Abstract

The utility model discloses a sunshade stand arranged on bicycles, which comprises two splints fixed on a horizontal handlebar and a sunshade handle clip fixed at an upper end of an upper rod. Wherein, a center of the sunshade clip is moveably fixed with a grip bolt and a grip nut. A lower end of the upper rod and an upper end of a lower rod are moveably fixed with a circular clip ring. In addition, a lower end of the lower rod and an upper end of a long splint are moveably fastened by a circular clip ring. The circular clip ring at the upper end of the lower rod forms an angle of 90 degrees with that at the lower end of the lower rod. A relative adapting face of circular clip ring respectively on the long splint, the upper rod and the lower rod is provided with radial hackle marks. The sunshade stand is not only capable of adjusting frontward and backward position of the sunshade but also the leftward and rightward position, thus achieving an optimal shading effect. Combination of the hackle marks and fixation of the grip bolt and nut prevent skid. While the stand is idle, the stand is folded and easily withdrawn and characterized by simple structure, reliable locating, light weight and great convenience.

Description

Bicycle umbrella frame

Affiliated technical field

The utility model relates to a kind of umbrella stand that is fixed on the parasols in the bicycle handle bar.

Background technology

In the summer of sweltering heat, people particularly woman generally use umbrella stand that parasols is installed on bicycle. and Chinese patent ZL01251684.8 discloses a kind of telescoping bicycle umbrella frame, comprise permanent seat, rod assemblies and umbrella bar cramp tightly install, rod assemblies comprises a U-shaped bar and a L shaped bar, weld a hollow tubular in the arc tips of U-shaped bar, the minor face of L shaped bar is set in the hollow tubular, and fix by nut, two circular holes that supply the U-shaped bar to pass are arranged on permanent seat, and the termination of U-shaped bar is a die.Its weak point is that position, the left and right sides can not be regulated, and umbrella can not be regulated with the irradiating angle of sunlight, reaches best shaded effects.

Summary of the invention

Can not regulate the deficiency of the position, the left and right sides of umbrella in order to overcome existing bicycle umbrella frame, the utility model provides a kind of bicycle umbrella frame, and this bicycle umbrella frame can not only be regulated the front and back position of umbrella, and can regulate the position, the left and right sides of umbrella, reaches best shaded effects.

The technical scheme that its technical matters that solves the utility model adopts is: comprise the two clamping plates that is fixed on the handlebar transverse tube, upper boom upper end fixing umbrella folder; have fastening bolt and nut movable fixing in the middle of the umbrella handle folder; upper boom lower end and lower beam upper end are movable fixing; the lower beam lower end is movable fixing with long clamping plate upper end; it is characterized in that: the circular clamping ring of lower beam upper end and the circular clamping ring of its lower end are 90 °; long clamping plate upper end and upper boom lower end are circular clamping ring, and the relative engagement face of the circular clamping ring on long clamping plate, upper boom and the lower beam all is shaped on radially groove.

The circular clamping ring of described upper boom lower end has together the therefrom outer wide radial slot of mind-set.

The beneficial effects of the utility model are, the circular clamping ring of the circular clamping ring of long clamping plate and lower beam lower end radially groove cooperates, and unclamps fastening bolt and nut scalable left and right directions; The circular clamping ring of lower beam upper end and the circular clamping ring of bar lower end radially groove cooperate, and unclamp fastening bolt and nut scalable fore-and-aft direction.Owing to be that groove cooperates and fastening bolt to be arranged again and nut is fixing can not slide, not the time spent not only collapsible but also can take away easily, simple in structure, the location is reliable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model structural representation.

Fig. 2 is the left view of Fig. 1.

.1. umbrella handle folder among the figure, 2. fly nut, 3. bolt, 4. upper boom, 5. fly nut, 6. bolt, 7. lower beam, 8. fly nut, 9. bolt is 10. lacked clamping plate, 11. long clamping plate, 12. nuts, 13. bolts.

The specific embodiment

At Fig. 1; Among Fig. 2; Umbrella handle folder (1) is welded in the upper end of upper boom (4); In order to clamping parasols umbrella handle; The centre has half-round head square neck bolt (3) and wing nut (2) to be fixed again; Upper boom (4) is round steel or stainless steel round steel; The lower end is welded with mating surface the radially circular clamping ring of groove; Lower beam (7) is round steel or stainless steel round steel; Two ends all are welded with mating surface up and down has the circular clamping ring of groove radially and both to be 90 °; Wherein the circular clamping ring of lower end therefrom is shaped with together than the slightly wide radial slot of half-round head square neck bolt (9) diameter under the mind-set; Being convenient to unclamp when needed wing nut (8) will take away more than the upper boom (7); The circular clamping ring circle center of lower beam (7) upper end is the square hole that cooperates with half-round head square neck bolt (6); Long clamping plate (11) upper end is welded with mating surface the radially circular clamping ring of groove; The circle center is the square hole that cooperates with half-round head square neck bolt (9); Cooperate with 4 pieces of bolts (13) and nut (12) with short clamping plate (10) and to be fixed on the handlebar transverse tube; The circular clamping ring of the circular clamping ring in upper boom (4) lower end and lower beam (7) upper end is movable fixing with half-round head square neck bolt (5) and wing nut (6); The circular clamping ring in lower beam (7) lower end is movable fixing with half-round head square neck bolt (9) and wing nut (8) with the circular clamping ring in long clamping plate (11) upper end, and wing nut is more convenient to be turned with hand. After long clamping plate, short clamping plate, upper boom and lower beam make, but chromium plating or other surface treatments are to increase aesthetics.

During use, at first the length clamping plate are fixed on bicycle handle bar's transverse tube, circular clamping ring on long clamping plate, upper boom and the lower beam is the groove relative engagement radially, fix with fastening bolt and fly nut respectively after regulating the position, open umbrella handle then and clamp umbrella handle and fix with fastening bolt and fly nut.General length clamping plate are fixed on no longer dismounting on bicycle handle bar's transverse tube, take off umbrella after, upper boom and following rod folding or fell to handlebar again; Perhaps connecting umbrella band umbrella stand extracts from the upper boom lower end and takes away.
