Technical Field

[0001] The utility model relates to the technical field of elevator landing doors, in particular to an anti - detachment structure for the door slider of a landing door panel. Background Technique

[0002] With the popularization of high - rise buildings, elevators, as vertical transportation tools, play an increasingly important role in modern life. The landing door is the door on the outside of the elevator on each floor and is an important part of the elevator. The door panel of the landing door is slidably arranged for opening and closing, and its safety is directly related to the personal safety of passengers.

[0003] In the prior art, the sliding structure of the landing door panel mostly includes a slideway and a slider arranged at the bottom of the door panel. The slider is inserted into the slideway, so that the door panel can slide open and close smoothly. The slider inserted into the slideway not only facilitates the sliding of the door panel but also limits the position of the door panel to a certain extent by the slider against the side wall of the slideway, so that the door panel will not fall off or topple.

[0004] However, in the actual use process, especially in some factories, when there are problems during the transportation of goods and the door panel is impacted, the sliding block is squeezed and turned out of the slideway, resulting in the door panel falling completely to the ground and causing injury to people and objects, which poses a certain safety risk. Content of the Utility Model

[0005] In order to reduce the safety risk, this application provides an anti - detachment structure for the door slider of a landing door panel.

[0006] The anti - detachment structure for the door slider of a landing door panel provided by this application adopts the following technical solutions:

[0007] An anti - detachment structure for the door slider of a landing door panel includes a door panel, a slideway block and a slider arranged on the door panel. The slideway block is provided with a sliding groove, the slider is inserted into the sliding groove and can slide in the sliding groove. The slider is provided with a fixing hook, the fixing hook is located in the sliding groove, and a fixing block is arranged on the inner wall of the sliding groove. The fixing hook can abut against the fixing block.

[0008] By adopting the above - mentioned technical solution, the slider is slidably arranged in the sliding groove of the slideway block. When the door panel is impacted, the slider is driven to tilt and squeeze the inner wall of the sliding groove. When the impact force is too large and the slider squeezes the inner wall of the sliding groove and is about to turn out of the sliding groove, the fixing hook will catch the fixing block and provide a supporting force, thereby limiting the slider and reducing the possibility of the slider completely turning out of the sliding groove, thus reducing the possibility of the door panel falling completely to the ground and causing injury to people or objects, and reducing the safety risk.

[0009] Preferably, the inner wall of the sliding groove abuts against the slider, the inner wall of the sliding groove is provided with a first fixing groove, and the fixing hook is inserted into the first fixing groove and can slide in the first fixing groove.

[0010] By adopting the above technical solution, the inner wall of the sliding groove abuts against the sliding block, which can improve the stability of the sliding block and the door panel during sliding, enhance the convenience of use. At the same time, by setting the first fixing groove, the fixing hook can be inserted into the first fixing groove and slide in the first fixing groove to avoid interference of the fixing hook with the movement of the sliding block. At the same time, the inner side wall of the first fixing groove can limit the fixing hook to a certain extent. When the sliding block presses against the inner wall of the sliding groove and has a tendency to come out, the fixing hook abuts against the inner wall of the first fixing groove to provide a supporting force, reducing the possibility of the sliding block coming out of the sliding groove and causing the door panel to fall, and reducing the safety risk.

[0011] Preferably, a second fixing groove is provided on the inner wall of the sliding groove. The second fixing groove is arranged above the first fixing groove and is not communicated with the first fixing groove. The fixing hook can be inserted into the second fixing groove, and the fixing block is arranged on the inner wall of the second fixing groove.

[0012] By adopting the above technical solution, by setting two first fixing grooves and second fixing grooves, double abutting insurance is provided for the fixing hook. When the fixing hook presses against the inner wall of the first fixing groove and the inner wall of the first fixing groove is deformed and comes out, the fixing hook will continue to rise and be inserted into the second fixing groove and abut against the fixing block on the inner wall of the second fixing groove, thereby further reducing the possibility of the sliding block coming out of the sliding groove and causing the door panel to fall, and reducing the safety risk.

[0013] Preferably, the sliding block is provided with a first assembly groove communicated with the sliding groove. The fixing hook can pass through the first assembly groove, and an assembly component is arranged between the fixing hook and the sliding block. The assembly component is used to assemble the fixing hook on the sliding block.

[0014] By adopting the above technical solution, during assembly, after inserting the sliding block into the sliding groove, the fixing hook is passed through the first assembly groove and inserted into the sliding groove, and the fixing hook is assembled on the sliding block through the assembly component. The operation is simple and convenient, enhancing the convenience of assembly and disassembly and replacement.

[0015] Preferably, the assembly component includes an assembly block and an assembly bolt. The fixing hook is arranged on the assembly block. The sliding block is provided with a second assembly groove. The assembly block can be inserted into the second assembly groove, and the assembly bolt is used to assemble the assembly block on the sliding block.

[0016] By adopting the above technical solution, during assembly, the assembly block is inserted into the second assembly groove on the sliding block, and the assembly block is assembled on the sliding block through the assembly bolt to complete the assembly. The operation is simple and convenient, enhancing the convenience of assembly and disassembly.

[0017] Preferably, it further includes a mounting block provided with a first mounting groove. The slide block is inserted into the first mounting groove and connected to the inner wall of the first mounting groove. The outer wall of the mounting block is provided with a second mounting groove that communicates with both the first mounting groove and the first assembly groove.

[0018] By adopting the above technical solution, the slide block is inserted into the first mounting groove of the mounting block, and the mounting block provides protection, which can reduce the possibility of damage caused by external impact on the slide block and the sliding block inside the slide block, and improve durability.

[0019] Preferably, a relief groove is provided on the outer wall of the slide block, and the relief groove is provided between the first fixing groove and the second fixing groove.

[0020] By adopting the above technical solution, by providing a relief groove, when the sliding block presses against the inner wall of the sliding groove, the slide block can undergo appropriate deformation at the relief groove to offset the pressing force of the sliding block, thereby reducing the possibility that the sliding block continuously presses and finally flips out of the sliding groove, causing the door panel to fall off and tip over, and further reducing the safety risk.

[0021] Preferably, the sliding block is provided with a connecting plate, and the door panel is provided with a connecting bolt for mounting the connecting plate on the door panel.

[0022] By adopting the above technical solution, the sliding block is mounted on the door panel through the connecting plate and the connecting bolt, which facilitates the disassembly and replacement of the sliding block when the sliding block is damaged.
