Abstract
Description
Technical Field
[0001] This application relates to the field of elevator technology, and in particular to an elevator door and an elevator. Background Technology
[0002] Existing elevator doors typically use fire-resistant insulated panels. These panels can block passage of people or objects, maintain door integrity for a certain period during a fire, and impede the passage of smoke and heat. However, current fire-resistant insulated panels usually use rock wool as insulation. Rock wool is a fibrous material that can irritate workers' skin, is difficult to fix, has poor insulation performance, and is not effective at blocking or delaying the passage of smoke. Therefore, improving the smoke-blocking and insulation performance of elevator doors is a pressing technical problem that needs to be solved. Utility Model Content

To this end, this application proposes an elevator door and an elevator that can improve the performance of the elevator door in blocking or delaying the passage of smoke and its heat insulation performance.
[0004] To achieve the above objectives, this application adopts the following technical solution:

[0038] The embodiments of this application will be further described below with reference to the accompanying drawings.
[0039] Reference Figure 1 , 2As shown in Figures 3, 4, and 5, the elevator door includes a door panel assembly 100, an upper baffle 200, a side baffle 300, and a lower baffle 400. The door panel assembly 100 is provided with a nano heat insulation board 110, and the surface of the nano heat insulation board 110 is provided with fireproof cotton. One end of the upper baffle 200 is connected to the top of the door panel assembly 100, and the other end of the upper baffle 200 is bent downward to form a first bending part 210. A first engagement area 220 is formed between the first bending part 210 and the front surface of the door panel assembly 100. The first engagement area 220 is used to engage with the lintel 500 to block smoke. One end of the side baffle 300 is connected to one side surface of the door panel assembly 100, and the other end of the side baffle 300 is bent away from the door panel assembly 100 to form a second bending part 310. The second bending part 310 is provided with a second engagement area 320. The second engagement area 320 is used to engage with the door frame post 510 to block smoke. One end of the lower baffle 400 is connected to the bottom of the door panel assembly 100, and the other end of the lower baffle 400 is used to engage with the sill 520.
[0040] In the above embodiment, the upper baffle 200, side baffle 300, and lower baffle 400 form a tight sealing area through precise engagement with the lintel 500, door frame pillar 510, and sill 520. The lintel 500 engages with the upper baffle 200 in the first engagement area 220, preventing smoke from diffusing upwards into the elevator; the door frame pillar 510 engages with the side baffle 300 in the second engagement area 320, preventing smoke from diffusing sideways into the elevator; and the sill 520 engages with one end of the lower baffle 400, preventing smoke from diffusing downwards into the elevator. Through these precise engagement structures, the elevator door can effectively prevent the spread of smoke during a fire, delaying the fire's spread and buying valuable time for evacuation. Regarding heat insulation, the door panel assembly 100 contains a nano-insulation board 110, a material with excellent thermal resistance properties that effectively isolates high-temperature transmission and reduces heat diffusion during a fire. Meanwhile, the surface of the nano-insulation board 110 is covered with a layer of fireproof cotton. This fireproof cotton effectively prevents the spread of flames and high temperatures, forming a heat insulation barrier and delaying the spread of fire. It also enhances the structure's sealing, preventing the penetration of smoke and flames. Furthermore, the fireproof cotton, through its expansion properties, seals cracks at high temperatures, further improving the safety of the elevator door. Compared with existing technologies, this embodiment, through its precise meshing structure and the installation of the nano-insulation board 110, improves the elevator door's ability to block or delay the passage of smoke, as well as its heat insulation performance.
[0041] For example, such as Figure 1 , 2As shown in Figures 3, 4, and 5, there are two door panel assemblies 100, one on the left and the other on the right. Taking the right-side door panel assembly 100 as an example, by embedding the upward-bent portion of the lintel 500 into the first bending area, the lintel 500 can engage with the upper baffle 200 to form a sealed area, preventing smoke from entering the elevator from above the door panel assembly 100. By embedding one end of the door frame post 510 into the second engagement area 320, when the door panel assembly 100 is in the closed state, the side baffle 300 engages with the door frame post 510 to form a sealed area, preventing smoke from entering the elevator from the side of the door panel assembly 100. By embedding the end of the lower baffle 400 facing the sill 520 into the groove of the sill 520, the lower baffle 400 engages with the sill 520 to form a sealed area, preventing smoke from entering the elevator from the bottom of the door panel assembly 100. The design of the left-side door panel assembly 100 is similar to that of the right-side door panel assembly 100.
[0042] Understandably, referring to Figure 1 , 2 As shown, the top of the door panel assembly 100 is provided with an upper end cap 120. The upper surface of the upper end cap 120 is connected to one end of the upper baffle 200, and the lower surface of the upper end cap 120 abuts against the top of the nano-insulation board 110. By providing the upper end cap 120 on the top of the door panel assembly 100, the overall sealing and heat insulation performance of the door panel can be effectively enhanced. The abutment between the lower surface of the upper end cap 120 and the top of the nano-insulation board 110 further enhances the heat insulation effect of the door panel, effectively blocks the transmission of high temperature, and improves the fire resistance of the door panel.
[0043] For example, such as Figure 1 , 2 As shown, the bottom of the upper baffle 200 is set as a plane and abuts against the top of the nano heat insulation board 110, so that the nano heat insulation board 110 is kept fixed, which improves the stability of the nano heat insulation board 110 in the door panel assembly 100, thereby improving the heat insulation performance.
[0044] Understandably, referring to Figure 1 , 2 As shown in Figure 6, the upper surface of the upper end cap 120 is provided with a first connecting hole 121. The first connecting hole 121 is used for external fasteners to pass through so that the upper baffle 200 is fixedly connected to the upper end cap 120. By having external fasteners pass through the first connecting hole 121 to firmly connect the upper baffle 200 to the upper end cap 120, the stability of the upper baffle 200 is improved, which helps to delay and block smoke from entering the elevator in the event of a fire, thereby improving safety.
[0045] The number of first connecting holes 121 is not limited in this application embodiment, and those skilled in the art can adjust it according to actual conditions. For example, Figure 1 , 2As shown in Figure 6, taking the setting of four first connecting holes 121 as an example, the four first connecting holes 121 are arranged horizontally aligned. The spacing between the two first connecting holes 121 near the left side of the door panel assembly 100 is equal to the spacing between the two first connecting holes 121 near the right side of the door panel assembly 100. The upper baffle 200 and the upper end cap 120 are fixedly connected by four external fasteners passing through the four first connecting holes 121 respectively, which improves the stability of the upper baffle 200 and helps to delay and block smoke from entering the elevator in the event of a fire, thereby improving safety. In some embodiments, the external fasteners may be self-tapping screws 330.
[0046] Understandably, referring to Figure 1 , 2 As shown, the bottom of the door panel assembly 100 is provided with a lower end cap 130, the bottom of which is connected to one end of the lower baffle 400, and the upper surface of the lower end cap 130 abuts against the bottom of the nano-insulation board 110. By providing the lower end cap 130 at the bottom of the door panel assembly 100, the overall sealing and heat insulation performance of the door panel can be effectively enhanced. The abutment between the upper surface of the lower end cap 130 and the bottom of the nano-insulation board 110 further improves the heat insulation effect of the door panel, effectively isolates high temperature transmission, and enhances the fire resistance of the door panel.
[0047] For example, such as Figure 1 , 2 As shown, the top of the lower end cap 130 is flat and abuts against the bottom of the nano-insulation plate 110, enabling the nano-insulation plate 110 to remain stable. The bottom of the lower end cap 130 protrudes towards the side of the door panel assembly 100, forming a protrusion that can be fixedly connected to one end of the lower baffle 400. The overall structural design of the lower end cap 130 not only saves materials but also reduces processing costs while achieving the required functions.
[0048] Understandably, referring to Figure 1 , 2 As shown in Figure 7, the bottom of the lower end cap 130 is provided with a second connecting hole 131. The second connecting hole 131 is used for external fasteners to pass through so that the lower baffle 400 is fixedly connected to the lower end cap 130. By having external fasteners pass through the second connecting hole 131 to firmly connect the lower baffle 400 to the lower end cap 130, the stability of the lower baffle 400 is improved, which helps to delay and block smoke from entering the elevator in the event of a fire, thereby improving safety.
[0049] For example, such as Figure 1 , 2As shown in Figure 7, taking the setting of four second connecting holes 131 as an example, the four second connecting holes 131 are arranged horizontally aligned, wherein the interval between the two second connecting holes 131 on the left side and the interval between the two second connecting holes 131 on the right side are equal. The lower baffle 400 is fixedly connected to the lower end cap 130 by four external fasteners passing through the four second connecting holes 131, which improves the stability of the lower baffle 400 and helps to delay and block smoke from entering the elevator in the event of a fire, thereby improving safety. In some embodiments, the external fasteners may be self-tapping screws 330.
[0050] Understandably, one end of the side baffle 300 is detachably connected to one side surface of the door panel assembly 100. This detachable connection between the side baffle 300 and the door panel assembly 100 improves the efficiency of elevator door installation.
[0051] Understandably, referring to Figure 1 As shown, one end of the side baffle 300 is fixedly connected to one side surface of the door panel assembly 100 by self-tapping screws 330. Fixing the side baffle 300 and the door panel assembly 100 by self-tapping screws 330 improves the stability of the structure.
[0052] Understandably, referring to Figure 1 As shown, the door panel assembly 100 also includes a reinforcing rib 140. One side of the reinforcing rib 140 is connected to the inner side of the door panel assembly 100, and the other side of the reinforcing rib 140 abuts against the nano-insulation board 110. The reinforcing rib 140 effectively enhances the structural strength and stability of the door panel assembly 100. The abutment between one side of the reinforcing rib 140 and the nano-insulation board 110 keeps the nano-insulation board 110 fixed inside the door panel, preventing it from shifting or deforming under high-temperature conditions.
[0053] The embodiments of this application do not limit the number of reinforcing ribs 140, and those skilled in the art can adjust them according to actual conditions. For example, Figure 1 As shown, taking the example of setting three reinforcing ribs 140, the three reinforcing ribs 140 include a front reinforcing rib 140, a first side reinforcing rib 140, and a second side reinforcing rib 140. The front reinforcing rib 140 is located in the center of the door panel assembly 100, the first side reinforcing rib 140 is located on the left side of the door panel assembly 100, and the second side reinforcing rib 140 is located on the right side of the door panel assembly 100. By setting three reinforcing ribs 140, the structural strength and stability of the door panel assembly 100 can be effectively enhanced.
[0054] Understandably, referring to Figure 1As shown, the door panel assembly 100 also includes a horizontal pressure plate 150. The horizontal pressure plate 150 is located on the side of the nano-insulation board 110 away from the reinforcing rib 140. The horizontal pressure plate 150 is used to press the fireproof cotton tightly against the surface of the nano-insulation board 110. The horizontal pressure plate 150 can effectively press the fireproof cotton tightly against the surface of the nano-insulation board 110, so that the fireproof cotton can adhere tightly to the nano-insulation board 110, thereby improving the fireproof effect.
[0055] The number of horizontal pressure plates 150 is not limited in this application embodiment, and those skilled in the art can adjust it according to actual conditions. For example, Figure 1 As shown, taking an example with two door panel assemblies 100 and eight horizontal pressure plates 150, the two door panel assemblies 100 include a left door panel assembly 100 and a right door panel assembly 100. Each of the left and right door panel assemblies 100 has four horizontal pressure plates 150. Taking the left door panel assembly 100 as an example, both ends of the horizontal pressure plates 150 are fixedly connected to both sides of the nano-insulation board 110 by screws. The four horizontal pressure plates 150 are aligned. The four horizontal pressure plates 150 enable the fireproof cotton to adhere tightly to the surface of the nano-insulation board 110, improving the fireproof effect.
[0056] The elevator of the second aspect of this application includes the elevator door of the first aspect of this application, which improves safety in the event of a fire.
[0057] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
