Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to an aluminum alloy door and window with good sealing performance. Background Technology

[0002] With increasing global emphasis on building energy conservation, doors and windows, as the weakest link in the building envelope, are facing increasingly stringent requirements for airtightness and thermal insulation. The frequent occurrence of extreme weather events such as typhoons, rainstorms, and sandstorms is driving the upgrading of doors and windows towards higher airtightness and wind pressure resistance to reduce rainwater leakage, air infiltration, and noise pollution. Aluminum alloy doors and windows with better airtightness refer to aluminum alloy door and window products that significantly improve airtightness, watertightness, and sound insulation through means such as profile structure optimization, sealing material upgrades, and process refinement.

[0003] However, existing aluminum alloy doors and windows with good sealing performance have the following disadvantages:

[0004] (1) Traditional aluminum alloy doors and windows mostly use fixed sealing strips. The strips are prone to cracking due to thermal expansion and contraction of the profile, installation errors or long-term aging, resulting in air leakage and rainwater backflow, causing indoor energy loss and mold on the walls.

[0005] (2) Existing aluminum alloy doors and windows with good sealing performance are usually integrated, and the guardrails are difficult to adapt to the policy standard upgrade. The old guardrails need to be removed and reinstalled, resulting in a waste of resources.

[0006] Therefore, this utility model provides an aluminum alloy door and window with better sealing performance. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem solved by this utility model is to provide a more practical aluminum alloy door and window with better sealing performance, which solves the problems mentioned in the background art, such as the easy cracking of the rubber strip due to thermal expansion and contraction of the profile, installation errors or aging and cracking after long-term use, and the difficulty of the guardrail adapting to policy and standard upgrades.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: an aluminum alloy door and window with good sealing performance, comprising a door and window, characterized in that: a glass frame is installed on the front of the door and window via hinges, and a sealing component is provided on the inner side wall of the door and window;

[0011] The sealing assembly includes an installation frame installed on the inside of the door or window. A protective component is provided on the inner wall of the installation frame. A rectangular groove is opened on the front of the installation frame. A sliding block is movably connected to the inner wall of the rectangular groove. A spring is connected between the back of the sliding block and the inner wall of the rectangular groove. A fixing plate is fixedly connected to the front of the sliding block.

[0012] The protective component includes multiple mounting blocks fixedly connected to the inner sidewall of the mounting frame. A T-shaped groove is provided on the front of each mounting block, and a T-shaped slider is slidably connected to the inner sidewall of the T-shaped groove. A protective rod is fixedly connected to the opposite side of two T-shaped sliders.

[0013] Optionally, a countersunk hole is provided on one side of the mounting block, and a screw is provided on the inner wall of the countersunk hole. A threaded hole adapted to the screw is provided on one side of the T-shaped slider. The screw passes through the countersunk hole and is screwed into the threaded hole of the T-shaped slider to form a mechanical engagement, preventing the guard rod from shifting in the horizontal direction.

[0014] Optionally, a sealing gasket is fixedly connected to the front of the fixing plate. The front of the sealing gasket contacts the back of the glass frame. The elasticity of the sealing gasket can adapt to the small tolerances between the glass frame and the door / window, filling the gaps of traditional rigid connections and improving airtightness.

[0015] Optionally, a limiting block is fixedly connected to one side of the sliding block, and a limiting groove adapted to the limiting block is provided on the inner side wall of the rectangular groove. The limiting block is movably connected to the inner side wall of the limiting groove. The cooperation between the limiting block and the limiting groove forms a sliding track, ensuring that the sliding block moves only in the horizontal direction during spring compression or rebound, avoiding deviation or jamming.

[0016] Optionally, a washer is fitted on the surface of the screw, with one side of the washer contacting the inner wall of the countersunk hole. The washer disperses the axial force of the screw to the surface of the mounting block, reducing local pressure and preventing the countersunk hole from cracking due to stress concentration.

[0017] Optionally, a mounting base is installed on the back of the glass frame, and a handle is fixedly connected to one side of the mounting base. The handle is positioned close to the edge of the glass frame, using the lever principle to reduce the force required for opening and closing, thereby reducing user fatigue.

[0018] (III) Beneficial Effects

[0019] This utility model provides an aluminum alloy door and window with good sealing performance, which has the following beneficial effects:

[0020] 1. In this well-sealed aluminum alloy door and window, the spring is compressed when the glass frame is closed, generating a continuous elastic reaction force, which ensures that the sealing gasket always adheres to the glass frame with constant pressure. This design can automatically compensate for slight deformation of the door and window profiles caused by temperature changes or long-term use, and avoid the problems of air leakage and water seepage caused by gaps due to structural displacement of traditional fixed sealing strips.

[0021] 2. This aluminum alloy door and window with good sealing performance can complete the installation or removal of the guardrail in minutes through the cooperation of screws and threaded holes, without the need for professional tools. It is convenient for users to flexibly adjust according to seasonal or scene requirements. The cooperation of T-shaped slider and slide groove forms a horizontal limit, and screws provide vertical locking force. Double fixation ensures that the guardrail does not shake or fall off, and the safety performance is better than traditional welded or snap-on guardrails. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4 The present invention provides a technical solution: an aluminum alloy door and window with good sealing performance, including a door and window 1, characterized in that: a glass frame 102 is installed on the front of the door and window 1 through a hinge 101, and a sealing component 2 is provided on the inner side wall of the door and window 1;

[0029] The sealing assembly 2 includes a mounting frame 201 installed inside the door and window 1. A protective assembly 3 is provided on the inner wall of the mounting frame 201. A rectangular groove is provided on the front of the mounting frame 201. A sliding block 202 is movably connected to the inner wall of the rectangular groove. A spring 203 is connected between the back of the sliding block 202 and the inner wall of the rectangular groove. The spring 203 is compressed to generate an elastic reaction force, which pushes the sealing gasket 4 to fit tightly against the back of the glass frame 102 to form a dynamic sealing barrier. A fixing plate 204 is fixedly connected to the front of the sliding block 202.

[0030] The protective component 3 includes multiple mounting blocks 301 fixedly connected to the inner wall of the mounting frame 201. The front of the mounting block 301 is provided with a T-shaped groove. A T-shaped slider 302 is slidably connected to the inner wall of the T-shaped groove. A protective rod 304 is fixedly connected to the opposite side of two T-shaped sliders 302. The protective rod 304 slides in the T-shaped groove through the T-shaped sliders 302 to achieve multiple functions such as anti-theft, anti-fall and ventilation.

[0031] A countersunk hole is provided on one side of the mounting block 301, and a screw 303 is provided on the inner wall of the countersunk hole. A threaded hole that matches the screw 303 is provided on one side of the T-shaped slider 302. The screw 303 passes through the countersunk hole and is screwed into the threaded hole of the T-shaped slider 302 to form a mechanical engagement, preventing the guard rod 304 from shifting in the horizontal direction.

[0032] A sealing gasket 4 is fixedly connected to the front of the fixing plate 204. The front of the sealing gasket 4 contacts the back of the glass frame 102. The elasticity of the sealing gasket 4 can adapt to the small tolerance between the glass frame 102 and the door and window 1, fill the gap of the traditional rigid connection, and improve the airtightness.

[0033] A limiting block 5 is fixedly connected to one side of the sliding block 202. A limiting groove adapted to the limiting block 5 is opened on the inner side wall of the rectangular groove. The limiting block 5 is movably connected to the inner side wall of the limiting groove. The cooperation between the limiting block 5 and the limiting groove forms a sliding track, ensuring that the sliding block 202 moves only in the horizontal direction during the compression or rebound of the spring 203, avoiding deviation or jamming.

[0034] A washer 6 is fitted on the surface of screw 303. One side of washer 6 contacts the inner wall of countersunk hole. Washer 6 disperses the axial force of screw 303 to the surface of mounting block 301, reduces local pressure, and prevents countersunk hole from cracking due to stress concentration.

[0035] A mounting base is installed on the back of the glass frame 102, and a handle 7 is fixedly connected to one side of the mounting base. The handle 7 is located near the edge of the glass frame 102, and the lever principle is used to reduce the force required to open and close, thereby reducing fatigue during use.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: When the glass frame 102 is closed, the pressing fixing plate 204 causes the sliding block 202 to slide in the rectangular groove, compressing the spring 203. The elastic reaction force of the spring 203 is transmitted to the sealing gasket 4 through the fixing plate 204, so that it fits tightly against the back of the glass frame 102 to form a sealing barrier.

[0038] The second step: The protective rod 304 slides in the T-shaped groove of the mounting block 301 via the T-shaped slider 302. The protective rod 304 can be installed as needed. After the protective rod 304 is moved into place, the screw 303 is screwed into the threaded hole of the T-shaped slider 302 to lock the protective rod 304 in a specific position, forming a protective barrier.
