[0044] See also Figure 1 This embodiment describes a window, which is a lifting and sliding door window, including a fan body 1, a frame body 2, a handle 3 and a lifting and pushing pulley mechanism 4. The lifting and pushing pulley mechanism 4 is arranged between the fan body 1 and the frame body 2 and is connected to the handle 3. When the fan body 1 is in the open state, the lifting and pushing pulley mechanism 4 lifts the fan body 1 and carries the fan body 1 to slide on the bottom edge of the frame body 2. When the fan body 1 reaches the locked position, the handle 3 drives the lifting and pushing pulley mechanism 4 to make the fan body 1 descend and lock on the frame body 2.

[0045] First embodiment

[0046] See also Figure 2-4 In the first embodiment, the lifting and pushing pulley mechanism 4 of the present scheme includes a lifting and pushing pulley transmission 10 and a lifting and pushing pulley 20, the lifting and pushing pulley 20 is provided with a bracket 60, the lifting and pushing pulley transmission 10 is connected to the bracket 60, one end of the bracket 60 is fixedly connected to the fan body 1 of the door and window, and the other end of the bracket can be lifted and connected to the lifting and pushing pulley 20, the lifting and pushing pulley transmission 10 is used to operate the lifting or lowering of the fan body 1; the lifting and pushing pulley 20 is connected to the lifting and pushing pulley transmission 10, and is used to carry the fan body 1 to slide on the bottom edge of the frame 2 of the door and window; wherein, the lifting and pushing pulley transmission 10, the lifting and pushing pulley 20 or the fan body 1 is provided with a first locking member 30, and the bottom edge of the frame 2 is provided with a second locking member 40 adapted to the first locking member 30, when the lifting and pushing pulley transmission 10 drives the fan body 1 to descend, the first locking member 30 and the second locking member 40 cooperate with each other to lock the fan body 1 on the frame 2.

[0047] It can be understood that the lifting and pushing transmission device 10 includes a lifting part 11, a rotating part 12 and a pushing and pulling part 13, the rotating part 12 is arranged between the lifting part 11 and the pushing and pulling part 13, the lifting part 11 is used to connect the driving mechanism, the pushing and pulling part 13 is used to connect the lifting and pushing pulley 20, and the rotating part 12 is hinged to the bracket 60. When the driving mechanism applies an up and down force to the lifting part, the rotating part 12 rotates, the pushing and pulling part 13 drives the lifting and pushing pulley 20 to slide horizontally, and the bracket 60 lifts or lowers the fan body 1.

[0048] The first locking member 30 of the present solution is arranged on the lifting part or the bracket 60 of the lifting and pushing transmission device 10. When the fan body 1 is lowered, the first locking member 30 and the second locking member 40 cooperate with each other to achieve the locking of the fan body 1 on the frame body 2. The first locking member 30 and the second locking member 40 in the present solution do not need to be arranged on the main transmission device. On the premise of not affecting the existing hardware structure, they can be supplementarily installed between the fan body 1 and the frame body 2. The processing and installation are convenient, and the fan body 1 can be stably locked on the frame body 2. The second locking member 40 in the present solution is not limited to being arranged at the closed position of the fan body 1, and can be arranged at any position of the bottom edge of the frame body 2, so as to achieve the stable locking of the fan body 1 at any position.

[0049] Furthermore, the lifting and pushing pulley mechanism 4 also includes a third locking member 50, which is arranged on the lifting and pushing pulley 20. When the fan body 1 is pushed and pulled to the closed position, the fan body 1 descends, and the first locking member 30 and the third locking member 50 respectively cooperate with the second locking member 40 to lock the fan body 1 on the frame 2.

[0050] Specifically, the first locking member 30 is a vertical locking pin 30A arranged along the sinking direction of the fan body 1, the third locking member 50 is a horizontal locking pin 50A arranged along the sliding direction of the fan body 1, and the second locking member 40 includes a vertical lock seat portion 41A and a horizontal lock seat portion 42A, the vertical lock seat portion 41A is opposite to the vertical locking pin 30A, and the horizontal lock seat portion 42A is opposite to the horizontal lock seat portion 42A.

The first rib 411A is preferably set perpendicular to the sliding direction (i.e., set at), and the second rib 421A is preferably set perpendicular to the lifting direction (i.e., set in the horizontal direction).

[0052] The vertical locking pin 30A and the horizontal locking pin 50A in this solution form a cross-direction pin locking structure. At this time, no matter how external force is used to lift the door leaf, the door leaf cannot be opened, that is, the purpose of locking is achieved.

[0053] The second locking member 40 in this solution can be configured to be slidably connected to the bottom edge of the frame 2, so that the fan body 1 and the frame 2 can be locked at any position.

[0054] Second embodiment

[0055] See also Figure 7-8 Different from the first embodiment, the second embodiment does not have the third locking member 50, and the structures of the first locking member 30 and the second locking member 40 are different.

[0056] Specifically, the first locking member 30 includes a rotary locking member 300B and a latch member 33B, the rotary locking member 300B includes a rotating connection portion 31B and a locking portion 32B, wherein the rotating connection portion 31B is connected to the rotating portion 12, and the latch member 33B is arranged on the lifting portion 11, when the fan body 1 is lifted or lowered, the rotating connection portion 31B and the rotating portion 12 rotate simultaneously, the locking portion 32B is provided with a hook, and the second locking member 40 is provided with a groove portion 41B adapted to the hook, when the fan body 1 is in the lifted state, the hook of the locking portion 32B rotates to be higher than the groove portion 41B, does not contact the groove portion 41B, and the fan body 1 is not locked; when the fan body 1 is lowered above the second locking member 40, the hook rotates and is stuck in the groove portion 41B to limit the lifting of the fan body 1, and the latch member 33B is further inserted into the second locking member 40 to limit the sliding of the fan body in the horizontal direction.

[0057] Third embodiment

[0058] See also Figure 9-11 , which is different from the first embodiment, the third locking member 50 of the third embodiment is a locking pin 50C, and the structures of the first locking member 30 and the second locking member 40 are different.

[0059] Specifically, the first locking member 30 is provided on the lifting part 11 or the bracket 60, and the first locking member 30 is provided with a plurality of first toothed members 31C toward the bottom side of the frame 2, and the second locking member 40 is provided with a plurality of second toothed members 41C toward the bottom side of the fan body 1. After the fan body 1 is lowered, the first toothed member 31C is engaged with the second toothed member 41C to limit the horizontal sliding of the fan body 1, and the locking latch 50C is located under the second locking member 4 to limit the lifting of the fan body. The cooperation of the first toothed member 31C, the second toothed member 41C and the locking latch 50C can lock the fan body 1 to the frame 2.

After the fan body 1 is lowered, the groove member 31D is inserted into the second locking member 40 and abuts against the protrusion member 41D to limit the sliding of the fan body. At this time, the limiting shaft 50D is inserted into the second locking member 40 to limit the lifting of the fan body, so as to lock the fan body 1 to the frame 2. Of course, this solution can also adopt the first locking member 30 with a protrusion member 41D and the second locking member 40 with a groove member 31D. As long as the two can limit the fan body 1, the fan body 1 can be locked on the frame 2.
