Description
Technical Field
[0001] The utility model relates to the technical field of elevator landing doors, in particular to a device for preventing the landing door panel from falling off. Background Art
[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 outside 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 insertion of the slider 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, the landing door is often impacted. Especially in scenarios such as factories where transportation is required, after being impacted, the landing door drives the sliding and tilting movement, causing the slider to squeeze and impact the inner wall of the slideway, resulting in the opening of the slideway expanding and deforming. After the opening of the slideway expands, the risk of the slider detaching from the slideway is higher. When the door panel is impacted again during subsequent use, it is easy to occur that the slider topples and detaches from the slideway, leading to the possibility of the landing door panel toppling and falling off, posing a certain safety risk. Summary of the Utility Model
[0005] In order to reduce the safety risk, the present application provides a device for preventing the landing door panel from falling off.
[0006] The device for preventing the landing door panel from falling off provided by the present application adopts the following technical solutions:
[0007] A device for preventing the landing door panel from falling off includes a door panel, a slideway block, a mounting block, and a sliding block arranged on the door panel. The slideway block is provided with a sliding groove, the sliding block is inserted into the sliding groove and can slide in the sliding groove. The mounting block is provided with a mounting groove, the slideway block is inserted into the mounting groove, and a first abutting block is arranged on the inner wall of the mounting groove, and the first abutting block abuts against the slideway block.
[0008] By adopting the above technical solutions, the sliding block is inserted into the sliding groove of the slideway block. When the door panel is impacted and drives the sliding block to tilt and squeeze the inner wall of the sliding groove, the first abutting block on the inner wall of the mounting groove abuts against the side wall of the slideway block to provide a supporting force, reducing the possibility of the slideway block being squeezed and expanded and deformed, thereby reducing the possibility that the slider detaches from the sliding groove when the door panel is impacted, and reducing the safety risk.
[0009] Preferably, the slide block is provided with a mounting plate which covers the first abutting block.
[0010] By adopting the above technical solution, since the mounting plate covers the first abutting plate, the possibility of the first abutting plate being damaged by collision and bending is reduced, thereby reducing the probability of deformation of the first abutting plate, ensuring the abutting protection of the slide block, reducing the possibility of the slide block deforming and causing the sliding groove to deform, and reducing the safety risk of the door panel falling off due to the sliding block disengaging from the sliding groove.
[0011] Preferably, the mounting plate is provided with a second abutting block which is inserted into the mounting groove and abuts against the first abutting block.
[0012] By adopting the above technical solution, by providing the second abutting block which abuts against the first abutting block, the slide block is subjected to abutting force, reducing the possibility of the slide block being extruded and deformed. At the same time, by providing the second abutting block, the length of the first abutting block is reduced, reducing the possibility of the first abutting block being deformed by force when the slide block is extruded, thereby improving the durability while making the overall structure of the abutting slide block more stable, and reducing the possibility of the sliding block being extruded and deformed during long-term use.
[0013] Preferably, the slide block is provided with a fixing plate which is provided with fixing bolts for mounting the fixing plate on the mounting block.
[0014] By adopting the above technical solution, the fixing plate is mounted on the mounting block through the fixing bolts, thereby fixing the slide block on the mounting block to complete the installation, and the operation is simple and convenient.
[0015] Preferably, the fixing plate is provided with fixing nuts threadedly connected to the fixing bolts. The fixing bolts penetrate through the fixing plate and the mounting block, and the fixing plate is inserted into the mounting groove. The fixing bolts and the fixing nuts are used to mount the fixing plate on the inner wall of the mounting groove.
[0016] By adopting the above technical solution, the fixing plate is arranged in the mounting groove. The fixing bolts sequentially pass through the fixing plate and the mounting block inside the mounting groove, and the fixing nuts are sleeved on the fixing bolts outside the mounting groove and tightened, thereby mounting the mounting plate on the inner wall of the mounting groove and the fixing plate in the mounting groove, reducing the possibility of the fixing plate being damaged by collision and improving the durability.
[0017] Preferably, the inner wall of the sliding groove is provided with limiting blocks which abut against the sliding block.
[0018] By adopting the above technical solution, the limiting block abuts against the sliding block, thereby sharing part of the extrusion force received by the slideway block when the door panel is collided and drives the sliding block to tilt, reducing the possibility of the inner wall of the sliding groove being extruded and deformed, improving durability, also increasing the possibility of the door panel falling off, and reducing safety risks.
[0019] Preferably, the limiting block is provided with a first relief groove, and the inner wall of the sliding groove is provided with a second relief groove communicated with the first relief groove.
[0020] By adopting the above technical solution, by providing the first relief groove and the second relief groove, enough deformation space is left for the limiting block. The limiting block is deformed under pressure to share the extrusion force received by the inner wall of the sliding groove, thereby reducing the possibility of the inner wall of the sliding groove being deformed after being extruded, reducing the risk of the door panel falling off, and improving safety performance.
[0021] Preferably, the sliding block is provided with an assembly plate, and the door panel is provided with an assembly bolt and an assembly nut connected by threads. The assembly bolt and the assembly nut are used to assemble the assembly plate and the door panel together.
[0022] By adopting the above technical solution, the assembly plate is assembled on the door panel through the assembly bolt and the assembly nut, thereby assembling the door panel and the sliding block together. When the door panel or the sliding block is damaged, it can be disassembled and replaced.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. By providing a door panel, a sliding block, a slideway block, a mounting block, a sliding groove, a mounting groove and a first abutting block, the sliding block on the door panel is inserted into the sliding groove of the slideway block, the slideway block is inserted into the mounting groove of the mounting block, and the side wall of the slideway block is abutted by the first abutting block on the inner wall of the mounting groove, thereby bearing the extrusion force received by the slideway block when the door panel is impacted and drives the sliding block to extrude the inner wall of the sliding groove, reducing the possibility of the slideway block being deformed under pressure, thereby reducing the probability of the door panel falling off and reducing safety risks;
[0025] 2. By providing a mounting plate and a second abutting block, the slideway block is provided with a mounting plate covering the first abutting plate, thereby cooperating with the first abutting plate to shield the mounting groove. At the same time, the second abutting block abuts against the first abutting block, thereby sharing the pressure received by the first abutting block when being extruded, the length of the first abutting block can be shortened, thereby reducing the possibility of the first abutting block being bent and deformed under pressure, improving durability while reducing the possibility of the slideway block being deformed, thereby reducing the probability of the door panel falling off and reducing safety risks;
[0026] 3. By setting a fixing plate, fixing bolts and fixing nuts, the fixing plate is installed on the inner wall of the mounting groove through the fixing bolts and fixing nuts, so that the slide block is installed in the mounting groove. The operation is simple and convenient. At the same time, the fixing plate is located in the mounting groove, which reduces the possibility of damage caused by collision and improves durability.

[0030] The following is combined with Figure 1-2 This application is described in further detail.
[0031] The embodiment of the present application discloses a device for preventing a door panel 1 from falling off. Figures 1 to 2 , which comprises a door panel 1, a slide block 3, a mounting block 4 and a plurality of sliding blocks 2 arranged on the door panel 1, wherein the slide block 3 is provided with a sliding groove 31 along the length direction, and the sliding block 2 is slidably inserted into the sliding groove 31. The mounting block 4 is provided with a mounting groove 41 along the length direction, and the slide block 3 is inserted into the mounting groove 41, and the inner walls on both sides of the mounting groove 41 are integrally fixedly provided with a first abutting block 42. Both sides of the top wall of the slide block 3 are integrally fixedly provided with a mounting plate 33, and the bottom wall of the mounting plate 33 is covered on the top wall of the first abutting block 42, and the top wall of the mounting plate 33 abuts against the bottom wall of the door panel 1. In another embodiment, the mounting plate 33 does not abut against the door panel 1, but the sliding block 2 abuts against the bottom wall of the sliding groove 31 to achieve support. The bottom wall of the mounting plate 33 is integrally fixedly provided with a second abutting block 331, and the second abutting block 331 abuts against the side wall of the first abutting block 42 away from the inner wall of the mounting groove 41. The slide block 3 can be formed by bending a steel plate into a slide groove 31, a mounting plate 33 and a second abutment block 331. The first abutment block 42 abuts against the second abutment block 331, thereby limiting the slide block 3. By abutting and sharing the pressure, the possibility of the inner wall of the slide groove 31 being deformed and expanded due to the extrusion of the slide block 2 is reduced, thereby reducing the possibility of the slide block 2 being separated from the slide groove 31 and causing the door panel 1 to tilt and fall off, thereby reducing the safety risk.
[0032] To further reduce the safety risk, referring to Figure 1 and Figure 2 , a limiting block 32 is integrally and fixedly arranged on one inner wall of the sliding groove 31. The length direction of the limiting block 32 is consistent with the length direction of the sliding groove 31, and the top wall and the bottom wall of the limiting block 32 are inclined. The side of the limiting block 32 away from the inner wall of the sliding groove 31 abuts against the sliding block 2. A first relief groove 321 is arranged along the length direction on the side of the limiting block 32 away from the sliding block 2, and a second relief groove 311 communicating with the first relief groove 321 is arranged through the inner wall of the sliding groove 31. The slideway block 3 can be formed by bending a steel plate to form the limiting block 32, the first relief groove 321 and the second relief groove 311. In another embodiment, in order to reduce the possibility of the door panel 1 tilting and falling off to both sides, the limiting block 32 and the second relief groove 311 are arranged on the inner walls on both sides of the sliding groove 31. The limiting block 32 is arranged on the inner wall of the sliding groove 31 on the side opposite to the side where the door panel 1 is often impacted. When the door panel 1 is impacted and drives the sliding block 2 to squeeze the inner wall of the sliding groove 31, the sliding block 2 squeezes the limiting block 32, the limiting block 32 is deformed by the force, and the first relief groove 321 and the second relief groove 311 are displaced to relieve the extrusion force, thereby reducing the possibility of the inner wall of the sliding groove 31 being deformed, and further reducing the possibility of the sliding block 2 disengaging from the sliding groove 31 and causing the door panel 1 to tilt and fall off, and further reducing the safety risk. In another embodiment, a hook can be arranged on the sliding block 2 and a clamping block can be arranged on the inner wall of the sliding groove 31. When the sliding block 2 is about to disengage from the sliding groove 31, the hook hooks the clamping block, so that the sliding block 2 cannot disengage from the sliding groove 31 to reduce the possibility of the door panel 1 toppling and falling off.
[0033] For the convenience of assembly, referring to Figure 1 and Figure 2, a fixed plate 34 is fixedly arranged on the bottom wall of the slide block 3. The fixed plate 34 abuts against the bottom wall of the installation groove 41. The fixed plate 34 is provided with a fixing bolt 341 and a fixing nut 342 connected by threads. The fixing bolt 341 passes through the fixed plate 34 and the installation block 4. The fixing bolt 341 and the fixing nut 342 are used to install the fixed plate 34 on the inner wall of the installation groove 41. The door panel 1 is provided with a first assembly groove 11 and a second assembly groove 12. An assembly plate 21 is fixedly arranged on the top wall of the sliding block 2. The assembly plate 21 is inserted into the first assembly groove 11. The assembly plate 21 is provided with an assembly bolt 22 and an assembly nut 23 connected by threads. The assembly bolt 22 is located in the second assembly groove 12, and the assembly nut 23 is located in the first assembly groove 11. The assembly bolt 22 and the assembly nut 23 are used to assemble the assembly plate 21 and the door panel 1 together. The installation block 4 is provided with a plurality of bolts for assembling the installation block 4 between the landing sill. When assembling the assembly plate 21 and the door panel 1, it is necessary to insert the hand into the first assembly groove 11 and the second assembly groove 12, or the assembly bolt 22 can be welded to the inner wall of the second assembly groove 12. When assembling the slide block 3 and the installation block 4, after passing the fixing bolt 341 through the fixed plate 34, insert the slide block 3 into the installation groove 41, and make the fixing bolt 341 pass through the installation block 4. Assembly is carried out through bolts and nuts, with simple and convenient operation, facilitating disassembly and replacement of parts.
[0034] The implementation principle of a device for preventing the door panel 1 of a landing door from falling off according to an embodiment of the present application is as follows: The second abutting block 331 is arranged on the mounting plate 33 integrally connected to the top wall of the slide block 3 and abuts against the first abutting block 42 on the inner wall of the installation groove 41. Thus, the top of the slide block 3 is abutted by the first abutting block 42. When the door panel 1 is impacted and drives the sliding block 2 to tilt and squeeze the inner wall of the sliding groove 31, the first abutting block 42 bears the extrusion pressure through the second abutting block 331 and the mounting plate 33, thereby reducing the possibility of the slide block 3, especially the top of the slide block 3, expanding and deforming, and further reducing the possibility that the door panel 1 is impacted again, causing the sliding block 2 to disengage from the sliding groove 31 and the door panel 1 to fall off, reducing the safety risk.
[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
