Description

Technical Field

[0001] This utility model relates to the field of PVC window technology, specifically to a deformation-resistant PVC window. Background Technology

[0002] PVC windows, also known as uPVC windows, are window frames made of polyvinyl chloride (PVC) plastic and are commonly found in modern buildings. Their main characteristics include excellent thermal insulation and corrosion resistance, making them superior to traditional metal window frames in terms of energy efficiency and durability. Due to their lightweight, easy-to-process and moldable material, combined with good sound insulation and waterproofing, PVC windows are widely used in residential and commercial buildings.

[0003] Due to technological limitations, existing PVC windows are typically manufactured by welding the window frame to the outer PVC material, while the interior of the window frame remains separate. This makes the corners of the window frame prone to cracking or deformation under pressure, thus reducing the lifespan of the PVC windows. Utility Model Content

[0004] This utility model proposes a deformation-resistant PVC window, which improves the service life of PVC windows.

[0005] The technical solution of this utility model is as follows: A deformation-resistant PVC window includes a first window frame and a second window frame. A positioning block is provided on one side of the first window frame, and a positioning groove is provided on one side of the second window frame. The positioning block is slidably connected to the inner wall of the positioning groove. A corner bushing is provided at the corner where the first window frame and the second window frame intersect. The corner bushing has an "L" shaped structure. Fixing mechanisms connecting the first window frame and the second window frame are provided on both sides of the corner bushing.

[0006] Furthermore, both the first and second window frames are equipped with fixing blocks inside, and each fixing block has a fixing hole. The fixing hole has a frustum-shaped structure, and the fixing mechanism is slidably connected to the inside of the fixing hole.

[0007] Furthermore, both sides of the corner bushing are provided with fixing posts, and the fixing posts and fixing holes are on the same axis. The diameter of the fixing posts is smaller than the diameter of the small end of the fixing holes. The fixing mechanism includes several sliding components that engage with the side of the fixing block, and there are at least four sliding components.

[0008] Furthermore, the sliding assembly includes a rotating plate, a connecting rod, a fixed plate, and a first elastic element. The fixed post has at least four accommodating spaces arranged circumferentially around the fixed post. One end of the rotating plate is rotatably connected to the side of the accommodating space away from the corner bushing, and the other end of the rotating plate is rotatably connected to one end of the connecting rod. The rotating plate is also slidably connected to the inner wall of the fixed hole. The other end of the connecting rod is rotatably connected to the fixed plate. The fixed plate is located on the other side of the accommodating space and is slidably connected to the inner wall of the accommodating space. One end of the first elastic element is fixedly connected to the bottom of the accommodating space, and the other end of the first elastic element is fixedly connected to the fixed plate. The side of the fixed plate away from the rotating plate abuts against the side of the fixed block away from the corner bushing.

[0009] Furthermore, guide grooves are provided on both sides of the accommodating space, and guide blocks are provided on both sides of the fixing plate, with the guide blocks slidingly connected to the inner wall of the guide groove.

[0010] Furthermore, an elastic component is provided on the side of the corner bushing near the fixing block. The elastic component includes a first elastic plate and several second elastic elements. One end of each second elastic element is fixedly connected to the side of the corner bushing near the fixing block, and the other end of each second elastic element is fixedly connected to the elastic plate, and the elastic plate abuts against the fixing block.

[0011] The working principle and beneficial effects of this utility model are as follows:

[0012] This invention, by incorporating positioning blocks and slots, ensures precise positioning of the window frame during assembly, guaranteeing accurate installation and maintaining its verticality and horizontality, thus improving installation quality. Simultaneously, it enables faster and more convenient alignment and fixing, reducing adjustments and errors during installation and saving time and labor costs. Corner protectors at the corners of the window frames create integrated right angles in the steel structure, effectively enhancing the strength and stability of the connection between the first and second window frames, reducing the risk of deformation or damage, and extending the service life of the PVC window. Furthermore, the fixing mechanism on the corner protectors effectively enhances the stability and strength of the overall structure, reducing window frame deformation and movement. During installation, the fixing mechanism pre-fixes adjacent window frames, facilitating welding of external plastic materials and improving work efficiency. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] refer to Figure 1-8 A type of deformation-resistant PVC window includes a first window frame 1 and a second window frame 101 (it should be noted that the window frame is usually composed of four window frames, and this embodiment uses two window frames as an example). A positioning block 1012 is provided on one side of the first window frame 1, and a positioning groove 1011 is provided on one side of the second window frame 101. The positioning block 1012 is slidably connected to the inner wall of the positioning groove 1011. A corner insert 102 is provided at the corner where the first window frame 1 and the second window frame 101 meet. The corner insert 102 has an "L" shaped structure. The L-shaped structure design can effectively increase the overall strength of the corner insert 102 and significantly improve the stability and compressive strength of the window frame connection. Fixing mechanisms connecting the first window frame 1 and the second window frame 101 are provided on both sides of the corner insert 102.

[0025] By setting positioning blocks 1012 and positioning grooves 1011, the window frame can be precisely positioned during assembly, ensuring accurate installation and maintaining its verticality and horizontality, thus improving installation quality. Simultaneously, it allows for faster and more convenient alignment and fixing, reducing adjustments and errors during installation and saving time and labor costs. Corner inserts 102 at the corners of the window frames form an integrated steel structure right angle, effectively enhancing the strength and stability of the connection between the first window frame 1 and the second window frame 101, reducing the risk of window frame deformation or damage, and extending the service life of the PVC window. Furthermore, the fixing mechanism on the corner inserts 102 effectively enhances the stability and strength of the overall structure, reducing window frame deformation and movement. During installation, the fixing mechanism can pre-fix adjacent window frames, facilitating welding of external plastic materials and improving work efficiency.

[0026] Furthermore, both the first window frame 1 and the second window frame 101 are equipped with fixing blocks 103 inside, and the fixing blocks 103 are fixedly connected to the first window frame 1 and the second window frame 101. The fixing blocks 103 are equipped with fixing holes 104 inside, and the fixing holes 104 are frustoconical in shape. The fixing mechanism is slidably connected to the fixing holes 104. By slidably connecting the fixing mechanism to the fixing holes 104, the corner bushing 102 can be connected to the first window frame 1 or the second window frame 101 without manual operation by the staff, thereby improving the work efficiency of the staff.

[0027] The corner bushing 102 is provided with fixing posts 105 on both sides, and the fixing posts 105 and the fixing holes 104 are on the same axis. The diameter of the fixing posts 105 is smaller than the diameter of the small end of the fixing holes 104. The fixing mechanism includes several sliding components that engage with the side of the fixing block 103. There are at least four sliding components. The four sliding components can provide stable connection strength and save costs.

[0028] Specifically, the sliding assembly includes a rotating plate 2, a connecting rod 201, a fixed plate 202, and a first elastic element 203. The fixed post 105 is provided with at least four accommodating spaces 204, which are circumferentially arranged with the fixed post 105 as the center. One end of the rotating plate 2 is rotatably connected to the side of the accommodating space 204 away from the corner bushing 102, and the other end of the rotating plate 2 is rotatably connected to one end of the connecting rod 201. The rotating plate 2 is also slidably connected to the inner wall of the fixed hole 104. The other end of the connecting rod 201 is rotatably connected to the fixed plate 202. The fixed plate 202 is located on the other side of the accommodating space 204 and is slidably connected to the inner wall of the accommodating space 204. One end of the first elastic element 203 is fixedly connected to the bottom of the accommodating space 204, and the other end of the first elastic element 203 is fixedly connected to the fixed plate 202. The side of the fixed plate 202 away from the rotating plate 2 abuts against the side of the fixed block 103 away from the corner bushing 102.

[0029] When the staff installs the corner insert 102, one end needs to be inserted into the first window frame 1. During the movement of the corner insert 102, the rotating plate 2 on the fixing post 105 will contact the inside of the fixing hole 104. One end of the rotating plate 2 will be rotatably connected to the inner wall of the accommodating space 204, and the other end will drive the fixing plate 202 to move in the direction of compressing the first elastic member 203 through the connecting rod 201, so that the fixing plate 202 and the rotating plate 2 are in a contracted state. When the rotating plate 2 is disengaged from the fixing hole 104, the first elastic member 203 will be reset. Under the action of the first elastic member 203, the fixing plate 202 will be extended, thereby driving the rotating plate 2 to return to its original unfolded state through the connecting rod 201, so that the fixing block 103 abuts against the side of the fixing plate 202, thereby achieving the pre-fixation of the corner insert 102 (the window frame is usually not disassembled after installation).

[0030] To reduce friction between the rotating plate 2 and the fixing hole 104, the side of the rotating plate 2 closest to the inner wall of the fixing hole 104 can be designed as an arc shape. The arc shape design can reduce the contact area between the rotating plate 2 and the fixing hole 104, thereby reducing friction and making it easier for workers to install the corner bushing 102.

[0031] Secondly, to prevent the fixed plate 202 from shifting during movement, guide grooves 205 are provided on both sides of the accommodating space 204, and guide blocks 206 are provided on both sides of the fixed plate 202. The guide blocks 206 are slidably connected to the inner wall of the guide grooves 205. By setting the guide blocks 206 and guide grooves 205, the degree of freedom of the fixed plate 202 can be restricted, preventing the fixed plate 202 from shifting or misaligning during movement, thereby improving the movement stability of the fixed plate 202. At the same time, it can ensure that the first elastic element 203 is subjected to uniform force, thereby extending the service life of the first elastic element 203.

[0032] In this embodiment, an elastic component is provided on the side of the corner bushing 102 near the fixing block 103. The elastic component includes a first elastic plate 3 and a plurality of second elastic elements 301. Both the first elastic element 203 and the second elastic elements 301 are cylindrical compression springs. One end of each second elastic element 301 is fixedly connected to the side of the corner bushing 102 near the fixing block 103, and the other end of each second elastic element 301 is fixedly connected to the elastic plate 3. The elastic plate 3 abuts against the fixing block 103.

[0033] With the provided elastic components, when the worker installs the corner bushing 102, the surface of the elastic plate 3 will come into contact with the surface of the fixing block 103, the second elastic element 301 will be compressed, and the corner bushing 102 will push the fixing post 105 to continue moving into the fixing hole 104. When the side of the fixing plate 202 contacts the side of the fixing block 103, the second elastic element 301 has the force to restore its deformation, thereby improving the connection strength between the first window frame 1, the second window frame 101 and the corner bushing 102.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
