Technical Field
[0001] This utility model relates to the field of safety warning equipment, and in particular to a safety warning device. Background Technology
[0002] Road safety warning equipment is an important facility for ensuring road traffic safety. It can be divided into four main categories: static warning equipment, dynamic warning equipment, intelligent warning equipment, and auxiliary warning equipment. Among them, the crash barrier, which belongs to the category of static warning equipment, is a road safety component that combines warning and protective functions.
[0003] Currently, crash barriers are primarily structurally complete columns mounted on the ground via a fixed base at the bottom. During use, reflective strips are attached to the outer wall of the crash barrier to achieve a warning effect. However, crash barriers are often used in conjunction with warning tape, with the ends of the tape fixed to the crash barrier (using clips, binding, or adhesive). After both are in use, the tension of the warning tape may become insufficient over time. In this case, the tape connection needs to be removed and reinstalled. If the number of crash barriers involved in the warning tape is large, the adjustment process becomes quite cumbersome.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0019] See Figure 1 and Figure 2 This utility model provides a safety warning device, which includes a column 1 and a rotating warning strip connecting sleeve 2 fitted onto the column 1; wherein, the outer wall of the column 1 is fitted with a reflective strip 10, which has good reflectivity and can play a warning role at night with the help of an external light source.
[0020] When the warning strip is installed, its connecting end is fixed to the warning strip connecting sleeve 2. In terms of structure, the outer wall of the warning strip connecting sleeve 2 is provided with a connecting structure 11 for connecting the warning strip. This connecting structure can be a snap (shown in the figure), a hook and loop fastener, or other connecting structures.
[0021] A positioning structure is provided between the column 1 and the warning strip connecting sleeve 2 to drive the warning strip connecting sleeve 2 to rotate unidirectionally around the column 1 by a predetermined angle. When adjusting the tension of the already assembled warning strip (attached to the warning strip connecting sleeve 2), it is only necessary to rotate the warning strip connecting sleeve 2 by a predetermined angle, and the warning strip connecting sleeve 2 will partially wrap the warning strip around itself to achieve the tension adjustment.
[0022] The positioning structure includes a pawl 3 disposed on the first connecting structure and a ratchet 4 disposed on the second connecting structure. In the first embodiment, the pawl 3 is installed on the warning strip connecting sleeve 2; the ratchet 4 is installed on the column 1. Alternatively, in reverse assembly, the pawl 3 is installed on the column 1; the ratchet 4 is installed on the warning strip connecting sleeve 2. Utilizing the unidirectional positioning effect of the pawl 3 and ratchet 4 cooperation structure, the positioning effect of the warning strip connecting sleeve 2 during the tensioning process is optimized. During adjustment, it is only necessary to hold the warning strip connecting sleeve 2 and rotate it at a predetermined angle. After adjustment and release, the warning strip connecting sleeve 2 immediately enters the angle locking state, making the adjustment process convenient and quick.
[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In the second embodiment (this embodiment), in order to avoid over-adjustment or the device being driven by other external forces to rotate the warning strip connecting sleeve 2 to an unsuitable position during transportation, it is necessary to set up a structure to manually cancel the engagement state of the pawl 3 and the ratchet 4 in order to reset the warning strip connecting sleeve 2.
[0024] The pawl 3 and ratchet 4 are driven by a driving component, causing them to disengage or engage. Specifically, the column 1 has an internal cavity and an opening at the top; the opening is covered by a sealing cap 6, and a rotation positioning structure is provided between the sealing cap 6 and the column 1, which can be the engagement of a protrusion 12 and a groove, to prevent the sealing cap 6 from rotating relative to the column 1;
[0025] The ratchet 4 is connected to the cover 6 via a first connecting rod 8;
[0026] The side wall of the column 1 has a groove 7 for limiting the rotation angle of the warning strip connecting sleeve 2. The pawl 3 is installed on a mounting ring located inside the column 1, and the mounting ring is connected to the warning strip connecting sleeve 2 via a second connecting rod 9 passing through the groove 7. To cancel the engagement between the pawl 3 and the ratchet 4, simply lift the cover 6 to move the pawl 3 upward and disengage it from the ratchet 4. After disengagement, the warning strip connecting sleeve 2 can rotate in the opposite direction of the aforementioned rotation adjustment to reset. After rotating to the appropriate position, lower the cover 6, and the pawl 3 and ratchet 4 will re-engage, allowing for readjustment.
[0027] See Figure 3 and Figure 4 Preferably, to facilitate the re-engagement of the pawl 3 with the ratchet 4 after disengagement, the pawl engages with the ratchet 4 facing upwards or downwards. In this embodiment, the pawl engages with the ratchet 4 facing upwards.
[0028] In summary, this utility model provides a safety warning device, including a column and a rotating warning strip connecting sleeve fitted onto the column. The outer wall of the column is fitted with a reflective strip, which has good reflectivity and can provide a warning effect at night with the aid of an external light source. During installation, the connecting end of the warning strip is fixed to the warning strip connecting sleeve. Structurally, the outer wall of the warning strip connecting sleeve is provided with a connecting structure for connecting the warning strip. This connecting structure can be a snap-fit, hook-and-loop fastener, or other connecting structure. A positioning structure is provided between the column and the warning strip connecting sleeve to drive the warning strip connecting sleeve to rotate unidirectionally around the column by a predetermined angle. When adjusting the tension of the assembled warning strip (fitted to the warning strip connecting sleeve), it is only necessary to rotate the warning strip connecting sleeve by a predetermined angle, and the warning strip connecting sleeve will partially wrap around itself to achieve the tension adjustment. This utility model facilitates the tension adjustment of warning strips connected to crash barriers, as adjustment can be made simply by rotation, making the adjustment process convenient.
