Abstract
Description
Technical Field
[0001] This application relates to the field of printing equipment technology, and more particularly to a locking component, a mechanism, and a printer. Background Technology
[0002] A wire marking machine is a printer that uses thermal transfer printing technology to print characters on consumables such as sleeves and stickers. In some existing thermal transfer printers, the ribbon cartridge and sleeve are first installed inside the printer. The printer's transmission mechanism drives the new ribbon in the cartridge to align with the consumable, and then the thermal transfer technology quickly and clearly transfers the transfer medium from the ribbon to the surface of the sleeve.
[0003] In related technologies, ribbon cartridges need to be locked in place by locking mechanisms to ensure reliable installation. However, existing locking mechanisms do not provide the expected fixation for the ribbon cartridges, and even when locked, the cartridges may wobble. Worse still, in the event of a printer impact, the locking mechanism can easily detach from the cartridge, causing the cartridge to fail to hold properly and consequently affecting the printer's printing accuracy. Utility Model Content
[0004] The purpose of this application is to provide a locking component, a mechanism, and a printer to solve the aforementioned technical problems existing in the prior art.
[0005] In a first aspect, this application provides a locking assembly for use in a printer. The locking assembly includes a carrier, a locking member, and an elastic member. The carrier has a guide member, and the locking member is movably engaged with the guide member. The guide member guides the locking member to move along a first direction to switch between a locked position and an unlocked position. When the locking member is in the locked position, the locking member limits and locks the ribbon cartridge. When the locking member is in the unlocked position, the locking member releases the locking of the ribbon cartridge. One end of the elastic member is connected to the locking member, and the other end of the elastic member is connected to the carrier. The extension direction of the elastic member has an angle with the first direction.
[0006] Secondly, this application provides a movement that includes a locking component as described in the first aspect.
[0007] Thirdly, this application provides a printer that includes the mechanism described in the second aspect.
[0008] The technical solution adopted in this application can achieve the following beneficial effects:
[0009] In the locking assembly disclosed in this application, the carrier is provided with a guide, and the locking member can cooperate movably with the guide to guide the locking member to move along a first direction, thereby switching the locking member between a locked position and an unlocked position and preventing the locking member from deviating from the preset trajectory and failing to lock the ribbon cartridge. During this period, an elastic member can drive the locking member to switch from one of the locked position to the other, and the extension direction of the elastic member has an angle with the first direction. This allows the elastic member to generate a component force in a second direction, and the first and second directions intersect. The component force of the elastic member in this application can drive the locking member to move, so that the locking member and the guide member abut against each other in the second direction. The component force can reduce the amplitude of the left and right swaying of the locking member during movement, and the movement stability of the locking member is better. The locking member can be inserted more accurately into the locking hole of the ribbon cartridge, improving the installation stability of the ribbon cartridge.
[0010] Compared to related technologies, in this application, the cooperation between the elastic element and the locking element improves the movement stability of the locking element. This avoids severe shaking of the guide element during movement due to a large assembly gap between the locking element and the guide element, thus reducing the assembly precision requirements between the locking element and the guide element. Furthermore, the improved fit between the locking element and the locking hole of the ribbon cartridge allows the locking element to be stably inserted into the locking hole even with a smaller hole, reducing the design requirements for the ribbon cartridge locking hole.
[0011] Secondly, the locking element and the guide element abut against each other in the second direction, generating damping friction. This damping friction provides resistance to the locking element. When the printer is subjected to external forces, the damping friction can hinder the switching of the locking element, preventing it from moving excessively under external interference and causing the ribbon cartridge to be accidentally unlocked. This reduces the risk of the locking element easily separating from the ribbon cartridge, improving the safety of the printer during handling and use. Furthermore, during the process of the elastic element driving the locking element, the damping friction can slow down the movement speed of the locking element, preventing it from impacting the ribbon cartridge due to excessive movement speed, thus improving the printer's operational stability and lifespan.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] This application provides a locking component 110; please refer to [link / reference]. Figure 1 This addresses the aforementioned issues. Applied to printer 1, it should be noted that printer 1 in this application can be a wire marking machine or a barcode printer 1, etc., and is not limited thereto. However, for ease of understanding, the following description uses a wire marking machine as an example.
[0026] Please see Figure 2 The locking assembly 110 may include a carrier 111, a locking member 112, and an elastic member 113. The carrier 111 and the locking member 112 are movably engaged, and the elastic member 113 is connected between the locking member 112 and the carrier 111.
[0027] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0028] Please see Figure 2 The carrier 111 has a guide 1111. The carrier 111 can be the housing or mounting plate of the printer 1, etc., and the guide 1111 can be a mounting post or fastener, etc., without limitation. For example, in one case, the carrier 111 can be a mounting plate, and the guide 1111 can be a mounting post, etc., provided on the carrier 111. In some cases, the carrier 111 can be a mounting plate, and the guide 1111 can be a mounting post, etc., provided on the carrier 111. In other cases, the carrier 111 can be a housing, and the housing has a threaded hole. The guide 1111 can be a stud, and the stud is installed in the threaded hole; these are not listed here.
[0029] Please continue reading. Figure 2 The locking member 112 and the guide member 1111 are movably engaged, and the guide member 1111 is used to guide the locking member 112 along a first direction (e.g., Figure 2The locking element 112 (as shown in L1) moves to switch between a locked position and an unlocked position. The locking element 112 can reciprocate or move unidirectionally along a first direction without limitation, and can be selected and designed according to specific needs. The locking element 112 can cooperate with the guide element 1111, which can guide the locking element 112 to switch between the locked and unlocked positions. The carrier element 111 can guide the locking element 112 along the first direction, thereby enabling the locking element 112 to switch between different states. This cooperation between the locking element 112 and the guide element 1111 improves the stability of the locking element 112's movement and prevents the locking element 112 from deviating from the preset trajectory and failing to lock the ribbon cartridge 2.
[0030] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or at least two. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0031] Please see Figure 3 One end of the elastic element 113 is connected to the locking element 112, and the other end of the elastic element 113 is connected to the carrier 111. The elastic element 113 can be a spring or a sheet, etc., and is not limited thereto. In other words, during the switching between the locked and unlocked positions, the carrier 111 drives the elastic element 113, and the elastic element 113 can drive the locking element 112 to switch from one of the locked or unlocked positions to the other. For example, please refer to... Figure 3 as well as Figure 4 The elastic element 113 can be a spring. The printer 1 has a cover 130 and a body 140, with the cover 130 rotatable relative to the body 140. When the user opens the cover 130, the cover 130 abuts against and drives the locking element 112 to the unlocked position, at which point the spring is driven and stretched. When the user closes the cover 130, the cover 130 releases its driving effect on the locking element 112. At this time, the spring can drive the locking element 112 to the locked position. The opening and closing range of the cover 130 is constant, and the locking element 112 causes the spring to deform, with the spring deformation being relatively stable. The spring force can be relatively constant, so even if the user closes the cover 130 too quickly, the spring will still drive the locking element 112 with a relatively stable force to ensure that the locking element 112 can stably lock the ribbon cartridge 2, avoiding situations where the locking element 112 moves too fast, resulting in poor locking effect or locking failure.
[0032] In related technologies, due to factors such as assembly clearance, even with a guiding structure, the stability of existing locking components still falls short of expectations. Please refer to the following: Figure 3 The extension direction of the elastic element 113 in this application and the first direction (e.g.) Figure 3 There is an angle between the extension direction of the elastic element 113 and the first direction (as shown in L1 in the diagram). In other words, the extension direction of the elastic element 113 intersects with the first direction, i.e., the angle is not 0° or 180°. Preferably, the angle can be greater than 0° and less than 90°, such as 5°, 45°, 60°, or 85°. The elastic element 113 can be in the second direction (e.g., Figure 3 A component force is generated on the locking member 112 (as shown in L2). The first direction and the second direction intersect. For example, the first direction can be the length direction of the locking member 112, and the second direction can be the width direction of the locking member 112, with the first and second directions intersecting. This allows the elastic member 113 to generate a component force in the second direction. The component force of the elastic member 113 in this application can drive the locking member 112 to move, causing the locking member 112 and the guide member 1111 to abut against each other in the second direction. The component force can reduce the amplitude of the left-right swaying of the locking member 112 during movement, resulting in better stability of the locking member 112. The locking member 112 can be inserted more precisely into the locking hole 210 of the ribbon cartridge 2, improving the installation stability of the ribbon cartridge 2.
[0033] Compared to related technologies, in this application, the cooperation between the elastic element 113 and the locking element 112 improves the movement stability of the locking element 112. This avoids severe shaking of the guide element 1111 during movement due to a large assembly gap between the locking element 112 and the guide element 1111, thus reducing the assembly precision requirements between the locking element 112 and the guide element 1111. Furthermore, the improved fit between the locking element 112 and the locking hole 210 of the ribbon cartridge 2 allows the locking element 112 to be stably inserted into the locking hole 210 even with a smaller locking hole, reducing the design requirements for the locking hole 210 of the ribbon cartridge 2.
[0034] In the event of a printer being bumped or knocked, the locking mechanism can easily detach from the ribbon cartridge, causing the ribbon cartridge to lose its securing function and consequently affecting the printer's printing accuracy. Please continue reading. Figure 3In this application, the locking member 112 and the guide member 1111 abut against each other in the second direction, generating damping friction. This damping friction provides resistance to the locking member 112. When the printer 1 is subjected to external force, the damping friction can hinder the switching of the locking member 112, preventing the locking member 112 from moving excessively under external interference, which could lead to the ribbon cartridge 2 being incorrectly unlocked. This reduces the risk of the locking member 112 easily separating from the ribbon cartridge 2, improving the safety of the printer 1 during handling and use. Furthermore, during the process of the elastic member 113 driving the locking member 112, the damping friction can slow down the movement speed of the locking member 112, preventing it from impacting the ribbon cartridge 2 due to excessive movement speed, thus improving the stability and service life of the printer 1.
[0035] Understandably, carrier 111 can be the housing of printer 1, and ribbon cartridge 2 can be mounted on carrier 111, with carrier 111 positioning ribbon cartridge 2. Please refer to [link / reference]. Figure 1 The locking member 112 has a locking part 1124, which may be hook-shaped and can be inserted into the locking hole 210. Based on the original locking hole 210 of the ribbon cartridge 2, the carrier 111 and the locking member 112 abut against each other in the second direction, so that the locking part 1124 of the locking member 112 is offset relative to the locking hole 210 of the ribbon cartridge 2. The locking part 1124 is located on one side of the central axis of the locking hole 210. This reduces the minimum gap between the locking part 1124 and the hole wall of the locking hole 210, and avoids the ribbon cartridge 2 from shaking significantly due to a large assembly gap between the locking member 112 and the ribbon cartridge 2. This reduces the shaking amplitude of the ribbon cartridge 2 relative to the carrier 111.
[0036] Please refer again to the embodiments in this application. Figure 2 The locking member 112 has a guide hole 1121, and the guide member 1111 is movably inserted into the guide hole 1121. For example, the guide hole 1121 can be a strip-shaped hole, and the guide member 1111 can be inserted into the guide hole 1121. During this period, the hole wall of the guide hole 1121 restricts the guide member 1111, so that the locking member 112 can move relative to the guide member 1121 along the extending direction of the guide hole 1121. The strip-shaped hole extends along a first direction. Through the cooperation of the guide member 1111 and the locking member 112, the locking member 112 is restricted to move along a preset trajectory, so that it can accurately switch between the unlocked position and the locked position, which ensures that the locking member 112 can work stably.
[0037] In a more specific implementation, please refer again. Figure 2The guide hole 1121 can be a closed opening structure. It should be noted that a closed opening refers to a hole structure whose circumferential boundary is completely surrounded by the hole wall. A closed opening can be a through hole or a blind hole, etc., and is not limited here. In other words, when the mounting component 111 passes through the guide hole 1121 and moves relative to the locking component 112, the guide hole 1121 has a continuous hole wall. The hole wall can constrain the guide component 1111 throughout its entire stroke, avoiding the risk of the guide component 1111 detaching from the guide hole 1121, and effectively resisting external lateral force interference through the complete limitation of the hole wall. This improves the stable operation of the guide component 1111 and the locking component 112, ensuring that the locking component 112 always moves accurately along the preset trajectory.
[0038] In another embodiment, the guide hole 1121 can be a strip-shaped hole, and the locking member 112 can have a notch communicating with the guide hole 1121. The notch is located on one side of the extension path of the guide hole 1121. It should be noted that the extension path of the guide hole 1121 refers to its trajectory along its own extension direction. For example, the extension path of the strip-shaped hole can be the path along which the guide member 1111 moves. Exemplarily, the notch can penetrate one side of the guide hole 1121, connecting the guide hole 1121 to the outside. During use, the guide member 1111 can abut against the side of the guide hole 1121 away from the notch. This also serves to limit and guide the guide member 1111, ensuring that the locking member 112 always moves accurately along a preset trajectory. The notch can allow at least a partial opening of the guide hole 1121. During the installation or removal of the locking member 112, even if other components are installed on the guide member 1111, the user can still directly separate the guide member 1111 and the locking member 112 through the notch, simplifying the disassembly and assembly steps of the printer 1.
[0039] In another embodiment, a guide groove is formed on the surface of the guide 1111, the guide 1111 extends into the guide groove, and moves along the guide groove. For example, the guide groove can extend in a first direction, and the end of the guide 1111 can extend into the guide groove and slide in cooperation with the guide groove, so that the guide 1111 can move along the extension direction of the guide groove, which will not be described in detail here.
[0040] Please refer again to the embodiments in this application. Figure 2 The locking member 112 is movably mounted on the carrier 111. For example, the carrier 111 is a mounting plate, the locking member 112 is mounted on the carrier 111, and the locking member 112 is movably positioned relative to the carrier 111. The carrier 111 is provided with a limiting portion 1112, which limits the locking member 112 and the carrier 111 in the height direction (e.g., ...). Figure 2As shown in L3 in the diagram, the locking member 1112 abuts against the guide member 1111. For example, the limiting part 1112 can be provided on the guide member 1111, which extends vertically. The extension direction of the guide member 1111 can be the height direction, intersecting with both the first and second directions. The limiting part 1112 can be a protrusion or a fastener, etc. The fastener is detachably mounted on the guide member 1111, abutting against the surface of the locking member 112, causing the locking member 112 and the carrier member 111 to abut against each other. The wall of the guide hole 1121 can abut against the guide member 1111 in the second direction, thus limiting the locking part 1112 and the carrier member 111. This allows the locking member 112 to move only in the first direction, reducing the amplitude of wobbling in other directions during its movement. It also prevents the locking member 112 from causing the elastic member 113 to tilt in other directions, improving the installation accuracy of the ribbon cartridge 2, which in turn improves the printing accuracy of the printer 1.
[0041] In one implementation, please refer to Figure 5 The locking member 112 has a protruding abutment portion 1123 near the surface of the carrier 111, which abuts against the surface of the carrier 111. For example, the abutment portion 1123 can be integrally stamped from the carrier 111, and the abutment portion 1123 can protrude relative to the surface of the carrier 111. The abutment portion 1123 allows a partial area of the locking member 112 to abut against the surface of the carrier 111, creating a gap between other areas of the locking member 112 and the carrier 111, thereby reducing the contact area between them. This partial protruding contact significantly reduces the frictional resistance between them, thus reducing friction and improving the smoothness of the locking member 112's movement. Furthermore, simply smoothing the surface of the abutment portion 1123 further reduces the friction between the locking member 112 and the carrier 111, lowering the manufacturing difficulty of the locking member 112.
[0042] In this application, please refer to Figure 5 In the case where the damping shaft 121 can be mounted on the second guide 1114, the spring is located vertically between the first functional component 120 and the locking member 112. For example, the second guide 1114 can be used for a transmission gear, and in the case where the transmission gear can be mounted on the second guide 1114, the spring is located between the transmission gear and the locking member 112. This structural layout eliminates the need for the spring to occupy separate mounting space. Instead, it utilizes the existing clearance between the first functional component 120 and the locking member 112, effectively reducing the space occupied by the locking structure. This avoids wasting internal space of the printer 1 by setting up a separate mounting area for the spring, further refining the internal structural layout of the printer 1.
[0043] In the embodiments of this application, please refer to Figure 6The number of guide members 1111 is at least two, such as two, three, or more, without limitation. At least two guide members 1111 are movablely engaged with the locking member 112, and at least two guide members 1111 form limiting engagements with multiple locations on the locking member 112. For example, the locking member 112 has at least two guide holes 1121, and each guide member 1111 can be installed in one guide hole 1121, with each guide member 1111 engaging with the wall of the corresponding guide hole 1121. Of course, in other cases, at least two guide holes 1121 can simultaneously extend into a single guide hole 1121, and at least two guide holes 1121 can engage with the wall of the same guide hole 1121, but these are not listed here. During this period, this application uses different guides 1111 to constrain the locking member 112 at multiple points, ensuring that the locking member 112 moves in the first direction, reducing its swaying amplitude during movement, and making the movement path of the locking member 112 more precise and stable. This avoids deviations in the path of the locking member 112 due to only a single point of constraint between the guides 1111 and the locking member 112. At the same time, under the elastic force of the elastic member 113, the guides 1111 and the locking member 112 abut against each other and generate abutting force. At least two mounting members 111 bear the abutting force simultaneously, which avoids structural damage caused by the concentration of internal force on a single mounting member 111.
[0044] Please see Figure 6 The guide 1111 includes at least a first guide 1113 and a second guide 1114. The first guide 1113 is connected to the elastic member 113. Specifically, the locking member 112 may have a connecting portion 1122 on its surface, which may be a stamped protrusion. One end of the elastic member 113 is connected to the connecting portion 1122, and the other end is connected to the first guide 1113. The first guide 1113 has a threaded hole, which locks the end of the elastic member 113 onto the mounting carrier 111, further improving the installation stability of the elastic member 113 and preventing it from detaching from the first guide 1113, thus ensuring that the elastic member 113 can be stably installed on the first guide 1113.
[0045] Please see Figure 7 The second guide 1114 is adapted to mount the first functional component 120. The first functional component 120 can be a transmission component 122, a damping shaft 121, etc., and is not limited thereto. The damping shaft 121 can connect to the ribbon cartridge 2 to drive the ribbon movement within the cartridge 2, allowing a new ribbon to be placed corresponding to the consumable. The consumable can be a sleeve, sticker, etc., and is not limited thereto. The transmission component 122 can be a transmission gear, which can be connected to the damping shaft 121 and to a drive motor to drive the damping shaft 121 to rotate. For example, please refer to [reference needed]. Figure 8The first functional component 120 can be a damping shaft 121 and a transmission component 122. The first guide 1113 is provided with a stepped portion 1115, which is suitable for mounting the damping shaft 121 and the transmission component 122. Further, the stepped portion 1115 has a stepped surface, which is used for limiting the engagement with the transmission component 122. The damping shaft 121 and the transmission component 122 abut against each other and are connected by transmission. In this application, the stepped surface can prevent the first functional component 120 from displacing towards the locking member 112. This makes the locking member 112 and the first functional component 120 stably distributed in the extension direction of the carrier 111, avoiding positional interference between the two due to relative movement. At the same time, relying on the supporting effect of the stepped surface, the first functional component 120 always maintains a preset position in the vertical direction and will not be vertically offset due to external forces or vibrations, thereby ensuring the stability and reliability of the overall structure during operation and reducing the risk of printer 1 malfunction.
[0046] In some other cases, in addition to the first functional component 120, the printer 1 may also include a second functional component, which may be a drive motor, controller, etc. The second functional component can be connected to the first functional component 120 by transmission or electricity to complete more complex work tasks.
[0047] This application also provides a movement 100, please refer to... Figure 9 The movement 100 includes the aforementioned locking component 110.
[0048] This application also provides a printer 1, please refer to... Figure 10 Printer 1 includes the mechanism 100 as described above.
[0049] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.
[0050] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
Claims
1. A locking component for use in a printer, characterized in that, The locking assembly includes a carrier, a locking element, and an elastic element, wherein: The carrier has a guide, and the locking member is movably engaged with the guide.
