[0034] See also Figure 1 A door and window comprises a window frame 2 and a sash frame 3, wherein a lock 1 is arranged between the window frame 2 and the sash frame 3.

[0035] See also Figure 2-9 The lock 1 includes a lock base 10, a transmission housing 20 and a handle 30. The lock base 10 is provided with a first locking piece 11, and the lock base 10 is used to be installed on a first frame, which is a window frame 2 or a sash frame 3 of a door or window; the transmission housing 20 is provided with a transmission plate 21, and the transmission plate 21 is provided with a second locking piece 22 that cooperates with the first locking piece 11, and the transmission housing 20 is used to be installed on a second frame, which is a sash frame 3 or a window frame 2 of a door or window opened opposite to the first frame; the handle 30 is fixed to the second frame, and is used to rotate the transmission plate 21 to make the first locking piece 11 match the second locking piece 22, thereby locking the first frame and the second frame.

[0036] See also Figure 4 The handle 30 includes an operating handle 31, a handle mounting seat 32 and a handle transmission assembly 33. The operating handle 31 is used to apply a rotational force. The handle mounting seat 32 is provided on the second frame body. A handle receiving groove is provided in the handle mounting seat 32. The operating handle 31 can be opened and closed and connected to the handle mounting seat 32. The handle receiving groove is used to receive the closed operating handle 31. One end of the handle transmission assembly 33 can be rotatably connected to the operating handle 31, and the other end of the handle rotating assembly can be movably connected to the transmission housing 20. The operating handle 31 is used for the operator to apply a rotational force. The setting of the handle mounting seat 32 can store the operating handle 31 in the handle mounting seat 32 to ensure the aesthetics of the surface of the second frame body and facilitate the use of the operating handle 31.

[0037] The operating handle 31 rotates in a first direction to disengage the operating handle 31 from the handle mounting seat 32 ; the operating handle 31 rotates in a second direction to apply a force to the handle transmission assembly 33 to match the first locking member 11 with the second locking member 22 to lock the first frame and the second frame.

[0038] The lock 1 of this scheme can drive the transmission plate 21 on the transmission housing 20 by rotating the handle 30, so as to achieve the matching between the first locking member 11 and the second locking member 22, and realize the locking between the window frame 2 and the sash frame 3. When the operating handle 31 is in the handle mounting seat 32, the operating handle 31 is rotated in the first direction, and the operating handle 31 can be separated from the handle mounting seat 32. At this time, the operating handle 31 is rotated in the second direction. Since the rotating end of the operating handle 31 has been separated from the handle mounting seat 32, it will not be interfered by the handle mounting seat 32, which can not only realize the control of transmission locking, but also minimize the gap between the operating handle 31 and the handle mounting seat 32, so that the handle is more beautiful and easy to operate. Among them, the lock seat 10 is arranged on the window frame 2, the transmission housing 20 and the handle 30 are on the sash frame 3, and the handle 30 on the sash frame 3 can be rotated to achieve the locking between the window frame 2 and the sash frame 3. Of course, the lock seat 10 can also be arranged on the sash frame 3, and the transmission housing 20 and the handle 30 can be arranged on the window frame 2 to meet actual needs.

[0039] In this embodiment, the first locking member 11 is a locking rod, and the second locking member 22 is a locking groove, and the locking groove is used to insert and position the locking rod. The structures of the first locking member 11 and the second locking member 22 can also be swapped, as long as the same function can be achieved. In another embodiment, the first locking member 11 is a locking groove, and the second locking member 22 is a locking rod, and the locking groove is used to insert and position the locking rod.

[0040] See also Fig. 9 The lock rod includes a lock column 111 and a lock head 112 disposed at the protruding end of the lock column 111. The lock slot includes an insertion slot 221 and a locking slot 222 communicating with the insertion slot 221. The insertion slot 221 is used to insert the lock column 111 and the lock head 112. The locking slot 222 is used to insert the lock column 111 and limit the lock head 112. The handle 30 is used to drive the lock column 111 to move from the insertion slot 221 to the locking slot 222. It can be understood that the outer diameter of the lock head 112 is greater than the outer diameter of the lock column 111, the outer diameter of the insertion slot 221 is greater than the outer diameter of the locking slot 222, the outer diameter of the lock head 112 is greater than the outer diameter of the locking slot 222, and the outer diameter of the lock column 111 is smaller than the outer diameter of the locking slot 222. When the sash frame 3 and the window frame 2 are closed, the locking rod is automatically inserted into the locking groove. At this time, the locking column 111 is inserted into the insertion groove 221, and the locking head 112 is in the insertion groove 221. The transmission plate 21 slides, and the locking column 111 is passively moved down into the locking groove 222. At this time, the locking head 112 moves into the locking groove 222 and cannot extend out of the locking groove 222, thereby achieving locking between the first frame and the second frame.

[0041] See also Figure 8 The transmission housing 20 further includes an anti-misoperation assembly 23, which includes an anti-misoperation base 231, an anti-misoperation elastic member 232, and an anti-misoperation top column 233. The anti-misoperation base 231 is disposed in the lock slot; one end of the anti-misoperation elastic member 232 is connected to the anti-misoperation base 231; the anti-misoperation top column 233 is connected to the other end of the anti-misoperation elastic member 232 and can extend out of the insertion slot 221;

[0042] Before the lock rod is inserted into the lock slot, the anti-misoperation top column 233 is used to extend into the lock slot opening to make the lock slot opening surface flush with the frame surface it contacts; when the lock rod is inserted into the lock slot, the anti-misoperation top column 233 is pressed back into the lock slot member by the lock rod.

[0043] It should be noted that the provision of the anti-misoperation component 23 can protect the lock slot before the first frame and the second frame are closed, so as to prevent a groove from appearing on the surface of the second frame before the first frame and the second frame are closed. At the same time, since the anti-misoperation component 23 is retractable, it will not affect the insertion of the lock rod after the second frame is closed with the first frame.

[0044] Specifically, the operating handle 31 includes a handle bar 311, a handle rotating member 312 and a handle elastic member 313. The handle bar 311 includes a rotating end and a force-applying end. The handle rotating member 312 is disposed at the rotating end of the handle bar 311, and is used to pass through the handle mounting seat 32 and connect to the handle transmission assembly 33, wherein the width of the handle rotating member 312 is smaller than the width of the handle bar 311. The handle elastic member 313 is disposed between the handle bar 311 and the handle rotating member 312, and is used to apply a force to the handle bar 311, so that after the force-applying end of the handle bar 311 is separated from the handle receiving groove, the rotating end of the handle bar 311 can be separated from the handle receiving groove. The handle bar 311 and the handle rotating member 312 are connected through the handle elastic member 313, so that the handle bar 311 can pop out of the handle rotating member 312 after being pulled out of the handle receiving groove. It should be noted that in order to ensure the aesthetics as much as possible, the width of the handle rod 311 is basically the same as that of the handle storage slot. Since the width of the handle rotating member 312 is smaller than the width of the handle rod 311, when the handle rod 311 pops out, the rotating end of the handle rod 311 disengages from the handle storage slot, and the handle rotating member 312 can rotate freely in the handle storage slot without causing rotational interference, which can ensure that the handle rod 311 rotates smoothly while not affecting the aesthetics.

[0045] Specifically, the handle bar 311 is provided with a first sliding member 3111, and the handle rotating member 312 is provided with a second sliding member 3121. The first sliding member 3111 cooperates with the second sliding member 3121 to enable the handle bar 311 to be telescopically connected to the handle rotating member 312. The handle mounting seat 32 is also provided with a handle baffle 321 for limiting the force-applying end of the handle bar 311 from extending out of the handle receiving slot. The first sliding member 3111 and the second sliding member 3121 cooperate to achieve a telescopic connection between the handle bar 311 and the handle connecting member. The setting of the handle baffle 321 can play a certain limiting role on the force-applying end of the handle bar 311. Only when an external force is applied to the handle bar 311 in the direction of the rotating end, can the handle bar 311 be separated from the handle receiving slot.

[0046] In this embodiment, the first sliding member 3111 is a slide groove, and the second sliding member 3121 is a slide column; of course, in another embodiment, the first sliding member 3111 can be a slide column, and the second sliding member 3121 can be a slide groove. Both embodiments can achieve corresponding use effects.

[0047] See also Figure 5 The handle transmission assembly 33 includes a rotating transmission column 331 and a translation gear plate 332. The rotating transmission column 331 is inserted into the handle mounting seat 32. One end of the rotating transmission column 331 is rotatably connected to the operating handle 31 in the handle receiving groove. One end of the translation gear plate 332 is provided with a first rack 3321. The other end of the rotating transmission column 331 is provided with a second rack 3311 meshing with the first rack 3321.
