Technical field
The utility model relates to a kind of commodity, particularly relates to a kind of damped type flexible rod.
Background technique
At present, the telescopic pipe that self-shooting bar on the market uses is mostly fixing metal shell fragment and bassoon on tubule and rubs provide feel and fix, need when little bar stretches and will fix to certain position extra structure or dynamic award fixing, when this traditional structure exists flexible, not good, the metal clips of feel and bassoon arm rub and easily send the defect of allophone, use and comparatively bother.
Summary of the invention
The purpose of this utility model is to provide a kind of capable of expansion and contraction, damped type flexible rod smoothly.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of damped type flexible rod, draws together large sleeve pipe, small casing, plastic cement piston, rubber ring, only pulling block; Described rubber ring sleeve is connected on one end of plastic cement piston, and be socketed with the movable endoporus be nested with at large sleeve pipe of this end of rubber ring, the other end of plastic cement piston is fixedly nested with in one end of small casing endoporus; Described only pulling block in the form of a ring, is fixedly nested with the aperture place at large casing tube internal hole and is arranged in the outside be nested with at small casing endoporus plastic cement piston, playing and prevent plastic cement piston from deviating from large casing tube internal hole effect, and only the endoporus of pulling block passes by small casing gap.
The other end of described plastic cement piston is fixedly nested with in an interference fit in one end of small casing endoporus.
A radially protruding projection on described only pulling block outer wall, the hole wall of large sleeve pipe one end offers a through hole, it is corresponding that this hole size and the projection stopped on pulling block carry out size, only pulling block is nested with when the aperture place of large casing tube internal hole, and the projection only on pulling block outer wall inserts the through hole of large sleeve pipe one end.
Described plastic cement piston one end is provided with two annular grooves, and for being socketed two rubber rings, the other end of plastic cement piston offers two relative short slots vertically, so that it mode of resiliently deformable can insert small casing.
The cross section ovalize of described large sleeve pipe, small casing, plastic cement piston, rubber ring, only pulling block.
Described large sleeve pipe, small casing, plastic cement piston, rubber ring, the only cross section of pulling block are triangular in shape.
Described large sleeve pipe, small casing, plastic cement piston, rubber ring, the only cross section of pulling block are quadrilateral.
After adopting such scheme, socket due to the large sleeve pipe of the utility model and small casing is that the plastic cement piston by being socketed with rubber ring realizes, large internal surface of sleeve pipe coordinates with rubber ring, various noise can not be sent and coordinate level and smooth, smooth and easy, such that the utility model is capable of expansion and contraction, smooth and easy, good hand touch.The only pulling block arranged in addition effectively prevent small casing and spins off from large sleeve pipe, easy to use, reliable, and small casing can be assisted to locate in large sleeve pipe, makes small casing comparatively smooth-going in the slip of large sleeve pipe, can not rock.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Embodiment
As shown in Figure 1-Figure 3, the utility model is a kind of damped type flexible rod, comprises large sleeve pipe 1, small casing 2, plastic cement piston 3, two rubber rings 4, only pulling block 5.
Shown in composition graphs 4, Fig. 6, Fig. 7, described plastic cement piston 3 one end is provided with two annular grooves 31, for being socketed two rubber rings 4, the other end of plastic cement piston 3 offers two relative short slots 32 vertically, so as its can the mode of resiliently deformable insert small casing 2(as shown in Figure 5).
Two described rubber rings 4 are socketed on two annular grooves 31 of plastic cement piston 3 one end respectively, be socketed with the movable endoporus be nested with at large sleeve pipe 1 of this end of rubber ring 4, the other end of plastic cement piston 3 is fixedly nested with in an interference fit in one end of small casing 2 endoporus, when being inserted in, the short slot 32 on plastic cement piston 3 can produce resiliently deformable.
Shown in composition graphs 8, described only pulling block 5 in the form of a ring, fixedly be nested with at the aperture place of large sleeve pipe 1 endoporus and be arranged in the outside be nested with at small casing 2 endoporus plastic cement piston 3, playing and prevent plastic cement piston 3 from deviating from the effect of large sleeve pipe 1 endoporus, only the endoporus of pulling block 5 passes by small casing gap.In the present embodiment, only pulling block 5 with the secure fit mode of large sleeve pipe 1 is: a radially protruding projection 51 on only pulling block 5 outer wall, the hole wall of large sleeve pipe 1 one end offers a through hole 1, it is corresponding that this through hole 11 size and the projection 51 stopped on pulling block 5 carry out size, only pulling block 5 is nested with when the aperture place of large sleeve pipe 1 endoporus, and the projection 51 only on pulling block 5 outer wall inserts the through hole 11 of large sleeve pipe 1 one end.
