Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Features of the embodiments described below may be combined with each other without conflict.

Embodiment one:

referring to fig. 1 to 2, the present embodiment discloses a printer sheet cassette 1 including: the box body 2 with the lateral opening 21, the cover body 4 for closing the lateral opening 21 and the sheet tray 3 are arranged, the sheet tray 3 is provided with a placing groove 31 for placing printing sheets such as printing paper, films and the like, the sheet tray 3 is jointed in the box body 2 in a mode of being capable of moving along a set direction, and the moving can be realized in a mode of adopting a matching structure of a sliding rail and a sliding block, a matching structure of a gear and a rack and the like. Specifically, in this embodiment, as shown in fig. 2, the box 2 includes a base 22 and an upper casing 23 covered on the base 22, a containing space 24 for containing the sheet tray 3 is formed between the upper casing 23 and the base 22, a sliding slot for sliding the sheet tray 3 is formed on an inner wall of the base 22, and a sliding portion adapted to the sliding slot is provided on the sheet tray 3, so that the sliding fit between the sliding portion and the sliding slot is used to realize the movable movement. Wherein the lateral opening 21 is adapted for the sheet tray 3 to extend to form a docking end for a docking printer and retract to the cassette 2 to form a stowed condition for the sheet tray 3.

In this embodiment, in order to facilitate the user to extend or remove the sheet tray 3 from the lateral opening 21, a guiding chute 7 is disposed on the bottom wall of the base 22 along the extending direction, a sliding operation portion 8 is disposed in the guiding chute 7, the sliding operation portion 8 is engaged with the sheet tray 3, and the user pushes the sliding operation portion 8 to drive the sheet tray 3 to move along the extending direction to extend the lateral opening 21. Naturally, the guide chute 7 forms a limit to the slide operation portion 8 along both side walls in the extending and retracting directions in the chute body, so that the extending length of the sheet tray 3 is also limited to a certain range to prevent the sheet tray 3 from coming off the cassette 2.

Referring to fig. 3, in this embodiment, the cover 4 is pivotally connected to the case 2 in a reversible manner. The cover 4 has a pivot 25, and the case 2 is provided with a pivot hole adapted to the pivot 25 so that the cover 4 can rotate around the pivot 25. In the present embodiment, the pivot shaft 25 is fixedly coupled to the cover 4, but in other manners, the pivot shaft 25 may be movably coupled to the cover 4 with respect to the cover 4. In addition, the pivot hole in this embodiment is engaged near the lower portion of the base 22, preferably at the bottom wall of the base 22. The sheet tray 3 is provided with a pushing structure 5 for pushing the cover 4 to be turned over to a supporting position where the cover 4 is located below the case 2 and can support the case 2.

Next, the above-described scheme will be described in detail with reference to fig. 4 to 7, wherein fig. 4 to 6 show schematic views of the cover 4 being flipped to the open position, fig. 6 to 7 show schematic views of the cover 4 being flipped to the supporting position, and arrow X1 shows the direction of extension of the sheet tray 3. When the sheet tray 3 passes through the lateral opening 21, the pushing structure on the sheet tray 3 pushes the cover 4 to turn over step by step until the cover 4 turns over to below the cassette 2 and the lower portion of the cover 4 is borne on the supporting surface, the upper portion of which can support the cassette 2, that is, even if the cassette 2 is held substantially at a set height position at which the sheet tray 3 in the cassette 2 can be substantially aligned with the paper feed port of the printer, so that the sheet tray 3 is reliably fitted to the printer and the sheet tray 3 is prevented from falling off from the paper feed port. Compared with the conventional scheme of additionally providing the supporting member, the present embodiment skillfully uses the rotatable cover 4 as the structure for supporting the cassette 2 without separately manufacturing and assembling the supporting member for supporting the cassette, thereby effectively reducing the production cost of the sheet cassette 1, and also without damaging the structures of the sheet tray 3 and the cassette 2, thereby improving the structural strength of the sheet cassette 1.

In this embodiment, as shown by arrow S1, the pushing structure 5 includes: a first pushing portion 51 and a second pushing portion 52, the first pushing portion 51 being adapted to push the lid 4 to be turned to the open position, as shown in fig. 4 to 6, which is a process of turning. The second pushing portion 52 is adapted to push the lid 4 to continue to flip from the open position to the supporting position, as illustrated in fig. 6 to 7, which is the process of continuing to flip. Wherein in said open position the cover 4 opens said lateral opening 21 for the sheet tray 3 to extend. The first pushing portion 51 and the second pushing portion 52 may be configured in the form of a wedge having at least one inclined surface facing the cover 4, wherein the first pushing portion 51 is provided at the front end of the sheet tray 3 and is formed by the front end of the sheet tray 3 protruding outward. Preferably, the first pushing portion 51 in the present embodiment is provided on the front end surface of the sheet tray 3 at a position near the middle so that the cover 4 is relatively balanced when being stressed, and the second pushing portion 52 is provided on the side wall of the sheet tray 3. Further, a movable space is formed between the sheet tray 3 and the inner wall surface of the case 2, a second pushing portion 52 is formed by projecting the side wall of the sheet tray 3 outward and is located in the movable space, and the second pushing portion 52 is located at the rear side of the first pushing portion 51 in the projecting direction of the sheet tray 3.

Referring to fig. 7, in the present embodiment, the first pushing portion 51 has an abutment surface 511 that abuts against the cover 4, and in the present embodiment, the abutment surface 511 may be an inclined surface or an arc surface. The cover 4 has an abutting portion 411 abutting against the first pushing portion 51, and the abutting portion 411 has a joint surface adapted to the abutting surface 511. Further, the second pushing portion 52 has a rotation stopping portion 521 thereon, and the rotation stopping portion 521 is configured to limit the rotation of the cover 4 when the cover 4 rotates to the supporting position, so as to maintain the cover 4 at the supporting position. The rotation stop 521 may be a limiting plane, and in this supporting position, the cover 4 and the limiting plane abut against each other, and no rotational torque is applied to the cover 4. More specifically, the second pushing portion 52 is a protruding block with a trapezoidal cross section, however, the second pushing portion 52 may be other structures, such as a protruding block with an arc or fan-shaped cross section, and the limiting plane of the protruding block with a trapezoidal cross section can have a more reliable rotation stopping effect on the cover 4 when in use, so that the method becomes a preferred mode of the present embodiment. In addition, in practice, the guiding chute 7 limits the extension length of the sheet tray 3 by limiting the sliding operation portion 8 at two positions, and limits the sheet tray 3 so that the cover 4 can only be turned to the supporting position, thereby making the limiting more reliable.

Referring to fig. 2, in this embodiment, a torsion spring 6 is further disposed between the cover 4 and the box 2, the torsion spring 6 is wound around the outer side of the shaft body of the pivot 25, one end of the torsion spring is connected to the cover 4, the other end of the torsion spring is connected to the box 2, the torsion spring 6 is used for resetting the cover 4, and as the sheet tray 3 is retracted into the accommodating space of the box 2, the cover 4 is gradually reset to the closed position from the supporting position, so that the sheet tray 3 can be quickly accommodated.

Preferably, the front end of the sheet tray 3 has a avoiding groove 32, when the cover 4 is turned to the open position, the abutting portion 411 can pass through the avoiding groove 32, and the cover 4 is gradually turned to the lower side of the sheet tray 3 and limited by the bottom wall of the sheet tray 3, so as to prevent the cover 4 from retreating to the original position, and at this time, the cover 4 is obliquely disposed with respect to the sheet tray 3. In the supporting position, the cover 4 is vertically disposed with respect to the case 2, and at this time, the bottom end of the cover 4 is supported on the supporting surface, and the top end of the cover 4 is used for supporting the case 2.

In addition, in the present embodiment, the cover 4 includes a cover 41 for closing the lateral opening 21 and a pivoting arm 42 for pivoting the box 2, the first pushing portion 51 is adapted to abut against the cover 41, and the second pushing portion 52 is adapted to abut against the pivoting arm 42. Preferably, the pivoting arm 42 is engaged on the cover 41 in a substantially vertical manner, the pivoting arm 42 has a coupling end for coupling with the cover 41 and a free end, said second pushing portion 52 is adapted to abut against the free end of said pivoting arm 42, said abutment 411 being engaged on the cover 41.

Embodiment two:

referring to fig. 8 to 15, the present embodiment has the same basic structure as the first embodiment. The difference between them is that, on the one hand, the pivot hole is provided at a position remote from the bottom wall of the case 2, for example, at a position close to the upper end opening of the placement groove. At this time, when the cover 2 is at the supporting position, the sheet cassette 1 occupies less space in the height direction, that is, the cassette 2 is at a lower height position than in the first embodiment. However, at this time, since the cover 4 needs to be turned over across the front end side of the sheet tray 3 first during the extension of the sheet tray 3, and the first pushing portion 51 is easily disengaged from the abutting portion 411 after the short-time contact with the abutting portion 411, the cover 4 is not turned over yet to the position where the lower side of the sheet tray 3 is restrained by the bottom wall of the sheet tray 3.

Thus, in connection with fig. 11 to 14, which show the process of turning the cover 4 from the closed position to the supporting position, wherein the arrow S1 shows the turning direction of the cover 4, fig. 15 is a schematic structural view of the sheet tray 3, the present embodiment is different from the first embodiment in another point that the pushing structure 5 in the present embodiment further includes: a third pushing portion 53 adapted to push the cover 4 to be turned over to below the sheet tray 3. Wherein the third pushing portion 53 is arranged on a side wall of the sheet tray 3, and the third pushing portion 53 is located between the first pushing portion 51 and the second pushing portion 52 in the protruding direction of the sheet tray 3.

In the present embodiment, the first pushing portion 51 is adapted to abut against the abutting portion 411 of the cover 41, and the second pushing portion 52 and the third pushing portion 53 are adapted to abut against the free end of the pivot arm 42. Here the process of turning the cover 4 has generally three stages. In the first stage, the first pushing portion 51 pushes the cover plate 41 to flip to a position where the front end of the sheet tray 3 is located below, then in the second stage, the third pushing portion 53 pushes the pivoting arm 42 to continue to rotate, so that the cover plate 41 continues to rotate until the cover plate 41 abuts against the lower end of the sheet tray 3, that is, is limited by the stretched sheet tray 3, in the third stage, the inclined pivoting arm 42 abuts against the second pushing portion 52, and the second abutting portion 52 pushes the pivoting arm 42 to continue to rotate until the cover plate 41 is located at a supporting position where the cover plate 41 abuts against the supporting surface and can support the box body 2. Obviously, compared with the first embodiment, the working space in the height direction can be saved when the cover body 4 is at the supporting position, but the pushing structure 5 needs to be additionally provided with a pushing part, and a technician can specifically select one of the two technical schemes according to the requirements of the occasion of using the printer, so that the printer is not limited.

It should be noted that, although only the pushing structure 5 having two or three pushing portions is shown in the present embodiment, four or more pushing structures may be provided according to the length dimension of the sheet tray 3 or the setting of the position of the pivot portion, which are equivalent to the present embodiment. In some embodiments, the pushing structure 5 in this embodiment may also be a push rod hinged between the sheet tray 3 and the cover 4, where the push rod pushes the cover 4 to rotate during the movement of the sheet tray 3, and the above structure forms a motion form similar to a crank block. Of course, these modifications do not depart from the concept of the present application, and the skilled person may choose to use the present embodiment according to the characteristics of the pushing structure 5 in different forms, which is not described in detail in this embodiment.

In summary, in the above-described embodiment, the cover 4 for closing the lateral opening 21 is pushed to be turned over to the supporting position by a pushing structure 5 to support the cassette 2, and compared with the conventional scheme, the present embodiment skillfully uses the cover 4 as the supporting structure without separately manufacturing and assembling the supporting member for supporting the cassette 2, thereby effectively reducing the production cost of the sheet cassette. In addition, the cover 4 in the present embodiment is provided laterally to the cassette 2 and is hinged to the cassette 2 without damaging the structures of the sheet tray 3 and the cassette 2, so that the structural strength of the sheet cassette 1 is improved.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
