Description

Technical Field

[0001] The utility model relates to an adjustable hinge structure. Background Technique

[0002] Door and window hinges are used for openable doors and windows. In addition to the functions of opening and closing, they also affect the performance and appearance of doors and windows. Under the national demand for energy conservation, environmental protection and green buildings, the performance of doors and windows is also crucial.

[0003] At present, hinges in the industry require drilling holes or built-in backplates during installation. The production and installation processes are complex, the installation is inconvenient, the production efficiency is affected, the adjustable functions in application are complex, and there are many operation steps, which are time-consuming and laborious. The adjustment effect is not ideal, such as misalignment of the hinge shaft during left-right adjustment and gaps during height adjustment, which seriously affect the appearance and service life of doors and windows.

[0004] For the left-right adjustment of common hinges in the market, some need to loosen the fixing screws to change the relative position of the frame and sash, and then tighten the screws. There are also conventional market methods of loosening the fixing screws to increase the thickness of the gasket to achieve the left-right position change of the frame and sash. Repeated adjustment will be more cumbersome and inefficient, and the operation is not convenient. Some also use cam-type hinge bushings, which require removing the sash and rotating the direction of the bushing to adjust the position of the frame and sash. There are problems such as small adjustment amount, only 2 fixed data for adjustment, and non-continuous stepless adjustment. In addition, there will be a misalignment phenomenon of the frame and sash profiles after installation, which affects the appearance. Content of the Utility Model

[0018] The following only uses embodiments to illustrate the possible implementation modes of the present utility model, but is not intended to limit the scope of protection of the present utility model. It is stated first.

[0019] As Figures 1 to 8 shown, it is an adjustable hinge structure of the present utility model, including a hinge frame part 1, a hinge fan part 2 and a hinge shaft 3. Both ends of the hinge fan part 2 are respectively provided with the hinge frame part 1 and are hinged to the hinge shaft 3. The hinge frame part is fixedly connected to the hinge shaft. A fan profile 21 and a fan housing 22 are provided on the side of the hinge fan part 2. A threaded through hole 2111 is provided in the guiding part 211 of the fan profile 21. An adjusting screw 2112 is screwed in the threaded through hole 2111. Guiding holes 2113 are provided on both sides of the threaded through hole 2111. Both ends of the fan housing 22 are connection heads 221. Between the two connection heads is a U-shaped groove plate 222. Two mounting holes 2221 opposite to the guiding holes 2113 are provided on one side plate of the U-shaped groove plate 222. A screw perforation 2222 opposite to the mounting hole is provided on the other side plate of the U-shaped groove plate. An adjusting hole 2223 opposite to the head of the adjusting screw 2112 is provided between the two screw perforations 2222. A slider 23 is installed on the aligned mounting holes and guiding holes. The slider is fixed to the fan housing by a fixing screw. The fan housing and the connected slider can move left and right along the guiding holes under the action of the adjusting screw.

[0020] First, screw the adjusting screw 2112 into the threaded through hole 2111, then insert the guide part 211 into the U-shaped groove of the U-shaped groove plate 222, align the mounting hole 2221 with the guide hole 2113, and align the head of the adjusting screw 2112 with the adjusting hole 2223, then insert the two sliders 23 into the mounting hole 2221 and the guide hole 2113 respectively, insert the lower end of the fixing screw 231 into the through hole of the slider through the mounting hole in turn and penetrate and fix it through the screw hole, and the fan profile is connected to the fan housing. The hinge frame part 1 is fixed to the frame 10 through the frame connecting back plate 11, and the connecting head 221 and the fan back plate 223 of the fan housing 22 are connected to the fan 20 by tightening the screws. When the adjusting screw 2112 is rotated forward and backward, when one end of the adjusting screw contacts the corresponding side plate of the U-shaped groove plate, continuing to screw the adjusting screw will push the fan housing and the connected slider to move along the guide hole to achieve left and right adjustment of the fan, and finally adjust the appropriate gap between the fan and the frame.

[0021] Specifically, Figure 1 As shown, the hinge fan part 2 includes a fan profile 21, a fan housing 22 and a hinge shaft tube 23A, the fan profile 21 includes a Z-shaped connecting plate 210 and the guide portion 211, the front side plate free end of the Z-shaped connecting plate 210 is arranged on the hinge shaft tube facing the fan side, the rear side of the free end of the rear side plate of the Z-shaped connecting plate is provided with a guide portion 211, the guide portion 211 includes a plug plate 2110 and an adjusting screw 2112, one end of the plug plate 2110 is L-shaped and is arranged on the rear side of the free end of the rear side plate of the Z-shaped connecting plate, and the plug plate Guide holes 2113 are provided at both ends of 2110, and a threaded through hole 2111 matching the adjusting screw is provided between the two guide holes 2113. The width of the U-shaped groove of the U-shaped groove plate 222 is greater than the thickness of the guide portion, so that under the action of the adjusting screw 2112, the fan housing 22 and the slider 23 can move along the guide hole 2113, that is, by screwing the adjusting screw, the two ends of the fan housing 22 and the slider 23 can intermittently abut against the two side plates of the corresponding U-shaped groove plate, so as to realize the movement of the fan housing and the slider along the guide hole, thereby realizing the adjustment of the left and right gaps between the fan and the frame.

[0022] The fan back plate 223 includes a T-shaped base plate, which cooperates with the T-slot of the fan. An L-shaped groove 2231 is provided on one side of the small end wall of the T-shaped base plate, and a nail hole is provided in the middle. The connecting head 221 includes a U-shaped base plate. The two side plates of the U-shaped base plate are pressed against the two end plates of the notch of the T-slot of the fan. An L-shaped plug plate 2210 cooperating with the L-slot is convexly provided at the bottom of the groove of the U-shaped base plate. The bottom plate of the U-shaped base plate is provided with screw holes aligned with the nail holes. During the installation process, the fan back plate is inserted into the fan T-slot in advance, and the fan hinge finds the installation position on the upper and lower sides of the hinge, respectively. The bottom surface of the fan shell is close to the fan T-slot, and the fan back plate slides to the position of the fan shell. The fan back plate is connected with the fan shell by snapping, and the nail holes of the fan back plate are aligned with the screw holes of the fan shell. The screws are tightened to realize the installation of the fan hinge.

[0023] The fan back plate above the fan housing will fall on the back position of the fan housing. Additionally, the L-shaped groove and L-shaped insertion plate structure can integrate the two parts into one. When adjusting the height, the clamping structure can prevent damage to the screws and connecting threads when loosening the screws, ensuring product stability, extending product life, avoiding the risk of the fan falling off, improving safety and reliability. During installation, positioning is convenient and installation is fast.

[0024] The hinge of the present utility model is quickly installed for both the connection with the frame of the door and window and the connection with the fan, without the need for processing, ensuring the integrity of the door and window. The left and right adjustment is achieved by directly screwing the set screws, and the adjustment is safe and simple, effectively improving the processing and installation efficiency.
