At above-mentioned defective of the prior art, the purpose of this utility model provides a kind of fast-assembling child's bicycle jockey pulley frame that does not need serviceable tool can finish assembling fast.
The technical solution of the utility model is: a kind of fast-assembling child's bicycle jockey pulley frame, it comprises the jockey pulley support that is removably mounted on the bicycle rear support, the two ends of described jockey pulley support are respectively first free end and second free end, described first free end is provided with jockey pulley rotationally, it is characterized in that: also removably be provided with the outer cover that cross-sectional plane is the lengthwise of U-shaped on the described bicycle rear support, the described second free-ended cross-sectional plane be U-shaped and insert described outer cover and described bicycle rear support between, and removably be connected with described outer cover by clamping pin mechanism.
Preferably, described jockey pulley support and described outer cover are equipped with pin-and-hole, and described clamping pin mechanism is U-shaped jump ring, and the described U-shaped jump ring two free ends outside respectively is provided with the pin that can insert described pin-and-hole.
Preferably, a pin of described U-shaped jump ring passes a pin-and-hole of described jockey pulley support, and another pin of described U-shaped jump ring passes another pin-and-hole of described jockey pulley support and the pin-and-hole on the described outer cover.
Preferably, laterally be provided with hind axle between the described bicycle rear support.
Preferably, a free end of described jockey pulley support is semi-circular indentation, and described semi-circular indentation is resisted against on the described hind axle.
Preferably, be arranged with stressed cover on the described hind axle, described jockey pulley support semi-circular indentation is resisted against described stressed putting.
Preferably, described bicycle rear support is provided with back stay, and described outer cover is fixed on the described back stay by screw.
Preferably, described hind axle passes described outer cover, and described hind axle two ends are by the fixing described outer cover of nut.
The novel a kind of fast-assembling child's bicycle jockey pulley frame that provides of this use, its reasonable in design is installed quick and conveniently, need not to be aided with instrument and can finish assembling, and assembly quality is reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the lateral plan of loading onto the child's bicycle jockey pulley;
Fig. 2 is the cross sectional drawing of child's bicycle jockey pulley part;
Fig. 3 is the lateral plan of trailing wheel part;
Fig. 4 is the section-drawing of A-A part among Fig. 3;
Wherein: 1-jockey pulley, 2-jockey pulley support, 3-screw, the stressed cover of 4-, 5-outer cover, 6-chain guard, 7-back stay, 8-U type jump ring, 9-hind axle.
The specific embodiment
In order to make those skilled in the art person understand the utility model scheme better, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing the utility model is described in further detail.
Shown in Fig. 1-4, fast-assembling child's bicycle jockey pulley frame comprises that it comprises the jockey pulley support 2 that is removably mounted on the bicycle rear support, jockey pulley support 2 one free ends are provided with jockey pulley 1 rotationally, also removably be provided with the outer cover 5 that cross-sectional plane is the lengthwise of U-shaped on the above-mentioned bicycle rear support (not shown), above-mentioned jockey pulley support 2 another free ends insert between above-mentioned outer cover 5 and the above-mentioned bicycle rear support, and removably link together by a clamping pin mechanism and above-mentioned outer cover 5, it is U-shaped jump ring 8 that the utility model is selected the clamping pin mechanism of preferred forms.
As shown in Figure 3-4, all there is a pin at U-shaped jump ring 8 two ends, the pin length of one end is long than the pin of the other end, one free end of jockey pulley support 2 is semi-circular indentation, and two pin-and-holes are arranged on the jockey pulley support 2, and also there is a pin-and-hole position relative with one of them pin-and-hole on the jockey pulley support 2 on the above-mentioned outer cover 5, long any the pin of U-shaped jump ring 8 can pass the pin-and-hole relative with this pin-and-hole on pin-and-hole on the jockey pulley support 2 and the outer cover 5, be stuck in the pin-and-hole on the outer cover 5, be used for spacingly, outer cover is fixed; Short any the pin of U-shaped jump ring 8 only passes a pin-and-hole on the jockey pulley support 2, like this since, U-shaped jump ring 8 can not fall down in jockey pulley support 2 inside.
