[0001] The invention relates to the technical field of aluminum alloy windows, in particular to a novel heat-insulating broken-bridge aluminum alloy window. Background Art

[0002] The thermal insulation aluminum alloy window is made by inserting a thermal insulation strip in the middle of the aluminum profile, breaking the aluminum profile to form a thermal bridge, and then making the door and window frames and sashes, and finally assembling hollow glass, hardware, glass glue and sealing strips. Due to the addition of thermal insulation strips in the aluminum profile, the thermal insulation performance of the thermal insulation aluminum alloy window is significantly better than that of traditional aluminum alloy windows.

In summary, how to ensure the overall strength of the aluminum profile and the stability of the connection between two adjacent aluminum profiles when the width of the heat-insulating strip increases and the overall thickness of the aluminum alloy window does not increase is a problem that needs to be solved urgently.

[0032] Embodiment 1

[0033] As Figure 2 and Figure 3 shown, this embodiment provides a new type of heat-insulating broken-bridge aluminum alloy window, including a frame and sash composed of four frames. Each frame includes two independent aluminum profiles 1. The aluminum profile 1 is an isosceles trapezoid, and the included angle between the end face of the aluminum profile 1 and its edge is 45°; a heat insulation strip 2 is arranged between the two aluminum profiles 1. A plug-in socket 3 for plugging the heat insulation strip 2 is fixedly arranged on the surface of the aluminum profile 1. The plug-in socket 3 can be welded to the aluminum profile 1 or integrally formed with the aluminum profile 1; the heat insulation strip 2 is made of a hard material and the heat insulation strip 2 is in close fit with the plug-in socket 3. The two aluminum profiles 1 are fixedly connected together through the cooperation of the heat insulation strip 2 and the plug-in socket 3; the edges and end faces of the two fixedly connected aluminum profiles 1 are in a flush state; it should be noted that in this embodiment, the plug-in socket 3 is used to replace Figure 1 the hollow bracket in the prior art shown in

[0034] As Figure 2 and Figure 3As shown, a reinforcing rib 4 is fixedly arranged on the surface of the aluminum profile 1, and a positioning groove 401 is formed in the reinforcing rib 4; a connector 5 is arranged between two adjacent frames, and the connector 5 includes a positioning block 501 that cooperates with the positioning groove 401; since the plug-in socket 3 is used to replace the hollow bracket in the prior art in this embodiment, the overall strength of the aluminum profile 1 will be affected, so an additional reinforcing rib 4 is added to improve the overall strength of the aluminum profile 1; the reinforcing rib 4 can be welded to the aluminum profile 1 or integrally formed with the aluminum profile 1; in the prior art, the end faces of two adjacent frames are attached together, and a connecting angle code is arranged between the two frames, and the connecting angle code is respectively inserted into the hollow brackets of the two frames to fix the two frames; in this embodiment, the adjacent two frames are fixed through the cooperation of the connector 5 and the positioning groove 401, and the entire frame and sash are composed of four frames, and connectors 5 are arranged between two adjacent frames, so the total number of connectors 5 is four; after the positioning block 501 enters the positioning groove 401, the aluminum profile 1 cannot move relative to the connector 5, so as long as the positioning grooves 401 on two adjacent frames are all in a cooperating state with the positioning blocks 501, it can be ensured that the two adjacent frames will not move relative to each other, and the entire frame and sash can remain in an integral state.

[0035] In this embodiment, the connector 5 includes two independent mounting seats 502, the number of positioning blocks 501 in the connector 5 is two, and the positioning blocks 501 are respectively movably connected to the corresponding mounting seats 502; a limiting strip 6 that cooperates with the mounting seat 502 is fixedly installed on the surface of the aluminum profile 1, and the limiting strip 6 is parallel to the reinforcing rib 4; the two independent mounting seats 502 can be fixedly connected through existing fasteners such as bolts, and the cooperation mode between the positioning block 501 and the mounting seat 502 includes but is not limited to rotational connection and sliding connection; during the process of manually inserting the mounting seat 502 between the two aluminum profiles 1 of the frame, the limiting strip 6 abuts against the mounting seat 502 and plays a guiding and limiting role on the mounting seat 502 until the positioning block 501 enters the positioning groove 401; in this state, the mounting seat 502 cannot be inserted between the two aluminum profiles 1 any further, and the cooperation between the limiting strip 6 and the reinforcing rib 4 also plays a limiting role on the mounting seat 502 to prevent the connector 5 from separating from the aluminum profile 1 in a direction perpendicular to the limiting strip 6 and the reinforcing rib 4.

[0036] As Figure 4 and Figure 6As shown, a receiving cavity 503 is provided on the mounting base 502. A plurality of guide rods 504 are fixedly installed in the receiving cavity 503. A moving plate 505 is slidably installed on the plurality of guide rods 504 together. The positioning block 501 is fixedly installed on the moving plate 505. The positioning block 501 can drive the moving plate 505 to enter the receiving cavity 503 along the guide rods 504 under the drive of an external force. The moving plate 505 can also drive the positioning block 501 to move out of the receiving cavity 503 under the drive of an external force. A support spring 506 is connected between the moving plate 505 and the mounting base 502. A retaining piece 507 for preventing the moving plate 505 from falling off the receiving cavity 503 is installed on the mounting base 502. The support spring 506 is always in a compressed state and applies a thrust force to the moving plate 505. The retaining piece 507 acts to block the moving plate 505 to prevent the moving plate 505 from falling off the receiving cavity 503. When the positioning block 501 drives the moving plate 505 to enter the receiving cavity 503 under the drive of an external force, the support spring 506 is further compressed. When the external force acting on the positioning block 501 is removed, the support spring 506 resets and elongates, and pushes the moving plate 505 to drive the positioning block 501 to reset synchronously until the moving plate 505 fits against the retaining piece 507, and the positioning block 501 also moves out of the receiving cavity 503 synchronously.

[0037] In this embodiment, the end face of the reinforcing rib 4 is an arc surface, and the cross-section of the positioning block 501 is a sector, so that when the mounting base 502 is inserted between the reinforcing rib 4 and the limiting strip 6 along the direction of the reinforcing rib 4, the positioning block 501 can be pushed by the end face of the reinforcing rib 4 to enter the receiving cavity 503.

[0038] The two independent mounting bases 502 have a first state of being separated from each other and a second state of being fitted together. In the second state, the two independent mounting bases 502 can be fixedly connected together; Figures 2 - 6 All the figures shown are in the second state of the mounting base 502.

[0039] Specifically, the steps for an operator to assemble two adjacent frames are as follows: First, insert the heat insulation strip 2 into the corresponding two socket connectors 3 so that the corresponding two aluminum profiles 1 are connected together and kept in a parallel state. Then, manually adjust the positions of the corresponding two aluminum profiles so that the end faces of the corresponding two aluminum profiles are flush. In this way, the two frames are each assembled. Manually hold one mounting seat 502 and insert it into the interior of one frame along the direction of the limiting strip 6 in the frame, that is, insert it between the corresponding two aluminum profiles 1. During the insertion process, the mounting seat 502 always fits against the limiting strip 6, and the limiting strip 6 plays a role in guiding and limiting the movement of the mounting seat 502. During the insertion process, the positioning block 501 abuts against the reinforcing rib 4 and is pushed into the receiving cavity 503 under the reaction force of the reinforcing rib 4. When the positioning block 501 enters the receiving cavity 503, it drives the moving plate 505 to move synchronously. The moving plate 505 separates from the retaining piece 507 and further compresses the support spring 506 to store energy. As the mounting seat 502 continuously penetrates between the two aluminum profiles 1, the positioning block 501 finally reaches the position corresponding to the positioning groove 401. At this time, the reinforcing rib 4 no longer exerts a squeezing effect on the positioning block 501, and the support spring 506 will elongate and reset. The moving plate 505 and the positioning block 501 also tend to reset synchronously until the moving plate 505 fits against the retaining piece 507, and the positioning block 501 is synchronously snapped into the positioning groove 401. In this state, the mounting seat 502 is stuck between the two aluminum profiles 1, that is, the assembly of one mounting seat 502 and a single frame is completed. Complete the assembly of the other mounting seat 502 and the other frame according to the above steps. Finally, manually adjust the positions of the two frames so that the mounting seats 502 respectively installed on the two frames are in a second state of fitting, and fix and connect the two mounting seats 502 with fasteners.

[0040] In this field, the fasteners used to fix the two mounting seats 502 are usually bolts. However, it is found in actual use that when the window experiences long-term transportation or long-term wind force after installation, the bolts will become loose due to long-term vibration, affecting the overall stability of the window. And in some usage environments, rainwater will penetrate into the contact position between the bolts and the mounting seat 502. After the rainwater evaporates, stains will remain at the contact position between the bolts and the mounting seat 502, resulting in corrosion of the bolts, which causes great inconvenience to the maintenance and disassembly of the window in the later stage.

[0041] Such as Figure 6As shown, in the present embodiment, an arc-shaped plug plate 508 is movably mounted on a mounting seat 502 in each connector 5, and the parts of the two mounting seats 502 that fit together in the second state are provided with an arc-shaped slot that penetrates the mounting seat 502 and cooperates with the arc-shaped plug plate 508; in the present embodiment, after the mounting seats 502 mounted on the two frame frames are manually adjusted to the second fit state, the position of the arc-shaped plug plate 508 is adjusted so that the arc-shaped plug plate 508 is inserted into the two arc-shaped slots, thereby fixing the two mounting seats 502 together through the arc-shaped plug plate 508.

[0042] It should be noted that after the arc-shaped plug plate 508 passes through the two mounting seats 502, if the two mounting seats 502 want to move relative to each other, they can only rotate in the direction of the extended arc of the arc-shaped plug plate 508. Since the mounting seats 502 and the aluminum profile 1 are connected together, the rotation of the mounting seats 502 will inevitably drive the aluminum profile 1 to rotate. After installation, the end faces of the two adjacent frames are in contact, that is, the two aluminum profiles 1 cannot rotate relative to each other. Therefore, the arc-shaped plug plate 508 can play a role in fixing and connecting the two mounting seats 502. In addition, even if the window is subjected to external vibration during transportation or later use, The arc plug plate 508 is affected by the dynamic movement, causing it to move relative to the mounting seat 502. As long as the arc plug plate 508 does not separate from the mounting seat 502, it can fix the two mounting seats 502, which greatly increases the earthquake resistance of the window. Furthermore, the arc plug plate 508 is caused to move in a small range through external vibration, which is conducive to draining rainwater that has penetrated into the gap between the contact surface of the arc plug plate 508 and the mounting seat 502. The friction force generated during the small-range movement of the arc plug plate 508 is conducive to cleaning the stains on the contact surface, preventing the arc plug plate 508 from being stuck on the mounting seat 502 due to rust.

[0043] In summary, in this embodiment, the arc-shaped plug plate 508 is used to fix the two mounting seats 502, which can not only ensure a stable connection between the two mounting seats 502, but also improve the shockproof performance of the window, and prevent the arc-shaped plug plate 508 from getting stuck due to rust.

[0044] like Figure 4 As shown, in this embodiment, an arc-shaped rack 509 is fixedly mounted on the arc-shaped plug plate 508, and an adjusting shaft 510 is rotatably mounted on the mounting seat 502 on which the arc-shaped plug plate 508 is mounted through a supporting bracket, and an adjusting knob and an adjusting gear 511 meshing with the arc-shaped rack 509 are fixedly mounted on the adjusting shaft 510; the adjusting knob can be manually turned to control the rotation of the adjusting shaft 510 and the adjusting gear 511, thereby adjusting the position of the arc-shaped rack and the arc-shaped plug plate 508, so that the arc-shaped plug plate 508 can be adjusted to a state of penetrating two arc-shaped plug plates 508 during installation.

[0045] Example 2

[0046] like Figure 8 As shown, on the basis of the above embodiment, in this embodiment, a sliding rod 512 that penetrates the mounting seat 502 is slidably mounted on the mounting seat 502 on which the arc-shaped plug plate 508 is mounted, one end of the sliding rod 512 is fixedly connected to the corresponding movable plate 505, and the other end of the sliding rod 512 is fixedly mounted with a telescopic sleeve 513 that plays a transmission role; the telescopic end of the telescopic sleeve 513 is rotatably connected to the arc-shaped plug plate 508 through a ball hinge; when the movable plate 505 moves in the accommodating cavity 503 along the guide rod 504, the sliding rod 512 will move synchronously with the movable plate 505, and when the sliding rod 512 moves, it will drive the telescopic sleeve 513 to move synchronously Since the telescopic section of the telescopic sleeve 513 is rotatably connected to the arc-shaped plug plate 508 through a ball hinge, the telescopic sleeve 513 will drive the arc-shaped plug plate 508 to move when it moves, and the telescopic sleeve 513 itself will be telescoped; similarly, when the arc-shaped plug plate 508 moves, it will in turn drive the telescopic sleeve 513, the sliding rod 512 and the moving plate 505 to move synchronously, thereby driving the positioning block 501 to move synchronously; in the process of disassembling the frame and sash, the operator only needs to turn the adjusting knob to synchronously control the separation of the arc-shaped plug plate 508 and the mounting seat 502, as well as the separation of the positioning block 501 and the reinforcing rib 4, thereby improving the convenience of operation.

[0047] It should be noted that if the window is subjected to external vibration, even if the positioning block 501 moves relative to the reinforcing rib 4 and the arc-shaped plug plate 508 moves relative to the mounting seat 502, as long as the positioning block 501 does not separate from the positioning groove 401 and the arc-shaped plug plate 508 does not separate from the mounting seat 502, it will not affect the overall stability of the window; the support of the supporting spring 506 on the movable plate 505 prevents the positioning block 501 from separating from the positioning groove 401, thereby also preventing the arc-shaped plug plate 508 from separating from the mounting seat 502.

[0048] like Figure 8 As shown, a plurality of strip grooves 514 are formed on the surface of the arc-shaped plug plate 508 near the end thereof away from the telescopic sleeve 513. When the arc-shaped plug plate 508 and the mounting seat 502 slide relative to each other; when the window is subjected to external vibration, the arc-shaped plug plate 508 will vibrate synchronously and move in a small range along its motion path. During the movement of the arc-shaped plug plate 508, friction is generated between the arc-shaped plug plate 508 and the mounting seat 502. The strip grooves 514 can increase the friction, thereby scraping and cleaning the surface where the mounting seat 502 and the arc-shaped plug plate 508 are in contact.

[0049] like Figure 8 , Figure 9 and Figure 10As shown, a round pin 515 is fixedly installed on the sliding rod 512. An elastic telescopic rod 516 is rotatably installed on the mounting base 502 with the arc-shaped insertion plate 508 through a bracket. A collar 517 sleeved on the round pin 515 and rotatably matched with the round pin 515 is fixedly installed at the end of the telescopic section of the elastic telescopic rod 516. The elastic telescopic rod 516 has a first positioning state and a second positioning state: when the elastic telescopic rod 516 is in the first positioning state, the positioning block 501 is located outside the receiving cavity 503; when the elastic telescopic rod 516 is in the second positioning state, the positioning block 501 is located inside the receiving cavity 503. The elastic telescopic rod 516 is in a normal length that is neither compressed nor stretched in the above two states, and the elastic telescopic rod 516 positions the position of the sliding rod 512 relative to the mounting base 502 by virtue of its own elastic supporting force in the above two states.

[0050] When the window is integrally installed, the elastic telescopic rod 516 is in Figure 8 and Figure 9 the first positioning state shown. In this state, for an external force to drive the positioning block 501 out of the positioning groove 401, it is necessary to overcome not only the supporting force of the supporting spring 506 but also the supporting force of the elastic telescopic rod 516. And the force required to overcome the rotation of the elastic telescopic rod 516 from the first positioning state to Figure 10 the second positioning state shown is very large, and the direction of the force changes continuously. Obviously, even a large external vibration cannot achieve this process. Therefore, the seismic stability performance of the whole window is significantly improved during transportation and later use.

[0051] When disassembling, maintaining and servicing the window, by manually rotating the adjustment knob, the arc-shaped insertion plate 508 is separated from the mounting base 502. At the same time, the arc-shaped insertion plate 508 drives the sliding rod 512 to move through the telescopic sleeve 513, so that the positioning block 501 is separated from the positioning groove 401. In this process, by providing power with the human hand, the elastic telescopic rod 516 rotates from the first positioning state to Figure 10The second positioning state shown, and the positioning block 501 is held at a position disengaged from the positioning slot 401, i.e., located within the receiving cavity 503, so as to facilitate pulling out the mounting seat 502 from the area between the two aluminum profiles 1 (conventionally, manually with the aid of tools to overcome the acting force of the support spring 506 and push the positioning block 501 into the receiving cavity 503, and then pulling out the mounting seat 502, which requires two hands to operate simultaneously and is rather inconvenient); it should be noted that when the elastic telescopic rod 516 is in the second positioning state, the support spring 506 is in a further compressed state, which will exert a thrust on the moving plate 505 and cause the elastic telescopic rod 516 to tend to return to the first positioning state. However, the acting force of the support spring 506 is not sufficient to provide the acting force required for the elastic telescopic rod 516 to reset. Therefore, the positioning block 501 will remain in the state located within the receiving cavity 503. Only after the window is disassembled can the elastic telescopic rod 516 be reset by manually rotating the adjustment knob in the reverse direction, that is, adjusting the positioning block 501 to the initial position where it moves out of the receiving cavity 503.

[0052] In summary, in this embodiment, by adding the elastic telescopic rod 516, on the one hand, the seismic stability of the window is improved, and on the other hand, the convenience of separating the mounting seat 502 from the aluminum profile 1 during window disassembly and maintenance is also improved.

[0053] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
