Description

Technical Field

[0001] This utility model relates to a high-security seal, and more particularly to a Bluetooth high-security seal. Background Technology

[0002] High-security seals are lead seals used to ensure the safe transport of goods, typically used on containers, trucks, vans, oil tankers, cargo trucks, and doors. The main characteristics of high-security seals include: Anti-counterfeiting features: The lead seal surface of the high-security seal is engraved with a series of codes or number segments, which helps to prevent the seal from being damaged and facilitates better management of the seal's use.

[0003] Material and Structure: The lock body and lock rod of the high-security seal are made of metal. The lock body has an internal spring-loaded structure and the surface is treated with white zinc passivation. The lock body surface is stamped with characters and serial numbers.

[0004] Security: Once the high-security seal is properly applied, it cannot be opened without authorization, and a damaged high-security seal cannot be reused, which greatly enhances its security.

[0005] Wide range of applications: In addition to containers, high-security seals are also suitable for various transportation vehicles and equipment, such as trucks, vans, and oil tankers.

[0006] As can be seen from the above, high-security seals provide an important safety guarantee for modern logistics and transportation. However, for fields with extremely high security requirements, such as international trade and the transportation of dangerous goods, it is essential to maintain the integrity of containers to prevent unauthorized materials or personnel from entering, and to properly seal and maintain the integrity of containers during loading. Therefore, how to further improve the security and reliability of high-security seals has always been a research hotspot in this field. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a Bluetooth high-security sealing strip that can reliably detect the locking and lock rod shearing states while ensuring sealing.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a Bluetooth high-security seal, including a locking rod and a housing. The locking rod is a hollow structure with a first spring inside. A PCB board and a battery are disposed inside the housing. A Bluetooth module, a second spring, and a third spring are disposed on the PCB board. One end of the first spring abuts against the locking rod, and the other end of the first spring abuts against the second spring when the seal is locked. The third spring abuts against the locking rod when the seal is locked. A sensor is disposed on the PCB board to detect the contact state of the second and third springs and sends locking and cutting signals through the Bluetooth module.

[0009] Furthermore, the first spring has hooks with opposite opening directions at both ends. The hook at one end of the first spring contacts the locking rod, and the hook at the other end of the first spring contacts the free end of the second spring that bends inward when locked. The free end of the third spring bends inward and abuts against the outer ring of the locking rod when the seal is locked.

[0010] Furthermore, the first spring is mounted on the spring support and covers the support cover; the first spring and the locking rod are made of metal, and the spring support and the support cover are made of insulating plastic; so that the first spring and the locking rod are electrically connected only at the hook of the first spring.

[0011] Furthermore, a locking sleeve is provided at the end of the locking rod, and a sealing ring is provided in the insertion hole connecting the locking rod and the housing.

[0012] Furthermore, the second and third springs are soldered onto a PCB board, which is then sealed within the housing by potting compound.

[0013] Compared with the prior art, the present invention has the following advantages: the Bluetooth high-security seal provided by the present invention can reliably detect the locking and lock rod shearing states while ensuring sealing. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Figure 1 This is a schematic diagram of the Bluetooth high-security seal structure of this utility model; Figure 2 This is a schematic diagram of the exploded structure of the Bluetooth high-security seal of this utility model; Figure 3 This is a cross-sectional structural diagram of the high-security sealing strip locking rod of this utility model being installed into the female buckle.

[0018] Please see Figure 1 , Figure 2 and Figure 3 The Bluetooth high-security seal provided by this utility model includes a locking rod 1 and a housing 2. The locking rod 1 is a hollow structure with a first spring 7 built in. The housing 2 is provided with a PCB board 5 and a battery 6. The PCB board 5 is provided with a Bluetooth module, a second spring 8 and a third spring 9. One end of the first spring 7 abuts against the locking rod 1, and the other end of the first spring 7 abuts against the second spring 8. The third spring abuts against the locking rod 1 when the seal is locked. The PCB board 5 is provided with a sensor to detect the contact state of the second spring 8 and the third spring 9, and sends locking and cutting signals through the Bluetooth module.

[0019] The Bluetooth high-security seal provided by this utility model has hooks with opposite opening directions at both ends of the first spring 7. The hook at one end of the first spring 7 contacts the locking rod 1. When locked, the hook at the other end of the first spring 7 contacts the free end of the second spring 8 that is bent inward. The free end of the third spring 9 is bent inward and abuts against the outer ring of the locking rod 1 when the seal is locked.

[0020] The Bluetooth high-security seal provided by this utility model has a first spring piece 7 mounted on a spring piece bracket 10 and covering the bracket cover 11. The first spring piece 7 and the locking rod 1 are made of metal, while the spring piece bracket 10 and the bracket cover 11 are made of insulating plastic. This ensures that the first spring piece 7 and the locking rod 1 are electrically connected only at the hook of the first spring piece. Cutting the locking rod breaks the connection point. Figure 3 As shown.

[0021] The Bluetooth high-security seal provided by this utility model has a locking sleeve 3 at the end of the locking rod 1, and a sealing ring 12 is provided in the insertion hole connecting the locking rod 1 and the housing 2; the second spring 8 and the third spring 9 are welded to the PCB board 5, and the PCB board 5 is sealed in the housing 2 by potting glue.

[0022] The Bluetooth high-security seal provided by this utility model works as follows: 1. When locking lever 1 is not inserted into the female latch, the second spring 8 and the third spring 9 remain open. PCB board 5 maintains detection, and during this state, PCB board 5 sends a high-security unused Bluetooth broadcast signal to the outside world.

[0023] 2. After the locking rod 1 is inserted into the female buckle, the second spring piece 8 contacts the first spring piece 7 to form the first contact point 13, the third spring piece 9 contacts the outer ring of the locking rod 1 to form the second contact point 14, and the first spring piece 7 and the locking rod 1 contact at the tail of the locking rod to form the third contact point 15. Figure 3As shown, the three contact points above form the conduction between the second spring 8 and the third spring 9. After the PCB board 5 detects the conduction state, it broadcasts information to the outside world via the Bluetooth module during this period to indicate the conduction state, i.e., the high-security locked state.

[0024] 3. After the locking rod 1 is inserted into the female buckle and the second spring 8 / third spring 9 form a conductive connection, if the tail of the locking rod 1 is cut off, the conductivity between the first spring 7 and the locking rod 1 is broken, and the second spring 8 / third spring 9 will not conduct. After detecting the non-conductivity state, the PCB board 5 sends a message to the outside world via Bluetooth to indicate the non-conductivity state, i.e., the high-security cut-off state.

[0025] 4. After the locking rod 1 is cut off, even if the tail of the locking rod is reattached, the PCB board 5 cannot rebroadcast the high-security locked state via Bluetooth. The PCB board 5 will continue to broadcast the high-security cut-off state.

[0026] The Bluetooth high-security seal provided by this utility model transmits the signal of the locking rod being inserted into the female buckle as follows: PCB board 5 → second spring 8 → first spring 7 → locking rod 1 → third spring 9 → PCB board 5; PCB board 5 can sense the locking and locking rod cutting states. When locked, the following connection method is used: (PCB board - second spring - first spring - locking rod - third spring - PCB board), making the entire structure form a resistance conduction. After PCB board 5 detects the conduction state, it broadcasts information to the outside world via the Bluetooth module during this period to indicate the conduction state, i.e., the high-security lock state.

[0027] After the locking rod is inserted into the female buckle and the second spring 8 / third spring 9 forms a conductive connection, if the tail of the locking rod is cut off, the conductivity between the first spring 7 and the locking rod 1 is broken, and the second spring 8 / third spring 9 will not conduct. After detecting the non-conductivity state, the PCB board 5 sends a message to the outside world via Bluetooth to indicate the non-conductivity state, i.e., the high-security cut-off state.

[0028] The Bluetooth high-security seal provided by this utility model has the following features: 1. Bluetooth high-security device capable of detecting locking status and lock bar breakage status; 2. The PCB board broadcasts the lock bar status to the outside via Bluetooth. 3. The second spring contact 8 and the third spring contact 9 are soldered onto the PCB for easy later production and installation; 4. Encapsulation treatment of the PCB board section of the electronic compartment; 5. Waterproofing of the mechanical compartment is achieved by the sealing ring between the locking rod and the female buckle; 6. Waterproof rating: IP67.

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
