Description

Technical Field

[0001] This utility model relates to the field of sightseeing elevator technology, specifically to an anti-deformation elevator door. Background Technology

[0002] A sightseeing elevator is a special type of elevator designed to allow passengers to enjoy the scenery outside while riding. These elevators are usually equipped with transparent car walls and shaft walls, allowing passengers to view the surrounding environment as they move up and down. In addition, to enhance the passenger's sightseeing experience, the doors of sightseeing elevators are mostly made of glass.

[0003] Due to the material properties of sightseeing elevators, they are at risk of deformation when exposed to sunlight for extended periods of use. Existing solutions mostly involve coating the outer surface of the glass to improve sun protection. However, a single coating treatment has limited effectiveness in preventing sun damage and deformation. Furthermore, the glass surfaces near the elevator interior may accumulate grease or dust during use, making them difficult to clean. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-deformation elevator door to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant elevator door, comprising sun-proof glass, with laminated glass at the rear end of the sun-proof glass and dirt-resistant glass at the rear end of the laminated glass. The top and bottom ends of the sun-proof glass, laminated glass, and dirt-resistant glass are all connected to a fixed frame. Side frames are provided on both sides of the sun-proof glass, laminated glass, and dirt-resistant glass. Positioning frames matching the laminated glass are provided at opposite ends of the two fixed frames and opposite ends of the two side frames. Positioning extension plates are provided at both ends of the two fixed frames and both ends of the two side frames, extending from the positioning extension plates to corresponding fixed frames and two side frames. Support cylinders are provided at opposite ends of the two fixed frames at the top and bottom ends of the laminated glass. A support device is provided at one end of the support cylinder. Two columns are provided inside the support device, with one end of each column extending out of the support device. Flexible push blocks are provided at the extended ends of each column.

[0006] Preferably, each of the two columns inside the support is provided with an elliptical disk at its opposite end. The top of the elliptical disk is provided with a rotating shaft. The top of the rotating shaft extends through the support and the support frame into the interior of the fixed frame. The top of the rotating shaft is provided with a gear. The two gears on the same side are meshed with a push plate. When the push plate moves linearly inside the fixed frame, it will drive the corresponding two gears to rotate, causing the rotating shaft to rotate. The rotating shaft will drive the elliptical disk to rotate. When the elliptical disk rotates and the two long axis endpoints contact one end of the two columns respectively, the extended ends of the two columns will move towards both ends of the support, increasing the distance between the two flexible push blocks.

[0007] Preferably, an adjusting plate is provided between the two push plates inside the fixed frame. One end of the adjusting plate is provided with a reset component, and the other end of the adjusting plate is threadedly connected to the end of the fixed frame with a screw. The two rear ends of the adjusting plate are inclined surfaces. When the inclined end of the adjusting plate is located between the two push plates, the distance between the two push plates decreases. When the screw is screwed into the adjusting plate, the adjusting plate is pushed, so that the two front ends of the adjusting plate contact the two push plates respectively, causing the two push plates to move to the two sides of the fixed frame respectively, driving the two gears to rotate, causing the rotating shaft to drive the elliptical disk to rotate, and pushing the extension ends of the two columns to move towards the two ends of the support.

[0008] Preferably, the surface of the sun-protective glass is coated with a magnesium fluoride film, the surface of the laminated glass is coated with a cerium oxide film, and the surface of the dirt-resistant glass is coated with a fluoropolymer coating. The sun-protective glass is located on the outside of the sightseeing elevator door, and the dirt-resistant glass is located on the inside of the elevator door. The magnesium fluoride film can effectively reduce the reflection of the glass surface, thereby improving the light transmittance of the glass. The cerium oxide film can absorb ultraviolet rays and convert their energy into heat energy and dissipate it. While protecting against ultraviolet rays, it can also improve the weather resistance of the glass. The fluoropolymer coating has superhydrophobic and superoleophobic properties, making the glass surface less susceptible to water and oil contamination, and stains can easily slide off and be cleaned.

[0009] Preferably, the two sides of the fixing frame match the top and bottom of the side frame, respectively. The fixing frame and the side frame can be combined to form a square to protect the edges of the sun-proof glass, laminated glass and dirt-resistant glass.

[0010] Preferably, a return spring is connected between the flexible push block on the outer surface of the column and the support. When the two major axis endpoints of the elliptical disk move away from the two columns, the return spring will pull the flexible clamp block to move towards both ends of the support.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This anti-deformation elevator door uses a combination of sun-proof glass facing outwards and dirt-resistant glass and laminated glass facing inwards. The sun-proof glass and laminated glass absorb and diffuse ultraviolet rays, preventing direct ultraviolet rays from entering the elevator and causing skin damage to passengers inside the elevator. It also prevents the elevator door from deforming due to heat. The dirt-resistant glass has superhydrophobic and superoleophobic properties, making the glass surface less susceptible to water and oil stains. Stains easily slide off and are easy to clean.

[0013] 2. This anti-deformation elevator door uses a combination of side frames and a fixed frame. After the side frames and fixed frame fix the laminated glass, flexible push blocks that can extend and retract on both sides of the fixing device apply a pushing force to the sun-proof and dirt-resistant glass with the laminated glass as the center, fixing the glass. There is no need to drill holes in the glass surface to affect the rigidity of the glass, or to fix it with adhesive materials, which improves the stability of the glass fixing and makes it safer.

[0026] like Figures 1 to 9As shown, this embodiment of an anti-deformation elevator door includes a sun-protective glass 1, a laminated glass 4 at the rear end of the sun-protective glass 1, and a dirt-resistant glass 5 at the rear end of the laminated glass 4. The top and bottom ends of the sun-protective glass 1, the laminated glass 4, and the dirt-resistant glass 5 are all connected to a fixing frame 3. Side frames 2 are provided on both sides of the sun-protective glass 1, the laminated glass 4, and the dirt-resistant glass 5. The two fixing frames 3 and the two side frames 2 work together to fix the sun-protective glass 1, the laminated glass 4, and the dirt-resistant glass 5 in place. The sun-protective glass 1 is located in the direction facing outwards from the elevator door, and the dirt-resistant glass 5 is located in the direction facing inwards from the elevator door. Inwardly, the sun-protective glass 1 reduces surface reflection through a magnesium fluoride coating, thereby increasing light transmittance. The laminated glass 4 absorbs ultraviolet rays and converts their energy into heat through a cerium oxide coating, thus improving weather resistance while providing UV protection. The dirt-resistant glass 5 has a fluoropolymer coating that is superhydrophobic and superoleophobic, making it less susceptible to water and oil contamination, allowing stains to easily slide off and be cleaned. The opposite ends of the two fixed frames 3 and the opposite ends of the two side frames 2 are all equipped with elements corresponding to the laminated glass 4. Matching positioning frames 12, four positioning frames 12 fix the laminated glass 4 between the fixed frame 3 and the side frame 2. Positioning extension plates 13 are provided at both ends of the two fixed frames 3 and the two side frames 2. The positioning extension plates 13 position the dirt-resistant glass 5 and the sun-proof glass 1 located at both ends of the laminated glass 4. The positioning extension plates 13 extend to the corresponding two fixed frames 3 and two side frames 2. Support cylinders 11 are provided at the opposite ends of the two fixed frames 3 at the top and bottom ends of the laminated glass 4. A support 18 is provided at one end of the support cylinder 11. Two columns 1 are provided inside the support 18. 5. Supports 18 extend from one end of each of the two columns 15. Flexible push blocks 17 are provided at the extended ends of the two columns 15. After the dirt-resistant glass 5 and the sun-proof glass 1 located at both ends of the laminated glass 4 are installed, the supports 18 are located between the dirt-resistant glass 5 and the laminated glass 4, and between the sun-proof glass 1 and the laminated glass 4, respectively. The flexible push blocks 17 apply pushing force to the dirt-resistant glass 5 and the sun-proof glass 1, so that the edges of the dirt-resistant glass 5 and the sun-proof glass 1 are tightly attached to the corresponding positioning extension plates 13, ensuring that the sun-proof glass 1, the laminated glass 4 and the dirt-resistant glass 5 are stably combined into an elevator door.

[0027] Specifically, each of the two columns 15 inside the support 18 is provided with an elliptical disk 19 at its opposite end. The top of the elliptical disk 19 is provided with a rotating shaft 14. The top of the rotating shaft 14 extends through the support 18 and the support frame into the interior of the fixed frame 3. The top of the rotating shaft 14 is provided with a gear 10. The two gears 10 on the same side are meshed with a push plate 6. When the push plate 6 moves linearly inside the fixed frame 3, it will drive the corresponding two gears 10 to rotate, causing the rotating shaft 14 to rotate. The rotating shaft 14 will drive the elliptical disk 19 to rotate. When the elliptical disk 19 rotates and the two long axis ends contact one end of the two columns 15 respectively, the extended ends of the two columns 15 will move towards both ends of the support 18, increasing the distance between the two flexible push blocks 17.

[0028] Furthermore, an adjusting plate 9 is provided between the two push plates 6 inside the fixed frame 3. A reset component 8 is provided at one end of the adjusting plate 9, and a screw 7 is threadedly connected to the other end of the fixed frame 3. The two rear ends of the adjusting plate 9 are inclined surfaces. When the inclined end of the adjusting plate 9 is located between the two push plates 6, the distance between the two push plates 6 decreases. When the screw 7 is screwed into the adjusting plate 9, the adjusting plate 9 is pushed, so that the two front ends of the adjusting plate 9 contact the two push plates 6 respectively, so that the two push plates 6 move to the two sides of the fixed frame 3 respectively, pushing the two gears 10 to rotate, so that the rotating shaft 14 drives the elliptical disk 19 to rotate, pushing the extension ends of the two columns 15 to move towards the two ends of the support 18.

[0029] Furthermore, the surface of the sun-protective glass 1 is coated with magnesium fluoride, the surface of the laminated glass 4 is coated with cerium oxide, and the surface of the dirt-resistant glass 5 is coated with a fluoropolymer coating. The sun-protective glass 1 is located on the outside of the sightseeing elevator door, and the dirt-resistant glass 5 is located on the inside of the elevator door. The magnesium fluoride coating can effectively reduce the reflection of the glass surface, thereby improving the light transmittance of the glass. The cerium oxide coating can absorb ultraviolet rays and convert their energy into heat energy and dissipate it. While protecting against ultraviolet rays, it can also improve the weather resistance of the glass. The fluoropolymer coating has superhydrophobicity and superoleophobicity, making the glass surface less susceptible to water and oil contamination, and stains can easily slide off and be cleaned.

[0030] Furthermore, the two sides of the fixed frame 3 are matched with the top and bottom of the side frame 2 respectively. The fixed frame 3 and the side frame 2 can be combined into a square to protect the edges of the sun-proof glass 1, the laminated glass 4 and the dirt-resistant glass 5.

[0031] Furthermore, a return spring 16 is connected between the flexible push block 17 on the outer surface of the column 15 and the support 18. When the two major axis endpoints of the elliptical disk 19 move away from the two columns 15, the return spring 16 will pull the flexible clamping block to move towards both ends of the support 18.

[0032] The usage method of this embodiment is as follows: The anti-deformation elevator door is composed of sun-proof glass 1, laminated glass 4, and dirt-resistant glass 5. During assembly, the laminated glass 4 is first fixed between the fixed frame 3 and the side frame 2 by the matching positioning frame 12. Then, the dirt-resistant glass 5 and the sun-proof glass 1 are installed at both ends of the laminated glass 4. After the dirt-resistant glass 5 and the sun-proof glass 1 at both ends of the laminated glass 4 are installed, the support 18 is located between the dirt-resistant glass 5 and the laminated glass 4, and between the sun-proof glass 1 and the laminated glass 4, respectively. Then, the screw 7 is screwed into the adjusting plate 9. At this point, the adjusting plate 9 is pushed, causing the two front sides of the adjusting plate 9 to contact the two push plates 6 respectively, causing the two push plates 6 to move to the two sides of the fixed frame 3, pushing the two gears 10 to rotate, causing the rotating shaft 14 to drive the elliptical disk 19 to rotate, pushing the extension ends of the two columns 15 to move towards the two ends of the support 18, increasing the distance between the corresponding two flexible push blocks 17, applying pushing force to the dirt-resistant glass 5 and the sun-proof glass 1 respectively, so that the dirt-resistant glass 5 and the sun-proof glass 1 and the laminated glass 4 are fixed inside the side frame 2 and the fixed frame 3 by the pushing force, ensuring the stability of the glass.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
