Abstract
The utility model discloses a bicycle crank. The bicycle crank comprises a handle body, a first connector and a second connector, wherein the first connector and the second connector are respectively arranged at two ends of the handle body, the first connector is fixedly connected with a mandrel of a bicycle, the second connector is fixedly connected with a pedal shaft, two sides of the handle body are both provided with grooves, a filling block and a sealing cover are sequentially arranged in each groove, and each filling block is provided with a plurality of through holes. Under the premise of ensuring the strength of the crank, the bicycle crank reduces the self weight and reduces processing cost.
Description
Technical field
The utility model relates to a kind of vehicle, is specifically related to a kind of bicycle crank.
Background technology
The handle body of existing bicycle crank is divided into solid construction, and weight is heavier like this, makes the bicyclist tired sense easily occur; And adopt smooth being connected between existing crank and the axle, skidding easily appears in this connection mode, and the phenomenon that crank drops can occur when serious.
The utility model content

The technical problems to be solved in the utility model provides a kind of lightweight, structural strength good, power transmission is good bicycle crank.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of bicycle crank, the first connector and the second connector that it comprises the handle body and is separately positioned on handle body two ends, the first connector is captiveed joint with the axle of bicycle, the second connector is captiveed joint with pedal shaft, the both sides of handle body all offer groove, and filling block and capping are installed in the groove successively.
Wherein, all offer a plurality of through holes on this each filling block.
Wherein, evenly be provided with a plurality of grooves on the endoporus circumference of this first connector, also be coaxially arranged with step on the endoporus of this first connector.
(3) beneficial effect
Compared with prior art, the utility model has alleviated the weight of crank self under the prerequisite that guarantees crank intensity, reduced tooling cost, and passes through the spacer shell transferring power between this crank and the axle, has improved the stability that connects.
Description of drawings
Fig. 1 is the structural representation of the utility model bicycle crank.
Fig. 2 is the exploded perspective view that the utility model bicycle crank is connected with axle.
Fig. 3 is the generalized section that the utility model bicycle crank is connected with axle.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but can not be used for limiting scope of the present utility model.
The structure of the utility model bicycle crank as shown in Figure 1, this bicycle crank 1 is Casting Parts, the first connector 11 and the second connector 13 that it comprises handle body 12 and is separately positioned on handle body 12 two ends, the first connector 11 is captiveed joint with the axle 3 of bicycle, the second connector 13 is captiveed joint with pedal shaft, the both sides of handle body 12 all offer groove 121, and filling block 14 and capping 15 are installed in the groove 121 successively, all offer a plurality of through holes 141 on each filling block 14.The utility model has alleviated the weight of crank self under the prerequisite that guarantees crank intensity, reduced tooling cost
Evenly be provided with a plurality of grooves 112 on the endoporus circumference of the first connector 11, also be coaxially arranged with step 111 on the endoporus of this first connector 11.The structure that this crank is connected with axle as shown in Figures 2 and 3, crank 1 is fixedly connected on the axle 3 by spacer shell 2 and bolt 4, the two ends of axle 3 are provided with cone 31 and the coaxial internal thread hole 32 that is arranged on this cone 31, this internal thread hole 32 matches with bolt 4, be provided with the conical bore 23 that matches with cone 31 on this spacer shell 2, be provided with a plurality of projections 22 that match with groove 112 on the outer fringe surface of this spacer shell 2, also offer regulating tank 21 on this spacer shell 2.
During installation, spacer shell 2 is goed deep in the endoporus on the first connector 11, groove 112 and projection 22 are fitted, cone 31 with axle 3 gos deep in the conical bore 23 of this spacer shell 2 again, penetrate and threaded portion screwed in the internal thread hole 32 of axle in from the opposite side of the first connector 11 bolt 4 at last, the head end of bolt 4 by constantly screwing bolt 4, fits tightly in conical bore 23 cone 31 against step 111.The connection of this structure can improve the stability that is connected between crank and the axle.
It below only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
