[0046] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0047] Embodiment 1

[0048] A correction tape, such as Figure 1-Figure 5 As shown, it includes a correction tape shell 1 and a correction tape refill 2. The correction tape refill 2 is installed in the correction tape shell. The correction tape shell 1 includes a first half shell 11 and a second half shell 12 that are buckled together by a buckle structure. One end of the first half shell 11 and the second half shell 12 is provided with a nozzle opening 13, and the end of the first half shell 11 away from the nozzle opening 13 and the end of the second half shell 12 away from the nozzle opening 13 are pivotally connected (i.e., hinged) together by a pin. The above-mentioned buckle structure can be a conventional structure in the industry such as a slot buckle. In addition, the correction tape shell 1 can also be other common structures in the industry.

[0049] The correction tape refill 2 includes a refill base plate 21 and a refill member 3. One end of the refill base plate 21 is hinged to the hinged position of the first half shell 11 and the second half shell 12. The refill member 3 includes a refill top plate 31, a pressure nozzle 32, a take-up wheel 33 and a take-out wheel 34 installed on the refill top plate 31, and a correction tape body 35. The correction tape body 35 bypasses the pressure nozzle 32, and the two ends of the correction tape body 35 are respectively wound around the take-up wheel 34 and the take-up wheel 33. The refill base plate 21 and the refill member 3 are buckled together in a detachable manner, such as by the cooperation of a convex column and a hollow column. In addition to the cooperation of the convex column and the hollow column, other conventional buckle structures can also be used. A driving gear 41 is provided on the refill base plate 21 at a position corresponding to the axis of the take-out wheel 34, and a driven gear coaxial with the take-up wheel 33 is provided on the end surface of the take-up wheel 33 corresponding to the refill base plate 21. A transition gear 43 is provided on the replacement core bottom plate 21 at a position between the driving gear 41 and the corresponding driven gear. The transition gear 43 of the correction tape replacement core 2 is meshed with the driving gear 41 and the driven gear respectively, that is, the driving gear 41 and the driven gear are connected in a transmission manner. In this way, even if the belt delivery wheel 34 and the belt take-up wheel 33 are in the unlocked state described below, self-locking can be achieved through the cooperation of the above-mentioned gear set (i.e., the driving gear, the driven gear and the transition gear) to prevent the belt from being loosened significantly. It can be seen from this that the above-mentioned gear set not only has a transmission function, but also has a meshing limiting function.

[0050] The outgoing pulley 34 is provided with a first limiting portion, the take-up pulley 33 is provided with a second limiting portion, the replacement core top plate 31 is provided with a first elastic rib buckle 51 and a second elastic rib buckle 52, the end of the first elastic rib buckle 51 is buckled with the first limiting portion, and the end of the second elastic rib buckle 52 is buckled with the second limiting portion. The correction tape housing 1 is provided with a disengagement guide groove 6 at a position corresponding to the first elastic rib buckle 51 and the second elastic rib buckle 52 to promote the elastic deformation of the first elastic rib buckle 51 to separate from the first limiting portion, and / or to promote the elastic deformation of the second elastic rib buckle 52 to separate from the second limiting portion.

[0051] Preferably, the first limiting portion is a first toothed circumferential portion, and the second limiting portion is a second toothed circumferential portion. The first toothed circumferential portion may be an inner circumferential toothed portion or an outer circumferential toothed portion. A partial toothed portion or a closed loop continuous toothed portion. In this embodiment, the first toothed circumferential portion is a first toothed disc 36 coaxial with the outgoing pulley 34, and is an outer circumferential toothed portion. The second toothed circumferential portion is a second toothed disc 37 coaxial with the take-up pulley 33, and is an outer circumferential toothed portion. The first toothed disc 36 is fixed on the end face of the outgoing pulley 34 corresponding to the replacement core top plate 31, and the second toothed disc 37 is fixed on the end face of the take-up pulley 33 corresponding to the replacement core top plate 31. The first toothed disc 36 is located between the outgoing pulley 34 and the replacement core top plate 31, and the second toothed disc 37 is located between the take-up pulley 33 and the replacement core top plate 31. The above-mentioned driven gear and the second toothed disc 37 are arranged on the two end faces of the take-up pulley 33 opposite to each other.

[0052] The refill top plate 31 is provided with a movable groove 7 at a position corresponding to the center axis of the outgoing belt wheel 34 and the center axis of the take-up belt wheel 33. The first elastic rib buckle 51 has a connection end and a free end, and the second elastic rib buckle 52 has a connection end and a free end. The free end of the first elastic rib buckle 51 is provided with a convex grain 511 which is conducive to engaging with the tooth profile of the first toothed circular disk 36, and the free end of the second elastic rib buckle 52 is provided with a convex grain 521 which is conducive to engaging with the tooth profile of the second toothed circular disk 37. The connection end of the first elastic rib buckle 51 and the connection end of the second elastic rib buckle 52 are both connected to the groove wall of the movable groove 7. The first elastic rib buckle 51 is arranged along the tangent direction of the first toothed circular disk 36 or close to the tangent direction. The second elastic rib buckle 52 is arranged along the tangent direction of the second toothed circular disk 37 or close to the tangent direction. The shape and size of the movable groove 7 only need to be compatible with the shape, size, elastic range of activity, etc. of the first elastic rib buckle 51 and the second elastic rib buckle 52. The first elastic rib buckle 51 and the second elastic rib buckle 52 are axially symmetrically arranged. Looking from the connecting end of the first elastic rib buckle 51 or the second elastic rib buckle 52 to the free end, the first elastic rib buckle 51 and the second elastic rib buckle 52 are in an inverted figure eight shape. The disengagement guide groove 6 is arranged corresponding to the first elastic rib buckle 51 and the second elastic rib buckle 52. The disengagement guide groove 6 is correspondingly figure eight-shaped. The disengagement guide groove 6 has an enlarged diameter section 61 and a reduced diameter section 62, and the enlarged diameter section 61 and the reduced diameter section 62 are smoothly connected. The disengagement guide groove 6 is arranged on the inner side wall of the first half shell 11, and the enlarged diameter section 61 passes through the connecting end edge of the first half shell 11 and the second half shell 12. It should be noted that tooth-shaped teeth are convexly provided on the mating surface of the protrusion 511 and the protrusion 521 with the toothed disc to facilitate engagement. In addition, the protrusions 511 and 521 need to protrude from the outer side surface of the refill top plate 31 and extend into the release guide groove 6 to abut against the groove side wall of the reduced diameter section 62 .

[0053] by Figure 5The state of the refill 3 is an initial state, in which the convex grain 511 of the first elastic rib buckle 51 is engaged with the first toothed disc 36, thereby limiting the output pulley 34 fixed with the first toothed disc 36 from rotating in the direction that causes the correction belt body 35 mounted on the output pulley 34 to loosen, thereby preventing the correction belt body 35 from loosening, that is, the output pulley 34 is in a locked wheel state. Similarly, the convex grain 521 of the second elastic rib buckle 52 is engaged with the second toothed disc 37, thereby limiting the take-up pulley 33 fixed with the second toothed disc 37 from rotating in the direction that causes the correction belt body 35 on the take-up pulley 33 to loosen, thereby preventing the correction belt body 35 from loosening, that is, the take-up pulley 33 is in a locked wheel state. When both the output pulley 34 and the take-up pulley 33 of the refill 3 are in the locked wheel state, the refill 3 will not easily loosen even if it is in a state such as transportation. When it is necessary to use or replace the first shell 1 and the second shell 2, the first shell 1 and the second shell 2 are opened to form an opening, and the replacement core 3 is installed on the replacement core bottom plate 21 through the opening. Then the opening between the first shell 11 and the second shell 12 is closed, and the replacement core 3 is installed on the replacement core bottom plate 21. Figure 2 As shown, the convex grain 511 of the first elastic rib buckle 51 and the convex grain 521 of the second elastic rib buckle 52 are inserted and slid from the enlarged diameter section 61 of the release guide groove 6 to the reduced diameter section 62, and then the first elastic rib buckle 51 and the second elastic rib buckle 52 are squeezed and elastically deformed, and the convex grain 511 of the first elastic rib buckle 51 is separated from the first toothed disc 36, that is, the belt-out wheel 34 is in an unlocked state, and the convex grain 521 of the second elastic rib buckle 52 is separated from the second toothed disc 37, that is, the belt-receiving wheel 33 is in an unlocked state. During the use of the correction tape, the convex grain 511 of the first elastic rib buckle 51 and the second elastic rib buckle 52 are always confined in the reduced diameter section 62, and the belt-out wheel 34 and the belt-receiving wheel 33 are always in an unlocked state, so as to complete the use of the correction tape's tape-scratching function.
