Description

Technical Field

[0001] This invention belongs to the field of shelving technology, specifically an adjustable display screen transfer shelf. Background Technology

[0002] In the manufacturing process of displays, relying entirely on manual handling is time-consuming and labor-intensive, and a single transfer rack cannot support the use of multiple display models. To address these shortcomings, this patented adjustable display transfer rack, due to its adjustability, can accommodate various display models; by adjusting the size of the rack, it can support different display models, thus expanding its adaptability.

[0003] This patented transfer rack can be used for displays of different models and sizes. This adjustable display transfer rack is more conducive to improving production efficiency during use.

[0004] However, during the assembly and transportation of conventional display screens, the screens need to be placed on transfer racks. Existing racks have fixed space and can only accommodate screens of a single size. If the size of the product being transported varies greatly, multiple special racks need to be purchased. Moreover, the racks are not equipped with adjustable limit structures. During transportation, the display screen is easily moved and shaken due to bumps, and the screen may collide with the support, significantly increasing the risk of scratches, cracks, and other damage. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable display screen transfer rack to solve the problems mentioned above regarding the ease of adjusting the working size and the provision of a display screen transfer rack with auxiliary limiting components.

[0006] The technical solution adopted in this invention is as follows: an adjustable display screen transfer shelf includes a column, a bracket size adjustment component is provided on the side of the column, a plurality of support columns are provided at adjacent positions of the column, a display screen limiting component is fixedly connected to the middle position of the column and the bracket size adjustment component and the middle position of the adjacent bracket size adjustment component, and a roller limiting component is provided on the side of the column and the support columns.

[0007] In a preferred embodiment, the bracket size adjustment assembly includes a first mounting rod, a first telescopic rod, a first button, a second telescopic rod, a second button, a second mounting rod, a first slide groove, a first spring, a second spring, a second slide groove, and a third telescopic rod;

[0008] Multiple first mounting rods and second mounting rods are fixedly installed on the side of the column. The second mounting rod is located at the upper end of the first mounting rod. A telescopic rod, including a first telescopic rod and a third telescopic rod, is slidably connected to the side of the first mounting rod. Multiple first through holes are provided on the side of the first mounting rod adjacent to the first telescopic rod. Multiple first sliding grooves are provided on the side of the first telescopic rod and the third telescopic rod. A first button is slidably connected to the side of the first sliding groove. A first spring is fixedly connected to the side of the first button. The other end of the first spring is fixedly connected to the first sliding groove. The first button is engaged in the first through hole.

[0009] The second mounting rod is slidably connected to a second telescopic rod on its side. Multiple second through holes are provided at both the upper and lower ends of the second mounting rod. Multiple second sliding grooves are provided at both the upper and lower ends of the second telescopic rod. A second button is slidably connected to the upper end of the second sliding groove. A second spring is fixedly connected to the lower end of the second button. The other end of the second spring is fixedly connected to the second sliding groove. The second button is engaged in the second through hole. A display screen is provided at the middle position of the adjacent third telescopic rod.

[0010] By adopting the above technical solution, the first button is used in conjunction with the adjustment of the first and third telescopic rods, the second mounting rod is used in conjunction with the adjustment of the second telescopic rod, and the length of the structure is adjusted accordingly. This adapts to the placement of displays of different lengths and sizes. The first button restricts the positions of the first and third telescopic rods within the first mounting rod, and the second button restricts the position of the second telescopic rod within the second mounting rod. The first slide groove is used in conjunction with the installation of the first button and the first spring. The operator inserts the first telescopic rod into the first mounting rod and compresses the first button by pressing it. The first slide groove facilitates the installation of the first telescopic rod. When the first button moves into the first through hole in the first mounting rod, the first spring pushes the first button out of the first slide groove and then engages it in the corresponding first through hole. If a secondary adjustment is needed, the operator can press the first button again to engage it in the first through hole at different positions. Similarly, the second slide groove works with the second spring and the second button to facilitate the adjustment of the position of the second telescopic rod in the second mounting rod. The second spring drives the second button to move in the second slide groove, making it easy to engage the second button in the second through hole at different positions, which is convenient for adjusting the length of the structure.

[0011] This structure allows for adjustment of the shelf size to accommodate production needs of displays of different sizes. It is convenient and stable to use, and the shelf's functionality is not affected by the size of the display screen.

[0012] In a preferred embodiment, the display screen limiting assembly includes a rectangular plate, a rotating handle, a fixing bolt, a sliding block, a limiting plate, a rubber plate, a threaded rod, a first gear, a second gear, and an inner connecting rod.

[0013] The rectangular plate is fixedly installed between the column and the support column, and at the middle position between two adjacent support columns. The rectangular plate has a threaded rod inside, and a rotating handle is rotatably connected to the side of the rectangular plate. The other end of the rotating handle is fixedly connected to an inner connecting rod inside the rectangular plate. A first gear is fixedly connected to the side of the inner connecting rod. The first gear meshes with a second gear. The other end of the threaded rod is fixedly connected to the second gear.

[0014] The threaded rod has multiple sliding blocks threadedly connected to its side. A limit plate is fixedly connected to the side of each sliding block. A rubber plate is fixedly connected to the side of each limit plate. A fixing bolt is threadedly connected to the side of each sliding block. The other end of the fixing bolt passes through the sliding block and abuts against the threaded rod.

[0015] By adopting the above technical solution, multiple limiting plates are used in conjunction with the display screen for limiting operations. The length of the structure can be adjusted to accommodate display screens of different sizes, and the position of the limiting plates can be adjusted to accommodate the width of the display screen, preventing the display screen from swaying left and right during transfer and reducing the risk of damage. The threaded rod, in conjunction with the adjustment of the limiting plates, facilitates subsequent transfer and transportation. Rotating the handle drives the inner connecting rod and the first gear, which in turn drives the second gear. The rotation of the second gear adjusts the position of the sliding block. Before adjustment, the fixing bolts are loosened to allow workers to adjust the position of adjacent sliding blocks, moving the limiting plate closer to the display screen. The rubber plate reduces rigid contact between the structures, preventing accidental damage to the display screen and facilitating subsequent operations.

[0016] In a preferred embodiment, the roller shaft limiting assembly includes an outer roller shaft, a limiting bolt, an inner connecting rod, a limiting toothed plate, and a rotating disk;

[0017] The outer roller shaft is assembled in the middle area between the column and the support column, and between adjacent support columns. Limit bolts are provided on the sides of the column and the support column. An inner connecting rod is rotatably connected to the side of the outer roller shaft. A rotating disk is fixedly connected to the side of the inner connecting rod inside the column. A limit tooth plate is opened inside the rotating disk. The other end of the limit bolt passes through the column and is engaged with the outer end of the limit tooth plate.

[0018] By adopting the above technical solution, the outer roller shaft cooperates with the first roller shaft and the second roller shaft to form a bearing and conveying surface. Before use, the operator tightens the limiting bolts so that the other end of the limiting bolts is engaged in the limiting tooth plate set in the rotating disk, thereby restricting the rotation of the rotating disk. The outer roller shaft is connected to the rotating disk through the inner connecting rod, thereby restricting the rotation of the outer roller shaft and restricting the movement of the display screen at the upper end of the outer roller shaft. When used in conjunction with the subsequently set stop bar, it ensures that the display screen is placed stably in the structure. After loosening the limiting bolts, the rotating disk can rotate freely, and the outer roller shaft cooperates with the first and second roller shafts to roll, making it convenient for the operator to push the display screen in.

[0019] In a preferred embodiment, the lower end of the column is fixedly connected to a self-locking caster wheel.

[0020] By adopting the above technical solution, the self-locking universal wheel and its structure can be used for positional movement operations to meet the transfer needs of different positions.

[0021] In a preferred embodiment, connecting rods are fixed between the upright and the support column, between adjacent support columns, and below the outer roller shaft.

[0022] By adopting the above technical solution, the connecting rod is used to strengthen the connection between each column and support column, thereby improving the overall structural stability of the frame.

[0023] In a preferred embodiment, a slot frame is fixedly connected to the side of the column, and multiple stops are provided on the side of the slot frame, including a rear rail and a rear rail, and a nut is threadedly connected to the side of the rear rail.

[0024] By adopting the above technical solution, multiple sets of stop bars are used to constrain the front and rear positions of the display screen, and the nut limits the position of the rear railing, which facilitates the installation of the rear railing.

[0025] In a preferred embodiment, a plurality of first rollers are provided at the midpoint between the column and the support column, adjacent to the outer roller shaft.

[0026] By adopting the above technical solution, the first roller shaft is used in conjunction with the second roller shaft, which facilitates the placement of the display screen.

[0027] In a preferred embodiment, the third telescopic rod has a plurality of mounting through holes on its side, a second roller is provided at the middle position of adjacent third telescopic rods, a side connecting ring plate is fixedly connected to the side of the second roller, a locking post is slidably connected to the side of the side connecting ring plate, the locking post is engaged in the mounting through hole, a third spring is fixedly connected to the side of the locking post, and the other end of the third spring is fixedly connected to the side connecting ring plate.

[0028] By adopting the above technical solution, the installation through hole facilitates the installation of the second roller shaft. The operator presses the locking post from the side, causing the locking post to retract towards the inside of the side connecting ring plate, making it easy to engage the locking post into the installation through hole. This facilitates the installation and disassembly of the second roller shaft. The design of this structure allows for adjustment of the number of second roller shafts according to the length of the third telescopic rod, adapting to the load-bearing requirements of different display screen specifications.

[0029] In a preferred embodiment, the display screen is placed on the upper end of the outer roller shaft, the first roller shaft, and the second roller shaft. A handle is fixedly connected to the side of the column adjacent to the slot frame. The first spring, the second spring, and the third spring are all standard chrome vanadium steel springs.

[0030] By adopting the above technical solution, the display screen is placed inside the frame, which facilitates subsequent transfer and transportation operations and makes it easier to use in subsequent transfer operations. The handle is used by the staff to move the structure, and the spring made of chrome vanadium steel has high resilience and structural strength, and is not easy to fail after long-term adjustment.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] In this invention, the overall length of the shelf can be flexibly adjusted by using a first button, a first telescopic rod, and a third telescopic rod in conjunction with a second mounting rod and a second telescopic rod, adapting to the placement of displays of different lengths. The first slide provides installation and movement space for the first button and the first spring. When the operator presses the first button, it can be pressed into the slide, facilitating the insertion of the telescopic rod into the first mounting rod. When the button aligns with the first through hole, the first spring pushes it out and engages it in the through hole, completing the positioning and fixing. Pressing the button again switches the engagement position, adjusting the telescopic rod's extension length. The second slide, the second spring, and the second button work together to lock the extension position of the second telescopic rod. The double-layer adjustment structure is easy to operate, effectively overcoming the limitations of display screen size and significantly improving the shelf's adaptability and practicality.

[0033] The display screen limiting components precisely limit the width of the display screen, effectively preventing it from shaking or being damaged during transfer. Turning the handle drives the inner connecting rod and the first gear, which in turn drives the second gear and the threaded rod to rotate synchronously. Loosening the fixing bolts before adjustment allows the sliding block and the limiting plate to move laterally, fitting the side of the display screen and adapting to different widths. The rubber plate inside the limiting plate cushions the rigid contact with the structure, preventing scratches from rigid compression. After adjustment, tightening the fixing bolts locks the entire limiting structure, ensuring stability and providing reliable protection for the transfer and transport of the display screen.

[0034] The outer roller shaft, the first roller shaft, and the second roller shaft work together to form a dedicated load-bearing and conveying structure for the display screen, simultaneously meeting the requirements for stable support and convenient loading and unloading. When the equipment is stored statically, tightening the limit bolts causes their ends to engage with the rotating disk limit structure, locking the rotational freedom of the rotating disk and the outer roller shaft. Combined with the stop bar structure, the display screen can be firmly fixed to prevent displacement and shaking. When loading and unloading materials, loosening the limit bolts releases the lock, allowing each roller shaft to roll freely, effectively reducing the frictional resistance during the pushing and pulling of the display screen, enabling workers to quickly complete the storage and retrieval of the display screen, and significantly improving the overall efficiency of the transfer operation.

[0051] Multiple first mounting rods 301 and second mounting rods 306 are fixedly installed on the side of the column 1. The second mounting rod 306 is located at the upper end of the first mounting rod 301. The side of the first mounting rod 301 is slidably connected to a telescopic rod, including a first telescopic rod 302 and a third telescopic rod 311. Multiple first through holes are provided on the side of the first mounting rod 301 adjacent to the first telescopic rod 302. Multiple first sliding grooves 307 are provided on the side of the first telescopic rod 302 and the third telescopic rod 311. A first button 303 is slidably connected to the side of the first sliding groove 307. A first spring 308 is fixedly connected to the side of the first button 303. The other end of the first spring 308 is fixedly connected to the first sliding groove 307. The first button 303 is snapped into the first through hole.

A display screen is provided at the midpoint between adjacent third telescopic rods 311. 9. The first button 303 is used in conjunction with the adjustment of the first telescopic rod 302 and the third telescopic rod 311, and the second mounting rod 306 is used in conjunction with the adjustment of the second telescopic rod 304. This is used for adjusting the length of the structure and adapting to the placement of displays 9 of different lengths and sizes. The first button 303 restricts the position of the first telescopic rod 302 and the third telescopic rod 311 within the first mounting rod 301, and the second button 305 restricts the second telescopic rod 304 within the second mounting rod 306. The first groove 307 is positioned within the first mounting rod 301 and is designed to facilitate the installation of the first button 303 and the first spring 308. The operator inserts the first telescopic rod 302 into the first mounting rod 301 and presses the first button 303, compressing it into the first groove 307. This facilitates the installation of the first telescopic rod 302. When the first button 303 moves into the first through hole within the first mounting rod 301, the first spring 308 pushes the first button 303 out of the first groove 307, and then it engages with the corresponding... When secondary adjustment is required in the first through hole, the operator can press the first button 303 again to make the first button 303 engage in the first through hole at different positions. Similarly, the second slide groove 310 works with the second spring 309 and the second button 305 to facilitate the adjustment of the position of the second telescopic rod 304 in the second mounting rod 306. The second spring 309 drives the second button 305 to move in the second slide groove 310, making it easy to engage the second button 305 in the second through hole at different positions, which is convenient for adjusting the length of the structure.

[0053] This structure allows for adjustment of the shelf size to accommodate production needs of displays of different sizes. It is convenient and stable to use, and the shelf's functionality is not affected by the size of the display screen.

[0054] Reference Figure 1-3 The display screen limiting assembly 4 includes a rectangular plate 401, a rotating handle 402, a fixing bolt 403, a sliding block 404, a limiting plate 405, a rubber plate 406, a threaded rod 407, a first gear 408, a second gear 409, and an inner connecting rod 410.

[0055] The rectangular plate 401 is fixedly installed between the column 1 and the support column 8, and at the middle position between two adjacent support columns 8. The rectangular plate 401 is provided with a threaded rod 407 inside. The side of the rectangular plate 401 is rotatably connected to a rotating handle 402. The other end of the rotating handle 402 is located inside the rectangular plate 401 and is fixedly connected to an inner connecting rod 410. The side of the inner connecting rod 410 is fixedly connected to a first gear 408. The first gear 408 is meshed with a second gear 409. The other end of the threaded rod 407 is fixedly connected to the second gear 409.

[0056] Multiple sliding blocks 404 are threadedly connected to the side of the threaded rod 407. A limit plate 405 is fixedly connected to the side of each sliding block 404. A rubber plate 406 is fixedly connected to the side of the limit plate 405. A fixing bolt 403 is threadedly connected to the side of each sliding block 404. The other end of the fixing bolt 403 passes through the sliding block 404 and abuts against the threaded rod 407. The multiple limit plates 405 work in conjunction with the limiting operation of the display screen 9. By adjusting the length of the structure, it can adapt to different sizes of display screens 9. By adjusting the position of the limit plates 405, it can adapt to the width of the display screen 9, preventing the display screen 9 from wobbling left and right during transfer and reducing the risk of damage. The threaded rod 407 is used in conjunction with the limiting plate 405 for adjustment, which facilitates subsequent transfer and transportation. By rotating the rotating handle 402, the inner connecting rod 410 and the first gear 408 are rotated, which in turn drives the second gear 409 to rotate. The rotation of the second gear 409 adjusts the position of the sliding block 404. Before adjustment, the fixing bolt 403 is loosened to facilitate the adjustment of the position of the adjacent sliding block 404 by the operator, which drives the position of the limiting plate 405 to move so that the limiting plate 405 is close to the display screen 9. The rubber plate 406 reduces the hard contact between the structures and prevents accidental damage to the display screen 9, which is conducive to subsequent operation.

The outer roller shaft 501, together with the first roller shaft 13 and the second roller shaft 14, forms a bearing and conveying surface. Before use, the operator... Tighten the limiting bolt 502 so that the other end of the limiting bolt 502 is engaged in the limiting toothed plate 504 set in the rotating disk 505, thereby restricting the rotation of the rotating disk 505. The outer roller shaft 501 is connected to the rotating disk 505 through the inner connecting rod 503, thereby restricting the rotation of the outer roller shaft 501 and restricting the movement of the display screen 9 at the upper end of the outer roller shaft 501. This is used in conjunction with the stop bar set later to ensure that the display screen 9 is placed stably in the structure. After loosening the limiting bolt 502, the rotating disk 505 can rotate freely, and the outer roller shaft 501 rolls in conjunction with the first and second roller shafts, making it convenient for the staff to push the display screen 9 in.

[0059] Reference Figure 1 The lower end of the column 1 is fixedly connected to a self-locking caster 2. The self-locking caster 2 is used to move the structure in conjunction with the structure to meet the transfer needs of different positions.

[0060] Reference Figure 1 Connecting rods 6 are fixed between the upright column 1 and the support column 8, between adjacent support columns, and below the outer roller shaft 501. The connecting rods 6 are used to reinforce the connection between each upright column and support column and improve the overall stability of the frame structure.

[0061] Reference Figure 1 The side of the column 1 is fixedly connected to the slot frame 10. The side of the slot frame 10 is provided with multiple stops, including the rear rail 7 and the rear rail 12. The side of the rear rail 12 is threadedly connected with a nut 11. The multiple stops are used to constrain the front and rear position of the display screen 9. The nut 11 limits the position of the rear rail 12, which facilitates the installation of the rear rail 12.

[0062] Reference Figure 1 Multiple first rollers 13 are provided at the middle position of the column 1 and the support column 8, adjacent to the outer roller 501. The first rollers 13 are used in conjunction with the second rollers 14 to facilitate the placement of the display screen 9.

[0063] Reference Figure 1 , Figure 6The third telescopic rod 311 has multiple mounting through holes on its side. A second roller 14 is located in the middle of adjacent third telescopic rods 311. A side connecting ring plate 16 is fixedly connected to the side of the second roller 14. A locking post 18 is slidably connected to the side of the side connecting ring plate 16. The locking post 18 is engaged in the mounting through hole. A third spring 17 is fixedly connected to the side of the locking post 18. The other end of the third spring 17 is fixedly connected to the side connecting ring plate 16. The mounting through holes facilitate the installation of the second roller 14. The operator presses the locking post 18 from the side, causing the locking post 18 to retract inward to the side connecting ring plate 16, making it easy to engage the locking post 18 in the mounting through hole. This facilitates the installation and disassembly of the second roller 14. This structure allows for adjustment of the number of second rollers 14 according to the length of the third telescopic rod 311, adapting to the load-bearing requirements of different specifications of display screens 9.

[0064] Reference Figure 1 , Figure 7 The display screen 9 is placed on the upper end of the outer roller shaft 501, the first roller shaft 13 and the second roller shaft 14. The side of the column 1 is fixedly connected to the handle 15 at the adjacent position of the slot frame 10. The first spring 308, the second spring 309 and the third spring 17 are all standard chrome vanadium steel springs. The display screen 9 is placed in the frame to facilitate subsequent transfer and transportation operations. The handle 15 is used by the staff to move the structure. The chrome vanadium steel springs have high resilience and structural strength and are not easy to fail after long-term adjustment.

[0065] The implementation principle of an embodiment of the adjustable display screen transfer shelf of the present invention is as follows:

[0066] The first button 303 is used in conjunction with the adjustment of the first telescopic rod 302 and the third telescopic rod 311. The second mounting rod 306 is used in conjunction with the adjustment of the second telescopic rod 304. This is used for length adjustment of the structure and to accommodate the placement of displays 9 of different lengths and sizes. The first button 303 restricts the positions of the first telescopic rod 302 and the third telescopic rod 311 within the first mounting rod 301. The second button 305 restricts the position of the second telescopic rod 304 within the second mounting rod 306. The first slide groove 307 is used in conjunction with the installation of the first button 303 and the first spring 308. The operator inserts the first telescopic rod 302 into the first mounting rod 301 and presses the first button 303, compressing it into the first slide groove. Within 307, the installation of the first telescopic rod 302 is convenient. When the first button 303 moves into the first through hole in the first mounting rod 301, the first spring 308 pushes the first button 303 out of the first slide groove 307 and then engages it in the corresponding first through hole. When a secondary adjustment is needed, the operator can press the first button 303 again to engage it in the first through hole at different positions. Similarly, the second slide groove 310 works with the second spring 309 and the second button 305 to facilitate the adjustment of the position of the second telescopic rod 304 in the second mounting rod 306. The second spring 309 drives the second button 305 to move within the second slide groove 310, making it easy to engage the second button 305 in the second through hole at different positions, thus facilitating the adjustment of the length of the structure.

[0067] Multiple limiting plates 405 are used in conjunction with the display screen 9 for limiting operations. The length of the structure can be adjusted to accommodate different sizes of display screens 9, and the position of the limiting plates 405 can be adjusted to accommodate the width of the display screen 9, preventing the display screen 9 from swaying left and right during transfer and reducing the risk of damage. The threaded rod 407 is used in conjunction with the adjustment of the limiting plates 405 to facilitate subsequent transfer and transportation. Rotating the handle 402 drives the inner connecting rod 410 and the first gear 408 to rotate, thereby driving the second gear 409 to rotate. The rotation of the second gear 409 adjusts the position of the sliding block 404. Before adjustment, the fixing bolt 403 is loosened to facilitate the adjustment of the position of adjacent sliding blocks 404 by the operator, which drives the position of the limiting plate 405 to move closer to the display screen 9. The rubber plate 406 reduces the hard contact between the structures to prevent accidental damage to the display screen 9 and facilitates subsequent operations.

[0068] The outer roller shaft 501, together with the first roller shaft 13 and the second roller shaft 14, forms a bearing and conveying surface. Before use, the operator tightens the limiting bolt 502 so that the other end of the limiting bolt 502 is engaged in the limiting tooth plate 504 set in the rotating disk 505, thereby restricting the rotation of the rotating disk 505. The outer roller shaft 501 is connected to the rotating disk 505 through the inner connecting rod 503, thereby restricting the rotation of the outer roller shaft 501 and restricting the movement of the display screen 9 at the upper end of the outer roller shaft 501. This is used in conjunction with the stop bar set later to ensure that the display screen 9 is placed stably in the structure. After loosening the limiting bolt 502, the rotating disk 505 can rotate freely, and the outer roller shaft 501 rolls in conjunction with the first and second roller shafts, making it convenient for the operator to push the display screen 9 in.
