Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy doors and windows, and more specifically to an automatically leveling aluminum alloy door and window stile connection structure and a disassembly and assembly method. Background Art

[0002] The middle mullion is a dividing piece that distinguishes and connects the outer frame. When the window area is very large, the middle mullion is used to divide the outer frame in order to ensure the strength of the outer frame. In addition, the current middle mullion is generally made of aluminum profiles, because aluminum profiles not only have higher strength but also have better quality than profiles of other materials.

[0003] During the installation process, the middle mullion connector is slid into the corresponding slide groove of the aluminum alloy profile frame, leaving a gap between the existing middle mullion connector and the corresponding slide groove of the aluminum alloy profile frame. By rotating the top screw in the middle mullion connector, the top screw is pressed against the bottom surface of the corresponding slide groove of the aluminum alloy profile frame during the process of rotating and descending. The top screw is continuously rotated to make the middle mullion connector slide and rise along the inner wall of the slide groove until the middle mullion connector is pressed against the rail above the slide groove, thereby completing the assembly between the middle mullion connector and the aluminum alloy profile frame.

[0004] However, the installation method of leaving a gap between the middle mullion connector and the corresponding slide groove of the aluminum alloy profile frame causes height differences between the middle mullion connectors at different positions, affecting the subsequent assembly process; at the same time, in the process of the above-mentioned top screw rotating to press the aluminum alloy profile frame and driving the middle mullion connector to rise and press the rail, the top screw will cause pressure damage to the aluminum alloy profile frame, or even deformation, which is not convenient for the subsequent disassembly and assembly of the middle mullion connector; at the same time, the existing middle mullion connector and the mullion in the frame are installed in a sleeve manner and then fixed by tightening bolts, and the disassembly and assembly process is cumbersome. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatically leveling aluminum alloy door and window stile connection structure and disassembly method, which can complete the rapid installation of the stile connector with the frame stile and the aluminum alloy profile frame respectively through the linkage cooperation between the various components, replacing the traditional top screw connection method with a gap and the connection method through tightening bolts, ensuring that the stile connector can maintain precise verticality with the aluminum alloy profile frame after splicing, thereby improving the connection stability of the stile connector.

[0014] A method for disassembling and assembling an automatically leveling aluminum alloy door and window stile connection structure comprises the following steps:

[0015] T1. Slide the middle stile connector into the slide groove on the aluminum alloy profile frame. When the middle stile connector slides to the corresponding installation position on the aluminum alloy profile frame, the insertion hole and the corresponding two halves of the guide groove are coaxially arranged. Under the elastic force of the reset spring, the insertion rod is driven to be inserted into the corresponding insertion hole to complete the positioning and installation of the middle stile connector and the aluminum alloy profile frame.

[0016] T2. Sleeve the middle stile in the frame into the middle stile connector. When the end of the support plate slides downward and contacts the inclined guide plate, the inclined guide plate is squeezed to slide along the corresponding lifting frame in the direction away from the retaining ring. The corresponding squeezing spring is compressed, and the support plate continues to descend. After it is separated from the inclined guide plate, the elastic reset force of the squeezing spring drives the inclined guide plate to slide in the opposite direction and reset. At this time, the inclined guide plate is placed directly above the support plate.

[0017] T3. Slide the fastening part into the through groove until the screw rod slides into the connecting groove and abuts against the end of the screw hole. Rotate the fastening part so that the screw rod rotates and moves forward along the screw hole. When the fastening rod passes through the through groove, the first ball head is squeezed, so that the connecting rod slides down along the fixing ring. The supporting spring is compressed, driving the pressure plate to slide down along the receiving groove, so that the rubber plate is pressed against the inner bottom surface of the slide groove on the aluminum alloy profile frame.

[0018] T4. When the fastening rod passes through the through groove, the second ball head is squeezed synchronously, driving the square column to slide up along the fixed tube, so that the positioning rod slides up and inserts into the two positioning holes set correspondingly on the same axis, completing the limitation of the first positioning plate and the second positioning plate, so that the corresponding lifting frame cannot slide along the corresponding inclined guide groove, completing the assembly of the middle stile connector and the stile in the frame.

[0019] The advantages of the present invention are:

[0020] 1. The present invention slides the first connecting part and the second connecting part that are assembled and fixed together into the corresponding installation position of the aluminum alloy profile frame, and drives the insertion rod to be inserted into the insertion hole under the elastic force of the reset spring, so as to complete the rapid positioning of the middle stile connector and the aluminum alloy profile frame. The middle stile connector is formed by assembling various components, which is convenient for maintenance and replacement. Regular maintenance only requires replacement of damaged components, thereby increasing the overall service life of the middle stile connector.

[0021] 2. The present invention completes the rapid installation of the muntin connector with the frame muntin and the aluminum alloy profile frame respectively through the linkage between the various components, replacing the traditional connection method with a gap (assembly of the muntin connector and the aluminum alloy profile frame) and the connection method by fastening bolts (assembly of the muntin connector and the frame muntin), ensuring that the muntin connector can maintain precise verticality with the aluminum alloy profile frame after splicing, thereby improving the connection stability of the muntin connector; the disassembly and assembly process is simple, and at the same time, the aluminum alloy profile frame is effectively protected from pressure damage and deformation, thereby improving the disassembly efficiency of aluminum alloy doors and windows.

[0057] Working principle of the second embodiment:

[0058] The assembling of the stile connector 1 is completed by inserting the plug plate 28 on the first connecting part 4 into the slot 29 on the second connecting part 5 and by sequentially assembling each group of fastening screws 31 into the corresponding mounting holes 30 .

[0059] The two bases 6 assembled together on the middle stile connector 1 are slid into the slide groove 36 on the aluminum alloy profile frame 3, and the process groove 37 is slidably set on the rail 38 to guide and limit the atrium connector 1. At this time, the insertion rod 9 is pressed against the side of the slide groove 36 and stored in the corresponding two half guide grooves 7. The corresponding reset spring 8 is compressed. When the middle stile connector 1 slides to the corresponding installation position on the aluminum alloy profile frame 3, the socket 39 is coaxially arranged with the corresponding two half guide grooves 7. The elastic force of the spring 8 drives the insertion rod 9 to be inserted into the corresponding insertion hole 39, completing the positioning and installation of the middle wall connector 1 and the aluminum alloy profile frame 3. At this time, the pull rope 70 is in a tensioned state, so that the slider 45 on the side of the corresponding lifting frame 44 is tightened to the bottom of the corresponding inclined guide groove 41, and the elastic force of the extrusion spring 53 drives the inclined guide plate 50 to be pressed against the corresponding retaining ring 49. The first positioning plate 54 is placed directly above the second positioning plate 55, and the positioning holes 56 on the two are coaxially arranged.

[0060] The end of the support plate 46 is provided with an ear rod, and the end of the ear rod is provided with a guide ball head. By sleeved the middle stile 2 in the frame into the middle stile connector 1, the slide rail 27 on the middle stile 2 in the frame slides along the assembled limit groove 25, and the support plate 46 slides along the assembled avoidance groove 26. When the guide ball head at the end of the support plate 46 slides downward and contacts the inclined guide plate 50, the inclined guide plate 50 is squeezed to slide along the corresponding lifting frame 44 in the direction away from the retaining ring 49, and the corresponding squeezing spring 53 is compressed, and the support plate 46 continues to descend. When the guide ball head is separated from the inclined guide plate 50, the elastic restoring force of the extrusion spring 53 drives the inclined guide plate 50 to slide in the opposite direction and reset. At this time, the inclined guide plate 50 is placed directly above the support plate 46, and the bottom of the middle stile 2 in the frame is pressed on the aluminum alloy profile frame 3, which limits the support plate 46. In conjunction with the subsequent positioning rod 66 to limit the first positioning plate 54 and the second positioning plate 55, the middle stile 2 in the frame cannot be lifted or lowered along the middle stile connector 1, thereby completing the assembly of the middle stile connector 1 and the middle stile 2 in the frame.

[0061] Under the elastic force of the connecting spring 67, the mounting plate 62 is pressed against the top of the base 6. At this time, the second ball head 65 slides out of the second semi-column groove 59 spliced ​​together and extends into the through groove 10. Under the elastic force of the supporting spring 20, the connecting rod 17 is driven to slide up along the fixing ring 19 until the pressure plate 18 is pressed against the top of the receiving groove 16. At this time, the first ball head 15 extends into the through groove 10.

[0062] The fastening part 21 is slidably inserted into the through groove 10 until the screw rod 32 is slidably inserted into the connecting groove 11 and abuts against the end of the screw hole 12, and the fastening part 21 is rotated to make the screw rod 32 rotate and move forward along the screw hole 12. When the fastening rod 35 passes through the through groove 10, the first ball head 15 is squeezed, so that the connecting rod 17 slides down along the fixing ring 19, and the supporting spring 20 is compressed, driving the pressing plate 18 to slide down along the receiving groove 16, so that the rubber plate 40 is pressed against the inner bottom surface of the slide groove 36 on the aluminum alloy profile frame 3, further improving the middle wall connection. The connection between the connector 1 and the aluminum alloy profile frame 3 is stable, and at the same time, no pressure loss is caused to the aluminum alloy profile frame 3; when the fastening rod 35 passes through the through groove 10, the second ball head 65 is squeezed synchronously, driving the square column 63 to slide up along the fixed tube 58, so that the positioning rod 66 slides up and is inserted into the two positioning holes 56 set correspondingly coaxially, completing the limiting of the first positioning plate 54 and the second positioning plate 55, so that the corresponding lifting frame 44 cannot slide along the corresponding inclined guide groove 41, completing the assembly of the middle stile connector 1 and the middle stile 2 in the frame.

[0063] In summary, through the linkage between the various components, the middle stile connector 1 can be quickly assembled with the frame middle stile 2 and the aluminum alloy profile frame 3, replacing the traditional connection method by fastening bolts, which is easy to disassemble.

[0064] When disassembly is required, the fastening part 21 is rotated in the opposite direction to be removed from the stile connector 1. Under the elastic restoring force of the connecting spring 67, the positioning rod 66 is driven to slide down and disengage from the corresponding positioning hole 56, thereby releasing the limiting of the first positioning plate 54 and the second positioning plate 55. At the same time, under the elastic restoring force of the supporting spring 20, the pressure plate 18 is driven to slide up and reset, thereby releasing the tight limit on the slide groove 36.

[0065] The middle stile 2 is pulled upward along the middle stile connector 1, driving the support plate 46 to slide up. During the sliding and rising process of the support plate 46, the inclined guide plate 50 is driven to move upward synchronously. The inclined guide plate 50 drives the corresponding lifting frame 44 to slide along the corresponding inclined guide groove 41. During the sliding process of the lifting frame 44 along the inclined guide groove 41, the inclined guide plate 50 is driven to slide along the top of the support plate 46 in the direction away from the corresponding support plate 46. During the movement of the lifting frame 44, the pull rope 70 is used to pull the insertion rod 9 to slide out of the socket 39 and store it in the corresponding semi-guide groove 7. The middle stile connector 1 is slid to make the insertion rod 9 move away from the socket 39, thereby releasing the fixed limit of the middle stile connector 1 and the aluminum alloy profile frame 3.

[0066] As the lifting frame 44 slides along the inclined guide groove 41, it drives the inclined guide plate 50 to slide along the top of the support plate 46 in a direction away from the corresponding support plate 46. After the inclined guide plate 50 is separated from the support plate 46, the middle stile 2 in the frame can be directly removed without obstruction, thereby completing the rapid disassembly of the middle stile connector 1, the middle stile 2 in the frame and the aluminum alloy profile frame 3, thereby improving the disassembly work efficiency.

[0067] A method for disassembling and assembling an automatically leveling aluminum alloy door and window stile connection structure comprises the following steps:

[0068] T1. Slide the middle stile connector 1 into the slide groove 36 on the aluminum alloy profile frame 3. When the middle stile connector 1 slides to the corresponding installation position on the aluminum alloy profile frame 3, the insertion hole 39 and the corresponding two halves of the guide groove 7 are coaxially arranged. Under the elastic force of the reset spring 8, the insertion rod 9 is driven to be inserted into the corresponding insertion hole 39 to complete the positioning and installation of the middle stile connector 1 and the aluminum alloy profile frame 3; at this time, the pull rope 70 is in a tensioned state, the first positioning plate 54 is placed directly above the second positioning plate 55, and the positioning holes 56 on the two are coaxially arranged.

[0069] T2. Sleeve the middle stile 2 in the frame into the middle stile connector 1. When the end of the support plate 46 slides downward and contacts the inclined guide plate 50, the inclined guide plate 50 is squeezed to slide along the corresponding lifting frame 44 in the direction away from the retaining ring 49. The corresponding squeezing spring 53 is compressed, and the support plate 46 continues to descend. After it is separated from the inclined guide plate 50, the elastic restoring force of the squeezing spring 53 drives the inclined guide plate 50 to slide in the opposite direction and reset. At this time, the inclined guide plate 50 is placed directly above the support plate 46.

[0070] T3. Slide the fastening part 21 into the through groove 10 until the screw rod 32 slides into the connecting groove 11 and abuts against the end of the screw hole 12. Rotate the fastening part 21 to make the screw rod 32 rotate and move forward along the screw hole 12. When the fastening rod 35 passes through the through groove 10, it squeezes the first ball head 15, so that the connecting rod 17 slides down along the fixing ring 19. The supporting spring 20 is compressed, driving the pressure plate 18 to slide down along the receiving groove 16, so that the rubber plate 40 is pressed against the inner bottom surface of the slide groove 36 on the aluminum alloy profile frame 3.

[0071] T4. When the fastening rod 35 passes through the through groove 10, the second ball head 65 is squeezed synchronously, driving the square column 63 to slide up along the fixing tube 58, so that the positioning rod 66 slides up and inserts into the two positioning holes 56 set correspondingly coaxially, completing the limiting of the first positioning plate 54 and the second positioning plate 55, so that the corresponding lifting frame 44 cannot slide along the corresponding inclined guide groove 41, completing the assembly of the middle stile connector 1 and the frame stile 2.
