Description

Technical Field

[0001] The utility model relates to the field of seal equipment, in particular to a seal equipment with an anti-rubbing function. Background Art

[0002] Seals have been widely used on various documents, agreements, vouchers, bills and other written materials. As long as a legally registered seal is stamped on a written material, it means that the legal holder of the seal has legally recognized and agreed to the content of the current document, agreement and other written materials. With the development from traditional seal equipment that manually applies pressure to seal to intelligent seal equipment that applies pressure to seal, the structure of seal equipment is constantly changing.

[0003] Existing smart seal devices usually include a seal body, a seal shell and a driving mechanism. The seal shell has a seal outlet, and the seal body and the driving mechanism are located on the inner side of the seal shell. When stamping is required, manual pressing force is applied to the driving mechanism, and the driving mechanism pushes the seal body to the outer side of the seal outlet of the seal shell, so that the stamping surface of the pushed seal body is pressed against the surface of the object to be stamped, completing the stamping operation. When stamping is not required, the manual pressing force applied to the driving mechanism is released, and the driving mechanism brings the seal body located outside the seal outlet back to the inner side of the seal shell.

[0004] However, existing smart seal devices have some problems: after the seal body is retracted into the inner side of the seal shell, if someone presses the page of the material to be stamped against the seal surface of the retracted seal body for the purpose of rubbing and stamping, there will be a risk of the seal body being rubbed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a seal device with anti-rubbing function in view of the above-mentioned prior art. The seal device drives the seal carrier carrying the seal body to deviate by adding an anti-rubbing mechanism, so that the seal body deviates accordingly and an invalid seal pattern is stamped.

[0016] As a further improvement, in the seal device with anti-rubbing function, the lower end portion of the driving bracket has a notch for the second anti-rubbing structure on the seal carrier to move into.

[0017] As another implementation method of the first anti-rubbing structure and the second anti-rubbing structure cooperating with each other, in the seal device with anti-rubbing function, the seal carrier is acted upon by an electromagnetic driving force to drive the seal surface of the seal body to deflect, and the electromagnetic driving force is a magnetic homopolar repulsion force or a motor torque. For example, the first anti-rubbing structure and the second anti-rubbing structure are both magnetic devices and generate homopolar repulsion forces on each other.

[0032] The second positioning contact is located at the lower end of the driving bracket and is configured to touch the positioning device during the movement of the driving bracket.

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] Embodiment 1

[0045] This embodiment provides a seal device with an anti-rubbing function. Figures 1 to 7As shown, the seal device with anti-rubbing function of this embodiment includes a shell assembly 2 provided with a seal body 1, the shell assembly 2 also has a cavity 200, a driving bracket 3, a seal carrier 4 and an anti-rubbing mechanism, the cavity 200 is formed with a seal outlet 20 for the seal body to enter and exit, and the cavity 200 is configured to store the seal body 1 recovered through the seal outlet 20; the driving bracket 3 is located in the shell assembly 2, and the driving bracket 3 is configured to move back and forth from the inside of the cavity 200 toward the outside of the seal outlet 20 after being subjected to force; the seal carrier 4 is located in the shell assembly 2, the upper end of the seal carrier 4 is elastically connected to the lower end 31 of the driving bracket 3, and the end 31 can adopt a hanging plate structure, and the lower end of the seal carrier 4 is mounted with the seal body 1. Among them, the anti-rubbing mechanism here is located in the shell assembly 2 and is configured to make the seal carrier 4 offset relative to the normal position of the seal carrier 4 when the seal body 1 is subjected to rubbing pressure, so as to drive the seal body 1 to shift with the seal carrier 4; wherein, the normal position of the seal carrier is the position of the seal carrier in the shell assembly corresponding to when the seal body is not subjected to rubbing pressure and is retracted into the cavity.

[0046] As the structural form of the housing assembly in this embodiment, the housing assembly 2 here includes a first housing 21 and a second housing 22 that are assembled and matched with each other, and the first housing 21 is formed with a first cavity 210; the lower end of the second housing 22 is formed with the above-mentioned cavity 200, and the cavity 200 cooperates with the first cavity 210 of the first housing 21 to form a receiving cavity. Among them, the second housing 22 is formed with a through hole 220 for the driving bracket 3 to move back and forth in the up and down directions.

[0047] According to actual needs, the first shell 21 and the second shell 22 of this embodiment can be assembled together in a detachable manner, or can also adopt an integrated structural design.

[0048] See also Figures 3 to 6 As shown, the anti-rubbing mechanism of this embodiment includes a first anti-rubbing structure 51 and a second anti-rubbing structure 52, the first anti-rubbing structure 51 is located in the housing assembly 2, specifically, the first anti-rubbing structure 51 is located on the inner side of the second housing 22, the second anti-rubbing structure 52 is located on the seal carrier 4 and cooperates with the first anti-rubbing structure 51 to cause the seal carrier 4 to deflect when the seal body 1 is subjected to rubbing pressure, and the deflection here is set to dislocation or deflection as needed. Preferably, the first anti-rubbing structure 51 and the second anti-rubbing structure here touch and cooperate with each other to produce dislocation.

[0049] As a way to realize the mutual contact and cooperation between the first anti-rubbing structure 51 and the second anti-rubbing structure, in this embodiment, the first anti-rubbing structure 51 has a first protrusion structure 511, and the second anti-rubbing structure 52 has a second protrusion structure 521, and the second protrusion structure 521 contacts and cooperates with the first protrusion structure 511.

[0050] In order to ensure that the seal body can be smoothly and normally retracted into the cavity of the shell assembly when not being rubbed, and the first anti-rubbing structure and the second anti-rubbing structure will not touch each other, so as to avoid the seal body from shifting with the seal carrier, in this embodiment, the lower end 31 of the driving bracket 3 has a notch 310 for the second anti-rubbing structure 52 on the seal carrier 4 to move into. In this way, when the driving bracket drives the seal carrier to retract the seal body, the second anti-rubbing structure 52 on the seal carrier 4 will move into the notch 310 of the lower end 31 of the driving bracket. As long as the seal body in the retracted state is not subjected to pressure, the seal carrier 4 will not move toward the lower end 31 of the driving bracket 3 by compressing the elastic member 34, and the second anti-rubbing structure 52 on the seal carrier 4 will not touch the first anti-rubbing structure 51 on the inner side of the second shell 22, thereby ensuring that the seal body retracted into the shell assembly will not be misplaced when it is not subjected to pressure applied by rubbing.

[0051] In addition, according to actual needs, the driving bracket 3 in this embodiment is designed as an L-shape as a whole, the lower end 31 of the driving bracket 3 is a horizontally arranged disc, and the upper end 32 of the driving bracket 3 is vertical. The upper end 32 of the driving bracket 3 is located in the above-mentioned accommodating cavity, and the seal body 1, the seal carrier 4 and the lower end 31 of the driving bracket 3 are all located in the cavity 200 at the lower end of the second shell 22.

[0052] In order to ensure that the seal device can automatically extend and retract the seal body, in this embodiment, the shell assembly 2 has a driving device 6, a positioning device 7 and a seal surface pressure sensing device 8. The driving device 6 is located in the above-mentioned accommodating cavity of the shell assembly 2 and is configured to drive the driving bracket 3 to move back and forth under the control of a preset controller; the positioning device 7 is located in the accommodating cavity of the shell assembly 2 and is configured to detect the movement displacement of the driving bracket 3 moving back and forth in the shell assembly, and send the detected movement displacement to the preset controller; the seal surface pressure sensing device 8 is arranged at the lower end portion 31 of the driving bracket 3, and the seal surface pressure sensing device 8 is configured to detect the pressure exerted on the seal surface 1a of the seal body 1 and send the detected pressure data to the preset controller.

[0053] For example, the seal surface pressing sensing device 8 is elastically connected to the seal carrier 4. In this way, when stamping, the seal carrier will touch the seal surface pressing sensing device 8 in an elastic manner, so that the seal surface pressing sensing device detects that the seal surface of the seal body has been subjected to pressure.

[0054] Specifically, see Figure 3As shown, the driving device 6 of this embodiment includes a motor 61 and a gear 62. The motor 61 has a front worm gear 611, and the motor 61 is fixed to the lower end 31 of the driving bracket 3 through a fastener 63; the gear 62 is rearward relative to the worm gear 611 and is arranged on the worm shaft of the worm gear 611; wherein the driving bracket 3 has a meshing structure 3a that meshes with the gear 62. The motor drives the worm gear to rotate, and then drives the driving bracket to move up and down through the gear, thereby achieving the purpose of controlling the driving bracket to move up and down, and then achieving the effect of the driving bracket driving the seal body to extend or retract from the seal outlet. In addition, by placing the worm gear in front and placing the motor and gear in the back, the situation of the motor gear reversing due to the reaction force of the driving bracket when stamping can be effectively prevented, and at the same time, the front worm gear can also effectively protect the gear to prevent the gear from being damaged by the reaction force when stamping.

[0055] In order to make the driving bracket more stably drive the seal carrier to move up and down, in this embodiment, the upper end 32 of the driving bracket 3 includes a first bracket 321 and a second bracket 322, the lower end of the first bracket 321 is connected to the seal carrier 4, and the second bracket 322 is fixed to the lower end 31 of the driving bracket 3, the first bracket 321 can pass through the through hole 220 of the second shell 22 and can move up and down relative to the second bracket 322 after being driven, the left side and the right side of the first bracket 321 are formed with the above-mentioned meshing structure 3a, and the first bracket 321 and the second bracket 322 form a limited space for the gear 62 to move. At the same time, the driving device 6 has a gear 62 that meshes with the meshing structure 3a on the left side of the first bracket 321 and another gear 62 that meshes with the meshing structure 3a on the right side of the first bracket 321. That is, when the gear 62 of the driving device rotates, the gear can drive the first bracket to move up and down relative to the second bracket to change the position of the seal carrier in the cavity of the shell assembly, thereby achieving the effect of retracting or extending the seal body.

[0056] In order to cooperate with the positioning device to detect the movement displacement of the drive bracket, see Figure 3As shown, the driving bracket 3 of this embodiment further includes a first positioning contact 331 and a second positioning contact 332. The first positioning contact 331 is located at the upper end 32 of the driving bracket 3, and the first positioning contact 331 is configured to touch the positioning device 7 during the movement of the driving bracket 3; the second positioning contact 332 is located at the lower end 31 of the driving bracket 3, and the second positioning contact 332 is configured to touch the positioning device 7 during the movement of the driving bracket 3. In this way, when the driving bracket moves from the inner side of the shell assembly toward the outer side of the chapter outlet, the second positioning contact 332 located at the lower end 31 of the driving bracket 3 is first detected by the positioning device 7, and the first positioning contact 331 located at the upper end 32 of the driving bracket 3 is finally detected by the positioning device 7. When the driving bracket moves in the reverse direction, the first positioning contact 331 is first detected by the positioning device 7, and the second positioning contact 332 is finally detected by the positioning device 7. In this way, the moving direction of the driving bracket can be known according to the order in which each positioning contact is detected. By setting the positions of the first positioning contact 331 and the second positioning contact 332 on the driving bracket 3 respectively, when the driving bracket moves in the positive direction from the inside of the shell assembly toward the outside of the chapter outlet, when the positioning device 7 finally detects the first positioning contact 331, the seal body mounted on the lower end of the driving bracket is just extended to the outside of the chapter outlet and can be stamped; when the driving bracket moves in the reverse direction, when the positioning device 7 finally detects the second positioning contact 332, the seal body mounted on the lower end of the driving bracket is just recovered from the outside of the chapter outlet to the inside of the shell assembly and cannot be stamped externally.

[0057] In order to satisfy the upside-down flipping of the shell assembly, so as to change the stamping surface of the seal body in the shell assembly, which originally faces the upper side of the shell assembly, to face the lower side of the shell assembly, and then complete the stamping action of the seal body on the material below the shell assembly, in the stamp device of this embodiment, a rotating arm 23 is provided on the side wall of the shell assembly 2 to cooperate with the shell assembly to achieve upside-down flipping. Specifically, the rotating arm 23 here is assembled by a first half rotating arm 231 located on the first shell 21 and a second half rotating arm 232 located on the second shell 22. Of course, in order to facilitate the wiring requirements of the functional components in the shell assembly, wiring holes can be formed on the rotating arms of the shell assembly 2.

[0058] As for the specific structure of the seal equipment, see Figure 8 and Fig. 9As shown, the seal device of this embodiment includes an upper shell 81, a lower shell 82 and a pressed structure 91 that bears manual pressing force. The upper shell 81 and the lower shell 82 are assembled together. The pressing structure 91 contacts the rotating arm 23 of the shell assembly 2 through the pressing rod 92 fastened thereto. The lower shell 82 has a rotating guide rail 93 that cooperates with the rotating arm 23 of the shell assembly 2 to realize the upside-down flipping of the shell assembly 2. The pressing structure 91, the shell assembly of this embodiment and the rotating guide rail 93 are all located in the space formed after the upper shell 81 and the lower shell 82 are assembled. The lower end of the lower shell 82 is formed with an outlet 94 for the seal body to be moved out of the shell assembly 2 and then moved out to the outside of the entire seal device.

[0059] The following combination Figures 1 to 9 , the anti-rubbing working principle of the seal device in this embodiment is explained:

[0060] When the seal body 1 of the seal device is not subjected to the pressure of rubbing and is retracted into the cavity 200 of the shell assembly by the driving mechanism, the second anti-rubbing structure 52 on the seal carrier 4 moves into the notch 310 of the lower end 31 of the driving bracket 3. In this state, the seal carrier will not elastically move toward the lower end of the driving bracket 3 due to the top contact pressure of the seal body, so that the second anti-rubbing structure 52 of the seal carrier will not touch the first anti-rubbing structure 51 in the second shell 22, so that the seal carrier will not be offset relative to the normal position of the above-mentioned seal carrier, and the seal surface of the seal body will not be offset along with the seal carrier.

[0061] When the seal body has been automatically retracted into the cavity 200 of the shell assembly by the driving mechanism, once the seal body is rubbed, the material to be stamped will inevitably contact the seal surface of the seal body and the material to be stamped will apply pressure to the seal body, and the seal body will also apply top contact pressure to the seal carrier. After receiving the top contact pressure of the seal body, the seal carrier moves toward the inner side of the cavity of the shell assembly and moves to the second anti-rubbing structure 52 of the seal carrier 4 to touch the first anti-rubbing structure 51 in the second shell 22, which causes the seal carrier to be offset relative to the normal position of the above-mentioned seal carrier, and the seal surface of the seal body is also offset with the seal carrier, so that the lines of the seal surface on the surface of the material to be stamped become thicker or blurred, and finally the seal pattern stamped on the material surface by the seal body after the offset is significantly different from the seal pattern stamped on the material surface when the seal body is not offset, thereby making the seal stamped by the seal device invalid when being rubbed.

[0062] Embodiment 2

[0063] The second embodiment provides another seal device with an anti-rubbing function. Specifically, the difference from the seal device in the first embodiment is that, in the seal device of the second embodiment, the first anti-rubbing structure 51 and the second anti-rubbing structure 52 are both magnetic devices and generate the same-sex repulsion force on each other. For example, the first anti-rubbing structure 51 and the second anti-rubbing structure 52 are both magnet components, and the surfaces of the first anti-rubbing structure 51 and the second anti-rubbing structure 52 that face each other are the same poles of the magnet components. Of course, according to actual needs, one of the first anti-rubbing structure 51 and the second anti-rubbing structure 52 can also be an electromagnet, and the other anti-rubbing structure can be a magnet component. In this way, once the second anti-rubbing structure 52 moves toward the direction close to the first anti-rubbing structure 51, due to the same polarity repulsion, the second anti-rubbing structure 52 and the first anti-rubbing structure 51 repel each other, causing the seal carrier 4 provided with the second anti-rubbing structure 52 to be offset relative to the normal position of the aforementioned seal carrier, which in turn causes the seal carrier to be offset relative to the normal position of the aforementioned seal carrier, and the seal surface of the seal body is also offset with the seal carrier, so that the lines of the seal surface on the surface of the material to be stamped become thicker or blurred, and finally the seal pattern stamped on the material surface after the offset by the seal body is significantly different from the seal pattern stamped on the material surface when the seal body is not offset, thereby making the seal stamped by the seal device invalid under the rubbing. That is to say, the seal carrier in the second embodiment is acted upon by an electromagnetic driving force to drive the seal surface of the seal body to deflect, and the electromagnetic driving force is a magnetic same polarity repulsion force or a motor torque.

[0064] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
