Abstract
The utility model relates to a structural improved pedal rod. The utility model is characterized in that the utility model is composed of a circular tube rod and a lining section provided with a screw hole; the lining is embedded in the circular tube rod, and the lining and the circular tube rod form an interference fit; the pedal rod processed and formed by the prior monobloc forging mode is designed into an assembly structure; after each component is respectively processed, the components are assembled into integration. The utility model has the advantages that the processing operation can be simplified, the processing is convenient, the used materials are less, the weight is light, and the manufacturing cost is low. The pedal rod of the structure is matched with a bicycle, which is good for the reduction of entire bicycle weight.
Description
Technical field
The utility model relates to bicycle assembly parts, especially a kind of foot-driven lever of structural development.
Technical background
Be the needs of the special purpose that satisfies bicycle, the common thread connecting mode installation foot of the front wheel spindle of bicycle or hind axle two ends treadle, the foot-driven lever that this symmetry is installed in the wheel shaft two ends can be convenient for people to pin and step on and stand on the bicycle.After existing foot-driven lever adopts the solid forging mode to shape usually, again through making after cutting, the tapping processing, promptly the end at the cylindrical body of rod bores the counterbore of system one aperture greater than the wheel shaft clamp nut, the tapped bore that can cooperate with the wheel shaft thread end in counterbore center bit system then.The foot-driven lever of this structure forges the expense cost height owing to adopt the solid forging mode to process, and it is heavy with the material volume, reduces by every means people under the situation of bicycle overall weight, and the foot-driven lever that adopts this structure obviously is unfavorable.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned foot-driven lever, provides that a kind of intensity is good, the foot-driven lever of the structural development of light weight.
The foot-driven lever of the utility model structural development is characterized in that: be made up of pipe bar and the liner section that is provided with screw, described lining is embedded in the pipe bar, is over-surplus fit structure between the two.
The foot-driven lever of the utility model structural development is with the foot-driven lever design and assembly structure of original global formation, and each assembly is assembled into one after processing respectively, both can simplify manufacturing procedure, convenient processing, and few with material, and deal is light, and manufacturing cost reduces greatly.The foot-driven lever of this structure cooperates with bicycle the decline that is beneficial to complete vehicle weight is installed, and result of use is good.
The concrete structure of the foot-driven lever of the utility model structural development is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the foot-driven lever structural representation of structural development.
The specific embodiment
Embodiment: the foot-driven lever that can be clear that structural development from Fig. 1 is made up of pipe bar 1 and the liner section 2 that is provided with screw, described liner section 2 is made of lining 21 and cylindrical nut 22, cylindrical nut 22 is embedded in an end of lining 21, and 21 of cylindrical nut 22 and linings are the interference fit connection structure; Concordant with pipe bar 1 end face to its breech face to insert pipe bar 1 headed by the screw end of liner section 2,1 on liner section 2 and pipe bar are connected for interference fit.The screw of set liner section 2 can be used as with the assembling of wheel shaft thread end and is connected in the pipe bar 1, and the socket end of liner section 2 then can be used as the sheath of wheel shaft clamp nut.
Claims (2)
