The invention relates to a locking structure of a hospital bed hanger, including a locking seat, a locking pin, a locking handle, a crankshaft, a combination pin, a shaft bush, a locking block, a locking plate, a shaft sleeve, a flange shaft sleeve, an external circlip, a button spring and a safety locking block.The locking seat is fixedly installed on the crossbeam of the hospital bed hanger, the locking pin is horizontally fixed through the locking seat, one end of the crankshaft is fixed on the locking handle, the combined pin is inserted on the other end of the crankshaft along the radial direction, the shaft bush, the upper part of the locking block, the locking plate, the shaft bush, the flange shaft bush, the external circlip, the button spring and the safety locking block are successively sleeved in the middle of the crankshaft.Because the crankshaft fixed on the locking handle can drive the locking block to swing and is clamped on the locking pin installed on the locking seat, it is easy to disassemble and assemble. Moreover, the invention is also provided with a button spring and a safety locking block, which can effectively prevent the separation of the locking block and the locking pin, and the connection is reliable and safe.本創作係有關一種病床吊架的鎖接結構，包括鎖緊座、鎖緊銷、鎖緊把手、曲軸、結合銷、軸襯套、鎖緊塊、鎖板、軸套、法蘭軸套、外部卡簧、按鈕彈簧、安全鎖緊塊。所述的鎖緊座固定安裝在病床吊架的橫樑上，鎖緊銷橫向固定穿置在鎖緊座上，曲軸的一端固定在鎖緊把手上，結合銷沿徑向插置在曲軸的另一端，軸襯套、鎖緊塊上部、鎖板、軸套、法蘭軸套、外部卡簧、按鈕彈簧、安全鎖緊塊依次套接在曲軸的中部。由於本創作固定於鎖緊把手上的曲軸可驅動鎖緊塊擺動而卡接在安裝於鎖緊座上的鎖緊銷上，易於拆裝，且本創作還設有按鈕彈簧和安全鎖緊塊，可有效防止鎖緊塊與鎖緊銷的脫離，連接可靠、安全性高。
