Technical Field

[0001] This utility model relates to the technical field of top-hung window locking devices, specifically, to a device that locks a top-hung window simultaneously after it closes in strong winds. Background Technology

[0002] Top-hung windows are often kept open for ventilation, but in the event of a sudden strong wind, they are prone to damage or safety hazards if not closed in time. In existing top-hung window technology, strong winds can easily force them shut or even blow them open, posing safety risks and potentially causing damage. Current top-hung windows typically lack effective automatic closing and locking mechanisms in strong winds. Some automatic closing and locking devices rely on electronic sensors and motors, which are costly, structurally complex, and dependent on power supplies, failing to effectively cope with strong winds and other severe weather conditions, causing inconvenience and safety risks for users. This invention proposes a purely mechanical solution that achieves rapid closing and locking, preventing the windows from being blown open by the wind once locked. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device that locks a top-hung window when it is closed by strong wind. The device consists of a transmission and reset structure composed of components such as a slide rail, a slider, a lever, a paddle, and a spring. When the window is closed by strong wind, it can automatically drive the moving rod to move. The slider slides in the slide rail and drives the lever. The spring force makes the paddle have a reset tendency, and finally realizes the automatic locking of the window after it is closed, effectively preventing strong wind from blowing the window open.

[0004] A device for locking a top-hung window after it closes in strong winds includes a bottom frame of the top-hung window. The bottom frame is connected to a transmission rod assembly. The transmission rod assembly includes a moving rod, a slide rail, a slider, a lever, a lever shaft, a stop block, and a spring. The moving rod is installed in a standard slot in the bottom frame of the top-hung window. The slide rail is fixedly mounted on the lower side of the moving rod. An L-shaped slot is provided on one side of the slide rail, connecting the lower and upper sides. A slider is slidably mounted within the slide rail. A lever is mounted within a track on the slider. A lever is fixedly mounted on one side of the lever. A lever receiving cavity is provided on one side of the slider, through which the lever passes. The lever receiving cavity corresponds to the slot and is L-shaped. One end of the lever is fixedly connected to the spring, and the other end of the spring is fixedly connected to the stop block, which is fixed to one end of the slide rail.

[0005] As a further limitation of this technical solution, it also includes a lock seat, which is fixed to the bottom of the window frame. A symmetrically arranged limiting strip is fixed to the upper middle part of the lock seat, and the symmetrical limiting strip forms a track groove. A locking point is slidably arranged in the track groove. The locking point is an L-shaped block with symmetrical slots. The locking point and the lock seat are connected by bolts. The lower side of the locking point is serrated, and the bottom of the track groove is a serrated groove that fits the lower side of the locking point.

[0006] As a further limitation of this technical solution, a stop is fixedly provided at both ends of one side of the lock seat, the stop is provided corresponding to the lever, and the lever can abut against the side wall of the stop corresponding to the moving rod.

[0007] As a further limitation of this technical solution, the paddle is arc-shaped.

[0008] As a further limitation of this technical solution, the side of the stop away from the paddle is an arc surface or a downwardly sloping surface.

[0009] As a further limitation of this technical solution, the stop edge is L-shaped and the stop edges at both ends are symmetrically arranged.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are:

[0011] (1) The transmission and reset structure, which consists of components such as slide rail, slider, lever, paddle, and spring, can automatically drive the moving rod when the window sash is closed by strong wind. The slider slides in the slide rail and then drives the lever. The elastic force of the spring makes the paddle have a reset tendency, and finally realizes automatic locking after the window sash is closed, effectively preventing strong wind from blowing the window sash open.

[0012] (2) The locking point adopts an adjustable design. The limiting strip of the lock seat forms a track groove, which is matched with the sliding adjustable L-shaped locking point. The locking point is connected by bolts and the sawtooth design of the lower side of the locking point and the bottom of the track groove can adapt to the differences in the closing position of different window sashes, ensuring that the lever can be accurately locked into the locking point, and enhancing the applicability of the device to different specifications of top-hung windows.

[0013] (3) The arc-shaped paddle reduces stress concentration when in contact with the guard edge, making the contact smoother and reducing the probability of jamming or failure to lock accurately; the arc surface or downward inclined surface of the guard edge away from the paddle plays a guiding role, making it easier for the paddle to slide into the mating area to lock.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] A device for locking a top-hung window after it closes in strong winds includes a bottom frame 1 of the top-hung window. The bottom frame 1 is connected to a transmission rod assembly 2. The transmission rod assembly 2 includes a moving rod 205, a slide rail 201, a slider 202, a lever 2022, a lever 2022 shaft, a stop block 203, and a spring 204. The moving rod 205 is installed in a standard slot in the bottom frame 1. The slide rail 201 is fixedly mounted on the lower side of the moving rod 205. A slot 2011, L-shaped, is provided on one side of the slide rail 201 at the connection between one side and the lower side of the slide rail 201. A slider 202 is slidably disposed within the slide rail 201. A lever 2022 is disposed within a slide rail on the slider 202. A lever 2021 is fixedly disposed on one side of the lever 2022. A lever receiving cavity 2023 is provided on one side of the slider 202. The lever 2021 passes through the lever receiving cavity 2023. The lever receiving cavity 2023 is disposed corresponding to the slot 2011. The lever receiving cavity 2023 is L-shaped. One end of the lever 2022 is fixedly connected to the spring 204. The other end of the spring 204 is fixedly connected to the block 203. The block 203 is fixed to one end of the slide rail 201.

[0023] In this embodiment, by installing the movable rod 205 in the standard slot of the bottom frame 1 of the upper-hung window, the slide rail 201, slider 202, lever 2022, paddle 2021, spring 204 and other components cooperate to form a transmission and reset structure. The movable rod 205 provides a mounting base for other components. The cooperation between the slide rail 201 and the slider 202 enables horizontal sliding. The slot 2011 and L... The shaped lever receiving cavity 2023 guides the lever 2021 to move along a specific trajectory. When the window sash is closed by strong wind, it drives the moving rod 205 to move. The slider 202 slides in the slide rail 201, which in turn drives the lever 2022. The elastic force of the spring 204 makes the lever 2021 have a tendency to return to its original position, preparing for the locking action. When the window is opened, the spring 204 is in an extended state. During the automatic closing process, the spring 204 is also in an extended state. After the window is manually locked, the spring 204 is in a compressed state. During the initial stage of the window opening process and when manually closing and locking, the spring 204 is compressed to the middle position and springs back to the initial position after opening.

[0024] It also includes a lock base 3, which is fixed to the bottom of the window frame. Symmetrically arranged limiting strips 303 are fixed to the upper center of the lock base 3, forming a track groove. A locking point 301 is slidably disposed within the track groove. The locking point 301 is an L-shaped block with symmetrical slots. The locking point 301 and the lock base 3 are connected by bolts. The lower side of the locking point 301 is serrated, and the bottom of the track groove is a serrated groove that fits the lower side of the locking point 301. When the window is closed, the cylinder 2051 on the upper side of the end of the moving rod 205 will be behind the locking point 301, thus forming a locking point.

[0025] In this embodiment, when the window sash is closed, the lever 2021 on the transmission rod assembly 2 engages with the locking point 301 to achieve locking. Different window sashes may have different closing positions. The adjustable design of the locking point 301 ensures that the lever 2021 can accurately engage with the locking point 301 to achieve reliable locking. The lock seat 3 is fixed to the bottom of the window frame. The track groove formed by its limiting strip 303 engages with the slidably adjustable L-shaped locking point 301. Through bolt connection and the serrated design of the lower side of the locking point 301 and the bottom of the track groove, the position of the locking point 301 can be adjusted to adapt to the closing position requirements of different window sashes. This ensures that when the window sash is closed, the lever 2021 can accurately engage with the locking point 301 to complete the locking action, enhancing the versatility and stability of the device.

[0026] The lock base 3 has a stop edge 302 fixedly provided at both ends on one side. The stop edge 302 is provided corresponding to the lever 2021. The lever 2021 can abut against the side wall of the stop edge 302 corresponding to the moving rod 205.

[0027] In this embodiment, the stop edge 302 is provided with a corresponding lever 2021. When the window sash is closed, the lever 2021 moves with the transmission rod assembly 2. When the window sash is fully closed, the lever 2021 abuts against one side of the stop edge 302 (e.g., Figure 5 As shown in the figure, the spring 204 is compressed at this time. At this time, the contact between the lever 2021 and the stop 302 restricts the window sash from opening outward. The mechanical blocking principle is used to lock the window sash and prevent strong wind from blowing it open.

[0028] The lever 2021 is arc-shaped. During contact and engagement with the baffle 302, the arc-shaped lever 2021 reduces stress concentration during contact compared to other shapes, making the contact smoother. When the window sash is closed, it is easier to slide into the predetermined position of the baffle 302 to lock, reducing the probability of jamming or inaccurate locking due to shape issues, and improving the stability and reliability of the device.

[0029] The side of the retaining edge 302 facing away from the lever 2021 is an arc surface or a downwardly sloping surface. This shape, where the retaining edge 302 faces away from the lever 2021, serves as a guide as the lever 2021 approaches the retaining edge 302 during window closing. When the lever 2021 approaches the retaining edge 302, it slides more easily along the arc surface or slope into the area where the retaining edge 302 and the lever 2021 engage, thus achieving locking.

[0030] The flange 302 is L-shaped and the flanges 302 at both ends are symmetrically arranged.

[0031] The method of using this utility model is as follows:

[0032] Install the moving rod 205 into the standard slot in the bottom frame 1 of the top-hung window, and complete the assembly of each component of the transmission rod assembly 2 (slide rail 201, slider 202, lever 2022, lever 2022 shaft, block 203, and spring 204); fix the lock seat 3 to the bottom of the window frame, adjust the position of the L-shaped locking point 301 in the track groove so that it can adapt to the closing position of the corresponding window sash, and fix the locking point 301 to the lock seat 3 with bolts. When the top-hung window is in normal use, the device is in the initial state, the lever 2021 is not in contact with the stop 302, at this time the lever 2021 is outside the stop 302, the arc-shaped wall surface of the lever 2021 is in contact with the inclined or arc surface of the stop 302, and the window sash can be opened and closed freely. At this time, the lever 2021 and the stop 302 are in the following state. Figure 1 As shown, spring 204 is in a stretched state. When encountering strong winds, the strong winds push the window sash to close, causing the window sash to move the moving rod 205. The moving rod 205, through the cooperation of the slide rail 201 and the slider 202, causes the slider 202 to slide within the slide rail 201, thereby driving the lever 2022. The force of the spring 204 returning to its original position causes the lever 2021 to have a tendency to return to its original position. When the window sash is fully closed, under the elastic force of the spring 204, the lever 2021 abuts against the side wall of the retaining edge 302 (e.g., Figure 5 As shown, the contact between the lever 2021 and the stop 302 restricts the window sash from opening outward, thus locking the window sash and preventing strong winds from blowing it open. If you need to open the window sash, manually apply external force to disengage the lever 2021 from the contact state with the stop 302 and return it to its original position. The spring 204 is stretched, releasing the lock, and the window sash can then be opened normally.

[0033] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
