Description

Technical Field

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

[0002] A double-chain window opener is a device used to control the opening of doors and windows. To open the window, the motor starts and rotates the chain, whose pull gradually opens the window. Once the window reaches the desired position, the motor stops, and the chain holds the window open.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] Example 1:

[0052] like Figures 1 to 5 As shown, the utility model provides a double-chain window opener, comprising: a double-chain window opener 1 and a window opening chain 2 movably mounted on the double-chain window opener 1 for supporting and opening and closing windows.

[0053] In order to make the window opening chain 2 smoother during operation and to facilitate the lubrication operation of the window opening chain 2, a lubrication structure for lubricating the window opening chain 2 is arranged on one side of the double-chain window opener 1. The lubrication structure includes a storage structure for storing lubricating oil and a control structure for controlling the flow of lubricating oil to the window opening chain 2.

[0054] Among them, the storage structure includes a lubricating oil box 3 for storing lubricating oil, a guide pipe 301 arranged below the lubricating oil box 3 and connected to the lubricating oil box 3 for discharging the lubricating oil, a ring frame 302 arranged on the guide pipe 301, and a fixing frame 303 arranged on the ring frame 302 and the double-chain window opener 1 for supporting the ring frame 302. The guide pipe 301 is located above the window opening chain 2, and the window opening chain 2 is located inside the ring frame 302. Lubricating oil is added to the lubricating oil box 3, so that the lubricating oil flows into the guide pipe 301, and then flows to the window opening chain 2 through the guide pipe 301.

[0055] Among them, the control structure includes a linkage shaft 304 rotatably installed inside the guide tube 301, a motor 305 arranged on the double-chain window opener 1 for driving the linkage shaft 304 to rotate, the output end of the motor 305 is arranged at one end of the linkage shaft 304, and a plurality of paddles 306 movably installed inside the guide tube 301. The paddles 306 are evenly arranged on the outer surface of the linkage shaft 304. The lubricating oil in the lubricating oil box 3 will be blocked by the paddles 306. By turning on the motor 305, the linkage shaft 304 can be driven to rotate. When the linkage shaft 304 rotates, it can drive the paddles 306 to rotate inside the guide tube 301. Under the rotation of the paddles 306, the lubricating oil in the guide tube 301 can flow to the window opening chain 2.

[0056] Example 2:

[0057] On the basis of Example 1, in order to spread the lubricating oil more evenly on the surface of the window chain 2 , a coating structure for coating the lubricating oil on the window chain 2 is arranged on one side of the double-chain window opener 1 .

[0058] Among them, the smearing structure includes a rotating ring 4 and a limiting ring 401 arranged on one side of the double-chain window opener 1, the limiting ring 401 is rotatably installed inside the rotating ring 4, the sliding ring 402 is slidably installed on the inner wall of the rotating ring 4, the bristles 403 are arranged on the inner wall of the sliding ring 402, and a linkage component is arranged on the rotating ring 4 to drive the rotating ring 4 to rotate, the bristles 403 are in contact with the window chain 2, and the window chain 2 is located at the center of the rotating ring 4 and the sliding ring 402. When rotating, the rotating ring 4 can rotate on the limiting ring 401 on one side of the double-chain window opener 1, thereby avoiding the rotating ring 4 from being offset. The continuously rotating rotating ring 4 can drive the sliding ring 402 to rotate around the window chain 2, and then the sliding ring 402 drives the bristles 403 to brush the lubricating oil on the surface of the window chain 2.

[0059] Specifically, the linkage assembly includes a linkage gear ring 404 mounted on the outer surface of the rotating ring 4, and a linkage gear 405 mounted on the linkage shaft 304 for transmission. The linkage gear 405 is engaged with the linkage gear ring 404. The rotating linkage shaft 304 can drive the linkage gear 405 to rotate. The rotating linkage gear 405 can drive the rotating ring 4 to rotate by engaging with the linkage gear ring 404, thereby achieving the linkage effect.

[0060] Among them, the smearing structure also includes a swinging assembly arranged on the sliding ring 402 for driving the sliding ring 402 to swing back and forth, the swinging assembly includes a guide rod 406 slidably installed inside the sliding ring 402 to guide the movement of the sliding ring 402, a spring 407 movably sleeved on the guide rod 406, a plurality of arc-shaped extrusion blocks 408 arranged on one side of the sliding ring 402, and a plurality of arc-shaped extrusion blocks 409 arranged on one side of the annular frame 302. The arc-shaped extrusion block 409 is located on the active track of the arc-shaped extrusion block 408. The guide rod 406 is arranged on the inner wall of the rotating ring 4, and one end of the spring 407 is arranged on the inner wall of the rotating ring 4. It is placed on the inner wall of the rotating ring 4, and the other end of the spring 407 is arranged on one side of the sliding ring 402, which is used to drive the sliding ring 402 to move and reset. When the sliding ring 402 rotates, the arc-shaped extrusion block 1 408 will be continuously squeezed by the arc-shaped extrusion block 2 409, thereby driving the sliding ring 402 to move horizontally and compress the spring 407. When the arc-shaped extrusion block 1 408 is out of contact with the arc-shaped extrusion block 2 409, the spring 407 will push the sliding ring 402 to move and reset, and then it can move back and forth while the sliding ring 402 rotates, driving the bristles 403 to apply lubricating oil back and forth.

[0061] Working principle:

[0062] The lubricating oil is added into the lubricating oil box 3 so that the lubricating oil flows into the guide tube 301 and is blocked by the paddle 306. When the double-chain window opener 1 is used to recover the extended window chain 2, the motor 305 at the corresponding position can be turned on at the same time. The output end of the motor 305 can drive the linkage shaft 304 to rotate. When the linkage shaft 304 rotates, it can drive the paddle 306 to rotate inside the guide tube 301. Under the rotation of the paddle 306, the lubricating oil in the guide tube 301 can flow to the window chain 2 to lubricate the window chain 2. At the same time, the rotating linkage shaft 304 can drive the linkage gear 405 to rotate. The rotating linkage gear 405 can drive the rotating ring 4 to rotate by engaging with the linkage gear ring 404. When rotating, the rotating ring 4 can rotate on the limiting ring 401 on one side of the double-chain window opener 1, thereby preventing the rotating ring 4 from deflecting. The continuously rotating rotating ring 4 can drive the sliding The ring 402 rotates around the window chain 2, so that the sliding ring 402 drives the bristles 403 to brush the lubricating oil on the surface of the window chain 2, and while the sliding ring 402 rotates, it drives the arc-shaped extrusion block 1 408 to move in a circle. The arc-shaped extrusion block 1 408 will contact the arc-shaped extrusion block 2 409 during the movement. At the same time, the arc-shaped extrusion block 1 408 will be squeezed by the arc-shaped extrusion block 2 409 and drive the sliding ring 402 to move horizontally. The horizontally moving sliding ring 402 can slide on the guide rod 406 and compress the spring 407. When the arc-shaped extrusion block 1 408 is out of contact with the arc-shaped extrusion block 2 409, the compressed spring 407 will push the sliding ring 402 to move and reset, and then it can move back and forth while the sliding ring 402 rotates, driving the bristles 403 to brush back and forth, further improving the brushing effect of the lubricating oil on the surface of the window chain 2, so that the lubricating oil is evenly adhered to the window chain 2.

[0063] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
