Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, an embodiment of the present invention provides a pigment coloring device for preschool education, including a fixed plate 1, a support plate 2 is fixedly installed on the left and right sides of the rear side of the top of the fixed plate 1, a storage box 3 is fixedly installed on the top of the support plate 2, a movable cover 4 is hinged on the top of the storage box 3, a discharge port 5 is opened inside the bottom end of the storage box 3, a round rod 6 is movably sleeved inside the front of the storage box 3, a round plate 7 is fixedly installed on the front of the round rod 6, a first spring 8 is fixedly connected to the back of the round plate 7, the other end of the first spring 8 is fixedly connected to the front of the storage box 3, an extrusion plate 9 located inside the storage box 3 is fixedly connected to the rear end of the round rod 6, the outer surface of the extrusion plate 9 is movably connected to the inner surface of the storage box 3, the top of the extrusion plate 9 is movably connected to the bottom of the movable cover 4, a second spring 10 is fixedly installed on the rear side of the inner surface of the storage box 3, the other end of the second spring 10 is fixedly connected to a closing plate 11, and the outer surface of the closing plate 11 is movably connected to the inner surface of the storage box 3.

[0021] The operator can store the pigment inside the storage box 3. When the pigment is needed, the operator can press the circular plate 7 inward so that the round rod 6 pushes the extrusion plate 9 to move inward. At this time, the pigment will push the closing plate 11 to move backward, so that the closing plate 11 releases the sealing effect on the discharge port 5, and the pigment can be squeezed out through the discharge port 5, making it convenient for the operator to take the pigment at any time.

[0022] Among them, the inside of the left and right sides of the front of the storage box 3 are movably connected with the first circular shaft 12, and the outer surface of the first circular shaft 12 is fixedly connected with a rotating rod 13. There are two rotating rods 13, and the bottom of the two rotating rods 13 are hinged with movable rods 14. The outer surface of the movable rod 14 is movably connected to the inner wall of the circular rod 6, and the outer surface of the movable rod 14 is movably connected to the inner wall of the storage box 3.

[0023] When the movable rod 14 is located inside the round rod 6, it will fix the round rod 6 so that the round rod 6 cannot move.

[0024] Among them, a second circular shaft 15 is movably sleeved in the middle of the front of the storage box 3, a rotating plate 16 is fixedly sleeved on the outer surface of the second circular shaft 15, the bottom of the rotating plate 16 is hinged to the top of the movable rod 14, and a rotating block 17 located on the front of the storage box 3 is fixedly sleeved on the outer surface of the second circular shaft 15.

[0025] The operator can rotate the rotating block 17 to drive the second circular shaft 15 to rotate, so that the rotating plate 16 can drive the movable rod 14 to move.

[0026] A slide groove 18 is provided on both the left and right sides of the top of the fixed plate 1 , a slider 19 is movably installed inside the slide groove 18 , and a palette 22 is fixedly installed on the front side of the top of the fixed plate 1 .

[0027] The outer surface of the slider 19 is smooth, so that the slider 19 can move more smoothly inside the slide groove 18 .

[0028] There are two sliders 19 , and a moving plate 20 is fixedly installed on the top of the two sliders 19 . The bottom of the moving plate 20 is movably connected to the top of the fixed plate 1 , and a paint tray 21 is fixedly sleeved inside the moving plate 20 .

[0029] The operator can move the movable plate 20 to drive the paint tray 21 filled with paint to move, and then adjust the position of the paint tray 21 to make it easier for children to take the paint.

[0030] Among them, support frames 23 are fixedly installed on both left and right sides of the front side of the bottom of the fixed plate 1, and protective plates 24 are fixedly connected between the support frames 23.

[0031] By providing the protection plate 24 , the protection plate 24 can play a protective role.

[0032] A mounting block 25 is fixedly installed on the top of the inner surface of the support frame 23 . There are two mounting blocks 25 . A double-threaded rod 26 is movably sleeved between the two mounting blocks 25 . A rotating plate 27 is fixedly connected to the right end of the double-threaded rod 26 .

[0033] The operator can rotate the rotating plate 27 to drive the double-threaded rod 26 to rotate.

[0034] Among them, the left and right sides of the outer surface of the double-threaded rod 26 are threadedly sleeved with moving blocks 28, the outer surface of the moving block 28 is movably connected to the back side of the protective plate 24, the top of the moving block 28 is internally hinged with a hinged rod 29, the top of the hinged rod 29 is hinged with a top plate 30, and the top of the top plate 30 is fixedly installed with an anti-slip pad 31.

[0035] The threads on the left and right sides of the outer surface of the double-threaded rod 26 are in opposite directions, so that when the double-threaded rod 26 rotates, it can drive the two moving blocks 28 to move towards or away from each other.

[0036] A limiting groove 32 is formed inside the support frame 23 , and a limiting block 33 is movably connected inside the limiting groove 32 . The outer surface of the limiting block 33 is fixedly connected to the outer surface of the top plate 30 .

[0037] By providing the limit block 33 , the limit block 33 can limit the top plate 30 , so that the top plate 30 can rise or fall more stably.

[0038] Working principle and usage process: After placing the fixed plate 1 as a whole on the tabletop, the operator can rotate the rotating plate 27 so that the double-threaded rod 26 drives the two moving blocks 28 to move in opposite directions, so that the hinged rod 29 can push the top plate 30 and the anti-slip pad 31 to move upward, and then the anti-slip pad 31 and the fixed plate 1 cooperate to clamp the edge of the table, so that the fixed plate 1 as a whole can be stably placed on the tabletop, which makes it more stable for young children to use it and prevents young children from knocking over the fixed plate 1 as a whole.

[0039] Due to the design of the movable rod 14, when the movable rod 14 is located inside the round rod 6, it can fix the round rod 6, so that the round rod 6 cannot move, thereby preventing the child from pressing the round plate 7 and causing paint waste. The operator can store the paint inside the storage box 3. When the paint needs to be used, the rotating block 17 can be rotated to make the rotating block 17 drive the second round shaft 15 to rotate, thereby causing the rotating plate 16 to rotate. The rotating plate 16 cooperates with the rotating rod 13 to drive the movable rod 14 to move upward out of the inside of the round rod 6, thereby releasing the fixing effect on the round rod 6.

[0040] Then, the operator presses the circular plate 7 inwardly, so that the round rod 6 drives the squeezing plate 9 to move inwardly, thereby compressing the space inside the storage box 3, and then the pigment squeezing sealing plate 11 moves backward, and then the sealing plate 11 releases the sealing of the discharge port 5, so that the pigment can be squeezed out to the upper surface of the pigment tray 21 through the discharge port 5. When the pigment is extruded, the circular plate 7 can be loosened, so that the first spring 8 pushes the circular plate 7 to return to its original position under the action of elastic recovery, and then the round rod 6 drives the squeezing plate 9 to return to its original position. At this time, the second spring 10 will push the sealing plate 11 to return to its original position under the action of elastic recovery, so that the sealing plate 11 closes the discharge port 5, thereby avoiding pigment leakage and facilitating the use of the operator. Finally, the operator can move the movable plate 20 to move the pigment tray 21 and the pigment on the upper surface to a position that the child can touch for the child to use for color matching.
