Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy door and window frames, in particular to an aluminum alloy door and window bottom frame. Background Art

[0002] Aluminum alloy door and window frames refer to the main frames of aluminum alloy doors and windows. When installing aluminum alloy doors and windows, the aluminum alloy door and window frames are limited to installation. At present, the popular aluminum door frames and door panels on the market have exquisite appearance and are not easy to rust, but the cavity of the thermal insulation parts used is small, which causes the proportion of aluminum in the overall material to be relatively large, which increases the price of aluminum and greatly increases the cost of materials. Aluminum profiles are widely used in buildings because of their advantages of light weight and strong resistance. However, aluminum profiles themselves have defects such as poor sound insulation, poor thermal insulation and seismic resistance, and high cost. In addition, the existing outward-opening window frame profile has a relatively large expansion coefficient, and the doors and windows are prone to cracking after installation. They have poor anti-leakage and corrosion resistance. How can the structure of the aluminum alloy door and window frames be adjusted so that they can be easily installed while having a certain thermal insulation effect, saving the amount of aluminum and reducing the cost of use? Therefore, an aluminum alloy door and window bottom frame is needed to solve the above problems. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an aluminum alloy door and window bottom frame to solve the problem of installation convenience in the prior art.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] A bottom frame of an aluminum alloy door and window comprises a bottom frame, an open-type mounting groove is arranged at the upper end of the bottom frame, a rubber groove is arranged on one side of the mounting groove and the outer side of the bottom frame, a rubber groove is arranged inside the rubber groove and on the inner walls of both sides, the rubber groove is a convex groove, and the inner end is open-type, an auxiliary support plate is arranged inside the bottom frame and connected between the two inner walls of the bottom frame, a limit groove is arranged on the side of the rubber groove away from the bottom frame, and a limit cover is slidably connected to the limit groove.

[0006] To implement the above technical solution, the installation and positioning of the entire bottom frame can be facilitated by setting the installation groove. The setting of the rubber groove can facilitate the installation of the sealing rubber and ensure the sealing stability of the bottom frame during use. The rubber pressure groove is set in a convex shape in the rubber groove, which can provide a limiting effect for the installation of the sealing rubber strip and ensure its stability in use after installation. It is not easy to fall off from the rubber pressure groove. The setting of the limiting groove can facilitate the positioning of the bottom frame and ensure its stability in use. The setting of the limiting cover is convenient for ensuring the sealing effect and support stability of the limiting groove when the limiting groove is not needed.

[0007] In one embodiment of the present invention, two groups of rubber grooves are symmetrically provided between the limiting groove and the bottom frame, and a rubber groove baffle is slidably connected in one group of the rubber grooves.

[0008] To implement the above technical solution, two sets of symmetrically arranged rubber grooves can improve ease of use, and sealing rubber strips can be installed on both sides. For the rubber groove at one end that does not need to be installed with a sealing rubber strip, a rubber groove baffle can be used to separate it to ensure its stability in use.

[0009] In one embodiment of the present invention, a hollow rubber groove partition cavity is provided between the two symmetrically arranged rubber grooves.

[0010] By implementing the above technical solution, the hollow glue groove partition can achieve the heat preservation effect while reducing the usage of aluminum and the use cost.

[0011] In one embodiment of the present invention, a triangular limiting opening is provided on the outer side wall of the limiting groove opening end, and the outer side wall of the limiting groove opening on one side of the limiting opening at the opening end is gradually reduced in height as it moves away from the limiting opening.

[0012] To implement the above technical solution, in order to ensure the stability of the limit cover sliding on the limit groove, a triangular limit opening is provided on the outer wall of the open end of the limit groove, and the height of the outer wall of the limit groove opening on one side of the limit opening is gradually lowered in the direction away from the limit opening, thereby forming an M-shaped clamping structure, which reduces the risk of the limit cover falling off the limit groove and ensures its stability in use.

[0013] In one embodiment of the present invention, the two side walls of the limiting cover are wrapped around the outer wall of the limiting groove, and the inner surfaces of the two side walls of the limiting cover are provided with triangular limiting protrusions, and the limiting protrusions match the size of the limiting opening.

[0014] To implement the above technical solution, in order to better cooperate with the structure of the outer wall of the limiting opening and improve the connection stability between the limiting cover and the limiting groove, a limiting protrusion is provided to cooperate with the limiting opening to clamp the limiting cover.

[0015] In one embodiment of the present invention, a mounting protrusion extending horizontally toward the center of the mounting groove is provided on the inner walls of the two side walls of the mounting groove, a limiting plate is slidably connected to the mounting groove, a limiting hook is provided on the bottom end surface of the limiting plate, and the tip of the limiting hook is arranged below the mounting protrusion.

[0016] To implement the above technical solution, a limit plate is provided to seal the open end of the installation groove. When the installation groove is not needed to work, the supporting stability and thermal insulation effect of the installation groove can be improved, and the use of profiles can be reduced, thereby reducing costs. The setting of the limit hook can limit the displacement of the limit plate, so that it can only slide within the installation groove, reducing the risk of the limit plate falling off.

[0017] As described above, the aluminum alloy door and window bottom frame of the present invention has the following beneficial effects:

[0018] 1. The installation groove can facilitate the installation and positioning of the entire bottom frame. The rubber groove can facilitate the installation of the sealing rubber and ensure the sealing stability of the bottom frame during use.

[0019] 2. The rubber pressing groove is set in a convex shape in the rubber groove, which can provide a limiting effect for the installation of the sealing rubber strip, ensure its stability in use after installation, and prevent it from falling off from the rubber pressing groove.

[0020] 3. The setting of the limit groove can facilitate the positioning of the bottom frame and ensure its stability in use, while the setting of the limit cover is convenient for ensuring the sealing effect and support stability of the limit groove when the limit groove is not needed.

The two groups of symmetrically arranged rubber grooves 3 can improve the convenience of use. Sealing rubber strips can be installed on both sides. For the rubber groove 3 at one end where the sealing rubber strip does not need to be installed, the rubber groove baffle 8 can be used to separate it to ensure its stability in use.

[0028] A hollow rubber groove partition cavity 14 is provided between the two symmetrically arranged groups of rubber grooves 3. The hollow rubber groove partition cavity 14 can achieve heat preservation effect while reducing the usage of aluminum material and reducing the use cost.
