Description

Technical Field

[0001] The utility model belongs to the technical field of door and window design, and particularly relates to a reinforced door and window and a water-proof door and window. Background Art

[0002] Reference Figure 3 There is a door and window, including a first main frame 100, a pressure line 200 and a first transparent panel 300, wherein the pressure line 200 and the first transparent panel 300 are both installed on the first main frame 100 and the pressure line 200 cooperates with the first main frame 100 to press the first transparent panel 300; wherein the first main frame 100 includes a first buckle portion 110 recessed forward and a second buckle portion 120 recessed backward, and the pressure line 200 includes a forward protruding barb 220 and a backward protruding barb 220.

[0003] In order to facilitate the installation of the wire pressing 200, the prior art generally sets a first inclined surface 150 on the first snap-on portion 110 and the second snap-on portion 120, and sets a corresponding second inclined surface 240 on the barb 220, so that the barb 220 is guided to slide into the first main frame 100 through the cooperation of the first inclined surface 150 and the second inclined surface 240, so that the first snap-on portion 110 and the second snap-on portion 120 are snap-connected with the corresponding barb 220.

[0004] However, although this method facilitates the installation of the pressing wire, it weakens the fixing force of the pressing wire. When the first transparent panel encounters a strong wind, the first transparent panel will press the pressing wire, causing the inverted hook to escape from the first main frame, and then the first transparent panel will fly out of the first main frame due to the loss of the pressure of the pressing wire, posing a great safety hazard.

[0005] Therefore, the existing technology needs to be improved and developed. Utility Model Content

[0006] The utility model aims to provide a reinforced door and window and a water-seepage-proof door and window, which solves the problem of insufficient fixing force of the pressure wire in the existing door and window, strengthens the fixing of the pressure wire, and thus achieves the effect of improving the safety of the door and window.

[0007] In a first aspect, the utility model provides a reinforced door and window, comprising a first main body frame, a pressing line and a first transparent panel, wherein the pressing line and the first transparent panel are both mounted on the first main body frame and the pressing line cooperates with the first main body frame to press the first transparent panel tightly; the first main body frame comprises a first buckle portion that is concave forward and a second buckle portion that is concave backward, wherein the first buckle portion is closer to the first transparent panel than the second buckle portion;

[0008] The pressure line includes a reverse curved portion and a barb, the reverse curved portion includes a curved portion that bends from top to bottom and forward, and a folded portion that tilts from bottom to top and forward, the curved portion and the folded portion are connected to form a pointed end, the end of the folded portion away from the pointed end abuts against the first buckle portion while the pointed end abuts against the first main body frame; the barb is buckled and connected to the second buckle portion.

[0009] The reinforced doors and windows provided by the utility model provide a stronger fixing force than the undercut through the reverse curved portion, so that the pressing line is more firm, thereby better resisting the impact of strong winds and effectively ensuring the safety of the doors and windows when in use.

[0010] Furthermore, the crimping line also includes a crimping portion connected to the upper end of the curved portion and extending forward from the upper end of the curved portion to form a cantilever, and one end of the crimping portion away from the upper end of the curved portion cooperates with the first main frame to be crimped on the first transparent panel.

[0011] When the first transparent panel is impacted by strong wind, the elastic force of the inflection portion is converted into the pressure of the crimping portion acting on the first transparent panel, thereby fastening the first transparent panel.

[0012] Furthermore, at least two contact portions are provided at one end of the crimping portion away from the upper end of the curved portion, and all the contact portions are arranged at intervals along the up-down direction and are crimped on the first transparent panel in cooperation with the first main frame.

[0013] Avoiding the first transparent panel from being broken due to excessive concentration of force is beneficial to protecting the first transparent panel.

[0014] Furthermore, the end surfaces of all the contact portions are arc surfaces.

[0015] The curved surface is more conducive to protecting the first transparent panel and preventing the first transparent panel from breaking.

[0016] Furthermore, the thickness of the crimping portion is greater than the thickness of the inflection portion.

[0017] In a second aspect, the utility model provides a water seepage-proof door and window, comprising a main window and a secondary window, wherein the secondary window is the aforementioned reinforced door and window;

[0018] The main window includes a second main frame, a sash frame and a second transparent panel, wherein the second transparent panel is fixedly mounted on the sash frame; the sash frame is rotatably connected to the second main frame; the second main frame is spliced ​​with the first main frame and the frontmost side of the second main frame is located behind the frontmost side of the first main frame.

[0019] Furthermore, the frontmost side of the first main frame is provided with a first protrusion protruding backwards; the frontmost side of the second main frame is provided with a bearing platform protruding forwards;

[0020] One surface of the first protrusion is in close contact with the surface of the carrying platform, and the other surface is in close contact with the frontmost side of the second main frame.

[0021] Furthermore, a second convex portion protruding backward is further provided at the frontmost side of the first main frame, and the second convex portion is arranged below the first convex portion at intervals in the up-down direction; the bearing platform is located between the first convex portion and the second convex portion;

[0022] One surface of the second protrusion is in close contact with the surface of the carrying platform.

[0048] It should be noted that the “front and rear directions” mentioned below are based on the Figure 1 The directions of the arrows are for reference only, with the direction pointing “forward” pointing to the outdoors and the direction pointing “backward” pointing to the indoors.

[0049] Reference Figure 1 and attached Figure 2 The utility model provides a reinforced door and window, comprising a first main body frame 100, a pressing line 200 and a first transparent panel 300, wherein the pressing line 200 and the first transparent panel 300 are both installed on the first main body frame 100 and the pressing line 200 cooperates with the first main body frame 100 to press the first transparent panel 300; the first main body frame 100 comprises a first buckle portion 110 recessed forward and a second buckle portion 120 recessed backward, wherein the first buckle portion 110 is closer to the first transparent panel 300 than the second buckle portion 120;

[0050] The pressure line 200 includes a reverse curved portion 210 and a hook 220. The reverse curved portion 210 includes a curved portion 211 that bends forward from top to bottom and a folded portion 212 that tilts forward from bottom to top. The curved portion 211 and the folded portion 212 are connected to form a tip 213. The end of the folded portion 212 away from the tip 213 abuts against the first snap portion 110 while the tip 213 abuts against the first main frame 100. The hook 220 is snap-connected with the second snap portion 120.

[0051] In this embodiment, when installing the pressing wire 200, the hook 220 is first buckled and connected to the second buckle part 120, and then the reverse curved part 210 is pressed into the first buckle part 110. The curved part 211 is designed to bend from top to bottom and forward, and the folded part 212 is designed to be inclined from bottom to top and forward. In the process of installing the pressing wire 200, the folded part 212 plays a role in guiding the reverse curved part 210 to slide into the first main frame 100. During the sliding process, the folded part 212 is subjected to force so that the curved part 211 is deformed and accumulates elastic potential energy. When the folded part 212 completely slides into the first main frame 100, the curved part 211 is deformed and accumulates elastic potential energy. After being inserted into the main frame 100, the elastic potential energy of the curved portion 211 is released and restored to its original state, so that the tip 213 abuts against the first main frame 100 and one end of the folded portion 212 abuts against the first buckle portion 110. During the entire installation process, the guiding effect of the folded portion 212 makes it easier for the user to install the pressure wire 200. At the same time, relying on the recovery ability of the curved portion 211, the folded portion 212 can be automatically abutted against the first buckle portion 110, and the tip 213 abuts against the first main frame 100, effectively ensuring that the pressure wire 200 is firmly fixed.

[0052] In actual application, when the first transparent panel 300 encounters the impact of strong external wind, its impact force will be converted into pressure on the pressure line 200, and the pressure will force the end of the pressure line 200 close to the first transparent panel 300 to bend inward and upward. Although the tip 213 no longer abuts against the first main frame 100, the folding portion 212 still abuts against the first buckle portion 110. Therefore, the folding portion 212 resists the pressure and forces the inflection portion 210 to deform. The elastic force generated by the deformation of the inflection portion 210 is converted into pressure to act on the first transparent panel 300 and resist the impact force, which is equivalent to using the impact force to increase the fixing force of the first transparent panel 300. Compared with the existing method, the fixing effect of the pressure line 200 is enhanced, effectively ensuring that the pressure line 200 is not easy to fall off the first main frame 100 when the doors and windows encounter strong wind impact, thereby improving the safety of the doors and windows.

[0053] In certain embodiments, referring to Figure 2 The pressing wire 200 also includes a crimping portion 230 connected to the upper end of the curved portion 211 and extending forward from the upper end of the curved portion 211 to form a cantilever. One end of the crimping portion 230 away from the upper end of the curved portion 211 cooperates with the first main body frame 100 to be crimped on the first transparent panel 300. The pressing wire 200 is lifted up to cause the reverse curved portion 210 to deform. The elastic force of the reverse curved portion 210 is converted into a pressure of the crimping portion 230 acting on the first transparent panel 300, thereby achieving the fastening of the first transparent panel 300. In addition, when the first transparent panel 300 is hit by strong wind, the impact force will be concentrated and transmitted to the reverse curved portion 210 through the crimping portion 230, so that most of the impact force is converted into a fixing force on the first transparent panel 300.

[0054] In certain embodiments, referring to Figure 2At least two contact portions 231 are provided at one end of the crimping portion 230 away from the upper end of the curved portion 211, and all the contact portions 231 are arranged at intervals in the up-down direction and are pressed on the first transparent panel 300 in cooperation with the first main frame 100. The pressure exerted by the crimping portion 230 on the first transparent panel 300 is separated and transmitted to the first transparent panel 300 by the multiple contact portions 231, thereby avoiding excessive concentration of force and causing the first transparent panel 300 to break, which is beneficial to protecting the first transparent panel 300.

[0055] In certain embodiments, referring to Figure 2 , the end surfaces of all the contact portions 231 are arc surfaces. Compared with sharp edges and corners, the arc surface is more conducive to protecting the first transparent panel 300 and preventing the first transparent panel 300 from being broken.

[0056] In certain embodiments, referring to Figure 2 The thickness of the crimping portion 230 is greater than that of the inflected portion 210. As the main component for transmitting pressure, the crimping portion 230 often requires a certain strength to better transmit pressure, while the inflected portion 210, as a component for converting elastic force and pressure, requires a certain deformation ability. Therefore, the thickness of the crimping portion 230 is larger and the thickness of the inflected portion 210 is smaller.

[0057] Reference Figure 1 and attached Figure 4 The utility model provides a water-seepage-proof door and window, comprising a main window 400 and a secondary window 500, wherein the secondary window 500 is the reinforced door and window of the above embodiment;

[0058] The main window 400 includes a second main frame 410, a sash frame 420 and a second transparent panel 430, wherein the second transparent panel 430 is fixedly installed in the sash frame 420; the sash frame 420 is rotatably connected to the second main frame 410; the second main frame 410 is spliced ​​with the first main frame 100 and the frontmost side of the second main frame 410 is located behind the frontmost side of the first main frame 100.

[0059] In this embodiment, for a door and window including a main window 400 and a sub-window 500, the sub-window 500 is generally arranged above or below the main window 400 and is spliced ​​with the main window 400 as a whole. In addition, the first transparent panel 300 in the sub-window 500 is generally fixed in the first main frame 100 and remains stationary, so the sub-window 500 generally pays more attention to strength, while the second transparent panel 430 in the main window 400 is generally fixed in the sash frame 420 and moves with the sash frame 420, thereby realizing the opening and closing of the door and window, so the main window 400 generally pays more attention to water seepage prevention.

[0060] Since the first main frame 100 is spliced ​​and connected with the second main frame 410, there is inevitably a gap (referred to as the first gap 610) between the first main frame 100 and the second main frame 410. Figure 5 The first gap 610 generally extends in the up-down direction and the opening communicating with the outside is opposite to the sash frame 420 in the up-down direction. At the same time, since the sash frame 420 can move relative to the second main frame 410, there is inevitably a gap (referred to as the second gap 620) between the sash frame 420 and the second main frame 410. When the existing doors and windows are exposed to external wind and rain, rainwater will accumulate in the second gap 620. Although the gap of the first gap 610 is small enough to suppress the infiltration of rainwater to a certain extent, the rainwater in the second gap 620 is not drained away in time, so that the first gap 610 is immersed in rainwater for a long time, which inevitably causes rainwater to infiltrate the first gap 610 (for example, capillary phenomenon occurs), and then the problem of water seepage in the doors and windows may occur.

[0061] In this regard, in certain embodiments, reference is made to the attached Figure 6 , Attachment Figure 7 and attached Figure 8 The frontmost side of the first main frame 100 is provided with a first protrusion 130 protruding backward; the frontmost side of the second main frame 410 is provided with a carrying platform 411 protruding forward;

[0062] One surface of the first protrusion 130 is in close contact with the surface of the carrying platform 411 and the other surface is in close contact with the frontmost side of the second main frame 410 .

[0063] Taking the auxiliary window 500 located above the main window 400 as an example, the first main frame 100 is spliced ​​with the second main frame 410 and supported by the supporting platform 411. On the one hand, the supporting platform 411 blocks the gap between the front side of the first main frame 100 and the second main frame 410 (that is, the original first gap 610). On the other hand, a gap extending in the front-to-back direction is formed between the supporting platform 411 and the first protrusion 130 (that is, the third gap 630). The third gap 630 is connected with the original first gap 610 to form a new first gap 610. Since the opening of the third gap 630 connected to the outside world is no longer facing the sash frame 420 in the up-down direction, the opening of the new first gap 610 connected to the outside world is no longer facing the sash frame 420 in the up-down direction, thereby avoiding the opening from being immersed in rainwater for a long time (although the opening faces the outside world forward, since the rainwater from the outside world always tends to fall due to gravity, rainwater will not accumulate at the opening for a long time, so the opening will not be immersed in rainwater for a long time).

[0064] In addition, under the action of gravity of the auxiliary window 500, it can ensure that the first protrusion 130 is in close contact with the bearing platform 411, which is conducive to maintaining the gap size of the third gap 630 and preventing it from being easily enlarged, thereby further suppressing the infiltration of external rainwater.

[0065] For details, please refer to the attached Figure 6 For example, in the first embodiment, the first protrusion 130 includes a first boss 131 extending backward, the lower surface of the first boss 131 is in close contact with the upper surface of the supporting platform 411 and the rear end surface is in close contact with the frontmost side of the second main frame 410 .

[0066] Reference Figure 7 For example, in the second embodiment, the first protrusion 130 includes a first boss 131 extending backward and a second boss 132 extending upward and connected to the rear end of the first boss 131. The lower surface of the first boss 131 is in close contact with the upper surface of the bearing platform 411, and the rear end surface of the second boss 132 is in close contact with the frontmost side of the second main frame 410. The second boss 132 can further increase the gap length between the first protrusion 130 and the frontmost side of the second main frame 410, and the increase in the gap length is conducive to further improving the effect of inhibiting rainwater infiltration.

[0067] Reference Figure 8 For example, the first protrusion 130 includes a first protrusion 131 extending backward and a second protrusion 132 extending downward and connected to the rear end of the first protrusion 131. The lower surface of the second protrusion 132 is in close contact with the upper surface of the supporting platform 411 and the rear end surface is in close contact with the front side of the second main frame 410.

[0068] In certain embodiments, referring to Figure 8 and attached Fig. 9 The frontmost side of the first main frame 100 is also provided with a second protrusion 140 protruding backwards, and the second protrusion 140 is arranged below the first protrusion 130 at intervals in the up-down direction; the carrying platform 411 is located between the first protrusion 130 and the second protrusion 140;

[0069] One surface of the second protrusion 140 is in close contact with the surface of the carrying platform 411 .

[0070] In this embodiment, the cooperation between the first protrusion 130 and the second protrusion 140 can further increase the number and length of gaps between the first main frame 100 and the second main frame 410, thereby forming a gap with a longer length and a more tortuous extension path, thereby further suppressing the infiltration of external rainwater.

[0071] For details, please refer to the attached Figure 8 For example, in the third embodiment, the second protrusion 140 includes a third boss 141 extending backward, and the upper surface of the third boss 141 is in close contact with the lower surface of the carrying platform 411 .

[0072] Reference Fig. 9 For example, in the fourth embodiment, the second protrusion 140 includes a third protrusion 141 extending backward and a fourth protrusion 142 extending upward and connected to the rear end of the third protrusion 141 , and the upper surface of the fourth protrusion 142 is in close contact with the lower surface of the supporting platform 411 .

[0073] In certain embodiments, referring to Figure 8 and attached Fig. 9 When the supporting platform 411 is located between the first protrusion 130 and the second protrusion 140, the front end surface of the supporting platform 411 can also be in close contact with the first main frame 100, thereby further suppressing the infiltration of external rainwater by increasing the number and length of gaps between the first main frame 100 and the second main frame 410.

[0074] In certain embodiments, referring to Fig.10 , Attachment Fig.11 , Attachment Fig.12 and attached Fig.13 The frontmost side of the first main frame 100 is provided with a first convex portion 130 and a second convex portion 140 protruding backward, and the second convex portion 140 is arranged below the first convex portion 130 at intervals in the up-down direction; the frontmost side of the second main frame 410 is provided with a carrying platform 411 protruding forward, and the carrying platform 411 is located below the second convex portion 140;

[0075] One surface of the first protrusion 130 is in close contact with the frontmost side of the second main frame 410 ; one surface of the second protrusion 140 is in close contact with the surface of the supporting platform 411 and the other surface is in close contact with the frontmost side of the second main frame 410 .

[0076] Placing the supporting platform 411 below the second protrusion 140 can ensure that the second protrusion 140 and the supporting platform 411 are in close contact under the action of gravity of the auxiliary window 500, which is beneficial to maintaining the gap between the two and preventing it from increasing easily.
