Abstract
Description
Technical Field
[0001] This utility model relates to the field of desk technology, and in particular to a multifunctional desk. Background Technology
[0002] School desks, originating from the earliest octagonal tables in classrooms, should be standardized for use in schools. Currently, most desks consist of a tabletop, drawers, and a support frame. However, the space inside the drawers is limited. For students with heavy workloads, numerous materials, and many books, the drawer space is insufficient. They are forced to pile materials and books on the tabletop, thus taking up valuable space and hindering usability. Utility Model Content
[0003] This utility model provides a multifunctional desk that solves the problems in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A multifunctional desk includes a drawer at the bottom of the desk and a support at the bottom of the desk. The bottom of the drawer is connected to a mounting plate with a "U" shaped cross-section. A screw is rotatably connected to one side of the support, and connecting blocks are threaded to both sides of the screw. A first mounting block is connected to the surface of the connecting block, and a first rotating shaft is connected to the surface of the first mounting block. A support bar is connected to the surface of the first rotating shaft. A second rotating shaft is connected to the other end of the support bar, and a second mounting block is connected to one side of the second rotating shaft. A base plate is connected to the bottom of the second mounting block.
[0006] The top of the mounting plate has multiple grooves at equal intervals, and the inside of the grooves is connected to a telescopic tube that is connected to the base plate.
[0007] As a further description of the above technical solution:
[0008] The bottom of the drawer is equipped with a slide groove, and a slider connected to the connecting block is slidably connected inside the slide groove.
[0009] As a further description of the above technical solution:
[0010] The threads on both sides of the screw surface are arranged in opposite directions.
[0011] As a further description of the above technical solution:
[0012] The telescopic tube includes a sleeve that connects to the inside of the groove, and the sleeve is movably connected to a connecting rod that connects to the top of the base plate.
[0013] As a further description of the above technical solution:
[0014] The surface of the bracket is rotatably connected to a rotating rod, and the surface of the rotating rod is connected to a horizontal plate, with a wastebasket being snapped into place at the top of the horizontal plate.
[0015] As a further description of the above technical solution:
[0016] The surface of the bracket is connected to a baffle for blocking the horizontal plate.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0018] 1. In this utility model, by rotating the screw, the connecting block can move the support bar, the base plate, and the connecting rod, etc. The moved base plate, connecting rod, and mounting plate can form a storage space, so that students can put some learning materials or books into the space, avoiding the drawer space being insufficient and occupying the tabletop area, thus affecting the students' normal use.
[0019] 2. In this utility model, the wastebasket is designed to allow students to dispose of trash generated during study or large amounts of used tissues when they have a cold, thus avoiding the inability to dispose of large amounts of tissues or trash during class. At the same time, the wastebasket can be rotated to a designated position by rotating the lever. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figures 1-4 A multifunctional desk includes a drawer 2 at the bottom of a tabletop 1 and a support 3 at the bottom of the tabletop 1. The bottom of the drawer 2 is connected to a mounting plate 4 with a "U"-shaped cross-section. A screw 5 is rotatably connected to one side of the support 3, and connecting blocks 6 are threaded onto both sides of the screw 5. A first mounting block 7 is connected to the surface of the connecting block 6, and a first rotating shaft 8 is connected to the surface of the first mounting block 7. A support bar 9 is connected to the surface of the first rotating shaft 8, and a second rotating shaft 10 is connected to the other end of the support bar 9. A second mounting block 11 is connected to one side of the second rotating shaft 10, and a support bar 11 is connected to the bottom of the second mounting block 11. The top of the base plate 12 and the mounting plate 4 are provided with multiple grooves 13 at equal intervals. The inside of the grooves 13 is connected to the telescopic tube connected to the base plate 12. By rotating the screw 5, the connecting blocks 6 threaded on both sides of its surface drive the support bar 9 and the base plate 12 to move. At the same time, the base plate 12 can also drive the connecting rod 15 to move inside the sleeve 14, so that the base plate 12, the connecting rod 15 and the mounting plate 4 can form a storage space. This allows students to conveniently put books and other materials into the space, avoiding the problem of books and study materials taking up the area of the tabletop 1 and affecting students' learning.
[0028] Furthermore, a slide groove is installed at the bottom of drawer 2, and a slider connected to the connecting block 6 is slidably connected inside the slide groove. This is to facilitate the movement of the connecting block 6, which is threaded on the surface of the screw 5, inside the slide groove via the slider when the screw 5 is rotated.
[0029] Furthermore, the threads on both sides of the screw 5 are arranged in opposite directions, which is to facilitate the simultaneous movement of the connecting blocks 6 on both sides of the screw 5 towards each other or in opposite directions when the screw 5 rotates.
[0030] Furthermore, the telescopic tube includes a sleeve 14 connected to the inside of the groove 13, and a connecting rod 15 connected to the top of the base plate 12 is movably connected inside the sleeve 14. The multiple sleeves 14 and connecting rods 15 are designed to cover the left, right and rear sides of the base plate 12 and the mounting plate 4, preventing books or study materials from falling when placed on them.
[0031] Furthermore, a rotating rod 16 is rotatably connected to the surface of the bracket 3, and a horizontal plate 17 is connected to the surface of the rotating rod 16. A wastebasket 18 is snapped onto the top of the horizontal plate 17. The wastebasket 18 needs to be lined with a garbage bag during use. A nut is threaded onto the surface of the rotating rod 16, and one side of the nut is in tight contact with the surface of the bracket 3 to increase friction and prevent the bracket 3 from rotating under slight force, causing the rotating rod 16 to drive the horizontal plate 17 to rotate.
[0032] Furthermore, the surface of the support 3 is connected to a baffle 19 for blocking the horizontal plate 17, which is to prevent the rotating rod 16 from rotating the horizontal plate 17 and the wastebasket 18 to the other side of the support 3, so as to prevent students from bumping into the horizontal plate 17 or the wastebasket 18 when walking after class.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
