Description
Technical field
The utility model relates to File Technology fields, relate in particular to a kind of into a mechanism.
Background technique
Belong in common penknife into a mechanism and compares Conventional mechanisms, technical principle all comparative maturities.Briefly, into pen
Mechanism mainly includes bracket, turntable, shaft and the runner of pen clip, and pencil needs to be in not into mechanism after fining away when work
It is shaft bounce that work or halted state, which are the scheme of this present technical effect in the prior art, although this structure property
Can be good, but shaft frequently beats and can generate bigger noise in actual use, influences using effect.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of structure, reliable and noise is lesser into a mechanism.
The technical scheme in the invention for solving the above technical problem is: into a mechanism, it include bracket, turntable,
Shaft, gear and clip wheel, wherein the shaft is rack-mount by support arm, and the gear and clip wheel is pacified
In shaft, the turntable is equipped with protrusion, and protrusion has the shape that engage with the teeth of gear, the gear with turn
Temporary lock mechanism is equipped between axis.
The turntable is equipped with pillar, and the rubber pad is equipped with location hole, and the rubber pad passes through location hole
It covers and is positioned on pillar.
Temporary lock mechanism is equipped between the gear and shaft.
The temporary lock mechanism is that shaft is equipped with block, and gear is clipped between support arm and block, block and tooth
Equal waveform engaging groove between end face is taken turns, block and gear are engaged by engaging groove between the two and be close to.
Axle sleeve is additionally provided in the shaft, gear is mounted on axle sleeve.
The axle sleeve and gear is structure as a whole.
The other end of the shaft is equipped with position limiting structure, and clip wheel is between position limiting structure and block.
The position limiting structure is more along the circumferentially equally distributed strip of shaft, and the strip turns from shaft tail portion edge
Height gradually increases when axis is axially extending.
Compared with the prior art, the utility model has the following advantages: changing the working principle of shaft, when pencil is fined away not
When needing to advance, the stagnation mode of shaft is no longer completed by shaft bounce, but by the teeth of gear by with rubber pad
On salient point extruding slip over, cause gear be no longer able to drive shaft rotation, by improve, in shaft improve waveform engagement
Slot, when clip wheel, which is no longer able to conveying pencil, to advance, gear does not have the effect for driving shaft, and dual fail-safe guarantees that shaft will not turn
Dynamic, whole work process is more smooth, does not beat, it is possible to prevente effectively from noise.

Specific embodiment
As shown in figs. 1-7, for the utility model into a mechanism, it includes bracket 1, turntable 2, shaft 3, gear 4 and clip wheel
5, close with conventional structure, wherein the shaft 3 is mounted on bracket 1 by support arm 6, the gear 4 and clip wheel 5 are equal
Be mounted in shaft 3, the utility model the difference is that: the turntable 2 be equipped with protrusion 8, protrusion 8 have and gear 4
Teeth engagement shape, between the gear 4 and shaft 3 be equipped with temporary lock mechanism.Wherein, the meaning of temporary lock mechanism
Think of is to be typically in locking state, but silk ribbon attached to an official seal or a medal external force can be in releasing orientation.Gear guarantees turntable energy with engaging for turntable
Enough smoothly band moving gears rotate, and then realize and drive shaft rotation, realize into a function.When pencil sharper is played, pencil is no longer able to
To advance, shaft, which is just obstructed, to be rotated, and gear does not also rotate, and turntable is also rotating, and salient point is just unable to drive gear rotation,
Temporary lock mechanism would be at releasing orientation, and gear and shaft is made to relatively rotate, and such whole system is just at
Smooth state, pencil keeps stablizing, and the external world is applied to the rotation of turntable without stagnation.
The temporary lock mechanism specific structure is as follows: shaft 3 is equipped with block 11, and gear 4 is clipped in support arm 6 and gear
Between block 11, equal waveform engaging groove 12 between 4 end face of block 11 and gear, block 11 and gear 4 pass through nibbling between the two
The engagement of slot 12 is closed to be close to.Under normal circumstances, shaft rotation is able to drive by the engagement of waveform engaging groove between block and gear,
It is considered as locking state, when shaft rotation is obstructed, waveform engaging groove is considered as releasing orientation when relatively rotating.
Gear structure is further improved, is additionally provided with axle sleeve 13 in the shaft 3, gear 4 is mounted on axle sleeve 13, is
Consider that the axle sleeve 13 and gear 4 are structure as a whole convenient for manufacturing, saving the factors such as cost and structure be reliable.Axle sleeve can be with
Guarantee that gear can be more stable with the cooperation of shaft, gear can either be kept not shake, it is also ensured that gear can
Smoothly relatively rotate with shaft.
Preferably, the other end of the shaft 3 is equipped with position limiting structure, clip wheel 5 be located at position limiting structure and block 11 it
Between.This structure is the mounting means and structure to improve clip wheel.Specifically, the position limiting structure is more along shaft 3
Circumferential equally distributed strip 15, height gradually increases when the strip 15 is axially extending along shaft 3 from 3 tail portion of shaft.It is long
Item can guarantee that clip wheel stabilization does not move axially, and strip height change is convenient for clip wheel in the tapered structure of shaft shape
Installation.
It is a part of entire penknife into mechanism, other devices will drive turntable rotation when work, then sliding tooth
Wheel realizes shaft rotation, can thus pencil be driven to advance.After pencil is fined away, pencil can not just be moved on, at this moment
The rotation of shaft is just hindered, and the rotation of gear is also just hindered, and turntable is also by outer power drive, this driving force meeting
Relative dislocation rotation will occur for driving waveform engaging groove, realize the idle running effect of turntable, engage slot structure by waveform
It realizes that shaft and gear are detached from, guarantees the reliable and stable and low noise of this structure.
