Description
Technical Field
[0001] This utility model relates to the field of railway equipment technology, specifically to a ground marking screen. Background Technology
[0002] Ground signage screens are typically placed on the ground to display information. For example, railway platforms will have some smart landmark screens at the corresponding positions of each train door to display train arrival information, stopping location information, and other safety reminders.
[0003] Current ground signage screens generally adopt an integrated structure, with glass and sealing gaskets laid layer by layer, and then squeezed and sealed. The sealing effect is limited, and there is still a possibility of water leakage.
[0004] When installing ground signage screens, a trench is usually dug at a designated location. The signage screen is then placed in the trench to check if its height is level with the ground. Any uneven areas are then corrected in the trench until the surface of the signage screen is level with the ground. This process is very cumbersome.
[0005] Moreover, after the ground signage screen is installed, water is prone to seepage at the joint between the outer ring and the ground. Once the water seeps to the bottom of the signage screen, it will threaten the circuitry at the bottom. Utility Model Content
[0006] To address the technical problems existing in the background art, this utility model provides a ground marking screen.
[0007] The technical solution of this utility model is as follows:
[0008] A ground marking screen includes a detachable lower bracket and an upper bracket. The upper bracket is U-shaped, with an inner support, a display device, and an acrylic glass arranged sequentially from bottom to top on the bottom. The sides of the acrylic glass are sealed to the upper bracket by a second sealing gasket, and the two sides of the upper surface are sealed to the upper bracket by glass glue. Tempered glass is fastened to the top of the upper bracket by a clamping member. A first sealing gasket is provided at the contact point between the tempered glass and the two sides of the upper bracket. The two ends of the upper bracket are sealed to a sealing plate by a third sealing gasket.
[0009] In this design, the width of the tempered glass is greater than that of the acrylic glass, which in turn is greater than the width of the display device. A three-layer sealing system—a first sealing gasket, glass adhesive, and a second sealing gasket—is used. This design makes it difficult for seeping water to reach the central display device. Furthermore, the three sealing layers lock in water from the top, bottom, and vertical surfaces, providing multi-dimensional waterproofing and significantly improving the waterproofing effect compared to existing technologies.
[0010] In one implementation, the lower support includes two symmetrically arranged first side plates and a first base plate connected to the bottom. The outer end faces of both sides of the upper support are provided with slots, and the first side plates are inserted into the slots to connect with the upper support. This detachable design allows the lower support to be removed and connected to the upper support after it has been leveled with the ground, making it convenient to operate, labor-saving, and easy to maintain later.
[0011] As a preferred embodiment, the first base plate comprises alternating high and low plates with a gap between the joints of the high and low plates, and the bottom edge of the first side plate has a corresponding staggered shape. This creates a water retention area at the bottom of the lower support, allowing the display device to be placed on the upper support and thus isolated from water seeping into the bottom of the lower support.
[0012] As a further preferred option, an adjusting component is provided on the lower plate of the first base plate for leveling the lower support. The upper surface of the adjusting component is lower than the upper plate to avoid interference with the upper support. This adjusting component allows for independent leveling of the lower support without needing to modify the groove shape, saving labor costs and improving installation efficiency.
[0013] In one embodiment, the upper support includes second side plates on both sides and a second bottom plate at the bottom. The upper width of the inner side of the second side plate is greater than the lower width, and an inner support platform is formed at the junction. Acrylic glass is supported on the inner support platform.
[0014] The inner support can be an inverted U-shaped structure, which is fastened to the second base plate. The bottom is connected to the display device by bolts. The display device can be a common LED screen. Several heat dissipation holes are provided at the connection between the inner support and the LED screen.
[0015] Preferably, the gaps between the two ends of the inner support and the second base plate are sufficient to accommodate the controller. To further increase the space at both ends, a reinforcing section can be provided above the second base plate, avoiding the positions at both ends of the second base plate. In this way, the second base plate can form a larger installation space with the inverted U-shaped inner support at both ends.
[0016] As a preferred technical solution, having a flush outer surface of the ground signage screen facilitates carrying, placement, and installation. Therefore, the depth of the outer slot of the upper bracket is consistent with the thickness of the first side plate of the lower bracket, and an outer support platform is provided on the outer side of the second side plate above the slot, with the clamping component located on the outer support platform. This ensures that the clamping component, the outer support platform, and the outer surface of the first side plate are flush.
[0017] Specifically, the clamping component can be a right-angle bent component arranged in an inverted L shape. Several bolt holes are opened along its length. After installation, one side is attached to the upper outer side of the second side plate, and the other side is used to press the tempered glass. It is connected to the second side plate by fasteners.
[0018] Regarding the installation of the first gasket, in order to minimize the amount of water reaching the position of the first gasket, a groove is provided along the length direction in the middle of the top end of the second side plate, and the first gasket is inserted therein. The height of the first gasket is about 0.5 cm higher than the top end of the second side plate. In this way, the first gasket is located inside the tempered glass, and the proportion of water seeping down from the tempered glass flowing inward is relatively small. Secondly, due to the design of the groove, after the water contacts the first gasket, it preferentially flows down along the first gasket to the groove position and then flows outwards after being blocked. Therefore, the penetration of water through the first gasket can be effectively controlled.
[0019] Regarding the sealing of the side of the ground sign board, the third gasket can adopt a shape like a Chinese character 'Ri', where the three horizontal sides respectively correspond to the tempered glass, the plexiglass, and the bottom edge of the upper bracket, and the two vertical sides respectively correspond to the two side edges of the upper bracket.
[0020] Through the above design, in the ground sign board of the present utility model, the width of the tempered glass is greater than the width of the plexiglass, and the width of the plexiglass is greater than the width of the display device, and the first gasket, glass glue, and the second gasket are respectively used for sealing in three layers. On the one hand, it is difficult for the water seeping down to flow towards the position of the middle display device. On the other hand, the three sealing layers respectively lock the water on the top surface, the bottom surface, and the vertical surface, providing multi-dimensional waterproofing, and the waterproof effect has been greatly improved compared with the prior art.
[0021] The separable design of the upper and lower brackets allows the lower bracket to be leveled with the ground first, and then taken out and connected to the upper bracket, which is convenient for operation, labor-saving, and便于后期维护. Moreover, the method of separately adjusting the lower bracket does not require correcting the shape of the groove, saving labor costs and提高了安装效率.
[0022] The design of the staggered heights at the bottom of the lower bracket can form a water accumulation area at the bottom of the lower bracket, and the display device is placed on the upper bracket, thus isolating it from the water seeping down to the bottom of the lower bracket.

[0036] See Figures 1-4 As shown, this embodiment provides a ground signage screen, including a detachably connected lower support 1 and an upper support 2. The upper support 2 is U-shaped, and from bottom to top, an inner support 5, a display device, and an acrylic glass 7 are arranged sequentially. The sides of the acrylic glass 7 are sealed to the upper support 2 through a second sealing gasket 71, and the two sides of the upper surface are sealed to the upper support 2 through glass glue 72. The top of the upper support 2 is clamped with a tempered glass 8 by a clamping member 3. A first sealing gasket 26 is provided at the contact point between the tempered glass 8 and the two sides of the upper support 2. The two ends of the upper support 2 are sealed to the sealing plate 4 through a third sealing gasket 9.
[0037] In this design, the width of tempered glass 8 is greater than the width of acrylic glass 7, and the width of acrylic glass 7 is greater than the width of the display device. It is sealed in three layers using a first sealing gasket 26, glass adhesive 72, and a second sealing gasket 71. This design makes it difficult for seeping water to reach the central display device. Furthermore, the three sealing layers lock in water from the top, bottom, and vertical surfaces, providing multi-dimensional waterproofing and significantly improving the waterproofing effect compared to existing technologies.
[0038] The following is combined with Figure 5 and Figure 6Let's introduce the specific structure of the bracket. The lower bracket 1 is U-shaped, including two symmetrically arranged first side plates 11 and a first base plate 12 connected to the bottom. Rectangular notches are provided at the upper ends of both first side plates by removing material. Slots 23 are provided on the outer end faces of both sides of the upper bracket 2. The first side plates 11 are inserted into the slots 23 to connect with the upper bracket 2, while the two ends of the upper bracket 2 are inserted into the rectangular notches. By designing the thickness of the slots 23 and the size of the rectangular notches, the outer end faces of the upper bracket 2 are flush with the two end faces after the lower bracket 1 is inserted.
[0039] Moreover, the detachable design of the local ground signage screen allows it to be removed and connected to the upper bracket 2 after the lower bracket 1 is leveled with the ground, which is convenient to operate, saves effort, and facilitates later maintenance.
[0040] As a preferred embodiment, the first base plate 12 includes alternating high and low plates with no connecting parts at the joint ends, thus forming a gap. The bottom edge of the first side plate 11 has a corresponding staggered shape. In this way, a water retention area can be formed at the bottom of the lower support 1, and the display device is placed on the upper support 2, thereby isolating it from water seeping down to the bottom of the lower support 1 and preventing it from affecting the circuit.
[0041] As a further preferred embodiment, an adjusting member 13 is provided on the lower plate of the first base plate 12 for leveling the lower support 1. The adjusting member 13 can be a rectangular block structure with bolt holes, and corresponding openings are provided on the lower plate to facilitate bolt passage.
[0042] The upper surface of the adjusting component 13 is lower than the height of the high plate to avoid interference with the upper bracket 2. The design of the adjusting component 13 allows for independent leveling of the lower bracket 1 without needing to modify the groove shape, saving labor costs and improving installation efficiency.
[0043] To better support the upper bracket 2, both ends of the first base plate 12 are low plates, each equipped with an adjustment piece 13. Connectors are also installed at the bottom of the rectangular notches in the two first side plates 11, with the height of the connectors flush with the high plates, thus jointly supporting the upper bracket 2.
[0044] See Figure 7 and Figure 8 In this embodiment, the upper support 2 includes second side plates 21 on both sides and a second bottom plate 22 at the bottom. The upper width of the inner side of the second side plate 21 is greater than the lower width, and an inner support platform 25 is formed at the junction. Acrylic glass 7 is supported on the inner support platform 25.
[0045] The inner support 5 can be an inverted U-shaped structure, fastened to the second base plate 22, and connected to the display device at the bottom by bolts. The display device can be a common LED screen 6. Several heat dissipation holes are provided at the connection between the inner support 5 and the LED screen 6. The space between the lower part of the inner support 5 and the second base plate 22 can be used for heat dissipation of the LED screen 6.
[0046] Preferably, the gaps between the two ends of the inner support 5 and the second bottom plate 22 can accommodate the controller. To further increase the space at both ends, a reinforcing portion can also be provided above the second bottom plate 22, and the reinforcing portion avoids the positions at both ends of the second bottom plate 22. In this way, a larger installation space can be formed between the second bottom plate 22 and the inverted U-shaped inner support 5 at both ends. At the same time, the bending difficulty of the inner support 5 can be reduced, which is convenient for processing.
[0047] As a preferred technical solution, the outer end face of the ground marking screen is flush, which is more convenient for carrying, placing, and installing. Therefore, the depth of the outer slot 23 of the upper bracket 2 is the same as the thickness of the first side plate 11 of the lower bracket 1. An outer support platform 24 is provided above the slot 23 on the outside of the second side plate 21, and the pressing member 3 is located on the outer support platform 24. And the pressing member 3, the outer support platform 24, and the outer surface of the first side plate 11 are flush.
[0048] See Figure 2 and Figure 3 As shown, the pressing member 3 can be a right-angle bending member, arranged in an inverted L shape. A plurality of bolt holes are opened along its length direction. After installation, one side is closely attached to the upper outer side surface of the second side plate 21, and the other side presses the tempered glass 8, and is connected to the second side plate 21 through fasteners.
[0049] Preferably, after the pressing member 3 is installed, the vertical portion abuts against the outer support platform 25. In this way, it is convenient to use a pressing device to press down the installation bolts of the pressing member 3, and at the same time, the tempered glass will not be damaged.
[0050] See Figure 3 As shown, regarding the installation of the first gasket 26, in order to minimize the amount of water reaching the position of the first gasket 26, a groove is opened along the length direction in the middle of the top end of the second side plate 21, and the first gasket 26 is inserted therein. The height of the first gasket 26 is about 0.5 cm higher than the top end of the second side plate 21. In this way, the first gasket 26 is located inside the tempered glass 8, and the proportion of water flowing inward from the permeated water of the tempered glass 8 is less. Secondly, due to the design of the groove, after the water contacts the first gasket 26, it preferentially flows downward along the first gasket 26 to the groove position and then flows outwards after being blocked. Therefore, the water penetration through the first gasket 26 can be effectively controlled.
[0051] See Figure 9 and Figure 10 As shown in [relevant figure numbers], regarding the sealing of the side of the ground marking screen, the sealing plate 4 adopts a rectangular cover style, with bolt holes opened on both sides. Corresponding bolt holes are opened on the second side plate 21 of the upper bracket 2 for connection. A sealing groove for connecting the third gasket 9 is opened on the back of the sealing plate 4. The third gasket 9 can adopt a Japanese character shape. Among them, the three horizontal sides respectively correspond to the tempered glass 8, the plexiglass 7, and the bottom edge of the upper bracket 2, and the two vertical sides respectively correspond to the two side edges of the upper bracket 2.
[0052] Preferably, the two vertical edges of the third sealing gasket 9 are located inside the bolt holes opened on the second side plate 21 of the upper bracket 2 to ensure the sealing effect.
