Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, specifically to an adjustable safety door and window gap. Background Technology
[0002] Doors and windows are classified as enclosure components or partition components according to their location. They have different design requirements and must have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fireproofing. New requirements include energy conservation, and the airtightness of doors and windows is an important part of energy-saving design. Doors and windows are important components of the building envelope system.
[0003] Currently, most doors and windows can only be locked when closed. When a small gap is needed for ventilation, the windows cannot be locked, posing a certain safety hazard.
[0004] To avoid such problems, Chinese Patent CN221646685U discloses an adjustable safety window gap, including a window frame. An adjustment mechanism is provided on one side of the window frame, a stabilizing component is provided on one side of the adjustment mechanism, a dustproof component is provided on one side of the stabilizing component, and a reinforcing component is provided on one side of the adjustment mechanism. This application, by incorporating the adjustment mechanism, stabilizing component, dustproof component, and reinforcing component, allows for easy adjustment of the window gap. When adjustment is needed, the pulling column is first pulled, causing the fixed column to retract into the sliding cylinder. Then, the sliding cylinder is slid within the sliding groove to a suitable position. Releasing the pulling column causes the spring to apply elastic force to the fixed column, causing it to pop out of the fixed cylinder and insert into the fixed groove to secure it. When the sliding window is pulled, it will be blocked by the fixed column and unable to close. The size of the window gap can be changed by adjusting the position of the sliding cylinder. The structure is simple and easy to use, improving usability.
[0005] While the above-mentioned devices facilitate blocking and changing the size of window gaps, they inevitably have shortcomings in actual use. For example, the lack of a limiting mechanism makes it difficult to fix the window opening, and the window may slide freely during the gap period. To avoid such problems, an adjustable safety door and window gap device is proposed to solve the existing problems. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides an adjustable safety door and window gap, which solves the problem of the lack of a limiting mechanism in the device, making it inconvenient to fix the window opening and causing the window to slide freely during the gap period.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable safety door and window gap, comprising a door and window frame and a window frame, wherein two window frames are provided, and the two window frames are respectively offset and slidably disposed on both sides of the inner cavity of the door and window frame, the interior of the window frame is fitted with glass, and a handle is fixedly connected to the front side of the front window frame, both sides of the inner cavity of the handle are provided with sliding grooves, and a sliding plate is slidably connected between the two sliding grooves, and a first spring is fixedly connected between adjacent sliding grooves and sliding plates, and a pin block is fixedly connected to the bottom of the sliding plate through a bracket, and a plurality of pin slots for matching the pin blocks are equidistantly provided on the front side of the door and window frame.
[0008] Preferably, gears are rotatably provided at the top and bottom of the inner cavity of the door and window frame via a rotating shaft, and several tooth limit blocks that mesh with the gears are fixedly provided at the top and bottom of the opposite side of the two window frames via slots.
[0009] Preferably, storage slots are provided on both sides of the inner cavity of the door and window frame at different angles. A window screen frame is slidably connected inside the storage slot. A second spring is fixedly connected between the window screen frame and the storage slot, and two second springs are arranged symmetrically at the top and bottom. Beneficial effects
[0010] This invention provides an adjustable safety door / window gap. Compared with existing technologies, it has the following advantages: This invention provides a handle on the front window frame, and a sliding plate, a latch block, and a latch groove between the handle and the door / window frame. This allows the window frame to be easily fixed and limited during the gap period, preventing random sliding. Furthermore, toothed limit blocks and gears are provided between the two window frames and the door / window frame, facilitating centralized control of the sliding of the two window frames. Additionally, window screen frames are offset and slidably installed on both sides of the inner cavity of the door / window frame, creating a gap between the window frame and the door / window frame, allowing dust to be filtered by the window screen frame.

[0020] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figure 1-8 This utility model provides a technical solution: an adjustable safety door and window gap, including a door and window frame 1 and a window frame 2. There are two window frames 2, and the two window frames 2 are respectively offset and slidably arranged on both sides of the inner cavity of the door and window frame 1. Glass 3 is installed inside the window frame 2.
[0022] Furthermore: To facilitate the fixing and limiting of the window gap between the front window frame 2 and the door and window frame 1, a handle 4 is fixedly connected to the front side of the front window frame 2. The handle 4 has a sliding groove 5 on both sides of its inner cavity. A sliding plate 6 is slidably connected between the two sliding grooves 5. A first spring 7 is fixedly connected between adjacent sliding grooves 5 and sliding plate 6. A pin block 8 is fixedly connected to the bottom of the sliding plate 6 through a bracket. Several pin slots 9 that are used in conjunction with the pin blocks 8 are equidistantly opened on the front side of the door and window frame 1.
[0023] Furthermore, to facilitate simultaneous operation of the two window frames 2, gears 10 are rotatably installed at the top and bottom of the inner cavity of the window frame 1 via a rotating shaft, and several tooth limit blocks 11 that mesh with the gears 10 are fixedly installed at the top and bottom of the opposite side of the two window frames 2 via slots.
[0024] Furthermore: In order to facilitate the isolation of dust from the gap passage, storage slots 12 are staggered on both sides of the inner cavity of the door and window frame 1. A window screen frame 13 is slidably connected inside the storage slot 12. A second spring 14 is fixedly connected between the window screen frame 13 and the storage slot 12, and two second springs 14 are symmetrically arranged at the top and bottom.
[0025] When in use, grip the slide plate 6 and handle 4 tightly. The slide plate 6 will be forced to disengage the latch block 8 from the latch groove 9. Then slide the front window frame 2 until the gap between the window frame 2 and the side of the door and window frame 1 is adjusted to the appropriate size. Then release the slide plate 6, which will cause the slide plate 6 to move the latch block 8 back to its original position. The reset latch block 8 will engage with the latch groove 9 at the current position.
[0026] When the front window frame 2 moves, it will cause the rear window frame 2 to move synchronously in the opposite direction through the meshing of the tooth limit block 11 and the gear 10.
[0027] When the window frame 2 is close to the side of the door and window frame 1, the window frame 2 simultaneously presses against the window screen frame 13.
