Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to an automatic door and window pulley assembly. Background Art

[0002] With the acceleration of urbanization and the continuous improvement of people's quality of life, modern building technology has entered a new stage. In this stage, the automatic door and window system, as an important part of building intelligence, is gradually becoming an indispensable part of commercial and residential buildings. It not only provides a convenient way to open and close, but also brings great convenience and comfort to users through its intelligent electronic control device. The pulley assembly is one of the important parts of automatic doors and windows, which can reduce the friction between the doors and windows and the track during the opening and closing process, making the operation smoother and easier.

[0003] Although the popularity of automatic doors and windows has improved the level of modernization of buildings, it has also brought some problems. One of the main problems is the impact of debris on the track on the operation of doors and windows. In actual use, various debris often appear on the track, such as paper, bottle caps, small tools, etc. At the same time, indoor and outdoor air flow, as well as fine particles generated during building decoration, may also leave deposits on the door and window tracks. These tiny but not negligible deposits may gradually accumulate and pose a threat to the normal operation of doors and windows.

[0004] Existing automatic door and window pulley assemblies often lack the ability to handle debris on the track. When the door or window moves according to instructions, if there is debris on the track, the pulley assembly will often continue to operate and collide with the debris. This collision may cause the pulley assembly to derail or become damaged, thus affecting the normal operation of the door or window. In extreme cases, the door or window may even fall off, causing personal injury or property damage. Utility Model Content

[0005] The utility model aims to provide an automatic door and window pulley assembly, which can automatically adjust the gap between the pulley body and the track when an obstacle appears on the door and window track, so as to cross the obstacle and avoid forced collision with the obstacle, thereby effectively preventing the door and window from derailing or the pulley body and the track from being damaged.

[0006] The technical solution adopted by the utility model is as follows:

[0017] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0018] like Figure 1-4 As shown, an automatic door and window pulley assembly includes a U-shaped plate 1, and at least two mounting holes are arranged on the plate, so that the plate can be easily fixed at the designated position of the door and window by bolts. In addition, an adaptive pulley mechanism is installed inside the plate, and the adaptive pulley mechanism includes a round rod 2 fixed at the middle position of the inner side of the U-shaped plate 1, a rotation groove is opened on the outer side of the round rod 2, a round tube 3 is installed in the rotation groove on the outer side of the round rod 2, and the round tube 3 is rotatably connected to the round rod 2 through the setting of the rotation groove, and connecting blocks 12 are fixed on both sides of one end of the round tube 3, and a rectangular plate 4 is fixed on the connecting block 12;

[0019] See attached Figure 3 and attached Figure 4 A slider 5 is installed inside the rectangular plate 4, and a slide groove adapted to the slider 5 is opened inside the rectangular plate 4. The slider 5 is located in the slide groove inside the rectangular plate 4. The rectangular plate 4 and the slider 5 are slidably connected by setting the slide groove. An elastic column 6 is installed on the top of the slider 5, and the elastic column 6 is located in the slide groove inside the rectangular plate 4. A connecting plate 7 is fixed to the bottom of the slider 5. A sliding hole adapted to the connecting plate 7 is opened at the bottom of the rectangular plate 4. The sliding hole and the slide groove are communicated, and the connecting plate 7 and the rectangular plate 4 are connected by the slideway set by the sliding hole;

[0020] A round block 8 is fixed to the bottom of the connecting plate 7, and a pulley body 9 is rotatably connected to one side of the round block 8. In order to enhance the wear resistance of the pulley body 9 and extend its service life, a polyurethane coating is coated on the outer side of the pulley body 9.

[0021] According to the above structure, before use, the U-shaped plate 1 is fixed to a designated position on the door or window, so that the pulley body 9 is aligned with the track of the door or window, ensuring that the pulley body 9 can move smoothly on the track;

[0022] When doors and windows are in use, dust and particles from both inside and outside the room may flow into the room with the air, and some of them may settle on the door and window tracks. In addition, decoration or construction projects may generate dust and particles, which may also fall on the tracks. Sometimes, people may leave items on the tracks.

[0023] When the doors and windows move automatically, one of the pulley bodies 9 first contacts with impurities, foreign objects, etc. on the track, which causes the elastic column 6 on one of the pulley bodies 9 to deform under force, so that one of the pulley bodies 9 can rise and leave the track to achieve obstacle crossing capability, while the other pulley body 9 remains in contact with the track to prevent the doors and windows from derailing.

[0024] When the impurities and foreign objects on the track are large, one of the pulley bodies 9 contacts the impurities in advance, causing the two elastic columns 6 to deform. At the same time, one of the pulley bodies 9 tilts up, while the other pulley body 9 maintains close contact with the track, thereby improving the obstacle crossing capability.

[0025] Therefore, when an obstacle appears on the door and window track, the pulley body 9 can automatically adjust the gap between the track and the obstacle to cross the obstacle and avoid forced collision with the obstacle, thereby effectively preventing the door and window from derailing or the pulley body 9 and the track from being damaged. This not only ensures the safety and stability of the door and window, but also greatly prolongs the service life of the pulley body 9 and the slide rail.

[0026] See attached Figure 2 , the only difference between this embodiment and embodiment 1 is that an obstacle warning component is also installed on the inner side of the U-shaped plate 1;

[0027] The obstacle warning component includes two wireless pressure sensors 10 fixed on the inner side of the U-shaped plate 1. The two wireless pressure sensors 10 are respectively located above the two round blocks 8. An elastic strip 11 is installed on the wireless pressure sensor 10. The end of the elastic strip 11 away from the wireless pressure sensor 10 is fixedly connected to the round block 8.

[0028] The wireless pressure sensor 10 is an existing mature technology, which includes components such as a sensor element, a signal conditioning circuit, a wireless communication module and a power module;

[0029] The elastic strip 11 is connected to the sensor element on the wireless pressure sensor 10, and the wireless communication module is wirelessly connected to the electric controller on the electric door and window. When in use, it can be debugged, and it will not be described in detail in this embodiment;

[0030] According to the above structure, when the door and window move automatically, if there are impurities on the track causing the pulley body 9 to be displaced, tilted or raised, the wireless pressure sensor 10 can sense the pressure change through the elastic strip 11 and send a warning signal to the electric controller of the door and window. After receiving the warning signal, the electric controller will stop the movement of the door and window to avoid the door and window being damaged or falling off due to obstacles.

[0031] Therefore, the device can be connected to the electric controller of doors and windows to realize intelligent management and monitoring functions. Once the pulley body 9 contacts with foreign objects or an abnormal situation occurs, a warning signal will be immediately transmitted to the electric controller so that necessary measures can be taken in time, such as stopping operation. This further improves the safety and reliability of the door and window system.

[0032] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified or limited.
