Description

Technical Field

[0001] This utility model relates to the field of trolleys, specifically to a portable traffic cone trolley. Background Technology

[0002] Traffic cones, also known as road barriers, are used to place in the middle of roads, dangerous areas, and road construction sites, etc. They are placed around or in other appropriate locations where it is necessary to temporarily separate traffic flow, guide traffic, direct vehicles to bypass dangerous sections, and protect construction site facilities and personnel.

[0003] When an emergency occurs on a highway, patrol officers need to establish a safety zone, which is typically 150 meters long and requires 15 maintenance cones. Each cone is 90 centimeters high and weighs about 4.5 kilograms, so the total weight of 15 cones is 67.5 kilograms. If the patrol officers can only move the cones by hand, it will test their physical strength and the establishment of the safety zone will take a long time.

[0004] Patent CN212670388U discloses a traffic cone trolley for road engineering, specifically including a manual trolley and a storage component mounted on the manual trolley. The manual trolley includes a horizontally arranged rectangular storage bin, with front and rear wheels rotatably mounted below the base plate. A mounting plate is mounted on the upper surface of the base plate, and a handle for user gripping is fixedly mounted on the top of the mounting plate. The storage component includes a storage bin with its opening facing upwards. An outlet is provided on the outer circumference of the storage bin, parallel to its axial direction. A mounting groove is provided on the inner wall of the storage bin, arranged radially. A compression spring is provided in the mounting groove. One end of the compression spring is fixedly connected to the bottom of the mounting groove, and the other end extends freely and is suspended. A pressure plate is fixedly mounted on the suspended end, parallel to the axial direction of the storage bin. The pressure plate is used to press the traffic cone against the inner wall of the storage bin. A matching arc-shaped guide plate is connected to the top of the pressure plate, and the concave surface of the arc-shaped guide plate fits against the opening of the storage bin. This patent describes a method for storing traffic cones by incorporating storage components on a traffic cone cart, thus facilitating the storage and transportation of traffic cone stacks. However, while the storage bins can hold the traffic cones, they are placed directly on the cart's floor, failing to provide any secure support or stability to the contents during transport. Furthermore, the carts themselves are already quite large and inconvenient for storage; adding a storage component further complicates the process. Utility Model Content

[0005] The purpose of this invention is to provide a portable traffic cone cart to solve the problem that existing traffic cone carts cannot secure traffic cones during transportation.

[0006] To solve the above-mentioned technical problems, this utility model provides a portable traffic cone cart, including a frame, a support rod hinged to the frame by a first self-locking folding mechanism, and a handrail installed at the rear of the frame; the first self-locking folding mechanism makes the support rod upright and self-locked to the frame.

Detailed Implementation

[0023] like Figure 1 and Figure 2 The portable traffic cone cart shown includes a frame 1, a support rod 2 hinged to the frame via a first self-locking folding mechanism, and a handrail 4 mounted at the rear of the frame. The first self-locking folding mechanism 31 keeps the support rod 2 upright and self-locked to the frame 1. The frame 1 has wheels at its bottom, and the rear wheels of the frame 1 can also be swivel wheels with brakes to ensure smooth operation on ramps and prevent slippage.

[0024] This invention involves installing a support rod 2 on a vehicle frame 1 and using a self-locking folding mechanism to mount the support rod 2 onto the frame 1. When transporting traffic cones, the support rod 2 is rotated to remain upright with respect to the frame 1, and then locked in place by the self-locking mechanism. The traffic cone is then secured to the support rod 2, which limits its movement and prevents it from falling off the frame 1. When the traffic cone is in place or when transporting other goods that do not require the support rod 2's restraint (such as traffic signs), the support rod 2 is rotated along the first self-locking folding mechanism 31 to remain horizontal with respect to the frame 1, thus no longer occupying space on the frame 1. This traffic cone is compatible with various standard traffic cones and is suitable for establishing safe zones in various scenarios, including traffic accidents, disabled vehicles blocking the road, and temporary vehicle parking.

[0025] According to one embodiment of this application, the frame 1 is a rectangular frame structure; a crossbeam 3 is provided at the lower middle part of the frame 1, and the bottom end of the support rod 2 is connected to the middle part of the crossbeam 3 through a first self-locking folding mechanism 31. By setting the crossbeam 3, the connection point of the support rod 2 can be lower than the frame 1. When the road cones are not needed and the support rod 2 needs to be retracted, the horizontal height of the frame 1 can be kept no higher than the horizontal plane of the frame, so as to avoid the frame 1 protruding and affecting the movement of other goods.

[0026] According to one embodiment of this application, at least one longitudinal beam 11 is provided on each side of the crossbeam 3, and the two ends of the longitudinal beam 11 are fixedly connected to the rectangular frame. By providing the longitudinal beams 11, not only can the stability of the frame 1 be enhanced, but it is also convenient to place traffic cones.

[0027] According to one embodiment of this application, the distance between the crossbeam 3 and the two adjacent longitudinal beams 11 is less than the radius of the traffic cone. The longitudinal beams 11 provide support to the sidewalls of the traffic cone, facilitating the maintenance of the traffic cone's balance during transportation.

[0028] According to one embodiment of this application, the handrail frame 4 includes two connecting rods and a handrail; the handrail is connected between the top ends of the two connecting rods, and the bottom ends of the two connecting rods are hinged to the frame 1 via a second self-locking folding mechanism 41. The handrail frame is connected to the frame 1 via the second self-locking folding mechanism 41, and when the trolley is not in use, the handrail frame 4 can be folded along the second self-locking folding mechanism 41 so that the handrail frame 4 is placed horizontally on the frame 1 for easy storage and transportation.

[0029] According to one embodiment of this application, a mounting plate 42 is provided between two connecting rods, and a safety warning unit is provided on the mounting plate 42. The safety warning unit includes a warning light 5 and an indicator light 6 detachably mounted on the mounting plate 42, with the warning light 5 and indicator light 6 facing away from the vehicle frame. By setting the warning light 5 and indicator light 6, the traffic cones can be deployed to warn and guide oncoming vehicles. By using the combination of warning light 5 and indicator light 6, the warning distance can be greater than 200 meters, highlighting the early warning capability.

[0030] According to one embodiment of this application, such as Figure 3 As shown, warning light 5 is a strip strobe light, with both ends detachably mounted to the top of mounting plate 42 via the first mounting component. A strobe light, also known as a flashing light, uses electronic means (such as a capacitor-based microcontroller programmable IC) to make the light source flash slowly or quickly, serving as a warning. Warning light 5 has a built-in battery and charging function.

[0031] According to one embodiment of this application, the first mounting assembly includes a fixing cover 51, an L-shaped connector 52, and a first suction cup 53; the open end of the fixing cover 51 is detachably connected to the end of the strobe light; the vertical part of the L-shaped connector 52 is detachably connected to the side of the fixing cover 51 away from the strobe light, and the horizontal part of the L-shaped connector 52 is provided with the first suction cup 53 on the side away from the strobe light. The top and sides of the mounting plate 42 have a smooth structure, and the end of the strobe light can be directly inserted into the fixing cover 51, and then the strobe light is clamped in the middle by the two first mounting assemblies.

[0032] According to one embodiment of this application, indicator light 6 is a directional signal light, and a second suction cup (not shown in the figure) is provided on the back of the directional signal light. The directional signal light, also known as an arrow light, is used to guide vehicles behind in turning. The second suction cup is a high-strength suction cup, which allows for easy installation and removal of the directional signal light.

[0033] According to one embodiment of this application, both the first self-locking folding mechanism 31 and the second self-locking folding mechanism 41 are 90° self-locking folding hinges. Self-locking folding hinges are hardware accessories used in furniture, folding tables, doors, windows, and other similar applications, and their self-locking function can be achieved through angle adjustment. This application uses 90° self-locking folding hinges to achieve the uprighting and folding functions of the handrail and support rod.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
