Description

Technical Field

[0001] This utility model relates to the field of doors and windows, specifically to a manual window opener. Background Technology

[0002] A window opener is a device used to flexibly and efficiently control the opening and closing of windows. For example... Figure 5 As shown, the existing window opener includes a hollow housing 40 with openings at both ends, end caps 41 for closing the openings, a chain 42, and a chain drive mechanism 43. A connector 44 is installed on one end cap, which is connected to a worm gear 45 inside the housing, while the chain drive mechanism 43 is connected to the worm gear 45 via a worm wheel 46. When the user rotates the connector, the worm gear 45 rotates, driving the worm wheel 46 to rotate, which in turn drives the chain drive mechanism to rotate the chain, thereby controlling the opening and closing of the window.

[0003] When two window sashes need to be controlled simultaneously, two window openers are used and linked together by a connecting rod. During installation, the two window openers are positioned horizontally relative to each other, with the side containing the connector facing outwards. The two ends of the connecting rod are inserted into two housings 40, respectively, and engage with the corresponding worm gears 45 within those housings. Thus, simply rotating the connector 44 of one of the window openers allows simultaneous control of both window sashes. However, because the housings are relatively long and not transparent, it is difficult to accurately align the portion of the connecting rod inserted into the housing 40 with the worm gear 45, making the connection process difficult and increasing the complexity and time cost of installation. Utility Model Content

[0004] Based on this, and in response to the aforementioned technical problems, this utility model provides a manual window opener.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A manual window opener includes a housing with an internal cavity. The cavity is open at both ends. A chain and a chain drive mechanism for driving the chain are disposed within the cavity. An opening slot is provided on the side of the cavity, through which the extended end of the chain extends out of the housing. An outer end cap and an inner end cap are respectively installed at the two openings. The outer end cap has a first mounting hole, in which an outer connector is rotatably mounted. A worm gear structure connected to the chain drive mechanism is disposed within the cavity. One end of the worm in the worm gear structure is connected to the outer connector, and an inner connector is also included. A second mounting hole is provided on the inner end cap corresponding to the position of the first mounting hole, in which the inner connector is installed. The other end of the worm extends to connect with the inner connector.

[0007] In existing technologies, when two window openers need to be installed, they are linked together via a connecting rod. However, due to the long and opaque housing, inserting the connector into the housing and aligning it with the worm gear is difficult, increasing installation complexity and time costs. The aforementioned solution, however, uses an exposed inner connector rotatably mounted on the inner end cover, connected to the outer connector via a worm gear. This allows for a direct and accurate connection between the inner connectors of the two window openers via the connecting rod, significantly simplifying the installation process and reducing installation difficulty.

[0008] In a specific embodiment of this utility model: both ends of the worm gear are provided with insertion holes, the outer circumferential surface of the outer connector has a first protruding ring, dividing the outer connector into a first plug located in the receiving cavity and cooperating with the insertion hole, and a second plug extending out of the outer end cover; the outer circumferential surface of the inner connector has a second protruding ring, dividing the inner connector into a third plug located in the receiving cavity and cooperating with the insertion hole, and a fourth plug extending out of the inner end cover; during assembly, the first plug and the third plug are respectively inserted into the corresponding insertion holes.

[0009] In a specific embodiment of this utility model: all the sockets are internal hexagonal sockets, and the first plug, second plug, third plug and fourth plug are external hexagonal plugs.

[0010] In summary, this utility model rotatably mounts an external connector on the outer end cover of the housing and an internal connector on the inner end cover, with the two connectors connected by a worm gear. This allows for a direct and accurate connection between the internal connectors of the two window openers when two window openers are installed, greatly simplifying the installation process and reducing the difficulty of installation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 As shown, this utility model is a manual window opener, including a housing 10 with an internal receiving cavity 11. The receiving cavity 11 has openings 12 at both ends. An outer end cap 161 and an inner end cap 162 are respectively installed at the two openings 12. A chain 14 and a chain drive mechanism 20 for driving the chain are provided inside the receiving cavity 11. An opening slot is provided on the side of the receiving cavity 11. The protruding end of the chain 14 extends out of the housing 10 through the opening slot, while the fixed end is fixed inside the housing 10.

[0019] like Figure 1 and Figure 2 As shown, the chain drive mechanism 20 includes a sprocket 21 and a chain box 22. The sprocket 21 meshes with the chain 14, and the chain 14 is constrained into two rows within the chain box 22. The movement of the chain 14 by the rotation of the sprocket 21 is prior art, disclosed in Chinese patent CN203114003U, and will not be elaborated upon here.

[0020] like Figure 1 and Figure 3 As shown, a first mounting hole 171 is provided on the outer end cover 161. An outer connector 30 is rotatably mounted within the first mounting hole 171. Additionally, a worm gear structure connected to the chain drive mechanism 20 is provided within the receiving cavity 11. This worm gear structure includes a worm 19 and a worm wheel 25. The worm wheel 25 is coaxially fixedly connected to the sprocket 21 and meshes with the worm 19. The worm 19 is coaxially arranged with the outer connector 30. One end of the worm 19 is connected to the outer connector 30. Furthermore, an inner connector 31 is also included. A second mounting hole 172 is provided on the inner end cover 162 at a position corresponding to the first mounting hole 171. The inner connector 31 is rotatably mounted within the second mounting hole 172, and the other end of the worm 19 extends to connect with the inner connector 31. In this way, when the connector on either side is driven to rotate, it can drive the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the sprocket 21 to rotate, and then drives the chain 14 to rotate.

[0021] In this way, when two window openers need to be installed, the two window openers are linked together by a connecting rod. Since each window opener has exposed connectors at both ends, the connecting rod can be directly connected to the corresponding connectors of the two window openers, which greatly simplifies the installation steps and reduces the installation difficulty.

[0022] In this embodiment, both ends of the worm gear 19 are provided with insertion holes. A first protruding ring 301 is provided on the outer circumferential surface of the outer connector 30, dividing the outer connector 30 into a first plug 302 located in the receiving cavity 11 and mating with the insertion hole, and a second plug 303 extending outwards from the outer end cap 161. A second protruding ring 311 is provided on the outer circumferential surface of the inner connector 31, dividing the inner connector 31 into a third plug 312 located in the receiving cavity 11 and mating with the insertion hole, and a fourth plug 313 extending outwards from the inner end cap 162. During assembly, the first plug 302 and the third plug 312 are respectively inserted into their corresponding insertion holes.

[0023] In this embodiment, both sockets of the worm gear 19 are internal hexagonal sockets. The first plug 302 and the third plug 312 are external hexagonal plugs. The second plug 303 and the fourth plug 313 are external hexagonal plugs.

[0024] Window openers can be used individually or in pairs or more simultaneously. For example... Figure 4 As shown, to better illustrate this utility model, two window openers are used as an example. The housings 10 of the two window openers are respectively installed on the window frame 6 at intervals via brackets. The extended end of the chain 14 of each window opener is connected to the corresponding window sash 5. The two window openers are linked together by a connecting rod 8. The connecting rod 8 has sockets at both ends, and the fourth plugs 313 of the inner connectors of the two window openers are respectively inserted into the corresponding sockets of the connecting rod 8. Since the fourth plugs 313 of the inner connectors 31 are exposed outside the housing, the operator does not need to perform complex alignment or adjustment during installation. They can simply plug the two ends of the connecting rod 8 into the fourth plugs 313 of the two window openers to quickly and accurately achieve a connection, simplifying the installation steps and reducing the time cost required for installation. Simultaneously, because the two window openers are linked together by the connecting rod, when the outer connector of one window opener rotates, the other window opener will also perform the same action synchronously, ensuring that the windows on both sides can open or close simultaneously.

[0025] like Figure 4 As shown, the second insertion part of the outer connector 30 of one of the window openers is connected to the hand crank mechanism 7. Thus, the hand crank mechanism 7 can simultaneously control both window openers, enabling the synchronous opening or closing of the two windows. In this embodiment, the hand crank mechanism 7 consists of a rotating rod 701, a hand crank 702, and a corner mechanism 703. The hand crank mechanism consisting of the rotating rod 701, the hand crank 702, and the corner mechanism 703 is existing technology and will not be described in detail here.

[0026] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
