Abstract
Description
Technical Field
[0001] This utility model relates to the field of tin-plated sheet technology, specifically a foldable tin-plated sheet transport rack. Background Technology
[0002] In industries such as metal processing and packaging, tinplate is widely used in food packaging, chemical containers, and electronic component housings due to its excellent corrosion resistance, formability, and surface decoration. As the production scale of tinplate expands and market demand grows, the efficiency and cost control of its transportation process are receiving increasing attention from enterprises.
[0003] Currently, the industry commonly uses fixed transport racks to carry and transport tinplate. In order to meet the load-bearing stability requirements of tinplate, especially rolled tinplate, these transport racks are usually designed as an integrated rigid structure, and their size and volume must be adapted to the specifications of the tinplate to be transported.
[0004] However, in the actual transportation process, after the transport rack has completed the task of delivering the tin-plated sheet, it needs to return empty for recycling. At this time, because its structure cannot be retracted or folded, the transport rack in the empty state still maintains a volume that is basically the same as when it is fully loaded, resulting in extremely low space utilization during the return transportation process.
[0005] In view of the above, this application is hereby submitted. Utility Model Content
[0006] The purpose of this invention is to provide a foldable tin-plated sheet transport rack to solve the problems mentioned in the background art.
[0007] To solve the above technical problems, the present invention provides a foldable tin-plated sheet transport rack, including a base plate, a top plate, a folding assembly and a locking shaft. The folding assembly is fixedly installed on the top side of the base plate, and the top of the folding assembly is fixedly connected to the top plate. The folding assembly includes a connecting block, a connecting rod, a first long rod, and a second long rod. The connecting block is fixedly connected to the top of the base plate. Two connecting rods are rotatably installed on the top of the connecting block. The ends of the two connecting rods are respectively rotatably installed with the first long rod and the second long rod. The first long rod and the second long rod are arranged to cross each other and are connected by a locking shaft at the intersection. Another connecting rod is rotatably installed on the top of each of the first long rod and the second long rod. Another connecting block is rotatably installed on the top of the other connecting rod. The top of the other connecting block is fixedly connected to the top plate.
[0008] Furthermore, it also includes a mid-section limiting frame, which includes a fixing plate and a tension band. The fixing plate is fixedly installed between the bottom plate and the top plate. One end of the tension band is fixedly connected to the fixing plate, and the other end is fixedly connected to the folding assembly. The connection point between the tension band and the folding assembly is located at the intersection area of long rod one and long rod two. The fixing plate maintains a preset distance from both the bottom plate and the top plate.
[0009] Furthermore, both ends of the X-block are arc-shaped structures, and the protrusions of the rear fork and front fork are smaller than the groove size of the X-block.
[0010] Furthermore, the locking shaft includes a turntable, a fixed plate, and a rotating rod. The turntable is fixedly connected to the center of a long rod, the rotating rod is fixedly installed at the center of the turntable, the fixed plate is rotatably installed on the outer wall of the rotating rod, and the outer wall of the fixed plate is fixedly connected to the center of a long rod. A sliding groove is provided on the inner edge of the turntable, a rear fork is provided at one end of the sliding groove, and a front fork is provided at the side end of the sliding groove. The rear fork and the front fork are both integral with the turntable. A plug rod is fixedly installed on the side of the fixed plate near the turntable, and an X-block is rotatably installed on the outer wall of the plug rod. The X-block is slidably installed on the inner wall of the sliding groove.
[0011] Furthermore, the connecting block is fixedly connected to the bottom plate and the top plate by bolts, and the connecting rod is rotatably connected to the connecting block, long rod one, and long rod two by pins, with anti-detachment washers provided at both ends of the pins.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By using the cross rotation of long rod one and long rod two in the folding assembly in conjunction with the locking and unlocking function of the locking shaft, the transport frame can be retracted and folded when returning empty, with the top plate close to the bottom plate, which greatly reduces the overall volume, improves the space utilization rate of return transport, avoids the space waste caused by the fixed volume of traditional fixed transport frames when empty, and reduces transportation costs. 2. During transportation, the locking function of the locking shaft, together with the tension band in the middle limit frame, provides auxiliary constraint on the folding assembly, ensuring that the folding assembly maintains rigid support, reducing shaking, and ensuring the stability of the tin-plated sheet during transportation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-4 This utility model provides a technical solution: a foldable tin-plated sheet transport rack, including a base plate 1, a top plate 2, a folding assembly 3, and a locking shaft 5. The folding assembly 3 is fixedly installed on the top side of the base plate 1, and the top of the folding assembly 3 is fixedly connected to the top plate 2. The folding assembly 3 is composed of a connecting block 31, a connecting rod 32, a first long rod 33, and a second long rod 34. Through the linkage of the cross-arranged first long rod 33 and second long rod 34 at the locking shaft 5, the lifting and folding of the transport rack are integrated. After folding, the volume is greatly reduced, improving the space utilization rate of the empty return trip and reducing transportation costs. At the same time, the various components form a stable support through fixed and rotating connections. To ensure the safety of the tin-plated sheet during transportation, the folding assembly 3 includes a connecting block 31, a connecting rod 32, a first long rod 33, and a second long rod 34. The connecting block 31 is fixedly connected to the top of the base plate 1. Two connecting rods 32 are rotatably installed on the top of the connecting block 31. The ends of the two connecting rods 32 are respectively rotatably installed with the first long rod 33 and the second long rod 34.

Another connecting block 31 is rotatably installed on the top of the other connecting rod 32. The top of the other connecting block 31 is fixedly connected to the top plate 2.
[0017] Please see Figures 1-4This utility model provides a technical solution: a foldable tin-plated sheet transport rack, including a locking shaft 5, a turntable 51, a fixed plate 52, and a rotating rod 53. The turntable 51 is fixedly connected to the center of a first long rod 33, and the rotating rod 53 is fixedly installed at the center of the turntable 51. The fixed plate 52 is rotatably installed on the outer wall of the rotating rod 53, allowing the two to rotate relative to each other. The outer wall of the fixed plate 52 is fixedly connected to the center of a second long rod 34, and the fixed plate 52 is fixed to the second long rod 34, ensuring that the cross rotation of the first long rod 33 and the second long rod 34 is synchronized and linked, avoiding misalignment and improving the smoothness of folding and lifting.
[0018] Please see Figures 1-4 This utility model provides a technical solution: a foldable tin-plated sheet transport rack, including a slide groove 511 on the inner edge of a turntable 51, a slide groove 511 and an integrally formed rear fork 512 and front fork 513 on the inner wall of the turntable 51, providing a precise movement path and limiting fulcrum for the locking structure, the slide groove 511 guides the X-block 522 to slide in a directional manner, a rear fork 512 is provided at one end of the slide groove 511, and a front fork 513 is provided at the side end of the slide groove 511, the rear fork 512 and the front fork 513 are locked by mechanical engagement, and both the rear fork 512 and the front fork 513 are integrally formed with the turntable 51.
[0019] Please see Figures 1-4 This utility model provides a technical solution: a foldable tin-plated sheet transport rack, including a fixed plate 52 with a rod 521 fixedly installed on one side near the turntable 51. A rotatable X-block 522 is installed on the rod 521 on the fixed plate 52. The X-block 522 is rotatably installed on the outer wall of the rod 521. The X-block 522 is slidably installed on the inner wall of the slide groove 511 and is slidably engaged in the slide groove 511 to form a dynamic locking and unlocking mechanism. The rotational characteristics of the X-block 522 enable it to adapt to the trajectory of the slide groove 511. With the cooperation of the rear fork 512 and the front fork 513, it can achieve multi-position locking, which not only ensures the reliability of the height of the top plate 2, but also provides a smooth unlocking path for the folding action, improving the convenience of operation.
[0020] Please see Figures 1-4 This utility model provides a technical solution: a foldable tin-plated sheet transport rack, which also includes a middle section limiting frame 4. The middle section limiting frame 4 includes a fixing plate 41 and a tension belt 42. Through the cooperation of the fixing plate 41 and the tension belt 42, additional support is provided for the folding assembly 3. The fixing plate 41 is fixedly installed between the bottom plate 1 and the top plate 2. One end of the tension belt 42 is fixedly connected to the fixing plate 41, and the other end is fixedly connected to the folding assembly 3. The tension belt 42 connects the folding assembly 3 and the fixing plate 41, and buffers the shaking of the folding assembly 3 during lifting and transportation.
[0021] Please see Figures 1-4This utility model provides a technical solution: a foldable tin-plated sheet transport rack, including a tension belt 42 whose connection point with the folding component 3 is located at the intersection of long rod 1 33 and long rod 2 34, so that the constraint force of the tension belt 42 directly acts on the core force area of the folding component 3, enhancing the limiting effect. The fixed plate 41 and the bottom plate 1 and top plate 2 maintain a preset distance. The preset distance ensures that the tension belt 42 can maintain appropriate tension in both folded and unfolded states, avoiding excessive looseness or tightness that would affect the operation of the device.
[0022] Please see Figures 1-4 This utility model provides a technical solution: a foldable tin-plated sheet transport rack, including a connecting block 31 that is fixedly connected to the bottom plate 1 and the top plate 2 by bolts. The bolt fixing ensures that the connecting block 31 is firmly installed and adapts to the vibration environment during transportation. The connecting rod 32 is rotatably connected to the connecting block 31, the first long rod 33, and the second long rod 34 by pins. The pin rotatable connection reduces friction between components and improves folding flexibility. Anti-detachment pads are provided at both ends of the pins.
[0023] Please see Figures 1-4 This utility model provides a technical solution: a foldable tin-plated sheet transport rack, including an X-block 522 with both ends having arc structures. The arc structures reduce the impact wear between the X-block 522 and the slide groove 511, rear fork 512, and front fork 513, extending the service life of the components. The protrusions of the rear fork 512 and front fork 513 are smaller than the groove size of the X-block 522.
[0024] Working principle: First, pull up the top plate 2, which drives the top connecting block 31 and connecting rod 32 to move, forcing the first long rod 33 and the second long rod 34 to rotate in opposite directions around the locking shaft 5, increasing the crossing angle. At this time, the turntable 51 of the locking shaft 5 rotates with the first long rod 33, and the fixed plate 52 rotates in the opposite direction with the second long rod 34. The X-block 522 slides along the slide groove 511 of the turntable 51 and hits the rear fork 512. After a brief engagement, it continues to slide under continuous tension until the height of the top plate 2 is aligned with the top of the roll of tin-plated sheet to be transported. Release the top plate 2, and its own weight causes the crossing angle of the first long rod 33 and the second long rod 34 to decrease. The X-block 522 engages with the front fork 513, and the locking shaft 5 is locked. The tension band 42 of the middle limit frame 4 forms an auxiliary constraint on the folding assembly 3, ensuring that the height of the top plate 2 is fixed, which facilitates the stable placement and transportation of the tin-plated sheet. After loading, the folding assembly 3 maintains rigid support under the locking shaft 5, and the tension band 42 further restrains the shaking, ensuring stable transportation. After unloading, the transport frame is empty. Pulling the top plate 2 upwards again increases the intersection angle of long rod 1 33 and long rod 2 34. The X-block 522 disengages from the front fork 513, impacts the rear fork 512, and is compressed and reset, unlocking the locking shaft 5. The top plate 2 is released. Under its own weight and the contraction force of the tension belt 42, the intersection angle of long rod 1 33 and long rod 2 34 continues to decrease. The folding assembly 3 retracts, and the top plate 2 moves closer to the bottom plate 1. The overall volume of the transport frame is significantly reduced, improving the space utilization rate for return transport.
