Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
See Fig. 1 and Fig. 2, locking device of the present invention by access patch 1 rotate latching device and the safety block with safety block positioning seat that is arranged in fixed plate matches and collectively forms.
Rotate latching device and include shaft seat 102, back-up ring A 103, back-up ring B104, rotating shaft 105, self-locking nut 106, bumper bar 107.
Shaft seat 102 is fixed on the upper of access patch 1 through countersunk head screw 101,
Being equipped with rotating shaft 105 in shaft seat 102, rotating shaft 105 is welded with pin, back-up ring 104 is between pin and access patch 1, and back-up ring 104 and pin are provided commonly for countershaft 105 and carry out spacing,.
