[specific embodiment]
It is described in further detail with reference to the accompanying drawing with the embodiments of the present invention:
As shown in Figs 1-4, a kind of pressure expansion self-locking structural casing includes outer tube 1 and in can sliding in outer tube 1
Pipe 2,1 socket end of outer tube are connected with clamping sleeve 3, resilient sleeve 4 are equipped in the clamping sleeve 3, and the resilient sleeve 4 is equipped with outer cone
Face 5, the clamping sleeve 3 is interior to be equipped with the outer inclined-plane 6 cooperated with male cone (strobilus masculinus) 5, is equipped with slidable inner tube 2, institute in the resilient sleeve 4
It states inner tube 2 and is equipped with the card 7 for preventing resilient sleeve 4 from skidding off, the phase between clamping sleeve 3 is socketed with outside the clamping sleeve 3 and resilient sleeve 4
The installation set 8 mutually slided, the installation set 8 are connected with plug 9, and the clamping sleeve 3 is equipped with for pushing clamping sleeve 3 to compress bullet
Property set 4 realize the springs 10 of inner tubes 2 and 1 locking of outer tube, described 10 one end of spring connect with clamping sleeve 3, and the spring 10 is another
End is connect with plug 9, wherein the clamping sleeve 3 is fixedly connected with outer tube 1.
When stretching, it need to only pull and pull outer tube 1 and inner tube 2 to user demand length respectively, in drawing process, outside
It is mobile that pipe 1 drives clamping sleeve 3, and compresses the spring 10 between clamping sleeve 3 and plug 9, at this time the outer inclined-plane 6 and bullet of clamping sleeve 3
Property set 4 male cone (strobilus masculinus) 5 be staggered, frictional force between resilient sleeve 4 and inner tube 2 is reduced, so that inner tube 2 is with stretching and in resilient sleeve 4
Slidable adjustment length stops drag outer tube 1 and inner tube 2 when length adjustment is completed, spring 10 resets, and clamping sleeve 3 is pushed to press
Tight resilient sleeve 4,3 outer inclined-plane 6 of clamping sleeve presses the male cone (strobilus masculinus) 5 of resilient sleeve 4 at this time, and resilient sleeve 4 is made to press inner tube 2, increases elasticity
Frictional force between set 4 and inner tube 2 realizes that the locking between outer tube 1 and inner tube 2 is fixed.
Similarly, when contraction, it need to only hold outer tube 1 and press plug 9, outer tube 1 pull clamping sleeve 3 and compressed spring 10, this
When clamping sleeve 3 outer inclined-plane 6 and the male cone (strobilus masculinus) 5 of resilient sleeve 4 be staggered, frictional force between resilient sleeve 4 and inner tube 2 is reduced, so that interior
Pipe 2 can slide to be retracted in outer tube 1 in resilient sleeve 4, and the press of plug 9 is unclamped after the completion of shrinking.
Wherein, when outer tube 1 and inner tube 2 slide into maximum length, card 7 stops inner tube 2 to be slided, and inner tube 2 is prevented to be detached from.
As shown in Figure 1, only need to press plug 9 for the first time when being equipped with multistage pressure expansion self-locking structure, work as first segment
After the completion of contraction, the plug 9 of the second stage pressure expansion self-locking structure is contacted with the installation set 8 of the first stage pressure expansion self-locking structure
And first order installation set 8 is made to press second level plug 9, realize the outer inclined-plane 6 of clamping sleeve 3 in the second stage pressure expansion self-locking structure
It is staggered with the male cone (strobilus masculinus) 5 of resilient sleeve 4, realizes the contraction of the second section.
The clamping sleeve 3 is equipped with clamping sleeve edge 11, and described 10 one end of spring is connect with clamping sleeve edge 11, convenient for pressure
Contracting spring 10.
The resilient sleeve 4 is equipped with resilient sleeve card slot 12, is equipped with and resilient sleeve card slot 12, the peace in the installation set 8
It is equipped with the installation set edge 13 engaged with resilient sleeve card slot 12 in encapsulation 8, resilient sleeve 4 is prevented to be detached from installation set 8.
It is threadedly coupled between the installation set 8 and plug 9, connection structure is simply firm.
Said inner tube 2 is equipped with card hole 14, and the card 7 is equipped with the fixture block 15 engaged with card hole 14, preferably fixed
Fixture block 15 is to prevent inner tube 2 to be detached from, the limit raised line 16 equipped with the setting of elongatedness direction in the outer tube 1, and the card 7 is
Two pieces, the limit raised line 16 is arranged in the sliding slot of two cards 7 composition.
Wherein, there are three functions for the tool of card 7, first is that card 7 is fastened in the card hole 14 of inner tube 2, is symmetrical two panels, prevents
Inner tube 2 is completely pulled out from outer tube 1, when shrink it is shortest when resilient sleeve 4 it is farthest at a distance from card 7, when stretching longest, bullet
Property set 4 be in contact with card 7, more multiple-length can not be pulled out, this when, inner tube 2 was similarly also in outer tube 1；Second is that two panels card
Piece 7 symmetrically uses, and forms sliding slot between two panels card 7, and the limit raised line 16 in outer tube 1 is sliding in the sliding slot that two cards 7 form
It is dynamic, it prevents that mutually rotation occurs between inner tube 2 and outer tube 1；Third is that card 7 prevents inner tube 2 to be completely pulled out, when being connected to maximum distance
Inner tube 2 and outer tube 1 have certain crossing length, and card 7,2 outer diameter of inner tube are in contact with 1 internal diameter of outer tube, reduce outer tube 1 and inner tube
Curvature between 2.It keeps outer tube 1 and inner tube 2 is concentric parallel.
