The specific embodiment
Embodiment one
The removable parasol base structure of embodiment one is in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5.
Support is welded on the carriage center piece 7 by four poles 2 and consists of, and pole 2 distributes radially, and its shape as shown in Figure 3.
Referring to Fig. 1 or Fig. 2, support is fixed in the base housing 1, the below of support is provided with four levers 11, each lever 11 is positioned at below the corresponding pole 2, lever 11 also distributes radially, be fixed with balance pivot foot rest 8 on the pole 2, every group of lever 11 is connected with pole by fulcrum 10 connections on the corresponding fulcrum foot rest 8.
A universal wheel 9 all is equipped with in the outer end of each lever 11, and lead screw device is housed on the carriage center piece 7 straight down.
Perhaps support adopts a flat board, and position welding or riveted joint corresponding with lever on the flat board have the fulcrum foot rest, and dull and stereotyped center welding or riveted joint have central block, and lead screw device is housed on the central block.Above-mentioned parts or with described plate shaped support integral casting forming.
Described lead screw device structure is to be that carriage center piece 7 has axis hole at the center of support referring to Fig. 4, and the upper end of screw mandrel 13 is located in the above-mentioned axis hole and by back-up ring 17 axial limitings, screw mandrel 13 consists of the input block of lead screw device.
According to the principle of lead screw device, lead screw device mainly is comprised of screw mandrel and nut.The application of lead screw device has dual mode, and the one, screw mandrel rotates the drive nut and moves; Another kind is that nut rotation drive screw mandrel moves axially.
Rotate with screw mandrel 13 in the present embodiment structure and drive contiguous block 12 oscilaltions that are equivalent in fact nut, namely screw mandrel 13 as input block, contiguous block 12 as output block.
Hole wall is shaped with the screw thread that cooperates with screw mandrel 13 at the center of contiguous block 12, and contiguous block 12 is engaged on the screw mandrel 13 nut as lead screw device, the i.e. output block of lead screw device.
Be shaped with the connecting pin that equates with lever quantity around the contiguous block 12, the inner of each lever all is plugged on the contiguous block 12 by the connecting pin activity of correspondence.
Concrete connected structure is: lever 11 adopts square tube, and it is foxy that the connecting pin on the contiguous block 12 is shaped with horizontal cylinder, and the foxy activity of cylinder patches in the lever 11 that square tube is made.
Another kind of plug structure: horizontal cylinder fixedly is housed foxy on the inner termination of lever 11, connecting pin is made the square tube shape, and the foxy activity of cylinder patches in the connecting pin of above-mentioned square tube type.
Another plug structure: lever 11 adopts pipe, and the connecting pin on the contiguous block 12 is shaped with bulb, and the bulb activity patches in the lever 11 that pipe is made.
Also have a kind of plug structure: be fixed with bulb on the inner of lever, connecting pin is made round tube shape, and the bulb activity patches in the connecting pin of above-mentioned circular tube shaped.
Above plug structure all can make lever 11 and contiguous block 12 mutually flexible rotating and relative turnover slip in motion process, to guarantee lever 11 when the Angulation changes and the variation of distance aspect angle two of 12 of contiguous blocks, this variation can be known in comparison diagram 1 and Fig. 2 and find out.
Fig. 5 is the structure chart that removes behind the base housing, and is clear in order to illustrate, and the parts such as the pole of front, lever, universal wheel omitted do not draw.
In conjunction with Fig. 1 and Fig. 5 as seen, for the transverse shifting that prevents lever 11 causes lateral pressure to screw mandrel 13, the shape of balance pivot foot rest 8 is two pin sheets that curve flute profile, the pin sheet has enough width, lever 11 is engaged in the groove of two pin sheets formations, make balance pivot foot rest 8 reliably clamp lever 11 it is formed lateral Displacement, lever 11 is connected as fulcrum 10 with pin or bolt with balance pivot foot rest 8.
Be fixed with driven sprocket 14 at screw mandrel 13, be provided with the axle 3 of shaking the hand at support, be fixed with drive sprocket 16 on the axle 3 of shaking the hand, drive sprocket 16 is connected with driven sprocket and is connected by chain 15.
Rotation shakes the hand 5, and screw mandrel 13 rotates, because contiguous block 12 is actually the nut on the screw mandrel 13, and contiguous block 12 can not freely rotate by pining down of each lever 11, so when screw mandrel 13 rotated, contiguous block 12 produced and rises or the movement of decline.When contiguous block 12 rises, rise together in the inner of each lever 11, and 9 of each universal wheels of outer end descend together and stretch out; Otherwise when contiguous block 12 descended, the inner of each lever 11 descended together, and 9 of each universal wheels of outer end rise together, in the inner chamber of indentation base housing 1.
Embodiment two
The structure of embodiment two as shown in Figure 6, and is clear in order to illustrate equally, the parts such as the pole of front, lever, universal wheel omitted do not draw.
In the present embodiment, umbrella handle is installed the position that screw 6 moves to skew base housing 1 center, is used for umbrella handle is installed, and on screw mandrel 13, installs and shakes the hand 5.Rotation shakes the hand 5, and screw mandrel 13 rotates, contiguous block 12 liftings, and universal wheel descends and stretches out or the retraction of rising.
Umbrella handle is installed screw 6 skews and is arranged, and is 5 slot millings of shaking the hand, and can save link chain mechanism like this, is conducive to simplified structure.
Other part-structures are with identical described in the embodiment one.
Embodiment three
The structure of embodiment three is referring to Fig. 7, Fig. 8, Fig. 9, and the lead screw device that the present embodiment adopts is that the central block 7 at support has axis hole, is equipped with a nut 19 in the axis hole and with jump ring 20 axial limitings, screw mandrel 13 is engaged in the nut 19.
Drive the screw mandrel oscilaltion with nut rotation in the present embodiment structure, namely nut as input block, screw mandrel as output block.
Other structures are identical with embodiment one.
Equally, because contiguous block 12 can not freely be rotated by pining down of each lever 11, so screw mandrel 13 can not freely rotate, when nut 19 rotated, screw mandrel 13 will produce the movement of rising or descending like this.
Screw mandrel drives contiguous block 12 and moves, and when contiguous block 12 rises, rise together in the inner of each lever 11, and 9 of each universal wheels of outer end descend together and stretch out; Otherwise when contiguous block 12 descended, the inner of each lever 11 descended together, and 9 of each universal wheels of outer end rise in the inner chamber of indentation base housing 1 together.
The mounting flange center drilling of umbrella handle when screw mandrel 13 rises, puts in the umbrella handle.
