Description

Technical Field

[0001] This utility model belongs to the field of subway platform screen door technology, and relates to a subway platform screen door threshold module, and more particularly to a subway platform screen door threshold module and a subway platform screen door threshold using the same. Background Technology

[0002] The threshold assembly of a subway platform screen door system typically consists of two parts: a front threshold and a rear threshold. The front and rear thresholds are arranged in parallel along the track direction at a preset distance, and the preset distance between the front and rear thresholds forms the guide groove for the installation and operation of the door.

[0003] Currently, according to engineering specifications, a protective outer panel that combines decorative and protective wear-resistant functions needs to be installed on the outer sill (rear sill). Traditional implementation methods often use a carbon steel substrate, bent and welded with reinforcing ribs, followed by surface coating, and then assembled and fixed to the aluminum profile of the outer sill using self-tapping screws. This traditional technical solution has the following significant drawbacks: 1. Material properties: Carbon steel components have a high density, resulting in excessive overall structural weight; 2. Process complexity: Multiple welding processes and surface coating treatments are required, making the process lengthy; 3. Dimensional accuracy control: Welding thermal deformation easily leads to the accumulation of component shape and position tolerances, affecting assembly accuracy; 4. Maintenance feasibility: The composite structure is inconvenient to disassemble and maintain, and there is a risk of electrochemical corrosion. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a subway platform screen door threshold module and a subway platform screen door threshold using the same. It solves the technical problem of difficult construction and installation of existing external thresholds.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A subway platform screen door threshold module includes an aluminum alloy threshold body and a decorative outer panel. The aluminum alloy threshold body has a block-shaped structure and its top has two sliding grooves arranged at intervals along its length. The sliding grooves extend along the width of the aluminum alloy threshold body to the side to form an opening. The sliding groove has a first groove wall and a second groove wall, and the sliding groove has a third groove wall and a fourth groove wall. The first groove wall, the fourth groove wall and / or the second groove wall and the third groove wall are all provided with mutually symmetrical locking grooves. The decorative outer panel has two protruding ribs that cooperate with the sliding grooves. The sides of the two protruding ribs have locking parts that protrude along their length. The locking parts can slide along the length of the locking groove, and the protruding ribs and the upper and lower sides of the locking groove form abutments to prevent the decorative outer panel from falling out.

[0007] This application modularizes the threshold of subway platform screen doors, which greatly improves installation efficiency. Each module includes an aluminum alloy threshold body and a decorative outer panel. The aluminum alloy threshold body is embedded below the ground, and the decorative outer panel is snapped onto the top of the aluminum alloy threshold body, flush with the ground. The decorative outer panel and the aluminum alloy threshold body are interlocked, making the installation method very convenient and efficient, and also very easy to disassemble and replace in case of subsequent damage.

[0008] The aluminum alloy door sill body has two grooves, and the decorative outer panel has raised ribs that cooperate with the grooves. Both grooves extend laterally to the side of the aluminum alloy door sill body to form an opening. Therefore, the raised ribs can slide directly into the opening from the side. The snap-fit ​​part on the raised rib can engage with the snap-fit ​​groove on the grooves. During installation, it can be directly slid into the snap-fit ​​groove through the opening to complete the snap-fit. The snap-fit ​​can limit the vertical movement of the decorative outer panel, while it can still slide along the snap-fit ​​groove in the front-back direction. This design makes installation very convenient.

[0009] The card slots of this application are respectively opened on the opposite sides of the slide groove one and slide groove two, so that the card slot one and card slot two can be opposite to each other in the width direction of the aluminum alloy door sill body to restrict the two card-connecting parts. The two card-connecting parts face each other and interact with the card slot to limit the movement. This can effectively prevent any card-connecting part from disengaging from the card slot due to the fit gap. The connection strength and connection stability are excellent.

[0010] In the aforementioned subway platform screen door threshold module, the first groove wall, the second groove wall, the third groove wall, and the fourth groove wall are all vertically arranged.

[0011] In this application, several sections of the walls of slide groove one and slide groove two are vertically arranged, which makes installation and alignment convenient.

[0012] In the aforementioned subway platform screen door threshold module, the snap-fit ​​part has a continuous protruding structure and is distributed on the side of the protruding rib along the length direction of the rib.

[0013] The snap-fit ​​part of this application has a continuous protruding structure. Such a snap-fit ​​part has a large contact area and high structural strength when it is engaged with the slot. Moreover, the snap-fit ​​part and the slot are engaged and limited in the vertical direction, which makes the decorative outer panel fit more closely with the aluminum alloy door frame body and the installation effect better.

[0014] In the aforementioned subway platform screen door threshold module, the decorative outer panel is an FRP board, the outline of the decorative outer panel is the same as the outline of the aluminum alloy threshold body, and all outer surfaces of the decorative outer panel are flush with the outer surfaces of the aluminum alloy threshold body.

[0015] The decorative outer panel in this application uses FRP (fiberglass reinforced plastic) board, which has high structural strength, wear resistance, slip resistance, and long service life. Furthermore, after installation, the entire decorative outer panel is flush with the outer surface of the aluminum alloy door sill. When multiple modules are installed, adjacent decorative outer panels are installed without gaps, abutting against each other. The decorative outer panels are inserted into the width of the aluminum alloy door sill body and then mutually restrained and limited along their length to form a unified whole. This installation method is simple and convenient.

[0016] In the aforementioned subway platform screen door threshold module, the bottom of both the first and second slide grooves are flush with the lower side wall of the corresponding card slot.

[0017] The slots distributed on slide 1 and slide 2 are all in contact with the bottom of slide 1 and slide 2, which makes it easy for the protruding rib to slide in while the locking part is aligned and locked into the slot, making installation convenient.

[0018] In the aforementioned subway platform screen door threshold module, the gap between the decorative outer panel and the aluminum alloy threshold body is less than 1mm.

[0019] In the aforementioned subway platform screen door threshold module, there is a movable gap between the sidewalls of the first and second slide grooves and the side of the rib.

[0020] The protruding rib of this application has a movable gap in the lateral direction with the first and second slides. Such a movable gap will not affect the movement of a single decorative panel, because adjacent decorative panels abut against each other. The design of the movable gap allows for a certain amount of space to smoothly insert the decorative panel during installation. At the same time, during use, the movable gap allows the entire decorative panel to move slightly in the assembly direction of the width, which can meet the needs of thermal expansion and contraction or movement under special circumstances.

[0021] In the aforementioned subway platform screen door threshold module, the aluminum alloy threshold body has at least two hollow cavities.

[0022] The design with multiple hollow cavities allows the aluminum alloy door sill to minimize material usage while maintaining its structural strength, effectively saving material costs.

[0023] In the aforementioned subway platform screen door threshold module, a groove is provided at the bottom of the aluminum alloy threshold body in the middle area, and a support part protrudes from the groove opening.

[0024] The aluminum alloy door sill body of this application has a groove at the bottom. The groove can reduce the material and meet the installation clearance requirements, so that the support can be better buried in the ground and the ground fixation strength is better.

[0025] A subway platform screen door threshold includes several of the aforementioned subway platform screen door threshold modules. The feature is that the aluminum alloy threshold bodies on two adjacent subway platform screen door threshold modules abut against each other in the length direction, and when the decorative outer panel is engaged with the aluminum alloy threshold body, the adjacent decorative outer panels abut against each other in the length direction.

[0026] The overall screen door threshold is formed by horizontally assembling the aforementioned threshold modules. Adjacent aluminum alloy threshold bodies abut against each other, and decorative outer panels can be inserted and snapped into place in the width direction. In the length direction, the decorative outer panels abut against each other to limit movement. This design greatly reduces installation steps, reduces costs and increases efficiency, and is very convenient to install.

[0027] The beneficial effects of this utility model are as follows: This application modularizes the threshold of subway platform screen doors, which greatly improves installation efficiency through modular construction. Each module includes an aluminum alloy threshold body and a decorative outer panel. The aluminum alloy threshold body is embedded below the ground, and the decorative outer panel is snapped onto the upper end of the aluminum alloy threshold body, flush with the ground. The decorative outer panel and the aluminum alloy threshold body are interlocked, making the installation method very convenient and efficient, and also very easy to disassemble and replace in case of subsequent damage.

[0030] like Figure 1The subway platform screen door threshold module shown includes an aluminum alloy threshold body 1 and a decorative outer panel 2. The aluminum alloy threshold body 1 has a block-shaped structure and its top has two grooves 11 and 12 arranged at intervals along the length direction. The grooves 11 and 12 extend to the side along the width direction of the aluminum alloy threshold body 1 to form an opening. The groove 11 has a first groove wall 111 and a second groove wall 112, and the groove 12 has a third groove wall 121 and a fourth groove wall 122. Symmetrical slots 13 are provided on the first slot wall 111, the fourth slot wall 122, and / or the second slot wall 112 and the third slot wall 121. Two protruding ribs 21 protrude from the decorative outer panel 2, engaging with the first and second slots 11 and 12. Engaging portions 22 protrude along the length of the sides of the two ribs 21, allowing them to slide along the length of the slot 13. The ribs 21 and the upper and lower sides of the slot 13 act as abutments to prevent the decorative outer panel 2 from falling out. The ribs 21 and the engaging portions 22 are integrally formed into an L-shaped hook structure. This application modularizes the threshold of the subway platform screen door, greatly improving installation efficiency through modular construction. Each module includes an aluminum alloy door sill body 1 and a decorative outer panel 2. The aluminum alloy door sill body 1 is embedded below the ground, and the decorative outer panel 2 is snapped onto the upper end of the aluminum alloy door sill body 1 and flush with the ground. The decorative outer panel 2 and the aluminum alloy door sill body 1 are interlocked. This installation method is very convenient and efficient, and it is also very easy to disassemble and assemble, making it easy to replace in case of subsequent damage. The aluminum alloy door sill body 1 has a sliding groove 11 and a sliding groove 22. The decorative outer panel 2 has a raised rib 21 that cooperates with the sliding groove 11 and the sliding groove 22. The sliding groove 11 and the sliding groove 22 extend laterally to the side of the aluminum alloy door sill body 1 to form an opening. Therefore, the raised rib 21 can slide directly into the opening from the side. The snap-fit ​​part 22 on the raised rib 21 can snap into the snap-fit ​​groove 13 on the sliding groove 11 and the sliding groove 22. During installation, it can also be directly slid into the snap-fit ​​groove 13 through the opening to complete the snap-fit. The snap-fit ​​can limit the vertical movement of the decorative outer panel 2, and it can still slide along the snap-fit ​​groove 13 in the front-back direction. This design makes the installation and construction very convenient. The slots 13 of this application are respectively formed on the opposite sides of the sliding groove 11 and the sliding groove 12, so that the slots 131 and 132 can be oriented relative to each other in the width direction of the aluminum alloy sill body 1 to restrict the two locking parts 22. The two locking parts 22 face each other, and the two locking parts 22 interact with the slots 13 to limit the engagement, effectively preventing any locking part 22 from disengaging from the slot 13 due to a gap in the fit. The connection strength and stability are excellent. Preferably, the first groove wall 111, the second groove wall 112, the third groove wall 121, and the fourth groove wall 122 are all vertically arranged. The vertical arrangement of the groove walls of the sliding groove 11 and the sliding groove 12 facilitates installation and alignment. Preferably, the locking parts 22 have a continuous protruding structure and are distributed along the length direction of the rib 21 on the side of the rib 21.The snap-fit ​​part 22 of this application has a continuous protruding structure. When such a snap-fit ​​part 22 is engaged with the slot 13, the contact area is large and the structural strength is high. Moreover, with the snap-fit ​​part 22 and the slot 13 abutting and limiting in the vertical direction, the decorative outer panel 2 and the aluminum alloy door frame body can fit together more closely and the installation effect is better.

[0031] Furthermore, the decorative outer panel 2 is made of FRP (fiberglass reinforced plastic) board. The outline of the decorative outer panel 2 is the same as that of the aluminum alloy threshold body 1, and all outer surfaces of the decorative outer panel 2 are flush with the outer surfaces of the aluminum alloy threshold body 1. The decorative outer panel 2 of this application uses FRP board, which has high structural strength, wear resistance, anti-slip properties, and long service life. Moreover, after installation, the entire decorative outer panel 2 is flush with the outer surface of the aluminum alloy threshold. When multiple modules are installed, adjacent decorative outer panels 2 are installed without gaps, abutting against each other. The decorative outer panels 2 are inserted into the aluminum alloy threshold body 1 in the width direction and then mutually restrained and limited in the length direction to form a whole. This installation method is simple and convenient.

[0032] Furthermore, the bottom of both slide groove 11 and slide groove 2 12 is flush with the lower side wall of the corresponding slot 13. The slots 13 distributed on slide groove 11 and slide groove 2 12 are all in contact with the bottom of slide groove 11 and slide groove 2 12, which facilitates the sliding of the rib 21 and the alignment and engagement of the locking part 22 with the slot 13, making installation convenient.

[0033] Furthermore, the fit between the decorative outer panel 2 and the aluminum alloy threshold body 1 is less than 1mm. When the FRP board is inserted into the threshold of the subway platform screen door, the structure fits tightly, and the gap after insertion is less than 1mm.

[0034] Furthermore, there is a movable gap 14 between the sidewalls of the first groove 11 and the second groove 12 and the side of the rib 21. The rib 21 of this application has a movable gap 14 in the lateral direction with the first groove 11 and the second groove 12. Such a movable gap 14 will not affect the movement of a single decorative outer panel 2, because adjacent decorative outer panels 2 abut against each other. The design of the movable gap 14 allows for a certain amount of space to smoothly insert the decorative outer panel 2 during installation. At the same time, during use, the movable gap 14 allows the entire decorative panel to move slightly in the width assembly direction to accommodate thermal expansion and contraction or movement under special circumstances.

[0035] Furthermore, the aluminum alloy door sill body 1 has two hollow cavities 15. The two hollow cavities 15 are located at both ends of the length direction of the aluminum alloy door sill body 1. The design of multiple hollow cavities 15 allows the aluminum alloy door sill body 1 to minimize material usage while ensuring its structural strength, effectively saving material costs.

[0036] Furthermore, a groove 16 is provided at the bottom of the aluminum alloy door sill body 1 in the middle area, and a support part 17 protrudes from the groove opening of the groove 16. The aluminum alloy door sill body 1 of this application has a groove 16 at the bottom, which can reduce the material and meet the installation clearance requirements, so that the support part 17 can be better buried in the ground and has better fixing strength to the ground.

[0037] A subway platform screen door threshold includes several of the aforementioned subway platform screen door threshold modules. The aluminum alloy threshold bodies 1 of two adjacent threshold modules abut against each other in the length direction. When the decorative outer panel 2 is engaged with the aluminum alloy threshold body 1, adjacent decorative outer panels 2 also abut against each other in the length direction. The entire platform screen door threshold is formed by horizontally assembling the aforementioned threshold modules. Adjacent aluminum alloy threshold bodies 1 abut against each other, and decorative outer panels 2 can be inserted and engaged in the width direction. In the length direction, the decorative outer panels 2 abut against each other, providing a limiting effect. This design significantly reduces installation steps, lowers costs, increases efficiency, and is very convenient for installation. This utility model optimizes and improves the materials and structure of the original subway platform screen door threshold and protective outer panel. The subway platform screen door threshold adopts a one-piece aluminum alloy molding design, and the decorative outer panel 2 uses FRP board. The subway platform screen door threshold has slots 13 on both sides and a guide groove in the middle; the FRP board has L-shaped structures at both ends, which can be inserted into the slots 13 on both sides of the subway platform screen door threshold. It can fix FRP boards, has a safe structure and convenient installation performance, and also has good aesthetics.
