Seal devices can be broadly divided into two categories: one relies on a physical seal, often called a seal locking device; the other does not rely on a physical seal, often called a rotary printer. Seal locking devices manage seals through locking and approval mechanisms; they can only be unlocked and used after authorization, leaving a mark after stamping. Rotary printers, on the other hand, create marks through printing and also require approval.

[0003] The seal locking device includes a bottom shell, a controller, a fingerprint module, a seal driving unit, a locking unit, and a seal; the controller is electrically connected to the fingerprint module and the locking unit; the seal driving unit can drive the seal to move between the locking position and the stamping position, so that the seal can abut against the printing carrier (e.g., a document) to stamp; the locking unit can lock the seal driving unit to prevent the seal driving unit from driving the seal.

[0004] However, the seal locking device can only hold one type of seal, such as the official seal. When the user wants to affix a contract seal or financial seal, the original official seal in the seal locking device needs to be removed and replaced with the contract seal or financial seal. After the user affixes the contract seal or financial seal, the original official seal needs to be replaced again. This results in the user having to frequently disassemble and reassemble the seal, affecting the user experience. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that in the description of this utility model, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no sequential order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "at least one" means one or more, and "multiple" means two or more. The use of the term "may" is intended to indicate that any attribute described that is included in "may" is optional.

[0027] In this embodiment, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0028] like Figures 1 to 4 As shown, this utility model provides a seal locking device, including: a seal driving unit 1 and a seal switching unit 2; the seal switching unit 2 is connected to the seal driving unit 1. When multiple seal units 3 are connected to the seal switching unit 2, the seal switching unit 2 can drive the multiple seal units 3 to move, so that one of the multiple seal units 3 is in the working position.

[0029] In practical implementation, by setting up a stamp driving unit 1 and a stamp switching unit 2, the problem of traditional stamp locking devices being able to accommodate only one type of stamp and causing frequent disassembly and assembly is solved, thereby improving the user experience. The stamp switching unit 2 can be connected to the stamp driving unit 1 and drive multiple stamp units 3 to move. Any stamp unit 3 can be adjusted to a working position for stamping operations. When the user needs to use different stamps, they only need to switch the stamp unit 3 currently in the working position, thus eliminating the need to disassemble or install new physical stamps, simplifying the operation process, and improving the efficiency and convenience of stamp use. In other words, instead of "one machine, one stamp", it is now "one machine, multiple stamps".

[0030] In this embodiment, the stamp driving unit 1 can be based on existing technology; for example, it can be a mechanism capable of reciprocating linear motion. The stamp switching unit 2 can be in the shape of a cube. The stamp unit 3 can be a complete stamp or a stamp body with an imprint face.

[0031] According to one embodiment of the present invention, the stamp switching unit 2 includes a receiving shell 21 and a movable mechanism 22; the receiving shell 21 is connected to the stamp driving unit 1 and has a receiving cavity 210 and a stamp opening 2123; the stamp opening 2123 is located in the working position; the movable mechanism 22 is located inside the receiving shell 21 and is movably connected to the cavity wall of the receiving cavity 210. When multiple stamp units 3 are connected to the movable mechanism 22, the movable mechanism 22 can drive the multiple stamp units 3 to move, so that one of the multiple stamp units 3 is located in the working position, so that its stamp surface is exposed through the stamp opening 2123.

[0032] In practical implementation, by setting up a stamp switching unit 2 that includes a housing 21 and a movable mechanism 22, the function of accommodating and quickly switching multiple stamps in a single device is realized, significantly improving efficiency and convenience. Specifically, the housing 21, as the part connecting the stamp driving unit 1, not only provides space for storing multiple stamp units 3, i.e., the housing cavity 210, but also has an exposed stamp opening 2123 for the currently selected stamp unit 3 to be exposed for stamping. The movable mechanism 22 is cleverly placed inside the housing 21 and can flexibly connect with the cavity wall of the housing cavity 210, ensuring that when multiple stamp units 3 are connected to it, it can drive these stamp units 3 to move and switch their positions. This allows the user to simply rotate the movable mechanism 22 to put the required stamp unit 3 into the working position, thereby achieving the purpose of accurately exposing the stamp face through the exposed stamp opening 2123 for stamping. The entire process does not require disassembling or replacing physical stamps, simplifying the operation process, improving work efficiency, and ensuring the compactness of the structure to enhance the user experience.

[0033] In this embodiment, the housing 21 may be in the shape of a cube.

[0034] According to one embodiment of the present invention, the receiving cavity 210 is spherical; the movable mechanism 22 is rotatably connected to the cavity wall of the receiving cavity 210.

[0035] In practical implementation, by designing the receiving cavity 210 as a spherical shape and allowing the movable mechanism 22 to be rotatably connected to the cavity wall of the receiving cavity 210, parts such as rotating shafts or bearings are eliminated, thereby reducing space occupation and lowering costs. Simultaneously, the movable mechanism 22 can rotate freely within the receiving cavity 210, ensuring that users can select the desired stamp unit 3 according to their needs. The stamping operation can then proceed by exposing the stamp unit 3 through the stamp opening 2123, making the entire process simple and convenient.

[0036] In this embodiment, the shape of the movable mechanism 22 is approximately the same as the shape of the receiving cavity 210. The movable mechanism 22 is located in the receiving cavity 210. For example, the movable mechanism 22 can be a shape formed by cutting off a portion from each end of a sphere.

[0037] According to one embodiment of the present invention, the receiving shell 21 includes a first shell 211 and a second shell 212; the first shell 211 is located above the second shell 212 and is detachably connected to the second shell 212; the first shell 211 has a first sub-cavity 2111 and a first opening 2112; the first opening 2112 is located at the connecting end of the first shell 211; the second shell 212 has a second sub-cavity 2121, a second opening 2122 and an exposure opening 2123; the first sub-cavity 2111 and the second sub-cavity 2121 surround to form a receiving cavity 210; the second opening 2122 is located at the upper end of the second shell 212 and communicates with the first opening 2112; the exposure opening 2123 is located at the lower end of the second shell 212.

[0038] In practice, by designing the housing 21 as a detachable first housing 211 and second housing 212 structure, it is convenient to inspect, maintain or replace the internal moving mechanism 22 or the stamp unit 3.

[0039] In this embodiment, the first shell 211 may be referred to as the upper shell, and the second shell 212 may be referred to as the lower shell. The first shell 211 and the second shell 212 can be fastened together. The first setting opening 2112 may be located at the lower end of the first shell 211. The second setting opening 2122 may be located at the upper end of the second shell 212. The exposing opening 2123 may be circular and located at the lower end of the second shell 212.

[0040] According to one embodiment of the present invention, the surface of the active mechanism 22 has a plurality of stamp receiving holes 221, and a stamp receiving hole 221 can accommodate a stamp unit 3.

[0041] In practice, the stamp locking device is designed with multiple stamp receiving holes 221 on the surface of the movable mechanism 22. Each stamp receiving hole 221 can accommodate one stamp unit 3, which not only improves space utilization, but also avoids interference between the movable mechanism 22 and the receiving shell 21 when the movable mechanism 22 rotates.

[0042] In this embodiment, there may be two stamp receiving holes 221, which are arranged opposite to each other at both ends of the movable mechanism 22. The stamp receiving holes 221 may be circular, and the stamp unit 3 may be embedded in the stamp receiving hole 221.

[0043] According to one embodiment of the present invention, it further includes a bottom shell 4, which has an inner cavity, a through hole 41, and a stamp outlet 42; the through hole 41 is located at the upper end of the bottom shell 4; the stamp outlet 42 is located at the lower end of the bottom shell 4; the stamp switching unit 2 is located in the inner cavity; the stamp driving unit 1 is disposed at the through hole 41 and can extend into the through hole 41, and is connected to the receiving shell 21, and the stamp driving unit 1 can drive the receiving shell 21 to perform reciprocating linear motion in the vertical direction.

[0044] In practice, the bottom shell 4 mainly serves to support the seal driving unit 1.

[0045] According to one embodiment of the present invention, the stamp driving unit 1 includes a support tube 11 and a pressure rod 12; the support tube 11 is located at the upper end of the bottom shell 4 and is arranged vertically at the through hole 41; the pressure rod 12 is slidably inserted into the support tube 11 in the vertical direction, and the lower end of the pressure rod 12 is connected to the receiving shell 21.

[0046] In practice, the pressure rod 12 can move up and down in a reciprocating motion, which is equivalent to the support tube 11. The movement of the pressure rod 12 can drive the stamp switching unit 2 to move in order to perform the stamping action.

[0047] According to one embodiment of the present invention, it further includes a limiting unit 5 and an elastic reset unit 6; the limiting unit 5 is disposed at the upper end of the support tube 11; the elastic reset unit 6 is sleeved on the support tube 11 and the pressure rod 12, and is sandwiched between the upper end of the bottom shell 4 and the lower end of the limiting unit 5, so that the pressure rod 12 can be reset.

[0048] In practice, the elastic reset unit 6 is sleeved on the support tube 11 and the pressure rod 12, and is located between the upper end of the bottom shell 4 and the lower end of the limiting unit 5. It can automatically reset the pressure rod 12 to its initial position (locked position) after completing one stamping action, ensuring the consistency and continuity of operation. This design simplifies the user's operation steps, so that the user does not need to manually pull the pressure rod 12 upward after each stamping to prepare for the next stamping operation.

[0049] In this embodiment, the limiting unit 5 may be plate-shaped; the elastic reset unit 6 may be a conventional compression spring.

[0050] According to one embodiment of the present invention, the stamp unit 3 includes an imprint.

[0051] In practice, because the stamps are small in size and have no handles, multiple stamps can be compactly placed in the stamp switching unit 2, thereby saving space and improving integration.

[0052] In this embodiment, the mold, or mold body, has an end with a printing surface for displaying printed text or graphics.

[0053] According to one embodiment of the present invention, the plurality of stamp units 3 include a first stamp unit 3 and a second stamp unit 3, wherein the stamp surface of the first stamp unit 3 is different from the stamp surface of the second stamp unit 3.

[0054] In practice, by integrating seal units 3 with different seal faces, users can quickly switch between different seals, such as official seals, contract seals, or financial seals, according to their actual needs, without having to go through a cumbersome disassembly and installation process.

[0055] According to one embodiment of the present invention, the stamp locking device may include a bottom shell 4, a stamp driving unit 1, a limiting unit 5, an elastic reset unit 6, a locking unit 7, a stamp switching unit 2, a controller 8, and a fingerprint module 9; the bottom shell 4 has an inner cavity, a through hole 41, and a stamp outlet 42; the through hole 41 is located at the upper end of the bottom shell 4; the stamp outlet 42 is located at the lower end of the bottom shell 4; the stamp switching unit 2 is located in the inner cavity. The stamp driving unit 1 includes a support tube 11 and a pressure rod 12; the support tube 11 is located at the upper end of the bottom shell 4 and is arranged vertically at the through hole 41, that is, the support tube 11 can pass through the through hole 41, and the bottom side wall of the support tube 11 has a downwardly extending groove; the pressure rod 12 is slidably inserted into the support tube 11 in the vertical direction, and the lower end of the pressure rod 12 can pass through the through hole 41 and connect to the receiving shell 21; a locking strip is provided on the side wall of the pressure rod 12, and the locking strip is located in the groove. The limiting unit 5 is located at the upper end of the support tube 11. The elastic reset unit 6 is sleeved on the support tube 11 and the pressure rod 12, and is clamped between the upper end of the bottom shell 4 and the lower end of the limiting unit 5, enabling the pressure rod 12 to reset. The locking unit 7 can be a solenoid valve. The valve stem of the solenoid valve can move linearly in the horizontal direction. When the locking unit 7 is in the locked state, the elastic reset unit 6 is in the extended state, and the valve stem of the solenoid valve can extend into the channel, with the lower end of the locking bar abutting the upper end of the valve stem. When the locking unit 7 is in the unlocked state, the elastic reset unit 6 is in the compressed state, the valve stem of the solenoid valve retracts, and the locking bar can slide freely in the channel. The controller 8 is electrically connected to the fingerprint module 9 and the locking unit 7.

[0056] Working principle:

[0057] Before stamping, the user must first confirm whether the stamp face 2123 is the one they need. If not, they can rotate the movable mechanism 22 to switch to the desired stamp face. After the stamp face is switched, the stamping operation can begin. The user first performs fingerprint verification. After successful fingerprint verification, the controller 8 will control the locking unit 7 to be in the unlocked state. At this time, the user presses down the pressure rod 12, which moves downward. The downward movement of the pressure rod 12 will drive the stamp switching unit 2 to move downward. When the stamp switching unit 2 moves downward to the stamp face 2123, the stamp face is exactly aligned with the document to be stamped, thus completing the stamping. After stamping, the user can release the force. At this time, the elastic reset unit 6 will cause the pressure rod 12 to move upward to reset the pressure rod 12, and the controller 8 can control the locking unit 7 to be in the locked state.

[0058] The above are only a few embodiments of this utility model. Those skilled in the art can make various modifications or variations to the embodiments of this utility model based on the content disclosed in the application documents without departing from the spirit and scope of this utility model.
