Embodiment
Telescopic pipe of the present utility model comprises the flexible unit pipe connecting of at least two joints, and this unit pipe is aluminum pipe or Stainless Steel Tube, can be that square tube can be also pipe.As depicted in figs. 1 and 2, in the present embodiment, explain as example take unit pipe A2 and unit pipe B3, between described unit pipe A2 and unit pipe B3, lock by locking mechanism 1.
As shown in Figure 3, described locking mechanism 1 comprises locking bed 10, described locking bed 10 comprises the sleeve part 101 that is nested in unit pipe front end, described unit pipe front end side wall is provided with notch 201, the corresponding notch 201 of described sleeve part 101 is provided with through hole 103, in described through hole 103, be provided with a compact heap 11, compact heap 11 compresses inner unit pipe by notch 201.The hinged clinching 12 of described sleeve part 101 peripheral side, described clinching 12 comprises handle part 121 and is located at the compressed part 120 of handle part head end, described compressed part 120 is hinged on compact heap 11 outsides, described compressed part 120 cross sections are circular arc, and described compressed part 120 articulating points are positioned at compressed part cross section eccentric position.Locking mechanism is located at unit pipe A2 front end, and unit pipe B3 is flexible in unit pipe A2, drive compact heap 11 that unit pipe B3 is compressed by clinching 12, because compressed part 120 adopts eccentric circle structure, when clinching 12 is during in tightening state, compact heap 11 holds out against the unit pipe A2 that is positioned at unit pipe B3 makes it can not easy on and off activity.
Described unit pipe is flat tube 20, and the cross-sectional profiles of described flat tube is made up of the long limit 203 of two circular arcs and two circular arc minor faces 204, and the relative pipe of flat tube, owing to can having larger area of contact between compact heap and flat tube side, is more easily locked.To the structure of flat tube, described compact heap 11 is rhs-structure, described square tube two parallel sides outer side walls respectively corresponding unit pipe circular arc minor face 204 side arc surfaces and compressed part arc surface are provided with interior concaved circular cambered surface 110, and described handle part 121 tail ends are provided with circular arc warping part 1210 and break into two with one's hands to facilitate.
As shown in Figure 4, described unit pipe rear end is provided with positioning block 22, and described unit pipe front end is provided with baffle plate 21.In the time that flexible rod is pulled to maximum height, the positioning block of unit pipe A2 is blocked by the baffle plate of unit pipe B3, thereby can guarantee that two joint unit pipe do not disconnect.Described baffle plate 21 comprises annular flange portion 210 and is positioned at annular flange portion one end the breach ring part 211 that is provided with breach 2110, described breach ring part plug-in unit pipe front end, the setting corresponding to notch 201 of described breach 2110.Described positioning block 22 is made up of two pieces points of positioning blocks 220, described point of positioning block comprises the cover cap 2201 covering on unit pipe outer side wall and is located at cover cap and boss 2202 that unit pipe is joined on side surface, sidewall corresponding described boss in described unit pipe rear end is provided with socket 202, and described boss is by socket plug-in unit pipe.Described boss 2202 comprises cylindrical part and is distributed in two rectangular portion of cylindrical part outer circumferential sides.
As shown in Figure 5, described locking bed 10 two ends, outside are provided with hinged ear 102, and described compressed part 120 is hinged between two hinged ears 102 by a roll pin 13.
As shown in Figure 6, clinching 12 is depressed, under the effect of compressed part 120, compact heap 11 moves, thereby unit pipe is compressed, and makes it can not easy on and off activity.As shown in Figure 7, clinching 12 is broken into two with one's hands, compressed part 120 departs from the compression to compact heap 11, thereby unit pipe is discharged, and it can be stretched up and down.
