In addition, further, the outer edge of the base 4 is arc-shaped. The base 4 with the circular arc-shaped edge can reduce resistance, so that the roadblock cone body 1 can rotate by taking a contact point of the base 4 and the ground as an origin.
The distance between the top ends of the two guide rails 10 is small, the distance between the bottom ends of the two guide rails 10 is large, when the roadblock cone main body 1 topples, the two guide rails 10 are in a state that the bottom ends are high and the top ends are low, and the double cones 21 and the guide rails 10 form a double-cone upslope structure, so that the double cones 21 can roll towards the outer side of the telescopic guide rod 19, the integral gravity center of the roadblock cone main body can be moved to the outer side of the base 4, and the roadblock cone main body 1 can automatically stand. Hollow bulb 2 can be convenient for take the removal of this roadblock awl, and when roadblock awl main part 1 emptys, certain height also can be raised on the top of roadblock awl main part 1 to hollow bulb 2 to can make the focus of roadblock awl main part 1 deviate from the lower extreme of roadblock awl main part 1, the follow-up roadblock awl main part 1 of being convenient for relies on centrobaric change to stand automatically. The arc-shaped stop 16 limits the maximum rolling distance of the bi-cones 21 and also prevents the bi-cones 21 from falling out when the telescopic spring rod 17 is retracted and extended.
The second embodiment is as follows:
specifically, when the roadblock cone main body 1 is toppled over, one side of the annular support 7 of the automatic standing device 5, on which the fan-shaped weight 8 is installed, rotates to the lower side under the action of gravity, that is, the two guide rails 10 rotate to the upper side of the fan-shaped weight 8. The fan-shaped weight 8 is arranged to enable the guide rail 10 to rotate to the upper side of the fan-shaped weight 8 by the annular support 7 no matter which direction the roadblock cone main body 1 inclines, so that a double-cone uphill structure formed by the double cones 21 and the guide rail 10 can play a role conveniently.
Specifically, when the roadblock cone body 1 stands, the telescopic spring rods 17 of the automatic standing device 5 are all in a compressed state, and when the roadblock cone body 1 topples over, the telescopic spring rods 17 all extend outwards under the elastic action of the springs 18 and slide out the two telescopic guide rods 19 from the guide rails 10. When the two telescopic guide rods 19 slide out of the guide rail 10 under the action of the telescopic spring rods 17, the vertical height of the outer ends of the two telescopic guide rods 19 is smaller than the vertical height of the gravity center of the double cone 21 at the inner end of the guide rail 10. The double cones 21 roll outwards along the two guide rails 10 and the telescopic guide rods 19 under the action of gravity, and when the double cones 21 roll to the positions of the arc-shaped stop bars 16, the gravity center of the main body 1 of the road barrier cone moves to the outer side of the base 4. Thereby the flexible spring pole 17 outwards resumes natural state when roadblock awl main part 1 emptys pulls out flexible guide bar 19 from guide rail 10, the length of extension guide rail 10, further can make bipyramid 21 roll farther distance on guide rail 10, along with bipyramid 21 roll to the arc shelves strip 16 department on flexible guide bar 19 top, the focus of roadblock awl main part 1 shifts to the outside of base 4 gradually, rely on the effect of gravity, roadblock awl main part 1 uses the contact point on base 4 and ground to rotate as the initial point, stand roadblock awl main part 1 automatically.
In actual use, please refer to fig. 4-8, the outer surface of the road block cone body 1 is adhered with the reflective strip 3 to play a role of warning, and the hollow ball head 2 can facilitate the taking and moving of the road block cone; when the roadblock cone body 1 stands, the telescopic spring rods 17 of the automatic standing device 5 are in a compressed state and are not accommodated on two sides of the fan-shaped weighting block 8, and the telescopic guide rods 19 are contracted in the guide rails 10; when the road barrier cone body 1 is knocked over, a first bearing 6 is arranged between the annular support 7 and the inner surface of the base 4, a fan-shaped weight 8 is fixedly installed on the inner wall of one side of the annular support 7, and the fan-shaped weight 8 rotates to the lower part under the action of gravity, so that the two guide rails 10 rotate to the upper part of the fan-shaped weight 8; meanwhile, the telescopic spring rods 17 extend outwards under the elastic action of the springs 18 to restore the natural state, and the two telescopic guide rods 19 slide out of the guide rail 10 to prolong the length of the guide rail 10, and at the moment, the vertical height of the outer ends of the two telescopic guide rods 19 is smaller than the vertical height of the gravity center of the double cones 21 at the inner end of the guide rail 10, and at the moment, the gravity center of the whole device is located at the position A (as shown in fig. 4); the double-cone 21 and the guide rail 10 form a double-cone uphill structure, so that the double-cone 21 automatically rolls outwards on the guide rail 10, when the double-cone 21 rolls to the arc-shaped stop bar 16 at the top end of the telescopic guide rod 19, the gravity center of the road block cone body 1 gradually shifts to the outer side of the base 4, and the gravity center of the whole road block cone is located at the position B (shown in FIG. 5); then, under the action of gravity, the roadblock cone body 1 rotates by taking the contact point of the base 4 and the ground as an original point until the double cones 21 contact the ground (as shown in fig. 6); then, due to the existence of the fan-shaped weighting blocks 8, the center of gravity of the body 1 of the road-block cone is still positioned at the outer side of the base 4, and the arc-shaped stop bars 16 at the top ends of the telescopic guide rods 19 gradually sink and contact the ground (as shown in fig. 7); then the road-block cone body 1 will continue to rotate, and the telescopic guide rod 19 will extrude the telescopic spring rod 17 under the pressure brought by the fan-shaped weighting block 8, so that the telescopic guide rod 19 is contracted inside the guide rail 10, and in the process of gradually contracting the telescopic guide rod 19, the arrangement of the roller 20 can effectively reduce the friction between the arc-shaped barrier strip 16 and the ground, thereby facilitating the contraction until the road-block cone body 1 recovers the standing state (as shown in fig. 8), and completing the automatic standing process after the road-block cone body 1 is toppled over.
When the roadblock cone main body is toppled, the double cones and the guide rail form a double-cone uphill structure, the vertical height of the outer end of the telescopic guide rod is smaller than the vertical height of the gravity center of the double cones when the double cones are arranged at the inner ends of the guide rail, so that the double cones can automatically roll towards the lower outer end of the guide rail, the gravity center of the roadblock cone main body gradually deviates to the outer side of the base, the roadblock cone main body rotates by taking the contact point of the base and the ground as the original point under the action of gravity, then the telescopic spring rod is contracted into the guide rail under the pressure of the fan-shaped weighting block to finish the automatic standing action, the roadblock cone main body can automatically stand in time after toppling, manual lifting is not needed, and the safety of construction personnel or sites is guaranteed.
