Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary accessories for aluminum alloy doors and windows, specifically an aluminum alloy door and window anti-leakage component. Background Technology

[0002] In interior decoration, aluminum alloy doors and windows are favored due to their superior performance. Large aluminum alloy sliding doors and windows are often used as a partition between bedrooms and balconies. In winter, these doors and windows block cold air from the balcony, preventing it from entering the bedroom to some extent. However, since most aluminum alloy sliding doors and windows move by sliding on tracks installed on the ground using rollers, a gap inevitably forms between the bottom of the door / window and the ground. Cold air from the balcony can easily enter the bedroom through this gap, causing the bedroom temperature to drop further. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an aluminum alloy door and window anti-leakage component, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy door and window anti-leakage component, comprising an aluminum alloy sliding door and window, wherein a fixing plate is fixedly installed on the front side wall of the lower frame of the aluminum alloy sliding door and window, and a plurality of recessed notches are evenly opened from left to right on the front edge of the upper side wall of the fixing plate, and a spring fixing rod is fixedly connected to the bottom of the recessed notch, and a nut is screwed on the top of the spring fixing rod. A first spring and a second spring are respectively fitted on the upper and lower sides of the spring fixing rod, wherein the first spring is longer than the second spring. An L-shaped movable piece is slidably fitted on the front side wall of the fixing plate, and a T-shaped slot is opened at the lower end of the L-shaped movable piece, and a sealing strip is inserted into the T-shaped slot.

[0005] Furthermore, threaded holes are respectively opened on the left and right sides and the middle of the front side wall of the lower frame of the aluminum alloy sliding door and window.

[0006] Furthermore, fixing ears are fixedly connected to the middle part of the rear side wall of the L-shaped movable piece corresponding to the part of the spring fixing rod, and the fixing ears are fitted onto the spring fixing rod between the first spring and the second spring.

[0007] Furthermore, fixing holes are respectively opened on the left and right sides and the middle of the front sidewall of the fixing plate.

[0008] Furthermore, the upper end of the sealing strip is a T-shaped insert, and the lower end of the T-shaped insert is fixedly connected to a soft windbreak sheet.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: by installing the air-leakage prevention component on the lower frame of the aluminum alloy door and window, the fixed plate and the L-shaped movable plate that slides against its surface, and the sealing strip inserted at the lower part of the L-shaped movable plate, under the action of the first spring, the L-shaped movable plate drives the sealing strip at its lower part to press against the ground, thereby blocking and sealing the gap between the lower end of the aluminum alloy door and window and the ground due to the installation of the guide wheel, thus preventing cold air from entering the room through the gap, and thus playing a certain role in preventing air leakage.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a technical solution: an aluminum alloy door and window anti-leakage component, including an aluminum alloy sliding door and window 1. Threaded holes 11 are respectively opened on the left and right sides and the middle of the front side wall of the lower frame of the aluminum alloy sliding door and window 1. A fixing plate 2 is fixedly installed on the front side wall of the lower frame of the aluminum alloy sliding door and window 1 through the threaded holes 11. Several countersunk notches 21 are evenly opened from left to right on the front edge of the upper side wall of the fixing plate 2. A spring fixing rod 22 is fixedly connected upwards to the bottom of the countersunk notches 21. A nut 23 is screwed onto the top of the spring fixing rod 22. Fixing countersunk holes 24 are respectively opened on the left and right sides and the middle of the front side wall of the fixing plate 2. A first spring 3 and a second spring 4 are respectively fitted onto the upper and lower parts of the spring fixing rod 22. The first spring 3 is larger than the second spring. 4. The front side wall of the fixing piece 2 is slidably fitted with an L-shaped movable piece 5. A T-shaped slot 51 is opened at the lower end of the L-shaped movable piece 5. The middle part of the rear side wall of the L-shaped movable piece 5 is fixedly connected to the spring fixing rod 22. The fixing ear 52 is fitted onto the spring fixing rod 22 between the first spring 3 and the second spring 4. A sealing strip 6 is inserted into the T-shaped slot 51. The upper end of the sealing strip 6 is a T-shaped insert 61. The lower end of the T-shaped insert 61 is fixedly connected to a soft windshield 62.

[0016] In use: Install the component on the front side wall of the lower frame of the aluminum alloy sliding door / window 1. If the aluminum alloy sliding door / window 1 faces outwards, install the component on the outward-facing side of its lower frame. If the aluminum alloy sliding door / window 1 faces inwards, install the component on the inward-facing side of its lower frame. This prevents interference between the component and the left and right aluminum alloy sliding doors / windows 1 when they are pushed and pulled together. During installation, align the fixing piece 2 with the corresponding threaded hole 11 and use threaded nails to fix it to the surface of the lower frame of the aluminum alloy sliding door / window 1. Then, install the second spring 4 onto the spring fixing rod 22. Then, insert the sealing strip 6 into the T-shaped slot 51 at the bottom of the L-shaped movable piece 5. Finally, install the L-shaped... The movable piece 5 is fitted onto the corresponding spring fixing rod 22 through its fixing ear 52 corresponding to the groove notch 21. Then, the first spring 3 is fitted onto the spring fixing rod 22 on the upper part of the fixing ear 52. After that, the nut 23 is screwed on. Under the elastic force of the first spring 3, the L-shaped movable piece 5 is pressed down along the fixed piece 2, so that the soft windproof piece 62 is pressed and adhered to the ground, thereby blocking the gap between the bottom of the aluminum alloy sliding door and window 1 and the ground, preventing cold air from entering the house. During the process of sliding the aluminum alloy sliding door and window 1, the soft windproof piece 62 wears on the ground. Under the action of the first spring 3, the soft windproof piece 62 can still be kept in contact with the ground surface.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
