The difference between this embodiment and the first embodiment is:

referring to fig. 2, 4 and 6, in the embodiment, an end of the first stopper 110 facing the second stopper 120 and an end of the second stopper 120 facing the first stopper 110 are disposed at an interval; the engaging assembly 300 further includes an isolating sleeve covering the outer surface of the second pre-opening engaging member 340 and/or the outer surface of the first pre-opening engaging member 320, wherein the isolating sleeve is used to limit the second pre-opening engaging member 340 from adhering to the surface of the first pre-opening engaging member 320 when the second pre-opening engaging member 340 and the first pre-opening engaging member 320 are oppositely disposed.

It should be noted that, when the end of the first stopper 110 facing the second stopper 120 and the end of the second stopper 120 facing the first stopper 110 are spaced apart, that is, when the end of the first support facing the second support and the end of the second support facing the first support are aligned but spaced apart, the embodiment arranges a spacer sleeve on the outer surface of the second pre-open engaging member 340 and/or on the outer surface of the first pre-open engaging member 320 (the spacer sleeve does not affect the magnetic attraction of the second pre-open engaging member 340 and/or the first pre-open engaging member 320), so that the spacer sleeve can be isolated between the second pre-open engaging member 340 and the first pre-open engaging member 320 when the second pre-open engaging member 340 and the first pre-open engaging member 320 are aligned and magnetically attracted, thereby preventing the lower surfaces of the second pre-open engaging member 340 and the first pre-open engaging member 320 from directly contacting each other under the action of the magnetic attraction, the situation that the second pre-opening suction element 340 and the first pre-opening suction element 320 cannot be separated can be avoided, and on the basis of the situation, the smoothness and the convenience of the box cover 200 in switching between the opening position and the covering position can be guaranteed on the basis that the state stability of the box cover 200 in the opening position is not affected.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.

Claims

1. A cartridge, comprising:

a box bottom;

2. The cassette of claim 1, wherein the second pre-open fastener is aligned and magnetically engaged with the first pre-open fastener when the free end is in the open position.

3. The case of claim 1, wherein the free end rotates less than 30 ° when rotated from the closed position to the pre-cover position; the free end rotates less than 30 ° when rotated from the pre-open position to the open position.

4. The cassette body of claim 1, wherein the second closure engaging member is provided in at least two numbers, and each of the second closure engaging members is provided on opposite sides of the second pre-open engaging member.

5. The box body according to claim 1, wherein the box bottom is provided with a receiving groove on a side surface thereof facing the rotating end, a first limiting block extending towards one side of the rotating end and a second limiting block symmetrical to the first limiting block are connected to a bottom of the receiving groove of the box bottom, and the first limiting block and the second limiting block are used together for limiting the second pre-opening suction assembly.

6. The box body according to claim 5, wherein one end of the first stopper facing the second stopper is connected to one end of the second stopper facing the first stopper.

7. The box body according to claim 5, wherein one end of the first stopper facing the second stopper is spaced apart from one end of the second stopper facing the first stopper;

8. An earphone charging box for receiving and charging earphones, comprising a box body according to any one of claims 1 to 7.

9. The charging box for earphones according to claim 8, wherein the box bottom is provided with a light hole on a side surface of the box bottom facing away from the rotation end, the charging box for earphones further comprises an indicator lamp aligned with the light hole, a controller electrically connected with the indicator lamp, and an inductor electrically connected with the controller and used for inducing whether the box cover is in the covering state, and the controller is used for controlling the indicator lamp to indicate the charging state of earphones when the inductor induces that the box cover is in the covering state.

10. The earphone charging box of claim 9, wherein the engaging assembly further comprises an indicating engaging member connected to the free end, the indicating engaging member being aligned with the sensor and generating a magnetic attraction force to the sensor when the lid is in the closed state.
