Description

Technical Field

[0001] This utility model relates to the field of door and window mechanical structure technology, and in particular to a multi-locking point structure for aluminum alloy doors and windows. Background Technology

[0002] With the increasing awareness of residential security and the development of building technology, multi-point locking structures have emerged to enhance the pry resistance and anti-theft capabilities of doors and windows. Multi-point locking technology involves installing multiple locking points (such as spring hooks and bolts) on the door frame, which tightly seal the door leaf from all directions when locked, increasing the difficulty of damage and effectively preventing intrusion or forced opening by strong winds. Aluminum alloy doors and windows, due to their advantages such as being lightweight, corrosion-resistant, and easy to process, have gradually become the preferred material for residential and commercial buildings. Applying multi-point locking structures to aluminum alloy doors and windows combines sturdiness with aesthetics, effectively improving the security performance of doors and windows.

[0003] However, the existing multi-point locking structure of aluminum alloy doors and windows has the following disadvantages:

[0004] (1) At present, the door and window fixing effect of this device is not good. It is easy to shake when facing some windy weather. At the same time, its own safety effect is not good.

[0005] (2) Currently, the handle is used frequently during long-term use of the device, which will cause some damage to the handle. The handle needs to be disassembled and replaced regularly. However, traditional handles are not easy to disassemble, requiring staff to spend a lot of time. Utility Model Content

[0006] (a) Technical problems to be solved

[0016] (III) Beneficial Effects

[0017] This utility model provides a multi-locking point structure for aluminum alloy doors and windows, which has the following advantages:

[0018] 1. This aluminum alloy door and window features a multi-point locking structure. Through the arrangement of A-plate, B-plate, limiting block, sliding block, and connecting block, the movement of A-plate and B-plate wraps around the position of the rotating block. At the same time, the sliding block ensures the direction of movement of A-plate and B-plate.

[0019] 2. This aluminum alloy door and window features a multi-locking structure. Through the arrangement of rotating gears, gear plates, snap-fit ​​blocks, fixing blocks, and telescopic springs, the rotation of the rotating gears drives the gear plates and snap-fit ​​blocks to move up and down. This allows the snap-fit ​​blocks to smoothly enter the inner wall of the mounting frame and effectively fix the door and window body to the inner wall of the mounting frame. The multi-locking structure ensures the stability of the door and window body and prevents it from becoming loose later. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 6 This utility model provides a technical solution: a multi-locking structure for aluminum alloy doors and windows, including a disassembly assembly 1. The disassembly assembly 1 includes an A-plate 11, a B-plate 12, a limiting block 13, a sliding block 14, a connecting block 15, and a bolt 16. Through the arrangement of the A-plate 11 and the B-plate 12, the position of the rotating block 5 can be fixed. One side of the A-plate 11 is in contact with the side of the B-plate 12. The side of the limiting block 13 is fixedly connected to one side of the B-plate 12, and the outer surface of the limiting block 13 is located inside the A-plate 11. One side of the connecting block 15 is fixedly connected to the outer surface of the B-plate 12, and the outer surface of the bolt 16 is threadedly connected to the connecting block 15 and the interior of the A-plate 11. The front of the sliding block 14 is fixedly connected to the back of the A-plate 11.

[0029] The back of the A-plate 11 and the B-plate 12 are fitted with the door and window body 2. A sliding groove is provided on one side of the door and window body 2, and the outer surface of the sliding block 14 is slidably connected to the inner wall of the sliding groove.

[0030] The door and window body 2 is equipped with an installation frame 3 on its exterior, and one end of the door and window body 2 is rotatably connected to the inner wall of the installation frame 3. The door and window body 2 has a slot inside, and a multi-lock component 4 is installed inside the slot. The position of the door and window body 2 can be restricted by the installation frame 3.

[0031] The multi-lock assembly 4 includes a rotating gear 41, a gear plate 42, a locking block 43, a fixing block 44, a telescopic spring 45, and a stabilizing column 46. The rotating gear 41 and the gear plate 42 mesh with each other, and one side of the gear plate 42 is fixedly connected to the side of the locking block 43. With the setting of the rotating gear 41, when the rotating gear 41 rotates, it can drive the gear plate 42 and the locking block 43 to move up and down.

[0032] The outer surface of the snap-fit ​​block 43 snaps into the interior of the mounting frame 3, the outer surface of the fixing block 44 is fixedly connected to the inner wall of the door and window body 2, one side of the fixing block 44 is fixedly connected to one end of the stabilizing column 46, and the other end of the stabilizing column 46 is located inside the gear plate 42. Through the setting of the snap-fit ​​block 43, the door and window body 2 can be firmly fixed inside the mounting frame 3.

[0033] The two ends of the telescopic spring 45 are fixedly connected to the connection between the fixed block 44 and the gear plate 42. The rotating gear 41, the gear plate 42 and the telescopic spring 45 are all located inside the door and window body 2. Through the setting of the gear plate 42, it can drive the locking block 43 to move synchronously by its own movement.

[0034] A rotating block 5 is fixedly installed on one side of the rotating gear 41, and a handle 6 is fixedly installed on one end of the rotating block 5. One side of the rotating block 5 is in contact with the sides of the A clamp plate 11 and the B clamp plate 12. The handle 6 makes it convenient for staff to open and close the door and window body 2.

[0035] In this invention, the working steps of the device are as follows:

[0036] First step: First, rotate the door and window body 2 so that the door and window body 2 can smoothly enter the interior of the mounting frame 3. Then, rotate the handle 6. The rotation of the handle 6 will drive the rotating block 5 and the rotating gear 41 to rotate synchronously. Under the cooperation of the rotating gear 41, the gear plate 42 will drive the snap-fit ​​block 43 to move towards the mounting frame 3 and enter the interior of the mounting frame 3, thereby firmly fixing the door and window body 2 inside the mounting frame 3.

[0037] Second step: Finally, when it is necessary to replace the handle 6 and the rotating block 5, loosen the bolt 16 to release the positional relationship between the A clamp plate 11 and the B clamp plate 12. With the help of the sliding block 14, move the A clamp plate 11 and the B clamp plate 12 away from the rotating block 5, so that the rotating block 5 is freed from the restriction of the A clamp plate 11 and the B clamp plate 12, thereby making it convenient for the staff to quickly disassemble the handle 6. At this point, the overall operation process is completed.
