Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent seals, in particular to an intelligent seal with an anti-theft function. Background Art

[0002] Smart seal is an innovative tool that combines technologies such as the Internet of Things, the Internet, and big data, and is designed to achieve digital management and remote supervision of traditional physical seals. The physical seal is loaded into the smart seal device through a special seal fixture, and the seal administrator monitors and manages it in real time. The system realizes the separation of people and seals, supports remote application, approval, and real-time monitoring, and ensures the security and traceability of seal use.

[0003] In order to prevent smart seals from being stolen, existing smart seals are usually equipped with electronic monitoring functions, such as remote monitoring, real-time positioning, etc. The smart seals can be monitored in real time using monitoring equipment, but this method still has the following defects:

[0004] 1. Electronic monitoring methods may have blind spots or loopholes. For example, if the seal is removed in the monitoring blind spot, or the monitoring equipment is interfered with or turned off, the theft may not be discovered in time;

[0005] 2. When remote monitoring detects abnormal behavior, it may be necessary to go through a series of verification and confirmation processes before taking response measures. However, during this process, the seal may have been stolen or abused. The lack of a real-time response mechanism makes it impossible for the system to prevent theft in time. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a smart seal with an anti-theft function, which solves the problem that the anti-theft effect of the smart seal in the prior art is not good.

[0007] To achieve the above-mentioned purpose, according to the embodiment of the first aspect of the utility model, a smart seal with an anti-theft function is proposed, comprising a shell, a seal tube, a seal head, a body, a high-speed scanner and a lifting mechanism, wherein the seal tube is installed at the top of the shell, and the seal head is located in the seal tube, the high-speed scanner is installed at the top of the body, and the body and the seal tube are connected through the lifting mechanism, and fixed blocks for supporting the seal head are symmetrically arranged in the seal tube, and slide grooves are arranged in the two fixed blocks, and a movable block is arranged in the slide groove, and one end of the movable block is connected to the seal head. The side wall of the movable block is in contact with each other, and a first spring is installed between the other end of the movable block and the bottom of the slide slot. A groove corresponding to the fixed block is opened at the side wall of the seal cylinder, and a conductive ring is installed in the groove. One end of the movable block is connected to a pull rod passing through the conductive ring, and the end of the pull rod is connected to a conductive block. The two conductive blocks are electrically connected. A battery for powering the high-speed scanner is provided in the body, and the positive and negative poles of the battery are electrically connected to the two conductive rings through wires, respectively, and a fuse is connected in series between the positive pole of the battery and the corresponding conductive ring.

[0008] As a further technical solution of the utility model, the lifting mechanism includes a tube cover installed on the top of the seal tube, the tube cover covers the seal head, and a connecting plate is fixedly installed on the top of the tube cover. An electric push rod for controlling the lifting and lowering of the connecting plate is provided in the body.

[0009] As a further technical solution of the utility model, the seal cylinder comprises a cylinder body and a sleeve ring, and the sleeve ring is fixedly sleeved on the outer cylinder wall of the cylinder body near the top.

[0010] As a further technical solution of the utility model, the bottom end of the collar is connected to a second spring, the second spring is sleeved on the outside of the cylinder, and the second spring is installed inside the shell.

[0011] As a further technical solution of the utility model, a lead wire is wound around the outer wall of the seal tube near the top, and two ends of the lead wire are respectively connected to two conductive blocks.

[0012] As a further technical solution of the utility model, a buckle for limiting the position of the seal head is installed on the top of the seal tube.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, the seal tube is conveniently driven to rise and fall through the lifting mechanism, and the seal head is convenient for stamping. The stamped document is conveniently photographed and archived using the high-speed scanner. The stamped document will take effect only after successful archiving. When the seal head is disassembled, taken out and misused, the first spring will drive the movable block to reset, so that the pull rod drives the conductive block to fit the conductive ring, thereby forming a loop between the two conductive rings, causing the battery to overload and short-circuit, thereby disconnecting the fuse, ensuring that the battery cannot power the high-speed scanner, so that the body cannot be archived normally after the seal head is disassembled and taken out, thereby avoiding theft and abuse of the seal and effectively ensuring the safety of the seal.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4As shown, a smart seal with an anti-theft function includes a shell 1, a seal tube 2, a seal head 3, a body 4, a high-speed scanner 5 and a lifting mechanism. In this embodiment, a camera is provided on the high-speed scanner 5 for taking photos of the stamped documents. A storage module is provided in the body 4 for archiving the stamped documents (if the stamped documents are not archived, they are considered invalid documents). The seal tube 2 is installed at the top of the shell 1, and the seal head 3 is located in the seal tube 2. A buckle 19 for limiting the position of the seal head 3 is installed at the top of the seal tube 2 to improve the position stability of the seal head 3 in the seal tube 2.

[0022] The seal tube 2 includes a cylinder body 201 and a ring 202. The ring 202 is fixedly sleeved on the outer cylinder wall of the cylinder body 201 near the top. The bottom end of the ring 202 is connected to a second spring 17. The second spring 17 is sleeved on the outside of the cylinder body 201 and installed inside the shell 1 to facilitate elastic support of the seal tube 2.

[0023] The high-speed scanner 5 is installed at the top of the body 4, and a battery 13 for powering the high-speed scanner 5 is provided in the body 4. In the present embodiment, the battery 13 is electrically connected to a charging line (not shown in the figure) for charging, so as to facilitate charging of the battery 13. The body 4 is connected to the seal tube 2 through a lifting mechanism, and the lifting mechanism includes a tube cover 15 installed at the top of the seal tube 2, and the tube cover 15 covers the seal head 3, and a connecting plate 16 is fixedly installed at the top of the tube cover 15. An electric push rod for controlling the lifting and lowering of the connecting plate 16 is provided in the body 4, and the electric push rod is electrically connected to the battery 13, so as to facilitate the control of the lifting and lowering of the seal tube 2, and cooperate with the seal head 3 to facilitate stamping of documents.

[0024] The seal cylinder 2 is symmetrically provided with fixed blocks 6 for supporting the seal head 3, and the two fixed blocks 6 are provided with a slide groove, and a movable block 7 is provided in the slide groove, one end of the movable block 7 is in contact with the side wall of the seal head 3, and a first spring 8 is installed between the other end of the movable block 7 and the bottom of the slide groove, and a groove 9 corresponding to the fixed block 6 is opened at the side wall of the seal cylinder 2, and a conductive ring 10 is installed in the groove 9, and one end of the movable block 7 is connected to a pull rod 11 passing through the conductive ring 10, and the end of the pull rod 11 is connected to a conductive block 12;

[0025] The two conductive blocks 12 are electrically connected, and a lead wire 18 is wound around the outer wall of the seal tube 2 near the top, and the two ends of the lead wire 18 are respectively connected to the two conductive blocks 12. In this embodiment, the lead wire 18 is long enough and is movably connected to the bottom of the groove 9 to ensure that the lead wire 18 can be pulled normally when the conductive block 12 is reset. The positive and negative poles of the battery 13 are respectively electrically connected to the two conductive rings 10 through wires, and a fuse 14 is connected in series between the positive pole of the battery 13 and the corresponding conductive ring 10.

[0026] The working principle of the utility model is as follows: when the seal head 3 in the seal tube 2 is disassembled and taken out, the compressed first spring 8 will drive the movable block 7 to reset, and the movable block 7 will drive the pull rod 11 to move synchronously, thereby pulling the conductive block 12 to fit the conductive ring 10, so that a loop can be formed between the two conductive rings 10. At this time, the battery 13 will be overloaded and short-circuited, so that the fuse 14 will be disconnected, resulting in an open circuit state between the battery 13 and the high-speed scanner 5. Since the high-speed scanner 5 cannot be powered, the high-speed scanner 5 cannot normally take pictures and archive. Even if the seal head 3 is stolen and stamped on a document, the stamped document cannot be successfully archived in the machine body 4, which will result in the document not being effective even if it is stamped, thereby greatly ensuring the safety of the use of the smart seal.

[0027] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
