In vivo, when concave mouth go to mandrel ends to it is corresponding when mandrel ends be caught in groove handle fixed, pass through machine
The mode of tool replaces magnet suction type in the prior art, and to the fixation high reliablity of handle, and structure is simple, processing side
Just.
Detailed description of the invention
Fig. 1 is that the structure of the handle self-locking device in one embodiment of concrete closed guard gate of the utility model a kind of is shown
It is intended to；
Fig. 2 is the partial enlarged view in Fig. 1 at A.
Specific embodiment
The embodiment of concrete closed guard gate of the utility model a kind of as Figure 1-Figure 2, including door body and is set to door
Handle self-locking device on body, handle self-locking device include the handle 1 being rotatably dispose in door body by shaft 2 and are set to door
Installation cylinder 4 on body, along its axis direction guiding movement and elasticity is equipped with mandril 5 in installation cylinder 4, mandril 5 has court
To the mandrel ends 6 of shaft, annular protrusion 3 is provided in shaft 2, the outer peripheral surface of annular protrusion 3 is provided with to be blocked with mandrel ends 6
The groove 7 of sincere cooperation, groove 7 and mandrel ends 6 form fixing structure, and installing to be provided on cylinder prevents mandril from deviating from mounting cylinder
The position limiting structure of body.Mandrel ends 6 are spherical structure, and a trough wall surface of groove 7 is lozenges 13, and the setting of lozenges 13 can
So as to facilitate skidding off for mandrel ends in rotating shaft, and another cell wall of groove 7 then may be used for the flat face perpendicular to slot bottom
