Description

Technical Field

[0001] This utility model belongs to the field of splicing frame technology, specifically relating to a foldable industrial splicing frame with a quick locking mechanism. Background Technology

[0002] Scaffolding is frequently used in many fields such as industrial production, logistics warehousing, and exhibitions. Scaffolding is used to support goods, build temporary work platforms, or serve as protective structures; its performance and ease of use have a crucial impact on work efficiency and safety.

[0003] Traditional industrial modular racking systems have many shortcomings. In terms of space utilization, many existing modular racking systems have fixed structures that cannot be effectively folded and stored when not in use, occupying a significant amount of space. This is a major problem for space-constrained storage environments or scenarios where modular racking systems need to be frequently transported.

[0004] From the perspective of assembly and disassembly, the existing splicing frame assembly process is cumbersome and complex. Some splicing frames require a large number of bolts, nuts, and other connectors, which need to be tightened one by one during assembly. This not only consumes a lot of time and manpower but also requires a high level of skill from the operators. In some scenarios where a work platform needs to be set up urgently, such as emergency repair sites, the lengthy assembly process can delay the repair opportunity and cause greater losses. Similarly, disassembly requires a lot of effort to remove the connectors, making the process cumbersome and inefficient.

[0005] To address this, we propose a folding industrial splicing rack with a quick-locking mechanism. This device enables rapid unfolding, compact storage, and convenient adjustment, saving splicing time and improving work efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a folding industrial splicing rack with a quick-locking mechanism. This device can achieve rapid unfolding, compact storage, and convenient adjustment, saving splicing time and improving work efficiency.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A folding industrial splicing rack with a quick locking mechanism includes a base plate, connecting blocks on both sides of the top of the base plate, a height adjustment component on the connecting blocks, a first hollow shell on the height adjustment component, a rotating support component on the first hollow shell, and two U-shaped crossbeams on the rotating support component.

[0009] The base plate has a first storage slot and a second storage slot. The first storage slot has a vertical support rod that is hinged to the base plate. The second storage slot has a horizontal railing. The horizontal railing is connected to the vertical support rod by a rotating pin.

[0010] Furthermore, the height adjustment includes a fixing block disposed on the top of the connecting block and a second hollow shell disposed at the bottom of the first hollow shell. The fixing block slides inside the second hollow shell, and the fixing block is provided with a plurality of first locking holes, and the second hollow shell is provided with a second locking hole. The first locking holes and the second locking holes are provided with elastic locking components inside.

[0011] Furthermore, the elastic locking assembly includes a hollow cylinder disposed outside the second hollow housing, a spring disposed inside the hollow cylinder, a piston disc disposed on one side of the spring, a movable rod mounted on one side of the piston disc, and a locking rod mounted on the end of the movable rod away from the piston disc.

[0012] Furthermore, the rotating support assembly includes a threaded hole on the top of the first hollow shell and through slots on both sides of the first hollow shell. A threaded rod is provided inside the threaded hole, and a threaded sleeve that slides on the inner wall of the first hollow shell is provided on the threaded rod. Both sides of the threaded sleeve are provided with meshing teeth. A gear is rotatably provided inside the through slot. The gear meshes with the meshing teeth, and the outer side of the gear is connected to the U-shaped crossbeam plate.

[0013] Furthermore, the horizontal railing consists of two support rods and a movable rod, and the two support rods are provided with through holes on the side that is close to each other, so that the movable rod can move.

[0014] Furthermore, the bottom of the base plate is provided with movable pulleys.

[0015] The technical effects achieved by this utility model are as follows:

[0016] When not in use, the frame is in a compact, folded storage state. Two U-shaped crossbeams are attached to the first hollow shell, the vertical support rods are stably placed in the first storage slot, and the horizontal railings are hidden in the second storage slot. The entire frame occupies little space, facilitating transportation and storage, reducing space costs and handling difficulty. In use, first operate the rotating support assembly; the U-shaped crossbeams gradually unfold to a horizontal position, quickly establishing the basic frame structure and preparing for subsequent support. After the frame is formed, the vertical support rods are removed from the first storage slot. The vertical support rods are connected to the base plate via a hinge point, allowing for smooth rotation around this point on the base plate during removal. As they rotate, the vertical support rods continuously adjust their angle; when they reach the appropriate position, they stably support the horizontal U-shaped crossbeams, greatly enhancing the vertical load-bearing capacity of the frame and ensuring its stability. During the rotation and removal of the vertical support rods, they are connected to the horizontal railings by a rotating pin. The rotation of the vertical support rod generates tension through the rotating pin, pulling the horizontal railing out of the second storage slot. After being pulled out, the horizontal railing is quickly adjusted to a suitable position, spanning the horizontal area of ​​the splicing frame, forming an effective lateral barrier to prevent items from sliding or shifting laterally, thus improving the protective and load-bearing functions of the splicing frame.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: a folding industrial splicing frame with a quick locking mechanism includes a base plate 1, connecting blocks 2 are provided on both sides of the top of the base plate 1, a height adjustment component is provided on the connecting blocks 2, a first hollow shell 3 is provided on the height adjustment component, a rotating support component is provided on the first hollow shell 3, and two U-shaped crossbeams 5 are provided on the rotating support component.

[0026] The base plate 1 has a first storage slot 6 and a second storage slot 7. The first storage slot 6 has a vertical support rod 8 that is hinged to the base plate 1. The second storage slot 7 has a horizontal railing 9. The horizontal railing 9 and the vertical support rod 8 are connected by a rotating pin.

[0027] The height adjustment includes a fixing block 4 set at the top of the connecting block 2 and a second hollow shell 10 set at the bottom of the first hollow shell 3. The fixing block 4 slides inside the second hollow shell 10, and a plurality of first locking holes 11 are provided on the fixing block 4. A second locking hole 12 is provided on the second hollow shell 10. Elastic locking components are provided inside the first locking holes 11 and the second locking holes 12.

[0028] The elastic locking assembly includes a hollow cylinder 13 disposed outside the second hollow housing 10, a spring 14 disposed inside the hollow cylinder 13, a piston disc 15 disposed on one side of the spring 14, a movable rod 16 mounted on one side of the piston disc 15, and a locking rod 17 mounted on the end of the movable rod 16 away from the piston disc 15.

[0029] By stretching the locking rod 17, the locking rod 17 drives the movable rod 16 to stretch the piston disc 15 and the spring 14, thereby pulling the locking hole out from the first locking hole 11 and the second locking hole 12. Then, the fixing block 4 moves inside the second hollow housing 10, thereby achieving the effect of adjusting the height. After the height adjustment is completed, the spring force of the spring 14 causes the locking rod 17 to enter the first locking hole 11 and the second locking hole 12 for locking.

[0030] Meanwhile, the rotating support assembly includes a threaded hole on the top of the first hollow shell 3 and through slots 18 on both sides of the first hollow shell 3. A threaded rod 19 is provided inside the threaded hole, and a threaded sleeve 20 that slides on the inner wall of the first hollow shell 3 is provided on the threaded rod 19. Both sides of the threaded sleeve 20 are provided with meshing teeth 21. A gear 22 is rotatably provided inside the through slots 18. The gear 22 meshes with the meshing teeth 21, and the outer side of the gear 22 is connected to the U-shaped crossbeam plate 5.

[0031] First, by rotating the threaded rod 19 inside the threaded hole, the threaded rod 19 drives the threaded sleeve 20 to move downward. When the threaded sleeve 20 moves downward, it drives the gear 22 to rotate through the meshing teeth 21. When the gear 22 rotates, it drives the U-shaped horizontal plate to rotate. The U-shaped horizontal beam plate 5 gradually unfolds to the horizontal position, quickly building the basic shape of the frame.

[0032] The horizontal railing 9 consists of two support rods 23 and a movable rod 24. The two support rods 23 are provided with through holes on the side that are close to each other, so that the movable rod 24 can move. This arrangement allows the two support rods 23 to move relative to each other when folded and stored, thereby achieving the effect of extension and retraction. Therefore, the horizontal railing 9 can be stored inside the second storage slot 7.

[0033] The bottom of the U-shaped crossbeam plate 5 has multiple connecting holes (not shown in the figure). The connecting holes match the vertical support rod 8. This arrangement allows the rotated vertical support rod 8 to enter the connecting hole and lock in place.

[0034] The bottom of the base plate 1 is equipped with movable pulleys, which facilitate both movement and fixation.

[0035] The working principle of this utility model is as follows: When not in use, the splicing frame is in a compact folded storage state. Two U-shaped crossbeams 5 are attached to the first hollow shell 3, the vertical support rods 8 are stably placed in the first storage slot 6, and the horizontal railings 9 are hidden in the second storage slot 7. The entire splicing frame occupies little space, making it easy to transport and store, reducing space costs and handling difficulty. When in use, first operate the rotating support assembly, and the U-shaped crossbeams 5 gradually unfold to a horizontal position, quickly building the basic shape of the frame to prepare for subsequent support. After the frame is formed, the vertical support rods 8 are removed from the first storage slot 6. The vertical support rods 8 are connected to the base plate 1 through a hinge point, allowing them to rotate smoothly around this point on the base plate 1 when removed. As it rotates, the vertical support rod 8 continuously adjusts its angle. When it reaches the appropriate position, it can stably support the horizontal U-shaped beam 5, greatly enhancing the vertical load-bearing capacity of the splicing frame and ensuring its stability. During the rotation and removal of the vertical support rod 8, it is connected to the horizontal railing 9 by a rotating pin. The rotation of the vertical support rod 8 generates tension through the rotating pin, pulling the horizontal railing 9 out of the second storage slot 7. After being pulled out, the horizontal railing 9 is quickly adjusted to the appropriate position, spanning the horizontal area of ​​the splicing frame, forming an effective lateral interception to prevent items from sliding or shifting laterally, thus improving the protective and load-bearing functions of the splicing frame.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
