Description

Technical Field

[0001] The utility model relates to the technical field of door and window fittings, in particular to a hinge for a thin wood-aluminum plastic composite door and window. Background Art

[0002] At present, in the construction industry, medium and high-grade doors and windows generally adopt aluminum-wood composite doors and windows and pure wood doors and windows. They are beautiful, have good sealing performance, and are easy to install, so they are favored by most builders. However, with the shortage of energy, their prices remain high, which has greatly increased the production cost of doors and windows. At the same time, for plastic-steel doors and windows on the market, during the use process, since the outer side of the doors and windows is often irradiated by sunlight, they are prone to aging and deformation, which destroys the overall aesthetics and shortens the service life. At the same time, they can neither meet the various building decoration needs as rich and colorful as aluminum alloy windows, nor have the natural tree texture of wooden windows, which is beautiful and elegant.

[0003] In the prior art, most hinge-type thin wood-aluminum plastic composite doors and windows adopt hinges for connection, and generally, multiple screws are required to install the hinges between the door and window frames and the door and window panels, resulting in time-consuming and laborious installation and being difficult to meet the modern convenient use requirements.

[0004] Therefore, how to design a hinge for a thin wood-aluminum plastic composite door and window has become a problem that needs to be solved currently. Content of the Utility Model

[0005] The utility model aims at the deficiencies of the prior art and provides the following technical solution: A hinge for a thin wood-aluminum plastic composite door and window, including a door and window frame, a door and window panel, a fixing block, a connecting block and a rotating shaft. Fixing blocks are fixedly connected to the surfaces of the door and window frame and the door and window panel respectively. The two connecting blocks are hinged through the rotating shaft. Locking grooves are formed at both ends of the connecting block, grooves are formed at both ends of the fixing block, springs are fixedly connected inside the grooves, and a locking block is fixedly connected to one end of each spring;

[0006] A cavity is formed in the middle of the fixing block. One end of the spring close to the spring is fixedly connected to a connecting rod. One end of the connecting rod slides and extends into the cavity and is fixedly connected to a pushing block. A bidirectional screw is rotatably connected inside the cavity. A driving component is arranged in the middle of the bidirectional screw, and pushing plates are threadedly connected to both ends of the bidirectional screw.

[0007] As an improvement of the above technical solution, the end of the locking block away from the spring is provided with an inclined angle.

[0008] As an improvement of the above technical solution, limiting grooves are formed on the inner wall of the groove, a limiting block is fixedly connected to one side of the locking block, and the limiting block slides in the limiting groove.

[0009] As an improvement to the above technical solution, the driving assembly includes a nut, a worm and a worm gear. The nut is fixedly connected to one end of the worm, and the worm gear is fixedly installed in the middle of the bidirectional screw and meshes with the worm.

[0010] As an improvement to the above technical solution, a receiving groove is formed on the surface of the fixed block, and the nut is embedded in the receiving groove.

[0011] As an improvement to the above technical solution, a guide rod is fixedly installed on one side of the bidirectional screw inside the cavity, and the pushing plate is slidably sleeved on the guide rod.

[0012] As an improvement to the above technical solution, a through hole is formed in the center of the pushing plate, the connecting rod movably passes through the through hole, and the inner diameter of the through hole is smaller than the outer diameter of the pushing block.

[0013] Advantages of the present utility model:

[0014] Through the settings of the fixed block, the connecting block and the rotating shaft, when installing the hinge to connect the door and window frame and the door and window panel, just hold the connecting block and put it on the fixed block. When the connecting block fits with the fixed block, the spring will push the locking block into the locking groove to lock the connecting block, so that the fixed block and the connecting block are tightly combined, thus realizing the installation of the hinge without using screws, which is time-saving and labor-saving to meet the modern convenient use requirements.

[0015] Through the cooperation of the connecting rod, the pushing block, the bidirectional screw, the driving assembly and the pushing plate, when it is necessary to disassemble the hinge, just rotate the bidirectional screw through the driving assembly, so that the bidirectional screw drives the two pushing plates to approach each other, the pushing plate pushes the pushing block to move, and the pushing block pulls out the locking block from the locking groove through the connecting rod, then the hinge can be disassembled and the door and window panel can be separated from the door and window frame, and the operation is convenient.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] As Figures 1-3 shown, the present utility model provides a technical solution: a hinge for a veneer aluminum-plastic composite door and window, including a door and window frame 1, a door and window panel 2, a fixing block 3, a connecting block 4 and a rotating shaft 5. Fixing blocks 3 are fixedly connected to the surfaces of the door and window frame 1 and the door and window panel 2. The fixing blocks 3 are pre-installed on the door and window frame 1 and the door and window panel 2. The two connecting blocks 4 are hinged through the rotating shaft 5. Locking grooves 41 are opened at both ends of the connecting block 4. Grooves 31 are opened at both ends of the fixing block 3. A spring 32 is fixedly connected inside the groove 31. One end of the spring 32 is fixedly connected to a locking block 33. The end of the locking block 33 away from the spring 32 is provided with an inclined angle. Through the settings of the fixing block 3, the connecting block 4 and the rotating shaft 5, when installing the hinge to connect the door and window frame 1 and the door and window panel 2, only need to hold the connecting block 4 and sleeve it on the fixing block 3. When the connecting block 4 fits with the fixing block 3, the spring 32 will push the locking block 33 into the locking groove 41 to lock the connecting block 4, so that the fixing block 3 and the connecting block 4 are closely combined, thereby realizing the installation of the hinge, without using screws, saving time and effort, so as to meet the modern convenient use requirements.

[0022] Wherein, a limiting groove 39 is opened on the inner wall of the groove 31. A limiting block 310 is fixedly connected to one side of the locking block 33. The limiting block 310 slides in the limiting groove 39. Through the cooperation of the limiting groove 39 and the limiting block 310, the locking block 33 can be limited.

[0023] Referring to Figure 2 and Figure 3, a cavity is formed in the middle of the fixed block 3. One end of the spring 32 close to the spring 32 is fixedly connected with a connecting rod 34. One end of the connecting rod 34 slides and extends into the cavity and is fixedly connected with a pushing block 35. A bidirectional screw 36 is rotatably connected in the cavity. A driving assembly 37 is arranged in the middle of the bidirectional screw 36. Both ends of the bidirectional screw 36 are threadedly connected with a pushing plate 38. A through hole 313 is formed in the center of the pushing plate 38. The connecting rod 34 movably penetrates through the through hole 313, and the inner diameter of the through hole 313 is smaller than the outer diameter of the pushing block 35. A guide rod 312 is fixedly installed on one side of the bidirectional screw 36 inside the cavity. The pushing plate 38 is slidably sleeved on the guide rod 312. Through the cooperation of the connecting rod 34, the pushing block 35, the bidirectional screw 36, the driving assembly 37 and the pushing plate 38, when it is necessary to disassemble the hinge, only need to rotate the bidirectional screw 36 through the driving assembly 37, so that the bidirectional screw 36 drives the two pushing plates 38 to approach each other, so that the pushing plate 38 pushes the pushing block 35 to move, so that the pushing block 35 pulls out the locking block 33 from the locking groove 41 through the connecting rod 34, and the hinge can be disassembled, and the door and window panel 2 can be separated from the door and window frame 1, and the operation is convenient.

[0024] Specifically, the driving assembly 37 includes a nut 371, a worm 372 and a worm gear 373. A receiving groove 311 is formed on the surface of the fixed block 3. The nut 371 is embedded in the receiving groove 311, and the nut 371 is fixedly connected to one end of the worm 372. The worm 372 rotates and extends into the cavity. The worm gear 373 is fixedly installed in the middle of the bidirectional screw 36 and meshes with the worm 372. Through the setting of the driving assembly 37, only need to use a tool to twist the nut 371, so that the nut 371 drives the worm 372 to rotate, and the worm 372 drives the worm gear 373 to rotate, then the bidirectional screw 36 can be driven to rotate.

[0025] The implementation principle of the present utility model is: through the settings of the fixed block 3, the connecting block 4 and the rotating shaft 5, when installing the hinge to connect the door and window frame 1 and the door and window panel 2, only need to hold the connecting block 4 and sleeve it on the fixed block 3. When the connecting block 4 fits with the fixed block 3, the spring 32 will push the locking block 33 into the locking groove 41 to lock the connecting block 4, so that the fixed block 3 and the connecting block 4 are tightly combined, thereby realizing the installation of the hinge, without using screws, saving time and effort, so as to meet the modern convenient use requirements.

[0026] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it.
