The working principle of the three-way window with the profile lock is as follows:

with the profile lock in half-empty, the second window 802 is in its initial state when it is pulled up to the position of the first window 801.

Windowing (locking): the user lifts the second window 802, the locking element moves with the second profile 600 towards the first profile 500, when the lower end of the snap-fit member 400 is in contact with the first limit stop 501, since the snap-fit member 400 is movable in the spring seat 203, when the second window 802 is further lifted up, the snap-fit member 400 and the snap member 300 are relatively displaced, the snap portion 308 of the snap member 300 is released from the snap groove 402, the right end of the clip 300 is pressed down by the force of the compression spring 102 in the locking cover 100, so that the button 301 end of the clip 300 is tilted up, meanwhile, the snap-fit members 400 are returned by the restoring force of the return spring 210, the button 301 is drilled out of the button-fit hole 101, the hook portions 302 of the snap-fit members 300 enter the fixing groove members 502 to hook the fixing groove members 502, and after the user releases his or her hand, the transverse hook portions 305 are dropped on the side edges of the fixing groove members 502, thereby allowing the entire lock and the weight of the second window 802 to rest on the fixed channel 502.

Close window (unlock): when a user needs to close the window, the user presses the button 301, the horizontal straight part 303 of the clamping piece 300 extrudes the clamping groove 402, the clamping groove 402 moves downwards and stretches the return spring 210, and after the clamping part 308 completely enters the clamping groove 402, the clamping groove 402 returns upwards under the action of the restoring force of the return spring 210 to hook a step formed by the horizontal straight part 303 and the button 301; meanwhile, the right end of the clip 300 presses the compression spring 102, so that the hook 302 of the clip 300 is separated from the fixing groove 502, and unlocking is completed.

Further, when the second window 802 moves down to the middle position, the latch 403 contacts the second limit stop 701 first, causing the latch 403 and snap-fit element 400 to displace relative to the spring seat 203, as the second window 802 further drops, the top end of the latch 403 contacts the whirl-stop plate 204, causing the whirl-stop plate 204 to rotate, and the rotating baffle 204 presses the clamping fitting piece 400, so that the clamping fitting piece 400 is separated from the horizontal straight part 303 of the clamping piece 300, the right end of the clip 300 is pressed down by the force of the compression spring 102 in the locking cover 100, so that the button 301 end of the clip 300 is tilted up, meanwhile, the clamping matching piece 400 returns under the restoring force of the return spring 210, the button 301 drills out of the button matching hole 101, the hook part 302 of the clamping piece 300 hooks the lower part of the third section bar 700, the lock bolt 403 is completely retracted into the clamping matching piece 400, and the lower end of the clamping matching piece 400 falls on the second limit baffle 701; at this time, the second window 802 cannot be lifted up because the hook 302 at the right end of the clip 300 hooks the lower part of the third profile 700, and cannot fall down because of the receiving function of the second limiting baffle.

Further, when unlocking is required, a user presses the button 301, the horizontal straight portion 303 of the clamping member 300 extrudes the clamping groove 402, the clamping groove 402 moves downwards and stretches the return spring 210, and after the clamping portion 308 completely enters the clamping groove 402, the clamping groove 402 returns upwards under the action of the restoring force of the return spring 210 to hook a step formed by the horizontal straight portion 303 and the button 301; meanwhile, the right end of the clamping member 300 extrudes the compression spring 102, so that the hook part 302 of the clamping member 300 is separated from the third section 700, and unlocking is completed.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
