Description

Technical Field

[0001] This application relates to the field of emergency doors, and more particularly to an aluminum alloy emergency door. Background Technology

[0002] Emergency doors are an important part of building fire protection. They are normally closed doors used at the entrances and exits of fire escape routes in buildings to prevent the spread of flames and smoke. They need to be able to be opened during escape to evacuate people in the event of a fire, and also need to be closed at any time to prevent the fire from spreading.

[0003] Currently, most emergency doors in buildings are normally closed by installing door closers. The door closer is a hydraulic or spring device with a linkage, usually installed on the upper part of the door. After a person pushes open the emergency door and goes out, the door closer uses the hydraulic or spring device to drive the linkage to close the door again. Although this can meet the needs of fire safety, because the emergency door of the fire escape is not locked, it can be opened from both the inside and the outside, which may create theft and robbery risks and make it impossible to guarantee the safety of property inside the building. Utility Model Content

[0004] To address the aforementioned issues, this application provides an aluminum alloy emergency door.

[0005] The aluminum alloy emergency door provided in this application adopts the following technical solution:

[0006] An aluminum alloy emergency door includes a door frame and a door panel body. The door frame and the door panel body are provided with mounting components for quick installation of the door panel body. The door panel body is provided with a blocking component for restricting the opening of the door panel body. The blocking component includes a fixing sleeve fixedly connected to one side of the door panel body. A locking plate is slidably disposed in the fixing sleeve. The side wall of the locking plate away from the fixing sleeve is abutted against the side wall of the door frame. A limiting plate for restricting the opening direction of the door panel body is fixedly connected to one side wall of the door frame.

[0007] By adopting the above technical solution, when in use, the door frame is installed at the fire escape, and then the door panel is installed on the door frame using the installation components. To open, simply slide the locking plate to move it into the fixed sleeve, and then push the door panel. At the same time, the opening direction of the door panel is restricted by the limiting plate, which can only be pushed open from the inside to the outside. This avoids the possibility of theft and robbery that could occur if the door can be opened from the inside or the outside, thus preventing the loss of property security within the building.

[0008] Preferably, the installation assembly includes a fixed rod fixedly connected to the inner side of the door frame, a rotating column sleeved on the fixed rod, and connecting blocks fixedly connected to both ends of the rotating column. One end of the door panel body is located between two of the connecting blocks. The upper and lower sides of the side wall of the door panel body near the limiting plate are provided with installation grooves. Multiple installation rods are provided in the installation grooves. One end of the installation rod passes through the side wall of the installation groove and is inserted into the connecting block respectively. The other end of the installation rod is slidably disposed on the other side wall of the installation groove. Each installation rod is threaded with two fastening sleeves.

[0009] By adopting the above technical solution, one end of the door panel body is placed between two connecting blocks, and then the mounting rod is slid to insert into the connecting block. Then, the two fastening sleeves are rotated to make the fastening sleeves abut against the two side walls of the mounting groove, thereby fixing the mounting rod and fixing the door panel body to one side of the rotating column, thus installing the door panel body.

[0010] Preferably, the inner side of the door frame has two receiving slots for accommodating the connecting blocks.

[0011] By adopting the above technical solution, the connecting block can be hidden through the receiving groove, preventing the connecting block from being located between the door frame and the door panel body, which would result in an excessively large gap between the door frame and the door panel body.

[0012] Preferably, a door closer is installed between the door frame and the door panel body.

[0013] By adopting the above technical solution, the door closer can automatically move the door panel into the door frame and close it after a person opens the door panel and leaves.

[0014] Preferably, the fixing sleeve is provided with multiple springs, and the two ends of the springs are respectively fixedly connected to the fixing sleeve and the locking plate. One side wall of the locking plate is arc-shaped.

[0015] By adopting the above technical solution, when the door closer closes the door panel, the arc-shaped locking plate will push the locking plate into the fixed sleeve when it comes into contact with the door frame, compressing the spring. Then, when the locking plate is removed from the door frame, the spring will rebound and push the locking plate out, locking the door panel.

[0016] Preferably, a groove is provided on one side wall of the fixing sleeve, and a slider is fixedly connected to one side wall of the locking plate, the slider being slidably disposed in the groove.

[0017] By adopting the above technical solution, the locking plate can be easily moved into the fixed sleeve by sliding the slider in the groove.

[0018] Preferably, each spring is provided with a guide rod, one end of which is fixedly connected to the fixed sleeve, and the other end of which is slidably disposed with the locking plate.

[0019] By adopting the above technical solution, the stability of the spring can be improved through the guide rod.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application utilizes the cooperative arrangement of structures such as a fixed sleeve, a locking plate, and a limiting plate. In use, the door frame is installed at the fire escape route, and then the door panel is installed onto the door frame using the installation components. To open, simply slide the locking plate to move it into the fixed sleeve, and then push the door panel. At the same time, the limiting plate restricts the opening direction of the door panel, allowing it to be pushed open only from the inside out. This minimizes the risk of theft and robbery that could occur if the door could be opened from the inside or the outside, thus compromising the security of property within the building.

[0022] 2. By placing one end of the door panel body between the two connecting blocks, and then sliding the mounting rod to insert it into the connecting block, and then rotating the two fastening sleeves to make the fastening sleeves abut against the two side walls of the mounting groove, the mounting rod is fixed, and the door panel body is fixed on one side of the rotating column, making it convenient to install and remove the door panel body.

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0030] This application discloses an aluminum alloy emergency door.

[0031] Reference Figure 1 An aluminum alloy emergency door includes a door frame 1 and a door panel body 2. The door frame 1 and the door panel body 2 are provided with mounting components for quick installation of the door panel body 2. The door panel body 2 is provided with a blocking component for restricting the opening of the door panel body 2. The blocking component includes a fixing sleeve 3, a locking plate 4 and a limiting plate 5.

[0032] The fixing sleeve 3 is fixedly connected to one side of the door panel body 2. The locking plate 4 is slidably disposed inside the fixing sleeve 3 and one end of the locking plate 4 passes through the fixing sleeve 3. The side wall of the locking plate 4 away from the fixing sleeve 3 is in contact with the side wall of the door frame 1, which is used to restrict the door panel body 2 from opening to one side of the door frame 1. The limiting plate 5 is fixedly connected to the side wall of the door frame 1 near the fixing sleeve 3. The limiting plate 5 is away from the locking plate 4 and one side wall is in contact with the door panel body 2, which is used to restrict the door panel body 2 from opening to the other side of the door frame 1.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The installation assembly includes a fixed rod 6 fixedly connected to the inner side of the door frame 1. A rotating column 7 is sleeved on the fixed rod 6. Connecting blocks 8 are fixedly connected to both ends of the rotating column 7. One end of the door panel body 2 is located between the two connecting blocks 8. The upper and lower sides of the side wall of the door panel body 2 near the limiting plate 5 are provided with installation grooves 9. Multiple installation rods 10 are provided in the installation grooves 9. One end of the installation rod 10 passes through the side wall of the installation groove 9 and is inserted into the connecting block 8 respectively. The other end of the installation rod 10 is slidably set on the other side wall of the installation groove 9. Two fastening sleeves 11 are threadedly connected to each installation rod 10. One end of the door panel body 2 is placed between the two connecting blocks 8. Then the installation rod 10 is slid to insert into the connecting block 8. Then the two fastening sleeves 11 are rotated respectively to make the fastening sleeves 11 abut against the two side walls of the installation groove 9, fixing the installation rod 10 and fixing the door panel body 2 to one side of the rotating column 7, which facilitates the installation and disassembly of the door panel body 2.

[0034] Reference Figure 2 The inner side of the door frame 1 has two receiving grooves 12 for accommodating the connecting block 8. The connecting block 8 can be hidden by the receiving grooves 12 to prevent the connecting block 8 from being located between the door frame 1 and the door panel body 2, which would cause the gap between the door frame 1 and the door panel body 2 to be too large.

[0035] Reference Figure 4A door closer 13 is installed between the door frame 1 and the door panel body 2. The door closer 13 can automatically move the door panel body 2 into the door frame 1 to close it after a person opens the door panel body 2 and goes out.

[0036] Reference Figure 5 The fixed sleeve 3 is equipped with multiple springs 14. The two ends of the springs 14 are fixedly connected to the fixed sleeve 3 and the locking plate 4 respectively. One side wall of the locking plate 4 is arc-shaped. When the door closer 13 closes the door panel body 2, the arc-shaped locking plate 4 will push the locking plate 4 into the fixed sleeve 3 when it comes into contact with the door frame 1, thus squeezing the springs 14. Then, when the locking plate 4 is separated from the door frame 1, the spring 14 rebounds and pushes the locking plate 4 out, locking the door panel body 2.

[0037] Reference Figure 1 The fixed sleeve 3 has a groove 15 on one side wall, and the locking plate 4 has a slider 16 fixedly connected to one side wall. The slider 16 is slidably disposed in the groove 15. By sliding the slider 16 in the groove 15, the locking plate 4 can be easily moved into the fixed sleeve 3.

[0038] Reference Figure 5 Each spring 14 is equipped with a guide rod 17. One end of the guide rod 17 is fixedly connected to the fixed sleeve 3, and the other end of the guide rod 17 is slidably set with the locking plate 4. The stability of the spring 14 can be improved by the guide rod 17.

[0039] The implementation principle of an aluminum alloy emergency door according to this application embodiment is as follows: In use, the user first installs the door frame 1 in the fire escape route, then places one end of the door panel body 2 between two connecting blocks 8, slides the mounting rod 10 to insert it into the connecting block 8, and then rotates the two fastening sleeves 11 to abut against the side walls of the mounting groove 9, fixing the mounting rod 10 and securing the door panel body 2 to one side of the rotating column 7. The door panel body 2 is then installed. When opened, the opening direction of the door panel body 2 is restricted by the limiting plate 5, allowing it to open only from one side via the sliding locking plate. 4. Move the locking plate 4 into the fixed sleeve 3, then push the door panel 2 to open. Then, the door closer 13 can automatically move the door panel 2 into the door frame 1 after the person opens the door panel 2 and goes out. When the arc-shaped locking plate 4 comes into contact with the door frame 1, it will push the locking plate 4 into the fixed sleeve 3 and squeeze the spring 14. Then, when the locking plate 4 is separated from the door frame 1, the spring 14 rebounds and pushes the locking plate 4 out, locking the door panel 2. This avoids the possibility that the inside can be opened while the outside can be opened at the same time, which may cause theft and robbery and make it impossible to guarantee the security of property inside the building.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
