Technical Field

[0001] The utility model relates to the technical field of life-saving tools, in particular to a life-saving pull rod which is convenient for storage. Background Art

[0002] A life lever is a device commonly used in water or emergency rescue operations. It is mainly used to help people who fall into the water or are trapped in the water to save themselves or be pulled onto a safe area such as a boat or ship by rescuers. One of the most important functions of a life lever is to provide a tool to help rescuers pull people who fall into the water or are trapped to a safe area. When someone falls into the water, the life lever can allow people in the water to grab hold of them. As a simple but very effective water rescue tool, the life lever can greatly improve the success rate of rescue in an emergency and ensure the safety of people who fall into the water and rescuers.

[0003] The above utility model has the following problems:

[0004] However, the life-saving pull rods in the prior art are usually long as a whole and difficult to fold or disassemble, making it difficult to store them in a limited space, resulting in them occupying a large space when stored. In addition, the life-saving pull rods that are difficult to fold or disassemble are troublesome to carry and transport.

[0005] Therefore, those skilled in the art provide a life-saving pull rod that is convenient for storage to solve the problems raised in the above background technology. Utility Model Content

[0009] As a further solution of the present invention: the upper and lower sides of the main rod near one end are both provided with sliding grooves, the upper and lower sides of one end of the second telescopic rod are both fixedly connected with sliders, and the sliders are slidably connected to the sliding grooves.

[0010] As a further solution of the present invention: the main rod is fixedly connected to the first rack near the middle upper and lower walls, and the upper and lower sides of one end of the first telescopic rod are rotatably connected to gears.

[0011] As a further solution of the present invention: the upper and lower sides of one end of the second telescopic rod are fixedly connected to the second rack, and the gear, the second rack and the first rack are meshed and connected with each other.

[0012] As a further solution of the present invention: one end of the first telescopic rod is fixedly connected to a fixed block, the inner side of the fixed block is slidably connected to a clamping block, and the outer side of the clamping block is sleeved with an adjusting spring.

[0013] As a further solution of the present invention: the regulating spring is in an extended state by default, and a plurality of card slots are provided on one side of the second telescopic rod, and the card slots and the card blocks cooperate with each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The first telescopic rod is connected to the inside of the main rod, and the second telescopic rod is connected to the inside of the first telescopic rod, which provides good elasticity and easy storage. One end of the main rod is fixedly connected to the rescue rope, and a rescue rope winding groove is opened on the outside to store and prevent the rescue rope from sliding. The user can easily take out the rescue rope when needed. One end of the second telescopic rod is threadedly connected to the floating airbag, which can provide buoyancy in the water to prevent the lifesaving pull rod from sinking into the water. One end of the floating airbag is connected to the floating rod, which provides a grabbing point for the person who falls into the water, ensuring that the user can grab and float smoothly, so that the lifesaving pull rod has efficient storage and deployment functions, especially in emergency situations, and can be deployed quickly. The coordinated use of the rescue rope and the floating airbag improves the rescue efficiency, can ensure floating on the water, and provides a floating rod that is easy for the person who falls into the water to grab. The design of the rescue rope winding groove not only plays a storage role, but also effectively prevents the rope from sliding during use, thereby increasing the safety and convenience of operation.
