Abstract
The utility model discloses a kind of foot rest containing built-in spring, its structure comprises leg, leg rolling disc, the fixed fastener of being with built-in spring structure, this foot rest spring is built-in, whole foot rest rotational structure is closed in leg rolling disc and is fixed in by fixed fastener the place that foot rest is installed in bicycle, storage battery car etc. again, with the foot rest of traditional external spring sheet is higher than durability, the life-span is longer, need not worry that the spring situation such as to knock occurs pin.
Description
Technical field
The present invention relates to parts machining field, particularly relate to a kind of foot rest containing built-in spring.
Background technology
Bicycle, also known as bicycle or bicycle, the normally two small-sized land-going machines of taking turns.After people rides car, being power with foot pedal, is the vehicle of environmental protection.Bicycle accessories is the general designation to all parts of bicycle body and annex.The structural framing large according to vehicle body can be divided into: several large classes such as vehicle frame, tire, pedal parts, front fork assembly, chain, flywheel, people use bicycle to make walking-replacing tool or body building instrument is existing for a long time, but in use, traditional foot rest because of external spring so often knocked by pin and cause foot rest normally not pack up.
Summary of the invention
In order to stop the problem that traditional foot rest spring easily drops, the present invention has made Curve guide impeller, the present invention includes: fixed fastener, the leg with built-in spring structure, leg rolling disc; Described fixed fastener is fixed on the leg rolling disc back side; Described leg rolling disc comprises the bottom surface of isosceles right triangle and the sidewall with base vertical, and this sidewall thickness is 1cm; The leg activity of the built-in spring structure of described band is riveted on the right-angled apices place of described leg rolling disc;
Preferably, the leg of the built-in spring structure of described band comprises the pole of band turning; Have horizontal foot-driven lever in the middle part of described pole, turning one end far away and upper end also have horizontal dwang, and described spring structure is fixed on this dwang, and this dwang is used for the described leg rolling disc of movable riveted joint;
Preferably, described spring structure comprises urceolus, spring, plush copper; Described urceolus is hollow cylinder, and an one end face is fixed on the dwang of the leg of the built-in spring structure of described band, and another end face has hole; Described spring one end is fixed on the inner end surface of the non-perforate of described urceolus, and the other end and described plush copper are fixed, and described plush copper is stretched out by the perforate of described urceolus institute;
Preferably, the head of described plush copper is round and smooth, and described spring and plush copper total length in the raw equals the right angle length of side of described leg rolling disc; Described urceolus length is greater than described spring natural length and is less than the vertical length of described leg rolling disc right-angled apices to opposite side.
Preferably, two end points parts on described leg rolling disc hypotenuse have the outwardly convex meshing with the plush copper nose shape of the spring structure of the leg of the built-in spring structure of described band;
Preferably, described leg rolling disc hypotenuse there is slide rail, and be coated with organic oil;
Preferably, described leg rolling disc also comprises a top cover, and there is tapped bore at described leg rolling disc sidewall upper three summits place, and described top cover also has three holes corresponding with it, can be fixed on described leg rolling disc by top cover by screw.
Leg with built-in spring structure in the present invention can be stuck in two projections on leg rolling disc hypotenuse because of the plush copper on built-in spring, so this foot rest can realize put down pack up two states under locate, again because spring is built-in and it is inner to be enclosed in leg rolling disc, therefore spring can not occur drop and cannot pack up the situation of foot rest, and the airtight integral structure of whole foot rest, its durability is also high than the one-sided foot rest of tradition, and the present invention has advance compared to existing accessory in sum.
