Detailed implementation manners

[0043] Next, in combination with the specific implementation manners of the present invention, the technical solutions in the present invention will be clearly and completely described. Obviously, the described implementation manners are only a part of the implementation manners of the present invention, rather than all of the implementation manners. Based on the implementation manners in the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0044] As Figures 1-4 shown, a cartridge fixing bracket structure for a portable printer according to the present invention includes a cartridge fixing cover 1, a cartridge fixing bracket 2, a rotating shaft 3, and a probe board 4.

[0045] Among them, as Figure 2 shown, the cartridge fixing cover 1 is hinged to the top of the cartridge fixing bracket 2, and the cartridge fixing cover 1 and the cartridge fixing bracket 2 are used to fix the cartridge 5; specifically, the cartridge fixing bracket 2 is used to be fixed in the ink cartridge of the printer. When the cartridge 5 needs to be replaced, as Figure 1 shown, the cartridge fixing cover 1 is flipped upward to open it, and then the cartridge 5 is taken out from the cartridge fixing bracket 2. After replacing the new cartridge 5, as Figure 2 shown, the cartridge fixing cover 1 is flipped downward to close it on the top of the cartridge fixing bracket 2.

[0046] In the above structure, an accommodation cavity 203 is provided inside the ink cartridge fixing bracket 2, and the ink cartridge 5 is placed in the accommodation cavity 203. The shape of the accommodation cavity 203 matches the shape of the ink cartridge 5. Figure 2 The shape of the ink cartridge 5 shown in Figure 2 is L-shaped.

[0047] As Figure 1 shown, a rotating shaft 3 is fixed on each side of the ink cartridge fixing bracket 2. Among them, the rotating shaft 3 horizontally penetrates through the ink cartridge fixing cover 1 and is rotatably connected. When the ink cartridge fixing cover 1 is opened, the rear end of the ink cartridge fixing cover 1 rotates on the rotating shaft 3. When the ink cartridge fixing cover 1 is opened, the accommodation cavity 203 is exposed to facilitate the installation of the ink cartridge 5.

[0048] As Figure 1 shown, the probe board 4 is fixed to the rear end of the ink cartridge fixing bracket 2. Specifically, as Figure 3 shown, a number of probe parts 401 are fixed on the probe board 4. The probe parts 401 penetrate forward through the rear end of the ink cartridge fixing bracket 2 and abut against the rear end of the ink cartridge 5. Among them, when the ink cartridge 5 is correctly installed, the probe parts 401 will contact the metal contact pads on the ink cartridge 5, thereby establishing an electrical connection.

[0049] In the above ink cartridge fixing bracket structure, the ink cartridge fixing cover 1 includes an elastic pressing plate 11, a V-shaped elastic piece 12, a rectangular elastic piece 13, a front baffle 14 and a rear baffle 15.

[0050] Among them, as Figure 2 shown, the elastic pressing plate 11 is hinged to the ink cartridge fixing bracket 2 and presses on the top of the ink cartridge 5. One V-shaped elastic piece 12 is provided on each side of the elastic pressing plate 11; as Figure 1 shown, one end of the V-shaped elastic piece 12 is fixed to the elastic pressing plate 11, and the other end is horizontally bent outward from the elastic pressing plate 11 to form a pressing part 1201. The pressing part 1201 is used for finger pressing to make the V-shaped elastic piece 12 deflect. A first limiting protrusion 1202 is provided below the pressing part 1201. The first limiting protrusion 1202 is provided on the outer surface of the V-shaped elastic piece 12; a buckle groove 201 is provided on the side of the ink cartridge fixing bracket 2 and corresponding to the position of the V-shaped elastic piece 12. A second limiting protrusion 202 is provided on the groove wall of the buckle groove 201 and corresponding to the position of the first limiting protrusion 1202; the V-shaped elastic piece 12 elastically abuts in the corresponding buckle groove 201, so that the top of the first limiting protrusion 1202 abuts against the bottom of the second limiting protrusion 202 at the corresponding position.

[0051] When it is necessary to open the ink cartridge fixing cover 1, pinch the pressing parts 1201 on both sides of the elastic pressing plate 11 inward with fingers, so that the inner width of the V-shaped elastic piece 12 becomes narrower. During this process, the V-shaped elastic piece 12 drives the first limit protrusion 1202 to move away from the bottom of the second limit protrusion 202, completing the unlocking of the first limit protrusion 1202 and the second limit protrusion 202. Then, flip the elastic pressing plate 11 to open it. During this process, the V-shaped elastic piece 12 moves out of the buckle groove 201.

[0052] In the above structure, the first limit protrusion 1202 and the second limit protrusion 202 adopt a snap-lock structure to achieve automatic locking. Specifically, as Figure 1 shown, the opposite ends of the first limit protrusion 1202 and the second limit protrusion 202 in the up and down direction are both wedge-shaped, and the opposite ends of the first limit protrusion 1202 and the second limit protrusion 202 in the up and down direction are both rectangular; when it is necessary to close the ink cartridge fixing cover 1, flip the elastic pressing plate 11 downward so that the V-shaped elastic piece 12 is inserted into the corresponding buckle groove 201, and then press the V-shaped elastic piece 12 so that the first limit protrusion 1202 touches the second limit protrusion 202 downward. During this process, the wedge-shaped surface at the upper end of the second limit protrusion 202 touches and slides with the wedge-shaped surface at the lower end of the first limit protrusion 1202. The second limit protrusion 202 forces the first limit protrusion 1202 to change its position inward, thereby causing the V-shaped elastic piece 12 to flex and deform to store energy. When the first limit protrusion 1202 passes over the second limit protrusion 202, the V-shaped elastic piece 12 rebounds, pushing the first limit protrusion 1202 to move to the bottom of the second limit protrusion 202 and form a holding state, completing the locking of the first limit protrusion 1202 and the second limit protrusion 202. In this state, the ink cartridge fixing cover 1 is firmly buckled on the ink cartridge fixing bracket 2.

[0053] To increase the speed when opening the ink cartridge fixing cover 1 and facilitate the opening operation, the above ink cartridge fixing cover 1 further includes a rectangular elastic piece 13. Among them, a square hole 1101 is vertically and penetratingly provided on the elastic pressing plate 11; one end of the rectangular elastic piece 13 is fixedly connected to the hole wall of the square hole 1101, and the other end elastically abuts against the top of the ink cartridge 5; when the first limit protrusion 1202 and the second limit protrusion 202 are locked, the rectangular elastic piece 13 abuts against the ink cartridge 5 to store energy. When the first limit protrusion 1202 and the second limit protrusion 202 are unlocked, the rectangular elastic piece 13 rebounds, pushing the ink cartridge fixing cover 1 to pop open. Further, to improve the abutting effect, a third limit protrusion 1301 is provided at the bottom of one end of the rectangular elastic piece 13, and the third limit protrusion 1301 abuts against the top of the ink cartridge 5. Through the third limit protrusion 1301, the deformation amplitude of the rectangular elastic piece 13 can be increased, thereby improving the effect of elastic abutment.

[0054] In the above structure, the thickness of the rectangular spring piece 13 is less than or equal to the depth of the square hole 1101. The rectangular spring piece 13 acts as a supporting force to make the ink cartridge 5 more firmly fixed. When the printer is printing, the ink cartridge 5 has better stability and is not easy to loosen and leak ink.

[0055] like Figure 3 and 4 As shown, a front baffle 14 is fixed at each of the two sides of the front end of the elastic pressure plate 11. When the ink cartridge 5 is fixed, the front end of the ink cartridge 5 is sleeved between the two front baffles 14. The front baffles 14 protect both sides of the front end of the ink cartridge 5, thereby improving the stability of the ink cartridge 5 after installation.

[0056] A rear baffle 15 is fixed at each of the two sides of the rear end of the elastic pressure plate 11, and the rotating shaft 3 horizontally passes through the rear baffle 15 at the corresponding position and is rotatably connected. When the ink cartridge 5 is fixed, the rear end of the ink cartridge 5 is sleeved between the two rear baffles 15, and the rear baffle 15 is used to protect the two sides of the rear end of the ink cartridge 5, thereby improving the stability of the ink cartridge 5 after installation.

[0057] The method of using the ink cartridge fixing bracket structure for a portable printer of the utility model is as follows:

[0058] When the ink cartridge fixing cover 1 needs to be opened, the pressing parts 1201 on both sides of the elastic pressure plate 11 are pinched inward by fingers to unlock the first limiting protrusion 1202 from the second limiting protrusion 202. After unlocking, the rectangular spring piece 13 pushes the ink cartridge fixing cover 1 to eject and open. During the process, the ink cartridge fixing cover 1 is flipped over with the assistance of manual labor to improve the opening efficiency of the ink cartridge fixing cover 1.

[0059] When the ink cartridge fixing cover 1 needs to be closed, the elastic pressure plate 11 is flipped downward to insert the V-shaped spring piece 12 into the corresponding snap groove 201, and then the V-shaped spring piece 12 is pressed to make the first limiting protrusion 1202 pass downward over the second limiting protrusion 202. After that, under the elastic force of the V-shaped spring piece 12, the first limiting protrusion 1202 moves to the bottom of the second limiting protrusion 202 and forms a state of upper and lower abutment. In this state, the ink cartridge fixing cover 1 is firmly buckled on the ink cartridge fixing bracket 2.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
