Circular Plastic Container Locking Structure

摘要

A circular plastic container locking mechanism includes a barrel body and a barrel cover; when the barrel body is stationary, the gear handle drives the gear to rotate towards a counter-clockwise direction, and with the rotating function of the gear, the rack on the barrel cover and the whole barrel cover are driven to move towards a clockwise direction, ten times the force for locking the barrel body and the barrel cover up and down can be produced with only a small amount of force by utilizing the lever effect of the gear handle and the effect of thread slope movement on the gear to lock the barrel cover and the barrel body; when the gear handle swings towards the clockwise direction, the barrel cover moves towards the counter-clockwise direction, and then the barrel cover is unlocked; and therefore locking and unlocking are very convenient.
