Description

Technical Field

[0001] This utility model relates to the field of office supplies technology, and in particular to a rotatable worktable. Background Technology

[0002] A workbench is a piece of furniture or equipment with multiple functions and uses. It is widely used in various places such as computer rooms, laboratories, and monitoring centers. Through reasonable design and layout, a workbench can provide operators with a comfortable and convenient working environment to improve their work efficiency.

[0003] Existing control panels are usually integrated or assembled structures. Such structures are usually fixed in use, so the actual footprint of the control panel is usually large, and it is difficult to adjust the shape of the control panel according to the actual needs of use. This results in a lack of flexibility in the use of the control panel and poor practical performance of the device.

[0004] On the other hand, adjustable workbenches typically consist of an upper table and a lower table. The upper table is usually rotatably mounted on the lower table, allowing the upper table to be stacked on top of the lower table when no additional usable space is required, thus reducing the actual floor space occupied by the workbench. However, the maximum usable area provided by the upper and lower table panels, which are installed by rotatable connection, is usually L-shaped or straight. Furthermore, the load-bearing surfaces of the adjusted upper and lower table panels are not at the same height. When engineering drawings need to be laid on the workbench for drawing or modification, the inconsistent height of the upper and lower table panels makes it difficult for operators to draw or modify the engineering drawings, resulting in poor actual performance of the device.

[0005] Furthermore, if an L-shaped or straight-line adjustable workbench is used to lay out A1 or A0 size engineering drawings, it is usually necessary to adjust the workbench to a straight line so that the A1 or A0 size engineering drawings can be laid out on the workbench. Since the actual size of A1 or A0 engineering drawings is 594mm x 841mm and 841mm x 1189mm, the width of the straight-line workbench usually needs to be equal to or greater than one meter in order to facilitate the operator to draw the engineering drawings. This leads to a further increase in the actual floor space occupied by the workbench, resulting in poor practicality of the device.

[0006] To address this issue, we designed a rotatable operating table to provide an alternative technical solution. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] Example 1

[0043] Reference Figure 1-8 A rotatable workbench includes a workbench body 1, a lower tabletop 2, and an upper tabletop 3. A storage cabinet 4 is provided on one side of the workbench body 1. The storage cabinet 4 contains multiple seats 5 for the operator to sit on. A cabinet door 6 is hinged to the outer side of the storage cabinet 4. Multiple tool storage boards 7 are provided on one side of the storage cabinet 4 for storing tools. The lower tabletop 2 is located at the top of the workbench body 1. The upper tabletop 3 is L-shaped and movably positioned above the lower tabletop 2. A rotating component is provided at the connection between the lower tabletop 2 and the upper tabletop 3 to facilitate the rotation of the upper tabletop 3.

[0044] Reference Figure 3-5The rotating assembly includes an inner bearing ring 8 and an outer bearing ring 9, which are respectively fixedly disposed on the opposite side of the lower table plate 2 and the upper table plate 3. The inner bearing ring 8 is connected to the outer bearing ring 9 through a rotating shaft. An annular groove 10 is provided on the opposite side of the outer bearing ring 9 and the annular groove 10 is embedded with a plurality of balls 11. A bearing retainer 12 is provided between the inner bearing ring 8 and the outer bearing ring 9 to fix and separate the balls 11. A plurality of foot brake casters 13 are fixedly disposed at the bottom of the upper table plate 3. Specifically, in this utility model, the design of the rotating assembly makes it easy for the operator to rotate and adjust the position of the upper table plate 3 according to different usage needs to meet different usage requirements. This maximizes the flexibility of the operation table without increasing the actual floor space occupied by the operation table, effectively improving the practical performance of the device. The design of the foot brake casters 13 makes it easy for the operator to fix the position of the upper table plate 3 after rotation, thereby ensuring the stability of the upper table plate 3 after adjustment.

[0045] In actual operation, the operator only needs to release the foot brake universal wheel 13, and then rotate the upper table 3 according to their own needs, so that the upper table 3 and the lower table 2 maintain different installation angles. After rotating the upper table 3 to the designated position, the operator only needs to step on the foot brake universal wheel 13 to fix the position of the upper table 3 after rotation.

[0046] Reference Figure 6-8The storage cabinet 4 has two partitions 14 fixedly installed at its top. Strip-shaped mounting plates 15 are fixedly installed on both sides of the two partitions 14. A pull-out cabinet 16 is slidably connected to the two strip-shaped mounting plates 15. Multiple sliders 17 are provided on the side of the pull-out cabinet 16 opposite to the strip-shaped mounting plates 15. Multiple ball bearings 18 are rotatably connected to the sliders 17. The strip-shaped mounting plates 15 have grooves 19 that match the sliders 17 and the ball bearings 18. Multiple ball bearings 20 are fixedly installed on the slider 17 located at the rear of the pull-out cabinet 16. The strip-shaped mounting plates 15 have limiting grooves 21 that match the ball bearings 20. The outer side of the pull-out cabinet 16 is fixedly provided with a mechanism to facilitate the operator's pulling out of the drawer. Specifically, in this utility model, the design of the partition 14, the strip-shaped mounting block, the drawer 16, and the handle 22 facilitates the storage of documents, data tables, and other items by the operator, thereby improving the practicality of this rotatable workbench. The design of the slider 17, the second ball bearing 18, the slide groove 19, the third ball bearing 20, and the limiting roller groove 21 enables the drawer 16 to slide and engage within the strip-shaped mounting block. This allows the operator to simply pull the handle 22 to remove documents or data tables from the drawer 16, causing the drawer 16 to slide on the strip-shaped mounting block. The operator can then stop pulling the handle 22 and remove the documents or data tables when the third ball bearing 20 comes into contact with the side wall of the limiting roller groove 21.

[0047] It should be noted that in this utility model, the design of ball bearing 11, ball bearing 28 and ball bearing 320 is all to reduce the motion resistance when the upper table 3 rotates and the drawer cabinet 16 slides, so as to make the process of the upper table 3 rotating and the drawer cabinet 16 sliding smoother and improve the actual use effect of the device.

[0048] Example 2

[0049] This embodiment is a further optimization based on Embodiment 1. In practical application, we have found that adjustable-shaped workbenches typically include an upper table and a lower table. The upper table is usually rotatably mounted on the lower table, so that when the workbench does not need to expand the actual usable space, the upper table can be stacked on top of the lower table to reduce the actual floor space occupied by the workbench. However, the maximum usable area provided by the upper table 3 and lower table 2, which are installed by rotatable connection, is usually L-shaped or straight. Moreover, the load-bearing surfaces of the upper and lower table are not at the same height after adjustment. When it is necessary to lay engineering drawings on the workbench for drawing or modification, the inconsistent height of the upper and lower tabletops is not conducive to the operator's drawing or modification of engineering drawings, and the actual use effect of the device is not good.

[0050] Reference Figure 9-10The lower table 2 is divided into a lower table first 221 and a lower table second 222. The lower table first 221 is fixedly mounted on the main body 1 of the operating table. The lower table second 222 is movably mounted on one side of the lower table first 221. Multiple adjusting screws 23 are rotatably connected to the bottom of the lower table second 222. The bottom of each adjusting screw 23 is threadedly connected to multiple partitions 14. Drive gears 24 are threadedly connected to the adjusting screws 23. Toothed belts 25 mesh with the outer surfaces of the multiple drive gears 24. A rotating sleeve 26 is fixedly connected to the bottom of each drive gear 24. A driven bevel gear 27 is fixedly connected to the bottom of one of the rotating sleeves 26. The bottom of the driven bevel gear 27 is fixed... A rotating sleeve 28 is connected, and the bottom ends of the other rotating sleeves 26 are rotatably connected to the partition plate 14. The driven bevel gear 27 is externally meshed with a driving bevel gear 29. A transmission shaft 30 is fixedly connected to the middle of the driving bevel gear 29. One end of the transmission shaft 30 passes through the main body of the operating table 1 and is connected to an adjustment knob 31. Specifically, in this utility model, the design of the lifting component makes it easy for the operator to adjust the height of the bearing surface of the lower table 2 so that the bearing surfaces of the upper table 3 and the lower table 2 after being adjusted in an L-shape or straight line can be at the same height, so that the operator can draw or modify the engineering drawings and improve the actual use effect of the device.

[0051] In actual operation, the operator only needs to rotate the upper table 3 to form an L-shape or a straight line with the lower table 2, fix the position of the upper table 3 after rotation, and then rotate the adjustment knob 31 to make the transmission shaft 30 drive the drive bevel gear 29 to rotate, thereby driving the driven bevel gear 27 meshing with it to rotate. At this time, the driven bevel gear 27 drives the drive gear 24 to rotate through the rotating sleeve 26, and drives multiple drive gears 24 to rotate synchronously through the toothed belt 25 sleeved on the outside of the drive gear 24. This causes the threaded rod connected to the thread in the middle of the drive gear 24 to lift the lower table 222 upward. When the lower table 222 and the bearing surface of the upper table 3 are at the same level, stop rotating the adjustment knob 31.

[0052] It should be noted that in this utility model, the driven bevel gear 27 has a through hole in the middle to facilitate the passage of the adjusting screw 23. Therefore, the driven bevel gear 27 does not have any connection with the adjusting screw 23, so as to ensure the normal operation of the lifting assembly.

[0053] Example 3

[0054] This embodiment is a further optimization based on Embodiment 2. During the actual use of the product in Embodiment 2, we found that if the worktable, which can be adjusted to an L-shape or a straight line, is used to lay out engineering drawings of size A1 or A0, it is usually necessary to adjust the worktable to a straight line so that the engineering drawings of size A1 or A0 can be laid out on the worktable. Since the actual size of A1 or A0 engineering drawings is 594mm x 841mm and 841mm x 1189mm, the width of the worktable in a straight line state usually needs to be equal to or greater than one meter in order to facilitate the operator to draw the engineering drawings. This leads to a further increase in the actual floor space occupied by the worktable, resulting in poor practicality of the device.

[0055] Reference Figure 11-16 The lower tabletop 2 and the upper tabletop 3 are provided with a desktop extension mechanism. The desktop extension mechanism includes a desktop telescopic component and a desktop support component. The desktop telescopic component includes a lower tabletop 222 spliced ​​together. The lower tabletop 222 is divided into a lower tabletop 32 and a lower tabletop 4. The lower tabletop 4 33 is slidably disposed on the lower tabletop 32. Sliding blocks 34 are fixedly connected to both sides of the lower tabletop 4 33. The lower tabletop 32 and the upper tabletop 3 are respectively provided with an L-shaped guide slider 35 and a U-shaped guide groove 36 that match the sliding blocks 34. An extension tabletop 37 is rotatably connected to the upper tabletop 3. A magnetic receiving strip 38 is provided on one side of the extension tabletop 37 to support the lower tabletop 4 33.

[0056] The extended tabletop 37 is divided into extended tabletop one 39 and extended tabletop two 40. Multiple L-shaped locking blocks 41 are fixedly installed on the bottom periphery of extended tabletop two 40. Extended tabletop one 39 has L-shaped limiting grooves 42 that match the L-shaped locking blocks 41. Multiple compression springs 43 are fixedly abutted against the side of extended tabletop two 40 opposite to extended tabletop one 39. Specifically, in this utility model, through the design of the extension mechanism, the operating table is further extended without changing its actual floor area. The usable actual space allows the operating table to meet the drawing requirements of A1 or A0 drawings, further improving the practicality of the device. Through the design of the magnetic support strip 38, while ensuring that the extension table 37 supports the lower table 33, the magnetic force of the magnetic support strip 38 restricts the position of the extension table 37 when it retracts within the upper table 3. This prevents the extension table 37 from accidentally rotating out of the upper table 3 during the adjustment process, effectively improving the stability of this type of rotatable operating table during adjustment.

[0057] Reference Figure 13-16The desktop support assembly includes multiple mounting blocks 44 fixedly disposed inside the extended tabletop 39. A drive shaft 45 is rotatably connected to the multiple mounting blocks 44. A support leg 46 for supporting the extended tabletop 37 is fixedly connected to a section of the drive shaft 45 located between the multiple mounting blocks 44. An anti-slip rubber pad 47 is fixedly disposed at the bottom of the support leg 46.

[0058] One end of the second drive shaft 45 passes through the first extension table 39 and is connected to an adjustment knob 48. The other end of the second drive shaft 45 is fixedly connected to a rotating connector 49. The rotating connector 49 is rotatably connected inside the first mounting block 44. A second rotating connector 50 is rotatably connected to the end of the first rotating connector 49. The second rotating connector 50 is fixedly disposed inside the first mounting block 44. A toothed connector 51 is movably disposed inside the first rotating connector 49 and the second rotating connector 50. The interiors of the first rotating connector 49 and the second rotating connector 50 are open. The device is provided with a first slot 52 and a second slot 53 that match the toothed connector 51. A plurality of locking blocks 54 that engage with the toothed connector 51 are fixedly provided on the side of the second slot 53 near the first slot 52. A second compression spring 55 is provided on the inner side of the second slot 53. The two ends of the second compression spring 55 are fixedly connected to the inner walls of the toothed connector 51 and the second slot 53, respectively. A pressing block 56 is movably engaged on the side of the rotating connector 49 away from the toothed connector 51. The side of the pressing block 56 away from the toothed connector 51 is fixedly connected to the second transmission shaft 45.

[0059] A connecting shaft 57 is fixedly connected to the top of the support leg 46, and a support block 58 is fixedly connected to one end of the connecting shaft 57. Multiple mounting blocks 59 are fixedly installed on the extension table 39 to facilitate the installation of the support block 58. The support block 58 is rotatably connected to the mounting block 59 via a rotating shaft. Both the top of the support block 58 and the support leg 46 have grooves 60 to facilitate their rotation inside the extension table 39. The extension table 39 has openings 61 to facilitate the rotation of the support leg 46 and the support block 58. Specifically, in this invention, the design of the anti-slip rubber pad 47 effectively increases the friction between the support leg 46 and the ground. Simultaneously, utilizing the deformation capability of the anti-slip rubber pad 47, the bottom of the support leg 46 is protected against slippage. When the sliding rubber pad 47 contacts the ground, it can retract to a certain extent under the pressure of the support leg 46 and the ground, so that the support leg 46 can normally support the extension table 37 on the ground. Through the design of the support leg 46, connecting shaft 57, support block 58 and mounting block 2 59, the support leg 46 can drive the support block 58 to rotate on the mounting block 2 59 through the connecting shaft 57 when rotating, so that the support leg 46 and support block 58 remain perpendicular to the extension table 2 40 and support the extension table 2 40. Through the design of the groove 60 and the opening 61, the normal rotation of the support leg 46 and support block 58 in the extension table 1 39 can be guaranteed, effectively eliminating the motion interference of the support leg 46 and support block 58 when rotating, and ensuring the normal use of the tabletop support component.

[0060] It should be noted that in this utility model, the second drive shaft 45 is slidably disposed inside the multiple mounting blocks 44 and the extension table 39. At the same time, the second drive shaft 45 can rotate within the mounting blocks 44 and the extension table 39. Furthermore, the fixed connection between the second drive shaft 45 and the pressing block 56 can restrict the sliding position of the second drive shaft 45 within the mounting blocks 44, thereby preventing the second drive shaft 45 from detaching from the mounting blocks 44 and ensuring the normal operation of the desktop support assembly.

[0061] In actual operation, the operator only needs to rotate the upper table 3 until it forms an L-shape with the lower table 2, then rotate the extension table 37 out of the upper table 3, so that the extension table 37 abuts against the side wall of the upper table 3. At this time, the extension table 37 and the upper table 3 remain perpendicular. Then, the extension table 40, which is locked on the extension table 39, will pop outward under the action of the compression spring 43 and stop when the L-shaped locking block 41 abuts against the top wall of the L-shaped limiting groove 42. At this time, the top bearing surface of the extension table 40 is flush with the top bearing surface of the upper table 3. Then, press the adjustment knob 48 inward to fix one end of the adjustment knob 48. The fixed drive shaft 45 drives the support leg 46 to move within the gap between the two mounting blocks 44. During this process, the drive shaft 45 presses against the pressing block 56 fixedly connected to its end, causing the pressing block 56 to press against the toothed connector 51 and drive the toothed connector 51 to gradually move into the interior of the rotating connector 50. When the toothed connector 51 is completely disengaged from the locking block 54, the fixed connection between the rotating connector 49 and the rotating connector 50 is changed to a rotating connection. Then, the operator rotates the support leg 46 inside the extension table 39 until the support leg 46 is perpendicular to the ground, and then releases it for rotation. When knob 48 is pressed, the toothed connector 51 resets under the action of compression spring 55. Since the support leg 46 is in contact with the ground through the anti-slip rubber pad 47, the operator can manually pull the support leg 46 outward a certain distance to cooperate with the compression spring 55 to make the toothed connector 51 re-engage with the locking block 54, thus fixing the angle of the support leg 46 after rotation. Then, turn the adjustment knob 31 to make the transmission shaft 30 drive the drive bevel gear 29 to rotate, thereby driving the driven bevel gear 27 meshing with it to rotate. At this time, the driven bevel gear 27 drives the drive gear 2 through the rotating sleeve 26. 4. Rotate the drive gear 24 and drive multiple drive gears 24 to rotate synchronously through the toothed belt 25 sleeved on the outside of the drive gear 24. This causes the threaded rod connected in the middle of the drive gear 24 to lift the lower table plate 32 and the lower table plate 43 upward. When the bearing surface of the lower table plate 32 and the upper table plate 3 are at the same level, stop rotating the adjustment knob 1 31 and pull out the lower table plate 43 so that it is flush with the lower table plate 32 after passing through the L-shaped guide slider 35 and the U-shaped guide groove 36. At this time, the lower table plate 433 is placed on the magnetic support strip 38. Then, lay the A0 or A1 drawing flat on the main body 1 of the rotary operating table.

[0062] The rotatable operating table provided by this utility model is used as follows:

[0063] In actual operation, the operator only needs to rotate the upper table 3 until it forms an L-shape with the lower table 2, then rotate the extension table 37 out of the upper table 3, so that the extension table 37 abuts against the side wall of the upper table 3. At this time, the extension table 37 and the upper table 3 remain perpendicular. Then, the extension table 40, which is locked on the extension table 39, will pop outward under the action of the compression spring 43 and stop when the L-shaped locking block 41 abuts against the top wall of the L-shaped limiting groove 42. At this time, the top bearing surface of the extension table 40 is flush with the top bearing surface of the upper table 3. Then, press the adjustment knob 48 inward to fix one end of the adjustment knob 48. The fixed drive shaft 45 drives the support leg 46 to move within the gap between the two mounting blocks 44. During this process, the drive shaft 45 presses against the pressing block 56 fixedly connected to its end, causing the pressing block 56 to press against the toothed connector 51 and drive the toothed connector 51 to gradually move into the interior of the rotating connector 50. When the toothed connector 51 is completely disengaged from the locking block 54, the fixed connection between the rotating connector 49 and the rotating connector 50 is changed to a rotating connection. Then, the operator rotates the support leg 46 inside the extension table 39 until the support leg 46 is perpendicular to the ground, and then releases it for rotation. When knob 48 is pressed, the toothed connector 51 resets under the action of compression spring 55. Since the support leg 46 is in contact with the ground through the anti-slip rubber pad 47, the operator can manually pull the support leg 46 outward a certain distance to cooperate with the compression spring 55 to make the toothed connector 51 re-engage with the locking block 54, thus fixing the angle of the support leg 46 after rotation. Then, turn the adjustment knob 31 to make the transmission shaft 30 drive the drive bevel gear 29 to rotate, thereby driving the driven bevel gear 27 meshing with it to rotate. At this time, the driven bevel gear 27 drives the drive gear 2 through the rotating sleeve 26. 4. Rotate the drive gear 24 and drive multiple drive gears 24 to rotate synchronously through the toothed belt 25 sleeved on the outside of the drive gear 24. This causes the threaded rod connected in the middle of the drive gear 24 to lift the lower table plate 32 and the lower table plate 43 upward. When the bearing surface of the lower table plate 32 and the upper table plate 3 are at the same level, stop rotating the adjustment knob 1 31 and pull out the lower table plate 43 so that it is flush with the lower table plate 32 after passing through the L-shaped guide slider 35 and the U-shaped guide groove 36. At this time, the lower table plate 433 is placed on the magnetic support strip 38. Then, lay the A0 or A1 drawing flat on the main body 1 of the rotary operating table.
