Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy door and window frames, and in particular to wind-pressure resistant aluminum alloy door and window frames with sealing strips. Background Technology

[0002] Wind-resistant aluminum alloy door and window frames are door and window systems specifically designed to withstand strong wind loads, and are especially important in high-rise buildings, coastal areas, or areas with high wind pressure.

[0003] Wind-pressure resistant aluminum alloy door and window frames require the installation of sealing strips during use. Traditionally, these strips are simply glued to the frame using adhesive. This method results in poor stability; after prolonged use, the ends tend to warp, creating gaps that allow for air exchange between the interior and exterior, reducing insulation effectiveness. Therefore, a wind-pressure resistant aluminum alloy door and window frame with a stable sealing strip installation is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wind-pressure resistant aluminum alloy door and window frame with a sealing strip.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wind-pressure resistant aluminum alloy door and window frame with sealing strips includes a frame on which multiple sealing strips are glued. Multiple pressure plates are movably disposed at both ends of the sealing strips, and the pressure plates press against the outer side of the sealing strips. A fixing seat is fixedly disposed on the frame below the pressure plates. Each fixing seat has an inner cavity. Threaded posts are installed on each pressure plate. A base plate is fixedly disposed at the bottom of each threaded post, and the base plate is movable within the inner cavity.

[0007] In addition, in a preferred configuration, multiple guide members are fixedly provided on each of the pressure plates, and guide grooves are adapted to be provided on the frame corresponding to the guide members.

[0008] In addition, a preferred structure is that each of the pressure plates is provided with a threaded cavity, and the threaded post is adapted to be located in the threaded cavity for meshing and rotation.

[0009] In addition, a preferred structure is that each threaded post has a screw head fixedly provided at its top and a base plate fixedly provided at its bottom.

[0010] In addition, a preferred structure is that the top of each fixing seat is provided with a through cavity, and the through cavity is connected to the inner cavity.

[0011] Furthermore, in a preferred configuration, the width of the through cavity is greater than the diameter of the threaded post, and the width of the through cavity is less than the diameter of the base plate.

[0012] The beneficial effects of this utility model are as follows: the sealing strip is initially assembled on the frame by adhesive backing, and by adjusting the threaded post, the pressure plate can be fixed and locked on the outside of the sealing strip to prevent the end of the sealing strip from lifting up during long-term use, thereby improving the stability of the sealing strip after installation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5 A wind-pressure resistant aluminum alloy door and window frame with sealing strips includes a frame 1. Multiple sealing strips 2 are glued to the frame 1. Multiple pressure plates 3 are movably mounted at both ends of each sealing strip 2, and the pressure plates 3 press against the outer side of each sealing strip 2. A fixing seat 4 is fixedly mounted on the frame 1 below each pressure plate 3. Each fixing seat 4 has an inner cavity 42. Threaded posts 51 are mounted on each pressure plate 3. A base plate 52 is fixedly mounted at the bottom of each threaded post 51, and the base plate 52 is movable within the inner cavity 42.

[0021] Each pressure plate 3 is fixedly equipped with multiple guide members 31, and each guide member 31 on the frame 1 is fitted with a guide groove 11. The fit between the guide members 31 and the guide groove 11 can improve the stability of the pressure plate 3 during movement.

[0022] Each pressure plate 3 has a threaded cavity 32, and the threaded post 51 is adapted to mesh and rotate within the threaded cavity 32. A threaded damping self-locking structure, which is a prior art technique, is provided between the threaded post 51 and the threaded cavity 32 to ensure the stability of the threaded post 51 within the threaded cavity 32. This is prior art and is not a major technical problem to be solved in this technical solution, so it will not be described in detail in this utility model.

[0023] Each threaded post 51 has a screw head 5 fixedly installed at its top and a base plate 52 fixedly installed at its bottom.

[0024] Each of the fixed bases 4 has a through cavity 41 on its top, and the through cavity 41 is connected to the inner cavity 42. The width of the through cavity 41 is greater than the diameter of the threaded post 51, and the width of the through cavity 41 is less than the diameter of the base plate 52.

[0025] In this embodiment, the frame 1 is a wind-pressure resistant aluminum alloy door and window frame in the prior art, and the sealing strip 2 is installed on the frame 1 by adhesive backing. These are all prior art and are not the main technical problems to be solved in this technical solution, so they will not be described in detail in this utility model.

[0026] Furthermore, when the user needs to install the sealing strip 2, simply install the sealing strip 2 on the frame 1 using adhesive backing, ensuring that both ends of the sealing strip 2 are within the pressing range of the pressure plate 3.

[0027] After the sealing strip 2 is glued and installed, simply move the pressure plate 3 to the outside of the sealing strip 2 via the guide 31, and then tighten the screw head 5 with a screwdriver to drive the threaded post 51 to rotate upward. During the movement of the threaded post 51, the base plate 52 also moves synchronously, and during the rotation of the threaded post 51, the base plate 52 also rotates synchronously upward.

[0028] When the base plate 52 contacts the top wall of the inner cavity 42, since the base plate 52 cannot pass through the through cavity 41, it will be stuck on the top wall of the inner cavity 42. Subsequently, the pressure plate 3 will also move downward by the rotation of the threaded column 51. This fixes the pressure plate 3, thereby locking it to the outside of the sealing strip 2, thus preventing the sealing strip 2 from lifting.

[0029] Furthermore, anti-slip pads are laid on the contact surfaces of the top wall of the inner cavity 42 and the bottom plate 52 to ensure the stability of the engagement between the inner cavity 42 and the bottom plate 52.

[0030] Furthermore, when the user needs to remove the sealing strip 2, simply use a screwdriver to turn the screw head 5 in the opposite direction to rotate the threaded post 51 downwards. At the same time, the base plate 52 also rotates downwards simultaneously. This releases the pressure plate 3 from the sealing strip 2, allowing the sealing strip 2 to be removed.

[0031] Furthermore, the pressure plate 3 and the fixing seat 4 in this application can be pre-installed anywhere during the design phase, according to the design requirements of the frame 1, to ensure their compatibility with the sealing strip 2. Additionally, space is reserved on the frame 1 corresponding to the pressure plate 3 and the fixing seat 4 to ensure that they do not affect the normal use of the frame 1.

[0032] In this utility model, the sealing strip 2 is initially assembled onto the frame 1 by adhesive backing. By adjusting the threaded post 51, the pressure plate 3 can be fixed and locked to the outside of the sealing strip 2 to prevent the end of the sealing strip 2 from lifting up during long-term use, thereby improving the stability of the sealing strip 2 after installation.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
