Therefore, the unlocking assembly 5 in the present embodiment is a combination of the above embodiments, and for an end user, the movement manner of the unlocking assembly 5 in the present embodiment is not changed, that is, when the ink cartridge 1 needs to be taken out, the end user needs to apply a pressing force to the unlocking assembly in the-z direction, so that the user experience of the ink cartridge 1 with the unlocking assembly 5 is better; meanwhile, as the unlocking assembly 5 does not rotate around the fixed fulcrum any more but does linear motion along at least one of the x direction or the z direction, the requirements on the dimensional accuracy and the mounting position accuracy of the unlocking assembly 5 can be reduced.

[ example five ]

The unlocking assembly 5 in the present embodiment includes a moving member 50 and a ball 54 which are combined with each other, the moving member 50 is rod-shaped as a whole, and includes an intermediate rod 53, and a force receiving portion 51 and an acting portion 52 which are connected to the intermediate rod 53, wherein the force receiving portion 51 is located in the-x direction of the acting portion 52, the ball 54 is located between the moving member 50 and the box body 2, and one of the force receiving portion 51 and the acting portion 52 is lifted by rolling the ball 54 in the x direction; to ensure stable rolling trajectory of the ball 54, as shown in the drawing, the moving member 50 is provided with a guide groove 533 extending in the x direction on a bottom surface 532 thereof, and the ball 54 rolls along the guide groove 533; further, the unlocking member 5 further includes a holding member for holding the spherical body 54 at the initial position, for example, a protrusion provided in the case 2 or the guide groove 533, and when the ink cartridge 1 is not mounted, the spherical body 54 is held by the holding member at the initial position close to the force receiving portion 51, and at this time, the moving member 50 as a whole is in an inclined state with the spherical body 54 as a fulcrum, and the force receiving portion 51 is located above the acting portion 52 in the z direction.

In the process of mounting the ink cartridge 1 to the printer, the position of the moving member 50 is not changed, when the ink cartridge 1 is mounted to a predetermined position of the printer, the urging surface 401 abuts against the force-bearing surface 231, when the ink cartridge 1 needs to be taken out, the end user presses the force-bearing portion 51, the ball 54 is pressed and overcomes the holding force of the holding member, the ball rolls along the guide groove 533 in the + x direction, the moving member 50 starts to rotate with the ball 54 as a fulcrum, the force-bearing portion 51 moves in the-z direction, the acting portion 52 moves in the + z direction, and simultaneously, the acting portion 52 pushes the blocking member 40 away from the force-bearing surface 231, and the ink cartridge 1 is withdrawn in the-x direction under the elastic restoring force of the spring in the guide portion 22.

When the ink cartridge 1 is mounted again, the stopper 40 moving in the-z direction presses the acting portion 52, the ball 54 rolls again along the guide groove 533 toward the force receiving portion 51, the moving member 50 rotates again about the ball 54 as a fulcrum during the rolling of the ball 54, the force receiving portion 51 gradually rises, and the acting portion 52 gradually falls until the ball 54 returns to the initial position held by the holder again.

It can be seen that, after the moving element 50 in the present embodiment is subjected to an external force, the ball 54 is used as a fulcrum to rotate, and since the ball 54 can roll in the guide groove 533 along the x-square, the rotation fulcrum is not fixed any more, but changes along with the rolling of the ball 54, the moving element 50 in the present embodiment is more flexible, and the requirement on the dimensional accuracy and the installation position of the unlocking assembly 5 as a whole is reduced.

Specifically, the second action block 5b is connected with the force-bearing plate 23 and extends linearly from the force-bearing plate 23 to the-x direction, and at this time, the surface of the second action block 5b in the + z direction is higher than the force-bearing surface 231; or, the second action block 5b is connected with the force-bearing plate 23 and extends obliquely from the force-bearing plate 23 to the-x direction, that is, the second action block 5b is farther from the top surface 24 of the cartridge body along the-x direction, at this time, it is not necessary that the whole second action block 5b is located in the + z direction of the force-bearing surface 231, and it is only necessary to ensure that the part of the second action block 5b contacting the blocking member 40 can push the blocking member 40 away from the force-bearing surface 231 when the ink cartridge 1 is mounted to the predetermined position of the ink jet printer, and the part of the second action block 5b contacting the blocking member 40 is higher than the force-bearing surface 231; alternatively, the second action block 5b is connected to the first action block 5a and can move with the first action block 5a in the z direction, and when the first action block 5a is completely combined with the rib plate 411, the contact part of the second action block 5b and the blocking member 40 is higher than the force bearing surface 231.

As shown in fig. 9, when the stopper 40 is urged in the-z direction by the spring 42, the second action piece 5b comes into contact with the lower surface 404 of the stopper 40, urging the stopper 40 in the + z direction against the elastic force of the spring 42; when the blocking member 40 rotates about the axis at one end in the x direction, the second action piece 5b remains in contact with the lower surface 404 of the blocking member 40, urging the blocking member 40 in the + z direction against the weight of the blocking member 40.

The first action block 5a comprises a main body 5a2, a combining part 5a3 arranged on the main body 5a2 and a guided part 5a4/5a5, wherein the combining part 5a3 is used for being combined with the rib plate 411, and the guided part 5a4/5a5 is used for guiding the first action block 5a, so that the first action block 5a can move linearly in the z direction. The combining part 5a3 and the guided part 5a4/5a5 are respectively protrusions extending from the main body 5a2 in the z direction, wherein the combining part 5a3 extends from the main body 5a2 to the + z direction, the guided part 5a4/5a5 extends from the main body to the-z direction, and the guided part 5a4/5a5 are two protrusions arranged in parallel, so that the first acting block 5a does not tilt when moving in the z direction, and the acting force applied to the first acting block 5a is ensured to be more stable.

Accordingly, the case 2 is provided with the guide holes 2a2/2a1 for guiding the guided portions 5a4/5a5, the case 2 in this embodiment includes the first case 2a and the second case 2b combined in the y direction, and the guide holes 2a2/2a1 may be provided on any one of the first case 2a and the second case 2 b; further, the unlocking assembly 5 further includes an elastic restoring member 5c combined with at least one guided portion 5a4/5a5, the elastic restoring member 5c being used for forcing the combined portion 5a3 to move away from the box body 2, for example, the elastic restoring member 5c is a compression spring disposed between the guided portion 5a4/5a5 and the box body 2.

Taking the compression spring 5c sleeved on the outer surface of the guided portion 5a5 as an example, as shown in fig. 9, the guided portion 5a is a cylinder and includes a first portion 5a51, a boss 5a53 and a second portion 5a52 which are sequentially arranged from the main body 5a2 to the-z direction, and the compression spring 5c is sleeved on the second portion 5a 52; the guide hole 2a1 includes a first fitting portion 2a12 fitted with the first portion 5a51, a second fitting portion 2a13 fitted with the second portion 5a52, and an intermediate portion 2a11 fitted with the boss 5a53, wherein the maximum dimension of the boss 5a53 is larger than the maximum dimension of both the first fitting part 2a12 and the second fitting part 2a13, the compression spring 5c is located between the boss 5a53 and the second fitting part 2a13, the second case 2b is provided with a lid portion 2b1 corresponding in shape to the first engaging portion 2a12, the second engaging portion 2a13, and the intermediate portion 2a11, when the first box member 2a and the second box member 2b are combined, the lid portion 2b1 corresponds to the first engaging portion 2a12, the second engaging portion 2a13 and the middle portion 2a11, thereby forming the guide hole 2a1, and thus, the range of movement of the guided portion 5a5 in the z direction is limited, and the first action piece 5a does not fall out of the case body 2; meanwhile, the first acting block 5a may be installed in the same direction as the direction in which the first case 2a and the second case 2b are fastened, so that the first acting block 5a is conveniently installed. Of course, the compression spring 5c may also be sleeved on the first portion 5a51, in which case, one end of the compression spring 5c abuts against the boss 5a53, and the other end abuts against the first matching portion 5a 51.

The tendency of the first action block 5a to be kept away from the cartridge body 2 by the compression spring 5c before the ink cartridge 1 is mounted; when the ink cartridge 1 is mounted in the + x direction, the second action piece 5b lifts the blocking member 40 in the + z direction so that the blocking member 40 is not engaged with the force-receiving surface 231, and at the same time, an external force is applied to the main body 5a2 in the-z direction, the compression spring 5c is compressed, the first action piece 5a moves in the-z direction toward the cartridge body 2, and when the engaging portion 5a3 passes below the rib 411 in the (-z direction), the external force is cancelled, the first action piece 5a moves in the + z direction by the elastic restoring force of the compression spring 5c, the engaging portion 5a3 reaches the + x direction of the rib 411, and the ink cartridge 1 is fixed/locked in the ink jet printer.

When the ink cartridge 1 needs to be taken out, similarly, an external force is applied to the main body 5a2, the first action piece 5a moves in the-z direction, the compression spring 5c is compressed until the joint portion 5a3 reaches below the rib 411, the ink cartridge 1 moves in the-x direction by the spring force in the guide portion 22, and at the same time, the external force is cancelled, and the first action piece 5a moves in the + z direction by the elastic restoring force of the compression spring 5c to be restored.

Like the fourth embodiment, the unlocking assembly 5 in this embodiment does not rotate around the fixed fulcrum any more, but does linear motion along the z direction, and the requirements on the dimensional accuracy and the mounting position accuracy of the unlocking assembly 5 can be reduced.
