Description

Technical Field

[0001] This utility model relates to the field of anti-glare panel technology, and in particular to an anti-glare panel with variable height. Background Technology

[0002] Currently, anti-glare panels are installed on the median strip or guardrails of roads to prevent glare from oncoming vehicles' headlights shining on each other and endangering driving safety. The main function of the anti-glare panels is to block the main beam of the headlights of vehicles on both lanes, avoiding interference with drivers' driving behavior and thus improving driving safety.

[0003] In the prior art, a variable-height anti-glare panel is disclosed in Chinese utility model patent with authorization announcement number CN203498767U. This patent adopts a multi-segment splicing form, with each segment having a splicing interface and splicing screw holes on the upper part. The panels are fixed together using bolts, with the base panel connected to the fixing facility. The spliced ​​panels are aligned in direction, and the screw holes are aligned and tightened, fixing the panel height. The number of splicing segments can be selected according to different design height requirements. The height of the anti-glare panel can be easily adjusted according to changes in road slope and length without significantly increasing the amount of template used. While the aforementioned patent allows multiple anti-glare panels to be spliced ​​using nuts and bolts, this operation is too cumbersome, especially in scenarios where a large number of anti-glare panels are needed on highways. The cumbersome operation greatly reduces the efficiency of height adjustment on highways. Furthermore, for temporary construction scenarios, the installation of anti-glare panels is difficult, and it is hard to quickly change the installation method based on the difference between long-term burial and temporary construction.

[0004] Therefore, this utility model provides a variable height anti-glare panel. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a variable-height anti-glare panel, which solves the problems of cumbersome assembly and high workload associated with existing height-adjustable anti-glare panels.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A variable-height anti-glare panel includes a support rod, with several anti-glare panels connected to the top of the support rod. Adjacent anti-glare panels are detachably connected by a connecting assembly. A counterweight structure is provided on the support rod, and an embedded structure is provided at the bottom of the support rod.

[0008] In this design, several anti-glare panels on the support rod are connected by a connecting assembly. The overall height can be adjusted by adding or removing the number of anti-glare panels, making the adjustment simple. The buried structure is used to fix the entire device underground.

[0009] Furthermore, the connecting assembly includes a square tube and a connecting block, which are fixedly connected to the top and bottom of two adjacent anti-glare panels, respectively; the connecting block is inserted into the inside of the square tube; and the sides of both the square tube and the connecting block are laterally provided with through-holes, into which limit rods are inserted.

[0010] In this solution, when height adjustment is required, the connecting block at the bottom of the upper anti-glare panel is inserted into the inner cavity of the square tube at the top of the lower anti-glare panel. The matching cross-section of the square tube and the connecting block ensures vertical alignment. Then, the limiting rod is passed through the limiting hole aligned with the side of the square tube and the connecting block to connect the connecting block and the square tube. This allows for the rapid splicing and height locking of multiple anti-glare panels without the need for tools.

[0011] Furthermore, two limiting frames are connected to both sides of the square tube, and each limiting frame has an insertion hole; the limiting rod also has an insertion hole at a position corresponding to the insertion hole of the limiting frame; and elastic pins are inserted into the insertion holes of the limiting frame and the limiting rod.

[0012] In this solution, the two ends of the elastic pin are pressed inward to make it elastically contract, and then inserted into the insertion holes of the limiting frame and the limiting rod. After being released, the elastic pin returns to its original shape due to the elasticity of the metal, and the two ends open and clamp the inner wall of the insertion hole, thus completing the fixation of the limiting rod. Multi-segment anti-glare panels can be quickly spliced ​​and height locked without tools, preventing the limiting rod from sliding arbitrarily in the limiting hole and ensuring the stability after assembly.

[0013] Furthermore, the elastic pin is a U-shaped elastic metal strip, and the two ends of the elastic metal strip are inserted into the insertion holes of the limiting rod through elastic deformation to fix the limiting rod, the square tube and the connecting block.

[0014] In this solution, the structural characteristics of the U-shaped elastic metal strip cause it to elastically contract when pressed and inserted, and automatically open and clamp the inner wall of the insertion hole after release. The installation and removal of the limit rod can be completed without the aid of tools, which significantly simplifies the splicing operation and ensures the connection stability between the square tube and the connecting block.

[0015] Furthermore, a square tube is connected to the top of the support rod, and the square tube is connected to the connecting block at the bottom of the adjacent anti-glare panel.

[0016] Furthermore, the cross-sectional shape of the connecting block matches the cross-sectional shape of the inner cavity of the square tube, and the limiting rod is set perpendicular to the axial direction of the square tube.

[0017] Furthermore, the counterweight structure includes a counterweight base sleeved on the surface of the support rod, and the counterweight base is hollow inside; the surface of the counterweight base has a threaded inlet, and a sealing cap is threaded onto the threaded inlet.

[0018] In this solution, materials such as sand or water can be easily injected through the threaded inlet to adjust the counterweight and adapt to the stability requirements of different ground conditions. In practice, the operator unscrews the sealing cap and injects the counterweight into the filling cavity inside the counterweight base through the threaded inlet. Then, the sealing cap is tightened to prevent leakage. The weight of the counterweight base is transferred to the ground through the support rod, achieving stable placement in temporary construction scenarios. At the same time, the filling amount can be flexibly adjusted according to actual needs.

[0019] Furthermore, the counterweight base and the support rod are fitted with a clearance, and the bottom of the counterweight base is provided with an annular limiting flange.

[0020] Furthermore, the embedded structure includes an embedded rod, the top of which is inserted into a sleeve hole at the bottom of a support rod; a support base is connected to the bottom of the embedded rod; positioning holes are provided at both ends of the embedded rod, and through holes matching the positioning holes are provided on the side of the support rod, with positioning rods passing through the positioning holes and through holes.

[0021] In this solution, the embedded rod is a telescopic structure. For long-term fixed applications, the embedded rod is completely pulled out of the sleeve hole at the bottom of the support rod. The embedded rod is adjusted so that its top positioning hole aligns with the through hole on the side of the support rod. A positioning rod is inserted through both, creating an extended embedded state. The bottom end of the embedded rod is then buried in the ground. For temporary construction applications, the embedded rod is completely pushed into the sleeve hole of the support rod, aligning the positioning hole at the bottom of the embedded rod with the through hole on the side of the support rod. A positioning rod is inserted to secure the embedded rod in its retracted state. At this point, the counterweight base is moved down along the surface of the support rod, contacting the ground through its bottom annular limiting flange. The sealing cap is opened, and sand or water is injected into the filling cavity of the counterweight base through the threaded inlet to increase the overall counterweight. Finally, the sealing cap is tightened, allowing the anti-glare panel to be directly and stably placed on the ground via the counterweight, eliminating the need for burial operations.

[0022] The beneficial effects of this utility model are:

[0023] The variable-height anti-glare panel provided by this utility model achieves rapid assembly and height adjustment of the anti-glare panel through the insertion and cooperation of square tubes and connecting blocks, combined with the elastic locking and fixing of the limiting rod through the limiting hole of the square tube and the connecting block and the elastic pin. The U-shaped elastic metal strip structure of the elastic pin is inserted into the insertion hole of the limiting rod through the elastic deformation of both ends, forming a limiting fixation without tool operation, which significantly improves the splicing efficiency of multi-segment anti-glare panels and solves the problem of cumbersome operation of traditional bolt splicing.

[0024] The variable-height anti-glare panel provided by this utility model achieves the extension or retraction of the buried rod by means of the telescopic cooperation between the bottom sleeve hole of the support rod and the buried rod, and by utilizing the alignment relationship between the positioning holes at both ends of the buried rod and the through hole of the support rod. In conjunction with the counterweight structure, the internal filling cavity of the counterweight base is filled with sand or water through the threaded inlet to increase the counterweight. This allows the same anti-glare panel to be fixed in the ground by the buried rod for long-term use, and to be placed directly on the ground by the counterweight base to meet temporary construction needs, thus improving the applicability of the installation scenarios.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The specific embodiments of the present invention are described below to facilitate understanding by those skilled in the art. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they fall within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0032] like Figure 1 As shown, this embodiment provides a variable height anti-glare panel, which solves the problem that the assembly of anti-glare panels using bolts, nuts and other connectors is too cumbersome. It is suitable for scenarios where a large number of anti-glare panels are needed on highways, and improves the efficiency of adjusting the height of anti-glare panels on highways. The variable height anti-glare panel specifically includes: a support rod 1, an anti-glare panel 3, a connecting component 2, an embedded structure 5 and a counterweight structure 4.

[0033] The top of the support rod 1 is connected to several anti-glare plates 3, and two adjacent anti-glare plates 3 are detachably connected by a connecting component 2. The overall height can be adjusted by adding or removing the number of anti-glare plates 3, and the adjustment is simple. The support rod 1 is equipped with a counterweight structure 4, and the bottom of the support rod 1 is equipped with a buried structure 5, which is buried underground to fix the overall device.

[0034] The connecting component 2 includes a square tube 21, a connecting block 22, and a limiting rod 23. The square tube 21 and the connecting block 22 are fixedly connected to the top and bottom of two adjacent anti-glare panels 3, respectively. The connecting block 22 is inserted into the inside of the square tube 21. Both the square tube 21 and the connecting block 22 have transverse limiting holes on their sides, and the limiting rod 23 is inserted into the limiting holes. When height adjustment is required, the connecting block 22 at the bottom of the upper anti-glare panel 3 is inserted into the inner cavity of the square tube 21 at the top of the lower anti-glare panel 3. The matching cross-sections of the square tube 21 and the connecting block 22 ensure vertical alignment. Then, the limiting rod 23 is passed through the limiting holes aligned on the sides of the square tube 21 and the connecting block 22 to connect the square tube 21 and the connecting block 22, achieving fast assembly.

[0035] Two limiting frames are connected to both sides of the square tube 21, and each limiting frame has an insertion hole. The limiting rod 23 also has an insertion hole corresponding to the insertion holes of the limiting frames. Elastic pins 24 are inserted into the insertion holes of the limiting frames and the limiting rod 23. During assembly, the two ends of the elastic pins 24 are pressed inward to retract their elasticity, and then inserted into the insertion holes of the limiting frames and the limiting rod 23. After releasing, the elastic pins 24 return to their original shape due to the elasticity of the metal, and the two ends open and clamp onto the inner wall of the insertion hole, thus fixing the limiting rod 23. This allows for quick splicing and height locking of multiple anti-glare panels 3 without tools, preventing the limiting rod 23 from sliding arbitrarily within the limiting holes and ensuring stability after assembly.

[0036] The elastic pin 24 is a U-shaped elastic metal strip. Both ends of the elastic metal strip are inserted into the insertion holes of the limiting rod 23 through elastic deformation, thus fixing the limiting rod 23, the square tube 21, and the connecting block 22. The structural characteristics of the U-shaped elastic metal strip allow it to elastically contract when pressed and automatically open and clamp the inner wall of the insertion hole after release. This allows for the installation and removal of the limiting rod 23 without the need for tools, significantly simplifying the splicing operation and ensuring the connection stability between the square tube 21 and the connecting block 22.

[0037] A square tube 21 is connected to the top of the support rod 1, and the square tube 21 is connected to the connecting block 22 at the bottom of the adjacent anti-glare plate 3.

[0038] The cross-sectional shape of the connecting block 22 matches the cross-sectional shape of the inner cavity of the square tube 21, and the limiting rod 23 is set perpendicular to the axial direction of the square tube 21.

[0039] The counterweight structure 4 includes a counterweight base 41 sleeved on the surface of the support rod 1. The counterweight base 41 is hollow inside. A threaded inlet is provided on the surface of the counterweight base 41, and a sealing cap 42 is threaded onto the threaded inlet. A filling cavity is formed inside the counterweight base 41. Materials such as sand or water can be easily injected through the threaded inlet to adjust the counterweight and adapt to the stability requirements of different ground conditions. In practice, the operator unscrews the sealing cap 42 and injects the counterweight into the filling cavity inside the counterweight base 41 through the threaded inlet. Then, the sealing cap 42 is tightened to prevent leakage. The weight of the counterweight base 41 is transferred to the ground through the support rod 1, achieving stable placement in temporary construction scenarios. At the same time, the filling amount can be flexibly adjusted according to actual needs.

[0040] The counterweight base 41 and the support rod 1 are fitted with a clearance, and the bottom of the counterweight base 41 is provided with an annular limiting flange.

[0041] The embedded structure 5 includes an embedded rod 51 and a positioning rod 54; the top of the embedded rod 51 is inserted into the sleeve hole at the bottom of the support rod 1; the bottom of the embedded rod 51 is connected to a support base; positioning holes 52 are opened at both ends of the embedded rod 51, and through holes 53 matching the positioning holes 52 are opened on the side of the support rod 1, and positioning rod 54 is inserted inside the positioning holes 52 and through holes 53.

[0042] The embedded rod 51 is a telescopic structure. When used in long-term fixed scenarios, the embedded rod 51 is completely pulled out from the sleeve hole at the bottom of the support rod 1. The embedded rod 51 is adjusted so that its top positioning hole 52 is aligned with the through hole 53 on the side of the support rod 1. The positioning rod 54 is inserted through both to form an extended embedded state. Then, the bottom end of the embedded rod 51 is buried in the ground. When used in temporary construction scenarios, the embedded rod 51 is completely pushed into the sleeve hole of the support rod 1 so that the positioning hole 52 at the bottom of the embedded rod 51 is aligned with the through hole 53 on the side of the support rod 1. The positioning rod 54 is inserted to fix the embedded rod 51 in its retracted state. At this time, the counterweight base 41 is moved down along the surface of the support rod 1 and contacts the ground through its bottom annular limiting flange. The sealing cover 42 is opened and sand or water is injected into the filling cavity of the counterweight base 41 through the threaded inlet to increase the overall counterweight. Finally, the sealing cover 42 is tightened so that the anti-glare plate 3 is directly and stably placed on the ground by the counterweight without the need for burial operation.

[0043] The working principle of this embodiment is as follows:

[0044] The support rod 1 serves as the core load-bearing structure. Its top connecting component 2, through the insertion and connection of the square tube 21 and the connecting block 22, allows for height adjustment of the anti-glare panel 3. Specifically, when the connecting block 22 is inserted into the inner cavity of the square tube 21 of the adjacent anti-glare panel 3, the limiting rod 23 horizontally penetrates the limiting holes aligned with the sides of the square tube 21 and the connecting block 22. The U-shaped elastic metal strip of the elastic pin 24, with its elastic deformation at both ends, is inserted into the insertion hole of the limiting rod 23, forming a tool-free fixation and completing the rapid splicing of multiple anti-glare panels 3. The counterweight structure 4 on the surface of the support rod 1 is augmented by injecting sand or water through the threaded inlet of the counterweight base 41. Combined with the threaded locking of the sealing cap 42 and the clearance fit between the annular limiting flange at the bottom of the counterweight base 41 and the support rod 1, stable placement of the anti-glare panel 3 in temporary scenarios is achieved. The embedded structure 5 at the bottom of the support rod 1 is connected to the embedded rod 51 through the sleeve hole. The alignment relationship between the positioning holes 52 at both ends of the embedded rod 51 and the through holes 53 of the support rod 1 is used to switch between the embedded or stored state. After the positioning rod 54 is inserted, a long-term embedded fixed or temporary stored mode is formed. Finally, through the synergistic effect of the connecting component 2, the counterweight structure 4 and the embedded structure 5, the integrated function of adjustable height of the anti-glare plate 3, flexible installation method and improved scene adaptability is realized.
