[0001] The present invention relates to the field of road engineering, and more particularly to a road cone retracting and deploying device. Background Art

[0002] Traffic cones are a common traffic safety device, also known as road marker cones, traffic cones, or warning cones. They are commonly used to mark road construction or traffic accident sites, reminding drivers to slow down, take a detour, or be aware of dangerous areas. Cones are typically made of orange plastic and have a conical shape, wide at the base and narrow at the top. This design helps improve visibility and, due to the stability of the cone, is less likely to collapse in strong winds. Cones are also flexible to minimize damage to vehicles and pedestrians. However, setting up traffic cones typically requires a large number of cones at regular intervals, which is laborious and inconvenient to retract. Summary of the Invention

[0023] like Figure 4-5 As shown, this example can achieve the effect of fixing the road cone.

[0024] The traffic cone retracting and deploying device comprises a circular ring 101 with a side frame 102 welded to the right side of the circular ring 101. A hollow rod 107 is hingedly connected to the side frame 102. A hook rod 108 is slidably connected to the hollow rod 107. The lower end of the hook rod 108 has a beveled hook portion. The tip of the traffic cone can be inserted into the circular ring 101, and then the hollow rod 107 is rotated so that the hook portion of the hook rod 108 contacts the bottom of the traffic cone, thereby securing the traffic cone and facilitating its deployment and retraction.

[0025] like Figure 4-5As shown, this example can achieve the effect of fixing traffic cones of different heights between the ring 101 and the hook.

[0026] Since the hollow rod 107 is threadedly connected with a fastening screw 1, the fastening screw 1 presses on the hook rod 108, and then the hook rod 108 slides on the hollow rod 107, thereby adjusting the distance between the hook portion and the ring 101, and then fixing traffic cones of different heights between the ring 101 and the hook portion.

[0027] like Figure 4-5 As shown, this example can achieve the effect of making the hook portion of the hook rod 108 press against the lower end of the traffic cone through elastic force.

[0028] Since the outrigger 104 is welded to the side frame 102, the two ends of the elastic rod 105 are respectively welded to the hollow rod 107 and the outrigger 104. The elastic rod 105 applies force to the hollow rod 107 to rotate close to the traffic cone, thereby making the hook portion of the hook rod 108 press against the lower end of the traffic cone through elastic force, preventing the traffic cone from falling off.

[0029] like Figure 4-5 As shown in Figures 8-9, this example can achieve the effect of driving multiple road cones to approach the ground in sequence and setting the road cones on the ground.

[0030] Since the traffic cone retracting and deploying device also includes a round seat 401, three square rods 402 are welded to the round seat 401 in a ring shape, each square rod 402 is slidably connected to an L-shaped frame 103, and a fastening screw 2 is threadedly connected to the L-shaped frame 103, and the fastening screw 2 is pressed on the square rod 402. A circular ring 101 is welded to each L-shaped frame 103, and then a circular ring 101 can be set on each of the multiple square rods 402 on the round seat 401, and each circular ring 101 can be connected to a traffic cone. The round seat 401 is driven to rotate about its own axis and is rotatably connected to a truck equipped with multiple traffic cones. Then, a person on the truck puts the traffic cones in from a high place, and then drives the multiple traffic cones to approach the ground in sequence, and the traffic cones are set on the ground.

[0031] like Figure 4-5 As shown in Figures 8-9, this example can achieve the effect of driving multiple L-shaped frames 103 and multiple rings 101 to rotate.

[0032] Because the upper shaft 409 is welded to the rear side of the round base 401 and rotatably connected to the horizontal frame 201 via a bearing, the round base 401 can be rotated on the horizontal frame 201 via the upper shaft 409, thereby driving the multiple L-shaped frames 103 and the multiple circular rings 101 to rotate, thereby retracting and deploying the traffic cones. The L-shaped frames 103 can slide on the square rod 402 to adjust the distance between the circular rings 101 and the upper shaft 409, thereby adjusting the distance between the multiple traffic cones and, in turn, the spacing between the multiple traffic cones when they are set on the ground.

[0033] like Figure 4-7 As shown, this example can achieve the effect of making the traffic cone fall to the ground.

[0034] Because the rear side of hollow rod 107 is welded to diagonal rod 106, and vertical frame 204 is welded to the underside of horizontal frame 201, telescopic rod 1 202 is fixed to the lower end of vertical frame 204. Telescopic rod 1 202 is welded to the end of push rod 203, which can press against diagonal rod 106. When the circular ring 101 equipped with the traffic cone rotates close to the ground, it drives telescopic rod 1 202 to extend, causing push rod 203 to press against diagonal rod 106, causing hollow rod 107 and hook rod 108 to rotate outward on side frame 102, allowing the hook to disengage from the underside of the traffic cone and allowing the cone to fall to the ground. To place the traffic cone, a person on the truck manually inserts the cone into circular ring 101 and moves it up and down. Similarly, to retract the cone, a person below manually inserts the cone into circular ring 101 and moves it onto the truck.

[0035] like Figure 8-9 As shown, this example can achieve the effect of driving multiple rings 101 to continuously rotate and place traffic cones on the road.

[0036] Since the rear end of the upper shaft 409 is welded with a pulley 403, the rear end of the upper shaft 409 is rotatably connected to the upper part of the rotating rod 405 through a bearing, the rear end of the lower shaft 407 is rotatably connected to the lower end of the rotating rod 405 through a bearing, the rear end of the lower shaft 407 is welded with a pulley 406, and the pulley 403 and the pulley 406 are driven by a belt. The front end of the lower shaft 407 is connected to a wheel 408 through a screw. The wheel 408 needs to be in contact with the ground. The road cone retracting and releasing device is fixed on the truck. When the truck equipped with the road cone moves, the wheel 408 is driven to rotate, and the wheel 408 drives the lower shaft 407 and the pulley 406 to rotate. The pulley 406 drives the pulley 403 and the upper shaft 409 to rotate, thereby driving the round seat 401, multiple square rods 402 and multiple rings 101 to rotate, so that the multiple rings 101 rotate continuously to set the road cone on the road.

[0037] like Figure 4-7 As shown, this example can achieve the effect of fixing the traffic cone retracting device on the truck.

[0038] The left and right ends of the cross frame 201 are connected to hangers 205 via screws. Each hanger 205 has a hanging slot 206 at its rear. A third fastening screw is threadedly connected to the rear of each hanger 205, with the end of the third fastening screw entering the corresponding hanging slot 206. The two hangers 205 can be hung on the cargo box of a truck through the hanging slot 206. The third fastening screw is then driven to rotate against the cargo box, thereby securing the traffic cone retracting device to the truck.

[0039] like Figure 6-9As shown, this example can achieve the effect of driving wheel 408 to press against the ground.

[0040] Since the rotating rod 405 is provided with a long hole 404, the vertical moving rod 301 is vertically slidably connected to the horizontal frame 201, and the lower end of the vertical moving rod 301 is fixed with an insertion shaft 302, which is inserted into the long hole 404. Two retaining rings 306 are fixed on the insertion shaft 302, and the two retaining rings 306 are respectively located on both sides of the rotating rod 405. When the vertical moving rod 301 slides vertically on the horizontal frame 201, it can drive the insertion shaft 302 to move vertically, thereby driving the upper part of the rotating rod 405 to rotate on the upper shaft 409, thereby driving the wheel 408 to press against the ground. When the truck moves, the wheel 408 is driven to rotate by friction.

[0041] like Figure 6-7 As shown, this example can prevent the wheel 408 from getting stuck when encountering an obstacle.

[0042] Since a spring 305 is welded to the upper end of the vertical moving rod 301, a flat rod 304 is welded to the upper part of the spring 305, and a telescopic rod 2 303 is fixed on the flat rod 304, and the movable end of the telescopic rod 2 303 is connected to one of the hangers 205 by a screw, when the telescopic rod 2 303 is extended or retracted, the flat rod 304 is driven to rise and fall, thereby driving the spring 305 to press downward, so that the driving spring 305 is pressed toward the vertical moving rod 301 through elastic force, so that the vertical moving rod 301 is elastically pressed toward the rotating rod 405 and the wheel 408. When the wheel 408 encounters an obstacle, it can jump up through elasticity to prevent the wheel 408 from being stuck when encountering an obstacle.
