Stationery box

Technical Field

The utility model relates to a writing case.

Background

At present, stationery market commodities are full of trades of Lin-Lang, most of which are considered from the aspects of decoration and modeling, and a lot of defects in the actual use process are rarely concerned. The writing case is used as a necessary tool for containing stationery and has wide application groups. In the observation of actual use, the loss of small articles in the stationery, especially the eraser, is easy to cause the stationery to have to be purchased again due to the loss in the using process, which causes a great deal of waste and inconvenience. When the eraser is used, the writing case needs to be taken out, so that the contradiction between storage and use is formed. How to avoid the loss of the eraser as much as possible under the premise of not influencing the use becomes a difficult problem.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the utility model adopts the technical proposal that: a writing case comprises a writing case body (1), an internal clapboard (2) and a rubber spring sleeve (3); the inner clapboard (2) is positioned inside the writing case body (1), and the inner clapboard (2) is provided with a clamping hole (21) with the diameter of 3 mm; the middle part of the rubber spring sleeve (3) is a spring stretching part (31); two ends of the rubber spring sleeve (3) are respectively provided with a clapboard chuck (32) and a rubber sleeve (33);

the writing case body (1) is integrally connected with the inner clapboard (2); the spring stretching part (31) is integrally connected with the clapboard clamping head (32) and the rubber sleeve (33); the rubber spring sleeve (3) is made of EVA material; the rubber spring sleeve (3) passes through the clamping hole (21); the inner partition plate (2) separates the partition plate clamping head (32) from the spring stretching part (31) and the rubber sleeve (33);

the spring stretching part (31) is formed by winding an EVA cylindrical strip with the diameter of 2mm into a spring with the overall outer diameter of 5 mm;

the clapboard clamping head (32) is a circular sheet with the diameter of 5mm and the thickness of 2 mm;

the rubber sleeve (33) is cylindrical with an opening at one end, the inner diameter is 27mm, the outer diameter is 28mm, and the height is 12 mm.

The utility model discloses creatively accomodate at the inside elasticity rubber that sets up of stationery box, neither influence the use of rubber, make things convenient for accomodating of rubber simultaneously, the probability that the rubber lost that has significantly reduced. Simple structure and convenient use.

Drawings

FIG. 1 is a schematic structural view of the present invention;

description of the drawings: 1. a writing case body; 2. an internal partition; 3. a rubber spring housing; 21. a clamping hole; 31. a spring stretching portion; 32. a clapboard clamping head; 33. a rubber sleeve.

Detailed Description

Embodiments of the present invention will be described with reference to the accompanying drawings, and it should be understood that the embodiments described herein are merely illustrative and explanatory of the present invention, and are not restrictive of the invention.

Examples

As shown in fig. 1, the writing case comprises a writing case body (1), an internal clapboard (2) and a rubber spring sleeve (3); the inner clapboard (2) is positioned inside the writing case body (1), and the inner clapboard (2) is provided with a clamping hole (21) with the diameter of 3 mm; the middle part of the rubber spring sleeve (3) is a spring stretching part (31); two ends of the rubber spring sleeve (3) are respectively provided with a clapboard chuck (32) and a rubber sleeve (33);

the writing case body (1) is integrally connected with the inner clapboard (2); the writing case body (1) and the inner clapboard (2) are made of pp plastics.

The spring stretching part (31) is integrally connected with the clapboard clamping head (32) and the rubber sleeve (33); the rubber spring sleeve (3) is made of EVA material; the material has high elasticity and low cost. The rubber spring sleeve (3) passes through the clamping hole (21); the engaging hole (21) is engaged between the separator chuck (32) and the spring stretching portion (31). The inner partition plate (2) separates the partition plate clamping head (32) from the spring stretching part (31) and the rubber sleeve (33); thus, one end of the rubber spring sleeve (3) is always clamped in the writing case (1).

The spring stretching part (31) is formed by winding an EVA cylindrical strip with the diameter of 2mm into a spring with the overall external diameter of 5mm, and the length of the spring is 50 mm; when in use, the spring is pulled open, so that the use of the eraser is ensured within a certain range, and the maximum stretching range is at least outside the writing case according to the use principle.

The clapboard clamping head (32) is a circular sheet with the diameter of 5mm and the thickness of 2 mm;

the rubber sleeve (33) is in a cylindrical shape with an opening at one end, the inner diameter is 27mm, the outer diameter is 28mm, and the height is 12 mm; the size is designed according to the most common rubber size 42 × 26 × 17mm, and the EVA material has certain elastic space, so that the rubber sleeve (33) can be extruded into any shape, and the rubber is clamped in the rubber sleeve (33).

The utility model discloses creatively accomodate at the inside elasticity rubber that sets up of stationery box, neither influence the use of rubber, make things convenient for accomodating of rubber simultaneously, the probability that the rubber lost that has significantly reduced. Simple structure and convenient use.
