Description

Technical Field

[0001] The utility model relates to the field of stationery, in particular to a novel retractable eraser. Background Art

[0002] An eraser is a commonly used stationery item for erasing handwriting. Generally, erasers are sold with a paper outer package, while some are without it and have information printed directly on the eraser. For an eraser without outer package protection, after being used for a period of time, its surface will get dirty. If the eraser is large in size, without protection, it is prone to cracks or even breakage during use. An eraser with a paper package can reduce the dirt on the eraser at the initial stage of use and can support the main body of the eraser, reducing the occurrence of cracks or even breakage.

[0003] The use of the paper package has a time limit. When the initially exposed part of the paper package of the eraser is used up, it is necessary to push the eraser to make it expose at the opening of the paper package again. At this time, for the sake of convenience, most people will choose to remove the outer package of the eraser. Otherwise, when using the eraser, the eraser will shrink into the paper package, which is very inconvenient. Due to the particularity of the paper package, generally, erasers using paper packages are regular cubes or cuboids, and more special-shaped erasers do not use outer packages.

[0004] Regarding the above related technologies, the inventor believes that there is an urgent need for an outer package that can be used for special-shaped erasers and can freely push the eraser and lock it after it is pushed out of the outer package without affecting normal use. Summary of the Utility Model

[0005] In order to solve the problem that it is difficult for special-shaped erasers to have a suitable outer package and can freely push the eraser and lock it after it is pushed out of the outer package without affecting normal use, this application provides a novel retractable eraser.

[0006] The novel retractable eraser provided by this application adopts the following technical solution:

[0007] A novel retractable eraser includes an eraser body and its outer package. The eraser body is special-shaped. The outer package includes a shell with at least one side open. The special-shaped eraser body is installed in the shell, and the minimum size of the shell is greater than or equal to the maximum size of the eraser body in the direction of its being pushed out of the shell;

[0031] The following will further describe the present application in detail Figures 1-5 in conjunction with the appended

[0032] The embodiment of the present application discloses a new type of retractable rubber. Referring to Figure 1 , a new type of retractable rubber includes a rubber body 1 and its outer package 2. The rubber body 1 is of a special shape. In this embodiment, the shape of the rubber body 1 is a sector ring. To facilitate the clamping of the rubber body 1, the sector ring is an irregular sector ring, that is, one end of the sector ring extending into the outer package 2 is cut flat.

[0033] Referring toFigures 1-2 The outer package 2 includes a shell 21 with at least one side open, the special-shaped rubber body 1 is installed in the shell 21, and the minimum size of the shell 21 is greater than or equal to the maximum size of the rubber body 1 in the direction in which it is pushed out of the shell 21. When the special-shaped rubber body 1 is a fan ring, the width of the shell 21 is greater than or equal to the width of the fan ring, and the thickness of the shell 21 is greater than or equal to the thickness of the fan ring, so that the shell 21 is wrapped around the outside of the fan ring.

[0034] Reference Figures 2-3 A guide groove 22 is provided on the housing 21 in the direction in which the rubber body 1 is pushed out of the housing 21. A locking member 3 is slidably connected in the guide groove 22. One end of the locking member 3 extends into the housing 21 and is provided with a clamping member 4. The clamping member 4 clamps the end of the rubber body 1 extending into the housing 21. Pressing the locking member 3 causes the locking portion 32 thereof to be out of contact with the guide groove 22, and the locking member 3 can be pushed to slide in the guide groove 22, thereby controlling the rubber body 1 to extend out of the outer package 2.

[0035] Reference Figures 3-4 The locking member 3 includes a pressing plate 31, a locking portion 32 and an elastic plate 33. The locking portion 32 is located between the pressing plate 31 and the elastic plate 33 and connects the two. The pressing plate 31 is located above the guide groove 22, the locking portion 32 is located at the guide groove 22, and one end of the elastic plate 33 away from the locking portion 32 is fixed to the clamping member 4. The locking portion 32 includes teeth 34. The guide groove 22 is provided with continuous teeth 34 grooves 23 on one side opposite to the guide groove 22 along its length direction. The teeth 34 are flush with the guide groove 22 and embedded in the teeth 34 grooves 23 to achieve the purpose of locking.

[0036] Reference Figures 3-4 The elastic plate 33 is bent and formed with an opening, one end of the opening is installed with the locking portion 32, and the other end is fixed to the clamping member 4. The elastic plate 33 is pressed by the pressing plate 31, and the opening of the elastic plate 33 is gradually closed, so that the tooth 34 is separated from the tooth 34 groove 23. The elastic plate 33 is one of a U-shaped plate, a V-shaped plate, an S-shaped plate, a C-shaped plate, an N-shaped plate, and an M-shaped plate. In this embodiment, a U-shaped plate is used, and the elastic plate 33 is made of PP material with good elasticity.

[0037] Reference Figures 3-5, the clamping member 4 includes two clamping end plates 41 and a connecting plate 42 connecting the two clamping end plates 41. On the opposite sides of the clamping end plates 41, there are friction lines 45 for increasing friction. The friction lines 45 are one of straight protrusions, convex points, and wavy protrusions. In this embodiment, three straight protrusions are used as the friction lines 45. The clamping end plates 41 are tightly fastened to both sides of one end of the rubber body 1 extending into the housing 21. One end of the elastic plate 33 away from the locking portion 32 is fixed to the connecting plate 42. There is a convex block 43 on the connecting plate 42, and a groove 44 is provided on the inner wall of the housing 21. The groove 44 is arranged along the length direction of the housing 21. The convex block 43 is located in the groove 44 and is slidably arranged along the length direction of the groove 44, making the process of pushing the rubber more stable.

[0038] To reserve space for the clamping end plates 41, the width of the housing 21 is greater than the width of the sector ring in this embodiment. To improve the clamping stability of the rubber body 1, one end of the sector ring extending into the outer package 2 is closely attached to one side of the connecting plate 42.

[0039] The implementation principle of a novel retractable rubber in an embodiment of this application is as follows: In the initial situation, one end of the rubber body 1 extends out of the housing 21. When this part of the rubber is used until it is inconvenient to continue using, press the pressing plate 31 so that the end of the U-shaped plate provided with the locking portion 32 displaces towards the end fixed to the connecting plate 42, so that the tooth 34 disengages from the tooth 34 groove 23. The pressing plate 31 can be slid along the length direction of the guiding groove 22 to extend out a part of the rubber body 1 again. The unused part of the rubber body 1 is always protected by the housing 21 and will not get dirty. Since the rubber body 1 extending out of the housing 21 is controllable, it is also difficult to cause the rubber body 1 to break. Release the pressing plate 31, and the elastic plate 33 resets, and the tooth 34 is inserted into the tooth 34 groove 23 to prevent the rubber body 1 from displacing in the housing 21.

[0040] The above are all preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
