The specific embodiment
In order to describe structure of the present utility model, Characteristic in detail, the existing following preferred embodiment of act also cooperates description of drawings as follows.
As shown in Figure 1 to Figure 3, the bicycle chain wheels 1 of preferred embodiment that the utility model provides, the hinge wheel 30 that includes a pedestal 10, a plurality of connecting element 20, a maximum outside diameter, and one first sprocket wheel 40, one second sprocket wheel 50, one the 3rd sprocket wheel 60 and one the 4th sprocket wheel 70, each sprocket wheel according to its number of teeth number sequentially uniformly-spaced alignment arrangements at the outer peripheral face of pedestal 10.
Hinge wheel 30 is located at the first surface 13 of supporting arm 12, and the through hole 15 of corresponding the first rank section 141 is provided with a plurality of mounting holes 31.
Connecting element 20 quantity in the present embodiment is 12 and divides into two groups, and connecting element has a large-diameter portion 21, and a long column 22 and a short column 23 protrude out from large-diameter portion 21 both sides respectively.
The first sprocket wheel 40, the second sprocket wheel 50, the 3rd sprocket wheel 60 are provided with mounting hole 41,51,61,71 with the 4th sprocket wheel 70 equal corresponding connecting elements 20.Thus, the first sprocket wheel 40 utilizes mounting hole 41 to be riveted on the short column 23 of connecting element 20, the long column 22 that 50 on the second sprocket wheel utilizes connecting element 20 sequentially passes through hole 15 in mounting hole 51 and the first rank section 141 towards second surface 14, and the long column 22 that connects the connecting element 20 of the first sprocket wheel 40 has enough length, penetrate the mounting hole 31 of hinge wheel 30 so will pass simultaneously the through hole 15 of the first rank section 141, and then hinge wheel 30 riveted joints can be positioned first surface 13.
To use another group connecting element 20 as for the 3rd sprocket wheel 60 and 70 on the 4th sprocket wheel, the 3rd sprocket wheel 60 is the short columns 23 that are riveted on connecting element 20 by its mounting hole 61, the long column 22 of recycling connecting element 20 passes the mounting hole 71 of the 4th sprocket wheel 70 and the through hole 15 of second-order section 142 towards second surface 14, and then the 4th sprocket wheel 70 is fixed in second-order section 142.
Therefore, the utility model is directly to utilize the large-diameter portion of connecting element as spacer structure, the long column of recycling large-diameter portion both sides and short column are as the connection structure of sprocket wheel, therefore can finish with the connecting element of lesser amt the structure assembling of chain wheel set, can promote the convenience of assembling, and take into account simultaneously structural strength.
In addition, supporting arm can arrange group number stepped and the corresponding connecting element of its exponent number, and can utilize one group of connecting element to fix two sprocket wheels that are positioned at second surface and the hinge wheel that is positioned at first surface has advantages of simple in structurely, easily carries out lightweight.
Again as shown in Figure 4, another preferred embodiment of bicycle chain wheels is provided for the utility model, its structure is general identical with previous embodiment, its textural difference is that connecting element 20 is not is integrally formed single component, but change by a columned rivet 24, and one the packing ring 25 that is sheathed on rivet 24 consist of, namely form the large-diameter portion 21 of previous embodiment with packing ring 25, can reach the purpose of this utility model and effect equally.
What this emphasized be, previous embodiment is that supporting arm is set as two rank sections, those skilled in the art can be adjusted into hierarchic structures single or other quantity rank sections according to need, simultaneously the corresponding length of adjusting the connecting element long column with organize number and can reach the effect identical with the utility model, should be considered as simple change of the present utility model.
In sum, bicycle chain wheels of the present utility model with commonly use structure and become by contrast more convenient and practical, sound construction and easily assemble and reach the purpose of this utility model.
