Detailed implementation mode

[0031] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 to 7

[0033] For the convenience of narration, it is defined that the orientation where the head 11 (which will be introduced in detail below) of the correction tape is set is up, and the orientation where the nozzle 2 (which will be introduced in detail below) is set is down.

[0034] A correction tape with a refill installation mechanism includes a pen-shaped housing 1, an output device arranged in the housing 1, a nozzle 2 integrally or detachably connected to the output device, and a pressing structure for controlling the output device to drive the nozzle 2 to extend / retract from the housing 1. The structures and working principles of the nozzle 2 and the correction tape output device in this embodiment adopt the structures and working principles of the nozzles and output devices of conventional pen-shaped correction tapes in the industry, and will not be repeated here.

[0035] The output device includes a tape feeding wheel, a tape winding wheel, and a refill board 3. The housing 1 includes a head 11 and a rod portion 12 that both form cavities. The head 11 includes a first head 111 and a second head 112 that are snap-connected to each other. The second head 112 and the refill board 3 are fixedly connected integrally or separately. The first head 111 and the second head 112 are snapped together to form a first cavity 71 for placing the tape feeding wheel and the tape winding wheel. The rod portion 12 includes a first rod portion 121 and a second rod portion 122 that are snap-connected to each other. The first rod portion 121 and the second rod portion 122 are snapped together to form a second cavity 72 for placing the refill board 3, and an outlet 13 for the nozzle 2 to extend out of the housing 1 or retract into the housing 1 is provided at one end away from the head 11. The refill board 3 can be reciprocally moved in the direction of the outlet 13 by pressing the head 11, thereby realizing the extension or retraction of the nozzle 2 out of or into the housing 1.

[0036] Furthermore, the first head 111 and the second head 112 form the head 11 that is a pressing part, and the shape of the head 11 can be set into various shapes of the head 11, such as a cat's paw shape, etc.; in addition, the length of the refill board 3 can also be set according to actual situations, and it has strong compatibility with meter requirements.

[0037] This embodiment further includes a control member 4. The control member 4 is a columnar body with openings at the top and bottom, and the inner cavity of the control member 4 is a third cavity 73 for the refill board 3 to pass through. The lower end portion of the control member 4 is sleeved in the second cavity. The upper end portion of the refill board 3 is connected to the second head 112, and the lower end portion passes through the third cavity 73 and is partially arranged in the second cavity 72. A locking device for detachably connecting the refill board 3 to the control member 4 is provided between the control member 4 and the refill board 3, thereby realizing the connection between the head 11 and the rod portion 12.

[0038] Furthermore, a groove 41 is provided on the side wall of the control member 4 and a spring piece 42 with one end connected to the groove 41. The other end of the spring piece 42 is provided with a limiting hook claw 421. A limiting groove 31 adapted to the limiting hook claw 421 is provided on the outer side wall of the refill board 3. The limiting hook claw 421 is arranged in the limiting groove 31 to complete the locking, that is, the limiting groove 31 and the limiting hook claw 421 constitute a locking mechanism. Specifically, the spring piece 42 is a plastic part, and the plastic has micro-elasticity, and the groove 41 can provide a deformation space for the spring piece 42.

[0039] Further, inclined surfaces facilitating the sliding of the limiting hook claw 421 are provided on the lower end surfaces of the limiting groove 31 and the limiting hook claw 421, and limiting surfaces restricting the sliding of the limiting hook claw 421 are provided on the upper end surfaces of the limiting groove 31 and the limiting hook claw 421. The control member 4 is sleeved outside the refill plate 3. By using the elastic force generated by the deformation of the elastic piece 42, the limiting hook claw 421 slides upward on the outer side wall (excluding the limiting groove 31) of the refill plate 3 and into the limiting groove 31. The opposite inclined surfaces of the two slide relative to each other and are assembled, which is convenient for installation. When assembled, the opposite limiting surfaces of the two can restrict the limiting hook claw 421 from sliding upward continuously, thereby completing the connection between the refill plate 3 and the control member 4, that is, the connection between the head 11 and the rod portion 12. Compared with the traditional pen-shaped correction tape in this embodiment, when disassembling the refill plate 3 and the control member 4, there is no need to disassemble other components, avoiding the problem that the main function cannot be used due to the loss of parts. At the same time, the replacement steps are optimized to improve the replacement efficiency.

[0040] Preferably, an elastic body for promoting the reset of the control member 4 after the pressing portion (which will be introduced in detail below) is pressed is provided between the upper end portion of the rod portion 12 and the upper end portion of the control member 4. The elastic body can be a spring 6, a tension spring, a torsion spring, elastic plastic, etc., and preferably a spring 6. This spring 6 is tightly sleeved on the control member 4 along the length direction of the control member 4, and the upper end of this spring 6 abuts against the control member 4, and the lower end of the spring 6 abuts against the rod portion 12. Specifically, a limiting boss 43 for the upper end portion of the spring 6 to abut against is provided on the upper end portion of the control member 4, the outer diameter of the limiting boss 43 is larger than the inner diameter of the second cavity 72, a limiting convex ring 123 for connecting the lower end portion of the spring 6 is provided on the upper end portion of the rod portion 12, the lower end portion of the spring 6 is connected to the limiting convex ring 123, and the upper and lower ends of the spring 6 are respectively connected through the limiting boss 43 and the limiting convex ring 123. When the nozzle 2 retracts into the housing 1, the spring 6 is not pressed. When pressing the refill plate 3 downward, the spring 6 moves downward and drives the control member 4 to move downward, and the locking mechanism composed of the limiting groove 31 and the limiting hook claw 421 locks in the second cavity 72, realizing the nozzle 2 extending out of the housing 1.

[0041] Further, the pressing structure includes a pressing portion (the head 11 in this embodiment) and a rotating member 51 rotatably connected to the control member 4 and having a positioning function. A sliding track 52 for cooperating with the rotating member 51 to rotate is provided on the inner side wall of the rod portion 12 (the second rod portion 122) relative to the rotating member 51. Specifically, the first rod portion 121 and the second rod portion 122 can be two identical structures connected to each other, or the upper end portion of the first rod portion 121 with an open upper and lower shape is provided with a groove 123 adapted to the outer contour of the second rod portion 122, the second rod portion 122 is arranged on the groove 123, and the sliding track 52 is arranged on the side of the second rod portion 122 facing the second cavity 72.

[0042] Further, a through hole 44 adapted to the rotating member 51 is provided on the control member 4, and a rotating block 53 is provided on one side of the rotating member 51 facing the through hole 44. The rotating block 53 is rotatably provided in the through hole 44.

[0043] Further, the rotating member 51 is slidably provided in the sliding track 52. The sliding track 52 has a first positioning point for the rotating member 51 to move to retract the nozzle 2 into the outlet 13 and a second positioning point for the nozzle 2 to move to extend the nozzle 2 out of the outlet 13. The first positioning point is located above the second positioning point. When the rotating member 51 is stuck at the second positioning point, the sliding track 52 limits the rotating member 51 to overcome the elastic restoring force of the spring 6, so that the nozzle 2 can stably extend out of the outlet 13, thereby avoiding the situation that the nozzle 2 falls into the housing 1 when it is at the outlet 13. It should be noted that in this embodiment, the refill plate 3 is connected to the head 11. The refill plate 3 serves as the main output function of the correction tape, and the refill plate 3 is also used as the pressing part to coordinate the whole machine. Compared with the old structure, it avoids the problem that the main function cannot be used due to the loss of parts, saves accessories, reduces costs, and extends the service life.

[0044] Preferably, grooves are respectively formed at both ends of the rotating member. The grooves are V-shaped grooves, and their cross-sections are triangular. The rotating member 51 has a first side surface 511, a second side surface 512, a third side surface 513, a fourth side surface 514, a fifth side surface 515 and a sixth side surface 516. The first side surface 511 and the second side surface 512 are respectively located on both sides of one of the grooves, the third side surface 513 and the fourth side surface 514 are respectively located on both sides of the other groove, and the fifth side surface 515 and the sixth side surface 516 connect both sides of the two grooves. In this embodiment, in addition to being triangular, the cross-section of the groove can also be semi-circular, etc., and the shapes of the grooves at both ends of the rotating member 51 can be the same or different. In addition, in addition to forming grooves, the rotating member 51 can also be provided with protrusions, and their functions are the same as those of the grooves, which will not be described in detail here.

[0045] The sliding track 52 includes a communicating reduced-diameter track and a guiding track. The diameter of the reduced-diameter track is equivalent to the width of the rotating member 51 (the distance between the fifth side surface 515 and the sixth side surface 516), and the diameter of the guiding track is larger than the longest width of the rotating member 51 (the diagonal distance between the fifth side surface 515 and the sixth side surface 516), so that the rotating member 51 can only move but not rotate in the reduced-diameter track and move and rotate in the guiding track.

[0046] The guiding track includes a first contact surface 521, a second contact surface 522, a third contact surface 523 and a fourth contact surface 524. The reduced-diameter track includes a fifth contact surface 525 and a sixth contact surface 526, wherein the included angle between the first contact surface 521 and the second contact surface 522 is the same as the included angle between the first side surface 511 and the second side surface 512.

[0047] The state where the nozzle 2 extends: After the first downward press on the pressing part and then releasing it, the spring 6 is deformed by the press and enters the working state. The control member 4 moves downward against the deformation of the spring 6. When the rotating member 51 moves downward from the reduced-diameter track to the bottom end of the sliding track 52, since the axis of the rotating block 53 remains unchanged, the rotation of the rotating member 51 is achieved through the parallelism and contact between the first side surface 511 and the first contact surface 521, and between the second side surface 512 and the second contact surface 522 (i.e., the movement track from a to b). At this time, under the elastic restoring force of the spring 6, the rotating block 53 has an upward elastic force, causing the rotating member 51 to continue moving upward. When the third side surface 513 and the third contact surface 523 are parallel and in contact, the connection point between the fourth side surface 514 and the sixth side surface 516 abuts against the fifth contact surface 525, and the connection point between the second side surface 512 and the sixth side surface 516 abuts against the fourth contact surface 524. At this time, the rotating block 51 is clamped at the connection of the reduced-diameter track and the guiding track (i.e., the second positioning point), achieving the positioning of the rotating member 51 (i.e., the movement track from b to c). At this time, the nozzle 2 extends out of the outlet 13.

[0048] The state where the nozzle 2 retracts: When pressing the pressing part downward for the second time, the spring 6 is deformed by the press and enters the working state. The control member 4 moves downward against the deformation of the spring 6. When the rotating member 51 moves downward from the second positioning point to the bottom end of the sliding track 52, since the axis of the rotating block 53 remains unchanged, the rotation of the rotating member 51 is achieved through the parallelism and contact between the fifth side surface 515 and the second contact surface 522 (i.e., the movement track from c to d). At this time, under the elastic restoring force of the spring 6, the rotating block 53 has an upward elastic force, causing the rotating member 51 to continue moving upward. The connection point between the fourth side surface 514 and the sixth side surface 516 contacts the third contact surface 523 and continues to rotate until the sixth side surface 516 and the fifth contact surface 525 are parallel and in contact. At this time, the rotating block 51 is at the connection of the reduced-diameter track and the guiding track (i.e., the movement track from d to e). The rotating block 51 continues to move upward under the elastic force of the spring 6 in the reduced-diameter track to the top end of the sliding track 52 (i.e., the first positioning point), achieving the positioning of the rotating member 51 (i.e., the movement track from e to a). At this time, the nozzle 2 retracts into the outlet 13.

[0049] Preferably, the first side surface 511, the second side surface 512, the third side surface 513, the fourth side surface 514, the first contact surface 521, the second contact surface 522, the third contact surface 523, and the fourth contact surface 524 are all guiding inclined surfaces or guiding curved surfaces.

[0050] By adopting the foregoing design solution, the beneficial effects of the utility model are as follows: By connecting the head to the refill board, the refill board to the control member, and the control member to the rod portion, and at the same time, the refill board serves as the main output function of the correction tape, and the refill board or the head is also used as a button to coordinate the whole machine. Compared with the old structure, it avoids the problem that the main function cannot be used due to the loss of parts, saves accessories, reduces costs, and improves the service life.

[0051] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
