Below in conjunction with drawings and Examples, the utility model is described in further detail.
The specific embodiment
As shown in Figure 3 and Figure 4, bill printer core comprises support 3 and the detachable member 4 being removably connected with support 3, between support 3 and detachable member 4, form paper feed passage, detachable member 4 is arranged on the front end of support 3, and paper cutter is arranged on the top of support 3 and detachable member 4.Support 3 comprises the openable pedestal 31 in bottom and is arranged on the side cover 33 of pedestal 31 sidewalls.
Rubber roll 41 is installed in detachable member 4, the middle part of rubber roll 41 is roll shaft 43, the two ends of roll shaft 43 are arranged on the installation position 32 on pedestal 31, one end of rubber roll 41 is provided with the gear 42 that receives driving force, rubber roll 41 rotates with the rotation of gear 42, and drives printing paper to move ahead with printing paper friction.
With reference to Fig. 5, Fig. 5 is another STRUCTURE DECOMPOSITION figure that bill printer core has omitted detachable member 4, operative gear and side cover 33.On support 31, be provided with the locked component of locking detachable member 4, locked component comprises rotating shaft 51, the first locking module and the second locking module, the first locking module comprises that hook member 52, axle sleeve 54 and torsion spring 56, the second locking module comprise hook member 53, axle sleeve 55 and torsion spring 57.Hook member 52 comprises that hook closes portion 523, guide hole 522 and torsion spring installing hole 521, and hook member 53 comprises that hook closes portion 523, guide hole 522, torsion spring installing hole 521 and press section 534, has fixed part 541(referring to Fig. 3 on axle sleeve 54), on axle sleeve 55, there is fixed part 551.
When locked component is installed, first rotating shaft 51 is passed in to guide hole 341 and the guide hole 342 on pedestal 31, because the both ends of rotating shaft 51 are set to non-circular, in the present embodiment, the end of rotating shaft 51 is the truncated cone-shaped with two sections, be understandable that rotating shaft 51 ends can be set to non-circular shape arbitrarily, so hook member 52 and hook member 53 are provided with the non-circular hole cooperatively interacting with rotating shaft 51 ends, it is respectively guide hole 522 and guide hole 532.Then, respectively hook member 52 and hook member 53 are arranged on the sidewall of left and right, and respectively guide hole 522 and guide hole 532 are enclosed within on two ends of rotating shaft 51.
Then, respectively axle sleeve 54 and axle sleeve 55 be enclosed within on two ends of rotating shaft 51 and lay respectively at the outside of hook member 52 and hook member 53.Subsequently, torsion spring 56 is enclosed within on axle sleeve 54, and an end of torsion spring 56 is fixed in the torsion spring installing hole 521 of hook member 52, the other end is fixed in the torsion spring installing hole 352 of pedestal 31, finally torsion spring 57 is enclosed within on axle sleeve 55, and an end of torsion spring 57 is fixed in the torsion spring installing hole 531 of hook member 53, the other end is fixed in the torsion spring installing hole 351 of pedestal 31.
When detachable member 4 is installed, apply external force to press section 534, make to hook that to close the opening of portion 533 corresponding with the guiding groove 361 on pedestal 31.Because the both ends of rotating shaft 51 are non-circular, hook the portion of closing 533 and can take rotating shaft 51 and rotate for axle core, and hook to close the same guiding groove 362 with on pedestal 31 of the opening of portion 533 corresponding.After roll shaft 43 is in place by guiding groove 361 and guiding groove 362, the external force of release to press section 534, hook member 52 rotates and makes to hook the portion of closing 523 and hook and close with roll shaft 43 under torsion spring 56 resilient force, hook member 53 rotates and makes to hook the portion of closing 533 and hook and close with roll shaft 43 under torsion spring 57 resilient force, thereby realizes the locking to detachable member 4.
When needs are dismantled detachable member 4, applying external force 534 rotates hook member 52 and hook member 53 to press section, then hook the locking that the portion of closing 523 and roll shaft 43 depart to remove 52 pairs of detachable members 4 of hook member, hook the locking that the portion of closing 533 and roll shaft 43 depart to remove 53 pairs of detachable members 4 of hook member simultaneously, can realize the dismounting of detachable member 4, the external force of release to press section 534, hook member 52 and hook member 53 go to original position at the resilient force backspin of torsion spring.
From such scheme, by the outside at pedestal, locked component is carried out to installation or removal, make operation have more simplicity, be conducive to improve user of service's efficiency, and respectively torsion spring 56 and torsion spring 57 are fixed by fixed part 541 and fixed part 542, make torsion spring difficult drop-off when there is deformation, guaranteed the stability of bill printer core work.
