Description

Technical Field

[0001] The present application relates to the field of display boards, and in particular to a mobile display board along a city street. Background Art

[0002] The architectural style along the street is an important window to show the image of the city. It records the changes of the entire street and presents a unique architectural language environment. The display boards along the street are important carriers to enhance the taste of the street and display different information.

[0003] At present, the display board mainly includes two opposite columns and a display board. The display board is located between the two opposite columns, and the display board is welded to the two opposite columns, while the columns are fixed by bolts pre-buried in the ground.

[0004] In actual use, since the bolts and nuts are exposed all year round, when the anti-rust paint on the bolts and nuts is worn, the bolts and nuts are easily damaged, thereby reducing the stability of the display board. Moreover, the exposed bolts are relatively sharp and can easily cause damage when people step on or hit them. Utility Model Content

[0005] In order to improve the problem of poor stability in fixing by exposed bolts and nuts, the present application provides a mobile display board along the street in a city.

[0006] The present application provides a mobile display board along the city street, which adopts the following technical solution:

[0007] A movable display board along a city street comprises a first column, a second column and a frame, wherein the frame is arranged between the first column and the second column, and the frame is used to install display materials; the first column and the second column are both installed in a foundation pit on the ground, a fixing plate is pre-buried in the foundation pit, a bottom plate is provided at the bottom of the first column and the bottom of the second column, the bottom plate covers the top of the fixing plate, a plurality of threaded holes are provided at the top of the fixing plate, screws are passed through the threaded holes, the screws extend upward and pass through the bottom plate; a nut is screwed on the screw, and the nut presses against the bottom plate.

[0008] By adopting the above technical solution, when the nut is tightened, the nut can form a pressing effect on the base plate, so that the base plate is reliably fixed on the fixing plate. In this way, the first column and the second column are fixed in the foundation pit, and then the cover plate is slid into the foundation pit to cover the foundation pit, thereby avoiding the screw and the nut from being in an exposed state, effectively improving the durability of the cooperation between the screw and the nut, and then improving the installation stability of the first column and the second column in the foundation pit.

[0009] Optionally, the base plate is provided with a plurality of through holes, and the plurality of through holes are dispersed around the first column and the second column, the through holes are arranged corresponding to the threaded holes, one end of the screw is connected to the threaded holes through threads, and the other end of the screw passes through the through holes and is close to the opening of the foundation pit.

[0010] By adopting the above technical solution, a base plate can be locked through the cooperation of multiple screws and nuts, thereby improving the locking effect of the base plate and ensuring that the first column and the second column can be in a reliably fixed state.

[0011] Optionally, a cover plate is provided on each of the first column and the second column, one cover plate slides on the outer side of the lower part of the first column, and the other cover plate slides on the outer side of the lower part of the second column; the end of the screw away from the threaded hole supports the cover plate, the top of the cover plate is flush with the opening of the foundation pit, and the surrounding walls of the cover plate are in contact with the surrounding walls of the foundation pit.

[0012] By adopting the above technical solution, when locking the nut, the cover plate is slid to the upper part of the first column or the second column, thereby increasing the operating space and facilitating operation. After the nut is locked, the cover plate is slid to the lower part of the first column or the second column, so that the cover plate can seal the foundation pit and effectively prevent external debris from entering the foundation pit. At the same time, it can also prevent people from touching the screw, thereby improving safety.

[0013] Optionally, a first cavity is provided in the first column, a second cavity is provided in the second column, a first slide groove is provided on the side of the first column facing the frame, a second slide groove is provided on the side of the second column facing the frame, a limit block is provided on the side of the frame facing the first column, the limit block extends into the first cavity, and a slider is provided on the side of the frame facing the second column, and the slider extends into the second cavity; a screw rod extending in a vertical direction is provided in the first cavity, the screw rod passes through the limit block, and the screw rod and the limit block are threadedly connected, and a light rod extending in a vertical direction is provided in the second cavity, the light rod passes through the slider, and the light rod and the slider are slidably connected.

The cooperation between the slider and the polished rod can improve the stability of the frame movement process and prevent the frame from tilting.

[0015] Optionally, the first slide groove and the second slide groove are arranged at the same height, and the height of the frame is greater than the height of the first slide groove.

[0016] By adopting the above technical solution, when the frame is in a high position, the frame can completely cover the first slide groove and the second slide groove, thereby ensuring that external debris such as rainwater will not enter the first cavity or the second cavity through the first slide groove or the second slide groove, thereby ensuring that the frame can move up and down reliably.

[0017] Optionally, the outer wall of the limit block fits with the inner wall of the first cavity, the limit block is arranged on the upper part of one side of the frame, the outer wall of the slider fits with the inner wall of the second cavity, and the slider is arranged on the upper part of the other side of the frame.

[0018] By adopting the above technical solution, it is ensured that when the screw rod rotates, the limit block can reliably slide in the first cavity and the sliding block can reliably slide in the second cavity.

[0020] By adopting the above technical solution, when the height of the frame needs to be adjusted, the hexagonal tube is rotated with a wrench, so that the vertical bevel gear and the horizontal bevel gear are driven to rotate through the hexagonal tube, thereby realizing the driving effect on the screw rod. During the descent of the frame, the slider will form a compression effect on the spring, so that the spring can support the slider, thereby making the descent of the frame smoother.

[0021] Optionally, a sealing ring is provided on both sides of the frame, one sealing ring is arranged on the outer side of the first slide groove, and the other sealing ring is arranged on the outer side of the second slide groove.

[0022] By adopting the above technical solution, under the sealing effect of the sealing ring, external debris will not enter the first cavity or the second cavity through the first sliding groove or the second sliding groove.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. By arranging the first column and the second column in the foundation pit and covering the foundation pit with a cover plate, the screw and the nut are hidden. On the one hand, the aging of the screw and the nut can be delayed to ensure the locking effect of the screw and the nut on the bottom plate after the screw and the nut are matched. On the other hand, it can prevent people from stepping on or hitting the screw, thereby improving safety.

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] Figure 1 This is a reference diagram of the application in use. Figure 1 A mobile display board along the street in a city includes a first column 1, a second column 2 and a frame 3. Two foundation pits 4 are provided on the ground. The first column 1 is provided in one foundation pit 4, and the second column 2 is provided in another foundation pit 4. The frame 3 is provided between the first column 1 and the second column 2, and display materials are detachably mounted on the frame 3.

[0037] Figure 2 is a schematic diagram of the internal structure of this application, Figure 3 yes Figure 2 A schematic diagram of the enlarged structure at A in the middle. Figure 2 and Figure 3 A fixing plate 41 is embedded in the foundation pit 4 (i.e., the fixing plate 41 is fixed in the foundation pit 4 by embedding concrete), and a bottom plate 5 is fixed at the bottom of the first column 1 and the bottom of the second column 2. When the first column 1 and the second column 2 are placed in the foundation pit 4, the fixing plate 41 and the bottom plate 5 are in a mutually fitting state. A plurality of threaded holes 411 are provided on the fixing plate 41, and a plurality of through holes 50 are provided on the bottom plate 5. One through hole 50 is correspondingly arranged with one threaded hole 411 and is in a coaxial state. At the same time, a plurality of through holes 50 on one bottom plate 5 are dispersedly arranged around the first column 1, and a plurality of through holes 50 on another bottom plate 5 are dispersedly arranged around the second column 2. A screw 412 (i.e., a rod body with threads on the surface) is inserted between the fixing plate 41 and the bottom plate 5. One end of the screw 412 is adaptively screwed in the threaded hole 411, and the other end of the screw 412 is inserted in the through hole 50 and extends toward the opening of the foundation pit 4. A nut 413 is adaptively screwed on the screw rod 412, and the nut 413 is located on the top of the base plate 5. When the screw rod 412 is rotated into place, the nut 413 is rotated again to fix the base plate 5, thereby ensuring that the first column 1 and the second column 2 can be reliably fixed in the foundation pit 4.

[0038] The outer walls of the first column 1 and the second column 2 are both sleeved with a cover plate 6, which can slide on the first column 1 and the second column 2. When installing the first column 1 or the second column 2, the cover plate 6 can be slid to a higher position first, so as to leave enough operating space for the rotation of the screw rod 412 and the nut 413, thereby improving the installation speed of the first column 1 or the second column 2. After the nut 413 is locked, the first column 1 or the second column 2 is in a vertical state, and the cover plate 6 can be slid downward at this time, so that the cover plate 6 can be sealed at the opening of the foundation pit 4. By adjusting the screwing depth of the screw rod 412 in the threaded hole 411, the top height of the screw rod 412 can be adjusted. In this way, without affecting the locking effect of the screw rod 412 and the nut 413 on the bottom plate 5, the cover plate 6 can be supported by a plurality of screw rods 412, so that the top of the cover plate 6 can be flush with the top of the foundation pit 4. When the top plate of the cover plate 6 is flush with the top of the foundation pit 4, the outer wall of the cover plate 6 and the inner wall of the foundation pit 4 are also in a mutually fitting state, so that the sealing effect of the cover plate 6 on the foundation pit 4 can be improved, thereby effectively preventing external debris from entering the foundation pit 4, and effectively preventing personnel from easily touching the screw 412 and the nut 413, which significantly improves the safety performance. Further, a gasket can be placed in the threaded hole 411 to control the screw-in depth of the screw 412, so that it can be ensured that the screw 412 will not be displaced during the process of tightening the nut 413, thereby ensuring that the ends of the plurality of screws 412 can form a reliable support for the cover plate 6.

[0039] Figure 4 is a schematic perspective view of the frame. Figure 4 Combined with Figure 2 and Figure 3A first cavity 11 is provided on the inner side of the first column 1, a second cavity 21 is provided on the inner side of the second column 2, a first slide groove 12 communicating with the first cavity 11 is provided on the outer wall of the first column 1, and a second slide groove 22 communicating with the second cavity 21 is provided on the outer wall of the second column 2. The first slide groove 12 and the second slide groove 22 have the same shape, size and setting height. A limit block 31 is provided on the side of the frame 3 facing the first column 1, and a slider 32 is provided on the side of the frame 3 facing the second column 2. The limit block 31 extends to the inner side of the first cavity 11 through the first slide groove 12, and the outer wall of the limit block 31 is in contact with the inner wall of the first cavity 11. The slider 32 extends to the inner side of the second cavity 21 through the second slide groove 22, and the outer wall of the slider 32 is in contact with the inner wall of the second cavity 21. A screw rod 111 is provided in the first cavity 11, and a polished rod 211 is provided in the second cavity 21. Both the screw rod 111 and the polished rod 211 extend in the vertical direction. A pair of bearings 112 are provided in the first cavity 11. One bearing 112 is sleeved on the upper part of the screw rod 111, and the other bearing 112 is sleeved on the lower part of the screw rod 111. In this way, the screw rod 111 is reliably fixed in the first cavity 11 and can also rotate around its own axis. The polished rod 211 is supported in the second cavity 21, that is, the top of the polished rod 211 is connected to the top of the second cavity 21, and the bottom of the polished rod 211 is connected to the bottom of the second cavity 21. The limit block 31 is sleeved on the outside of the screw rod 111, and the limit block 31 and the screw rod 111 are threadedly connected. The slider 32 is sleeved on the outside of the polished rod 211, and the slider 32 and the polished rod 211 are slidably connected.

[0040] See also Figure 2 A transverse bevel gear 113 is provided at the lower part of the screw rod 111, a through hole 13 communicating with the first cavity 11 is provided at the lower part of the first column 1, an inner hexagonal tube 114 is inserted into the through hole 13, one end of the inner hexagonal tube 114 is flush with the outer wall of the first column 1, and the other end of the inner hexagonal tube 114 is located in the first cavity 11 and is provided with a vertical bevel gear 115, and the vertical bevel gear 115 and the transverse bevel gear 113 are in a state of mutual meshing. When it is necessary to replace the display materials in the frame 3, the hexagonal tube 114 can be rotated with a wrench, so that the vertical bevel gear 115 and the horizontal bevel gear 113 are driven, so that the screw rod 111 can rotate in the first cavity 11. Since the limit block 31 and the screw rod 111 are in a threaded connection state, and the limit block 31 cannot rotate under the restriction of the first slide groove 12, the rotation of the screw rod 111 can drive the limit block 31 to slide up and down in the first cavity 11, and the frame 3 can be moved downward, so that the display materials in the frame 3 can be replaced quickly and safely without using a ladder.

[0041] See also Figure 2 and Figure 4A spring 212 is sleeved on the light rod 211. The spring 212 is located at the bottom of the slider 32 and supports the slider 32. When the frame 3 is in a descending state, the spring 212 will be compressed by the slider 32, thereby supporting the slider 32. In this way, the stability of the frame 3 during the descending process can be effectively improved to prevent the frame 3 from tilting. A sealing ring 33 is provided on both sides of the frame 3, one sealing ring 33 is arranged on the outer side of the first slide groove 12, and the other sealing ring 33 is arranged on the outer side of the second slide groove 22. At the same time, the height of the frame 3 is greater than the height of the first slide groove 12. At the same time, the limit block 31 is arranged on the upper part of one side of the frame 3, and the slider 32 is arranged on the upper part of the other side of the frame 3. In this way, when the display materials on the frame 3 are installed and the frame 3 is moved to a high place, the end of the frame 3 will form a sealing effect on the first slide groove 12 and the second slide groove 22. At the same time, under the sealing effect of the sealing ring 33, external debris such as rainwater is effectively prevented from entering the first cavity 11 or the second cavity 21, thereby ensuring that the driving effect of the screw rod 111 and the limit block 31 on the frame 3 is reliable, and the supporting effect of the light rod 211 and the slider 32 on the frame 3 is reliable.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
