DETAILED DESCRIPTION

[0031] Please refer to Figures 1-3The double-sided turnover type mechanical counting anti-fake seal in the embodiment of the application comprises an outer shell body 1, the outer shell body 1 is a three-dimensional structure with a waist-shaped cross section, the upper and lower ends of the outer shell body 1 are both waist-shaped, the two sides of the outer shell body 1 are arc surfaces, the front and rear sides of the outer shell body 1 are planes, a ring-shaped cavity 11 is embedded in the inner part of the outer shell body 1, a first through hole 12 is symmetrically and throughly arranged at the center of the front and rear ends of the outer shell body 1, the first through hole 12 is communicated with the ring-shaped cavity 11, a seal 2 is rotatably arranged in the ring-shaped cavity 11, a sleeve 4 is fixedly and peripherally sleeved on the outer shell body 1, the seal 2 comprises a partition plate 21, the two ends of the partition plate 21 are fixedly and symmetrically connected with barrel sleeves 22, a character seal 23 is slidingly and matchingly arranged in one of the barrel sleeves 22, a number seal 24 is slidingly and matchingly arranged in the other barrel sleeve 22, springs are connected between the character seal 23, the number seal 24 and the barrel sleeves 22, rotating shafts 28 that are rotatably connected with the sleeve 4 are symmetrically and connected on the two sides of the partition plate 21, strip-shaped guide rails 25 are throughly arranged at positions opposite to the rotating shafts 28 on the two side edges of the barrel sleeves 22, first handle protrusions 26 that are slidingly matched with the strip-shaped guide rails 25 are fixedly and connected on the two sides of the character seal 23, second handle protrusions 27 that are slidingly matched with the other strip-shaped guide rails 25 are fixedly and connected on the two sides of the number seal 24, an output hole that is communicated with the ring-shaped cavity 11 is throughly arranged at the lower end of the outer shell body 1, and a rotating assembly 5 that is drivingly connected with the rotating shafts 28 is mounted on the sleeve 4.

[0032] Preferably, the strip-shaped guide rails 25 are arranged along the axial direction of the barrel sleeves 22, the ends of the first handle protrusions 26 and the second handle protrusions 27 are located in the first through hole 12, the midpoint of the line connecting the first handle protrusions 26 and the second handle protrusions 27 coincides with the center of the first through hole 12, the rotating shafts 28 are located at the center of the first through hole 12, and the shape of the ring-shaped cavity 11 can be selected as the track formed by the rotation of the character seal 23, the barrel sleeves 22, the partition plate 21 and the number seal 24 through the rotating shafts 28.

[0033] In use, the rotating component 5 drives the rotating shaft 28 to rotate, allowing the text stamp 23 or the number stamp 24 to be rotated to face the output hole as needed. The text stamp 23 and the number stamp 24 have the same shape. The end face of the text stamp 23 is engraved with the name of the company or organization, while the end face of the number stamp 24 is embedded with a mechanical counter. After the text stamp 23 or the number stamp 24 is aligned with the output hole, it can be pushed out of the output hole by sliding on the bar guide rail 25 via the first handle protrusion 26 or the second handle protrusion 27. The stamping process involves rotating a hole to complete the stamping action. After stamping one side, rotating the rotating component 5 will rotate the other side to the same position, thus completing the stamping action at the same location. This allows each stamping action to correspond to a digital stamp 24. The digital stamp 24 uses an irreversible mechanical counter, and a five-digit code digital stamp 24 can only work a maximum of 99,999 times. Each work is recorded in the back-end ledger, allowing for precise tracing back to the responsible person, thereby avoiding unnecessary losses caused by untraceable responsibility. Since the text stamps 23 and 4 are produced from the same angle after being flipped, if criminals attempt to use two stamps to simulate the trajectory and tamper with the matching text stamp 23 and digital stamp 24, the back-end ledger record becomes crucial. This is because the number has been recorded in the back-end by the responsible person, the company's legal representative, and the approver. Therefore, mismatched numbers and stamped content will not be recognized. This design makes it more convenient, flexible, and easy to trace during use.

[0034] Among them, such as Figure 1 As shown, base rods 16 are symmetrically connected to both sides of the lower end of the outer casing 1. Washers 17 are fixedly connected between the base rods 16. The washers 17 are positioned opposite to the output holes and are sized to match. In use, the washers 17 can be pressed and aligned at the position to be stamped. The text stamp 23 or the number stamp 24 can be driven by the first handle protrusion 26 or the second handle protrusion 27 to complete the stamping action. This makes the output more stable and the stamp position more accurate.

[0035] like Figures 1-5As shown, the first through hole 12 is embedded with a sliding groove 14 at the lower end of the inner side, which extends vertically downward and penetrates the lower end of the outer shell 1. The sliding groove 14 and the first handle protrusion 26 and the second handle protrusion 27 are slidingly fitted. The outer shell 1 is embedded with a sliding groove 14 at the side, which is communicated with the strip-shaped track groove 13. The width of the sliding groove 14 is greater than that of the strip-shaped track groove 13. The sliding groove 14 can facilitate manual pinching of the first handle protrusion 26 or the second handle protrusion 27. Further, the sleeve 4 is sleeved on the periphery of the first through hole 12, and the lower side of the sleeve 4 is embedded with an opening 41. The opening 41 facilitates the exposure of the first handle protrusion 26 or the second handle protrusion 27, thereby facilitating manual operation. The sleeve 4 is further provided with a through groove 42 at both sides, and the outer shell 1 at the opposite position of the through groove 42 is embedded with a pressing assembly 3. When the seal 23 and the number seal 24 are rotated by 90°, pressing the pressing assembly 3 can supplement the ink on the surface of the seal 23 and the number seal 24. The sleeve 4 can not only seal the first through hole 12, but also facilitate the installation and rotation of the rotating shaft 28, and will not affect the rotation of the first handle protrusion 26 and the second handle protrusion 27.

[0036] Further, as shown in Figures 4-6 The second handle protrusion 27 is rotatably provided with a rotating ring 2701 around the periphery. The rotating ring 2701 is fixedly connected with a transmission gear 2702 near one side of the strip-shaped guide rail 25 around the periphery. The sliding groove 14 is embedded with a side transmission groove 15 at both sides opposite to the transmission gear 2702. One side (preferably the right side) of the side transmission groove 15 is provided with a rack. The rack and the transmission gear 2702 are in meshing transmission. The second handle protrusion 27 is fixedly connected with a ratchet wheel 2703 inside the rotating ring 2701. The rotating ring 2701 is rotatably connected with a clamping plate 2704. The clamping plate 2704 and the rotating ring 2701 are connected with a torsional spring. Through the cooperation of the rotating ring 2701, the transmission gear 2702, the ratchet wheel 2703 and the clamping plate 2704, one-way transmission between the second handle protrusion 27 and the transmission gear 2702 can be realized. The second handle protrusion 27 and the mechanical counter in the number seal 24 are in transmission connection. The second handle protrusion 27 moves down in the sliding groove 14 once (the number seal 24 realizes seal action once), and then the second handle protrusion 27 can drive the mechanical counter to increase the code once through the rotation of the transmission gear 2702. When the second handle protrusion 27 moves up, the code number of the mechanical counter remains unchanged. Through such a design, the code number of the number seal 24 is irreversible, and the code number can be increased synchronously with each seal action.

[0037] Among them, as shown in Figure 10As shown, the pressing assembly 3 includes a sliding block 31 slidingly embedded in the side of the outer shell 1, the sliding block 31 is connected with an ink pad 33 near the end of the annular cavity 11, and spring grooves 32 for connecting with springs in the outer shell 1 are symmetrically embedded on both sides of the sliding block 31. The rotating assembly 5 can drive the rotating shaft 28 to rotate by a fixed angle, preferably a right angle and a flat angle. When the rotating assembly 5 rotates by a right angle, the ink pad 33 can be pressed to contact the end of the character seal 23 and the number seal 24 by pressing the sliding block 31, and the ink pad can be supplemented flexibly according to needs. When the rotating assembly 5 rotates by a flat angle, the character seal 23 or the number seal 24 can be selected to be aligned with the output hole, so that the character seal 23 or the number seal 24 can be printed according to needs. The ink supplement is simple and convenient, and the use is flexible and convenient.

[0038] As shown in the figure, Figures 7-9 As shown, the rotating assembly 5 includes a fixed cylinder 51 fixedly connected in the sleeve 4, a stepped groove 52 is embedded at the end of the fixed cylinder 51 away from the rotating shaft 28, a second through hole 53 is through the center of the stepped groove 52, a knob 55 is attached to one side of the fixed cylinder 51 away from the rotating shaft 28, a stepped protrusion 56 and a sliding sleeve 57 are sequentially connected to one side of the knob 55 facing the fixed cylinder 51, the stepped protrusion 56 corresponds to the stepped groove 52, the sliding sleeve 57 slides through the second through hole 53, a connecting rod 59 is slidingly connected to one end of the sliding sleeve 57 away from the stepped protrusion 56, one end of the connecting rod 59 is connected to the sliding sleeve 57 through a spring, and the other end is fixedly connected to the rotating shaft 28. Further, a limiting groove 54 is embedded on the opening side of the fixed cylinder 51, and the limiting grooves 54 are respectively arranged at 0°, 90° and 180°, and a limiting protrusion 58 corresponding to the limiting groove 54 is fixedly connected to one side of the sliding sleeve 57. Preferably, an identification 5501 is embedded on the surface of the knob 55, a plurality of guide inner grooves 5701 are embedded on the inner wall of the sliding sleeve 57, a guide rib 5901 slidingly matched with the guide inner grooves 5701 is fixedly connected to the outer wall of the connecting rod 59, and the guide inner grooves 5701 and the guide rib 5901 are both arranged along the axial direction of the sliding sleeve 57. The identification 5501 can mark 0° and 180°, that is, the directions of the character seal 23 and the number seal 24, and it is also convenient to observe the directions of the character seal 23 and the number seal 24 when they rotate by a right angle.

[0039] When using, first pull out the knob 55, the knob 55 drives the sliding sleeve 57 to slide relative to the connecting rod 59, in the process of elastic stretching, the limiting protrusion 58 is separated from the cooperation between the limiting groove 54, according to the needs, can be rotated 0°, 90°, 180°, so that the text seal 23 or the digital seal 24 is opposite to the output hole, or the text seal 23 and the digital seal 24 are aligned and pressed to the assembly 3, the use is flexible and convenient, the rotation angle of the text seal 23 and the digital seal 24 is fixed, and the limiting is stable.
