working principle:

Insert the key 7 into the lock core 305, turn the key 7, and the key 7 will drive the lock core 305 to move the elastic telescopic block 307, that is, the reset block of the first limit block 311 and the second limit block 312 is pushed by the dial block 3051 3113, the first limiting block 311 and the second limiting block 312 are moved towards each other; at this time, the holders 3112 of the first limiting block 311 and the second limiting block 312 are respectively retracted inwardly and then separated from the second fixed limit The hole 212 is fixed. At the same time, the rotating handle 301 is pushed out of the surface of the fixed sleeve 101 under the action of the ejector spring 308; at this time, the lock tongue 201 can be controlled by rotating the rotating handle 301. The control process is as follows: , The lock tongue 201 and the rotating handle 301 are both in a horizontal state. When the rotating handle 301 is rotated to a position at a 90 degree angle to the horizontal, the lock tongue 201 is also at a 90 degree angle position and restricts the door panel. At this time, the inside of the door and window lock The positioning pin 205 rotates 90 degrees, and the rotation path is the bottom horizontal groove position of the "L"-shaped groove formed by the adjusting sleeve 204 and the housing 1.

Further, the rotating handle 301 is rotated to a position at an angle of 180 degrees from the initial state. During this process, the internal positioning pin 205 will be pushed by the protrusion inside the housing 1 and enter the limiting slot 210 and be limited by the limiting slot 210.

When the adjustment of the lock tongue 201 is completed and the rotating handle 301 needs to be hidden, just press the top of the rotating handle 301, and the handle assembly 3 will move downward under the positioning of the positioning protrusion 309 and the positioning groove 310 until the first limit is reached. The retaining block 3112 of the positioning block 311 and the second limiting block 312 reaches the second fixed limiting hole 212, and the retaining block 3112 loses the resistance of the inner wall of the handle cavity 208 and then extends outward under the action of the return spring 313. At this time, due to the pushing of the reset oblique block 3113 of the first limit block 311 and the second limit block 312, the shift block 3051 will also drive the lock cylinder 305 to rotate to the initial position.

The door and window lock provided by the embodiment of the present disclosure can realize the hiding of the rotating handle 301 through the cooperation of the rotating handle 301 and the hidden part 302. When the door needs to be opened, the rotating handle 301 can be unlocked by rotating the lock core 305 and the hidden part 302, so that the rotating handle Part 301 pops out of the housing 1 for the user to hold; when the door does not need to be opened, the rotating handle 301 can be pressed into the housing 1 to hide, which improves the existing door lock handle because it cannot be hidden, and protruding outside may cause the handle to be easily damaged or cause safety hazards, etc. problem. The open door and window lock with the concealable handle skillfully utilizes the characteristics of each structure, the overall structure is compact, the adjustment is effective and convenient, and it is suitable for popularization and application in various places.

The second embodiment:

1 to 3, an embodiment of the present disclosure provides a door and window lock with a concealable handle, which includes a housing 1, a latch assembly 2 and a handle assembly 3. The latch assembly 2 includes an adjusting barrel 203, and the adjusting barrel 203 is opened There is a positioning groove 310 extending in the axial direction. The end of the adjusting cylinder 203 extends out of the housing 1 and is fixed to the lock tongue 201; the handle assembly 3 includes a rotating handle 301 and an elastic telescopic block 307. The rotating handle 301 is provided with a positioning protrusion 309 for positioning The protrusion 309 is slidably engaged with the positioning groove 310, so that the rotating handle 301 can move axially relative to the adjusting barrel 203 without being able to rotate in the circumferential direction. The elastic telescopic block 307 is provided on the rotating handle 301 and configured to lock the rotating handle 301 and the adjusting barrel 203 The relative position in the axial direction, so that the rotating handle 301 is kept in the housing 1 or is configured to unlock the relative position of the rotating handle 301 and the adjusting barrel 203 in the axial direction, so that the rotating handle 301 can be relative to the adjusting barrel 203 axis Move to extend the housing 1.

The working principle and technical effects obtained by the door and window lock provided in this embodiment are basically the same as those in the first embodiment, and will not be repeated here.
