Description

Technical Field

[0001] This utility model relates to a warning sign, specifically a warning sign for urban renewal, and belongs to the technical field of warning signs. Background Technology

[0002] Warning signs are warning signs placed at and around project sites. They are used when there are safety risks in urban renewal work such as demolition, infrastructure construction, and pipeline renovation, or when it is necessary to guide pedestrians and vehicles to detour or to inform them of relevant construction information.

[0003] The existing utility model with authorization announcement number CN220117058U discloses a safety warning mechanism for urban renewal. By setting up warning components, it can provide three types of warnings to passing pedestrians and vehicles: warning signs, warning lights, and warning tapes, thereby improving the warning effect. At the same time, by simply pulling the lever, the clamping and fixing of the warning sign can be released, and different types of warning signs can be replaced. It can be applied to safety warnings for various projects, thus improving practicality. By setting up a battery pack, it can provide power to the warning lights. In case of battery pack failure, a new battery pack can be replaced simply by lifting the baffle through the notch, which is quite convenient. By setting up an electric telescopic rod and universal wheels, the horizontal height of the mounting plate can be adjusted, and the mechanism can be moved to a designated location for use.

[0004] While the aforementioned technical solutions offer multiple warning effects and high mobility, they lack an external buffer and collision-resistant structure, making the supporting structure easily damaged by collisions with external vehicles. Therefore, this paper proposes a warning sign for urban renewal. Utility Model Content

[0005] This utility model proposes a warning sign for urban renewal to solve the problem that the lack of an outer buffer and anti-collision structure in the existing technology makes the supporting body easily damaged by collisions with external vehicles.

[0006] This utility model is achieved through the following technical solution: a warning sign for urban renewal, including a chassis, a column fixedly connected to the upper surface of the chassis, a plate fixedly connected to the top of the column, two transparent holding shells and four reflectors respectively provided on the outer side of the plate, and a buffer anti-collision mechanism provided above the chassis. The buffer anti-collision mechanism includes several identical support plates. Each support plate has a guide rod slidably connected inside. Each guide rod has a limit plate fixedly connected to one end near the support plate. Each guide rod has a buffer plate fixedly connected to one end away from the support plate. Each buffer plate has a buffer pad fixedly connected to one side away from the support plate. Each limit plate has a buffer washer fixedly connected to the outer surface of the guide rod along with one side near the support plate. Each guide rod has a buffer spring sleeved on its outer surface.

[0007] Specifically, the two transparent holding shells are fixedly connected to the front and back of the upright plate respectively on their adjacent sides, the reflector is fixedly connected to the outer surface of the upright plate on its adjacent side, the bottom surface of the support plate is fixedly connected to the upper surface of the chassis, the buffer washer is in contact with the outer surface of the support plate on its adjacent side, the two ends of the buffer spring are in contact with the outer surface of the support plate and the outer surface of the buffer plate respectively, the outer surface of the column is fixedly connected with an anti-slip sleeve, and the outer surface of the anti-slip sleeve is fixedly connected with an anti-slip protrusion.

[0008] Furthermore, the bottom surface of the chassis is fixedly connected to three connecting columns, and each connecting column is fixedly connected to a caster wheel at its bottom end.

[0009] The chassis has three threaded cylinders fixedly connected to its bottom surface, and each threaded cylinder has a threaded rod threadedly connected to its inner wall.

[0010] Preferably, a support plate is fixedly connected to the bottom end of each threaded rod, and an anti-slip pad is fixedly connected to the bottom surface of each support plate.

[0011] Furthermore, each of the buffer plates is fixedly connected to a limiting slide rod on one side near the support plate, and the outer surface of each limiting slide rod is slidably connected to the inside of the support plate.

[0012] This utility model provides a warning sign for urban renewal, which has the following beneficial effects: This type of warning sign for urban renewal utilizes a chassis, pillars, uprights, a transparent housing, reflectors, support plates, guide rods, buffer plates, limiting plates, buffer pads, buffer washers, and buffer springs in a coordinated manner. The transparent housing on the outside of the uprights can safely hold various warning slogans or construction information cards, facilitating replacement and protecting the content from damage by the external environment. Four reflectors can reflect light during low-light hours or in rainy weather, improving the visibility of the warning sign and alerting pedestrians and vehicles. In the buffer and anti-collision mechanism above the chassis, the support plate provides sliding support for the guide rod, and the limiting plate at one end of the guide rod prevents the guide rod from detaching from the support plate. The buffer plate at the other end, together with the buffer pads, can first contact the colliding object to initially reduce the impact force. The buffer washers and buffer springs on the outer surface of the guide rod further absorb the collision energy, preventing direct damage to the core support components such as the pillars and uprights from external collisions, extending the service life of the warning sign, ensuring the continuous effectiveness of the warning function during urban renewal construction, and avoiding the problem that the main support structure is easily damaged by collisions with external vehicles due to the lack of an external buffer and anti-collision structure.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] Please see Figures 1-5 This utility model embodiment provides a warning sign for urban renewal, including a chassis 1. A column 2 is fixedly connected to the upper surface of the chassis 1, and a vertical plate 3 is fixedly connected to the top of the column 2. Two transparent holding shells 4 and four reflectors 5 are respectively arranged on the outer side of the vertical plate 3. Different warning sign paper can be replaced inside the transparent holding shells 4. The reflectors 5 have good reflective warning effect at night. A buffer anti-collision mechanism 6 is arranged above the chassis 1. The buffer anti-collision mechanism 6 includes several identical support plates 601, and each support plate 601 has a sliding connection inside. The guide rod 602 has two transparent holding shells 4 with their sides close to each other, which are fixedly connected to the front and back of the upright plate 3 respectively. Each reflector 5 has its side close to the upright plate 3 fixedly connected to the outer surface of the upright plate 3. The bottom surface of each support plate 601 is fixedly connected to the upper surface of the chassis 1. The outer surface of the column 2 is fixedly connected to an anti-slip sleeve 7, and the outer surface of the anti-slip sleeve 7 is fixedly connected to an anti-slip protrusion 8. The anti-slip sleeve 7 and several anti-slip protrusions 8 on the outer surface of the column 2 make it convenient for staff to grip when moving or adjusting the warning sign, and prevent the warning sign from tipping over and being damaged due to slipping.

[0017] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 Each guide rod 602 is fixedly connected to a limiting plate 604 at the end near the support plate 601, and a buffer plate 603 is fixedly connected to the end of each guide rod 602 away from the support plate 601. Three connecting columns 9 are fixedly connected to the bottom surface of the chassis 1, and a caster wheel 10 is fixedly connected to the bottom end of each connecting column 9. The three connecting columns 9 and the three caster wheels 10 on the bottom surface of the chassis 1 enable the warning sign to move flexibly. Staff can easily move the warning sign to the required location according to the changes in the urban renewal construction area without the need for large equipment, saving manpower and time costs.

[0018] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5Each buffer plate 603 has a buffer pad 605 fixedly connected to the side away from the support plate 601. Three threaded cylinders 11 are fixedly connected to the bottom surface of the chassis 1. Each threaded cylinder 11 has a threaded rod 12 threadedly connected to its inner wall. The length of the three threaded cylinders 11 and three threaded rods 12 on the bottom surface of the chassis 1 can be adjusted by rotating the threaded rod 12, thereby adjusting the height of the support structure below the threaded rod 12.

[0019] Please refer to this carefully. Figure 1 , Figure 4 and Figure 5 Each limiting plate 604 has a buffer washer 606 fixedly connected to the outer surface of the guide rod 602 on one side near the support plate 601. Each buffer washer 606 has a contact side with the outer surface of the support plate 601 on one side. Each threaded rod 12 has a support plate 13 fixedly connected to its bottom end. Each support plate 13 has an anti-slip pad 14 fixedly connected to its bottom surface. The three support plates 13 at the bottom of the three threaded rods 12 increase the contact area with the ground. Together with the three anti-slip pads 14 on the bottom surface of the three support plates 13, they can enhance the friction between the warning sign and the ground, prevent the warning sign from sliding under wind or slight impact, and improve its stability under different ground conditions.

[0020] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4 Each guide rod 602 has a buffer spring 607 fitted on its outer surface. The two ends of each buffer spring 607 are in contact with the outer surface of the support plate 601 and the outer surface of the buffer plate 603, respectively. Each buffer plate 603 has a limiting slide rod 15 fixedly connected to one side of the support plate 601. The outer surface of each limiting slide rod 15 is slidably connected to the inside of the support plate 601. The limiting slide rods 15 on the side of the buffer plate 603 near the support plate 601 are slidably connected to the inside of the support plate 601, which can limit the movement direction of the buffer plate 603, prevent the buffer plate 603 from deviating during a collision, ensure that the buffer anti-collision mechanism 6 always plays a buffering role in the preset direction, and improve the stability of the buffering effect.

[0021] When this utility model is used in urban renewal construction scenarios, the warning sign is first placed inside the transparent housing 4. The reflector 5 on the outside of the upright plate 3 will reflect light under illumination, allowing pedestrians and vehicles to notice the presence of the warning sign from different angles and obtain warning information in a timely manner. At this time, the chassis 1 and the column 2 provide stable support for the upright plate 3, ensuring that the transparent housing 4 and the reflector 5 can continuously play their role in information transmission and warning.

[0022] When an external object collides with the warning sign, it first contacts the buffer pad 605 of the buffer anti-collision mechanism 6. The buffer pad 605 initially absorbs part of the collision force, and then pushes the buffer plate 603 to move towards the support plate 601. The movement of the buffer plate 603 causes the guide rod 602 to slide inside the support plate 601. The buffer spring 607 on the outer surface of the guide rod 602 is compressed, generating a reverse elastic force, which further offsets the collision energy. At the same time, the limiting plate 604 moves with the guide rod 602, and the buffer washer 606 on one side of it contacts the support plate 601, reducing the friction and collision damage between the limiting plate 604 and the support plate 601. The limiting plate 604 can also prevent the guide rod 602 from coming out of the support plate 601, ensuring the integrity of the buffer structure, preventing the collision force from being directly transmitted to the column 2 and the plate 3, and protecting the core components from damage.

[0023] If the position of the warning sign needs to be adjusted, the universal wheels 10 on the bottom of the chassis 1 can be used to move the warning sign. After reaching the designated position, the threaded rod 12 inside the threaded cylinder 11 is rotated so that the support plate 13 and anti-slip pad 14 at the bottom of the threaded rod 12 are in close contact with the ground. The support plate 13 increases the contact area with the ground, and the anti-slip pad 14 enhances the friction with the ground. The two work together to stably fix the warning sign on the ground, preventing it from moving at will. This ensures that the warning sign can continue to play a warning role in the designated position throughout the entire urban renewal construction period, protecting the safety of pedestrians and vehicles around the construction area. The design of the warning sign for the entire urban renewal effectively solves the problem that the main support structure is easily damaged by collisions with external vehicles due to the lack of an external buffer and anti-collision structure.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
