Description

Technical Field

[0001] The utility model relates to the technical field of buffering, in particular to a buffering device for aluminum alloy doors and windows. Background Art

[0002] Aluminum alloy windows are windows with frames and sashes made of aluminum alloy architectural profiles. They are categorized as standard aluminum alloy doors and windows and thermally insulated aluminum alloy doors and windows. Aluminum alloy windows are aesthetically pleasing, airtight, and highly strong, making them widely used in construction projects. In home renovations, they are often used to enclose balconies. Furthermore, aluminum alloy is easy to extrude, and the profiles offer precise cross-sectional dimensions and high machining accuracy. Therefore, many homeowners choose aluminum alloy doors and windows for their renovations. During use, aluminum alloy windows can often collide with the aluminum alloy frame due to excessive force applied by the user, easily causing deformation and damage to the windows, as well as generating significant noise. Patent application number CN202121226612.4 proposes a buffer structure for aluminum alloy doors and windows. While this structure provides some cushioning for the aluminum alloy windows, it only provides a one-time cushioning effect, resulting in limited effectiveness. Furthermore, the windows are prone to rebounding under the reaction force of the buffer structure, which can affect their normal opening or closing. Therefore, improvements are needed. Utility Model Content

[0003] The main purpose of the utility model is to provide a buffer device for aluminum alloy doors and windows, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A buffer device for aluminum alloy doors and windows, including a friction buffer assembly, which is installed in an aluminum alloy window frame. The friction buffer assembly consists of a friction base plate, a No. 1 spring and a connecting block. There are two No. 1 springs and both are fixedly installed at the lower end of the friction base plate. There are two connecting blocks and both are fixedly installed at the inner and outer ends of the friction base plate respectively. A blocking buffer assembly is installed on the friction base plate, and the blocking buffer assembly consists of a baffle, a hemispherical airbag, a connecting plate, an anti-slip plate and a No. 2 spring. There are two hemispherical airbags and both are fixedly installed at the outer end of the baffle. The connecting plate is fixedly installed at the lower end of the baffle. The anti-slip plate is fixedly installed at the lower end of the connecting plate. The No. 2 spring is fixedly installed at the inner end of the anti-slip plate.

[0006] Preferably, an installation and storage groove is provided on the lower side wall of the aluminum alloy window frame, and two anti-detachment guide rail grooves are symmetrically provided on the inner wall of the installation and storage groove. An aluminum alloy sliding window is movably installed in the friction buffer assembly.

[0007] Preferably, the friction base plate on the friction buffer assembly is slidably installed in the installation receiving groove, a connecting guide groove is opened inside the friction base plate, and a connecting guide groove is opened at the upper end of the friction base plate, and the connecting guide groove and the connecting guide groove are connected to each other.

[0008] Preferably, the connecting block on the friction buffer assembly is slidably installed up and down in the anti-slip guide rail groove, the No. 1 spring is located in the installation receiving groove, and the No. 1 spring is fixedly connected to the lower inner wall of the installation receiving groove.

[0009] Preferably, the baffle on the blocking and buffering assembly is located at the upper end of the friction base plate, the connecting plate is slidably installed inside and outside the connecting guide groove, and the anti-detachment plate is slidably installed inside and outside the connecting guide groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up a buffer device consisting of a friction buffer assembly and a blocking buffer assembly, the aluminum alloy sliding window can be buffered twice, resulting in a better buffering effect. At the same time, under the elastic force of the No. 1 spring on the friction buffer assembly, the friction plate will be in close contact with the aluminum alloy sliding window, thus increasing the resistance to the movement of the aluminum alloy sliding window. Consequently, the closed aluminum alloy sliding window is less likely to rebound under the reaction force of the buffer device, allowing the aluminum alloy sliding window to open or close normally.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a buffer device for aluminum alloy doors and windows includes a friction buffer assembly 1, which is installed inside an aluminum alloy window frame 3. The friction buffer assembly 1 consists of a friction base plate 7, a first spring 8, and a connecting block 9. There are two first springs 8, both of which are fixedly installed at the lower end of the friction base plate 7. There are two connecting blocks 9, which are respectively fixedly installed at the inner and outer ends of the friction base plate 7. An installation and storage groove 5 is provided on the lower side wall of the aluminum alloy window frame 3. Two anti-detachment guide rail grooves 6 are symmetrically provided on the inner wall of the installation and storage groove 5. An aluminum alloy sliding window 4 is movably installed inside the friction buffer assembly 1. The friction base plate 7 on the friction buffer assembly 1 is slidably installed up and down in the installation and storage groove 5. A connecting guide rail groove 10 is provided inside the friction base plate 7. A connecting guide rail groove 11 is provided at the upper end of the friction base plate 7. The connecting guide rail groove 10 and the connecting guide rail groove 11 are interconnected. The connecting block 9 on the friction buffer assembly 1 is slidably installed up and down in the anti-detachment guide rail groove 6. The first spring 8 is located in the installation and storage groove 5 and is fixedly connected to the lower inner wall of the installation and storage groove 5.

[0020] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, a blocking and buffering assembly 2 is installed on the friction base plate 7. The blocking and buffering assembly 2 consists of a baffle 12, a hemispherical airbag 13, a connecting plate 14, an anti-detachment plate 15, and a second spring 16. There are two hemispherical airbags 13, both of which are fixedly installed on the outer end of the baffle 12. The connecting plate 14 is fixedly installed on the lower end of the baffle 12. The anti-detachment plate 15 is fixedly installed on the lower end of the connecting plate 14. The second spring 16 is fixedly installed on the inner end of the anti-detachment plate 15. The baffle 12 on the blocking and buffering assembly 2 is located at the upper end of the friction base plate 7. The connecting plate 14 is slidably installed inside and outside the connecting guide groove 11. The anti-detachment plate 15 is slidably installed inside and outside the connecting guide groove 10. The second spring 16 on component 2 is located inside the connecting guide groove 10, and the second spring 16 is fixedly connected to the inner wall of the connecting guide groove 10. By setting a buffer device consisting of friction buffer component 1 and blocking buffer component 2, the aluminum alloy sliding window 4 can be buffered twice, thus achieving a better buffering effect. At the same time, under the elastic force of the first spring 8 on the friction buffer component 1, the friction base plate 7 will be in close contact with the aluminum alloy sliding window 4, thus making the resistance to the movement of the aluminum alloy sliding window 4 greater. Consequently, the closed aluminum alloy sliding window 4 is less likely to rebound under the reaction force of the buffer device, allowing the aluminum alloy sliding window 4 to open or close normally.

[0021] It should be noted that this utility model is a buffer device for aluminum alloy doors and windows. When the aluminum alloy sliding window 4 is pushed, the aluminum alloy sliding window 4, which moves towards the side wall of the aluminum alloy window frame 3, will contact the friction base plate 7 on the friction buffer assembly 1. At this time, as the aluminum alloy sliding window 4 moves, the friction base plate 7 will be completely pushed into the installation and storage groove 5. During this process, the downward moving friction base plate 7 will compress the first spring 8. At the same time, under the elastic reaction force of the first spring 8, the friction base plate 7 will generate a large friction force with the aluminum alloy sliding window 4, thereby slowing down the moving speed of the aluminum alloy sliding window 4. Then, when the aluminum alloy sliding window 4 continues to move, it will contact the baffle 12 on the blocking buffer assembly 2. At this time, the aluminum alloy sliding window 4 will push the baffle 12. The sliding window 4 moves towards the side wall of the aluminum alloy window frame 3. As the baffle 12 moves, the second spring 16 is stretched. During the stretching and deformation of the second spring 16, the elastic reaction force generated by the second spring 16 further slows down the moving speed of the aluminum alloy sliding window 4. When the hemispherical airbag 13 contacts the side wall of the aluminum alloy window frame 3, the hemispherical airbag 13 is squeezed and deformed, which further buffers the aluminum alloy sliding window 4, ultimately reducing the impact force between the aluminum alloy sliding window 4 and the aluminum alloy window frame 3. At the same time, due to the elastic reaction force of the first spring 8, the friction base plate 7 and the aluminum alloy sliding window 4 have a large friction force. Therefore, the aluminum alloy sliding window 4 will not easily rebound under the elastic reaction force of the second spring 16 and the hemispherical airbag 13.
