Description

Technical Field

[0001] This utility model relates to the field of anti-theft ventilation doors, specifically an anti-theft ventilation door. Background Technology

[0002] A security and ventilation door, as the name suggests, is a door that combines security and ventilation. It uses the same robust materials and locks as traditional security doors, effectively preventing theft and ensuring home safety. At the same time, its unique feature is the ventilation window designed into the door body; opening the inner mesh door allows for free air circulation between the inside and outside, keeping the room cool and fresh.

[0003] One existing type of burglarproof ventilation door, specifically referring to the burglarproof door with good ventilation as described in application number CN202422595313.8, includes a door frame, with a rotatable burglarproof door body connected to the door frame. The burglarproof door body has an internal cavity, and a movable device is installed inside the cavity. This invention utilizes the movable device to separate the locking block from the movable plate by twisting a locking block on the movable plate, taking advantage of the rotational characteristics of the damping shaft. Subsequently, the user pulls a second handle, causing the movable plate to rotate via a rotating rod, thus achieving ventilation. Users can precisely control the degree of ventilation by flexibly adjusting the number of movable plates opened, following the same operating steps. This avoids the problem of accurately controlling the ventilation volume in traditional ventilation windows due to the use of a single movable door control. It not only improves the ease of use of the burglarproof door but also gives users greater autonomy to adjust the ventilation volume according to actual needs, thereby achieving the dual functions of ventilation and burglarproofing.

[0004] The aforementioned device does not have any components that can be easily removed. When it is necessary to remove the ventilation panel for later cleaning, the existing device cannot easily remove the ventilation panel, which increases the difficulty of cleaning later. Therefore, a burglarproof ventilation door is proposed to address the above problems. Utility Model Content

[0027] The dismantling mechanism includes a housing 10, which is also located on the left and right sides of the rear end of the door body 1. The front end of the housing 10 is fixedly connected to the rear end of the door body 1. The ventilation plate 2 is inserted inside the housing 10 and is slidably connected to the housing 10. The housing 10 and the ventilation plate 2 are also inserted with one end of a positioning rod 11 inside the left and right sides. The housing 10 and the ventilation plate 2 are also slidably connected with the positioning rod 11. The other end of the positioning rod 11 is fixedly connected to the moving plate 12. The positioning rod 11 is a round rod design.

[0028] During operation, the movable plate 12 and the positioning rod 11 move. When the positioning rod 11 moves, it will move outward along the inside of the ventilation plate 2 and the sleeve 10 until it is completely separated from the inside of the ventilation plate 2. Then, the ventilation plate 2 is pulled down, which will drive the ventilation plate 2 to move outward along the inside of the sleeve 10 until it is separated.

[0029] Furthermore, the side end of the movable plate 12 near the upper position is fixedly connected to one end of the transmission block 13. The movable plate 12 and the transmission block 13 are also sleeved on the outside of the first guide rod 18, and the movable plate 12 and the transmission block 13 are also slidably connected to the first guide rod 18. Fixing blocks 19 are also provided on the left and right sides of the first guide rod 18, and the side ends of the first guide rod 18 and the fixing blocks 19 are fixedly connected. The front end of the fixing blocks 19 is fixedly connected to the rear end of the door body 1. The first guide rod 18 is a circular rod design.

[0030] During operation, the transmission block 13 and the moving plate 12 move simultaneously along the outer side of the first guide rod 18, and the fixing block 19 is used to fix and support the position of the first guide rod 18.

[0031] Furthermore, a return spring 20 is sleeved on the outer side of the first guide rod 18. One end of the return spring 20 is fixedly connected to the transmission block 13, and the other end of the return spring 20 is fixedly connected to the fixing block 19.

[0032] When in operation, the transmission block 13 moves, which will pull the return spring 20 on the outside of the first guide rod 18 to extend.

[0039] Working principle: First, press the pressing plate 17 against the door body 1. When the pressing plate 17 presses against the door body 1, it will simultaneously drive the second fixed seats 16 on both sides to move. When the second fixed seats 16 move, they will squeeze the rotating push rod 15 to move synchronously. The rotating push rod 15 rotates along the outer side of the second fixed seat 16. When the rotating push rod 15 rotates, it will also rotate along the outer side of the first fixed seat 14, applying an outward pushing force to the first fixed seat 14. When the first fixed seat 14 is pushed, it will simultaneously drive the transmission block 13 to move outward. When the transmission block 13 moves outward, it will simultaneously drive the moving plate 12 and the positioning plate 13 to move outward. When the insertion rod 11 moves, it will move outward along the inside of the ventilation plate 2 and the sleeve 10 until it is completely separated from the inside of the ventilation plate 2. Then, the ventilation plate 2 is pulled down, which will drive the ventilation plate 2 to move outward along the inside of the sleeve 10 until it is separated. At the same time, when the transmission block 13 and the moving plate 12 move, they will move along the outside of the first guide rod 18. The fixing block 19 is used to fix and support the position of the first guide rod 18. At the same time, when the transmission block 13 moves, it will pull the return spring 20 on the outside of the first guide rod 18 to extend.
