Description

Technical Field

[0001] This utility model relates to the technical field of corner connection structures for aluminum-plastic doors and windows, and in particular to a corner connection structure for aluminum-plastic doors and windows. Background Technology

[0002] Aluminum-plastic composite door and window corner brackets are key structural components used to connect two vertical or inclined profiles in aluminum-plastic composite door and window frames. They usually appear at the corners of window or door frames. The corner connection structure of aluminum-plastic doors and windows typically uses the two right-angled sides of the corner bracket to fit into the inner cavities of the two profiles respectively, and then uses screws to pass through the profile wall and the corner bracket to fix the two together, so that the two profiles form a whole at the corner.

[0003] According to the Chinese patent "Corner Connection Structure for Aluminum-Plastic Doors and Windows" authorized announcement number "CN218092770U", the assembly of two adjacent connecting rods is achieved through the cooperation of connecting blocks, threaded holes, through holes, bolts and reinforcing rods, thereby realizing the installation of aluminum-plastic doors and windows and ensuring the tightness of the connection of aluminum-plastic doors and windows.

[0004] In the aforementioned application, aluminum-plastic doors and windows are frequently subjected to wind impacts, which makes it easy for the vibration force on the aluminum-plastic doors and windows to be transmitted to the bolts, which in turn can easily cause the bolts to loosen in the threaded holes, thereby affecting the tightness of the aluminum-plastic door and window connections. Utility Model Content

[0005] Therefore, it is necessary to provide a connection structure for the corner of aluminum-plastic doors and windows to address the problem that the vibration force received by aluminum-plastic doors and windows can easily be transmitted to the bolts, which can easily cause the bolts to loosen in the threaded holes.

[0006] The system includes: a vertical rod and a horizontal rod. An angle bracket is engaged with the inner wall of the vertical rod, and the surface of the angle bracket is engaged with the inner wall of the horizontal rod. It also includes a reinforcing mechanism, comprising a screw threaded to the inner wall of the vertical rod, a positioning rod slidably connected to the inner wall of the angle bracket, and the surface of the positioning rod engaging with the inner wall of the screw. The inner wall of the screw has a liquid guiding hole, and both sides of the inner wall of the positioning rod have oblique holes. A rubber block is slidably connected to the inner wall of the horizontal rod, and the inner wall of the rubber block has a drainage hole. By engaging the positioning rod within the screw, the screw is initially tightened. By injecting strong adhesive into the liquid guiding hole, oblique hole, and drainage hole, the lateral movement of the positioning rod is stopped, thus ensuring the positioning rod is stably engaged within the screw and locking the screw in place. This achieves a stable connection between the angle bracket, vertical rod, and horizontal rod, preventing loosening at the aluminum-plastic door / window joint due to external impacts, thereby ensuring the stability of the aluminum-plastic door / window joint.

[0007] In one embodiment, anti-slip holes are provided on the inner walls of both the crossbar and the corner bracket. The drain hole is connected to both the anti-slip hole and the drain hole, and the drain hole is connected to the oblique hole. Through the cooperation of the anti-slip hole and the drain hole, the rubber block is locked inside the crossbar, thereby ensuring the stable locking of the screw and guaranteeing that the screw is stably located within the crossbar, corner bracket, and vertical bar, thus ensuring the stability of the aluminum-plastic door and window connection.

[0008] In one embodiment, a rubber ring is fixedly connected to the upper surface of the screw, and the surface of the rubber ring is slidably connected to the inner walls of the crossbar and the corner bracket in sequence. The surface of the positioning rod is engaged with the inner wall of the rubber ring. The rubber ring disperses the vibration force on the screw, ensuring that the screw is stably positioned within the crossbar, corner bracket, and vertical bar.

[0009] In one embodiment, a spring is fixedly connected to one side of the positioning rod, and the other end of the spring is fixedly connected to the inner wall of the corner bracket.

[0010] In one embodiment, a pull rope block is fixedly connected to one side of the positioning rod, and the other end of the pull rope block passes through and extends out of the inner wall of the corner bracket.

[0011] In one embodiment, a silicone ring is fixedly connected to the inner wall of the corner bracket, and the surface of the pull cord block is slidably connected to the inner wall of the silicone ring. The silicone ring seals the connection between the pull cord block and the corner bracket, preventing the risk of leakage of strong adhesive.

[0012] In one embodiment, the inner wall of the liquid guiding hole is recessed in a funnel shape, and the inner top wall of the rubber block abuts against the tip of the screw.

[0013] In one embodiment, the screw's surface is threaded to the inner wall of the corner bracket.

[0014] Beneficial effects 1. By cooperating with the positioning rod, liquid guide hole, oblique hole, rubber block and drain hole, the screw is locked, thereby achieving a stable connection between the corner bracket, vertical bar and horizontal bar, avoiding loosening at the connection of aluminum-plastic doors and windows due to external impact, thus ensuring the stability of the connection of aluminum-plastic doors and windows. 2. By cooperating with the anti-slip holes and drainage holes, the rubber block is locked inside the crossbar, thereby ensuring that the rubber block stably locks the screw and that the screw is stably located inside the crossbar, corner bracket and vertical bar, thus ensuring the stability of the aluminum-plastic door and window connection.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This invention describes the connection structure of the corner of an aluminum-plastic door and window.

[0020] In one embodiment, a connecting structure for an aluminum-plastic door / window corner includes: a vertical rod 100 and a horizontal rod 200. An angle bracket 300 is snapped onto the inner wall of the vertical rod 100, and the surface of the angle bracket 300 is snapped onto the inner wall of the horizontal rod 200. It also includes a reinforcing mechanism 400, which includes a screw 401 threaded onto the inner wall of the vertical rod 100. A positioning rod 402 is slidably connected to the inner wall of the angle bracket 300, and the surface of the positioning rod 402 is snapped onto the inner wall of the screw 401. A liquid guiding hole 405 is provided on the inner wall of the screw 401. Oblique holes 406 are provided on both sides of the inner wall of the positioning rod 402. A rubber block 403 is slidably connected to the inner wall of the horizontal rod 200, and a drain hole 404 is provided on the inner wall of the rubber block 403.

[0021] In this embodiment, when assembling aluminum-plastic doors and windows, one side of the horizontal bar 200 is placed against one side of the vertical bar 100. The surface of the corner bracket 300 is secured within the vertical bar 100 and the horizontal bar 200. An electric wrench is used to thread the screw 401 into the corner bracket 300 and the vertical bar 100, so that the end of the screw 401 abuts against the inner wall of the horizontal bar 200. This loosens the restriction on the positioning rod 402, allowing the positioning rod 402 to move laterally within the corner bracket 300 and be secured within the screw 401. The rubber block 403 is then slid into the horizontal bar 200, so that the bottom end of the rubber block 403 abuts against the horizontal bar 200, and the inner top wall of the rubber block 403 abuts against the top of the screw 401. Use a suitable type of strong adhesive and inject an appropriate amount of strong adhesive into the drain hole 404. The strong adhesive in the drain hole 404 flows into the corner bracket 300 through the guide hole 405 and the oblique hole 406. After a certain amount of strong adhesive is injected into the corner bracket 300, stop pouring strong adhesive into the drain hole 404. After the strong adhesive solidifies, it prevents the positioning rod 402 from moving away from the screw 401, so that the positioning rod 402 is stably stuck in the screw 401. Assemble the other vertical rods 100 and horizontal rods 200 in the same way to form aluminum-plastic doors and windows, thereby improving the overall connection strength of the aluminum-plastic doors and windows and effectively ensuring the overall stability of the aluminum-plastic doors and windows.

[0022] like Figure 3 As shown, anti-slip holes 408 are provided on the inner walls of the crossbar 200 and the corner bracket 300. The drain hole 404 is connected to the anti-slip hole 408 and the guide hole 405 respectively. The guide hole 405 is connected to the inclined hole 406. The inner wall of the guide hole 405 is recessed in the shape of a funnel. The inner top wall of the rubber block 403 abuts against the top of the screw 401. The surface of the screw 401 is threadedly connected to the inner wall of the corner bracket 300.

[0023] In this embodiment, a portion of the strong adhesive flowing in the drain hole 404 flows into the anti-slip hole 408. After the strong adhesive solidifies, it locks the rubber block 403 into the crossbar 200.

[0024] like Figure 3-5As shown, a rubber ring 407 is fixedly connected to the upper surface of the screw 401. The surface of the rubber ring 407 is slidably connected to the inner wall of the crossbar 200 and the corner bracket 300. The surface of the positioning rod 402 is engaged with the inner wall of the rubber ring 407. A spring 409 is fixedly connected to one side of the positioning rod 402. The other end of the spring 409 is fixedly connected to the inner wall of the corner bracket 300. A pull rope block 410 is fixedly connected to one side of the positioning rod 402. The other end of the pull rope block 410 passes through and extends out of the inner wall of the corner bracket 300. A silicone ring 411 is fixedly connected to the inner wall of the corner bracket 300. The surface of the pull rope block 410 is slidably connected to the inner wall of the silicone ring 411.

[0025] In this embodiment, pulling the rope block 410 causes the positioning rod 402 to compress the spring 409. The screw 401 is threaded into the corner bracket 300 and the vertical rod 100, causing the rubber ring 407 to slide into the corner bracket 300. The end of the screw 401 abuts against the horizontal rod 200. Loosening the rope block 410 causes the elastic force of the spring 409 to push the positioning rod 402 to move laterally and lock it into the rubber ring 407 and the screw 401.

[0026] Working principle: Place one side of the horizontal bar 200 against one side of the vertical bar 100. Secure the surface of the angle bracket 300 within the vertical bar 100 and horizontal bar 200. Pull the rope block 410, causing the positioning rod 402 to compress the spring 409. Use an electric wrench to thread the screw 401 into the angle bracket 300 and vertical bar 100. Loosen the rope block 410; the elastic force of the spring 409 pushes the positioning rod 402 laterally, securing it within the rubber ring 407 and screw 401. Slide the rubber block 403 into the horizontal bar 200. Inject an appropriate amount of liquid into the drain hole 404. The strong adhesive flows into the drain hole 404, and some of the strong adhesive flows into the anti-slip hole 408. After the strong adhesive solidifies, it locks the rubber block 403 into the crossbar 200. The strong adhesive in the drain hole 404 flows into the corner bracket 300 through the guide hole 405 and the inclined hole 406. After a certain amount of strong adhesive is injected into the corner bracket 300, the pouring of strong adhesive into the drain hole 404 is stopped. After the strong adhesive solidifies, it prevents the positioning rod 402 from moving away from the screw 401, so that the positioning rod 402 is stably stuck in the screw 401.

[0027] It should be noted that the vertical bar 100, horizontal bar 200, corner bracket 300, screw 401, spring 409, and rope block 410 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
