[detailed description of the invention]
In order to make technical scheme and the technique effect of this patent clearer, below in conjunction with accompanying drawing andEmbodiment is described in detail the detailed description of the invention of this patent.
Embodiment mono-:
As Fig. 1 to 8, the more piece carbon fiber expansion link in the present embodiment, taking two section telescopic bars as example,Comprise the first bar 1, the second bar 2 and the first joint 3, the first alignment pins 4. The first joint 3 is located atBetween one bar 1 and the second bar 2.
In a tubular form, one end is provided with ring-type first spacing ring 11 of outstanding inside pipe wall to the first bar 1, pipeInwall is axially evenly interval with the first convex tendon 12.
In a tubular form, one end is provided with ring-type second spacing ring 21 of outstanding inside pipe wall, phase to the second bar 2The right other end be provided with the first alignment pin 4 profiles match the first pin-and-hole 22, inside pipe wall is axialEvenly be interval with the second convex tendon 23. The second bar 2 structures and the first bar 1 structure are roughly the same, differencePart is that its external diameter is not more than the internal diameter of the first bar 1.
The first joint 3 comprises cylindrical and coaxial tight lock part 31 and fixed part 32. Tight lock part31 external diameter is identical with the first bar 1 internal diameter, and side axial is provided with the first convex tendon 12 profiles suitableThe first groove 311, the first grooves 311 run through bottom surface on tight lock part 31; Tight lock part 31 sides are twoBetween individual the first adjacent groove 311, be provided with second groove 312, the suitable with the first convex tendon 12Two grooves 312 do not run through the upper bottom surface of tight lock part 31. In the external diameter of fixed part 32 and the second bar 2Footpath is identical, and its axle center place is provided with passage 321, be radially provided with alignment pin 4 profiles match secondPin-and-hole 322, fixed part 32 side axial are provided with three groove 323 suitable with the second convex tendon 23,The 3rd groove 323 runs through bottom surface on fixed part 32.
Fixed part 32 the 3rd groove 323 is aimed to the second convex tendon 23, in the face of the second bar 2 is not with theThe second bar 2, the first alignment pins 4 are inserted through the first pin-and-hole 22 and the second pin in one end of two spacing rings 21Hole 322, the first alignment pins 4 can be by fixing to the first joint 3 and the second bar 2; So the second bar 2 is withThere is one end of the second spacing ring 21 in the face of not one end with the first groove 11 of the first bar 1, will lock simultaneouslyThe second groove 311 of tight portion 31 is aimed at the first convex tendon 12, and the second bar 2 is inserted to the first bar 1, adjustsThe position of the second bar 2 in the first bar 1 is behind target location, clockwise or be rotated counterclockwise lockingPortion 31, until the first convex tendon 12 slips in the 3rd groove 312, can realize the second bar 2 and the first bar1 locking. Because the second bar 2 external diameters are not more than the first bar 1 internal diameter, therefore locking in, canFirmly pull up and down the second bar 2, realize the adjustment of the second bar 2 and the first bar 1 total length; But the second bar2 while moving to the first spacing ring 11 place, and the second bar 2 is spacing by the first spacing ring 11, in case the second bar2 depart from the first bar 1, the second bar 2 can not move forward again, the now length of multistage carbon fiber expansion linkSpend the longest. The passage 321 of fixed part 32 arranges, and has avoided the second bar 2 to move at the first bar 1In journey, produce cylinder vacuum effect, make the air pressure in space in pipe that the first bar 1 and the second bar 2 overlapConsistent with external pressure, can conveniently be easy to rotate the second bar 2 or adjust the second bar 2 at the first bar 1In position.
The glue that can also adopt of the first joint 3 fixed parts 31 and the second bar 2 achieves a fixed connection.
When the more piece carbon fiber expansion link in the present embodiment is during more than two joints, only need be at the first bar 1Do not append with one end of the first spacing ring 11 the second joint and the second alignment pin that mate with the first bar 1,And and the 3rd bar of the second joint tight lock part coupling; Or at the second bar 2 with the second spacing ring 21The 4th joint mating with the second bar 2 is appended in one end, and and the 4th joint fixed part coupling the 4thBar. So can constantly append the quantity of bar and the quantity of joint, realize more piece carbon fiber expansion link overall lengthThe increase of degree. The Telescopic rod structure of visible this structure is simple, highly versatile, the location of adjacent two barsPosition can arbitrarily be set, and location between two pipes, locking and unlocking operation are convenient; Adjacent two jointsBetween bar by the connection of convex tendon and joint tight lock part groove, and a section rod tube inwall and another polePipe outer wall there is frictional force, make to there will not be and relatively rotate or slide up and down between adjacent two poles.And every pole is made with carbon fiber, has quality light, erosion-resisting advantage.
The preferred embodiment that the foregoing is only this patent, is not limited to this patent,For a person skilled in the art, this patent can have various modifications and variations. All at this patentSpirit and principle within, any amendment of doing, be equal to replacement, improvement etc., all should be included in thisWithin the protection domain of patent.
