Description

Technical Field

[0001] This utility model relates to the field of drawing board box technology, and in particular to a drawing board box that is easy to adjust and stable to use. Background Technology

[0002] Chinese utility model patent with announcement number CN220615352U discloses a portable drawing board box, including a cover mounting plate, a telescopic rod movably connected to one side of the cover mounting plate, a threaded rod fixedly connected to one end of the top of the cover mounting plate, and a mounting block fixedly installed at the other end of the top of the cover mounting plate by screws. A fixing block is threadedly connected to the surface of the threaded rod, and a limit block is fixedly connected to one end of the telescopic rod by screws.

[0003] Although the aforementioned drawing board box solves some defects in the existing technology, it still has some shortcomings in actual use. For example, the mounting block is fixed to the end of the cover mounting plate away from the limiting block with screws. When clamping the drawing board, different sizes of drawing boards can only be clamped by adjusting the position of the limiting block. When the size of the drawing board is smaller than the length of the cover mounting plate, the drawing board cannot be effectively clamped, and the clamping range is limited.

[0004] Therefore, a drawing board box that is easy to adjust and stable to use is proposed. Utility Model Content

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Please refer to Figures 1 to 4 As shown, this embodiment provides a drawing board box that is easy to adjust and stable to use, including a storage box 1 and a cover plate 2. The lower end of the storage box 1 is hinged to the lower end of the cover plate 2 via a hinge. Angle adjustment components are provided on both opposite sides of the cover plate 2. An adjustment slot 202 is provided on the top of the cover plate 2. A fixing plate 203 for covering the adjustment slot 202 is fixedly connected to the inner side of the cover plate 2. An adjustment rod 5 is inserted into the adjustment slot 202 with adjustable height. An upper clamping plate 6 is fixedly connected to the top of the adjustment rod 5. A lower clamping plate 4 is installed with adjustable height on the side of the cover plate 2 away from the storage box 1. The lower clamping plate 4 is located below the upper clamping plate 6.

[0023] This utility model, by setting up a lower clamping plate 4 and an upper clamping plate 6 with adjustable height, can quickly clamp and fix drawing boards of different sizes, has wide applicability, and the height of the clamping drawing board can be adjusted as needed.

[0024] Furthermore, a second handle locking bolt 7 is threadedly installed on the side of the cover plate 2 near the storage box 1 to lock the adjusting rod 5 into the adjusting slot 202. By adopting the above technical solution, the height of the upper clamping plate 6 can be adjusted by tightening or loosening the second handle locking bolt 7 during use.

[0025] Furthermore, a limiting groove 201 is provided on the side of the cover plate 2 away from the storage box 1. Two limiting grooves 201 are provided. A convex slider 401 corresponding to each limiting groove 201 is fixedly connected to one side of the lower clamping plate 4. The convex slider 401 is slidably disposed in the limiting groove 201. A first handle bolt 402 is threadedly mounted on the lower end of the convex slider 401. By tightening the first handle bolt 402, the convex slider 401 can be fixed in the limiting groove 201. The above design, by providing two limiting grooves 201, can ensure the stability of the lower clamping plate 4 when supporting the drawing board. In use, the height of the lower clamping plate 4 can be adjusted by tightening or loosening the first handle bolt 402.

[0026] Furthermore, in order to ensure the stability of the drawing board when it is clamped, clamping grooves are provided at the bottom of the upper clamping plate 6 and the top of the lower clamping plate 4.

[0027] Furthermore, both sets of angle adjustment components include a connecting rod 8. Slotted holes 204 are provided on opposite sides of the cover plate 2. One end of the connecting rod 8 is hinged to one side of the storage box 1. A third handle bolt 9 is rotatably installed at the end of the connecting rod 8 away from the storage box 1. A limit slider 10 is provided on the inner side of the cover plate 2. One end of the third handle bolt 9 slides through the connecting rod 8 and the slotted hole 204 and is threaded onto the limit slider 10. With this design, in use, after opening the cover plate 2 and flipping it to the desired angle, tightening the third handle bolt 9 maintains the angle between the storage box 1 and the cover plate 2.

[0028] Furthermore, in order to facilitate lifting the storage box 1, a handle 101 is fixedly connected to the top of the storage box 1.

[0029] In this embodiment, the storage box 1 and the cover plate 2 are connected at the end away from the hinge by a latch 3.
