Description

Technical Field

[0001] This utility model relates to the field of seal technology, and in particular to a multi-faceted self-inking seal. Background Technology

[0002] A self-inking stamp is an automatic inking stamp that integrates the stamp face and the ink pad into one unit. It achieves the linkage between stamping and ink return through a built-in mechanical structure. It features convenient operation, clear imprints, and strong applicability, and is widely used in business offices, document management, and industrial signage.

[0003] A self-inking stamp disclosed in Chinese Patent Publication No. CN209505252U describes a self-inking stamp where pressing the top of the stamp causes the printing surface to extend downwards against spring resistance, contacting the paper to complete the imprint. Releasing the pressure causes the spring to spring back, ensuring the printing surface makes close contact with the internal self-inking pad, preparing for the next imprint. However, based on existing self-inking stamps and related technologies, most are single-sided designs, meaning one stamp can only correspond to one fixed content. If different content needs to be imprinted, multiple stamps are required, increasing carrying and management costs and increasing the risk of confusion or omission. Furthermore, some replaceable-sided self-inking stamps require manual disassembly of the inkpad and replacement of the printing surface module, involving complex procedures such as tightening screws and removing clips. After switching, the position needs to be recalibrated, which can lead to blurry imprints due to positioning errors. Some designs even require replacing the entire stamp body, making quick switching impossible. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a multi-sided self-inking stamp.

[0005] The purpose of this utility model is achieved through the following technical solution: a multi-sided self-inking stamp, comprising a stamp shell, a movable frame slidably disposed inside the stamp shell, a polygonal self-inking component disposed inside the movable frame, a plurality of stamp seats disposed on the outer surface of the polygonal self-inking component, an adjustment component disposed on the movable frame for controlling the polygonal self-inking component to flip over, a drive component disposed on the side of the stamp shell for causing the adjustment component to operate when the movable frame extends or retracts, an elastic element disposed between the top of the movable frame and the top surface inside the stamp shell, and an ink pad for replenishing ink to the stamp fixedly mounted at the bottom of the stamp shell.

[0006] Preferably, the adjustment assembly includes a rotating shaft rotatably connected to the movable frame, an eccentric member fixedly provided at one end of the rotating shaft located inside the movable frame, and an insert rod eccentrically provided on the side of the eccentric member away from the rotating shaft, the insert rod being fixedly connected to the eccentric member.

[0007] Preferably, the polygonal printout has an insertion hole corresponding to the position of the insertion rod, and the end of the insertion rod away from the eccentric member is provided with a snap-fit ​​component for allowing the polygonal printout to rotate with the insertion rod.

[0008] Preferably, the snap-fit ​​assembly includes a mounting groove formed at the end of the rotating shaft, and a snap-fit ​​member is hinged inside the mounting groove via a spring rotating shaft. The polygonal return stamp has snap-fit ​​slots in the same number as the stamp holder, corresponding to the position of the snap-fit ​​member.

[0009] Preferably, the drive assembly includes a rack fixedly mounted on the bottom of the stamp housing, and a gear is fixedly provided at the end of the rotating shaft away from the eccentric member, the gear meshing with the rack.

[0010] Preferably, the movable frame has a rotating hole corresponding to the position of the rotating shaft, and the rotating shaft is connected to the rotating hole through a bearing.

[0011] Preferably, the outer surface of the snap-fit ​​component is formed with rounded corners.

[0012] Beneficial effects:

[0013] This multi-faceted self-inking stamp, through the setting of adjustment components, drive components, and snap-fit ​​components, achieves the effect of precise positioning after the printing face is flipped by the coordination of the adjustment components and drive components. It can quickly switch the polygonal self-inking piece without the need for tools. It can support switching a single printing face, or directly replace a printing face or replace the entire polygonal self-inking piece. Compared with traditional single-faced stamps, it significantly increases the diversity of the content that can be printed. One stamp can replace multiple traditional stamps, reducing carrying and management costs. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0028] like Figures 1 to 10As shown, a multi-sided self-inking stamp includes a stamp shell 1, a movable frame 2 slidably disposed inside the stamp shell 1, a polygonal self-inking component 3 disposed inside the movable frame 2, a plurality of stamp seats 4 disposed on the outer surface of the polygonal self-inking component 3, an adjustment component 5 disposed on the movable frame 2 for controlling the polygonal self-inking component 3 to flip over, a drive component 6 disposed on the side of the stamp shell 1 for causing the adjustment component 5 to operate when the movable frame 2 extends or retracts, an elastic element 7 disposed between the top of the movable frame 2 and the top surface inside the stamp shell 1, and an ink pad 8 for refilling the stamp with ink fixedly mounted on the bottom of the stamp shell 1.

[0029] Adjustment component 5 includes a rotating shaft 501 rotatably connected to the movable frame 2. The movable frame 2 has a rotating hole 201 corresponding to the position of the rotating shaft 501. The rotating shaft 501 is connected to the rotating hole 201 through a bearing. By using the bearing, the friction force when the rotating shaft 501 rotates can be reduced, and the stability of the rotating shaft 501 during rotation can be improved. An eccentric member 502 is fixedly provided at one end of the rotating shaft 501 located inside the movable frame 2. An insert rod 503 is eccentrically provided on the side of the eccentric member 502 away from the rotating shaft 501. The drive assembly 6 is fixedly connected to the eccentric part 502. It includes a rack 601 fixedly installed at the bottom of the stamp housing 1. A gear 602 is fixedly provided at the end of the rotating shaft 501 away from the eccentric part 502. The gear 602 meshes with the rack 601. The drive assembly 6 is triggered by sliding the movable frame 2 (or the stamp housing 1). The drive adjustment assembly 5 drives the polygonal return printing part 3 to complete a 180° rotation. The cooperation between the adjustment assembly 5 and the drive assembly 6 can achieve 180° precise positioning of the printing surface and realize the rapid switching of different printing surfaces.

[0030] The polygonal return piece 3 has an insertion hole 301 at the position corresponding to the insertion rod 503. The end of the insertion rod 503 away from the eccentric member 502 has a locking assembly 9 for allowing the polygonal return piece 3 to rotate with the insertion rod 503. The locking assembly 9 includes a mounting groove 901 at the end of the rotating shaft 501. A locking piece 903 is hinged inside the mounting groove 901 via a spring-loaded rotating shaft 902. The polygonal return piece 3 has locking slots 302 at the position corresponding to the locking piece 903, the same number as the stamp holder 4. The outer surface of the locking piece 903 is rounded, allowing it to quickly enter the locking slot 302. The engagement between the locking slot 302 and the locking piece 903 enables the rotating shaft 501 to be controlled... The polygonal return piece 3 is rotated. When it is necessary to switch stamps, by pulling the snap-fit ​​903, the snap-fit ​​903 is disengaged from the snap-fit ​​slot 302, and then the polygonal return piece 3 can be rotated so that the stamp with the desired printing content is facing upwards. Thus, when it is necessary to change the printing content (such as updating text or patterns) or replace worn stamps, it can be disassembled without professional tools, reducing maintenance difficulty and extending the overall service life of the stamp. By utilizing the snap-fit ​​cooperation between the snap-fit ​​component 9 and the polygonal return piece 3, the polygonal return piece 3 can be quickly switched without the aid of tools. It supports switching a single printing surface, or directly replacing a printing surface or the entire polygonal return piece 3 (such as when adding text or patterns), without replacing the entire set of stamps.

[0031] The work process is as follows:

[0032] S1: When in use, by pressing the stamp housing 1, the elastic element 7 will be compressed. Then, by utilizing the cooperation between the gear 602 and the rack 601, when the stamp housing 1 moves downward, the rotating shaft 501 can drive the polygonal return stamp 3 to rotate 180° through the eccentric element 502, the insert rod 503 and the snap-fit ​​assembly 9, so that the stamp inside the stamp seat 4, which was originally facing upward, can perform the stamping work.

[0033] S2: When the stamp housing 1 is released, the elastic force of the elastic element 7 is restored, causing the stamp housing 1 to move upward. Thus, by utilizing the cooperation between the gear 602 and the rack 601, when the stamp housing 1 moves upward, the rotating shaft 501 can drive the polygonal return stamp 3 to rotate 180° through the eccentric element 502, the insert rod 503 and the snap-fit ​​assembly 9, so that the stamp stamped on the polygonal return stamp 3 contacts the ink pad 8, thereby completing the automatic ink replenishment work.

[0034] S3: Each side of the polygonal printing piece 3 (such as a regular square prism or a regular hexagonal prism) can be independently equipped with a stamp holder 4, so that stamps with various printing contents can be installed.

[0035] S4: When it is necessary to switch stamps, pull the snap-fit ​​903 to disengage it from the snap-fit ​​slot 302, and then control the polygonal return stamp 3 to rotate so that the stamp with the desired content is facing upwards. Thus, when it is necessary to change the content (such as updating text or patterns) or replace worn stamps, it can be disassembled without professional tools, reducing maintenance difficulty and extending the overall service life of the stamp.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
