Referring to fig. 3 and 4, the sliding base 30 is disposed on the rail 17 and can slide along the rail 17. The design of the sliding base 30 is various, in the present embodiment, the sliding base 30 includes a first wall portion 31, an upper connecting portion 33, the upper connecting portion 33 connects the top of the first wall portion 31, a lower connecting portion 35, the lower connecting portion 35 connects the bottom of the first wall portion 31, and a second wall portion 37, the second wall portion 37 connects the upper and lower connecting

portions

33, 35. The first and

second wall portions

31,37 are provided at the bottom with a sliding slot 32 for the axial rib 12 to extend into (as shown in fig. 10), so that the sliding seat 30 is radially constrained by the axial rib 12, and the sliding seat 30 keeps a fixed distance F from the imaginary axis L during sliding (as shown in fig. 9 and 14). In addition, the first and

second wall portions

31,37 and the upper and lower connecting

portions

33,35 together define a pivotal slot 34 (as shown in fig. 3).

Referring to fig. 3 and 9, the pivot member 40 is accommodated in the pivot slot 34 of the sliding seat 30, the pivot member 40 further includes a pivot portion 41, the pivot portion 41 is pivoted to the first wall portion 31 of the sliding seat 30 and abuts against the second wall portion 37, an inner end portion 43, the inner end portion 43 is closer to the imaginary axis L than the pivot portion 41, an outer end portion 45, the outer end portion 45 is farther from the imaginary axis L than the pivot portion 41, a first abutting portion 47, the first abutting portion 47 is located between the pivot portion 41 and the outer end portion 45, a second abutting portion 49, the second abutting portion 49 is located between the pivot portion 41 and the first abutting portion 47 and partially extends into the sliding slot 32 of the sliding seat 30 (as shown in fig. 10), and a protruding pillar 51, the protruding pillar 51 is located beside the pivot portion 41. Referring to fig. 4, a portion of the pivotal portion 40 extends through the slit 22, such that the pivotal portion 40 is constrained by the axial rib 12 and the restraining ring 14 and can swing between a retracted position I (shown in fig. 4 and 10) and an everted position O (shown in fig. 12 and 13) relative to the slider 30. Referring to fig. 9 and 10, when the pivot member 40 is located at the retracted position I, the distance between the outer end 45 and the imaginary axis L is D1, the first abutting portion 47 abuts against the first concave section 20b, and the second abutting portion 49 abuts against the second concave section 12b (as shown in fig. 10). On the other hand, referring to fig. 12 and 14, when the pivot element 40 is in the outward-turned position O, the distance between the outer end 45 and the imaginary axis L is D2, and D1 is smaller than D2. assuming that the pivot element 40 moves along the rail 17 to the position shown in fig. 14, the first abutting portion 47 abuts against the first convex arc segment 20a, and the second abutting portion 49 abuts against the second convex arc segment 12 a.

Referring to fig. 3, the restoring member 60 is connected at two ends thereof to the protruding pillar 51 of the pivotal swing member 40 and the second wall portion 37 of the sliding seat 30. The restoring member 60 applies a force to the pivotal member 40 to return to the retracted position I, and when the pivotal member 40 is not subjected to other external forces, the pivotal member 40 is located at the retracted position I. When an external force is applied to the pivotal member 40, the external force overcomes the force of the restoring member 60 to pivot the pivotal member 40 toward the outward-turned position O. It should be noted that the restoring member 60 is an extension spring, but in other embodiments, the restoring member 60 can also be a torsion spring, a compression spring, or other types of elastic components, but the connection manner of the restoring member 60, the pivoting member 40 and the sliding base 30 needs to be adjusted correspondingly as long as the pivoting member 40 can be restored to the retracted position I.

Referring to fig. 6, 8 and 10, the toner cartridge 1 may be installed in an electronic image forming apparatus 80 (e.g., a printer, a copier, etc.). Hereinafter, the upper right of fig. 6 is defined as the inside of the electronic imaging device 80, and the lower left of fig. 6 is defined as the outside of the electronic imaging device 80. The electronic imaging device 80 includes a housing 81, the housing 81 has a receiving space 82 for receiving the toner cartridge 1, a side cover 83, the side cover 83 is disposed on one side of the housing 81 and located at an inner end 82a of the receiving space 82, a door link 85, the door link 85 is movably disposed beside the receiving space 82, a spring 87, the spring 87 abuts against the side cover 83 and the door link 85 (as shown in fig. 10) with its two ends, and a powder-feeding sliding cover 89, the powder-feeding sliding cover 89 is movably disposed beside the receiving space 82. The housing 81 is further provided with a set of inlets 84 communicating with the accommodating space 82, and an opening edge of the set of inlets 84 is provided with a positioning notch 86 for the positioning block 28 to extend into. Referring to fig. 7, the side cover 83 includes a cover 91, a protrusion 93, the protrusion 93 is disposed on the cover 91 and is used for abutting against the inner end 43 of the pivoting member 40, and an end chamber 95, the end chamber 95 is disposed on the cover 91 and is located at the inward extending position of the door link 85. The side cover 83 has a central axis A, the central axis A is spaced apart from the outer edge of the protrusion 93 by a distance D3, the inner end 43 is spaced apart from the imaginary axis L by a distance D4 when the pivotal portion 40 is in the retracted position I, and D3 is greater than D4 (as shown in FIG. 10). Referring to fig. 10, the door link 85 includes a rod body 88 and a supported portion 90, and the supported portion 90 is disposed on the rod body 88 and supports the outer end 45 of the pivotal swinging member 40. Referring to fig. 10, when the door link 85 is located at a locking position B, the door link 85 can limit the movement of the powder sliding cover 89; referring to fig. 12, when the door link 85 is at a release position C, the powder sliding cover 89 can move. The spring 87 is received in the end chamber 95 and applies a downward force to the door link 85, and the spring 87 is compressed when the door link 85 is subjected to an external force upward in the drawing (see fig. 12).

Referring to fig. 4 and 10, before the toner cartridge 1 is not assembled into the electronic imaging device 80, the pivoting member 40 is only acted by the restoring member 60 and is located at the retracted position I. Referring to fig. 6 and 8, when the toner cartridge 1 is assembled into the electronic imaging device 80, the pivot member 40 is oriented substantially toward the door link 85 to assemble the toner cartridge 1 into the electronic imaging device 80 along the door link 85.

Referring to fig. 11, the toner cartridge 1 is assembled into the electronic imaging device 80 toward the upper side of the drawing, the central axis a overlaps the imaginary axis L, and the pivot portion 40 located at the retracted position I swings toward the outward-turned position O due to the inner end 43 thereof being abutted by the protrusion 93, so that the outer end 45 pushes against the abutted portion 90 of the door link 85, and the door link 85 and the outer end 45 extend into the end chamber 95. Referring to fig. 6 and 11, when the toner cartridge 1 is rotated counterclockwise in fig. 6, the outer end 45 is limited by the side wall of the end chamber 95 such that the sliding member 30 and the swinging member 40 do not rotate with the tubular member 11, i.e., the sliding member 30 and the swinging member 40 slide relative to the rail 17. When the first inclined guiding section 20c abuts against the first abutting portion 47 and the second inclined guiding section 12c abuts against the second abutting portion 49, the pivot swinging member 40 swings further toward the outward-turned position O. When the toner cartridge 1 accommodated in the accommodating space 82 rotates beyond a predetermined angle (e.g., 5-10 degrees), the swing member 40 moves to the first and second

convex arc sections

20a,12a and moves to the outward-turned position O under the action of the rail 17, so that the door link 85 is further pushed by the outer end 45 to further extend into the end chamber 95 and is located at the release position C (as shown in fig. 12). In addition, since the powder outlet cover 23 is restricted by the electronic imaging device 80 and does not rotate with the tube 11, the powder outlet cover 23 is moved away from the powder outlet 21 after the tube 11 rotates (as shown in fig. 16), and the powder inlet slide cover 89 which is not restricted by the door link 85 is pushed by the rotating toner cartridge 1 to leave the powder inlet (not shown) of the electronic imaging device 80. The toner cartridge 1 can be further rotated until the slide 30 is stopped by the limit ring 14 (as shown in fig. 13 and 14), at which time the positioning block 28 of the handle 19 moves to the positioning notch 86 and can extend into the positioning notch 86 (as shown in fig. 15), and the powder outlet 21 is opposite to the powder inlet, thereby completing the positioning.

Therefore, in the process that the user assembles the toner cartridge 1 into the electronic imaging device 80 and rotates the toner cartridge 1, the pivot swinging member 40 swings to the outward-turned position O under the action of the rail 17 and the protrusion 93, the pivot swinging member 40 extends into the end chamber 95 without rotating along with the pipe 11, so that the pivot swinging member 40 can continuously act on the door link 85 to remove the limitation of the movement of the powder-feeding sliding cover 89, and the user can easily rotate the toner cartridge 1 to the position shown in fig. 15 at one time.

On the other hand, when the user wants to take out the toner cartridge from the electronic imaging device, referring to fig. 15, the toner cartridge 1 is rotated clockwise in the drawing, when the pivoting member 40 moves to the first and second inclined guiding

sections

20c and 12c, the restoring member 60 acts on the pivoting member 40 (the spring 87 also acts on the door link 85 to push against the pivoting member 40), so that the pivoting member 40 swings toward the retracted position I until the pivoting member 40 moves to the first and second recessed

sections

20b and 12b (as shown in fig. 9 and 11). Referring to fig. 6, the toner cartridge 1 can leave the accommodating space 82 along the lower left side of the drawing, referring to fig. 10, and when the pivoting member 40 leaves the protrusion 93, the resetting member 60 can drive the pivoting member 40 to move to the retracted position I. In addition, when the swing member 40 leaves the door link 85, the door link 85 is moved to the locking position B by the spring 87, so that the movement of the powder sliding cover 89 rotated to be positioned is limited, thereby reliably closing the powder inlet. Therefore, the user can directly rotate the toner cartridge 1 from the position shown in fig. 15 to the position shown in fig. 6 to pull out the toner cartridge 1, the operation is very simple, and the electronic imaging device 80 can be reliably restored to the state that the toner cartridge 1 is not assembled.

It should be noted that the structure of the toner cartridge 1 may be changed based on the spirit of the present invention. For example, the first abutting portion 47 and the radial flange 20, the second abutting portion 49 and the axial flange 12 are respectively configured to enable the pivotal swing element 40 to be located at the retracted position I or the outward-folded position O, but in other embodiments, an arrangement may be selected (only the first abutting portion 47 and the radial flange 20, or only the second abutting portion 49 and the axial flange 12 may be provided); the shape of the pivotal swinging member 40 can be changed to allow it to swing directly to the outward-turning position O under the action of the protrusion 93, so that the first abutting portion 47 and the radial flange 20, the second abutting portion 49 and the axial flange 12 are omitted; the first and second inclined guiding sections 20c,12c are used to make the swing member 40 move smoothly between the first convex arc and the concave 20a,20b, and between the second convex arc and the concave 12a,12b, respectively, but the first and second inclined guiding sections 20c,12c can be either disposed or not disposed; the structure of the sliding seat 30 that can slide along the rail 17 is not limited to the sliding groove 32 and the axial rib 12, and any type of sliding rail design can be used; the bridge 18 is used to provide for the radial flange 20, although other structures for securing the radial flange 20 are possible; the handle 19 may have other shape variations as long as it is configured to facilitate user operation; the distance between the sliding seat 30 and the imaginary axis L is fixed in this embodiment because the axial rib 12 is arc-shaped, but in other embodiments, the shape of the axial rib 12 can be adjusted appropriately, and the distance between the sliding seat 30 and the imaginary axis L can be changed, as long as the swing portion 40 can swing to the outward-turned position O (against the door link 85).

The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
