Description
Technical field
The utility model easy-to-replaceable clockwork spring elastic force type painted scroll relates to a kind of display and demonstration equipment, especially a kind of painted scroll of being convenient to stretch.
Background technology
So-called traditional post stand is popular in recent years portable displaying equipment, its structure mainly comprises a shell, inside can be used for adorning the picture of rolling up, on the fixing in the enclosure cylinder that has an elastic force stretching device in the lower end of drawing, the upper end of drawing is fixed on is convenient to draw on the extension picture bar of picture, be base in use with the shell, fixing in the hole with vertical rod insertion shell, to hang the picture bar behind the extraction picture is fixed on the upright pole top, elastic force apparatus is tightened picture in the outer shell, will draw in the income shell by this elastic force again when receiving picture.Be a kind of being easy to carry about with one, show equipment easily.Elastic force apparatus notion wherein is to be mounted on torsion spring in the painted scroll one width of cloth picture is rolled to reach to reel purpose.
Its shortcoming is: 1, old picture need be taken off from painted scroll and extension picture bar when the client changes picture, will newly draw and change, cause maloperation easily, discharge the elastic force of pretension fully, and lose the post stand function, also might damage picture, and the picture assembling process is also extremely inconvenient.2, traditional post stand will be done the spring pretension when dispatching from the factory, and the client loads onto picture like this, and picture just can be taken in the shell, so that transportation is carried.But the pretension elastic force of picture is fixed, and the client is difficult to adjust elastic force because of the requirement of picture making length.Short picture is pine too, and long picture can too tightly cause drawing picture to be required great effort very much.3, the stress value curvilinear motion of torsion spring is very big, and is restive to the picture degree of tautness, also influences the effect of picture.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of easy-to-replaceable clockwork spring elastic force type painted scroll is provided, by using clockwork spring to reach the folding and unfolding picture, adjust the purpose of elastic force, simultaneously painted scroll is carried out unidirectional locking, painted scroll is easily taken, and the client can reach the purpose of changing picture easily by changing painted scroll, and is convenient, safety, fast.
Technical problem of the present utility model can solve by following technical proposals: a kind of easy-to-replaceable clockwork spring elastic force type painted scroll, picture is rolled up on painted scroll, comprise shell, be arranged at painted scroll and painted scroll rotating mechanism in the shell, painted scroll is made up of the axle core cap at stack shell and stack shell two ends, wherein, described stack shell is the hollow tube structure, described painted scroll rotating mechanism is by the clockwork spring tightening system with by ratchet, the unidirectional self-lock mechanism that ratchet constitutes forms, described clockwork spring tightening system is that clockwork spring one end is fixed in the unidirectional self-lock mechanism, the other end snaps onto on the going barrel, and going barrel is fixed on axle core cap one side that unidirectional self-lock mechanism is set.
In the utility model, provide a kind of unidirectional locked mechanism, specifically: described unidirectional self-lock mechanism is located at a side of painted scroll, the axle core cap is provided with a mesopore, around mesopore, be provided with two or more ratchets, be provided with a ratchet, ratchet and ratchet engagement in this end stack shell inboard.
On the such scheme basis, have on the described ratchet two or more with the axle core cap on the corresponding ratchet of ratchet, a side of ratchet is cast with square shaft, pass the mesopore of a core cap, opposite side is provided with the push rod of replacing spring, push rod shaft tool one slit, and clockwork spring one end is fixed in the slit.When rotating on the square shaft that is enclosed within ratchet with special instrument, because the interaction of ratchet and ratchet, clockwork spring only can not screw and can loosen, and plays the effect that tightens clockwork spring.
For ratchet can in time be resetted, described push rod is replaced a spring that is located in the going barrel, makes ratchet displacement vertically.
On the such scheme basis, described unidirectional self-lock mechanism is regulated by rotary spanner, comprises square hole post, spanner and muscle, wherein, the square hole post is fixed in shell end cap inboard, and spanner is set on the square hole post, and muscle is located at the root of square hole post, spanner is provided with the inclined-plane, when the inclined-plane rotates with spanner and muscle interact, rotary spanner is with the ratchet locking radial, promote ratchet simultaneously and move axially, cause ratchet and ratchet to disengage.At this moment, painted scroll just can freely rotate in the enclosure, thus when picture can be pulled out easily, rapid during rolling.
Insert in the square hole of square hole styletable head setting in order to allow square shaft be easier to, spanner is provided with a gathering sill, and the square shaft on the ratchet inserts in the square hole via gathering sill.
On the such scheme basis, described going barrel has one " protruding " font inner chamber, spring is positioned at the chamber of its bottom evagination, replaced by the ratchet push rod, also be provided with a U type hole on the going barrel shell, clockwork spring and ratchet are set in the going barrel inner chamber, and one on clockwork spring is fixed in the slit of ratchet push rod, and the other end button is solid in this U type hole.When changing picture and need painted scroll taken out in shell, spring plays an effect that resets, and is replacing ratchet and is moving axially, and returns original position, makes ratchet and ratchet engagement, and painted scroll is in the unidirectional self-lock state again.
Installing one baffle plate is set with baffle plate and clockwork spring successively on the ratchet push rod on the push rod, prevents that clockwork spring from blocking ratchet.
Described ratchet is sleeved in the going barrel.Make unidirectional locked mechanism combine compactness with the clockwork spring rotating mechanism.
Going barrel and stack shell make going barrel can relative motion not arranged with stack shell in the fixedly axle core cap one side close fit of unidirectional self-lock mechanism.
The utility model has the advantages that:
1, painted scroll has the unidirectional self-lock function, and is convenient especially when changing picture;
2, the unidirectional self-lock mechanism opening is easy, and is easy to use;
