Description

Technical Field

[0001] This utility model relates to the field of printers, specifically to a highly adaptable printer. Background Technology

[0002] Printers are used to print the content required by users. In the catering, shopping mall and other consumer industries, label printers are commonly used to print receipts. Because label printers are used frequently and the printing paper rolls need to be replaced frequently, label printers generally have the paper tray cover set to be easy to rotate and open, so as to facilitate users to replace the printing paper rolls.

[0003] However, different users require different widths of label printing paper rolls. Designing paper trays of different sizes for different widths of printing paper rolls would obviously increase costs and would not meet the needs of users using different sizes of printing paper rolls at once. When users put small-sized printing paper rolls into large-sized paper trays for use, the printing paper rolls are prone to wobbling from side to side, resulting in a sharp drop in printing quality.

[0004] The research objective of this utility model is to design a highly adaptable printer that can stably adapt to printing rolls of paper of different sizes, addressing the problems existing in the prior art. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a highly adaptable printer that can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A highly adaptable printer includes:

[0008] The machine body has a paper tray inside;

[0009] Several adjusting components are disposed inside the paper bin and are movable along the length of the paper bin;

[0010] A primary locking mechanism includes a connector movably mounted on a plurality of the adjusting members and a limiting rod that laterally moves through the plurality of the adjusting members, wherein the connector is used to limit the connection of the limiting rod.

[0011] The secondary locking mechanism includes a limiting structure disposed on the adjusting member and a limiting structure disposed in the paper tray; after moving several of the adjusting members, the adjusting members are locked by the engagement between several connecting members and the limiting rod, and by the limiting structure limiting the limiting structure.

[0012] Furthermore, the adjusting member includes a vertically arranged adjusting part and a sliding part that connects to the lower end of the adjusting part and extends laterally. The restricting structure includes a plurality of locking protrusions protruding on both sides of the sliding part. The bottom of the paper tray is recessed and has a sliding groove. The limiting structure includes limiting protrusions extending towards each other on both sides of the sliding groove opening. The sliding part is laterally slidably disposed in the sliding groove, and the plurality of locking protrusions on both sides are limited and clamped by the limiting protrusions on both sides. After the adjusting member is slid, the adjusting member is locked by the limiting protrusions on both sides clamping and clamping the plurality of locking protrusions on both sides.

[0013] Furthermore, the bottom of the chute is concave in an arc shape, and the sliding part is adapted to the bottom of the chute in an arc shape and includes a sliding ridge and two locking ridges respectively connecting the lower middle side and the two sides of the adjusting part. The bottom of the sliding ridge is provided with a plurality of abutting ridges that extend laterally along the length of the chute and slide against the bottom of the chute. The opposite sides of the two locking ridges are recessed with L-shaped steps. The two steps respectively include a vertical surface and a horizontal surface adapted to the opposite side and bottom side of the two limiting ridges. The locking protrusions are respectively provided on the vertical surface of the two steps.

[0014] Furthermore, the number of the adjusting members is set to two, and the adjusting parts of the two adjusting members are arranged facing each other. The middle of the sliding rib is provided with a transverse elongated hole extending toward the two locking ribs. The middle of the adjusting part is provided with a vertical elongated hole extending vertically and communicating with the transverse elongated hole. The width of the vertical elongated hole gradually increases from top to bottom. The opposite sides of the two adjusting members are provided with two sets of reinforcing ribs connecting the two locking ribs and the two sides of the vertical elongated hole.

[0015] Furthermore, the tops of the two sets of reinforcing ribs are arranged in an upward-facing V-shape, the connector is slidably connected to the adjustment part at the upper and lower limits, the limiting rod passes through the vertical elongated hole laterally, and the lower end of the connector is adapted to the tops of the two sets of reinforcing ribs and is recessed with a groove for interference locking to the outer wall of the limiting rod.

[0016] Furthermore, the restricted structure includes a friction element disposed on the horizontal surface for frictionally abutting the bottom of the limiting protrusion. The limiting structure also includes elastic upper top pieces disposed on both sides of the slide groove and corresponding to the bottom of the two clamping ribs. The bottom of the sliding rib is provided with a plurality of abutting ribs extending laterally along the length of the slide groove. When the adjusting member is pressed down, the friction element disengages from the limiting protrusion, and the plurality of abutting ribs abut against the bottom of the slide groove. The adjusting member can slide laterally. When the adjusting member is released, the two upper top pieces push the adjusting member up until the two clamping ribs abut against the bottom of the limiting protrusion through friction between the two friction elements. The adjusting member is limited.

[0017] Furthermore, the machine body includes a housing and a cover rotatably connected to the housing. The housing has opposite recesses on both sides corresponding to the upper half of the opposite sides of the two adjusting members. The cover and the housing form the paper tray and the paper outlet connected to the paper tray. The paper tray is provided with a printer core for printing on the side corresponding to the paper outlet.

[0018] Therefore, the beneficial effects of this utility model are:

[0019] 1. By adding adjustable parts and setting up primary and secondary locking mechanisms, the printer's paper tray can adjust the installation width by moving several adjustable parts to accommodate different paper sizes, thus improving the printer's adaptability. Furthermore, the primary locking mechanism restricts the relative displacement between the adjustable parts, and the secondary locking mechanism individually restricts the displacement of each adjustable part within the paper tray. This double locking enhances the locking strength of the adjustable parts, reducing the possibility of them loosening in the event of a drop or paper pulling. This ensures high printer adaptability while improving operational stability.

[0020] 2. After the sliding adjustment component is slidable, the limiting protrusions on both sides clamp and lock the adjustment component to several locking protrusions on both sides. This allows the adjustment component to slide when the user pushes it with considerable force. After the user stops pushing, the adjustment component is locked by the clamping protrusions on the locking protrusions. This greatly improves the convenience of adjusting the paper tray width and allows for stepless and arbitrary adjustment of the paper tray width, greatly improving the adaptability of the paper tray to different sizes of printing paper.

[0021] 3. The stability of the adjusting component's sliding is improved by the combination of the stepped part and the limiting protrusion. Furthermore, by designing the sliding part as an arc-shaped concave distribution of sliding ribs and locking ribs, the two locking ribs have a certain amount of small deformation space. This allows the adjusting component to be directly pressed down and locked into the sliding groove during installation, and the adjusting component can be directly removed by turning the knob to disengage it from the sliding groove during disassembly. This greatly improves the convenience of the adjusting component's installation and removal. In addition, the addition of several abutting ribs allows for line contact sliding between the adjusting ribs and the bottom of the sliding groove, improving the smoothness of the adjusting component's sliding and avoiding excessive wear of the adjusting ribs and the occurrence of the adjusting component getting stuck.

[0022] 4. The design of the horizontal and vertical elongated holes allows the adjusting component to have a certain amount of space for slight deformation after being subjected to lateral compression. This makes it easier to remove the adjusting component when disassembling the knob, and avoids the two locking ribs from deforming excessively and breaking. This further improves the ease of disassembly and assembly of the adjusting component. On this basis, the addition of reinforcing ribs increases the overall structural strength of the adjusting component, preventing it from deforming after disassembly and assembly and rendering it unusable, thus extending the service life of the adjusting component.

[0023] 5. By sliding the upper and lower limit of the connector to the adjustment part, the operation range of the adjustment part can be expanded by adding a connector, which would reduce the adjustment width between the adjustment parts and prevent the paper tray from being unable to accommodate some larger printing papers. The sliding down and locking to the limit rod through the slot is convenient and quick, improving the locking convenience of the first-level locking mechanism. With the addition of the clearance groove, even when the two adjustment parts are moved to the maximum distance in opposite directions and both sides abut against the inner wall of the housing, the user can still perform the locking and unlocking operations of the first-level locking mechanism by sliding the connector up and down through the clearance groove, so as to ensure the adjustment range of the adjustment parts and thus ensure the adaptation range of the paper tray.

[0024] 6. The adjustment component is pressed down and locked up by the cooperation of the upper top plate and the friction component, which improves the adjustment convenience of the adjustment component. In addition, by adding several abutting ridges, the adjustment ridges contact and slide with the bottom line of the slide groove after the adjustment component is pressed down, which improves the smoothness of the adjustment component sliding and avoids excessive wear of the adjustment ridges and the occurrence of the adjustment component sliding jamming.

[0033] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0034] Example 1

[0035] refer to Figure 1-5A highly adaptable printer, comprising:

[0036] The machine body 1 has a paper tray 11 inside;

[0037] Several adjusting components 2 are disposed inside the paper bin 11 and are movable along the length direction of the paper bin 11;

[0038] The first-level locking mechanism 3 includes a connector 31 movably disposed on a plurality of the adjusting members 2 and a limiting rod 32 that movably passes through the plurality of the adjusting members 2 laterally. The connector 31 is used to limit the connection of the limiting rod 32.

[0039] The secondary locking mechanism 4 includes a limiting structure on the adjusting member 2 and a limiting structure in the paper tray 11; after moving several adjusting members 2, the limiting rod 32 passes laterally through the middle side roll of the printing paper roll and several adjusting members 2, and then the several adjusting members 2 are locked by the snap-fit ​​between several connecting members 31 and the limiting rod 32, and by the limiting structure limiting the limiting structure.

[0040] The above structure, through the addition of adjusting components 2 and the setting of primary locking mechanism 3 and secondary locking mechanism 4, allows the printer's paper tray 11 to adjust the installation width by moving several adjusting components 2 when facing different paper sizes, thereby adapting to different paper sizes and improving the printer's adaptability. On this basis, the locking of primary locking mechanism 3 can limit the relative displacement between several adjusting components 2, and the locking of secondary locking mechanism 4 can limit the displacement of several adjusting components 2 within paper tray 11. Thus, the double locking enhances the locking strength of adjusting components 2, reducing the possibility of adjusting components 2 loosening in the event of the printer being dropped or the paper being pulled, thereby improving the stability of use while ensuring the printer's high adaptability.

[0041] To improve the ease of adjustment of the adjusting component 2, the adjusting component 2 includes a vertically arranged adjusting part 21 and a sliding part that connects to the lower end of the adjusting part 21 and extends laterally. The limiting structure includes a plurality of locking protrusions 41 protruding on both sides of the sliding part. The bottom of the paper tray 11 is recessed and has a sliding groove 111. The limiting structure includes limiting ribs 42 extending towards each other on both sides of the groove opening of the sliding groove 111. The sliding part is laterally slidably disposed in the sliding groove 111, and the plurality of locking protrusions 41 on both sides are limited and clamped by the limiting ribs 42 on both sides. After the adjusting component 2 is slidable, the adjusting component 2 is locked by the limiting ribs 42 on both sides of the locking protrusions 41. The above structure allows the adjusting member 2 to slide when the user pushes it with considerable force. After the user stops pushing, the adjusting member 2 is locked by the clamping of the locking protrusion 41 by the limiting protrusion 42. This greatly improves the convenience of adjusting the width of the paper tray 11 and enables stepless arbitrary adjustment of the width of the paper tray 11, which greatly improves the adaptability of the paper tray 11 to different sizes of printing paper.

[0042] To improve the ease of assembly and disassembly of the adjusting part 2, the bottom of the groove 111 is recessed in an arc shape. The sliding part is adapted to the bottom of the groove 111 and is recessed in an arc shape, and includes a sliding rib 22 and two locking ribs 23 respectively connecting the lower middle side and the two sides of the adjusting part 21. The bottom of the sliding rib 22 is provided with a plurality of abutting ribs 222 that extend laterally along the length of the groove 111 and slide against the bottom of the groove 111. The opposite sides of the two locking ribs 23 are recessed with L-shaped steps. The two steps include a vertical surface 231 and a horizontal surface 232 adapted to the opposite side and bottom side of the two limiting ribs 42, respectively. The locking protrusions 41 are respectively protruded on the vertical surface 231 of the two steps. The above-mentioned structure improves the stability of the sliding of the adjusting component 2 through the cooperation of the stepped part and the limiting protrusion 42. Furthermore, by setting the sliding part as an arc-shaped concave distribution of sliding ribs 22 and locking ribs 23, the two locking ribs 23 have a certain small deformation space, so that the adjusting component 2 can be directly pressed down and locked into the slide groove 111 during installation, and the adjusting component 2 can be directly removed by turning the knob out of the slide groove 111 during disassembly, which greatly improves the convenience of the adjusting component 2 in disassembly and assembly. In addition, by adding several abutting ribs 222, the adjusting ribs and the bottom of the slide groove 111 slide in line contact, which improves the smoothness of the sliding of the adjusting component 2 and avoids excessive wear of the adjusting ribs and the occurrence of the adjusting component 2 getting stuck.

[0043] To further improve the ease of assembly and disassembly of the adjusting component 2, two adjusting components 2 are provided. The adjusting parts 21 of the two adjusting components 2 are arranged facing each other. The middle of the sliding rib 22 is provided with a transverse elongated hole 221 extending toward the two locking ribs 23. The middle of the adjusting part 21 is provided with a vertical elongated hole 211 extending vertically and communicating with the transverse elongated hole 221. The width of the vertical elongated hole 211 gradually increases from top to bottom. The opposite sides of the two adjusting components 2 are provided with two sets of reinforcing ribs 24 connecting the two locking ribs 23 and the two sides of the vertical elongated hole 211. The above structure, through the setting of the transverse elongated hole 221 and the vertical elongated hole 211, allows the adjusting component 2 to have a certain space for slight deformation after being subjected to transverse compression. This makes it easier to remove the adjusting component 2 when disassembling the knob, and can prevent the two locking ribs 23 from deforming excessively and breaking. This further improves the convenience of disassembling and assembling the adjusting component 2. On this basis, by adding reinforcing ribs 24, the overall structural strength of the adjusting component 2 is improved, preventing the adjusting component 2 from deforming after disassembly and assembly and becoming unusable again, thus extending the service life of the adjusting component 2.

[0044] To improve the ease of locking the primary locking mechanism 3, the tops of the two sets of reinforcing ribs 24 are arranged in an upward-opening V-shape. The connecting piece 31 is slidably connected to the adjusting part 21 with upper and lower limits. Specifically, the connecting piece 31 and the adjusting part 21 are slidably connected with upper and lower limits through a protrusion 311 and a groove 212. The limiting rod 32 passes horizontally through the vertical elongated hole 211. The lower end of the connecting piece 31 is adapted to the top of the two sets of reinforcing ribs 24 and is recessed with a slot 312 for interference fit to the outer wall of the limiting rod 32. The above structure, by slidably connecting the connecting piece 31 to the adjusting part 21 with upper and lower limits, avoids the expansion of the operating range of the adjusting part 2 by adding the connecting piece 31, which would reduce the width of the adjustment between the adjusting parts 2, causing the paper tray 11 to be unable to accommodate some larger printing papers. Furthermore, the locking method of sliding down and interfering with the limiting rod 32 through the slot 312 is convenient and quick, improving the ease of locking the primary locking mechanism 3.

[0045] Specifically, the body 1 includes a housing 12 and a cover 13 rotatably connected to the housing 12. The housing 12 has recessed grooves 121 on opposite sides corresponding to the upper halves of the opposite sides of the two adjusting members 2. A paper tray 11 and a paper outlet 14 connecting the paper tray 11 are formed between the cover 13 and the housing 12. A printer core 15 for printing is provided on one side of the paper tray 11 corresponding to the paper outlet 14. Thus, by adding the recessed grooves 121, even when the two adjusting members 2 are displaced to their maximum distance and their opposite sides abut against the inner wall of the housing 12, the user can still perform locking and unlocking operations of the primary locking mechanism 3 through the sliding connecting piece 31 of the recessed grooves 121, ensuring the adjustment range of the adjusting members 2, and thus ensuring the adaptability range of the paper tray 11.

[0046] Example 2

[0047] refer to Figure 6-8 While the method of deformation clamping and locking by using the clamping protrusion 41 and the limiting protrusion 42 can improve locking stability, prolonged clamping can easily cause the clamping protrusion 41 to wear and loosen. Since the clamping protrusion 41 is part of the adjusting component 2, it is difficult to repair. Therefore, the difference between this embodiment and Embodiment 1 is as follows:

[0048] The technical solution of replacing the clamping protrusion 41 with a friction element 43 is specifically defined as follows: the limiting structure includes a friction element 43 disposed on the transverse surface 232 and used for frictional abutment against the bottom of the limiting protrusion 42; the limiting structure also includes elastic upper top pieces 44 disposed on both sides of the sliding groove 111 and corresponding to the bottom of the two clamping protrusions 23; the bottom of the sliding protrusion 22 is provided with a plurality of abutment protrusions 222 extending laterally along the length direction of the sliding groove 111; specifically, the upper top piece 44 can be an iron sheet. The structure includes a metal spring; the addition of friction element 43 and upper top plate 44 allows the adjusting element 2 to slide laterally when pressed down, as the friction element 43 disengages from the limiting protrusion 42 and several abutting ribs 222 abut against the bottom of the sliding groove 111. When the adjusting element 2 is released, the two upper top plates 44 push the adjusting element 2 until the two locking ribs 23 abut against the bottom of the limiting protrusion 42 through friction between the two friction elements 43, thus limiting the adjusting element 2. The cooperation of the upper top plate 44 and friction element 43 enables the adjusting element 2 to slide downwards and lock upwards, improving the ease of adjustment. Furthermore, the addition of several abutting ribs 222 ensures that the adjusting ribs contact and slide against the bottom of the sliding groove 111 after the adjusting element 2 is pressed down, improving the smoothness of the sliding and preventing excessive wear of the adjusting ribs and jamming of the adjusting element 2.

[0049] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
