Description

Technical Field

[0001] The invention relates to an outer covering device applied to a film applicator, in particular to a rotary film applicator which is easy to operate and can easily replace an internal film applicator. Background Art

[0002] Early film applicators (i.e., correction tapes) had a front application portion (such as the tongue plate and the tape) that was normally exposed, so it was inevitable that the film applicator would stick to surrounding objects when it was put away. There are many known devices that use a push-type linkage mechanism and a shell to accommodate and link the film applicator, so that when the film applicator is not in use, the application portion can be hidden in the shell, and when it is ready to use, the user can push the application portion out of the shell by pressing a button, and after use, release the button to retract the application portion into the shell. However, although this push-type device used in the film applicator can improve the problem of the application portion being exposed, when the button is squeezed (such as when stored in a pencil case) or collided, the application portion will still be pressed out, causing the tape to stick or even damage the tongue plate.

[0003] In addition, the conventional outer covering device used in the thin film applicator has a linkage mechanism that uses many and complex components, and the push-up or reset components often fail to firmly position the thin film applicator, and the internal parts will make a collision sound when shaking, causing trouble to the user; furthermore, in the conventional outer covering device, when the internal thin film applicator is replaced, it is inevitable that the linkage components will fall off, and the user often needs to carefully assemble the components, or replace some components at the same time, which is extremely inconvenient. Summary of the invention

[0004] The present invention provides a rotary thin film coating device, which aims to solve the shortcomings of the prior art, improve the deficiencies of the pressing mechanism in the storage environment, and provide a simple and stable linkage mode. When replacing the coating unit, there is no need to reassemble the components, and the operation is extremely convenient.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A rotary film coating device comprises a housing and a coating unit, wherein the housing has an internal space capable of accommodating the coating unit, and comprises a front housing and a rear housing capable of being relatively combined, a front opening is formed at the front end of the front housing, so that a coating portion protruding from the coating unit can extend out of the front opening; the characteristics are:

[0007] The rear housing is provided with a push-up member capable of abutting against the smearing unit from the front side, and a rotating member is provided at the rear side of the push-up member, and the rotating member can rotate to link the push-up member, so that the push-up member pushes the smearing unit forward;

[0008] The front housing is provided with a sheath at the front opening, and the sheath contains an elastic element for allowing the smearing unit to push against the elastic element at the other side relative to the ejecting member;

[0009] When the smearing unit moves forward to a forward position, the elastic element is in a compressed state and the smearing portion extends out of the front opening; and when the elastic element is released, it can push the smearing unit to move back to a rear position, and the smearing portion retracts into the front opening.

[0010] Further:

[0011] The sheath comprises a sleeve portion extending into the front opening, the elastic element is arranged around the inner edge of the sleeve portion, and the sleeve portion is provided with at least one inner flange to prevent the elastic element from detaching from the sleeve portion.

[0012] Further:

[0013] The sleeve portion is provided with at least one slide groove along the extension direction, and the application unit is provided with at least one abutting top portion corresponding to the slide groove, and the abutting top portion can move along the slide groove and abut the elastic element.

[0014] Further:

[0015] The ejection member is provided with at least one linkage protrusion on the side thereof, and the rotating member is extended to form an end edge which abuts against the linkage protrusion, so that the ejection member can be pushed by the end edge when the rotating member rotates.

[0016] Further:

[0017] The ejector is further provided with at least one limiting protrusion on the side thereof, and the rear housing is provided with at least one limiting groove in the front-rear direction corresponding to the limiting protrusion, so that the ejector can move forward and backward along with the limiting protrusion according to the direction of the limiting groove.

[0018] Further:

[0019] The end edge includes at least one concave edge positioning area and at least one flange positioning area. When the rotating member is at a first rotation angle, the concave edge positioning area is pressed against the linkage protrusion, and the smearing unit is located at the rear position. When the rotating member is at a second rotation angle, the flange positioning area is pressed against the linkage protrusion, and the smearing unit is located at the forward position.

[0020] Further:

[0021] The linkage protrusion is stacked on the limiting protrusion or the limiting protrusion is stacked on the linkage protrusion.

[0022] Further:

[0023] The rotating member is provided with a stopper on one side thereof, and the rear housing is provided with at least one protrusion for stopping the stopper.

[0024] Further:

[0025] The rear shell and the front shell are pivotally connected to each other at one side, and are detachably buckled to each other at the other side by a buckling portion and a buckled portion.

[0026] Further:

[0027] The angle difference between the first corner and the second corner is 90 degrees.

[0028] The present invention is beneficial in that:

[0029] The present invention adopts a rotating linkage mechanism design, so that when the whole is stored in a container such as a pencil case, the internal application unit will not be driven due to squeezing or collision. When in use, the positioning area provided by the rotating member allows the user to easily rotate the rotating member to position the application unit in a forward position with the front end extended. After use, the rotating member can be slightly rotated to position the application unit in a rear position with the front end retracted through the elastic force released by the elastic element. The operation is extremely convenient. Moreover, through the simple and stable structural design, when the internal application unit is replaced, the related linkage components no longer have the problem of falling off or reorganization, which also helps to improve the overall convenience of use.

DETAILED DESCRIPTION

[0042] In order to more clearly illustrate the technical solution of the present invention, the following will briefly introduce the drawings required for the description. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other embodiments can be obtained based on these drawings without creative work. In order to facilitate the understanding of the present invention, the present invention is described in more detail below in combination with the drawings and specific embodiments.

[0043] It should be noted that when an element is described as being "fixed to" another element, it may be directly on the other element, or one or more centered elements may exist therebetween. When an element is described as being "connected" to another element, it may be directly connected to the other element, or one or more centered elements may exist therebetween. The terms "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc., etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown:

[0045] It can be seen that the main structure of this embodiment is a shell 1, the interior of the shell 1 is hollow, forming an internal space that can accommodate an application unit 60, and the shell 1 is composed of a front shell 10 and a rear shell 20 relatively assembled; wherein the front shell 10 and the rear shell 20 are respectively provided with a pivot shaft 11 and a pivot hole 21 that can be pivotally connected to each other on one side of the joint position, and are respectively provided with a fastened portion 12 and a fastening portion 22 that can be fastened to each other on the other side. When the fastening portion 22 is separated from the fastened portion 12, the rear shell 20 can pivot relative to the front shell 10 (such as Fig. 9 As shown), the inner space of the housing 1 is exposed so as to place or replace the application unit 60.

[0046] The front shell 10 has a front opening 13 at the front end, so that an application portion 61 at the front end of the application unit 60 can extend out of the front opening 13 when in use. The front shell 10 is also provided with an anti-slip kit 14 near the front opening 13 to facilitate gripping and enhance comfort.

[0047] like Figure 3 As shown, the front shell 10 is sleeved with a sheath 30 at the position of the front opening 13. The sheath 30 is tubular and includes a sleeve portion 31 extending toward the inside of the front opening 13. An elastic element 32 is accommodated at the inner edge of the sleeve portion 31, and a plurality of inner flanges 311 are provided at the end where the sleeve portion 31 extends, so as to ensure that the elastic element 32 can be retained in the sleeve portion 31 and will not fall out; one end of the elastic element 32 is pressed against the inner side of the sheath 30, and the other end is used to form abutment with the application unit 60. In this embodiment, the sleeve portion 31 is provided with two slide grooves 312 extending along the extension direction of the sleeve portion 31 at a position staggered from the inner flange 311, and the application unit 60 is provided with two abutment tops 62 at relative positions, so that the abutment tops 62 can move along the slide grooves 312 and abut against the elastic element 32 on the inner side of the sleeve portion 31.

[0048] like Figure 2 , Figure 4 and Figure 5 As shown:

[0049] A push member 40 is disposed in the rear housing 20 , and a rotating member 50 is assembled at the rear side of the push member 40 . The rotating member 50 can rotate and link the push member 40 , so that the push member 40 pushes the application unit 60 forward. Among them, the front end of the push member 40 is used to resist the smear unit 60, and a limiting convex portion 42 is convexly provided on the two opposite sides, and a linkage convex portion 41 is convexly provided on each of the limiting convex portions 42; the rear shell 20 is respectively provided with a limiting groove 23 corresponding to each of the limiting convex portions 42, and each of the limiting grooves 23 extends in the front-to-back direction for each of the limiting convex portions 42 to move forward and backward therein, so that the moving direction of the push member 40 is limited by the direction of the limiting groove 23 along with the limiting convex portion 42; and an end edge 51 of the rotating member 50 extending toward the push member 40 is convex and concave, and the extended end edge 51 resists the linkage convex portion 41, so that when the rotating member 50 rotates, the linkage convex portion 41 of the push member 40 can be driven by the convex and concave end edge 51.

[0050] The convex and concave shape of the end edge 51 may form a concave edge positioning area 511 and a convex edge positioning area 512 with corresponding positions and numbers according to the linkage protrusion 41. When the rotating member 50 is at a first rotation angle, the concave edge positioning area 511 abuts against the linkage protrusion 41, and when the rotating member 50 is at a second rotation angle, the convex edge positioning area 512 abuts against the linkage protrusion 41. In this embodiment, the angle difference between the first rotation angle and the second rotation angle is 90 degrees to provide the best smoothness, so as to facilitate the user's rotation operation. In other embodiments, the first rotation angle and the second rotation angle may also be provided with an angle difference different from that of this embodiment. Furthermore, the rotating member 50 may be provided with a stopper 52 on the outer side, and the rear housing 20 may be provided with a convex block 24 at an appropriate position for stopping the stopper 52, so as to facilitate the user to position the rotating member 50 at an appropriate rotation angle when operating the rotating member 50. In this embodiment, the convex block 24 is provided at a position convenient for positioning at the second rotation angle.

[0051] In the present embodiment, each of the linkage protrusions 41 is stacked on each of the limiting protrusions 42, and the rear housing 20 includes an inner layer structure between the ejecting member 40 and the extended end edge 51, so that each of the limiting grooves 23 can be opened in the inner layer structure to facilitate the respective movements of the rotating member 50 and the ejecting member 40; and in other feasible embodiments, the corresponding relationship between the linkage protrusions 41 and the limiting protrusions 42 is not limited thereto, and the limiting protrusions 42 can be stacked on the linkage protrusions 41, and the rear housing 2 can open the limiting grooves 23 on the outer side of the extended end edge 51, or the limiting protrusions 42 and the linkage protrusions 41 are respectively arranged at positions of different depths to achieve the effects of rotation linkage and limiting the moving direction.

[0052] like Figure 4 , Figure 6 As shown:

[0053] When not in use, the elastic element 32 is in a released state, pressing against the smear unit 60 to provide an elastic force to move it backward, so that the smear unit 60 is kept in a rear position, and the push-up member 40, due to the elastic force, allows the linkage protrusion 41 to push the end edge 51 of the rotating member 50 and position it in the concave edge positioning area 511, so that the rotating member 50 is kept at the first rotation angle; and when it is to be used, such as Figure 5 and Figure 7 As shown, the user can operate the rotating member 50 to rotate toward the second corner. At this time, the end edge 51 of the rotating member 50 can push the ejection member 40 until the rotating member 50 rotates to the second corner, and the flange positioning area 512 abuts against and positions the linkage protrusion 41, and the ejection member 40 can also push the application unit 60 forward to a forward position, so that the application portion 61 of the application unit 60 extends out of the front opening 13 (such as Figure 8 ), and compress the elastic element 32; and after use, the user only needs to slightly rotate the rotating member 50 to disengage it from the second corner position, so that the linkage protrusion 41 can be disengaged from the positioning state of the flange positioning area 512, and the elastic force of the elastic element 32 is released to allow the application unit 60 to move back to the rear position (i.e., return to the position shown in FIG. Figure 6 ), at which time the applying portion 61 is retracted into the front opening 13.

[0054] Another example Fig. 9As shown, when the material strip of the application unit 60 is used up, the user can press the snap-fitting portion 22 of the rear shell 20 to separate it from the snap-fitting portion 12 of the front shell 10, and can easily operate the rear shell 20 to pivot relative to the front shell 10 to expose the internal space for replacing a new application unit 60, and the sheath 30, elastic element 32, ejector 40 and rotating member 50, etc., are all firmly maintained in the predetermined position and will not be offset or detached due to the replacement process, so that the user's replacement operation can be extremely smooth and convenient.

[0055] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the present invention.
