Detailed Description

In the claims and in the description, unless otherwise defined, the terms "first," "second," or "third," etc., are used for distinguishing between different objects and not for describing a particular sequential order.

In the claims and the specification, unless otherwise defined, the terms "center", "lateral", "longitudinal", "horizontal", "vertical", "top", "bottom", "inner", "outer", "upper", "lower", "front", "rear", "left", "right", "clockwise", "counterclockwise", etc., refer to an orientation or positional relationship based on that shown in the drawings, and are merely for convenience of description, and do not imply that the devices or elements referred to must have a particular orientation or be constructed and operated in a particular orientation.

In the claims and specification, unless otherwise defined, the terms "fixedly coupled" and "fixedly connected" are to be construed broadly as any manner of connection without a displacement relationship or relative rotational relationship therebetween, and that is to say include non-detachably fixedly connected, integrally connected, and fixedly connected by other means or elements.

In the claims and specification, unless otherwise defined, the terms "comprising," having, "and variations thereof mean" including but not limited to.

In the claims and the description, unless otherwise defined, the term "provided" means that the technical feature located thereafter is a part of the technical feature located before it.

In the claims and the specification, unless otherwise defined, the term "elastic clamping" refers to that in the process of establishing the clamping by relative movement between the two, at least one of the two is forced to deform by abutting each other until the deformation is recovered after the clamping is established, and the two cannot be separated from each other in a direction deviating from the original movement direction. Typically, such abutments employ ramped abutments such that the deformation is perpendicular to the direction of movement, so as to avoid each other to allow movement to continue. Generally, after the snap-fit is established and deformation is restored, they are brought into surface contact with each other to prevent disengagement.

In the claims and specification, unless otherwise defined, the term "rotation-stopping fit" refers to a fit between the two that cannot rotate relative to each other, typically by non-rotating face fit. Of course, the anti-rotation fit also includes a fixed connection.

The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 20 and 21, the lower case 16 is positioned in front of the lower case support portion 20 and the lower case stopper portion 21 is positioned in front of the lower case stopper portion 31 with respect to the outer case 14 in both the lower case support portion 30. As shown in fig. 22 and 23, the lower case 16 is positioned above and forward of the upper case stopper portion 26 with respect to the upper case 15, and the upper case stopper portion 29.

Referring to fig. 24-33, fig. 24-33 illustrate the lower shell 16 slid into position relative to the outer shell 14 in a front-to-back direction. As shown in fig. 24, when the lower housing 16 is slid into place, the lower housing 16 closes the opening 35 of the mounting cavity 34. As shown in fig. 25 to 28, when the lower case 16 is slid into place, the lower case support part 20 supports the lower case support part 30 upward so that the lower case 16 cannot move downward with respect to the outer case 14. As shown in fig. 28, in the sliding process of the lower case 16, the lower case stopper 31 is pushed forward against the front surface of the lower case stopper 21, so that the lower case 16 is deformed downward, or the lower case stopper 21 may be deformed upward, or both of them; after the lower shell limiting part 31 passes, the lower shell 16 and/or the lower shell retaining part 21 recover to deform, the lower shell retaining part 21 and the lower shell limiting part 31 establish a clamping relationship, and the lower shell retaining part 21 limits the lower shell limiting part 31, so that the lower shell 16 cannot withdraw forwards relative to the outer shell 14. As shown in fig. 29 and 30, when the lower case 16 is slid into place, the lateral stopper portions 23 on both sides of the outer case 14 respectively abut against the lower case 16 inward, so that the lower case 16 cannot move laterally relative to the outer case 14. As shown in fig. 31 to 33, when the lower case 16 is slid in place, the upper case stopper portions 29 are respectively located above the upper case stopper portions 26, and the upper case stopper portions 29 are positioned to stop the upper case stopper portions 26, so that the upper case 15 cannot be withdrawn upward. To this end, the housing 14, the upper case 15, and the lower case 16 are firmly connected together, and the printer core 3 is firmly fixed between the housing 14 and the upper case 15, the circuit board 4 is accommodated in the mounting chamber 34, and the opening 35 of the mounting chamber 34 is closed by the lower case 16.

Referring to fig. 34 to 36, fig. 34 to 36 illustrate the insertion of the front case 17 into the housing 14 in a top-down direction. As shown in fig. 34, when the front case 17 is inserted in place, the front case 17 closes the gap 36 between the printer core 3 and the housing 14, and a detachment port 37 between the front case 17 and the upper case 15 is formed at the position of the notch 33 of the front case 17, and the function of the detachment port 37 is described in detail in the detachment process. As shown in fig. 35 and 36, during the insertion of the front case 17, the front case stopper portion 32 abuts downward against the claw top surface of the front case stopper portion 28, deforming the front case stopper portion 28 rearward until the front case stopper portion 32 returns to its deformed state by the rear front case stopper portion 28, the front case stopper portion 28 and the front case stopper portion 32 establish a snap-in relationship, and the front case stopper portion 28 limits the front case stopper portion 32, so that the front case 17 cannot be withdrawn upward.

The following describes the process of removing the printer housing 12 in steps.

First, the front case stopper 28 is pushed backward by a tool through the dismounting port 37, the front case stopper 28 is disengaged from the front case stopper 32, and the front case 17 is pulled out from the bottom to the top.

Then, the lower case stopper 21 or the lower case 16 is deformed by a tool through the gap 36, the lower case stopper 21 is disengaged from the lower case stopper 31, and the lower case 16 is pulled out from the rear to the front, and at this time, the upper case stopper 29 no longer restricts upward movement of the upper case 15.

Finally, the two side walls of the housing 14 are forced to be opened outwards, so that the housing clamping part 22 is separated from the upper housing clamping part 27, and then the upper housing 15 is withdrawn from the bottom upwards.

To this end, the front case 17, the lower case 16, and the upper case 15 are all separated from the housing 14, and the printer core 3 and the circuit board 4 can be detached.

Referring to fig. 37 to 39, fig. 37 to 39 show the printer 1 when the printer cover 13 is rotated to the closed position relative to the printer housing 12. As shown in fig. 2, the printer cover 13 is configured to house the feed roller assembly 2, and the printer cover 13 is adapted to rotate relative to the printer housing 12 between a closed position and an open position. As shown in fig. 38, the printer cover 13 is rotatably connected to the top end of the upper case 15, and when the printer cover 13 is rotated to the closed position, a receiving chamber 38 for receiving the printing material 39 is formed between the printer cover 13 and the upper case 15. As shown in fig. 2, when the printer cover 13 is rotated to the open position, the receiving chamber 38 is opened and the printing material 39 is adapted to be removed or placed for replacement. As shown in fig. 38, when the printer cover 13 is rotated to the closed position, the transmission gear 7 is engaged with the output gear of the gear train 11, so that the driving member 10 can drive the platen roller 6 to rotate through the gear train 11 and the transmission gear 7. As shown in fig. 39, when the printer cover 13 rotates to the closed position, the paper feeding roller 6 is in press fit with the heating member 7, so that when the paper feeding roller 6 drives the printing material 39 to move by friction force, the heating member 7 can selectively heat the printing material 39, thereby realizing paper feeding and printing functions. It can also be seen from fig. 39 that the circuit board 4 is fixed in the accommodation chamber 34.

From the above description of the first embodiment, it is known that:

In the present embodiment, the housing 14 is provided with a deck support portion 18 for supporting the printer deck 3 upward and forward, and the upper case 15 is provided with a deck limit portion 24 for limiting the printer deck 3 to prevent upward and forward movement of the printer deck 3, so that the printer deck 3 can be fixed; the upper shell 15 and the outer shell 14 form a mounting cavity 34 for accommodating the circuit board 4 electrically connected with the printer core 3, so that the purpose of accommodating the printer core 3 and the circuit board 4 by the printer shell 12 is realized.

In this embodiment, after the upper shell 15 is inserted into the outer shell 14 downward, the upper shell 15 is limited by the upper shell stopping portion 29 of the lower shell 16 to move upward, so that the upper shell 15 cannot withdraw from the insertion direction; the lower shell 16 slides relative to the outer shell 14 and is supported by the lower shell support 20 after sliding into place so that the lower shell 16 cannot be withdrawn downwardly. Therefore, the printer housing 12 in the present embodiment can be assembled by only the insertion and sliding actions, improving the assembly efficiency.

In this embodiment, the lower shell retaining portion 21 of the outer shell 14 is elastically clamped with the lower shell limiting portion 31 to limit the movement of the lower shell 16 in a direction away from the sliding direction, so that the lower shell 16, the upper shell 15 and the outer shell 14 are in a firmer connection relationship.

In this embodiment, the front case 17 can be assembled by the insertion method as well, thereby improving the assembly efficiency. The front shell retaining portion 28 is elastically clamped with the front shell limiting portion 32 to limit the front shell 17, so that the front shell 17 is prevented from being withdrawn from the insertion direction, and the assembly is firmer.

In this embodiment, the front shell 17 and the upper shell 15 form the disassembly opening 37, so that the front shell stopping portion 28 is conveniently forced to deform by a tool, thereby realizing the quick disassembly effect. In this embodiment, the gap 36 covered by the front case 17 can force the deformation of the lower case 16 and/or the lower case retaining portion 29 to release the locking, thereby achieving the quick-release effect on the lower case 16.

In this embodiment, the upper case 15 is further firmly connected to the housing 14 by the engagement of the housing engagement portion 22 and the upper case engagement portion 27. The lateral restraint 23 of the housing 14 further restrains the lower shell 16 laterally, facilitating a secure connection to the overall printer housing 12.

In this embodiment, the printer cover 13 is opened and closed by rotation, and the printing material 39 can be easily attached and detached and replaced.

In this embodiment, although the paper feeding roller 6 is mounted on the printer cover 13, the driving part of the paper feeding roller 6 is mainly concentrated in the printer housing 12, so as to avoid the dispersion of mechanical structures, and thus, the intensive design is facilitated, the size of the printer 1 is reduced, and the printer is convenient to hold.

Example two

The second embodiment is different from the first embodiment in that in the present embodiment, the upper case stopper portion 29 located in the middle of the lower case 16 is supported upward by the upper case stopper portion 26, so that the upper case 15 can support the lower case 16 to prevent the lower case 16 from moving downward. At the same time, the upper case stopper 29 limits the upper case stopper 26 to prevent the upper case 15 from moving upward, so that the upper case 15 cannot be withdrawn away from the insertion direction. In the present embodiment, the lower case support parts 20 limit the lower case support parts 30 at both ends of the lower case 16 in the front-rear direction to prevent the lower case support parts 30 from moving downward.

In this embodiment, the upper case stopper 29 is supported by the upper case stopper 26, so that the lower case 16 cannot move downward; the upper case 15 cannot be withdrawn upward by the upper case stopper portion 26 being restricted by the upper case stopper portion 29. Thus, interlocking of the upper case 16 and the lower case 16 is achieved. Since assembly can be achieved also by only the insertion and sliding actions, assembly efficiency is also improved.

In the present embodiment, the lower case support parts 30 at both ends of the lower case 16 in the front-rear direction are restrained from moving downward by the lower case support parts 20, so that in use, both ends of the lower case 16 in the front-rear direction do not form a gap with the outer case 14; the upper case stopper 29 is located at the middle of the lower case 16 in the front-rear direction, and thus the support of the upper case stopper 26 prevents the middle of the lower case 16 in the front-rear direction from collapsing downward.

Example III

Referring to fig. 40 and 41, fig. 40 and 41 show the printer housing 12 in the present embodiment. As shown in fig. 40 and 41, the present embodiment differs from the first embodiment in that the housing 14 is no longer provided with the lower-housing stopper 21, but instead the front housing 17 is provided with the lower-housing stopper 40 extending downward. The lower case stopper 40 limits the lower case stopper 31 when the front case 17 is inserted in place, so that the lower case 16 cannot be withdrawn forward from the rear with respect to the outer case 14, specifically, the lower case stopper 40 is provided with a forward limiting surface, and when the lower case 16 is withdrawn forward from the rear, the lower case stopper 31 is limited by the lower case stopper 40.

In this embodiment, the lower shell stopper 40 blocks the lower shell 16 from exiting from the sliding direction when the front shell 17 is inserted in place, so that the elastic clamping relationship between the outer shell 14 and the lower shell 16, which is difficult to be removed, can be avoided, firm connection can be realized faster, and the disassembly is also more convenient.

The above description and examples are illustrative of the scope of the application and are not to be construed as limiting the scope of the application.
