When the barrel cover rotates, the rotating shaft 5 is driven to rotate. A locking groove 201 is formed in one of the bases 2, a locking mechanism is arranged in the locking groove 201, and unlocking and locking are performed through a key. When the barrel body is in a normal placing state, the locking assembly is locked through a key, and the barrel cover cannot be opened; the locking structure is unlocked by using a key, and the barrel cover can be opened under the action of external force. The locking structure includes spacing cam 501, spacing post 4, arc board 7 and key seat 8, and spacing cam 501 is fixed with pivot 5, rotates together with pivot 5, and spacing post 4 sets up in spacing cam 501's top, carries on spacingly to spacing cam 501. Be equipped with chute 202 in the locking groove 201, the lower extreme c of chute 202 is close to the setting of spacing cam 501, and spacing post 4 slides and sets up in chute 202, and when spacing post 4 was in the lower extreme c of chute 202, with the contact of convex part b upper end of spacing cam 501, with spacing cam 501 suppression, spacing cam 501 can't rotate to carry out the locking to the bung. When the limiting column 4 is located at the upper end c' of the chute 202, the limiting column 4 is far away from the limiting cam 501, and the limiting cam 501 can rotate freely.

As shown in fig. 2 and 4, the arc plate 7 is disposed between the rotating shaft 5 and the limiting post 4, and one surface facing the rotating shaft 5 is an arc surface and can move between the limiting post 4 and the rotating shaft 5. One side of the arc plate 7 facing the limiting column 4 is provided with a concave part a and a convex part b, the concave part a is a concave arc surface, the convex part b is a convex arc surface, and the concave part a is connected with the convex part b. When the concave part a is positioned below the limiting column 4, the limiting column 4 is positioned at the lower end c of the chute 202; when the convex part b is positioned below the rotating shaft 5, the arc plate 7 contacts with the limit post 4 and jacks up the limit post 4, so that the limit post 4 is close to or positioned at the upper end c' of the inclined groove 202.

The key seat 8 is arranged below the arc plate 7 and is linked with the arc plate 7 through the connecting plate 9, a key is inserted into the key seat 8 and rotates, and the connecting plate 9 rotates along with the key, so that the arc plate 7 is driven to move. The other end of the arc plate 7 is in limit connection with the inner wall of the locking groove 201 through a spring 6.
