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, the ribbon cartridge needs to be locked by a locking mechanism to ensure reliable installation. This locking mechanism is driven and can switch between a locked and a released state. To ensure that the locking mechanism can switch states along a preset trajectory, a guiding structure needs to be arranged in the printer, which leads to limited installation space inside the printer. 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 component for use in a printer. A mounting carrier is used to mount a first functional component of the printer. The locking component is movably coupled with the mounting carrier to guide the locking component to switch between a locked position and an unlocked position. When the locking component is in the locked position, it limits and locks the ribbon cartridge. When the locking component is in the unlocked position, it releases the locking of the ribbon cartridge.
[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] The mounting carrier can install the first functional component, which includes, but is not limited to, damping shafts, springs, and transmission components. The mounting carrier provides load-bearing support for the first functional component to ensure its stable operation. The mounting carrier cooperates with the locking component to guide the locking component between the locked and unlocked positions. The mounting carrier ensures that the locking component can switch states along a preset trajectory to meet the requirement of limiting the locking of the ribbon cartridge and preventing the locking component from deviating from the preset trajectory and failing to lock the ribbon cartridge.
[0010] Compared to related technologies, this application, based on the mounting carrier carrying the first functional component, can use the mounting carrier to guide the locking component. This allows the mounting carrier to simultaneously carry the first functional component and guide the locking component, eliminating the need for a separate component inside the printer to guide the locking component. This reduces the printer's internal space occupancy, avoids internal space constraints, and facilitates the installation of internal components. Attached Figure Description

[0025] 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.
[0026] In existing technology, a guiding structure is required in the printer to ensure that the locking element can switch states along a preset trajectory. For example, the guiding structure is a guide block set in the casing, which cooperates with the locking element to guide the locking element to move along the preset trajectory. However, the guide block occupies a large amount of internal space in the printer, which leads to a shortage of installation space inside the printer.
[0027] This application provides a locking component 110 to solve the above-mentioned problems. Please refer to... Figure 1 The locking component 110 is applied to the printer 1. It should be noted that the 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.
[0028] Please see Figure 2 The locking assembly 110 may include a mounting carrier 111 and a locking element 112, the locking element 112 being movably configured relative to the mounting carrier 111.
[0029] 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.
[0030] Please see Figure 2 as well as Figure 3 The mounting carrier 111 is used to mount the first functional component 120 of the printer 1. The mounting carrier 111 can be a columnar structure, and the first functional component 120 includes, but is not limited to, a damping shaft 121, a spring 122, and a transmission component 123. For example, the damping shaft 121 can be mounted on the mounting carrier 111 and rotatably positioned around it. In this case, the transmission component 123 can be connected to the damping shaft 121 to drive the ribbon in the ribbon cartridge 2, so that the new ribbon cartridge 2 is aligned with the consumable. The mounting carrier 111 provides load-bearing support for the first functional component 120 to ensure stable operation. Of course, in some cases, the transmission component 123 can be mounted on the mounting carrier 111 simultaneously with the damping shaft 121. The consumables include, but are not limited to, sleeves and stickers.
[0031] Understandably, in some other cases, in addition to the first functional component 120, the printer 1 may also include a second functional component, such as a drive motor or a controller, which can be connected to the first functional component 120 by means of transmission or electricity to complete more complex tasks.
[0032] 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, a first object can be one or more. 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.
[0033] In this application, please refer to Figure 4The locking member 112 engages with the mounting carrier 111 to guide the locking member 112 between a locked position and an unlocked position. Furthermore, when the locking member 112 is in the locked position, it limits and locks the ribbon cartridge 2. When the locking member 112 is in the unlocked position, it releases the lock on the ribbon cartridge 2. Both the locked and unlocked positions can be a specific location or a segment of the moving path of the locking member 112. For example, the locked position can be a region of the moving path of the locking member 112; that is, the locking member 112 can limit and lock the ribbon cartridge 2 by moving to any position within that region. For example, the locking member 112 has a limiting hook 1125, which is movably set relative to the ribbon cartridge 2. The ribbon cartridge 2 has a locking hole 210 located on the moving path of the limiting hook 1125. When the locking member 112 is driven to the locked position, the limiting hook 1125 can extend into the locking hole 210 and hook onto the wall of the locking hole 210 to restrict the movement of the ribbon cartridge 2, so that the ribbon cartridge 2 can be locked onto the printer 1. When the locking member 112 is driven to the unlocked position, the limiting hook 1125 of the locking member 112 and the ribbon cartridge 2 separate, at which point the user can replace the ribbon cartridge 2. It is understood that the mounting carrier 111 guides the locking member 112 so that the locking member 112 can stably switch between the locked and unlocked positions. The mounting carrier 111 ensures that the locking member 112 can switch states along a preset trajectory to meet the requirement of the locking member 112 limiting and locking the ribbon cartridge 2, and to prevent the locking member 112 from leaving the preset trajectory and failing to lock the ribbon cartridge 2. This prevents the locking element 112 from tilting or shifting during the switching process, ensuring that the limit hook 1125 can accurately move into the locking hole 210, and avoiding situations such as poor locking effect or locking failure due to the uncertain movement path of the limit hook 1125.
[0034] It should be noted that this application does not limit the way the driving locking member 112 switches between the locked and unlocked positions. For an example, please refer to... Figure 5 The printer 1 has a cover 130 and a body 140, with the cover 130 rotatably positioned relative to the body 140. The cover 130 can be fastened to the surface of the body 140 to close the mounting space on the surface of the body 140. This mounting space is suitable for installing the ribbon cartridge 2. Simultaneously, the locking element 112 is linked to the cover 130. When the user closes the cover 130 to close the mounting space, the cover 130 moves the locking element 112 to the locked position. When the user opens the cover 130 to open the mounting space, the cover 130 moves the locking element 112 to the unlocked position. Of course, in other cases, the printer 1 may also be equipped with a control motor that can drive the locking element 112 to switch between the locked and unlocked positions; details will not be elaborated here.
[0035] Compared to related technologies, this application, based on the mounting carrier 111 carrying the first functional component 120, can utilize the mounting carrier 111 to guide the locking component 112. This allows the mounting carrier 111 to simultaneously carry the first functional component 120 and guide the locking component 112, eliminating the need for additional components inside the printer 1 to guide the locking component 112. This reduces the internal space occupancy of the printer 1, avoids internal space constraints, and facilitates the installation of internal components of the printer 1.
[0036] In the embodiments of this application, please refer to Figure 4 The locking member 112 has a guide hole 1121, and the mounting member 111 is movably inserted into the guide hole 1121. For example, the guide hole 1121 can be a strip-shaped hole, and the mounting member 111 can be inserted into the guide hole 1121. During this time, the hole wall of the guide hole 1121 restricts the mounting member 111, allowing the mounting member 111 to move along the extension direction of the guide hole 1121. The extension direction of the strip-shaped hole is the preset direction of movement of the locking member 112. This setting, through the cooperation of the mounting member 111 and the locking member 112, restricts the locking member 112 to move along a preset trajectory, enabling it to accurately switch between the unlocked and locked positions, thus ensuring the stable operation of the locking member 112.
[0037] In a more specific implementation, please refer to [link / reference needed]. Figure 4 The 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 mounting component 111 throughout its entire stroke, avoiding the risk of the mounting component 111 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 mounting component 111 and the locking component 112, ensuring that the locking component 112 always moves accurately along the preset trajectory.
[0038] In another embodiment, the locking member 112 may have a notch communicating with the guide hole 1121, located on one side of the extension path of the guide hole 1121. The extension path of the guide hole 1121 refers to its trajectory along its own extension direction. For example, the guide hole 1121 may be a strip-shaped hole, and the extension path of the strip-shaped hole may be the path along which the guide member 1121 moves. Exemplarily, during use, the mounting member 111 may abut against the hole wall of the guide hole 1121 on the side away from the notch. This also serves to limit and guide the mounting member 111, ensuring that the locking member 112 always moves accurately along a preset trajectory. The notch allows at least a partial opening of the guide hole 1121. During the installation or removal of the locking member 112, the first functional component 120 does not need to be removed from the mounting member 111; the mounting member 111 and the locking member 112 can be directly separated through the notch, simplifying the installation and removal steps of the printer 1.
[0039] In another embodiment, the surface of the locking member 112 is provided with a guide groove, and the mounting member 111 extends into the guide groove and moves along the guide groove. For example, the end of the mounting member 111 can extend into the guide groove and slide in engagement with it. This allows the locking member 112 to move along the extension direction of the guide groove, ensuring that the locking member 112 always moves precisely along a preset trajectory; further details are omitted here.
[0040] In the embodiments of this application, please refer to Figure 6 as well as Figure 7 The mounting carrier 111 may include a first segment 1111 and a second segment 1112 connected together. The mounting carrier 111 is guided and engaged with a guide hole 1121 via the first segment 1111, and the second segment 1112 is used to mount the first functional component 120. For example, the first segment 1111 and the second segment 1112 can be distributed vertically. The first segment 1111 is slidably engaged with the locking member 112 to constrain the locking member 112 to move along a preset path. The second segment 1112 can mount the damping shaft 121. The diameter of the first segment 1111 is larger than the diameter of the second segment 1112, forming a step portion 1113 at the connection between the first segment 1111 and the second segment 1112. The stepped surface of the step portion 1113 is used to limit the engagement with the first functional component 120. The stepped surface can prevent the first functional component 120 from displacing towards the locking member 112. This ensures that the locking member 112 and the first functional component 120 are stably distributed in the extension direction of the mounting carrier 111, avoiding positional interference due to relative movement. At the same time, relying on the load-bearing capacity of the stepped surface, the first functional component 120 always maintains its preset position during operation, and will not tilt or shift due to external forces or vibrations. This ensures the stability and reliability of the overall structure during operation and reduces the risk of printer 1 malfunction.
[0041] In one implementation, please refer to [link / reference needed]. Figure 6 as well as Figure 7 The number of mounting carriers 111 is at least two, such as two, three, or more, without limitation. At least two mounting carriers 111 can mount a greater number of first functional components 120. Simultaneously, at least two mounting carriers 111 form limiting engagements with multiple locations of the locking member 112. For example, the locking member 112 has at least two guide holes 1121, and each mounting carrier 111 can be installed in one guide hole 1121, with each mounting carrier 111 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 multiple constraints on the locking member 112 through different carriers to ensure that the locking member 112 moves along a preset trajectory, reducing radial swaying or offset 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 mounting carrier 111 and the locking member 112. At the same time, under the action of external force, the mounting carrier 111 and the locking member 112 abut against each other and generate abutting force. At least two mounting carriers 111 bear the abutting force simultaneously, which avoids structural damage caused by the concentration of internal force on a single mounting carrier 111.
[0042] In another case, at least two mounting components 111 jointly support the same first functional component 120 to avoid structural deformation or installation offset caused by excessive load on a single mounting component 111. At least two mounting components 111 can install and stably support more components at the same time, which will not be elaborated here.
[0043] In this embodiment, the mounting carrier 111 is used to mount the damping shaft 121 and / or the spring 122. In one embodiment, please refer again to... Figure 4The damping shaft 121 is connected to the ribbon cartridge 2. Driven by the transmission component 123 or the drive motor, the damping shaft 121 drives the ribbon in the ribbon cartridge 2. The mounting carrier 111 is used to mount the damping shaft 121, which drives the ribbon in the ribbon cartridge 2 so that the new ribbon cartridge 2 is aligned with the consumable. For example, the damping shaft 121 has a torsion spring and a damping block. The torsion spring receives the driving action of the transmission component 123 and drives the damping block through damping friction. The damping block is driven and continuously winds the ribbon. As the weight of the ribbon on the damping block increases, the load on the damping block increases, and the damping friction is insufficient to maintain the damping block rotating at a constant speed. The more ribbon wound on the damping block, the lower its angular velocity. By reducing the angular velocity, the linear velocity of the ribbon wound on the damping block tends to be constant, avoiding excessive linear velocity of the ribbon wound on the damping block, which would affect printing accuracy. Mounting carrier 111 serves both to support the damping shaft 121 suitable for driving the ribbon cartridge 2 and to guide the locking member 112 that locks the ribbon. This single mounting carrier 111 performs two different functions, avoiding excessive spacing between the damping shaft 121 and the locking member 112, which would otherwise require different mating parts or guides, thus optimizing the internal space layout. This allows the two components related to the ribbon cartridge 2 to be positioned closer together, enabling both the damping shaft 121 and the locking member 112 to accommodate smaller ribbon cartridges 2 and reducing the space occupied within the printer 1.
[0044] In another implementation, please refer to [the original text]. Figure 8The mounting carrier 111 is used to mount the spring 122, which is connected between the mounting carrier 111 and the locking member 112. For example, the locking assembly 110 also includes the spring 122. The surface of the locking member 112 is provided with a connecting portion 1126, which may be a stamped protrusion. One end of the spring 122 is connected to the connecting portion 1126, and the other end is connected to the mounting carrier 111. The mounting carrier 111 has a threaded hole, which locks the end of the spring 122 onto the mounting carrier 111, further improving the installation stability of the spring 122 and preventing it from detaching from the mounting carrier 111. In actual use, 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 member 112 to the unlocked position, at which point the spring 122 is driven and stretched. When the user closes the cover 130, the cover 130 releases the driving effect on the locking member 112. At this time, the spring 122 can drive the locking member 112 to move to the locked position. The opening and closing range of the cover 130 is constant, and the locking member 112 causes the spring 122 to deform, and the deformation of the spring 122 is relatively stable. The elastic force of the spring 122 can be relatively constant. Even if the user closes the cover 130 too quickly, the spring 122 will still drive the locking member 112 with a relatively stable force to ensure that the locking member 112 can stably lock the ribbon box 2, avoiding situations where the locking member 112 moves too fast, resulting in poor locking effect or locking failure.
[0045] In yet another embodiment, further please refer to Figure 9 The mounting carrier 111 includes at least a first mounting carrier 1114 and a second mounting carrier 1115. The first mounting carrier 1114 is used to mount the damping shaft 121, and the second mounting carrier 1115 is used to mount the spring 122. The first mounting carrier 1114 and the second mounting carrier 1115 respectively support the damping shaft 121 and the spring 122. This, by having mounting carriers 111 with different functions simultaneously forming multiple constraints on the locking member 112, ensures that the locking member 112 moves along a preset trajectory, reducing its radial sway or offset during movement, making the movement path of the locking member 112 more precise and stable, and further realizing that the mounting carrier 111 reduces the internal space occupancy of the printer 1.
[0046] Of course, in some other cases, at least two mounting components 111 may also include a third mounting component, a fourth mounting component, etc. The third mounting component may be used to mount the pressure roller, the fourth mounting component may be used to mount the drive motor, etc., which are not listed here.
[0047] Please refer again to the embodiments in this application. Figure 9With the damping shaft 121 mounted on the first mounting carrier 1114, the spring 122 is located between the damping shaft 121 and the locking member 112. For example, the damping shaft 121 is mounted on the first mounting carrier 1114. In the horizontal direction (e.g.) Figure 9 In the direction shown in L2), the first mounting carrier 1114 corresponds to the spring 122. In the height direction (as shown in L2), the first mounting carrier 1114 corresponds to the spring 122. Figure 9 As shown in L1, the spring 122 is located in the space between the damping shaft 121 and the locking member 112. This structural layout eliminates the need for the spring 122 to occupy additional independent installation 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 assembly 110. This avoids wasting internal space of the printer 1 by setting up a separate installation area for the spring 122, and further compresses the internal structural layout of the printer 1.
[0048] In the embodiments of this application, please refer to Figure 10 The locking member 112 may include a first arm 1122, a second arm 1123, and a third arm 1124, with the second arm 1123 connected between the first arm 1122 and the third arm 1124. The locking assembly 110 is formed in the first arm 1122, and the second arm 1123 extends along the height direction (e.g., ...). Figure 10 As shown in L1, the first arm 1122 and the third arm 1124 are spaced apart in the height direction, with the third arm 1124 adapted to limit the ribbon cartridge 2. By providing a second arm 1123 between the first arm 1122 and the third arm 1124, the first arm 1122 and the third arm 1124 are spaced apart in the height direction. This allows the third arm 1124 to extend outside the casing of the printer 1 and connect with the ribbon cartridge 2, which reduces the space occupied in the horizontal direction and optimizes the space allocation efficiency inside the device.
[0049] In the embodiments of this application, please refer to Figure 1 The locking assembly 110 may also include a mounting plate 113, which can be a metal plate or similar material, and is not limited thereto. The mounting carrier 111 is mounted on the mounting plate 113, and the locking member 112 is slidably mounted on the mounting plate 113. The mounting plate 113 provides support for the mounting carrier 111 and the locking member 112, ensuring that they can move relative to each other. This effectively reduces the shaking of the mounting carrier 111 under load and the offset of the locking member 112 during sliding, ensuring the stability of both components in their working state. Furthermore, this allows the mounting carrier 111 and the locking member 112 to be integrated onto the mounting plate 113, thus forming a mounting module. The installation, removal, and maintenance of the mounting carrier 111 and the locking member 112 can be performed around the mounting unit, simplifying the installation process.
[0050] In some other cases, the mounting carrier 111 can be located on the casing of the printer 1. The mounting carrier 111 can still be used to install the first functional component, which will not be described in detail here.
[0051] This application also provides a movement 100; please refer to the previous section. Figure 11 The movement 100 may include the locking assembly 110 as described above.
[0052] This application also provides a printer 1, please refer to... Figure 12 The printer 1 may include the mechanism 100 as described above. The printer 1 in this application may be a wire marking machine or a barcode printer 1, etc., and is not limited thereto.
[0053] 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.
[0054] 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.
