Description

Technical Field

[0001] The present application relates to the field of smart office, and in particular to a smart seal. Background Art

[0002] Seals, also known as stamps, are stationery used to print on documents to indicate identification or signature. There are many types of seals commonly used, generally including red rubber seals, photosensitive seals, ink-returning seals, horn seals and copper seals, etc. Due to the design requirements of the seal itself, the overall structure is relatively small and easy to operate.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the use of traditional seals is difficult to reduce the occurrence of crimes caused by other people using seals (stealing or stealing) without supervision. Although it is possible to discover it afterwards, it is too late, causing irreparable economic losses to the country, enterprises and individuals. Summary of the invention

[0004] In order to facilitate the supervision of the use of seals and reduce the situation where other people can use seals at will, the present application provides a smart seal.

[0005] The present application provides a smart seal, which adopts the following technical solution:

[0006] A smart seal comprises an outer shell, an inner shell is vertically arranged below the outer shell, the outer shell and the inner shell are slidably connected, a seal is slidably connected inside the inner shell, a protective cover is horizontally arranged on the inner shell below the seal, a locking structure is arranged on the position of the inner shell relative to the protective cover, and the opening of the protective cover is restricted by the locking structure.

[0007] By adopting the above technical solution, the outer shell is pressed down so that the outer shell slides relatively on the outside of the inner shell, and the movement of the outer shell drives the seal to move downward. By opening the protective cover, the seal is moved out from the inside of the protective cover, and then the bottom end of the seal extends from the bottom end of the inner shell, thereby performing the stamping operation. When the use of the seal is not allowed, the protective cover is locked by the locking structure to reduce the seal from extending from the inside of the protective cover, thereby facilitating the supervision of the use of the seal and reducing the situation where other people can use the seal at will.

[0008] Optionally, a guide groove is provided in the inner shell relative to the protective cover, the guide groove is an arc-shaped structure, and the arc center of the guide groove is located above the protective cover, a pull rope is fixedly connected to the outer shell, and a rotating wheel is rotatably connected to the top of the inner shell, and the other end of the pull rope is fixedly connected to one end of the protective cover close to the inner shell.

[0009] By adopting the above technical solution, when the outer shell moves downward, the end of the pull rope close to the outer shell is driven to move downward, and then the end of the pull rope away from the outer shell is driven to move upward, thereby driving the end of the protective cover close to the inner shell to move upward, and the end of the protective cover away from the side wall of the inner shell moves along the direction of the guide groove to open the protective cover.

[0010] Optionally, a top plate is horizontally arranged inside the outer shell, and the top plate is fixedly connected to the outer shell, and a limit plate is fixedly connected to the side wall of the inner shell, and the bottom wall of the outer shell is opposite to the limit plate. When the outer shell moves downward, the bottom wall of the outer shell can abut against the limit plate, and a pressure plate is horizontally arranged above the seal, and a first elastic member is vertically arranged between the pressure plate and the seal. When the bottom end of the outer shell abuts against the top wall of the limit plate, the bottom wall of the seal extends from the bottom wall of the inner shell, and at this time, when the seal compresses the first elastic member, the bottom wall of the seal can be flush with the bottom wall of the inner shell.

[0011] By adopting the above technical solution, when the outer shell moves downward, the outer shell drives the top plate to move downward, and then after the top plate abuts against the pressure plate, the top plate drives the pressure plate to move downward, thereby driving the seal to move downward, and when the bottom end of the outer shell abuts against the limit plate, the outer shell is located at the lowest end, and when the outer shell is located at the lowest end, the bottom end of the seal is lower than the bottom end of the inner shell, and when the seal is stamped, the bottom end of the seal is flush with the bottom end of the inner shell, thereby compressing the first elastic member, and the seal is pressed to the position where it needs to be stamped through the rebound force of the first elastic member.

[0012] Optionally, a second elastic member is vertically arranged inside the outer shell, a support plate is horizontally arranged on the inner shell relative to the second elastic member, the support plate is fixedly connected to the inner shell, and the inner shell is fixedly connected to the second elastic member.

[0013] By adopting the above technical solution, when the shell moves downward, the shell compresses the second elastic member, so that when the stamping is completed, the second elastic member pushes the shell to move upward to restore to the initial state.

[0014] Optionally, the seal includes a handle portion and a working portion horizontally arranged at the bottom end of the handle portion, a slider is clamped on the side wall of the handle portion, the bottom end of the slider is abutted against the working portion, the slider is slidably connected to the inner shell, and a horizontal plate is horizontally arranged on the inner side wall of the inner shell relative to the top of the slider, a third elastic member is vertically arranged between the horizontal plate and the slider, one end of the third elastic member is fixedly connected to the horizontal plate, and the other end of the third elastic member is fixedly connected to the slider.

[0015] By adopting the above technical solution, the slider is clamped between the handle and the working part of the seal, so that the shell drives the slider to move downward, thereby stretching the third elastic member. When the stamp is completed, the slider is pulled by the third elastic member to return to the initial state.

[0016] Optionally, the locking structure includes a locking block located below the protective cover, the inner shell is provided with a locking groove at a position relative to the locking block, the locking block is located inside the locking groove and is relatively slidably connected, a locking rod is vertically slidably connected inside the locking groove, a first inclined wall is provided at a position relative to the locking rod and the locking block, the first inclined wall is gradually inclined toward a side close to the locking block along a height direction from top to bottom, the locking block is provided with a second inclined wall at a position relative to the first inclined wall, the inclination direction of the second inclined wall is the same as the inclination direction of the first inclined wall, and the first inclined wall and the second inclined wall abut and slide, a driving member for driving the locking rod to move up and down is provided below the locking rod, the driving member is connected to a signal of an external control system, when the external control system sends a signal, the driving member drives the locking rod to move downward, a fourth elastic member is horizontally provided on a side of the locking block close to the locking rod, one end of the fourth elastic member is fixedly connected to the locking block, and the other end of the fourth elastic member is fixedly connected to the inner shell.

[0017] By adopting the above technical solution, when the driving member receives a signal from the outside world, the driving member drives the locking rod to move downward, and then the locking rod is relatively disengaged from the locking block, and the fourth elastic member pulls the locking block to retract into the interior of the locking groove, so that the protective cover can be flipped, and when locking is required, the driving member drives the locking rod to move upward, so that the first inclined wall of the locking rod and the second inclined wall of the locking block are relatively abutted, and then the locking rod pushes the locking block to move toward the end away from the locking rod, thereby limiting the flipping of the protective cover.

[0018] Optionally, a pressure sensor is fixedly connected to the position of the inner shell relative to the fourth elastic member, and the pressure sensor is fixedly connected to the fourth elastic member. The pressure sensor can detect the pressure generated by the fourth elastic member.

[0019] By adopting the above technical solution, when someone pushes the locking block without permission, the locking block compresses the fourth elastic member, and the fourth elastic member generates abnormal pressure. When the pressure sensor detects the abnormal pressure, an alarm is generated.

[0020] Optionally, a side of the protective cover close to the seal is fixedly connected with an ink layer, and the ink layer abuts against the lower surface of the seal.

[0021] By adopting the above technical solution, when the protective cover is in a horizontal state, the ink layer and the seal are relatively abutted, so that the seal can be stamped clearly and conveniently.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By pressing down the outer shell, the outer shell slides relatively on the outside of the inner shell, and the movement of the outer shell drives the seal to move downward. By opening the protective cover, the seal moves out from the inside of the protective cover, and then the bottom end of the seal extends from the bottom end of the inner shell, so as to perform the stamping operation. When the use of the seal is not allowed, the protective cover is locked by the locking structure to reduce the seal from extending from the inside of the protective cover, which is convenient for supervision of the use of the seal and reduces the situation where other people can use the seal at will.

[0024] 2. When the outer shell moves downward, the outer shell drives the top plate to move downward, and then after the top plate abuts against the pressure plate, the top plate drives the pressure plate to move downward, thereby driving the seal to move downward. When the bottom end of the outer shell abuts against the limit plate, the outer shell is located at the lowest end, and when the outer shell is at the lowest end, the bottom end of the seal is lower than the bottom end of the inner shell, and when the seal is stamped, the bottom end of the seal is flush with the bottom end of the inner shell, thereby compressing the first elastic member, and the seal is pressed to the position where it needs to be stamped through the rebound force of the first elastic member.

[0025] 3. When the driving member receives a signal from the outside world, the driving member drives the locking rod to move downward, and then the locking rod is relatively disengaged from the locking block, and the fourth elastic member pulls the locking block to retract into the locking groove, so that the protective cover can be flipped, and when locking is required, the driving member drives the locking rod to move upward, so that the first inclined wall of the locking rod and the second inclined wall of the locking block are relatively abutted, and then the locking rod pushes the locking block to move toward the end away from the locking rod, thereby limiting the flipping of the protective cover.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a smart seal. Figure 1 , Figure 2 A smart seal includes an outer shell 1, an inner shell 2 is vertically arranged below the outer shell 1, the outer shell 1 is sleeved on the outer side of the inner shell 2 and is relatively slidably connected, a seal is vertically arranged inside the inner shell 2, and a driving structure 4 for driving the seal to move downward is arranged inside the outer shell 1. A protective cover 5 is horizontally arranged below the seal, and an opening structure for driving the protective cover 5 to flip open so as to leak out the seal is arranged inside the inner shell 2. Figure 3 A locking structure 7 for locking the protective cover 5 is also provided on the side wall of the inner shell 2. The locking structure 7 reduces the risk of unauthorized personnel opening the protective cover 5 and using the seal.

[0033] Reference Figure 2 , Figure 3 The seal includes a handle portion located at the top and a working portion 32 located below the handle portion. The handle portion and the working portion 32 are fixedly connected, and the handle portion includes a horizontally arranged first sub-portion 311 and a vertically arranged second sub-portion 312. The first sub-portion 311 and the second sub-portion 312 are fixedly connected. A slider 33 is horizontally arranged between the first sub-portion 311 and the working portion 32. The slider 33 abuts against and is relatively slidably connected to the inner shell 2. A slide groove 21 is vertically opened on the side wall of the inner shell 2 relative to the position of the slider 33. A sliding block 331 is fixedly connected to the slider 33 relative to the position of the slide groove 21. The sliding block 331 is located inside the slide groove 21 and is relatively slidably connected.

[0034] The driving structure 4 includes a pressing plate 34 horizontally arranged above the first subdivision 311, a first spring 341 vertically arranged between the pressing plate 34 and the first subdivision 311, the top end of the first spring 341 is fixedly connected to the pressing plate 34, and the bottom end of the first spring 341 is fixedly connected to the first subdivision 311. A top plate 11 is horizontally arranged inside the housing 1 relative to the top of the first subdivision 311, and the top plate 11 is fixedly connected to the housing 1. When the housing 1 moves downward, the top plate 11 can abut against the pressing plate 34, and the top plate 11 drives the pressing plate 34 to move downward, thereby driving the seal to move downward, so that the bottom end of the seal extends from the bottom wall of the inner housing 2.

[0035] The bottom end of the side wall of the inner shell 2 is fixedly connected to the limit plate 22, and the bottom end of the outer shell 1 is opposite to the limit plate 22. When the outer shell 1 moves downward, the bottom end of the outer shell 1 can abut against the limit plate 22, and the movement of the outer shell 1 is limited by the limit plate 22. When the outer shell 1 moves downward, when the outer shell 1 abuts against the limit plate 22, it is the lowest end of the movement of the outer shell 1, and when the outer shell 1 is at the lowest end, the lower surface of the seal extends from the bottom wall of the inner shell 2, and when the bottom wall of the seal is located on the paper for stamping, the lower surface of the seal retracts into the inner shell 2, compressing the first spring 341, so that the elastic force of the first spring 341 is applied to the seal, thereby facilitating the operation of the seal.

[0036] A second spring 12 is vertically arranged inside the outer shell 1, and a support plate is horizontally arranged on the inner shell 2 relative to the position of the second spring 12, and the top end of the second spring 12 is fixedly connected to the outer shell 1, and the bottom end of the second spring 12 is fixedly connected to the support plate. A horizontal plate 24 is horizontally arranged on the inner side wall of the inner shell 2 relative to the top of the slider 33, and the horizontal plate 24 is fixedly connected to the inner shell 2, and a third spring 241 is vertically arranged between the horizontal plate 24 and the slider 33, and the top end of the third spring 241 is fixedly connected to the horizontal plate 24, and the bottom end of the third spring 241 is fixedly connected to the slider 33. When the outer shell 1 moves downward, the top plate 11 drives the pressure plate 34 to move downward, and then the slider 33 is mobilized to move downward, and when the outer shell 1 moves to the bottom, the third spring 241 pulls the slider 33 to move upward, and the slider 33 drives the seal to move upward, so that the seal returns to its original position.

[0037] Reference Figure 3 , Figure 4 Two protective covers 5 are arranged opposite to each other, and the two protective covers 5 are arranged horizontally. One end of the protective cover 5 close to the side wall of the inner shell 2 is slidably connected to the inner shell 2, and can slide up and down along the inside of the inner shell 2. A guide groove 25 is opened on the side wall of the inner shell 2 relative to the end of the protective cover 5 away from the inner shell 2. The guide groove 25 is an arc structure, and the center of the arc is located above the protective cover 5. The protective cover 5 is fixedly connected with a guide block 51 relative to the guide groove 25. The guide block 51 is located inside the guide groove 25 and is relatively slidably connected.

[0038] When the protective cover 5 moves upward near the side of the inner shell 2, the guide block 51 is driven to slide relatively inside the guide groove 25, so that the protective cover 5 is turned over to a vertical state, and the seal is leaked out.

[0039] The opening structure includes a rotating wheel 61 rotatably connected to the top of the inner shell 2, and a pull rope 62 is fixedly connected to the inner bottom wall of the outer shell 1, and the pull rope 62 slides against the side wall of the rotating wheel 61, and the other end of the pull rope 62 is fixedly connected to the end of the protective cover 5 close to the side wall of the inner shell 2. When the outer shell 1 moves downward, the end of the pull rope 62 close to the outer shell 1 is driven to move downward, and then the end of the pull rope 62 close to the inner shell 2 is driven to move upward, pulling the end of the protective cover 5 close to the inner shell 2 to move upward, thereby driving the protective cover 5 to flip.

[0040] The locking structure 7 includes a locking block 71 horizontally arranged inside the inner shell 2, the locking block 71 is located below the protective cover 5, and the upper surface of the locking block 71 abuts against the lower surface of the protective cover 5. The inner shell 2 is provided with a locking groove 26 at a position relative to the locking block 71, and the locking block 71 is located inside the locking groove 26 and is relatively slidably connected, a locking rod 72 is vertically arranged below the locking block 71, and the locking rod 72 is slidably connected to the inner shell 2, a first inclined wall 721 is provided on the side of the locking rod 72 opposite to the locking block 71, and the inclination direction of the first inclined wall 721 is gradually inclined toward the side close to the locking block 71 along the height direction from top to bottom, and a second inclined wall 711 is provided at the position of the locking block 71 opposite to the first inclined wall 721 of the locking rod 72, the surface of the second inclined wall 711 is inclined, and the inclination directions of the second inclined wall 711 and the first inclined wall 721 are the same, and the first inclined wall 721 and the second inclined wall 711 abut against each other and are relatively slidably connected.

[0041] A hydraulic cylinder 73 is vertically arranged on the inner wall of the inner shell 2 below the locking rod 72. The hydraulic rod of the hydraulic cylinder 73 is fixedly connected to the locking rod 72, and the locking rod 72 is driven to move up and down by the hydraulic cylinder 73. The hydraulic cylinder 73 is connected to the external control system signal, so that when the external signal is sent, the hydraulic rod of the hydraulic cylinder 73 is controlled to extend.

[0042] A fourth spring 74 is horizontally arranged on one side of the locking block 71 near the bottom of the locking groove 26, and a pressure sensor 75 is fixedly connected to the side wall of the inner shell 2 relative to the position of the fourth spring 74. One end of the fourth spring 74 is fixedly connected to the locking block 71, and the other end of the fourth spring 74 is fixedly connected to the pressure sensor 75.

[0043] When the hydraulic cylinder 73 drives the locking rod 72 to move downward, the fourth spring 74 pulls the locking block 71 back into the locking groove 26, thereby facilitating the flipping of the protective cover 5, and when the hydraulic cylinder 73 pushes the locking rod 72 to move upward, the first inclined wall 721 and the second inclined wall 711 cooperate to push the locking block 71 out of the locking groove 26, thereby limiting the position of the protective cover 5. When the outside world thinks that the locking block 71 is pushed by the operation, the pressure sensor 75 detects abnormal pressure and issues an alarm.

[0044] The upper surface of the protective cover 5 is also fixedly connected with an ink layer 523 . When the second spring 12 is in a free state, the lower surface of the seal abuts against the ink layer 523 .

[0045] The implementation principle of a smart seal in an embodiment of the present application is: by pressing the outer shell 1 downward, the outer shell 1 moves downward on the outside of the inner shell 2, and the outer shell 1 drives the pull rope 62 to move downward at one end close to the outer shell 1, and then drives the pull rope 62 to move upward at one end close to the inner shell 2, driving the guide block 51 to slide relatively inside the guide groove 25, and driving the protective cover 5 to open.

[0046] During the downward movement of the outer shell 1, the outer shell 1 drives the top plate 11 to move downward, and the top plate 11 abuts against the pressure plate 34. The top plate 11 pushes the pressure plate 34 to move downward, thereby pushing the seal to move downward, so that the lower surface of the seal is exposed from the lower surface of the inner shell 2, thereby facilitating the stamping operation through the seal.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
