Description

Technical Field

[0001] The present application relates to the field of lifting tables, and in particular to an angle-adjustable lifting table. Background Art

[0002] In order to reduce various lumbar and spinal diseases caused by long-term sitting in the office, it is necessary to use lifting tables to provide office workers with two working modes: sitting and standing.

[0003] In the related art, the lifting table mainly includes a base, a lifting frame and a table top. The lifting frame is slidably connected to the base in the vertical direction, and an adjustment seat is rotatably connected to the lifting frame, and the adjustment seat is fixed to the table top. There is a friction-increasing pad between the adjustment seat and the lifting frame. The friction-increasing pad is made of rubber, and a plurality of friction-increasing protrusions are arranged on the surface of the friction-increasing pad. When the angle of the table top needs to be adjusted, the user directly rotates the table top. At this time, under the action of the friction-increasing pad and the friction-increasing protrusion, the friction between the adjustment seat and the lifting frame is increased, that is, the friction-increasing pad and the friction-increasing protrusion cooperate to play a damping role, so that the table top whose angle is adjusted is not easy to reset under its own weight.

[0004] During actual use, after long-term use, the friction-increasing pads and friction-increasing protrusions of the table top will wear out, that is, the damping capacity of the friction-increasing pads and friction-increasing protrusions between the adjustment seat and the lifting frame will decrease. At this time, the table top is easy to reset under its own gravity, which affects the use of the table top, so it needs to be improved. Utility Model Content

[0005] In order to improve the above problems, the present application provides an angle-adjustable lifting table.

[0006] The present application provides an angle-adjustable lifting table, which adopts the following technical solution:

[0007] An angle-adjustable lifting table comprises a support, a bracket and a table top, wherein the bracket is arranged on the support in a vertical direction, a lifting frame is slidably connected in the bracket, a connecting seat is arranged on the lifting frame, an adjustment seat is arranged on the table top, the adjustment seat is rotatably connected to the connecting seat, a first adjusting disk is arranged on the adjustment seat, a second adjusting disk is arranged on the connecting seat, the first adjusting disk and the second adjusting disk cooperate to form a locking cavity, the first adjusting disk is rotatably connected to the second adjusting disk, and a locking assembly for limiting the rotation of the first adjusting disk is arranged in the locking cavity;

[0008] The locking assembly includes a control disk and a plurality of locking plates. The control disk is rotatably connected in the locking cavity. The plurality of locking plates are slidably connected in the locking cavity. A gear ring is provided on the inner wall of the second adjusting disk. Each of the locking plates is provided with a tooth surface matching the gear ring. The control disk is used to control the tooth surfaces on each locking plate to mesh with the gear ring.

[0009] By adopting the above technical solution, when the height of the lifting table needs to be adjusted, the operator controls the lifting frame to move, and the lifting frame controls the connection seat to move, and the connection seat drives the adjustment seat and the table top to move in turn to adjust the vertical height of the table top. When the angle of the table top needs to be adjusted, the operator turns the control disk, and the control disk controls each locking plate to move in a direction away from the gear ring, so that the tooth surface on the locking plate is separated from the gear ring to contact the lock of the first adjustment disk. At this time, the operator can rotate the table top, and when the table top rotates, the adjustment seat and the first adjustment disk rotate accordingly, which reduces the possibility of wear between the adjustment seat and the connection seat, and reduces the possibility of the table top resetting under its own gravity after long-term use, thereby improving the stability of the lifting table when in use.

[0010] Preferably, the control disk is provided with a plurality of connecting plates, each of which is provided with a control plate on the side facing away from the control disk, each of which corresponds to a locking plate, each of which is provided with a connecting hole matching the connecting plate, and the inner wall of the connecting hole is provided with a control hole matching the control plate, when the control plate abuts against the inner wall of the connecting hole at the corresponding position, the tooth surface on the locking plate meshes with the gear ring, and when the control plate abuts against the inner wall of the control hole at the corresponding position, the tooth surface on the locking plate is separated from the gear ring.

[0011] By adopting the above technical solution, when the first adjustment disk is unlocked, the control disk drives each connection plate and the control plate to rotate, and when the control plate rotates to abut against the inner wall of the control hole, the control plate provides a pulling force to the locking plate, so that the locking plate moves in a direction away from the gear ring. When the side of the control plate away from the control disk is completely in contact with the inner wall of the control hole, and at the same time, the side of the connection plate away from the control disk is completely in contact with the inner wall of the connection hole, the tooth surface on the locking plate is completely separated from the gear ring, and the operator can adjust the angle of the table top.

[0012] Preferably, a plurality of guide grooves are formed on the inner wall of the first adjusting disk, each of the locking plates corresponds to a guide groove, and the locking plates are slidably connected to the guide grooves at corresponding positions.

[0013] By adopting the above-mentioned technical solution, when the control plate contacts the inner wall of the control hole at the corresponding position, the control plate can control the locking plate at the corresponding position to move along the guide groove at the corresponding position. At this time, the guide groove provides guidance for the locking plate at the corresponding position, thereby improving the stability of the locking plate during movement, thereby improving the stability of the operator when adjusting the angle of the table top.

[0014] Preferably, the control disk is controlled by a control shaft, and the control disk is coaxially arranged on the control shaft. A spring is wound around the control shaft. A connecting groove is opened in the first adjustment disk, and one end of the spring away from the control shaft is inserted into the connecting groove, and the spring is always in a compressed state.

[0015] By adopting the above technical solution, when the operator does not adjust the angle of the table board, under the action of the spring rebound force, the control shaft applies pressure, and the control shaft then applies pressure to the control disk, so that the control plate is not easy to rotate. At this time, the control plate controls the tooth surface of each locking plate to mesh with the gear ring to lock the first adjustment disk. When the angle of the table board is adjusted, the operator rotates the control shaft, the control shaft rotates and compresses the spring, and the control shaft drives the control disk to rotate. Each control plate on the control disk can control the movement of the locking plate at the corresponding position to unlock the first adjustment disk. After the angle adjustment of the table board is completed, the operator releases the control shaft, and under the action of the spring rebound force, the control shaft and the control disk automatically reset. At this time, each control plate on the control disk can drive the locking plate at the corresponding position to move toward the gear ring, so that the tooth surface of the locking plate meshes with the gear ring again to continue to lock the first adjustment disk, thereby providing convenience for the operator to adjust the angle of the table board.

[0016] Preferably, one end of the control shaft away from the control disk is coaxially connected with a control handle.

[0017] By adopting the above technical solution, the control handle functions as a lever arm of the control shaft, thereby providing convenience for the operator to rotate the control shaft.

[0018] Preferably, a fixing groove is formed on the control handle, the control shaft extends into the control groove, and the control handle is connected to the control shaft by bolts.

[0019] By adopting the above technical solution, when the control panel needs to be installed, the operator aligns the control shaft with the control groove, and then moves the control handle in the direction of the control shaft so that the control shaft is inserted into the control groove, and then uses bolts to fix the control shaft and the control handle to complete the installation between the control shaft and the control handle, thereby providing convenience for the installation of the control shaft and the control handle.

[0020] Preferably, a connecting block is provided on the first adjusting disk, a clearance hole is provided on the adjusting seat, and the connecting block is arranged in the clearance hole.

[0021] By adopting the above technical solution, when installing the first adjusting disk onto the adjusting seat, the operator aligns the connecting block with the connecting hole, and then inserts the connecting block into the connecting hole. At this time, the connecting block cooperates with the connecting hole to determine the position of the first adjusting disk and the adjusting seat, thereby providing convenience for the operator to connect the first adjusting disk and the adjusting seat.

[0022] Preferably, a gas spring is provided in the bracket, an output end of the gas spring is connected to the lifting frame, and an adjusting handle for controlling the valve switch of the gas spring is rotatably connected to the table top.

[0023] By adopting the above technical solution, when the height of the table top needs to be adjusted, the operator turns the adjustment handle, and the control handle controls the valve of the gas spring. When the valve of the gas spring is in the open state, if no downward pressure is applied to the table top, the output end of the gas spring can drive the lifting frame to move away from the ground to raise the table top. If downward pressure is applied to the table top, pressure is applied to the output end of the gas spring, and at this time the output end of the gas spring can drive the lifting frame to move toward the ground to lower the table top. After the height adjustment of the table top is completed, release the control handle so that the valve of the gas spring is in the closed state again, and at this time the height of the table top can be limited.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By setting a control disc, a locking plate with a toothed surface and a gear ring matched with the toothed surface, when the toothed surface of the locking plate is meshed with the gear ring, the first adjustment disc is in a locked state to adjust the angle of the table board. After the toothed surface of the locking plate is separated from the gear ring, the second adjustment disc is in an unlocked state, and the angle of the table board can be adjusted, which reduces the possibility of the table board resetting under its own weight after the adjustment seat and the connecting seat are worn, thereby improving the stability of the lifting table when in use;

[0026] 2. By setting the guide groove, the guide groove provides guidance for the locking plate at the corresponding position, thereby improving the stability of the locking plate when moving, so that the locking plate can more stably control the unlocking and locking of the first adjusting disk;

[0027] 3. By setting the control handle, the control handle is convenient for rotating the control shaft, and the control shaft drives the control disk to rotate, and the control disk can control the movement of each locking plate, thereby providing convenience for the operator to adjust the angle of the table board.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses an angle-adjustable lifting table. Figure 1 and Figure 2 An angle-adjustable lifting table includes a support 1, a bracket 2 and a table top 3. The bracket 2 is fixed on the support 1 in the vertical direction. A lifting frame 21 is slidably connected in the bracket 2, and a connecting seat 22 is fixed on the lifting frame 21. An adjustment seat 31 is fixed on the table top 3, and the adjustment seat 31 is rotatably connected to the connecting seat 22. A first adjustment disk 32 is fixed on the adjustment seat 31, and a second adjustment disk 23 is fixed on the connecting seat 22. The first adjustment disk 32 is rotatably connected to the second adjustment disk 23. A locking cavity 4 is formed between the first adjustment disk 32 and the second adjustment disk 23, and a locking component 5 for limiting the rotation of the first adjustment disk 32 is provided in the locking cavity 4.

[0035] Reference Figure 1 A gas spring 24 is fixed in the bracket 2 along the vertical direction, the output end of the gas spring 24 is fixed to the lifting frame 21, and an adjusting handle 33 for controlling the valve switch of the gas spring 24 is rotatably connected to the table top 3.

[0036] When the height of the table top 3 needs to be adjusted, the operator turns the adjustment handle 33, and the control handle 61 controls the valve of the gas spring 24. When the valve of the gas spring 24 is in the open state, if no downward pressure is applied to the table top 3, the output end of the gas spring 24 can drive the lifting frame 21 to move away from the ground to raise the table top 3. If downward pressure is applied to the table top 3, pressure is applied to the output end of the gas spring 24, and at this time, the output end of the gas spring 24 can drive the lifting frame 21 to move toward the ground to lower the table top 3. After the height adjustment of the table top 3 is completed, the control handle 61 is released, so that the valve of the gas spring 24 is in the closed state again, and at this time, the height of the table top 3 can be limited.

[0037] Reference Figure 2 and Figure 3 The locking assembly 5 includes a control disk 51 and a plurality of locking plates 52. The control disk 51 is rotatably connected in the locking chamber 4. The locking plates 52 are evenly arranged on the outside of the control disk 51. A gear ring 231 is fixed to the inner wall of the second adjusting disk 23, and a tooth surface 521 matching the gear ring 231 is formed on each locking plate 52. The control disk 51 is used to control the tooth surface 521 of each locking plate 52 to mesh with the gear ring 231.

[0038] A plurality of connecting plates 53 are fixed on the control disk 51, and a control plate 54 is fixed on the side of each connecting plate 53 away from the control disk 51, and each control plate 54 corresponds to a locking plate 52. Each locking plate 52 is provided with a connecting hole 522 matched with the connecting plate 53, and the inner wall of the connecting hole 522 is provided with a control hole 523 matched with the control plate 54. When the control plate 54 abuts against the inner wall of the connecting hole 522 at the corresponding position, the tooth surface 521 of the locking plate 52 meshes with the gear ring 231; when the control plate 54 abuts against the inner wall of the control hole 523 at the corresponding position, the tooth surface 521 of the locking plate 52 separates from the gear ring 231.

[0039] When the angle of the table top 3 needs to be adjusted, the control plate 51 rotates and drives each connecting plate 53 and the control plate 54 to rotate. When the control plate 54 contacts the inner wall of the control hole 523 at the corresponding position, the control plate 54 applies pressure to the locking plate 52, so that the locking plate 52 moves in a direction away from the gear ring 231. When the control plate 54 is completely in contact with the inner wall of the control hole 523 at the corresponding position, the connecting plate 53 is completely in contact with the inner wall of the connecting hole 522 at the corresponding position, and the tooth surface 521 on the locking plate 52 is completely separated from the gear ring 231, so that the first adjustment plate 32 is in an unlocked state. At this time, the operator can rotate the table top 3, and the rotation of the table top 3 drives the adjustment seat 31 and the first adjustment plate 32 to rotate. After the angle adjustment of the table top 3 is completed, the control plate 54 is reversed. At this time, the control plate 54 contacts the inner wall of the control hole 523 to apply pressure to the locking plate 52. When the control plate 54 moves to abut against the inner wall of the moving hole, the tooth surface 521 on the locking plate 52 re-engages with the gear ring 231 to complete the locking of the first adjustment disk 32, reducing the possibility of the table top 3 being reset under its own weight due to wear between the adjustment seat 31 and the connecting seat 22, thereby improving the stability of the lifting table during use.

[0040] Reference Figure 4In order to improve the stability of each locking plate 52 when it moves, a plurality of guide grooves 321 are provided on the inner wall of the first adjustment disk 32. Each locking plate 52 corresponds to a guide groove 321, and the locking plate 52 is slidably connected to the guide groove 321 at the corresponding position. When the control board 54 controls the locking plate 52, the guide groove 321 provides guidance for the locking plate 52 at the corresponding position, thereby improving the stability of the locking plate 52 when it moves, and at the same time improving the stability of the operator when controlling the first adjustment disk 32 to lock or unlock.

[0041] Reference Figure 3 and Figure 4 The control disk 51 is controlled by the control shaft 6, and the control shaft 6 rotates relative to the first adjustment disk 32 and the adjustment seat 31. A spring 7 is wound around the control shaft 6, and a connecting groove 322 is provided in the first adjustment disk 32. One end of the spring 7 away from the control shaft 6 is inserted into the connecting groove 322, and the spring 7 is always in a compressed state.

[0042] In order to facilitate the control of the control shaft 6, a control handle 61 is provided on the control shaft 6. A fixing groove 611 is provided on the control handle 61, and the control shaft 6 extends into the control groove, and the control handle 61 is connected to the control shaft 6 by bolts. When the control handle 61 needs to be installed, the operator moves the control handle 61 so that the control shaft 6 is inserted into the control groove to limit the control shaft 6. The operator then uses bolts to fix the control shaft 6 and the control handle 61, thereby providing convenience for the operator to connect the control handle 61 and the control shaft 6.

[0043] During the process of adjusting the angle of the table top 3, the operator rotates the control handle 61, the control handle 61 drives the control shaft 6 to rotate, the control shaft 6 drives the control disk 51 to rotate, the control disk 51 drives each connecting plate 53 and the control plate 54 to rotate, and the control plate 54 can control the locking plate 52 at the corresponding position to move in the direction away from the ring gear 231. At this time, the spring 7 is further compressed. After each locking plate 52 is separated from the ring gear 231, the operator can adjust the angle of the table top 3. After the angle adjustment of the table top 3 is completed, the operator releases the control handle 61. At this time, under the action of the rebound force of the spring 7, a reaction force is applied to the control shaft 6, so that the control shaft 6 and the control handle 61 are reset. The control shaft 6 then drives the control disk 51 to reverse. The control plate 54 on the control disk 51 applies a thrust to the locking plate 52, so that the tooth surface 521 on each locking plate 52 re-engages with the gear ring 231 to lock the first adjustment disk 32, that is, to lock the angle of the table top 3, thereby further facilitating the operator to adjust the angle of the table top 3.

[0044] Reference Figure 2A connecting block 323 is fixed on the first adjusting disk 32, a clearance hole 311 is opened on the adjusting seat 31, and the connecting block 323 is arranged in the clearance hole 311. When the control board 54 needs to be installed, the operator makes the control shaft 6 face the control groove, and then moves the control handle 61 toward the control shaft 6 so that the control shaft 6 is inserted into the control groove, and then uses bolts to fix the control shaft 6 and the control handle 61 to complete the installation between the control shaft 6 and the control handle 61, thereby providing convenience for the installation of the control shaft 6 and the control handle 61.

[0045] Reference Figure 1 and Figure 2 In order to improve the connection stability between the first adjustment disk 32 and the second adjustment disk 23, a limit cover 8 is provided on the outer side of the first adjustment disk 32 and the second adjustment disk 23, the first adjustment disk 32 is rotatably connected to the inner wall of the limit cover 8, and the second adjustment disk 23 abuts against the inner wall of the limit cover 8. The limit cover 8 provides support for the first adjustment disk 32 and the second adjustment disk 23, so that the first adjustment disk 32 and the second adjustment disk 23 are not easily separated, so that the subsequent operator can adjust the angle of the table top 3.

[0046] Reference Figure 1 The support 1 includes a support plate 11 and two support rods 12 arranged opposite to each other. The bracket 2 is fixed on the support plate 11. One end of the support plate 11 is connected to one of the support rods 12, and the other end is connected to the other support rod 12. One end of the support rod 12 is tilted away from the support plate 11 compared to the other end of the support rod 12. At this time, the tilted support rod 12 forms a first space 13 and a second space 14 of different sizes between the support plate 11 and the two support rods 12, and the first space 13 is larger than the second space 14. When multiple lifting tables need to be stored, the operator controls the table board 3 to rotate to the extreme position, and then inserts the second space 14 of the lifting table into the first space 13 of the adjacent lifting table, thereby providing convenience for the storage of the lifting table as a whole.

[0047] Reference Figure 1 Universal wheels 121 are provided at both ends of the support rod 12, thereby facilitating the movement of the entire lifting table.

[0048] The implementation principle of the angle-adjustable lifting table in the embodiment of the present application is as follows: during the use of the lifting table, the operator adjusts the position of the lifting frame 21 to change the height of the table board 3. The operator then rotates the control handle 61, which in turn drives the control shaft 6, the control plate 54, and each connecting plate 53 and the control plate 54 to rotate, so as to control each locking plate 52 to separate from the gear ring 231. At this time, the angle of the table board 3 can be adjusted, so that the adjustment seat 31 and the connecting seat 22 are not easily worn, and the possibility of the table board 3 being reset under its own weight is reduced, thereby improving the stability of the lifting table during use.

[0049] 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.
