A kind of pressure head stretching or the mechanism retracted and the takeup type stationery containing the mechanism

Technical field

The invention belongs to a kind of takeup type stationery, it is related to pressure head stretching or the improvement of retracted arrangement in this product structure, More specifically, it is a kind of coincide with another slope in moving process using slope and provides to pressure head by compressing except active force Mechanism is adapted to such as correction tape, color ribbon and double faced adhesive tape.

Background technique

Correction tape, color ribbon and double faced adhesive tape are common stationery, they be attached in base band by function diaphragm, and It is supplied to user in the form of winding, when use need to be realized by the device of winding release, diaphragm removing and base band recycling, day Often in life, for people by these winding together with their device, traditionally still crying is correction tape, color ribbon and double faced adhesive tape.

In general, in these devices, being configured with feed roller, take-up pulley and pressure head, winding is released by feed roller, by pressure head It is recycled afterwards by take-up pulley, when pressure head passes through pressing winding and drives winding mobile, feed roller will rotate and release winding, together When, feed roller drives take-up pulley rotation, and under pressure head pressing effect, function diaphragm is stripped and is covered on paper for winding, Base band is then rolled under take-up pulley rotary action and is recycled.

In traditional takeup type stationery, correction tape, color ribbon and double faced adhesive tape polyphyly, which use, allows pressure head to retract from opening It can prevent pressure head from breaking in falling so that collection and protection are implemented in the winding to pressure head and at pressure head to enclosure interior And winding at pressure head is prevented to be stained with dust.

Currently, pressure head is stretched out from shell nozzle or retracted mainly using two kinds of structure types: one is pressure heads and sending and receiving band Wheel moves together, this necessarily causes internal volume to propose biggish requirement；Another kind is that pressure head separates and only with sending and receiving belt wheel Vertical movement, but there are problems that the folding that pressure head is retracted into winding at shell inner ram must be solved.

In addition, in the structure that pressure head is separated with sending and receiving belt wheel, the stretching of pressure head or to retract be by using such as shifting block Component drives, these components usually with pressure head synchronizing moving, and from these components temporarily limited and to pressure head provide by To the active force removed when pressure.

Furthermore in the structure that pressure head is separated with sending and receiving belt wheel, folded rod is usually to be fixed on pressure head or pressure head fixing piece On, interim folding is carried out to winding by folded rod while being retracted into enclosure interior using pressure head.

The document being set forth below can reflect out these problems:

Chinese utility model patent 201320486041.7 discloses a kind of correction tape, it is controlled using pressing mechanism and spring Tongue piece processed is stretched out or is retracted from opening together with receipts tape-feed, and provides support force to tongue piece by actuating rod from pressing mechanism.

Chinese invention patent 201110458449.9 discloses a kind of correction tape, its pressure mouth is connected by connector and adjusting knob Together, cooperated using the locating piece of adjusting knob and the locating notch in housing side hole, to realize pressure mouth in the extended state Stability, meanwhile, interim folding is carried out to winding by revolving part.

Chinese invention patent 2015105574859 discloses a kind of correction tape, its tongue piece is fixed on moving member, moving member Being stirred by shifting block can drive tongue piece to stretch out from shell nozzle, constituted and stopped to the block on moving member using the block on shell, Moving member can temporarily be limited, meet the pressing operation of tongue piece, meanwhile, interim folding can be carried out to winding by bar and strut.

Chinese invention application 201610955226.6 discloses the rotating mechanism that pressure head is stretched out or retracted in a kind of stationery, it Pressure head can be respectively enterd two stop track of shell from its two prominent bar and provide supporting for compression to pressure head and remove active force, meanwhile, by pressing Pole on head carries out interim folding to winding.

In these structures, in order to allow pressure head, enclosure interior is retracted in winding at pressure head, and will pulled back from the volume of enclosure interior Band folding is got up, and structure design becomes redundancy or complexity, and also occupies more space, in addition, by pressure head or pressure head Folded rod on fixing piece carries out folding to winding, and there are still be difficult to the problem of tightening winding.

Summary of the invention

The invention aims to provide a kind of pressure head stretching or the mechanism retracted and the takeup type stationery containing the mechanism, It can be generated and be coincide with pedestal slope under shifting block drive by the slope of moving part in mechanism, and further moved using shifting block to press from both sides Two slopes are pressed, support pedestal can to compression is provided by moving part except active force by two slopes, to obtain a kind of compression offer To the new paragon for removing active force.

The purpose of the present invention also provides a kind of pressure head stretching or the mechanism retracted and the takeup type stationery containing the mechanism, Pressure head is flexibly connected with by moving part composition in mechanism, and folded rod is fixed on by moving part, so as to pressure head be retracted into base interior by Moving part can continue to move under shifting block drive, further tighten winding.

The mechanism that pressure head of the invention is stretched out or retracted is realized by following scheme:

The mechanism that a kind of pressure head is stretched out or retracted, its main feature is that: including shifting block, by moving part and pedestal, driven by moving part Movable press head；Wherein: the pedestal hole containing mounting hole and moving hole is provided on pedestal, pedestal is distinguished in moving hole two sides There is the straight rail formed by flange, straight rail forms pedestal slope in front end face；It is free in being formed with front end in frame by moving part Wraping plate is provided with the wraping plate hole containing mounting hole and moving hole on wraping plate, and wraping plate bottom is in moving hole two sides along rear end face It is formed with wraping plate slope, wraping plate is formed with behind mounting hole and retracts push rod；Shifting block be rendered as it is I-shaped, have top cross bar, Bottom bar and intermediate vertical bar；It being placed on pedestal by moving part, wraping plate bottom moving hole two sides edge is located in two straight rails, and The bottom bar of shifting block passes through the mounting hole in pedestal hole and wraping plate hole, and the intermediate vertical bar of shifting block is then located at pedestal hole and sticks up In lath hole, and wraping plate slope and retracts push rod and just insert in respectively at the two sides of bottom bar of shifting block.

Then, the bottom bar of shifting block is due to being no longer detached from mounting hole, together by wraping plate slope and the blocking for retracting push rod When, top cross bar can be sandwiched in wherein together with bottom bar by pedestal and by moving part.

In this way, shifting block will act on wraping plate slope by bottom bar and force by moving part to Forward when shifting block moves forward It is dynamic, meanwhile, wraping plate moving hole two sides are presented wraping plate front end and are upturned, work as wraping plate along due to the effect by two straight rails When slope is moved to pedestal slope, wraping plate moving hole two sides are along the effect for being no longer influenced by two straight rails, and then, wraping plate front end is no longer It tilts and resets, so that wraping plate hole two sides is in same level along with pedestal slope, and wraping plate slope and pedestal slope are kissed It closes, then, shifting block can be continued to move along relative to wraping plate, and shifting block bottom bar is made to be located at wraping plate slope and pedestal slope On, wraping plate slope and pedestal slope are clamped, so as to be supported from pedestal to by moving part offer compression except active force.

In addition, when shifting block moves backward, shifting block will leave wraping plate slope and pedestal slope, no longer to wraping plate slope and base Seat slope is clamped, meanwhile, shifting block is moved backward with respect to wraping plate, and is contacted with push rod is retracted, and then, shifting block is pushed away by retracting Bar effect is moved backward by moving part, and wraping plate slope up over pedestal slope and moves backward under the action of pedestal slope.

It is preferred that forming inclined-plane with the contact position on wraping plate slope on bottom bar in above scheme.In this way, can by When moving part moves forward two slopes and coincide, the inclined-plane by the effect to wraping plate slope, wraping plate slope can be generated one to Under component, which can force wraping plate slope and pedestal slope to coincide, avoid wraping plate due to being in regularly to overcome Idle state is also easy to produce the deformation being upturned and wraping plate slope and pedestal slope is caused to be not easy identical problem, and can guarantee Subsequent shifting block can be moved smoothly and be in the anastomosis on wraping plate slope and pedestal slope.

The mechanism that the invention pressure head is stretched out or retracted, for pressure head during stretching, shifting block not only can be with wraping plate slope Contact provides power for the forward movement by moving part, and then shifting block can also be mobile relative to wraping plate, be wraping plate slope with The active force that the identical offer on pedestal slope clamps act on pedestal can to being supported to remove when being provided compression by moving part by two slopes Power.

The mechanism that the invention pressure head is stretched out or retracted, in fall back process, shifting block can also move pressure head relative to wraping plate It moves and is contacted with push rod is retracted, power is provided to be moved backward by moving part, to enable mechanism normal operation.

The mechanism that pressure head of the present invention is stretched out or retracted, its inclined-plane of bottom bar produces wraping plate slope in moving process Downward active force can cope with when wraping plate slope coincide with pedestal slope and easily occur since wraping plate is in idle state regularly Be upturned deformation the problem of, so as to guarantee operation it is steady and improve organisation operations reliability.

The mechanism that this pressure head is stretched out or retracted, the movement on wraping plate slope is tied up to above pedestal slope and is carried out, in this way, pressure head is stretched Out or the control retracted can be limited in lesser spatial dimension, be simplified product structure, in particular, being conducive to produce Product further minimize.

It is preferred that pressure head is flexibly connected with by moving part composition in above scheme, pressure head is pushed or pull on by moving part and is stretched out Or pedestal is retracted, and folded rod is fixed on by moving part.

In this way, having a stroke by moving part relative to pressure head by moving part before pushing pressure head, conversely, being drawn by moving part Before dynamic head, also there is a stroke by moving part relative to pressure head, since folding leverage is fixed on by moving part, then, is pressing In head fall back process, the stroke of folded rod will be greater than the stroke of pressure head, thus folded rod has and receives the winding at pressure head completely The ability of folding, winding is at the state of tightening when pressure head being made to retract pedestal, be better protected from winding due to relaxation be easy by Curling is caused to cause confusion to towing.

It is preferred that shifting block vertical bar is formed with middle transverse rod in above scheme, middle transverse rod free end is formed down convex Edge, pedestal form platform, and the both ends Yu Pingtai have end.

In this way, no matter pressure head stretching is collected for using or retracting pedestal, flange can be stuck in both ends respectively and It is fixed temporarily, generates shifting block no longer and move freely.
