Description

Technical Field

[0001] This utility model belongs to the field of intelligent signature technology, and in particular relates to an intelligent signature locking mechanism. Background Technology

[0002] Smart signatures combine seal components with mechanized structures and use the Internet of Things to control these structures to record information such as the user, time, location, and content of the seal, thus achieving full-process risk control.

[0003] The mechanized structure of smart seals includes a locking mechanism. This mechanism helps to lock the smart seal when not in use, preventing unauthorized use. Most existing locking mechanisms use a flap structure as a barrier to isolate the seal from the outside space. The flap structure is fixed mainly by an electromagnet controlling a pin to achieve locking. However, this type of structure mainly uses a spring to provide support. After long-term use, the spring's support becomes insufficient, causing the locking function to deteriorate and fail to achieve the purpose of locking. Utility Model Content

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This utility model embodiment provides an intelligent signature locking mechanism, such as Figures 1-6As shown, the intelligent signature locking mechanism comprises a signature platform 300 mainly consisting of a signature housing 110, a touch screen 120, a signature platform 300, and a locking mechanism. The intelligent signature locking mechanism includes:

[0034] The guide slide 200 and the signature platform 300 are provided with a sliding guide groove 210 for sliding guidance of the signature platform 300; the signature platform 300 is used to fix the signature, so when the signature platform 300 slides along the sliding guide groove 210, the signature will move and complete the stamping.

[0035] The locking plate includes a flip plate 410 and a locking mechanism 420. The flip plate 410 is rotatably connected to the guide slide 200, and the locking mechanism 420 is disposed on the inner wall of the signature shell 110.

[0036] The locking mechanism 420 includes a base 421 and a support plate 422. The support plate 422 is rotatably connected to the base 421. The end of the flip plate 410 away from the guide slide 200 is engaged with the support plate 422 and the base 421. When the flip plate 410 is engaged with the support plate 422 and the base 421 and cannot be disengaged, it will prevent the movement of the signature platform 300, and the stamping action cannot be completed. When the base 421 and the support plate 422 are in contact, they are magnetically connected. The magnetic connection is used to operate the support plate 422 to restrict the movement of the flip plate 410.

[0037] In this embodiment, the signature platform 300 includes a side plate 301 and a horizontal plate 302 and a connecting plate 303 connected between the side plates 301; the horizontal plate 302 is used to fix the seal, while the connecting plate 303 enhances the connection between the side plates 301. The side plate 301 is provided with a slider 320 and a push block 330. The slider 320 slides in the sliding guide groove 210, and the push block 330 extends out of the signature shell 110 as a manual pressing component.

[0038] In this application, the locking plate uses the flipping function of the support plate 422 in conjunction with the base 421 to limit the flipping plate 410. The support of the support plate 422 enhances the limiting ability of the flipping plate 410, improves the stability of the structure, avoids the possibility of damage caused by insufficient support in traditional structures and the possibility of damage caused by violent operation during operation, ensures the stability of the equipment in the locked state, and reduces the possibility of damage to the equipment by violent operation.

[0039] In a preferred embodiment of this invention, the flip plate 410 is provided with a shaft hole, which is fitted onto a deflection shaft 220 provided on the guide slide 200, and a torsion spring is provided on the deflection shaft 220.

[0040] In this embodiment, the torsion spring is nested on the deflection shaft 220. One end of the torsion spring is connected to the guide slide 200, and the other end is connected to the flip plate 410. The assembly principle of the torsion spring is described in detail here with reference to the prior art.

[0041] The torsion spring is used to help the stamp reset after the stamping operation. After the stamping operation is completed on the stamping platform 300, when it moves upward again under the action of the main traction spring (not shown in this application) on the stamping housing 110, it will move synchronously with the side plate 301 to block the bottom of the stamping platform 300. The main traction spring is connected between the stamping housing 110 and the stamping platform 300. It mainly helps the stamping platform 300 to move upward again after the stamping operation. The specific setting position is the same as the existing technology. This application mainly focuses on the locking mechanism and will not elaborate on it in detail.

[0042] In a preferred embodiment of this invention, the base 421 is provided with an ear seat 4211, and the support plate 422 is provided with a rotating shaft at both ends. The rotating shaft is mounted on the ear seat 4211 and a torsion spring is provided on the rotating shaft. The base 421 is also provided with an upper baffle 4212. After the flip plate 410 is deflected, it abuts against the upper baffle 4212, and the support plate 422 abuts against the end face of the flip plate 410 away from the upper baffle 4212.

[0043] After the support plate 422 is deflected, it contacts and connects with the end face of the ear seat 4211 on the base 421. The end face of the ear seat 4211 on the base 421 is also provided with a first electromagnetic limiter 431. The base 421 is limited and connected to the support plate 422 through the first electromagnetic limiter 431. The locking plate also includes a second electromagnetic limiter 432. The second electromagnetic limiter 432 is provided on the inner wall of the seal housing 110. The support plate 422 contacts and connects to the seal housing 110 through the second electromagnetic limiter 432.

[0044] In this embodiment, a reset torsion spring is provided on the rotating shaft. The reset torsion spring structure on the rotating shaft is the same as the torsion spring structure described above. Here, the reset torsion spring helps the support plate 422 to generate a deflection force that contacts the base 421. Here, the function of the second electromagnetic limiter 432 is to align and attract and limit the support plate 422 when it comes into contact with the seal housing 110 under the push of the flip plate 410. Before the flip plate 410 returns to the base 421, it prevents the support plate 422 from flipping prematurely and causing the flip plate 410 to fail to reset. Here, the function of the first electromagnetic limiter 431 is to prevent the support plate 422 from rotating, thereby achieving the purpose of restricting the movement of the flip plate 410.

[0045] In a further preferred embodiment of the present invention, the guide slide 200 is further provided with a power failure protection mechanism, which includes a limit block 510, a third electromagnetic limiter 520, a reset spring 530 and an insertion block 540.

[0046] The guide slide 200 has a cavity inside, the third electromagnetic limiter 520 is disposed in the cavity, the insertion block 540 is magnetically connected to the third electromagnetic limiter 520, the reset spring 530 is nested outside the insertion block 540 and the third electromagnetic limiter 520, and the limiter block 510 is disposed at the end of the insertion block 540 away from the third electromagnetic limiter 520.

[0047] When the magnetism between the insertion block 540 and the third electromagnetic limiter 520 is eliminated, the insertion block 540 moves away from the third electromagnetic limiter 520 under the action of the reset spring 530. The bottom of the sliding guide groove 210 is provided with a port that communicates with the cavity. The limiter block 510 extends from the cavity into the sliding guide groove 210 through the port to block the sliding of the slider 320.

[0048] In this embodiment, the power failure protection mechanism serves as a temporary locking structure. Before power is lost, the power failure protection mechanism will release the limiting block 510 to extend into the sliding guide groove 210, preventing the slider 320 from moving. This structure is only used as a temporary emergency locking device to prevent the device from being misused after a power failure; it is not used as a commonly used limiting structure. When the power is insufficient, the user will be notified in time to replenish the power.
