Fig. 1-7 are schematic structural views of the cartridge of this embodiment. As shown in fig. 1-7, the cartridge includes a first housing 1, a second housing 3, and a retraction assembly 6. Wherein, the first casing 1 and the second casing 3 are connected by a telescopic assembly 6 to be opened or closed, which is used for accommodating small articles such as earphones.

Wherein, the first shell 1 moves to the preset position of the second shell 3 by pressing and is closed with the second shell 3; then, the first housing 1 is rotated to snap the first housing 1 to a preset position of the second housing 3, that is, a snap position of the first housing 1 and the second housing 3, thereby locking the first housing 1 and the second housing 3. After the first shell 1 and the second shell 3 are locked, the first shell 1 and the second shell 3 can be prevented from being opened in the falling process, so that articles in the first shell 1 and the second shell 3 can be prevented from falling, losing or being damaged. In the process of pressing the first housing 1 and the second housing 3 to be closed, the first housing 1 presses the telescopic assembly 6. When the first housing 1 is rotated reversely so that the first housing 1 is separated from the buckling position of the second housing 3 and then unlocked, the telescopic assembly 6 is driven by reverse elasticity to drive the first housing 1 to be separated from the second housing 3, so that the first housing 1 and the second housing 3 are opened.

The first shell 1 and the second shell 3 of this embodiment are connected through the telescopic assembly 6 and the combination mode of the rotary buckle, so that the first shell 1 and the second shell 3 are connected together all the time in the processes of closing and opening, and the mode of the rotary buckle makes the first shell 1 and the second shell 3 open accidentally in the process of falling after the first shell 1 and the second shell are locked in a closed mode, so that the articles in the first shell can be prevented from falling and losing or being damaged.

Specifically, one end of the telescopic assembly 6 is connected to the first housing 1, and the other end of the telescopic assembly 6 is connected to the second housing 3, as shown in fig. 2 and 3.

One end of the elastic member 62 is connected to the second housing 3, and the other end of the elastic member 62 passes through the sleeve 63 and is connected to the end of the telescopic rod 61 close to the sleeve 63.

During the process of pressing the first housing 1, the first housing 1 moves into the sleeve 63 by pressing the telescopic rod 61, and when the first housing 1 is pressed to contact with the top end of the sleeve 63, the first housing 1 continues to press the sleeve 63 and the telescopic rod 61 to move towards the inside of the second housing 3. In this process, the telescopic rod 61 is always pressed against the elastic member 62. When the first casing 1 is moved to a predetermined position of the second casing 3, the pressing is stopped.

In this embodiment, the sum of the length of the sleeve 63 that can protrude from the second housing 3 and the length of the extension rod 61 that can protrude from the sleeve 63 determines the distance that the first housing 1 and the second housing 3 can be opened. Preferably, the sum of the lengths facilitates taking out or putting in the articles in the first and second housings 1 and 3 when they are opened. The elastic limit of the elastic member 62 may satisfy a maximum distance obtained when the first and second housings 1 and 3 are opened.

The telescopic assembly 6 of the present embodiment can still connect the first casing 1 and the second casing 3 together when the two casings are opened, so as to avoid losing one of the casings after the two casings are opened. Besides, the telescopic assembly 6 can be automatically opened through elasticity when the box body rotates to a preset position from the buckling position.

Further, the top opening of the sleeve 63 is smaller than the inner diameter of the sleeve 63, so that the sleeve 63 and its top opening form a step. The outer diameter of the telescopic rod 61 is smaller than or equal to the size of the top opening of the sleeve 63, the bottom of the telescopic rod 61 extends outwards along the circumferential direction to form a limiting edge, the circumferential size of the limiting edge is larger than the size of the top opening of the sleeve 63 and smaller than or equal to the inner diameter of the sleeve 63, so that the telescopic rod 61 can extend out of the top opening of the sleeve 63, the limiting edge at the bottom of the telescopic rod 61 is connected with the top of the sleeve 63, the telescopic rod 61 can be prevented from being separated from the sleeve 63, and the telescopic rod 61 can reach the maximum extending amount. The sleeve 63 can be designed to be flush with the plane of the outside of the connecting cavity 7 or higher than the plane of the outside of the connecting cavity 7 according to the length requirement of the telescopic rod 61. Preferably, the height of said sleeve 63 is flush with the height of the connection chamber 7 when the box is closed.

The top of the telescopic rod 61 is fixedly connected with the first casing 1. When the first housing 1 rotates from the predetermined position of the second housing 3 to the fastening position of the second housing 3 or rotates in the opposite direction, the first housing 1 can drive the telescopic rod 61 to rotate synchronously.

In this embodiment, the top of the inner side of the first casing 1 is provided with a connecting column downward, as shown in fig. 3. The spliced pole has the screw hole, and the top outside of telescopic link 61 is provided with the external screw thread, and telescopic link 61 passes through screw thread fixed connection with first casing 1, is convenient for install and dismantle. When first casing 1 and second casing 3 were closed, there was the clearance all between the bottom surface of spliced pole to the outside top surface of connecting cavity 7 and the outside top surface of sleeve 63, can avoid the unable buckle locking of first casing 1 and second casing 3.

The box also includes an inner liner 12, as shown in fig. 2 and 3. The inner liner 12 is disposed inside the first housing 11, and the inner liner 12 can expose the connection column to facilitate connection with the extension rod 61. The liner 12 is resilient and serves to secure and protect the contents of the case when the case is closed. When the earphone is in the case, the inner liner 12 can fix the charging position of the earphone in the case and protect the appearance of the earphone. Preferably, the inner liner 12 is made of silicone, foam, sponge or silicone-like material.

One of the first shell 1 and the second shell 3 is provided with a clamping block 2, and the other one is provided with a clamping groove 5 matched with the clamping block 2. When the first housing 1 is pressed to a predetermined position of the second housing 3, the first housing 1 is rotated so that the latch 2 is rotated into the latch groove 5, thereby locking the two. When unlocking, the first housing 1 is rotated in the reverse direction. Preferably, the first housing 1 and the second housing 3 are provided with at least two clamping blocks 2 and clamping grooves 5. Each group of clamping blocks 2 and the clamping grooves 5 are distributed along the circumference of the corresponding shell at equal angles respectively, so that one side of each shell can be prevented from being opened, and articles can be prevented from falling off.

In the present embodiment, the latch 2 is disposed on the inner circumferential surface of the first housing 1 and extends in the circumferential direction, as shown in fig. 5.
