DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Embodiment one: please refer to Figures 1-6 The utility model provides a technical scheme: wood-imitating lifting table, include: bottom support ring 1 and scissor support 4, bottom support ring 1 between being equipped with bottom support frame 2, bottom support ring 1 passes through annular structure and forms closed support base, cooperate the frame type design of bottom support frame 2, significantly increase the contact area with ground.

[0024] Bottom support frame 2 top four corners are equipped with guide groove 3, and guide groove 3 between being equipped with scissor support 4, guide groove 3 is with four corners symmetry distribution and restricts the folding track of scissor support 4, passes through linear sliding pair and limits its movement direction. Scissor support 4 adopts X type cross hinged structure, realizes height adjustment through connecting rod angle change in the process of lifting, and its symmetry design cooperates guide groove 3 and can automatically balance the stress of both sides, avoids the jam or inclination caused by one-sided partial load.

[0025] Scissor support 4 top is equipped with table support 10, and table support 10 top is equipped with table panel 13, and table support 10 is fixed with table panel 13 through multiple-point bolt connection, forms high-rigidity bearing platform. Or table panel 13 is fixed on table support 10 through other existing fixed mode.

[0026] The bottom of the desktop support 10 is centrally provided with a central connecting rod 12, one end of the central connecting rod 12 is provided with a gas cylinder 11, the other end of the gas cylinder 11 is connected with one side of the desktop support 10, the bottom of the central connecting rod 12 is centrally provided with a three-connecting-rod 6, the two ends of the scissor support 4 are provided with a connecting shaft 5, and the two ends of the three-connecting-rod 6 are connected with the connecting shaft 5. The connecting shaft 5 is used as the hinged joint of the two ends of the scissor support 4, and converts the dispersed joint movement into synchronous rotation. The three-connecting-rod 6 is hinged at the two ends with the connecting shaft 5, and forms a geometrically closed force transmission chain. When the gas cylinder 11 drives the central connecting rod 12 to move through extension and retraction, the three-connecting-rod 6 decomposes the force into a component force along the axis of the scissor support 4, and makes the force of each joint uniform through the parallelogram effect. Compared with the traditional gas cylinder which changes the inclination angle in the vertical direction along with the lifting of the scissor support, the design can maintain force balance and inhibit the shaking amplitude from exceeding 60% at the extreme height, such as full expansion or full folding state.

[0027] The bottom support ring 1 is provided with a support rod 7 at the top, the top of the support rod 7 is provided with an upper support ring 8, and the outer contour size of the upper support ring 8 is smaller than that of the desktop support 10. When the scissor support 4 drives the desktop support 10 to descend, the upper support ring 8 remains a fixed height along with the support rod 7. When the desktop support 10 is lowered to the lowest position, the bottom edge thereof is in contact with the upper support ring 8, thereby forming a physical stop point and preventing further descent. When the control system of the gas cylinder 11 fails, the upper support ring 8 provides passive limiting to prevent the scissor support 4 from being excessively compressed due to gravity or misoperation, and to avoid structural damage.

[0028] The outer periphery of the desktop support 10 is provided with a desktop bottom frame 9, and the desktop bottom frame 9 forms a closed frame. The middle part of the desktop support 10 and the central connecting rod 12 are rotationally connected, one side of the outer wall of the desktop bottom frame 9 is provided with a gas cylinder control valve 15, and the gas cylinder 11 is a double-pipe controllable gas spring. The gas cylinder 11 is a double-pipe controllable gas spring, and the damping is adjusted through a rotary valve.

[0029] The bottom of the central connecting rod 12 is centrally fixed with the middle connecting rod of the three-connecting-rod 6, and the three-connecting-rod 6 is rotationally connected with the connecting shaft 5. The gas cylinder 11 directly drives the middle connecting rod 12 to rotate through extension and retraction, drives the middle part of the three-connecting-rod 6 to rotate through the fixed connection between the middle connecting rod 12 and the middle part of the three-connecting-rod 6, and thus drives the two ends of the three-connecting-rod 6 to converge or move away from the middle part, so as to realize the lifting of the scissor support 4.

[0030] The connecting shaft 5 is arranged between the top and the bottom of the scissor support 4, and the middle of the three-connecting-rod 6 located at the bottom is rotationally connected with the bottom support frame 2. The bottom three-connecting-rod 6 increases the stability of the lifting mechanism.

[0031] The bottom support ring 1 is provided with leveling foot screws 14, and the leveling foot screws 14 are at least three. The leveling foot screws 14 are used for adjusting the level and stability of the lifting table, especially in the case of uneven ground. The bottom support ring 1 can be a ring structure as the bottom support of the whole device, and the foot screws are used for adjusting the height to ensure the stability of the device. Three or more foot screws can allow more flexible adjustment to ensure that the device can be stably placed under different ground conditions.

[0032] In the wooden lifting table, when in use, the horizontally arranged air cylinder 11 is perpendicular to the lifting direction of the scissor support 4, avoiding lateral component force, so that the lifting process is more stable. The three-link mechanism 6 uniformly disperses force to each joint through geometric constraints, further inhibiting shaking, and can keep the table stable even under high load or extreme height. Moreover, the linear extension and retraction movement of the air cylinder 11 and the rotation of the three-link mechanism 6 are directly coupled through the hinge point to form a determined mechanical linkage relationship. This design makes the lifting track of the scissor support 4 more controllable, and the synchronization error on both sides is greatly reduced, avoiding the problem of different synchronization of the two ends of the traditional lifting structure, and ensuring that the two ends of the table are horizontal and stable during lifting.

[0033] Embodiment two: please refer to Figures 1-6 The utility model provides a technical scheme: wooden lifting table, in this embodiment, other with embodiment one is same, in this embodiment, provide the following application scene reference: the lifting table can be reduced to 31cm at least, can be above 75cm at least, the movable stroke is long, and can stop at any height; the lifting table can be used as afternoon tea scene when being raised to 45cm height. The lifting table can be used as dining furniture when being raised to 75cm height, satisfies user multiple practical space. The bottom support ring 1 and the upper support ring 8 of the lifting table can be provided with some rattan or imitation rattan, increase the appearance of table, and the circle surrounded by rattan can store appliances such as ice bucket, which has the function of temporary storage.

[0034] When the lifting table is lowered to the lowest point, a cushion can be placed on the table top, and in combination with other products, it can be used as a sun bed. In this embodiment, the elliptical table top is still continued, which has unique advantages in space utilization and aesthetics. The lifting table is placed in the middle, and the half-round foot stools with and without shelves on both sides are matched with it. The inner arc of the half-round foot stools matches the elliptical arc on both sides of the lifting table. When needed, the half-round foot stools can be pulled apart to be used as a combination of a table and a stool.

[0035] Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
