[0003] The fixing methods of traditional screen windows are various, mainly including screw fixing, slot fixing and built-in lock piece buckle fixing. The screen window fixed by screws needs to be unscrewed one by one when disassembled, which is not only cumbersome to operate, but also easy to lose screws, increasing the difficulty of reinstallation. Although the screen window fixed by the slot is relatively simple in the disassembly process, the slot may be aged or deformed after long-term use, causing the screen window to be difficult to disassemble or not firmly installed. Although the screen window fixed by the built-in lock piece buckle has a compact structure, it needs special tools and methods when disassembled, which is difficult for ordinary users to operate.

[0004] In addition, with the continuous increase of screen window types, such as aluminum alloy invisible screen window, aluminum alloy folding screen window, aluminum alloy frame diamond mesh screen window, etc., different types of screen windows also have their own problems in the process of disassembly. For example, the disassembly of the aluminum alloy invisible screen window needs to pry the bottom frame and unscrew the rail plug screw, which is complex to operate and easy to damage the screen window structure; the aluminum alloy folding screen window usually adopts an integral frame assembly method, and it is difficult to replace the screen independently, usually requiring original factory after-sales service; although the aluminum alloy frame diamond mesh screen window has the function of independent disassembly, the exposed screws may affect the appearance, and the disassembly switch position of the hidden hinge is not easy to find, increasing the disassembly difficulty.

[0005] In summary, the screen windows on the market currently have many inconveniences in the process of disassembly, which not only increases the maintenance cost and time cost of users, but also affects the service life and appearance of the screen window. Therefore, it is necessary to improve the hinge of the screen window, so that the hinge can be quickly disassembled and assembled, thereby improving the disassembly convenience of the screen window and reducing the maintenance difficulty of the user.

DETAILED DESCRIPTION

[0045] The present application will be further described in detail below in combination with test examples and specific embodiments. However, it should not be understood that the scope of the above-mentioned subject matter of the present application is limited to the following examples only, and any technology realized based on the content of the present application falls within the scope of the present application.

[0046] As Figure 1 and Figure 2 A window hinge, comprising a base 100 and a rotating member 200 capable of rotating around itself, the rotating member 200 comprising a base body 210 and a button 220 capable of telescopic slidingly arranged on the base body 210, further comprising a pivoting shaft 230, an elastic member 240 and a cover plate 250.

[0047] One end of the button 220 is fixedly provided with a pivot shaft 230, and an elastic member 240 is arranged between the base body 210 and the button 220. Under the elastic action of the elastic member 240, the button 220 and the pivot shaft 230 extend out of the base body 210 and are exposed. The extension direction of the button 220 is consistent with the direction in which the button 220 extends out of the base body 210, so that the extension length of the button 220 can change when the button 220 extends and retracts, thereby realizing the effect of extension or retraction.

[0048] The base 100 is provided with a mounting surface 121 and a pivot slot 110 matched with the pivot shaft 230. The mounting surface 121 is a slope or a curved surface gradually increasing from one end to the other end, and the higher end of the mounting surface 121 is connected to the pivot slot 110, so that the pivot shaft 230 can enter the pivot slot 110 through the mounting surface 121 when sliding on the mounting surface 121. The pivot shaft 230 is matched with the pivot slot 110, and after being inserted into the pivot slot 110 for connection, the pivot shaft 230 is placed in the pivot slot 110 and can rotate in the pivot slot 110.

[0049] The higher end of the mounting surface 121 is connected to the pivot slot 110, which can be directly connected or indirectly connected through other intermediate surfaces. In the case of direct connection, the mounting surface 121 is directly connected to the pivot slot. In the case of indirect connection through other intermediate surfaces, there can be other surfaces between the mounting surface 121 and the pivot slot 110, such as a transition flat surface.

[0050] When the hinge is disassembled, the button 220 only needs to be pressed to make the pivot shaft 230 disengage from the pivot slot 110, so that the rotating part 200 can be moved, thereby quickly separating the rotating part 200, realizing the quick disassembly of the base 100 and the rotating part 200. When installing, only the pivot shaft 230 needs to be aligned with the mounting surface 121, and the pivot shaft 230 slides on the mounting surface 121 from the lower end to the higher end of the mounting surface 121, so that the mounting surface 121 can compress the pivot shaft 230. When the pivot shaft 230 slides into the upper part of the pivot slot 110 from the mounting surface 121, the pivot shaft 230 extends out under the action of the elastic member 240 and extends into the pivot slot 110, realizing the quick installation of the rotating part 200 and the base 100. The design of the button 220 makes disassembly easy, and the mounting surface 121 is a slope or a curved surface gradually increasing from one end to the other end, which makes it only need to slide to realize installation when installing, without the need to press the button 220, thereby realizing quick and convenient disassembly and assembly.

[0051] As Figure 3, the installation surface 121 is an inclined surface, and the angle between the installation surface 121 and the bottom surface 123 of the base 100 is R, preferably 5°≤R≤30°. Generally, the smaller the angle, the smaller the resistance during installation, but the sliding distance is also longer, and the base 100 needs to be made longer, which is high in cost. In terms of small resistance, speed and cost during installation, it is preferred that the angle be 5°, 6°, 8°, 10°, 15°, 20° or 30°, which makes the resistance of the rotating part 200 during installation not too large and the sliding distance relatively appropriate.

[0052] As shown in Figure 4 , the installation surface 121 can also be a curved surface gradually increasing in height from one end to the other end, and the angle between the line 121c connecting the lowest end and the highest end of the curved surface on the median plane of the installation surface 121 and the bottom surface 123 of the base 100 is R, 5°≤R≤30°. Generally, the smaller the angle, the smaller the resistance during installation, but the sliding distance is also longer, and the base 100 needs to be made longer, which is high in cost. In terms of small resistance, speed and cost during installation, it is preferred that the angle be 5°, 6°, 8°, 10°, 15°, 20° or 30°, which makes the resistance of the rotating part 200 during installation not too large and the sliding distance relatively appropriate.

[0053] The bottom surface 123 of the above-mentioned base 100 is a plane, and when the base 100 is installed on the window frame 1, the surface of the base 100 that contacts the window frame 1 is the bottom surface 123 of the base 100.

[0054] As shown in Figure 5 , the installation surface 121 is provided with first blocking strips 122 on both sides, and the two first blocking strips 122 and the installation surface 121 form a strip-shaped installation groove 112. When the rotating part 200 and the base 100 are installed together, and the pivot shaft 230 needs to slide on the installation surface 121, the installation groove 112 has a guiding effect while compressing the pivot shaft 230, avoiding the pivot shaft 230 from sliding out of the installation surface 121.

[0055] A second blocking strip 111 in the shape of a U is provided around the upper part of the pivot groove 110, the U-shaped opening of the second blocking strip 111 is connected to the installation groove 112, and the two ends of the second blocking strip 111 respectively contact and connect the two first blocking strips 122. Thus, when the pivot shaft 230 slides, the pivot shaft 230 can be blocked to avoid the pivot shaft 230 from passing through the installation groove 112 due to too fast sliding.

[0056] As shown in Figure 2 , Figure 6 , Figure 7 and Figure 8, the button 220 and the pivot shaft 230 are fixedly connected to form an L-shaped structure, and the extension length of the pivot shaft 230 is greater than that of the button 220; the button 220 is provided with two fixed grooves 221 for accommodating one end of the elastic member 240, and the end of the button 220 away from the fixed grooves 221 is provided with a boss 222, so that the length of the button 220 extending out of the base body 210 is longer, facilitating the user to press the button 220.

[0057] As Figure 9 and Figure 8 , the base body 210 is provided with an accommodating groove 211, one end of the accommodating groove 211 is provided with a pivot hole 212 penetrating the base body 210, the pivot hole 212 cooperates with the pivot shaft 230, that is, the pivot shaft 230 penetrates the pivot hole 212 and cooperates with the pivot groove 110, and the other end of the accommodating groove 211 is provided with a button hole 213 for placing the button 220, the shape of the button hole 213 matches the shape of the button 220 so that the button 220 can slide in the button hole 213 in the pressing direction, that is, the button 220 is slidingly arranged in the button hole 213 to extend out of the base body 210.

[0058] As Figure 7 and Figure 10 , the bottom of the accommodating groove 211 is provided with a first limiting plate 214 and a second limiting plate 215, the first limiting plate 214 is arranged between the button hole 213 and the pivot hole 212, thereby being capable of supporting the connection between the button 220 and the pivot shaft 230, and the second limiting plate 215 is arranged at the end of the accommodating groove 211 away from the pivot hole 212, for supporting one end of the button 220, so that the button 220 can be supported and limited by the first limiting plate 214 and the second limiting plate 215.

[0059] As Figure 2 , Figure 6 , Figure 7 and Figure 11 , the top of the accommodating groove 211 is provided with a detachable cover plate 250, one end of the elastic member 240 abuts against the cover plate 250, and the other end of the elastic member 240 abuts against the button 220. In particular, the elastic member 240 can be a spring, so that the button 220 is provided with the fixed grooves 221 for accommodating one end of the elastic member 240, and oppositely, Figure 7 and 12 , the bottom of the cover plate 250 is provided with a positioning column 254, and the other end of the elastic member 240 is sleeved on the positioning column 254, so that the position of the spring can be ensured not to be skewed during installation.

[0060] The cover plate 250 and the base body 210 can be fixedly connected by bolts or screws, or can be connected by threads, and preferably are connected by buckles. Due to the small size of the hinge of the window, it is difficult to fix the cover plate 250 by screws or bolts, and it is difficult to process by threads, while the buckle is convenient to connect.

[0061] Specifically, as Figure 2 , Figure 6 , Figure 7 and Figure 11 , the buckle connection is adopted, two protruding fixing strips 216 are arranged on both sides of the top center of the accommodating groove 211, notches 2161 for placing the matching cover plate 250 are arranged at the two ends of the fixing strips 216, the entire base body 210 has four notches 2161, the cover plate 250 is provided with fixing holes 251 for accommodating the fixing strips 216; as Figure 9 and Figure 10 , the outer side of the fixing strip 216 is provided with a transversely protruding limiting portion 2162.

[0062] As Figure 11 , the outer side of the fixing hole 251 is provided with a strip-shaped gap for accommodating the limiting portion 2162, thereby one side of the fixing hole 251 forms a stepped structure, and the top surface of the limiting portion 2162 is inclined so as to be able to guide the insertion of the fixing strip 216 into the fixing hole 251.

[0063] As Figure 13 , when the cover plate 250 is completely connected with the base body 210 or before being connected: the distance between the inclined top ends of the two limiting portions 2162 is L1; the distance between the inclined bottom ends of the two limiting portions 2162 is L2; the distance between the outer side surfaces of the two limiting holes in the direction opposite to the limiting holes is L3; in order to facilitate insertion, L1 < L3, and in order to be able to be buckled after insertion, L2 > L3. Thus, when the cover plate 250 approaches the base body 210 from top to bottom, the fixing strip 216 just extends into the fixing hole 251, at this time, the inclined surface of the limiting portion 2162 has a guiding function, and the two inclined surfaces cooperate with the limiting hole to guide the insertion of the fixing strip 216 into the fixing hole 251, at this time, the two fixing strips 216 are bent and relatively close to each other by further pressing the cover plate 250, at this time, L2 is basically equal to L3, and further pressing can achieve complete buckling, when the fixing strip 216 passes through the fixing hole 251, the two fixing strips 216 return to the natural state, L2 returns to the distance value of the natural state, at this time, the limiting portion 2162 cooperates with the strip-shaped gap. In this buckling technology, the two fixing strips 216 are arranged at the top center of the accommodating groove 211, so that the two fixing strips 216 have a certain bending flexibility and can relatively close to each other by a certain distance under the action of external force.

[0064] As Figures 6-10 , in order to better install the button 220, protruding columns 217 are arranged on both sides of the end of the accommodating groove 211 away from the pivot hole 212, the button 220 is provided with guide grooves 252 matched with the protruding columns 217, and the cooperation of the protruding columns 217 and the guide grooves 252 has a guiding function and can better guide the sliding of the button 220 in the knob hole 213.

[0065] AsFigure 9 The rotating member 200 is in the shape of L as a whole, and first mounting holes 218 are arranged at two ends of the rotating member 200, and the rotating member 200 is mounted on the window through the first mounting holes 218. Figure 5 Second mounting holes 130 are arranged at two ends of the base 100, and thus the base 100 can be mounted on the window through the second mounting holes 130. Figure 5 In addition to the two second mounting holes 130 shown in the figure, V-shaped notches 219 are arranged at the sides of the mounting groove 112, and one second mounting hole 130 is arranged in each V-shaped notch 219, and there are three second mounting holes 130 in total, and in addition to one second mounting hole 130 arranged at each of the two head ends of the base 100, one second mounting hole 130 is also arranged at the middle part. This arrangement is to avoid the situation that the base 100 cannot be fixed when the window frame 1 is out of tolerance. The thickness of the window frame 1 profile is different, and some window frames 1 are relatively thin. When the base 100 is mounted on the window frame 1, the hole on the window frame 1 may become large and out of tolerance. If there are only two second mounting holes 130, it is difficult to fix the base 100 when the hole on the window frame 1 corresponding to one second mounting hole 130 is out of tolerance. Therefore, three second mounting holes 130 are arranged to be more secure.

[0066] As shown in Figure 15 and Figure 16 , the patent also discloses a quick-release and quick-mount window, which comprises a window frame 1 and a window sash 2. The bottom of the window sash 2 is connected to the window frame 1 through the above-mentioned window hinge. The base 100 is fixed to the bottom of the window frame 1 through the second mounting hole 130. The rotating member 200 is fixed to the corner at the bottom of the window sash 2. Specifically, one end of the rotating member 200 is fixed to the vertical side of the window sash 2, and the other end of the rotating member 200, i.e., the end with the button 220, is fixed to the bottom of the window sash 2. The top of the window frame 1 is provided with a rotating shaft hole, and the top of the window sash 2 is provided with an upper rotating shaft which cooperates with the rotating shaft hole. The upper rotating shaft and the pivot shaft 230 are coaxially arranged.

[0067] Therefore, when the window of the patent is disassembled, the user presses the button 220 to make the pivot shaft 230 disengage from the pivot groove 110. At this time, the user needs to hold the bottom of the window sash 2 and slightly rotate the window sash 2 outward around the upper rotating shaft. When the bottom of the window sash 2 is completely disengaged from the window frame 1, the window sash 2 can be completely removed by moving it downward. It is convenient and fast. In order to better press the button 220, the window sash 2 can be rotated at a certain angle before pressing the button 220, so that the button 220 is disengaged from the area of the window frame 1, as shown in Figures 15-17 the state. At this time, the window sash 2 rotates away from the window frame 1 at a certain angle, and the button 220 is disengaged from the area of the window frame 1. At this time, it is more convenient for the user to press the window frame 1.

[0068] In the process of installing the patent sash 2 on the window frame 1, the user holds the sash 2 and inserts the upper rotating shaft into the rotating shaft hole, then slightly rotates the sash 2 around the upper rotating shaft, so that the pivoting shaft 230 on the rotating part 200 is aligned with the installation groove 112 on the base 100, and the sash 2 is continuously slightly rotated, so that the pivoting shaft 230 contacts the installation surface 121. At this time, the user does not need to hold the sash 2, but only needs to push the sash 2 along the direction of the installation groove 112. Under the action of the installation surface 121 and the gravity of the sash 2 itself, the elastic member 240 is compressed and the pivoting shaft 230 is in a contracted state, as shown in Figure 14 At this time, the elastic member 240 is compressed and the pivoting shaft 230 is in a certain contracted state. At this time, the sash 2 is continuously pushed, and the pivoting shaft 230 of the rotating part 200 continuously slides on the installation surface 121 until the pivoting shaft 230 advances into the pivoting groove 110, that is, the installation is completed, which is convenient and fast, and no button 220 needs to be pressed during installation.
