Abstract

An ink box includes an ink box main body to contain ink, an ink outlet on the ink box main body to guide the ink out from the ink box main body, a chip fixing part at one skirt board of the ink box main body, a piloting part matched with the guiding groove in printing device, an elastic handle designed to combine with printer and provide at the extension part of the ink box main body's underside and extending along the direction away from the side wall. Ink box disclosed by the utility model has the advantages that: it has a longer supporting arm of force and a larger elasticity range; the ink box could be installed and removed by lesser force; and the ink box could be fixed with higher reliability.

Description

Print cartridge

Technical field

The utility model relates to a kind of print cartridge that is used on the ink-jet printer, especially relates to a kind of print cartridge that chip is installed.

Background technology

Along with popularizing of electronic computer, the scope of application of printer is also more and more wider, and ink-jet printer is because less expensive, thereby is more adopted by ordinary consumer.

6,979, No. 079 U.S. Patent Publication a kind of print cartridge that chip is installed, it comprises a toner cartridge main body that is used to hold ink, toner cartridge main body bottom has an ink outlet port.The first side wall bottom at toner cartridge main body is provided with the chip installation portion, and a chip that records ink information is fixed in this chip installation portion; For guaranteeing that the conductive contact on the chip can be electrically connected with printer reliably, second sidewall of toner cartridge main body is provided with resilient handle, this resilient handle along on the position of print cartridge direction of insertion than the position height of chip fixed part; Second sidewall bottom at resilient handle place is provided with a vertically protruding guide portion, and when being installed to print cartridge on the printer, this guidance part can play guiding function makes installation process more smooth and accurate.In the time of in print cartridge is installed to printer, the flexible corresponding lock catch part of printer that is buckled in of resilient handle is fixed on print cartridge in the printer on the one hand, make on the other hand conductive contact on the chip can be reliably with printer on corresponding contact electrical connection.Because the print cartridge resilient handle extends from the middle part of toner cartridge main body, it is shorter to cause supporting the arm of force, and the scope of strain is less, need apply bigger power when installing and take out print cartridge buckle and snap close are freed, and the print cartridge reliability of fixation is also relatively poor.

Summary of the invention

The purpose of this utility model provide a kind of can be with the PRN device secure fixation, guarantee to be electrically connected the print cartridge that can install easily or take out again.

For achieving the above object, the print cartridge that the utility model provides comprises the toner cartridge main body that is used to hold ink, be positioned on the toner cartridge main body and be used for ink is derived the outer ink outlet port of toner cartridge main body, be positioned at the chip installation portion on sidewall of toner cartridge main body, the guide portion that matches with guide channel on the PRN device, be used for the resilient handle that fastens with printer, from the diapire of toner cartridge main body extension arranged, resilient handle is arranged on the extension and along the direction away from sidewall and extends upward.

Compare with previous technology, the utlity model has following effect: resilient handle extends out from the extension of print cartridge diapire, it is longer to support the arm of force, and elastic range is bigger, can reach install and when taking out print cartridge the application of force less and improve the effect of the reliability of print cartridge fixedly the time.

According to the technical solution of the utility model, the guide portion of print cartridge is located on the extension of toner cartridge main body bottom surface, from the extension longitudinal extension that makes progress.Print cartridge matches with guide channel on the PRN device by guide portion, can make installation process more accurate and convenient.

Description of drawings

Fig. 1 is the schematic diagram of the utility model first embodiment;

Fig. 2 is the left view of print cartridge shown in Figure 1;

Fig. 3 is the schematic diagram of the utility model second embodiment;

Fig. 4 is the left view of print cartridge shown in Figure 3.

The utility model is described in further detail below in conjunction with each figure and most preferred embodiment.

The specific embodiment

Referring to Fig. 1 and Fig. 2, print cartridge 1 has a toner cartridge main body 10, and this toner cartridge main body 10 is surrounded by roof, front and back walls, first,

second sidewall

11,12 and diapire 13, and diapire 13 is provided with ink outlet port 14, and ink outlet port 14 communicates with toner cartridge main body 10 inner chambers.Described diapire 13 comprises an extension 130, and this extension 130 is along slightly extending outside second sidewall 12 away from the direction of second sidewall 12.Extension 130 places at toner cartridge main body 10 diapires 13 are provided with resilient handle 15, and this resilient handle 15 is to extend upward out along the direction away from second sidewall 12 from extension 130.Also further be provided with the projection that vertically is provided with along second sidewall 12 on extension 130, this projection is a guide portion 16, and when print cartridge 1 was installed, this guide portion 16 matched with corresponding guide channel (not shown) in the printer, plays guiding and installs.A chip installation portion 17 is arranged at the bottom of the first side wall 11 of toner cartridge main body 10, and the outer surface of this chip installation portion 17 is provided with a chip resettlement section (not shown), and this chip resettlement section is used to hold and fixed chip.Be provided with a projection 151 on resilient handle 15, when print cartridge 1 was installed in the printer, projection 151 engaged with buckle on the printer, thereby print cartridge 1 is fixed in the printer reliably.At this moment, the contact of the chip on the chip installation portion 17 forms reliable electrical connection with corresponding contact on the printer.

With reference to Fig. 3 and shown in Figure 4, in another embodiment of the present utility model, the guide portion 16 of print cartridge 1 is installed on the resilient handle 15, vertically extends upward setting from resilient handle 15.

Print cartridge described in the utility model, its resilient handle 15 extends out from the bottom of print cartridge, and it is longer to support the arm of force, and elastic range is bigger, only need execute less power and just can install and take out print cartridge, and the reliability of print cartridge fixedly the time is higher.

Technical conceive of the present utility model is not limited in the foregoing description, can also obtain many different concrete schemes according to design of the present utility model, for example, guide portion can also be located at the bottom or the middle part of resilient handle, on first,

second sidewall

11,12 of toner cartridge main body 10 resilient handle 15 or the like is set simultaneously.All should be included within the described scope of claim such as these minor alterations and equivalent transformation.
