Description

Technical Field

[0001] This utility model belongs to the field of elevator door technology, specifically relating to a novel elevator door structure. Background Technology

[0002] Elevator door structures mainly consist of a drive door panel and a driven door panel, which are linked together by a linkage mechanism to achieve synchronized opening and closing actions. The drive door panel, as the active component, is driven by a motor or other power device, causing the driven door panel to move in tandem, thus completing the opening and closing operation of the elevator door and meeting the needs of personnel and goods entering and exiting. This basic structure has been used in the elevator industry for a long time, providing a fundamental guarantee for the normal operation of elevators.

[0003] Existing fireproof elevator doors are ineffective at preventing toxic fumes and high-temperature smoke from entering the elevator shaft during a fire, affecting the normal use of the elevator. Furthermore, their insulation is insufficient and cannot fully guarantee the safety of users. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel elevator insulation door structure. The insulation cotton is supported and held in place by reinforcing ribs on the door panel, and reinforced supports on both sides prevent the insulation cotton from collapsing and losing its insulation properties under external pressure. Finally, an L-shaped pressure plate firmly presses the insulation cotton to prevent loosening while further increasing insulation performance. This solves the problem that existing elevator fireproof doors are unable to effectively prevent toxic smoke and high-temperature fumes from entering the elevator shaft during a fire, affecting the normal operation of the elevator, and that insufficient insulation fails to fully guarantee user safety.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel elevator door insulation structure, including a drive door panel assembly and a driven door panel assembly, with side fire baffles provided on the outer sides of the drive door panel assembly and the driven door panel assembly, and reinforcing seats provided at both ends of the drive door panel assembly and the driven door panel assembly, with L-shaped pressure plates installed on the reinforcing seats, and heat insulation cotton provided between the reinforcing seats and the L-shaped pressure plates.

[0006] Preferably, the drive door panel assembly includes a drive door panel, the outer side of which is fastened to the side fire baffle by bolts, and the inner side of the drive door panel is provided with a first extension extending outward.

[0007] Preferably, the driven door panel assembly includes a driven door panel, the outer side of which is fastened to the side fire baffle by bolts, and the inner side of the driven door panel is provided with a second extension that matches the first extension.

[0008] Preferably, the reinforcing seats on both sides of the drive door panel assembly and the driven door panel assembly are L-shaped reinforcing seats.

[0009] Preferably, the reinforcing seats on both sides of the drive door panel assembly and the driven door panel assembly are Z-shaped reinforcing seats.

[0010] Preferably, one side of the reinforcing seat of the driving door panel assembly and the driven door panel assembly is an L-shaped reinforcing seat, and the other side of the reinforcing seat of the driving door panel assembly and the driven door panel assembly is a Z-shaped reinforcing seat.

[0011] Preferably, reinforcing ribs are provided between the drive door panel and the driven door panel and the insulation cotton.

[0012] Preferably, a buffer is provided at the connection between the driving door panel and the driven door panel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the heat insulation cotton is supported by the reinforcing ribs on the door panel, and the heat insulation cotton is supported by reinforcing seats on both sides to prevent it from collapsing and losing its heat insulation properties when subjected to external pressure. Finally, the heat insulation cotton is firmly pressed down with an L-shaped pressure plate to prevent loosening, while further increasing the heat insulation properties. This ensures that in extreme situations such as fire, the door panel assembly will not be easily deformed or damaged due to high temperature or external force, thus maintaining the structural integrity of the elevator door.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of the invention. Attached Figure Description

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0022] Combination Figure 1 , Figure 2 and Figure 3 As shown, a novel elevator door insulation structure includes a drive door panel assembly 1 and a driven door panel assembly 2. Side fire baffles 3 are provided on the outer sides of the drive door panel assembly 1 and the driven door panel assembly 2. Reinforcing seats 4 are provided at both ends of the drive door panel assembly 1 and the driven door panel assembly 2. L-shaped pressure plates 5 are installed on the reinforcing seats 4. Heat insulation cotton 6 is provided between the reinforcing seats 4 and the L-shaped pressure plates 5.

[0023] This invention proposes a novel elevator door insulation structure. The drive door panel assembly 1 is the active drive component for opening and closing the elevator door. The driven door panel assembly 2 cooperates with the drive door panel assembly 1, and under the drive of the drive door panel assembly 1, the elevator door opens and closes. Together, they constitute the main structure of the elevator door. A side fire baffle 3 is located on the outside of the drive door panel assembly 1 and the driven door panel assembly 2, serving to block the spread of flames, enhance the fire resistance of the elevator door, and protect the interior space of the elevator from the impact of external fires.

[0024] The reinforcing seat 4 is installed at both ends of the driving door panel assembly 1 and the driven door panel assembly 2 to enhance the structural strength of the door panel assembly, improve the stability of the door panel during operation, and prevent the door panel from deforming due to stress or prolonged use. The L-shaped pressure plate 5 is installed on the reinforcing seat 4 and cooperates with it to fix and install the thermal insulation cotton 6. It may also provide some auxiliary reinforcement to the connection between the reinforcing seat 4 and the door panel assembly. The thermal insulation cotton 6 is placed between the reinforcing seat 4 and the L-shaped pressure plate 5 to prevent heat transfer, reduce the impact of high temperatures on the elevator interior during a fire, and further enhance the thermal insulation performance of the elevator door.

[0025] Under normal operating conditions, the drive door panel assembly 1 opens or closes under the command of the elevator control system, simultaneously driving the driven door panel assembly 2 to move synchronously, thus realizing the normal opening and closing function of the elevator door. At this time, the side fire baffle 3, the reinforcing seat 4, the L-shaped pressure plate 5, and the heat insulation cotton 6 mainly play a structural support and auxiliary role, ensuring the stability and reliability of the elevator door operation.

[0026] In the event of a fire, the side fire baffle 3 effectively prevents flames from spreading from the outside of the elevator door to the inside, giving occupants more time to escape. Simultaneously, the insulation cotton 6 prevents high-temperature heat from being transferred to the elevator interior through structural components such as the reinforcing seat 4, slowing the rate of temperature increase inside the elevator and protecting the equipment and personnel. The reinforcing seat 4 ensures that, in extreme situations such as a fire, the door panel assembly will not easily deform or be damaged due to high temperatures or external forces, maintaining the structural integrity of the elevator door.

[0027] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the drive door panel assembly 1 includes a drive door panel 11. The outer side of the drive door panel 11 is fastened to the side fire baffle 3 by bolts, and the inner side of the drive door panel 11 is provided with an outwardly extending first extension 12.

[0028] Specifically, the drive door panel 11 serves as the basic frame and support, and its outer side is fastened to the side fire baffle 3 with bolts. This ensures that the side fire baffle 3 is securely installed on the drive door panel 11. In the event of a fire, the side fire baffle 3 effectively prevents flames and heat from spreading from the outside of the elevator door to the inside, providing fire protection for the elevator interior. The inner side of the drive door panel 11 is provided with a first extension 12 extending outwards. The first extension 12 protrudes outwards from the inner surface of the drive door panel 11.

[0029] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the driven door panel assembly 2 includes a driven door panel 21. The outer side of the driven door panel 21 is fastened to the side fire baffle 3 by bolts. The inner side of the driven door panel 21 is provided with a second extension 22 that matches the first extension 12.

[0030] Specifically, the driven door panel 21 serves as the basic frame and support, and its outer side is bolted to the side fire baffle 3. This allows the side fire baffle 3 to be securely mounted on the driven door panel 21, working together with the side fire baffle 3 on the drive door panel assembly 1 to form a continuous fire barrier on the outer side of the elevator door. The inner side of the driven door panel 21 is provided with a second extension 22 that matches the first extension 12. The second extension 22 extends outward from the inner surface of the driven door panel 21 and can cooperate with the first extension 12 on the drive door panel assembly 1. This enables functions such as linkage between door panels, positioning, or enhancing the overall structural strength.

[0031] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, both sides of the reinforcing seats 4 of the driving door panel assembly 1 and the driven door panel assembly 2 are L-shaped reinforcing seats 41.

[0032] Specifically, the L-shaped reinforcing seat 41 has a right-angled "L" shape, providing structural support in two mutually perpendicular directions. Its two sides can be connected and fixed to different parts of the door panel assembly, enhancing the stability and versatility of the connection. It is installed on both sides of the driving door panel assembly 1 and the driven door panel assembly 2. Installed at the edge of the door panel assembly, it effectively reinforces the sides of the door panel, preventing lateral deformation due to uneven force or external impact during opening and closing.

[0033] Combination Figure 1 , Figure 2 and Figure 3 As shown, both sides of the reinforcing seats 4 of the driving door panel assembly 1 and the driven door panel assembly 2 are Z-shaped reinforcing seats 42.

[0034] Specifically, the Z-shaped reinforcing seat 42 has a unique "Z" shape, composed of three sections of plates connected perpendicularly or at a certain angle. It exhibits excellent mechanical properties in multiple directions, effectively dispersing and transferring stress under different load conditions. The horizontal section typically fits tightly against the edge of the door panel and is fixed to the door panel using bolts or other connectors, providing a stable mounting base for the reinforcing seat 4 and ensuring no relative displacement between the reinforcing seat 4 and the door panel. The vertical section connects the two horizontal sections, increasing the overall height and rigidity of the reinforcing seat 4. The vertical section resists lateral forces, preventing the door panel from bending under lateral loads. The other horizontal section can extend to other parts of the door panel or connect to adjacent structural components, further expanding the load-bearing range of the reinforcing seat 4 and enhancing the structural stability of the entire door panel system.

[0035] Combination Figure 3 , Figure 4 and Figure 5 As shown, the reinforcing seat 4 on one side of the driving door panel assembly 1 and the driven door panel assembly 2 is an L-shaped reinforcing seat 41, and the reinforcing seat 4 on the other side of the driving door panel assembly 1 and the driven door panel assembly 2 is a Z-shaped reinforcing seat 42.

[0036] Specifically, the L-shaped reinforcing seat 41 is shaped like a right-angled "L" and consists of two mutually perpendicular plates. It provides structural support in two vertical directions. It is installed on one side of the driving door panel assembly 1 and the driven door panel assembly 2. One plate is tightly fitted to the edge plane of the door panel and firmly fixed by bolts or other connectors, providing a stable mounting base for the reinforcing seat 4; the other plate extends outward perpendicular to the edge of the door panel, which can enhance the strength and rigidity of the side of the door panel and resist lateral forces.

[0037] The Z-shaped reinforcing seat 42 has a unique "Z"-shaped appearance and is composed of three sections of plates connected perpendicularly or at a certain angle. It exhibits excellent mechanical properties in multiple directions, effectively distributing and transferring stress. It is installed on the opposite side of the driving door panel assembly 1 and the driven door panel assembly 2. Two horizontal sections are respectively fitted and fixed to different parts of the door panel, while the vertical section connects these two horizontal sections, increasing the overall height and rigidity of the reinforcing seat 4. It can resist forces from different directions, preventing the door panel from deforming under complex stress conditions.

[0038] Combination Figure 3 , Figure 4 and Figure 5 As shown, reinforcing ribs 7 are provided between the drive door panel 11 and the driven door panel 21 and the heat insulation cotton 6.

[0039] Specifically, the reinforcing rib 7 typically adopts a long strip structure, providing a larger support area and better mechanical properties. Its cross-section may be rectangular, trapezoidal, or other shapes suitable for stress distribution. The layout of the reinforcing rib 7 on the driving door panel 11 and the driven door panel 21 is not arbitrary, but designed according to the stress conditions and structural characteristics of the door panels. Generally, it may be evenly distributed along the length or width direction of the door panel, or it may be densely arranged in certain areas of concentrated stress.

[0040] The reinforcing ribs 7 are typically fixed to the drive door panel 11 and the driven door panel 21 by welding, riveting, or bolting. The reinforcing ribs 7 and the insulation cotton 6 are generally tightly fitted together. The insulation cotton 6 can fill the gaps between the reinforcing ribs 7 or wrap around the surface of the reinforcing ribs 7. This not only ensures the stable installation of the insulation cotton 6 but also ensures that the reinforcing ribs 7, while enhancing the structural strength of the door panel, do not significantly affect the heat insulation effect of the insulation cotton 6.

[0041] Combination Figure 3 , Figure 4 and Figure 5 As shown, a buffer 8 is provided at the connection between the drive door panel 11 and the driven door panel 21.

[0042] Specifically, the buffer component 8 comes in various shapes, commonly including cylindrical, cuboid, and rubber block shapes. The cylindrical buffer component 8 has a simple structure, is easy to install, and can provide a certain degree of cushioning in all directions; the cuboid buffer component 8 can be customized according to the spatial shape of the connection point to better fit the door panel connection area and provide a more stable cushioning effect; the rubber block buffer component 8 has good elasticity and deformation capacity and can adapt to impact forces of different sizes.

[0043] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
