Carbon fiber composite telescopic pipe and manufacturing method thereof

Abstract

The invention discloses a carbon fiber composite telescopic pipe and a manufacturing method thereof, and relates to the technical field of telescopic pipes. The carbon fiber composite telescopic pipe comprises a plurality of sections of sleeves which are sequentially arranged in a telescopic mode, the outer diameter of each section of sleeve is gradually reduced from outside to inside, a locking mechanism is arranged between every two adjacent sections of sleeves, and the locking mechanisms are used for achieving locking and retreating prevention when every two adjacent sections of sleeves stretch out. According to the carbon fiber composite telescopic pipe and manufacturing method thereof, the multi-section telescopic sleeves is adopted, the inner side sleeves can stretch out at any angle, locking is firm, unlocking is convenient, using safety is high, the multi-section sleeves are made of a novel carbon fiber composite material and is high in strength, light in weight and wide in using range.

Description

technical field [0001] The invention relates to the technical field of telescopic tubes, in particular to a carbon fiber composite material telescopic tube and a manufacturing method thereof. Background technique [0002] The telescopic tube is used in many fields because its length can be changed, such as inspection and testing equipment, impression photography equipment, outdoor sporting goods, cleaning tools, etc. The user stretches out a certain length when it needs to be used, and shrinks it when not in use. Back, because of its small size, easy to carry, and flexible use, the telescopic tube is often used as a telescopic baton in police equipment. It is a common tool for fighting crime and defending the user's own safety. At the same time, it is necessary to lock each section of the casing to prevent the telescopic pipe from being stretched out into a retracted state during use, which will seriously affect the user and even endanger personal safety. At present, the com...

b class="d_n">[0002] The telescopic tube is used in many fields because its length can be changed, such as inspection and testing equipment, impression photographic equipment, outdoor sporting goods, cleaning tools, etc., and the user stretches it when needed Extend a certain length and retract when not in use. Because of its small size, easy to carry, and flexible use, the telescopic tube is often used as a telescopic baton in police equipment to fight crime and defend the user himself. It is a safe common tool. When the telescopic tube is extended, each section of the casing needs to be locked to prevent the telescopic tube from extending from the extended state to the retracted state during use, which will seriously affect the user and even endanger personal safety. At present, the commonly used locking mechanism for telescopic tubes is the pinball type. Holes are drilled at appropriate positions at the front and rear ends of the adjacent sleeves in the same direction, and the pinballs are built in. After the sleeve is stretched in place, the pinballs snap into the holes to realize the lock Locking, in order to ensure that the marble can be accurately inserted into the hole, matching grooves and protrusions need to be processed on the adjacent sleeves for guidance. The telescopic tube can only expand and contract according to the guide. It is easy to be stuck, complex in structure, inconvenient to operate, and low in precision. In addition, commonly used telescopic tubes are made of steel pipes, which are heavy and consume physical energy of the user for carrying and use, resulting in low work efficiency.
