[0034] See also Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a door and window structure with a secondary locking function provided by an embodiment of the present invention; Figure 2 This is a structural diagram of a two-stage locking mechanism provided in one embodiment of the present utility model.

[0035] To address the aforementioned technical issue of the unstable locking mechanism of conventional door and window structures, or to achieve at least one of the aforementioned advantages or other advantages, one embodiment of the present invention provides a door and window structure with a two-stage locking function. As shown in the figure, the door and window structure with a two-stage locking function includes a first frame 10, a second frame 20, and a two-stage locking mechanism.

[0036] The second frame 20 is movably connected to the second frame 10. In a specific implementation, the first frame 20 and the second frame 20 can be made of metal, such as aluminum alloy or other metal materials with good plasticity, strength and aesthetics.

[0037] The secondary locking mechanism 30 is disposed on the second frame 20 and is movably connected to the first frame 10. When the secondary locking mechanism 30 is unlocked, it is not in contact with the first frame 10, allowing the second frame 20 to be pushed or pulled relative to the first frame 10. When the secondary locking mechanism 30 is locked, it is in contact with the first frame 10, preventing the second frame 20 from moving relative to the first frame 10.

[0038] Please combine Figure 2 See Figure 3 The secondary locking mechanism 30 includes a housing 31, a first button 32, a second button 33, and a third button 34. The housing 31 is provided with corresponding holes, and the first button 32, the second button 33, and the third button 34 are respectively disposed in different holes on the housing 31 and are movably connected to the housing 31.

[0039] When implementing it specifically, Figure 3 As shown, the first button 32 is movably connected to the second button 33, and the second button 33 can limit the movement of the first button 31. That is, when the first button 32 is pressed, the second button 33 pops up, which can prevent the first button 32 from popping up, thereby keeping the first button 32 locked with the first frame 10. When the second button 33 is pressed, the first button 32 is released, and the first button 32 pops up, unlocking the state.

[0040] Based on the above, the third button 34 is a push button. The third button 34 is movably connected to the second button 33 and can restrict the movement of the second button 33. That is, when the first button 32 is pressed, the second button 33 pops up, preventing the first button 32 from popping up, thereby keeping the first button 32 locked with the first frame 10. At this time, pushing the third button 34 toward the second button 33 causes the third button 34 to contact the second button 33, causing the second button 33 to be locked by the third button 34 and unable to be pressed, forming a secondary lock. This prevents the second button 33 from being accidentally pressed and releasing the first button 32, thereby improving safety.

[0041] In some preferred embodiments, the first button 32 and the second button 33 are respectively disposed on two perpendicular surfaces of the housing 31. The third button 34 is coplanar with the second button 33, so as to form a linkage locking relationship among the first button 32, the second button 33, and the third button 34.

[0042] Furthermore, please combine Figure 3 See Figure 4 The first button 32 comprises a first button cap 321, a pin 322, and a first spring 323. In practice, the first button cap 321 is slidably coupled to the housing 31, allowing the first button 32 to be pressed and released from the housing 31. A sliding portion 324 is provided on the first button cap 321. The sliding portion 324 slidably couples with the second button 33, thereby creating a linkage between the first and second buttons 32 and 33.

[0043] One end of the pin 322 is connected to the first button cap 321, while the other end of the pin 322 extends through the second frame 20 and is movably connected to the first frame 10. When the first button 32 is pressed, the pin 322 engages and locks with the first frame 10, forming a locked state. It is understood that a snap-fitting slot or hole can be provided on the first frame 10 at the position corresponding to the pin 322 (conventional solution, not shown in the figure), which will not be further described here.

[0044] The first spring 323 is sleeved on the pin shaft 322, one end of the first spring 323 abuts against the first button cap 321, and the other end abuts against the second frame 20. The first spring 323 can provide a reset force for the first button 32. After the second button 33 is pressed to release the first button 32, the first button 32 can bounce upward to release the locked state.

[0045] Please combine Figure 3 See Figure 5 The second button 33 includes a second button cap 331 and a second spring 332. The second button cap 331 is slidably connected to the housing 31, allowing the second button 33 to be pressed and released from the housing. A stepped groove 333 is provided on the side of the second button cap 331 facing the first button 32. The stepped groove 333 is slidably connected to the sliding portion 324. The second spring 332 is arranged along the sliding direction of the second button 33, with one end of the second spring 332 abutting the second button cap 331 and the other end abutting the second frame 20.

[0046] In specific implementation, when the first button 32 is pressed, the sliding portion 324 slides along the stepped groove 333. When the sliding portion 324 reaches the stepped portion of the stepped groove 333, the second button cap 331 is pressed upward by the second spring 332, which then engages the sliding portion 324 through the stepped groove 333, preventing the first button 32 from bouncing upward, thereby locking the first button 32. When the second button 33 is pressed, the sliding portion 324 disengages from the stepped portion of the stepped groove 333. Under the pressure of the first spring 323, the first button 32 bounces upward, releasing the locked state.

[0047] Please combine Figure 3 See Figure 6 The third button 34 includes a third button cap 341. The third button cap 341 is slidably connected to the housing 31, allowing the third button 34 to move relative to the housing 31 toward the second button 33. A stopper 342 is provided on the side of the third button cap 341 facing the second button 33. The stopper 342 is movably connected to the second button cap 331.

[0048] In practice, when the first button 32 is pressed, the second button 33 is pushed upward by the second spring 332, causing the pin 322 to contact the first frame 10, forming a locked state. At this point, a gap exists between the second button cap 331 and the housing 31. Pushing the third button cap 341 toward the second button 33 causes the stopper 342 to extend into the gap between the second button cap 331 and the housing 31, limiting the position of the second button cap 331 and forming a two-stage linkage lock, preventing the first button 32 from being released after the second button 33 is pressed.

[0049] Preferably, if Figure 7 As shown, after the second button 33 bounces upward, the width W of the gap between the second button cap 331 and the housing 31 is slightly larger than the thickness H of the limiting portion 342 .

[0050] On the basis of the above, a sliding stop portion 343 is provided on the side of the third button cap 341 away from the second button 33. A sliding stop groove 311 is provided on the housing 31 at a position corresponding to the sliding stop portion 343. The sliding stop portion 343 and the sliding stop groove 311 are slidably connected. Figure 8 As shown, there are two pairs of sliding grooves 311. The two pairs of sliding grooves 311 are arranged along the movement direction of the third button 34. When the third button 34 is pushed, the sliding portion 343 can move between the two pairs of sliding grooves 311, limiting the third button 34 and preventing the second-stage locking state from being invalid due to displacement of the third button 34 after the second-stage locking state is established.

[0051] In some preferred embodiments, the sliding portion 343 includes a first end 3431 and a second end 3432. A third spring 344 is disposed between the first end 3431 and the second end 3432. The third spring 344 provides pressure to tightly connect the first end 3431 and the second end 3432 to the corresponding sliding groove 311, thereby ensuring the stability of the third button 34.

[0052] In some preferred embodiments, the door and window structure with a secondary locking function further includes a guardrail 40. The guardrail 40 is provided on the first frame 10, which can further eliminate potential safety hazards.

[0053] In some other embodiments, such as Figure 9 As shown, the door and window structure with a secondary locking function can be a three-opening structure.

[0054] In some preferred embodiments, Figure 10 As shown, the sliding opening and closing direction of the door and window structure with a secondary locking function is longitudinal.

[0055] Furthermore, first magnetic members 50 are provided at the left and right ends of the second frame 20. First magnetic members 50 (not shown) are also provided at positions corresponding to the first magnetic members 50 on the first frame. When the window sash is opened, the corresponding first magnetic members 50 attract each other, preventing the window sash from sliding and improving safety.

[0056] In some preferred embodiments, a second magnetic member (not shown) is provided on a side of the second frame body 20 away from the secondary locking mechanism 30 to increase the magnetic attraction between the second frame body 20 and the first frame body 10 and further improve safety.

[0057] To sum up, compared with the existing technology, the door and window structure with a two-level locking function provided by the utility model realizes that the first button, the second button and the third button can be locked in a linked manner by designing the locking structure as a two-level locking mechanism, which can greatly reduce the situation where children mistakenly operate the locking structure and cause the window sash to be unlocked and moved, thereby improving safety and eliminating safety hazards.
