Description

Technical Field

[0001] The present application relates to the technical field of tables, and in particular to a health care table with a stretching structure. Background Art

[0002] At present, in daily home life, the table is one of the commonly used furniture, which is closely related to our lives. With the continuous improvement of living standards and the continuous increase of the elderly population, the requirements for various aging-friendly furniture are also increasing.

[0003] In the related art, an expandable table is generally formed by combining a foldable tabletop and a table frame. The expandable table helps to improve the practicality of the table and facilitates the use of the table in various situations.

[0004] With regard to the above-mentioned related technologies, the folding tabletop requires the operator to have certain motor abilities, which is difficult for some elderly people with limited mobility to operate. Summary of the invention

[0005] In order to ensure the practicality of the table while facilitating operation, the present application provides a health care table with a stretching structure.

[0006] The present application provides a health care table with a stretchable structure, which adopts the following technical solution:

[0007] A health care table with a stretching structure comprises a table frame, a table top is arranged on the table frame, an extension plate is arranged between the table top and the table frame, the table top and the extension plate are both arranged horizontally, the extension plate slides with the table top and the table frame respectively along its own width direction, the table frame is provided with a first driving component for the extension plate to slide along its own width direction, two extension plates are symmetrically arranged, and a stretching component is arranged between the two extension plates to make the two extension plates approach each other or move away from each other.

[0008] By adopting the above technical solution, when the desktop needs to be expanded, the operator can drive the expansion board on one side to move away from the expansion board on the other side through the driving component, and the stretching component drives the other expansion board to slide away from the expansion board synchronously. In this way, it helps to ensure practicality while facilitating the operator to expand the desktop.

[0009] Preferably, the stretching assembly includes a rotating plate, a limiting shaft and a sliding block, the limiting shaft is vertically arranged, the limiting shaft and the table frame are relatively fixed in the horizontal direction, the rotating plate is horizontally arranged, two rotating plates are arranged in the vertical direction, the limiting shaft is located in the middle of the two rotating plates, the two rotating plates are respectively rotatably connected around the limiting shaft, a sliding block is arranged at one end in the length direction of any rotating plate, any sliding block is rotatably connected to the corresponding rotating plate, a sliding groove is arranged on the side close to each other on any expansion plate, and any sliding block slides and cooperates in the corresponding side sliding groove along the length direction of the expansion plate.

[0010] By adopting the above technical solution, when the operator operates the driving assembly to make one side expansion plate slide in the direction away from the other side expansion plate, the two rotating plates rotate around the limit axis respectively, and the same end of the two rotating plates close to the expansion plate rotates in the direction of approaching each other, and the two sliding blocks close to one side of the expansion plate slide in the direction of approaching each other, and the same end of the two rotating plates away from the expansion plate rotates in the direction of approaching each other, thereby pushing the other expansion plate to move in the direction away from the expansion plate. The sliding blocks and the sliding grooves make the two ends of the two rotating plates relatively fixed with the two expansion plates within a certain degree of freedom. The synchronous movement of the two expansion plates is achieved through this mechanical structure, so that the operator only needs to operate the expansion plate on one side to drive the expansion plates on both sides to move, which is convenient for the operator to unfold the expansion plates.

[0011] Preferably, a limiting groove is provided on the upper side of the table frame, the limiting shaft and the limiting groove are slidably matched in the vertical direction, and the table top is fixedly connected to the limiting shaft.

[0012] By adopting the above technical solution, since the limiting axis is fixed to the table top, when the extension plates on both sides are moved out from the bottom of the table top, the table top falls in the vertical direction, thereby forming a complete table top between the table top and the upper side of the extension plate. In this way, the health care table is more beautiful and easier to use.

[0013] Preferably, the table top is respectively provided with a first abutting surface at both ends along the width direction of the expansion plate, and the two first abutting surfaces are arranged downwardly at an inclination from a direction away from each other to a direction approaching each other, and two second abutting surfaces are correspondingly arranged on the two expansion plates, and the two second abutting surfaces are arranged upwardly at an inclination from a direction approaching each other to a direction away from each other, and when the first driving component drives the two expansion plates to move in a direction away from each other until they are about to move out from the lower side of the table top, any of the first abutting surfaces abuts against the corresponding second abutting surface, and any of the first abutting surfaces slides together with the second abutting surface.

[0014] By adopting the above technical solution, during operation, when the two expansion boards are about to move out from the lower side of the table top, the first abutting surface abuts against the second abutting surface, and the first abutting surface and the second abutting surface slide and cooperate until the upper side of the table top and the side surfaces of the expansion boards on both sides are on the same horizontal plane. When the operator drives the expansion boards on both sides to slide in a direction close to each other, the first abutting surface and the second sliding surface slide and cooperate, so that the table top gradually rises until the lower side of the table top and the side surface of the expansion board slide in a horizontal direction. In this way, the table top is automatically lifted while the expansion boards are folded, so that it is convenient for the operator to operate the health care table.

[0015] Preferably, the first driving assembly includes a rack, a pinion and an expansion handwheel, the rack is horizontally arranged, the length direction of the rack is parallel to the width direction of the expansion plate, the rack is fixedly connected to the expansion plate on either side, the pinion is vertically arranged, the pinion is coaxially arranged with the expansion handwheel, and the rack is meshed with the pinion.

[0016] By adopting the above technical solution, the operator rotates the extension hand wheel to drive the pinion to rotate, and the pinion meshes with the rack to move the rack horizontally, and the extension plate on one side moves horizontally with the rack. In this way, it is convenient for the operator to operate the extension plate to move within the smallest possible range of movement, which helps to improve the operability of the health care table.

[0017] Preferably, a support frame is further provided on the lower side of the table frame, and a lifting component for driving the table frame to rise and fall in a vertical direction is provided between the support frame and the table frame.

[0018] By adopting the above technical solution, the height of the table top can be adjusted by adjusting the gap between the table frame and the support frame, which helps to improve the practicality of the health care table.

[0019] Preferably, the lifting assembly includes a transmission sleeve fixed to the lower side of the table frame, a transmission shaft is provided on the support frame, the transmission shaft is rotatably arranged on the support frame around its own axis direction, the transmission shaft and the transmission sleeve are provided with mutually matching threads, and a second driving assembly for driving the transmission shaft to rotate is provided on the transmission shaft.

[0020] By adopting the above technical solution, the operator operates the second driving assembly to drive the transmission shaft to rotate, and the transmission shaft causes the transmission sleeve to slide in the vertical direction through the thread, thereby driving the table frame to rise and fall in the vertical direction.

[0021] Preferably, the second driving assembly includes a lifting hand wheel, a large bevel gear and a small bevel gear, the large bevel gear is coaxially fixed to the transmission shaft, the small bevel gear is coaxially fixed to the lifting hand wheel, and the large bevel gear is meshed with the small bevel gear.

[0022] By adopting the above technical solution, the operator turns the lifting hand wheel to drive the small bevel gear to rotate around its own axis, and the small bevel gear and the large bevel gear are kneaded, so that the large bevel gear rotates around its own axis, thereby driving the transmission shaft to rotate around its own axis. In this way, the operator can turn the lifting hand wheel to make the table frame drive the table board to slide in the vertical direction, which helps to ensure the practicality of the desktop while improving the ease of operation of the health care table.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a health care table with a stretching structure.

[0033] See also Figure 1-4 The health care table with a stretching structure includes a table frame 5, on which an expansion board 2 is arranged horizontally. Two expansion boards 2 are symmetrically arranged on the table frame 5 along its own width direction, and the two expansion boards 2 are arranged at intervals. A table board 1 is also arranged on the upper side of the expansion board 2, which is arranged horizontally. A limiting axis 12 is fixed on the lower side of the table board 1. The limiting axis 12 is located at the center of the table board 1. The limiting axis 12 is located between the gaps between the two expansion boards 2, and the limiting axis 12 is arranged vertically. A limiting groove 51 is correspondingly provided on the table frame 5, and the limiting axis 12 is inserted into the limiting groove 51. The table board 1 is driven by gravity to slide and cooperate in the limiting groove 51 in the vertical direction. A first driving component 8 is arranged on one side of the expansion board 2, and the first driving component 8 drives the expansion board 2 on the table frame 5 along its own width direction. A stretching component 4 is arranged between the two expansion boards 2, and the stretching component 4 causes the two expansion boards 2 to move synchronously in a direction away from or close to each other. During actual use, the operator can drive the expansion plate 2 on one side to move away from the expansion plate 2 on the other side along its own width direction through the first driving component 8, and the expansion plate 2 drives the expansion plate 2 on the other side to move away from each other through the stretching component 4.

[0034] The table board 1 is formed with first abutting surfaces 11 on both sides along the width direction of the expansion board 2, and the two first abutting surfaces 11 are arranged downwardly in a direction away from each other and in a direction close to each other. A second abutting surface 21 is also formed on any expansion board 2. The two second abutting surfaces 21 are arranged upwardly in a direction away from each other and in a direction close to each other. A baffle 22 is also formed on one side of the two expansion boards 2 that are close to each other, and the baffle 22 is arranged horizontally. When the table board 1 slides downward under the action of gravity, the lower side of the table board 1 will abut against the upper side of the baffle 22. In actual use, when the expansion board 2 is located at the lower side of the table board 1, the upper side of the expansion board 2 abuts against the lower side of the table board 1. When the expansion board 2 is about to move out from directly below the table board 1, the table board 1 slides downward in the vertical direction under the action of gravity, and the two first abutting surfaces 11 abut against the two second abutting surfaces 21 respectively, and any first abutting surface 11 slides and cooperates with the second abutting surface 21 until the lower side of the table board 1 abuts against the upper side of the baffle 22. In this way, the upper side of the table top 1 and the upper side of the two table tops 1 are located on the same horizontal plane, thereby forming a complete table top. In this way, the expanded table top has a larger usable area, which helps to improve the practicality and aesthetics of the health care table.

[0035] When the expansion board 2 needs to be folded, the operator drives the expansion board 2 on one side to move closer to the expansion board 2 on the other side through the first driving component 8, and the stretching component 4 drives the two expansion boards 2 to move synchronously in the direction of approaching each other, and the first abutting surface 11 and the second abutting surface 21 slide and cooperate, so that the table top 1 is lifted in the vertical direction. The first abutting surface 11 and the second abutting surface 21 are tilted and arranged correspondingly, so that the table top 1 can be automatically lifted when the operator folds the expansion board 2, thereby helping to improve the operability of the health care table.

[0036] The stretching assembly 4 includes a rotating plate 43, a sliding block 41 and a rotating shaft 42. The rotating plate 43 is horizontally arranged and is located between the gaps between the two extension plates 2 that are close to each other. Two rotating plates 43 are arranged in the vertical direction. The limiting shaft 12 passes through the two rotating plates 43 along its own axial direction. Both rotating plates 43 rotate around the axial direction of the limiting shaft 12. The length directions of the two rotating plates 43 form a certain angle. One sliding block 41 is arranged at one end of the length direction of any rotating plate 43. There are four sliding blocks 41 in total, and four rotating shafts 42 are arranged corresponding to the sliding blocks 41. Any rotating shaft 42 is arranged vertically, and any rotating shaft 42 passes through the corresponding sliding block 41 and the rotating plate 43 along its own axial direction. One end of any sliding block 41 and the corresponding rotating plate 43 rotates around the axial direction of the rotating shaft 42.

[0037] A sliding groove 221 is also provided on the side where the two baffles 22 are close to each other, and the length direction of the sliding groove 221 is parallel to the length direction of the expansion plate 2. The side where the two sliding grooves 221 are close to each other is open, and the two ends of the two rotating plates 43 are respectively inserted into the two sliding grooves 221. The two sliding blocks 41 on one side of the two rotating plates 43 along the width direction of the expansion plate 2 are both located in the sliding groove 221 on the corresponding side. Any sliding block 41 slides and cooperates with the sliding groove 221 along the length direction of the sliding groove 221. In actual operation, when the first driving component 8 drives the expansion plate 2 on one side to move away from the expansion plate 2 on the other side, the same end of the two rotating plates 43 close to the expansion plate 2 rotates in a direction close to each other, the two sliding blocks 41 close to the expansion plate 2 on one side slide in a direction close to each other, and the same end of the two rotating plates 43 away from the expansion plate 2 rotates in a direction close to each other, thereby pushing the expansion plate 2 on the other side to move away from the expansion plate 2.

[0038] The first drive assembly 8 includes a rack 81, a pinion 82 and an expansion hand wheel 83. The rack 81 is horizontally arranged, the tooth portion of the rack 81 is arranged on the lower side of the rack 81, the rack 81 is fixed on the lower side of the expansion board 2 on one side, and the length direction of the rack 81 is parallel to the width direction of the expansion board 2. The pinion 82 is vertically arranged, and the thickness direction of the pinion 82 is parallel to the length direction of the expansion board 2. The pinion 82 is rotated around its own axis and arranged on the table frame 5, and the expansion hand wheel 83 is coaxially fixed with the pinion 82. The expansion hand wheel 83 is located outside the table frame 5. The pinion 82 is meshed with the rack 81. In the actual operation process, the operator rotates the expansion hand wheel 83, and the expansion hand wheel 83 drives the pinion 82 to rotate synchronously, and the rack 81 is meshed with the pinion 82, so that the expansion board 2 slides along its own width direction. This operation mode allows the operator to operate the expansion board 2 to unfold and retract in the smallest possible range of activity. While ensuring the ease of operation of the first drive assembly 8, it is simple and reliable, difficult to make mistakes, and friendly to the elderly.

[0039] The table board 1 is also provided with baffles 3 on both sides along the length direction of the expansion board 2, baffles 3 are also provided on both sides in the width direction of the expansion board 2, and baffles 3 are also provided on the side where the two expansion boards 2 are away from each other. The baffles 3 help to reduce the possibility of objects falling on the desktop, which is also a modification suitable for the elderly.

[0040] A support frame 7 is also provided at the lower side of the table frame 5. A lifting assembly 6 is provided between the support frame 7 and the table frame 5. The lifting assembly 6 includes a transmission sleeve 61 and a transmission shaft 62. The transmission sleeve 61 and the transmission shaft 62 are both vertically arranged. The transmission sleeve 61 is coaxially sleeved on the outer side of the transmission shaft 62. The top of the transmission sleeve 61 is fixedly connected to the lower side of the table frame 5. The inner side of the transmission sleeve 61 and the outer side of the transmission shaft 62 are respectively provided with mutually matching threads. A bearing 71 is sleeved at the lower end of the transmission shaft 62, and the bearing 71 is embedded in the support frame 7. The transmission shaft 62 is rotatably connected to the support frame 7 through the bearing 71. A second driving assembly 9 for rotating the transmission shaft 62 around its own axis direction is also provided in the support frame 7. In actual operation, the second driving assembly 9 drives the transmission shaft 62 to rotate, and the transmission shaft 62 causes the transmission sleeve 61 to slide in the vertical direction through the thread, and the transmission sleeve 61 drives the table frame 5 to slide in the vertical direction. The operator can control the rotation of the transmission shaft 62 through the second driving assembly 9 according to actual needs, thereby changing the height of the desktop. This method helps to improve the practicality of the health care table.

[0041] The second drive assembly 9 also includes a large bevel gear 91, a small bevel gear 92 and a lifting handwheel 93. The large bevel gear 91 is horizontally arranged, and the large bevel gear 91 is sleeved on the transmission shaft 62, and the large bevel gear 91 is coaxially fixed with the transmission shaft 62. The small bevel gear 92 is vertically arranged, and the small bevel gear 92 is coaxially fixed with the lifting handwheel 93. The lifting handwheel 93 is located outside the support frame 7. The small bevel gear 92 is meshed with the large bevel gear 91. In the actual operation process, the operator rotates the lifting handwheel 93, and the lifting handwheel 93 drives the small bevel gear 92 to rotate along its own axis direction, and the small bevel gear 92 is meshed with the large bevel gear 91, driving the large bevel gear 91 to rotate, and the large bevel gear 91 drives the transmission shaft 62 to rotate. In this way, the operator can operate the height of the desktop within a minimum range of activity, and at the same time, it is simple and reliable while ensuring the ease of operation of the second drive assembly 9.

[0042] A housing 52 is also sleeved on the outside of the transmission sleeve 61. The housing 52 is covered on the outside of the support frame 7. The housing 52 and the support frame 7 slide together in the vertical direction. The upper side of the housing 52 is fixedly connected to the lower side of the table frame 5. The housing 52 helps to separate the lifting assembly 6 and the second drive assembly 9 from the outside, which helps to ensure the safety of the health care chair.

[0043] The implementation principle of a health care table with a stretching structure in the embodiment of the present application is as follows: when the desktop needs to be extended, the operator can rotate the extension hand wheel 83, and the extension hand wheel 83 drives the pinion 82 to rotate, and the pinion 82 and the rack 81 are meshed, thereby driving the extension plate 2 fixed on the rack 81 to move to the side away from the other side extension plate 2, and the distance between the extension plate 2 and the limit shaft 12 increases, thereby driving the same end of the two rotating plates 43 close to the extension plate 2 to rotate in a direction close to each other, and the same end of the two rotating plates 43 away from the side of the extension plate 2 also rotates in a direction close to each other, thereby pushing the other side extension plate 2 to move away from the extension plate 2, so that the two extension plates 2 move synchronously. When the two side extension plates 2 are moved out from the lower side of the table board 1, the table board 1 slides in the vertical direction under the action of gravity, and the lower side of the table board 1 abuts against the upper side of the baffle 22, so that a complete desktop is formed between the upper side of the table board 1 and the upper sides of the two extension plates 2.

[0044] When the height of the desktop needs to be changed, the operator rotates the lifting hand wheel 93, which drives the small bevel gear 92 to rotate, thereby driving the large bevel gear 91 to rotate, and the large bevel gear 91 drives the transmission shaft 62 to rotate, and the transmission shaft 62 drives the transmission sleeve 61 to slide in the vertical direction, thereby driving the table frame 5, and the table frame 5 drives the desktop to slide in the vertical direction. In this way, the operator only needs to operate the expansion hand wheel 83 and the lifting hand wheel 93 to achieve the expansion of the desktop and the change of the desktop height, which helps to ensure the practicality of the health care table while improving the ease of operation.

[0045] 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.
