Description

Book stand

Technical Field

The invention relates to the field of office supplies, in particular to a book stand capable of automatically contracting.

Background

Book ends of utilization on the bookshelf on the existing market are mostly paired L-shaped right-angle frame type book ends, after books are taken, the book ends are required to be manually combined, meanwhile, due to the fact that the books are taken and then lose the side, the books can fall to the east and the west, and people who need to spend considerable labor go to arrange the pendulum to be flatly placed. Particularly, in a large library archive, a part of compartments have fewer books, the existing book stand cannot put fewer books in order, and when the books are put on the book stand, the books on the book stand can be askew moved due to the fact that a part of the books press the book stand and are slightly pushed away, and certain time is needed for arrangement.

Disclosure of Invention

The invention aims to provide a book stand which is novel in structure, simple in shape and capable of automatically shrinking, brings convenience to people and saves a large amount of manpower and material resources.

In order to achieve the purpose, the invention provides the following technical scheme:

a book stand comprises a supporting plate, an underframe, a baffle, a spring, a sliding rail, a hook block, a sleeve sliding block, a clamping plate and a book stand plate; the chassis is of a channel steel structure, the baffle is fixedly connected to one end of the chassis, a sliding rail is arranged in the chassis along the length direction of the chassis, a sleeve sliding block is arranged in the sliding rail in a sliding mode, the end face of the sleeve sliding block is fixedly connected with a hook plate, one end of a spring is connected to the hook plate, the other end of the spring is fixedly connected to the baffle, and the extension direction of the spring is parallel to the sliding rail; the clamping plate is Y-shaped, the lower end of the clamping plate is inserted into the sleeve sliding block, the diameter of the lower end of the clamping plate is smaller than the inner diameter of the sleeve, the length of the lower end of the clamping plate is larger than the height of the sleeve, an opening is formed in the upper end of the clamping plate, and the book end plate is arranged in the opening in the upper end of the clamping plate.

Specifically, the slide rail welds in the chassis groove, connects convenient, firm.

Specifically, the sleeve sliding block and the hook block are connected through screws, and the spring is convenient to replace and maintain.

Preferably, the spring is a double-force spring, is not easy to damage, and reduces maintenance and replacement.

Preferably, the sleeve slider is aluminum alloy material, and is light and handy.

Compared with the prior art, the invention has the beneficial effects that:

when books are not placed on the bottom frame, the book vertical plate can automatically tighten to approach the right baffle under the action of the spring; when books are put on the book shelf, the book shelf plate is pulled to the leftmost end, and the book shelf plate slides down along the sleeve sliding block exposed outside, so that the book shelf plate is blocked by the bottom frame and kept fixed, and the books are convenient to put; after books are placed, the book end plate is slightly lifted upwards and can be automatically retracted under the tension of the spring; when books are placed on the bottom frame, the book end plate can be automatically contracted under the tension of the spring after the books are taken down, and manual arrangement is not needed.

Detailed Description

Referring to fig. 1 and 2, the book stand comprises a supporting plate 1, a bottom frame 101, a baffle plate 102, a spring 2, a sliding rail 3, a hook block 4, a sleeve sliding block 5, a clamping plate 6 and a book stand plate 7; the chassis 101 is of a channel steel structure, a baffle is fixedly connected to one end of the chassis, a slide rail 3 is arranged in the chassis along the length direction of the chassis, a sleeve slide block 5 is arranged in the slide rail in a sliding mode, a hook plate 4 is fixedly connected to the end face of the sleeve slide block 5, one end of a spring is connected to the hook plate, the other end of the spring is fixedly connected to the baffle, and the extension direction of the spring is parallel to the slide rail; the clamping plate 6 is Y-shaped, the lower end of the clamping plate is inserted into the sleeve sliding block, the diameter of the lower end of the clamping plate is smaller than the inner diameter of the sleeve, the length of the lower end of the clamping plate is larger than the height of the sleeve, an opening is formed in the upper end of the clamping plate, and the book end plate is arranged in the opening in the upper end of the clamping plate.

As shown in fig. 1, when the sleeve slider 5 is pulled to the leftmost end, i.e. the end far away from the baffle, the sleeve slider moves out of the slide rail, the lower end of the clamping plate 6 slides downwards along the sleeve, and simultaneously drives the book end plate 7 to move downwards, the lower edge of the book end plate abuts against the edge of the bottom frame 101, and because the sleeve and the book end plate are blocked by the bottom frame, the restoring force of the spring is not enough to drive the sleeve and the book end plate to slide towards the edge close to the baffle, so that the sleeve and the book end plate are kept fixed.

Referring to fig. 2, the sliding rail 3 is spot welded in the groove of the chassis 101, and the sleeve sliding block 5 and the hook block 4 are connected by screws and inserted into the sliding rail. According to the principle of mechanical deformation of the spring, when the spring is stretched, the spring gives an automatic clamping force to the book end plate, so that the book end plate and the baffle are automatically clamped, the supporting plate is welded on a notch of the groove of the bottom frame 101, and if the book end bottom frame does not contain books, the spring automatically retracts the book end plate to the baffle under the action of restoring force.

As shown in fig. 3, the clamp plate 6 is Y-shaped, the lower end of the clamp plate can be just inserted into the sleeve sliding block, and the book end plate is placed at the upper end of the clamp plate, so that the sleeve sliding block 5 can be pulled back together with the book end plate 7 when being pulled back by the spring.

As shown in fig. 1 and 2, when the book end plate 7 is placed on the bottom frame 101, the book end plate is flush with the highest point of the right baffle plate 102, when the sleeve sliding block 5 slides to the position that the edge of the bottom frame protrudes, the Y-shaped clamping plate 6 slides down along the inner wall of the sleeve, the book end plate 7 also falls downwards, and the lower edge of the book end plate 7 is blocked by the bottom frame 101, so that the sleeve sliding block 5 is not movable, the whole book end is kept to be completely unfolded, and books and archives are convenient to place; after books are placed, the book standing plate 7 is slightly lifted upwards and can be automatically retracted under the tension of the spring.

The above-described embodiments are merely preferred embodiments of the present invention, and should not be construed as limiting the present invention, and the scope of the present invention is defined by the claims, and equivalents including technical features described in the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of the invention.
