Abstract
The utility model discloses a bicycle front fork roller positioning structure; a disc brake hole is formed on the fork foot of the front fork; the positioning structure comprises a roller piece; a fixing hole corresponding to the disc brake hole is formed on the roller piece; the roller piece is locked up on the fork foot by screws through passing through the corresponding disc brake hole and the fixing hole; a positioning hole is further formed at the upper end of the roller piece; and when the roller is assembled, the positioning part at the upper end of the roller can be inserted into the positioning hole for positioning. The roller positioning structure can fix the roller piece by utilizing the disc brake hole on the original fork foot of the front fork and the roller piece can help position the roller, so that the influence on the product structural intensity through drilling holes on the fork foot can be effectively avoided and the positioning can be accurate.
Description
Technical field
The utility model relates to front fork structure of bicycle, refers in particular to bicycle front fork roller location structure.
Background technology
Present bicycle front fork utilizes the roller brake function, and traditional front fork roller locking mode has two classes: a class welding manner, and it mainly is front fork, the roller that is applied to irony; Another kind of is drilling-tapping on the fork pin 10 of front fork 1, and the roller fixed plate 12 that locks assists to locate roller 2, as shown in Figure 3.For the latter, because processing boring can destroy fork pin intensity, there is potential safety hazard, especially for aluminium spare, influence more outstanding.
The utility model content
Technical problem to be solved in the utility model is: a kind of bicycle front fork roller location structure is provided, and it can effectively locate roller under the prerequisite that does not influence product structure intensity.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bicycle front fork roller location structure, the fork pin of front fork is provided with the disc brake hole, this location structure comprises an Ativan, this Ativan is provided with and the cooresponding fixed orifice in disc brake hole, by means of screw passes corresponding disc brake hole and fixed orifice Ativan is locked on the fork pin; Ativan upper end also is provided with a knock hole, and when the assembling roller, the location division of the upper end of roller is corresponding inserts in the described knock hole and locate.
The beneficial effects of the utility model are: by utilizing on the front fork fork pin fixedly Ativan of original disc brake hole, assist to locate roller, not only effectively avoided on the fork pin, holing the influence of product structure intensity by Ativan, and accurate positioning.
Description of drawings
Fig. 1 is the exploded drawings of the utility model bicycle front fork roller location structure.
Fig. 2 is the assembly drawing of the utility model bicycle front fork roller location structure.
Fig. 3 is the assembly drawing of existing bicycle front fork roller location structure.
Below in conjunction with accompanying drawing the utility model is described further:
The specific embodiment
As shown in Figure 1, the utility model provides a kind of bicycle front fork roller location structure, is used for roller 2 is positioned the fork pin 10 of front fork 1, and fork pin 10 is provided with disc brake hole 11.
This location structure comprises an Ativan 3, and this Ativan 3 is provided with and disc brake hole 11 cooresponding fixed orifices 31, by means of screw 4 passes corresponding disc brake hole 11 and fixed orifice 31 Ativan 3 is locked on the fork pin 10; Ativan 3 upper ends also are provided with a knock hole 32, and in assembling during roller 2, the location division of the upper end of roller 2 20 is corresponding inserts in the described knock hole 32 and locate, and the state after the assembling as shown in Figure 2.
Ativan 3 comprises fixed end 301, positioning end 302 and the bending connecting portion 303 that connects described fixed end 301, positioning end 302, and described fixed orifice 31 is located on the fixed end 301, and knock hole 32 is located on the positioning end 302.
Locate the location division 20 of roller 2 upper ends by designing on the disc brake hole site that an Ativan is fixed in front fork 1 fork pin 10, thereby avoid boring to influence structural strength.
