Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 4, in an embodiment of the present invention, a mechanical lock device includes a mechanism panel 1, a mechanical lock assembly and an installation housing 2 are installed on an upper end surface of the mechanism panel 1, an energy storage shaft 3 is rotatably installed in the middle of the installation housing 2, and a manual operation shaft 4 is fixedly installed on an upper end of the energy storage shaft 3.

In this embodiment, the mechanical lock assembly includes a mechanical lock mounting plate 5, a mechanical lock 6, a telescopic shaft 7 and an operation knob 8, the mechanical lock mounting plate 5 is fixedly mounted beside the upper end surface mounting housing 2 of the mechanism panel 1 by screws, the mechanical lock 6 is fixedly mounted on the upper end surface of the mechanical lock mounting plate 5 by bolts, the telescopic shaft 7 is slidably mounted in the mechanical lock 6, the telescopic shaft 7 is controlled by the operation knob 8, a lower baffle 9 is fixedly mounted at one end of the telescopic shaft 7 far away from the mechanical lock 6, a cam 10 is fixedly mounted at a position of the energy storage shaft 3 below the mounting housing 2, when the mechanical lock 6 is in an unlocked state, the telescopic shaft 7 can be retracted into the mechanical lock 6, at this time, the lower baffle 9 cannot be in contact with the cam 10, when the mechanical lock 6 is in a locked state, the telescopic shaft 7 can extend out of the mechanical lock 6, the lower baffle 9 can be in contact with the cam 10, and the cam 10 cannot rotate, the energy storage shaft 3 will thus be locked against rotation.

In this embodiment, telescopic shaft 7 keeps away from the one end of mechanical lock 6 and still fixed mounting has an overhead gage 11, and overhead gage 11 is located the top of manually-operated axle 4, and when baffle 9 was locked the back with cam 10 down, overhead gage 11 will keep off the top at manually-operated axle 4, prevents that the staff from rotating energy storage shaft 3 through manually-operated axle 4 by force.
