Detailed description of the invention
Below in conjunction with accompanying drawing and case study on implementation, the invention will be further described:
A kind of dust collector expansion pipe as shown in Figure 1, 2, 3, comprise outer tube 1, to be arranged on outer tube 1 inner and can be along the inner tube 2 of outer tube 1 axial stretching and the lock controller for relative outer tube 1 inner tube is axially locked, wherein: inner tube 2 outer walls have several grooves 20 along its axially-aligned. Specifically:
Lock controller comprises needle roller 3, is pressed in the slide block 4 on needle roller 3 tops, as shown in Figure 5: slide block 4 has a lower surface 40, offers dead slot 41 on lower surface 40, and in the present embodiment: dead slot 41 offers two. Lock controller also comprises the lining 5 that is connected with outer tube 1, be set in outside and the control handle 6 that can be mobile vertically of lining 5. Wherein:
As shown in Figure 6: lining 5 offers tunnel 50 vertically, what slide block 4 can slide is arranged in tunnel 50; 50 bottoms, tunnel offer the needle roller hole of perforation, and needle roller 3 is arranged in needle roller hole; In lining 5, be provided with chock plug 51, chock plug 51 stops up the two ends in tunnel 50, offers extending column hole on chock plug 51.
Slide block 4 two ends have the extending column 42 extending to both sides, and extending column 42 is from offseting with controlling handle 6 through stretching out lining 5 in extending column hole, are positioned on the extending column 42 in tunnel 50 and are arranged with back-moving spring 7. In the present embodiment: control on handle 6 and there is the block reinforcement 60 offseting with extending column 42.
The concrete course of work of setting forth lower the present embodiment below:
Pipe need to be stretched or shrinks time, control handle 6 as long as slide, controlling handle 6 is with movable slider 4 in the interior slip in tunnel 50, in the time that slide block 4 slips make lining 5 offset with the block reinforcement 60 of controlling any side of handle 6, dead slot 41 is just in time positioned at needle roller 3 tops, and needle roller 3 can slide in dead slot 41, and inner tube 2 is with respect to outer tube 1 release, now can stretch or shrink inner tube 2, as shown in Fig. 2,3,8,9.
When completing the stretching of pipe or shrinking, unclamp and control handle 6, slide block 4 returns back to initial position under the restoring force effect of back-moving spring 7--and needle roller 3 is between groove 20 and the lower surface 40 of slide block 4, and inner tube 2 locks with respect to outer tube 1, as shown in Fig. 1,7.
