One is the hall door on each floor in the corridor, and the other is the car door used for closed elevators. Generally, the car door is installed on the elevator car through the door machine and the door frame, and the car door needs to be moved. Therefore, when it is connected to the driving component of the door machine through the connecting piece, a certain gap will be left between the car door and the inner wall of the door frame.

[0003] In the prior art, some high-rise buildings have many floors, so it is necessary to increase the moving speed of the elevator. When the moving speed of the elevator increases, it will cause the airflow to easily enter from the gap between the car door and the door frame. Although it cannot enter the car, the airflow will cause the noise of airflow impact when it flows rapidly in the gap, thereby reducing the comfort during use. Generally, when sealing, sealing strips are mainly installed on the side walls of the car door and the inner wall of the door frame to achieve the sealing effect. However, after long-term use, the sealing strips will be damaged due to mutual friction, thereby reducing the sealing performance. Utility Model Content

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1-Figure 4 The utility model discloses an elevator car door with a sealing structure, comprising a door frame 1, a car door panel 2, a plurality of guide shoes 3 and two guide rails 4, wherein the plurality of guide shoes 3 are respectively fixedly mounted on the top side and the bottom side of the car door panel 2, and the two guide rails 4 are respectively fixedly mounted on the top side wall and the bottom side wall of the door frame 1, and the guide rails 4 are slidably connected with the corresponding guide shoes 3, and the top side and the bottom side of the car door panel 2 are both provided with sealing members 5;

[0026] The sealing member 5 includes a plurality of static sealing blocks 6, and a plurality of the static sealing blocks 6 are fixedly connected to the end side walls in the door frame 1. The lengths of the plurality of static sealing blocks 6 are different, and the plurality of static sealing blocks 6 are distributed in a linear array and arranged in a stepped manner. A plurality of dynamic sealing blocks 7 are fixedly connected to the end of the car door panel 2, and the ends of each dynamic sealing block 7 are respectively in contact with the corresponding static sealing block 6. Two side sealing strips 8 are fixedly connected to the inner side wall of the door frame 1, and the static sealing block 6 is located between the two side sealing strips 8, and the side of the side sealing strip 8 close to the car door panel 2 is arranged in a stepped manner. The end side of the car door panel 2 is fixedly connected with a side sealing strip 2 9, and the dynamic sealing block 7 is located between the two side sealing strips 2 9, and the side of the side sealing strip 2 9 away from the car door panel 2 is arranged in a stepped manner, and the side sealing strip 1 8 and the side sealing strip 2 9 are engaged with each other.

[0027] In this embodiment, when the elevator is in use, the door machine will drive the car door panel 2 to slide on the guide rail 4 through the guide shoe 3, and then the car door panel 2 will be closed. When the car door panel 2 moves, it will drive the dynamic sealing block 7 and the side sealing strip 2 9 to move, and several dynamic sealing blocks 7 will gradually fit with the corresponding static sealing blocks 6. At the same time, the side of the side sealing strip 2 9 away from the car door panel 2 will gradually fit with the side of the side sealing strip 1 8 that is arranged in a stepped manner, so that the dynamic sealing block 7 and the static sealing block 6 fit and seal, and the side sealing strip 2 9 and the side sealing strip 1 8 fit and seal. Finally, when the car door panel 2 is closed and sealed, the friction between the dynamic sealing block 7 and the static sealing block 6 and the friction between the side sealing strip 1 8 and the side sealing strip 2 9 are avoided, so that when the car door panel 2 is closed and sealed, it can avoid the friction between the side sealing strip 1 8 and the side sealing strip 2 9 due to frequent friction without affecting the sealing, thereby improving the practicality.

[0028] When the dynamic sealing block 7 and the static sealing block 6 are in close contact and sealed, it can prevent the airflow from passing through the side sealing strip 1 8 and the side sealing strip 2 9 when the elevator moves up and down, thereby causing the flow of air to cause noise. The side sealing strip 1 8 and the side sealing strip 2 9 are set to prevent the airflow from entering from the outside of the elevator door through the gap between the car door panel 2 and the door frame 1, thereby causing the airflow to enter the elevator car, thereby generating noise, and prevent the airflow from entering the car, reducing the user experience.

[0029] In a further preferred embodiment of the present invention, Figure 4 As shown, a cushion 10 is fixedly connected to the end of the dynamic sealing block 7 , and an escape groove 11 for evading the cushion 10 is provided at the end of the static sealing block 6 .

[0030] In this embodiment, the soft pad 10 is used to allow the soft pad 10 to be embedded in the avoidance groove 11 on the static sealing block 6 when the dynamic sealing block 7 moves with the car door, and then the dynamic sealing block 7 and the static sealing block 6 are squeezed after being fitted together, thereby improving the sealing performance of the dynamic sealing block 7 and the static sealing block 6.

[0031] In a further preferred embodiment of the present invention, Figure 4 As shown, the dynamic sealing block 7 and the static sealing block 6 are both composed of an inner core block 12 and a sealing sleeve 13 , and the inner core block 12 is fixedly installed in the sealing sleeve 13 .

[0032] In this embodiment, the inner block is made of steel or iron to improve the strength of the dynamic sealing block 7 and the static sealing block 6, and avoid the extrusion of the dynamic sealing block 7 and the static sealing block 6 causing the dynamic sealing block 7 and the static sealing block 6 to deform, thereby affecting the sealing effect. The sealing sleeve 13 is made of rubber or silicone, and the dynamic sealing block 7 and the static sealing block 6 are pressed together to achieve a sealing effect.

[0033] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the side walls of the car door panel 2 are fixedly connected with longitudinal sealing pads 14 , and the side walls inside the door frame 1 are fixedly connected with snap-fitting rubber pads 15 .

[0034] In this embodiment, the longitudinal sealing gasket 14 is arranged to fit together when the two car door panels 2 are close to each other, so that the car door panels 2 can achieve a sealing effect after closing, and prevent air flow from entering from between the two car panels when the elevator rises or descends. The arranged locking rubber gasket 15 is used to serve as a buffer for the car door panels 2, the dynamic sealing block 7 and the side sealing strip 9 when the car door panels 2 are opened, so as to prevent multiple collisions caused by the door jams from causing damage to the car door panels 2, the dynamic sealing block 7 and the side sealing strip 9.

[0035] In a further preferred embodiment of the present invention, Figure 2-3As shown, a groove 16 is formed on the side of the longitudinal sealing pad 14 away from the car door panel 2 , and an airbag cushion 18 is fixedly connected to the side wall of the groove 16 , and the side of the airbag cushion 18 extends to the opening of the groove 16 .

[0036] In this embodiment, the groove 16 provided on the longitudinal sealing pad 14 is used to fix the airbag cushion 18. When the two car door panels 2 are closed, the longitudinal sealing pads 14 are close to each other and will squeeze the airbag cushion 18, thereby causing the airbag cushion 18 to deform. After the airbag cushion 18 is deformed, it will block the position where the two longitudinal sealing pads 14 are in contact, further improving the sealing performance of the car door panels 2 when they are in contact.

[0037] In a further preferred embodiment of the present invention, Figure 1 As shown, a buffer convex strip 17 is fixedly connected to one side of the snap-fitting rubber pad 15 close to the car door panel 2 .

[0038] In this embodiment, the buffer ridges 17 are used to further buffer the car door panel 2, so that the car door panel 2 is doubly buffered by the buffer ridges 17 and the snap-fitting rubber pads 15, thereby improving the stability of the car door when it is opened and avoiding vibration that affects the use of the elevator.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
