Abstract
The utility model relates to a split type flower -drum, include central siphon and the flower disc that is used for connecting the spoke, its characterized in that: the both ends of central siphon have screw thread portion, the middle part of central siphon, be located well axial region has between two screw portions, the diameter of well axial region is greater than the diameter of screw thread portion, join in marriage the dress respectively through the screw thread in the screw thread portion at central siphon both ends the flower disc, the flower disc includes disk body and sleeve pipe, the sleeve pipe is joined in marriage the dress through the screw thread and is in in the screw thread portion, radial screw hole has on the sleeve pipe, radial threaded hole joins in marriage and is equipped with locking screw. The flower disc of adorning different models can be joined in marriage to central siphon in this flower -drum to make the flower -drum assembly carry out the wheel that minimum adjustment made the applicable different models of flower -drum assembly through spending the hub assembly, with this use cost who reduces the flower -drum assembly through changing the wheel that the flower disc comes the different models of adaptation.
Description
Technical field
The utility model belongs to bicycle accessories technical field, particularly relates to a kind of split type flower-drum.
Background technology
Bicycle drive shaft is for installing the parts of spoke on bicycle hub.Flower-drum main body comprises central siphon and the floral disc for being connected spoke.The parts such as flower-drum and bearing, axle, ratchet base form flower-drum assembly, and flower-drum assembly is for connecting wheel and front fork.In conventional art, flower-drum is that integral type is shaped, a kind of flower-drum of model is merely able to the spoke of equipped a kind of model, because of flower-drum assembly structure complexity and usually used as a unitary device, so a kind of flower-drum assembly can only be equipped with a kind of spoke of model, thus making the range of use of the large portion parts (axle, ratchet base and bearing etc.) in flower-drum assembly be subject to the restriction of flower-drum, the use cost of flower-drum assembly is high.
Summary of the invention
The utility model provides a kind of split type for solving in known technology the technical matters that exists, and floral disc can dismounting and change, thus reduces the split type flower-drum of the use cost of flower-drum assembly.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: a kind of split type flower-drum, comprise central siphon and the floral disc for being connected spoke, it is characterized in that: the two ends of central siphon have threaded portion, the middle part of described central siphon, between described two threaded portions, there is middle shaft part, the diameter of described middle shaft part is greater than the diameter of described threaded portion, by screw thread equipped described floral disc respectively on the threaded portion at described central siphon two ends, described floral disc comprises disk body and sleeve pipe, described sleeve pipe is fitted on described threaded portion by screw thread, described sleeve pipe has radial screw bore, lock screw is fitted with in described radial screw bore.
The utility model can also adopt following technical measures:
The outer end of described radial screw bore has counterbore.
The advantage that the utility model has and good effect are:
A kind of novel split type flower-drum of this new design, central siphon in flower-drum can be equipped with the floral disc of different model, thus make flower-drum assembly can by changing the wheel of floral disc adaptive different model, carrying out minimum adjustment by hub assembly makes flower-drum assembly be suitable for the wheel of different model, reduces the use cost of flower-drum assembly with this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, central siphon; 1-1, threaded portion; 1-2, middle shaft part; 2, floral disc; 2-1, disk body; 2-2, sleeve pipe; 3, lock screw.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Referring to Fig. 1, a kind of split type flower-drum, comprising central siphon 1 and the floral disc 2 for being connected spoke.
The two ends of central siphon 1 have threaded portion 1-1.The two ends excircle of i.e. central siphon 1 has one section of outside thread respectively to form above-mentioned threaded portion 1-1.The middle part of described central siphon 1, between described two threaded portion 1-1, there is middle shaft part 1-2.The diameter of described middle shaft part 1-2 is greater than the diameter of described threaded portion 1-1, and the two ends of middle shaft part 1-2 form the shoulder protruding threaded portion 1-1 in the rear end of threaded portion 1-1.By screw thread equipped described floral disc 2 respectively on the threaded portion 1-1 at described central siphon 1 two ends.Namely described floral disc 2 comprises disk body 2-1 and sleeve pipe 2-2, and described sleeve pipe 2-2 is fitted on described threaded portion 1-1 by screw thread, described sleeve pipe 2-2 has radial screw bore, is fitted with lock screw 3 in described radial screw bore.The shoulder that floral disc 2 is formed by middle shaft part 1-2 carries out spacing to the floral disc 2 be fitted on the 1-1 of threaded portion, and lock screw 3 pairs of floral discs 2 carry out locked.In order to make the head of lock screw 3 embed in sleeve pipe, the outer end of radial screw bore has counterbore.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the premise without departing from the principles of the invention; some improvements and modifications can also be made; as: above-mentioned shoulder is made up of flange, and these improvements and modifications also should be considered as protection scope of the present invention.
