Detailed ways

Example 1

A kind of library cart as shown in Fig. 1, Fig. 2 and Fig. 3, comprises cart base plate 1, and first support bar 2, second support bar 3, the 3rd support bar are respectively installed on described cart base plate 1 4. The fourth support rod 5, the first support rod 2 and the second support rod 3 are equipped with a first support plate 6, and the third support rod 4 and the fourth support rod 5 are equipped with a second support plate 7. More than one first book support plate 8 and more than one second book support plate 9 are installed between the first support plate 6 and the second support plate 7, and the first book support plate 8 and The second book supporting plate 9 intersects to form a book storage groove; the inner side wall of the first book supporting plate 8 is provided with a first chute 11, and a first slider 12 is installed in the first chute 11, and the first sliding block 12 is installed in the first chute 11. The slide block 12 is connected with the first isolation plate 13, and the second book support plate 9 inner wall is provided with a second slide groove 14, and a second slide block 15 is installed in the second slide groove 14, and the second slide groove 15 is installed in the second slide groove 14. The slide block 15 is connected with the second isolation plate 16; the first escalator support 21 is installed on the cart bottom plate 1, and the first escalator support 21 is hingedly connected with the second escalator support 23 through the rotating shaft 22.

The first escalator bracket 21 is hingedly connected with one end of the first limiting rod 24, the second escalator bracket 23 is hingedly connected with one end of the second limiting rod 25, and the other end of the first limiting rod 24 is connected with the second limiting rod 25. The other end of the position rod 25 is hingedly connected.

A connecting rod 17 is installed between the first supporting rod 2 and the second supporting rod 3, and a T-shaped block 18 is rotatably mounted on the connecting rod 17. The block 18 cooperates with the locking groove used, and the connecting rod 17 is connected to the first escalator bracket 21 provided with the locking groove through the T-shaped locking block 18 .

The first support plate 6 and the second support plate 7 are equipped with a limit ring 31, and the limit ring 31 is sleeved on the first support rod 2, the second support rod 3, the third support rod 4 or the fourth support rod. On the rod 5, a locking bolt 32 is installed on the limiting ring 31, and the locking bolt 32 is connected with the first supporting rod 2, the second supporting rod 3, the third supporting rod 4 or the fourth supporting rod through the limiting ring 31. The support rods 5 are tightly connected.

Handrails 33 are installed on the third support bar 4 and the fourth support bar 5 , and rubber anti-slip sleeves 34 are installed on the handrails 33 . The setting of handrail 33 is convenient to push cart, and the setting of rubber anti-slip cover 34 improves the comfort of holding.

The bottom plate 1 of the trolley is provided with a water removal through hole 35 .

Universal wheels 36 are installed on the cart bottom plate 1 .

The first book support plate 8 and the second book support plate 9 obliquely intersect to form a V-shaped book storage groove.

When the library trolley described in this embodiment is in use, at first the heights of the first support plate 6 and the second support plate 7 can be adjusted according to the height of the librarian, so that oneself can conveniently take and place it on the first book support. For the books in the book storage groove formed by the plate 8 and the second book support plate 9, the installation position of the limit ring 31 can be adjusted by loosening the locking bolt 32 during adjustment, thereby adjusting the first book support plate 8 and the second book support plate 9 height; tighten the locking bolt 32 to fix the first book support plate 8 and the second book support plate 9.

Since the first book support plate 8 and the second book support plate 9 obliquely intersect to form a V-shaped book storage groove, it is convenient for books to be placed vertically. And can slide the first slider 12 in the first chute 11 so as to adjust the position of the first partition plate 13 in the V-shaped book storage groove, and can also slide the second slider 15 in the second chute 14 to adjust the second The position of the partition plate 16 in the V-shaped book storage groove, the adjacent two first partition boards 13 and the second partition board 16 promptly form the position of the book stop to limit the book, because the first partition board 13 and the second partition board 16 can Flexible sliding, so it can be flexibly adjusted according to the thickness of the book, thereby increasing the book storage capacity.

When the bookcase is too high, the escalator set next to it can be opened, thereby reducing the labor load of moving the escalator. When the escalator needs to be used, the T-shaped block 18 installed on the connecting rod 17 can be rotated first, so that the T-shaped block 18 is separated from the locking groove, so that the first escalator bracket 21 surrounds the hinge point of the first escalator bracket 21 and the cart floor 1 turn. Then the second escalator support 23 is opened, and the second escalator support 23 is rotated around the rotating shaft 22, so that the first escalator support 21 and the second escalator support 23 form an escalator relying on each other. Since the first escalator bracket 21 is hingedly connected with one end of the first stop bar 24, the second escalator bracket 23 is hingedly connected with one end of the second stop bar 25, and the other end of the first stop bar 24 is connected with the second stop bar 25. The other end of the rod 25 is hingedly connected, so the first limit rod 24 and the second limit rod 25 can limit the opening angle of the first escalator bracket 21 and the second escalator bracket 23, which improves the safety of use.

The library trolley of this embodiment is not only provided with an escalator, but also can place books vertically, and can flexibly adjust the storage distance of books, so that librarians can quickly find books and effectively improve work efficiency.
