Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window technology, specifically to a mullion connection device for thermally broken aluminum windows. Background Technology

[0002] The mullion in a thermally broken aluminum window is the vertical / horizontal support component that separates the window sashes, affecting the window's structural strength, wind pressure resistance, and opening mechanism. The mullion is the "load-bearing skeleton" of the thermally broken aluminum window frame, with main functions including: Structural support: separating large glass areas or multiple windows, improving overall wind pressure resistance, especially important for high-rise buildings or large window openings where mullion strength needs to be reinforced. Functional zoning: enabling multiple opening combinations of window sashes (such as casement + fixed, left and right sliding, etc.), optimizing ventilation and ease of use. Sealing assistance: working with sealing strips to reduce air infiltration, indirectly improving thermal insulation and soundproofing.

[0003] Ordinary thermal break windows and doors typically use iron sheets for mullions, which are prone to rusting over time, have low strength, poor sealing performance, and are prone to leakage in rainy weather. After the mullion frame is installed, the end face milling gaps are relatively large, affecting the aesthetics. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a mullion connection device for thermally broken aluminum windows, thereby solving the mullion connection problem in thermally broken aluminum windows.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mullion connection device for thermally broken aluminum windows, comprising: Thermal break aluminum alloy frame; One set of sliding grooves is located on both sides of the upper end of the thermally broken aluminum alloy frame. The corner bracket central column is a set, and the bottom sliding assembly is fitted onto a set of sliding grooves; A set of rectangular frames is fixed to the front end of the bottom of a set of corner brackets; Rotate the disc to form a set, with the top and bottom movable clips respectively into a set of rectangular frames; The pins, in a set, are fixed to one end of the rotating disk; The strip plate, as a set, is slidably fitted onto the front end of a set of rectangular frames, and its center is connected to a set of pins; The sliding rod consists of two sets, which are movably inserted at both ends of one set of strip plates; The locking teeth are in two sets and are installed at the front end of the two sets of sliding rods; The limiting teeth are in two sets, and are fixedly installed on both sides of one set of sliding grooves.

[0006] Furthermore, each of the pins has an adjustment handle installed at its front end, which facilitates the rotation of the pins, thereby causing the rotating disk to deflect within the rectangular frame.

[0007] Furthermore, each end of a set of strip plates has a limiting groove corresponding to the sliding rod, and a spring is installed at the bottom of the limiting groove. When the position of the corner bracket column is adjusted, the locking teeth engage and disengage with the limiting teeth, and the locking teeth drive the sliding rod to extend and retract.

[0008] Furthermore, the top and bottom of the two sets of locking teeth are staggered with inclined surfaces corresponding to the limiting teeth. By adjusting the strip plate up and down, it is easy to pull the corner code center column forward or push the corner code center column backward.

[0009] Furthermore, the right side of the thermally broken aluminum alloy frame is connected to a side plate, and a second sliding groove is opened on the side plate. The right corner bracket central column is slidably installed in the second sliding groove by a slider, which plays a guiding role.

[0010] Furthermore, each of the corner bracket columns has screw holes at the top and tightening screws at the bottom of the inner rear end, which facilitates the fixing of the corner bracket columns and the installation of the mullion frame.

[0011] This utility model provides a mullion connection device for thermally broken aluminum windows, which has the following advantages: a set of corner bracket columns are slidably fitted onto the thermally broken aluminum alloy frame. By adjusting the position of the bottom strip plate, a locking mechanism is achieved, facilitating the front and rear adjustment of the corner bracket column position. Then, the corner bracket columns are limited by tightening screws. Finally, the mullion frame is fitted on and locked with screws, and then sealed with glue. This not only increases the strength and sealing performance of the doors and windows but also makes them more aesthetically pleasing. Attached Figure Description

The snap-fit ​​locking structure facilitates the adjustment of the corner bracket central column 3 and allows for initial positioning and fixation of the corner bracket central column 3. Then, the corner bracket central column 3 is positioned by tightening screw 19. Finally, the central mullion frame is installed and locked with screws, and then sealed with glue. This increases the strength and sealing of the door and window, and also makes it more aesthetically pleasing.

[0016] In some embodiments, an adjustment handle 11 is installed at the front end of a set of pins 6 to facilitate the rotation of the pins 6, thereby causing the rotating disk 5 to deflect within the rectangular frame 4.

[0017] In some embodiments, a set of strip plates 7 have limiting grooves 12 at both ends corresponding to the sliding rod 8, and a spring 13 is installed at the bottom of the limiting groove 12, such as... Figure 4As shown, when the position of the corner bracket post 3 is adjusted, the locking tooth 9 drives the sliding rod 8 to extend or retract.

[0018] In some embodiments, the top and bottom of the two sets of locking teeth 9 are staggered with inclined surfaces 14 corresponding to the limiting teeth 10, which facilitates pulling the corner bracket central column 3 forward or pushing the corner bracket central column 3 backward.

[0019] In some embodiments, the right side of the thermally broken aluminum alloy frame 1 is connected to a side plate 15, and a second sliding groove 16 is opened on the side plate 15. The right corner bracket column 3 is slidably installed in the second sliding groove 16 by a slider 17, which plays a guiding role.

[0020] In some embodiments, a set of corner bracket columns 3 have screw fixing holes 18 on their upper ends and tightening screws 19 screwed into their inner rear ends, which facilitates fixing the corner bracket columns 3 and installing the mullion frame. When the tightening screws 19 are fixed, the rectangular frame 4 does not interfere with each other, and the two are staggered.

[0021] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
