Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings.

[0033] Refer to Figure 1-3 , an embodiment provided by the present utility model: A tray support rod includes a tray body 1. The bottom end of the tray body 1 is fixedly connected to a main support rod 3. The inner wall of the bottom end of the main support rod 3 is threadedly connected to a threaded rod 15. The outer wall of the bottom end of the main support rod 3 is slidably connected to a limit cylinder 13. The top of the outer wall of the main support rod 3 is rotatably connected to a sub-rod 7. The left end of the sub-rod 7 is rotatably connected to a driven rod 16. The front end of the driven rod 16 is fixedly connected to a support plate 8. The middle of the rear outer wall of the support plate 8 is rotatably connected to an adjusting rod 22. The middle of the outer wall of the adjusting rod 22 is fixedly connected to a gear 12. Both the upper and lower outer diameters of the gear 12 are meshed and connected to a tooth plate 11. The opposite sides of the front ends of the upper and lower gears 12 are fixedly connected to clamping plates 9.

[0034] Specifically, when adjusting the clamping plate 9, first rotate the adjusting rod 22 to increase the distance between the clamping plates 9, making it easier to place the mobile phone. After placing it, reverse the adjusting rod 22 to shorten the distance between the clamping plates 9, thus ensuring greater stability of the mobile phone. When you want its position to be more comfortable and convenient for viewing, you can rotate the auxiliary rod 7 and also rotate the driven rod 16 to more conveniently adjust the position of the mobile phone. The rotation of the auxiliary rod 7 and the driven rod 16 has certain limitations to ensure that the mobile phone will not fall.

[0035] Refer to Figure 1 , Figure 5 and Figure 6 , the inner peripheral wall of the tray body 1 is slidably connected to the surrounding baffle 2. The front end of the surrounding baffle 2 is fixedly connected to the slider 18. The left and right sides of the inner wall of the slider 18 are both slidably connected to the limiting posts 19. The opposite ends of the limiting posts 19 penetrate the outer wall of the slider 18. The front end of the tray body 1 is provided with a limiting groove 21. A plurality of limiting holes with the same diameter as the limiting posts 19 are provided at both ends of the inner wall of the limiting groove 21. The opposite ends of the left and right limiting posts 19 are both fixedly connected to the adjusting plate 20. The opposite ends of the left and right adjusting plates 20 are connected by a spring 17.

[0036] Specifically, when adjusting the position of the surrounding baffle 2, press the adjusting plate 20 to make the limiting posts 19 contract into the slider 18, so that the slider 18 moves up and down on the inner wall of the limiting groove 21, thereby making the surrounding baffle 2 fixedly connected to the slider 18 move up and down. The position adjustment of the surrounding baffle 2 can make the tray body 1 place items more safely and prevent the items from being easily knocked to the ground.

[0037] Refer to Figure 1 , Figure 2 and Figure 4 , the bottom end of the limiting cylinder 13 is fixedly connected to the base 4. The motor 14 is fixedly connected inside the base 4. The bottom end of the threaded rod 15 penetrates the inner wall of the base 4 and is fixedly connected to the driving end of the motor 14. The upper outer wall of the limiting cylinder 13 is fixedly connected to the controller 10. The motor 14 is electrically connected to the controller 10. Universal wheels 5 are installed on the four sides of the bottom end of the base 4. The outer wall of the toothed plate 11 is slidably connected inside the support plate 8. The clamping plates 9 all penetrate the front outer wall of the support plate 8. The inside of the tray body 1 is hollowed out and the outer wall is slidably connected to a plurality of storage box covers 6. Handles are provided on the outer walls of the storage box covers 6.

[0038] Specifically, when adjusting the up and down position of the tray body 1, the controller 10 can be used to start the motor 14 to change the up and down position of the main support rod 3, thereby driving the tray body 1 to move together. This is beneficial for the user to be more convenient and comfortable during use. The storage space under the tray body 1 can be opened and closed through the handles on the storage box covers 6, improving the space utilization efficiency of the device.

[0039] Working principle: During use, the forward and reverse rotations of the driving end of the motor 14 can be electrically controlled through the controller 10 to rotate the threaded rod 15, so that the main support rod 3 slides up and down on the inner wall of the limit cylinder 13, thereby adjusting the tray body 1 above the main support rod 3 to a suitable position to improve the convenience for the user. The presence of the surrounding baffle 2 can prevent the items on the tray body 1 from accidentally falling to the ground during use. The position of the surrounding baffle 2 can be adjusted. Press the adjusting plate 20 to compress the spring 17 so that the outer end of the limit post 19 contracts into the inner wall of the slider 18, thereby adjusting the different positions of the slider 18 in the limit groove 21. Releasing the adjusting plate 20 can fix the slider 18 at the positions of different limit holes in the limit groove 21 through the action of the spring 17 and the limit post 19. There is a support frame for mobile phones or tablets on the secondary rod 7 of the main support rod 3. During use, rotate the adjusting rod 22 to make the gear 12 rotate. The forward and reverse rotations of the gear 12 can adjust the position of the toothed plate 11, thereby driving the clamping plate 9 to move to conveniently adapt to the bottom edge of the mobile phone or tablet. The secondary rod 7 and the driven rod 16 can also be rotated to adjust the mobile phone or tablet to a comfortable position. When wanting to adjust the position of the entire device, the device can be directly pushed. The universal wheels 5 at the lower end of the base 4 can facilitate the movement of the device.
