Fig. 2 is an axial sectional view of the present utility model.
Fig. 3 is the axial sectional view of last tooth cover 5.
Embodiment:
See figures.1.and.2, the parasol base of present embodiment is by last pin sheet 1 and the combination of leftover bits and pieces sheet 2 crosses, and rotation positioning device is installed in base, and vertical rod 18 is placed in this rotation positioning device.
Rotation positioning device is made up of pin tube 3, last tooth cover 5, low sleeve 6, locating tooth axle 9 etc., wherein pin tube 3 is fixed on the base by bolt 13, the top of pin tube 3 is with tooth cover 5, the bottom is with low sleeve 6, be provided with locating tooth axle 9 in the pin tube 3, pin tube 3 bottoms are installed with bearing 12, and low sleeve 6 bottoms are shaped on the axle bed of ccontaining bearing 12.Locating tooth axle 9 necks are shaped on boss 9.1, and boss 9.1 tops are shaped on outer tooth ring 9.2 upwards.Be fixed with back-up ring 14 in the tube of pin tube 3, this back-up ring 14 is run through in locating tooth axle 9 bottoms, conflicts with back-up ring 14 and boss 9.1 respectively in spring 10 two ends that are placed in locating tooth axle 9.Locating tooth axle 9 bottoms radially are shaped on slotted hole, and screw 15 passes pin tube 3 and this slotted hole, and restriction locating tooth axle 9 radially rotates with pin tube 3, and locating tooth axle 9 pin tube 3 relatively moves up and down in the slotted hole limited range.
Camshaft 7 two ends that cam 8 is housed pass vertical rod 18 tube walls and are connected with U-shaped handle 4, and cam 8 is touched with the top of locating tooth axle 9, and said structure constitutes the hold-down devices of locating tooth axle 9.Low sleeve 6 tops are provided with fixed cover 16, and screw runs through the fixedly axial position of low sleeve 6 of fixed cover 16 and pin tube 3, and upper sliding sleeve 6 can't be moved up.Connect by connecting rod 17 between last tooth cover 5 and the low sleeve 6, fixing before assembling, make things convenient for both to install.Vertical rod 18 cross sections are square or oval substantially, and the profile of last ring gear 5 and low sleeve 6 is identical with the inner wall shape of vertical rod 18, and vertical rod 18 is placed in ring gear 5 and low sleeve 6, and vertical rod 18 radially can't relatively rotate with both.
Working principle: under the general state, to rising to peak, conflict by the minor axis face of locating tooth axle 9 end faces and cam 8 under the effect of spring 10 for locating tooth axle 9, and the outer tooth ring 9.2 of locating tooth axle 9 meshes with the internal gear 5.1 of last tooth cover 5.Because locating tooth axle 9 is radially fixing with pin tube 3, can't rotate by relative positioning tooth axle 9 so go up tooth cover 5, vertical rod 18 and umbrella cover are fixed.When rotating handle 4, the rotation that faces down of the major diameter of cam 8 drives locating tooth axle 9 and moves down, and makes the internal gear 5.1 of locating tooth axle 9 outer tooth rings 9.2 and last tooth cover 5 break away from engagement; At this moment, but 9 rotations of last tooth cover 5 relative positioning tooth axles, last tooth cover 5 and low sleeve 6 can rotate around pin tube 5, and vertical rod 18 gets final product 360 degree rotation adjusting umbrella covers.Unclamp handle 4, under the effect of spring 10, locating tooth axle 9 moves up, again with last tooth cover 5 engagements, vertical rod 18 location.
The utility model by press down handle just can be like a cork 360 degree rotating upright posts drive umbrella cover and turn to Moving, compared with prior art, changed traditional base rotation mode, can adjust easily sunshade The position, so that base is done simply, small volume is instant packed like this, moves light during use. The utlity model has simple in structure, profile succinctly attractive in appearance, cost is low, easy for operation etc. excellent The point.
