Abstract

The technical scheme in the invention for solving the above technical problem is: into a mechanism, it includes bracket, turntable, shaft, gear and clip wheel, wherein, the shaft is rack-mount by support arm, the gear and clip wheel is installed in shaft, the turntable is equipped with elastomeric pad, and elastomeric pad is equipped with protrusion, and protrusion has the shape engaged with the teeth of gear.Change the working principle of shaft, when pencil sharpening does not need to advance, the stagnation mode of shaft is no longer completed by shaft bounce, but by the teeth of gear by being slipped over the salient point extruding on elastomeric pad, gear is caused to be no longer able to drive shaft rotation, pass through improvement, waveform engaging groove is improved in shaft, 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 not can rotate, and whole work process is more smooth, it does not beat, it is possible to prevente effectively from noise.

Description

Into a mechanism

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 elastomeric pad, and elastomeric pad is equipped with protrusion, and protrusion has nibbles with the teeth of gear The shape of conjunction.

The turntable is equipped with pillar, and the elastomeric pad is equipped with location hole, and it is fixed that the elastomeric pad passes through Position hole is covered to be positioned on pillar.

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 elastic cushion The salient point extruding of on piece slips over, and gear is caused to be no longer able to drive shaft rotation, by improving, improves waveform in shaft and nibbles Slot is closed, 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 Rotation, 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 is equipped with elastomeric pad 7, sets on elastomeric pad 7 There is protrusion 8, protrusion 8 has the shape engaged with the teeth of gear 4.Gear guarantees that turntable can be smooth with engaging for elastomeric pad Band moving gear rotates, and then realizes and drive shaft rotation, realizes into a function.When pencil sharper is played, pencil is no longer able to advance, and turns Axis, which is just obstructed, to be rotated, and gear does not also rotate, and turntable is also rotating, and at this moment the convex point of elastomeric pad receives gear teeth tooth Extruding shrink, teeth slip over from salient point, realize turntable rotation and the motionless function of shaft.

Improvement has also been made in the installation rock-steady structure of elastomeric pad, and the turntable 2 is equipped with pillar 9, the elastic cushion Piece 7 is equipped with location hole 10, and the elastomeric pad 7 is positioned on pillar 9 by 10 sets of location hole.

Preferably, being additionally provided with position limiting structure in the shaft 3, clip wheel 5 is between position limiting structure and gear 4.Tool For body, the position limiting structure is more along the circumferential equally distributed strip 15 of shaft 3, and the strip 15 is from 3 tail of shaft Height gradually increases (this point is from attached drawing 7 it can be seen that coming) when portion is axially extending along shaft 3.Strip can guarantee that clip wheel is steady It is fixed not move axially, and strip height change is installed in the tapered structure of shaft shape convenient for clip wheel.

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, also by outer power drive, this will lead to tooth Wheel is squeezed with the salient point on elastomeric pad, and the elasticity of last resort salient point, gear remains stationary and turntable persistently rotates.
