Description

Technical Field

[0001] The utility model relates to the technical field of life-saving pull rods, in particular to a telescopic water area life-saving pull rod. Background Art

[0002] The life-saving pull rod is mainly used for water rescue. The telescopic life-saving pull rod adopts multiple telescopic joints to increase the life-saving range. The front end of the life-saving pull rod is generally connected to the ring or float through a connector to achieve life-saving.

[0003] Most of the current telescopic water rescue rods adopt a round rod structure. After the telescopic section is extended, the life-saving rod is easily deformed or broken, thereby affecting the rescue. In addition, during use, since the telescopic section can rotate on its own, the telescopic section may rotate during the rescue, causing the ring to rotate, affecting the rescue effect. Therefore, an improved technology is urgently needed to solve this problem existing in the existing technology. Utility Model Content

The inner diameter of the adjacent and outer telescopic sleeve sections 2 is consistent with the outer diameter of the limiting outer folding edge 7 at the end of the inner telescopic sleeve section 2, thereby ensuring the stability of each telescopic sleeve section 2. The inner diameter of the telescopic sleeve section 2 located at the inner end is consistent with the outer diameter of the limiting outer folding edge 7 at the end of the inner rod body 3, thereby ensuring the stability of the inner rod body 3. The other end of the telescopic sleeve section 2 is open and is provided with a second inner folding block 8. The two inner folding blocks 8 are provided with a plurality of second guide grooves 9, and a connecting head 10 is provided at the other end of the inner rod body 3.

When the front end of the inner rod body 3 passes through the telescopic sleeve section 2, screw the limiting bolt 12 into the screw hole at the front end of the inner rod body 3. Then insert the telescopic sleeve section 2 with the inner rod body 3 into the second telescopic sleeve section 2, and similarly pass the reinforcing rib 11 of the telescopic sleeve section 2 with the smallest inner diameter through the second guide groove 9 of the second telescopic sleeve section 2, and insert the limiting outer folded edge 7 at the end of the first telescopic sleeve section 2 into the second telescopic sleeve section 2. When the front end of the first telescopic sleeve section 2 passes through the second telescopic sleeve section 2, screw the limiting bolt 12 into the screw hole at the front end of the first telescopic sleeve section 2. Similarly, after all the telescopic sleeve sections 2 are plugged in one by one and limited by the limiting bolt 12, insert all the telescopic sleeve sections 2 into the main sleeve 1 from the end away from the first inner folding block 5, and pass the reinforcing rib 11 of the telescopic sleeve section 2 at the outermost end through the first guide groove 6, and insert the limiting outer folded edge 7 at the end of the outermost telescopic sleeve section 2 into the main sleeve 1. Finally, screw on the handle 4 to complete the assembly. When in use, the ring can be connected to the connector 10, the inner rod body 3 and the telescopic sleeve section 2 can be pulled out to lengthen the pull rod, and the float can be connected to the limit bolt 12 to make the front end of the pull rod float on the water surface, which is convenient for rescue. The utility model has a reasonable structure. There are multiple telescopic sleeve sections 2 and they are socketed with each other. The inner rod body 3 is inserted in the innermost telescopic sleeve section 2. All the telescopic sleeve sections 2 and the inner rod body 3 are inserted in the main sleeve 1. The telescopic sleeve section 2 and the inner rod body 3 are both provided with reinforcing ribs 11. The reinforcing ribs 11 of the outermost telescopic sleeve section 2 cooperate with the first guide groove 6 of the main sleeve 1, and the reinforcing ribs 11 on the outer surface of the inner rod body 3 and the remaining telescopic sleeve sections 2 cooperate with the second guide groove 9 of the corresponding telescopic sleeve section 2. By providing the reinforcing ribs 11, the strength of each telescopic sleeve section 2 and the inner rod body 3 is greatly improved, and the probability of fracture is reduced. In addition, by guiding and cooperating with the first guide groove 6 and the corresponding second guide groove 9, when rescuing through the ring, the situation in which the telescopic sleeve section 2 or the inner rod body 3 rotates and causes the ring to rotate can be avoided, thereby reducing the difficulty of rescue.
