Description

Technical Field

[0001] The present invention relates to the field of doors and windows, and particularly to an aluminum alloy window frame connection component and an installation method thereof. Background Art

[0002] In traditional aluminum alloy window frame connection technologies, corner codes are usually used as connecting pieces to fix various parts of the window frame (such as side seals, bottom beams, etc.) together. However, this connection method has several significant limitations:

[0003] Non-adjustable width: Traditional corner code designs often have a fixed width and cannot be adjusted according to the actual width of the aluminum alloy window frame or the installation groove. This results in the need for additional processing or adjustment during installation if the width of the window frame or groove does not match the corner code, increasing the installation difficulty and cost.

[0004] Insufficient stability: When the width of the corner code does not match the width of the groove, the window frame may be prone to shaking or instability after installation, affecting the overall performance and service life of the window.

[0005] Lack of fine-tuning mechanism: Traditional corner codes lack a fine-tuning mechanism and cannot be precisely adjusted during installation to meet the installation requirements of different sizes and shapes.

[0006] Complex installation: Due to the fixed width and lack of flexibility of the corner code, additional tools or methods are often required for positioning and adjustment during installation, increasing the complexity and time cost of installation. Summary of the Invention

[0007] The purpose of the present invention is to provide an aluminum alloy window frame connection component and an installation method thereof to solve the problems raised in the above background art.

[0008] To achieve the above purpose, the present invention provides the following technical solution: An aluminum alloy window frame connection component includes two connecting plug frames which are perpendicularly welded together. A connecting screw rod is screwed on the surface of the connecting plug frame. An additional block is slidably connected inside the connecting plug frame and is fixed in the connecting plug frame by screws. A reserved opening is provided on the surface of the additional block, and a turntable is rotatably connected inside the reserved opening. A traction block is inserted on the surface of the additional block. One end of the traction block is screwed with a threaded rod which is fixed on the surface of the turntable. The other end of the traction block is fixed on the surface of an extended support plate. A scale mark two is provided at one end of the extended support plate, and a scale mark one is provided at one end of the connecting plug frame.

[0009] Preferably, a plastic strip is fixed at the external corner formed after the connection of the two connection plug frames. An isosceles trapezoidal strip is integrally formed on the surface of the connection plug frame. A first screw hole is formed on the surface of the isosceles trapezoidal strip. The connection screw rod is screwed in the first screw hole. A notch is formed at one end of the additional installation block. A rubber cushion block is fixed on the surface of the notch. After the additional installation block is pushed into the connection plug frame, the rubber cushion block is elastically deformed after the connection screw rod is locked and extruded.

[0010] Preferably, two groups of limiting strips are arranged on the inner ring surface of the connection plug frame. The two groups of limiting strips are symmetrically distributed up and down. The limiting strip is in the shape of a concave-shaped strip. A rubber clamping strip is fixed in the groove body of the limiting strip. The thickness of the limiting strip is greater than the height of the groove body of the limiting strip. The additional installation block is slidably connected between the two groups of limiting strips, and the rubber clamping strip clamps between the limiting strip and the additional installation block to generate elastic deformation.

[0011] Preferably, side grooves are formed on both sides of the additional installation block. Connection screws are screwed on the surfaces of the side grooves. One end of the connection screw is screwed on the inner ring surface of the connection plug frame.

[0012] Preferably, through holes are formed on both sides of the additional installation block. The through holes are in the shape of square grooves. The through holes are communicated with the reserved holes. The traction block is movably inserted into the through holes. The length of the long side of the traction block is equal to the depth of the through holes. The traction block is in the shape of a square block. A second screw hole is formed on the surface of the traction block. The second screw hole is in cooperation connection with the threaded rod.

[0013] Preferably, the turntable is in the shape of a H-shaped cylinder. The two ends of the turntable are respectively rotatably connected in two groups of limiting grooves. The limiting grooves are in the shape of arc grooves. The limiting grooves are formed on the side walls of the reserved holes. The diameter of the end plate body of the turntable is greater than the width of the groove opening of the reserved holes. Rubber rings are sleeved and fixed at both ends of the turntable. The rubber rings clamp between the turntable and the limiting grooves to generate elastic deformation.

[0014] Preferably, a dial rod is fixed between two parallel side walls of the turntable. There are multiple dial rods, and the multiple dial rods are arranged and distributed around the rod body of the turntable as the central axis.

[0015] Preferably, the extension support plate is in the shape of a C-shaped plate structure. The two end plate bodies of the extension support plate respectively lean against one side of the two inner ring surfaces of the connection plug frame. Multiple rubber clamping pieces are fixed on the surface of the other plate body of the extension support plate.

[0016] Preferably, embedding grooves are formed on the surfaces of the two end plate bodies of the extension support plate. Elastic bands are fixed inside the embedding grooves. The other ends of the elastic bands are fixed in the embedding grooves of the end plate body of the other extension support plate. After the two extension support plates are pushed into the connection plug frame and the end plate bodies of the two extension support plates lean against each other, the elastic bands are in the initial state, and the traction block retracts into the through holes.

[0017] An installation method for an aluminum alloy window frame connection assembly, including the aluminum alloy window frame connection assembly. The method includes the following steps:

[0018] Insert a connecting plug frame into the end slot of the side seal of the aluminum alloy window frame, insert another connecting plug frame into the end slot of the bottom beam of the aluminum alloy window frame, then pass a connecting screw through the side seal and thread it into the first screw hole of a connecting plug frame, and pass another connecting screw through the bottom beam and thread it into the first screw hole of the other connecting plug frame;

[0019] When the width of the connecting plug frame is less than the width of the slot to be fitted, rotate the turntable to push the traction blocks on both sides to move outward from the connecting plug frame, and calculate whether the distance between the two protruding traction blocks is equal to the width of the slot where the connecting plug frame is to be installed according to the scales on the surface of Scale Marking One and Scale Marking Two. After the widths match, insert the connecting plug frame into the slot to be fitted.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] For the aluminum alloy window frame connection assembly and its installation method proposed by the present invention, through the design of the additional block and the extension support plate, the present invention realizes the adjustability of the width of the connection assembly. When the width of the connecting plug frame is less than the width of the slot to be fitted, the traction blocks on both sides can be pushed by rotating the turntable to make the extension support plate extend outward, thereby increasing the overall width of the connection assembly to adapt to slots of different widths.

[0022] Since the extension support plate can be adjusted according to the width of the slot and ensure that the connecting plug frame fits tightly in the slot, the stability of the window frame after installation is greatly improved, and the occurrence of shaking and instability is reduced.

Detailed implementation manners

[0038] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention 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, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0039] Embodiment 1

[0040] Please refer to Figures 1-3, the present invention provides a technical solution: an aluminum alloy window frame connection assembly, including two connecting plug frames 1, the two connecting plug frames 1 are vertically welded together, a connecting screw rod 4 is screwed on the surface of the connecting plug frame 1, and an additional block 7 is slidably connected inside the connecting plug frame 1. The additional block 7 is fixed in the connecting plug frame 1 by screws. A reserved opening 12 is provided 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, a threaded rod 18 is screwed at one end of the traction block 20, the threaded rod 18 is fixed on the surface of the turntable 15, and the other end of the traction block 20 is fixed on the surface of an extended support plate 21. A second scale mark 26 is provided at one end of the extended support plate 21, and a first scale mark 25 is provided at one end of the connecting plug frame 1.

[0041] Embodiment 2

[0042] Refer to the appendix Figure 4 , on the basis of Embodiment 1, when the additional block 7 is installed in the connecting plug frame 1, it not only satisfies the compensation for the width of the connecting plug frame 1, but also realizes the anti-loosening limit for the connecting screw rod 4. A plastic strip 2 is fixed at the external corner where the two connecting plug frames 1 are connected. An isosceles trapezoidal strip is integrally formed on the surface of the connecting plug frame 1, and a first screw hole 3 is provided on the surface of the isosceles trapezoidal strip. The connecting screw rod 4 is screwed in the first screw hole 3. A notch 8 is provided at one end of the additional block 7, and a rubber cushion block 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 rod 4 is locked and squeezes the rubber cushion block 9 to generate elastic deformation.

[0043] When the connecting plug frame 1 is inserted into the corresponding groove, the connecting screw rod 4 penetrates through the aluminum alloy structure and is screwed in the first screw hole 3. As the connecting screw rod 4 is locked, the connecting screw rod 4 extends into the notch 8 and squeezes the rubber cushion block 9 to generate elastic deformation. The resilience of the rubber cushion block 9 pushes against the connecting screw rod 4, making the connection between the connecting screw rod 4 and the first screw hole 3 firm. That is, after the additional block 7 is installed in the connecting plug frame 1, it provides an elastic cushion for the connecting screw rod 4.

[0044] In order to realize the pre-limitation after the additional block 7 is pushed into the connecting plug frame 1, two groups of limiting strips 5 are provided on the inner ring surface of the connecting plug frame 1. The two groups of limiting strips 5 are symmetrically distributed up and down. The limiting strip 5 is in the shape of a "concave" strip, and a rubber clamping strip 6 is fixed in the groove of the limiting strip 5. The thickness of the limiting strip 5 is greater than the height of the groove of the limiting strip 5. The additional block 7 is slidably connected between the two groups of limiting strips 5, and the rubber clamping strip 6 clamps between the limiting strip 5 and the additional block 7 to generate elastic deformation.

[0045] When the additional block 7 needs to be installed in the connecting plug frame 1, the additional block 7 is pushed flat between the two groups of limiting strips 5. Since the rubber clamping strip 6 clamps between the limiting strip 5 and the additional block 7 to generate elastic deformation, that is, the rubber clamping strip 6 increases the friction between the limiting strip 5 and the additional block 7, so as to prevent 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.

[0046] 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.

[0047] 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.

[0048] Embodiment 3

[0049] See attached Figures 5-14 As shown, on the basis of the second embodiment, in order to adjust the position of the extension support plate 21, the two extension support plates 21 are extended to increase the width from both sides of the connecting plug frame 1, so that the connecting plug frame 1 does not swing after being inserted into the groove body to be matched; both sides of the mounting block 7 are provided with through-holes 13, the through-holes 13 are square grooves, the through-holes 13 are connected with the reserved opening 12, the traction block 20 is movably inserted in the through-holes 13, the long side length of the traction block 20 is equal to the depth of the through-hole 13, the traction block 20 is a square block, and the surface of the traction block 20 is provided with a second screw hole 19, the second screw hole 19 and the threaded rod 18 are connected; the turntable 15 is an "I"-shaped cylinder, and the two ends of the turntable 15 are respectively rotatably connected to the two groups of limit grooves 14, the limit grooves 14 are arc-shaped grooves, and the limit grooves 14 are provided on the side walls of the reserved opening 12, the diameter of the end plate body of the turntable 15 is larger than the slot width of the reserved opening 12, and both ends of the turntable 15 are sleeved with fixed There is a rubber ring 16, which is clamped between the turntable 15 and the limit groove 14 to produce elastic deformation; a lever 17 is fixed between the two parallel side walls of the turntable 15, and a plurality of levers 17 are provided, and the plurality of levers 17 are arranged and distributed with the rod body of the turntable 15 as the central axis; the extension support plate 21 is a "匚"-shaped plate structure, and the two end plates of the extension support plate 21 are respectively leaning against one side of the two inner ring surfaces of the connecting plug frame 1, and a plurality of rubber clips 22 are fixed on the surface of the other plate body of the extension support plate 21; the surfaces of the two end plates of the extension support plate 21 are both provided with an embedding groove 23, and an elastic band 24 is fixed inside the embedding groove 23, and the other end of the elastic band 24 is fixed in the embedding groove 23 of the end plate body of the other extension support plate 21. After the two extension support plates 21 are pushed into the connecting plug frame 1, when the end plate bodies of the two extension support plates 21 are leaning against each other, the elastic band 24 is in the initial state, and the traction block 20 is retracted into the through opening 13.

[0050] 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.

[0051] 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.

[0052] Embodiment 4

[0053] Based on the third embodiment, a method for using an aluminum alloy window frame connection assembly is proposed, comprising the following steps:

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Embodiment 5

[0058] 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:

[0059] 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;

[0060] 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.

[0061] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
