Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, and more specifically, it relates to a locking structure for heat-insulating broken-bridge aluminum alloy doors and windows. Background Technique

[0002] The heat-insulating broken-bridge aluminum alloy doors and windows are improved types to enhance the heat-insulating effect of aluminum alloy doors and windows. They are insulated by arranging nylon heat-insulating strips inside to avoid heat conduction between aluminum strips.

[0003] Currently, during the long-term use of heat-insulating broken-bridge aluminum alloy windows, the glass frame is deformed by external factors, making the rotation and closing process of the glass frame more laborious. Moreover, after the glass frame is deformed, it will affect the airtightness between the glass frame and the heat-insulating broken-bridge aluminum alloy frame and may cause the fracture of the lock rod. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a locking structure for heat-insulating broken-bridge aluminum alloy doors and windows. By pushing the rotation of the glass frame tightly with a pressing plate, the rotation and closing process of the glass frame is made smoother, so that the closing process of the glass frame is more labor-saving. In addition, the use of the limiting component ensures the airtightness of the glass frame, avoids the deformation of the glass frame during long-term use, and prevents the fracture of the lock rod caused by excessive force on the lock rod, thereby further ensuring the safety of the lock rod during use.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A locking structure for heat-insulating broken-bridge aluminum alloy doors and windows includes an aluminum alloy window frame and a glass frame. The glass frame is hinged to the aluminum alloy window frame. A limiting component is arranged at the inner bottom of the aluminum alloy window frame. An L-shaped support rod is fixedly connected to an outer side surface of the glass frame. A first gear is fixedly connected to the top end of the L-shaped support rod. An installation plate is fixedly connected to an outer side surface of the aluminum alloy window frame. A rotating shaft is rotatably connected to the top of the installation plate. A second gear matched with the first gear is fixedly connected to the top end of the rotating shaft. A fixed rod is fixedly connected to the circumferential side surface of the rotating shaft. A pressing plate matched with the glass frame is fixedly connected to the end of the fixed rod.

[0007] A vertical plate is fixedly connected to an opposite outer side surface of the aluminum alloy window frame. A lock rod is slidably inserted into the vertical plate. A pulling plate is fixedly connected to one end of the lock rod. A second spring sleeved on the circumferential side surface of the lock rod is fixedly connected between the pulling plate and the vertical plate. A rectangular plate matched with the lock rod is fixedly connected to an opposite outer side surface of the glass frame.

[0008] The present utility model is further configured as follows: The limiting assembly includes a notch formed in the inner bottom of the aluminum alloy window frame. Guide rods are symmetrically and fixedly connected to the notch. A limiting plate is sleeved on the circumferential sides of the two guide rods. A path groove matching the glass frame is formed at the top of the limiting plate.

[0009] The present utility model is further configured as follows: A clockwork spring is arranged at the top of the mounting plate. A traction rope is fixedly connected between the clockwork spring and the rotating shaft.

[0010] The present utility model is further configured as follows: Through holes matching the lock rods are formed in the rectangular plate.

[0011] The present utility model is further configured as follows: Arc-shaped grooves matching the lock rods are formed on one side of the rectangular plate adjacent to the lock rods.

[0012] The present utility model is further configured as follows: Blind holes matching the two guide rods are symmetrically formed at the bottom of the limiting plate.

[0013] The advantages of the present utility model are as follows:

[0014] 1. By the rotation of the pressing plate to tightly push the glass frame, the rotation and closing process of the glass frame is smoother, making the closing process of the glass frame more labor-saving, and thus improving the convenience of use.

[0015] 2. By using the limiting assembly, when the glass frame is closed, the path groove catches the glass frame, thereby limiting the glass frame, ensuring the airtightness of the glass frame, reducing the force on the lock rods, and avoiding deformation of the glass frame during long-term use, which may cause the lock rods to break due to excessive force, thus further ensuring the safety of the lock rods during use.

[0028] Embodiment 1

[0029] Please refer to Figures 1-8 , the present utility model provides the following technical solutions:

[0030] Specifically, it refers to a heat-insulating broken-bridge aluminum alloy door and window locking structure, including an aluminum alloy window frame 1 and a glass frame 2. The glass frame 2 is hinged to the aluminum alloy window frame 1. A limiting component 24 is arranged at the inner bottom of the aluminum alloy window frame 1. An L-shaped support rod 8 is fixedly connected to an outer side surface of the glass frame 2. A first gear 9 is fixedly connected to the top end of the L-shaped support rod 8. An installation plate 10 is fixedly connected to an outer side surface of the aluminum alloy window frame 1. A rotating shaft 11 is rotatably connected to the top of the installation plate 10. A second gear 12 matched with the first gear 9 is fixedly connected to the top end of the rotating shaft 11. A fixing rod 13 is fixedly connected to the circumferential side surface of the rotating shaft 11. A pressing plate 14 matched with the glass frame 2 is fixedly connected to the end of the fixing rod 13. A hairspring 15 is arranged at the top of the installation plate 10. A traction rope 16 is fixedly connected between the hairspring 15 and the rotating shaft 11; A vertical plate 17 is fixedly connected to an opposite outer side surface of the aluminum alloy window frame 1. A locking rod 18 is slidably inserted into the vertical plate 17. A pulling plate 19 is fixedly connected to one end of the locking rod 18. A second spring 20 sleeved on the circumferential side surface of the locking rod 18 is fixedly connected between the pulling plate 19 and the vertical plate 17. A rectangular plate 21 matched with the locking rod 18 is fixedly connected to an opposite outer side surface of the glass frame 2. A through hole 22 matched with the locking rod 18 is formed in the rectangular plate 21. An arc-shaped groove 23 matched with the locking rod 18 is formed in a side surface of the rectangular plate 21 adjacent to the locking rod 18.

[0031] The specific application of this embodiment is as follows: During the process of the glass frame 2 rotating and closing, it drives the first gear 9 to rotate towards the aluminum alloy window frame 1. Among them, the first gear 9 drives the second gear 12, the rotating shaft 11 and the pressing plate 14 to rotate counterclockwise, so that the pressing plate 14 presses tightly against the glass frame 2. When the rectangular plate 21 on the glass frame 2 rotates and presses against the locking rod 18, it drives the locking rod 18 to move away from the rectangular plate 21. The locking rod 18 will move along the arc-shaped groove 23 on the rectangular plate 21. Under the elastic force of the second spring 20, it drives the locking rod 18 to move into the through hole 22 on the rectangular plate 21, thereby completing the automatic locking of the glass frame 2. During the process of the glass frame 2 rotating and closing, by pressing and pushing the rotation of the glass frame 2 through the pressing plate 14, it makes the process of the glass frame 2 rotating and closing smoother, so that the process of the glass frame 2 closing is more labor-saving, and thus the convenience of use is improved.

[0032] Embodiment Two

[0033] Please refer to Figures 1-8 , on the basis of Embodiment One, this Embodiment Two is improved as follows. Specifically, the limiting component 24 includes a notch 4 opened on the inner bottom of the aluminum alloy window frame 1. Guide rods 5 are symmetrically and fixedly connected to the notch 4. A limiting plate 3 is sleeved on the circumferential sides of the two guide rods 5 together. Blind holes matched with the two guide rods 5 are symmetrically opened at the bottom of the limiting plate 3. A path groove 7 matched with the glass frame 2 is opened at the top of the limiting plate 3.

[0034] A specific application of this embodiment is as follows: During the process of the glass frame 2 rotating to close with the aluminum alloy window frame 1, the glass frame 2 squeezes and contacts the limit plate 3, driving the limit plate 3 to move downward. The glass frame 2 moves along the path groove 3 on the limit plate 3. When the glass frame 2 is closed with the aluminum alloy window frame 1, under the elastic force of the first spring 6, the limit plate 3 is driven to move upward, so that the path groove 7 catches the glass frame 2, thereby limiting the glass frame 2, ensuring the airtightness of the glass frame, reducing the force on the lock rod 18, and avoiding deformation of the glass frame 2 during long-term use, which may cause the lock rod 18 to break due to excessive force, further ensuring the safety of the lock rod 18 during use.
