Description

Technical Field

[0001] This utility model relates to the technical field of door and window components, and in particular to a windproof structure for doors and windows. Background Technology

[0002] As a key component of building structure, doors and windows serve the functions of separating spaces, circulating air, regulating temperature and humidity, and ensuring safety. They act as a medium for interaction between indoor and outdoor environments. Based on their fundamental role, modern doors and windows emphasize windproof structural design, reducing the risk of wind and rain penetration by improving airtightness, enhancing stability to ensure residential safety, and adapting to the needs of changing climate environments.

[0003] The operating principle of windproof structures for doors and windows mainly relies on the sealing material to press and block airflow penetration, combined with the rigid support of the frame to resist wind pressure deformation. Windproof structures for doors and windows achieve wind resistance through multiple glass spacers, reinforced profile locking points, and elastic sealing strips filling gaps. However, in actual use, the above devices suffer from problems such as aging of sealing materials leading to weakened air tightness, frame deformation causing a decrease in support force, and a lack of decentralized design in areas where wind force is concentrated.

[0004] The existing structure lacks a deflector assembly, which prevents it from reducing local wind pressure intensity by altering the airflow path. Consequently, the pressure on the window cannot be effectively distributed under strong wind conditions, affecting the overall windproof stability and durability. Therefore, a windproof structure for doors and windows is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a windproof structure for doors and windows, which aims to improve the problem in the prior art that the local wind pressure intensity cannot be reduced by changing the airflow path, resulting in the window body not being able to effectively decompose the pressure under strong wind conditions.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a windproof structure for doors and windows, comprising a frame, pulleys, and connecting blocks. A motor is fixedly connected to the top of the outer wall of the frame. Two sliding grooves are opened on the inner wall of the frame. A fixed rod is rotatably connected to the adjacent side of a plurality of pulleys. A first horizontal plate is fixedly connected to the outer wall of a plurality of fixed rods.

A plurality of first hollow columns are slidably connected to the outer wall of the lead screw. A plurality of second hollow columns are slidably connected to the outer wall of the lead screw. A plurality of second springs are slidably connected to the outer wall of the lead screw. A push plate is threadedly connected to the outer wall of the lead screw. A plurality of buffer mechanisms 2 are provided on the front side of the outer wall of the frame. The buffer mechanisms are used to prevent strong winds from directly affecting the window.

[0014] This utility model has the following beneficial effects:

[0015] 1. In the initial state of this utility model, the first horizontal plate and the second horizontal plate are in a retracted state. When it needs to be started, the motor is started, which drives the lead screw. Then the push plate moves upward, and the first horizontal plate and the second horizontal plate also unfold.

Multiple buffer mechanisms 2 are provided on the front side of the outer wall of frame 1. The buffer mechanisms 2 are used to prevent strong winds from directly affecting the window. Motor 3 is used to drive lead screw 8 to rotate, thereby driving push plate 9 to move up and down.

Several buffer mechanisms 2 are arranged on the front outer wall of the frame 1 to reduce the direct impact effect of strong wind on the window structure. The motor 3 drives the lead screw 8 to rotate, thereby driving the push plate 9 to perform lifting and lowering actions and thus adjusting the spatial position of the flow guiding plate.

A drainage groove 23 is provided on the outer wall of the frame 24 to guide rainwater or condensation outwards. A protective frame 16 is fixedly connected to the inner wall of the frame 24. This protective frame is used to fix and support the window sash, protect the edge of the window opening, enhance structural stability, and prevent water seepage and air leakage. Glass 17 is fixedly connected to the inner wall of the protective frame 16. Its main functions are to allow light to pass through, isolate wind and rain, separate indoor and outdoor spaces, and maintain a clear view. The front side of the outer wall of the protective frame 16 is fixedly connected to... The window is connected to a base 18, and a handle 19 is fixedly connected to the front side of the outer wall of the base 18 to facilitate the opening and closing of the window. The base 18 is used to reinforce the handle 19. The handle 19 has a groove 22. The outer wall of the frame 24 has a fixing groove 21.

The mother shaft 14 and the daughter shaft 15 cooperate with each other and are the core components for opening and closing the window.

[0030] Specifically, the front end of the connecting block 25 is rigidly connected to the frame 24. The frame 24 serves as the basic structure of the window, supporting the overall frame 1. Drainage grooves 23 are provided on the outer surface of the frame 24 to guide rainwater and condensate to the outside. The inner wall of the frame 24 is fixedly fitted with a protective frame 16 to provide positioning and support for the window sash. The protective frame 16 serves as a protective structure for the edge of the window opening, enhancing stability and preventing water seepage and air leakage. The inner wall of the protective frame 16 is fitted with glass 17, which serves to transmit light, prevent water seepage, and separate indoor and outdoor spaces. The front outer wall of the protective frame 16 is connected to the bottom... The base 18 is rigidly connected, and the handle 19 is installed on the front end of the base 18 to provide a fulcrum for opening and closing the window sash. The base 18 also serves as a reinforcement for the handle 19. The outer wall of the frame 24 is designed with a fixing groove 21 as a structural interface. The outer wall of the protective frame 16 is covered with a sealing gasket 20 to improve the sealing performance of the window and prevent rainwater infiltration and air leakage. The outer wall of the protective frame 16 is equipped with a mother shaft 14 as a rotation hub. The surface of the mother shaft 14 and the daughter shaft 15 form a rotating joint linkage structure. The mother shaft 14 and the daughter shaft 15 work together to form the core drive unit for opening and closing the window sash.

[0031] Working principle: First, in the initial state, the first horizontal plate 12 and the second horizontal plate 13 are folded and stored. When the system needs to enter the windproof working mode, the motor 3 is activated to drive the lead screw 8 to rotate. The rotation of the lead screw 8 drives the push plate 9 to perform axial displacement. During the upward movement of the push plate 9 along the surface of the lead screw 8, the first hollow column 10 and the second hollow column 11 are pushed vertically upward. The first hollow column 10 and the second hollow column 11 respectively pull the first horizontal plate 12 and the second horizontal plate 13 to unfold along the slide 5 to the working position. After unfolding, the guide plate effectively decomposes the wind pressure load on the window by changing the airflow path. The wind pressure resistance of the window structure is significantly optimized, and the overall wind resistance performance and long-term use stability are systematically improved.

[0032] Furthermore, the outer surfaces of several first fixing blocks 201 are rigidly connected to the inner wall of the frame 1. The first fixing blocks 201 and the second fixing blocks 202 respectively achieve the connection task of the frame 24 and the two sides of the frame 1. The outer surfaces of multiple first fixing blocks 201 are processed with buffer grooves 205 as the linear movement path of the sliding column 203. Each buffer groove 205 is embedded with the sliding column 203 and maintains the axial displacement function. The outer surface of the sliding column 203 is equipped with a first spring 204 to store elastic potential energy to support the vibration attenuation mechanism of the buffer mechanism 2. The front end face of the sliding column 203 and the second fixing block 202 are welded to form a linkage structure. The inner wall of the sliding column 203 is covered with a wear-resistant layer 206 to improve its anti-friction and wear resistance. The inner wall of each wear-resistant layer 206 is densely bonded with the support layer 207. The support layer 207 serves as the base bearing body of the sliding column 203. The entire system provides a certain buffer force for the window body, thereby avoiding damage to it from the direct stress when strong winds strike.
