A limiting hole is arranged at the center inside the push-pull rod. A first spring is arranged on the top of the push-pull rod. The push-pull rod is slidably connected inside the second frame. A first chute is arranged on one side inside the second frame. By inserting the plug into the socket hole and then rotating the threaded rod to push the wedge-shaped slide rod, the push-pull rod is pushed to slide upward, thereby controlling the rotation of the movable clip through the limiting hole to fix the first frame, solving the problem that the door and window frame cannot be disassembled and installed, and achieving the effect of increasing the flexibility of the door and window frame.

[0004] However, there are still some deficiencies in the use of this patent. The door and window structure is assembled by plugging, which is likely to lead to a decline in sound insulation performance. Moreover, the construction process of plugging the door and window frames is relatively complex and requires higher skills and experience. This not only increases the construction difficulty but also may lead to cost increase. In addition, the plugging structure may have quality problems such as deformation or fracture after long-term use, and it is very inconvenient to replace. Content of the Utility Model

First cavities and second cavities are respectively formed inside the first profile body and the second profile body. First installation grooves and second installation grooves are respectively arranged at the tops of the first profile body and the second profile body. A first rubber strip is arranged between the first profile body and the second profile body. Both sides of the first rubber strip are clamped with the first profile body and the second profile body respectively. Limiting holes are formed at the tops of both the first profile body and the second profile body. A second rubber strip is arranged at the bottom of the first profile body. The two sides of the first profile body, the second profile body and the first rubber strip are all set to be 45-degree corner joints.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. In the present utility model, by setting the profile structure, the assembled angle steel sheets, the fixing bolts and the corner fitting structure, the stability and the sealing performance of the door and window frame structure are improved. By respectively inserting the corner fitting structure into the first cavity and the second cavity, and then tightening the first expansion pin and the second expansion pin to tightly connect the corner fitting structure with the two profile structures into one body, the corner connection strength is improved, and the structural stability is ensured. Compared with the insertion method, the 45-degree assembled angle splicing method can achieve a better sealing effect, enhance the corner strength and stability of the door and window, thereby ensuring the long-term stability and service life of the door and window.

Detailed Embodiment

[0023] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] For the embodiments, please refer to Figures 1-4 The present utility model provides a technical solution:

[0025] A combined door and window frame includes a profile structure 1. A corner code structure 4 is arranged on the side of the first profile body 101. The sides of two first profile bodies 101 are fixedly connected by a group angle steel sheet 2 and a fixing bolt 3. The fixing bolt 3 is threadedly connected to the side of the first profile body 101. The first expansion column 402, the first installation hole 406 and the first expansion pin 403 are concentric and coaxial. The second expansion column 407, the second installation hole 409 and the second expansion pin 408 are concentric and coaxial. The limiting hole 103 and the first installation hole 406 are concentric and coaxial. The shape of the limiting hole 103 fits the shape of the first expansion pin 403.

[0026] In this embodiment, as shown in Figure 1 、 Figure 2 and Figure 3 The profile structure 1 includes a first profile body 101 and a second profile body 102. First cavities 106 and second cavities 105 are respectively formed inside the first profile body 101 and the second profile body 102. First installation grooves 108 and second installation grooves 109 are respectively arranged at the tops of the first profile body 101 and the second profile body 102. A first rubber strip 104 is arranged between the first profile body 101 and the second profile body 102. Both sides of the first rubber strip 104 are clamped with the first profile body 101 and the second profile body 102 respectively. Limiting holes 103 are formed at the tops of both the first profile body 101 and the second profile body 102. A second rubber strip 107 is arranged at the bottom of the first profile body 101. The two sides of the first profile body 101, the second profile body 102 and the first rubber strip 104 are all set to be 45-degree corner groups.

[0027] Among them, by setting the profile structure 1, the group angle steel sheets 2, the fixing bolts 3 and the angle code structure 4, the stability and sealing performance of the door and window frame structure are improved. By respectively inserting the angle code structure 4 into the first cavity 106 and the second cavity 105, and then tightening the first expansion pin 403 and the second expansion pin 408, the angle code structure 4 is tightly connected to the two profile structures 1 as a whole, improving the corner connection strength and ensuring the structural stability. Compared with the plug-in method, the 45-degree angle splicing method can achieve a better sealing effect, enhance the corner strength and stability of the door and window, thereby ensuring the long-term stability and service life of the door and window. Moreover, the two profile structures 1 are also fixed by the group angle steel sheets 2 and the fixing bolts 3, enhancing the stability of the door and window frame.

[0028] In this embodiment, as Figure 2 and Figure 4 shown, the angle code structure 4 includes an inner angle code member 401 and an outer angle code member 404. The inner part of the inner angle code member 401 is respectively provided with a first expansion column 402 and a second expansion column 407. At the position corresponding to the first expansion column 402 on the top of the inner angle code member 401, a first installation hole 406 is opened. A first expansion pin 403 is arranged in the first expansion column 402. The first expansion pin 403 is threadedly connected to the first expansion column 402 through the limit hole 103. At the position corresponding to the second expansion column 407 on the side surface of the inner angle code member 401, a second installation hole 409 is opened. A second expansion pin 408 is arranged in the second expansion column 407. The second expansion pin 408 is threadedly connected to the second expansion column 407 through the limit hole 103 of another first profile body 101. The inner part of the outer angle code member 404 is provided with a first arc groove 405 and a second arc groove 410. The first arc groove 405 is attached to the outside of the first expansion column 402, and the second arc groove 410 is attached to the outside of the second expansion column 407.

[0029] Among them, by setting the inner angle code member 401 and the outer angle code member 404, the size of the angle code structure 4 is extended. When the cavity of the profile structure 1 is slightly larger than the angle code structure 4, the first expansion pin 403 is screwed into the first expansion column 402. The screwing-in process of the first expansion pin 403 causes the first expansion column 402 to expand, thereby causing the outer angle code member 404 to deform. Since the material of the outer angle code member 404 has good ductility, it can be expanded according to the cavity size of the profile, so that the angle code structure 4 fits the inside of the cavity of the profile structure 1, thereby improving the structural stability and strength, and the structure is simple and easy to operate.

[0030] Working process of the utility model: When a combined door and window frame designed by this solution is working, the corner code structure 4 is respectively inserted into the first cavity 106 and the second cavity 105, and then the first expansion pin 403 and the second expansion pin 408 are tightened to tightly connect the corner code structure 4 and the two sections of profile structures 1 into one body, improving the corner connection strength and ensuring the structural stability. The two sides of the profile structure 1 are set at a 45-degree corner assembly. Compared with the insertion method, the 45-degree corner assembly splicing method can achieve a better sealing effect, enhance the corner strength and stability of the door and window. When the cavity of the profile structure 1 is slightly larger than the corner code structure 4, the first expansion pin 403 is screwed towards the first expansion column 402. The screwing process of the first expansion pin 403 causes the first expansion column 402 to expand, thereby deforming the outer corner code part 404. Since the material of the outer corner code part 404 has good ductility, it can be expanded according to the cavity size of the profile, so that the inside of the corner code structure 4 and the cavity of the profile structure 1 are in close contact, thus ensuring the stability of the profile structure 1 and the corner code structure 4.

[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
