Description

Technical Field

[0001] The utility model relates to the technical field of printing consumables, in particular to an ink cartridge. Background Art

[0002] Many existing inkjet printers typically use replaceable ink cartridges as ink reservoirs to supply the printer with ink. The ink cartridge is equipped with a chip, and the printer is equipped with a stylus. When the ink cartridge is installed in the printer, the chip contacts the stylus to establish an electrical connection, thereby enabling electrical communication between the ink cartridge and the printer. The ink cartridge also has a mounting bracket and an elastic member. The chip is fixed to the mounting bracket, which is connected to the ink cartridge via the elastic member. The elastic force of the elastic member presses the chip against the stylus. However, the elastic member is prone to expansion and contraction, causing the mounting bracket to wobble relative to the ink cartridge, affecting the contact stability between the chip and the stylus.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 and Figure 210. The ink cartridge shown in FIG. 10 is detachably installed in a printer. The ink cartridge of this embodiment includes a cartridge body 100, a sliding locking portion 110, and a mounting bracket 120. The cartridge body 100 is provided with a mounting groove 101. The sliding locking portion 110 is movably arranged in the mounting groove 101. When the sliding locking portion 110 is subjected to force or is blocked during the movement of the cartridge body 100, the sliding locking portion 110 can move relative to the cartridge body 100 in the mounting groove 101. An inclined abutting surface 111 is formed on the outer side of the sliding locking portion 110. The mounting bracket 120 is rotatably arranged on the mounting groove 101 and is located on the outer side of the sliding locking portion 110, that is, the inner side surface of the mounting bracket 120 abuts against the inclined abutting surface 111 of the sliding locking portion 110. 1. A chip 121 is mounted on the outer side of the mounting bracket 120. The sliding locking portion 110 moves relative to the box body 100 in the mounting slot 101 and can drive the mounting bracket 120 to rotate through the inclined abutment surface 111, so that the chip 121 contacts the stylus 201 in the printer. When the sliding locking portion 110 is blocked in the mounting slot 101, the mounting bracket 120 can be mechanically locked, thereby avoiding the problem of poor contact between the chip 121 and the stylus 201 caused by the mounting bracket 120 rotating relative to the box body 100. That is, the present invention blocks the sliding locking portion 110 at a certain position in the mounting slot 101 and mechanically locks the mounting bracket 120, thereby ensuring that the chip 121 always contacts the stylus 201 in the printer.

[0025] In some possible embodiments, reference Figure 3 As shown, this part only shows the structure for installing the box body 100 in the printer. Specifically, a fixing groove 202 is provided in the printer, and a blocking surface 203 is formed at the bottom of the fixing groove 202. During the process of inserting the box body 100 into the fixing groove 202 from top to bottom, the lower end of the sliding locking part 110 is first blocked by the blocking surface 203, so that the sliding locking part 110 moves relative to the box body 100 in the installation groove 101, and then the inclined abutment surface 111 forces the mounting frame 120 to rotate relative to the box body 100 toward the direction of the chip 121 close to the contact pin 201. After the box body 100 is installed in place, the sliding locking part 110 is always blocked by the blocking surface 203. Therefore, the sliding locking part 110 also always plays a role of mechanical locking on the mounting frame 120, thereby ensuring that the chip 121 always contacts the contact pin 201 in the printer after the box body 100 is installed in place.

[0026] In some possible embodiments, a support arm 112 is provided at the lower end of the sliding locking portion 110, and the support arm 112 extends out of the installation slot 101 to ensure that during the installation of the ink cartridge, the sliding locking portion 110 first contacts the blocking surface 203 and is pressed to move relative to the box body 100, thereby forcing the mounting frame 120 to rotate relative to the box body 100.

[0027] In some possible embodiments, an elastic member 102 is further provided in the mounting groove 101, and the elastic member 102 can be a conventional compression spring. One end of the elastic member 102 is connected to the upper end surface of the sliding locking portion 110, and the other end is connected to the upper side wall of the mounting groove 101. Under normal circumstances, the elastic member 102 is always compressed, that is, the elastic member 102 always gives the sliding locking portion 110 a force away from the mounting frame 120 to ensure that under normal circumstances, the sliding locking portion 110 does not force the mounting frame 120 to rotate relative to the box body 100, so that the chip 121 protrudes from the surface of the box body 100, thereby avoiding the risk of the chip 121 being compressed or damaged by collision during packaging and transportation.

[0028] In some possible embodiments, one end of the mounting frame 120 is hinged to the box body 100, the chip 121 is arranged at the other end of the mounting frame 120, and the chip 121 is arranged on the outer side surface of the mounting frame 120, and the inclined abutting surface 111 abuts against the inner side surface of the mounting frame 120 having one end of the chip 121, that is, the inclined abutting surface 111 acts on the end of the mounting frame 120 away from the end thereof hinged to the box body 100.

[0029] In some possible embodiments, reference Figure 2 As shown, two symmetrical mounting guide grooves are provided on the box body 100, an inclined guide surface 104 is formed on the upper portion of the mounting guide groove, and a hinge countersunk hole 105 is formed on the lower portion. Hinge pins 122 are formed on opposite sides of the mounting frame 120. During installation, the hinge pins 122 are inserted into the mounting guide grooves and pass over the inclined guide surfaces 104 and are then placed in the hinge countersunk holes 105. In this way, the mounting frame 120 is stably and rotatably connected to the box body 100, and the mounting frame 120 is not easy to fall out.

[0030] In some possible embodiments, guide grooves 106 are further provided on opposite sides of the mounting groove 101, and guide portions 113 are formed on opposite sides of the sliding locking portion 110. The guide portions 113 are placed in the guide groove 106 and reciprocate along the axial direction of the guide groove 106 with the sliding locking portion 110 to limit the reciprocating movement direction of the sliding locking portion 110 in the mounting groove 101.

[0031] In some possible embodiments, reference Figure 1 and 2 As shown, the box body 100 is also provided with an integrally formed elastic handle 107, which is located at the upper end of the installation slot 101. A card slot 108 is provided on the outer side of the elastic handle 107. The printer is provided with a fixed clip 204 that cooperates with the card slot 108. After the box body 100 is installed in place, the fixed clip 204 is inserted into the card slot 108 to fix the box body 100 in the printer. When disassembling, it is only necessary to press the elastic handle 107 to separate the card slot 108 from the fixed clip 204, and the box body 100 can be taken out of the printer from bottom to top.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
