DETAILED DESCRIPTION

[0037] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are for example only, and those skilled in the art may think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0038] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0039] like Figure 1 , 2 As shown in , 3, a refill type telescopic correction tape is disclosed, comprising a refill 3 and a separable upper cover 1 and lower cover 2. The upper cover 1 and lower cover 2 are opened to replace the refill 3. After the upper cover 1 and the lower cover 2 are relatively covered, there is an opening at the front end, and the correction head 8 of the telescopic assembly 4 can extend from the opening. This example shows that the upper cover 1 is rotated to open / close relative to the lower cover 2, and other structures can also be used, such as the upper cover 1 is longitudinally opened / closed relative to the lower cover 2 as a whole. Any opening / closing structure applicable to the present disclosure can be applied to the present disclosure.

[0040] In this disclosure, Figure 2 , 3 As shown, a telescopic component 4 is provided on the upper cover 1 or the lower cover 2, and the telescopic component 4 opens / closes together with the upper cover 1 or the lower cover 2. Regardless of whether it is provided on the upper cover 1 or the lower cover 2, the structure is the same. In this example, the telescopic component 4 is provided on the upper cover 1 as an example in the direction shown in the figure.

[0041] like Figure 4 , 5, 7, 8, the telescopic assembly 4 includes a mounting seat 5, a push piece 6, a take-up gear 7, a correction head 8, a waste gear 9, a new belt gear 10, a first rotating shaft 11, and a second rotating shaft 12. The push piece 6 is connected to the correction head 8 to drive the correction head 8 to extend and retract. The push piece 6 and the correction head 8 can be integrally formed by injection molding, or two parts can be connected together. The mounting seat 5 is connected to the cover to form a accommodating interval. The push piece 6 is arranged in the accommodating interval. The take-up gear 7, the waste gear 9, and the new belt gear 10 can be rotatably connected to the mounting seat. The mounting seat 5 is provided with a take-up gear 7 passing through the mounting seat 5. The take-up gear 7 is divided into an upper part and a lower part by the mounting seat 5, and the waste belt gear 9 and the new belt gear 10 are both located on the same side as the lower part. The lower part meshes with the waste belt gear 9 for transmission and / or the lower part meshes with the new belt gear 10 for transmission. The upper part is connected to the push piece 6 in a one-way transmission when being retracted. The push piece 6 is used to drive the take-up gear 7 to rotate via the upper part when being retracted. The rotation of the take-up gear 7 drives the waste belt gear 9 and / or the new belt gear 10 to rotate.

[0042] The new belt gear 10 is connected to the first shaft 11 to drive the first shaft 11 to rotate, and the waste belt gear 9 is connected to the second shaft 12 to drive the second shaft 12 to rotate. The replacement core 3 includes a support and a new belt wheel 13 and a waste belt wheel 14 rotatably connected to the support. When the replacement core 3 is installed between the two covers, the first shaft 11 and the first hole 36 of the new belt wheel 13 are inserted and matched for transmission connection, and the second shaft 12 and the second hole 37 of the waste belt wheel 14 are inserted and matched for transmission connection. When the two covers are opened, the first shaft 11 and the new belt wheel 13 are separated from each other, and the second shaft 12 and the waste belt wheel 14 are separated from each other, and the replacement core 3 can be taken out and replaced.

[0043] In this way, the film tape can be rolled up, and when the push piece 6 is pushed outward, the take-up gear 7 will not be driven by the push piece 6 due to the one-way transmission, and the film tape is released from the new pulley 13 and / or the waste pulley 14 under the push of the correction head 8. The release must require the new pulley 13 and / or the waste pulley 14 to rotate. At this time, it can be set that the new pulley 13 can slip relative to the first rotating shaft 11 and / or the waste pulley 14 can slip relative to the second rotating shaft 12. The slipping structure can adopt the existing technology and will not be repeated here. Based on and / or, three cases have been given as examples, and of course other structures can also be used. Any structure that can achieve the release of the film tape can be applied to the present disclosure.

[0044] The main function of the support is to install the new pulley 13 and the waste pulley 14. The support can be an upper support plate 34, a lower support plate 35, or both. As mentioned above, there are three possible situations.

[0045] In this case, Figure 2 , 3 As shown in Figures 6 and 7, the new belt wheel 13 and the waste belt wheel 14 are rotatably connected between the upper support plate 34 and the lower support plate 35.

[0046] In some embodiments, Figure 1 , 2 As shown in FIGS. 3 and 4, the push piece 6 is designed in an L shape, and the L shape includes an axial portion 15 and a longitudinal portion 16. The axial portion 15 can be telescopically matched with the accommodation interval, and the longitudinal portion 16 is used to connect the correction head 8. The longitudinal portion 16 and the portion formed by the correction head 8 are distributed front and back between the main body of the refill 3. After such a design, it is beneficial to reduce the thickness dimension, because the aforementioned improvement allows the longitudinal portion 16 and the portion formed by the correction head 8 to be distributed front and back between the main body of the refill 3, so that they are distributed in the length direction, so that the thickness dimension does not need to be overlapped to increase the thickness dimension, which is beneficial to reduce the thickness dimension.

[0047] Furthermore, the refill 3 is provided with a longitudinally arranged matching groove 17 at the front end. When the two covers are closed, the longitudinal portion 16 together with the correction head 8 are inserted into the matching groove 17. In this way, because the matching groove 17 accommodates the longitudinal portion 16 and the correction head 8, the portion constituted by the longitudinal portion 16 and the correction head 8 is distributed front and back between the main body of the refill 3, which is conducive to reducing the length direction dimension.

[0048] In some embodiments, Figure 3 As shown, when one of the two covers is provided with the telescopic assembly 4, the other of the two covers is provided with the accommodating cavity 18, and the accommodating cavity 18 is sleeved and installed with the refill 3. In this example, the lower cover 2 is provided with the accommodating cavity 18. This is more convenient for users to use, and users can place the refill 3 with a little attention, and then can safely close the two covers to achieve the purpose of replacing the refill 3.

[0049] In some embodiments, Figure 4 , 7 8, it also includes an intermediate transmission gear 19, which is provided with a first tooth portion 20 and a second tooth portion 21 in sequence along the longitudinal direction, and the push piece 6 is provided with a rack segment 22, a matching interval is formed between the first tooth portion 20 and the mounting seat 5, the rack segment 22 is inserted and matched in the matching interval and unidirectionally meshes with the second tooth portion 21, and the second tooth portion 21 meshes with the tooth portion of the upper part of the take-up gear 7. After such a design, the layout can be further optimized through the intermediate transmission gear 19, which is conducive to simplifying the shape design and assembly of the push piece 6, so that the push piece 6 is mainly designed to focus on the requirements of axial movement.

[0050] Further, such as Figure 4 , 7As shown in FIG. 8 , the push piece 6 is provided with an elastically swingable cantilever 23 extending toward the mating interval, and a rack segment 22 is provided at the end of the cantilever 23. In this way, it is not only conducive to further simplifying the structure, but also conducive to realizing the function of one-way transmission, that is, the push piece 6 can be integrally formed with the cantilever 23 by injection molding, and the elasticity of the plastic is used to make the rack segment 22 elastically and one-way mesh with the teeth of the upper part. When retracted, the rack segment 22 can push the upper part to rotate, and when extended, the push piece 6 can be pushed outward smoothly by elasticity without driving the upper part to rotate. Of course, there are other one-way transmission structures, and all applicable ones can be used in the present disclosure.

[0051] Further, such as Figure 5 , 9 As shown, a third rotating shaft 24 and a fourth rotating shaft 25 are provided on the top wall of the upper cover 1. When the mounting base 5 is connected to the upper cover 1, the take-up gear 7 is rotationally connected to the third rotating shaft 24, and the intermediate transmission gear 19 is rotationally connected to the fourth rotating shaft 25. This makes it easy to connect the take-up gear 7 and the intermediate transmission gear 19, which is conducive to easy assembly.

[0052] In some embodiments, Figure 4 , 9 As shown in Figures 10 and 11, the cover on which the telescopic assembly 4 is provided is provided with a guide hole 26, and the push piece 6 is longitudinally connected with a push portion 27, and the push portion 27 is connected with the push piece 6 to form a clamping groove 28, and the guide hole 26 is provided with a guide portion 29 that cooperates with the clamping groove 28. In this way, on the one hand, the push portion 27 is constrained and guided, and on the other hand, the guiding cooperation setting of the clamping groove 28 and the guide portion 29 facilitates the connection of the push piece 6 to the upper cover 1, thereby facilitating assembly. In this example, an undercut 38 is provided for snap connection to facilitate the connection of the push portion 27 and the push piece 6 along the longitudinal direction, facilitate assembly, and also facilitate the formation of the clamping groove 28 and the realization of the guiding cooperation setting with the guide portion 29.

[0053] Furthermore, the push portion 27, the cover, and the push piece 6 are longitudinally connected to form a first assembly, which is conducive to convenient assembly.

[0054] Further, such as Figure 5 , 12 As shown in , 13, 14, and 15, the side surface of the mounting seat 5 located on one side of the refill 3 is provided with a first connecting shaft 30 and a second connecting shaft 31. The first connecting shaft 30 limits the new belt gear 10 longitudinally on the mounting seat 5, and the second connecting shaft 31 limits the waste belt gear 9 longitudinally on the mounting seat 5. The mounting seat 5, the new belt gear 10, and the waste belt gear 9 are connected to form a second component, and the first component and the second component are longitudinally connected to form a third component. In this way, it is more convenient to assemble. In this example, the heads of the first connecting shaft 30 and the second connecting shaft 31 are both set to be inverted cones that can be elastically closed together to achieve insertion and longitudinal limitation after insertion.

[0055] Further, such as Fig. 9 , 12 As shown in FIGS. 15 and 16, a third rotating shaft 24 is provided on the top wall of the cover, and a barb 32 is provided on the third rotating shaft 24. The mounting seat 5 is provided with a through hole 33 for the belt-receiving gear 7 to pass through to form an upper portion. The through hole 33 is arranged opposite to the third rotating shaft 24. After the first assembly and the second assembly are longitudinally connected, the belt-receiving gear 7 is inserted from the through hole 33 and is rotatably connected to the third rotating shaft 24, and the barb 32 forms a longitudinal limit for the belt-receiving gear 7. In this way, it is more convenient to assemble.

[0056] So, from Figures 13 to 16 , the telescopic component 4 is assembled on the upper cover 1.

[0057] In some embodiments, Fig.13 As shown, it also includes an intermediate transmission gear 19, which is provided with a first tooth portion 20 and a second tooth portion 21 in sequence along the longitudinal direction, and a push piece 6 is provided with a rack segment 22. A fourth rotating shaft 25 is provided on the top wall of the upper cover 1. The intermediate transmission gear 19 is mounted on the fourth rotating shaft 25, and the push portion 27, the upper cover 1, and the push piece 6 are longitudinally connected to form a first component. In the first component, the rack segment 22 longitudinally clamps the first tooth portion 20 between the rack segment 22 and the top wall of the upper cover 1.

[0058] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0059] The above description is only an illustrative embodiment of the present invention, so any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
