Problems solved by technology

[0002] At present, firefighters’ lifesaving ropes are generally carried in a winding manner. When using them, they need to untie the ropes in the winding state, and perform operations such as knotting according to the required length or use method, and the operation efficiency is low; this type of rope is prone to occur between multiple ropes Knots between them will affect the use; the rope needs to be rewound after use, which is extremely inconvenient
Many inconvenient factors lead to the low utilization rate of fire-fighting life-saving ropes in disaster rescue. In case of emergency, it is not convenient to use such life-saving ropes to avoid danger quickly

Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0023] like figure 1 and figure 2 As shown, a multifunctional lifesaving device for firefighters includes a shell 1 with one end open and an end cover 2 that covers the opening of the shell 1 .

[0024] The housing 1 is specifically a hollow cylindrical structure. The main shaft 3 is fixed inside the housing 1. The main shaft 3 is located on the axis of the housing 1. The main shaft 3 is sequentially covered with an escape wheel 4, a rope winding wheel 5, and a winding wheel. Spring 6 and ratchet 7, rope winding wheel 5 and ratchet 7 are fixedly connected, and rotate on main shaft 3.

[0025] A pallet fork 8 is installed at a position corresponding to the escape wheel 4 in the housing 1 , and the end surface of the escape wheel 4 near the rope winding wheel 5 has a locking tooth 14 .

[0026] The end face of the rope winding wheel 5 near the si...

Abstract

The invention discloses a multifunctional firefighter lifesaving device, belonging to the field of firefighting equipment. The multifunctional firefighter lifesaving device comprises a shell with an opening at one end and an end cover which covers the opening of the shell, wherein a main shaft is fixedly arranged in the shell; the main shaft is sequentially sleeved with a pallet wheel, a rope reeling wheel, a coil spring and a ratchet wheel; a pallet fork is arranged on a position, corresponding to the pallet wheel, in the shell; the end surface of one side, close to the pallet wheel, of the rope reeling wheel is provided with an centrifugal fling block and a fling block spring which are connected; the end surface of the other side of the rope reeling wheel is provided with a dented concave table; the coil spring is embedded in the concave table; the rope reeling wheel is wound with a rope; one end of the rope is fixed on the rope reeling wheel, and the other end extends out of the shell; a pallet is arranged on a position, corresponding to the ratchet wheel, in the shell; the pallet is connected with a pallet spring in the shell; and the pallet is further provided with a multifunctional button which extends out of the shell. By using the multifunctional firefighter lifesaving device, self-saving and escaping of a firefighter can be realized during a task.

Description

technical field [0001] The invention relates to the field of firefighting equipment, in particular to a multifunctional lifesaving device for firefighters. Background technique [0002] At present, firefighters’ lifesaving ropes are generally carried in a winding manner. When using them, they need to untie the ropes in the winding state, and perform operations such as knotting according to the required length or use method, and the operation efficiency is low; this type of rope is prone to occur between multiple ropes Knots between them will affect the use; the rope needs to be rewound after use, which is extremely inconvenient. Many inconvenient factors cause fire-fighting life-saving ropes to have a low utilization rate in disaster rescue. When running into an emergency, it is not convenient to use this type of life-saving rope to avoid danger quickly. Contents of the invention [0003] The object of the present invention is to address the above problems and provide a m...
