Description

The adjustable bicycle sun-shading device

The utility model relates to daily necessities, particularly sunshade tool.

China is a bikedom, and the whole nation has tens million of of bicycles, because bicycle is flexible, easily easily repair, cheap, the advantage of aspects such as dependable performance, welcome by broad masses, become the main vehicle of the on and off duty and short distance dealing of China both urban and rural residents.But bicycle also exists a lot of shortcomings, and can't hide body in wherein riding is main aspect, especially the sleet sky and summer the sky ride even worse.At present rain cape for bicyclist is a more satisfactory utensil in riding in the sleet sky, but summer with regard to the needs of incompatibility sunshade.In order to adapt to sunshade needs by bike in summer, the very simple bicycle umbrella device of a kind of structure was arranged on the market in recent years: it is to be 250mm with three length, the straight-bar of diameter 11mm, fixing umbrella lower end, upper end is fixed on the bicycle front fork hanging bolt, and two joints are fixing respectively with up and down for a middle joint.Its principle is: the bolt chuck tension method on the Magnetic gauge stand.Adopt the shortcoming of this method, the firstth: turn to dumbly, riding transfer backward, the sunshade angle can't be adjusted; The secondth, clamp firm inadequately.

The purpose of this utility model is: design and a kind ofly do not contact with human body, turn to flexibly, shaded effects are the bicycle sun-shading device preferably.

In order to achieve the above object, the connection structure of the utility model sun-shading device pipe link has been done improvement.Its groundwork is that the universal movement with spheroid combines with the locking effect of latch.

Its pipe link comprises two parts up and down, and the bottom of upper connecting rod is a spheroid, and there is a spring bar by ball centre the centre, and spring bar is made up of two poles of thickness, and employing is threaded, the lower surface chamfering of spring bar.There is the concave surface that matches with the upper connecting rod sphere upper surface of lower connecting rod, and a plurality of concave points are arranged on the concave surface, and the diameter of concave point and spring bar lower end diameter match; Last lower connecting rod adopts internal and external threads phase fit.Upper connecting rod can a plurality of direction rotational angles.Spring bar extension and contraction control structure is: the spring bar upper surface is the U-shaped groove, matches with the button pin that is installed on the pipe link, and button pin is a Cylinder, has radial slot on it.

Adopting the sun-shading device after the above-mentioned improvement structure, have and turn to flexibly, clamp firmly, by adorning characteristics such as easy to use, good looking appearance, is more satisfactory bicycle sunshade apparatus at present.

The utility model is described in further detail below in conjunction with the embodiment of accompanying drawing:

Pipe link as shown in the figure is made up of joint 1, upper connecting rod 4, lower connecting rod 9, button pin 2 is housed on the upper connecting rod 4, button pin is the garden cylindricality, have radial slot on it, match with the U-lag of spring bar 3 upper surfaces, be with pull back spring 5 on the spring bar 3, chamfered is carried out in the lower surface of bar, and the diameter of the concave point 11 on the concave surface 7 of lower connecting rod 9 upper surfaces is consistent with spring bar lower surface diameter.Upper connecting rod 4 adopts internal and external threads 8 lockings with lower connecting rod 9.Pipe link is fixed by mount pad 10 and bicycle.Press button pin 2, spring bar 3 (length of its spring bar can be adjusted by screw thread), because the effect self-return of pull back spring 5, swing upper connecting rod 4 is regulated required angle, loosen button 2, swing back and forth a little, automatically spring bar is inserted in the concave point 11 on the concave surface 7 under the action of the spring of spring bar 3 on button 2 and finish positioning function.

Claims (3)

1. sun-shading device, have umbrella body (umbrella bar), pipe link, it is characterized in that upper connecting rod (4) bottom is spheroid, there is a spring bar by ball centre (3) centre, the top of lower connecting rod (9) is the concave surface (7) that matches with the upper connecting rod spheroid, there are a plurality of concave points (11) centre, and last lower connecting rod adopts internal and external threads cover (6) to connect.

2. sun-shading device as claimed in claim 1, the lower surface that it is characterized in that spring bar (3) is the garden cylinder, concave point (11) diameter in lower connecting rod (9) the top concave surface (7) and the garden cylinder diameter of spring bar (3) lower end match.
