Detailed Description

The invention is further described with reference to the following figures and specific embodiments.

As shown in fig. 1 to 5, the horizontal pushing window opener of the present embodiment includes a housing 1 adapted to be fixed or bonded to a window inner frame by a suction cup, a motor 4 (stepping motor) fixed in the housing 1, a controller for controlling the motor 4, a screw rod 2 driven by the motor 4, a slider 3 disposed on the screw rod 2 by a threaded connection, a drum 9 hinged to the slider 3, and a rack 8 vertically disposed in the middle of the housing. The upper half part and the lower half part of the shell 1 are provided with a first telescopic rod 6 and a second telescopic rod 7 which can respectively extend towards two sides, the first telescopic rod 6 and the second telescopic rod 7 are unequal-arm scissor structures formed by hinging scissor arms, the length of each section of the scissor structure is unequal, the ratio from outside to inside is 1:2:4, and the main purpose is to increase the force for pushing the telescopic rods (6 and 7) through the change of torque. The first and second

telescopic rods

6, 7 have outer ends for pushing the inner window frame 12 or the outer window frame 11, fixed ends hinged to the housing 1, and movable ends vertically slidable within the housing 1. When the expansion end pressed to the stiff end, the telescopic link was released, when the expansion end kept away from the stiff end, the telescopic link was withdrawed. The movable ends of the first and second

telescopic rods

6, 7 have an F-shaped dog 10, and the drum 9 has an opening 14 suitable for the insertion of the F-shaped dog 10. Specifically, as shown in fig. 5, the opening of the drum 9 is adapted to slide into the gap between the upper and lower arms of the F-shaped lever from the side, thereby achieving the connection between the F-shaped lever and the drum 9.

The back of the drum 9 has teeth 13 that engage with the rack 8. Through the cooperation of the rack 8 and the teeth 13, the hook and the unhook between the F-shaped deflector rod 10 and the rotary drum 9 in the moving process of the sliding block are realized, and the clutch between the F-shaped deflector rod and the rotary drum is skillfully realized.

In this example, a sliding rod parallel to the screw 2 is fixed in the housing 1, the movable ends of the sliding block 3, the first telescopic rod 6 and the second telescopic rod 7 are slidably arranged on the sliding rod, and the fixed ends of the first telescopic rod 6 and the second telescopic rod 7 are hinged with the sliding rod. Alternatively, a longitudinal slide may be provided in the housing 1, and the movable ends of the slider 3, the first telescopic rod 6 and the second telescopic rod 7 are provided with protrusions embedded in the slide so that they can slide up and down along the slide, and the fixed ends of the first telescopic rod 6 and the second telescopic rod 7 are directly hinged to the housing 1 or a fixed part fixed in the housing 1.

Specifically, in the process that the sliding block 3 is moved to enable the teeth 13 on the back of the rotary drum 9 to be separated from the rack 8, the F-shaped deflector rod 10 slides into the opening 14 of the rotary drum 9 and is limited, and after the rotary drum 9 is completely separated from the rack 8, the rotary drum 9 pushes and pulls the movable end of the telescopic rod through the F-shaped deflector rod 10, so that the telescopic rod is driven to be pushed out or retracted; during the process of moving the sliding block 3 to enable the teeth 13 at the back of the rotary drum 9 to be meshed with the rack 8, the F-shaped shifting rod 10 at the movable end slides out of the opening 14 of the rotary drum 9, and the rotary drum 9 is separated from the telescopic rod.

As shown in fig. 1, the window opening process is schematically illustrated, at this time, the sliding block 3 is sliding downward, the rotating drum 9 has been separated from the rack 8, the rotating drum 9 and the F-shaped shift lever at the movable end of the second telescopic rod 7 are clamped together, and the sliding block 3 is continuously pushed downward, so that the window is continuously opened. After the window is opened to the maximum, the second telescopic rod 7 can be retracted. When the second telescopic rod 7 needs to be retracted, the motor 4 drives the screw rod 2 to rotate reversely, so that the sliding block 3 moves upwards. At this time, since the F-shaped shift lever at the movable end of the second telescopic rod 7 is clamped together, the slide block 3 drives the movable end of the second telescopic rod 7 to move upwards, so that the second telescopic rod 7 is retracted. When the second telescopic rod 7 is fully retracted, the teeth 13 at the back of the drum 9 start to engage with the toothed rack 8. The sliding block 3 continues to move upwards, the rotary drum 9 starts to rotate anticlockwise, the F-shaped shifting rod 10 at the movable end slides out of the opening 14 of the rotary drum 9, and the sliding block 3 is unhooked from the second telescopic rod 7. When the window needs to be closed, the sliding block 3 continues to move upwards, so that the F-shaped shifting rod at the movable end of the first telescopic rod 6 is clamped into the rotary drum 9, and then the sliding block 3 pushes and pulls the movable end of the first telescopic rod 6 through the hook between the two. When the slide block continues to move upwards, the first telescopic rod 6 extends rightwards (as shown in fig. 2), and the window is closed.

In this embodiment, the drum 9 is hingedly connected to the slide 3 in a damped manner, so that the drum 9 only moves in translation after the teeth on the back of the drum 9 have disengaged from the rack. The output head of the motor 4 is connected with the screw rod 2 through a coupler 5. The outer ends of the first telescopic rod 6 and the second telescopic rod 7 are provided with idler wheels, so that in the lifting and retracting rod pushing process, the outer ends of the telescopic rods can slide on the outer window frame 11 or the inner window frame 12, and the telescopic rods cannot be locked.

In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
