Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] Please see Figures 1-4 This utility model provides a convenient fixed drawing board bag, which includes a drawing board bag for storing and carrying a drawing board 7. The top of the drawing board bag is provided with a carrying strap 3 to facilitate the user to carry and move the drawing board bag, making it more convenient to bear force. The drawing board bag is assembled from a main bag 1 and a secondary bag 2. The main bag 1 is used to increase functionality, while the secondary bag 2 is used to store the drawing board 7. The secondary bag 2 is provided with a placement board 6 inside, and the drawing board 7 is installed inside the placement board 6. After the drawing board bag is supported, the user can use the placement board 6 to place the drawing board 7 on the top for sketching work, which is convenient to use and bear force. The lower end of the main bag 1 is provided with an openable main zipper 4 along the middle. The main zipper 4 is designed to open on both sides, so as to facilitate the angle rotation of the support arm and also to tilt the drawing board 7 for use. The secondary bag 2 is provided with an openable secondary zipper 5 on one side of the outer edge, so that the secondary bag 2 can be opened and flipped open for use.

[0029] A rotating rod 9 is installed at the upper part of the main package 1, and mounting plates are provided on both sides of the rotating rod 9 to connect with the main package 1. Support arms are rotatably installed on both sides of the rotating rod 9 in pairs, and the upper end of each support arm is provided with a rotating hole 10 to rotatably connect with the rotating rod 9. This makes it easy to support the drawing board bag under the force of the top, and facilitates the rotation of the support arms under the action of the rotating rod 9. The opening of the angle of the support arms provides stable support for the drawing board bag.

[0030] The support arm includes a first support arm 8 connected to the rotating rod 9, which is located inside the main package 1 for support. A second support arm 11 is slidably installed inside the first support arm 8, and a third support arm 12 is slidably installed inside the second support arm 11. This arrangement of multiple supports increases the overall length of the support, facilitating use at different heights. The outer sides of the second support arm 11 and the third support arm 12 are respectively provided with several penetrating first positioning holes 13 and second positioning holes 14, allowing for height adjustment and improved working efficiency. Furthermore, the outer sides of both the first support arm 8 and the second support arm 11 are equipped with... A fixing component is installed to secure the support and prevent it from sliding down during support. The fixing component includes a main frame 18 installed on one side of the bottom end of the first support arm 8 and the second support arm 11. A "Z"-shaped rocker 19 is installed in the middle of the main frame 18, forming a rocker structure. Pushing one end can lift the other end, facilitating the pulling of the support arm. The main frame 18 is located inside the main package 1, reducing unnecessary damage. A force-bearing block 110 is provided in the middle of the rocker 19. A fixing rod 111 is provided in the middle of the main frame 18 and is rotatably connected to the force-bearing block 110, so that the rocker 19 can rotate from the middle. A push block is provided at the upper end of the rocker 19. A pusher block 115 penetrates the outer side of the main frame 18, allowing the other end of the rocker 19 to be lifted by pressing the pusher block 115, thus pulling up the fixing pin 112. The bottom end of the rocker 19 is provided with a fixing pin 112 that passes through a through hole 113 and connects to the first positioning hole 13 and the second positioning hole 14, facilitating the downward pulling of the first support arm 8 and the second support arm 11. One side of the bottom end of the first support arm 8 and the second support arm 11 has a through hole 113, allowing the fixing pin 112 to be inserted and fixed inside the first positioning hole 13 and the second positioning hole 14. The other side of the lower end of the rocker 19 is provided with a spring 114 connected to the main frame 18. Under the elastic force of the spring 114, when no force is applied, the spring 114 inserts and fixes the fixing pin 112. When force is applied, the spring 114 is compressed, causing the fixing pin 112 to spring back. A connecting rod 17 is provided at the bottom end of the third support arm 12, and a support plate 15 is installed at the bottom end of the third support arm 12. A rotating platform 16 is provided at the upper end of the support plate 15 and is rotatably connected to the connecting rod 17. Several pointed cones are installed at the bottom end of the support plate 15, which enhances the stability of the support arm under the action of the support plate 15, so as to avoid the problem of tipping over during use. Furthermore, the pointed cones make the stability effect better after being inserted into the ground.

[0031] Working principle: In use, first open the main bag 1 and the secondary bag 2 through the main zipper 4 and the secondary zipper 5. Then press the push block 115 on the outer main frame 18 of the first support arm 8 to make the rocker arm 19 pull up the fixing pin 112, thereby pulling down the inner second support arm 11. After determining the position of the pulled-down position through the first positioning hole 13, the fixing pin 112 is inserted into the interior for fixation. Then, press the push block 115 on the second support arm 11 in the same way to pull down the third support arm 12. After determining the position, the fixing pin 112 is inserted into the second positioning hole 14 for fixation. Then, according to the required support angle, the rotation angle of the upper rotating rod 9 and the rotating hole 10 of the support arm is turned downward, so that the pointed cone at the lower end of the support plate 15 strengthens the stability of the drawing board bag. After opening the secondary bag 2, the drawing board 7 can be used under the action of the placement plate 6, thus completing the work.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
