Description

Technical Field

[0001] The present invention relates to the technical field of triangular warning signs, and particularly relates to a hand-thrown triangular warning sign. Background Art

[0002] According to relevant regulations, on conventional roads, when a motor vehicle breaks down or has a traffic accident, a triangular warning sign should be set at a sufficient distance behind the vehicle. When setting up the existing triangular warning signs, the driver of the motor vehicle needs to take it out from the trunk, unfold it first, and then hold it in front of the chest and walk to the rear of the vehicle to place it, which is very inconvenient and dangerous; and in actual use, many drivers are reluctant to walk, and the erection distance is relatively close, resulting in poor warning effect; in addition, when there are disputes or casualties in the accident and it is inconvenient to leave the scene, setting up the existing triangular warning signs is also a big problem. Summary of the Invention

[0003] The purpose of the present invention is to provide a hand-thrown triangular warning sign to solve the deficiencies existing in the triangular warning signs in the prior art.

[0004] The technical solution adopted by the present invention is: a hand-thrown triangular warning sign, including a triangular warning sign, support feet, and a base. The support feet are fixedly connected to the outer side of the bottom of the triangular warning sign. It is characterized in that: it further includes a support arm, a tension spring, a counterweight, and a directional umbrella. The support arm is rotatably connected between the triangular warning sign and the base. The two ends of the tension spring are respectively connected to the support arm and the base. The counterweight is arranged in front of the base through a front arm. The directional umbrella is connected to the back of the base;

[0005] The triangular warning sign is composed of 4 reflectors connected end to end to form a foldable triangular shape. Among them, 2 reflectors are used as the two side plates of the triangular warning sign. The tops of the two side plates are connected by a rotating shaft I. A torsion spring is sleeved on the rotating shaft I between the two side plates. The outer sides of the bottoms of the two side plates are fixedly connected to the support feet; the other 2 reflectors are connected by a rotating shaft II at one end and used as the bottom plate of the triangular warning sign. The two ends of the bottom plate are respectively connected to the bottoms of the two side plates;

[0006] The base includes a limit shoulder, a hook ear, and two side plates. The limit shoulder is connected to the top of the front ends of the two side plates. The middle parts of the two side plates are recessed to form a limit platform. The rear ends of the two side plates protrude upward to form a baffle. The hook ear is installed on the outer side wall of the front end of the side plate;

[0007] The support arm includes a connecting shaft, a limiting rod, a support rotating shaft, and a support rod. The upper part of the support rod is connected to the connecting shaft. The middle part of the support rod is connected to the limiting rod. The bottom of the support rod is connected to the support rotating shaft. Among them, the limiting rod is perpendicular to the connecting shaft, and the limiting rod is parallel to the support rotating shaft;

[0008] The connecting shaft sleeve of the support arm is in the rotating shaft II on the bottom side plate of the triangular warning sign, and the supporting rotating shaft of the support arm is rotatably connected with the supporting rotating shaft holes at the front ends of the two side plates of the base;

[0009] One end of the extension spring is connected to the hook ear of the base, and the other end of the extension spring is connected to the limit rod of the support arm, and the spring force of the extension spring is greater than that of the torsion spring;

[0010] In the folded state, the warning triangle and the support rod of the support arm are stuck between the two baffles at the rear of the base, and the limit rod of the support arm is stuck on the limit platform of the base;

[0011] In the unfolded state, the support rod of the support arm is held by the limiting shoulder of the base and is perpendicular to the base, and the triangular warning sign stands upright on the base through the support rod of the support arm.

[0012] A further technical solution is that the inner sides of the two side plates of the triangular warning sign are connected with red soft material fluorescent areas, and in the folded state, the fluorescent areas are stored between the gaps between the two side plates of the triangular warning sign.

[0013] Its further technical solution is: the rear end of the forearm is rotatably connected to the forearm shaft hole at the front ends of the two side plates of the base through a damping shaft, the front end of the forearm is fixedly connected to the counterweight block, and in the folded state, the forearm is folded backwards and stored between the two side plates of the base.

[0014] A further technical solution is that the forearm is an L-shaped structure.

[0015] A further technical solution is that the counterweight block is made of hard wear-resistant material.

[0016] A further technical solution is that the directional umbrella is made of soft material, and is connected to the back of the base baffle through a directional umbrella rope, and the length of the directional umbrella rope is greater than the length of the folded triangular warning sign.

[0017] Due to the adoption of the above technical solution, the hand-thrown warning triangle of the present invention has the following beneficial effects:

[0018] 1. Convenient and safe layout:

[0019] A hand-thrown triangular warning sign of the present invention. In the event of a traffic accident, the triangular warning sign can be thrown and placed. The forearm is folded forward to be fully extended and kept in a straight line with the base. Hold the tail of the base, with the forearm and the counterweight as the head, and the head facing downwards. After building up strength, it is thrown towards the oncoming vehicle. When the hand-thrown triangular warning sign falls to the ground from the air, due to the instantaneous impact force, the forearm and the base as a whole rotate slightly relative to the support arm, breaking the balance. The support rod of the support arm is pulled up from the limit platform under the pulling force of the tension spring, causing the support rotating shaft of the support arm to rotate rapidly until the support rod of the support arm is restricted by the limit shoulder of the base. At this time, the support rod of the support arm drives the triangular warning sign to change from a horizontal posture to an upright posture. At the same time, during the upright process, the triangular warning sign in the folded state breaks away from the restraint of the rear baffle of the base and automatically unfolds under the action of the torsion spring, enabling the triangular warning sign to be quickly deployed. There is no need to hold it in front of the chest and walk to the rear of the vehicle to place it manually, which is simple and convenient and can ensure personal safety.

[0020] 2. Good warning effect:

[0021] Since the forearm of a hand-thrown triangular warning sign of the present invention is of an L-shaped structure and uses less material, both the forearm and the base can be made of aluminum sheet metal material, which has high strength and light weight to reduce the weight of the entire device and facilitate throwing it far enough. The counterweight is made of hard and wear-resistant material. Because the counterweight will rub against the ground during the process of touching the ground and sliding forward after touching the ground, it is necessary to ensure a certain degree of wear resistance. The mass of the counterweight ensures that the hand-thrown triangular warning sign device can be thrown far enough by hand, so as to ensure that in the event of a traffic accident, the triangular warning sign can be placed at a sufficient distance and has a good warning effect.

[0022] 3. Since a hand-thrown triangular warning sign of the present invention can be thrown and placed, it can enable people to quickly complete the deployment without leaving the accident scene. It is easy to set up the triangular warning sign, and its unfolding is automatically completed under the action of the torsion spring, saving the steps and time of manual unfolding.

[0023] 4. A hand-thrown triangular warning sign of the present invention can automatically align the direction during throwing under the action of the counterweight, ensuring that it faces the oncoming vehicle in the exact rear direction. Even if it tilts during the throwing process, it can automatically return to the correct position.

[0024] 5. The directional umbrella of a hand-thrown triangular warning sign of the present invention is made of a soft material and can be kneaded arbitrarily for convenient storage. The directional umbrella is connected behind the base baffle through a directional umbrella rope. The length of the directional umbrella rope is greater than the length of the folded triangular warning sign, so that the directional umbrella can be fully unfolded in the air without being interfered by the folded triangular warning sign. The air resistance generated by the directional umbrella is moderate and does not overly reduce the throwing distance.

[0025] 6. When the hand - thrown and placed triangular warning sign of the present invention is not in use, the fluorescent area of the red soft - quality material is stored between the gaps of the two side plates of the triangular warning sign. The support rod of the triangular warning sign and the support arm is stuck between the two baffles at the rear of the base, the limiting rod of the support arm is stuck on the limiting platform of the base, and the front arm is folded backward and stored between the two side plates of the base to reduce the volume for convenient storage.

[0026] 7. For the hand - thrown and placed triangular warning sign of the present invention, the 4 reflective plates of the triangular warning sign serve as the red retro - reflective area, and the inner sides of the two side plates of the triangular warning sign are connected with the fluorescent area of the red soft - quality material, meeting the technical requirements specified in the latest national standard of the triangular warning sign, "GB 19151 - 2003 Motor Vehicle Triangular Warning Sign", and can be used as a regular, qualified, and convenient - to - use triangular warning sign on motor vehicles.

[0046] Example:

[0047] A hand - thrown triangular warning sign includes a triangular warning sign 1, a support foot 3, a base 4, a support arm 2, a tension spring 5, a counterweight 7 and a directional umbrella 8. The support foot is fixedly connected to the outer side of the bottom of the triangular warning sign. The support arm is rotatably connected between the triangular warning sign and the base. Both ends of the tension spring are respectively connected to the support arm and the base. The counterweight is made of a hard and wear - resistant material, and the counterweight is arranged in front of the base through a front arm 6;

[0048] The triangular warning sign is formed by 4 reflectors 13 connected end - to - end into a foldable triangular shape. Among them, 2 reflectors are longer and serve as the two side plates of the triangular warning sign. The tops of the two side plates are connected by a rotating shaft Ⅰ11. A torsion spring 15 is sleeved on the rotating shaft Ⅰ between the two side plates. The outer sides of the bottoms of the two side plates are both fixedly connected to the support foot. The other 2 reflectors are shorter. One end of the 2 short reflectors is connected by a rotating shaft Ⅱ14 to obtain a long reflector, which serves as the bottom plate of the triangular warning sign. Both ends of the bottom plate are respectively connected to the bottoms of the two side plates;

[0049] The 4 reflectors of the triangular warning sign serve as a red retro - reflection area. A red soft - material fluorescent area 12 is connected to the inner sides of the two side plates of the triangular warning sign. The red soft - material fluorescent area is not connected to the bottom plate of the triangular warning sign;

[0050] The base is made of aluminum sheet metal material and includes a limit shoulder 41, a hook ear 45 and two side plates 46. The limit shoulder is connected to the top of the front ends of the two side plates. The middle parts of the two side plates are concave to form a limit platform. The rear ends of the two side plates bulge upward to form a baffle 44. The hook ear is installed on the outer side wall of the front end of the side plate;

[0051] The support arm includes a connecting shaft 21, a limiting rod 22, a supporting shaft 23 and a supporting rod 24, wherein the upper part of the supporting rod is connected to the connecting shaft, the two sides of the middle part of the supporting rod are connected to the limiting rod, and the bottom of the supporting rod is connected to the supporting shaft, wherein the limiting rod and the connecting shaft are perpendicular to each other, and the limiting rod and the supporting shaft are parallel to each other;

[0052] The connecting shaft sleeve of the support arm is in the rotating shaft II on the bottom side plate of the triangular warning sign, and the supporting rotating shaft of the support arm is rotatably connected with the supporting rotating shaft hole 43 at the front end of the two side plates of the base;

[0053] One end of the tension spring is connected to the hook ear of the base, and the other end of the tension spring is connected to the limit rod of the support arm on the same side of the hook ear. The spring force of the tension spring is greater than that of the torsion spring, so that when throwing, the hand-thrown warning triangle sign is first transformed into an upright posture, and then the unfolding of the warning triangle sign is completed;

[0054] The forearm is an L-shaped structure made of aluminum sheet metal. The rear end of the forearm is rotatably connected to the forearm shaft hole 42 at the front ends of the two side plates of the base through a damping shaft, and the front end of the forearm is fixedly connected to the counterweight block.

[0055] The directional parachute is made of soft material and is connected to the back of the base baffle through a directional parachute rope 9. The length of the directional parachute rope is greater than the length of the folded triangular warning sign.

[0056] In the folded state, the red soft material fluorescent area is stored in the gap between the two side plates of the triangular warning sign, the triangular warning sign and the support rod of the support arm are stuck between the two baffles at the rear of the base, the limit rod of the support arm is stuck on the limit platform of the base, and the forearm is folded backward and stored between the two side plates of the base. At this time, the triangular warning sign is in a horizontal posture, the limit rod on the support arm is in a straight line with the support shaft and the hook ear on the side of the base, and is in a balanced position. The tension on the tension spring cannot cause the support arm to rotate relative to the base.

[0057] In the unfolded state, the support rod of the support arm is held by the limiting shoulder of the base and is perpendicular to the base, and the triangular warning sign stands upright on the base through the support rod of the support arm.

[0058] A method for using a hand-thrown warning triangle of the present invention:

[0059] Fold the forearm forward until it is fully extended and in a straight line with the base. Hold the tail of the base with your hand. With the forearm and the counterweight as the head and the head facing downwards, build up strength and then swing it towards the oncoming vehicle. When the hand-thrown triangular warning sign drops from the air and touches the ground instantaneously, due to the instantaneous impact force, the whole forearm and the base rotate slightly relative to the support arm, breaking the balance. The support rod of the support arm is pulled up from the limit platform under the pulling force of the tension spring, causing the support rotating shaft of the support arm to rotate rapidly until the support rod of the support arm is restricted by the limit shoulder of the base. At this time, the support rod of the support arm drives the triangular warning sign to change from a horizontal posture to an upright posture. At the same time, during the upright process, the triangular warning sign in the folded state breaks away from the restraint of the tail baffle of the base and automatically unfolds under the action of the torsion spring, enabling the triangular warning sign to be quickly deployed to achieve a warning effect, which is simple, convenient and safe.
