Description

Technical Field

[0001] The utility model relates to the technical field of pallet racks, in particular to a pallet rack. Background Art

[0002] Pallet racks are a combination of pallets and shelves derived from pallets. They are also called stacking racks, column pallets, etc. They are widely used in the field of logistics and transportation. They allow warehouses to store more goods, save floor space, and are also convenient for staff to carry out transfer work.

[0003] A pallet rack is mainly composed of a group of pallets and four groups of support columns. In actual use, workers directly stack the goods to be stored on the pallets, and then use a forklift to move the pallet rack to the designated location. Since the existing pallet rack only limits the position of the goods by four groups of support columns, when using a forklift to transport some cylindrical goods such as steel pipes and cloth rolls, it is easy for the cylindrical goods to roll and shift. In severe cases, they may fall off the pallet, posing a certain safety hazard. Therefore, we propose a pallet rack to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 The top of described support column 3 is provided with support column 3, and the top of described support column 3 is provided with support column 3. The outer side of support column 3 is provided with connecting sleeve 4, and the side of connecting sleeve 4 close to each other is connected by limiting plate 5. A rectangular groove 6 is opened inside the limiting plate 5, and two groups of connecting strips 7 are symmetrically inserted inside the rectangular groove 6. The front and back sides of the two groups of connecting strips 7 away from each other are connected to limit rods 8 respectively, and the position of limit rod 8 corresponds to the position of support column 3. The limit rod 8 passes through the inner wall of limit plate 5 and connecting sleeve 4 in sequence and extends into support column 3, and the interior of support column 3 is equidistantly provided with positioning grooves adapted to limit rod 8 from top to bottom, and the side of connecting strip 7 is connected with pull rod 10, and pull rod 10 extends to the outside of limiting plate 5, and the interior of limiting plate 5 is provided with slideway adapted to pull rod 10, so as to meet the normal movement of pull rod 10.

[0023] Further, refer to Figure 1 and Figure 2 It can be seen that the bottom end of the support column 3 is connected to the positioning rod 13, and the top of the column 2 is provided with an insertion groove adapted to the positioning rod 13. The top of the column 2 is connected to the positioning rod 13 by a bolt. During the transportation of this device, the four groups of support columns 3 can be pulled out from the inside of the four groups of columns 2 through the mutual cooperation of the positioning rod 13 and the bolts to reduce the footprint of the device, thereby facilitating the packaging and transportation of the device.

[0024] Further, refer to Figure 3 It can be seen that grooves are evenly opened inside the connecting sleeve 4, and balls 15 are installed inside the grooves. The position of the balls 15 is staggered with the position of the limit rod 8. Since the balls 15 and the limit rod 8 are staggered, the limit rod 8 can be smoothly inserted into the support column 3 and the connecting sleeve 4. The mutual cooperation between the grooves and the balls 15 can prevent the outer wall of the support column 3 from being damaged due to friction.

[0025] Further, refer to Figure 1 and Figure 2 It can be seen that the bottom end of the limiting plate 5 is glued with a rubber plate 14, and the lower surface of the rubber plate 14 is evenly distributed with anti-slip particles. Through the mutual cooperation of the rubber plate 14 and the anti-slip particles, the limiting effect of cylindrical goods can be effectively improved.

[0026] Further, refer to Figure 1It can be seen that two groups of handles 11 are symmetrically connected to the upper side of the limit plate 5, and the two groups of handles 11 are distributed at the edge positions of the limit plate 5. The two groups of handles 11 set at the edge positions can facilitate the staff to push the position of the limit plate 5 up and down. In addition, since the overall height of the device is limited, it is convenient for the staff to push the limit plate 5 to the appropriate position.

[0027] Further, refer to Figure 2 and Figure 4 It can be seen that the inner wall of the rectangular groove 6 is connected to the guide rod 12, and the interior of the connecting bar 7 is provided with a hole adapted to the guide rod 12. Through the mutual cooperation between the hole and the guide rod 12, the stability of the connecting bar 7 during movement can be effectively improved.

[0028] Further, refer to Figure 2 and Figure 4 It can be seen that two groups of springs 9 are provided inside the rectangular groove 6, and the two ends of the two groups of springs 9 are fixedly connected to the connecting strips 7 respectively. The springs 9 connected between the two groups of connecting strips 7 can effectively ensure the reliability of the four groups of limiting rods 8 inserted into the four groups of support columns 3.

[0029] When the load is lifted, the loaders 10 can be lifted up and the loaders 10 can be lifted up by the pull rods 10. When the load is lifted, the loaders 10 can be lifted up and the loaders 10 can be lifted up by the pull rods 10.
