Description

Technical Field

[0001] The utility model relates to a three-sided cone, in particular to a durable arc-shaped rotationally molded three-sided cone. Background Art

[0002] Road cone is a road traffic isolation and warning facility.

[0003] At present, a Chinese patent with authorization announcement number CN213978698U discloses a road cone, including a cone and a base, the base includes a top plate, a bottom plate, and an outer plate, the top plate, the bottom plate, the outer plate, and the inner plate together form a closed cavity, and the rear surface of the cone is provided with a storage bin for placing a warning sign.

[0004] When the road cone is in use, the road cone is first placed at the required position, and then the base is weighted, the first cover is opened, and the second cover is closed at the same time, and then weight materials such as weighted sand or water are added into the cavity through the feeding port, so that the base can be weighted to avoid being blown. In some special places, when multiple warnings are required, the bin cover is opened, the warning sign in the storage bin is taken out, and it is fixed on the cover through the first detachable structure.

[0005] This type of road cone has good stability, but when it is not needed, the road cones are usually stacked together and taken from top to bottom. Due to the effect of their own pressure, there is usually a large friction between the road cones. Due to the friction between the palm and the cone surface, it is difficult to separate the road cones, which affects efficiency. Utility Model Content

[0013] As a preferred solution of the utility model, four placement grooves are provided on the baffle plate, and the four placement grooves are arranged along the length direction of the baffle plate.

[0014] To implement the above technical solution, four fingers except the thumb are placed in four placement grooves respectively, so that the downward pressing angle of the fingers is larger, so that the separation between the three-sided cones is more labor-saving and quick.

DETAILED DESCRIPTION

[0027] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0028] A durable arc-shaped roto-molded three-sided cone includes three trapezoidal plates 11 and a triangular plate 12, the cross section of the triangular plate 12 is a regular triangle. The trapezoidal plates 11 and the triangular plate 12 are integrally formed and enclose a receiving cavity. The three side walls of the triangular plate 12 are respectively fixedly connected to the three trapezoidal plates 11, the side walls of the trapezoidal plates 11 are connected end to end, and the trapezoidal plates 11 are inclined.

[0029] The outer wall of the trapezoidal plate 11 and the outer wall of the triangular plate 12 are both provided with a frosted layer, and the frosted layer is formed by granular protrusions on the surfaces of the trapezoidal plate 11 and the triangular plate 12. The trapezoidal plate 11 and the triangular plate 12 are both made of plastic.

[0030] A circular hole 2 is provided in the middle of the triangular plate 12, and the circular hole 2 connects the outer wall and the inner wall of the triangular plate 12. A guiding slope 21 is provided at the opening of the circular hole 2, and the guiding slope 21 is located on the side of the triangular plate 12 facing away from the accommodating cavity. A rope is passed through the circular hole 2 along the guiding slope 21, and multiple triangular cones can be strung together for easy transportation.

[0031] A connecting groove 3 with a waist-shaped cross section is provided at one end of the trapezoidal plate 11 close to the triangular plate 12 . The connecting groove 3 connects the inner wall and the outer wall of the trapezoidal plate 11 .

[0032] A horizontally arranged baffle plate 4 is fixedly connected to one side of the trapezoidal plate 11 facing the accommodating cavity. The baffle plate 4 is close to the lower edge of the connecting groove 3. Four placement grooves 41 are formed on the baffle plate 4. The four placement grooves 41 are arranged along the length direction of the baffle plate 4. The four fingers except the thumb correspond to the four placement grooves 41 respectively.

[0033] A pin 5 is rotatably connected to the side of the trapezoidal plate 11 facing the accommodating cavity, and a limiting plate 51 is fixedly connected to the outer wall of the pin 5. An elastic member 52 is fixedly connected between the limiting plate 51 and the trapezoidal plate 11, and the elastic member 52 is a spring. Through the elastic force of the elastic member 52, the limiting plate 51 tends to move closer to the baffle 4. The lower surface of the baffle 4 is used to conflict with the upper surface of the limiting plate 51.

The four fingers except the thumb are passed through the connection slot 3, and the thumb and palm are pressed against the outer wall of the trapezoidal plate 11, and downward pressure is applied to the limit plate 51. The pressure wheel 53 contacts the upper surface of the triangular plate 12 of the three-sided cone in the accommodating cavity. At this time, the three-sided cone located at the top has an upward trend, and the three-sided cone located in the accommodating cavity has a downward trend, so that the three-sided cone located at the top can be quickly separated from the three-sided cone below, greatly improving efficiency. The pressure wheel 53 rolls along the upper surface of the triangular plate 12, reducing friction and making the separation of the three-sided cones easier.
