Description
Technical field
This utility model relates to a kind of gearshift.
Background technology
The position-limit mechanism that handle bar lock is scheduled on diverse location would generally be provided with on gearshift of the prior art; it includes shell fragment assembly and is arranged on the castellated plates on handlebar base; during manipulator's shank; castellated plates is driven to rotate together so that shell fragment assembly elastic deformation, during release handle bar; roller on shell fragment assembly is inserted in the teeth groove of castellated plates; owing to the profile of tooth in castellated plates is hard state structure, therefore after long-time use, shell fragment assembly defatigation is easily caused to lose efficacy.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, thus provides a kind of gearshift, good stability.
nullThis utility model be employed technical scheme comprise that such: gearshift，Including gearshift body、Bottom rotates and is arranged at the handlebar on described gearshift body、Slide mutually with described handlebar the mandrel component arranged along the direction of axis line of described handlebar，Some gear grooves being connected are offered on described gearshift body，The shift finger matched with described shift slot it is fixedly installed on described mandrel component，It is provided with position-limit mechanism between described gearshift body and described handlebar，Described position-limit mechanism includes the shell fragment assembly being fixedly installed on gearshift body、The castellated plates assembly being fixedly installed on described handlebar，Described shell fragment assembly includes that the strip flexure strip being connected is fixed, with described gearshift body, in one end、It is sheathed on the sheath outside described flexure strip、It is arranged at the pressure head of described flexure strip end、Rotate and be arranged at the roller on described pressure head，Described castellated plates assembly includes arc、The profile of tooth locked groove being opened on the curved end of described arc，The trench bottom of described profile of tooth locked groove is provided with cushion，Described sheath includes outer rigid housing、It is fixedly installed on the elastic layer of described outer rigid housing inwall，Described elastic layer is fixedly connected with described flexure strip.
Improve further: described arc is one-body molded with described handlebar.
Improve further: described roller surface has reticulate structure.
Improve further: described roller dismantles setting mutually with described pressure head.
By using preceding solution, the beneficial effects of the utility model are: by the sheathed sheath in the outside of flexure strip, and there is in sheath elastic layer, thus improve the intensity of flexure strip, the trench bottom of this external profile of tooth locked groove arranges cushion, thus improve the fatigue strength of flexure strip, extend the service life of shell fragment assembly.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram；
Fig. 2 is enlarged drawing at the A of Fig. 1.
Wherein: 1, gearshift body；2, handlebar；3, mandrel component；4, flexure strip；5, sheath；6, pressure head；7, roller；8, arc；9, profile of tooth locked groove；10, cushion.
Detailed description of the invention
This utility model is further illustrated below in conjunction with the drawings and specific embodiments.
nullSuch as Fig. 1、Shown in Fig. 2，The open a kind of gearshift of this utility model，Including gearshift body 1、Bottom rotates and is arranged at the handlebar 2 on described gearshift body 1、The mandrel component 3 arranged with the slip of described handlebar 2 phase along the direction of axis line of described handlebar 2，Some gear grooves being connected are offered on described gearshift body 1，It is fixedly installed, on described mandrel component 3, the shift finger matched with described shift slot，It is provided with position-limit mechanism between described gearshift body 1 and described handlebar 2，Described position-limit mechanism includes the shell fragment assembly being fixedly installed on gearshift body 1、It is fixedly installed on the castellated plates assembly on described handlebar 2，Described shell fragment assembly includes one end and the described fixing strip flexure strip 4 being connected of gearshift body 1、It is sheathed on the sheath 5 outside described flexure strip 4、It is arranged at the pressure head 6 of described flexure strip 4 end、Rotate and be arranged at the roller 7 on described pressure head 6，Described castellated plates assembly includes arc 8、It is opened in the profile of tooth locked groove 9 on the curved end of described arc 8，The trench bottom of described profile of tooth locked groove 9 is provided with cushion 10，Described sheath 5 includes outer rigid housing、It is fixedly installed on the elastic layer of described outer rigid housing inwall，Described elastic layer is fixedly connected with described flexure strip 4.
Operation principle: by the sheathed sheath in the outside of flexure strip 45, and there is in sheath 5 elastic layer, thus improve the intensity of flexure strip 4, the trench bottom of this external profile of tooth locked groove 9 arranges cushion 10, thus improve the fatigue strength of flexure strip 4, extend the service life of shell fragment assembly.
Processing for convenience, described arc 8 is one-body molded with described handlebar 2.
In order to raising stability, described roller 7 surface has reticulate structure.
Changing roller 7 for convenience, described roller 7 is arranged with the dismounting of described pressure head 6 phase.
Of the present utility model ultimate principle and principal character and advantage thereof have more than been shown and described; skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; above-described embodiment and explanation described in principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications; in the range of these changes and improvements both fall within claimed this utility model, this utility model claims scope and is defined by appending claims and equivalent thereof.
