In the first stage of uncapping, the matching relationship between the rotating part 210 and the spring restraining assembly 300 is the transition process from fig. 5 to fig. 6, at this time, the first plane part 213 is separated from the outer side surface of the inner casing 310, the rotating abutting part 215 abuts against the outer side surface of the inner casing 310, along with the rotation of the cover body 200, the rotating abutting part 215 pushes the inner casing 310 to move towards the inside of the outer casing 320, the spring 330 is stressed and compressed, when the rotation angle of the cover body 200 reaches 45 °, the compression amount of the spring 330 is the largest, and at this time, the first stage of uncapping is finished. Next, when the cover 200 enters the second stage of opening the cover, the fit relationship between the rotating portion 210 and the spring constraining assembly 300 is the transition process from fig. 6 to fig. 7, at this time, the spring 330 will rebound from the contracted state, the resilience force pushes the inner shell 310 to move towards the outside of the outer shell 320, the inner shell 310 pushes the rotating abutting portion 215 to continue to rotate, the cover 200 automatically rotates to 90 ° in the direction away from the box 100, the second planar portion 214 abuts against the outer side surface of the inner shell 310, and at this time, the second stage of opening the cover is finished, and at this time, the cover 200 is completely.
When the cover 200 is closed, the movement process of the cover 200 can be divided into two stages, wherein the process that the cover 200 is rotated at an angle of 0-45 degrees from the vertical direction to the direction close to the box 100 is defined as the first stage of closing the cover, and the process that the cover 200 is rotated at an angle of 45-90 degrees to the direction close to the box 100 is defined as the second stage of closing the cover. In the first stage of closing the cover, the matching relationship between the rotating part 210 and the spring restraining assembly 300 is the transition process from fig. 7 to fig. 6, at this time, the second flat part 214 is separated from the outer side surface of the inner shell 310, the rotating abutting part 215 abuts against the outer side surface of the inner shell 310, the rotating abutting part 215 pushes the inner shell 310 to move towards the inside of the outer shell 320 along with the rotation of the cover body 200, the spring 330 is compressed under force, when the rotation angle of the cover body 200 reaches 45 °, the compression amount of the spring 330 is the maximum, and at this time, the first stage of closing the cover is finished. Next, when the cover 200 enters the second stage of closing the cover, the fit relationship between the rotating portion 210 and the spring constraining assembly 300 is the transition process from fig. 6 to fig. 5, at this time, the spring 330 will rebound from the contracted state, the resilience force pushes the inner shell 310 to move towards the outside of the outer shell 320, the inner shell 310 pushes the rotating abutting portion 215 to continue rotating, the cover 200 automatically rotates to 90 ° towards the direction close to the box 100, the first plane portion 213 abuts against the outer side surface of the inner shell 310, and at this time, the second stage of closing the cover is finished, and at this time, the cover 200 is completely closed.
Further, the rotation abutting portion 215 is preferably an arc structure, so that the cover 200 moves more smoothly during the rotation process.
The inner casing 310 is disposed inside the outer casing 320 and reciprocates along the inner sidewall of the outer casing 320, so that the inner casing 310 does not fall off during the reciprocating motion, and the structure is more reliable.
The outer housing 320 is fixedly coupled to the slot 110 by gluing, snapping, etc. such that the outer housing 320 is fixed to facilitate relative movement of the inner housing 310 with respect to the outer housing 320.
