Description

Technical Field

[0001] The utility model relates to the technical field of fire emergency lights, in particular to a prompting light for a fire emergency passage. Background Technique

[0002] Fire emergency lighting fixtures are the most common type of fire protection products. Modern buildings generally need to install fire emergency lighting fixtures. When people evacuate, they need to bend down and walk along the wall, so they generally have indicating arrows and are installed at a low position on the wall.

[0003] The Chinese patent discloses a multifunctional LED fire emergency lighting fixture with the publication number CN218768701U, which includes a fire emergency light body. Two lighting lamps are fixedly installed at the top of the fire emergency light body. A smoke alarm is fixedly installed on the left side of the bottom of the fire emergency light body. A loudspeaker is fixedly installed on the right side of the bottom of the fire emergency light body. A rear cover is arranged on the back of the fire emergency light body. For this multifunctional LED fire emergency lighting fixture, by setting the lighting lamps, the emergency light emits bright light and can guide the escapees at night. The smoke alarm senses the smell of smoke generated by the fire and gives an alarm effect to prompt the on-site personnel to evacuate. The loudspeaker can emit an alarm guiding signal after an accidental disaster and can guide the escapees to the escape passage according to the sound. The fan will generate wind to dissipate heat inside the rear cover, and ventilation and heat dissipation are carried out through the heat dissipation holes, so as to ensure that the inside of the LED fire emergency lighting fixture will not be damaged due to overheating, thereby improving the service life of the LED fire emergency lighting fixture.

[0004] However, it still has the following disadvantages: The device uses indicating arrows to guide people to evacuate, but the device is installed at a low position on the wall and is easily damaged by children, or may malfunction due to being hit and squeezed during people's movement and goods handling. For this reason, we propose a prompting light for a fire emergency passage to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a prompting light for a fire emergency passage to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A prompting light for a fire emergency passage, including a fire indicator light. An installation frame is fixedly connected to the outer surface of the fire indicator light. An installation device is arranged above the installation frame. The installation device includes a protection part;

[0007] The protection part includes a protection shell and a second electromagnetic block. The outer surface of the bottom end of the protection shell slidably penetrates the inner wall of the installation frame and extends below the installation frame. Through holes are opened in the inner wall of the installation frame. The outer surface of the second electromagnetic block is fixedly connected to the inner wall of the through hole;

[0008] Above the mounting bracket is provided with a hoisting part;

[0009] The hoisting part includes a wire harness roller, a rotating block, a rotating shaft, a mounting box and a buffer block. The front and rear end faces of the mounting box are threadedly penetrated with mounting bolts. The bottom surface of the mounting box is open. The top outer surface of the buffer block extends into the mounting box and is slidably connected to the inner wall of the mounting box. The mounting bracket is rotatably sleeved on the outer surface of the rotating shaft through a bearing. The rotating block and the wire harness roller are both fixedly sleeved on the outer surface of the rotating shaft.

[0010] Further improvement lies in that the protection part further includes a magnetic block. A groove is formed on the top surface of the protection shell, and the inside of the groove communicates with the rear of the protection shell. The outer surface of the magnetic block is fixedly connected to the inner wall of the protection shell. By providing the second electromagnet, the protection shell and the magnetic block, it is convenient to protect the front of the fire indicator when a fire does not occur.

[0011] Further improvement lies in that the hoisting part further includes a magnetic strip, a first electromagnetic block, a steel wire rope and a spring. The steel wire rope is wound inside the wire harness roller. The bottom end of the steel wire rope is fixedly connected to the inner wall of the wire harness roller. The top end of the steel wire rope is fixedly connected to the front of the buffer block. By providing the steel wire rope, the rotating shaft and the wire harness roller, it is convenient to lift the mounting bracket and the fire indicator, reducing the risk of damage to the fire indicator.

[0012] Further improvement lies in that the bottom end of the spring is fixedly connected to the top surface of the buffer block, and the top end of the spring is fixedly connected to the inner wall of the mounting box. By providing the spring, the mounting box and the buffer block, and using the elasticity of the spring, it is convenient to buffer the impact force when the mounting bracket and the fire indicator fall.

[0013] Further improvement lies in that a mounting groove is formed on the inner wall of the mounting bracket, the outer surface of the first electromagnetic block is fixedly connected to the inner wall of the mounting groove, a placement groove is formed on the outer surface of the rotating block, and the outer surface of the magnetic strip is fixedly connected to the inner wall of the placement groove. By providing the magnetic strip, the first electromagnet and the rotating block, when the first electromagnet is powered off, the mounting bracket and the fire indicator naturally fall to the lower part of the wall.

[0014] Further improvement lies in that a smoke sensor is fixedly connected to the back of the mounting bracket. After the smoke sensor detects smoke, the first electromagnetic block and the second electromagnetic block are powered off. When a power failure occurs during a fire, the fire indicator falls to the designated position, indicating the direction of the safety exit for people walking forward bent over.

[0015] Further improvement lies in that a mounting hole is formed on the back of the mounting bracket, and an elastic wire harness positioning rod is fixedly connected to the inner wall of the mounting hole, which is convenient for positioning the wire harness.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the warning light used in the fire emergency passage, by setting a wire harness roller, a rotating block, a rotating shaft, a magnetic strip, a first electromagnetic block, a steel wire rope and a buffer block, the mounting bracket and the fire warning light are suspended at a high position by the steel wire rope, preventing the fire warning light from being damaged by extrusion and collision. When the first electromagnet is powered off, the first electromagnet no longer attracts the magnetic strip, causing the mounting bracket and the fire warning light to fall, so that the fire warning light is located at a low position on the wall. When people bend forward, it is convenient to indicate the direction of the safety exit for the trapped people; by setting an installation box, a spring and a buffer block, when the mounting bracket falls, the buffer block is buffered by the elastic force of the spring to reduce the impact force received when the fire warning light falls; by setting a protective shell, a magnetic block and a second electromagnetic block, the second electromagnet attracts the magnetic block, so that the protective shell protects the front of the fire warning light, reducing the probability of damage to the fire warning light caused by impact. After power-off, the protective shell moves downward, and the pointing light of the fire warning light leaks out to indicate the direction of the safety exit for people.
