Abstract

The utility model relates to a self-rotating roundabout for children, being composed of a vertical shaft, a seat capable of rotating around the vertical shaft, and a manual driving device. A flywheel structure is used as a driving part; the seat can be rotated around the vertical shaft by pushing and pulling an operating rod. The self-rotating roundabout has the advantages of simple structure, convenient assembly and disassembly, low manufacturing cost, no requirement for an applied power, simple operation, labour saving, and flexible and reliable running. The self-rotating roundabout for children can be used for physical exercise and increasing interest for children, and is suitable for playing occasions for children in countryside, such as primary schools, kindergartens, etc.

Description

Children's rotation tourist bus of relying on oneself

The utility model belongs to roundabout, is specifically related to a kind of manual children rotation tourist bus of relying on oneself.

In some large-scale children playgrounds, generally all be provided with various types of recreational machines, wherein roundabout is subjected to children's welcome very much.This class recreational machine mostly is electronic greatly, complex structure, and volume is bigger, needs special messenger's operational administrative, and the fabrication and installation expense is higher, therefore only is adapted at the local preferably use of dynamic power supply and economic condition.For vast rural area, remote mountain area particularly underdeveloped, children there then unconditionally enjoy the enjoyment of rotation recreation.

The purpose of this utility model provides a kind of simple in structure, and is easy for installation, and not electricity consumption, oil consumption not are suitable for the employed manual children of juvenile's playground such as rural area, primary school, the kindergarten rotation tourist bus of relying on oneself.

Technical solution of the present utility model is:

Children's seat, manual driving device that the rotation tourist bus rotates by vertical shaft, around vertical shaft of relying on oneself formed.At the vertical shaft middle part rotary sleeve is housed, axle sleeve is evenly distributed in pivoted arm, and seat is equipped with in the pivoted arm outer end.Manual driving device is positioned at rotary sleeve below, and its drive part adopts flywheel structure, and the flywheel core retainer plate is fixedlyed connected with vertical shaft, in the outer round recessed of core retainer plate very heavy spring and very heavy is housed, and the interior very heavy tooth on very heavy and the Case of fly-wheel meshes; The Case of fly-wheel end face is provided with pole socket, is inserted with the hand-drive action bars in the pole socket, and the handle of action bars is positioned at seat one side.In the vertical shaft bottom triangular support bracket is housed, the vertical shaft top is provided with the sunshade decorative umbrella.

For seat is rotated flexibly, upper and lower two dish rolling bearings are housed, in rotary sleeve with the resistance of reducing friction.

During rotation, pushed away forward by operator's hand-held operation bar, the flywheel of drive unit is in and surmounts state, when being pushed into when forming certain angle with seat, to the pullback operation bar, very heavy and the interior very heavy tooth engagement that puts outward that this moment, flywheel core put, action bars blocks motionless, under the effect of pulling force, seat is taken advantage of a situation and is turned over respective angles forward, and then continue to push away, pull back action bars forward, so repeatedly, seat just can rotate around vertical shaft.

The utility model modern design, simple in structure, cost of manufacture is low, does not need additionaling power, and is easy and simple to handle laborsaving, goes slick, safe and reliable, and the dismounting conveniently moving is a kind of rotation tourist bus of relying on oneself that can take exercises, increase children's enjoyment, be easy to generally promote.

Further describe the utility model below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation;

Fig. 2 is Figure 1A one A view;

Fig. 3 is Figure 1B-B view.

Wherein: 1, seat 2, pivoted arm 3, rotary sleeve 4, vertical shaft 5, sunshade decorative umbrella 6, rolling bearing 7, manual driving device 8, action bars 9, handle 10, triangular support bracket 11, pole socket 12, Case of fly-wheel 13, interior very heavy tooth 14, groove 15, very heavy spring 16, very heavy 17, flywheel core retainer plate

As shown in Figure 1 and Figure 2, vertical shaft 4 is fixedly installed on the ground by triangular support bracket 10.Rotary sleeve 3 is equipped with at the vertical shaft middle part, and upper and lower two dish rolling bearings 6 are housed in the axle sleeve 3; Be welded with cross pivoted arm 2 at axle sleeve 3 circumference, pivoted arm 2 ends are fixed with seat 1.Manual driving device 7 is positioned at the rotary sleeve below, its drive part adopts flywheel structure, also can utilize the flywheel of existing bicycle, as shown in Figure 3, the flywheel core retainer plate 17 that is positioned at inner ring is fixedlyed connected with vertical shaft 4, fluted 14 on the flywheel core retainer plate cylindrical, be equipped with in the groove very heavy spring 15 and very heavy 16, very heavy 16 with Case of fly-wheel 12 on 13 engagements of interior very heavy tooth.Pole socket 11 is arranged on the Case of fly-wheel end, and action bars 8 is inserted in the pole socket, and its handle 9 is positioned at seat one side, and operation is very easy.

For making the rotation tourist bus of relying on oneself more both artistic and practical, be provided with sunshade decorative umbrella 5 at the vertical shaft top.

These children rotation tourist bus of relying on oneself can be taken four-player simultaneously, if will increase numbers of seats, with the corresponding amplification of pivoted arm diameter, seat is even number and is symmetrically distributed.As required, also can change seat shape, be made into styles such as aircraft, airship, train, and connect to form by pivoted arm.
