Description

Technical Field

[0001] The utility model relates to the field of window openers, in particular to a high-load-bearing double-chain window opener. Background Art

[0002] As people's living standards improve, their requirements for intelligent and comfortable living environments are getting higher and higher. Therefore, the degree of automation in homes is getting higher and higher. People often install window openers on windows to intelligently control the opening or closing of windows. Users can remotely control the windows, which is convenient and simple to use. Even if users are away from home, they can open or close windows at any time according to their needs.

[0003] The electric chain window opener is an automated window control system that uses a motor as a power source and controls the opening and closing of windows through a transmission mechanism of chains and gears. However, when the existing electric chain window opener encounters some extra-large window sashes, the chain bends and deforms during operation, resulting in a shortened service life of the electric chain window opener and unstable switching process. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a high-load-bearing double-chain window opener in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a high-load-bearing double-chain window opener, comprising a window opener box body and a chain group, the window opener box body is provided with a left chain guide and a right chain guide, the chain group comprises a left chain and a right chain respectively arranged in the left chain guide and the right chain guide, a zipper channel is provided between the left chain guide and the right chain guide for the left and right chains to simultaneously extend or retract into the window opener box body, a zipper structure that can be engaged or separated with each other is correspondingly provided between the left and right chains, a window sash connecting seat is provided at the end of the left and right chains, a wedge-shaped structural block is provided at the other end of the window opener box body corresponding to the window sash connecting seat, at least one group of driving devices is provided in the window opener box body, the driving device simultaneously drives the left and right chains to extend and retract along the zipper channel, and the engagement or separation of the left and right chains is achieved through the wedge-shaped structural block.

[0006] By adopting the above technical scheme, the driving device can be electric or manual, and the left and right chains are driven to extend and retract along the zipper channel at the same time through the driving device. A wedge-shaped structural block is set at the zipper channel to utilize two chain guides and a zipper structure to realize the synchronous extension and retraction of the chains, and the wedge-shaped structural block is used to control the engagement or separation of the extension and retraction process between the chains. When the chain retracts, the tip part of the wedge-shaped structural block transmits and amplifies the contraction force of the motor to push the engaged left and right chains apart, and when the chain is extended, the tip part of the wedge-shaped structural block also plays a guiding role to assist the left and right chains to be engaged together, thereby making the extension process of the entire chain group more labor-saving and smooth. At the same time, a special zipper-type double-chain buckled zipper structure is adopted, which can withstand heavy window sashes. Compared with the single chain structure in the prior art, it is more stable, firm, rigid, not easy to deform and bend, and has a higher bearing capacity.

[0007] The above-mentioned high-load-bearing double-chain window opener can be further configured as follows: the cross-section of the wedge-shaped structural block is triangular, the wedge-shaped structural block includes an end protrusion arranged at the center line of the zipper channel and an arc-shaped guide plate extending along the end protrusion to the left chain guide and the right chain guide on both sides, the driving device drives the left and right chains to move along the arc-shaped guide plate between the left and right chain guides and the zipper channel, and realizes the engagement or separation between the left and right chains through the end protrusion.

[0008] By adopting the above technical solution, the triangular cross-section design of the wedge-shaped structural block makes the chain more stable when engaging or disengaging, and the arc-shaped guide plate helps the chain move along a predetermined path, thereby improving the stability and reliability of the chain engaging or disengaging.

[0009] The above-mentioned high-load-bearing double-chain window opener can be further configured as follows: the left and right chains each include a plurality of groups of outer chain groups and inner chain groups that are hinged to each other, the zipper structure includes an engaging opening arranged on the outer chain group and / or the inner chain group and an engaging block corresponding to the engaging opening, and the engaging opening and the engaging block between the left and right chains are respectively engaged with each other at the zipper channel.

[0015] The above-mentioned high-load double-chain window opener can be further configured as follows: the number of the driving devices is 2, and they are respectively arranged on one side of the left chain guide and the right chain guide, and the driving devices include a motor, a sprocket meshing with the left chain or the right chain, and a gear transmission assembly arranged between the output end of the motor and the sprocket. The motors work synchronously and drive the two sprockets to rotate simultaneously through the gear transmission assembly.

[0016] By adopting the above technical solution, under this structure, two driving devices are set, and dual motors are used to drive the two left chains or the right chains to rotate respectively. The motors work synchronously to drive the two sprockets to rotate at the same time, overcoming the problems of large size, high noise ratio and high cost of a single motor required for the same load-bearing capacity, and achieving a larger load-bearing capacity.

[0017] The above-mentioned high-load-bearing double-chain window opener can be further configured as: the gear transmission assembly includes a worm arranged at the output end of the motor, a first transmission gear shaft meshing with the worm, a first gear arranged on the first transmission gear shaft, a second transmission gear shaft arranged on one side of the first transmission gear shaft and meshing with the first gear, a second gear arranged on the second transmission gear shaft, a third transmission gear shaft arranged on one side of the second transmission gear shaft and meshing with the second gear, a third gear arranged on the third transmission gear shaft, and a fourth transmission gear shaft arranged on one side of the third transmission gear shaft and meshing with the third gear; the sprocket is installed on the fourth transmission gear shaft, and drives the left and right chains to extend and retract along the zipper channel as the worm rotates.

[0022] By adopting the above technical solution, an opening is provided in the window opener box body corresponding to the zipper channel, so that the chain can be smoothly extended and connected to the window sash connecting seat, and the chain group is prevented from retracting excessively during recovery, thereby achieving a limit point.

[0023] The above-mentioned high-load-bearing double-chain window opener can be further configured as follows: the window sash connecting seat includes a connecting head for fixed connection with the window sash, a chain head connected to the left and right chains, and a rubber pad arranged in the chain head, the connecting head and the chain head are hinged to each other, and the rubber pad is arranged at one end of the chain head facing the window opener box body.
