Understand for technical characteristics of the present utility model, purpose and effect being had more clearly, now contrast description of drawings embodiment of the present utility model.
See also Fig. 1 to Fig. 4, the utility model is that it includes about a kind of telescopic pipe with flow channel:
One outer tube 1 is provided with at least one positioning rib longitudinally 11 in inner edge;
One collar 2 forms a promising taper content hole, and the one end is made as the bigger class's tank 21 of opening, inserts fixingly for this outer tube 1, and it is less that the other end is made as opening, and inside is provided with a water stop ring 22, stretches for interior pipe 4 to set into;
One locked assembly 3 is mounted in the outer tube 1, comprises turn cover 31, one locking cover 32, this turn is overlapped 31 1 ends and is provided with one and places restrictions on portion 311, this is placed restrictions on portion 311 and is provided with a corresponding perforation 312, wears for a fixing-assembly 313, and this turn is overlapped 31 the other ends and is provided with an outside thread 314 outward; Be provided with an internal thread 321 in these locking cover 32 1 ends, screw togather for outside thread 314 with this turn cover 31, be provided with the support sheet 323 of a plurality of profile grooves 322 of tool in the other end body periphery, and one water stop ring 324 is arranged in these support sheet 323 upper ring caps, and locking cover 32 the other end outer rims are provided with at least one draw-in groove 325, for positioning rib 11 engagings of this outer tube 1;
Pipe 4 in one, comprise an interior tube body 41, one end forms a connecting tube 42 than path, these connecting tube 42 ends are provided with the perforation 421 of a correspondence, combine fixingly by the perforation 312 of a fixing-assembly 313 and turn cover 31, these connecting tube 42 lower edges form a cant periphery 422, can the support sheet 323 that should locking overlap 32 is outside to only strutting during pipe 4 displacements in being convenient to, and be provided with an a junction 423 and a water stop ring 424 in cant periphery 422 belows, for fixing with these interior tube body 41 leak proof engagement.
See also Fig. 1 to Fig. 3, telescopic pipe group with flow channel is established when implementing, with the joint 42 sheathed water stop rings 424 of interior pipe 4 and insert in the interior tube body 41 in conjunction with fixing, the internal thread 321 that 31 outside threads 314 and locking cover 32 are overlapped in the turn of this locked assembly 3 screws togather group mutually and establishes, water stop ring 324 is located on the outer rim of these locking cover 32 support sheets 323, after group is established it is worn the connecting tube 42 of pipe 4 in this, utilize this fixing-assembly 313 to wear this and place restrictions on perforation 312 in the portion 311, make the perforation 421 of itself and connecting tube 42 fixing, so that this locked assembly 3 combines with interior pipe 4, and the support sheet 323 of this locking cover 32 just can be located on the outer rim of these connecting tube 42 cant peripheries 422, sees also Fig. 2; Class's tank 21 of in addition outer tube 1 one ends being inserted the collar 2 is interior affixed, again the waterexit end B of interior pipe 4 is worn via the water intake end A inner edge of outer tube 1, make the positioning rib 11 of outer tube 1 just can engage the draw-in groove 325 that is positioned this locking cover 32, and be able in the inner edge of outer tube 1 sliding stretching, be positioned this collar 2 opening smaller parts until this locked assembly 3, simultaneously by the leakproof effect of this water stop ring 22, as shown in Figure 4 with pipe 4 in strengthening.
See also Fig. 5 to Fig. 7 again, when telescopic pipe of the present utility model is adjusted length, pipe 4 and outer tube 1 in hand can grip respectively, pipe 4 and 31 rotations of the cover of interlock turn synchronously in the rotation, because the turn of locked assembly 3 cover 31 screws togather group each other with locking cover 32 and establishes, and the draw-in groove 325 of locking cover 32 engages the location with the positioning rib 11 of outer tube 1, so this locking cover 32 there is no rotation phenomenon, therefore when turn cover 31 is placed restrictions on the sealed extremely locking of portion's 311 turns cover 32 upper limbs, the support sheet 323 that causing locking cover 32 is moved up by the ora terminalis of the interior tube body 41 cant periphery 422 via connecting tube 42, support sheet 323 is butted on these connecting tube 42 tube walls than path to internal condensation and answer subsides, when locked assembly 3 unclasp finish after, interior pipe 4 can overlap 32 draw-in groove 325 by locking in positioning rib 11 top offsets of outer tube 1, to obtain the displacement collapsing length of pipe 4 in this, as shown in Figure 6; And when telescopic pipe after the length of this demand, with interior pipe 4 reverse turns, the internal thread 321 turn pines that this turn cover 31 will utilize outside thread 314 and locking cover 32 from, support sheet 323 with locking cover 32 is moved down together with the cant periphery 422 of water stop ring 324 via interior pipe 4, and then its support sheet 323 is supported to arrive in to the inner edge of outer tube 1, till the inner edge of this cant periphery 422 and this outer tube 1 supports mutually admittedly, and reach the effect of leakproof, as shown in Figure 7; The utility model embodiment is for to be combined as example with interior pipe 4 and outer tube 1 double section tube body, but the also extensible combinations that are three joints or three joints with upper tube body on actual the use.
In sum, the utlity model has the telescopic pipe of flow channel, refer to a kind of turn cover and the fixed interlock of interior pipe, and this locking cover is positioned on the positioning rib of outer tube inner edge by draw-in groove, so when the rotation of interior pipe, cant periphery of pipe has the function to the action of support sheet in this, so that the support sheet has in the inner edge of the cant periphery that only supports or unclasp pipe in this and outer tube, and this locked assembly can reach flexible unclasping, according to making this telescopic pipe length displacement have high stability and the long-term effect of using.
The above only is the schematic embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
