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 utility model solve above-mentioned technical problem use into a mechanism include bracket, turntable, shaft, gear and folder Wheel, wherein the shaft is rack-mount by support arm, and the gear and clip wheel is installed in shaft, described Turntable be equipped with elastomeric pad, elastomeric pad is equipped with protrusion, and protrusion has the shape that engages with the teeth of gear, described Temporary lock mechanism is equipped between gear and shaft.

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 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 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 Figure 1-10 shows, 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, and temporary lock machine is equipped between the gear 4 and shaft 3 Structure.

Gear guarantees that turntable can smoothly band moving gear rotate with engaging for elastomeric pad, and then realizes and shaft is driven to turn It is dynamic, it realizes into a function.When pencil sharper is played, pencil is no longer able to advance, and shaft, which is just obstructed, to be rotated, and gear does not also turn It is dynamic, and turntable is also rotating, the extruding that at this moment the convex point of elastomeric pad receives gear teeth tooth is shunk, and teeth are slipped over from salient point, Realize the function that turntable rotates and shaft is motionless, temporary lock mechanism unlocks at the same time, makes that phase occurs between gear and shaft To rotation, salient point compressive deformation and the dual fail-safe of temporary lock mechanism act on guarantee that entire mechanism stable is reliable and does not make an uproar simultaneously Sound or noise are greatly reduced.

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.

Wherein, above-mentioned temporary lock mechanism, which is meant, is typically in locking state, but silk ribbon attached to an official seal or a medal external force can be in pine Open state.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, 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.

This structural reliability or inadequate is depended merely on, temporary lock mechanism is also set up in shaft, is engaged by waveform Slot structure realizes that shaft is detached from again with gear, and dual fail-safe guarantees the reliable and stable and low noise of this structure.
