Description

Technical Field

[0001] This utility model relates to the technical field of window opener mechanism, specifically to a transmission mechanism for a hand-operated swing arm window opener. Background Technology

[0002] In the field of modern architecture, window openers, as key devices for automating or facilitating the opening and closing of windows, are widely used in various civil buildings, industrial plants, and warehousing facilities. Among them, hand-operated swing-arm window openers are widely used in various situations due to their advantages of not requiring electricity, ease of operation, and wide applicability. To achieve stable power transmission and precise window opening and closing, existing transmission mechanisms include multiple meshing gear sets, complex linkage mechanisms, and numerous auxiliary connecting parts. Some products also require specialized positioning devices and buffer structures. This complex structure not only makes assembly cumbersome but also increases production costs, resulting in relatively weak market competitiveness. Therefore, this utility model provides a transmission mechanism for a hand-operated swing-arm window opener. Utility Model Content

[0003] The purpose of this invention is to provide a transmission mechanism for a hand-operated swing arm window opener.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A transmission mechanism for a hand-operated swing arm window opener includes: The mounting base has a fixed position and internal installation space. The worm gear is rotatably mounted within the mounting space. A worm gear is rotatably disposed within the mounting space and meshes with the worm wheel, the end of the worm gear extending outside the fixed base; The swing arm has a first end that extends into the installation space through an opening communicating with the installation space and is fixedly connected to the worm gear. The second end is provided with a rotatable pulley, which slides in a groove fixedly connected to the window.

[0005] Based on the above solution and as a preferred embodiment of the above solution, the fixing base includes a mounting base, a lower cover fixedly connected to the mounting base, and an upper cover fixedly connected above the lower cover. The lower cover and the upper cover have a gap to form the installation space, and the lower cover and / or the upper cover have openings on part of their edges.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme, the end of the worm gear has a connecting part with a regular polygonal cross section for connection with the hand-cranked transmission assembly.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme, the second end of the swing arm is fixedly connected to a connecting arm perpendicular to it, and the pulley is rotatably connected to the end of the connecting arm away from the swing arm.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme, the pulley is rotatably connected to the connecting arm via a connecting rod.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme, the connecting arms are connected to both sides of the swing arm.

[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model uses a hand crank to drive a worm gear, which in turn drives a worm wheel, which in turn drives a swing arm to swing. When the swing arm swings, it works in conjunction with a sliding groove to move the window synchronously, thus opening and closing the window. This utility model has a simple structure, is easy to assemble, has low cost, and good market prospects. Attached Figure Description

[0016] 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.

[0017] like Figure 1 and Figure 2As shown, a manual rocker arm window opener transmission mechanism includes: a fixed base with a fixed position and an internal installation space. Specifically, the fixed 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.

[0018] 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.

[0019] like Figure 3 As shown, a meshing worm gear 2 and a worm 3, which can rotate in place, are arranged within the installation space. 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 portion with a regular polygonal cross-section to facilitate torque transmission.

[0020] Meanwhile, the transmission mechanism also includes a swing arm 4. The first end of the swing arm 4 extends into the mounting space through an opening communicating with the mounting space and is fixedly connected to the worm gear 2. 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.

[0021] 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.

[0022] Among them, such as Figure 4 As shown, a connecting arm 9 perpendicular to the second end of the swing arm 4 is fixedly connected, 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 connecting rod 10.

[0023] The slide 6 is fixedly connected to the edge of the window (window frame) and has a limiting protrusion to prevent the pulley 5 from disengaging.

[0024] Preferably, both sides of the swing arm 4 are connected to connecting arms 9, so that one transmission mechanism drives the opening and closing of two windows.

[0025] Working process: When the operator cranks the hand-cranked transmission component, the worm 3 rotates, the worm 3 rotates the worm wheel 2, and the worm wheel 2 rotates the swing arm 4 synchronously, causing the swing arm 4 to swing. The swing arm 4, through the cooperation of the pulley 5 and the slide groove 6, drives the window to swing synchronously, realizing the opening and closing of the window.

[0026] 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.
