Technical Field
[0001] The utility model relates to the technical field of elevator floor door anti-dropping, in particular to an elevator floor door anti-dropping structure. Background Art
[0002] The floor door is installed in the elevator hall and is used to control the connection between the elevator shaft and the elevator hall. In order to ensure the safe use of the elevator equipment, the floor door will only open together with the elevator door on the car when the elevator car arrives. The existing floor door anti-slip structure is still not perfect. After the floor door is impacted, the force position is concentrated in the middle and lower part of the floor door, resulting in large deformation of the middle and lower part of the floor door. People can easily fall into the elevator shaft through the deformed position of the middle and lower part of the floor door, posing a high safety hazard. Utility Model Content
[0003] The utility model aims to provide an elevator floor door anti-drop structure, aiming to solve the problems mentioned in the above background technology.

[0014] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.
[0015] like Figure 1-2 As shown, an elevator floor door anti-detachment structure includes a movable part installed on one side of a door panel 1 and a fixed part installed on one side of a door frame 2, the movable part includes a first connecting member 3, the first connecting member 3 is fixed to one side of the door panel 1, a hook plate 4 is arranged at one end of the first connecting member 3, the fixed part includes a second connecting member 5, the second connecting member 5 is fixed to one side of the door frame 2, a hanging plate 6 is arranged on one side of the second connecting member 5, and after the door panel 1 is closed, the hanging plate 6 is located inside the hook plate 4.
[0016] This type of elevator floor door anti-detachment structure is suitable for single-leaf doors and double-leaf doors. When used on single-leaf doors, it only needs to be installed on one side of the door panel 1. When used on double-leaf doors, it needs to be installed on both door panels 1. The moving part and the fixed part are both sheet metal parts, which are processed through a bending process. The first connecting member 3 and the hook plate 4 are bent from a whole piece of metal sheet. The first connecting member 3 is fixed to one side of the door panel 1 by welding and / or bolting. The second connecting member 5 and the hanging plate 6 are also bent from a whole piece of metal sheet. The second connecting member 5 is fixed to one side of the door frame 2 by welding and / or bolting.
[0017] When the door panel 1 is opened, the movable part moves with the door panel 1, and the distance between the movable part and the fixed part on the door frame 2 increases. When the door panel 1 is closed, the distance between the movable part and the fixed part on the door frame 2 is shortened, and at the same time, the scraper on the fixed part is located in the hook plate 4 in the movable part. When the door panel 1 is impacted, the door panel 1 is deformed, and at the same time, the distance between the door panel 1 and the door frame 2 increases. When the distance between the door panel 1 and the door frame 2 increases to a certain extent, the hook plate 4 abuts against the hanging plate 6, thereby preventing the door panel 1 from further deformation, that is, the hook plate 4 can prevent the door panel 1 from further moving away from the door frame 2, so as to improve the anti-slip ability of the door panel 1, and the first connecting member 3 in the movable part is arranged on the side of the door panel 1, which can improve the anti-deformation ability of the side of the door panel 1 and further improve the anti-slip ability of the layer door.
[0018] Furthermore, the first connecting member 3 at least covers the outer surface of the middle and lower part of one side of the door panel 1, and the hook plate 4, the second connecting member 5, and the hanging plate 6 are all equal to the length of the first connecting member 3. In the accident of the floor door falling off, most of the accidents are caused by people or objects hitting the middle and lower part of the door panel 1, causing the guide shoe at the lower end of the floor door to fall out of the sill. The main position of the floor door deformation is in the middle and below the door panel 1. By mainly covering the middle and below part of the door panel 1 with the first connecting member 3, the deformation resistance of the weak part of the door panel 1 can be improved, and the use of sheet metal materials can be reduced. At the same time, a complete moving part can be divided into multiple small moving parts, and the multiple small moving parts after division are evenly arranged in the middle and below the door panel 1, which can further save the use of sheet metal materials.
[0019] Furthermore, the length of the first connecting member 3 is equal to that of the hook plate 4, the length of the second connecting member 5 is equal to that of the hanging plate 6, the length of the first connecting member 3 is greater than that of the second connecting member 5, and covers 7 are respectively provided at both ends of the hook plate 4, and both ends of the hanging plate 6 are located between the two covers 7. When a person or object impacts the door panel 1 to a greater extent, the set covers 7 can improve the deformation resistance of the hook plate 4, thereby improving the abutment stability between the hook plate 4 and the hanging plate 6.
[0020] Furthermore, a reinforcing plate 8 is provided between the first connecting member 3 and the hook plate 4. The reinforcing plate 8 can prevent a large deformation between the first connecting member 3 and the hook plate 4, thereby further improving the anti-deformation capability of the moving part.
[0021] Furthermore, when the door panel 1 is in normal operation, the hanging plate 6 and the hook plate 4 do not contact each other. When the door panel 1 is normally opened and closed, the movable part and the fixed part do not contact each other, that is, the hook plate 4 and the hanging plate 6 do not contact each other, thereby preventing the hook plate 4 and the hanging plate 6 from generating noise due to friction.
[0022] The device can install a movable part and a fixed part on the sides of the door panel 1 and the door frame 2 respectively. When the door panel 1 is deformed, the hook plate 4 on the movable part and the scraper plate on the fixed part abut against each other, thereby preventing the door panel 1 from further deforming. In addition, the first connecting member 3 arranged on the door panel 1 can improve the deformation resistance of the side of the door panel 1 when the door panel 1 is subjected to external installation, thereby further enhancing the anti-slip ability of the layer door.
[0023] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
