Detailed Description
The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.
Example 1
An overhaul cabin door lock of a special vehicle comprises a lock shell 1, a lock rod 2, a lock tongue 3 and a lock spring 4;
a lock spring 4 is arranged between the lock shell 1 and the lock tongue 3, a lock rod 2 is arranged in the middle of the lock shell 1 in a penetrating way, and the lock rod 2 is in sliding connection with the lock tongue 3 through threads; the lock shell 1 is welded with the overhaul cabin door, and an irregular limiting notch is arranged on the lock shell 1 and used for positioning during installation. The bolt 4 is used for guaranteeing that the bolt 3 does not deflect in a vibrating state.
One end of the lock tongue 3 is provided with an adjusting screw 5 for limiting the travel of the lock tongue 3 on the lock rod 2, and the travel range of the lock tongue 3 on the lock rod 2 can be adjusted by controlling the adjusting screw 5;
one side of the lock tongue 3 is provided with a limit rod 6, and one end of the limit rod 6 is welded with the lock shell 1. The limiting rod 6 is used for limiting the deflection angle of the lock tongue 3, so that the lock tongue 3 can deflect within the range of 90 degrees, and the opening and closing states of the maintenance cabin door lock are controlled.
One end of the lock rod 2 is provided with a polygonal lock head 8, and the other end of the lock rod 2 is provided with a limiting pin 9. The special spanner can drive the lock tongue 3 to deflect along the movement direction of the lock rod 2 by controlling and operating the lock rod 2 through the polygonal lock head 8.
When locking is needed, a specific wrench is operated to rotate the polygonal lock head 8 according to the locking direction, the lock tongue 3 is driven to deflect according to the locking direction, one side of the lock tongue 3 is provided with a limiting rod 6, the limiting rod 6 limits the front end position of the lock tongue 3, the deflection angle of the lock tongue 3 reaches the optimal locking position, and as the lock rod 2 continues to rotate, the lock tongue 3 keeps the current locking position to move along the axis direction of the lock rod 2, and is matched with the structure of the overhaul cabin door to be locked until one end of the adjusting screw 5 is abutted with the lock shell 1;
when the lock needs to be opened, the special spanner is operated to rotate the polygonal lock head 8 according to the opening direction, the lock rod 2 rotates to drive the lock tongue 3 to move along the axis direction of the lock rod 2 until the lock tongue 3 is separated from the structural limitation of the overhaul door and deflects according to the opening direction, the limit rod 6 limits the rear end position of the lock tongue 3, the deflection angle of the lock tongue 3 reaches the optimal opening position, the interference of the lock tongue 3 on the opening of the overhaul door is avoided, and the lock spring 4 is used for guaranteeing that the lock tongue 3 cannot deflect and move under the vibration state.
A sealing ring 7 is arranged between the lock shell 1 and the lock rod 2, so that the waterproof property and the sealing property of the structure are ensured; a dust cover 10 is arranged between the lock spring 4 and the lock shell 1, and dust is placed in the lock shell 1 to interfere with the structure operation.
One side of the adjusting screw 5 is provided with a locking screw 11 to prevent the lock tongue 3 from excessively moving to be separated from the lock rod 2.
