[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0020] like Figure 1 As shown, a hand-operated swing arm window opener includes: a fixed base with a fixed position and an internal installation space, which can be installed on the window frame or a nearby wall.

[0021] Specifically, such as Figure 4 As shown, the mounting base includes a mounting base 1, a lower cover 7 fixedly connected to the mounting base 1, and an upper cover 8 fixedly connected above the lower cover 7. The mounting base 1 is fixed to a fixed object (wall, window frame, etc.) on the side of the window. The lower cover 7 is detachably connected to the mounting base 1, and the upper cover 8 is detachably connected to the lower cover 7. Preferably, the lower cover 7 is connected to the mounting base 1 by bolts, and the upper cover 8 is connected to the lower cover 7 by bolts.

[0022] There is a gap between the lower cover 7 and the upper cover 8 to form an installation space, and openings are provided on part of the edges of the lower cover 7 and / or the upper cover 8. In this embodiment, only the edge of the upper cover 8 has an opening so that part of the installation space communicates with the outside.

[0023] The installation space contains a meshing worm gear 2 and a worm 3 that can rotate in place. The end of the worm 3 extends outside the fixed base to connect with an external hand-cranked transmission assembly. Preferably, the end of the worm 3 has a connecting section with a regular polygonal cross-section to facilitate torque transmission.

[0024] It also includes a swing arm 4, the first end of which extends into the mounting space through an opening communicating with the mounting space and is fixedly connected to the worm gear 2, and the second end is provided with a rotatable pulley 5. The swing arm 4 is fixedly connected to the side of the turbine 2 and rotates synchronously with it.

[0025] The pulley 5 slides within the groove 6, which is fixedly connected to the window. When the swing arm 4 swings, the window swings synchronously through the cooperation of the pulley 5 and the groove 6.

[0026] The second end of the swing arm 4 is fixedly connected to a connecting arm 9 perpendicular to it, and a pulley 5 is rotatably connected to the end of the connecting arm 9 away from the swing arm 4. The connecting arm 9 is detachably connected to the swing arm 4 by bolts. The pulley 5 is rotatably connected to the connecting arm 9 via a transmission rod 15. The slide groove 6 is fixedly connected to the window edge (window frame) and has a limiting protrusion to prevent the pulley 5 from disengaging. Preferably, connecting arms 9 are connected to both sides of the swing arm 4, enabling one window opener to drive the opening and closing of two windows, such as... Figure 5 As shown.

[0027] like Figure 2 and Figure 3 As shown, the window opener also includes a fixed connecting seat 10, which can be fixed to a structure such as a window frame or wall.

[0028] A connecting rod 11 is rotatably mounted inside the connecting seat 10. This connecting rod consists of a first segment located outside the connecting seat 10 and a second segment rotatably connected inside the connecting seat 10. The first segment and the second segment are interlocked and can transmit torque. Specifically, a regular polygonal through slot is formed at the center of the first segment, and a regular polygonal connecting rod portion adapted to the through slot is provided at the end of the second segment, achieving an interlocking fit. Simultaneously, the other end of the first segment is connected to the end of the worm gear 3. The worm gear 3 has a connecting portion with a regular polygonal cross-section, adapted to the aforementioned through slot, enabling the worm gear 3 to interlock with the connecting rod 11.

[0029] Meanwhile, a first gear 12 is fitted onto the second segment located inside the connecting seat 10.

[0030] A rocker arm 13 is rotatably mounted inside the connecting seat 10. The top section of the rocker arm 13 is rotatably connected inside the connecting seat 10, and the top of the rocker arm 13 is provided with a second gear 14 that meshes with the first gear 12 to realize the transmission connection between the connecting rod 11 and the rocker arm 13. The connecting rod 11 is horizontally arranged, and the rocker arm 13 is vertically arranged perpendicular to it and extends downward to a low position for easy operation by the operator.

[0031] Preferably, the rocker arm 13 has at least one bendable connecting node, allowing it to bend to meet various usage needs and improve its applicability. Specifically, in this embodiment, the segment of the rocker arm 13 located below the connecting seat 10 and near the bottom of the connecting seat 10 has a universal joint, allowing it to bend in all directions. Simultaneously, the bottom of the rocker arm 13 has two hinged bending points, meaning the bottom of the rocker arm 13 includes three sequentially hinged segments that can be bent into a Z-shape to form a rotating handle. When rotation is required, the three segments at the bottom of the rocker arm 13 are bent to form a Z-shaped handle, reducing the force required for rotation. When not in use, the three segments form a straight line, reducing space requirements.

[0032] In addition, the surface of the joystick 13 has an anti-slip structure to increase its surface friction and prevent slippage during rotation. The anti-slip structure can be a textured surface on the joystick 13.

[0033] Working process: When the operator turns the rocker arm 13, the rocker arm 13 drives the connecting rod 11 to rotate through the gear. The connecting rod 11 drives the worm gear 3 to rotate, the worm gear 3 drives the worm wheel 2 to rotate, and the worm wheel 2 drives the swing arm 4 to move synchronously, causing the swing arm 4 to swing. The swing arm 4 drives the window to swing synchronously through the cooperation of the pulley 5 and the slide groove 6, realizing the opening and closing of the window.

[0034] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
