Description

Technical Field

[0001] The invention relates to the technical field of winding type stationery, in particular to an improved winding type stationery. Background Art

[0002] Commonly used roll-up stationery includes correction tape and double-sided tape. They are attached to the tape body with a functional film and are provided to users in a rolled form. When in use, they require a device to release the tape body, peel off the film, and recycle the tape body.

[0003] A Chinese invention patent (application number: CN201710701473.8) discloses an improved soft film push nozzle correction tape. Although the correction tape realizes the function of the transfer head and the tape body extending and retracting together and the nozzle opening and closing accordingly, the correction tape has the following problems during use: during use, when the tape body is being scratched, the inner core sliding part is subjected to the pressure of the user when scratching the tape, and the transfer head and the inner core sliding part cannot bear the force of the correction tape scratching, causing the transfer head and the inner core sliding part to slide back, affecting the scratching process. The correction tape quality is affected, which makes it difficult to complete the correction tape marking operation smoothly; on the other hand, the correction tape is connected to one end of the soft film through the operating part, and the sliding guide ribs and the elastic rib buckle cooperate with the other end of the soft film. At the same time, a nozzle groove is opened in the middle of the soft film.

DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] For the convenience of description, Figure 6 and Figure 7 The orientation shown is a reference orientation, where the orientation of the push button 4 (described in detail below) is upward, and the orientation of the push button 4 (described in detail below) is downward; the inner cavity of the positioning housing 1 (described in detail below) is inside, and the orientation of the push button 4 (described in detail below) is outside.

[0027] Reference Figures 1 to 7

[0028] An improved winding stationery comprises a housing 1, an inner core slide 2 movably arranged in the housing 1, the housing 1 comprising a first housing 11 and a second housing 12 which are relatively buckled together in a detachable manner through a snap-fit ​​structure, a groove track 13 is arranged on the opposite side of the first housing 11 and / or the second housing 12 in the length direction, and a slide bar 21 which is adapted to the groove track 13 and moves in the groove track 13 is arranged on the side of the inner core slide 2 corresponding to the first housing 11 and / or the second housing 12. Preferably, the groove track 13 and the slide bar 21 can be arranged in multiple groups, and of course the groove track 13 and the slide bar 21 are arranged one by one, which is conducive to the inner core slide 2 sliding back and forth in the housing 1, so that the inner core slide 2 can slide along the length direction of the housing 1 under the guidance of the groove track 13 and the slide bar 21, so that the transfer head 22 (which will be described in detail below) which moves with the sliding of the inner core slide 2 is extended out of the housing 1 or retracted into the housing 1.

[0029] The shell 1 is provided with a nozzle 14 for a transfer head 22 at one end along its length direction, and a belt retracting and releasing device is provided on the inner core sliding member 2, and the belt retracting and releasing device includes a transfer head 22 and a belt delivery wheel and a belt retracting wheel that are meshed and connected to each other. The transfer head 22 is provided at one end of the inner core sliding member 2, and the transfer head 22 is connected to the inner core sliding member 2 in an integral or assembled manner. The connection relationship between the transfer head 22 and the inner core sliding member 2 is a conventional connection relationship, which will not be described in detail here. The transfer head 22 is movably mounted at the nozzle 14. A belt body is wound around the transfer head 22, the belt delivery wheel and the belt retracting wheel, and the transfer head 22 is correspondingly installed at the nozzle 14, and the nozzle tip operating end of the transfer head 22 is movably arranged at the nozzle 14. When the nozzle tip operating end of the transfer head 22 extends out of the nozzle 14, it is convenient to correct the belt scratching operation.

[0030] An arc guide groove 15 is provided in the housing 1. The arc guide groove 15 includes a first arc guide groove and a second arc guide groove which are arranged opposite to each other. The first arc guide groove is provided on the first housing 11, and the second arc guide groove is provided on the second housing 12. The first housing 11 and the second housing 12 both include a bottom plate and a side plate enclosed by the periphery of the bottom plate. A side edge is provided on the bottom plate near the side plate. The first arc guide groove and the second arc guide groove for sliding the soft membrane 3 are formed between the side plate and the side edge. The structures and the setting positions of the first arc guide groove and the second arc guide groove are the same. The first arc guide groove and the second arc guide groove constitute the arc guide groove 15 of the housing 1.

[0031] The width of the arc guide groove 15 matches the thickness of the soft film 3 and the arc guide groove 15 can be movably extended to the position corresponding to the nozzle 14. The soft film 3 is made of a soft deformable material, preferably a PVC material. The soft film 3 is in the shape of a square strip, and the two ends along its width are movably placed in the first arc guide groove and the second arc guide groove respectively, that is, the soft film 3 is movably placed between the first arc guide groove and the second arc guide groove, so that the soft film 3 can slide in the arc guide groove 15 under the guidance of the arc guide groove 15. The first arc guide groove and the second arc guide groove arranged relatively can make the sliding of the soft film 3 smoother, so as to smoothly eject or close the nozzle. It should be noted that the structure, arc trajectory and setting position of the arc guide groove 15 can be adjusted according to the actual needs of the winding stationery, as long as the nozzle can be closed. For example, in a roll-up stationery using a common shell 1 such as a round or square shape, an arc-shaped guide groove 15 formed by two side edges is provided, and the setting of the arc-shaped guide groove 15 may not be affected by the side panels of the first shell 11 or the second shell 12 .

[0032] The soft film 3 has a free end 31 and a connection end 32 connected to the inner core sliding member 2. A connection member 23 is provided on one side of the inner core sliding member 2. The connection member 23 is fixed to the connection end 32 of the soft film 3 by bonding or other methods, so that when the nozzle is pushed or closed by the inner core sliding member 2, the free end 31 of the soft film 3 slides freely along the arc guide groove 15. Specifically, the nozzle 14 includes a first end 141 and a second end 142. The connection end 32 is provided on a side close to the first end 141, and the free end 31 can move back and forth between the first end 141 and the second end 142. When ejecting, the free end 31 slowly moves from the first end 141 to the second end 142 until the end of the free end 31 is set at the second end 142. At this time, the nozzle 14 is in a fully open state, and the transfer head 22 can be fully extended out of the nozzle 14; when closing, the free end 31 slowly moves from the second end 142 to the first end 141 until the end of the free end 31 is set at the first end 141. At this time, the nozzle 14 is in a fully closed state, and the transfer head 22 can be completely retracted into the housing 1. The correction tape is connected to the connecting end 32 of the soft film 3 through the input end, and the free end 31 is movably arranged between the first end 141 and the second end 142. The push button 4 drives the inner core slider 2 to move, thereby driving the connecting end 32 connected to the inner core slider 2 to move, so that the free end 31 moves back and forth between the first end 141 and the second end 142, and the opening and closing state of the nozzle is realized. The present invention does not need to set a plurality of grooves on the soft film, thereby enhancing the strength of the soft film. The present invention has the advantages of simple and convenient operation, high efficiency and labor saving, high recoverability and durability.

[0033] The inner core slide 2 has an input end and an output end, and the transfer head 22 is fixed to the output end. The output end is arranged corresponding to the nozzle 14, and the input end is transmission-connected with a control component that drives the inner core slide 2 to move along its length direction. The control component includes a push button 4 and an inner core rib 5 arranged on the inner core slide 2. The push button 4 includes a push button connection buckle 41 and a push button pressure rib 42. The push button 4 is integrally connected to the inner core rib 5 through the push button connection buckle 41 and the push button pressure rib 42. The push button 4 is convenient for manually pushing and closing the nozzle. The push button connection buckle 41 is provided with a limit block 411 at both ends along the width direction of the first shell 11 to prevent the push button 4 from detaching from the first shell 11, and the bottom plate of the first shell 11 is arranged between the push button 4 and the limit block 411.

[0034] The present invention further comprises an inner core snap button 24 disposed on the inner core sliding member 2 and a first fastener 111 and a second fastener 112 disposed on the first housing 11, wherein the first fastener 111 and the second fastener 112 are both disposed along the length direction of the first housing 11. It is worth noting that the inner core snap button 24 is made of an elastic plastic material, so that the inner core snap button 24 is easy to deform.

[0035] The first housing 11 is provided with a long strip-shaped slide groove 113 for the push button 4 to slide. The slide groove 113 is arranged along the length direction of the first housing 11. The width of the push button connection buckle 41 matches the width of the slide groove 113. The push button connection buckle 41 is relatively movable in the slide groove 113. Preferably, the first housing 11 is also provided with a step 114 for the push button 4 to be placed. The step 114 is arranged along the periphery of the slide groove 113. The push button 4 is arranged on the step 114. The width of the push button 4 matches the width of the step 114. The upper surface of the push button 4 is flush with the upper surface of the first housing 11. The push button 4 can be relatively movable on the step 114. The upper surface of the push button 4 is convexly provided with anti-skid convex particles and anti-skid convex patterns. The two ends of the upper surface of the push button 4 are in an arc shape for easy pushing. The arc matches the arc of the corresponding contact surface of the thumb of the human body. When in use, the thumb can be in closer contact with the push button 4, and the anti-skid convex edge and the anti-skid convex particles not only have an anti-skid effect but also have a massage effect, which can increase the comfort of the pushing operation and conform to the ergonomic design.

[0036] The first fastener 111 and the second fastener 112 are both arranged along the length direction of the first shell 11, and the first fastener 111 and the second fastener 112 are respectively and symmetrically arranged on both sides of the slide groove 113, the push button pressure rib 42 is movably arranged in the slide groove 113, and the inner core spring buckle 24 is movably connected with the push button pressure rib 42, the first fastener 111 and the second fastener 112.

[0037] The inner core snap button 24 is connected with the push button pressure rib 42, and the first inclined surface 61 is provided on the opposite side of the two; the first fastener 111 and the second fastener 112 both include a nozzle-shrinking fixed end 1111 and a nozzle-out fixed end 1112, and the inner core snap button 24 and the nozzle-shrinking fixed end 1111 of the first fastener 111 and the nozzle-shrinking fixed end 1111 of the second fastener 112 are matched with the second inclined surface 62 for facilitating the sliding of the inner core snap button 24; the inner core snap button 24 and the nozzle-out fixed end 1112 of the first fastener 111 and the nozzle-out fixed end 1112 of the second fastener 112 are matched with the right-angle surface 63 for preventing the inner core snap button 24 from sliding. It is worth noting that the first inclined surface 61 of the inner core snap button 24 and the second inclined surface 62 of the inner core snap button 24 in this embodiment are in the same plane, and for the convenience of description, they are not separated here.

[0038] The input end is the inner core rib 5, that is, the inner core rib 5 can push the inner core sliding part 2 to move by applying pressure through the push button 4, and a matching groove matching with the inner core rib 5 is provided on the push button 4, and the matching groove includes a first plane (that is, the bottom plate of the first shell 11) and a second plane vertically arranged on the first plane (that is, the side of the push button pressure rib 42 facing the push button connecting buckle 41) and a third plane (the side of the push button connecting buckle 41 facing the push button pressure rib 42), the first plane, the second plane and the third plane enclose a accommodating space for the inner core rib 5 to move, and the inner core rib 5 can be movably arranged in the accommodating space.

[0039] When the inner core rib 5 is located in the middle of the second plane and the third plane, the second inclined surface 62 of the inner core spring buckle 24 is in contact with the second inclined surface 62 of the nozzle fixed end 1111 of the first fastener 111 and the second inclined surface 62 of the nozzle fixed end 1111 of the second fastener 112 respectively, the first inclined surface 61 of the inner core spring buckle 24 is in contact with the first inclined surface 61 of the push button connecting buckle 41, and the inner core rib 5 is in a relaxed state. At this time, the retractable belt device of the present invention is completely located in the shell 1, that is, it is in the initial state.

[0040] For the convenience of description, the direction in which the push button 4 moves toward the nozzle 14 is defined as left, and the opposite direction is defined as right.

[0041] When the push button 4 slides to the left, that is, when the inner core rib 5 moves from the middle of the accommodating space to the second plane, the inner core rib 5 moves in the direction of the push button pressure rib 42 and contacts the second plane. At this time, the push button pressure rib 42 is separated from the inner core snap 24. If the push button 4 continues to slide to the left, a certain pressure is required to enable the push button pressure rib 42 to push the inner core rib 5 to move to the left; or when the push button 4 slides to the right, that is, when the inner core rib 5 moves from the middle of the accommodating space to the third plane, the push button pressure rib 42 needs a certain pressure to push the inner core snap 24. The second plane and the third plane are set to inform the user of the current state of use and as a pre-operation action for the retraction of the belt retracting device of the present invention, mainly to inform the user of the initial state of the belt retracting device when it is located in the housing 1.

[0042] When the push button 4 moves to the left, the inner core spring buckle 24, which cooperates with the nozzle fixed end 1111 of the first fastener 111 and the nozzle fixed end 1111 of the second fastener 112, both present a second inclined surface 62 for facilitating the sliding of the inner core spring buckle 24. Through the action of force and the elastic force of the inner core spring buckle 24, the inner core spring buckle 24 has a tendency to move leftward and downward, that is, the inner core spring buckle 24 slides from the nozzle fixed end 1111 of the first fastener 111 and the nozzle fixed end 1111 of the second fastener 112 to the lower surface of the first fastener 111 and the lower surface of the second fastener 112, and then slides to the nozzle fixed end 1112 of the first fastener 111 and the nozzle fixed end 1112 of the second fastener 112. The inner core spring buckle 24 is separated from the lower surface of the first fastener 111 and the lower surface of the second fastener 112, and the inner core spring buckle 24 is restored to its initial state through its own elastic restoring force. At this time, the right-angle surface 63 of the inner core spring buckle 24 abuts against the right-angle surface 63 of the nozzle fixed end 1112 of the first fastener 111 and the right-angle surface 63 of the nozzle fixed end 1112 of the second fastener 112. At this time, the present invention completes the nozzle pushing action and the belt stripping operation can be carried out smoothly.

[0043] When the push button 4 moves to the right, the inner core spring buckle 24 is connected with the push button pressure rib 42, and the first inclined surface 61 is provided on the opposite side of the two. The two first inclined surfaces 61 act on the inner core spring buckle 24 through the force and the elastic force of the inner core spring buckle 24, so that the inner core spring buckle 24 has a tendency to move rightward and downward, that is, the inner core spring buckle 24 slides from the nozzle fixed end 1112 of the first fastener 111 and the nozzle fixed end 1112 of the second fastener 112 to the lower surface of the first fastener 111 and the lower surface of the second fastener 112, and then slides to the nozzle fixed end 1111 of the first fastener 111 and the nozzle fixed end 1111 of the second fastener 112. The inner core spring buckle 24 is separated from the lower surface of the first fastener 111 and the lower surface of the second fastener 112, and the inner core spring buckle 24 is restored to its initial state through its own elastic restoring force. At this time, the second inclined surface 62 of the inner core spring buckle 24 abuts against the retracted nozzle fixed end 1111 of the first fastener 111 and the retracted nozzle fixed end 1111 of the second fastener 112. At this time, the present invention completes the nozzle closing action.

[0044] By adopting the above-mentioned design scheme, the beneficial effects of the present invention are: when closing the nozzle, the control component, the inner core slider 2 and the soft film 3 cooperate with each other, and the nozzle door and the nozzle push, as well as the nozzle door and the nozzle closing can be carried out smoothly and relatively fixed at the same time. It solves the problem in traditional technology that the transfer head 22 and the inner core slider 2 cannot bear the force of stripping, causing the transfer head 22 and the inner core slider 2 to slide back. Compared with the traditional nozzle push winding stationery that requires the help of pressing force, the entire operation process of the present invention is simple, convenient, efficient and labor-saving. The push button 4 can realize the functions of pushing forward and retracting without pressing up and down by applying forward and backward thrust. In addition, the structure of the present invention is simple and novel, and the elastic rib buckle is elastic, highly recoverable and durable. At the same time, the correction tape is connected to the connecting end 32 of the soft film 3 through the input end, and the free end 31 is movably arranged between the first end 141 and the second end 142. The push button 4 drives the inner core sliding member 2 to move, thereby driving the connecting end 32 connected to the inner core sliding member 2 to move, so that the free end 31 moves back and forth between the first end 141 and the second end 142, thereby realizing the opening and closing state of the nozzle.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
