A plurality of reinforcing ribs 12 are fixedly provided on the top of the top cover 9. The provision of the reinforcing ribs 12 can improve the bearing performance of the top cover 9 and prevent the top cover 9 from deformation. The provision of the reinforcing ring 3 can improve the overall strength of the zinc cylinder 1 and prevent the zinc cylinder 1 from deformation and damage.

[0028] Reference Figures 2 to 4 In order to improve the firmness of the top cover 9, two clamping blocks 13 are fixedly provided on the outer wall of the top cover 9, and the clamping groove 4 is in an "L" shape. The clamping block 13 and the clamping groove 4 are matched. Two mounting holes 14 are provided on the outer wall of the top cover 9, and a spring 15 is fixedly provided on the inner wall of the mounting hole 14. A push rod 16 is fixedly provided at one end of the spring 15. The end of the push rod 16 away from the spring 15 is in an arc shape, and one end of the push rod 16 in an arc shape is matched with the first arc groove 5, the second arc groove 6, and the positioning hole 7. The coordinated use of the clamping block 13, the clamping groove 4, the push rod 16 and the positioning hole 7 can realize the locking of the top cover 9. Compared with the traditional sealing agent packaging method, the fixing effect can be improved, and the top cover 9 can be effectively prevented from jumping out and injuring people.

[0029] Working principle: During assembly, first squeeze the two push rods 16 inward, the push rod 16 squeezes the spring 15 on one side, and then insert the two clamping blocks 13 into the card slot 4. At this time, one end of the push rod 16 fits with the inner wall of the first arc-shaped groove 5, and then press the top cover 9 downward. When the clamping block 13 fits with the bottom inner wall of the card slot 4, it cannot be pressed down further. At this time, the arc end of the push rod 16 fits with the inner wall of the second arc-shaped groove 6, and then the reinforcing rib 12 is buckled to rotate the top cover 9 clockwise. The top cover 9 drives the clamping block 13 and the push rod 16 to move. The clamping block 13 is clamped in the card slot 4 to realize the positioning of the top cover 9. When the clamping block 13 fits with the inner wall of one side of the card slot 4 and cannot move, the push rod 16 moves to the position of the positioning hole 7. The spring 15 pushes out the push rod 16, and the push rod 16 is inserted into the positioning hole 7 to reinforce the top cover 9, and then the sealing agent is squeezed into the first arc groove 5 and the card groove 4. The sealing agent will flow into the card groove 4, the second arc groove 6 and the first arc groove 5, and fill their space to achieve the purpose of sealing. The coordinated use of the card block 13, the card groove 4, the push rod 16 and the positioning hole 7 can realize the locking of the top cover 9. Compared with the traditional sealing agent packaging method, it can improve the fixing effect and effectively prevent the top cover 9 from jumping out and injuring people. The setting of the reinforcing rib 12 can improve the bearing performance of the top cover 9 and prevent the top cover 9 from deformation. The setting of the reinforcing ring 3 can improve the overall strength of the zinc cylinder 1 and prevent the zinc cylinder 1 from deformation and damage.
