Abstract

The utility model discloses an automatic telescopic bookend comprising two baffle plates (5) and a base plate connected with the two baffle plates. The base plate is composed of an inner base plate (1) and an outer base plate (2); the outer base plate (2) is sleeved on the inner base plate (1); the inner side wall of the outer base plate (2) is provided with a retaining ring (3); springs (4) are arranged between the inner base plate (1) and the outer base plate (2); one end of each spring (4) is arranged on a plate edge of the inner base plate (1) opposite the outer base plate (2); and the other end of each spring (4) is connected with the retaining ring (3). When a book is drawn out of the book end, the distance between the two baffle plates is automatically adjusted under the contractility action of the springs, so that other books are prevented from falling; and a plurality of retaining rings are arranged in different distances where the inner side of the outer base plate is apart from the side wall, so that different retaining rings are chosen to grapple the springs to adjust the distance between the two baffle plates of the bookend according to the book numbers.

Description

Automatic shrinking bookend

Technical field

The utility model belongs to a kind of stationery, specifically a kind of book end that can automatically shrink.

Background technology

As everyone knows; traditional book end only is comprised of two discrete baffle plates; after book end, extracting books; often can make other book swing to a side owing to having stayed larger gap; even other books do not fall; also need the artificial two baffle plate distances of adjusting to fix remaining books, very inconvenient.

Summary of the invention

The purpose of this utility model is a kind of book end of design, and this book end can shrink automatically, thereby while having avoided the extraction books, because the problem of other books is done down greatly in gap.

The technical solution of the utility model is: automatic shrinking bookend, the base plate that comprises two baffle plates and be connected with two baffle plates respectively, base plate is made as the inside and outside inner bottom plating be nested, Outer Bottom Plating, the Outer Bottom Plating madial wall is provided with clasp, between inner bottom plating and Outer Bottom Plating, be provided with spring, one end of spring is located on inner bottom plating with the relative plate of Outer Bottom Plating along upper, and the other end of spring is connected with clasp.

As a kind of improvement of the present utility model, the Outer Bottom Plating inboard is provided with many cover clasps apart from baffle plate different distance place.

The beneficial effects of the utility model: two baffle plates of book end can draw in automatically, leaving gap while having avoided extracting certain books and need readjust the problem that two baffle plates distances even fall other books.

The accompanying drawing explanation

Fig. 1 is the structure perspective view of book end.

Fig. 2 is the snap link schematic diagram of Outer Bottom Plating shown in Figure 1 inside edge.

In figure: inner bottom plating 1, Outer Bottom Plating 2, clasp 3, spring 4, baffle plate 5.

The specific embodiment

As Fig. 1, the utility model automatic shrinking bookend comprises two baffle plates 5 and the base plate be connected with two baffle plates 5 respectively, base plate is made the inside and outside inner bottom plating be nested 1, Outer Bottom Plating 2, clasp 3 is housed on the Outer Bottom Plating madial wall, the sidewall of inner bottom plating 1 connects two springs 4, the other end of two springs 4 is hooked on the clasp 3 of Outer Bottom Plating sidewall, and the contact-making surface of inside and outside base plate 1,2 is level and smooth.Like this, after extracting certain books out, under the convergent force effect of spring 4, automatically adjust the distance of two baffle plates 5, avoided other books to fall.As Fig. 2, be the inboard schematic diagram of Outer Bottom Plating, clasp 3 can be provided with many covers apart from baffle plate 5 different distance in Outer Bottom Plating 2 inboards, like this, according to the number of books, can select different clasp 3 to hook spring 4 to adjust two baffle plate distances of book end.

Claims

1. automatic shrinking bookend, the base plate that comprises two baffle plates (5) and be connected with two baffle plates respectively, it is characterized in that: described base plate is made as the inside and outside inner bottom plating be nested (1), Outer Bottom Plating (2), Outer Bottom Plating (2) madial wall is provided with clasp (3), between inner bottom plating (1) and Outer Bottom Plating (2), be provided with spring (4), one end of spring (4) is located at inner bottom plating (1) plate that above same Outer Bottom Plating (2) is relative along upper, and the other end of spring (4) is connected with clasp (3).

2. automatic shrinking bookend according to claim 1, is characterized in that: cover clasps (3) more than Outer Bottom Plating (2) inboard is provided with apart from baffle plate (5) different distance place.
