The base is equipped with an adjustment mechanism, which includes a fixing mechanism, a fixing sleeve, a threaded rod, a spring, a contact plate, a fixing plate, a retaining sleeve, and a receiving mechanism. The fixing sleeve is installed on the base, and the fixing mechanism is installed on the fixing sleeve. The fixing sleeve has a through hole, and the threaded rod is slidably connected in the through hole. The adjustment mechanism can precisely control the angle and stability of the warning light. Through the cooperation of the threaded rod, the adjusting nut, and the spring, the angle of the light body and the clamping force can be adjusted. This flexible adjustment function allows the operator to quickly adapt to different road and weather conditions, enhancing the practicality of the warning light and its ability to cope with severe weather. Through this mechanism, the light body can be fixed in the optimal warning position when needed, ensuring the effective coverage of the light and the maximum warning effect.
[0004] In construction sites, cones or railings are usually used to isolate construction areas. However, existing road warning lights are difficult to install quickly on various cone or railing structures, and cannot achieve the effect of individual installation and combined use, making them inconvenient and inflexible to use. Utility Model Content
[0005] The purpose of this utility model is to provide a road warning light for construction, in order to solve the problems in the above-mentioned background art where existing road warning lights are difficult to install quickly on various cones or guardrail structures, and cannot achieve the effect of individual installation and combined use, and are not convenient and flexible to use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a road warning light for construction, including a central pole, with a movable cover slidably connected to the outside of the central pole, and the movable cover being sleeved on the outside of the pipe structure;
[0007] The overall structure of the sports cover is a frustum. An upper hinge seat with equal spacing in a ring is fixedly connected to the top of the inner side of the sports cover. A lower hinge seat with equal spacing in a ring is fixedly connected to the outer side of the lower end of the central rod. A long connecting rod is hinged to the upper hinge seat, and a short connecting rod is hinged to the lower hinge seat. The end of the long connecting rod away from the upper hinge seat and the end of the short connecting rod away from the lower hinge seat are hinged to each other. A warning light assembly is installed on the top of the central rod.
[0008] Preferably, a limiting protrusion is provided at the hinge of the long connecting rod and the short connecting rod, and the limiting protrusion restricts the rotation angle of the hinge of the long connecting rod and the short connecting rod in the unfolded state, and the range of the inner angle formed by the long connecting rod and the short connecting rod is 40°-180°.
[0009] Preferably, a foot pad is fixedly connected to the outside of the short connecting rod. When the short connecting rod rotates to be perpendicular to the central rod, the foot pad and the lower end of the central rod share the same supporting plane.
[0010] Preferably, a lower operating sleeve is fixedly connected to the outer side of the upper end of the motion cover, a light box is fixedly connected to the top of the lower operating sleeve, and an upper operating sleeve is fixedly connected to the bottom of the light box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This road warning light for construction uses a sliding connection between the central rod and the moving cover, along with a hinged design of long and short connecting rods, to achieve rapid folding and unfolding. A spring provides automatic unfolding power, and limiting protrusions constrain the connecting rod angle within the range of 40°-180°, adapting to the installation requirements of different pipe diameters. The spring-driven adaptive pipe fixing mechanism causes the moving cover to automatically press down after release, driving the connecting rod to open outwards and tightly fit against the inner wall of the pipe. Suitable for pipes of various diameters, and with the coplanar support formed by the foot pads and the central rod, stable installation can be achieved without additional tools.
[0016] The integrated design of solar panels and rechargeable batteries provides a continuous power supply, reducing the frequency of battery replacements. It is particularly suitable for outdoor environments without power sources. The window structure of the lightbox not only allows light to pass through but also promotes air circulation, optimizes heat dissipation, and prevents overheating damage to LED chips and batteries. The enclosed structure effectively resists the effects of rain, dust, and other external environmental factors, improving the durability and long-term reliability of the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1: Please refer to Figure 1 - Figure 5This utility model provides the following technical solution: a road warning light for construction, including a central pole 1, with a movable cover 2 slidably connected to the outside of the central pole 1, the movable cover 2 being fitted onto the outside of a pipe structure; the movable cover 2 is a frustum-shaped structure, with an annularly distributed upper hinge seat 4 fixedly connected to the top of the inner side of the movable cover 2, and an annularly distributed lower hinge seat 5 fixedly connected to the outer side of the lower end of the central pole 1; a long connecting rod 6 is hinged to the upper hinge seat 4, and a short connecting rod 7 is hinged to the lower hinge seat 5; the end of the long connecting rod 6 away from the upper hinge seat 4 and the end of the short connecting rod 7 away from the lower hinge seat 5 are hinged together; a warning light assembly 3 is installed on the top of the central pole 1; Figure 3 and Figure 4 As shown, a limiting protrusion 8 is provided at the hinge of the long connecting rod 6 and the short connecting rod 7. The limiting protrusion 8 restricts the rotation angle of the hinge of the long connecting rod 6 and the short connecting rod 7 in the unfolded state. The range of the inner angle formed by the long connecting rod 6 and the short connecting rod 7 is 40°-180°. A foot pad 9 is fixedly connected to the outside of the short connecting rod 7. When the short connecting rod 7 rotates to be perpendicular to the center rod 1, the foot pad 9 and the lower end of the center rod 1 share the same supporting plane. A lower operating sleeve 10 is fixedly connected to the outer side of the upper end of the motion cover 2. A light box 12 is fixedly connected to the top of the lower operating sleeve 10. An upper operating sleeve 13 is fixedly connected to the bottom of the light box 12. A spring 11 is sleeved on the outside of the center rod 1. The upper end of the spring 11 is fixedly connected to the inside of the upper operating sleeve 13, and the lower end of the spring 11 is fixedly connected to the inside of the lower operating sleeve 10.
[0026] In the initial working state, the elastic force applied by the spring 11 drives the motion cover 2 to slide downward along the outside of the central rod 1, thereby causing the long connecting rod 6 to move downward synchronously. This allows the long connecting rod 6 and the short connecting rod 7 to gradually unfold through their upper and lower hinge points. The upper end of the long connecting rod 6 is hinged to the upper hinge seat 4 on the top of the inner side of the motion cover 2, and the lower end is hinged to the upper end of the short connecting rod 7. The lower end of the short connecting rod 7 is fixed to the lower hinge seat 5 on the outside of the lower end of the central rod 1. During the unfolding process, the limiting protrusion 8 applies a constraint, limiting the rotation angle at the hinge point of the long connecting rod 6 and the short connecting rod 7. The inner angle formed by the two is stably maintained within the range of 40° to 180° to prevent excessive folding or loosening. When the axis of the short connecting rod 7 rotates to a position perpendicular to the axis of the central rod 1, this state is firmly locked. At this time, the foot pad 9 on the outside of the short connecting rod 7 is aligned with the lower end of the central rod 1 on the same horizontal plane, forming a balanced support plane. At this time, the device can stand stably on its own in the road environment, and the motion cover 2 finally moves down to its lowest point.
[0027] When the user needs to install the device onto a pipe structure, an upward pushing force can be applied manually to the upper operating sleeve 13 and lower operating sleeve 10 at the bottom of the light box 12. This drives the motion cover 2 to slide upward along the outside of the central rod 1, causing the long connecting rod 6 to move upward through the upper hinge seat 4. This results in the inner angle formed by the long connecting rod 6 and the short connecting rod 7 gradually increasing. The change in the inner angle causes the hinge point to move closer to the central rod 1, thereby shrinking the overall size of the long connecting rod 6, the short connecting rod 7, and the central rod 1 into a compact folded state. After folding, the user can insert the device into the pipe structure; then, the upper operating sleeve 13 and lower operating sleeve 10 can be released. When the lower operating sleeve 10 is lowered, the elastic force of the spring 11 immediately drives the motion cover 2 to slide downward. During the downward movement, the motion cover 2 drives the long connecting rod 6 to move downward through the upper hinge seat 4, causing the short connecting rod 7 to rotate around the hinge point of the lower hinge seat 5. This causes the hinge point of the long connecting rod 6 and the short connecting rod 7 to move away from the center rod 1 until the hinge point of both is tightly attached to the inner wall of the pipe structure. After being attached, the hinge point of the long connecting rod 6 and the short connecting rod 7 applies a uniform pressure towards the outside to the inner wall of the pipe structure. Through the action of the motion cover 2, the long connecting rod 6 and the short connecting rod 7, the device is fixed at the end of the pipe, and the warning light assembly 3 is always located at the top of the center rod 1.
[0028] Example 2: Based on Example 1, please refer to... Figure 6 The following structure is also disclosed: the warning light assembly 3 includes a light box 12, a battery assembly 14 is fixedly connected inside the light box 12, and the light box 12 has equidistantly distributed windows on the outside; a solar panel 15 is fixedly connected to the top of the battery assembly 14, the solar panel 15 and the battery assembly 14 are electrically connected, and LED beads 16 are fixedly connected to the outside of the battery assembly 14 in a ring.
[0029] The light box 12 includes a rechargeable battery and corresponding electrical wiring. During the day or in an environment with light, the solar panel 15 on the top of the light box 12 actively receives ambient light energy and converts it into electrical energy through an electrical device that is fixedly connected to it, directly charging the rechargeable battery in the battery assembly 14.
[0030] The LED beads 16 are fixedly connected to the outside of the battery assembly 14 in a ring-shaped manner, and emit light to the outside of the light box 12 through equidistantly distributed windows. The windows match the ring distribution of the LED beads 16 to ensure that the light is emitted uniformly in a horizontal 360-degree range. In nighttime or low-light warning scenarios, the battery assembly 14 activates the LED beads 16, which emit high-intensity light and radiate it outward through the windows. The design of the window structure ensures that the light distribution has no dead angles and no dark areas, so that vehicles or pedestrians from any direction can clearly identify the warning signal. At the same time, the equidistant windows of the light box 12 promote effective heat dissipation and prevent internal components such as LED beads 16 or battery assembly 14 from overheating and being damaged. The overall encapsulation of the light box 12 provides physical protection for the solar panel 15, battery assembly 14, LED beads 16 and related circuits, withstands the influence of outdoor environment, and ensures that the equipment works reliably under various construction conditions.
