Description

Technical Field

[0001] The utility model relates to vehicle warning equipment technology, in particular to a triangular warning sign. Background Art

[0002] The triangular warning sign for motor vehicles is a warning sign that should be set up when the driver needs to stop on the highway after encountering a vehicle breakdown.

[0003] The existing support legs for folding of the warning triangle are all fixed to the triangle bottom plate using other parts, and such parts require additional work to install, which will increase the additional labor installation cost and parts cost.

[0004] Therefore a low-cost triangle warning sign is urgently needed. Utility Model Content

[0005] The purpose of the utility model is to propose a triangular warning sign to address the problem of high production cost of existing triangular warning signs. The triangular warning sign omits parts for assembling and fixing supporting feet and a bottom plate while ensuring the supporting function, thereby effectively saving labor costs and parts costs.

[0006] It should be noted that, in the present utility model, unless otherwise specified, the specific meaning of "including" in relation to composition limitations and descriptions includes both open-ended "including", "comprising" and similar meanings, and closed-ended "composed of", "composed of" and similar meanings.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a triangular warning sign, including a base plate and a left plate and a right plate that can form a triangular structure with the base plate, the bottoms of the left plate and the right plate are respectively hinged to the two ends of the base plate, and the two ends of the bottom of the base plate are respectively provided with a base, and the base is provided with a mounting groove, and two mounting holes are provided on the base plate corresponding to the opening of the mounting groove, and the first supporting foot and the second supporting foot are respectively hinged in the two mounting holes; a supporting groove is provided between the base and the base plate, and the supporting groove is used to accommodate the first supporting foot and the second supporting foot that are screwed out; and a receiving groove wall for accommodating the middle sections of the first supporting foot and the second supporting foot (a total of four supporting feet) is provided in the middle of the bottom of the base plate.

[0008] Furthermore, the first support leg is provided with a first rotation axis and a first pointed head at both ends, a first notch is provided at the side of the first pointed head close to the ground, and two first inclined surfaces are provided on the first support leg close to the first pointed head. The provision of the first inclined surface can make the end of the first support leg thinner, and the first notch can reduce the contact area between the first support leg and the ground, while increasing the friction with the ground, thereby preventing the warning triangle from sliding on the ground.

[0009] Furthermore, the horizontal section of the first support leg near the first rotation axis is provided with a Z-shaped bend, and the second support leg has no Z-shaped bend. In this way, after the offset installation, the first support leg and the second support leg can be offset after being stored, reducing the space occupied by the first support leg and the second support leg, so that the overall volume of the triangular warning sign is reduced.

[0010] Furthermore, the second supporting leg is provided with a second rotating shaft and a second pointed head at both ends, a second notch is provided on the side of the second pointed head close to the ground, and two second inclined surfaces are provided on the second supporting leg close to the second pointed head. The provision of the second inclined surface can make the end of the second supporting leg thinner, and the second notch can reduce the contact area between the second supporting leg and the ground, while increasing the friction with the ground, thereby preventing the warning triangle from sliding on the ground.

[0011] Furthermore, the bottom sheet adjacent to the support groove is a support wall, and the support wall is an inclined surface with a certain slope. The support wall is inclined downward from the center line of the bottom sheet to the edge. The support groove formed between the base and the support wall has a certain slope, so that the first support leg and the second support leg have a certain slope after being unfolded, so that the triangular warning sign can stand on the ground and have a certain height from the ground.

[0012] Furthermore, a convex point and a stop groove are provided on the base adjacent to the support groove at positions corresponding to the mounting holes. When in use, the first support leg and the second support leg are respectively rotated toward the stop groove on the bottom plate, and the stop groove can limit the first support leg and the second support leg from continuing to rotate, and the convex point on the base can limit the first support leg and the second support leg, and they cannot rotate in the opposite direction without external force.

[0013] Furthermore, a crossbeam parallel to the bottom plate is arranged below the bottom plate, and the bottom plate and the crossbeam are connected by connecting ribs, thereby strengthening the strength of the entire bottom plate. An open first vent is formed between the bottom plate, the crossbeam and the connecting rib, and second vents are respectively provided at both ends of the bottom plate. Wind can pass through the first vent and the second vent, thereby reducing resistance and facilitating wind tunnel testing.

[0014] Furthermore, the accommodating groove wall is fixed in the middle of the bottom of the bottom film through a linking wall, and the accommodating groove wall can accommodate the first supporting foot and the second supporting foot.

[0015] Furthermore, a plurality of clamping points and pressure strips are provided in the receiving groove wall, the clamping points are provided at both ends of the receiving groove wall, the pressure strips are provided in the middle of the receiving groove wall, the upper and lower spacings of the relative clamping points are slightly smaller than the outer diameter of the supporting foot (the first supporting foot or the second supporting foot), and the relative pressure strip spacings are adapted to the outer diameter of the supporting foot (the first supporting foot or the second supporting foot). After the first supporting foot and the second supporting foot are received, the clamping points can fix the first supporting foot and the second supporting foot in the receiving space, and they will not rotate out without external force, and the supporting feet will not shake against each other to generate noise; the pressure strips can fix the first supporting foot and the second supporting foot in the receiving space and press them tightly, and they will not shake to generate noise.

[0016] The utility model has a simple, reasonable and compact structure and has the following advantages compared with the prior art:

[0017] 1) The utility model triangular warning sign directly installs and fixes the support feet in the base, which eliminates the installation and fixing parts of the support feet while ensuring the supporting function, greatly improving production efficiency and saving labor and additional parts costs.

[0018] 2) The supporting foot of the utility model is provided with an inclined surface and a notch groove, which can reduce the contact area with the ground and increase the friction with the ground to prevent the triangular warning sign from sliding on the ground.

[0019] 3) The Z-shaped bending design of the first supporting leg of the utility model can enable the first supporting leg and the second supporting leg to be staggered after being stored, thereby reducing the space occupied by the first supporting leg and the second supporting leg, thereby reducing the overall volume of the triangular warning sign.

[0020] 4) The support wall of the utility model is an inclined surface with a certain slope, so that the first support leg and the second support leg have a certain slope after being unfolded, so that the triangular warning sign can stand on the ground at a certain height from the ground.
