Description

Technical Field

[0001] This utility model belongs to the field of sign technology, specifically a convenient plug-in emergency sign. Background Technology

[0002] With the rapid development of road construction and the frequent occurrence of safety accidents, these incidents are becoming increasingly widespread. Consequently, the workload for handling emergencies and maintaining roads is also constantly increasing. To address this situation, the use of emergency signs has become particularly important. These signs guide people to take appropriate actions during an accident or choose suitable evacuation routes in emergency situations. They not only help maintain order and reduce chaos but also improve rescue efficiency and ensure the safety of personnel. Therefore, the proper placement and use of emergency signs plays a crucial role in ensuring public safety and smooth traffic flow.

[0003] In current traffic management, the installation and use of emergency signs have become an indispensable measure. They not only provide clear directions for drivers and pedestrians, helping them make correct judgments in the face of emergencies, but also provide rescue personnel with route guidance for rapid response. These signs effectively guide traffic flow, avoid congestion caused by accidents, and thus reduce the probability of secondary accidents. Furthermore, the rational layout of emergency signs can help rescue teams quickly locate the accident scene, shorten rescue time, and improve the success rate of rescue efforts. Therefore, strengthening the scientific planning and management of emergency signs is an important way to improve road safety management and emergency response capabilities.

[0004] Given the increasing severity of road safety issues and the high level of public safety concern, the installation and use of emergency signs are particularly crucial. They provide clear guidance for the public in emergencies, helping people remain calm and take swift and effective measures in the face of unexpected situations. These signs play a vital role not only at accident scenes but also in daily traffic, providing timely information to help drivers and pedestrians avoid potential risks. Therefore, ensuring the visibility, accuracy, and timely updating of emergency signs is essential for maintaining road safety and improving emergency response speed.

[0005] In modern transportation systems, the scientific layout and effective management of emergency signs are crucial for ensuring traffic safety. They not only provide drivers and pedestrians with essential information to help them react quickly in emergencies, but also offer vital route guidance to rescue personnel, ensuring their rapid arrival at the accident scene. Furthermore, the proper placement of emergency signs helps optimize traffic flow, reducing traffic delays and congestion caused by accidents, thereby lowering the risk of secondary accidents. Therefore, continuously optimizing the layout and content of emergency signs is a key strategy for improving road safety and emergency response efficiency.

[0006] In emergency situations, the use of signs should be as simple and quick as possible. However, existing emergency signs require fasteners to be fixed to brackets. If a sign needs to be fixed or replaced, the fasteners must first be loosened, which undoubtedly increases the time and difficulty of the operation. Furthermore, in emergencies, the time of rescue personnel is extremely valuable and should not be wasted on cumbersome procedures. More importantly, once a sign is fixed, its orientation cannot be adjusted, causing considerable inconvenience to rescue workers. Utility Model Content

[0007] To overcome the above-mentioned defects, this utility model provides a convenient plug-in emergency sign, which solves the problems in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a convenient plug-in emergency sign, including a bracket, a stator fixedly connected to the bracket, a rotor rotatably connected inside the stator, a rotating shaft coaxially fixedly connected to the rotor, and a retaining ring fixedly connected to the rotating shaft.

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figures 1-5 As shown, this utility model provides a technical solution:

[0027] A convenient plug-in emergency sign includes a bracket 1, a stator 2 fixedly connected to the bracket 1, a rotor 3 rotatably connected inside the stator 2, a rotating shaft 4 coaxially fixedly connected to the rotor 3, and a retaining ring 5 fixedly connected to the rotating shaft 4. The operator can adjust the direction of the sign 14 by rotating the rotating shaft 4, thus facilitating its use.

[0028] A sleeve 6 is fixedly connected to the retaining ring 5. A fixed frame 7 is fixedly connected to the inner wall of the sleeve 6. A telescopic rod 8 is fixedly connected to the fixed frame 7. A movable frame 9 is fixedly connected to one end of the telescopic rod 8. A first spring 10 is sleeved on the telescopic rod 8. The two ends of the first spring 10 abut against the fixed frame 7 and the movable frame 9 respectively. When the movable frame 9 is subjected to force, the telescopic rod 8 will retract, and the first spring 10 will also retract. However, since the elastic force of the first spring 10 is small, it will accumulate elastic potential energy under the action of a large external force.

[0029] Two first connecting rods 11 are rotatably connected to the fixed frame 7, and two second connecting rods 12 are rotatably connected to the movable frame 9. One end of the first connecting rod 11 is rotatably connected to one end of the second connecting rod 12. When the movable frame 9 moves closer to the fixed frame 7, the angle between the first connecting rod 11 and the second connecting rod 12 decreases, and at the same time, the second connecting rod 12 moves from both sides toward the middle. At a certain moment, the two second connecting rods 12 will be parallel to each other.

[0030] A magnet 13 is fixedly connected to one side of the second connecting rod 12. An indicator 14 is provided on the sleeve 6, and a plug 15 is fixedly connected to the indicator 14. The plug 15 is slidably connected inside the sleeve 6, and the end face of the plug 15 abuts against the end face of the moving frame 9. The plug 15 is made of magnetic material. The external forces mentioned above all come from the pressure of the end face of the plug 15 against the moving frame 9. This pressure causes the second connecting rod 12 to move from both sides toward the middle, and finally clamp the two sides of the plug 15 in a parallel shape. At this time, the magnet 13 on the second connecting rod 12 is attracted to the plug 15. This force is greater than the elastic force of the spring, so the entire insertion and removal mechanism is in force balance at this time, and the indicator 14 is fixed. If the indicator is pulled out, the magnet 13 will separate from the plug 15. At this time, there is no magnetic force, and the elastic potential energy accumulated by the first spring 10 is released at this time. The telescopic rod extends, and the second connecting rod 12 also reopens, making it convenient to insert the indicator 14 again.

[0031] Several pin holes are radially formed on the inner wall of stator 2. A sleeve 6 is slidably connected in each pin hole. A second spring 17 is installed in each pin hole, with its two ends abutting against the end face of the pin hole and the end face of the pin 16, respectively. Several conical holes are radially formed on the side wall of rotor 3. The conical head of the pin 16 abuts against the conical hole. Returning to the rotating mechanism, the pins 16 arranged in a ring on the stator, under the elastic force of the second spring 17, cause the pins 16 to abut against the conical hole of rotor 3, thereby fixing stator 2 and rotor 3 relatively. When the shaft 4 is rotated, the shaft 4 transmits torque to the rotor 3. Since the contact surface between the tapered hole on the rotor 3 and the pin 16 is inclined, relative sliding will occur between the two. The second spring 17 contracts, and the pin 16 is pushed out of the tapered hole. At this time, the shaft 4 continues to rotate until the pin 16 is aligned with the next tapered hole on the edge of the rotor 3. At this time, the second spring 17 returns to its original state, and the pin 16 is pushed out again and pushed into the tapered hole. The stator 2 and the rotor 3 are fixed relative to each other again. This reciprocating motion can achieve the fixed angle rotation of the indicator.

[0032] Three support legs 18 are fixedly connected to the bottom of the support. Foot pads 19 are fixedly connected to the bottom of the support legs 18. The foot pads 19 are made of rubber and can provide a firm grip for the device to prevent the support 1 from deflecting when the rotating shaft 4 is rotated.

[0033] The working principle of this utility model is as follows:

[0034] The operator can adjust the direction of the indicator 14 by rotating the pivot 4 for easier use. When the moving frame 9 is subjected to force, the telescopic rod 8 will retract, and the first spring 10 will also retract. However, since the elastic force of the first spring 10 is relatively small, it will accumulate elastic potential energy under the action of a larger external force. When the moving frame 9 moves closer to the fixed frame 7, the angle between the first connecting rod 11 and the second connecting rod 12 decreases, and the second connecting rod 12 moves from both sides towards the middle. At a certain moment, the two second connecting rods 12 will be parallel to each other. The aforementioned external forces all come from the end face of the plug 15 on the moving frame. The pressure of the frame 9 causes the second connecting rod 12 to move from both sides toward the middle, eventually clamping the two sides of the plug 15 in a parallel shape. At this time, the magnet 13 on the second connecting rod 12 is attracted to the plug 15. This force is greater than the elastic force of the spring, so the entire insertion and removal mechanism is in force balance and the indicator 14 is fixed. If the indicator is pulled out, the magnet 13 will separate from the plug 15. At this time, there is no magnetic force, and the elastic potential energy accumulated by the first spring 10 is released. The telescopic rod extends, and the second connecting rod 12 also reopens to facilitate the insertion of the indicator 14 next time.

[0035] Returning to the rotating mechanism, the pins 16 arranged in a ring on the stator, under the elastic force of the second spring 17, cause the pins 16 to abut against the conical holes of the rotor 3, thus fixing the stator 2 and the rotor 3 relative to each other. If the rotating shaft 4 is rotated at this time, the rotating shaft 4 transmits torque to the rotor 3. Since the contact surface between the conical holes on the rotor 3 and the pins 16 is inclined, relative sliding will occur between the two. The second spring 17 contracts, and the pins 16 are pushed out of the conical holes. If the rotating shaft 4 is rotated again, the pins 16 will be aligned with the next conical hole on the edge of the rotor 3. At this time, the second spring 17 will return to its original position, and the pins 16 will be pushed out again and inserted into the conical holes. The stator 2 and the rotor 3 will be fixed relative to each other again. This reciprocating motion can achieve the fixed-angle rotation of the indicator. The foot pad 19 can provide a firm grip for the device to prevent the bracket 1 from deflecting when the rotating shaft 4 is rotated.

[0036] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
