detailed description

Figures 1 - 4 show a printer cartridge comprising a casing 1 comprising a front portion 2 and a rear portion 3, the casing 1 having a circumferential outer wall 4 on which an ink outlet is provided 5. An air inlet 6 and a fixing device for detachably mounting the ink cartridge on the print head carriage 100, the ink outlet 5 is located at the front portion 2 of the ink cartridge, and the fixing device includes a front portion 2 of the ink cartridge a fixing member 7 and a holder assembly 8 disposed at a rear portion of the ink cartridge, the holder assembly 8 including a fixing portion 813 at a bottom end of the rear portion of the casing for restricting the casing from coming out of the printing head carriage, the fixing portion 813 The bottom end of the rear portion of the casing can reciprocate in a horizontal direction; the fixing portion includes two working positions: when the fixing portion is located at the first working position, the fixing portion 813 is tightly connected with the printing head carriage 100, The printer ink cartridge is mounted in the print head interior 101; when the fixed portion is in the second working position, the fixed portion and the print head carriage are loose from each other, and the printer cartridge can be detached from the print head carriage. The utility model realizes two working positions of the fixing portion by the following scheme: the holder assembly 8 includes a releasing member, the releasing member includes a push rod 81 and a spring 82, and the push rod 81 includes a pressing end for pressing by a human hand 811, a pressing member 812 that is pressed against the spring, and a fixing portion 813 for restricting the ink cartridge escaping the carriage. The pressing end 811 and the fixing portion 813 are both connected to the pressing member 812, and the pressing end 811 and the fixing portion are fixed. A portion 812 extends from the outer wall 4 of the rear of the ink cartridge, and the release member is detachably disposed on the holder assembly 8.

The holder assembly 8 further includes a holder 83 having a space 831 matching the shape of the release member, the release member being detachably housed in the space 831, the rear portion of the ink cartridge The outer wall 4 of the frame 3 includes an outer wall 832 of the fixing frame, the pressing end 811 and the fixing portion 813 projecting from the outer wall 832 of the fixing frame, and the fixing frame 83 is detachably disposed at the rear portion 3 of the ink cartridge, the utility model The detachable manner is that an engaging groove 411 is defined in the rear wall 41 of the casing, and an insert 834 is disposed on the front wall 833 of the fixing frame, which is specifically a plug-in plate. Other plug-ins that are conventional in the art. In order to allow the push rod to move smoothly, the space 831 has a first guide groove 835 for moving the pressing end and a second guide groove 836 for moving the fixing portion. In order to prevent dust and protect the various components of the holder assembly, the holder 83 has a cover plate 84 that covers the space 831.

The push rod 81 of the present invention can have a variety of shapes, and Figures 5-6 illustrate two embodiments. Figure 5 shows a first embodiment, the shape is an inverted "L" shaped rod, the pressing end 811 is the first free end of the horizontal side 814 of the inverted "L" shaped rod, and the fixing portion 813 is the inverted The second free end of the vertical edge 815 of the "L" shaped rod has support members 816 on both sides of the inverted "L" shaped rod. The role of the support member 816 is to strengthen the strength of the push rod and improve the life of the push rod. The pressing member 812 is a contact portion of the vertical side of the inverted "L" shaped rod contacting the spring, and the center of the contact portion 813 is provided with a stud 817 perpendicular to the vertical side 815, and the spring 82 is sleeved on the convex portion The post 817 is pressed against the peripheral position of the stud 817 (i.e., the aforementioned contact portion). The function of the stud 817 is to restrict the movement of the spring. A spring is placed on the outer edge of the stud 817. The cavity 818 receives the spring 82. The second free end has a cross section of an inverted triangular hook shape. During operation, the ink cartridge is directly mounted. When the fixing portion 813 touches the fixing hole 102 of the carriage, the spring is compressed, and the fixing portion 813 moves horizontally and smoothly into the fixing hole 102, and enters the fixing hole 102 due to the inverted triangular structure of the fixing portion. Thereafter, the spring is reset, and the fixing portion 813 is horizontally moved in the opposite direction, so that the fixing portion 813 cannot be removed from the fixing hole 102. When the ink cartridge needs to be taken out, the pressing end 811 is pressed, and the spring 82 is compressed. Since the stud 817 is perpendicular to the vertical side 815, the force of the spring is perpendicular to the vertical side of the inverted "L" shaped rod, so that the fixed portion of the inverted triangle is horizontal. Moving, at this time, the ink cartridge is lifted upward, and the fixing portion is separated from the fixing hole 102, and the ink cartridge can be taken out.

Figure 6 shows a second embodiment of the pusher having a shape similar to that of the first embodiment, with the difference that a push end 811A is provided at the upper end of the horizontal side 814 of the push rod 81, and the push end 811A of the upper end is from the ink cartridge. The outer wall 832 of the upper upper end projects. Since the space around the rear of the ink cartridge is different, there are two pressing ends, which are more convenient for the operator to operate, and the operator can select any one of the pressing ends to operate. When the pusher of such a structure is placed in the ink cartridge, the pressing end 118 or the pressing end 118A is pressed, and the other actions are the same as above.

Since the fixing device further comprises a fixing member at the front portion of the ink cartridge, the fixing member may be some fixing cards of the prior art, or may be a fixing member made of an elastic material or a viscous material, in which case the fixing member is disposed at The outer wall of the casing has a sheet-like joint surface which is in contact with the inner wall surface of the print head and generates frictional force therebetween.

The holder assembly at the rear of the ink cartridge is attached to the front part of the ink cartridge, and the ink cartridge can be securely mounted on the carriage and can be easily removed.
