3. The bottom of the support leg 13 is provided with a stacking groove 14 that matches the top of the column 3. When multiple stacking racks are stacked, the column 13 of the lower stacking rack can be inserted into the stacking groove 14 of the support leg 13 of the upper stacking rack to achieve precise positioning and stable stacking between stacking racks.

[0024] A guide rod 15 is vertically fixed inside the control groove 103, and the pedal 9 is slidably sleeved on the guide rod 15. The guide rod 15 provides guidance for the sliding of the pedal 9, ensuring that the pedal 9 will not deviate or get stuck during the sliding process, so that the pedal 9 can smoothly drive the limit pin 7 to move up and down, ensuring the reliability and stability of the stacking rack folding and unfolding operation.

[0025] Working principle:

[0026] When the stacking rack is needed, the operator steps on pedal 9, which causes the limit pin 7 to slide downwards, compressing the spring 8. The operator then pulls the side plate 4 through the handle 12, causing the column 3 to rotate. The column 3, through the connecting plate 5, causes the slider 6 to slide along the slide groove 101. The operator releases pedal 9, and the limit pin 7, under the action of the spring 8, inserts into the positioning groove 601 of the slider 6, fixing the slider 6 in the slide groove 101. This keeps the side plate 4 perpendicular to the column 3, forming a stable storage structure. At this time, the limit plate 10 at the bottom of the outer wall of the side plate 4 can be rotated to a suitable position, allowing the elastic positioning pin 11 to be inserted into the limit hole, further fixing the side plate 4.

[0027] When the stacking rack needs to be folded for storage, the operator steps on pedal 9. Pedal 9 moves the limiting pin 7 downward, compressing the spring 8 and causing the limiting pin 7 to disengage from the positioning groove 601 of the slider 6. At this time, the slider 6 can slide freely within the slide groove 101. The operator rotates the side plate 4, which causes the column 3 to rotate around the connecting seat 2. The connecting plate 5 moves along with the sliding of the slider 6 and the rotation of the column 3, thus folding the side plate 4 and the column 3 towards the base plate 1. After folding, the pedal 9 is released, and the spring 10 returns to its original shape.

[0028] This invention enables the stacking rack to fold quickly through the coordinated operation of its components, solving the problem of large space occupation of traditional stacking racks, improving space utilization, and making it simple, safe and reliable to operate during use, thus reducing the labor intensity of operators.
