Description

Technical Field

[0001] The invention relates to the field of seals, and in particular to a smart seal. Background Art

[0002] In the existing seal technology, it is easy for seals to be stolen and replaced maliciously, which will infringe the rights and interests of the seal owner. Therefore, some anti-theft seals have appeared on the market.

[0003] For example, a smart seal disclosed in the patent application with publication number 207697300U includes a housing and a motor sleeve arranged in the housing, a motor is installed in the motor sleeve, and the motor is a stepper motor. The motor shaft of the stepper motor is connected to the sliding sleeve below the motor sleeve, and the sliding sleeve is fixedly connected to the slider below it. The bottom surface of the slider is provided with a seal face for stamping. When the motor shaft is extended according to a predetermined stroke, the seal face extends out of the bottom of the housing. When the smart seal is not in use, the seal face is placed in the housing and cannot effectively touch the document to be stamped, so as to achieve the purpose of not being able to use the seal at will. When the seal needs to be used, the user starts the motor in the seal through authorization, and under the drive of the motor, the seal face is extended out of the housing, so that the seal can be used for stamping.

[0004] This seal solves the authorization problem very well, but it does not take into account its usage after authorization. Once authorized, the seal may be replaced by someone else, or even used multiple times, and it is unknown whether it will be used for other agreements. The usage status cannot be fed back to the manager in a timely manner, which poses certain risks. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a smart seal that can better prevent the seal from being stolen.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A smart seal, comprising

[0008] case;

[0009] A stamping module installed at one end of the housing;

[0010] An ink pad module installed in the housing is used to provide ink pad to the stamping module;

[0011] A counting module installed at one end of the housing away from the stamping module, used for counting the number of stamping times of the stamping module;

[0012] A locking module installed in the housing is used to lock the stamping module to a state where stamping is impossible;

[0013] The control module installed in the housing is used to control the locking module to switch between the two states of locking and unlocking the stamping module.

[0014] By adopting the above technical solution, when the seal is needed, an unlocking signal is first sent to the control module to unlock the locking module, and then the stamping module is in a state where the seal can be stamped. After each stamping, the counting module will count the times until the initial set times are used up. The counting module outputs a signal to the control module, so that the control module controls the locking module to switch to the state of locking the stamping module, thereby completing the requirement of safe stamping.

[0015] The present invention is further configured as follows: the stamping module includes a shell, a red seal component rotatably connected to the shell, and a guide drive component for driving the red seal component to rotate, the guide drive component includes a guide sleeve slidably connected to one end of the shell, a force exchange component arranged on the guide sleeve for converting the moving pair of the guide sleeve into the rotating pair of the red seal component, and a reset spring for connecting the guide sleeve and the shell, and the reset spring gives a connecting force to the guide sleeve parallel to the axial direction of the shell.

[0016] By adopting the above technical solution, in the initial state, the red seal assembly is located at the upper end of the guide sleeve and the red seal body is in a state of facing away from the abutment plate. At this time, since the red seal body is in a state of facing away from the abutment plate, that is, facing the inside of the shell, outsiders cannot see the contents of the red seal book, which is safer.

[0017] When stamping, push the shell downward to make it slide relative to the guide sleeve. Under the action of the force exchange component, the red seal body rotates to a state facing the plane to be stamped. Then continue to push the shell downward until the red seal body abuts against the plane to be stamped, and the stamping is completed. When the shell slides relative to the guide sleeve, the reset spring is compressed. After the stamping is completed, the force applied to the shell is removed, and the guide sleeve slides relative to the shell under the action of the reset spring and resets to the initial state. In this process, the red seal component is rotated to a state facing the inside of the shell to ensure safety.

[0018] The present invention is further configured as follows: a rotating shaft is fixedly provided at both ends of the red seal component along its radial direction, the rotating shaft is rotatably connected to the shell and fixedly connected to the shell along its axial direction, the force change component includes a guide groove opened on the side wall of the guide sleeve along the axial direction of the guide sleeve, two guide grooves are opened, and one rotating shaft corresponds to one guide groove, the rotating shaft passes through the guide groove and is slidably connected to the guide groove, the force change component also includes a gear fixedly sleeved on the rotating shaft and a rack fixedly installed on the guide groove along the length direction of the guide groove, the rack is located in the middle of the guide groove and is shorter than the guide groove, and the gear is meshed with the rack.

[0019] By adopting the above technical solution, when the housing slides relative to the guide sleeve, the rotating shaft slides in the guide groove, and due to the cooperation of the gear and the rack, the red seal assembly rotates relative to the housing until the red seal body rotates to a state facing the plane to be stamped or resets to a state facing the inside of the housing, thereby achieving force exchange.

[0020] The present invention is further configured as follows: the upper end of the guide sleeve is closed, a first mounting plate is fixedly disposed in the shell along the horizontal direction of the shell, and the return spring is located between the guide sleeve and the first mounting plate and abuts against the upper end of the guide sleeve and the first mounting plate.

[0021] By adopting the above technical solution, the reset spring can provide the reset force of the guide sleeve more stably, so that after the stamping is completed and the force applied to the shell is removed, the guide sleeve can slide to the initial state relative to the shell.

[0022] The present invention is further configured as follows: the red seal assembly includes an outer mounting seat with a first accommodating groove, an inner mounting seat snap-fitted into the first accommodating groove, and a red seal body internally threadedly connected to a side of the inner mounting seat away from the outer mounting seat, and a rotating shaft is installed at both ends of the outer mounting seat.

[0023] By adopting the above technical solution, the red seal body can be replaced as needed, so that users can replace the seal according to their actual needs, thereby expanding the scope of application of the smart seal.

[0024] The present invention is further configured as follows: the inner mounting seat is detachably connected to the outer mounting seat.

[0025] By adopting the above technical solution, when a different seal needs to be replaced, the inner mounting seat can be directly removed relative to the outer mounting seat, and then the red seal body can be replaced, so that the user can replace the seal according to his or her actual needs.

[0026] The present invention is further configured as follows: the first receiving groove is a circular groove, the outer wall of the inner mounting seat is provided with at least one clamping block, the inner wall of the first receiving groove is provided with a clamping groove corresponding to the clamping block, and one end of the clamping groove is connected to the opening end of the first receiving groove.

[0027] By adopting the above technical solution, the detachable connection between the inner mounting seat and the outer mounting seat is achieved by means of a snap connection, which has a simple structure and is easy to operate.

[0028] The present invention is further configured as follows: the card slot includes a first card slot, a second card slot and a third card slot, the first card slot is opened circumferentially along the inner side of the first accommodating slot, the second card slot is opened at one end of the first card slot and the second card slot is axially arranged along the first accommodating slot to connect to the open end of the first accommodating slot, and the third card slot is opened axially along the first accommodating slot at one end of the first card slot away from the second card slot.

[0029] By adopting the above technical solution, when a different seal needs to be replaced, the inner mounting seat is pulled up relative to the outer mounting seat, and then the inner mounting seat is rotated until the block slides to the end of the first slot corresponding to the second slot, and finally the inner mounting seat is pulled outward to complete the removal of the inner mounting seat. Then align the block of the inner mounting seat with the new red seal installed with the second slot, and then slide the block through the second slot until it enters the first slot. The inner mounting seat is rotated relative to the outer mounting seat, so that the block slides in the first slot to the top of the third slot and is inserted into the third slot. In this way, the inner mounting seat is stably installed in the outer mounting seat, and the replacement is completed.

[0030] The present invention is further configured as follows: at least two clamping grooves are provided along the circumference of the first accommodating groove, and each clamping groove corresponds to a clamping block.

[0031] By adopting the above technical solution, the inner mounting seat can be fixed at multiple points, so that it can be installed more stably in the outer mounting seat.

[0032] The present invention is further configured as follows: a protective cover is detachably connected to one end of the shell, and the protective cover is sleeved outside the guide sleeve and covers the guide sleeve.

[0033] By adopting the technical solution, the guide sleeve can be protected when the stamp is not in use, thereby reducing the probability of damage to the guide sleeve.

[0034] The invention has the following advantages: 1. The stamping times are counted, and the stamp is locked after the counted times reaches a set number, thereby improving the security of the stamp and making it difficult for the stamp to be stolen; 2. When not stamping, the red stamp component faces inward, making it difficult for people to steal the stamp information; 3. It can be applied to red stamps of different sizes and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] Embodiment 1:

[0050] The following is combined with Figure 1-13 This application is described in further detail.

[0051] The embodiment of the present application discloses a smart seal.

[0052] Reference Figure 1 and Figure 2 , a smart seal, comprising:

[0053] Housing 12;

[0054] A stamping module 1 installed at one end of the housing 12;

[0055] The ink pad module 2 installed in the housing 12 is used to provide ink pad to the stamping module 1;

[0056] A counting module 3 installed at one end of the housing 12 away from the stamping module 1, for counting the number of stamping times of the stamping module 1;

[0057] The locking module 4 installed in the housing 12 is used to lock the stamping module 1 to a state where stamping is impossible;

[0058] The control module 5 installed in the housing 12 is used to control the locking module 4 to switch between locking and unlocking the stamping module 1 .

[0059] When the seal is needed, an unlocking signal is first sent to the control module 5 to unlock the locking module 4, and then the stamping module 1 is in a state where the seal can be stamped. After each stamping, the counting module 3 will count the times until the initial set times are used up. The counting module 3 outputs a signal to the control module 5, so that the control module 5 controls the locking module 4 to switch to the state of locking the stamping module 1, and the requirements for safe stamping are met.

[0060] Specifically, refer to Figure 2 and Figure 3 The stamping module 1 includes a red stamp component 6 rotatably connected to the housing 12 and a guide drive component 7 for driving the red stamp component 6 to rotate. In the initial state, the stamp surface of the red stamp component 6 faces the inside of the housing 12 and is in a state where stamping is not possible. When stamping is required, the guide drive component 7 drives the red stamp component 6 to rotate so that the stamp surface of the red stamp component 6 faces outward, so that stamping can be performed.

[0061] Reference Figure 3 The red seal assembly 6 includes an outer mounting seat 9 with a first receiving groove 8, an inner mounting seat 10 mounted in the first receiving groove 8, and a red seal body 11 connected to the inner mounting seat 10 on a side away from the outer mounting seat 9 by internal threads. Rotation shafts 19 are fixedly provided at both ends of the outer mounting seat 9 along the radial direction thereof, and the rotation shaft 19 is rotationally connected to the housing 12 and fixedly connected to the housing 12 along the axial direction thereof. The outer mounting seat 9 is rotationally connected to the housing 12 through the rotation shaft 19.

[0062] Reference Figure 2 and Figure 3 The housing 12 is fixedly provided with a first mounting plate 13 arranged in the horizontal direction of the housing 12. The guide drive assembly 7 includes a guide sleeve 14 slidably connected to one end of the housing 12, an abutment plate 27 fixedly installed at the outward end of the guide sleeve 14, and a return spring 15 installed between the guide sleeve 14 and the first mounting plate 13. Figure 3 and Figure 4 The outer wall of the guide sleeve 14 is provided with a limit groove 16, and a plurality of limit grooves 16 are provided along the circumference of the guide sleeve 14. A plurality of limit blocks 17 are fixedly provided on the inner wall of the housing 12, and each limit block 17 corresponds to a limit groove 16. The limit block 17 is slidably connected in the limit groove 16. Thus, the guide sleeve 14 is stably slidably connected to the housing 12. Figure 2 and Figure 3 The upper end of the guide sleeve 14 is closed, and the return spring 15 abuts against the upper end of the guide sleeve 14 and the first mounting plate 13 .

[0063] Reference Figure 3 and Figure 5 The side wall of the guide sleeve 14 is provided with a guide groove 18 along its axial direction, and two guide grooves 18 are provided, and one rotating shaft 19 corresponds to one guide groove 18. The rotating shaft 19 passes through the guide groove 18 and is slidably connected to the guide groove 18. A gear 20 is fixedly sleeved on the rotating shaft 19. A rack 21 is fixedly installed on the side wall of the guide groove 18 along its length direction. The rack 21 is located in the middle of the guide groove 18 and is shorter than the guide groove 18. The gear 20 is meshed with the rack 21.

[0064] Reference Figure 2 and Figure 3 In the initial state, the return spring 15 is in a natural state, the abutment plate 27 is located outside the housing 12, the red seal assembly 6 is located at the upper end of the guide sleeve 14, and the red seal body 11 is in a state of facing away from the abutment plate 27. At this time, since the red seal body 11 is facing away from the abutment plate 27, that is, facing the inside of the housing 12, outsiders cannot see the contents of the red seal book, which is safer.

[0065] When stamping is needed, the abutment plate 27 is abutted against the plane that needs to be stamped, and the housing 12 is pushed downward to make the housing 12 slide relative to the guide sleeve 14. At this time, the rotating shaft 19 slides in the guide groove 18, and due to the cooperation of the gear 20 and the rack 21, the red seal assembly 6 is rotated relative to the housing 12 until the red seal body 11 rotates to the state facing the plane that needs to be stamped. The rotating shaft 19 continues to slide in the guide groove 18 until the red seal body 11 abuts against the plane that needs to be stamped, and the stamping is completed. When the housing 12 slides relative to the guide sleeve 14, the reset spring 15 is compressed. After the stamping is completed, the force applied to the housing 12 is removed, and the guide sleeve 14 slides relative to the housing 12 under the action of the reset spring 15 and resets to the initial state. In this process, the rotating shaft 19 also slides in the guide groove 18 in the opposite direction and rotates in the opposite direction, and the red seal assembly 6 is rotated to the state facing the inside of the housing 12 to ensure safety.

[0066] Reference Figure 6In order to facilitate the replacement of different seals, the inner mounting seat 10 is detachably connected to the outer mounting seat 9. Specifically, the first receiving groove 8 is a circular groove, and the inner side wall of the first receiving groove 8 is provided with a first card slot 22 along its circumference, and two first card slots 22 are provided along the circumference of the first receiving groove 8. A second card slot 23 connecting to the open end of the first receiving groove 8 is provided on the side wall of the first card slot 22 along the axial direction of the first receiving groove 8. A third card slot 24 is provided on the side wall of the first card slot 22 away from the second card slot 23 along the axial direction of the first receiving groove 8. The third card slot 24 and the second card slot 23 are respectively located at both ends of the first card slot 22. A plurality of card blocks 25 are provided on the outer wall of the inner mounting seat 10, and each card block 25 corresponds to a first card slot 22.

[0067] When a different seal needs to be replaced, the inner mounting seat 10 can be pulled up relative to the outer mounting seat 9, and then the inner mounting seat 10 can be rotated until the block 25 slides to the end of the first slot 22 corresponding to the second slot 23, and finally the inner mounting seat 10 can be pulled outward to complete the removal of the inner mounting seat 10. Then align the block 25 of the inner mounting seat 10 with the new red seal installed with the second slot 23, and then the block 25 slides through the second slot 23 until it enters the first slot 22. The inner mounting seat 10 is rotated relative to the outer mounting seat 9, so that the block 25 slides in the first slot 22 to the top of the third slot 24, and is inserted into the third slot 24. In this way, the inner mounting seat 10 is stably installed in the outer mounting seat 9, and the replacement is completed.

[0068] Reference Figure 1 In order to protect the guide sleeve 14, a protective cover 26 is detachably connected to one end of the housing 12. The protective cover 26 is sleeved outside the guide sleeve 14 and the abutment plate 27 and covers the guide sleeve 14 and the abutment plate 27. Specifically, a clamping protrusion 28 is provided on the inner wall of the protective cover 26, and a clamping groove 29 is provided on the outer wall of the housing 12. When the protective cover 26 is sleeved outside the guide sleeve 14, the clamping protrusion 28 is clamped in the clamping groove 29.

[0069] Reference Figure 2 and Figure 3 The ink pad module 2 includes an ink pad box 30 with a second receiving groove and ink pad filled in the second receiving groove. The inner wall of the guide sleeve 14 is provided with a support plate 31 along its circumference. The ink pad box 30 is located between the closed end of the guide sleeve 14 and the support plate 31 and abuts against the support plate 31. The ink pad faces the stamping module 1. Figure 7 In order to facilitate the replacement of the ink pad box 30, a first through slot 32 is provided on one side of the guide sleeve 14 for the ink pad box 30 to slide out of the guide sleeve 14 in a horizontal direction. A second through slot 33 is provided on one side of the housing 12 for the ink pad to slide out of the housing 12 in a horizontal direction, and the second through slot 33 is connected to the first through slot 32. Figure 1 and Figure 3The other end of the guide sleeve 14 is provided with a first through hole 34 for a needle to pass through the guide sleeve 14 to push the ink pad box 30 to slide toward the first through groove 32. The housing 12 is provided with a second through hole 35 connected to the first through hole 34. When the ink pad box 30 needs to be replaced, the needle can be passed through the first through hole 34 and the second through hole 35 to push the ink pad box 30 outward, so that the ink pad box 30 is completely disassembled. Then a new ink pad box 30 can be installed.

[0070] Reference Figure 7 In order to prevent the ink box 30 from falling out of the housing 12 from the first through slot 32 and the second through slot 33, a cover 36 is embedded in the second through slot 33. The cover 36 seals the second through slot 33. The specific structure is the same as the structure of the battery box of the TV remote control panel.

[0071] Reference Figure 2 and Figure 8 , a second mounting plate 37 is fixedly disposed at the upper end of the housing 12. The locking module 4 includes a first guide rod 38 arranged axially along the housing 12 and fixedly connected to the closed end of the guide sleeve 14, a swing rod 39 rotatably connected to the upper end of the second mounting plate 37, and a driving motor 40 for driving the swing rod 39 to rotate. The second mounting plate 37 is provided with guide holes 41 for the two first guide rods 38 to pass through. The two guide holes 41 are distributed at both ends of the swing rod 39. The swing rod 39 can rotate relative to the second mounting plate 37 to close the two guide holes 41, and can also rotate to a state where it does not overlap with the two guide holes 41 at all.

[0072] When the locking module 4 is in the state of locking the stamping module 1, the swing rod 39 closes the two guide holes 41, so that the first guide rod 38 cannot pass through the guide holes 41. As a result, the guide sleeve 14 cannot slide relative to the housing 12, so that the stamping module 1 is locked and cannot be stamped. When a signal requiring stamping is received, the first driving member drives the swing rod 39 to rotate, thereby opening the two guide holes 41. At this time, the first guide rod 38 can pass through the guide holes 41, unlocking the stamping module 1, so that it can perform the stamping function.

[0073] In order to ensure that the rocker arm 39 does not completely cover the guide hole 41 when the locking module 4 is in the unlocked state, the rocker arm 39 completely closes the guide hole 41 when the locking module 4 is in the locked state. Two contact switches 42 are fixedly mounted on the second mounting plate 37. When a signal requiring stamping is received, the first driving member drives the rocker arm 39 to rotate until it abuts against one of the contact switches 42, the first driving member stops driving, and the rocker arm 39 completely leaves the guide hole 41; when stamping is completed, the first driving member drives the rocker arm 39 to rotate in the opposite direction until it abuts against the other contact switch 42, the first driving member stops driving, and the rocker arm 39 completely closes the guide hole 41. This ensures that the locking module 4 can stably switch between the two states of locking the stamping module 1 and unlocking the stamping module 1.

[0074] Reference Figure 8 The counting module 3 includes a second guide rod 43 axially arranged along the housing 12 and fixedly connected to the closed end of the guide sleeve 14 and two photoelectric sensors 44 mounted on the second mounting plate 37. The second guide rod 43 passes through the second mounting plate 37 and is slidably connected to the second mounting plate 37. One second guide rod 43 corresponds to one photoelectric sensor 44. When the reset spring 15 is in a natural state, one of the second guide rods 43 blocks its corresponding photoelectric sensor 44; when the stamping module 1 is in a stamping state and abuts against the plane to be stamped, the second guide rod 43 that originally blocked the photoelectric sensor 44 leaves the photoelectric sensor 44, and the other second guide rod 43 covers its corresponding photoelectric sensor 44, so that the blocking of the two photoelectric sensors 44 is used as a signal to count the times and complete one count. If the number of counts reaches a preset number, the control module 5 drives the locking module 4 to lock the stamping module 1, thereby ensuring that the stamp can only be stamped with a preset number of stamping times to ensure safety.

[0075] For the convenience of use, the seal also includes a display module 45. The display module 45 is used to display the number of times the seal is used and the countdown of the seal use.

[0076] In order to increase the security of the smart seal, the use of the above-mentioned seal is as follows:

[0077] The working mode of the seal is divided into debugging mode and working mode. When the seal is in working mode, the operation includes the following steps:

[0078] Step S1: power-on inspection, turn on the power button of the seal, and the controller determines whether the movable parts are reset according to the state of the photoelectric sensor 44. If the seal has been reset normally, the seal will be prompted to enter the standby mode, and the voice module will prompt the seal to enter the standby mode. If the seal has not been reset normally, the seal will send an alarm signal and the seal cannot be opened;

[0079] The state of the photoelectric sensor 44 is related to the relative position of the photoelectric sensor 44 and the second guide rod 43. When the photoelectric sensor 44 senses the second guide rod 43 and when it does not sense the second guide rod 43, the signal transmitted by the photoelectric sensor 44 to the control module 5 is opposite.

[0080] Step S2: Application for seal use. When a seal user needs to use a seal, the seal user fills in the application information for this application on the operation platform, including the number of times the seal is used, the place of use, the time of use, the purpose of use, the number of times the seal is used, and the seal user;

[0081] Step S3: Seal approval. After the seal user applies, the management platform automatically selects information, including the number of times the seal is used, the place of use, the time of use, the purpose of use, the number of times the seal is used, and the person who uses the seal. The approver approves the seal application information through the management platform and gives an approval opinion. If the applicant is not allowed to use the seal, the process ends. If the applicant agrees, the relevant approval instruction is sent to the receiving mobile phone of the seal applicant; at the same time, the applicant's mobile terminal used to apply for the approval obtains the key, opens Bluetooth to connect with the seal through the mobile terminal, and uses the key to open the seal; the key of each smart seal is different after leaving the factory;

[0082] Step S4: Seal positioning function and seal unlocking. When the execution operation platform of the seal applicant receives the seal approval instruction, the seal control module 5 starts the positioning module to locate the current location of the seal in real time. Only when the positioning location is consistent with the application location, the seal will start the identity recognition function;

[0083] Step S5: timing function and counting function. The real-time monitoring system of the seal includes a timing function and a counting module. The timing function is realized by the internal timer of the controller. When one of the seal usage time and the seal usage number detected by the counting module reaches the approved usage time and number of usage, the seal will automatically stop working. The control module 5 sends a signal to the locking module 4, so that the locking module 4 controls the stamping module 1 to be in a locked state, and the voice module is turned on and broadcasts "the seal is closed". After the seal's authority is used up for several minutes, if no new instruction is received from the management platform again, the controller will turn off the power supply of the seal through the power supply module;

[0084] Step S6: Take photos of the document before and after stamping through the mobile terminal, and compare and judge the photos before and after stamping at the shooting stage after stamping. Specifically, compare the number of photos before and after taken, perform text recognition and comparison on the photos before and after, and use big data learning (stroke similarity, radical similarity, etc.) to judge the similarity of different points in the photos before and after. If the difference is large, send a warning report to the approval terminal and the mobile terminal at the same time.

[0085] Step S7: monitor the power of the battery module, and when the power is less than 10%, give a prompt and make the locking module 4 in a state of locking the stamping module 1 through the control module 5 .

[0086] The operation of the stamp when it is in debug mode includes the following steps:

[0087] In the above-mentioned method of using the seal, when the administrator sets the seal in the debugging mode, the motor rotates the swing rod 39 to a position not on the motion path of the first guide rod 38, applies pressure to the housing 12, and the reset spring 15 is compressed, driving the stamping module 1 to rotate the red seal body 11 to expose the seal, thus completing the stamping action. Then the second driving member drives the stop rod to rotate and snap into the stop groove of the first guide rod 38, so that the reset spring 15 cannot be reset. Thus, the red seal body 11 remains exposed. At this time, the red seal body 11 can be unscrewed and replaced with a new red seal.

[0088] Embodiment 2:

[0089] The difference between the second embodiment and the first embodiment is that the force exchange components are different. Fig. 9 and Fig.11 The force exchange assembly includes a guide groove 18 which is opened on the side wall of the guide sleeve 14 along the axial direction of the guide sleeve 14. Fig.10 and Fig.11 There are two guide grooves 18, and one rotating shaft 19 corresponds to one guide groove 18, and the rotating shaft 19 passes through the guide groove 18 and is slidably connected to the guide groove 18. The guide groove 18 includes a guide portion 46 and a reversing portion 47, the reversing portion 47 is arranged in an arc shape, and the guide portion 46 is arranged along the axial direction of the guide sleeve 14. Two guide portions 46 are provided and are respectively connected to both ends of the reversing portion 47.

[0090] In the initial state, the return spring 15 is in a natural state, the abutment plate 27 is located outside the housing 12, the red seal assembly 6 is located at the upper end of the guide sleeve 14, and the red seal body 11 is in a state of facing away from the abutment plate 27. At this time, since the red seal body 11 is in a state of facing away from the abutment plate 27, that is, facing the inside of the housing 12, outsiders cannot see the contents of the red seal book, which is safer.

[0091] When stamping is required, the contact plate 27 is abutted against the plane to be stamped, and the housing 12 is pushed downward to make the housing 12 slide relative to the guide sleeve 14. At this time, the rotating shaft 19 slides in the guide groove 18. When the rotating shaft 19 moves to the reversing portion 47, the rotating shaft 19 rotates under the action of the friction force of the side wall of the reversing portion 47, so that the red seal component 6 rotates relative to the housing 12 until the red seal body 11 rotates to the state facing the plane to be stamped. The rotating shaft 19 continues to slide in the guide groove 18 until the red seal body 11 abuts against the plane to be stamped, and the stamping is completed. When the housing 12 slides relative to the guide sleeve 14, the reset spring 15 is compressed. After the stamping is completed, the force applied to the housing 12 is removed, and the guide sleeve 14 slides relative to the housing 12 under the action of the reset spring 15 and resets to the initial state. During this process, the rotating shaft 19 also slides in the guide groove 18 in the opposite direction and rotates in the opposite direction, so that the red seal assembly 6 rotates to a state facing the inside of the housing 12 to ensure safety.

[0092] Embodiment three:

[0093] The difference between the third embodiment and the first embodiment is that the locking module 4 is different. Fig.12 and Fig.13 The locking module 4 includes a first guide rod 38 arranged along the axial direction of the housing 12 and fixedly connected to the closed end of the guide sleeve 14, a limit rod 48 slidably connected to the upper end of the second mounting plate 37, and a first driving member for driving the limit rod 48 to slide relative to the second mounting plate 37. The first driving member includes a force transmission rack 49 arranged on the limit rod 48, a force transmission gear 50 meshed with the force transmission rack 49, and a driving motor 40 for driving the force transmission gear 50 to rotate, and the driving motor 40 is installed on the second mounting plate 37. The first guide rod 38 passes through the second mounting plate 37 and is slidably connected to the second mounting plate 37 along the axial direction of the housing 12. The first guide rod 38 is provided with a limit hole 51 for the limit rod 48 to pass through.

[0094] Reference Fig.12 and Fig.13 Specifically, the limiting rod 48 includes a first rod 52 axially arranged along the limiting hole 51, a second rod 53 perpendicular to the first rod 52 and fixedly connected to the first rod 52, and a latch 54 installed on the second rod 53. The force transmission rack 49 is fixedly connected to the end of the first rod 52 away from the second rod 53 and parallel to the first rod 52. The latch 54 is fixedly connected to the side of the second rod 53 away from the first rod 52.

[0095] When the seal needs to be locked, the first driving member drives the limiting rod 48 to slide relative to the second mounting plate 37 until the latch 54 passes through the limiting hole 51. The first guide rod 38 cannot move relative to the second mounting plate 37, so that the stamping module 1 is locked and cannot be stamped. Therefore, when a signal that stamping is required is received, the first driving member drives the limiting rod 48 to slide, so that the latch 54 leaves the limiting hole 51. At this time, the first guide rod 38 can slide relative to the second mounting plate 37, unlocking the stamping module 1, so that it can perform the stamping function.

[0096] In order to ensure that the locking module 4 is in the unlocked state, the limit rod 48 moves into place. Two contact switches 42 are fixedly mounted on the second mounting plate 37, and the two contact switches 42 are respectively located on both sides of the second rod 53. When the limit rod 48 receives a signal that requires stamping, the first driving member drives the limit rod 48 to slide until the second rod 53 abuts against one of the contact switches 42, the first driving member stops driving, and the rocker 39 completely leaves the limit hole 51; when stamping is completed, the first driving member drives the limit rod 48 to slide in the opposite direction until the second rod 53 abuts against another contact switch 42, the first driving member stops driving, and the latch 54 completely leaves the limit hole 51. This ensures that the locking module 4 can stably switch between the two states of locking the stamping module 1 and unlocking the stamping module 1.

[0097] The above is only the preferred implementation of the present application. The protection scope of the present application is not limited to the above embodiments. All technical solutions under the concept of the present application belong to the protection scope of the present application. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present application should also be regarded as the protection scope of the present application.
