Embodiment
Now by reference to the accompanying drawings, preferred embodiment of the present utility model is elaborated.
Embodiment one
As shown in Figure 1, 2, the anti-rotation telescopic bar of the present embodiment comprises the hollow slip joint of the coaxial socket of at least two joints, described slip joint is equipped with anti-rotation groove 13, and the anti-rotation groove 13 of adjacent expansion joint engages mutually, the rear end of the last slip joint 11 in any two adjacent slip joints is fixed with a tail plug 14, after described tail plug 14 close-fitting is arranged in a slip joint 12, which is provided with a guide groove 141 matched with the anti-rotation groove 13 of a described rear slip joint 12.Described anti-rotation groove preferably has the groove of fairing ace, and certainly, it also can be the groove of other form.Described slip joint can adopt carbon fibre material, metallic material, alloy material or plastics etc. to make, and described tail plug 14 can adopt the material such as plastics, rubber to make.Described guide groove 141 can be tail plug 14 and described moving axially of last slip joint 11 provides guiding.In the present embodiment, described slip joint is aluminum pipe, and tail plug 14 is plastic plug.Described tail plug 14 and the means of fixation of slip joint can be integral type and arrange, are threaded or the any-mode such as tackiness agent is bonding.When pulling described last slip joint 11, described tail plug 14 synchronously slides axially together with slip joint fixing with it, the setting of described anti-rotation groove 13 can prevent, between adjacent expansion joint, circumference occurs and rotate, when stopping drag described last slip joint 11, because tail plug 14 and slip joint 12 close-fitting are thereafter arranged, flexible rod is axially located.
As in Figure 2-4, the rear end of the last slip joint 11 in any two adjacent slip joints of the present embodiment is provided with annular projection district 111, the front end of a rear slip joint 12 comprises a limiting area 121, and the aperture of described limiting area 121 is less than the maximum diameter in described annular projection district 111.When described last slip joint 11 is stretched to limit position, annular projection district 111 will stop mutually with described limiting area 121, prevent the slip joint fixed with described tail plug 14 to be drawn out.Concrete, after described, the aperture of the limiting area 121 of the front end of a slip joint 12 reduces gradually along its front opening direction, and least significant end aperture is minimum-value aperture.Described annular projection district 111 is around the outer wall projection (except anti-rotation groove place) of described last slip joint 11, and its maximum diameter is the distance in the middle part of annular projection district 111 on outer wall between two symmetric points.Ensure that the described least significant end aperture distance be less than in the middle part of described annular projection district 111 on outer wall between two symmetric points just can prevent described last slip joint 11 to be drawn out.Certainly, for ensure described last slip joint 11 can sheathed enter described after in a slip joint 12, and can move axially in a slip joint 12 in the rear, after described, the minimum-value aperture of the limiting area 121 of a slip joint 12 should be greater than the external diameter of described last slip joint 11 except ring-type convex area 111.
As in Figure 3-5, at least one joint slip joint of the described anti-rotation telescopic bar of the present embodiment is provided with the ventilating hole 15 with extraneous conducting, and described tail plug 14 is provided with a through hole 144, and described through hole 144 is by a described rear slip joint 12 and last slip joint 11 mutual conduction.The inner space of flexible rod and the external world can be conducted with the through hole 144 on tail plug 14 by described ventilating hole 15, the pressure of flexible rod inner space and free surrounding space is consistent, be beneficial to stretch smoothly or compression flexible rod.Further, the end of described tail plug 14 is also provided with elastic groove 142, the setting of described elastic groove 142 can be tail plug 14 after being fitted in a slip joint 12 time elastic space is provided, simultaneously after tail plug 14 engagement sleeves is placed in a slip joint 12 in after guarantee tail plug 14 and the close-fitting effect of a rear slip joint 12, prevent from arbitrarily moving around between adjacent expansion joint.Further, the outer wall of described tail plug 14 is provided with a plane of inclination be made up of the toroidal surface of different-diameter 143, and described plane of inclination 143 is mated the slip joint close-fitting setting be nested with in the toroidal surface position of its maximum diameter, be mated by the toroidal surface position of described maximum diameter the slip joint close-fitting be nested with and the area of contact decreasing tail plug 14 and described slip joint is set, be conducive to pulling back and forth between adjacent expansion joint.
Should be understood that, above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit, for a person skilled in the art, technological scheme described in above-described embodiment can be modified, or equivalent replacement is carried out to wherein portion of techniques feature; And all such modifications and replacement, all should belong to the protection domain of the utility model claims.
