Description

Technical Field

[0001] The utility model belongs to the technical field of window opener structures, and relates to a customized stroke structure of a three-return chain window opener. Background Art

[0002] Most commercially available chain-type window openers use a double-return chain design, which limits the window opening angle at a fixed installation length. Therefore, a three-return window opener emerged. This design increases the operating stroke by nearly 50% at the same installation length, making it more popular with users.

[0003] However, the length of the three-way window opener on the market is relatively fixed, and its installation size and maximum stroke are limited; it cannot take into account the customized needs of different users for different length requirements. Utility Model Content

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The three-way chain window opener has a customized stroke structure, including a left end cap and a right end cap arranged in parallel, and a fixed outer tube arranged between the left and right end caps, which connects and fixes the left and right end caps together.

[0006] The right end cover is provided with a turning track and a limit seat, and the left end of the fixed outer tube is provided with a chain transmission part;

[0007] A chain is provided between the chain transmission part and the turning track, one end of the chain is engaged with the chain transmission part, and the other end is engaged with the turning track;

[0008] A parallel connecting rod and a chain support tube are provided between the chain transmission part, the turning track and the limit seat; the connecting rod and the chain support tube cooperate to form a chain track, and the chain is slidably installed on the chain support tube, and the chain guide work is realized through the chain track;

[0009] The chain transmission part, the chain track, the turning track and the limit seat cooperate to form a three-circuit chain transmission structure.

[0010] As a further solution of the present invention, the connecting rod and the chain support tube are both formed by an aluminum extrusion process.

[0011] The beneficial effects of the present invention are as follows: the present application adopts a three-way chain transmission structure, which can achieve a stroke increase of nearly 50% under the same installation length; and by setting a modular outer tube structure, it can be achieved in the production process that the actual window width is matched with an outer tube of appropriate length, so that the overall window opener length is equal to the window width, achieving a consistent appearance, and the outlet wires can be hidden and screens can be added at the same time, meeting the user's processing needs for customized window opening stroke and appearance.

[0014] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. It should be understood that this application is not limited to the example embodiments disclosed herein. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0015] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0017] This utility model provides Figure 1-2 In the embodiment of the present invention, the three-way chain window opener customized stroke structure includes: a left end cover 1 and a right end cover 5 arranged in parallel, and a fixed outer tube 9 arranged between the left end cover 1 and the right end cover 5, and the left end cover 1 and the right end cover 5 are connected and fixed together by the fixed outer tube 9;

[0018] The right end cover 5 is provided with a turning track 4 and a limit seat 3, and the left end of the fixed outer tube 9 is provided with a chain transmission part 2;

[0019] A chain 6 is provided between the chain transmission part 2 and the turning track 4, one end of the chain 6 cooperates with the chain transmission part 2, and the other end cooperates with the turning track 4;

[0020] A connecting rod 7 and a chain support tube 8 arranged in parallel are provided between the chain transmission part 2, the turning track 4 and the limit seat 3; the connecting rod 7 and the chain support tube 8 cooperate to form a chain track 81, one end of the chain track 81 is connected to the exit position of the turning track 4, and the chain 6 is slidably installed on the chain support tube 8. When the chain transmission part 2 drives the chain 6 to work, the chain 6 is guided by the chain track 81 and moves along it; and a limit point 61 that cooperates with the limit seat 3 is provided in the chain 6, and the turning limit effect of the chain 6 is achieved through the limit seat 3;

[0021] The chain transmission part 2, the chain track 81, the turning track 4, and the limit seat 3 cooperate to form a three-way chain transmission structure. In actual application, the chain transmission part 2 can drive the chain 6 to be sent outward to open and close the window or to bend the tail end back into the turning track 4. The three-way chain transmission structure can achieve a nearly 50% increase in stroke under the same installation length.

[0022] Moreover, the modular outer tube structure enables the selection of different lengths of the fixed outer tube 9, connecting rod 7 and chain support tube 8 according to different window opening stroke requirements during the production process, thereby meeting the processing requirements of window opening stroke (chain moving distance) and customized appearance.

[0023] Furthermore, the connecting rod 7 and the chain support tube 8 are both formed by an aluminum extrusion process, so the overall structural strength is higher and the processable lengths are more diverse, which is more suitable for processing requirements of different lengths.
