[0021] like Figure 1-Figure 4As shown, the front handle assembly is composed of a blade lock core 1, a lock core sleeve 2, a small washer 3, a front handle body 4 and a front handle core 5, and the front handle washer 6, a front baffle cover 7, a switch indicator sheet 8, a safety bead 9, a first clutch 10, a square spring 11, a safety rod 12, a front baffle 13, a rotation spring 14, a set screw 15, a first screw 16, a front rotating frame 17, a front baffle stud 18, a retaining spring 19 and a square body 20. In actual use, by rotating the blade lock core 1 90 degrees counterclockwise, the switch indicator sheet 8 can be moved leftward and the safety bead 9 can be propped open through the action of the lock core sleeve 2, the linkage safety rod 12 and the first clutch 10, so that the safety bead 9 is stuck in the groove of the front baffle 13, thereby making the front handle The body 4 and the front baffle 13 cannot be twisted, forming a locked state. As the switch indicator piece 8 moves to the left, the specific text and color of the switch indicator piece 8 are displayed in the fan-shaped window on the front cover 7, which serves to prompt the locked state. The blade lock core 1 is rotated 90 degrees clockwise. Through the effects of the lock core sleeve 2, the linkage safety rod 12 and the first clutch 10, the switch indicator piece 8 can be moved to the right and the safety bead 9 can be retracted, so that the safety bead 9 is embedded in the front handle core 5, so that the front handle body 4 and the front baffle 13 can freely move up and down 45 degrees, forming an open state. As the switch indicator piece 8 moves to the right, the specific text and color of the switch indicator piece 8 are displayed in the fan-shaped window on the front cover 7, which serves to prompt the open state.

[0022] The anti-lock clutch body 28 is connected to the anti-lock clutch fixing plate 26 in a sliding manner, and the anti-lock clutch body 28 is connected to the rear baffle 29 in a snap-fitting manner, and an anti-lock clutch compression spring 27 is also connected between the anti-lock clutch body 28 and the rear baffle 29; the knob assembly 32 is connected to the safety rod 12, and the outer protrusion of the knob assembly 32 and the arc groove on the button cover 22 are connected in a sliding manner; one end of the safety button compression spring 31 is fixed in the knob assembly 32, and the other end of the safety button compression spring 31 is fixed to the square body 20;

[0023] like Figure 1-Figure 4As shown, a rear handle assembly is assembled by the rear rotating frame 21, the button cover 22, the second screw 23, the third screw 24, the fixing plate 25, the anti-lock clutch fixing plate 26, the anti-lock clutch compression spring 27, the anti-lock clutch body 28, the rear baffle 29, the cross countersunk screw 30, the safety button compression spring 31, the knob assembly 32 and the rear handle 33 to form a rear handle assembly, the anti-lock clutch body 28, the anti-lock clutch compression spring 27 and the anti-lock clutch fixing plate 26 are installed on the rear baffle 29 through the third screw 24, and then the rear handle assembly is assembled. The second screw 23 and the fixing plate 25 are installed on the rear baffle 29 to form a complete rear baffle assembly. The rear baffle assembly adopts a newly developed button-type (left-opening and right-opening) indiscriminate installation new structure. Pressing and lifting the rear handle 33 can quickly open the door to achieve a quick escape function. For the disabled, they only need to use a simple pressing knob assembly 32 to complete the locking function. Simply lifting or pressing the rear handle 33 forty-five degrees can complete the opening function of the lock, and the door can be quickly opened to achieve a quick escape function.

[0024] The newly developed rear-end quick opening and closing mechanism can rotate the knob assembly 32 90 degrees by pressing the knob assembly 32 and coordinating the sliding action between the pressing knob assembly 32 protrusion and the arc groove on the button sleeve 22. The knob assembly 32 slides down to the bottom, and the anti-lock clutch body 28 acts to lock the knob assembly 32, forming a closing action. Because the button sleeve 22 drives the safety rod 12, the first clutch 10 and the safety bead 9 to work together, it is in a locked state. When we need to open or escape quickly, we only need to simply lift or press down the rear handle 33 of the rear end component 45 degrees, and push the anti-lock clutch body 28, separate the knob assembly 32, the safety button compression spring 31, and push the knob assembly 32 to bounce up through the slot of the rear handle 33. The button sleeve 22 rotates 90 degrees to link the safety rod 12, the first clutch 10 and the safety bead 9, which is the opening state.

[0025] In summary, the convenient switch indicates the escape function lock. When in use, first install the front handle body 4 front block component to the outside of the door, with a lock tongue 34 in the middle. Similarly, install the rear handle 33 rear block component to the inside of the door. The middle is fixed by the square body 20, the front block stud 18, the set screw 15, the lock tongue 34, and the front and rear block components are fixed by the cross countersunk screws 30. The size of the front block cover 7 is consistent with that of the rear baffle 29. Its structure is relatively firm, and its performance is more stable and its surface treatment is more diverse. The middle square body 20 is connected to the rear rotating frame 21 through the lock tongue 34, which makes the equipment stronger and more durable during use. The front handle body 4 is connected to the front rotating frame 17 and the rear The handle 33 cooperates with the rear rotating frame 21. The front rotating frame 17 and the rear rotating frame 21 are formed in one step using 1.5MM thick cold-rolled steel. After subsequent carburizing treatment, they have stronger pressure resistance and are more durable during use. Through the blade lock core 1, it can be set to limited time use or open use during use. In addition, the fan-shaped window on the front door cover 7 and the specific text color display of the switch indicator piece 8 make it clear at a glance. Since the fan-shaped marking window is located at the upper end of the front door cover 7, it can well avoid accidental opening. At the same time, the door lock with indication quick escape function can be installed on a left-opening door or a right-opening door, and can be opened left and right, which is easy to install. This is the working principle of the convenient escape lock with indication function.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
