Specific embodiment
The utility model is further described with reference to the accompanying drawing.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, hydraulic support reversal valve handle self-locking device, including lid shell 1, handle 2, rotatable parts 3
With shaft 7, handle 2 passes through rotatable parts 3 and shaft 7 is hinged；Handle 2 can be rotated by rotatable parts 3 around shaft,
And then realize the function of commutation；Rotatable parts 3 include handle positioning sleeve 5, and handle positioning sleeve 5 is ladder shaft-like, handle positioning sleeve 5
One end is provided with handle positioning sleeve otic placode 51, and there are two be arranged symmetrically in 5 front end of handle positioning sleeve, hand to handle positioning sleeve otic placode 51
Handle positioning sleeve otic placode 51 is hinged by pin shaft and shaft 7；The hole of 5 inner end of handle positioning sleeve is stepped hole 52, and 2 front end of handle is equipped with
The baffle ring 21 of annular, 2 front end of handle are threaded through in handle positioning sleeve 5, step edge and hand in the stepped hole 52 of handle positioning sleeve 5
