Description

Technical Field

[0001] The present invention relates to the field of seals, and specifically to a double-opening rolling-brush seal. Background Art

[0002] Today's intelligent seals integrate traditional seals, Internet of Things, and communication technologies, combining machinery, electronics, computer control, and Internet technologies. They can effectively manage seals by seal owners, such as effectively counting the number of times a seal is stamped and the content of the stamping and timely uploading it to the hands of managers, greatly improving non-compliant or illegal acts such as random stamping and forging seals, and ensuring the positive role of enterprise operation safety and stable social economy. However, the above intelligent seals still have the following problems:

[0003] 1. When stamping, it is necessary to dip the seal surface in stamp pad ink, and a stamp pad is required, which is inconvenient to use. The stamp pad ink is also easy to dirty hands or the tabletop. At the same time, it is very difficult to evenly dip the stamp pad ink or stamp oil on the seal surface, so the stamped imprints often appear incomplete or unclear;

[0004] 2. When stamping, the seal surface of the seal is generally fixed, so only one type of imprint can be stamped. If multiple types of imprints need to be stamped, multiple seals need to be used. However, in current life, it is often necessary to use different types of seals to stamp different imprints, so it is very inconvenient to store multiple types of seals;

[0005] 3. For a re-inking mechanism and a seal device in a Chinese patent (application number: 2021109058578), after stamping, it can use an internal reverse mechanism to flip the seal surface back into the seal, becoming a widely used product. However, due to the large flipping amplitude of the seal head, the overall volume of the seal is relatively large, making it inconvenient to carry; in addition, due to its own structural limitations, its seal surface may still be illegally traced, and the security is not high;

[0006] 4. For a portable automatic stamping mechanism in a Chinese patent (application number: 2022213990480), it can clamp seals with different diameters and take out the seals to achieve manual stamping, with great flexibility. And to prevent illegal tracing, it adopts a normally closed switch door structure similar to a rolling shutter door structure. When stamping, the shutter quickly opens and closes quickly after stamping, and at the same time, it realizes applying oil to the seal surface. However, the biggest drawback of this solution is that to ensure compatibility, the seal volume is too large, making it inconvenient to use. Summary of the Invention

The seal can be driven by hand pressure of the stamper through the up-and-down movement of the pressing frame on the supporting frame. During driving, the seal does not flip. When pressing down, the rotating doors that open on both sides are controlled to flip and open respectively for stamping. After stamping, the rotating doors that open on both sides automatically reset and close the seal. Compared with traditional flip-type (inking seals) or other intelligent seals, this structure has the advantages of simple structure, flexible use, small volume, etc. At the same time, it has high security and can effectively solve the phenomenon that seals without flipping the seal surface can be illegally used, making up for the security defects of such devices.

[0034] 4. The structure of the present invention is small in overall dimension and convenient for the operator to use and carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] 1. Press the switch 2 to control the unlocking of the locking device 21. The pin shaft at the end of the electromagnet moves back, so that the pin shaft does not contact the middle shell 4, unlocking and stamping;

[0070] 2. Manually press the upper shell 3. When the upper shell 3 is pressed down, it drives the middle shell 4 to compress the compression spring 9 sleeved outside the guide post. The middle shell 4 moves further downward, thereby driving the lower pressing frame 10 to move downward. When the lower pressing frame 10 moves downward, it will drive the stamp to move downward together. During the entire downward movement, oil dipping and opening of the rotating door 12 will be completed. While the second driving device drives the rolling brush 13 to move. Specifically: when the lower pressing frame 10 is pressed down, it drives the connecting member 104 to rotate through the connecting rod 105. The rotation of the connecting member 104 drives the first transmission gear 179 to rotate, thereby driving the small double gear 183 to rotate. The rotation of the small double gear 183 drives the second transmission gear 182 to rotate and drives the large double gear 181 to rotate. While the large double gear 181 rotates, it drives the rotating wheel 180 to rotate along the large double gear 181. While the rotating wheel 180 rotates, it drives the connected connecting frame 194 and the gear shaft on the connecting frame 194 to move along the U-shaped groove 175. During the movement of the connecting frame 194, it drives the connected fixed frame 193 to drive one end of the central axis of the rolling brush 13 to move along the third stroke groove 178, and the central axis of the other end of the rolling brush 13 moves along the first stroke groove 159 and the second stroke groove 160 through the connected first moving bracket 190. The rolling brush 13 will dip the printing ink on the surface of the stamp;

[0071] On the other side, the rotating door 12 is driven to open by the first driving device. Specifically, when the pressing frame 10 presses down, the connecting rod 105 drives the connecting piece 104 to rotate. The rotation of the connecting piece 104 drives the first gear 162 to rotate, thereby driving the first double gear 163 to rotate. While the first double gear 163 rotates, it drives the second gear 164 to rotate, thereby driving the second double gear 165 to rotate. When the second double gear 165 rotates, it drives the first rack 156 to move to the right and drives the first rack 156 to move to the left through the meshing rotating gear 157. During the movement of the first rack 156 and the second rack 158, the second connecting shafts 122 at both ends of the rotating door 12 are driven to move in the track groove 161, and the first connecting shaft 121 moves in the door opening groove 176, thereby opening the rotating door 12 and exposing the seal from the outlet, and the stamping operation can be performed;

[0072] 3. After the stamping is completed, when the hand releases the upper shell 3, during the upward movement, under the restoring force of the compression spring 9, the upper shell 3 and the middle shell 4 move upward. At the same time, the tension spring is pulled back upward to drive the seal to move upward and reset. The middle shell 4 drives the pressing frame 10 to move upward and raises the seal into the lower shell 5. At the same time, the first gear set and the second gear set will reset to the initial position, closing the rotating door 12 and resetting the rotary brush 13 to its original position, completing the entire reset process;

[0073] 4. Press the switch 2 to control the locking device 21 to lock. The pin shaft at the end of the electromagnet moves towards the middle shell 4, so that the pin shaft contacts the middle shell 4, and the seal can be locked.
