Description

A kind of whirligig of parasols

Technical field:

The utility model relates to the parachute kit technical field, refers in particular to a kind of whirligig that mainly applies to large-scale parasols.

Background technology:

Along with improving constantly of people's living standard, many families have all bought places such as backyard that large-scale parasols is placed on shelter, roof platform, because the function that parasols has sunshade, takes shelter from rain, people just can have a rest under umbrella in spare time, amusement.At present, the profile of parasols structure is traditional umbrella shape no longer as in the past, other parasols of all kinds occurred.See accompanying drawing 1,2, this is two parasols wherein, parasols shown in Figure 1, its umbrella cover 8 is a rectangle, parasols shown in Figure 2, its pillar 1 is positioned at a side of umbrella cover 81, and be not as parasols equally be positioned on the central axis of umbrella cover.We know the circular umbrella cover of general employing, and pillar is positioned at the parasols of umbrella cover central axis, when our swinging strut, can not produce the space of covering under the umbrella or position and change.Owing to the direction that shines upon can change in passing in time, so just caused when the user after staying for some time under the umbrella cover, shade that umbrella cover covers may just can't continue to cover the user, have to mobile parasols or from newly moving under the shade that umbrella cover covers of user.In addition, move the position if use to consider, and shade that umbrella cover covered or space can't change thereupon, these all bring some inconvenience to the user, and Fig. 1, the parasols of this shown in 2 type only needs swinging strut just can adjust the orientation of umbrella cover, reaches the purpose of oneself.But because parasols is very big, very heavy again, so general user is difficult to its rotation.Goal of the invention:

The purpose of this utility model just is to provide a kind of easily whirligig of Rotary sunshading umbrella.

Summary of the invention:

The utility model is achieved by the following technical solution: the lower end of pillar is a hollow-core construction, and pipe is fixed in the cavity of pillar, and central shaft is fixed on the base plate, and some bearing fixing are on central shaft, and pillar is socketed on the bearing by pipe.

Be fixed with three bearings on the central shaft, wherein two external diameter bearings identical with round tube inside diameter are separately fixed at central shaft two ends up and down, and a macro-axis bearing is on base plate and the bottom of fixed center axis, and the bottom of pillar places on the bearing cap of big bearing.

After adopting this device, between pillar and central shaft, adopted bearing arrangement, pillar is more prone to when the rotation of central shaft, and total has been firm.

The specific embodiment:

See accompanying drawing 3,4,5,8, the utility model comprises: pillar 1, central shaft 2, base plate 3 and bearing 41,42,43.The lower end of pillar 1 is a hollow-core construction, pipe 11 is fixed in the cavity 12 of pillar 1, central shaft 2 is fixed on the base plate 3, two external diameter bearings 41,42 identical with pipe 11 internal diameters are separately fixed at central shaft, and about in the of 2 two ends, end face bearing 43 places on the base plate 3, and the bottom of fixed center axis 2, and the bottom of pillar 1 places on the bearing cap 431 of end face bearing 43.Pillar 1 is socketed on the bearing 41,42 by pipe 11.

Pipe 11 can directly be processed by pillar 1, and promptly pipe 11 can affixedly be integral with pillar 1.

After adopting this device, owing to adopted bearing arrangement between pillar and central shaft, the sliding friction when making rotation is converted to rolling friction, pillar is more prone to when the rotation of central shaft, and total is firm.

For the user is more prone to when rotated, can on device, add a crank handle device, see accompanying

drawing

3,4,6,7,8, this is the utility model one specific embodiment, and wherein rocking handle box 5 places the top of central shaft 2 in the cavity 12, and is fixed on the pillar 1; turbine, worm mechanism are installed in the rocking handle box 5; wherein an end 611 of scroll bar 61 stretches out outside the rocking handle box 5, and offers a rectangle counterbore on it, and the position of corresponding scroll bar 61 rectangle counterbores offers a through hole 13 on the pillar 1.One end 641 of rocking handle 64, its cross section is corresponding with the shape size of scroll bar 61 rectangle counterbores, the affixed rectangle pin 631 in the lower end of the rotating shaft 63 of turbine 62, central shaft 2 is a hollow-core construction, in the cavity of central shaft 2, there is a rectangle pin 31 to be fixed on the base plate 3, a rectangle counterbore 71,72 is respectively offered at the two ends of connecting rod 7, and connecting rod 7 is socketed on the pin 631,31 by counterbore 71,72 two ends.

Connecting rod 7 can be directly and central shaft 2 be fixed together, and need not adopt rectangle pin 31 and the bottom on connecting rod 7 to offer rectangle counterbore 72.

Counterbore 71,72 on pin 631,31 and the connecting rod 7 is other shapes also, as triangle, and polygon or ellipses such as pentagon.

When using the utility model, this device is fixed on the base 9.Adjust the direction that parasols covers as need swinging strut 1, then the end 641 with rocking handle 64 passes through hole 13, inserts the rectangle counterbore on the scroll bar 61, rotation rocking handle 64, and driving scroll bar 61 will be around its axle center rotation.Rotating shaft 63 also will be rotated by the transmission of scroll bar 61, turbine 62, but because the affixed rectangle pin 631 in the lower end of rotating shaft 63 inserts in the rectangle counterbore 71 of connecting rod 7, and connecting rod 7 is socketed on the pin 31 of base plate 3, base plate 3 is fixed together with base 9 simultaneously, base 9 is fixed, so this moment connecting rod 7, rotating shaft 63 all maintains static, so around the rotation of its axle center the time, also will therefore drive pillar and begin to rotate when scroll bar 61 around turbine 62 rotations.

The utility model is mainly used in large-scale parasols, being convenient for people to the pillar of light Rotary sunshading umbrella, thereby regulates the space that umbrella cover covered.
