[0028] As Figures 1 to 3As shown in the utility model discloses a kind of applied on the anti-off structure of outer opening top-hung door and window, including integrally-formed horizontal fixed arm 1 and vertical fixed arm 2, wherein the one end of horizontal fixed arm 1 is connected with the upper end of vertical fixed arm 2, the bottom surface of horizontal fixed arm 1 is equipped with bolt hole 11, vertical fixed arm 2 is integrally-formed with blocking block 21, and the blocking block 21 is equipped with positioning groove 22.

[0029] On the anti-off structure, integrally-formed horizontal fixed arm 1 and vertical fixed arm 2 are adopted, and the blocking block 21 is integrally-formed on the vertical fixed arm 2, which can make the anti-off structure itself have high structural strength. When installing and positioning, the horizontal fixed arm 1 and the vertical fixed arm 2 can be fixed, which can play the mutual limiting and strengthening effect, thereby facilitating the formation of multi-directional and multi-point limiting and strengthening effect during installation and positioning, and further facilitating the improvement of the strength of installation and positioning. During use, it can greatly reduce the probability of loosening, deformation and damage, which can help the outer opening top-hung door and window to maintain high performance for a long time, and it can help to reduce the maintenance frequency and maintenance cost of the user, which can solve the user's problem.

[0030] The positioning groove 22 is formed on the blocking block 21, which not only realizes the blocking and positioning effect, but also realizes the supporting and positioning effect, thereby facilitating the anti-off structure to have very accurate, stable and reliable anti-off effect, and further facilitating the outer opening top-hung door and window to have very good performance, which can make the anti-off structure have very high reliability and applicability.

[0031] The bolt hole 11 can be used to limit the turnover bolt on the outer opening top-hung door and window, which does not need to separately set the bolt lock seat, and when the anti-off structure has high installation and positioning strength, it can play a very stable and reliable limiting effect on the turnover bolt, which can make the suspended state of the outer opening top-hung door and window more stable.

[0032] The bolt hole 11 and the positioning groove 22 can be integrally-formed with the anti-off structure, or can be formed after the anti-off structure is formed, which can make the bolt hole 11 and the positioning groove 22 have stable and reliable positioning effect.

[0033] As shown in the utility model discloses a kind of applied on the anti-off structure of outer opening top-hung door and window, including integrally-formed horizontal fixed arm 1 and vertical fixed arm 2, wherein the one end of horizontal fixed arm 1 is connected with the upper end of vertical fixed arm 2, the bottom surface of horizontal fixed arm 1 is equipped with bolt hole 11, vertical fixed arm 2 is integrally-formed with blocking block 21, and the blocking block 21 is equipped with positioning groove 22. Figure 1 As shown, the positioning groove 22 is a notch groove formed on an upper corner of the blocking block 21. This not only facilitates manufacturing, but also facilitates the corresponding supporting mechanism to enter the positioning groove 22, thereby facilitating the positioning groove 22 to play a good positioning effect, and further helping to improve the reliability and applicability of the anti-off structure.

[0034] As shown in the utility model discloses a kind of applied on the anti-off structure of outer opening top-hung door and window, including integrally-formed horizontal fixed arm 1 and vertical fixed arm 2, wherein the one end of horizontal fixed arm 1 is connected with the upper end of vertical fixed arm 2, the bottom surface of horizontal fixed arm 1 is equipped with bolt hole 11, vertical fixed arm 2 is integrally-formed with blocking block 21, and the blocking block 21 is equipped with positioning groove 22. Figure 1As shown in the figure, the blocking block 21 is located on the side wall of the vertical fixed arm 2 towards the middle part of the horizontal fixed arm 1. This can facilitate the compact structure of the anti-falling structure, thereby facilitating the use on narrow frame, and further facilitating the improvement of the application range of the anti-falling structure. And this can also facilitate the blocking block 21 to better correspond to the direction of the upper door and window sash opening and closing, thereby facilitating the blocking block 21 to play a more accurate and stable blocking effect.

[0035] As shown in the figure, Figure 1 As shown in the figure, Figure 3 As shown in the figure, the blocking block 21 is a trapezoidal block with one end wide and the other end narrow away from the vertical fixed arm 2. This not only facilitates the forming process, but also ensures that the connection between the blocking block 21 and the vertical fixed arm 2 is very stable and reliable, thereby facilitating the blocking block 21 to play a more stable and reliable blocking effect.

[0036] As shown in the figure, Figure 1 As shown in the figure, the positioning bracket 22 includes a blocking gap 221 and an arc-shaped bracket 222. The blocking gap 221 is located on the upper corner of the blocking block 21, and the arc-shaped bracket 222 is located on the lower opening wall of the blocking gap 221, and the slot wall of the arc-shaped bracket 222 is arc-shaped transitionally connected with the opening wall of the blocking gap 221. This not only facilitates the forming process, but also facilitates the blocking block 21 and the positioning bracket 22 to play a more accurate and stable blocking and supporting effect, thereby helping to further improve the reliability and applicability of the anti-falling structure.

[0037] As shown in the figure, Figure 1 As shown in the figure, Figure 3 As shown in the figure, the vertical fixed arm 2 is integrally formed with a locking block 23, and the top of the locking block 23 is provided with a locking groove 231. This can provide a very stable and reliable locking groove 231, and the locking groove 231 can be embedded with the locking point on the door and window sash, thereby facilitating the reliable locking effect, and further helping to improve the reliability of the anti-falling structure.

[0038] As shown in the figure, Figures 1 to 4 As shown in the figure, the horizontal fixed arm 1 is integrally formed with a first hanging buckle protrusion 12, and the first hanging buckle protrusion 12 is provided with a first screw hole 121. The first screw hole 121 penetrates the first hanging buckle protrusion 12 along the hanging direction of the first hanging buckle protrusion 12, and the end of the first screw hole 121 close to the hanging buckle of the first hanging buckle protrusion 12 gradually away from the horizontal fixed arm 1. The first hanging buckle protrusion 12 can be installed by hanging, and the first screw hole 121 can be screwed with a set screw to realize the reverse clamping effect of the first hanging buckle protrusion 12 by the set screw, and the end of the set screw can be used for positioning. When a T-shaped clamping groove is formed on the inner wall of the door frame, the horizontal fixed arm 1 can be conveniently and stably fixed on the door frame, thereby facilitating the convenience and stability of installation and positioning.

[0039] like Figures 1 to 4 As shown, the first hook protrusion 12 is a horizontally extending convex strip, which enables the first hook protrusion 12 to have a more stable and reliable hooking function, thereby helping to further improve the stability and reliability of installation positioning.

[0040] like Figure 1 As shown, the horizontal fixing arm 1 is provided with a first clearance notch 122 that connects to one end of the first screw hole 121. This not only helps to control the thickness of the first hook protrusion 12, but also prevents the horizontal fixing arm 1 from affecting the wrench tool's action on the set screw screwed in the first screw hole 121, thus facilitating assembly and disassembly operations.

[0041] like Figure 1 and Figure 2 As shown, a second hook protrusion 24 is integrally formed on the vertical fixing arm 2. A second screw hole 241 is provided on the second hook protrusion 24, extending through it along the hooking direction. The screw hole 241 gradually moves away from the vertical fixing arm 2 from one end near the hooking point of the second hook protrusion 24 to the other end. The second hook protrusion 24 allows for hook installation, and the second screw hole 241 allows for the screwing of a set screw. This allows for reverse tightening of the second hook protrusion 24 by the set screw and positioning using the end of the set screw. This facilitates convenient and stable fixing of the vertical fixing arm 2 to the door frame when a T-shaped slot is provided on the inner side wall of the door frame, thereby improving the convenience and stability of installation and positioning.

[0042] like Figure 2 As shown, when the second hook protrusion 24 is provided, the end of the second hook protrusion 24 that connects with the vertical fixing arm 2 is a vertically extending protruding strip 242. This allows the protruding strip 242 to strengthen the vertical fixing arm 2, so the vertical fixing arm 2 does not need to be made too thick, and the overall structural strength is still very high. In addition, this also helps to enhance the stability and reliability of the hook positioning.

[0043] like Figure 1 As shown, the vertical fixing arm 2 is provided with a second clearance notch 243 that connects to one end of the second screw hole 241. This not only helps to control the thickness of the second hook protrusion 24, but also prevents the vertical fixing arm 2 from affecting the wrench tool's action on the set screw screwed in the second screw hole 241, thus facilitating assembly and disassembly operations.

[0044] like Figures 4 to 7As shown, the anti-falling structure of the application on the out-opening top-hung door window further comprises a supporting mechanism 3, which comprises a fixed seat 31 and an elastic swing arm 32, one end of the elastic swing arm 32 is hinged to the fixed seat 31, and the other end of the elastic swing arm 32 is directed obliquely downward, and is arranged in the positioning groove 22, and the positioning groove 22 can support the elastic swing arm 32. This not only has the effect of buffering and shock absorption, but also has the effect of stable and reliable support, so that the top-hung state of the out-opening top-hung door window is very stable and accurate, which helps to further improve the reliability and applicability of the anti-falling structure.

[0045] As shown in the drawings, Figures 4 to 7 As shown, a rubber sleeve 33 is sleeved on the other end of the elastic swing arm 32. The rubber sleeve 33 can reduce wear and tear and reduce noise, so that the use of the out-opening top-hung door window is very comfortable.

[0046] As shown in the drawings, Figures 5 to 9 As shown, a U-shaped groove 311 is formed on the outer wall of the fixed seat 31, a U-shaped spring 34 is arranged in the U-shaped groove 311, at least one side wall of the U-shaped groove 311 is provided with a gap 312, the elastic swing arm 32 is hinged to the fixed seat 31 through a hinge shaft 35, the hinge shaft 35 is located on the inner side of the middle part of the U-shaped spring 34, a pressing protruding column 321 is arranged on the inner wall of the elastic swing arm 32, and the pressing protruding column 321 can pass through the gap 312 to press the outer wall of the U-shaped spring 34 and compress the U-shaped spring 34 when the elastic swing arm 32 swings. In this way, the elastic swing arm 32 has the effect of elastic swing. A vertically extending T-shaped protruding part 313 is integrally formed on the inner wall of the fixed seat 31, a vertically penetrating gap 314 is formed on the middle part of the T-shaped protruding part 313, the gap 314 is used for the vertically sliding turnover bolt 10 to pass through, and at least one locking screw 315 is screwed on the outer wall of the fixed seat 31, and the inner end of the locking screw 315 is arranged on the inner wall of the fixed seat 31. When the fixed seat 31 is embedded on the side wall of the door leaf through the T-shaped protruding part 313, the locking effect can be achieved by pressing or embedding the locking screw 315 on the door leaf, which can conveniently and stably realize the installation and positioning of the fixed seat 31.
