Referring to fig. 1, the components of the printer of the POS device in this example are shown. As can be seen, the POS device printer in this example is mainly composed of a housing 10, a printer body 20, a paper deck cover 30, a button 40, and a printer handle 50.

The housing 10 is used to construct the overall external structure of the printer, and the specific structure can be determined according to actual requirements. A printer body 20 seating area is provided in the housing 10.

The printer body 20 is arranged in the shell 10 to form the functional structure of the whole printer, realize data connection with POS equipment and complete printing work.

The printer body 20 is provided with a corresponding paper bin 21 to accommodate printing paper 60. And when mounted in the housing 10, a corresponding front frame 22 is provided at the edge of the paper deck 21, the front frame 22 being connected to the housing 10.

The paper deck cover 30 is rotatably mounted on the printer body 20 with respect to the paper deck 21. The paper bin cover 30 is provided with a printer bracket 31, and the printer bracket 31 can be clamped with the printer body 20 to cover the paper bin 21.

The printer handle 50 is used as a transmission mechanism, and is rotatably disposed on the printer body 20 to drive the printer bracket 31 on the paper compartment cover 30 to separate from the printer body 20.

The button 40 is arranged on the printer body 20 as a driving structure, and is matched with the printer handle 50 to drive the printer handle 50 to move so as to drive the printer bracket 31 on the paper bin cover 30 to be separated from the printer body 20.

In the printer scheme that constitutes from this, by printer body 20 and paper storehouse lid 30, button 40 and printer handle 50 cooperation, realize good printer play paper and quick replacement fiber container.

Wherein, printer support 31 and printer body 20 separation set up on paper storehouse lid 30 for accomplish the joint between paper storehouse lid 30 and the printer body 20, when carrying out the joint with printer body 20 simultaneously, still form effectual spacing fixed to the printing paper 60 of settling in the paper storehouse 21 on the printer body, in order to guarantee to beat printing paper 60 and enter into printer body 20 in continuity and the reliability.

As shown in fig. 2, the printer handle 50 in this example is provided on the printer body 20 integrally therewith, and drives the printer frame 31 away from the printer body 20.

The printer handle 50 in this example comprises a handle body 51 provided with a drive handle 52 at one end and a drive lug 53 at the other end. The handle body 51 has a plate-like structure as a whole, and the specific shape is determined according to actual requirements.

A driving handle 52 is provided on the top of the handle body 51, and the driving handle 52 is vertically provided on the top side of the handle body 51 for abutting engagement with the push button 40.

A driving lug 53 extends outwards from the side edge of the bottom of the handle body 51, and the driving lug 53 and the handle body 51 form a corner structure. The side surface of the drive projection 53 can be brought into abutting engagement with the printer holder 31.

The printer handle 50 with the structure is rotatably arranged on the printer body 20 through the rotating pin 54 at the corner, and the specific arrangement position enables the driving handle 52 on the printer handle to be in butt fit with the button 40 in a normal state, and simultaneously enables the driving lug 53 to be in butt fit with the printer support 31 buckled on the printer body 20.

On the basis, the embodiment is further provided with a return device inside the printer handle 50, so that the handle 50 can return to the initial position under the action of an internal return spring after moving. For the return means, a return spring is preferred in this example.

Referring to fig. 3, the printer handle 50 is rotatable about a rotation pin 54 to form a lever structure, and when rotated, the top end of the lever structure can drive the driving handle 52 to swing in the area a; in the initial state, the printer handle 50 is under the action of the internal return spring, so that the driving lug 53 at the bottom end is in contact fit with the printer bracket 31 buckled on the printer body 20.

Thus, when the driving handle 52 is forced to swing downwards in the area a, under the action of the lever principle, the driving protrusion 53 at the bottom end of the printer handle 50 moves towards the printer support 31, and because the driving protrusion 53 at the bottom end of the printer handle 50 is in contact with the printer support 31 (as at the position b), the printer handle 50 provides an upward acting force for the printer support 31, so that the printer support 31 moves upwards and then breaks away from the printer body 20, and the paper bin cover 30 breaks away from the printer body 20, so that the covered paper bin is exposed, and the printing paper 60 is replaced.

After the movement is finished (i.e., after the printer is opened), the return rotation is performed by the return spring inside the printer handle 50 to return to the initial position.

In this driving structure, the release force of the paper bin cover 30 is very large, which causes the paper bin cover 30 to pop open rapidly, and in this embodiment, the paper bin cover 30 with a buffering structure is used to overcome this problem.

Referring to fig. 4, a schematic view of the structure of the paper deck lid 30 given in this example is shown. The paper deck cover 30 includes a cover 32 and a connecting bracket 33 provided on the cover 32.

As can be seen from the figure, the cover 32 is preferably a square structure, the front surface of the cover is matched with the shape of the housing, the back surface of the cover is provided with a plurality of reinforcing plates 34 distributed in an array, and the reinforcing plates 34 distributed in the array are distributed at the middle lower position of the cover 32, so that the strength of the whole cover 32 can be improved, and meanwhile, the reinforcing plates 34 are matched with each other to form a limiting component, so as to effectively limit the printing paper 60 placed in the paper bin 21 on the printer body, and ensure the reliability of the placement of the printing paper 60 in the paper bin 21.

For this purpose, the top of the reinforcing plates 34 arranged in an array are provided with circular arc grooves for matching with the printing paper 60.

The upper region of the cover 32 is provided with a plurality of reinforcing plates 35 distributed at equal intervals, and the reinforcing plates 35, besides improving the strength of the cover 32, cooperate with each other to form a mounting region of the printer bracket 31 for mounting and fixing the printer bracket 31 and forming a stable support for the printer bracket 31.

The cover 32 is provided at a bottom thereof with a connecting bracket 33 for connecting with the printer body 20 and allowing the cover 32 to be opened and closed with respect to the paper deck 21 of the printer body 20.

As can be seen, the connecting bracket 33 is mainly formed by two V-shaped connecting brackets which are mutually matched and are symmetrically arranged at the bottom of the printer body 20, wherein the top end of the first arm of each V-shaped connecting bracket is vertically arranged at the bottom of the back surface of the printer body, so that the V-shaped connecting brackets extend outwards in a barb shape relative to the whole printer body 20; meanwhile, the end of the second arm of each V-shaped connecting frame is provided with a connecting rotating pin 37 for connecting with the printer body 20, and the second arm is also provided with a fixing member 36 for arranging a buffer device.

Referring to fig. 5, the damping device is preferably a V-shaped torsion spring 70, and the V-shaped torsion spring 70 is integrally formed and includes a bottom coil portion 71 and

torsion arms

72 and 73 extending outward from both ends of the coil portion 71, wherein the torsion arms 72 and the torsion arms 73 are distributed in a V-shape.

For example, when the V-shaped torsion spring 70 is in the α 0 state between the torsion arm 72 and the torsion arm 73, the torsion spring is in the natural pre-tightening state; and the state between the torque arm 72 and the torque arm 73 is alpha 1, and the torsion spring is in the working state.

The torsion springs 70 thus constructed are respectively disposed on the V-shaped link frames 33 and are connected to the printer body 20 or the housing 10 to buffer the disengaging movement of the cover 32.

Specifically, the coil portion 71 of each torsion spring 70 is fitted over the connecting pivot 37 at the top end of the corresponding V-shaped connecting frame 33, while the torsion arm 72 is fixed to the second arm of the V-shaped connecting frame by the fixing member 36, and the torsion arm 73 is connected to the printer body 20 or the housing 10.

The torsion spring thus disposed on each V-shaped link bracket 33 can effectively cushion the opened state of the paper deck cover 30 with respect to the printer body 20. Break away from printer body 20 at paper storehouse lid 30, when outwards rotating at a high speed around printer body 20 through V-arrangement link 33 and flicking, pivoted V-arrangement link 33 then drives the motion of torque arm 72 on the torsional spring towards torque arm 73, to alpha 1 state, will compress torsional spring 70 this moment, the torsional spring 70 of compressed then forms the elastic restoring force, this process will effectively offset the outside high rotational power of paper storehouse lid 30, thereby form effectual buffering to the open mode of paper storehouse lid 30, prevent that paper storehouse lid is rapid outside motion from touchhing other structures and causing the product life to become low.

In addition, when the paper bin cover 30 moves towards and is fastened with the printer body 20, the rotating V-shaped connecting frame 33 drives the torsion arm 72 on the torsion spring to move back to the torsion arm 73, and the torsion spring 70 returns to the natural pre-tightening state at the moment.

On this basis, in order to effectively drive the printer handle 50 to rotate, so as to control the fastening state between the paper deck cover 30 and the printer body 20, and improve the convenience of the whole printer operation, in this example, the button 40 is embedded in the printer body 20 by a resettable structure, and drives the driving handle 52 on the printer handle 50 by moving in the radial direction facing the printer body 20.

Referring to fig. 1 and 6, the push button 40 in this example is effective to drive the printer handle 50 to rotate by forming an automatically resettable drive assembly with a return spring 80, and automatically restores to the original state after the driving operation is completed.

The push button 40 is mainly composed of a push button body 41, a guide rod 42, a driving plate 43 and a buckle 44 which are mutually matched.

The top of the button body 41 is provided with a pressing surface which is used as a pressing force bearing area to receive driving force applied by the outside and transmit the driving force to the button body 41; meanwhile, the pressing surface on the top of the button body 41 can be integrated with the outer shape of the shell when the button 40 is in a non-working state. The specific structure of the button body 41 can be determined according to actual requirements, and a square structure is adopted here. The button body 41 thus constructed is integrally inserted into the button seating region 23 formed in the printer body 20 and is radially movable therein.

A guide bar 42 is provided at the bottom of the button body for guiding the progress of the operation of the button 40. The guide rod 42 is preferably cylindrical and provides the bottom end of the button body; in order to match the guide rod 42, the bottom of the button placing region 23 on the printer body 20 is provided with a corresponding guide hole 24 (see fig. 7), so that when the button body 41 is inserted into the button placing region 23, the guide rod 42 thereon is just inserted into the guide hole 24 at the bottom of the button placing region 23 and is matched with the guide hole 24, and effective guide is formed for the movement of the button body 41 in the button placing region 23.

At the same time, the guide rod 42 also serves as a seating part of the return spring 80, so that the return spring 80 can form an elastic restoring force to the button body 41. Specifically, the return spring 80 is integrally sleeved on the guide rod 42, one end of the return spring abuts against the end portion of the bottom end of the button body, and the other end of the return spring abuts against the bottom of the button installation region 23 (see fig. 7) of the button 40 formed on the printer body 20, so that when the button 40 moves radially, the return spring 80 can be compressed, and then the return spring 80 forms the restoring force for restoring the driving button 40.

The buckle 44 is disposed at a side portion of the button body 41, and is used for movably limiting the button body in a button mounting area formed on the printer body 20, so as to prevent the button body 41 from being separated from the button mounting area on the printer body 20. The specific structure of the latch 44 can be determined according to actual requirements.

The driving plate 43 is correspondingly disposed on a side portion of the button body 41, and when the button body 41 is in an initial state, the driving plate 43 is in driving connection with the driving handle 52 on the printer handle 50, and can drive the printer handle 50 to rotate when moving along with the button body. The specific structure of the driving plate 43 may be determined according to actual requirements, as long as the printer handle 50 can be effectively driven to operate when the driving plate moves in the radial direction along with the button body 41.

The POS device printer (as shown in fig. 7) formed based on the scheme drives the printer handle 50 to rotate through the button 40 with the automatic reset function, and then the printer handle 50 rotates to drive the paper bin cover 30 to be separated from the printer body 20, so that the paper bin is exposed, and the paper bin is replaced quickly; when the paper storehouse lid 30 breaks away from printer body 20, through buffer greatly reduce the speed and the range that the paper storehouse lid 30 outwards bounced open for printer body 20, effectively prevent that the quick return motion of paper storehouse lid from touchhing other structures and causing the product life to step down, improve the use of whole product simultaneously and experience.

Referring to fig. 7-9, there are shown schematic views of the POS device printer in an initial state in this example.

As can be seen, when the POS device printer is in the initial non-open state, the button 40 thereon is in the initial position under the action of the return spring 80.

The paper bin cover 30 is fastened on the printer body 20 through the printer support 31 on the paper bin cover, covers the paper bin on the printer body 20, and effectively limits and fixes printing paper 60 in the paper bin.

The printer handle 50 on the printer body 20 is in an initial state, the top end of the printer handle is in fit connection with the button 40, and the bottom end of the printer handle is in direct fit connection with the printer bracket 31 buckled on the printer body 20.

At this time, the torsion spring 70 on the paper compartment cover 30 is located at the original position, and the torsion spring 70 is not stressed temporarily.

Reference is now made to fig. 10-12, which illustrate the POS device printer in this example as it would appear with the cover of the hopper open.

As can be seen, when the paper compartment cover on the printer needs to be opened, the button 40 is pressed, and is forced to move to the working position in the radial direction, the process compresses the return spring 80, and simultaneously pushes the top end of the printer handle 50 to rotate, so that the bottom end of the printer handle 50 moves towards the printer support 31, the printer handle 50 generates a pushing force towards the printer support 31, and the printer support 31 is driven to be separated from the printer body 20; when the printer bracket 31 is separated from the printer body 20, the paper bin cover 30 generates a certain tripping force, and the tripping force drives the paper bin cover 30 to be separated from the printer body 20.

Meanwhile, when the paper compartment cover 30 is driven to separate from the printer body 20, the torsion spring 70 on the paper compartment cover is immediately compressed to be in a working state, and at the moment, the torsion spring receives a tripping force on the printer, so that the separating state of the paper compartment cover 30 is buffered, and the paper compartment cover is prevented from bouncing outwards and rapidly.

Referring to fig. 13-15, the fully open position of the cover of the hopper in the POS device printer of the present example is shown.

In this state, the return spring 80 inside the printer body 20 will bring the button 40 back to the initial position, and the button 40 will bring the printer handle 50 back to the initial position while the button 40 returns to the initial position.

Because the tripping force that the upper paper storehouse cover of printer received is great, printer support 31 and paper storehouse cover 30 open as an subassembly fast, and torsional spring 70 on the paper storehouse cover also works completely (compressed to the biggest promptly) here simultaneously, prevents that the paper storehouse cover subassembly from touchhing the following structure, will vibrate impact energy and release fast, has made things convenient for customer experience.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
