Description

Technical Field

[0001] This application relates to the technical field of casement windows, and in particular to a casement window with seamless welded modular assembly. Background Technology

[0002] Casement windows are windows whose sashes open and close along a horizontal direction. Casement windows have advantages such as large opening area, good ventilation, good sealing, and excellent sound insulation, heat preservation, and water resistance.

[0003] Existing casement windows include a window frame, a window sash hinged to the window frame by hinges, and a glass panel set on the window sash. By welding and fixing multiple window frame profiles to form a window frame, and by welding and fixing multiple window sash profiles to form a window sash, the window sash with the glass panel can move in a certain horizontal direction under the hinge action, thus forming a casement window.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the window frame is formed by welding and fixing multiple window frame profiles, and the window sash is formed by welding and fixing multiple window sash profiles, which makes the assembly between window frame profiles and the assembly between window sash profiles less convenient. Summary of the Invention

[0005] To make the assembly of multiple window frame profiles and multiple window sash profiles more convenient, this application provides a casement window with seamless welding and modular assembly.

[0006] The casement window provided in this application, which features seamless welding and modular assembly, adopts the following technical solution:

[0007] A casement window with seamless welding and modular assembly includes a window frame assembled from window frame profiles and a window sash assembled from window sash profiles. Adjacent window frame profiles are assembled with a first connector, and adjacent window sash profiles are assembled with a second connector. The window sash is hinged to the window frame.

[0008] By adopting the above technical solution, the assembly between adjacent window frame profiles is realized under the connection of the first connector, and the assembly between adjacent window sash profiles is realized under the connection of the second connector. This makes the assembly between multiple window frame profiles and the assembly between multiple window sash profiles more convenient. Moreover, the first connector, the second connector, the window frame profiles and the window sash profiles can all be produced in a standardized modular manner, which improves work efficiency and shortens the delivery cycle.

[0009] Optionally, the window frame profile includes two side profiles and a connecting profile disposed between the two side profiles. Dovetail strips are fixedly connected to both opposite sides of the connecting profile. A connecting part that slides and connects with the dovetail strip is integrally formed on the side of the side profile closest to the connecting profile.

[0010] By adopting the above technical solution, under the sliding connection between the dovetail strip and the connecting part, the connecting profile is connected between the two side profiles, so that the side profiles and the connecting profile are assembled to form the window frame profile.

[0011] Optionally, the first connector includes a first corner bracket and a first corner piece, the first corner bracket being connected between adjacent side profiles via a first locking member, and the first corner piece being connected between adjacent connecting profiles.

[0012] By adopting the above technical solution, the connection between adjacent window frame profiles is achieved through the connection between the first corner bracket and the first corner piece.

[0013] Optionally, the first locking member includes a spring piece placed in the cavity of the first corner bracket, one side of the spring piece being bent to have a bent portion that extends outside the first corner bracket, the bent portion engaging with the inner wall of the side profile.

[0014] By adopting the above technical solution, the bent part is engaged with the inner wall of the side profile, thereby realizing the connection between adjacent side profiles.

[0015] Optionally, the first corner piece is stamped with an obliquely arranged snap-fit ​​piece, and the inner wall of the connecting profile is provided with a snap-fit ​​groove for engaging with the snap-fit ​​piece.

[0016] By adopting the above technical solution, the snap-fit ​​piece and the snap-fit ​​groove are snapped together, thereby realizing the connection between adjacent connecting profiles.

[0017] Optionally, the inner side of the side profile is provided with a fastening component to enhance the fastening effect.

[0018] By adopting the above technical solution, the fastening components reinforce the connection between the first corner bracket and the side profile.

[0019] Optionally, the fastening assembly includes a fastener threaded onto the inner side of the side profile, a push block slidably connected to the inside of the side profile and rotatably connected to the fastener, a piercing rod slidably connected to the first corner bracket and extending to the outside of the first corner bracket, and a thin film capsule fixed in the hollow part of the side profile by a fixing block. The thin film capsule is filled with adhesive, and the push block pushes the piercing rod to pierce the thin film capsule.

[0020] By adopting the above technical solution, rotating the fastener causes the fastener to push the push block to extend into the first corner code, so that the push block pushes the rupture rod, thereby rupturing the film capsule and causing the adhesive inside the film capsule to leak out, thus reinforcing the connection between the first corner code and the side profile.

[0021] Optionally, a guide block is fixedly connected to the periphery of the jacking rod, and a guide groove is provided in the first corner bracket to slide and connect with the guide block. An elastic element is fixedly connected between the guide block and the guide groove.

[0022] By adopting the above technical solution, the setting of the guide block, guide groove and elastic element enables the push block to smoothly push the top-breaking rod after it extends to the first corner code.

[0023] Optionally, the inner frame side of the window frame is provided with a limiting frame for limiting the window sash.

[0024] By adopting the above technical solution, the limiting frame is set to limit the window sash after it is closed.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Under the connection of the first connector, the assembly between adjacent window frame profiles is realized. Under the connection of the second connector, the assembly between adjacent window sash profiles is realized. This makes the assembly between multiple window frame profiles and multiple window sash profiles more convenient. Moreover, the first connector, the second connector, the window frame profiles and the window sash profiles can all be produced in a standardized modular manner, which improves work efficiency and shortens the delivery cycle.

[0027] 2. Rotate the fastener so that the fastener pushes the push block to extend into the first corner bracket, so that the push block pushes the rupture rod, thereby rupturing the film capsule and causing the adhesive inside the film capsule to leak out, thus reinforcing the connection between the first corner bracket and the side profile.

[0028] 3. The design of the guide block, guide groove, and elastic element allows the push block to smoothly push the top-breaking rod after it extends to the first corner bracket. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a casement window with seamless welded modular assembly. (Refer to...) Figure 1 and Figure 2 The seamless welded modular assembly casement window includes a window frame, a window sash hinged to the window frame by hinges, and a glass panel 1 set on the window sash; in order to limit the window sash after it is closed, a limit frame is provided on the inner frame side of the window frame, so that when the window sash is closed, the limit frame limits the window sash.

[0038] Reference Figure 2 and Figure 3 The window frame includes four window frame profiles 2 connected end to end. Each window frame profile 2 has a first bevel at both ends. The first bevels of two adjacent window frame profiles 2 abut against each other to form the corner of the window frame. The adjacent window frame profiles 2 are spliced ​​together by a first connector 3. The first connector 3 is embedded between the adjacent window frame profiles 2, so that the spliced ​​window frame does not expose the first connector 3.

[0039] The window sash consists of four window sash profiles connected end to end. Each window sash profile has a second bevel at both ends. The second bevels of two adjacent window sash profiles abut against each other to form the corner of the window sash. Adjacent window sash profiles are spliced ​​together by a second connector. The second connector is embedded between the adjacent window sash profiles so that the spliced ​​window sash does not expose the second connector.

[0040] Reference Figure 2 and Figure 3The window frame profile 2 and the window sash profile have the same structure but different sizes. Both the window frame profile 2 and the window sash profile include two side profiles 21 and a connecting profile 22 disposed between the two side profiles 21. Dovetail strips 221 are fixedly connected to the opposite sides of the connecting profile 22. The length direction of the dovetail strips 221 is consistent with the length direction of the connecting profile 22. A connecting part 211 is integrally formed on the side of the side profile 21 closest to the connecting profile 22. A dovetail groove corresponding to the position of the dovetail strip 221 is opened on the connecting part 211. The dovetail strip 221 is slidably connected to the dovetail groove corresponding to the position. Thus, the two side profiles 21 are connected to the opposite sides of the connecting profile 22.

[0041] Reference Figure 2 and Figure 3 The limiting frame includes four limiting profiles 11 connected end to end. The side profile 21 of the window frame profile 2 located inside the room is the first side profile. The number of limiting profiles 11 is the same as the number of the first side profiles and corresponds one-to-one. The limiting profiles 11 are fixedly connected to the first side profiles at the corresponding positions. Thus, the limiting profiles 11 can limit the window sash after it is closed.

[0042] Reference Figure 3 and Figure 4 The connecting profile 22 included in the window sash profile is the second connecting profile. Each second connecting profile is fixedly connected to a sliding track 12 that is slidably connected to the glass plate 1 on the side closest to the glass plate 1. When the four window sash profiles are spliced ​​together, the four sliding tracks 12 together limit the four sides of the glass plate 1.

[0043] Reference Figure 2 and Figure 3 In this embodiment, the first connector 3 and the second connector have the same structure but different sizes, so the first connector 3 is used as an example in this application. The first connector 3 includes two oppositely arranged first corner brackets 31 and a plurality of first corner pieces 32 located between the two first corner brackets 31; the cross-sections of the first corner brackets 31 and the first corner pieces 32 are both L-shaped; the first corner brackets 31 are provided with two first locking members for locking two adjacent side profiles 21.

[0044] Reference Figure 2 and Figure 3The first locking element includes a spring piece 311 with a V-shaped cross-section placed in the cavity of the first corner bracket 31. An extension hole 312 communicating with the cavity is provided on the side of the first corner bracket 31. One side of the spring piece 311 is bent with a bend corresponding to the position of the extension hole 312. The end of the bend away from the spring piece 311 extends through the extension hole 312 to the outside of the first corner bracket 31. The inner wall of the side profile 21 is provided with a locking groove corresponding to the position of the bend. When the extension hole 312 is not connected to the locking groove, the end of the bend away from the spring piece 311 abuts against the inner wall of the side profile 21, and the spring piece 311 is in a compressed state with an outward tension. When the extension hole 312 corresponds to and communicates with the locking groove, the bend is engaged in the locking groove under the elastic action of the spring piece 311. Thus, the first corner bracket 31 locks the adjacent side profile 21.

[0045] Reference Figure 2 and Figure 3 To improve the overall strength of the connecting profile 22, two spaced reinforcing ribs 222 are fixedly connected to the inner wall of the connecting profile 22. The length direction of the reinforcing ribs 222 is consistent with the length direction of the connecting profile 22. The presence of the two reinforcing ribs 222 divides the inner wall of the connecting profile 22 into three insertion channels. The number of first corner pieces 32 is consistent with the number of insertion channels and corresponds one-to-one. Each first corner piece 32 is stamped with an obliquely arranged snap-fit ​​piece 321. The inner walls of the connecting profile 22 and the reinforcing ribs 222 are provided with snap-fit ​​grooves corresponding to the positions of the snap-fit ​​pieces 321. When the first corner piece 32 is inserted into the insertion channel, the snap-fit ​​piece 321 bends due to the force. At this time, the snap-fit ​​piece 321 has an outward elastic force. When the snap-fit ​​piece 321 corresponds to the position of the snap-fit ​​groove, the snap-fit ​​piece 321 resets and snaps into the snap-fit ​​groove. Thus, the first corner piece 32 locks the adjacent connecting profile 22.

[0046] Reference Figure 5 and Figure 6 After the initial locking between adjacent side profiles 21 is completed by the first angle bracket 31, a fastening assembly 4 is provided on the inner side of the side profile 21 to strengthen the fastening. The fastening assembly 4 includes a fastener 41 threaded to the inner side of the side profile 21, a push block 42 slidably connected to the side profile 21 and rotatably connected to the fastener 41, a jacking rod 43 slidably connected to the first angle bracket 31 and extending to the outside of the first angle bracket 31, and a thin film capsule 44 fixed in the hollow part of the side profile 21.

[0047] Reference Figure 5 and Figure 6A sliding groove 212 communicating with the hollow part of the side profile 21 is provided in the side profile 21. The push block 42 is slidably connected in the sliding groove 212, and under the limiting action of the sliding groove 212, the push block 42 cannot rotate in the sliding groove 212. A connecting groove 315 corresponding to the position of the sliding groove 212 is provided on the first corner bracket 31. After the bent part of the spring piece 311 is engaged in the locking groove, the sliding groove 212 and the connecting groove 315 are connected. Under the pushing action of the fastener 41, the push block 42 extends into the first corner bracket 31 through the connecting groove, so that the push block 42 can push the puncturing rod 43 to puncture the film capsule 44.

[0048] Reference Figure 5 and Figure 6 The sliding direction of the jacking rod 43 is perpendicular to the sliding direction of the push block 42, and the end of the jacking rod 43 away from the push block 42 extends to the end of the first corner bracket 31. The end of the push block 42 away from the fastener 41 is provided with a first inclined surface 421, and the end of the jacking rod 43 located inside the first corner bracket 31 is provided with a second inclined surface 431. The first inclined surface 421 and the second inclined surface 431 are adapted to each other so that when the first inclined surface 421 abuts against the second inclined surface 431, the push block 42 can push the jacking rod 43 to move away from the push block 42.

[0049] In this embodiment, the fastener 41 is a hexagon socket head cap screw, which is threaded to the side profile 21. The end of the hexagon socket head cap screw extending to the sliding groove 212 is rotatably connected to the push block 42. In order to prevent the hexagon socket head cap screw from being exposed and to reduce the occurrence of the hexagon socket head cap screw head obstructing the closing of the window sash, a recess 411 matching the head of the hexagon socket head cap screw is provided on the inner side of the side profile 21. After the piercing rod 43 pierces the membrane capsule 44, the head of the hexagon socket head cap screw is located in the recess 411.

[0050] Reference Figure 5 and Figure 6 To ensure that the first inclined surface 421 can abut against the second inclined surface 431 after the pusher block 42 extends to the first corner bracket 31, allowing the pusher block 42 to smoothly push the jacking rod 43, a guide block 432 is fixedly connected to the periphery of the jacking rod 43. A guide groove 313 corresponding to the position of the guide block 432 is formed in the first corner bracket 31. The length direction of the guide groove 313 is consistent with the length direction of the jacking rod 43. The end of the guide block 432 away from the jacking rod 43 extends into the guide groove 313, and the guide block 432 is slidably connected to the guide groove 313. An elastic element 314 is fixedly connected to one side of the guide block 432, and the end of the elastic element 314 away from the guide block 432 is fixedly connected to the inner wall of the guide groove 313. In this embodiment, the elastic element 314 is a spring.

[0051] In the initial state, the push block 42 is located within the sliding groove 212, so the push block 42 will not affect the insertion of the first angle bracket 31 into the hollow part of the side profile 21, allowing the bent part of the spring piece 311 to smoothly engage with the locking groove. Because the hexagonal socket bolt is rotatably connected to the push block 42, the hexagonal socket bolt cannot fall off the side profile 21, reducing the occurrence of lost hexagonal socket bolts and improving assembly efficiency.

[0052] Reference Figure 5 and Figure 6 The film capsule 44 is filled with adhesive. In this embodiment, preferably, the film capsule 44 is a polyvinyl alcohol film, and the adhesive is glue. A fixing block 441 is fixedly connected to the hollow part of the side profile 21, and the film capsule 44 is fixed to the side of the fixing block 441 near the rupture rod 43. The end of the rupture rod 43 away from the push block 42 is integrally formed with a tip for rupturing the film capsule 44, thereby rupturing the film capsule 44 through the tip, allowing the adhesive inside the film capsule 44 to leak out, and then fixing the first corner bracket 31 more firmly in the side profile 21 through the adhesive. At the same time, the operator can also wet the tip of the rupture rod 43 before assembly. The polyvinyl alcohol film is easily broken when wet, making the film capsule 44 easier to rupture.

[0053] The implementation principle of a seamless welded modular assembly casement window in this application embodiment is as follows: Under the sliding connection of the dovetail strip 221 and the dovetail groove, the connecting profile 22 is connected between the two side profiles 21, so that the side profiles 21 and the connecting profile 22 are assembled to form the window frame profile 2; the two ends of the first corner bracket 31 are respectively inserted into the adjacent side profiles 21, and the bent part is locked in the locking groove to realize the connection between the adjacent side profiles 21; the two ends of the first corner piece 32 are respectively inserted into the... The connecting piece 321 is inserted into the adjacent connecting profile 22 and engages with the snap-fit ​​groove to achieve the connection between the adjacent connecting profiles 22. Then, the internal hex bolt is rotated, causing the internal hex bolt to push the push block 42 into the first corner bracket 31, so that the push block 42 pushes the piercing rod 43, thereby piercing the film capsule 44 and causing the adhesive inside the film capsule 44 to leak out, thus reinforcing the connection between the first corner bracket 31 and the side profile 21; thus completing the assembly of the window frame. Following the above steps, the window sash is assembled, and the glass plate 1 is confined in the window sash, completing the assembly of the entire casement window. The whole process makes the assembly between multiple window frame profiles 2 and the assembly between multiple window sash profiles more convenient, and the first connector 3, the second connector, the window frame profile 2 and the window sash profile can all be produced in a standardized modular manner, improving work efficiency and shortening the delivery cycle.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
