Description

Anti-elevator door panel detached from the sill device

technical field

The utility model relates to the field of elevators, in particular to a device for preventing an elevator door panel from detaching from a sill.

Background technique

When the elevator in the floor is in the closed state, the lower end of the elevator door panel is located in the hall door sill installed on the floor surface, and there are door pockets fixedly connected with the wall on both sides of the hall door. In order to prevent the elevator door panel from breaking away from the sill anti-slip groove structure due to impact when the elevator door panel is in the closed state, but the existing anti-slip groove structure adopts horizontal horizontal limit, that is, the door panel is limited in the front and rear directions, but after According to the staff's pendulum test, when the middle part of the elevator door panel is impacted, the middle part of the elevator door panel will bend and deform in the direction of the force, which will cause the upper and lower ends of the elevator door panel to shrink toward the middle, thus causing the lower end of the elevator door panel to lift upward and break away from the floor It is easy to cause people to fall down the elevator shaft, which is a potential safety hazard.

Utility model content

The technical problem to be solved by the utility model is to provide a device for preventing elevator door panels from detaching from the sill with a vertical limit on the elevator door panels.

In order to solve the above-mentioned technical problems, the utility model is realized through the following technical solutions: a device for preventing elevator door panels from detaching from the sill, which includes elevator door panels, hall door sills located on the floor surface, and hall door sills located on both sides of the hall door and connected to the wall The door cover that is fixedly connected with the body, the elevator door panel and the door cover are provided with a limiting structure that cooperates with each other and prevents the elevator door panel from detaching from the hall door sill. The limiting part is fixedly connected to the second limiting part inside the door pocket. When the elevator door panel is in a closed state, the first limiting part is located directly below the second limiting part.

Preferably, the distance between the first limiting member and the second limiting member when the elevator door panels are in a closed state is 2 mm to 4 mm.

Preferably, the first limiting member includes a fixed end fixedly connected to the side of the elevator door panel and a limiting end extending toward the door pocket, the limiting end having a "C"-like structure.

Preferably, the first limiting member is located at the lower side of the elevator door panel.

With the above-mentioned structure, the utility model has the advantages that: the elevator door panel slides parallel to the door cover on the hall door sill, when the elevator door panel is closed, the two sides of the elevator door panel are flush with the inner surface of the door cover. The two sides of the elevator door panel and the inner side of the door cover are respectively provided with a first limiter and a second limiter. The second limiter is located directly above the first limiter, and since the door cover is fixed to the wall, the second limiter The second limiter is a fixed part, and when the elevator door panel receives momentum, the deformation of the middle part of the elevator door panel makes the lower part of the elevator door panel lift. The second limiter prevents the first limiter from being lifted up, thereby preventing the elevator door panel from detaching from the hall door sill and preventing people from falling into the elevator shaft. The structure is simple and ensures people's safety; the first limiter is set At the lower part of the side of the elevator door panel, according to the force in the middle of the elevator door panel, the deformation is the largest, so that the limiting effect is better, and the first limiting part is close to the sill, which further prevents the elevator door panel from detaching and makes the connection firm; the first The limit end of the limiter is a "C"-shaped structure placed horizontally. The opening of the limit end faces the side of the door pocket. The limit effect of the direction.

detailed description

Below in conjunction with accompanying drawing, the utility model is described further.

In the description of the present utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc. indicating the orientation or positional relationship are based on the positional relationship described in the accompanying drawings, and are only for the convenience of describing the present invention. Invention or simplification of description, rather than indicating a particular orientation that must be had.

As shown in Fig. 1 and Fig. 2, a device for preventing elevator door panels from detaching from the sill, which includes an elevator door panel 1, a hall door sill 2 located on the floor surface, and door pockets located on both sides of the hall door and fixedly connected to the wall 3. The elevator door panel 1 and the door cover 3 are provided with a limiting structure that cooperates with each other and prevents the elevator door panel 1 from detaching from the hall door sill 2. The limiting structure includes a first The limiting member 4 and the second limiting member 5 fixedly connected to the inner side of the door casing 3, when the elevator door panel 1 is in a closed state, the first limiting member 4 is located directly below the second limiting member 5.

The distance between the first limiting member 4 and the second limiting member 5 when the elevator door panel 1 is in a closed state is 2mm˜4mm.

The first limiting member 4 includes a fixed end 4.1 fixedly connected to the side of the elevator door panel 1 and a limiting end 4.2 extending toward the door casing 3, the limiting end 4.2 having a "C"-like structure.

The first limiting member 4 is located at the lower side of the elevator door panel 1 .

Figure 1 is the view from the elevator shaft to the elevator door panel, and Figure 2 is the view from the lobby to the elevator door panel. The elevator door panel 1 slides parallel to the door cover 3 on the hall door sill 2. When the elevator door panel 1 is closed, the elevator The two side surfaces of the door panel 1 are flush with the inner surface of the door cover 3, and the first limiter 4 and the second limiter 5 are respectively arranged on both sides of the elevator door panel 1 and the inner side of the door cover 3, and the second limiter 5 It is located directly above the first stopper 4, and because the door cover 3 is fixed to the wall, the second stopper 5 is a fixed part. When the elevator door panel 1 receives an impulse, the middle part of the elevator door panel 1 deforms so that the elevator door panel 1 The lower part is raised. The second limiting member 5 blocks the upward lifting of the first limiting member 4, thereby preventing the elevator door panel 1 from breaking away from the hall door sill 2 and preventing people from falling into the elevator shaft. The structure is simple and ensures the safety of people; The limiter 4 is located at the lower part of the side of the elevator door panel 1. According to the force in the middle of the elevator door panel, the deformation is the largest, so that the limit effect is better, and the first limiter is close to the sill, which further prevents the elevator door panel from detaching, making the connection Firm; the limiting end 4.2 of the first limiting member 4 is a "C"-shaped structure placed horizontally, and the opening of the limiting end 4.2 faces the side of the door pocket 3, and the upper and lower limit of the second limiting member 5 Simultaneously, it also has the effect of buckling the inner side of the door cover 3 and playing the position-limiting effect in the front-rear direction.

The utility model and its implementation have been described above. This description is not restrictive. What is shown in the drawings is only one implementation of the utility model, and the actual structure is not limited thereto. All in all, if a person of ordinary skill in the art is inspired by it, without departing from the purpose of the utility model, without creatively designing a structural method and embodiment similar to the technical solution, it shall be protected by the utility model scope.
