Description

Technical Field

[0001] This application relates to the technical field of motor accessory transportation, and in particular to an adjustable pallet rack. Background Art

[0002] During the production process of motor accessories, it is usually necessary to transfer the accessories between different workstations to complete the processing and grinding of the workpieces. In the above transfer process, in order to improve the transfer efficiency of the workpieces, the existing method is usually to use a pallet rack with a multi-layer structure, that is, to put multiple workpieces into the pallet rack one by one. When the number of workpieces carried by the pallet rack reaches a certain value, the pallet rack is placed on a transport trolley to transport multiple workpieces to the designated position at one time through the transport trolley.

[0003] However, in actual use, since the carrying capacity of the existing pallet rack is fixed and the layer height on the pallet rack is fixed, and the sizes of the workpieces to be transported are diverse. When transporting workpieces with smaller sizes, even if more workpieces are placed on the pallet rack, there is still a large amount of space wasted in the height direction of the pallet rack; while when transporting workpieces with larger sizes, it is easy to occur that the workpiece cannot be placed in the pallet rack because the height of the workpiece is greater than the layer height of the pallet rack, and the overall use is relatively inconvenient.

[0039] The following further Figure 1 - with reference to the Figure 8 describes the present application in detail.

[0040] Embodiment 1 of the present application discloses an adjustable pallet rack.

[0041] Embodiment 1:

[0042] Refer to Figure 1 and Figure 2 , an adjustable pallet rack includes at least two horizontally placed laminates 1 and support columns 2. At least two laminates 1 are evenly spaced in the vertical direction. The support columns 2 are located between two adjacent laminates 1. There are multiple support columns 2, and the multiple support columns 2 are evenly spaced on the laminate 1. In this embodiment, taking two laminates 1 as an example for structural description, the support columns 2 are preferably set to nine, and the nine support columns 2 are distributed in a rectangular array; in use, through the combined action of the nine support columns 2, the structural strength of the pallet rack is ensured.

[0043] Refer to Figure 2 and Figure 3, the support column 2 is composed of two parts: an upper column body 22 and a lower column body 21. Among them, the bottom end of the lower column body 21 is fixed to the lower layer board 1 by bolts. A sliding groove 211 is opened at the top end of the lower column body 21. The upper column body 22 is located directly above the lower column body 21, and the bottom end of the upper column body 22 is slidably arranged in the sliding groove 211. A hollow groove is also opened at the bottom end of the upper column body 22. The top end of the upper column body 22 is fixed to the bottom wall of the upper layer board 1 by bolts. A positioning structure 3 is arranged on the lower column body 21. During use, the staff can adjust the height of the upper column body 22 to adjust the distance between the two layer boards 1, and then fix the height of the upper column body 22 through the positioning structure 3, thereby fixing the height between the two layer boards 1, so as to adapt to workpieces of different sizes.

[0044] Refer to Figure 3 and Figure 4 , the positioning structure 3 includes two parts: a positioning bolt 31 and a locking nut 32. A positioning hole 212 is penetrated and opened on the lower column body 21. An adjusting hole 221 is penetrated and opened on the upper column body 22. There are several adjusting holes 221, and several said adjusting holes 221 are evenly distributed at intervals along the height direction of the upper column body 22. The positioning bolt 31 is inserted into the positioning hole 212 and one of the adjusting holes 221. The locking bolt is threadedly connected to the positioning bolt 31. During use, first remove the locking nut 32 and take it out, and pull out the positioning bolt 31. After that, slide the upper column body 22 to the specified height, and then pass one end of the positioning bolt 31 through the positioning hole 212 and a corresponding adjusting hole 221 in sequence, and then screw the locking bolt onto the positioning bolt 31, so as to complete the positioning of the upper column body 22.

[0045] Refer to Figure 3 and Figure 4 , in order to ensure the structural stability after the height of the support column 2 is adjusted, two groups of positioning structures 3 can be arranged, and the two groups of positioning structures 3 are evenly distributed at intervals along the length direction of the lower column body 21. There are also two groups of positioning holes 212 and adjusting holes 221, and the positions of the two groups of positioning holes 212 and adjusting holes 221 correspond to the positioning structures 3 one by one. During use, through the combined use of the two groups of positioning structures 3, the positioning of the upper column body 22 is further ensured, so as to achieve the purpose of strengthening the structural strength of the support column 2.

[0046] Refer to Figure 1 and Figure 2, a number of weight - reducing grooves 11 are provided on the laminate 1. During use, the weight of the laminate 1 is reduced through the weight - reducing grooves 11. On the one hand, it is convenient for the staff to pick up the laminate 1, and on the other hand, it saves the manufacturing cost; in addition, an identification card slot is provided at one end of the laminate 1, and an identification plate 7 is placed in the identification card slot; during use, the workpiece information on the laminate 1 can be recorded on the corresponding identification plate 7 of the corresponding layer, so as to complete the classified placement, thus facilitating subsequent retrieval; at the same time, in order to increase the stability of workpiece placement, a limiting structure for preventing the workpiece from moving in the horizontal direction is also provided on the laminate. The limiting structure can be realized by using clamping claws or partition plates.

[0047] The implementation principle of the embodiment of this application is as follows: During use, the staff can place multiple workpieces on the laminate 1 one by one. After the first laminate 1 stores a certain amount of workpieces, the second laminate 1 is installed on the first laminate 1 through the support column 2, and then the height of the second laminate 1 is adjusted. After the adjustment is completed, the positioning bolts 31 are inserted into the corresponding positioning holes 212 one by one and fixed by the locking nuts 32, so as to fix the height of the second laminate 1. In this way, multiple laminates 1 can be combined together, and at the same time, it can adapt to the loading of workpieces of different sizes; in addition, when there are more laminates 1, the workpiece information on the corresponding laminate 1 can be recorded on the corresponding identification plate 7, thus facilitating subsequent retrieval and improving the convenience of using the overall device.

[0048] Embodiment 2:

[0049] Refer to Figure 5 , the difference between this embodiment and Embodiment 1 is that a connecting rod 4 is provided between two groups of positioning bolts 31 on the same lower column 21. One end of the connecting rod 4 is welded and fixed to one positioning bolt 31, and the other end is welded and fixed to the other positioning bolt 31; during use, in Embodiment 1, the user needs to insert the two positioning bolts 31 into the corresponding positioning holes 212 one by one, which is relatively cumbersome. In this embodiment, the two groups of positioning bolts 31 are connected together through the connecting rod 4, so as to insert the two groups of positioning bolts 31 into the corresponding positioning holes 212 at one time, and the using method is simpler than that in Embodiment 1.

[0050] Refer to Figure 5 , in this embodiment, the connecting rod 4 and the two positioning bolts 31 can also be integrally formed directly to form a U - shaped rod - like structure, and threads for threaded cooperation with the locking nut 32 are provided at both ends.

[0051] Embodiment 3:

[0052] Refer to Figure 6 and Figure 7, The difference between this embodiment and Embodiment 1 is that the positioning structure 3 can also be composed of a fixed column 33, a sliding column 34, and an insertion block 35. Among them, there are two fixed columns 33. Both fixed columns 33 are located in the sliding groove 211, and the bottom end of the fixed column 33 is fixed to the bottom wall of the sliding groove 211 by bolts. The sliding column 34 is located between the two fixed columns 33. The top end of the sliding column 34 extends into the hollow groove and is fixedly connected to the bottom wall of the hollow groove by bolts. The top end of the fixed column 33 is provided with an insertion block 35. The insertion block 35 slides along the length direction of the lower column body 21, and the two insertion blocks 35 are arranged oppositely.

[0053] Refer to Figure 6 and Figure 7 , A first set of teeth 351 is integrally formed on the insertion block 35. There are multiple first set of teeth 351, and the multiple first set of teeth 351 are evenly spaced along the height direction of the insertion block 35. Second set of teeth 341 are formed on both the left and right side walls of the sliding column 34. There are several second set of teeth 341, and the several second set of teeth 341 are evenly spaced along the height direction of the sliding column 34. A first card slot is formed between two adjacent second set of teeth 341, and a second card slot is formed between two adjacent first set of teeth 351. When in use, after the sliding column 34 moves to the specified height, the insertion block 35 can be moved so that the first set of teeth 351 is embedded in the first card slot. At this time, the second set of teeth 341 is also embedded in the second card slot. In this way, the clamping and fixing of the sliding column 34 is formed by the mutual engagement of the first set of teeth 351 and the second set of teeth 341, thereby achieving the purpose of positioning the sliding column 34.

[0054] Refer to Figure 7 and Figure 8 , A locking structure 5 is also provided on the lower column body 21. When in use, the insertion block 35 is positioned through the locking structure 5 to prevent the first set of teeth 351 on the insertion block 35 from disengaging from the first card slot. The locking structure 5 includes a lever 51 and a clamping rod 52. A first relief groove 213 is opened on the lower column body 21, and a second relief groove 222 is opened on the upper column body 22. One end of the lever 51 is located outside the lower column body 21. The other end of the lever 51 passes through the first relief groove 213 and the second relief groove 222 and is threadedly connected to the insertion block 35. The lever 51 can drive the insertion block 35 to slide in the horizontal direction. A clamping groove 511 is opened at the end of the lever 51 located outside the lower column body 21. The clamping rod 52 can be embedded in the clamping groove 511. Limiting rods 6 are integrally formed at both ends in the length direction of the clamping rod 52. The limiting rods 6 are perpendicular to the clamping rod 52. The clamping rod 52 and the two limiting rods 6 together form a U-shaped rod-like structure.

[0055] Refer to Figure 7 and Figure 8The locking groove 511 is also provided with a magnet assembly. When in use, the first locking tooth 351 and the second locking tooth 341 are meshed with each other by moving the lever 51, and then the locking rod 52 is embedded in the locking groove 511, and the limiting rods 6 at both ends are respectively abutted against the corresponding side walls of the lever 51, so as to form a limit for the lever 51, thereby preventing the lever 51 from driving the plug block 35 to slide and disengage from the sliding column 34; at the same time, the locking rod 52 is magnetically adsorbed in the locking groove 511 through the magnet assembly, so as to prevent the locking rod 52 from disengaging from the locking groove 511, thereby ensuring the locking stability of the locking rod 52, and then ensuring the stability of the support column 2 after the height is adjusted.

[0056] The implementation principle of the embodiment of the present application is as follows: when in use, the staff removes the clamping rod 52 and slides the plug block 35 in the direction away from the sliding column 34, so that the first locking tooth 351 on the plug block 35 is disengaged from the first locking groove, and then the height of the layer board 1 can be adjusted. When the adjustment is completed, the lever 51 is moved in the opposite direction, and the plug block 35 is driven by the lever 51 to move towards the sliding column 34 until the first locking tooth 351 and the second locking tooth 341 are meshed with each other, so that the sliding column 34 can be positioned, thereby achieving the fixing of the height position of the upper column body 22. Finally, the clamping rod 52 is put back into the clamping groove 511 and fixed on the lever 51 by the magnet assembly, so that the limit rods 6 at both ends of the clamping rod 52 abut against the lever 51 to limit the position, thereby improving the clamping stability of the height position of the upper column body 22, thereby ensuring the structural stability of the support column 2 after the height is adjusted.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
