Due to the different sizes and shapes of customized desktops, higher requirements are placed on the adaptability of parts. For example, currently, lift tables mainly include There are two types of straight desktops and L-shaped desktops. Most of the lift tables sold on the market are of a single shape. The internal parts are assembled in a single way and can only be assembled into one shape. When the factory produces and processes the parts, , taking into account the need to meet the requirements of as many styles as possible, while also considering the requirement to reduce costs, and cannot meet customization requirements.

实施例二Embodiment 2
如图10所示，与实施例一不同的是，本实施例中矩形板体的拼接方式不同，导致第二传动轴位于L型的桌板中较短的边下方，在装配时，需要第二传动轴将长度调短后再装配，此种方式与实施例一中的电动升降桌使用场景相同，根据使用场地的尺寸进行选择。As shown in Figure 10, the difference from Embodiment 1 is that the rectangular plates in this embodiment are spliced differently, resulting in the second transmission shaft being located below the shorter side of the L-shaped table. During assembly, a third drive shaft is required. The length of the second transmission shaft is shortened before assembly. This method is the same as the use scenario of the electric lift table in Embodiment 1, and is selected according to the size of the use site.
实施例三Embodiment 3
如图11所示，与实施例一不同的是，本实施例中仅采用两块矩形板体进行装配，属于长桌的一种，本实施例中的升降立柱为偶数个，且具体为2个，所以，仅需采用一个第二传动轴进行传动即可，设置一套驱动机构进行驱动，从而实现升降效果，成本低且运行稳定。As shown in Figure 11, what is different from Embodiment 1 is that only two rectangular plates are used for assembly in this embodiment, which is a type of long table. There are an even number of lifting columns in this embodiment, and specifically 2 Therefore, only one second transmission shaft is needed for transmission, and a set of driving mechanism is provided for driving, thereby achieving the lifting effect, low cost and stable operation.
实施例四Embodiment 4
如图12所示，与实施例一不同的是，本实施例中采用三块矩形板体拼接成一个长桌，由于长度较长，采用三个升降立柱2的方式，本实施例中的升降立柱为奇数个，且具体为3个，所以，需采用一个第二传动轴带动相邻两个升降立柱进行升降，剩余一个升降立柱单独采用一套驱动机构进行驱动，从而实现升降效果，装配简单且运行稳定。As shown in Figure 12, what is different from Embodiment 1 is that three rectangular plates are used in this embodiment to form a long table. Due to the long length, three lifting columns 2 are used. There are an odd number of columns, specifically 3. Therefore, a second transmission shaft needs to be used to drive the two adjacent lifting columns to lift. The remaining lifting column is driven by a separate driving mechanism to achieve the lifting effect and simple assembly. And the operation is stable.
本发明提供的技术方案中，还包括4条升降立柱2以上的方案，鉴于实际生产生活中使用的不是很多，且升降立柱2的使用数量多了，对升降的同步性要求更加严格，所以，本发明中不再一一列举，但上述方案扔落入本申请中的保护范围。The technical solution provided by the present invention also includes a solution with more than 4 lifting columns 2. In view of the fact that not many are used in actual production and life, and the number of lifting columns 2 is increased, the requirements for the synchronization of lifting are more stringent, so, The present invention will not enumerate them one by one, but the above solutions fall within the protection scope of this application.
本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。Those skilled in the industry should understand that the present invention is not limited by the above embodiments.
