Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 , the present invention provides a technical solution: a POS printer with a detachable paper bin, including: a main unit 1 and an interface 4. A control panel 2 is installed on the front of the main unit 1, a paper bin body 3 is arranged on the top of the main unit 1, and the interface 4 is opened on the side of the main unit 1;

[0023] A movable rod 5 penetrates through the top of the paper bin body 3. A clamping block 6 penetrating through the paper bin body 3 is installed on one side of the movable rod 5. A telescopic block 7 is installed on the side of the movable rod 5 away from the clamping block 6. A movable spring 8 is arranged between the telescopic block 7 and the groove of the paper bin body 3. A fixed block 9 is installed on the top of the movable rod 5. A clamping rod 10 penetrates through the middle of the fixed block 9. A return spring 11 is connected between the clamping rod 10 and the fixed block 9. A connecting block 12 is installed at the bottom of the clamping rod 10. The clamping block 6 is inserted into the inside of the main unit 1 through the groove.

[0024] During specific implementation, for the detachable paper cassette of the POS printer, when it is necessary to disassemble the paper cassette body 3, the latch rod 10 can be pulled upward to the top of the fixed block 9, causing the latch rod 10 to drive the connecting block 12 at the bottom to move upward and compressing the return spring 11. At this time, the connecting block 12 will move out of the groove of the paper cassette body 3, so that the connecting block 12 no longer blocks the movable rod 5 in the groove of the paper cassette body 3. Then, the movable spring 8 will drive the movable rod 5 to move to one side through the telescopic block 7, and the movable rod 5 will pull the latch 6 on one side into the groove of the paper cassette body 3. At this time, the latch 6 is no longer engaged with the groove of the host 1. Similarly, following the above steps, the other three groups of latch rods 10 are also moved upward. With the cooperation of the movable rod 5, the latch 6 also retracts into the paper cassette body 3, and without the latch 6 engaged with the groove of the host 1, the paper cassette body 3 can be quickly disassembled from the top of the host 1, thus facilitating the replacement of the paper cassette body 3 of different sizes to meet the usage requirements of different-sized papers;

[0025] Conversely, when installing the paper cassette body 3, only need to dock the paper cassette body 3 into the groove at the top of the host 1, and then push the movable rod 5 toward the side of the paper cassette body 3, causing the movable rod 5 to push the latch 6 on one side to move and engage the latch 6 with the groove of the host 1. At the same time, the movement of the movable rod 5 will stretch the movable spring 8 through the telescopic block 7. When the latch 6 is inserted into the groove of the host 1, the latch rod 10 can be released. At this time, the latch rod 10 will be reset under the action of the return spring 11, causing the latch rod 10 to drive the connecting block 12 at the bottom to move into the groove at the top of the paper cassette body 3, so that the connecting block 12 blocks the movable rod 5 in the groove at the top of the paper cassette body 3, preventing it from resetting and moving through the movable spring 8, thereby enabling the entire paper cassette body 3 to be more stably fixed on the top of the host 1, facilitating the quick installation and fixation of the paper cassette body 3.

[0026] Refer to Figure 1 、 Figure 2 and Figure 3 It can be seen that during use, the paper cassette body 3 can be disassembled from the top of the host 1 according to the usage requirements, then replace the paper cassette body 3 of different sizes, and fix the paper cassette body 3 on the top of the host 1 through the movable rod 5 and the latch 6, thus facilitating the quick replacement of the paper cassette body 3.

[0027] A limit block 13 is installed on the outer side of the interface 4. A pressure rod 14 penetrates through the top of the limit block 13. Both ends of the pressure rod 14 are connected with a connecting rod 15 through a rotating shaft. One side of the connecting rod 15 away from the pressure rod 14 is connected with a convex block 16 through a rotating shaft. A clamping block 17 is installed at the bottom of the convex block 16. A sliding block 18 is installed at the bottom of the clamping block 17. A smooth rod 19 is connected in the middle of the sliding block 18. A telescopic spring 20 is connected between the sliding block 18 and the smooth rod 19. Two groups of clamping blocks 17 are symmetrically installed about the center line of the limit block 13.

[0028] During specific implementation, for the detachable POS printer with a paper cartridge, when the power cord needs to be plugged into the interface 4, the pressure rod 14 can be pushed into the limit block 13, so that the pressure rod 14 exerts extrusion on the connecting rod 15. Since both ends of the pressure rod 14 are connected with the connecting rod 15 through a rotating shaft, and the other end of the connecting rod 15 is connected with the convex block 16 through a rotating shaft, and the convex block 16 is installed on the top of the clamping block 17, and the bottom of the clamping block 17 forms a sliding structure with the smooth rod 19 through the sliding block 18. Under the guiding action of the sliding block 18, when the pressure rod 14 extrudes the connecting rod 15, the connecting rod 15 will rotate through the rotating shaft. When the connecting rod 15 rotates, it will drive the clamping block 17 to slide along the smooth rod 19 through the convex block 16 and extrude the telescopic spring 20 sleeved outside the smooth rod 19, and at the same time make the two groups of clamping blocks 17 move away from each other;

[0029] Without the block of the clamping block 17, the power cord can be plugged into the interface 4, and then the pressure rod 14 is released, so that the pressure rod 14 does not exert extrusion on the connecting rod 15. At this time, the telescopic spring 20 will reset and push the sliding block 18 to slide reversely along the smooth rod 19, thereby driving the two groups of clamping blocks 17 to move towards each other. By the mutual approach movement of the two groups of clamping blocks 17, the power cord in the interface 4 can be clamped and limited, so as to avoid the loosening of the power cord.

[0030] Refer to Figure 1 And Figure 4 As can be seen, during use, in order to avoid the loosening of the power cord, the power cord can be passed through the limit block 13 and plugged into the interface 4, and then the telescopic spring 20 drives the two groups of clamping blocks 17 to move towards each other. At this time, the clamping block 17 can clamp and limit the power cord, so as to avoid the loosening of the power cord.

[0031] In summary: When the paper cassette detachable POS printer is in use, the paper cassette body 3 of different sizes can be installed on the top of the host 1 according to the printing requirements. The corresponding print head and roller inside the host 1 are matched with different paper widths, enabling the POS printer to adapt to print papers of different widths and different application environments. Then, the host 1 is charged through the interface 4. After the charging is completed, the host 1 can be started through the control panel 2 on the front of the host 1, enabling the host 1 to work properly, and the host 1 is controlled to perform printing work through the control panel 2. These are the usage characteristics of the paper cassette detachable POS printer.
