Abstract
Description
Technical Field
[0001] This utility model belongs to the field of printer technology, specifically relating to a limiting component, a tube clamp, a housing assembly, and a printer. Background Technology
[0002] A printer is a computer peripheral device that outputs electronic documents or images to paper or other media. It receives digital signals from a computer, mobile phone, or other device and uses printing technology to "print" physical copies of text, graphics, or photographs. There are various types of printers, such as line marker printers, label printers, and invoice printers.
[0003] In printing technologies such as wire marking machines, a tube clamp is usually installed on the top cover to limit the movement of the sleeve to be printed, ensuring that the sleeve moves along a preset transport path and preventing it from deviating from the path. However, in some printer products, the tube clamp is not very effective at limiting the movement of the sleeve. Utility Model Content
[0004] The purpose of this application is to provide a limiting component, a crimping device, a housing assembly, and a printer to solve the technical problem that existing crimping devices do not have a good limiting effect on printing media.
[0005] This application is achieved through the following means: In a first aspect, embodiments of this application provide a limiting member applied to a printer's tube clamp. The limiting member is mounted on the printer's top cover via an attachment. The limiting member is located on the side of the attachment away from the top cover. The limiting member is used to limit and cooperate with the sleeve to be printed on the printer body. The end of the limiting member away from the top cover is provided with a recessed structure to form a limiting space for constraining the sleeve to be printed. The limiting member has a slot inside.
[0006] Secondly, the present application provides a pipe crimping device, including the limiting member provided in the first aspect embodiment. The pipe crimping device also includes an attachment and a mounting post. The limiting member is fixed to the attachment, the mounting post is used to install to the upper cover, the attachment is movably sleeved outside the mounting post, and the limiting member is movably engaged with the mounting post along the axial direction of the mounting post.
[0007] Thirdly, embodiments of this application provide a housing assembly, including a top cover and a crimper provided in the second aspect embodiment, wherein the crimper is mounted on the top cover.
[0008] Fourthly, embodiments of this application provide a printer, including the housing assembly provided in the third aspect embodiment.
[0009] The technical solution provided in this application can achieve the following beneficial effects: In this application, by setting a groove inside the limiting component, the thickness of the limiting component can be effectively reduced. During the injection molding process of the limiting component, the reduced thickness of the limiting component can effectively reduce the probability of shrinkage, thereby improving the dimensional accuracy of the limiting component and reducing the probability of uneven structures such as concavity and convexity on the surface of the limiting component outside the preset shape. This allows the surface of the limiting component to maintain the preset shape as much as possible, ensuring a stable fit between the limiting component and the sleeve to be printed. At the same time, the surface of the limiting component can be kept as smooth as possible, reducing friction between it and the sleeve to be printed, and reducing structural damage to the surface of the sleeve caused by friction.

Detailed Implementation
[0013] The following description provides many different embodiments or examples for implementing various features of the present invention. The elements and arrangements described in the specific examples below are only for concise expression of the present invention and are merely examples, not intended to limit the present invention.
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. 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.
[0015] This application provides a limiting member 100, which can be referenced. Figures 1 to 3 As shown, the limiting member 100 is applied to the printer's tube clamp 10. The limiting member 100 is installed on the printer's top cover 20 via the attachment 200. The limiting member 100 is located on the side of the attachment 200 away from the top cover 20. The limiting member 100 is used to limit and cooperate with the sleeve to be printed at the printer body 30. The end of the limiting member 100 away from the top cover 20 is provided with a recessed structure 110 to form a limiting space for constraining the sleeve to be printed.
[0016] The recessed structure 110 on the surface of the limiting member 100 can form a limiting space, constraining the sleeve within the limiting space to prevent the sleeve from moving, thereby ensuring that the sleeve to be printed can be transported along the preset path.
[0017] In the embodiment provided, the limiting member 100 has a slot 120 inside, which can be referred to. Figure 2 and Figure 3As shown, the slot 120 is located inside the limiting member 100, which can effectively reduce the thickness of the limiting member 100. During the injection molding process of the limiting member 100, due to its reduced thickness, the corresponding amount of glue injected is also reduced, which can effectively reduce the probability of shrinkage of the limiting member 100 during the molding process, thereby improving the dimensional accuracy of the limiting member 100. To a certain extent, it can also reduce the probability of unevenness and irregularities on the surface of the limiting member 100 caused by shrinkage, and the surface of the limiting member 100 can maintain the preset shape as much as possible. When the limiting member 100 is in contact with the sleeve to be printed, the two can fit stably, improving the limiting effect on the sleeve.
[0018] In addition, since the risk of shrinkage is relatively small, the surface of the limiting member 100 can be kept as smooth as possible after the limiting member 100 is formed. When the limiting member 100 is in a limiting fit with the sleeve, the friction between the limiting member 100 and the sleeve is reduced, thus avoiding structural damage to the surface of the sleeve caused by the unevenness of the surface of the limiting member 100.
[0019] In practical use, the limiting member 100 rotates with the upper cover 20 to the surface of the machine body 30, and the sleeve is located between the limiting member 100 and the machine body 30. The recessed structure 110 of the limiting member 100 limits both sides of the sleeve to restrict the sleeve in a suitable position, so that the sleeve can maintain the preset conveying path. In some embodiments, the limiting member 100 can abut against the surface of the machine body 30; in other embodiments, the limiting member 100 may not be in direct contact with the machine body 30.
[0020] When the limiting member 100 and the sleeve are in a limiting engagement, the sleeve is located at the recessed structure 110 of the limiting member 100, and the sleeve and the surface of the limiting member 100 are in contact engagement, thereby achieving the limiting effect between them. In some embodiments of this application, the slot 120 is provided on the peripheral sidewall of the limiting member 100, and / or, the slot 120 is provided on the side of the limiting member 100 near the upper cover 20. The location of the slot 120 avoids the location of the recessed structure 110, which can effectively maintain the integrity of the surface of the recessed structure 110 and prevent the surface of the recessed structure 110 from having an opening that would affect the limiting effect with the sleeve.
[0021] In some embodiments of this application, the slot 120 is provided on the side of the limiting member 100 near the upper cover 20, as shown in the reference. Figure 2 and Figure 3 As shown, in the width direction of the limiting member 100, the depth of the two sides of the slot 120 is greater than the depth of the middle part, so as to adapt to the recessed structure 110 of the limiting member 100, so that the thickness of the limiting member 100 corresponding to the bottom of the slot 120 remains consistent.
[0022] The recessed structure 110 has a deep central recess and a shallower recess on both sides. The structure of the slot 120 is similar to that of the recessed structure 110, thereby maintaining a consistent thickness of the limiting member 100 between the bottom of the recessed structure 110 and the slot 120. That is, the thickness of the limiting member 100 corresponding to the bottom of the slot 120 can be kept consistent, further preventing the limiting member 100 from taking on a shape other than the preset shape due to uneven thickness during the injection molding process.
[0023] In some preferred embodiments of this application, the groove 120 is tapered from the opening to the bottom. Tapered 120 means that the cross-sectional size of the groove 120 gradually decreases, becoming smaller closer to the bottom. During the injection molding process of the limiting member 100, the mold corresponding to the groove 120 is easier to remove, facilitating demolding. Correspondingly, the sidewall of the limiting member 100 and the inner wall of the groove 120 are parallel in the width direction. Parallelism helps maintain a consistent thickness of the portion of the limiting member 100 between the two walls, further reducing the probability of unevenness during injection molding and ensuring the molded shape of the limiting member 100 closely matches the preset shape, thus improving the manufacturing precision of the limiting member 100.
[0024] This application also provides a hose clamp 10, which can be referred to. Figures 4 to 6 As shown, the crimping device 10 includes the limiting member 100 provided in any of the above embodiments, as well as an attachment member 200 and a mounting post 300. The limiting member 100 is fixed to the attachment member 200, the mounting post 300 is used to install to the upper cover 20, the attachment member 200 is movably sleeved outside the mounting post 300, and the limiting member 100 is movably engaged with the mounting post 300 along the axial direction of the mounting post 300.
[0025] The limiting member 100 is fixed to the attachment 200. The limiting member 100 achieves its movable engagement with the upper cover 20 through the movable engagement between the attachment 200 and the mounting post 300. The limiting member 100 can adjust the distance between itself and the upper cover 20 in the axial direction of the mounting post 300. During the process of limiting the sleeve, the limiting member 100 can adjust its relative position with the upper cover 20 according to the diameter of the sleeve it contacts. Sufficient space is reserved between the limiting member 100 and the machine body 30 for the sleeve to pass through, avoiding the situation where the space between the limiting member 100 and the machine body 30 is too small, causing the sleeve to be squeezed, resulting in changes in the shape of the sleeve and affecting the printing effect.
[0026] In some specific embodiments of this application, the mounting post 300 can be integrally injection molded with the top cover 20. When assembling the crimping device 10, connecting the attachment 200 to the mounting post 300 completes the assembly. Furthermore, the attachment 200 is provided in this embodiment primarily to avoid the mounting post 300 being directly connected to the limiting member 100, and to prevent the limiting member 100 from having an overly complex overall structure due to the corresponding connection structure, which could affect the limiting effect between the limiting member 100 and the sleeve.
[0027] The limiting member 100 is fixed to the attachment member 200, forming an integral structure with the attachment member 200, as can be seen from [reference]. Figures 1 to 5 As shown, the structure can move synchronously relative to the mounting post 300. In some preferred embodiments of this application, the limiting member 100 has a margin of movement relative to the mounting post 300 in its width direction to ensure that when the limiting member 100 is engaged with the sleeve to be printed, the limiting member 100 can move relative to the sleeve to be printed in its width direction, thereby enabling the recessed structure 110 of the limiting member 100 to adaptively align with the sleeve to be printed.
[0028] The limiting member 100 can not only move and cooperate with the mounting post 300 along the axial direction of the mounting post 300, but also move and cooperate with the mounting post 300 along its width direction. This is mainly so that when the limiting member 100 is in a limiting cooperation with the sleeve, the limiting member 100 can adjust its position along its width direction so that the limiting member 100 can be aligned with the sleeve.
[0029] It is understandable that when the limiting component 100 and the sleeve are in a limiting fit, both sides of the sleeve are subjected to limiting forces. Given that the limiting effect on both sides of the sleeve is the same, it can be assumed that the limiting component 100 and the sleeve are aligned.
[0030] If the sleeve deviates from its preset moving path, the limiting member 100 corresponding to the sleeve can move along its width direction and readjust its position so that the limiting member 100 can move in the direction of aligning with the sleeve, and finally achieve alignment between the limiting member 100 and the sleeve, so that the limiting effect between the limiting member 100 and the sleeve remains stable.
[0031] In some specific embodiments, a through hole may be provided on the attachment 200 for the mounting post 300 to pass through. The radial dimension of the through hole is larger than the radial dimension of the mounting post 300, and a movable gap is formed between the inner wall of the through hole and the outer peripheral wall of the mounting post 300, providing a margin of movement for the attachment 200 to move along its width direction.
[0032] In some other preferred embodiments, the surface of the attachment 200 away from the limiting member 100 is provided with a mounting groove 210, as can be seen from [reference]. Figure 2 and Figure 3As shown, the mounting groove 210 communicates with the slot 120 to facilitate injection molding. The mounting post 300 includes at least one first post 310, which can be referred to... Figure 6 As shown, the end of the first column 310 away from the upper cover 20 is located in the mounting groove 210, and the first column 310 is covered with an elastic member 400, which presses against the bottom of the mounting groove 210 and the upper cover 20.
[0033] The first post 310 is located within the mounting groove 210, using the space inside the mounting groove 210 as the movable space for the attachment 200 relative to the first post 310. Meanwhile, only a portion of the elastic member 400 is fitted over the first post 310, with the remainder located on the inner wall of the mounting groove 210. The expanded internal space of the mounting groove 210 increases the installation space for the elastic member 400, allowing it to be longer and providing more elastic force. Simultaneously, the restriction on the compression direction of the elastic member 400 is less, enabling it to adapt and deform even if the attachment 200 moves a certain distance along its width, thus improving the usability of the crimper 10.
[0034] In some preferred embodiments, the mounting post 300 includes at least one second post 320, which penetrates the attachment 200. A reinforcing rib 500 connects the second post 320 to the upper cover 20. The second post 320 guides the attachment 200. The reinforcing rib 500 between the second post 320 and the upper cover 20 improves the connection stability between them. Simultaneously, the reinforcing rib 500 provides a limiting fit with the attachment 200, preventing the attachment 200 from impacting the upper cover 20 and causing structural damage.
[0035] In some embodiments, reference may be made to Figure 5 and Figure 6 As shown, a locking member 600 is detachably connected to the end of the second post 320 away from the upper cover 20. The second post 320 passes through the attachment 200 and is connected to the locking member 600. The locking member 600 is axially engaged with the attachment 200 to prevent the attachment 200 from separating from the second post 320. For example, the locking member 600 can be a screw.
[0036] This application also provides a housing assembly, which can be referred to Figure 7 As shown, the housing assembly includes a top cover 20 and a crimper 10 provided in any of the above embodiments, the crimper 10 being mounted on the top cover 20. The crimper 10 rotates with the top cover 20 to the surface of the housing 30 to limit the sleeve on the surface of the housing 30.
[0037] This application also provides a printer, which can be referred to in the embodiments. Figure 8 As shown, the printer includes the aforementioned housing assembly.
[0038] In some preferred embodiments, there are two crimpers 10, which are arranged along the conveying direction of the sleeve to be printed, thereby improving the limiting effect on the sleeve. The printer body 30 has a printing area 31, which is used for printing, that is, printing preset marks on the surface of the sleeve.
[0039] Of the two crimpers 10, one crimper 10 is located near the input port of the printing area 31. A support protrusion 32 is also provided at this input port, which corresponds to and limits the sleeve to be printed by the crimper 10 adjacent to the input port. The support protrusion 32 restricts the installation space of the sleeve, enhances the pressing effect of the limiting member 100 on the sleeve, thereby improving the limiting effect of the crimper 10 on the sleeve and improving the positional stability of the sleeve, ensuring that the sleeve can be input into the printing area 31 for printing according to the preset direction and position.
[0040] When the crimping device 10 also includes a mounting post 300 and an elastic element 400, the mounting post 300 is fixed to the upper cover 20, the limiting element 100 is movably sleeved outside the mounting post 300, the elastic element 400 is sleeved outside the mounting post 300, and a reinforcing rib 500 is fixed between the mounting post 300 and the upper cover 20, and the elastic element 400 is installed between the limiting element 100 and the upper cover 20.
[0041] The limiting member 100 can move axially along the mounting post 300 according to the radial dimension of the sleeve it mates with, adaptively adjusting the position of the limiting member 100 and the upper cover 20. An elastic member 400 is also sleeved outside the mounting post 300. When the elastic member 400 is compressed, it drives the limiting member 100 to move toward the sleeve, so that the limiting member 100 can press against the sleeve and stabilize the position of the sleeve.
[0042] The length of the reinforcing rib 500 of the crimper 10 near the inlet is shorter than the length of the reinforcing rib 500 of the crimper 10 farther from the inlet. (See reference...) Figure 9 As shown, the dashed arrow C indicates the direction of the casing conveying. The front crimper 10 is far from the inlet, while the rear crimper 10 is close to the inlet. The length of the reinforcing rib 500 of the front crimper 10 is greater than that of the rear crimper 10.
[0043] In the structure of the crimper 10, the limiting member 100 moves outside the mounting post 300. When the limiting member 100 abuts against the reinforcing rib 500, the limiting member 100 moves to its limit position. Because the reinforcing rib 500 located at the rear is shorter, the movable distance of the limiting member 100 located at the rear is longer. This reduces the impact of the supporting protrusion 32 on the movable distance of the limiting member 100, and avoids the situation where the supporting protrusion 32 reduces the limiting space corresponding to the sleeve, causing the sleeve to be squeezed and deformed. At the same time, an elastic member 400 is pressed between the limiting member 100 and the upper cover 20. The closer the limiting member 100 is to the upper cover 20, the longer the compression distance of the elastic member 400, the stronger the force of the elastic member 400 on the limiting member 100, and the better the pressing effect of the limiting member 100 on the sleeve. Therefore, even when conveying the same sleeve, the rear limiting member 100 is closer to the top cover 20 than the front limiting member 100, the rear elastic member 400 is compressed over a longer distance, and the pressure exerted by the rear limiting member 100 on the sleeve is greater than that of the front limiting member 100, so as to ensure that the sleeve is input into the printing area 31 for printing in the preset direction and position.
[0044] In some specific embodiments, there are multiple mounting posts 300, and the elastic element 400 is only fitted on some of the mounting posts 300, or the number of elastic elements 400 is the same as the number of mounting posts 300, and each mounting post 300 is fitted with an elastic element 400.
[0045] It should be noted that, in this document, the term "comprising" or any other variation thereof is 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. Without further limitation, 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.
[0046] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
