Description
Technical field
The utility model relates to industrial transportation vehicle field, particularly a kind of tiller structure.
Background technology
In prior art, in industrial vehicle safety rate, as follows to the requirement of electric pallet truck: when tiller place is high-order or low level time, the tractive force of operation should be cut off.At present, the starting angular of electric walking tray truck tiller root is all controlled by micro-switch contact, control angle can only be adjusted by mechanical erection position, poor stability, and contact due to frequent bruising, micro-switch easily produces quality impairment, causes car to travel, and uses cause great harmful effect to user.
Utility model content
Main purpose of the present utility model is to overcome above-mentioned defect of the prior art, proposes a kind of employing resistance-type potentiometer, can set different speed, improve stability and the tiller structure in service life in the angle position that rotatable handle is different.
The utility model adopts following technical scheme:
A kind of tiller structure, is connected with car body, comprises handle and rotating shaft, it is characterized in that: also comprise support and potentiometer; This frame bottom is fixed on car body; These rotating shaft two ends are fixedly connected with handle through after cradle top; This potentiometer is provided with housing and actuating spindle, this housing to be fixed on support and to be provided with arc resistance track in it, this actuating spindle fixed cover to be located in rotating shaft and to be provided with the sheetmetal group contacted with arc resistance track, this sheetmetal group under rotating shaft drives arcuately resistance track slide to change output voltage.
Preferably, described cradle top is provided with two lugs, and this lug top is equipped with the through hole passed for described rotating shaft.
Preferably, wherein a lug is also provided with the fixed orifice of some fixing described housings, this fixed hole position is below described through hole, and described potentiometer is between this two lug.
Preferably, described actuating spindle offers groove, described rotating shaft is fixed with a card-bit part, be stuck in groove by card-bit part and achieve a fixed connection.
Preferably, described potentiometer adopts resistance-type potentiometer.
From above-mentioned to description of the present utility model, compared with prior art, the utility model has following beneficial effect:
The utility model is sheathed potentiometer in rotating shaft, this potentiometer is connected with controller, potentiometric actuating spindle is driven to rotate by rotating shaft, its sheetmetal group is slided in arc resistance track, thus exports varying voltage signal, feed back on controller, controller provides corresponding moving velocity instruction according to the value of setting, when realizing rotatable handle to different angles, have friction speed, improve stability and service life.

Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
Referring to figs. 1 through Fig. 5, a kind of tiller structure, comprises handle 10, rotating shaft 20, support 30 and potentiometer 40.This support 30 top is provided with two lugs 31, and be fixed on car body bottom this lug 31, top is equipped with through hole 32, and wherein a lug 31 is also provided with two fixed orifices 33, and this fixed orifice 33 is positioned at below through hole 32.These rotating shaft 20 two ends are fixedly connected with handle 10 sidewall after being each passed through the through hole 32 on two lugs 31.Potentiometer 40 is between this two lug 31 and be provided with housing 41 and actuating spindle 42.This housing 41 is fixed on the fixed orifice 33 of lug 31 by bolt lock, is provided with arc resistance track (not shown) in housing 41.This actuating spindle 42 to be sheathed in rotating shaft 20 and to be provided with the sheetmetal group (not shown) contacted with arc resistance track.Actuating spindle 42 offers groove 43, rotating shaft 20 is fixed with a card-bit part 21, be stuck in groove 43 by card-bit part 21 and achieve a fixed connection.This card-bit part 21 and rotating shaft 20 are for being threaded.This sheetmetal group can rotating shaft 20 drive under arcuately resistance track slide to change output voltage.
Potentiometer 40 of the present utility model adopts resistance-type potentiometer.This potentiometer 40 is connected with the controller of car body.When handle 10 rotates, rotating shaft 20 drives actuating spindle 42 synchronous axial system, make the sheetmetal group arcuately resistance track slip in it, to export varying voltage signal, feed back to controller, controller provides corresponding moving velocity direct current according to the value of setting, when realizing tiller rotation to different angles, can set different speed.
Above are only detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
