Described slide block upper surface is provided with first inclined-plane, described control piece can move up and down, its lower surface parallels with described first inclined-plane is provided with second inclined-plane, described first inclined-plane is adjacent to mutually with second inclined-plane, when the described locking device release of needs, push described control piece, second inclined-plane of the described relatively control piece in first inclined-plane of described slide block slides, make the dead slot of described slide block lower surface slide into described lock dog top, but described outer tube and interior pipe slide relative; When the described locking device of needs locks, unclamp described control piece, described lock dog is positioned at described locating slot, and the lower surface of described briquetting is pushed down described lock dog, described outer tube and interior pipe relative fixed.
Preferably, offer guiding groove on the described outer wall of inner tube, described locating slot is arranged in the described guiding groove.
Preferably, described fixing device is embedded on the described outer tube wall, and it comprises lining and gib block, offer on the described lining porose, described lock dog have all the time the part be positioned at described hole, described gib block is arranged in the described guiding groove.
Further preferably, described lining is wholely set mutually with gib block.
Preferably, described control piece is set to button, and described button outer installment has button cover, and described button cover is fixed on the described outer tube.
Preferably, described lock dog is set to spherical.
Preferably, described Returnning spring one end and described button cover are fixedly connected, and the other end of described Returnning spring and described slide block are fixedly connected.
Because technique scheme utilization, the present invention compared with prior art has following advantage and effect: the locking device that telescopic pipe of the present invention adopts button to slide by upper and lower inclined-plane, the button that only need hold on the pipe when operating is stretched, is contracted, need not to consider the push-and-pull direction of button, not only easy to use, and simple in structure.

Wherein: 1, interior pipe; 2, outer tube; 3, fixing device; 4, locking device; 5, locating slot; 6, lock dog; 7, slide block; 8, dead slot; 9, first inclined-plane; 10, second inclined-plane; 11, Returnning spring; 12, guiding groove; 13, lining; 14, hole; 15, button cover, 16, seal ring; 17, button.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
A kind of as shown in Figure 1, 2 telescopic pipe, pipe 1 in comprising, slidably be set in pipe 1 outside outer tube 2, be used to prevent that outer tube 2 internally manages 1 fixing device 3 of rotating mutually, is used for outer tube 2 is internally managed the 1 axial locking device 4 of locking mutually.
Interior pipe 1 outer wall has at least 2 locating slots 5 along its axially-aligned, and the number of locating slot 5 and arrangement pitches are because of the demand setting of collapsing length.Offer guiding groove 12 on interior pipe 1 outer wall, locating slot 5 is arranged in the guiding groove 12.
Fixing device 3 comprises lining 13 and gib block, offer porose 14 on the lining 13, lining 13 is arranged between the lower surface of lock dog 6 and slide block 7, no matter for locking state or released state, lock dog has part to be positioned at hole 14 all the time, gib block is arranged in the guiding groove 12, and in the present embodiment, lining 13 is wholely set mutually with gib block.
Locking device 4 comprises the lock dog 6 that matches with locating slot 5, be used to push down lock dog 6 make its slide block that is in the lock state 7, with the button 17 that slide block 7 is in transmission connection mutually, slide block 7 lower surfaces offer dead slot 8, button 17 only can move up and down.Button 17 outer installment have button cover 15, and button cover 15 is fixed on the outer tube 2.Lock dog 6 is set to spherical.
Slide block 7 upper surfaces are provided with first inclined-plane 9, and button 17 lower surfaces parallel with first inclined-plane 9 is provided with second inclined-plane 10, and slide block 7 is connected with Returnning spring 11.Returnning spring 11 1 ends and button cover 15 are fixedly connected, and the other end of Returnning spring 11 and slide block 7 are fixedly connected.
Below the concrete concrete operation method of present embodiment down of setting forth:
When lock state, lock dog 6 is fastened in the locating slot 5, and the lower surface of slide block 7 is pressed on the lock dog 6, and at this moment, outer tube 2 is internally managed 1 mutually and can not be moved, and the length of telescopic pipe is fixed.
When needs are regulated the length of telescopic pipe, pressing button 17, button 17 presses down, and first inclined-plane 9 on the slide block 7 slides along second inclined-plane 10 on the button 17.When the dead slot 8 of slide block 7 lower surfaces moves to the top of lock dog 6, the locking device release, as shown in Figure 3.At this moment, outer tube 2 can move along interior pipe 1, as shown in Figure 4.According to the position difference of locating slot 5 on the interior pipe 1, the length of regulating telescopic pipe successively.
After lock dog 6 is positioned at selected locating slot 5, release button 17, slide block 7 resets under the elastic force of Returnning spring 11, when the lower surface of slide block 7 is pushed down lock dog 6 once more, the locking device locking, at this moment, outer tube 2 is internally managed 1 mutually and can not be moved, and the length of telescopic pipe is fixed.
Therefore, the telescopic pipe of push button only needs pressing button just can stretch to telescopic pipe, easy to operate, structure simplifies, easy to make, changed in the past because locking device structure problem and must strengthen the shape not attractive in appearance of caliber in various degree at the locking position and enlarging is easy to crack, scrap is many unfavorable factor.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
