[0018] Combined with the embodiments of the present utility model, the technical solutions in the embodiments 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 embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0019] At the same time, in order to clearly illustrate the technical solutions of this application, the upper side, lower side, left side, right side, front side, and rear side as shown in Figure 1 are also defined.

[0020] As shown in Figure 1 and Figure 3 this embodiment provides a flip - type pencil protection box. The pencil protection box includes a base 11, a rotating rod 12, a rotating assembly 13, and a flip - cover 14.

[0021] Specifically, the rotating rod 12 extends along the left - right direction of the pencil protection box and is hinged to the rear sides of the left and right end faces of the base 11. Around the rotating rod 12, fan - shaped limiting blocks 111 are provided on the inner walls of the left and right end faces of the base 11. The upper end face of the limiting block 111 is arranged horizontally, and the front end face is arranged vertically.

[0022] The rotating assembly 13 includes a first member 131 and a second member 132 arranged along the front - rear direction. The first member 131 is arranged on the front side of the second member 132. The first member 131 and the second member 132 are integrally formed. The first member 131 is a cuboid, and the second member 132 is a semi - cylinder. Both the left and right ends of the first member 131 are provided with a first limiting portion 1311 and a second limiting portion 1312. Both the first limiting portion 1311 and the second limiting portion 1312 are fan - shaped rings, and their rear end faces are arranged vertically. The first limiting portion 1311 is arranged above the second limiting portion 1312.

[0023] Circular through - holes 141 are provided on the rear sides of the left and right end faces of the flip - cover 14. The flip - cover 14 is sleeved on the first limiting portion 1311 and the second limiting portion 1312 through the through - holes 141 and can rotate around the through - holes 141. A fan - shaped convex block 142 is arranged in the through - hole 141. The front end face of the convex block 142 is arranged vertically, and the lower end face is arranged horizontally.

[0024] The pencil protection box includes a first state in which the flip - cover 14 is placed on the base 11, a second state in which the flip - cover 14 is opened at 90°, and a third state in which the flip - cover 14 is opened at 180°.

[0025] When the pencil protection box is converted from the first state to the second state, the flip - cover 14 rotates around the through - hole 141 until the lower end face of the convex block 142 abuts against the rear end face of the second limiting portion 1312.

[0026] When the pencil protection case is converted from the second state to the third state, the bump 142 pushes the second limiting portion 1312, causing the rotating assembly 13 to rotate around the rotating rod 12 until the rear end surface of the first limiting portion 1311 abuts against the upper end surface of the limiting block 111.

[0027] With the above settings, the pencil protection case is more flexible to use. When the user needs to continuously take out the stationery in the case, the flip cover 14 can be opened to make the pencil protection case in the second state. In this state, the pencil protection case occupies less desktop space and is not easily touched by mistake, resulting in the dropping of the pencil protection case and the stationery inside, which is convenient for the user to continuously use the pencil protection case. When the pencil protection case is in the third state, the opening angle of the flip cover 14 is larger, and the user can more conveniently rummage through and take out the stationery in the case.

[0028] When the pencil protection case is converted from the third state to the second state, the flip cover 14 rotates around the through hole 141 until the front end surface of the bump 142 abuts against the rear end surface of the first limiting portion 1311; when the pencil protection case is converted from the second state to the first state, the bump 142 pushes the first limiting portion 1311, causing the rotating assembly 13 to rotate around the rotating rod 12 until the rear end surface of the second limiting portion 1312 abuts against the front end surface of the limiting block 111.

[0029] The inner diameter of the bump 142 is larger than the outer diameter of the limiting block 111 to prevent the bump 142 from conflicting with the limiting block 111 when the flip cover 14 rotates. Specifically, the inner diameter of the bump 142 is basically the same as the outer diameter of the limiting block 111 to increase the force-bearing area between the bump 142 and the first limiting portion 1311 or the second limiting portion 1312, and avoid abrasion of the bump 142, the first limiting portion 1311 and the second limiting portion 1312.

[0030] The inner diameter of the limiting block 111 is greater than or equal to the inner diameters of the first limiting portion 1311 and the second limiting portion 1312, so that when the pencil protection case is converted between the second state and the third state, the limiting block 111 can limit the rotation angle of the rotating assembly 13. Specifically, the inner diameter of the limiting block 111 is basically the same as the inner diameters of the first limiting portion 1311 and the second limiting portion 1312 to increase the force-bearing area between the limiting block 111 and the first limiting portion 1311 or the second limiting portion 1312, and avoid abrasion of the limiting block 111, the first limiting portion 1311 and the second limiting portion 1312.

[0031] The rear end face of the flip cover 14 is provided with an arc surface 143 corresponding to the convex block 142; when the pencil protection case is converted from the second state to the third state, the lower end face of the arc surface 143 abuts against the lower end face of the first member 131 to push the rotating assembly 13 to rotate around the rotating rod 12. Specifically, an arc-shaped concave surface is provided at the rear side of the lower end face of the base 11 to prevent the arc surface 143 from conflicting with the lower end face of the base 11 when the rotating assembly 13 rotates.

[0032] A dial block 144 is provided at the front end of the flip cover 14. The user can more conveniently open the flip cover 14 through the dial block 144.

[0033] The end of the flip cover 14 around the through hole 141 is closely attached to the base 11 and the rotating assembly 13, so that the frictional force between the flip cover 14, the base 11 and the rotating assembly 13 can fix the flip cover 14 at the rotating position or enable the flip cover 14 to achieve slow descent.

[0034] In summary, the present application provides a flip-type pencil protection case. The pencil protection case includes a first state in which the flip cover 14 covers the base 11, a second state in which the flip cover 14 is opened at 90°, and a third state in which the flip cover 14 is opened at 180°, improving the flexibility of using the pencil protection case.

[0035] The above is the description of the embodiments of the present invention. Through the above description of the disclosed embodiments, those skilled in the art can implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel points disclosed herein.
