Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, and in particular to a basement hidden door with high stability. Background Technology

[0002] In the field of building safety facilities, basement concealed doors are important components for ensuring the concealment and safety of underground spaces. The rationality of their structural design directly affects their usability. Traditional basement concealed doors have significant shortcomings in terms of door panel movement control and locking mechanisms. On the one hand, some concealed doors lack effective buffering and limiting structures. During the opening and closing process, due to the lack of buffer devices, the door panel is prone to generating large impact forces, causing the door panel to shake or even collide with the door frame. This not only generates noise but also accelerates the wear and tear of the door panel and door frame, shortening the service life of the concealed door. At the same time, without reliable limiting measures, the door panel may rotate excessively, causing damage to the concealed door structure and affecting its normal use and safety performance. On the other hand, the existing locking structures of concealed doors mostly use simple bolts or latches, which are difficult to provide sufficient resistance when facing external impacts or prying, and cannot effectively ensure the safety of the basement. Therefore, it is necessary to redesign a basement concealed door with high stability to address the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly stable basement hidden door.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A highly stable basement concealed door includes a door frame. Two support legs and two support plates are fixedly installed on the bottom wall of the door frame. A door panel is rotatably installed inside the door frame. Electro-hydraulic rods are fixedly installed on the upper surfaces of both support plates via a connecting mechanism. Two fixing plates and two fixing ears are fixedly installed on the inner wall of the door panel. Connecting openings are provided at the telescopic ends of both electro-hydraulic rods. The two fixing plates are rotatably connected to the connecting openings on the same side. Springs are fixedly installed on the upper surfaces of both support plates. The ends of the two springs are elastically connected to the fixing ears on the same side. The door panel... The wall has a movable groove, and a first connecting frame is fixedly connected inside the movable groove via a telescopic mechanism. A sliding rod is fixedly installed inside the movable groove. Two sliders are slidably installed on the outer wall of the sliding rod via a stabilizing mechanism. A second connecting frame is fixedly installed on the inner wall of each of the two sliders. The first connecting frame is rotatably connected to the two second connecting frames via a connecting mechanism. An insert plate is fixedly installed on the outer wall of each of the two sliders. Movable openings that cooperate with the insert plates are opened on both outer walls of the door panel. Slots that cooperate with the insert plates are fixedly installed on both inner walls of the door frame. Two limiting plates are fixedly installed on the inner wall of the door frame.

[0006] Preferably, the connecting mechanism includes a connecting plate fixedly installed on the upper surface of the support plate, a connecting frame rotatably installed on the outer wall of the connecting plate, and an electro-hydraulic rod fixedly installed on the upper surface of the connecting frame.

[0007] Preferably, the telescopic mechanism includes an electric actuator fixedly installed inside the movable slot, and the telescopic end of the electric actuator is fixedly connected to the outer wall of the first connecting frame.

[0008] Preferably, the stabilizing mechanism includes a stabilizing rod fixedly installed inside the movable groove, the stabilizing rod sliding through the two sliders.

[0009] Preferably, the connecting mechanism includes two connecting plates rotatably installed inside the first connecting frame, and the ends of the two connecting plates are respectively rotatably connected to the inside of the second connecting frame on the same side.

[0010] Preferably, iron chains are rotatably installed on the inner walls of both sides of the door frame via support rods, and the ends of the two iron chains are respectively fixedly connected to the fixing lugs on the same side.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting components such as fixed ears, springs and chains, the springs on the support plate will stretch with the movement of the fixed ears during the rotation of the door panel, which plays a role in buffering and auxiliary stabilization, reducing the impact and shaking generated when the door panel rotates. At the same time, the chains installed on the inner wall of the door frame through the support rod will unfold with the rotation of the door panel, which will limit the rotation range of the door panel to a certain extent and prevent the door panel from being damaged due to excessive rotation.

[0013] 2. By setting up components such as electric actuators, connecting plates, and insert plates, when the electric actuator extends, it can drive the slider to move through the cooperation of the connecting plate. This allows the slider to move the insert plate in the moving opening, thereby accurately pushing the insert plate into the slot and forming a tight mechanical locking structure. This effectively prevents the hidden door from being accidentally opened by external impact or prying, and significantly improves the safety performance of the basement. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5 A highly stable basement hidden door includes a door frame 1. Two support legs 2 and two support plates 3 are fixedly installed on the bottom wall of the door frame 1. A door panel 4 is rotatably installed inside the door frame 1. Electro-hydraulic rods 7 are fixedly installed on the upper surfaces of the two support plates 3 through a connecting mechanism. The connecting mechanism includes a connecting plate 5 fixedly installed on the upper surface of the support plate 3. A connecting frame 6 is rotatably installed on the outer wall of the connecting plate 5. The electro-hydraulic rods 7 are fixedly installed on the upper surface of the connecting frame 6. Two fixing plates 8 and two fixing ears 9 are fixedly installed on the inner wall of the door panel 4. The telescopic ends of the two electro-hydraulic rods 7 are provided with connecting openings. The two fixing plates 8 are rotatably connected to the connecting openings on the same side. Springs 10 are fixedly installed on the upper surfaces of the two support plates 3. The ends of the two springs 10 are elastically connected to the fixing ears 9 on the same side. Iron chains 12 are rotatably installed on the inner walls of both sides of the door frame 1 through support rods 11. The ends of the two iron chains 12 are fixedly connected to the fixing ears 9 on the same side.

[0022] The inner wall of the door panel 4 has a movable groove. A first connecting frame 14 is fixedly connected inside the movable groove through a telescopic mechanism. The telescopic mechanism includes an electric push rod 13 fixedly installed inside the movable groove. The telescopic end of the electric push rod 13 is fixedly connected to the outer wall of the first connecting frame 14. A slide rod 15 is fixedly installed inside the movable groove. Two sliders 17 are slidably installed on the outer wall of the slide rod 15 through a stabilizing mechanism. The stabilizing mechanism includes a stabilizing rod 16 fixedly installed inside the movable groove. The stabilizing rod 16 slides through the two sliders 17 and can restrict the two sliders 17 so that the two sliders 17 can only move axially along the outer wall of the slide rod 15.

[0023] The inner walls of both sliders 17 are fixedly equipped with second connecting frames 18. The interior of the first connecting frame 14 is rotatably connected to the interior of the two second connecting frames 18 through a connecting mechanism. The connecting mechanism includes two connecting plates 19 rotatably installed inside the first connecting frame 14. The ends of the two connecting plates 19 are rotatably connected to the interior of the second connecting frames 18 on the same side. The outer walls of both sliders 17 are fixedly equipped with insert plates 20. The outer walls on both sides of the door panel 4 are provided with movable openings that cooperate with the insert plates 20. The inner walls on both sides of the door frame 1 are fixedly equipped with slots that cooperate with the insert plates 20. The inner walls of the door frame 1 are fixedly equipped with two limiting plates 21.

[0024] When using this utility model, the door frame 1 can be fixedly connected to the basement entrance to ensure that the door frame 1 is installed firmly and fits tightly with the entrance, avoiding gaps that would affect the concealment and security of the hidden door. After the door frame 1 is properly installed, the power supply of the electric hydraulic rod 7 and the electric push rod 13 is connected to complete the power-on preparation of the equipment. When it is necessary to open the basement hidden door, the operator can first start the electric push rod 13 through the control system. The telescopic end of the electric push rod 13 retracts, driving the first connecting frame 14 to move towards the side of the electric push rod 13 in the moving groove. Since the first connecting frame 14 is rotatably connected to the two second connecting frames 18 through the connecting plate 19, the movement of the first connecting frame 14 will cause the connecting plate 19 to rotate, thereby driving the two sliders 17 to slide closer to each other along the sliding rod 15. As the sliders 17 slide, the insert plate 20 installed on the outer wall of the slider 17 will be pulled out from the slots on both sides of the inner wall of the door frame 1. At this time, the locking state between the door panel 4 and the door frame 1 is released.

[0025] Next, the control system activates the electric hydraulic rod 7. The telescopic end of the electric hydraulic rod 7 extends. Because the connection opening of the telescopic end of the electric hydraulic rod 7 is rotatably connected to the fixed plate 8 on the inner wall of the door panel 4, the extension of the electric hydraulic rod 7 will push the door panel 4 to rotate outward around its rotatable connection with the door frame 1 and open. During the rotation of the door panel 4, the spring 10 on the support plate 3 will stretch with the movement of the door panel 4, playing a role in buffering and auxiliary stabilization, reducing the impact and shaking generated when the door panel 4 rotates. At the same time, the iron chain 12 rotatably installed on the inner wall of the door frame 1 through the support rod 11 will unfold with the rotation of the door panel 4, which will limit the rotation range of the door panel 4 to a certain extent and prevent the door panel 4 from being damaged due to excessive rotation.

[0026] When the basement hidden door needs to be closed, the operation sequence is reversed. First, activate the electric hydraulic rod 7 to shorten its telescopic end, pulling the door panel 4 inward around the rotating connection with the door frame 1. When the door panel 4 is almost fully closed, the spring 10 gradually returns to its original state, providing a buffer and reset assist for the closing action of the door panel 4. When the door panel 4 rotates to the position where it fits against the door frame 1, activate the electric push rod 13. The telescopic end of the electric push rod 13 extends, pushing the first connecting frame 14 to move in the opposite direction within the moving groove. This will cause the connecting plate 19 to... Rotating again causes the two sliders 17 to slide away from each other along the slide bar 15, thereby allowing the insert plate 20 to pass through the moving openings on both sides of the outer wall of the door panel 4 and insert into the slots on both sides of the inner wall of the door frame 1, thus locking the door panel 4 and the door frame 1 again. In addition, the two limiting plates 21 play a key limiting role in the closing process of the door panel 4. When the door panel 4 is fully closed, the limiting plates 21 will prevent the door panel 4 from continuing to rotate, ensuring that the door panel 4 moves within a reasonable range and ensuring the normal use and structural integrity of the hidden door.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
