The invention provides an inflation and deflation connector for an undercarriage buffer strut. The inflation and deflation connector comprises an ejector rod, a pin and a shell, wherein the pin is inserted into the ejector rod; gas enters or flows out from a conical nozzle of the shell, and the undercarriage buffer strut is inflated and deflated through the ejector rod; a pressure gauge is also arranged on the shell and is used for measuring the pressure in the joint; the inflation and deflation connector for the undercarriage buffer strut is small, exquisite, flexible, convenient to use, easy to operate, stable and reliable in performance and capable of achieving rapid inflation and deflation and accurate gas measurement; meanwhile, inflation and deflation conversion of buffer struts of various large-size helicopters can be achieved, the gas pressure of the buffer struts can be accurately measured, nodes of novel-size development tasks are guaranteed, and the test efficiency is greatly improved.

    本发明提供了一种起落架缓冲支柱充放气接头,包括:顶杆、插接在所述顶杆上的销子以及壳体;其中,气体从所述壳体的锥形管嘴进入或流出,通过所述顶杆为起落架缓冲支柱进行充放气;并且所述壳体上还设置有压力表,用于测量接头内的压力;本发明的起落架缓冲支柱充放气接头,小巧、灵便、使用便捷、操作简单、性能稳定可靠,可实现快速充放气、准确测量气体;同时,可以满足对各大型号直升机缓冲支柱的充放气转换和准确测量缓冲支柱气体压力,保障了新型号研制任务的节点,大大提高了试验效率。
