The buffer 14 is internally provided with a shock absorbing spring to reduce secondary damage to the user caused by inertia during assembly. The stopper 12 is used for stopping the fixing protrusion of the lower surface of the lower connecting plate 5 of the adjustable lifting device 2 (not shown in the drawing, two groups are provided, two are disposed near the front end, and two are disposed near the rear end) , corresponding to the number of stops 12), for the limit after assembly. When the multi-functional wheelchair is used in combination, the lower connecting plate 5 of the adjustable lifting device 2 is slidably inserted along the sliding slot 13 from the rear end of the base 1 toward the front end under the limit of the two sliding grooves 13. When the fixing protrusion of the lower surface of the lower link plate 5 acts on the guide slope of the lock block 15, the lock block 15 is pressed downward, and after the fixing protrusion of the rear end passes over the uppermost end of the lock block 15, the lock block 15 passes the self-locking.

When the combined multifunctional wheelchair is disassembled, pressure is applied to the lock block 15, and the lock block 15 is pressed down to the upper surface to be flush with the upper surface of the lower link plate 5, and the elastic force of the buffer 14 is directed in the opposite direction of the assembly, so that the adjustable lift The device 2 is released from the locking connection with the base 1, and then the adjustable lifting device 2 is dragged by an external force to complete the splitting. This structure makes the splitting process time-saving and labor-saving, and the operation can be completed by a single person. Specifically, when splitting, the user presses down with the foot (or presses down with other working tools) to unlock the crossbar portion of the frame 19, applying downward pressure to the unlocking frame 19, thereby overcoming the self-locking spring 18. The spring force causes the lock block 15 to be pressed down to the upper surface to be flush with the upper surface of the lower gusset 5, and the elastic force of the damper 14 is opposite to the assembly direction, so that the adjustable lifting device 2 is released from the locking connection with the base 1 (ie, disassembly) In the combined state), the adjustable lifting device 2 is dragged by an external force to complete the splitting. This pedal-type unlocking structure can reduce the working intensity of the splitting personnel, and is convenient and reliable.

[0093] 一种省力型短行程的连杆结构, 可以用于桌椅等物品的升降, 尤其适合用于空 间小的产品结构。 具体结构为: 一种省力型短行程的连杆结构包括上联接板 ( 在图 1-9的实施例中为坐板) 、 下联接板, 及铰接于上联接板与下联接板之间的 支撑结构; 所述的支撑结构包括前支撑杆组件、 后支撑杆组件; 还包括用于驱 动支撑结构旋转的驱动机构, 所述驱动机构产生直线运动, 以使上联接板、 前 支撑杆组件、 下联接板和后支撑杆组件形成的平行四边形机构处于展开状态或 收纳状态; 所述的前支撑杆组件包括左前支撑杆和右前支撑杆, 所述的后支撑 杆组件包括左后支撑杆和右后支撑杆; 所述驱动机构为电动伸缩杆; 电动伸缩 杆的固定端与下联接板铰接, 电动伸缩杆的活动端通过联接头套设于推轴外圈 , 推轴两端各设有一个滚轮, 滚轮在左前支撑杆、 右前支撑杆上所设的滚轮槽 内滚动, 下联接板还设有过渡支撑转轴, 过渡支撑转轴两端与下联接板铰接, 过渡支撑转轴近两端处设有与其轴线相垂直的过渡支撑臂, 过渡支撑臂顶端设 有上滚轴, 推轴的两端还分别枢接于过渡支撑臂的中段。 上升过程中, 滚轮外 表面与滚轮槽接触, 电动伸缩杆的活动端伸出时, 带动滚轮在滚轮槽内滚动, 将上联接板、 前支撑杆组件、 下联接板和后支撑杆组件所组成的平行四边形撑 起。 当可调式升降装置上升到预定高度 (近于最大打开状态) 时, 滚轮脱离滚 轮槽, 不产生支撑力, 由过渡支撑臂顶端的上滚轴与滚轮槽的两侧边缘处相接 触来产生支撑力, 此时的力臂变大, 第一电推杆所受到的反作用力变小, 从而 使得可调式升降装置在打开状态能够更加地稳定。 这样的支撑结构优点在于可 以在可调式升降装置上升过程中加大初始受力, 并缩短电推杆的行程, 电推杆 在最大状态时又受力小, 保证各构件的结构稳定性, 增长使用寿命。 其中的上 滚轴优选采用阶梯状结构, 即两端的直径小于中间的部分。  [0093] A labor-saving short-stroke link structure can be used for lifting and lowering items such as tables and chairs, and is particularly suitable for a product structure having a small space. The specific structure is: A labor-saving short-stroke link structure includes an upper coupling plate (in the embodiment of FIGS. 1-9, a seat plate), a lower coupling plate, and a hinge between the upper coupling plate and the lower coupling plate. The support structure includes a front support bar assembly and a rear support bar assembly; and a drive mechanism for driving the rotation of the support structure, the drive mechanism generates a linear motion to make the upper link plate, the front support bar assembly, The parallelogram mechanism formed by the lower link plate and the rear support bar assembly is in an unfolded state or a stowed state; the front support bar assembly includes a left front support bar and a right front support bar, and the rear support bar assembly includes a left rear support bar and a right The driving mechanism is an electric telescopic rod; the fixed end of the electric telescopic rod is hinged with the lower connecting plate, and the movable end of the electric telescopic rod is set on the outer ring of the pushing shaft through the coupling head, and one roller is arranged at each end of the pushing shaft The roller rolls in the roller groove provided on the left front support bar and the right front support bar, and the lower link plate is further provided with a transition support shaft, and the transition support shaft The end is hinged to the lower connecting plate, and a transition support arm perpendicular to the axis is disposed at the proximal end of the transition support shaft, and the top end of the transition support arm is provided with an upper roller, and the two ends of the push shaft are respectively pivotally connected to the middle portion of the transition support arm . During the ascent, the outer surface of the roller is in contact with the roller groove. When the movable end of the electric telescopic rod is extended, the roller is driven to roll in the roller groove, and the upper connecting plate, the front supporting rod assembly, the lower connecting plate and the rear supporting rod assembly are formed. The parallelogram is propped up. When the adjustable lifting device is raised to a predetermined height (near the maximum opening state), the roller is disengaged from the roller groove, and no supporting force is generated, and the upper roller at the top end of the transitional support arm contacts the two side edges of the roller groove to generate support. The force, the force arm at this time becomes larger, and the reaction force received by the first electric push rod becomes smaller, so that the adjustable lifting device can be more stable in the open state. The advantage of such a support structure is that the initial force can be increased during the ascending lifting device, and the stroke of the electric push rod can be shortened. When the electric push rod is in the maximum state, the force is small, and the structural stability of each member is ensured. Service life. The upper roller preferably has a stepped structure, that is, the diameter of both ends is smaller than the intermediate portion.
