Description

Technical Field

[0001] This utility model relates to the field of shielding door technology, and in particular to a chassis and shielding door that are easy to assemble. Background Technology

[0002] In modern urban rail transit systems, platform screen doors effectively reduce the risk of passengers accidentally falling onto the tracks by physically separating the platform from the track area. At the same time, platform screen doors also have significant commercial value, often featuring advertising panels that generate additional economic benefits for the urban rail transit system.

[0003] In traditional chassis designs, the assembly process is often cumbersome and complex. On one hand, connecting the advertising board to the frame typically requires numerous screws, nuts, and other fasteners for fixing. This not only makes installation time-consuming and labor-intensive, but also leads to thread wear from repeated tightening of screws during subsequent disassembly and replacement, affecting the stability of the connection. Furthermore, it fails to effectively guarantee a secure connection between the advertising board and the frame after installation, resulting in an overall chassis structure that is not robust enough. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a chassis and shielding door that are easy to assemble. The panel of the chassis can be easily connected to the frame, and then the panel and the frame are connected and limited by the connection of the cover plate. The assembly is convenient and the separation of the panel and the frame is avoided.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] An easy-to-assemble chassis, comprising,

[0007] A connecting component, including a first connector and a second connector;

[0008] A chassis assembly includes a frame, a front panel, and a cover plate. The front panel is detachably mounted to the side of the frame via a first connector, and the cover plate is detachably mounted to the top of the frame and the front panel via a second connector.

[0009] Therefore, by connecting the cover plate to the frame, the upward movement of the panel can be restricted. This simplifies the connection structure between the panel and the frame, meaning the first connector does not need to perform both connection and limiting functions, but only needs to fulfill the connection function, simplifying the connection operation between the frame and the panel; while the further limiting function is achieved by the connection between the cover plate and the frame.

[0010] Furthermore, the side of the frame is provided with a first connecting surface, and the first connecting member is disposed on the first connecting surface; the panel is provided with a second connecting surface, the second connecting surface is provided with a first connecting portion, and the first connecting portion is connected to the first connecting member so that the second connecting surface is in contact with the first connecting surface.

[0011] Therefore, by fitting the second connecting surface with the first connecting surface, the reliability of the connection between the panel and the frame can be improved. At the same time, the connection structure after the first connecting part and the first connecting piece are connected can be hidden on the back of the panel, avoiding damage such as collisions and wear that may occur to the exposed connection structure, and extending its service life.

[0012] Furthermore, the first connector includes a connecting segment and a hooking segment. The connecting segment connects the hooking segment to the first connecting surface. The hooking segment and the first connecting surface are spaced apart to form a hooking interval. The hooking segment has a guide surface on the side facing the hooking interval for guiding the first connecting part to hook onto the hooking interval from top to bottom.

[0013] Thus, by creating a hanging interval between the hanging section and the first connecting surface, a hanging space is provided for the first connecting part, enabling the first connecting part to be quickly and accurately hung there, thereby achieving a detachable connection between the panel and the frame.

[0014] Furthermore, the panel component includes a first frame and a panel, the top of the first frame extends inward to form a connecting edge, the connecting edge forms the first connecting portion, and the second connecting surface is formed on one side of the connecting edge; the panel is fixed to the side of the first frame away from the second connecting surface.

[0015] Furthermore, the bottom end of the first frame is provided with a hook edge, and the first connecting surface is also provided with a second connecting boss. The hook edge is used to abut against the inner side of the second connecting boss when the panel is connected to the frame.

[0016] Therefore, after the connecting edge is connected to the hanging interval, the downward movement of the panel is restricted; after the hanging edge is connected to the inner side of the second connecting boss, the movement of the panel away from the frame is restricted; and after the cover plate is connected to the frame, the upward movement of the panel is restricted. Thus, the panel is limited from three positions, ensuring its stability when connected to the frame.

[0017] Furthermore, the frame is provided with a third connecting surface, the third connecting surface is provided with a first connecting boss, and the first connecting boss is provided with a second connecting part; the cover plate includes a second frame and a cover plate connected to one side of the second frame, the cover plate covers the top of the first connecting boss, and the second frame surrounds the outer periphery of the first connecting boss; the second frame is provided with a third connecting part, and the third connecting part is connected to the second connecting part through the second connector.

[0018] Therefore, by connecting the cover plate to the frame through the second connector, on the one hand, the electronic equipment inside the chassis can be sealed to prevent dust and moisture from entering the chassis; on the other hand, the connection between the cover plate and the frame can lock the connection between the panel and the frame to prevent them from separating; at the same time, after the cover plate and the frame are separated, the panel and the frame can be easily removed, making the overall assembly or disassembly of the chassis convenient and fast.

[0019] Furthermore, the bottom end of the second frame is provided with an abutment edge, which abuts against the third connecting surface and the top of the panel component.

[0020] Therefore, by extending the bottom of the second frame inward to form an abutment edge, the pressing area of ​​the second frame can be increased, so that the abutment edge can press against the top of the third connecting surface and the panel piece at the same time. This can further reduce the gaps in the chassis and make the pressure distribution more uniform, thus improving the firmness.

[0021] Furthermore, the frame is provided with an installation cavity, which includes a first installation section and a second installation section. The first installation section is provided with a driving mechanism, and the second installation section is provided with a door panel mechanism. The driving mechanism is used to drive the door panel mechanism to enter or extend into the second installation section. The middle part of the first connecting boss is provided with a through groove, which communicates with the first installation section.

[0022] Therefore, the chassis of this utility model can accommodate components such as the drive mechanism and the gate mechanism in separate sections, and allows the gate mechanism to move within the mounting cavity; at the same time, a through groove is provided at the top of the frame to connect to the first mounting section, so that the drive mechanism 30 in the first mounting section can be inspected and maintained after the cover plate is removed.

[0023] Furthermore, the second connecting element is a screw or a pin.

[0024] Therefore, after the panel is connected to the frame and the cover is connected to the frame, only the second connector used to connect the cover to the frame is exposed outside the chassis.

[0025] A shielding door includes a gate mechanism and a chassis as described above for easy assembly. The chassis is provided with a drive mechanism for driving the gate mechanism to move.

[0026] In summary, the easily assembled chassis and shielding door provided by this utility model have the following technical effects:

[0027] 1) This utility model achieves detachable installation of the panel and the side of the frame through the first connector. After the cover plate and the frame are detachably installed through the second connector, the cover plate is located on top of the frame and the panel. Since the relative position of the cover plate and the frame is restricted and fixed, the cover plate also restricts the panel from moving upward, thus locking the position of the panel.

[0028] 2) Since the cover plate provides upward upper limit for the panel after connecting to the frame, the first connector does not need to perform both connection and limit functions; it only needs to fulfill the connection function, simplifying the connection operation between the frame and the panel. Furthermore, the panel can be quickly detached after the cover plate is removed, enabling quick disassembly and assembly of the chassis. Attached Figure Description

[0040] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0043] Example 1

[0044] See Figure 1 and Figure 2 This utility model discloses a chassis 10 that is easy to assemble, which includes a connecting assembly and a chassis assembly. Specifically, the connecting assembly includes a first connector 14 and a second connector 15; see reference. Figure 2 The chassis assembly includes a frame 11, a panel 12, and a cover 13. The panel 12 is detachably mounted to the side of the frame 11 via a first connector 14, and the cover 13 is detachably mounted to the top of the frame 11 and the panel 12 via a second connector 15.

[0045] Based on this structure, when using the easily assembled chassis 10 of this utility model, during the assembly of the chassis 10, first place the panel 12 close to the side of the frame 11 and connect it to the frame 11 through the first connector 14. Then, place the cover plate 13 close to the top of the frame 11 and connect it to the frame 11 through the second connector 15.

[0046] In some embodiments, the panel 12 is connected to and positioned by the first connector 14 after being installed on the frame 11, and the panel 12 is securely connected to the frame 11. The cover plate 13 is also connected to and positioned by the second connector 15 after being installed on the frame 11, and the cover plate 13 is securely connected to the frame 11.

[0047] In this embodiment, after the panel 12 is installed to the frame 11 via the first connector 14, only a connection is achieved. For example, the panel 12 is hung or inserted onto the frame 11 from top to bottom via the first connector 14. It still has a certain degree of freedom of movement along the installation direction and may be displaced due to external forces, leading to shaking or detachment. After the cover plate 13 is connected to the frame 11, the cover plate 13 is located at the top of the frame 11 and the panel 12. Since the relative position of the cover plate 13 and the frame 11 is restricted and fixed, the cover plate 13 can restrict the upward movement of the panel 12 and lock the position of the panel 12. When the chassis 10 is subjected to external impact or vibration, it can prevent the panel 12 from detaching from the frame 11.

[0048] It should be noted that the installation and disassembly sequence of the panel 12 and the cover plate 13 is fixed. During installation, the panel 12 is connected to the frame 11 first, and then the cover plate 13 is connected to the frame 11. During disassembly, the cover plate 13 is separated from the frame 11 first, and then the panel 12 is separated from the frame 11.

[0049] Thus, by connecting the cover plate 13 to the frame 11, the frame 11 and the panel 12 are further fixed. This simplifies the connection structure between the panel 12 and the frame 11, meaning the first connector 14 does not need to perform both connection and limiting functions; it only needs to fulfill the connection function, simplifying the connection operation between the frame 11 and the panel 12. The further limiting function is achieved by connecting the cover plate 13 to the frame 11. Simultaneously, the first connector 14 enables a detachable connection between the panel 12 and the side of the frame 11, facilitating quick removal of the panel 12 after removing the cover plate 13.

[0050] When disassembling the chassis 10, first remove the second connector 15, disconnect the cover plate 13 from the frame 11, and then remove the cover plate 13 from the top of the frame 11. At this time, the connection between the panel 12 and the frame 11 can be disconnected.

[0051] Understandably, after removing the cover plate 13, maintenance personnel can reach into the frame 11 from above to operate on the internal drive mechanism 30 or wiring. After further removing the panel 12, maintenance personnel can operate on the internal drive mechanism 30 or wiring from the side of the frame 11. At this time, the side of the frame 11 has a larger operating space, making it easier for operators to perform maintenance, wiring, and other operations.

[0052] The panel 12, which can be an advertising board, information board, etc., is located on the side of the housing 10. When the housing 10 is used in the platform screen door system of a station, the screen door can extend its gates to block the station passage. The panel 12 on the side of the housing 10 faces the waiting passengers on the platform and can display advertisements or directional information. In this way, while the platform screen door separates the platform from the tracks to ensure waiting safety, it allows passengers to see the advertising content directly, increasing the commercial revenue of urban rail transit. Regarding the display of directional information, timely updates to passenger guides, route adjustment notices, safety tips, etc., can greatly improve the passenger travel experience, help passengers quickly obtain key information, and reduce travel inconvenience caused by unclear information.

[0053] In this way, the components of the chassis 10 can be detachably connected through the connecting components. Compared with the traditional welding or non-detachable fixing methods, this greatly improves the assembly efficiency and reduces the installation difficulty.

[0054] For further details, please refer to [link / reference]. Figure 3 The frame 11 has a first connecting surface 111 on its side, and the first connector 14 is disposed on the first connecting surface 111. (See reference...) Figure 4 The panel 12 is provided with a second connecting surface 121, and the second connecting surface 121 is provided with a first connecting part 122, wherein the first connecting part 122 is connected to the first connecting member 14 so that the second connecting surface 121 is in contact with the first connecting surface 111.

[0055] Based on this structure, when assembling the panel 12, the second connecting surface 121 of the panel 12 is first brought closer to the first connecting surface 111 of the frame 11, and then the first connecting part 122 on the second connecting surface 121 is connected to the first connecting member 14 on the first connecting surface 111.

[0056] After the first connecting part 122 is connected to the first connecting member 14, the second connecting surface 121 is attached to the first connecting surface 111, thus achieving the connection between the panel 12 and the frame 11. Therefore, by attaching the second connecting surface 121 to the first connecting surface 111, the connection reliability between the panel 124 and the frame 11 can be improved. Simultaneously, the connection structure after the first connecting part 122 and the first connecting member 14 are connected can be hidden on the back of the panel 12, avoiding potential damage from impacts, wear, etc., and extending its service life.

[0057] After the cover plate 13 is connected to the frame 11 via the second connector 15, only the second connector 15 is exposed on the outside of the chassis 10. Compared to multiple connectors being exposed separately, having only one connector exposed makes it easier for maintenance personnel to quickly identify the disassembly and assembly parts, making the maintenance process clearer, reducing the risk of damage caused by misoperation, and improving maintenance efficiency.

[0058] The first connector 14 is disposed on the upper part of the first connecting surface 111, and the first connecting part 122 is disposed on the upper part of the second connecting surface 121. After the panel 12 and the frame 11 are connected to the first connector 14 through the first connecting part 122, the upper part of the panel 12 is connected to the upper part of the frame 11, and the lower part of the panel 12 approaches and adheres to the lower part of the frame 11 under the action of gravity, so that the second connecting surface 121 adheres to the first connecting surface 111.

[0059] In addition, the cover plate 13 is also placed on the top of the frame 11 and the panel 12, which can shield the mating part of the second connecting surface 121 and the first connecting surface 111. Dust and rainwater from outside the chassis 10 will not enter the mating part of the second connecting surface 121 and the first connecting surface 111, and will not damage the first connector 14.

[0060] Further, see Figure 5 as well as Figure 9 The first connector 14 includes a connecting segment 141 and a hanging segment 142. Specifically, the connecting segment 141 connects the hanging segment 142 and the first connecting surface 111 respectively. The hanging segment 142 and the first connecting surface 111 are spaced apart to form a hanging interval 143. The hanging segment 142 is provided with a guide surface 144 on the side facing the hanging interval 143 for guiding the first connecting part 122 to be hung on the hanging interval (143) from top to bottom.

[0061] Based on this structure, when assembling the panel 12, the first connecting part 122 on the panel 12 can be inserted into the hanging interval 143 from top to bottom. The guide surface 144 can be an inclined surface. As the first connecting part 122 moves down, the guide surface 144 will gradually guide it into the hanging interval 143 until the first connecting part 122 is embedded in the bottom of the hanging interval 143, while the first connecting surface 111 and the second connecting surface 121 are in contact.

[0062] Thus, by forming a hanging interval 143 between the hanging section 142 and the first connecting surface 111, a hanging space is provided for the first connecting part 122, so that the first connecting part 122 can be quickly and accurately hung there, realizing the detachable connection between the panel 12 and the frame 11.

[0063] It should be noted that after the panel piece 12 is connected to the first connector 14 via the first connecting part 122, there is still a risk that the panel piece 12 will detach from the frame 11. However, after the cover plate piece 13 is connected to the frame 11, the first connecting part 122 cannot detach upward from the hook interval 143 because the top of the panel piece 12 is pressed against by the cover plate piece 13, thus ensuring a reliable connection between the panel piece 12 and the frame 11.

[0064] The way the first connector 14 and the first connecting part 122 cooperate makes it easy to disconnect the panel 12 by simply lifting the first connecting part 122 upwards when it is necessary to disassemble it. The operation is simple and convenient, and it is convenient for later maintenance and replacement.

[0065] In addition, the first connector 14 can also be a connecting protrusion provided on the second connecting surface 121, and a corresponding groove is provided on the first connecting surface 111. The panel 12 is connected by snapping the connecting protrusion into the groove on the frame 11, and the connection between the cover plate 13 and the frame 11 restricts the connecting protrusion from disengaging from the groove.

[0066] Further, see again Figure 4 The panel component 12 includes a first frame 123 and a panel 124. Specifically, the top of the first frame 123 extends inward to form a connecting edge, and the connecting edge forms the first connecting portion 122, while a second connecting surface 121 is formed on one side of the connecting edge. The panel 124 is fixed to the side of the first frame 123 away from the second connecting surface 121.

[0067] Based on this structure, during assembly, the panel 124 can be first fixed to the first frame 123, and then the assembled panel 12 can be brought close to the frame 11, so that the second connecting surface 121 of the connecting edge faces the first connecting surface 111 of the frame 11. Since the hooking section 142 of the first connector 14 forms a hooking interval 143 with the first connecting surface 111, and the hooking section 142 is provided with a guide surface 144, the connecting edge can be aligned with the hooking interval 143 from top to bottom. Under the action of the guide surface 144, the connecting edge can be smoothly inserted into the hooking interval 143. As the connecting edge is hooked deeper, the second connecting surface 121 gradually fits against the first connecting surface 111, further enhancing the stability of the connection.

[0068] Among them, see Figure 3 as well as Figure 9 The first connector 14 includes two oppositely arranged connecting segments 141 and two oppositely arranged hanging segments 142 along the length direction of the frame 11, and the two connecting segments 141 and the two hanging segments 142 are connected by a connecting plate 145. Multiple first connectors 14 can also be provided along the length direction of the frame 11, allowing the panel 12 to directly form multi-point hanging connections with the frame 11. These multi-point hanging connections jointly support and connect the panel 12, ensuring the stability of the hanging connection.

[0069] Furthermore, the side of the first frame 123 furthest from the second connecting surface 121 also extends inward to form a limiting frame, so that the panel 124 can be installed within the space enclosed by the first frame 123, and the outer side of the panel 124 abuts against the limiting frame. When it is necessary to change the advertising information or guidance information on the panel 124, the first frame 123 can be removed, and then the panel 124 can be taken out for replacement.

[0070] In addition, the first connector 14 can be a hooking protrusion extending along the length of the frame 11, in addition to the connection structure described above. One side of the hooking protrusion is connected to the first connecting surface 111, and the other side of the hooking protrusion extends upward in a direction away from the first connecting surface 111, so that the other side of the hooking protrusion and the first connecting surface 111 are spaced apart to form a hooking interval 143. The hooking edge 125 at the upper end of the panel 12 can be hooked along the hooking protrusion to the hooking interval 143.

[0071] Further, see Figure 4 The bottom of the first frame 123 is provided with a hanging edge 125, see reference. Figure 3 The first connecting surface 111 is also provided with a second connecting boss 114. (See attached image.) Figure 5 The mounting edge 125 is used to abut against the inner side of the second connecting boss 114 when the panel 12 is connected to the frame 11.

[0072] Based on this structure, when connecting the panel 12 and the frame 11, the connecting edge at the top of the first frame 123 is first aligned with the hooking interval 143 on the frame 11, and the hooking edge 125 at the bottom of the first frame 123 is aligned with the outer side of the second connecting boss 114. When the connecting edge moves downward into the hooking interval 143, the hooking edge 125 moves along the outer side of the second connecting boss 114 into its inner side, and after the connecting edge and the hooking interval 143 are connected in place, it abuts against the inner side of the second connecting boss 114.

[0073] The second connecting boss 114 is located in the middle of the first connecting surface 111, and the second connecting boss 114 is located below the first connecting member 14.

[0074] Thus, after the connecting edge is connected to the hanging interval 143, the downward movement of the panel piece 12 is restricted; after the hanging edge 125 is connected to the inner side of the second connecting boss 114, the movement of the panel piece 12 away from the frame 11 is restricted; and after the cover plate piece 13 is connected to the frame 11, the upward movement of the panel piece 12 is restricted. Thus, the panel piece 12 is limited from three aspects, ensuring its stability when connected to the frame 11.

[0075] Further, see again Figure 3 The frame 11 has a third connecting surface 112, and the third connecting surface 112 has a first connecting boss 16, and the first connecting boss 16 has a second connecting portion 161. (See reference...) Figure 6 The cover plate 13 includes a second frame 132 and a cover plate 133 connected to one side of the second frame 132. Specifically, the cover plate 133 covers the top of the first connecting boss 16, and the second frame 132 surrounds the outer periphery of the first connecting boss 16. The second frame 132 is provided with a third connecting part 131, and the third connecting part 131 is connected to the second connecting part 161 through a second connector 15.

[0076] Based on this structure, when assembling the cover plate 13, the cover plate 13 can be placed close to the top of the frame 11 and covered on the first connecting boss 16. Then, the second connecting part 161 and the third connecting part 131 are aligned and connected by the second connecting member 15.

[0077] For details, please refer to Figure 7 Both the second connecting part 161 and the third connecting part 131 can be connecting holes. The second connecting member 15 is a screw, connecting pin, etc. After the second connecting member 15 passes through the third connecting part 131 and the second connecting part 161 in sequence, the connection between the cover plate 13 and the frame 11 is realized.

[0078] Therefore, by connecting the cover plate 13 and the frame 11 through the second connector 15, on the one hand, the electronic equipment inside the chassis 10 can be sealed to prevent dust and moisture from entering the chassis 10; on the other hand, the connection between the cover plate 13 and the frame 11 locks the connection between the panel piece 12 and the frame 11 to prevent them from separating; at the same time, after the cover plate 13 is separated from the frame 11, the panel piece 12 and the frame 11 can also be easily removed, making the overall assembly or disassembly process of the chassis 10 very convenient and fast.

[0079] Further, see Figure 6 The bottom of the second frame 132 is provided with an abutment edge 134, see reference. Figure 6 The abutment edge 134 abuts against the third connecting surface 112 and the top of the panel piece 12.

[0080] The abutment edge 134 can be integrally formed by extending inward from the bottom end of the second frame 132, or it can be a separate square component that is connected to the bottom end of the second frame 132 by welding.

[0081] Therefore, after the second frame 132 is connected to the first connecting boss 16, the bottom of the second frame 132 can press against the top of the panel piece 12, forming a structure that clamps the panel piece 12 from both above and below with the first connecting member 14, effectively preventing vertical displacement of the panel piece 12. Furthermore, by providing an abutment edge 134 at the bottom of the second frame 132, the pressing area of ​​the second frame 132 can be increased, allowing the abutment edge 134 to simultaneously press against the third connecting surface 112 and the top of the panel piece 12. This further reduces the gaps in the chassis 10, makes the pressure distribution more uniform, and improves the robustness.

[0082] Further, see Figure 8 The frame 11 has a mounting cavity 113, which includes a first mounting section and a second mounting section. The first mounting section contains a drive mechanism 30, and the second mounting section contains a door mechanism 20. The drive mechanism 30 is used to drive the door mechanism 20 into or out of the second mounting section. (See reference...) Figure 3 The first connecting boss 16 has a through groove in the middle, and the through groove is connected to the first mounting section.

[0083] Based on this structure, see Figure 3 The mounting cavity 113 is provided with a mounting plate, which divides the mounting cavity 113 into a first mounting section and a second mounting section from top to bottom. When assembling the chassis 10, the drive mechanism 30 can be installed on the mounting plate first, with the drive mechanism 30 located in the first mounting section. Then, the door gate mechanism 20 can be installed in the second mounting section, and the drive end of the drive mechanism 30 can be connected to the door gate mechanism 20 for transmission.

[0084] In use, the drive mechanism 30 is activated, causing the gate mechanism 20 to extend out of the casing 10 through an opening on one side of the second mounting section. At this time, the gate mechanism 20 can block the passage. Alternatively, the drive mechanism 30 can pull the gate mechanism 20, which is located outside the casing 10, into the second mounting section.

[0085] The drive mechanism 30 includes a drive motor, two synchronous pulleys, and a synchronous belt. Specifically, the two ends of the synchronous belt are respectively arranged around the two synchronous pulleys. The drive motor drives one of the synchronous pulleys to rotate, thereby moving the synchronous belt. The gate mechanism 20 includes a mounting bracket and a gate. The gate is mounted on the mounting bracket, and the mounting bracket is connected to the synchronous belt through a clamp. Thus, when the drive motor rotates, the synchronous belt can drive the gate mechanism 20 to move.

[0086] Furthermore, since the drive mechanism 30 is installed in the first mounting section near the top, a through slot is provided at the top of the frame 11 to connect the first mounting section, so that the drive mechanism 30 in the first mounting section can be inspected and maintained after the cover plate 13 is removed.

[0087] Therefore, the chassis 10 of this utility model can accommodate components such as the drive mechanism 30 and the gate mechanism 20, and allow the gate mechanism 20 to move within the mounting cavity 113; on the other hand, it can display advertisements and present guidance information through the panel 12.

[0088] Furthermore, the second connector 15 is a screw or a pin.

[0089] In this way, during connection, the cover plate 13 is connected to the frame 11 by several screws, and after connection, only the second connector 15 is exposed on the outside of the chassis 10.

[0090] The second connector 15 can be provided in two sets, which respectively connect the second frame 11 of the cover plate 13 to both ends of the first connecting boss 16 of the frame 11. At this time, two screws are exposed on the outside of the chassis 10. In addition, snap-fit ​​parts and connecting holes can be provided at both ends of the first connecting boss 16, and a snap-fit ​​part can be provided on the inner side of the second frame 132 corresponding to the snap-fit ​​part, and a connecting hole can be provided at the other end.

[0091] Therefore, when the cover plate 13 is connected to the frame 11, one end of the cover plate 13 with a snap-fit ​​portion snaps into the snap-fit ​​component, and the snap-fit ​​portion is located inside the cover plate 13. The other end of the cover plate 13 with a connecting hole connects to the connecting hole on the first connecting boss 16 through the second connecting component 15. After connection, the screw head of the second connecting component 15 is exposed on the outside of the cover plate 13. At this time, only one screw is exposed outside the chassis 10, and both the panel 12 and the cover plate 13 form a firm connection with the frame 11.

[0092] Example 2

[0093] Unlike Embodiment 1, this embodiment discloses a shielding door, which includes a door gate mechanism 20 and a chassis 10 that is easy to assemble as in Embodiment 1. The chassis 10 is provided with a drive mechanism 30, and the drive mechanism 30 is used to drive the door gate mechanism 20 to move.

[0094] Based on this structure, when using the shielding door of this embodiment, during assembly, the drive mechanism 30 and the door panel mechanism 20 can be installed inside the frame 11 of the housing 10, and the drive mechanism 30 and the door panel mechanism 20 can be connected for transmission. Then, the panel 12 of the housing 10 is connected to the side of the frame 11 through the first connector 14, and the cover plate 13 is connected to the top of the frame 11 through the second connector 15.

[0095] When in use, the drive mechanism 30 can be activated. The drive mechanism 30 drives the gate mechanism 20 to extend out of the housing 10 through the opening at one end of the housing 10 via its transmission components. At this time, the gate mechanism 20 can block some passages, such as separating the platform from the track, to prevent passengers from accidentally falling onto the track when the train enters or leaves the station, thus playing a safety protection role.

[0096] When the motor of the drive mechanism 30 rotates in the reverse direction, the drive mechanism 30 drives the gate mechanism 20 to enter the housing 10 through the opening at one end of the housing 10 via its transmission components. At this time, the gate mechanism 20 opens the passage, and passengers can board the train from the platform.

[0097] The specific structure and usage of the drive mechanism 30, gate mechanism 20, and chassis 10 are described in detail in Embodiment 1, and will not be repeated here.

[0098] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
