Description

Technical Field

[0001] This utility model belongs to the technical field of emergency valves for bus doors, specifically a safety emergency valve for bus doors. Background Technology

[0002] A bus door safety emergency valve is a safety device used in the door systems of buses, long-distance coaches, and other vehicles. Its main function is to ensure that the doors can be opened quickly and safely in an emergency, allowing passengers to evacuate promptly. Its main functions include: emergency opening: in the event of a power failure or system malfunction, the safety emergency valve can manually or automatically release the door, ensuring passengers can escape smoothly; anti-pinch protection: when closing the door, the safety emergency valve can prevent passengers from being trapped, enhancing passenger safety.

[0003] Meanwhile, a push-button type emergency valve for bus doors, application number CN202220839306.6, includes an emergency valve body and a valve cover. The emergency valve body has a slot, and an adjusting cavity is located inside the body, communicating with the slot. A traction groove is provided on the inner wall of the slot, located above the adjusting cavity. A movable groove is provided on the bottom surface of the traction groove, communicating with the adjusting cavity through the movable groove. Mounting plates are fixedly mounted on both symmetrical inner walls of the adjusting cavity. Slider blocks are movably mounted on the traction groove, the movable groove, and the adjusting cavity. On one side of the assembly plate, an adjusting rod is fixedly mounted on the slider. The adjusting rod is located between the two assembly plates, and one end of the adjusting rod extends movably through to the outside of the emergency valve body. A push plate is fixedly mounted on the adjusting rod, which is located in the adjusting cavity. A telescopic spring is mounted on the adjusting rod, and both ends of the telescopic spring are fixedly mounted to the push plate and the assembly plate, respectively. A second elastic locking plate is fixedly mounted on the upper surface of the slider. The second elastic locking plate is movably mounted to the locking groove and the traction groove, respectively. Pressing the adjusting rod causes the push plate and the assembly plate to be stressed by the telescopic spring, causing the telescopic spring to contract, and the second elastic locking plate on the slider can be moved easily.

[0004] However, the following problems were found in the implementation of the relevant technology: In emergency situations (such as vehicle rollover or door jamming), the button can be turned in both directions. Rescue personnel or passengers may mistakenly turn the button in the closing direction due to tension or unfamiliarity with the operation. This may delay the opening time or even cause the door to jam further (such as the emergency valve linkage mechanical structure locking in the opposite direction), causing the people inside the vehicle to miss the best escape window.

[0005] Therefore, we propose a safety emergency valve for bus doors. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a bus door safety emergency valve, which has the advantages of allowing the rotating rod to rotate only in one direction, eliminating the need to judge the direction and reducing the operational error rate during emergencies, while requiring pressing and rotating to open the emergency valve, thus reducing the risk of accidental triggering.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bus door safety emergency valve, comprising a mounting plate, an emergency valve body fixedly connected to the upper surface of the mounting plate, a valve body control rod provided on the emergency valve body, a spring fixedly connected to the inner surface of the valve body control rod, a push rod fixedly connected to the top end of the spring, the push rod being slidably connected to the valve body control rod, a connecting block fixedly connected to the upper surface of the push rod, a rotating rod fixedly connected to the outer surface of the connecting block, a control handle fixedly connected to the other end of the rotating rod, a housing fixedly connected to the upper surface of the mounting plate, a slot provided on the housing, and a limit groove provided above one side of the slot.

[0008] Preferably, the spring is located inside the valve body control rod and the top rod, with the bottom end of the spring inside the valve body control rod and the top end of the spring inside the top rod.

[0009] Preferably, the rotating rod is slidably connected to the limiting groove, and the rotating rod is slidably connected to the slot.

[0010] Preferably, the outer surface of the control handle is provided with anti-slip texture.

[0014] Preferably, the mounting plate is red.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model restricts the rotation direction of the rotating rod by cooperating with the slot, so that it can only rotate in one direction. The unidirectional design makes the operation unique, eliminating the need to judge the direction. The unidirectional design can be triggered by simply rotating in the only direction, which can be quickly mastered even for first-time users. It directly shortens the emergency response time, reduces the error rate in emergency operations, eliminates the need to judge the direction, shortens the operation reaction time, and reduces human error.

[0016] 2. This utility model, through the cooperation of the valve body control rod, spring, push rod, connecting block, rotating rod, housing, limit groove and slot, requires pressing and rotating to open the emergency valve. It requires the operator to perform two actions, which significantly reduces the risk of accidental triggering, prevents single accidental triggering, avoids accidental opening in daily life, and at the same time ensures the stability of the valve stem, prevents accidental displacement during long-term use, and ensures that the valve remains fully closed when not in operation.

The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0029] Working principle: During use, the rotating rod 7 is located on one side within the slot 11. The spring 4 inside the valve body control rod 3 applies elastic force to the push rod 5, thus lifting the push rod 5. The push rod 5 drives the connecting block 6 and the rotating rod 7 upwards, causing the rotating rod 7 to slide into the limiting groove 10. The limiting groove 10 then fixes the position of the rotating rod 7. In case of danger, first open the glass cover 15 on the protective shell 14, then press the control handle 8. The control handle 8 drives the rotating rod 7 to slide from the limiting groove 10 into the slot 11, and then push... The control handle 8 causes the rotating rod 7 to slide within the slot 11, and the rotating rod 7 can only slide in one limited direction within the slot 11. Thus, the rotating rod 7 drives the push rod 5 and the valve body control rod 3 to rotate and open the emergency valve body 2. The emergency valve body 2 opens at a controlled rate, and the medium is gradually released through the designed flow-limiting channel to prevent instantaneous pressure shock waves from being transmitted to the vehicle's air circuit. After the emergency valve body 2 reaches the set safety pressure or time window, the valve stabilizes again in the reserved open state or returns to the closed state to ensure overall safety and system controllability.
