Abstract
Description
Technical Field
[0001] This invention relates to the field of aluminum alloy door technology, and more specifically to an aluminum alloy door. Background Technology
[0002] Application number 202021567137.2 describes a protective aluminum alloy door. It includes an aluminum alloy door and a protective unit. The side wall of the aluminum alloy door has a baffle made of aluminum alloy plate. A door lock is located on the inner side wall of the baffle. Eight springs are used, with two sets of springs positioned at the upper and lower ends of the inner side wall of the baffle. A buffer plate is located between the four springs in each set. Suction cups (rubber suction cups) are located at both the upper and lower ends of the inner side wall of the buffer plate. Four air pipes are positioned on the outer side wall of the buffer plate, corresponding to the four suction cups. One end of each air pipe connects to a suction cup, and the other end is equipped with a solenoid valve. This design buffers the impact between the aluminum alloy door and the door frame, protecting the door and preventing it from bouncing back upon impact, thus extending its service life. However, this aluminum alloy door cannot protect the through-slot in the translucent glass area. Summary of the Invention
[0003] To overcome the shortcomings of existing technologies, this invention provides an aluminum alloy door, which has the beneficial effect of protecting the ventilation openings from theft and improving the safety performance of the aluminum alloy door.
[0004] The technical solution adopted by this invention to solve its technical problem is:
[0005] An aluminum alloy door includes a door frame, a door body hinged inside the door frame, a ventilation opening through the middle of the door body, a protective filter screen detachably connected inside the ventilation opening, a vertical core groove through the middle of the door body communicating with the ventilation opening, and an upper baffle and a lower baffle symmetrically slidably connected inside the core groove to block the ventilation opening.
[0006] The lower end of the upper baffle is fixed with a plurality of protective plates that can be inserted into the lower baffle.
[0007] The lower baffle is fixed with multiple protective rods that can be inserted into the upper baffle.
[0008] The protective plates and protective rods are arranged alternately at intervals.
[0009] Two slots are symmetrically opened at the bottom of the door body, and a bottom groove is opened at the bottom of the door frame. Both ends of the bottom groove are hinged with hinge rods that can be inserted into the slots. Attached Figure Description

Detailed Implementation
[0026] like Figures 1 to 7 As shown:
[0027] An aluminum alloy door includes a door frame 101, a door body 201 hinged inside the door frame 101, a ventilation opening 202 extending through the middle of the door body 201, a protective filter 204 detachably connected inside the ventilation opening 202, a vertical core groove extending through the middle of the door body 201 and communicating with the ventilation opening 202, and an upper baffle 301 and a lower baffle 401 symmetrically slidably connected inside the core groove to block the ventilation opening 202;
[0028] When the door 201 is closed within the door frame 101, the upper baffle 301 and the lower baffle 401 are in contact with each other, blocking the ventilation opening 202. When ventilation is needed, the upper baffle 301 and the lower baffle 401 are separated, exposing the ventilation opening 202. The exposed ventilation opening 202 can form a small window for ventilation when the door 201 is closed. When the upper baffle 301 and the lower baffle 401 are close to each other, they block the ventilation opening 202. The protective filter 204 in the ventilation state can also serve as an anti-theft device. Therefore, it is convenient to open the small window for indoor ventilation when needed, while ensuring indoor security and improving the safety performance of the aluminum alloy door. The ventilation opening 202 is detachably connected to the protective filter 204 by screws, making it easy to replace the protective filter 204 when it is damaged.
[0029] Furthermore, transparent glass can be installed at the location of the ventilation opening 202 to replace the protective filter 204, thereby improving the light transmittance of the door 201. When the upper baffle 301 and the lower baffle 401 are closed, the transparent glass will be blocked to provide light protection.
[0030] like Figure 4 and 7 As shown:
[0031] The lower end of the upper baffle 301 is fixedly connected with a plurality of protective plates 303 that can be inserted into the lower baffle 401;
[0032] When the upper baffle 301 and the lower baffle 401 are in the separated open state, multiple protective plates 303 can block the ventilation opening 202, further improving the protective effect. This ensures that even if the protective filter 204 or transparent glass is damaged, the multiple protective plates 303 can still block the ventilation opening 202 and play a protective role, thus improving the protective performance of the aluminum alloy door. When the upper baffle 301 and the lower baffle 401 are close together, the protective plates 303 can be inserted into the lower baffle 401 for storage.
[0033] like Figure 5 and 7 As shown:
[0034] Multiple protective rods 403 that can be inserted into the upper baffle 301 are fixedly connected to the lower baffle 401;
[0035] When the upper baffle 301 and the lower baffle 401 are in the separated open state, multiple protective rods 403 can block the vent 202, further improving the protective effect. This ensures that even if the protective filter 204 or transparent glass is damaged, the multiple protective rods 403 can still block the vent 202 and play a protective role, thus improving the protective performance of the aluminum alloy door. When the upper baffle 301 and the lower baffle 401 are close together, the protective rods 403 can be inserted into the upper baffle 301 for storage.
[0036] like Figure 8 As shown:
[0037] The protective plates 303 and protective rods 403 are arranged alternately to avoid interference between the upper baffle 301 and the lower baffle 401 when they are close together.
[0038] Secondly, the protective plate 303 and the protective rod 403 work together to form a protective barrier. At the same time, the staggered arrangement of the protective plate 303 and the protective rod 403 increases the density of the protective barrier, making the protective performance stronger. It also prevents thieves from reaching in to unlock the door when the protective filter 204 or transparent glass is damaged, because the distance between adjacent protective rods 403 and protective plates 303 is relatively large. This forms a secondary protection.
[0039] like Figure 3 and 6 As shown:
[0040] Two sliding grooves 203 connected to the core groove are symmetrically opened on the door body 201. Slide I 302 and slide II 402 are fixedly connected to the upper baffle 301 and the lower baffle 401, respectively. Slide I 302 and slide II 402 are slidably connected in the two sliding grooves 203. A dual-axis motor is fixedly connected to the door body 201. The output shafts on both sides of the dual-axis motor are respectively connected to screws 205 through couplings. Slide I 302 and slide II 402 are threadedly connected to the two screws 205 respectively.
[0041] The dual-axis motor starts and drives two screws 205 with opposite screw directions to rotate. The two screws 205 drive slide I 302 and slide II 402 to slide closer to each other or further away from each other, thereby causing the upper baffle 301 and lower baffle 401 to move closer to each other to close the vent 202, or move away from each other to open the vent 202.
[0042] like Figure 2 , 9 As shown in 10 and 14:
[0043] The bottom of the door body 201 has two symmetrical slots 206, and the bottom of the door frame 101 has a bottom groove 102. Both ends of the bottom groove 102 are hinged with hinge rods 106 that can be inserted into the slots 206.
[0044] When the two hinge rods 106 are in a horizontal position under normal conditions, the door 201 can be opened and closed at will. When the door 201 is closed inside the door frame 101, both slots 206 are connected to the bottom groove 102. When the two hinge rods 106 are rotated upward and inserted into the two slots 206 respectively, the door 201 can be further prevented from being opened without cause, thus providing a further anti-theft function.
[0045] like Figure 11 and 13 As shown in Figure 14:
[0046] A pressure plate 104 is slidably connected in the bottom groove 102. Two compression springs 103 are fixed between the pressure plate 104 and the bottom surface of the bottom groove 102. A lever 105 is fixedly connected to both ends of the pressure plate 104. A sliding groove 108 is opened on the inner side of the two hinge rods 106. The two levers 105 are slidably connected in the two sliding grooves 108 respectively.
[0047] Under normal conditions, the pressure plate 104 is supported upward by the elastic force of the two compression springs 103. The pressure plate 104, through the cooperation of the two levers 105 and the two slides 108, keeps the two hinge rods 106 in a horizontal state. When the pressure plate 104 is subjected to downward pressure and moves downward, the two compression springs 103 are compressed, and the two levers 105 slide downward in the two slides 108, causing the two hinge rods 106 to rotate upward and insert into the two slots 206, thereby preventing the door 201 in the closed state from being opened when the door lock fails.
[0048] like Figures 8 to 9 And as shown in 12 to 14:
[0049] The lower baffle 401 is connected to a bracket 404, which can press the pressure plate 104 to drive the two hinge rods 106 to rotate upward and enter the two slots 206.
[0050] When the upper baffle 301 and the lower baffle 401 slide away from each other to the open state, the lower baffle 401 drives the insert 404 to move downward. After the insert 404 passes through the fixed plate 107 and contacts the pressure plate 104, it presses the pressure plate 104 downward, causing the pressure plate 104 to drive the two hinge rods 106 to rotate upward through the two levers 105 and enter the two slots 206. Thus, when the vent 202 is open and in the ventilation state, the two hinge rods 106 are automatically driven to insert into the slots 206, so that the door enters the third-level protection state. In this way, even if the first-level protection filter 204, the second-level protection plate 303 and the protection rod 403 are damaged, the two slots 206 of the third-level protection can still prevent the door 201 from being opened.
[0051] like Figure 8 As shown:
[0052] A stud 405 is threaded onto the slide II 402, and the stud 405 is rotatably connected to the insert 404;
[0053] When the door 201, which is in a ventilated state, needs to be opened, the stud 405 is manually turned from inside to move the bracket 404 upward and separate it from the pressure plate 104 and the fixing plate 107. The two compression springs 103 reset the pressure plate 104, and at the same time, the two hinge rods 106 also separate from the two slots 206. At this time, the door 201 can be opened, so that the three-level protection formed by the two slots 206 can be released at any time when it is in a ventilated state.
[0054] like Figures 10 to 11 As shown:
[0055] The bottom groove 102 is detachably connected to the upper end of the pressure plate 104, and a fixing plate 107 that can pass through the insert 404 is provided. The two ends of the fixing plate 107 are respectively attached to two hinge rods 106.
[0056] When the door 201 is opened, the two horizontal hinge rods 106 and the fixing plate 107 block the bottom groove 102 to prevent items or debris from entering the bottom groove 102.
