Detailed Description

The present invention will be described in further detail with reference to the following examples and accompanying drawings.

Referring to fig. 1, 2, 3, 4 and 5, a first embodiment of the cylinder can cover structure with a safety lock of the present invention is shown. Comprises a cylinder cover 1, a cylinder body 3 and a plastic cylinder connecting piece 2 fixed on the mouth of the cylinder body 3. The connecting piece 2 is provided with a cylindrical skirt body 21, an annular baffle plate 22 extends out of the top of the connecting piece 2 along the outer circumferential wall, a blocking piece 23 is arranged on the outer circumferential wall of the cylindrical skirt body 21 of the connecting piece 2, the blocking piece 23 is positioned below the annular baffle plate 22, and a fixing groove 24 is formed between the annular baffle plate 22 and the blocking piece 23. The top of the cylindrical can body 3 is provided with a rim rib 31 formed by inward rolling edges, and the rim rib 31 can be clamped in the fixing groove 24 between the annular baffle plate 22 and the blocking plate 23 on the connecting piece 2, so that the connecting piece 2 can be fixedly clamped at the can opening of the can body 3. An extension part 211 is arranged at a proper position of the cylindrical skirt body 21 of the connecting piece 2, a strip-shaped hole 2111 is arranged on the extension part 211 to enclose a spring plate 2112 with a specific shape, namely, the extension part 211 is divided into the spring plate 2112 through the strip-shaped hole 2111, the spring plate 2112 is provided with a spring plate root 2113 to be connected with the extension part 211, and a locking column 2114 and a pressing column 2115 are fixedly arranged on the spring plate 2112 in a protruding way; the pressing post 2115 is located at one end close to the root 2113 of the spring plate, the locking post 2114 is located at one end far from the root 2113 of the spring plate, and the end of the locking post 2114 is provided with a bevel 2116. The cylindrical can body 3 is further provided with a can body locking hole 32 and a can body pressing hole 33, the locking column 2114 can pass through the can body locking hole 32, and the pressing column 2115 can pass through the can body pressing hole 33 and extend out of the cylindrical can body 3. The cylindrical can lid 1 has a first can lid skirt 11, the first can lid skirt 11 is cylindrical and can be connected to the outer wall of the can opening of the cylindrical can body 3, that is, the cylindrical can lid 1 can be inserted into the cylindrical can body 3, the first can lid skirt 11 is provided with a can lid locking hole 111, and the locking post 2114 can pass through the can lid locking hole 111. Thus, when the can cover 1 is buckled on the can body 3, the can cover 1 is pressed downwards, the locking columns 2114 can be bounced into the can cover locking holes 111 when the can cover 1 is in place, and at the moment, the can cover 1 and the can body 3 are locked together, so that the can cover 1 cannot be opened. When the pressing post 2115 is pressed by hand, the connecting piece 2 is made of plastic material and has certain elasticity, the elastic piece 2112 swings inwards by taking the root 2113 of the elastic piece as a base, and at the moment, the can cover 1 can be pulled out, so that the can cover 1 is separated from the can body 2, and the can cover 1 can be opened.

Preferably, in the cylinder cap structure with the safety lock, the elastic piece 2112 includes a first elastic piece 2112A and a second elastic piece 2112B, and the first elastic piece 2112A and the second elastic piece 2112B adopt mirror surfaces180 ⁰ The relative positions are arranged, and when the can is opened, the two elastic sheets can be pressed and the can body can be held tightly by only one hand. Thus, the structure is more reasonable, and the use is more convenient.

Fig. 6 shows a second embodiment of the cylindrical can lid structure with a safety lock according to the present invention.
