Among them, one end of the paper bin cover 1 is pivoted to the machine body and can be rotated to open or close the paper bin, and the locking buckle 5 is fixedly connected to the machine body. Specifically, the first connecting rod 3 and the second connecting rod 4 can also be arranged and hidden in the machine body.

[0026] The handle cover 2 can be driven to rotate relative to the paper bin cover 1 so that the handle cover 2 pushes the second connecting rod 4 to rotate through the sliding slot 41, thereby causing the other end of the second connecting rod 4 to be staggered with the locking buckle 5, thereby achieving unlocking, so that the paper bin cover 1 can be rotated to open the paper bin of the POS machine, so as to place the paper roll in the paper bin; the handle cover 2 can be driven to rotate in the opposite direction relative to the paper bin cover 1 so that the handle cover 2 pushes the second connecting rod 4 to rotate in the opposite direction through the sliding slot 41, thereby causing the other end of the second connecting rod 4 to be engaged with the locking buckle 5, thereby achieving self-locking, so that the paper bin cover 1 cannot rotate. Therefore, when tearing paper for the POS machine, the paper bin cover 1 will not rotate to open, thereby avoiding the problem of paper roll falling due to the opening of the paper bin cover 1 when tearing paper.

[0027] See also Figure 1 , Figure 4 and Figure 5In one embodiment, the buckle cover 2 includes a buckle portion 21 and a buckle portion 22, the buckle portion 21 is pivotally connected to the paper bin cover 1, one end of the buckle portion 22 is connected to one side of the buckle portion 21, and the other end of the buckle portion 22 can be slidably clamped in the sliding slot 41. It can be understood that the buckle portion 22 can be arranged on both sides of the buckle portion 21, and the first connecting rod 3, the second connecting rod 4, and the locking buckle 5 correspond one to one. Specifically, the buckle portion 21 and the buckle portion 22 are an integral connection structure, but not limited to this. For example, in other embodiments, the buckle portion 21 and the buckle portion 22 can also be a split connection structure. More specifically, a pin shaft 221 is convexly provided on the buckle portion 22, and the buckle portion 22 can be slidably clamped in the sliding slot 41 through the pin shaft 221, but not limited to this.

[0028] See also Figure 1 and Figure 3 In one embodiment, the paper bin cover 1 is provided with a through opening 11, and one end of the buckle portion 21 connected to the buckle portion 22 can pass through the opening 11. Further, the paper bin cover 1 is provided with a receiving groove 12 located on one side of the opening 11, and the buckle portion 21 is arranged in the receiving groove 12. Furthermore, the paper bin cover 1 is also provided with an operating groove 13 connected with the receiving groove 12, and the operating groove 13 is used for the operator to insert a finger into and move the buckle cover 2.

[0029] See also Figure 3 In one embodiment, the paper bin cover 1 includes a paper bin cover body 14, a paper bin cover outer body 15 and a paper bin cover connecting member 16. The paper bin cover outer body 15 is connected to the outer peripheral side of the paper bin cover body 14. The paper bin cover connecting member 16 is arranged at the bottom of the paper bin cover body 14. The opening 11 is arranged on the paper bin cover body 14 in a penetrating manner along the up and down direction. The accommodating groove 12 and the operating groove 13 are arranged on the top surface of the paper bin cover body 14. One end of the first connecting rod 3 is fixedly connected to the paper bin cover connecting member 16. However, the structure of the paper bin cover 1 is not limited thereto. For example, the paper bin cover 1 can adopt an integrally formed cover structure.

[0030] See also Figures 1 to 3 In one embodiment, the self-locking paper bin cover assembly 100 of the present invention further includes an elastic member 6, which is disposed between the paper bin cover 1 and the buckle cover 2; when the buckle cover 2 is driven to rotate and drive the second connecting rod 4 to rotate relative to the locking buckle 5, the buckle cover 2 squeezes the elastic member 6; when the buckle cover 2 is released, the buckle cover 2 rotates and resets under the elastic force of the elastic member 6, and drives the second connecting rod 4 to rotate and reset and engage with the locking buckle 5. Specifically, a positioning hole 17 is provided on the paper bin cover 1, and a positioning column 18 is provided in the positioning hole 17, and the elastic member 6 is disposed in the positioning hole 17 and sleeved on the positioning column 18, but the present invention is not limited thereto.

[0031] See also Figure 1 and Figure 5In one embodiment, the other end of the second connecting rod 4 is provided with a first arc-shaped matching portion 42, and the locking buckle 5 is provided with a second arc-shaped matching portion; when the buckle cover 2 rotates and drives the second connecting rod 4 to rotate, the first arc-shaped matching portion 42 and the second arc-shaped matching portion are engaged or staggered. Specifically, the first arc-shaped portion 42 is an outwardly convex arc-shaped matching structure, and the first arc-shaped portion 42 can be directly engaged or disengaged with the second arc-shaped matching portion of the locking buckle 5, and when engaged, the locking buckle 5 is located above the first arc-shaped matching portion 42, thereby limiting the movement of the second connecting rod 4, but not limited to this. For example, in some other embodiments, the first arc-shaped portion 42 and the second arc-shaped portion can be engaged and disengaged by using an outwardly convex arc-shaped matching structure, or the first arc-shaped portion 42 and the second arc-shaped portion can be engaged and disengaged by using a protrusion and groove matching structure. When the first arc-shaped matching part 42 is buckled with the second arc-shaped matching part, the self-locking paper bin cover assembly 100 of the present invention is in a self-locking state, and the second connecting rod 4 is restricted by the locking buckle 5 and cannot move up and down, so the paper bin cover 1 cannot rotate; when the first arc-shaped matching part 42 is mismatched with the second arc-shaped matching part, the self-locking paper bin cover assembly 100 of the present invention is in an unlocked state, and the paper bin cover 1 can rotate to open the paper bin of the POS machine. However, the buckling structure between the second connecting rod 4 and the locking buckle 5 is not limited to this.

[0032] Combination Figures 1 to 5 The specific working principle of the self-locking paper bin cover assembly 100 and the POS machine of the present invention is as follows:

[0033] When the POS machine needs to place a paper roll, the operator's finger can be inserted into the operating groove 13 and the buckle cover 2 can be moved to rotate the buckle cover 2 relative to the paper bin cover 1. The buckle cover 2 can then push the second connecting rod 4 to rotate through the sliding slot 41, so that the other end of the second connecting rod 4 is staggered with the locking buckle 5, thereby achieving unlocking and opening the paper bin cover 1 through the end of the paper bin cover 1 pivotally connected to the machine body. In this process, the buckle cover 2 squeezes the elastic member 6. Then the paper roll is placed in the paper bin of the machine body of the POS machine, and then the buckle cover 2 is released and the paper bin cover 1 is closed again. The buckle cover 2 rotates and resets under the elastic force of the elastic member 6, and drives the second connecting rod 4 to rotate and reset and engage with the locking buckle 5, thereby achieving self-locking, so that the paper bin cover 1 cannot rotate. During the use of the POS machine, the paper printed with charging information extends through the gap between the machine body and the other end of the paper bin cover 1. When tearing off the paper with charging information printed on it, the paper bin cover 1 is self-locked and cannot be rotated open, so the tearing operation will not cause the paper bin cover 1 to rotate open, thereby avoiding the problem of paper roll falling due to the opening of the paper bin cover 1 during tearing.

[0034] In summary, the self-locking paper bin cover assembly 100 of the present invention has a self-locking function, which can prevent the paper roll from falling due to the opening of the paper bin cover 1 when tearing paper, and has the characteristics of simple structure and simple operation.
