Description
Technical field
The present invention relates to a kind of portable medical orthopedic dynamic system motor rotating speed adjusting mechanism, particularly a kind of motor speed governor motion of the handheld drill for medical field.
Background technology
The motor speed governor motion more complicated of existing medical portable medical orthopedic dynamic system (as bone drill), and regulate inconvenient, such as medical bone drill disclosed in CN103654910A, drill bit rear portion is fixedly connected with housing through bearing, rotating shaft is provided with in pistol-like housing, rotating shaft is provided with and rotates forward bevel gear and unilateral bearing, rotating shaft two ends are connected with housing respectively, unilateral bearing is fixed in driving wheel, corresponding driving wheel side is provided with cone pinion, cone pinion is fixedly connected with drill bit, driving wheel lower end is fixedly connected with trigger, trigger is connected with housing through back-moving spring.This motor governor motion structure is very complicated.
In addition, in Clinical practice, the speed governing trigger of part motor governor motion in use, active force due to user can not ensure to keep concentric with the mechanism of leading, cause speed governing trigger easily and produces between parts around and rub, speed governing trigger is moved smoothly, easily produces noise, cause governor motion underaction, even to some unnecessary treatments miseries that patient brings.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide that a kind of structure is simple, trigger is regulated the speed smooth and easy, portable medical orthopedic dynamic system motor rotating speed adjusting mechanism that governor motion noise is little flexibly.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of portable medical orthopedic dynamic system motor rotating speed adjusting mechanism, comprise trigger, O type packing ring, fairlead, flexible member and steady pin, wherein trigger body is provided with pin-and-hole, trigger body is through fairlead, flexible member is nested into the foot of trigger body, the top internal perisporium of fairlead is provided with groove, O type packing ring can be placed in the groove on the top internal perisporium of fairlead, when being arranged on trigger body by fairlead, O type packing ring is arranged between trigger body and fairlead.And when fairlead is arranged on after on trigger body, steady pin is inserted in the pin-and-hole on trigger body.Can be installed on motor driver after above-mentioned motor speed governor motion assembling.Speed governing trigger is movable under the guiding of fairlead, realizes electric machine speed regulation.
The present invention adopts speed governing trigger, fairlead, the set-up mode of O type packing ring is beneficial to fast trigger and moves forward and backward under the guiding of fairlead, and owing to there is fit clearance between speed governing trigger and fairlead, if the external force acted on speed governing trigger is not concentric with fairlead, speed governing trigger will be caused tilted at fairlead, because the contact between speed governing trigger and fairlead can make the frictional resistance between speed governing trigger and fairlead increase, thus the movement of speed governing trigger in fairlead is become have some setbacks, in mechanism in the present invention, owing to being provided with elastic O type packing ring on the internal perisporium of fairlead, under the elastic force effect of elastic O type packing ring, speed governing trigger and fairlead remain concentric, thus the frictional resistance that the movement of speed governing trigger receives is consistent, avoid between metal and metal due to phenomenon of having the hiccups that frictional force causes, ensure that speed governing trigger moves smooth and easy.
The present invention, owing to adopting said structure, has that structure is simple, motor speed flexible adjustment is smooth and easy, it is convenient to control, is easy to alleviate the advantages such as patient suffering.
