[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Reference Figure 1 、 Figure 3 and Figure 4, the utility model provides an embodiment: an improved aluminum profile folding door, including a door frame 1, the left side of the inner wall of the door frame 1 is rotatably connected to the first movable door 3, the outer side of the first movable door 3 is rotatably connected to the second movable door 4, the middle part of the inner wall of the first movable door 3 is rotatably connected to a rotating rod 17, the middle part of the outer side of the rotating rod 17 is fixedly connected to a conical gear ring 6, the front side of the inner wall of the first movable door 3 is rotatably connected to a bevel gear 5, the bevel gear 5 is meshed with the conical gear ring 6, the upper and lower ends of the rotating rod 17 are fixedly connected to a threaded rod 7, the outer side of the threaded rod 7 passes through the first movable door 3 and is threadedly connected to a threaded sleeve 8, the upper and lower sides of the middle part of the inner wall of the door frame 1 are provided with fixing grooves 9, the threaded sleeve 8 is engaged with the fixing groove 9, and a positioning mechanism 2 is provided on the inner side of the second movable door 4, the positioning mechanism 2 is used to improve the sealing performance of the device;

[0040] Specifically, after rotating the bevel gear 5, the meshing transmission can drive the bevel gear ring 6 to rotate. When the bevel gear ring 6 rotates, it will cause the rotating rod 17 on it and the threaded rod 7 on the rotating rod 17 to rotate together. Since the threaded rod 7 and the threaded sleeve 8 are threadedly connected, the rotation of the threaded rod 7 will drive the threaded sleeve 8 to move. When the threaded sleeve 8 moves to the appropriate position, it will engage with the fixing groove 9. In this way, the device can be fixed by only rotating the bevel gear 5, which effectively reduces the complexity of the operation.

[0041] Reference Figure 4 and Figure 5 The positioning mechanism 2 includes a reserved groove 201, which is provided on the right side of the inner wall of the door frame 1. The upper and lower sides of the inner wall of the reserved groove 201 are provided with a card slot 205. The middle part of the inner wall of the second movable door 4 is rotatably connected to a rotating block 203. The outer side of the rotating block 203 is fixedly connected to a torsion spring 202. The outer side of the torsion spring 202 is fixedly connected to the second movable door 4. The right side of the rotating block 203 passes through the second movable door 4 and is fixedly connected to a card plate 204. The card plate 204 is engaged with the card slot 205.

[0042] Specifically, the elastic potential energy of the torsion spring 202 effectively drives the rotating block 203 to rotate. As the rotating block 203 rotates, the clamping plate 204 mounted thereon also rotates. When the device is in the closed state, the clamping plate 204 can engage with the clamping groove 205 in the reserved groove 201 during the rotation process. In this way, the device can automatically close when the door is closed, greatly improving the sealing performance of the device. Whether in preventing dust intrusion or blocking external noise, this device can play an important role in providing users with a more comfortable and quiet user experience.

[0043] Reference Figure 3 、 Figure 4 and Figure 5, the upper and lower sides of the right end of the inner wall of the door frame 1 are provided with sliding grooves 11, and the upper and lower sides of the outer wall of the second movable door 4 are rotatably connected to the running wheels 10, and the running wheels 10 are slidably connected to the sliding grooves 11; the front side of the first movable door 3 is fixedly connected to the fixing plate 12, and the inner side of the fixing plate 12 is fixedly connected to the indicator plate 13; the front right side of the first movable door 3 is rotatably connected to the knob 14, the outer side of the knob 14 passes through the first movable door 3 and is fixedly connected to the bevel gear 5;

[0044] Specifically, by opening and closing and rotating the first movable door 3 and the second movable door 4, the stability of the device during movement can be improved through the sliding of the walking wheel 10 and the slide groove 11. The indicator plate 13 in the fixed plate 12 can be used to easily provide identification and indication for the device, and the knob 14 can be used to easily drive the bevel gear 5 to rotate.

[0045] Reference Figure 1 、 Figure 2 and Figure 3 , the outer wall bottom of the door frame 1 is fixedly connected with positioning blocks 20 on all sides, and positioning holes 21 are opened on the outer side of the positioning blocks 20; the right side of the outer wall of the second movable door 4 is fixedly connected with a handle 15, and the outer side of the handle 15 is fixedly connected with a sheath 16; the upper and lower sides of the front end of the second movable door 4 are fixedly connected with hollow blocks 18, and the inner side of the hollow block 18 is slidably connected with a baffle 19;

[0046] Specifically, by installing a screw member in the positioning hole 21 on the positioning block 20, the device can be easily installed and fixed. The handle 15 and the sheath 16 thereon can be used to easily hold and open and close the second movable door 4. By moving the baffle 19 along the hollow block 18, the baffle 19 can engage the first movable door 3 and the second movable door 4 so that the two will not rotate, and the device can be switched between the folding door and the movable door.

[0047] Working principle: Before using the device, first, when the bevel gear 5 starts to rotate, the principle of meshing transmission is used to forcefully drive the bevel gear ring 6 to rotate. When the bevel gear ring 6 rotates, it will drive the rotating rod 17 and the threaded rod 7 thereon to rotate together. In this process, since the threaded rod 7 and the threaded sleeve 8 are connected by a thread, as the threaded rod 7 rotates, the threaded sleeve 8 will move along the axial direction of the threaded rod 7. When the threaded sleeve 8 moves to a specific position, it will engage with the fixing groove 9. This design is very clever. Only a simple operation of rotating the bevel gear 5 is required to fix the entire device. Compared with the traditional fixing method, this design greatly reduces the cumbersomeness of the operation, making it more convenient and efficient for the operator to perform the fixing operation, saving time and energy, while also improving work efficiency, and bringing great convenience to practical applications.

[0048] With the help of the strong elastic potential energy of the torsion spring 202, the rotating block 203 is powerfully driven to rotate. Driven by this force, the rotating block 203 rotates in a stable and orderly manner, so that the card plate 204 installed thereon rotates synchronously. When the entire device gradually closes, the card plate 204 accurately engages with the card slot 205 in the reserved slot 201 during the rotation process. The cleverness of this design is that it can enable the device to automatically close when the door is closed, greatly improving the sealing of the device. Whether in preventing dust intrusion or in blocking external noise, the device plays a vital role, bringing users a more comfortable and quiet use experience.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
