An aluminum alloy door and window frame assembly and splicing device

Abstract

This invention provides an assembly and splicing device for aluminum alloy door and window frames, including multiple support rod units. Each support rod unit has a height adjustment mechanism in its middle section, and fixed clamping mechanisms are symmetrically arranged at both ends of each height adjustment mechanism. One side of each fixed clamping mechanism is located at both ends of multiple parallel linkage mechanisms. This invention uses the fixed clamping mechanisms to position, clamp, and suspend the profile outside the window, and then assembles and splices the frame outside the window. This avoids the process of moving a large and heavy frame from inside the room to outside the window, thus greatly reducing the risks of working at heights. The height adjustment mechanism, in conjunction with the fixed clamping mechanism, allows for more convenient and accurate alignment of the frame with the window opening. By operating the fixed clamping mechanism, the frame is installed in place, saving manpower while ensuring a tighter installation and reducing installation gaps.

Description

Technical Field

[0001] This invention relates to the field of system door and window installation equipment technology, specifically to an assembly and splicing device for aluminum alloy door and window frames. Background Technology

[0002] With economic development and the continuous improvement of people's living standards, aluminum alloy structures are being used more and more widely in civil building construction projects, especially aluminum alloy system doors and windows, which have good sound insulation and heat preservation effects, beautiful appearance, and reliable structure.

[0003] However, the installation of aluminum alloy system doors and windows is relatively difficult, and generally there are two main installation methods:

[0004] 1. After the installation personnel have assembled and spliced ​​the aluminum alloy door and window frame indoors, they insert it into the window opening for fixing. The advantage of this installation method is that the installation process is relatively safe and there is no risk of working at height. The disadvantage is that the outer dimensions of the aluminum alloy door and window frame are slightly smaller than the inner dimensions of the window opening. After installation, the gap between the aluminum alloy door and window frame and the window opening is relatively large, which has a negative impact on the sound insulation and heat preservation effect.

[0005] 2. After the installation personnel have assembled the aluminum alloy door and window frames indoors, they first move the frames out of the window opening and then insert them into the opening from the outside to secure them. The advantage of this installation method is that because the outer opening of the window opening is slightly larger than the inner opening, the gap between the aluminum alloy door and window frames and the window opening is small after installation, which has almost no impact on the sound insulation and heat preservation effect. The disadvantage is that the assembled aluminum alloy door and window frames are large in size and heavy in weight, making the movement process more difficult. Moreover, moving such a heavy component outside the window will inevitably increase the operational risk for the installers. Summary of the Invention

The upper part of the height positioning block is provided with a stabilizing adjustment component, the lower part of which is provided with a profile clamping component, and a rack clearance groove is respectively opened at one end of each side of the height positioning block.

[0013] Furthermore, the stabilizing adjustment component includes a sliding stop block, the middle of which is slidably connected to the upper part of the height positioning block, one end of which is slidably connected to the middle part of the stop block positioning screw, one end of which is located on the upper side of the height positioning block, the other end of which is threadedly connected to the stop block positioning nut, and the other end of which is provided with a buffer pad.

The frame is then assembled and spliced ​​outside the window, avoiding the process of moving a large and heavy frame from inside the room to outside the window, thus greatly reducing the risk of working at height. The height adjustment mechanism, in conjunction with the fixed clamping mechanism, makes it easier and more accurate to align the frame with the window opening. The frame is then installed in place by operating the fixed clamping mechanism, saving manpower while making the installation tighter and reducing installation gaps. Attached Figure Description

By rotating the crank 233, the drive worm 232 is driven to rotate, which in turn drives the drive worm wheel 231 and the bevel drive gear 23 to rotate, which in turn drives the two bevel driven gears 24 to rotate, which further drives the two top height adjustment racks 25 and the two ground height adjustment racks 26 to move up and down respectively, thereby driving the two fixed clamping mechanisms 3 to move up and down respectively, so that the stabilizing adjustment components 32 in the two fixed clamping mechanisms 3 are moved outside the window opening size, and the profile clamping components 33 in the two fixed clamping mechanisms 3 are just within the window opening size.

[0036] Please refer to the following examples. Figure 8-9The fixing clamping mechanism 3 includes a height positioning block 31, the middle of which is slidably connected to the middle of the support rod unit 1. A stabilizing adjustment component 32 is provided on the upper part of the height positioning block 31, and a profile clamping component 33 is provided on the lower part of the height positioning block 31. A rack clearance groove 34 is respectively opened at one end of each side of the height positioning block 31. The stabilizing adjustment component 32 includes a sliding stop 321, the middle of which is slidably connected to the upper part of the height positioning block 31. The sliding abutment 321 is slidably connected at one end to the middle of the abutment positioning screw 322. One end of the abutment positioning screw 322 is located on the upper side of the height positioning block 31, and the other end of the abutment positioning screw 322 is threadedly connected to the abutment positioning nut 323. The other end of the sliding abutment 321 is provided with a buffer rubber pad 324.

One end of the clamping telescopic screw 333 is located on the lower side of the height positioning block 31. The other end of the clamping telescopic arm 331 is provided with multiple profile clamping blocks 334. The profile clamping blocks 334 are made of elastic silicone. Through the threaded engagement of the abutment positioning nut 323 and the abutment positioning screw 322, the buffer pad 324 is tightly pressed against the outside of the window opening. On the interior wall, the unassembled top and bottom frame profiles are positioned using multiple profile clamps 334. Then, the vertical frame profiles on both sides are assembled and spliced ​​with the top and bottom frame profiles using connectors. The assembled frame is aligned with the window opening using the height adjustment mechanism 2. Multiple clamping telescopic nuts 332 are rotated, and through the threaded engagement of the multiple clamping telescopic nuts 332 and multiple clamping telescopic screws 333, the clamping telescopic arms 331 are slowly retracted, thereby inserting the assembled frame from outside the window opening into the window opening to complete the fixed installation.

[0037] Please refer to the following examples. Figure 10 The parallel linkage mechanism 4 includes a linkage center block 41. Both sides of the linkage center block 41 are rotatably connected to one end of a plurality of parallel linkage bodies 42. The other ends of the plurality of parallel linkage bodies 42 are rotatably connected to one side of a plurality of linkage fixing blocks 43. The other side of the plurality of linkage fixing blocks 43 is respectively located on one side of a plurality of fixing clamping mechanisms 3. This design is to ensure that the two support rod units always remain parallel.

[0038] Operating principle: First, by loosening the telescopic outer lock 13, the length of the support rod unit 1 can be shortened. The two support rod units 1 are placed at a distance slightly narrower than the width of the window opening. The position of the positioning block 155 is adjusted using the positioning slide bar 154. The verticality of the support rod unit 1 is ensured by observing the universal level bubble 27. The support rod unit 1 is then tightened and fixed by tightening the telescopic outer lock 13. Next, by moving the center slider 21 to the midpoint of the window opening height, the crank handle 233 is turned, causing the drive worm gear 232 to rotate. This, in turn, drives the drive worm wheel 231 and the conical drive gear 23 to rotate, which in turn drives the two conical driven gears 24 to rotate. This further drives the two height adjustment racks 25 and 26 to move up and down, thereby moving the two fixed clamping mechanisms 3 up and down. The stabilizing adjustment component 32 in step 3 is moved outside the window opening size, so that the profile clamping components 33 in the two fixed clamping mechanisms 3 are just within the window opening size; then, through the threaded engagement of the abutment positioning nut 323 and the abutment positioning screw 322, the buffer pad 324 is pressed tightly against the interior wall outside the window opening, and the unassembled upper and lower frame profiles are positioned by multiple profile clamping blocks 334. Then, the vertical frame profiles on both sides are assembled and spliced ​​with the upper and lower frame profiles through connectors. The assembled frame is aligned with the window opening through the height adjustment mechanism 2; finally, the multiple clamping telescopic nuts 332 are rotated respectively, and through the threaded engagement of the multiple clamping telescopic nuts 332 and the multiple clamping telescopic screws 333, the clamping telescopic arm 331 is slowly retracted, thereby inserting the assembled frame from outside the window opening into the window opening, completing the fixed installation.
