Description

Technical Field

[0001] The utility model belongs to the technical field of printer manufacturing and maintenance, and particularly relates to a simple reset device for an ink cartridge chip. Background Art

[0002] With the rapid development of modern office and printing technologies, laser printers and inkjet printers have become indispensable devices in people's daily work. As an important component of a printer, the cost of an ink cartridge accounts for a large part of the overall cost of the printer.

[0003] As a key component of the ink cartridge, the ink cartridge chip stores information such as ink capacity and printed ink volume, which directly affects the service life and printing effect of the ink cartridge.

[0004] However, during the use of existing ink cartridge chips, problems such as chip damage and unrecognizability often occur due to exhausted ink or excessive printing times, which requires users to frequently replace the ink cartridge, increasing the usage cost.

[0005] To address this issue, some ink cartridge chip resetters have emerged on the market. By using an ink cartridge chip resetter, the information stored in the ink cartridge chip can be reset to meet the usage requirements of the ink cartridge.

[0006] However, since the striker in contact with the chip of this ink cartridge chip resetter is exposed for a long time, the striker will be oxidized, worn, or even broken, thus affecting the normal operation of the resetter. Summary of the Utility Model

[0007] The utility model proposes the following technical solutions for the problem that in the prior art, the striker in contact with the chip of an ink cartridge chip resetter is exposed for a long time, which may cause the striker to be oxidized, worn, or even broken, thus affecting the normal operation of the resetter:

[0009] Preferably, a convex block is fixedly connected to the top of the housing.

[0010] As an optimization of the above technical solution, a striker tube is fixedly connected to the top of the support plate at the position of the striker, and the inner diameter of the striker tube is the same as the outer diameter of the striker.

[0011] As an optimization of the above technical solution, one end of the bidirectional screw rod away from the moving gear is connected with a bearing by interference fit, and the bearing is fixedly connected inside the housing.

[0012] As an optimization of the above technical solution, the two bidirectional screw rods have opposite thread directions.

[0013] As an optimization of the above technical solution, the retractable support frame is composed of two X-folded rods and connecting blocks. The connecting blocks are fixedly installed at the four support corners of the X-folded rods. The connecting blocks and the screw nuts are rotationally connected by round rods, and the top of the connecting blocks and the bottom of the support plate are rotationally connected by round rods.

[0014] The beneficial effects of the present utility model are as follows:

[0015] (1) A retractable support frame is added at the position where the striker is connected inside the resetter.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] Embodiment 1

[0023] The utility model provides a simple reset device for a cartridge chip. As Figures 1 - 4 shown, it includes: a housing 1. One end face of the housing 1 is rotatably connected with a rotating shaft 6. One end face of the rotating shaft 6 is fixedly connected with a rotating button 5. One end face of the rotating shaft 6 opposite to the rotating button 5 is fixedly connected with a moving gear 7. Two static gears 11 are rotatably connected to one end face inside the housing 1 and are meshed with the moving gear 7 through tooth patterns. One end face of each static gear 11 is fixedly connected with a bidirectional screw rod 9. Two screw nuts 12 are symmetrically connected to the outer surface of the bidirectional screw rod 9 through threads. The top end of the screw nut 12 is movably connected with a retractable support frame 13. The top end of the retractable support frame 13 is movably connected with a support plate 10. A striker 2 is fixedly connected to the top end of the support plate 10.

[0024] As Figure 1 shown, a convex block 4 is fixedly connected to the top end of the housing 1. The inside of the convex block 4 is the same as the surface of the support plate 10, which can limit the support plate 10, ensuring that the support plate 10 always remains in a non-deviating state during the up and down movement, thereby improving the position stability of the support plate 10 and further optimizing the stability of the overall structure.

[0025] As Figure 1 and Figure 4 shown, a striker tube 3 is fixedly connected to the position of the striker 2 at the top end of the support plate 10. The inner diameter of the striker tube 3 is the same as the outer diameter of the striker 2. Since the inner diameter of the striker tube 3 is the same as the outer diameter of the striker 2, it is used for the limit of the bottom end of the striker 2 to prevent the problem of deflection of the striker 2.

[0026] As Figure 2 and Figure 3 shown, one end of the bidirectional screw rod 9 away from the moving gear 7 is connected with a bearing 8 through interference fit. The bearing 8 is fixedly connected inside the housing 1, which can limit the bidirectional screw rod 9 and does not prevent the rotation of the bidirectional screw rod 9.

[0027] As Figure 2 and Figure 3 shown, the thread directions of the two bidirectional screw rods 9 are opposite, so that when the rotating button 5 rotates, the two bidirectional screw rods 9 move relative to each other. Through the relative movement of the two bidirectional screw rods 9 with opposite thread directions, the screw nuts 12 at the top ends of the bidirectional screw rods 9 move synchronously in the same direction, thereby achieving the purpose of adjusting the distance between the top end of the retractable support frame 13 and the ground.

[0028] As Figure 2 and Figure 3As shown in the figure, the retractable support frame 13 is composed of two X-folded rods and connecting blocks. The connecting blocks are fixedly installed at the four support corners of the X-folded rods. The connecting blocks and the lead screw nut 12 are rotatably connected by a round rod. The top of the connecting block and the bottom of the support plate 10 are rotatably connected by a round rod. The connecting block and the lead screw nut 12 can be rotatably connected by a round rod, which facilitates the folding of the retractable support frame 13, changes the folding difficulty of the retractable support frame 13, and thus achieves the purpose of facilitating the adjustment of the height of the support plate 10.

[0029] Working principle: Place the housing 1 on a flat surface, rotate the rotary button 5, drive the rotary shaft 6 to move the moving gear 7, and the moving gear 7 drives two static gears 11 to rotate two bidirectional lead screws 9. Since the threads of the two bidirectional lead screws 9 are opposite, when the two bidirectional lead screws 9 are rotated, the lead screw nuts 12 on the two bidirectional lead screws 9 move in the same direction. By rotating the bidirectional lead screws 9, the two lead screw nuts 12 on the outer surface of the bidirectional lead screws 9 move inward and merge. The retractable support frame 13 at the top of the lead screw nut 12 will open following the merging of the lead screw nuts 12. Since the retractable support frame 13 opens, the support plate 10 at the top of the retractable support frame 13 is slowly lifted. At this time, the striker 2 on the support plate 10 slowly appears from the top of the convex block 4;

[0030] After aligning and resetting the ink cartridge to be reset with the striker 2 at the top of the housing 1, rotate the rotary button 5 in the reverse direction to drive the moving gear 7 to drive the static gear 11 to move in the reverse direction. At this time, the lead screw nut 12 on the surface of a single bidirectional lead screw 9 moves in the reverse direction. As the distance between the two lead screw nuts 12 increases, the retractable support frame 13 at the top of the lead screw nut 12 contracts. During the contraction process, the support plate 10 at the top of the support frame 13 slowly descends, thereby achieving the process of retracting the striker 2. This effectively prevents mechanical damage caused by external factors such as impact or improper operation during the use of the resetter, thus greatly improving the stability and service life of the ink cartridge chip simple reset device.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it.
