Technical Field

[0001] This utility model belongs to the field of aluminum alloy door and window technology, and specifically relates to an aluminum alloy door and window. Background Technology

[0002] Aluminum alloy doors and windows are made using extruded aluminum alloy profiles for the frame, mullions, and sashes. They are characterized by high strength, strong corrosion resistance, resistance to deformation, light weight, and good sealing performance, and are widely used in home decoration for balconies, kitchens, bathrooms, and other spaces. Based on differences in materials and performance, aluminum alloy doors and windows can be divided into conventional aluminum alloy doors and windows and thermally broken aluminum alloy doors and windows.

[0003] However, existing aluminum alloy door and window screens are often inconvenient to install and remove. Installation and removal are time-consuming and laborious, and dust on the screen is easily blown off, making it difficult to clean the screen. Therefore, there is an urgent need for an aluminum alloy door and window to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an aluminum alloy door and window to solve the problem mentioned in the background art that the screens of existing aluminum alloy doors and windows are often inconvenient to install and disassemble, and that installation and disassembly are time-consuming and laborious.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy door and window, comprising an aluminum alloy door and window body, an outer frame, a baffle, a screen panel, a fixing structure, and a limiting structure. The aluminum alloy door and window body is slidably connected to the outer frame. The baffle is fixedly connected to the bottom front end of the outer frame. The screen panel is snapped onto the front side of the outer frame. The bottom of the screen panel is snapped between the outer frame and the baffle. The fixing structure includes fixing bolts. Grooves are provided on the front sides of both the left and right ends of the outer frame. Fixing bolts are fixedly connected to the inner walls of the grooves. The fixing bolts are rotatably connected to a limiting plate. Slots are provided on the right side and bottom of the limiting plate. The limiting structure includes a fixing rod. An installation hole is provided on the inner wall of the groove, and the fixing rod is fixedly connected to the inner wall of the installation hole. The fixing rod is slidably connected to a buckle, and the buckle snaps into the slot.

[0006] The top left and right ends of the mesh plate are provided with sliding grooves, and the shape of the sliding grooves corresponds to that of the limiting plate.

[0007] Preferably, a washer is fitted onto the fixing bolt, and the washer is located between the nut of the fixing bolt and the limiting plate.

[0008] Preferably, a lever is fixedly connected to the front side of the limiting plate, and the surface of the lever is provided with an anti-slip coating.

[0009] Preferably, a spring is fitted on the fixing rod, with one end of the spring abutting against the inner wall of the mounting hole of the groove, and the other end of the spring abutting against the outer wall of the buckle.

[0010] Preferably, the end of the buckle near the center is hemispherical, and the slot is a hemispherical groove.

[0011] Preferably, the outer wall of the buckle is fixedly connected to a limiting ring, and both the buckle and the limiting ring are slidably connected to the mounting hole of the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This aluminum alloy door and window features a fixing structure. First, the bottom of the screen panel is inserted into the gap between the outer frame and the baffle to initially fix the bottom of the screen panel. Then, the sliding groove at the top of the screen panel is aligned with the limiting plate. By rotating the limiting plate with a lever, it is turned into the sliding groove of the screen panel, thereby locking the top of the screen panel. The fixing structure makes the installation and removal of the screen panel simple and quick, without the need for tools, and facilitates the cleaning or replacement of the screen panel, reducing maintenance time and costs.

[0014] 2. This type of aluminum alloy door and window features a limiting structure. When the limiting plate rotates to the correct position, the buckle in the limiting structure automatically slides into the slot on the limiting plate under the elastic force of the spring. Since both one end of the buckle and the slot are hemispherical, the engagement is smoother and more secure, locking the limiting plate in place and preventing accidental rotation and loosening. When it is necessary to remove the screen panel, the user only needs to pull the buckle outward to overcome the spring force, causing the buckle to disengage from the slot. Then, the user can reverse the rotation of the limiting plate by turning the lever to disengage it from the sliding groove of the screen panel, thus removing the screen panel. The limiting structure uses a spring-loaded buckle that engages with the slot, ensuring that the limiting plate is not easily loosened after locking, effectively preventing the screen panel from shifting under wind pressure or vibration, and improving safety.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of an aluminum alloy door and window, comprising an aluminum alloy door and window body 1, an outer frame 2, a baffle 3, a screen 4, a fixing structure 5, and a limiting structure 6. The aluminum alloy door and window body 1 is slidably connected to the outer frame 2. The baffle 3 is fixedly connected to the bottom front end of the outer frame 2. The screen 4 is snapped onto the front side of the outer frame 2. The bottom of the screen 4 is snapped between the outer frame 2 and the baffle 3. The fixing structure 5 includes fixing bolts 51. Grooves 21 are provided on the front sides of both the left and right ends of the outer frame 2. The fixing bolts 51 are fixedly connected to the inner walls of the grooves 21. The fixing bolts 51 are rotatably connected to the limiting plate 53. The limiting plate 53 has slots 54 on its right side and bottom. The limiting structure 6 includes a fixing rod 61. The inner wall of the groove 21 has an installation hole, and the fixing rod 61 is fixedly connected to the inner wall of the installation hole. The fixing rod 61 is slidably connected to a buckle 63, and the buckle 63 snaps into the slot 54.

[0023] Furthermore, the top left and right ends of the mesh plate 4 are provided with sliding grooves, and the shape of the sliding grooves corresponds to that of the limiting plate 53. This allows the limiting plate to be smoothly screwed into the sliding grooves and fit tightly, thereby firmly locking the mesh plate from above to prevent it from coming out.

[0024] Furthermore, a washer 52 is fitted on the fixing bolt 51. The washer 52 is located between the nut of the fixing bolt 51 and the limiting plate 53. The washer can effectively reduce the frictional resistance and wear when the limiting plate rotates, and at the same time disperse the pressure to protect the surface of the parts.

[0025] Furthermore, a lever 55 is fixedly connected to the front side of the limiting plate 53. The surface of the lever 55 is provided with an anti-slip coating. The anti-slip coating increases the friction between the finger and the lever, making it easier for the user to rotate the limiting plate and less prone to slipping.

[0026] Furthermore, a spring 62 is fitted on the fixing rod 61. One end of the spring 62 abuts against the inner wall of the mounting hole in the groove 21, and the other end of the spring 62 abuts against the outer wall of the buckle 63. The spring always provides elastic force to the buckle towards the slot, ensuring that the limiting plate can be automatically locked after rotating into place.

[0027] Furthermore, the end of the buckle 63 near the center is set as a hemispherical shape, and the slot 54 is a hemispherical groove. The hemispherical contact surface allows the buckle to slide smoothly into or out of the slot, reducing movement jamming and improving the service life of the mechanism.

[0028] Furthermore, the outer wall of the buckle 63 is fixedly connected to the limiting ring 64. Both the buckle 63 and the limiting ring 64 are slidably connected to the mounting hole of the groove 21. The limiting ring can limit the sliding stroke of the buckle and prevent it from completely coming out of the mounting hole, thus ensuring the integrity and safety of the structure.

[0029] Working principle: In use, first insert the bottom of the mesh panel 4 into the gap between the outer frame 2 and the baffle 3 to initially fix the bottom of the mesh panel 4. Then, align the sliding groove on the top of the mesh panel 4 with the limiting plate 53. Rotate the limiting plate 53 by moving the lever 55 to make it rotate into the sliding groove of the mesh panel 4, thereby locking the top of the mesh panel 4. The fixing structure 5 makes the installation and removal of the mesh panel 4 simple and quick, without tools, and facilitates the cleaning or replacement of the mesh panel 4, reducing maintenance time and costs. When the limiting plate 53 is rotated to the correct position, the buckle 63 in the limiting structure 6 automatically slides into the limiting position under the elastic force of the spring 62. In the slot 54 on plate 53, since one end of buckle 63 and slot 54 are both hemispherical, the engagement is smoother and more secure, locking the limiting plate 53 in place and preventing it from accidentally rotating and loosening. When it is necessary to remove the mesh plate 4, the user only needs to pull buckle 63 outward to overcome the elastic force of spring 62, so that buckle is disengaged from slot 54. Then, the user can rotate the limiting plate 53 by turning the lever 55 in the opposite direction, so that it is disengaged from the slide of mesh plate 4, and then the mesh plate 4 can be removed. The limiting structure 6 uses buckle 63 loaded by spring 62 to cooperate with slot 54, ensuring that the limiting plate 53 is not easy to loosen after locking, effectively preventing the mesh plate 4 from shifting under wind pressure or vibration, and improving safety.
