Technical Field

[0001] The utility model relates to the technical field of notice boards, and in particular to an adjustable hidden road-blocking notice board. Background Art

[0002] With the continuous advancement of urbanization, road construction is also accelerating. In order to ensure the safety of pedestrians and vehicles during road construction, maintenance or emergencies, road signs are often needed to remind and guide pedestrians and vehicles. Road signs can remind people that the road ahead is blocked, thereby avoiding accidents. The use of road signs can attract people's attention and warn people of specific information, thereby instructing people to stay away as soon as possible and curbing the harm.

[0003] The current road blocking signs are supported by brackets, the signs are connected to the brackets, and then relevant notices are posted on the signs. The road blocking signs are then placed at the locations where road blocking is required. However, since the signs cannot be folded up and hidden, they are prone to cause visual interference when not in use, and are easily affected by external factors such as bad weather and pollutants, resulting in a shortened service life. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned technical deficiencies and provide an adjustable hidden road sign to solve the technical problems in the field of sign technology that when the sign is not in use, it is easy to cause visual interference and is easily affected by external factors such as bad weather and pollutants, resulting in a shortened service life.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0016] See also Figure 1 , Figure 2 , Figure 3 This embodiment provides an adjustable hidden road sign, including:

[0017] Furthermore, the two ends of the hidden plate 4 are fixedly connected with connecting blocks 2, and the connecting blocks 2 are adjustably rotatably connected to the two ends of the support frame 1. Ears are provided on both sides of the hidden plate, and the ears are located at the upper end of the connecting blocks 2. A guide rod is provided in the ear, one end of the guide rod is inserted into the ear, and the other end of the guide rod is fixedly connected to the lifting frame 5; a display 6 is provided in the lifting frame 5, and the guide rod is annularly sleeved with a first elastic element 8, one end of the first elastic element 8 abuts against the upper end of the ear, and the other end of the first elastic element 8 abuts against the display 6.

[0018] Specifically, when the display 6 is working, under the elastic force of the first elastic element 8, the display 6 is raised to the top of the hidden plate 4; when the display 6 does not need to work, in order to solve the technical problem that "the display 6 is prone to cause visual interference and is easily affected by external factors such as bad weather and pollutants, resulting in a shortened service life", it is necessary to press down the display 6, squeeze the first elastic element, and store the display 6 into the hidden plate 4.

[0019] Preferably, the first elastic element 8 is selected as a spring. As a common elastic element, the spring is widely used in industry and daily life. Its advantages mainly include: 1. Scalability: the spring can be deformed when subjected to external force, and can return to its original state after the external force disappears. This reversible deformation characteristic makes it very useful in many occasions that require buffering and shock absorption; 2. Force transmission: the spring can be used to transmit and adjust force; 3. Adaptability: the spring can be designed and manufactured in different shapes and sizes as needed to adapt to different application scenarios; 4. Durability: high-quality springs have a long service life under normal use conditions and low maintenance costs; 5. Stability: the mechanical properties of the spring are relatively stable and can provide a stable reaction force within a certain range; 6. Economy: compared with other mechanical structures, springs are usually manufactured at a lower cost and are suitable for large-scale production; 7. Easy installation: the installation of the spring is usually simple and does not require complex auxiliary equipment.

[0020] Furthermore, the support frame 1 includes a supporting part and a connecting part, both ends of the connecting part are fixedly connected to the two sides of the supporting part, the cross-section of the supporting part is triangular, and a rotating hole is opened at the top of the supporting part. One end of the connecting block 2 is inserted into the rotating hole and is rotatably connected to the supporting part.

[0021] Furthermore, a limiting hole is provided at the upper end of the support portion, and the limiting hole is connected to the rotating hole. A limiting bolt 3 is threadedly connected to the limiting hole. When the hidden plate 4 needs to be rotated, the limiting bolt 3 is rotated so that the top end of the limiting bolt 3 is disengaged from the connecting block 2. When the hidden plate 4 needs to be fixed, the limiting bolt 3 is rotated so that the top end of the limiting bolt 3 abuts against the fixing block.

[0022] Preferably, a limiting groove is provided at one end of the connecting block 2 inserted into the rotating hole, and the limiting groove is along the length direction of the rotating hole. The limiting groove array is circumferentially arranged at the end of the connecting block 2 inserted into the rotating hole. When the hidden plate 4 needs to be limited, the limiting bolt 3 is rotated so that one end of the limiting bolt 3 abuts against the limiting groove to prevent the hidden plate 4 from rotating.

[0023] Specifically, according to the terrain of the road construction reminder area, when it is necessary to adjust the angle of the hidden plate 4, loosen the limit bolt 3 to drive the connecting block 2 to rotate on the support frame 1. After the adjustment, tighten the limit bolt 3 to fix the connecting block 2 so that the angle of the hidden plate 4 is fixed. When road construction requires intercepting passing vehicles, the road construction information is displayed on the display 6 to provide interception prompts for passing vehicles.

[0024] Furthermore, a fixing part 10 is provided on one side of the hidden plate 4, and a rotating claw 11 is rotatably connected inside the fixing part 10. A second elastic element 12 is provided between the rotating claw 11 and the fixing part 10, and one end of the second elastic element 12 abuts against one side of the hidden plate 4, and the other end of the second elastic element 12 abuts against the rotating claw 11.

[0025] Specifically, when the display 6 needs to be hidden in the hidden plate 4, the lifting frame 5 is pushed to slide downward into the hidden plate 4, driving the guide rod 7 to move downward, and the second elastic element 12 is squeezed and contracted, so that the second elastic element 12 recovers and drives the rotating claw 11 to rotate above the lifting frame 5, so that the rotating claw 11 limits the lifting frame 5, thereby hiding the signboard when not in use to avoid visual interference and prolong its service life. When the display 6 needs to be used, the rotating claw 11 on the fixing member 10 is rotated so that the rotating claw 11 is separated from the top of the lifting frame 5, so that the second elastic element 12 rebounds and the lifting frame 5 pops out, so that the display 6 can prompt road information.

[0026] Preferably, the second elastic element 12 is selected as a torsion spring, also known as a torsion spring, which is a spiral spring that generates a rotational moment under a certain torque. They are generally used in situations where torsional or rotational actions are required, such as return, torque limitation or torque reserve in mechanical devices. When one end of the torsion spring rotates relative to the other end, the spring material twists and stores elastic potential energy. When the torque disappears, the torsion spring uses the stored energy to drive the component back to its original position. Torsion springs are usually manufactured by winding a certain length of metal wire, and the shape of the metal wire can be round, square or other special shapes to meet different application requirements. It has the following advantages: 1. Energy storage: Like compression springs and extension springs, torsion springs can store energy and release it when needed to provide a stable rotational force; 2. Return function: torsion springs can restore rotating parts to their original position after releasing the torque to ensure the normal operation of the system; 3. Space efficiency: Due to its compact structure, torsion springs are particularly useful in space-constrained occasions, saving space and providing the necessary torque; 4. Durability: High-quality torsion springs can withstand millions of torsion cycles under the correct application conditions and have high durability; 5. Directionality: The torque of the torsion spring can work in two directions, clockwise and counterclockwise, making it suitable for bidirectional rotation applications; 6. Easy installation: torsion springs can usually be installed directly to rotating parts without the need for complicated installation tools or procedures; 7. Low maintenance cost: Once the torsion spring is installed in place, it usually does not require additional maintenance, and its durability and stability reduce maintenance costs.

[0027] Furthermore, a hidden groove is opened in the hidden plate 4 for hiding the display 6, and a rain shield 9 is provided at the upper end of the display screen. When the first elastic element 8 is in the original extended state, the display 6 is located at the upper end of the hidden groove, and when the first elastic element 8 is in the compressed state, the display 6 is located in the hidden groove.

[0028] Specifically, the rain shield 9 is used to block rainwater to prevent the display 6 from malfunctioning due to water ingress.

[0029] Working principle: When using the adjustable hidden road blocking sign provided by the utility model, first, place the support frame 1 in the road construction reminder area, then loosen the limit bolt 3, and rotate and adjust the angle of the hidden plate 4 according to the terrain of the road construction reminder area to drive the connecting block 2 to rotate on the support frame 1. After adjustment, tighten the limit bolt 3 to fix the connecting block 2 so that the angle of the hidden plate 4 is fixed.

[0030] When the road construction needs to intercept the passing vehicles, the road construction information is displayed on the display 6 to intercept the passing vehicles. The rain shield 9 is used to block rainwater to prevent the display 6 from malfunctioning due to water ingress. When the display 6 is not needed, the lifting frame 5 is pushed to slide downward into the hidden plate 4, driving the guide rod 7 to move downward, and the first elastic element 8 spring is squeezed and contracted, so that the second elastic element 12 recovers and drives the rotating claw 11 to rotate above the lifting frame 5, so that the rotating claw 11 limits the lifting frame 5, thereby hiding the billboard when not in use to avoid visual interference and prolong its service life. When the display 6 needs to be used, the rotating claw 11 on the fixing member 10 is rotated to disengage the rotating claw 11 from the lifting frame 5, so that the first elastic element 8 rebounds to make the lifting frame 5 pop out, so that the display 6 can prompt road information.

[0031] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
