Description

Technical Field

[0001] The utility model belongs to the field of preventing leakage of pigments, and particularly relates to an anti-leakage structure for installing an ink cartridge. Background Art

[0002] An ink cartridge is a container for a printer, which contains ink inside. It is an important component of the printer and is responsible for providing ink for printing. Ink cartridges are installed on the printer, and the printer identifies them through the metal sheets at the bottom ends of the ink cartridges, and then connects them to the printer through the ink outlets on the infusion tubes. In the prior art, during the installation of the infusion tube on the printer, the ink in the infusion tube cannot be effectively restricted in flow rate, resulting in too high a flow rate at the ink inlet end on the printer, causing ink leakage. Moreover, the sealing device of the ink injection port of the ink cartridge is relatively simple, and it is also easy to cause leakage at the ink injection port at the upper end of the ink cartridge. Summary of the Utility Model

[0003] In order to overcome the problems that during the installation of the ink cartridge, the liquid in the tube cannot be effectively restricted in flow rate during installation, resulting in too high a flow rate at the ink inlet end on the printer, causing ink leakage, and the sealing of the ink injection port of the ink cartridge is also relatively simple, which is also prone to leakage.

[0004] The technical solution of the utility model is: an anti-leakage structure for installing an ink cartridge, which includes an ink storage component; it also includes a cover component, a first sealing component, an infusion component and a second sealing component; a cover component for injecting ink is arranged on the ink storage component; a first sealing component for sealing is arranged on the cover component; an infusion component for infusion is arranged on the ink storage component; a second sealing component for sealing infusion is arranged on the infusion component.

When replacing, control the second sealing component to cause a break in the ink on the infusion component, and then take out the infusion component from the printer, which can prevent leakage and solve the problem that the infusion tube is prone to leakage due to too high a flow rate during the replacement and ink injection of the ink cartridge.

[0006] Preferably, the ink storage component includes a liquid storage box, a quick installation board, an electronic identification board and an outlet; the lower end of the liquid storage box is fixedly connected with the quick installation board and the electronic identification board; an outlet is opened at the rear end of the outer wall of the liquid storage box, and the inside of the liquid storage box is used for storing ink. The liquid storage box is installed on the printer through the quick installation board, so that the printer can identify the ink model through the electronic identification board.

By injecting ink into the second groove, the ink can enter the liquid storage box.

[0008] Preferably, the first sealing assembly includes a movable plate, a rubber sealing ring, a rocker arm, and an L-shaped block; the movable plate is hinged to the first groove; the outer wall of the movable plate fits with the inner wall of the first groove; a rubber sealing ring is fixedly connected to the lower end of the movable plate; the outer wall of the rubber sealing ring fits with the inner wall of the second groove; a rocker arm is rotatably arranged at the upper end of the movable plate; the lower end of the rocker arm fits with the upper end of the cover shell; an L-shaped block is fixedly connected to the lower end of the rocker arm; the L-shaped block is adapted to the arc groove; the L-shaped block passes through the third groove and extends to the inner wall of the arc groove. The rubber sealing ring on the movable plate is inserted into the second groove. By rotating the rocker arm, the L-shaped block on the rocker arm is first inserted into the third groove, and then the movable plate is rotated to drive the L-shaped block to slide on the inner wall of the arc groove, so that the L-shaped block slides to the outer wall of one end of the arc groove, thereby fixing the movable plate on the inner wall of the first groove and sealing the ink in the liquid storage box.

[0009] Preferably, the liquid infusion assembly includes an infusion tube and an ink outlet head; the infusion tube is fixedly connected to the rear end of the liquid outlet; the ink outlet head is fixedly connected to the outer wall of the infusion tube. By inserting the ink outlet head into the ink input end of the printer, the liquid infusion work is carried out. When multiple ink cartridges are installed together, multiple infusion tubes are connected in parallel through the ink outlet head.

[0010] Preferably, the second sealing assembly includes a current-limiting block, a first limiting groove, a first limiting block, a fourth groove, a fifth groove, a fixing block, a roller, a spring piece, a slot hole, and a column block; the current-limiting block is movably arranged on the outer wall of the infusion tube; a first limiting groove is opened at the right end of the current-limiting block; a first limiting block is fixedly connected to the left end of the current-limiting block; the shapes of the first limiting groove and the first limiting block are complementary; fourth grooves are opened through the front and rear ends of the current-limiting block; symmetrical fifth grooves are opened on the inner walls of the left and right ends of the fourth groove; the included angle between the inner wall of the lower end of the fifth groove and the inner wall of the lower end of the fourth groove is 45 degrees; rollers are rotatably arranged on the two fifth grooves; two fixing blocks are fixedly connected to the upper end of the current-limiting block; a spring piece is fixedly connected to the inner wall of the lower end of the fourth groove; slot holes are opened through the front and rear ends of the spring piece; the inner wall of the slot hole fits with the outer wall of the infusion tube; a column block is fixedly connected to the upper end of the spring piece. By sliding the roller, the outer walls of both ends of the roller slide on the inner wall of the fifth groove. When the roller slides to the outer wall of the rear end of the fifth groove, the outer wall of the roller squeezes the infusion tube, and at the same time the roller causes the upper end of the spring piece to deform downward, so that the spring piece squeezes the outer wall of the infusion tube, forming a sealed space inside the infusion tube in contact with the spring piece, which is convenient for carrying out the current-limiting work on the infusion tube.

[0012] Advantages of the present utility model:

[0013] 1. By inserting the rubber sealing ring on the movable plate into the second groove body, and rotating the rocker arm, the L-shaped block on the rocker arm is first inserted into the third groove body, and then the movable plate is rotated to drive the L-shaped block to slide on the inner wall of the arc groove, so that the L-shaped block slides to the outer wall of one end of the arc groove, thereby fixing the movable plate to the inner wall of the first groove body and sealing the ink in the liquid storage box, solving the problem of leakage caused by the insecure sealing of the liquid injection port on the liquid storage box;

[0014] 2. By sliding the roller, the outer walls of both ends of the roller slide on the inner wall of the fifth groove body. When the roller slides to the outer wall of the rear end of the fifth groove body, the outer wall of the roller squeezes the infusion tube, and at the same time the roller causes the upper end of the elastic piece to deform downward, so that the elastic piece squeezes the outer wall of the infusion tube, making a sealed space formed inside the infusion tube in contact with the elastic piece, solving the problem of inconvenient current limiting of the infusion tube and ink leakage when replacing the ink cartridge on the printer;

[0015] 3. By fixedly connecting the lower end of the elastic piece to the lower end of the inner wall of the fourth groove body, the upper end of the elastic piece can rotate. When the outer wall of the roller is attached to the upper end of the elastic piece, the upper end of the column block is limited to the concave part of the outer wall of the roller, thereby fixing the roller to the upper end of the elastic piece.
