Description

Technical Field

[0001] The utility model relates to the technical field of lifting window transmission systems, in particular to a lifting window closed-loop chain transmission system. Background Art

[0002] Electric lift windows are used for balconies or indoor windows of buildings. They control the rise and fall of windows through electric devices, allowing users to easily control the opening and closing of windows by pressing a switch or using a remote control. This design makes opening and closing windows more convenient, without the need to manually turn the window handle or pull the curtains. Electric lift windows usually use electric motors or other electric devices to achieve automatic operation, improving the comfort and convenience of users.

[0003] In order to take into account the overall sealing of the window (especially the sealing between the opening sash and the fixed sash) and the anti-fall safety issue of the opening sash, the opening sash needs to change direction and move toward the fixed sash after it is lifted up on one side of the fixed sash, so that the opening sash is placed above the fixed sash to achieve a good sealing effect between the opening sash and the fixed sash. In order to achieve the change of direction movement of the opening sash, a curved track is required. In terms of driving method, some also require both lifting and translation drives to achieve. For this reason, this case is born, providing a new opening sash transmission method. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model provides a closed-loop chain transmission system for lifting windows, such as Figure 1-4 As shown, there should be a lifting window to realize the lifting and translation of the opening leaf: including a driving mechanism, a transmission shaft and a double-chain mechanism, the double-chain mechanism is connected to the opening leaf, the driving mechanism drives the transmission shaft to rotate, and drives the double-chain mechanism to realize the lifting and translation of the opening leaf; the end of the transmission shaft can be pivoted on the side frame of the window frame. In the technical solution of this case, other components of the lifting window are not shown and are omitted, including the window frame, the lower end of the window frame can be provided with a fixed leaf, the locking mechanism and the sealing structure between the fixed leaf and the opening leaf, etc. This technical solution focuses on the new transmission system for lifting and translation of the opening leaf in the lifting window;

[0026] In the above technical solution, the double chain mechanism includes chain one and chain two. Figure 1-4 As shown, chain one is an open-loop chain, chain two is a closed-loop chain, chain one and chain two are connected in parallel, respectively meshing with drive wheel one and drive wheel two on the drive shaft, and the first and last ends of the chain are respectively connected to chain two, marked as connection point one and connection point two respectively;

[0027] The chain 1 is driven by the guide sprocket 1, the guide sprocket 2, the guide sprocket 3, the guide sprocket 4 and the transmission wheel 1;

[0028] The chain 2 is chain-driven through the guide sprocket 5, the guide chain 6 and the transmission wheel 2;

[0029] All guide sprockets in the above technical solution can be rotatably connected to the side frame of the window frame, and then the chain is engaged therewith;

[0030] The upper and lower ends of the side surface of the opening fan are respectively connected to the side surfaces of the second chain and the first chain.

[0031] The guide sprocket one and the guide sprocket two realize the horizontal transmission of the chain two, and the guide sprocket five and the guide sprocket six realize the horizontal transmission of the chain one.

[0032] The guide sprocket one and the guide sprocket five are on a vertical line.

[0033] The guide sprocket 2, the guide sprocket 6 and the guide sprocket 4 are on a vertical line.

[0034] The lower end of the opening fan is connected to one side of the chain through a connecting column.

[0035] The second chain is provided with a connecting groove, and when the door sash is opened and lifted, the connecting column is inserted into the connecting groove.

[0036] Working principle: When the closed-loop chain drive system of the lifting window is used, Figure 1 As shown, the opening sash is in the closed state. At this time, if there is a fixed sash, the opening sash should be directly above the fixed sash, thereby achieving a good sealing effect between the fixed sash and the bottom of the fixed sash to prevent the opening sash from falling, which is safer. Figure 1 As shown, after the driving mechanism is started, the driving shaft rotates, driving the transmission sprocket, and the meshing chain 1 and chain 2 are driven clockwise ( Figure 1 The opening fan moves to the right side under the action of chain 1 and chain 2 (see the left view in the figure). Figure 2 As shown), only Figure 3 The connecting column is inserted into the connecting groove. As the double chain continues to run, the opening fan moves downward along with chain one and chain two until the Figure 4 state, at this time the opening fan is in the open state to achieve ventilation. When the window needs to be closed, the driving mechanism drives the transmission shaft to rotate in the opposite direction. The step process is opposite to the opening process.

[0037] To sum up, the closed-loop chain transmission system of the lifting window realizes the synchronous transmission of chain one and chain two by setting a driving mechanism, a transmission shaft, a transmission sprocket, and chain one and chain two, thereby driving the translation and lifting of the opening leaf connected thereto, thereby realizing the conversion of the opening and closing states of the opening leaf, replacing the transmission method of using double tracks to realize the opening and closing of the opening leaf, and providing a new transmission scheme for the opening and closing of the opening leaf, which is driven by a driving mechanism, is smoother throughout the process, and saves parts.
