Abstract

The utility model relates to an umbrella frame of a bicycle, comprising a pedestal (1), a casing tube (2), a telescopic pipe (13), a positioning screw (4), and a positioning steering gear (5), wherein, the pedestal (1) is sheathed on the end head of the central axis of a bicycle handlebar through the mouth of a position sleeve on the pedestal (1), and the pedestal (1) is tightly fastened by the original matched screw cap of the end head; one end of the casing tube (2) is screwed in the joint (6) of the pedestal (1); therefore, the connection between an umbrella frame and a bicycle is quite firm. The positioned positioning screw (4) is provided with a small convex stem (8), which can be used to fasten screws by hands conveniently without using tools. The positioned positioning steering gear (5) can be turned along a vertical section, and can also be cooperated with the telescopic pipe (3) to be turned by 360 DEG along horizontal direction in the casing tube, ensuring the umbrella frame be used on the rainfall condition of any wind direction. The utility model has the advantages of firm connection and easy use.

Description

Supporting device for attaching umbrella to bicycle

The utility model relates to bicycle umbrella frame.

No. 90214821.4 utility application of China have proposed a kind of bicycle umbrella frame of being made up of pedestal, connecting rod, universal moving part and socket, because set connecting rod can't stretch, the socket size is fixing, and used umbrella umbrella bar is not of uniform size, length is different, so this umbrella stand is to the user of different situations and the umbrella of the different size of holding, its commonality is relatively poor.The bicycle umbrella frame of forming by short sleeve, stationary pipes, latching device, telescopic pipe, steering hardware, folder mouth that No. 91214487.4 utility application of China provide, owing to set locking device structure more complicated, the production and processing difficulty is bigger; The fixing screw that adopts in the set steering hardware is a plain screw, thereby instrument must be used usually in fastening location; Set short sleeve adopts two fans to be clipped on bicycle handle bar's axis, and its environment that connects steadiness relative proper motion car sharp pounding is very apparent poor; Its folder mouthful steel disc splice grafting that adopts two shapes to embrace pincers forms in addition, and the size shape of its mouthful is once determining that then the umbrella bar of different sizes then is difficult to clamp.So it is poor that the steadiness of this umbrella stand, commonality show, use also to make things convenient for inadequately.

The utility model purpose is to provide a kind of connection firm, bicycle umbrella frame easy to use.

The utility model purpose can realize by following scheme: umbrella stand base, sleeve pipe, telescopic pipe, location deflector are set, an interface and a locating bush opening that is shaped on screw thread is arranged on this base, this interface is used for connecting with the sleeve pipe threaded one end, this running-on is used to be enclosed within the termination of bicycle handle bar's axis, fastening with nut, be shaped on the little turning handle of two convexs at the fixing screw root.Be provided with one and connect the location deflector that constitutes with a umbrella bar cramp mouth by steering knuckle.Steering knuckle one end of this location deflector has the connection screw, is used for realizing Bolt Connection with the screw that connects of telescopic pipe one end, has a screw on umbrella bar cramp mouth, is used for fixing screw and screws in fastening umbrella bar.

Also have screw on the one distolateral wall of set sleeve pipe, telescopic pipe places in the sleeve pipe flexible, and can screw in fastening location in this screw by fixing screw.

Set umbrella bar cramp mouth surrounds with metal sheet, and its shape is by two planes and a curved surface and constitute.Have a screw on the wherein relative plane with curved surface.

Because the set base of the utility model is to be enclosed within on the bicycle handle bar axis termination by the locating bush opening on it, and the nut of using first wife on this termination just is fastening, thereby can be connected on the bicycle with being fixed, in the time of must be with this umbrella stand, just sleeve pipe is screwed on the interface of base, so connect very firm; Set fixing screw is provided with the little turning handle of convex, therefore must serviceable tool, and just available hand-tight solid screw; Set umbrella bar cramp mouth adopts a concave curvatures also to cooperate fixing screw to push up the bar of clamping, so that the umbrella bar of different sizes can both be stabilized is fastening, this umbrella stand is had connect firm, advantage easy to use.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

The utility model is made up of base (1), sleeve pipe (2), telescopic pipe (3), fixing screw (4), location deflector (5).Base (1) is provided with the interface (6) that inwall is shaped on screw thread, is provided with the tabular locating bush opening of spill (7).One end outer wall of sleeve pipe (2) is shaped on the screw thread that matches with interface (6) inner thread, is used for and base (1) thread connection, has screw (18) on the other end sidewall of sleeve pipe (2).Telescopic pipe (3) one ends are shaped on screw (12), and its other end can place in the sleeve pipe (2) flexible, and screw in fastening location in the screw (18) by fixing screw (4).Fixing screw (4) is made up of spiral shell head (19), top platform (20) and the little turning handle of convex (8).Location deflector (5) connects formation by steering knuckle (9) with umbrella bar cramp mouth (10), steering knuckle (9) is provided with screw (11), be used for realizing Bolt Connection with the screw (12) of telescopic pipe (3), and can turn in 270 ° in vertically, cooperate telescopic pipe (3) in sleeve pipe (2), in horizontal surface is done 360 °, to turn to, make this deflector (5) can in practical space, make any orientation and turn to, guaranteed that this umbrella stand uses under the rain condition of any wind direction.

The sidewall of set umbrella bar cramp mouth (10) is surrounded by two planes (13), (14) and a curved surface (15), has between plane (14) and the concave curvatures (15) on a breach (16), plane (14) to have screw (22).The umbrella bar screws in the fastening location of screw (22) by fixing screw (4) in breach (16) places concave curvatures (15).

Each parts of the utility model umbrella stand are all made with metallic material, also availablely mould firmly, the electric bakelite material preparation.
