[0001] The utility model belongs to the technical field of aluminum alloy doors and windows, in particular to an opening and closing angle controller for an aluminum alloy door and window. Background Art

[0002] The aluminum alloy door and window opening and closing angle controller is an accessory installed on aluminum alloy doors and windows. By adjusting its internal mechanism, the opening and closing angle of the doors and windows can be controlled to meet the different needs of users. This controller is usually installed on the hinges or sliding rails of doors and windows, and the opening and closing angle of the doors and windows can be controlled by adjusting the strength of the screws or springs.

[0003] Traditional aluminum alloy doors and windows usually use fixing devices such as hinges and slide rails to achieve the opening and closing of doors and windows. However, such fixing devices usually only provide basic opening and closing functions and cannot meet the user's personalized needs for the opening and closing angles of doors and windows. When users need to adjust the opening and closing angles of doors and windows, they usually need to use additional tools or manually fix or adjust them. The operation is relatively complicated and lacks flexibility. It cannot adapt to various usage scenarios and is not convenient for accurately adjusting the opening and closing angles of doors and windows. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides an aluminum alloy door and window opening and closing angle controller.

[0020] 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.

[0021] like Figures 1 to 4 As shown, the utility model provides an aluminum alloy door and window opening and closing angle controller, comprising a first positioning plate 1, a lock buckle 2 is fixedly installed on the top of the first positioning plate 1, a fixing rope 3 is installed at one end of the lock buckle 2, and a winding mechanism 4 is installed at one end of the fixing rope 3;

[0022] The winding mechanism 4 includes a storage roller 41, a storage bin 42 and a limit member 43. The bottom surface of the storage roller 41 is fixedly connected to a rotating shaft 44, the bottom end of the rotating shaft 44 is rotatably connected to the inner wall of the storage bin 42, and the limit member 43 is arranged on one side of the storage bin 42.

[0023] The above scheme is adopted: the first positioning plate 1 serves as the basic component, providing a stable installation platform for the lock buckle 2, and the first protective film 101 bonded to its bottom surface can protect the surface of the first positioning plate 1 from damage such as scratches and corrosion. The lock buckle 2 is a key component for connecting with the fixing rope 3. The key operation can realize the fixation or unlocking of one end of the fixing rope 3 and the lock buckle 2, thereby facilitating the restraint or release of related items, and plays an important role in some scenarios where it is necessary to temporarily fix or restrict the movement of the position of items.

[0024] like Figures 1 to 4 As shown, the bottom surface of the first positioning plate 1 is bonded with a first protective film 101, and the lock buckle 2 can fix one end of the fixing rope 3 to the lock buckle 2 through a key. The bottom surface of the winding mechanism 4 is fixedly connected with the second positioning plate 5, and the bottom surface of the second positioning plate 5 is bonded with a second protective film 51, and the size of the second protective film 51 is adapted to the size of the second positioning plate 5. The fixing rope 3 is wound around the surface of the storage roller 41, and the top of the storage bin 42 is clamped with a dust cover 6, which is made of transparent material, and the top surface of the storage bin 42 is provided with a clamping hole for limiting the dust cover 6.

[0025] The above scheme is adopted: the fixing rope 3 can limit the article with the cooperation of the lock buckle 2, one end of which is connected to the lock buckle 2, and the other end is connected to the winding mechanism 4. The storage roller 41 in the winding mechanism 4 is used to wind the fixing rope 3, and is rotatably connected to the inner wall of the storage bin 42 through the rotating shaft 44, so that the storage roller 41 can rotate flexibly, which is convenient for releasing or retracting the fixing rope 3 when using the fixing rope 3. The storage bin 42 provides a relatively closed protective space for the storage roller 41, the rotating shaft 44 and related components to prevent external dust, debris, etc. from interfering with and damaging the internal components. The dust cover 6 clamped on the top is made of transparent material, which can effectively prevent dust from entering the storage bin 42, and can also facilitate the user to observe the winding status of the fixing rope 3 in the storage bin 42 and the value of the rotation counter 45 and other information. The clamping hole ensures the stable installation and limitation of the dust cover 6 on the top of the storage bin 42.

[0026] like Figures 1 to 4 As shown, the dust cover 6 and the storage bin 42 are both provided with a limiting groove on one side close to the limiting member 43, and the limiting groove is used for the movement of the limiting member 43. The outer surface of the storage bin 42 is fixedly connected with a fixed block 421. The limiting member 43 includes a threaded rod 431 and an abutment plate 432. One end of the threaded rod 431 is threadedly connected to the inner wall of the fixed block 421, and the other end of the threaded rod 431 is rotatably connected to the abutment plate 432 through a bearing. The abutment plate 432 is abutted against the top surface of the storage roller 41 through the driving energy of the threaded rod 431, and the top surface of the storage roller 41 is fixedly connected with a rotation counter 45.

[0027] The above scheme is adopted: the limiting member 43 includes a threaded rod 431 and an abutment plate 432, one end of the threaded rod 431 is threadedly connected to the inner wall of the fixed block 421, and the length of its extension in the fixed block 421 can be accurately controlled by rotating the threaded rod 431, and the abutment plate 432 is rotatably connected to the other end of the threaded rod 431 through a bearing. In this way, when the threaded rod 431 rotates, the abutment plate 432 can maintain a relatively stable posture. When the abutment plate 432 abuts against the top surface of the storage roller 41 under the drive of the threaded rod 431, it can apply friction to the storage roller 41 to limit its rotation, so that the fixing rope 3 can be kept fixed at the required length, and the fixing rope 3 will not be loosened or over-reeled due to the free rotation of the storage roller 41.

[0028] The working principle and usage process of the present invention are as follows: First, in the initial state, the fixing rope 3 is wound around the storage roller 41, and the dust cover 6 is clamped on the top of the storage bin 42 to protect the internal components. If the device is to be used to fix items, the first positioning plate 1 is first placed at a suitable position on the door or window, and the first protective film 101 on its bottom surface is uncovered, so that the first positioning plate 1 can be connected to the door or window. Next, one end of the fixing rope 3 is taken out, and this end of the fixing rope 3 is operated with the key to lock the buckle 2 so that it is tightly fixed to the buckle 2. Then, the second protective film 51 is uncovered, and the second positioning plate 5 is fixed to another suitable position on the door or window.

[0029] When the length of the fixing rope 3 needs to be adjusted, the threaded rod 431 in the limiter 43 is rotated according to actual needs. If the fixing rope 3 needs to be released, the threaded rod 431 is rotated outward to separate the abutment plate 432 from the top surface of the storage roller 41 or to reduce the friction. At this time, the fixing rope 3 can be pulled, and the storage roller 41 rotates as the fixing rope 3 is pulled out. The fixing rope 3 is gradually released, and the rotation counter 45 on the top surface of the storage roller 41 records the rotation data so that the user knows the released length. The threaded rod 431 is rotated in the opposite direction to make the abutment plate 432 tightly abut against the top surface of the storage roller 41 and generate appropriate friction.

[0030] During the entire use process, the storage bin 42 provides a stable installation and protection space for the storage roller 41 and the rotating shaft 44. The fixed block 421 on its outer surface provides support and connection basis for the limit member 43. The dust cover 6 can prevent dust from entering the storage bin 42 and affecting the operation of internal components. Its limit groove cooperates with the limit groove of the storage bin 42 to ensure that the limit member 43 moves within the prescribed path. The second positioning plate 5 provides another support point for the winding mechanism 4, and the second protective film 51 on its bottom surface protects the second positioning plate 5.
