Description

Technical Field

[0001] The utility model relates to the technical field of emergency valves, in particular to a safety emergency valve for a passenger car door. Background Art

[0002] The bus door emergency valve is a safety device used in the door systems of buses, coaches, and other vehicles. Its primary 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 door opening: In the event of a power failure or system malfunction, the emergency valve manually or automatically releases the door, ensuring a smooth escape for passengers; and anti-pinch protection: When closing the door, the emergency valve prevents passengers from being trapped, enhancing passenger safety.

[0003] In the prior art, the safety emergency valve used in bus doors is usually fixed at the top position of the bus door. When in use, it is necessary to open the valve cover and then turn the knob to start the emergency valve. However, when the valve cover cannot be opened in some emergency situations, it is difficult to open the valve cover and thus start the emergency valve. Therefore, we urgently need a safety emergency valve that can be started without opening the valve cover. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides the following technical solutions: a passenger car door safety emergency valve, comprising a mounting base and an emergency valve body fixedly mounted on the outer surface of the mounting base, and an emergency valve cover arranged on the outer side of the emergency valve body, the emergency valve body being welded and fixed to the outer surface of the mounting base, a support member being fixedly mounted on the outer surface of the emergency valve body, the support member being annular, a mounting groove being provided inside the support member, an outer valve body being fixedly mounted inside the mounting groove, the outer valve body being located on the outer side of the emergency valve body, an emergency valve cover being provided on the top end of the outer valve body, an adsorption mechanism being provided between the emergency valve cover and the outer valve body, a knob being rotatably provided inside the emergency valve body, a toggle rod being fixedly mounted on one side of the upper end of the knob, and a reset mechanism for the toggle rod being provided on the inner side of the outer valve body.

[0005] As an improvement to the above technical solution, a plurality of equally spaced mounting holes are provided around the interior of the mounting base plate.

[0006] As an improvement of the above technical solution, the adsorption mechanism includes a groove opened inside the top of the outer valve body, a magnet ring is fixedly installed inside the groove, a magnet is embedded in the lower surface of the emergency valve cover, and the positions of the magnet embedded in the lower surface of the emergency valve cover and the magnet ring correspond and are adapted.

[0007] As an improvement of the above technical solution, the reset mechanism includes an arc-shaped through groove No. 2 opened on the inner side of the outer valve body, and the arc-shaped through groove No. 2 is in the shape of a quarter arc. The inner side of the outer valve body is also provided with an arc-shaped slot, and the inner upper end of the arc-shaped through groove No. 2 is provided with an arc-shaped plug rod, one end of the arc-shaped plug rod is fixedly connected to the side surface of the toggle rod, and the other end of the arc-shaped plug rod is inserted into the inside of the arc-shaped slot, and the outer surface of the arc-shaped plug rod is sleeved with an arc spring, one end of the arc spring is fixedly connected to the toggle rod, and the other end of the arc spring is fixedly connected to the outer valve body.

[0008] As an improvement of the above technical solution, the frame of the emergency valve body is also provided with an arc-shaped through groove 1, which is in the shape of a quarter arc, and the positions of the arc-shaped through groove 1 and the arc-shaped through groove 2 correspond to each other, and one end of the toggle rod is movably arranged on the inner side of the arc-shaped through groove 1 and the arc-shaped through groove 2.

[0009] The beneficial effects of the present invention are as follows: an emergency valve body is arranged on the outer surface of the mounting base plate, and a knob is arranged inside the emergency valve body, and a toggle rod is fixedly installed on the outer side of the upper end of the knob. As the toggle rod moves, the knob can be driven to move, thereby opening the emergency valve. A reset mechanism is arranged on the outer side of the toggle rod. Under the action of the reset mechanism, the toggle rod can drive the emergency valve to start when it moves, and after the car door is opened, it quickly returns to its original position, thereby closing the emergency valve, thereby increasing convenience during use and preventing people from accidentally touching the emergency valve in normal times, thereby causing the emergency valve to open. The setting of the toggle rod can rotate the knob arranged inside the emergency valve body without opening the emergency valve cover, thereby further increasing convenience during use.

[0018] In this embodiment, an emergency valve body 2 is provided on the outer surface of the mounting base plate 1, and a knob 9 is provided inside the emergency valve body 2. At the same time, a toggle rod 6 is fixedly installed on the outer side of the upper end of the knob 9. As the toggle rod 6 moves, the knob 9 can be driven to move, thereby opening the emergency valve. A reset mechanism is provided on the outer side of the toggle rod 6. Under the action of the reset mechanism, the toggle rod 6 can drive the emergency valve to start when it moves, and after the car door is opened, it quickly returns to its original position, thereby closing the emergency valve, thereby increasing convenience during use and preventing people from accidentally touching the emergency valve in normal times, thereby causing the emergency valve to open. The setting of the toggle rod 6 can rotate the knob 9 provided inside the emergency valve body 2 without opening the emergency valve cover 3, further increasing convenience during use.

[0019] Specifically, a plurality of mounting holes 101 distributed at equal intervals are provided around the interior of the mounting base plate 1 , and the mounting holes 101 are used to cooperate with screws to complete vehicle installation.

[0020] Specifically, the adsorption mechanism includes a groove 402 opened inside the top of the outer valve body 4, a magnet ring 403 is fixedly installed inside the groove 402, and a magnet is embedded in the lower surface of the emergency valve cover 3.
