[embodiment]
In order to make the technological scheme of this patent and technique effect clearly, be described in detail below in conjunction with the embodiment of drawings and Examples to this patent.
Embodiment one:
As Fig. 1 to 8, the more piece carbon fiber flexible rod in the present embodiment, for two section telescopic bars, comprises the first bar 1, second bar 2 and the first joint 3, first locating stud 4.First joint 3 is located between the first bar 1 and the second bar 2.
In a tubular form, one end is provided with ring-type first limited ring 11 of outstanding inner tube wall to first bar 1, and the axial uniform intervals of inner tube wall is provided with the first convex tendon 12.
In a tubular form, one end is provided with ring-type second limited ring 21 of outstanding inner tube wall to second bar 2, the relative the other end be provided with match with the first locating stud 4 profile the first pin-and-hole 22, the axial uniform intervals of inner tube wall is provided with the second convex tendon 23.Second bar 2 structure is roughly the same with the first bar 1 structure, and difference is that its external diameter is not more than the internal diameter of the first bar 1.
First joint 3 comprises cylindrical and coaxial tight lock part 31 and fixing part 32.The external diameter of tight lock part 31 is identical with the first bar 1 internal diameter, and side axial is provided with first groove 311, first groove 311 suitable with the first convex tendon 12 profile and runs through bottom surface on tight lock part 31; Tight lock part 31 side is provided with the upper bottom surface that second groove 312, second groove 312 suitable with the first convex tendon 12 does not run through tight lock part 31 between two adjacent the first grooves 311.The external diameter of fixing part 32 is identical with the second bar 2 internal diameter, its axle center place is provided with vent 321, radial direction is provided with the second pin-and-hole 322 matched with locating stud 4 profile, fixing part 32 side axial is provided with three groove 323, three groove 323 suitable with the second convex tendon 23 and runs through bottom surface on fixing part 32.
Fixing part 32 the 3rd groove 323 is aimed at the second convex tendon 23, the second bar 2 is inserted in the face of the second bar 2 one end not with the second limited ring 21, first joint 3 and the second bar 2 can be fixed through the first pin-and-hole 22 and the second pin-and-hole 322, first locating stud 4 by the first locating stud 4; So by the second bar 2 with one end of the second limited ring 21 in the face of the first bar 1 one end not with the first groove 11, second groove 311 of tight lock part 31 is aimed at the first convex tendon 12 simultaneously, second bar 2 is inserted the first bar 1, adjust the position of the second bar 2 in the first bar 1 behind target location, clockwise or be rotated counterclockwise tight lock part 31, until the first convex tendon 12 slips in the 3rd groove 312, the locking of the second bar 2 and the first bar 1 can be realized.Because the second bar 2 external diameter is not more than the first bar 1 internal diameter, therefore while locking, can exert oneself to pull the second bar 2 up and down, realize the adjustment of the second bar 2 and the first bar 1 total length; But when the second bar 2 moves to the first limited ring 11 place, the second bar 2 is spacing by the first limited ring 11, can not move forward in case the second bar 2 departs from the first bar 1, second bar 2, now the length of multistage carbon fiber flexible rod is the longest again.The vent 321 of fixing part 32 is arranged, avoid the second bar 2 and produce cylinder vacuum effect in the first bar 1 movement process, in the pipe that first bar 1 and the second bar 2 are overlapped, the air pressure in space is consistent with external pressure, conveniently can be easy to rotation second bar 2 or the adjustment position of the second bar 2 in the first bar 1.
The glue that can also adopt of the first joint 3 fixing part 31 and the second bar 2 achieves a fixed connection.
When the more piece carbon fiber flexible rod in the present embodiment is more than two joints, only need add in the first bar 1 one end not with the first limited ring 11 and the second joint that the first bar 1 mates and the second locating stud, and and the 3rd bar of the second joint tight lock part coupling; Or add in the second bar 2 one end with the second limited ring 21 with second bar 2 mate the 4th joint, and and the 4th joint fixing part coupling the 4th bar.So can constantly add the quantity of bar and the quantity of joint, realize the increase of more piece carbon fiber flexible rod total length.The Telescopic rod structure of this structure visible is simple, highly versatile, and the position location of adjacent two bars can arbitrarily set, and location between two pipes, locking and unlocking operation are convenient; By the connection of convex tendon and joint tight lock part groove between adjacent two poles, and there is frictional force in a section rod tube inwall and another section rod tube outer wall, makes to there will not be between adjacent two poles to relatively rotate or slide up and down.And every pole carbon fiber is made, and has quality light, erosion-resisting advantage.
The foregoing is only the preferred embodiment of this patent, be not limited to this patent, for a person skilled in the art, this patent can have various modifications and variations.Within all spirit at this patent and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in this patent.
