Description

Technical Field

[0001] This utility model relates to the field of signage technology, specifically to a city signage with adjustable height. Background Technology

[0002] As an important component of urban public facilities, urban signs play a crucial role in guiding directions, conveying information, and regulating order. They are widely distributed in places such as road intersections, parks and scenic spots, commercial districts, and transportation hubs. The rationality of their placement and the accessibility of information directly affect the efficiency of citizens' travel and the level of urban management. Most signs are made of concrete or are rigidly fixed with bolts, and once the height is determined, it cannot be adjusted.

[0003] To address the aforementioned deficiencies, existing technology (Chinese patent No. CN220796159U, published on April 16, 2024) provides height-adjustable signs. A sliding rod and a rotating cylinder have a corresponding number of holes symmetrically arranged on both sides of their surfaces. Construction workers rotate the rotating cylinder, causing it to spiral upwards along the adjusting screw. Simultaneously, this pushes the support rod and mounting frame, which are fixedly connected to it, upwards. At the same time, the protective shell rotatably connected to the mounting frame and the warning sign embedded within it are also pushed upwards and adjusted to a suitable height. Then, the holes on the surfaces of the sliding rod and rotating cylinder are aligned, and the insertion rod is pressed, allowing it to pass through the limiting post and insert into the rotating cylinder and sliding rod, thus fixing them in place and preventing the rotating cylinder from slipping off the sliding rod due to its weight. This also simultaneously secures the entire sign.

[0004] When the height of the above-mentioned solution is adjusted during use, the center of gravity of the sign will change as the height increases. When affected by external factors, the sign is prone to tipping over due to insufficient stability of the bottom support, which will affect the use of the city sign. Utility Model Content

[0005] The purpose of this invention is to overcome the problem in the above-mentioned background technology that, during use, when the height is adjusted, the center of gravity of the sign changes accordingly, and when affected by external factors, it is prone to tipping over due to insufficient stability of the bottom support, thus affecting the use of the city sign.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a city sign that is easy to adjust in height, including a base, a sleeve integrally installed on the top of the base, a column slidably connected to the middle of the top surface of the sleeve, and the sign body of the column; The sleeve has a first screw rotatably connected to the middle of its inner side, and a column is threadedly connected to the outer side of the first screw. Support components for maintaining lateral stability are provided between the two sides of the sleeve and the base. The bottom of the base has an auxiliary component to expand the support area and maintain the stability of the bottom surface.

[0007] Furthermore, a motor is installed in the center of the bottom surface of the base, and the output end of the motor is connected to a first screw. The column drives the sign body through the first screw to form a height adjustment structure. Both the sleeve and the column are set as rectangular structures.

[0008] Furthermore, the support assembly includes vertical grooves symmetrically opened on the left and right sides of the sleeve, and a second screw is rotatably connected in the vertical groove. A torsion spring and a pull rope are installed on the top of the second screw.

[0009] Furthermore, the top of the pull rope is fixedly connected to the bottom of the sign body, the second screw forms a rotating structure through a torsion spring and the pull rope, and a slider is threadedly connected to the outer side of the second screw, the slider forming a vertical sliding structure through the second screw.

[0010] Furthermore, a support rod is hinged to the outer side of the slider, and a second slider is hinged to the bottom of the support rod. The second slider is slidably connected to a horizontal groove symmetrically opened at the top of the base. The support rod, the base, and the sleeve form a triangular support area.

[0011] Furthermore, the auxiliary component includes a circular plate fixed to the outer side of the bottom of the first screw. The bottom of the circular plate is provided with an arc-shaped guide groove at equal angles. A circular rod is slidably connected in the guide groove. The bottom of the circular rod is slidably connected to a rectangular limiting groove. The limiting groove is opened through the bottom of the base.

[0012] Furthermore, the round rod forms an opening and closing sliding structure through the guide groove and the limiting groove, and an auxiliary plate is fixed at the bottom of the round rod. The auxiliary plate adjusts the support area of ​​the base by telescopic sliding.

[0013] Compared with the prior art, the beneficial effects of this utility model are: when the height of the city sign is adjusted by the screw during use, the support rods on both sides will move accordingly, thereby increasing the stability of the lateral support. At the same time, the auxiliary plate at the bottom will also extend synchronously, increasing the support area between the overall sign and the bottom surface, thus maintaining the stability of the sign at all times during height adjustment.

[0014] Furthermore, the motor drives the first screw to rotate, and the column threadedly connected to the first screw slides vertically along the inner wall of the sleeve, thereby driving the top sign body to rise and fall, realizing height adjustment. The rectangular structure of the sleeve and column can effectively prevent rotational deviation during the adjustment process, ensuring that the sign body always remains horizontal.

[0015] Furthermore, when the sign body rises, its bottom pulls the pull rope, which drives the second screw in the vertical groove on both sides of the sleeve to rotate against the elastic force of the torsion spring. When the second screw rotates, the first slider connected by the outer thread slides upward along the vertical groove, pushing the hinged support rod to unfold. The second slider at the bottom of the support rod slides outward along the horizontal groove at the top of the base, so that the support rod, the base, and the sleeve form a stable triangular support area. The higher the height, the gentler the support angle and the stronger the lateral stability.

[0016] Furthermore, when the first screw rotates, the circular plate on its outer bottom rotates along with it. The arc-shaped guide groove at the bottom of the circular plate pushes the circular rod embedded in it to move. The circular rod is restricted by the rectangular limiting groove at the bottom of the base and slides outward along the limiting groove, causing the auxiliary plate at the bottom to unfold synchronously, increasing the contact area between the base and the ground. When the sign body is raised, the expansion range of the auxiliary plate increases, enhancing stability. Attached Figure Description

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0021] Example 1: Please refer to Figure 1 - Figure 2 This utility model provides the following technical solution: a city signboard with adjustable height, including a base 1, a sleeve 2 integrally installed on the top of the base 1, a column 3 slidably connected to the middle of the top surface of the sleeve 2, a signboard body 4 on the column 3, a first screw 6 rotatably connected to the middle of the inner side of the sleeve 2, a column 3 threadedly connected to the outer side of the first screw 6, support components for maintaining lateral stability provided between the two sides of the sleeve 2 and the base 1, and auxiliary components for expanding the support area and maintaining bottom stability provided at the bottom of the base 1, and a height adjustment mechanism for the signboard, wherein a motor 5 is installed in the middle of the bottom surface of the base 1, the output end of the motor 5 is connected to the first screw 6, and the column 3 drives the signboard body 4 through the first screw 6 to form a height adjustment structure, and both the sleeve 2 and the column 3 are set as rectangular structures.

[0022] In use, the sleeve 2 at the top of the base 1 and the column 3 adopt a rectangular structure to ensure guiding stability during lifting. The motor 5 on the bottom of the base 1 drives the first screw 6 to rotate, and the column 3, which is threaded to the first screw 6, slides vertically along the inner wall of the sleeve 2, thereby driving the sign body 4 at the top to rise and fall, realizing height adjustment. The rectangular structure of the sleeve 2 and the column 3 can effectively prevent rotational deviation during the adjustment process, ensuring that the sign body 4 always remains horizontal and avoiding the impact of angular deviation on information reading. Through the cooperation of the support components and auxiliary components, a dynamic balance between flexible height adjustment and overall stability is achieved. The core lies in using a mechanical transmission linkage support structure to ensure that the sign remains stable when the height changes. This not only solves the problem of insufficient stability when the height of traditional signs is fixed or adjusted, but also takes into account spatial adaptability, making it suitable for various urban public scenarios. Example

[0023] Based on Embodiment 1, a stability enhancement mechanism for the lateral support assembly is also disclosed, the specific structure of which is as follows: The support assembly includes vertical grooves 7 symmetrically opened on the left and right sides of the sleeve 2. A second screw 8 is rotatably connected in the vertical grooves 7. A torsion spring 9 and a pull rope 10 are installed on the top of the second screw 8. The top of the pull rope 10 is fixedly connected to the bottom of the sign body 4. The second screw 8 forms a rotating structure through the torsion spring 9 and the pull rope 10. A first slider 11 is threadedly connected to the outer side of the second screw 8. The first slider 11 forms a vertical sliding structure through the second screw 8. A support rod 12 is hinged to the outer side of the first slider 11. A second slider 13 is hinged to the bottom of the support rod 12. The second slider 13 is slidably connected in a horizontal groove 14 symmetrically opened on the top of the base 1. The support rod 12, the base 1, and the sleeve 2 form a triangular support area.

[0024] During use, when the sign body 4 rises, its bottom pulls the pull rope 10. The pull rope 10 drives the second screw 8 in the vertical grooves 7 on both sides of the sleeve 2 to rotate against the elastic force of the torsion spring 9. When the second screw 8 rotates, the first slider 11 connected by the outer thread slides upward along the vertical groove 7, pushing the hinged support rod 12 to unfold. The second slider 13 at the bottom of the support rod 12 slides outward along the horizontal groove 14 at the top of the base 1, so that the support rod 12, the base 1, and the sleeve 2 form a stable triangular support area, dispersing the lateral force on the sign body 4. When the sign body 4 falls, the pull force of the pull rope 10 weakens, and the second screw 8 rotates in the opposite direction under the action of the torsion spring 9, driving the first slider 11 to slide down. The support rod 12 then retracts, avoiding excessive space occupation. The dynamic adjustment of the triangular support structure can automatically adapt the support range according to the height of the sign body 4. The higher the height, the gentler the support angle and the stronger the lateral stability. Example

[0025] Based on Embodiment 2, a bottom support area expansion mechanism for the auxiliary component is also disclosed. Its specific structure is as follows: The auxiliary component includes a circular plate 15 fixed to the outer side of the bottom of the first screw 6. An arc-shaped guide groove 16 is opened at the bottom of the circular plate 15 at equal angles. A circular rod 17 is slidably connected in the guide groove 16. The bottom of the circular rod 17 is slidably connected to a rectangular limiting groove 18. The limiting groove 18 is opened through the bottom of the base 1. The circular rod 17 forms an opening and closing sliding structure through the guide groove 16 and the limiting groove 18. An auxiliary plate 19 is fixed to the bottom of the circular rod 17. The auxiliary plate 19 adjusts the support area of ​​the base 1 by telescopic sliding.

[0026] During use, when the first screw 6 rotates, the circular plate 15 on its outer bottom rotates along with it. The arc-shaped guide groove 16 at the bottom of the circular plate 15 pushes the circular rod 17 embedded therein to move. The circular rod 17 is restricted by the rectangular limiting groove 18 at the bottom of the base and slides outward along the limiting groove 18, causing the auxiliary plate 19 at the bottom to unfold synchronously, increasing the contact area between the base 1 and the ground. When the sign body 4 is raised, the expansion range of the auxiliary plate 19 increases, reducing the risk of center of gravity shift by expanding the support base 1. When the height is reduced, the circular rod 17 returns to its original position with the guide groove 16, and the auxiliary plate 19 retracts, reducing the occupation of ground space. The expansion design of the auxiliary plate 19 is linked with the height adjustment, improving the overall anti-tipping ability from the bottom.
