Description

Technical Field

[0001] This utility model relates to the technical field of reinforced structures for PVC doors and windows, specifically a corner reinforcement structure for PVC doors and windows. Background Technology

[0002] As a common building material, PVC windows and doors are widely used in residential, commercial, and public facilities. PVC windows and doors are made primarily from polyvinyl chloride resin, with the addition of stabilizers, colorants, fillers, and UV absorbers. They are manufactured through processes such as extrusion molding, cutting, welding, or screwing to create window and door frames and sashes. However, PVC windows and doors are usually modular structures. When exposed to the outdoors for extended periods, they are subjected to wind, sun, rain, and environmental pollution, causing them to gradually age and lose their flexibility. This leads to deformation at the window frame joints, resulting in gaps and air leakage.

[0003] Therefore, we propose a corner reinforcement structure for PVC windows and doors. Utility Model Content

[0004] The purpose of this utility model is to provide a corner reinforcement structure for PVC windows and doors to solve the problem mentioned in the background art that PVC windows and doors will gradually age and lose their toughness due to long-term exposure to the outdoors and exposure to wind, sun, rain, environmental pollution and other atmospheric environmental erosion, resulting in deformation at the window frame joints and causing air leakage through gaps.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example

[0019] Please see Figures 1-3 The diagram shows a corner reinforcement structure for a PVC window and door, including a base plate 1, a side plate 2 inserted into the base plate 1, a fixing block 3 at the junction of the side plates 2, a limiting rod 4 inside the fixing block 3, a spring 5 sleeved on the outside of the limiting rod 4, a pressure block 6 rotatably connected to the limiting rod 4, a fixing plate 7 fixedly connected to the pressure block 6, and a double-sided sealing gasket 8 on one side of the fixing plate 7.

[0020] Furthermore, the fixing block 3 has a positioning groove, and the positioning groove is equipped with a sealing cover 10. The positioning groove is specially opened inside the fixing block and is used to fix the fixing block in cooperation with the screw. The addition of the sealing cover makes the surface of the fixing block aesthetically pleasing.

[0021] Furthermore, the fixing block 3 has two connecting blocks 9 inside, and the connecting blocks 9 are threadedly connected to the limiting rod 4. The fixing block has two connecting blocks inside, and the connecting blocks are tightly connected to the limiting rod by means of threads. By rotating the limiting rod, its position in the connecting block can be easily adjusted, thereby achieving fine adjustment of the sealing pressure. This ensures that the sealing gasket is always tightly attached to the door and window frame, maintaining the best sealing effect and reducing maintenance difficulty and cost.

[0022] Furthermore, a groove is provided at one end of the limiting rod 4, and the other end of the limiting rod 4 is rotatably connected to the pressure block 6. The groove at one end of the limiting rod and the rotatable connection between the other end and the pressure block greatly facilitates installation and adjustment. During installation, the groove can serve as a tool's leverage point, allowing the limiting rod to be easily screwed into or out of the connecting block, thus simplifying the installation steps and improving work efficiency. The rotatable connection between the other end of the limiting rod and the pressure block allows the pressure block to rotate and fine-tune relative to the limiting rod within a certain range, thereby more accurately adapting to minor deformations or unevenness of the door and window frames. This ensures that the sealing gasket always fits tightly against the door and window frames, effectively preventing the intrusion of wind, rain, dust, and noise, and improving the sealing performance of the doors and windows.

[0023] Furthermore, a pressure ring 601 is provided on the side of the pressure block 6 near the limiting rod 4. The pressure ring 601 tightly presses against one end of the limiting rod 4. By cleverly setting the pressure ring on the side of the pressure block near the limiting rod, and by ensuring that the pressure ring can tightly press against one end of the limiting rod, the pressure block can transmit pressure to the limiting rod more evenly and effectively when subjected to spring or external adjustment force. At the same time, it ensures the continuity and stability of pressure and avoids the problem of sealing failure caused by uneven pressure distribution.

[0024] Furthermore, a groove is provided on the inner side of the fixing block 3. The groove is tightly pressed against the inner wall of the base plate 1. Through the groove specially provided on the inner side of the fixing block, the groove and the inner wall of the base plate are tightly pressed together, which can effectively prevent external elements such as rainwater, dust and air from seeping into the interior of the sealing structure through the gaps, thereby greatly improving the sealing performance of the doors and windows. This not only improves the structural stability but also facilitates installation and positioning.

[0025] In this solution, the workflow is as follows: First, prepare all necessary components, including base plate 1, side plate 2, fixing block 3, limit rod 4, spring 5, pressure block 6, fixing plate 7, double-sided sealing gasket 8, connecting block 9, sealing cover 10, and installation tools such as screwdrivers and wrenches that may be needed.

[0026] Place base plate 1 flat on the workbench, ensuring its surface is flat and free of debris.

[0027] Insert the side plate 2 into the base plate 1 according to the angle and position required by the design, ensuring that the insertion is tight and without looseness.

[0028] At the junction of side plate 2, accurately place fixing block 3 to ensure that it fits tightly with both bottom plate 1 and side plate 2.

[0029] The inner side of the fixing block 3 has a groove, and it is necessary to ensure that the groove is tightly pressed against the inner wall of the base plate 1 to enhance the structural stability.

[0030] Inside the fixed block 3, the connecting block 9 is placed according to the design requirements, and its position is ensured to be accurate.

[0031] Align the slotted groove at one end of the limiting rod 4 with the threaded hole of the connecting block 9, and screw it in with a screwdriver or other tools until it is tightly threaded into the connecting block 9.

[0032] Ensure that the limiting rod 4 can move freely inside the fixed block 3, but is moderately restrained by the spring 5.

[0033] The spring 5 is sleeved on the outside of the limiting rod 4, ensuring that its two ends are in contact with the fixing block 3 and the pressure block 6 respectively.

[0034] Press the pressure ring 601 of the pressure block 6 close to the limit rod 4 tightly onto one end of the limit rod 4 to ensure that the two are tightly connected without any looseness.

[0035] Check whether the pressure block 6 can move freely under the action of the spring 5 and can be tightly pressed onto the fixed plate 7 when needed.

[0036] Secure the fixing plate 7 to the pressure block 6, ensuring that the connection is firm and secure.

[0037] Attach a double-sided sealing gasket 8 to one side of the fixing plate 7, ensuring that it is flat and wrinkle-free and can fit tightly against the door and window frame.

[0038] If the fixing block 3 has a positioning groove, the sealing cover 10 should be accurately placed in the positioning groove, and it should be ensured that it is flat and seamless with the surface of the fixing block 3.

[0039] The addition of the sealing cap 10 can further enhance the sealing performance and aesthetics of the structure.

[0040] After all components are installed, inspect the entire corner reinforcement structure to ensure that all connections are tight and secure.

[0041] The position of the limit rod 4 and the preload of the spring 5 are adjusted to achieve the best sealing effect and strength requirements.
