Description

Technical Field

[0001] The present invention relates to the technical field of building hardware fittings, and particularly to an inward tilting and turning component with a locking mechanism. Background Art

[0002] When an ordinary inward tilting and turning window on the market is opened, it plays a role in ventilation with a gap, only replacing fresh air in the room, but does not achieve safety performance. Under normal use conditions, when the window sash is in the inward tilting and turning state and there is a negative wind pressure in the room, the window sash in the inward tilting and turning state may be blown to the closed state at this time. When the negative wind pressure decreases, the window sash automatically opens to the inward tilting and turning state again. Repeating this way may cause the hardware to be damaged and ineffective, and the window sash to be damaged, and in severe cases, it may even endanger personal safety. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an inward tilting and turning component with a locking mechanism and a stable structure.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: an inward tilting and turning component with a locking mechanism, including a clamping point component arranged on a first window component, a first connecting seat fixedly connected to the first window component, a second connecting seat fixedly connected to a second window component, a first support rod connected between the first connecting seat and the second connecting seat, and a second support rod simultaneously connecting the first support rod and the first connecting seat; wherein the first window component and the second window component are respectively a window sash or a window frame; the clamping point component includes a movable pull rod that is adjusted along the length direction and a clamping point arranged on the movable pull rod; a sliding groove extending in the same direction as the length direction of the movable pull rod is opened on the first connecting seat, a rotating shaft that is slidably fitted in the sliding groove is arranged at one end of the first support rod, and the other end of the first support rod is pivotally connected to the second connecting seat; both ends of the second support rod are pivotally connected to the first support rod and the first connecting seat respectively, and a first card slot and a second card slot for cooperating with the clamping point are reserved on the second support rod. When the window sash is in the closed state, the clamping point is in the first card slot, and when the window sash is opened to the maximum opening degree, the clamping point is in the second card slot.

[0005] The beneficial effect of the present invention is: the inward tilting and turning component with a locking mechanism of the present invention can use the cooperation between the clamping point and the first card slot and the second card slot to lock the window sash. Specifically, when the window sash is closed, its clamping point is in the first card slot, and the cooperation between the first card slot and the clamping point can be used to lock the window sash in the closed state to prevent the window sash from being naturally opened by the wind. Similarly, when the window sash is opened, the second support rod is driven to make the clamping point slide into the second card slot, thereby locking the window sash in the open state to prevent the window sash from closing naturally. When unlocking is required, the movable pull rod can be operated through the handle to drive the clamping point to leave the first card slot or the second card slot, and the usage method is simple.

[0006] Preferably, it further includes a rod driving mechanism arranged on the first window component for driving the movable rod. The rod driving mechanism includes a linkage rod, a connecting component connecting the linkage rod and the movable rod, a rack arranged on the linkage rod, a gear meshing with the rack, and a handle coaxially connected with the gear. By rotating the handle, the gear is driven to rotate, and finally the movable rod is driven through the transmission of the rack, so as to adjust the clamping point to achieve unlocking or locking.

[0007] Preferably, the connecting component includes an angle member, a first connecting piece, and a second connecting piece. The two ends of the first connecting piece are respectively connected to the angle member and the movable rod, the two ends of the second connecting piece are respectively connected to the angle member and the linkage rod, and the angle member is made of a soft material for pulling the first connecting piece and the second connecting piece. The angle member can be used to realize the angular arrangement of the movable rod and the linkage rod, making full use of the space of the window sash or window frame.

[0008] Preferably, the first card slot is in an L-shaped structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0017] The technical solution claimed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] SeeFigures 1 to 7 As shown, an inner bottom-hung component with a locking mechanism in this embodiment includes a clamping point component disposed on the first window component 6, a first connecting seat 2 fixedly connected to the first window component 6, a second connecting seat 3 fixedly connected to the second window component 7, a first support rod 41 connected between the first connecting seat 2 and the second connecting seat 3, and a second support rod 42 connecting the first support rod 41 and the first connecting seat 2 at the same time.

[0019] In this embodiment, the first window component 6 is a window sash, and the second window component 7 is a window frame respectively. In other embodiments, the two can be interchanged according to actual situations.

[0020] The clamping point component includes a movable pull rod 11 that is adjusted movably along the length direction and a clamping point 12 disposed on the movable pull rod 11. In this embodiment, a pull rod driving mechanism for driving the movable pull rod 11 is further disposed on the first window component 6. The pull rod driving mechanism includes a linkage rod 51, a connecting component connecting the linkage rod 51 and the movable pull rod 11, a rack disposed on the linkage rod 51, a gear meshing with the rack, and a handle 653 coaxially connected to the gear. The connecting component includes a corner piece 521, a first connecting piece 522, and a second connecting piece 523. Two ends of the first connecting piece 522 are respectively connected to the corner piece 521 and the movable pull rod 11, two ends of the second connecting piece 523 are respectively connected to the corner piece 521 and the linkage rod 51, and the corner piece 521 is made of a soft material for pulling the first connecting piece 522 and the second connecting piece 523. The corner piece 521 can be used to realize the angular arrangement of the movable pull rod 11 and the linkage rod 51 to make full use of the space of the window sash or the window frame. By rotating the handle 653 to drive the gear to rotate, and finally driving the movable pull rod 11 through the transmission of the rack, the clamping point 12 is adjusted to achieve unlocking or locking.

[0021] A chute 21 extending in the same direction as the length direction of the movable pull rod 11 is formed on the first connecting seat 2. One end of the first support rod 41 is provided with a rotating shaft that is slidably fitted in the chute 21, and the other end of the first support rod 41 is pivotally connected to the second connecting seat 3 at the same time. Two ends of the second support rod 42 are respectively pivotally connected to the first support rod 41 and the first connecting seat 2, and a first card slot 421 and a second card slot 422 for cooperating with the clamping point 12 are reserved on the second support rod 42, wherein the first card slot 421 is in an L-shaped structure. When the window sash is in the closed state, the clamping point 12 is in the first card slot 421, and when the window sash is opened to the maximum opening degree, the clamping point 12 is in the second card slot 422.

[0022] The usage method in this embodiment is as follows:

[0023] When the window sash is closed, the clamping point 12 is located within the first card slot 421. At this time, the window sash cannot be naturally opened, preventing the window sash from being naturally opened by the wind.

[0024] When the window sash needs to be opened, the operating handle 653 is operated to drive the clamping point 12 to move within the first card slot 421 and move to the exit of the first card slot 421. At this time, the first card slot 421 no longer cooperates with the clamping point 12 for locking, and the window sash can be freely opened.

[0025] After the window sash is opened, the operating handle 653 is operated to move the clamping point 12 reversely to its original position. At this time, the clamping point 12 slides into the second card slot 422 and cooperates with it for locking. The window sash cannot be freely closed and remains at the current opening degree.

[0026] When the window sash needs to be closed again, the operating handle 653 is operated again to make the clamping point 12 leave the second card slot 422, and the locking between the two is released. The window sash can be freely closed.

[0027] Specifically, when the window sash is closed, its clamping point 12 is located within the first card slot 421. The cooperation and locking between the first card slot 421 and the clamping point 12 can lock the window sash in the closed state, preventing the window sash from being naturally opened by the wind. Similarly, when the window sash is opened, its second support rod is driven to make the clamping point 12 slide into the second card slot 422, thereby locking the window sash in the open state and preventing the window sash from being naturally closed. When unlocking is required, the movable pull rod 11 can be operated through the handle 653 to drive the clamping point 12 to leave the first card slot 421 or the second card slot 422, and the usage method is simple.

[0028] The above-described embodiments are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Any person skilled in the art can make more possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. Therefore, all equivalent changes made according to the idea of the present invention without departing from the content of the technical solution of the present invention should be covered within the protection scope of the present invention.
