DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 6 As shown, the milk powder cover of the present invention comprises an upper cover 1, a lower cover 2 and an anti-theft structure, the rear side of the upper cover 1 is connected to the rear side of the lower cover 2 by a hinge, a first vertically arranged installation guide groove 11 and a vertically arranged connecting hook 12 are provided on the side wall of the upper cover 1, the anti-theft structure comprises an anti-theft buckle piece 31 and at least one connecting rib 32, the anti-theft buckle piece 31 is easily disconnected from the side wall of the first installation guide groove 11 through the connecting rib 32, and the anti-theft buckle piece 31 can move downward along the first installation guide groove 11, and connecting shafts 33 are respectively provided on both sides of the lower part of the anti-theft buckle piece 31;

[0025] Two rotating shaft buckles 21 and connecting buckles 22 are arranged on the side wall of the lower cover 2, the connecting hook 12 is matched and snapped into the connecting buckle 22, and the anti-theft buckle piece 31 is arranged at the front side of the connecting hook 12. When the anti-theft buckle piece 31 moves downward along the first installation guide groove 11, the two connecting rotating shafts 33 can be snapped into the two rotating shaft buckles 21 respectively, and the anti-theft buckle piece 31 can rotate inward around the connecting rotating shaft 33 to push the connecting hook 12 out of the connecting buckle 22;

[0026] At least one opening spring piece 4 is arranged between the upper cover 1 and the lower cover 2. When the milk powder cover is not opened, the opening spring piece 4 is in a compressed state.

[0027] When the milk powder cover of the present invention is opened, the user presses the anti-theft buckle piece 31 to move the anti-theft buckle piece 31 downward along the first installation guide groove 11 until the two connecting shafts 23 are respectively inserted into the two shaft buckle positions 21, and then the user pushes the upper half of the anti-theft buckle piece 31 inward to rotate the anti-theft buckle piece 31 inward around the connecting shaft 23. The anti-theft buckle piece 31 acts on the connecting hook 12 to move the connecting hook 12 inward and be pushed out to the outside of the connecting buckle position 22. The connecting hook 12 is separated from the connecting buckle position 22, so that the milk powder cover can be opened. When the anti-theft buckle 31 moves downward along the first installation guide groove 11, the anti-theft buckle 31 and the upper cover 1 will be disconnected and will not be restored, thereby achieving an anti-theft effect, and the anti-theft buckle 31 will remain in the lower cover 2, that is, the anti-theft buckle 31 will not be torn off, and the anti-theft buckle 31 will not be separated from the milk powder cover, thereby effectively reducing the possibility of causing plastic pollution, and at least one opening spring 4 is arranged between the upper cover 1 and the lower cover 2, and when the milk powder cover is not opened, the opening spring 4 is in a compressed state. When the connecting hook 12 is pushed out to the outside of the connecting buckle position 22, under the action of the elastic force of the opening spring, the upper cover 1 is bounced upward to open the milk powder cover, which is convenient for opening the milk powder cover and more convenient to use.

[0028] Specifically, in order to make the milk powder cover more convenient to use, Figure 1 , Figure 2 As shown, the first installation guide groove 11 and the connection hook 12 are both arranged on the front side of the upper cover 1, and the shaft buckle position 21 and the connection buckle position 22 are both arranged on the front side of the lower cover 2. In this way, the front sides of the upper cover 1 and the lower cover 2 are detachably connected together through the connection hook 12 and the connection buckle position 22 to form a buckle structure, and the rear sides of the upper cover 1 and the lower cover 2 are connected by a hinge, and the anti-theft buckle piece 31 is also located on the front sides of the upper cover 1 and the lower cover 2, which is convenient for use.

[0029] In order to improve the use effect of the opening spring piece 4 , the opening spring piece 4 is connected and arranged inside the upper cover 1 , and the opening spring piece 4 is located at the rear side of the upper cover 1 .

In order to improve the use effect of pressing the anti-theft buckle piece 31, a preferred structure of pressing the anti-theft buckle piece 31 of the present invention is: Figure 2 , Figure 5 and Figure 6 As shown, the anti-theft buckle plate 31 includes a horizontal plate portion 311 and a vertical plate portion 312 connected together, the vertical plate portion 312 is located on the outside of the horizontal plate portion 311, and the connection between the horizontal plate portion 311 and the vertical plate portion 312 is connected by an arc transition, and the connecting shaft 33 is arranged at the lower part of the vertical plate portion 31.

[0031] In order to reduce the possibility of deviation when the anti-theft buckle piece 31 is pressed downward, it is ensured that the connecting shaft 23 can be inserted into the shaft buckle position 21. Figure 3 , Figure 4 As shown, a second installation guide groove 23 is provided on the side wall of the lower cover 2, and the second installation guide groove 23 corresponds to the first installation guide groove 11 in the upper and lower positions, and the rotating shaft buckle positions 21 are respectively provided on the left and right side walls of the second installation guide groove 23. When the anti-theft buckle piece 31 is pressed and moved downward, it will also be stuck in the second installation guide groove 23, and the second installation guide groove 23 plays a role of guiding and positioning.

[0032] In order to make it more convenient for users to use and understand whether the milk powder cover has been opened, Figure 4 As shown, the bottom surface of the second installation guide groove 23 is provided with an unopened identification structure 24. The unopened identification structure 24 can be text or a pattern, such as Figure 4 Furthermore, a push-to-open identification structure 34 is provided on the upper surface of the horizontal plate portion 311, and the push-to-open identification structure 34 prompts the user to press the anti-theft buckle 31 to open the milk powder cover. The push-to-open identification structure 34 can be text or a pattern, and the text includes English.

[0033] In order to reduce the possibility of mosquitoes and other insects entering the milk powder cap, Figure 3 As shown, a circle of mounting grooves 25 are arranged on the side wall of the lower cover 2 , and the lower surface of the upper cover 1 is arranged in the mounting grooves 25 .
