[0002] In traditional aluminum alloy window frame connection technology, angle brackets are usually used as connectors to fix various parts of the window frame (such as side seals, bottom beams, etc.) together. However, this connection method has several significant limitations: The width is not adjustable: Traditional angle brackets are often designed with a fixed width and cannot be adjusted according to the actual width of the aluminum alloy window frame or installation slot. This results in the need for additional processing or adjustment during installation if the width of the window frame or slot does not match the angle bracket, increasing the difficulty and cost of installation.

[0003] Insufficient stability: When the width of the corner code does not match the width of the slot, the window frame may be prone to shaking or instability after installation, affecting the overall performance and service life of the window.

[0004] Lack of fine-tuning mechanism: Traditional corner brackets lack a fine-tuning mechanism and cannot be precisely adjusted during installation to meet the installation requirements of different sizes and shapes.

[0005] Complex installation: Due to the fixed width and lack of flexibility of the angle code, additional tools or methods are often required for positioning and adjustment during the installation process, which increases the complexity and time cost of installation. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1 See also Figure 1-Figure 3 The present invention provides a technical solution: an aluminum alloy window frame connection assembly, comprising two connecting plug frames 1, the two connecting plug frames 1 are vertically welded together, the surface of the connecting plug frames 1 is screwed with a connecting screw 4, the connecting plug frame 1 is internally slidably connected with an additional block 7, the additional block 7 is fixed in the connecting plug frame 1 by screws, a reserved opening 12 is opened on the surface of the additional block 7, a turntable 15 is rotatably connected inside the reserved opening 12, a traction block 20 is inserted on the surface of the additional block 7, one end of the traction block 20 is screwed with a threaded rod 18, the threaded rod 18 is fixed to the surface of the turntable 15, the other end of the traction block 20 is fixed to the surface of an extension support plate 21, one end of the extension support plate 21 is provided with a scale mark 26, and one end of the connecting plug frame 1 is provided with a scale mark 1 25.

[0022] Embodiment 2 See attached Figure 4On the basis of the first embodiment, when the additional block 7 is installed in the connecting plug frame 1, it not only satisfies the compensation of the width of the connecting plug frame 1, but also realizes the anti-loosening and falling limiting of the connecting screw 4. A plastic strip 2 is fixed at the positive corner after the two connecting plug frames 1 are connected. An isosceles trapezoidal strip is integrally formed on the surface of the connecting plug frame 1. A screw hole 3 is opened on the surface of the isosceles trapezoidal strip. The connecting screw 4 is screwed into the screw hole 3. A notch 8 is opened at one end of the additional block 7. A rubber pad 9 is fixed on the surface of the notch 8. After the additional block 7 is pushed into the connecting plug frame 1, the connecting screw 4 is locked and squeezes the rubber pad 9 to produce elastic deformation.

[0023] After the connecting plug frame 1 is inserted into the corresponding groove body, the connecting screw 4 is passed through the aluminum alloy structure and then screwed into the screw hole 3. As the connecting screw 4 is locked, the connecting screw 4 extends into the missing groove 8 to squeeze the rubber pad 9 to produce elastic deformation. The rebound force of the rubber pad 9 pushes the connecting screw 4, so that the connecting screw 4 and the screw hole 3 are firmly connected. That is, after the additional block 7 is installed in the connecting plug frame 1, an elastic pad is provided for the connecting screw 4.

[0024] In order to achieve pre-limitation after the additional block 7 is pushed into the connecting plug frame 1, two groups of limit strips 5 are provided on the inner ring surface of the connecting plug frame 1. The two groups of limit strips 5 are symmetrically distributed up and down, and the limit strips 5 are "concave" shaped strips. A rubber clamp strip 6 is fixed in the groove body of the limit strip 5. The thickness of the limit strip 5 is greater than the height of the groove body of the limit strip 5. The additional block 7 is slidably connected between the two groups of limit strips 5, and the rubber clamp strip 6 is clamped between the limit strip 5 and the additional block 7 to produce elastic deformation.

[0025] When it is necessary to install the additional block 7 in the connecting plug frame 1, the additional block 7 is pushed flatly between the two sets of limit strips 5. Since the rubber clamp 6 is clamped between the limit strip 5 and the additional block 7, elastic deformation is generated, that is, the rubber clamp 6 increases the friction between the limit strip 5 and the additional block 7, thereby preventing the additional block 7 from slipping out of the connecting plug frame 1 when there is no external force to tension the additional block 7.

[0026] In order to fix the additional block 7 after being inserted into the connecting plug frame 1, side grooves 10 are opened on both sides of the additional block 7. The surface of the side grooves 10 is screwed with connecting screws 11, and one end of the connecting screws 11 is screwed to the inner ring surface of the connecting plug frame 1.

[0027] When the mounting block 7 is inserted into the connecting plug frame 1 and the notch 8 is on one side of the screw hole 3, the connecting screw 11 inside the side groove 10 is screwed until the connecting screw 11 is screwed onto the inner wall of the connecting plug frame 1. At this time, the mounting block 7 is firmly fixed in the connecting plug frame 1.

[0028] Embodiment 3 Refer to the attached Figures 5 to 14As shown in the figure, on the basis of the second embodiment, in order to adjust the position of the extension support plate 21, so that after the two extension support plates 21 extend out, the width is increased from both sides of the connection plug frame 1, to ensure that there is no swinging phenomenon after the connection plug frame 1 is inserted into the slot to be fitted; through holes 13 are formed on both sides of the additional block 7. The through holes 13 are square grooves, and the through holes 13 communicate with the reserved holes 12. The traction block 20 is movably inserted into the through holes 13. The length of the long side of the traction block 20 is equal to the depth of the through holes 13. The traction block 20 is a square block, and a second threaded hole 19 is formed on the surface of the traction block 20. The second threaded hole 19 is in fit connection with the threaded rod 18; the turntable 15 is a "工"-shaped cylinder, and the two ends of the turntable 15 are respectively rotatably connected in two groups of limit grooves 14. The limit grooves 14 are arc-shaped grooves, and the limit grooves 14 are formed on the side wall of the reserved hole 12. The diameter of the end plate of the turntable 15 is larger than the width of the slot opening of the reserved hole 12. Rubber rings 16 are sleeved and fixed at both ends of the turntable 15. The rubber rings 16 are clamped between the turntable 15 and the limit grooves 14 to generate elastic deformation; a lever 17 is fixed between the two parallel side walls of the turntable 15. There are multiple levers 17, and the multiple levers 17 are arranged and distributed around the rod body of the turntable 15; the extension support plate 21 is a "匚"-shaped plate structure. The two end plates of the extension support plate 21 respectively lean against one side of the two inner ring surfaces of the connection plug frame 1. A plurality of rubber clips 22 are fixed on the surface of the other plate of the extension support plate 21; embedding grooves 23 are formed on the surfaces of the two end plates of the extension support plate 21. An elastic band 24 is fixed inside the embedding grooves 23. The other end of the elastic band 24 is fixed in the embedding groove 23 of the end plate of the other extension support plate 21. After the two extension support plates 21 are pushed into the connection plug frame 1, when the end plates of the two extension support plates 21 lean against each other, the elastic band 24 is in an initial state, and the traction block 20 retracts into the through hole 13.

[0029] After the additional block 7 is fixed on the connection plug frame 1, the two extension support plates 21 need to be respectively installed on both sides of the additional block 7. The specific operation is as follows: Align the traction block 20 on the surface of the extension support plate 21 with the through hole 13, and while squeezing the two extension support plates 21 to approach the connection plug frame 1, use a finger to拨动 the lever 17 to drive the turntable 15 to rotate clockwise. When the end of the threaded rod 18 is inserted into the corresponding second threaded hole 19, as the turntable 15 rotates, the threaded rod 18 drives the corresponding traction block 20 to retract into the through hole 13 and move until the extension support plate 21 is completely retracted into the connection plug frame 1. Then, bond and fix the elastic band 24 in the embedding grooves 23 at the end plates of the two extension support plates 21 as needed; the reason for adding the elastic band 24 is to pull the two extension support plates 21 after installation, that is, an elastic traction structure is arranged between the two extension support plates 21, so that the extension support plate 21 pushes the traction block 20 into the through hole 13, that is, the second threaded hole 19 and the threaded rod 18 are firmly connected under the action of the elastic force.

[0030] When the width of the connecting plug frame 1 is smaller than the width of the slot body at the end of the aluminum alloy structure, the turntable 15 is rotated counterclockwise, and the turntable 15 drives the two extension support plates 21 to move to the outside of the connecting plug frame 1. The distance between the two extension support plates 21 can be determined according to the values ​​of the scale mark 1 25 and the scale mark 2 26. When the distance is equal to the width of the slot body at the end of the aluminum alloy, the connecting plug frame 1 can be inserted into the corresponding slot body. Since a rubber ring 16 is clamped between the turntable 15 and the limiting groove 14, the rubber ring 16 generates friction to prevent the turntable 15 from rotating at will.

[0031] Embodiment 4 Based on the third embodiment, a method for using an aluminum alloy window frame connection assembly is proposed, comprising the following steps: Step 1: After the connecting plug frame 1 is inserted into the corresponding slot body, the connecting screw 4 is passed through the aluminum alloy structure and then screwed into the screw hole 3. As the connecting screw 4 is locked, the connecting screw 4 extends into the slot 8 to squeeze the rubber pad 9 to produce elastic deformation. The resilience of the rubber pad 9 pushes the connecting screw 4, so that the connecting screw 4 and the screw hole 3 are firmly connected. That is, after the additional block 7 is installed in the connecting plug frame 1, an elastic pad is provided for the connecting screw 4. When it is necessary to install the additional block 7 in the connecting plug frame 1, push the additional block 7 flatly into the two sets of limit The rubber clamping strip 6 is clamped between the limit strip 5 and the additional block 7 to produce elastic deformation, that is, the rubber clamping strip 6 increases the friction between the limit strip 5 and the additional block 7, thereby preventing the additional block 7 from sliding out of the connecting plug frame 1 when there is no external force to tension the additional block 7; when the additional block 7 is inserted into the connecting plug frame 1 and the missing groove 8 is on one side of the screw hole 3, the connecting screw 11 inside the side groove 10 is screwed until the connecting screw 11 is screwed on the inner wall of the connecting plug frame 1, and the additional block 7 is firmly fixed in the connecting plug frame 1.

[0032] Step 2: After the mounting block 7 is fixed to the connecting plug frame 1, the two extension support plates 21 need to be installed on both sides of the mounting block 7 respectively. The specific operation is to align the traction block 20 on the surface of the extension support plate 21 with the through-hole 13, and squeeze the two extension support plates 21 to approach the connecting plug frame 1, while the finger moves the lever 17 to drive the turntable 15 to rotate clockwise. When the end of the threaded rod 18 is inserted into the corresponding screw hole 29, as the turntable 15 rotates, the threaded rod 18 drives the corresponding traction block 20 to retract and move in the through-hole 13 until the extension support plate 21 is completely retracted into the connecting plug frame 1, and the elastic band 24 can be glued and fixed in the embedding groove 23 of the plate body at the end of the two extension support plates 21 as needed; the reason for installing the elastic band 24 is to pull the two extension support plates 21 after installation, that is, an elastic traction structure is set between the two extension support plates 21, so that the extension support plate 21 pushes the traction block 20 to the through-hole 13, that is, the screw hole 29 and the threaded rod 18 are firmly connected under the action of elastic force.

[0033] Step three: When the width of the connecting plug frame 1 is smaller than the width of the slot at the end of the aluminum alloy structure, rotate the turntable 15 counterclockwise, and the turntable 15 drives the two extension support plates 21 to move toward the outside of the connecting plug frame 1. The distance between the two extension support plates 21 can be determined according to the values ​​of scale mark 1 25 and scale mark 2 26. When the distance is equal to the width of the slot at the end of the aluminum alloy, the connecting plug frame 1 can be inserted into the corresponding slot. Since a rubber ring 16 is clamped between the turntable 15 and the limit groove 14, the rubber ring 16 generates friction to prevent the turntable 15 from rotating at will.

[0034] Embodiment 5 Based on the fourth embodiment, a method for installing an aluminum alloy window frame connection assembly is proposed, including an aluminum alloy window frame connection assembly, and the method includes the following steps: Insert one connecting plug frame 1 into the groove body at the end of the edge seal of the aluminum alloy window frame, insert another connecting plug frame 1 into the groove body at the end of the bottom beam of the aluminum alloy window frame, then penetrate a connecting screw 4 through the edge seal and screw it into a screw hole 3 of one connecting plug frame 1, penetrate another connecting screw 4 through the bottom beam and screw it into a screw hole 3 of another connecting plug frame 1; When the width of the connecting plug frame 1 is smaller than the width of the slot body to be matched, the turntable 15 is rotated to push the traction blocks 20 on both sides to move to the outside of the connecting plug frame 1, and according to the scales on the surface of the scale mark 1 25 and the scale mark 2 26, it is calculated whether the distance between the two extended traction blocks 20 is equal to the width of the slot body to be installed in the connecting plug frame 1. After the widths match, the connecting plug frame 1 can be inserted into the slot body to be matched.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
