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.

[0025] Please refer to Figure 1-7, the present utility model provides a technical solution: A coating machine turnover frame that is convenient for disassembly and assembly includes two fixed rods 2. There are two connecting rods 4 provided between the two fixed rods 2. A connecting mechanism 3 is provided inside the connecting rod 4. The connecting mechanism 3 includes two screw rods 8, a rotating cylinder 9, two rectangular blocks 5, two rotating blocks 11 and two hexagonal blocks 12. A control mechanism 15 is provided inside the rotating block 11. The control mechanism 15 includes a moving rod 16, a plurality of pull ropes 17 and a pressing rod 18. One end of the fixed rod 2 away from the connecting rod 4 is fixed with a rotating shaft 1. Both the rotating cylinder 9 and the screw rod 8 are located inside the connecting rod 4. The rotating cylinder 9 is rotatably connected to the connecting rod 4. The screw rod 8 is screwed to the connecting rod 4. Two retaining grooves 7 are opened on the outer side wall of the screw rod 8. Two retaining strips 10 are fixed to the inner side wall of the rotating cylinder 9. The screw rod 8 is located inside the rotating cylinder 9. The retaining strip 10 is located inside the retaining groove 7. One end of the screw rod 8 away from the rotating cylinder 9 is fixedly connected to the rectangular block 5. Card holes 6 are opened on the upper, lower, front and rear sides of the rectangular block 5. The rotating block 11 is located inside the fixed rod 2. The rotating block 11 is rotatably connected to the fixed rod 2. One end of the rotating block 11 close to the connecting rod 4 is provided with an insertion hole 26. A plurality of storage holes 24 are opened on the inner side wall of the insertion hole 26. A pushing spring 22 is fixed inside the storage hole 24. The other end of the pushing spring 22 is fixed with a clamping block 21. One end of the rotating block 11 away from the insertion hole 26 is fixedly connected to the hexagonal block 12. A rotating rod 13 is rotatably connected inside the fixed rod 2. The rotating rod 13 and the rotating block 11 are driven by bevel gears 14. Insert the rectangular block 5 into the insertion hole 26, and the clamping block 21 is inserted into the card hole 6. Then rotate the hexagonal block 12. The hexagonal block 12 drives the rotating block 11 to rotate. The rotating block 11 drives the rectangular block 5 and the screw rod 8 to rotate. The screw rod 8 drives the rotating cylinder 9 to rotate through the retaining groove 7 and the retaining strip 10. The rotating cylinder 9 drives the other screw rod 8 to rotate. And the rotating block 11 drives the rotating rod 13 and the other rotating block 11 to rotate through the bevel gear 14. The other rotating block 11 drives the other two screw rods 8 to rotate through transmission. In this way, the four screw rods 8 rotate simultaneously into the inside of the connecting rod 4, connecting the connecting rod 4 and the fixed rod 2 together to form a turnover frame body. In this way, the installation and composition are convenient.

[0026] Furthermore, a circular groove 20 is formed at one end of the rotating block 11 away from the connecting rod 4. The moving rod 16 is located inside the hexagonal block 12, and the pressing rod 18 is located inside the circular groove 20. The pressing rod 18 and the moving rod 16 are rotatably connected. The outer side wall of the pulling rope 17 is fixedly connected to the pressing rod 18. The other end of the pulling rope 17 is fixedly connected to one end of the clamping block 21 close to the pushing spring 22. A connecting spring 19 is fixed inside the circular groove 20, and the other end of the connecting spring 19 is fixedly connected to the pressing rod 18. Two stoppers 23 are fixed inside the circular groove 20. Two C-shaped grooves 25 are formed on the outer side wall of the moving rod 16. When the moving rod 16 is pressed, the moving rod 16 drives the pressing rod 18 to move. The pressing rod 18 pulls the pulling rope 17, and the pulling rope 17 pulls the clamping block 21. The clamping block 21 moves out of the clamping hole 6. At the same time, the stopper 23 enters the inside of the C-shaped groove 25. Then the moving rod 16 is rotated to make the stopper 23 snap into the other end of the C-shaped groove 25, so that the rotating block 11 can be separated from the rectangular block 5, which is convenient for disassembly.

[0027] During operation, the rectangular block 5 is inserted into the insertion hole 26, and the clamping block 21 is snapped into the clamping hole 6. Then the hexagonal block 12 is rotated. The hexagonal block 12 drives the rotating block 11 to rotate. The rotating block 11 drives the rectangular block 5 and the screw rod 8 to rotate. The screw rod 8 drives the rotating cylinder 9 to rotate through the retaining groove 7 and the retaining strip 10. The rotating cylinder 9 drives another screw rod 8 to rotate. And the rotating block 11 drives the rotating rod 13 and another rotating block 11 to rotate through the bevel gear 14. Another rotating block 11 drives another two screw rods 8 to rotate through transmission, so that the four screw rods 8 rotate simultaneously into the inside of the connecting rod 4, connecting the connecting rod 4 and the fixed rod 2 together to form a flipping frame body, which is convenient for installation and assembly. When the moving rod 16 is pressed, the moving rod 16 drives the pressing rod 18 to move. The pressing rod 18 pulls the pulling rope 17, and the pulling rope 17 pulls the clamping block 21. The clamping block 21 moves out of the clamping hole 6. At the same time, the stopper 23 enters the inside of the C-shaped groove 25. Then the moving rod 16 is rotated to make the stopper 23 snap into the other end of the C-shaped groove 25, so that the rotating block 11 can be separated from the rectangular block 5, which is convenient for disassembly.
