Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting hidden doors, in particular to an extra-large double-axis multi-directional hidden door. Background Art

[0002] Fire evacuation passage is a passage used for evacuation. In order to ensure the fire evacuation function, a secret door must be left open and cannot be blocked. This super-large double-axis multi-directional secret door is a secret door used in fire evacuation passages.

[0003] Conventional hidden doors can only be opened to about 90°. If the hidden door is constructed in two parts like the fire door, it will destroy the integrity of the wall and the door, affect the design effect, and reduce the look and feel. In addition, the fire hydrant hidden door can only be opened to 120°, which is difficult to meet the actual evacuation passage requirements of about 1800mm in width. In order to ensure that the door width is not too wide, thereby increasing the deadweight of the door body, and meet the 1800mm evacuation passage requirements and reduce the door gap to achieve the decorative effect, this project uses double-channel sky and earth axis hidden doors for axial, longitudinal and transverse opening.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] See also Figure 1-2 The utility model provides a technical solution for an extra-large double-axis multi-directional hidden door:

[0021] Embodiment 1:

[0022] like Figure 1-2As shown, an extra-large double-axis multi-directional secret door comprises a wall 1, a secret door passage 2 is opened at the end wall of the wall 1, a stainless steel shaft 3 is installed at the end wall of the wall 1 on one side close to the secret door passage 2, a front mechanical arm 4 is installed on the side of the stainless steel shaft 3 away from the wall 1, a rear mechanical arm 5 is installed at the right end of the front mechanical arm 4, two stainless steel shafts 6 are installed at the right end of the rear mechanical arm 5, a secret door 7 is installed on the side of the two stainless steel shafts 6 away from the rear mechanical arm 5, and a wall decoration 8 is arranged at the front end of the secret door 7.

[0023] Embodiment 2:

[0024] Based on the first embodiment, Figure 1 and Figure 2 As shown, the shape and structure of the hidden door passage 2 are consistent with the shape and structure of the wall decoration 8. The hidden door 7 and the wall decoration 8 are fixedly connected by bolts. The wall 1 is rotatably connected to the front mechanical arm 4 through a stainless steel shaft 3, and the front mechanical arm 4 is fixedly connected to the rear mechanical arm 5. The wall decoration 8 is used to decorate the hidden door 7. When the hidden door 7 is in the tube wall state, the wall decoration 8 and the wall 1 are consistent with each other in graphics and text, which are used to decorate the wall 1 and improve the aesthetics of the hidden door passage 2. At the same time, a stainless steel shaft 3 is used to rotate the front mechanical arm 4, so that the front mechanical arm 4, the rear mechanical arm 5, the decorative hidden door 7, and the wall decoration 8 are rotated, and the two stainless steel shafts 6 are rotated to rotate the decorative hidden door 7 and the wall decoration 8. The stainless steel shaft 3 and The two sections of stainless steel shaft 6 rotate together to rotate the hidden door 7 and wall decoration 8, so that the hidden door 7 and wall decoration 8 can be opened in three sections, axially, longitudinally and horizontally, so as to adapt to the 1800mm hidden door passage 2. At the same time, in this design, the shaft is installed on the inside of the door body. Compared with the entire hidden door, it is an eccentric structure. Under the condition of dead weight, the door body will tilt outward. The installation form of tilting inward by 5° is adopted to adjust the center of gravity of the door body to the middle position to ensure that the hidden door 7 can be completely closed in a natural state. If the dead weight of the door body is too large, a universal wheel can also be installed under the door body as a support. At all bolt installation locations, the steel drilling holes are opened according to twice the bolt diameter, and adjusted back and forth to eliminate installation errors and meet the use conditions;

[0025] Based on the first embodiment, Figure 1 and Figure 2 As shown, the front mechanical arm 4 and the rear mechanical arm 5 form an L shape, and the rear mechanical arm 5 is rotatably connected to the secret door 7 through two sections of stainless steel shafts 6. The front mechanical arm 4 and the rear mechanical arm 5 cooperate to form an L shape, which is convenient for the two sections of stainless steel shafts 6 and the one section of stainless steel shaft 3 to perform axial, longitudinal and transverse three-stage opening and rotation. The mechanical arm formed by the front mechanical arm 4 and the rear mechanical arm 5 is a 40*60*4mm hot-dip galvanized square tube mechanical arm with strong structural rigidity to adapt to the load-bearing capacity of the door body. The door body of the secret door 7 is a 40*60*4mm hot-dip galvanized square tube steel frame door body with strong structural rigidity.

[0026] Working principle: the wall decoration 8 is used to decorate the hidden door 7. When the hidden door 7 is in the tube wall state, the wall decoration 8 is consistent with the wall 1, which is used to decorate the wall 1 and improve the aesthetics of the hidden door passage 2. At the same time, a stainless steel shaft 3 is used to rotate the front mechanical arm 4, so that the front mechanical arm 4, the rear mechanical arm 5, the decorative hidden door 7, and the wall decoration 8 rotate, and the second stainless steel shaft 6 rotates to rotate the decorative hidden door 7 and the wall decoration 8. The first stainless steel shaft 3 and the second stainless steel shaft 6 rotate together to rotate the hidden door 7 and the wall decoration 8, so that the hidden door 7 and the wall decoration 8 can be opened in three sections axially, longitudinally and horizontally, so as to adapt to the 1800mm hidden door passage 2. At the same time, in this design, the shaft is installed on the inside of the door body. Relative to the entire hidden door, it is an eccentric structure. Under its own weight, the door body will tilt outwards. Use the installation form of tilting 5° inward to adjust the center of gravity of the door to the middle position to ensure that the hidden door 7 can be completely closed in a natural state. If the weight of the door body is too large, universal wheels can also be installed under the door body as support. At all bolt installation locations, steel holes are drilled according to twice the diameter of the bolts and adjusted back and forth to eliminate installation errors and meet the conditions of use. The front mechanical arm 4 and the rear mechanical arm 5 are coordinated to form an L-shaped shape, which is convenient for two stainless steel shafts 6 and one stainless steel shaft 3 to perform axial, longitudinal and transverse three-stage opening and rotation. The mechanical arm composed of the front mechanical arm 4 and the rear mechanical arm 5 is a 40*60*4mm hot-dip galvanized square tube mechanical arm with strong structural rigidity to adapt to the load-bearing capacity of the door body. The door body of the hidden door 7 is a 40*60*4mm hot-dip galvanized square tube steel frame door body with strong structural rigidity.
