[0029] Reference Figure 1-4 The utility model provides a stool with high stability, including a stool body 1, a rotating shaft 2 is rotatably connected to the outer contour of the stool body 1, an adjusting column 4 is movably connected to the top of the stool body 1, a fixing plate 5 is fixedly connected to the top of the adjusting column 4, and a sealing plate 6 is hinged on the top of the fixing plate 5. A placement slot 3 is opened on the stool body 1, and a lifting mechanism is provided on the inner wall of the placement slot 3. A locking mechanism detachably connected to the sealing plate 6 is provided on the outer contour of the fixing plate 5. Through the provided lifting mechanism, the height of the items stored in the placement slot 3 can be adjusted, which is convenient for users to take. When the user needs to adjust the height of the sealing plate 6, the lifting mechanism is used to lift the adjusting column 4, so that the fixing plate 5 and the sealing plate 6 are adjusted, thereby increasing the user experience. When the user places the item in the placement slot 3, the locking mechanism is used to lock the sealing plate 6, which further increases the sealing effect and practical performance of the equipment.

[0030] The lifting mechanism includes an electric push rod 7 fixedly connected to the bottom of the inner wall of the placement groove 3, a connecting rod 8 is arranged on the top of the electric push rod 7, a placement plate 9 is arranged on the top of the connecting rod 8, a moving tube 11 is fixedly connected to the outer edge of the adjusting column 4 near the bottom, an annular moving groove 10 for the moving tube 11 to be engaged is provided on the top of the placement groove 3, a pick-up hole 14 is provided in the middle of the fixed plate 5, a through hole 13 is provided in the middle of the adjusting column 4, a mounting groove penetrating the placement groove 3 is provided at the bottom of the stool body 1, and a battery 12 is arranged in the mounting groove. When the user needs to take an item, the user opens the sealing plate 6 and then starts the electric push rod 7, and uses the electric push rod 7 to drive the placement plate 9 at the top of the connecting rod 8 to move on the inner wall of the placement groove 3, and moves the placement plate 9 to the top of the inner wall of the placement groove 3. When the top of the placement plate 9 is connected with the bottom of the adjusting column 4, the When the adjusting column 4 moves upward, the moving tube 11 at the bottom of the adjusting column 4 moves in the annular moving groove 10. When the connecting rod 8 or the placing plate 9 is damaged, the moving tube 11 is used to increase the stability of the adjusting column 4, the fixing plate 5 and the sealing plate 6, so as to avoid the problem that the adjusting column 4, the fixing plate 5 and the sealing plate 6 are separated from the stool body 1 after being damaged.

[0031] The locking mechanism includes a rotating shaft 15 rotatably connected to the outer contour of the fixed plate 5, a limiting plate 16 is arranged on the outer contour of the rotating shaft 15, a locking member is arranged on the surface of the limiting plate 16 away from the rotating shaft 15, and the locking member includes an inner hexagonal movable groove 18 opened on the limiting plate 16 away from the rotating shaft 15. The inner wall of the inner hexagonal movable groove 18 is penetrated and connected with a hexagonal locking rod 19, and a locking groove for the hexagonal locking rod 19 to be clamped is opened on the sealing plate 6. The end of the hexagonal locking rod 19 is fixedly connected to a toggle block 17, and the outer contour of the hexagonal locking rod 19 is fixedly connected to an inner hexagonal connecting ring 20. The inner wall of the inner hexagonal movable groove 18 is connected to the inner wall of the hexagonal movable groove 18. The two sides of the toggle block 17 are detachably connected with an inner hexagonal limiting ring 21, and a reset spring 22 is sleeved on the outer contour of the hexagonal locking rod 19. The two ends of the reset spring 22 are respectively in contact with the inner hexagonal connecting ring 20 and the inner hexagonal limiting ring 21. A threaded groove is provided on the outer contour of the inner hexagonal limiting ring 21, and connecting threads matching therewith are provided on both sides of the inner wall of the inner hexagonal movable groove 18. An anti-skid sleeve 171 is sleeved on the outer contour of the toggle block 17, and an anti-skid groove is provided on the outer contour of the anti-skid sleeve 171. When it is necessary to take an item, the operator pulls the toggle block 17 outward, and the anti-skid function of the toggle block 17 is increased by the anti-skid sleeve 171 and the anti-skid groove on the outer contour of the toggle block 17. When the toggle block 17 moves outward, the hexagonal connecting ring 20 of the outer contour of the hexagonal locking rod 19 is driven to move out of the locking groove provided on the sealing plate 6, so that the limiting plate 16 is rotated to the other side through the rotating shaft 15, and then the sealing plate 6 hinged to the fixed plate 5 is opened, and the items stored in the equipment are taken out by using the through hole 13 and the pick-up hole 14. After taking them out, the operator moves the toggle block 17 outward again to drive the hexagonal locking rod 19 to move into the hexagonal movable groove 18, and drives the hexagonal connecting ring 20 to squeeze the reset spring 22 through the hexagonal locking rod 19, and then closes the sealing plate 6 and the fixed plate 5. At this time, the hexagonal The locking rod 19 is aligned with the locking groove on the sealing plate 6. At this time, the toggle block 17 is loosened, and the squeezed return spring 22 is used to drive the hexagonal locking rod 19 on the inner wall of the hexagonal connecting ring 20 to move into the locking groove for clamping, thereby increasing the locking effect of the sealing plate 6 and further increasing the sealing performance of the equipment. After the return spring 22 is damaged, the operator moves the limit plate 16 to the other side, and then the operator rotates the toggle block 17 to drive the hexagonal limit ring 21 to rotate, thereby separating and disassembling the hexagonal limit ring 21 threadedly connected to the inner wall of the hexagonal movable groove 18, and the return spring 22 can be replaced at this time.

[0032] Working principle: when the user needs to take an item, the user opens the sealing plate 6 and then starts the electric push rod 7. The electric push rod 7 is used to drive the placement plate 9 on the top of the connecting rod 8 to move on the inner wall of the placement groove 3, and the placement plate 9 is moved to the top of the inner wall of the placement groove 3. When the top of the placement plate 9 contacts the bottom of the adjusting column 4, the electric push rod 7 is closed. At this time, the user takes out the item on the top of the placement plate 9 through the through hole 13 and the pick-up hole 14, and then closes the sealing plate 6. When the height of the sealing plate 6 needs to be adjusted, the user opens the electric push rod 7 again to drive the placement plate 9 on the top of the connecting rod 8 to move upward, so that the placement plate 9 drives the adjusting column 4 to move upward, thereby adjusting the height of the fixed plate 5 and the sealing plate 6 on the top of the adjusting column 4, thereby increasing the user experience.

[0033] When the toggle block 17 moves outward, the inner hexagonal connecting ring 20 of the outer contour of the hexagonal locking rod 19 is driven to move out of the locking groove provided on the sealing plate 6, so that the limit plate 16 is rotated to the other side through the rotating shaft 15, and then the sealing plate 6 hinged to the fixed plate 5 is opened, and the items stored in the equipment are taken out by using the through hole 13 and the pick-up and release hole 14. After taking them out, the operator moves the toggle block 17 outward again to drive the hexagonal locking rod 19 to move into the inner hexagonal movable groove 18, and drives the inner hexagonal connecting ring 20 to squeeze the reset spring 22 through the hexagonal locking rod 19, and then closes the sealing plate 6 and the fixed plate 5. At this time, the hexagonal locking rod 19 is aligned with the locking groove on the sealing plate 6. At this time, the toggle block 17 is released, and the squeezed reset spring 22 is used to drive the hexagonal locking rod 19 on the inner wall of the inner hexagonal connecting ring 20 to move into the locking groove for clamping, thereby increasing the locking effect of the sealing plate 6.
