Therefore, the degree of home automation 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 when users are away from home, they can open or close windows at any time according to their needs.

[0003] The existing Chinese utility model patent with announcement number CN220451667U discloses a chain quick plug-in device for a window opener, wherein a quick-connect plug-in block is arranged at the end of the window opener driving component, and a quick-connect socket and an elastic locking mechanism are arranged on the window sash connector. When the quick-connect plug-in block enters the quick-connect slot, the latch moves backward and disengages from the quick-connect slot as the quick-connect plug-in block enters, overcoming the elastic force of the spring, and then is inserted into the socket of the quick-connect plug-in block after being reset by the action of the spring, locking the quick-connect plug-in block in the quick-connect slot to achieve quick plug-in. However, in actual use, the structure is complex and costly, and when in use, the user needs to continuously press the unlocking plate to overcome the elastic force of the spring in order to remove or install the chain, which results in the user having to exert force all the time to control the insertion and removal of the chain, which is very laborious. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a chain head quick-connect structure for a chain-type window opener in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chain head quick-connect structure for a chain-type window opener, comprising a window sash connector and a chain with a socket, the window sash connector comprising a mounting shell for fixing on the window sash, a quick-connect slot provided in the mounting shell for the chain to access, and at least one toggle baffle arranged at the corresponding quick-connect slot in the mounting shell, characterized in that: the toggle baffle is hinged to the mounting shell through a pin shaft, and a locking portion that cooperates with the socket is provided at one end of the toggle baffle facing the quick-connect slot, the toggle baffle rotates along the pin shaft to thereby move the locking portion into or out of the quick-connect slot, and a baffle locking mechanism is provided between the mounting shell and the toggle baffle to limit the rotation of the toggle baffle after the locking portion enters the quick-connect slot.

[0006] By adopting the above technical solution, when installing or removing the chain, the user only needs to drive the toggle baffle to rotate the toggle baffle along the pin shaft to disengage the locking part from the quick-connect slot, so that the chain can be disengaged or connected. After the chain enters the quick-connect slot, it is only necessary to drive the toggle baffle again to make the locking part enter the socket, and the toggle baffle will also be locked by the baffle locking mechanism to avoid it from falling out during use. The entire structure simplifies the structure and reduces the cost by designing the toggle baffle, locking part and baffle locking mechanism in the window sash connector, making the chain installation process simpler and faster. The user does not need to continuously press the unlocking plate with force, but only needs to simply toggle to achieve quick installation of the chain, which greatly reduces the user's operating burden.

[0007] The above-mentioned chain head quick-connect structure for the chain-type window opener can be further configured as follows: the baffle locking mechanism includes a ball-shaped top screw arranged on the mounting shell and a locking groove arranged on the toggle baffle and correspondingly engaged with the ball-shaped top screw, the ball-shaped top screw includes a top screw body, an elastic member arranged in the top screw body and a ball arranged at the end of the top screw body, the ball is abutted against the elastic member and is telescopically arranged in the top screw body, the top screw body is installed on the mounting shell, and the ball telescopically arranged on the top faces the direction of the toggle baffle, and when the locking portion enters the quick-connect slot, the ball is engaged in the locking groove of the toggle baffle.

[0008] The above technical solution adopts the coordinated design of the ball-end screw and the locking groove, which avoids the tedious operation of continuously overcoming the spring elastic force in the traditional structure. The ball-end screw can easily achieve engagement and separation with the locking groove without the user having to exert continuous force, thereby improving installation efficiency and reducing operating difficulty.

[0009] The above-mentioned chain head quick-connect structure for the chain-type window opener can be further configured as follows: the locking groove is a circular groove adapted to the ball, and the edge is provided with a chamfer whose diameter gradually decreases toward the inner circle.

[0010] By adopting the above technical solution, the circular groove and chamfer design of the locking groove optimize the matching relationship between the ball and the locking groove, improve the stability and reliability of the snap connection, and make the ball enter or leave the locking groove more smoothly.

[0011] The above-mentioned chain head quick-connect structure for the chain-type window opener can be further configured as follows: the outside of the top screw body is provided with threads, and the top screw body is installed on the installation shell through the threads.

[0012] By adopting the above technical solution, the top screw body is installed with threads, which is not only convenient for disassembly and maintenance, but also improves the stability of the installation. This design avoids the performance degradation problem caused by loose installation. At the same time, the ball-type top screw can be replaced separately after it is worn, thereby increasing the service life of the product.

[0013] The above-mentioned chain head quick-connect structure for the chain-type window opener can be further configured as follows: the number of the toggle baffle and the baffle locking mechanism is 2, and they are symmetrically arranged at both ends of the quick-connect slot.

[0014] By adopting the above technical solution, the stability and reliability of chain installation are further enhanced by providing two sets of symmetrical toggle baffles and baffle locking mechanisms. This design effectively prevents safety problems caused by failure of a single component and improves the overall performance of the product.

[0015] The above-mentioned chain head quick-connect structure for the chain-type window opener can be further configured as follows: a toggle portion is provided at one end of the toggle baffle away from the locking portion, and when the locking portion enters the quick-connect slot, the toggle portion extends out of the mounting shell.

[0016] By adopting the above technical solution, the toggle part extends out of the installation shell, so that when inserting or disengaging the chain head, the outer toggle part can be directly pulled, which is convenient for users to quickly identify and operate, and improves the accuracy and convenience of installation.

[0017] The above-mentioned chain head quick-connect structure for the chain-type window opener can be further configured as follows: a limit platform is provided at one end of the mounting shell away from the quick-connect slot, and when the locking portion enters the quick-connect slot, the toggle baffle abuts against the limit platform, and the toggle baffle is accommodated in the mounting shell, and the toggle portion extends out of the limit platform.

[0018] By adopting the above technical solution, by setting a limit table, after the locking part is fixed, it is possible to quickly judge whether the chain installation and fixation are completed directly through the limit table, and limit the rotation of the toggle blocking piece to avoid excessive operation.

[0019] The above-mentioned chain head quick-connect structure for the chain-type window opener can be further configured as follows: the toggle portion is a hook-shaped structure, and the outer surface is an arc chamfered structure.

[0020] By adopting the above technical solution, the chamfered shape design of the hook makes the toggle block easier to be moved by the fingers, and helps to reduce friction, making the operation smoother and easier. The hook design can also increase the contact area between the manual shift block and the operating part, increase friction, thereby preventing slippage during operation, and improve the durability of the toggle block. This design can reduce stress concentration and reduce the risk of breakage or deformation of the shift block during long-term use.

[0021] The above-mentioned chain head quick-connect structure for the chain-type window opener can be further configured as follows: the mounting shell includes a first window sash mounting hole arranged at the bottom and / or a second window sash mounting hole arranged at the side of the mounting shell.

[0022] By adopting the above technical solution and the porous design of the mounting shell, the product can adapt to different installation environments and requirements.
