Abstract

The utility model provides a correcting belt with the flexible inner core, and the correcting belt comprises an inner core which can be glidingly held in an upper cover and a lower cover; the inner core includes an inserting groove, a positioning shaft and a lower bracket of the positioning shaft; an inserting key on a button can run through a sliding groove of the upper cover and is arranged in the inserting groove; the button is connected at one end of a spring, and either the upper cover or the lower cover is connected at the other end of the spring; a small gear wheel and a glue ring are arranged on the positioning shaft; a big gear wheel is arranged on the positioning shaft; the small gear wheel is meshed with the big gear wheel; a buckling button is arranged on the lower bracket; a buckling groove with a buckling station is arranged on the lower cover; the buckling button is held at the buckling station of the buckling groove during the process that the button drives the inner core to slide; the glue ring is arranged through the positioning shaft; the inner hole of the small gear wheel is in clearance connection with the glue ring; the button can drive the inner core in the upper cover and the lower cover to slide in the correcting belt, so as to be convenient for users to use the correcting belt; and a hollow cavity which is formed by the upper cover and the lower cover can effectively protect the inner core when the correcting belt is not used.

Description

A kind of correction band of scalable inner core

Technical field

The utility model relates to revises band, is meant a kind of correction band of scalable inner core especially.

Background technology

The inner core of revising band at present has being connected of various ways with the housing of revising band, because the activity form difference of inner core in revising the band housing, basic structure all is that the use cutting part of inner core directly exposes in housing outside or adds a protective cover, just can use the inner core correction after pulling up protective cover.If but protective cover is lost the inner core that can't protect correction to be with.

The utility model content

In view of this, the utility model is to provide a kind of correction band of scalable inner core, loses to solve above-mentioned protective cover, can't protect the problem of revising the band inner core.

For addressing the above problem, the utility model provides a kind of correction band of scalable inner core, comprising: slidably be held in the inner core in loam cake, the lower cover;

Described inner core comprises: the lower carriage with slot, locating shaft, locating shaft, the chute that slotting key on the button passes described loam cake is installed in the slot, button connects an end of spring, fixedly connected loam cake of the spring other end or lower cover, pinion and cushion rubber are installed on the locating shaft, gear wheel is installed, pinion and gear wheel engagement on the locating shaft; Described button drives inner core and compresses the chute slip of spring along described loam cake, takes the front end of described inner core the cavity of described loam cake, lower cover formation out of, and described inner core drives the front end of described inner core and regains in the cavity under the reduction elastic force effect of spring.

Preferably, have buckle on the described lower carriage, the described draw-in groove that covers down with band screens, button drives in the inner core sliding process, and buckle is held in the screens of draw-in groove.

Preferably, locating shaft holds installs described cushion rubber, and the interior interporal lacuna of described pinion is connected on the described cushion rubber.

The inner core that correction band in the utility model, button drive in loam cake, the lower cover slides, and revises band thereby be user-friendly to, and when not using, the cavity that loam cake, lower cover form can effectively be protected inner core.

The specific embodiment

For clearly demonstrating the technical scheme in the utility model, provide preferred embodiment below and be described with reference to the accompanying drawings.

In an embodiment, the lower carriage of revising band can be referring to Fig. 1, have locating shaft 51 and locating shaft 52 on the lower carriage, hold installation cushion rubber as shown in Figure 2 on the locating shaft 51, pinion is as shown in Figure 3 installed in the gap on cushion rubber, the inner hole sleeve of pinion is installed gear wheel as shown in Figure 4 on locating shaft 52 on the cushion rubber external diameter, form meshing relation between gear wheel and the pinion.Button as shown in Figure 5 is installed on the slot 53 of location,, is formed structure as shown in Figure 7 by the installation of the reference column on lower carriage upper bracket as shown in Figure 6.

Inner core shown in Figure 7 slidably is held in as shown in Figure 8 the lower cover, the fixing spring as shown in Figure 9 of slotting key on the button, the other end of spring is fixed on down and covers, and at last as shown in figure 10 loam cake and lower cover is fastened, and holding connection, button exposes outside the chute of loam cake.

In use, promote button, button drives inner core and stretches out from the cavity that loam cake, lower cover form, and the spring that connects is elongated or compression, and inner core slides in lower cover, and buckle 11 is held in the screens of draw-in groove 12 and holds, and can use this moment and revise band; After finishing using, promote button, button drive buckle 11 skids off from the screens of draw-in groove 12, and the spring retraction resets, and under the drive of spring reset process, inner core is withdrawn in the cavity of loam cake, lower cover formation, thus the inner core that protection correction is with.

For the correction band of being set forth among each embodiment of the utility model, all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
