[0040] Please refer to Figures 1 to 3 The utility model embodiment provides a lifting table 100, lifting table 100 can be placed on the ground lifting table 100, can be placed on the table lifting table 100 of other table outside lifting table 100.

[0041] Lifting table 100 includes base 110, table plate assembly 130, at least one first support mechanism 150, support 170 and second support mechanism 190.

[0042] Among them, base 110 can be placed on the ground, the tabletop of other table outside lifting table 100 or other position.

[0043] The table board assembly 130 is arranged above the base 110, and the at least one first supporting mechanism 150, the supporting device 170 and the second supporting mechanism 190 are connected between the base 110 and the table board assembly 130, and are used to support the table board assembly 130 to support the table board assembly 130 in multiple positions and reduce the shaking of the table board assembly 130.

[0044] The at least one first supporting mechanism 150 can be one first supporting mechanism 150, two first supporting mechanisms 150, three first supporting mechanisms 150 or other number of first supporting mechanisms 150. When the number of the first supporting mechanisms 150 is two or more, the structure and movement mode of each first supporting mechanism 150 are substantially the same, and for the convenience of description, one first supporting mechanism will be taken as an example for explanation and description below.

[0045] Please refer to Figures 3 to 4 , the first supporting mechanism 150 includes a first supporting rod 151, a second supporting rod 153, a third supporting rod 155 and a fourth supporting rod 157, the bottom end of the first supporting rod 151 and the bottom end of the second supporting rod 153 are rotatably connected with the base 110, the top end of the first supporting rod 151 is rotatably connected with the bottom end of the third supporting rod 155, the top end of the second supporting rod 153 is rotatably connected with the bottom end of the fourth supporting rod 157, and the top end of the third supporting rod 155 and the top end of the fourth supporting rod 157 are rotatably connected with the table board assembly 130, so that the first supporting rod 151, the second supporting rod 153, the third supporting rod 155 and the fourth supporting rod 157 cooperate to form a quadrilateral linkage supporting mechanism, and the first supporting rod 151, the second supporting rod 153, the third supporting rod 155 and the fourth supporting rod 157 can rotate with the lifting of the table board assembly 130 to be unfolded or folded when the table board assembly 130 is lifted relative to the base 110, so that the table board assembly 130 can be more flexibly supported.

[0046] Specifically, when the table board assembly 130 is lifted relative to the base 110, the first supporting rod 151 and the third supporting rod 155 rotate synchronously, the top end of the third supporting rod 155 moves away from the bottom end of the first supporting rod 151 to realize the unfolding movement of the first supporting rod 151 and the third supporting rod 155; the second supporting rod 153 and the fourth supporting rod 157 rotate synchronously, and the top end of the fourth supporting rod 157 moves away from the bottom end of the second supporting rod 153 to realize the unfolding movement of the second supporting rod 153 and the fourth supporting rod 157.

[0047] When the table board assembly 130 is lowered relative to the base 110, the first support rod 151 and the third support rod 155 rotate synchronously, the top end of the third support rod 155 is close to the bottom end of the first support rod 151 to realize the folding movement of the first support rod 151 and the third support rod 155; the second support rod 153 and the fourth support rod 157 rotate synchronously, the top end of the fourth support rod 157 is close to the bottom end of the second support rod 153 to realize the folding movement of the second support rod 153 and the fourth support rod 157.

[0048] It should be noted that the rotation axis of the bottom end of the first support rod 151 and the rotation axis of the bottom end of the second support rod 153 can be collinear or not collinear, and the rotation axis of the top end of the third support rod 155 and the rotation axis of the top end of the fourth support rod 157 can be collinear or not collinear.

[0049] The bottom end of the first support rod 151 and the bottom end of the second support rod 153 are connected by meshing transmission, the top end of the third support rod 155 and the top end of the fourth support rod 157 are connected by meshing transmission, in this way, the first support mechanism 150 can support the table board assembly 130 through the meshing force of the meshing teeth between the first support rod 151 and the second support rod 153 and the meshing force of the meshing teeth between the third support rod 155 and the fourth support rod 157, and the first support rod 151 and the second support rod 153 can rotate synchronously, and the third support rod 155 and the fourth support rod 157 can also rotate synchronously, so that the first support rod 151, the second support rod 153, the third support rod 155 and the fourth support rod 157 can rotate synchronously, which helps to reduce the situation that the table board assembly 130 is inclined due to the different movements of the support rods.

[0050] As an example, taking the first support rod 151 and the second support rod 153 as an example, the outer periphery of the bottom end of the first support rod 151 can be convexly provided with a plurality of first teeth 1511 arranged at intervals, and the bottom end of the second support rod 153 can be convexly provided with a plurality of second teeth 1531 arranged at intervals, the plurality of first teeth 1511 and the plurality of second teeth 1531 can mesh with each other to realize meshing transmission. When the first support rod 151 rotates, the first teeth 1511 make the second support rod 153 rotate in the opposite direction through the meshing with the second teeth 1531, so that the rotation of the first support rod 151 and the second support rod 153 is always opposite in the opposite direction, so as to better support the table board assembly 130.

[0051] Similarly, the outer periphery of the bottom end of the third support rod 155 can be provided with a plurality of third teeth 1551 arranged at intervals, and the bottom end of the fourth support rod 157 can be provided with a plurality of fourth teeth 1571 arranged at intervals. The plurality of third teeth 1551 and the plurality of fourth teeth 1571 can be engaged with each other to achieve meshing transmission. The specific transmission mode can refer to the transmission mode of the first teeth 1511 and the second teeth 1531 described above, and will not be described again.

[0052] Referring to Figure 3 and Figure 5 The bottom end of the support 170 is connected to the base 110, and the top end of the support 170 is connected to the table board assembly 130. The support 170 is used to drive the table board assembly 130 to move up and down relative to the base 110 through telescopic movement to adjust the distance between the table board assembly 130 and the base 110 in the vertical direction Z, and to maintain the distance between the table board assembly 130 and the base 110, so that the table board assembly 130 can be flexibly controlled relative to the base 110 by the support 170.

[0053] Specifically, the support 170 itself can be telescopic, and the support 170 can drive the table board assembly 130 to move up and down relative to the base 110 through telescopic movement, so that the distance between the table board assembly 130 and the base 110 in the vertical direction Z can be adjusted. Moreover, the support 170 can have a self-locking function to fix the table board assembly 130 relative to the base 110, so that the distance between the table board assembly 130 and the base 110 in the vertical direction Z can be maintained.

[0054] As an example, the support 170 can adopt a gas spring, an electric push rod 175, a linear motor, a lead screw module, etc. The support 170 can also adopt a telescopic rod assembly that can be telescopic but has no power source. The user can manually operate the telescopic rod assembly to extend or retract the telescopic rod.

[0055] The second supporting mechanism 190 comprises a connecting rod 191 and a moving piece 193. The moving piece 193 is movably connected to one of the base 110 or the tabletop assembly 130. One end of the connecting rod 191 is rotatably connected to the other one of the base 110 or the tabletop assembly 130. The other end of the connecting rod 191 is rotatably connected to the moving piece 193. Thus, as the tabletop assembly 130 is lifted or lowered, the connecting rod 191 can rotate relative to one of the base 110 or the tabletop assembly 130 to push the moving piece 193 to move on the other one of the base 110 or the tabletop assembly 130. The connecting rod 191 and the moving piece 193 can always abut between the tabletop assembly 130 and the base 110, which helps to more stably lift or lower the tabletop assembly 130 and improves the shaking of the tabletop assembly 130. The support 170, the first supporting mechanism 150 and the second supporting mechanism 190 can cooperate to support the tabletop assembly 130 at multiple positions, which helps to more stably support the tabletop assembly 130 at a desired position and reduces the shaking of the tabletop assembly 130. In addition, compared with the lifting table in the related art which is provided with two supports, the lifting table 100 provided by the embodiment of the present application only needs to be provided with one support 170 to drive the lifting of the tabletop assembly 130, which not only can provide more sufficient support force for the tabletop assembly 130, but also can stably lift or lower the tabletop assembly 130, reduces the number of supports 170, reduces the manufacturing cost of the lifting table 100, and is more convenient to operate.

[0056] As an example, the moving piece 193 is movably connected to the base 110. The bottom end of the connecting rod 191 is rotatably connected to the moving piece 193. The top end of the connecting rod 191 is rotatably connected to the tabletop assembly 130.

[0057] As another example, the moving piece 193 is movably connected to the tabletop assembly 130. The bottom end of the connecting rod 191 is rotatably connected to the base 110. The top end of the connecting rod 191 is rotatably connected to the moving piece 193.

[0058] For the convenience of description, the following will be explained and described by taking the moving piece 193 movably connected to the base 110, the bottom end of the connecting rod 191 rotatably connected to the moving piece 193, and the top end of the connecting rod 191 rotatably connected to the tabletop assembly 130 as an example, unless otherwise specified.

[0059] The support 170 and the connecting rod 191 are spaced apart along the first horizontal direction X. The projections of the support 170 and the connecting rod 191 in a vertical plane perpendicular to the first horizontal direction X are cross-shaped. Thus, the support 170 and the second supporting mechanism 190 can more stably support the tabletop assembly 130, and further improve the shaking of the tabletop assembly 130.

[0060] The first horizontal direction X can be substantially the front-rear direction of the lifting table 100.

[0061] The rotation axis of the bottom end of the first support rod 151, the rotation axis of the top end of the first support rod 151, the rotation axis of the bottom end of the second support rod 153, the rotation axis of the top end of the second support rod 153, the rotation axis of the bottom end of the third support rod 155, the rotation axis of the top end of the third support rod 155, the rotation axis of the bottom end of the fourth support rod 157, the rotation axis of the top end of the fourth support rod 157, and the rotation axis of the top end of the connecting rod 191 can be arranged along the first horizontal direction X.

[0062] Please refer to Figure 1 and Figure 3 In some embodiments, the table board assembly 130 includes a table board 131 and a top frame 133, and the top frame 133 can be fixedly connected to the bottom surface of the table board 131.

[0063] The connecting rod 191, the support 170, the third support rod 155, and the fourth support rod 157 in the above embodiments can be connected to the top frame 133 to be connected to the table board assembly 130.

[0064] In some embodiments, the table board assembly 130 can further include a keyboard support 135, which can be used to place a keyboard, and the keyboard support 135 is connected to the table board 131, located below the table board 131, and at least a part of the keyboard support 135 is located in front of the table board 131 to reduce the obstruction of the table board 131 to the user when using the keyboard.

[0065] In some embodiments, the connecting rod 191 can be inclined relative to the vertical direction Z, which helps the moving piece 193 to move more smoothly and helps to avoid the situation that the moving piece 193 is stuck due to the vertical arrangement of the connecting rod 191. Similarly, the support 170 can also be arranged to be inclined relative to the vertical direction Z, so as to cross the connecting rod 191 in the projection of the vertical plane perpendicular to the first horizontal direction X in the shape of X.

[0066] Specifically, in the projection of the support 170 and the connecting rod 191 in the vertical plane perpendicular to the first horizontal direction X, the support 170, the connecting rod 191, and the table board assembly 130 can jointly enclose a triangular space, and the support 170, the connecting rod 191, and the base 110 can also jointly enclose a triangular space, and the two triangular spaces can be symmetrically distributed along the vertical direction Z, so as to form two triangular structures to more stably support the table board assembly 130. Among them, the two triangular spaces in the present embodiment can be isosceles triangular spaces or other triangular spaces.

[0067] As an example, along the second horizontal direction Y, the bottom end of the support 170 can be located to the right of the bottom end of the link 191, and the top end of the support 170 can be located to the left of the top end of the link 191, so that the support 170 and the link 191 can be crossed in X shape in the projection on the vertical plane perpendicular to the first horizontal direction X. Wherein, the first horizontal direction X can be perpendicular to the second horizontal direction Y, and the second horizontal direction Y can be approximately the left-right direction of the lifting table 100.

[0068] In some embodiments, the base 110 or the table board assembly 130 can be provided with a strip-shaped slot extending along the second horizontal direction Y, and the moving piece 193 can be movably installed in the strip-shaped slot, so that the strip-shaped slot can provide a more accurate moving direction for the moving piece 193, and the inner wall of the strip-shaped slot can limit the movement of the moving piece 193, which helps the second support mechanism 190 to abut more stably between the base 110 and the table board assembly 130, so as to further improve the shaking condition of the table board assembly 130.

[0069] In some embodiments, the moving piece 193 is a roller, the roller is rollably connected to one of the base 110 or the table board assembly 130, and the link 191 is rotatably connected between the other one of the base 110 or the table board assembly 130 and the roller, the roller is used to move relative to the base 110 or the table board assembly 130 when rolling, and when the table board assembly 130 is lifted relative to the base 110, the link 191 can push the rolling piece to roll on the base 110 or the table board assembly 130 when rotating, so as to reduce the sliding friction, which helps the link 191 to rotate more smoothly, so as to help the table board assembly 130 to lift more smoothly.

[0070] As an example, the roller is rollably installed in the strip-shaped slot.

[0071] Please refer to Figure 3 and Figure 5 In some embodiments, the moving piece 193 can be a sliding block 1931, the sliding block 1931 is slidably connected to one of the base 110 or the table board assembly 130, and the link 191 is rotatably connected between the other one of the base 110 or the table board assembly 130 and the sliding block 1931, so that when the table board assembly 130 is lifted relative to the base 110, the link 191 can push the sliding block 1931 to slide when rotating, so that the link 191 can stably rotate.

[0072] The base 110 or the table board assembly 130 can be provided with a sliding groove 111 extending along the second horizontal direction Y, and the sliding block 1931 is at least partially slidably installed in the sliding groove 111, and the link 191 is connected to the part of the sliding block 1931 exposed to the sliding groove 111. It can be understood that the sliding groove 111 in the present embodiment can be the strip-shaped slot in the above-mentioned embodiments.

[0073] The inner wall of the slide 111 can also restrict the movement of the slider 1931 to further improve the wobbling of the table assembly 130, as described in the following embodiments.

[0074] In some embodiments, the slide 111 includes a first inner wall 1111, a second inner wall 1113, a third inner wall 1115, and an opening 1119. The opening 1119 and the third inner wall 1115 are arranged opposite to each other at a distance. The first inner wall 1111 and the second inner wall 1113 may be arranged opposite to each other at a distance and extend from the opening 1119 to the third inner wall 1115, respectively.

[0075] Among them, such as Figure 3 As shown, the inner wall 1111 of the first groove and the inner wall 1113 of the second groove can be arranged opposite each other at a distance along the vertical direction Z. The inner wall 1113 of the second groove can be located above the inner wall 1111 of the first groove. The groove opening 1119 and the inner wall 1115 of the third groove can be distributed at a distance along the first horizontal direction X. The slider 1931 can at least slidably contact the inner wall 1111 of the first groove and the inner wall 1113 of the second groove. Thus, the inner walls 1111 of the first groove and the inner wall 1113 of the second groove can limit the vertical movement of the slider 1931, which helps to prevent the slider 1931 from shaking up and down. This can further improve the shaking situation of the table assembly 130 and make the table assembly 130 more stable.

[0076] It should be noted that in this embodiment, the slider 1931 may slide to contact the inner wall 1115 of the third groove, or it may not contact the inner wall of the groove.

[0077] As an example, the cross-sectional shape of the slide 111 can be approximately rectangular. When the support 170 causes the table assembly 130 to rise relative to the base 110, the connecting rod 191 rotates, causing the slider 1931 to slide along the second horizontal direction Y towards the side closer to the bottom end of the support 170; when the support 170 causes the table assembly 130 to fall relative to the base 110, the connecting rod 191 rotates, causing the slider 1931 to slide along the second horizontal direction Y towards the side farther from the bottom end of the support 170.

[0078] In some embodiments, the first groove inner wall 1111 and the second groove inner wall 1113 may also be arranged opposite each other at a distance along the first horizontal direction X, and the groove opening 1119 and the third groove inner wall 1115 may be arranged opposite each other at a distance along the vertical direction Z. The groove opening 1119 is located above the third groove inner wall 1115, and the slider 1931 is slidably in contact with the third groove inner wall 1115, so that the third groove inner wall 1115 can support the slider 1931 in the vertical direction Z to support the connecting rod 191 and the table assembly 130.

[0079] The slider 1931 can slidably contact at least one of the first slot inner wall 1111 and the second slot inner wall 1113, the distance between the first slot inner wall 1111 and the second slot inner wall 1113 gradually decreases in the direction of the third slot inner wall 1115 to the slot opening 1119, so that the first slot inner wall 1111 and / or the second slot inner wall 1113 can cooperate with the third slot inner wall 1115 to limit the up and down of the slider 1931, which helps to avoid the up and down of the slider 1931, thereby further improving the shaking condition of the table board assembly 130, and making the table board assembly 130 more stable.

[0080] As an example, the cross-sectional shape of the sliding groove 111 can be approximately trapezoidal.

[0081] Please refer to Figure 2 , Figure 3 and Figure 5 In some embodiments, the number of sliding grooves 111 can be two, and the two sliding grooves 111 can be distributed along the first horizontal direction X.

[0082] The second support mechanism 190 can further include an intermediate rod 195, the number of sliders 1931 can be two, each slider 1931 is slidably installed in a sliding groove 111, the intermediate rod 195 is rotatably connected between the two sliders 1931, and the bottom end of the connecting rod 191 can be fixedly connected to the intermediate rod 195, so that the connecting rod 191 can be indirectly connected to the two sliders 1931 by being connected to the intermediate rod 195, the intermediate rod 195 can disperse the force transmitted from the connecting rod 191 to the two sliders 1931, so as to more dispersedly transmit the force to the base 110, which helps to more stably support the table board assembly 130, and the intermediate rod 195 also helps to make the contact force between the slider 1931 and the inner wall of the sliding groove 111 more uniform, improving the smoothness of the movement of the slider 1931.

[0083] As an example, the slot openings 1119 of the two sliding grooves 111 can be distributed along the first horizontal direction X and oppositely arranged. The intermediate rod 195 can be connected to the two sliders 1931 and located between the slot openings 1119 of the two sliding grooves 111. The rotation axis of the intermediate rod 195 can be arranged along the first horizontal direction X.

[0084] The connecting rod 191 can be fixedly connected to the intermediate rod 195 by welding, clamping or through a fixing member, which helps to avoid relative movement between the connecting rod 191 and the intermediate rod 195, so that the intermediate rod 195 and the connecting rod 191 can cooperate to more stably support the table board assembly 130. The fixing member can adopt a bolt, a screw, a rivet or other fixing structure,

[0085] In other embodiments, the number of the sliding grooves 111 can be two, the number of the sliding blocks 1931 can still be one, and the two ends of the sliding block 1931 along the first horizontal direction X can be slidably installed in one of the sliding grooves 111 respectively, and the connecting rod 191 can be rotatably connected to the sliding block, so that the intermediate rod 195 is not required to be arranged, and only one sliding block 1931 is required to be arranged to more evenly transmit the force transmitted from the connecting rod 191 to the base 110, which helps to more stably support the table board assembly 130, and the contact force between the sliding block 1931 and the inner walls of the two sliding grooves 111 is more uniform, and the smoothness of the movement of the sliding block 1931 is improved.

[0086] In some embodiments, the bottom end of the support 170 can be rotatably connected to the base 110, and the top end of the support 170 can be rotatably connected to the table board assembly 130, so that when the table board assembly 130 descends, the support 170 can simultaneously rotate relative to the table board assembly 130 and the base 110, and the table board assembly 130 can be closer to the base 110 when descending, so that the table board assembly 130 can have a larger lifting stroke relative to the base 110, and the lifting performance of the lifting table 100 is improved.

[0087] As an example, the rotation axis of the bottom end of the support 170 and the rotation axis of the top end of the support 170 can both be arranged along the first horizontal direction X.

[0088] In some embodiments, the support 170 is an electric support 170, so that the user does not need to manually lift the support 170, and the convenience of using the lifting table 100 is improved.

[0089] The electric support 170 can include a power member 171, a sliding seat 173, and a push rod 175.

[0090] The power member 171 can be connected to the sliding seat 173, the push rod 175 can be telescopically connected to the sliding seat 173, and the driving member can be drivingly connected to the push rod 175, so that the driving member can drive the push rod 175 to extend or retract relative to the sliding seat 173.

[0091] One of the sliding seat 173 or the push rod 175 is connected to the base 110, and the other of the sliding seat 173 or the push rod 175 is connected to the table board assembly 130, so that when the push rod 175 extends relative to the sliding seat 173, the table board assembly 130 can be pushed away from the base 110 to realize the lifting of the table board assembly 130, and when the push rod 175 retracts relative to the sliding seat 173, the table board assembly 130 can be driven to approach the base 110 to realize the descent of the table board assembly 130.

[0092] As an example, the bottom end of the sliding seat 173 can be rotatably connected to the base 110, and the top end of the push rod 175 can be rotatably connected to the table board assembly 130.

[0093] As another example, the top end of the sliding seat 173 is rotatably connected to the table board assembly 130, and the bottom end of the push rod 175 is rotatably connected to the base 110.

[0094] It should be noted that when the sliding seat 173 is connected to the table board assembly 130, the sliding seat 173 can be connected to the bottom surface of the table board assembly 130, and the power member 171 can also be located on the bottom surface of the table board assembly 130, so as to achieve the effect of hiding the sliding seat 173 and the power member 171, and help to improve the aesthetics of the lifting table 100.

[0095] The power member 171 is drivingly connected to the push rod 175 for driving the push rod 175 to extend and retract relative to the sliding seat 173 to drive the table board assembly 130 to move up and down relative to the base 110, so as to adjust the distance between the table board assembly 130 and the base 110 in the vertical direction Z, so that the extension and retraction of the push rod 175 can be driven by the power member 171 to control the lifting movement of the table board assembly 130 relative to the base 110, which helps to more conveniently adjust the distance between the table board assembly 130 and the base 110.

[0096] Specifically, the power member 171 can be drivingly connected to the push rod 175, and the power member 171 can be used to drive the push rod 175 to extend and retract relative to the sliding seat 173, and the extension and retraction of the push rod 175 relative to the sliding seat 173 can drive the table board assembly 130 to move up and down relative to the base 110, so as to adjust the distance between the table board assembly 130 and the base 110 in the vertical direction Z.

[0097] The driving connection of the power member 171 to the push rod 175 can also be used to maintain the distance between the table board assembly 130 and the base 110 by maintaining the position of the push rod 175 relative to the sliding seat 173, so as to lock the table board assembly 130 at a desired position, facilitating the user to use the table board assembly 130.

[0098] As an example, the power member 171 can have a self-locking function, and the power member 171 can maintain the position of the push rod 175 relative to the sliding seat 173 by the self-locking function to maintain the distance between the table board assembly 130 and the base 110.

[0099] In some embodiments, the lifting table 100 can further include a control knob, the control knob can be connected to the table board assembly 130, the control knob can be electrically connected to the support 170, and the control knob can be used to control the support 170 to control the lifting movement of the table board assembly 130 relative to the base 110, so that the user can directly drive the lifting of the table board assembly 130 by turning the control knob, and the operation is more convenient.

[0100] As an example, the control knob can be installed on the bottom surface of the table board assembly 130 and located on the side along the second horizontal direction Y, so as to facilitate the user to operate the control knob.

[0101] The control knob can be a button, a dial knob, a rotary knob, or another control knob.

[0102] The number of control knobs can be one or two. When the number of control knobs is two, one of the control knobs can control the lifting of the tabletop assembly 130, and the other control knob can control the lowering of the tabletop assembly 130.

[0103] In some embodiments, the control knob can be electrically connected to the power member 171. The control knob can control the power member 171 to drive the telescopic rod to extend relative to the sliding base 173 and can drive the telescopic rod to retract relative to the sliding base 173.

[0104] Referring to Figure 2 and Figure 4 In some embodiments, the number of first support mechanisms 150 can be two. The two first support mechanisms 150 can be arranged opposite to each other along the first horizontal direction X, so that the two first support mechanisms 150 can respectively provide two support points for the tabletop assembly 130 along the first horizontal direction X, thereby improving the situation that the tabletop assembly 130 shakes back and forth.

[0105] The support device 170 and the connecting rod 191 can be arranged between the two first support mechanisms 150, so that the support device 170 and the connecting rod 191 can support the tabletop assembly 130 between the two first support mechanisms 150, to cooperate with the two first support mechanisms 150 to more stably support the tabletop assembly 130.

[0106] In some embodiments, the first support mechanism 150 can adopt a rhombic connecting rod support mechanism to improve stability.

[0107] Specifically, the first support rod 151 and the third support rod 155 can be arranged in parallel, and the second support rod 153 and the fourth support rod 157 can be arranged in parallel, so that the first support mechanism 150 can form a rhombic connecting rod support mechanism, which helps to more stably support the tabletop assembly 130.

[0108] As an example, the lengths of the first support rod 151, the second support rod 153, the third support rod 155, and the fourth support rod 157 can be substantially equal.

[0109] In some embodiments, the lifting table 100 can further include a connecting rod 210.

[0110] At least one connecting rod 210 can be connected between the first support rods 151 of the two first support mechanisms 150, so that the two first support rods 151 can rotate more synchronously, so that the two first support mechanisms 150 can move synchronously, which helps to improve the situation that the tabletop assembly 130 is unstable due to the asynchronous movement of the two first support mechanisms 150.

[0111] In some embodiments, at least one connecting rod 210 can be connected between the second support rods 153 of the two first support mechanisms 150, so that the two second support rods 153 can rotate synchronously, so that the two first support mechanisms 150 can move synchronously, which helps to improve the instability of the table board assembly 130 caused by the asynchronous movement of the two first support mechanisms 150.

[0112] In some embodiments, at least one connecting rod 210 can be connected between the third support rods 155 of the two first support mechanisms 150, so that the two third support rods 155 can rotate synchronously, so that the two first support mechanisms 150 can move synchronously, which helps to improve the instability of the table board assembly 130 caused by the asynchronous movement of the two first support mechanisms 150.

[0113] In some embodiments, at least one connecting rod 210 can be connected between the fourth support rods 157 of the two first support mechanisms 150, so that the two fourth support rods 157 can rotate synchronously, so that the two first support mechanisms 150 can move synchronously, which helps to improve the instability of the table board assembly 130 caused by the asynchronous movement of the two first support mechanisms 150.

[0114] Please refer to Figure 2 , Figure 6 and Figure 7 In some embodiments, the lifting table 100 can further include a first mounting block 230, which can be mounted to the base 110, and the first mounting block 230 can be provided with a first open slot, and the bottom end of the first support rod 151 and the bottom end of the second support rod 153 can be rotatably mounted in the first open slot, and can be rotatably connected to the first mounting block 230 through the rotating shaft.

[0115] It can be understood that a bearing can be further sleeved outside the rotating shaft, so that the bottom end of the first support rod 151 and the bottom end of the second support rod 153 can rotate more smoothly.

[0116] Similarly, the lifting table 100 can further include a second mounting block 250, which can be mounted to the table board assembly 130, and the first mounting block 230 can be provided with a second open slot. The top end of the third support rod 155 and the top end of the fourth support rod 157 can be rotatably mounted in the second open slot, and the specific rotating mode can refer to the mounting mode of the bottom end of the first support rod 151 and the bottom end of the second support rod 153 in the first mounting block 230, which will not be described again.

[0117] The side of the first open slot facing upward in the vertical direction Z and the opposite sides facing the second horizontal direction Y are both provided with openings, so as to avoid the interference of the slot wall of the first open slot with the rotation of the first support rod 151 and the second support rod 153.

[0118] The second opening slot is provided with openings along the sides facing the vertical direction Z downward and the opposite sides facing the second horizontal direction Y to avoid interference of the slot walls of the second opening slot with the rotation of the third support rod 155 and the fourth support rod 157.

[0119] Please refer to Figure 2 and Figure 6 In some embodiments, one of the first support rod 151 and the base 110 is provided with a first limiting hole 231, and the other is provided with a first limiting column 1513 which is slidably inserted into the first limiting hole 231, so that the hole walls of the first limiting hole 231 and the first limiting column 1513 can limit each other to limit the maximum rotation stroke of the first support rod 151 and improve the shaking of the first support rod 151.

[0120] As an example, as Figure 6 shown, the first support rod 151 can include a rod body and a first limiting column 1513, and the bottom end of the rod body is rotatably connected to the first opening slot of the first mounting block 230. The first limiting column 1513 can be protruded from the bottom end of the rod body. The first mounting block 230 can be provided with a first limiting hole 231 which is in communication with the first opening slot, and the first limiting column 1513 is slidably inserted into the first limiting hole 231, and the axial direction of the first limiting hole 231 can be along the first horizontal direction X. The rod body rotates synchronously with the first limiting column 1513, and the hole walls of the first limiting hole 231 can limit the maximum rotation stroke of the first support rod 151.

[0121] In addition, the first limiting column 1513 can slidably contact or indirectly contact the two hole walls of the first limiting hole 231 along the second horizontal direction Y, and the two hole walls can limit the shaking of the first limiting column 1513 along the second horizontal direction Y, so as to limit the shaking of the first support rod 151 along the second horizontal direction Y, which helps the first support mechanism 150 to more stably support the table board assembly 130 and further improves the shaking of the table board assembly 130.

[0122] As another example, the bottom end of the first support rod 151 can be provided with a first limiting hole 231, and the axial direction of the first limiting hole 231 can be along the first horizontal direction X. The first mounting block 230 can be protruded with a first limiting column 1513, which is located in the first opening slot and inserted into the first limiting hole 231. It can be understood that in this example, the first limiting column 1513 is fixed, and the first limiting hole 231 rotates with the rotation of the first support rod 151, so that the first limiting column 1513 can slide relative to the first limiting hole 231, and the first limiting column 1513 can limit the maximum rotation stroke of the first support rod 151 by abutting against the hole walls of the first limiting hole 231.

[0123] In addition, the first limiting column 1513 can contact or indirectly contact two hole walls of the first limiting hole 231 along the second horizontal direction Y, so that the first limiting column 1513 can limit the first supporting rod 151 from shaking along the second horizontal direction Y, help the first supporting mechanism 150 to support the table board assembly 130 more stably, and further improve the shaking condition of the table board assembly 130.

[0124] It should be noted that the first limiting column 1513 and the hole wall of the first limiting hole 231 can be in direct sliding contact or indirect sliding contact.

[0125] As an example, the lifting table 100 can further include a bearing, the first limiting column 1513 can be inserted into the inner ring of the bearing, the outer peripheral surface of the outer ring of the bearing can be in sliding contact with the hole wall of the first limiting hole 231, the first limiting column 1513 and the hole wall of the first limiting hole 231 can realize indirect sliding contact through rotation of the bearing, and the first limiting column 1513 and the hole wall of the first limiting hole 231 can limit the movement of each other through the bearing.

[0126] In some embodiments, one of the second supporting rod 153 and the base 110 is provided with a second limiting hole 233, and the other is provided with a second limiting column 1533, the second limiting column 1533 is slidably arranged in the second limiting hole 233, so that the hole wall of the second limiting hole 233 and the second limiting column 1533 can limit the movement of each other to limit the maximum rotation stroke of the second supporting rod 153, and can improve the shaking condition of the second supporting rod 153.

[0127] The arrangement and beneficial effects of the second limiting column 1533 and the second limiting hole 233 can refer to the arrangement of the first limiting column 1513 and the first limiting hole 231, and will not be repeated here.

[0128] It can be understood that the first mounting block 230 can be provided with the first limiting hole 231 and the second limiting hole 233 at the same time, or the first mounting block 230 can be provided with the first limiting hole 231 and the first limiting column 1513 at the same time, or the first mounting block 230 can be provided with the first limiting column 1513 and the second limiting column 1533 at the same time.

[0129] Please refer to Figure 2 and Figure 7 In some embodiments, one of the third supporting rod 155 and the table board assembly 130 is provided with a third limiting hole 251, and the other is provided with a third limiting column 1553, the third limiting column 1553 is slidably arranged in the third limiting hole 251, so that the hole wall of the third limiting hole 251 and the third limiting column 1553 can limit the movement of each other to limit the maximum rotation stroke of the third supporting rod 155, and can improve the shaking condition of the third supporting rod 155.

[0130] The arrangement and beneficial effects of the third limiting column 1553 and the third limiting hole 251 can refer to the arrangement of the first limiting column 1513 and the first limiting hole 231, and will not be repeated here.

[0131] It should be noted that in this embodiment, the third limiting column 1553 or the third limiting hole 251 arranged on the table board assembly 130 can be arranged on the second mounting block 250.

[0132] In some embodiments, one of the fourth support rod 157 and the table board assembly 130 is provided with a fourth limiting hole 253, and the other is provided with a fourth limiting column 1573, the fourth limiting column 1573 is slidably arranged in the fourth limiting hole 253, so that the hole wall of the fourth limiting hole 253 and the fourth limiting column 1573 can restrict each other to limit the maximum rotation stroke of the fourth support rod 157, and the shaking of the third support rod 155 can be improved.

[0133] The arrangement and beneficial effects of the fourth limiting column 1573 and the fourth limiting hole 253 can refer to the arrangement of the first limiting column 1513 and the first limiting hole 231, and will not be repeated here.

[0134] It should be noted that in this embodiment, the fourth limiting column 1573 or the fourth limiting hole 253 arranged on the table board assembly 130 can be arranged on the second mounting block 250.

[0135] Please refer to Figure 2 and Figure 6 In some embodiments, the first limiting hole 231 can be a circular arc hole, the center of the first limiting hole 231 can be located on the rotation axis of the bottom end of the first support rod 151, and the first limiting column 1513 and the hole wall of the first limiting hole 231 can be in sliding contact, so that the first limiting column 1513 can always contact the hole wall of the first limiting hole 231, which helps to further improve the shaking of the first support rod 151 along the second horizontal direction Y, and the first limiting column 1513 and the hole wall of the first limiting hole 231 can be in direct contact, which helps to reduce the structure of the bearing and reduce the manufacturing cost of the lifting table 100.

[0136] It should be noted that since the first limiting hole 231 is a circular arc hole, the hole wall of the first limiting hole 231 is arranged in an arc shape, and when the first limiting column 1513 and the hole wall of the first limiting hole 231 are in sliding contact, the hole wall of the limiting hole and the first limiting column 1513 can also limit the up and down shaking of the first support rod 151 along the vertical direction Z.

[0137] As an example, the second limiting column 1533 can slide along at least one of the two opposite hole walls of the first limiting hole 231 along the second horizontal direction Y.

[0138] It can be understood that the two opposite hole walls of the first limiting hole 231 arranged along the vertical direction Z can also limit the first limiting column 1513, so as to limit the maximum rotation stroke of the first support rod 151, which helps to avoid affecting the supporting effect due to the large rotation angle of the first support rod 151 when the lifting table 100 rises, and when the lifting table 100 descends to the lowest position relative to the base 110, the first limiting column 1513 and the hole wall of the first limiting hole 231 abut each other, so as to better support the table board assembly 130.
