Description
Technical Field
[0001] The utility model relates to the technical fields of book management and transportation, and particularly relates to a book cart with a telescopic sorting table. Background Art
[0002] Book carts are widely used transportation carriers in libraries. For tasks such as the shelving of new books in the library, the return of borrowed and returned books by readers, and the shifting of books on different bookshelves, book carts are often needed for the short-distance transportation and handling of books within the library.
[0003] Library staff need to place books on the book cart before uniformly filing and placing them on the corresponding bookshelves. First, the staff has to sort out the disordered books, carefully check the call numbers on the book labels, and roughly arrange the books of the same category or similar call numbers in order, for example, arranging them in the order of library classification numbers A - Z, and then placing the books on the bookshelf in sequence.
[0004] The structures of the book carts currently used in libraries are relatively simple and the overall functions are single. For a normal book cart, its width dimension is relatively fixed and the dimension range needs to meet the design standards and match the spacing between library bookshelves. Therefore, the size of its support plate is limited. This will have the following deficiencies: When there are fewer books, simple searching and sorting work can be carried out on the book cart. However, when there are more books or they are stacked together, there is not enough space on the book cart for operation, making it inconvenient to sort the books. Summary of the Invention
[0005] The purpose of the utility model is to provide a book cart with a telescopic sorting table for the problems existing in the prior art.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A book cart with a telescopic sorting table includes an open body. There is at least one layer of support plate inside the body. A slidable sorting table is arranged below the support plate, and the sorting table is arranged parallel to and close to the support plate. A telescopic bracket is rotatably connected below the sorting table. The telescopic bracket includes a support sleeve rotatably connected to the sorting table and a movable column sleeved and connected to the support sleeve. A locking member acting on the movable column is also arranged on the support sleeve.
[0008] Through the arrangement of the sorting table, the support area of the book cart used in this library can be expanded by nearly twice after it is unfolded, which is convenient for librarians to sort, classify, and sequence the books on the book cart, improving the efficiency of book filing. After the sorting table is retracted, it becomes an ordinary book cart and does not occupy too much area.
[0009] The provision of the telescopic support can support the sorting table after it extends, enhancing the stability of the support. The telescopic arrangement of the support sleeve and the movable column also facilitates height adjustment and storage in a non-expanded state.
[0010] Further, the vehicle body includes a bottom plate, and vertical side plates provided on both sides in the length direction of the bottom plate. A horizontally arranged support plate is provided between a pair of the vertical side plates. A universal wheel with a foot brake is also provided below the bottom plate. The book cart with this structure is simple in structure and convenient to use.
[0011] Further, both sides in the length direction of the sorting table are respectively connected to the vehicle body through flat push rails, so that the sorting table can slide; the width of the sorting table is not greater than the width of the support plate, and a handle is further provided on the outer edge of the sorting table, which is convenient for pulling out the sorting table.
[0012] Further, the lower part of the sorting table is connected to the support sleeve through a hinge seat or a universal joint, and the length of the support sleeve does not exceed the width of the sorting table.
[0013] Further, a support foot or a moving wheel is provided at the lower end of the movable column.
[0014] In some embodiments, there is one telescopic support, which is arranged in the middle of the sorting table.
[0015] In some embodiments, there is a pair of symmetrically arranged telescopic supports, which are respectively arranged at the corners of the sorting table.
[0016] Further, an elastic buckle is also provided below the sorting table. The elastic buckle has a buckle seat, and a pair of arc-shaped clamping arms provided on the buckle seat. Arc-shaped limiting protrusions are provided on the inner side of the arc-shaped clamping arms. The buckle seat is connected to the sorting table by screws. The pair of arc-shaped clamping arms are used to clamp the telescopic support in the storage state to prevent it from rotating or dropping.
[0017] In some embodiments, the sorting table is two layers arranged up and down, and the extending directions of the two layers of the sorting table are arranged in opposite directions.
[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. Through the setting of the sorting table, the supporting area of the book trolley used in this library can be expanded by nearly one time after it is unfolded, which is convenient for librarians to sort, classify, and sequence the books on the book trolley, improving the efficiency of book filing; after the sorting table is retracted, it becomes an ordinary book trolley without occupying too much area. 2. The setting of the telescopic bracket can support the sorting table after the sorting table extends, improving the stability of the support. The telescopic setting of the support sleeve and the movable column is also convenient for height adjustment and storage in the non-unfolded state. 3. Movable wheels are arranged below the telescopic bracket, facilitating its movement together with the book trolley in the unfolded state, further improving its flexibility. 4.

[0028] As Figures 1 to 3 shown, a book cart with a telescopic sorting table includes an open vehicle body. At least one layer of support plate 3 is provided inside the vehicle body. A slidable sorting table 4 is provided below the support plate 3, and the sorting table 4 is arranged parallel to and close to the support plate 3. A telescopic bracket 6 is rotatably connected below the sorting table 4. The telescopic bracket 6 includes a support sleeve 601 rotatably connected to the sorting table 4 and a movable column 602 sleeved and connected to the support sleeve 601. A locking member acting on the movable column 602 is further provided on the support sleeve 601, and the locking member may be a locking screw 603.
[0029] Through the arrangement of the sorting table 4, the book cart used in this library can expand the support area by nearly twice after it is unfolded, which is convenient for librarians to sort, classify and sequence the books on the book cart, and improves the efficiency of book filing. After the sorting table 4 is retracted, it becomes an ordinary book cart and does not occupy too much area.
[0030] In this embodiment, a sorting table 4 is provided below the uppermost support plate 3. The width dimension of the book cart, which is also the width dimension of the support plate, is a normal size so that it is suitable for the spacing between most library bookshelves. The spacing between bookshelves in a library is usually about 100 cm, generally not less than 75 cm, to facilitate the passage of personnel and ensure the convenience of retrieving books. When the spacing reaches 120 cm, a book cart can be easily placed between them. Books to be consulted or sorted can be placed on the book cart for convenient handling. That is to say, the normal width of the book cart is not too large (within 50 cm). However, when the librarian is sorting, classifying, and sequencing, a certain operating space is required. If the support surface is too narrow, it is not conducive to operation. Therefore, the present utility model sets a slidable sorting table, which can increase the support area of the uppermost support plate when needed, facilitating the librarian to sort books. This improvement is a reasonable improvement based on the actual layout spacing of library bookshelves and the size of the book cart.
[0031] The setting of the telescopic support 6 can support the sorting table 4 after the sorting table 4 extends, improving the stability of the support. The telescopic setting of the support sleeve 601 and the movable column 602 is also convenient for height adjustment and storage in the non-expanded state.
[0032] Specifically, after the sorting table 4 extends, the telescopic supports 6 fixed at both outer ends of the lower part of the sorting table 4 can be vertically rotated 90 degrees towards the ground, effectively improving its support stability and preventing sliding, facilitating the improvement of the practicality and functionality of the overall structure and better carrying out the support work.
[0033] Rotate the locking screw 603, and the movable column 602 in the support sleeve 601 can slide out, extend to the ground, and then rotate the locking screw 603 to lock and fix the movable column 602, playing a supporting role for the sorting table 4.
[0034] Conversely, rotate and loosen the locking screw 603, the movable column 602 can retract into the support sleeve 601, and then rotate the locking screw 603 to lock and fix the movable column 602, so that the telescopic support 6 can be retracted, facilitating the sorting table 4 to slide back under the support plate 3.
[0035] Furthermore, the vehicle body includes a bottom plate 1 and vertical side plates 2 provided on both sides of the bottom plate 1 in the length direction. A horizontally arranged support plate 3 is provided between a pair of the vertical side plates 2. A universal wheel 7 with a foot brake is also provided below the bottom plate 2.
[0036] The structure of the vehicle body is simple and easy to use. The universal wheel 7 with a foot brake facilitates its movement. A push-pull handle can also be provided on the vertical side plate 2 to facilitate the librarian to move the book cart.
[0037] In some embodiments, the upper surfaces of the bottom plate 1, the support plate 3 and the sorting table 4 are respectively provided with anti-slip patterns, and limiting baffles are respectively provided on both sides in the width direction; the anti-slip patterns can increase the friction force to prevent books from sliding and falling to the ground, and the limiting baffles can play a role in edge blocking. The combined setting with the anti-slip patterns can effectively prevent books from falling.
[0038] Further, both sides in the length direction of the sorting table 4 are respectively connected to the vehicle body through flat push rails 5. The flat push rails 5 facilitate the sliding operation of the sorting table 4. The flat push rails 5 are similar to the structure of drawer rails, including an outer fixed rail connected to the vertical side plate and an inner fixed rail connected to the side of the sorting table. Components such as an intermediate fixed rail, balls, and a retainer are also provided between the outer fixed rail and the inner fixed rail.
[0039] The width of the sorting table 4 is not greater than the width of the support plate 3, preferably equal to or slightly smaller than the width of the support plate 3. When it extends, it can increase the operating area, and when it retracts, neither side will be exposed; a handle is also provided on the outer edge of the sorting table 4 for convenient pulling of the sorting table.
[0040] Further, the lower part of the sorting table 4 is connected to the support sleeve through a hinge seat 9 or a universal joint, enabling the support sleeve to rotate. It can be connected through a damping rotating shaft to have a damping feeling during rotation, and a limit is set at 90 degrees to enable it to stop at 90 degrees. The length of the support sleeve 601 does not exceed the width of the sorting table 4, so that when it is folded and stored, it can be completely under the sorting table 4, that is, under the support plate 3, and the end will not protrude, which is both beautiful and can reduce bumps.
[0041] Further, a support foot or a moving wheel 8 is provided at the lower end of the movable column 602, and both forms are acceptable; if the moving wheel 8 is provided, it is convenient to move together with the book cart in the unfolded state, further improving its flexibility.
[0042] In some embodiments, as shown in Figure 5 There is one telescopic support 6, which is arranged in the middle of the sorting table 4. This arrangement is the simplest, with low cost, and can also play a certain supporting role.
[0043] In some embodiments, as shown in Figure 1 There are a pair of symmetrically arranged telescopic supports 6, which are respectively arranged at the corners of the sorting table. This method can balance the support stability and cost.
[0044] Further, in combination with Figure 4As shown, an elastic buckle 10 is also provided at the bottom of the organizing table 4. The elastic buckle 10 has a buckle seat 1001 and a pair of arc-shaped clamping arms 1002 arranged on the buckle seat 1001. The arc-shaped clamping arms 1002 are provided with an arc-shaped limiting protrusion 1003 on the inner side. The buckle seat 1001 is provided with an inner countersunk hole, which can be connected to the organizing table 4 by screws. The pair of arc-shaped clamping arms 1002 are used to clamp the telescopic and retractable bracket in the storage state.
[0045] By using the setting of the elastic buckle 10, the retractable bracket 6 can be clamped and bound after being folded to prevent it from falling and shaking. The elastic buckle 10 has a simple structure and is easy to use. The support sleeve 601 can be pressed into the area between a pair of arc-shaped clamping arms 1002 to clamp the support sleeve 601 under the elastic force of the arc-shaped clamping arms 1002. When it needs to be unfolded, it can be separated by lightly pressing downward or bending. The setting of the arc-shaped limiting protrusion 1003 can form a clamping limit well. The arc-shaped clamping arm 1002 and the arc-shaped limiting protrusion 1003 are both elastic structures. For example, the arc-shaped clamping arm is a metal spring sheet, and the limiting protrusion is a metal elastic strip, and the outside of both is wrapped and covered with rubber. Example 2
[0046] This embodiment provides another structure of the tidying table, such as Figure 6 As shown, the tidying table 4 is composed of two layers arranged up and down, and the two layers of the tidying table 4 extend outward in opposite directions, that is, the tidying table 4 can extend out from both sides of the support plate. This structural form can further increase its tidying area and improve its scope of application.
[0047] With this structure, the book cart can be used in places where the distance between bookshelves is large, so as to meet the needs of sorting and transporting more books. Of course, this structure can also be extended on one side and used between bookshelves with normal spacing, or it can be completely left without extending the sorting table and used as an ordinary book cart.
[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
