The specific embodiment

The present invention is described in detail below in conjunction with drawings and Examples.

The part identical with prior art used identical symbol in the accompanying drawing.

A kind of telescopic rack wheel of vertical type dust collector, comprise the drain pan 7 that constitutes body 1 and accommodate parts (not shown) such as dust sucting motor, fan, the drain pan 7 anterior control of dust tubes 16 that contain foreign substances such as dust of collecting, the suction nozzle 5 that body 1 bottom is formed by suction nozzle loam cake 3, suction nozzle bottom 4, the Moving caster 6 at suction nozzle 5 rear portions, it is inner and form the hose 12 etc. of air path system to be communicated with suction nozzle 5 and drain pan 7; What its drain pan 7 back sides were provided with that top is that hinge connects, the bottom is provided with rack wheel 29 regulates flexible bracing frame by positioner.

The two ends that the clip support 18 collar extension inner hinges that drain pan 7 back side levels set firmly connect are arranged with the T-socket frame 19 of abduction locating part 30 and Embedded Division 36, the vertical tube of T-socket frame 19 is socketed in through positioner on the locating slot 23 of inverted T-shaped support 20 vertical rods, and the support shaft 28 at inverted T-shaped support 20 cross bar two ends is provided with the spacing rack wheel 29 of rounded tabs 25.

The locating slot 23 of inverted T-shaped support 20 vertical rods is provided with several at a certain distance side by side, selects to adjust the height of bracing frame when confession combines with positioning edge 24.

The pole and the vacuum cleaner bottom 7 at clip support 18 rear portions fix as one, and its anterior collar extension is connected with the horizon bar hinge of T-socket frame 19.The positioner of T-socket frame 19 vertical tubes is the support inner panel 33 that is provided with at vertical mouth of pipe center line respective side pipe tap 31, support spring 35, fixing outside plate 34; And expose button top board 32 in the pipe of button 21, and inside pipe wall is provided with prominent in pipe and the vertically disposed positioning edge 24 of center line, and positioning edge 24 can be located by connecting with locating slot 23 slips of inverted T-shaped support 20 vertical rods.Support inner panel 33, fixedly outside plate 34 and button top board 32 are to have the sheet material that corresponding arc with tube wall is bent.

In button 21 that pipe tap 22 exposes and pipe button top board 32 vertical fixed be one, during pressing keys 21, the vertical rod of extruding inverted T-shaped support 20, make it overcome the support of tube wall offside resiliency supported inner panel 33, break away from positioning edge 24, can it is flexible, the height of selecting when adapting to the dust suction operation.When stopping pressing keys 21, under the support of resiliency supported inner panel 33, when the positioning edge 24 of T-socket frame 19 convexes snaps in the locating slot 23 of inverted T-shaped support 20 vertical rods, promptly realize the location.

T-socket frame 19 two ends in the bracing frame are symmetrical arranged the abduction locating part 30 of ovalize, and its major diameter is parallel with vertical tube; The preceding gap of Embedded Division 36 diameters≤clip support 18, when bracing frame being installed at drain pan 7 back sides, the Embedded Division 36 at T-socket frame 19 horizon bar two ends is embedded the preceding gap of clip support 18, the mobile and horizontal bar enters in the collar extension of clip support 18, and then the Embedded Division of the other end embedded the preceding gap of another clip support, promptly finish the installation of bracing frame.

The major diameter of abduction locating part 30 is greater than the distance of the clip collar extension center of circle to drain pan, and abduction locating part 30 is during with the horizon bar rotation of T-socket frame 19, can not continue rotation because of the major diameter of abduction locating part 30 pushes up to drain pan 7, or bracing frame continues abduction.

Being installed in support shaft 28 upper brackets takes turns the catch 25 in 29 outsides and forms gap 26 from the catch hole along radial direction, catch draw-in groove 37 external diameters at width 〉=support shaft 28 two ends of gap 26.Catch 25 self catcher film perforation centers are radial several fan-shaped projections that is divided into, with its plug-in card to catch draw-in groove 37 and difficult drop-off.

When She Ji the present invention uses like this, open the also bracing frame of abduction telescopic rack wheel 29, push the button 21 on the T-socket frame 19, the vertical rod of extruding inverted T-shaped support 20, make it overcome the support of tube wall offside resiliency supported inner panel 33, the positioning edge 24 that locating slot 23 on it breaks away from the T-socket frame 19, can pull out inverted T-shaped support 20 to suitable height, decontrol button 21, locating slot 23 on the resiliency supported inner panel 33 top inverted T-shaped supports 20 is located with the positioning edge 24 in the T-socket frame 19 and is cooperated, after promptly having realized utilizing vertical type dust collector to launch telescopic rack wheel, support the vertical type dust collector of slant operation.
