Tennis rack jacking process
The invention discloses a jacking process of a tennis frame, which comprises the step of constructing a jacking system of the tennis frame to construct the jacking system of the tennis frame capable of reducing the load of a pull rod. In the constructed jacking system of the tennis frame, the telescopic lifting auxiliary part lifts the jacking frame in the sunken groove of the jacking seat, the pull rod of the jacking part carries out auxiliary stress in the lifting process of the jacking frame, the load borne by the pull rod is reduced, and in the jacking process of the jacking frame, the pull rod is not prone to falling off. When the pull rod, hinged to the jack, of the jacking frame is subjected to fatigue damage, the four lifting auxiliary pieces can support the four feet at the bottom of the jacking frame at the same height, and the problem that when a single jack is installed in the middle of the jacking base, the four feet at the bottom of the jacking frame cannot be supported at the same height when the pull rod is subjected to fatigue damage is solved.
本申请公开了一种网球架的顶升工艺，包括：通过完成网球架的顶升系统搭建步骤，构建出能减少拉杆受载的网球架的顶升系统。构建的网球架的顶升系统中，可伸缩的升降辅助件在顶升座下沉的凹槽内对应顶升架进行提升，顶升件的拉杆在顶升架提升的过程进行辅助受力，降低了拉杆所受载荷，在顶升架顶升架顶升过程时，顶升架铰接千斤顶的拉杆出现疲劳损坏时，四个升降辅助件能对顶升架底部四脚进行同一高度支撑，解决了顶升座中部安装单个千斤顶在拉杆出现疲劳损坏时不能对顶升架底部四脚进行同一高度支撑的问题。
