Abstract

The utility model discloses a rotator structure which is mainly characterized in that the inner side of a rotary disk is sheathed with a base; a plurality of rolling balls are clamped between the rotary disk and the base; a bracket of rolling balls is installed between the rotary disk and the base; and all rolling balls are clamped in all gaps arranged at the bottom end of the bracket of rolling balls at equal intervals, so that all rolling balls are matched with each gap of the bracket of rolling balls and distributed between the rotary disk and the base uniformly and each rolling ball has average stress; the rotary disk and the base are stably combined into a body and can rotate, thereby preventing the shedding off of the base from the inner side of the rotary disc as all rolling balls are centered on a certain side when in use, simultaneously reducing the number of the rolling balls, and being capable of not only reducing the cost but also greatly reducing the integral weight; and the rotator structure is very practical and convenient.

Description

The spinner structure

Technical field

The utility model is about a kind of spinner structure, refer in particular to a kind of can be firmly in conjunction with the spinner structure of rotating disc and base.

Background technology

Being subjected to global climate warms up, surging and the outdoor activity general mood rise of international oil price, increasing people has selected to have concurrently environmental protection, the instrument that the bicycle of body-building and communication function is ridden instead of walk or moved as short distance, fashion not only, save money to can save energy again and subtract carbon, the result has caused the business opportunity of environmental protection notion, each emporium is also released the various product of bicycle one after another, because along with customer's environmental protection subtracts carbon consciousness new line gradually, add and stopped two last week, make bicycle concerning the modern, no longer just shopping, the walking-replacing tool of calling on a friend and transporting, and bicycle has not oil consumption, noiselessness, advantage such as pollution-free and easy to use, be used as body-building by many people especially, tool movement, or even utilize the leisure of bicycle as rotary island, the good companion of tourism.

Above-mentioned bicycle is used to stunt and when handgrip rotated with respect to the car body 360 deg, must be provided with a spinner in the preceding pipe box of bicycle, please refer to shown in Figure 5ly, and this spinner includes a base 6, a rotating disc 7 and a set collar 8, wherein:

This base 6 includes a sheathed ring 61 and two legs 62 that combine with sheathed ring 61, outside face annular in sheathed ring 61 is concaved with an installing groove 611, and this sheathed ring 61 is oblique to be provided with a joint-cutting 612 that wore sheathed ring 61, make this sheathed ring 61 have two inclined-planes that fit, in addition sheathed ring 61 is concaved with one against ring 613 at the outside face that is positioned at below the installing groove 611, and each leg 62 takes shape in the root edge of sheathed ring 61 respectively;

This rotating disc 7 combines with base 6 rotationally, be provided with one in inside and be installed with space 71, other this rotating disc 7 is provided with an aperture in end face, and 71 little going up bore a hole 72 than being installed with the space, and be provided with the following perforation 73 of an aperture in the bottom surface greater than last perforation 72, make perforation 72, down bore a hole 73 be installed with space 71 and be connected, this rotating disc 7 in the internal face that is installed with space 71 be concaved with one can with the annular groove 74 of the installing groove 611 relative connections of sheathed ring 61, and between annular groove 74 and installing groove 611, be provided with a plurality of balls 75;

The mutually sheathed combination of inside face of this set collar 8 and the sheathed ring 61 of base.

Yet above-mentioned spinner has following defective when reality is used:

1. above-mentioned spinner can freely not roll between annular groove and installing groove because ball fixes, if under the situation of ball negligible amounts, will concentrate on a certain side because of all balls, cause rotating disc and base only to have this side to fix and be separated from each other, cause handgrip built on the sand, have influence on bicycle knight's safety even.

2. above-mentioned spinner must use a large amount of balls, rotating disc could be combined with base rotationally, causes the weight of spinner to increase, and also causes the rising of cost of manufacture.
