The sheet-like joint surface is made of an elastic material or/and a material having a viscosity.

The fixture further includes a holder assembly including a release member including a push rod and a spring, the push rod including a pressing end for pressing by a human hand, and a pressing against the spring And a fixing portion for restricting the ink cartridge from coming out of the print head carriage, the pressing end and the fixing portion are both connected to the pressing member, and the pressing end and the fixing portion are from the box The outer wall of the rear portion of the body projects, the release member is detachably disposed on the holder assembly, and the holder assembly is disposed at a rear portion of the case.

The elastic material is silica gel or rubber.

The viscous material is a viscous material made by adding a binder to the fibers.

The fibers are cotton, hemp, wool or chemical fibers.

The fixing member is a sheet having an "L" shape in cross section, the sheet-shaped joint surface is integral with the fixing member, and the outer wall of the box body comprises a front wall, a top wall, a rear wall and a bottom wall. The fixing member is attached to the first intersection of the front wall and the top wall of the ink cartridge or/and the second intersection of the front wall and the bottom wall.

The fixing member is a sheet having a cross-sectional shape of "one", the sheet-shaped joint surface is integral with the fixing member, and the outer wall of the box body comprises a front wall, a top wall, a rear wall and a bottom wall. The fixing member is attached to at least one wall surface of the front portion of the ink cartridge.

A portion of the ink cartridge that is in adhesive contact with the fixing member is provided with a groove, and the groove receives the fixing member.

The beneficial effects of the utility model are:

Compared with the prior art, the utility model adopts a fixing member having a sheet-like joint surface made of elastic or adhesive, or both elastic and viscous materials, and the fixing member has a very simple structure, is easy to process, and has elasticity. The sheet-like joint surface of the fixing member is mounted on the outer wall of the ink cartridge. When the portion is in contact with the corresponding position of the inner surface of the carriage, when the gap between the inner surface of the carriage and the outer wall of the ink cartridge is smaller than the thickness of the fixing member, the fixing member is subjected to a certain pressure. At this time, since the fixing member has a certain resilience, a large frictional force is generated between the sheet-like joint surface and the inner wall surface of the carriage, which functions to fix the ink cartridge. The adhesive sheet-like joint surface has adhesive force, and when the sheet-shaped joint surface and the inner surface of the carriage can be bonded together, a large frictional force is generated between the sheet-shaped joint surface and the inner wall surface of the carriage to fix the ink cartridge. effect. Since the fixing member plays a fixed role as long as it is in contact with the inner surface of the car, there is substantially no precision requirement during processing, and substantially no parts need to be processed in the corresponding parts in contact with the carriage, which reduces the processing cost. Since the elastic material or the viscous material does not age, its fixing effect is always present, it is not easy to be damaged, and the life is long.

detailed description

1 shows a printer cartridge of the present invention, comprising a casing 1 comprising a front portion 2 and a rear portion 3, having a surrounding outer wall 4, the casing 1 being provided with an ink outlet 5, An air inlet 6 and a fixing device for detachably mounting the ink cartridge on the print head carriage, the ink outlet port 5 is located at the front portion 2 of the casing, and the outer wall 4 includes a front wall 41 and a top wall 42. The rear wall 43 and the bottom wall 44 are in contact with the bottom 101 of the carriage 100 when the ink cartridge is loaded into the print head carriage 100. The fixing device comprises a fixing member 7 disposed on the outer wall 4 of the ink cartridge, the fixing member having a sheet-like engaging surface 71 in contact with the printing head carriage, the sheet-like engaging surface 71 being made of elastic material or / and made of a material that is sticky. The fixing member 7 can be placed at any position on the outer wall 4, see Figs. 6-9. As a preferred solution, it may be provided on the outer wall 4 of the front portion 2 of the ink cartridge. Specifically, referring to Figures 6 and 8, the fixing member 7 is disposed on the front wall 41, the front wall 42 of the front portion or the bottom wall 44 of the front portion.

The elastic material is preferably silica gel or rubber, and may be other elastic materials. The silicone rubber and the rubber are elastic and resilient when subjected to pressure, causing a large frictional force between the contact surface of the inner wall surface 102 of the print head carriage, thereby fixing the ink cartridge to the print head carriage. The viscous material may be a viscous material made by adding a binder to fibers (such as cotton, hemp, wool, chemical fibers, etc.) or leather materials. The adhesive is a prior art adhesive such as a commercially available clear adhesive or a double-sided adhesive. It is also possible to add an adhesive to the elastic material silicone or rubber. Such a fixing member is elastic and viscous, and the fixing member is more firmly fixed.

At the same time, the pressure is connected or pasted to the corresponding position on the inner wall surface of the print head. It is also possible that the sheet-like joint surface is in contact with the fixing member to form a sheet. At this time, the two sides of the fixing member are different in material, one side is mounted on the outer wall of the ink cartridge, and the other side is a sheet-shaped joint surface. When the ink cartridge is mounted on the word car, it is connected or adhered to the corresponding position of the inner wall surface of the print head.

4 and 5 show the fixing member 7 as a sheet having a cross-sectional shape of "one", the sheet-shaped joint surface and the The fixing piece is a whole, and the possible situation is the same as above.

6 to 9 show several cases in which the fixing members 7 are disposed at different positions of the outer wall. Of course, the present invention is not limited to these kinds of cases, as long as those skilled in the art can think of the protection range of the present invention. Inside. The fixing member having an "L" shape in cross section may be attached to the first intersection 45 of the front wall and the top wall of the casing and/or the second intersection 46 of the front wall and the bottom wall. The fixing member having a "one" shape in cross section may be attached to at least one wall surface of the front portion of the ink cartridge.

In order to securely attach or fix the fixing member to the outer wall of the casing, a portion of the ink cartridge that is in adhesive contact with the fixing member is provided with a groove 9 for accommodating the fixing member 7.

The fixing device may include a holder assembly 8 disposed at the rear of the casing in addition to the aforementioned fixing member. Referring to Fig. 1, the holder assembly 8 includes a release member including a push rod 81 and a spring 82, the push rod 81 including a pressing end 811 for human hand pressing, and a pressing member pressed against the spring. 813 and a fixing portion 812 for restricting the ink cartridge escaping carriage, the pressing end 811 and the fixing portion 812 are both connected to the pressing member 813, and the pressing end and the fixing portion protrude from the outer wall 4 of the rear portion of the ink cartridge The release member is detachably disposed on the holder assembly. The holder assembly also includes a holder 83 having a space 831 that matches the shape of the release member, the release member being removably received in the space 831.
