The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] The embodiment of the present invention provides a mounting structure for a door and window auxiliary frame and a door and window outer frame, such as Figure 1-Figure 6 As shown, the installation structure of the door and window auxiliary frame and the door and window outer frame includes:

[0037] A first auxiliary frame stopper 210 and a second auxiliary frame stopper 220, wherein the first auxiliary frame stopper 210 and the second auxiliary frame stopper 220 are arranged in an auxiliary frame equipment compartment 201 provided on the door and window auxiliary frame 200, and an auxiliary frame stopper cavity 203 is also provided on the door and window auxiliary frame 200;

[0038] The first auxiliary frame limiting member 210 includes a first limiting arc block 211, a first deflection rod 212 and a guide arc rod 213. The first limiting arc block 211 is located in the auxiliary frame limiting cavity 203. The first deflection rod 212 is connected to the first limiting arc block 211 and extends into the auxiliary frame device compartment 201. The first deflection rod 212 is located in the auxiliary frame device compartment 201 and is rotatably connected to the second auxiliary frame limiting member 220 through the guide arc rod 213.

[0039] The outer frame stopper 310 is disposed in the outer frame equipment compartment 301 and the outer frame stopper cavity 304 provided on the door and window outer frame 300. The outer frame stopper 310 includes a second stopper arc block 311 and a second deflection rod 312 located in the outer frame stopper cavity 304. One end of the second deflection rod 312 extends into the outer frame stopper cavity 304.

[0040] When the door and window auxiliary frame 200 and the door and window outer frame 300 are docked, the second limiting arc block 311 and the first limiting arc block 211 are synchronously deflected and engaged in the auxiliary frame limiting cavity 203 and the outer frame limiting cavity 304. When the first limiting arc block 211 is deflected, the second auxiliary frame limiting piece 220 is driven by the guide arc rod 213 to extend into the outer frame limiting groove 320 provided on the side wall of the door and window outer frame 300. The door and window auxiliary frame 200 is provided with a limiting groove for accommodating the insertion of the door and window outer frame 300, and the limiting groove is provided on the auxiliary frame limiting cavity 203; and the door and window outer frame 300 is provided with a protruding portion inserted into the limiting groove, and the outer frame limiting cavity 304 is provided on the protruding portion. When the protruding portion is inserted into the limiting groove, the auxiliary frame limiting cavity 203 and the outer frame limiting cavity 304 are connected to each other to form a cylindrical structure;

[0041] A first connecting column 240 is provided in the auxiliary frame device compartment 201, and the first connecting column 240 is connected to the end of the first deflection rod 212 away from the first limiting arc block 211 through a spring; a second connecting column 330 is provided in the outer frame device compartment 301, and the second connecting column 330 is connected to the end of the second deflection rod 312 away from the second limiting arc block 311 through a spring.

[0042] The cross-section of the first limiting arc block 211 and the second limiting arc block 311 is a semicircular structure, and the first deflection rod 212 and the second deflection rod 312 will maintain an inclined state. During the assembly process, the protrusion is inserted back into the limiting groove, and the spring will deflect the first limiting arc block 211 and the second limiting arc block 311 to be temporarily stored in the auxiliary frame limiting cavity 203 and the outer frame limiting cavity 304 respectively. After the positions of the auxiliary frame limiting cavity 203 and the outer frame limiting cavity 304 correspond to each other, the first limiting arc block 21 1 and the second limiting arc block 311 will deflect under the action of the spring elastic force, at which time a part of the structure of the first limiting arc block 211 will extend to the outer frame limiting cavity 304, and similarly a part of the structure of the second limiting arc block 311 will also be in the auxiliary frame limiting cavity 203, completing the function of limiting locking; this structure can reduce the docking and fixing action between the door and window auxiliary frame 200 and the door and window outer frame 300, and the door and window outer frame 300 only needs to be engaged with the inner edge of the door and window auxiliary frame 200 in the corresponding direction to complete the assembly;

[0043] The second auxiliary frame stopper 220 will perform secondary locking on the door and window outer frame 300 under the linkage action of the first auxiliary frame stopper 210;

[0044] It should be noted here that the lengths of the limiting groove and the protruding portion are respectively equal to the lengths of the side lengths of the door and window auxiliary frame 200 and the door and window outer frame 300, and the auxiliary frame equipment compartment 201, the auxiliary frame limiting cavity 203, the first auxiliary frame limiting member 210 and the second auxiliary frame limiting member 220 constitute an independent main locking module, which is spaced apart on the limiting groove. Similarly, the outer frame equipment compartment 301, the outer frame limiting cavity 304, the outer frame limiting member 310 and the outer frame limiting groove 320 constitute an independent secondary locking module, which is also correspondingly arranged on the protruding portion; the lengths of the main locking module and the secondary locking module are only a section of the side lengths of the door and window auxiliary frame 200 and the door and window outer frame 300;

[0045] As a preferred implementation in this embodiment, the second auxiliary frame limiting member 220 includes a sliding plate 221, a guide slider 222 and a limiting guide rail 223, the sliding plate 221 is connected to the guide slider 222, and the guide slider 222 slides along the limiting guide rail 223;

[0048] In this embodiment, after the protrusion is inserted into the limiting groove, the first limiting arc block 211 will be pressed back into the auxiliary frame limiting cavity 203 first; the position of the limiting block 2113 here needs to ensure that the outer frame limiting groove 320 reaches the vicinity of the limiting block 2113 after the first limiting arc block 211 is pressed back into the auxiliary frame limiting cavity 203. When the first limiting arc block 211 loses the pressing of the protrusion, the limiting block 2113 is synchronously inserted into the outer frame limiting groove 320;

[0050] In this embodiment, the width of the first limiting arc plate 214 is greater than the width of the sliding guide groove, and the first limiting arc plate 214 can be used to help the first limiting arc block 211 to perform positioning and guidance, so that the first limiting arc block 211 can only perform circular motion in the auxiliary frame limiting cavity 203; the second deflection rod 312 is also provided with a second limiting arc plate 313, and the second deflection rod 312 is not provided with a guide arc rod 213 to drive other limiting devices, and the other structural movement principles of the outer frame limiting member 310 are basically the same as those of the first auxiliary frame limiting member 210, which will not be described in detail here;
