Description

An electric book sorting ladder

technical field

The utility model relates to a book ladder used in a library, in particular to an electric book sorting ladder.

Background technique

Readers can only borrow and return the books on the upper shelf of the library bookshelves with the help of the book ladder. When returning them, they usually climb up the book ladder with the books in their hands to put them back. It is very inconvenient to carry multiple books at a time. When the library staff arranges the books on the upper shelves, two people must pass the books back and forth when they cooperate. When one person arranges, they must climb back and forth on the book ladder, which is very tiring and inefficient.

Readers want to put unnecessary books back to the original place after reading or borrowing books. Because they are not familiar with the arrangement of books on the bookshelf and cannot find the location of the books, they often place them on the bookshelf casually, which leads to the loss of books. The number one cause of mis-shelving, and lack of tools in library stacks to store such books.

Utility model content

In order to overcome the above defects, the utility model provides an electric book sorting ladder that can store books.

The technical scheme adopted by the utility model is: an electric book sorting ladder, including a climbing ladder, a motor, a backing plate, a sprocket wheel, a chain and a sorting platform. The climbing ladder includes handrails and multi-layered first pedals and second pedals arranged between the handrails, as well as supporting feet, slide bars and various connecting rods. The upper end of the slide bar is fixedly connected to the armrest, and the lower end is fixedly connected to the support foot. The climbing ladder is triangular in shape, and two universal wheels and two elastic supporting universal wheels are installed at the bottom. A motor is installed on the second pedal, and the sprocket wheel is installed on the shaft of the motor, and the sprocket wheel is used in conjunction with the chain. Both ends of the chain are affixed to the cuboid platform on the finishing platform, and the cuboid platform is affixed to the pulley through a gasket, and the pulley is two single-row pulleys. The slide bar is composed of two identical grooves at the front and rear, and there is a chute on the inner surface of the groove, and the pulley moves along the chute; the gap between the two grooves is used for passing the chain .

The beneficial effects of the utility model are: by installing the sorting platform on the book ladder, when readers can't find the position of the books on the bookshelf, they can put them on the platform and wait for the staff to handle them, reducing the phenomenon of wrong shelves and messy shelves of books ;When there are many books that need to be put back to the high-level bookshelf, the sorting platform can be raised to the opposite level to facilitate the return of books; when the staff sorts the books on the high-level bookshelf, the sorting platform can be raised to assist in completing the sorting of books.

Detailed ways

The purpose of this utility model is to provide a new type of electric book sorting ladder, as shown in Figure 1, to solve the problems raised in the above-mentioned background technology.

An electric book sorting ladder includes a climbing ladder 1, a motor 2, a backing plate 3, a sprocket 4, a chain 5 and a sorting platform 6. Described climbing ladder 1 comprises handrail 11 and is arranged on the multilayer first pedal 12 between handrail 11, second pedal 13, and support foot 14, slide bar 15 and a plurality of connecting rods 16, and described climbing ladder 1 is in the form of Triangular, two universal wheels 17 and two elastic support universal wheels 18 are installed at the bottom.

The first pedal 12 is a cuboid, the cross section of the second pedal 13 is convex, the convex lower cuboid is used as a pedal, and the convex upper cuboid is used to place the motor 2 . The motor 2 is fixedly connected with the second pedal 13 by backing plate 3, and the shaft on the motor 2 is connected with the sprocket 4 through a key. After the motor 2 is started, the shaft rotates, and the shaft can drive the The sprocket 4, the sprocket 4 can drive the chain 5.

The finishing platform 6 includes a rectangular parallelepiped platform 61 , pads 62 and pulleys 63 , as shown in FIG. 2 . The cuboid platform 61 is used to place books, and the chain 5 is fixed at the edge of the platform. The gasket 62 is fixedly connected to the pulley 63, and the pulley 63 is two single-row pulleys, and the gasket 62 is connected to the side of the cuboid platform 61 by screws.

As shown in Figure 3, the slide bar 15 is composed of two identical grooves 151, the inner surface of the groove 151 has a sliding groove 152, the pulley 63 is located between the grooves 151, along the The chute 152 slides, and there is a gap between the cuboid platform 61 and the slide bar 15 , which does not affect the movement of the finishing platform 6 in the vertical direction. The space between the two grooves 151 is used for passing the chain 5 . The upper end of the sliding rod 15 is fixedly connected to the armrest 11 , and the lower end is fixedly connected to the support foot 14 .

When the book ladder is in normal use, the finishing platforms 6 on both sides of the book ladder are in the position shown in Figure 1, which is convenient for readers and librarians to place books. When placing books, start the motor 2, the motor 2 drives the sprocket 4 to rotate, the sprocket 4 drives the chain 5, and the sprocket 5 pulls the finishing platform 6 to move along the slide bar 15. Driven by the motor 2, the finishing platform 6 on one side is raised to a position convenient for returning or sorting books, while the finishing platform 6 on the other side is lowered, which does not affect its use at this time. After use, start the motor 2 again to lower and raise the finishing platform 6 that is at a high place and a low place respectively to a suitable position that is convenient for use.

The universal wheel 17 is incompressible in the height direction relative to the book ladder, and the elastic support universal wheel 18 is compressible in the height direction. When the staff did not go up the book ladder, the four universal wheels touched the ground, and when the staff went up the book ladder, the elastically supported universal wheels 18 were compressed, and the two supporting legs all touched the ground, which played a role together with the universal wheels. supporting role.
