Abstract
The utility model relates to a telescopic suction pipe. The utility model comprises an outer pipe, an inner pipe and a locking mechanism, wherein the locking mechanism comprises a containing groove which is axially arranged on the outer surface of the inner pipe, a locking sheet which is embedded in the containing groove and stopping pins which are arranged on the outer pipe in a slide way, and a plurality of stopping holes are arranged on the locking sheet. When the locking mechanism is in a locking state, each stopping pin is inserted in each stopping hole, when the locking mechanism is in an unlocking state, each stopping pin breaks away from each stopping hole. The inner pipe and the outer pipe can be locked axially by matching the stopping pins with the locking holes on the locking sheet, and a liner pipe does not need arranging additionally. Namely, the inner pipe is a single-layer pipe, production materials are saved, and the telescopic suction pipe has convenient assembly.
Description
Technical field
The utility model relates to a kind of telescopic sucking tube that is applied to usually on the dust catcher.
Background technology
In the prior art, telescopic sucking tube on the dust catcher comprises outer tube, be inserted in the interior pipe in the outer tube slidably, between outer tube and interior pipe, be provided with locking mechanism, this locking mechanism comprises the lock hole of the axially-aligned of pipe in the edge of opening on inner pipe, be arranged at the latch on the outer tube, latch can insert in the lock hole so that outer tube and interior pipe are locked along radially sliding of outer tube, because the wall portion of pipe in each lock hole penetrates, so in the inner chamber of interior pipe, also be fixed with bushing pipe, with the sealing property of assurance suction pipe, but this method of establishing bushing pipe has in addition caused the waste of producing material.
Summary of the invention
The utility model purpose provides a kind of telescopic sucking tube, and it can be set to the individual layer body by interior pipe.
For achieving the above object, the technical solution adopted in the utility model is: a kind of telescopic sucking tube, comprise outer tube, slidably be inserted in interior pipe in the inner chamber of described outer tube, be used for being provided with the pilot bushing that slides vertically in order to the relative outer tube of guiding inner tube in the described outer tube at the axial locking mechanism of described outer tube of locking and interior pipe.Described locking mechanism comprise be arranged at vertically on the outer surface of pipe accepting groove, be embedded in locking plate in the described accepting groove, can radially be arranged at the latch on the described outer tube slidably, have the stop hole of the axially-aligned of pipe in a plurality of edges on the described locking plate, when described locking mechanism is in the lock state, described latch is inserted in the stop hole, when described locking mechanism was in released state, described latch broke away from stop hole.
Have the radially guiding convex tendon of projection on the inner surface of described pilot bushing, described guiding convex tendon is inserted in the accepting groove of locking plate top.
Has a segment distance between the lower surface of described locking plate and the groove bottom of accepting groove.
The two side of described accepting groove has locating slot vertically, and the dual-side portion of described locking plate is inserted in respectively in two locating slots.
Be connected with shift fork on the described latch rotationally, described shift fork is positioned at the outside of outer tube.
Because technique scheme utilization, the utility model compared with prior art has following advantage: the accepting groove that extends vertically is set on inner tube outer surface, and the locking plate have lock hole is set in accepting groove, by latch with cooperating of lock hole make that inner and outer pipes can be axially locked on the locking plate, this just need not to establish in addition bushing pipe, pipe had both been saved the production material for mono-layer tube promptly, made the easy to assembly of this telescopic sucking tube again.

The specific embodiment
Referring to accompanying drawing 1-accompanying drawing 4, a kind of telescopic sucking tube, comprise outer tube 2, slidably be inserted in interior pipe 1 in the inner chamber of described outer tube 2, be used at the axial described outer tube 2 of locking locking mechanism with interior pipe 1.Described locking mechanism comprise be arranged at vertically on pipe 1 the outer surface accepting groove 4, be embedded in locking plate 3 in the described accepting groove 4, can radially be arranged at the latch 11 on the described outer tube 2 slidably, have the stop hole 5 of the axially-aligned of pipe 1 in a plurality of edges on the described locking plate 3, when described locking mechanism is in the lock state, described latch 11 is inserted in the stop hole 5, when described locking mechanism was in released state, described latch 11 broke away from stop hole 5.
Be connected with shift fork 7 rotationally on the described latch 11, described shift fork 7 is positioned at the outside of outer tube 2.Described outer tube 2 is provided with shift fork seat 9, and the middle part of described shift fork 7 is positioned on the shift fork seat 9 rotationally.Be covered with top cover 6 in the outside of shift fork seat 9, be provided with reseting pressuring spring 12 between described latch 11 and the top cover 6.
The end of shift fork 7 has button 8, and this button 8 is positioned at the outside of top cover 6.Shown in accompanying drawing 3, push button 8, shift fork 7 moves in the direction of the clock, and the tension force that makes latch 11 overcome reseting pressuring spring 12 moves upward and breaks away from stop hole 5, and outer tube 2 axially can slide relatively with interior pipe 1; Shown in accompanying drawing 2, behind the release button 8, latch 11 is subjected to the tension force effect of reseting pressuring spring 12 and moves downward in the back reeve stop hole 5, and 7 of shift forks are resetting after rotating in the counterclockwise direction under the drive of latch 11, and outer tube 2 and interior pipe 1 are axially promptly locked.Shown in accompanying drawing 2-accompanying drawing 3, has a segment distance between the groove bottom of the lower surface of described locking plate 3 and accepting groove 4, when locking mechanism is in the lock state, latch 11 passes stop hole 5 backs between the groove bottom of locking plate 3 and accepting groove 4, can strengthen the reliability that latch 11 matches with stop hole 5 and locks.
