Description

Technical Field

[0001] This utility model relates to the field of locks, and more specifically, to an anti-disassembly electronic tag lock. Background Technology

[0002] While existing electronic tag locks can record their current unlocked or locked status, they cannot update their status promptly in the event of forced entry or damage. Testing will still show them as locked, hindering effective and reliable management and monitoring of their actual application status by management personnel. This could potentially impact the security of electronic tag locks. Therefore, improving the security performance of electronic tag locks has become a pressing technical issue. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a tamper-proof electronic tag lock, which can improve the security performance of electronic tag locks.

[0004] This utility model provides a tamper-proof electronic tag lock, comprising: an upper housing, a lower housing, a lock channel, and a lock body. The upper housing and the lower housing are connected to form an accommodating space between them, and a PCB circuit is disposed within the accommodating space. One end of the lock channel is provided with a locking port for inserting the lock body into the other end of the lock channel to lock the electronic tag lock. The other end of the lock channel is used for electrical connection with the PCB circuit. The PCB circuit includes a first PCB circuit board and a second PCB circuit board connected by adhesive bonding. The first PCB circuit board is integrally connected to the upper housing, and the second PCB circuit board is integrally connected to the lower housing.

[0005] Optionally, in one embodiment of the present invention, a metal connector is provided at one end of the lock body, and a signal line for matching the PCB circuit is provided inside the metal connector.

[0006] Optionally, in one embodiment of the present invention, the metal connector is covered with a heat shrink tubing so that one end of the signal line abuts against the bottom of the metal connector through the heat shrink tubing.

[0007] Optionally, in one embodiment of the present invention, the outer wall of the heat shrink tubing is coated with epoxy resin so that the electronic tag lock enters the unlocked state when the metal connector is cut.

[0008] Optionally, in one embodiment of the present invention, a locking structure for accommodating the lock body in the unlocked state is further included, the locking structure being disposed on the side of the electronic tag lock.

[0009] Optionally, in one embodiment of the present invention, the locking structure includes an upper locking portion integrally disposed on the side edge of the upper housing and a lower locking portion integrally disposed on the side edge of the lower housing, wherein the upper locking portion and the lower locking portion cooperate to abut against each other to form the locking structure.

[0010] This utility model proposes an anti-disassembly electronic tag lock. It not only features an insertion port at one end of the lock channel for inserting the lock body into the other end, ensuring a stable and reliable locking state, but also incorporates a PCB circuit within the space between the upper and lower housings. This PCB circuit includes a first PCB board and a second PCB board connected by adhesive bonding. The first PCB board is integrally connected to the upper housing, and the second PCB board is integrally connected to the lower housing. Therefore, even if the upper or lower housing of the electronic tag lock is forcibly disassembled, the corresponding PCB board will also separate, resulting in damage and irreparable failure of the PCB circuit. Consequently, the electronic tag lock will appear unlocked during testing. Thus, the electronic tag lock can correctly display an unlocked state even when the outer shell is forcibly disassembled, facilitating effective and reliable management and querying of the actual application status of the electronic tag lock by management or personnel, and further enhancing the security performance of the electronic tag lock.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the anti-tampering electronic tag lock in the locked state according to one embodiment of the present invention. Figure 2 This is a schematic diagram of the unlocked state of an anti-tamper electronic tag lock according to one embodiment of the present invention. Figure 3 This is a partially exploded structural diagram of an anti-tamper electronic tag lock according to one embodiment of the present invention. Figure 4 This is a partially exploded structural diagram of an anti-tamper electronic tag lock according to another embodiment of the present invention; the anti-tamper electronic tag lock may include, but is not limited to:

[0020] The system comprises an upper housing 100, a lower housing 200, a locking channel 300, and a lock body 400. The upper housing 100 and the lower housing 200 are connected to form an accommodating space between them, within which a PCB circuit is disposed. One end of the locking channel 300 is provided with a locking port for inserting the lock body 400 into the other end of the locking channel 300 to lock the electronic tag lock. The other end of the locking channel 300 is used for electrical connection with the PCB circuit. The PCB circuit includes a first PCB circuit board 500 and a second PCB circuit board 600 connected by adhesive bonding. The first PCB circuit board 500 is integrally connected to the upper housing 100, and the second PCB circuit board 600 is integrally connected to the lower housing 200.

[0021] The specific shapes of the upper housing 100 and the lower housing 200 can be set according to the actual scenario, but it is necessary to ensure that the two can be matched and connected. The shape of the lock inlet matches the shape of the lock body 400. The specific type and structure of the PCB circuit can be set by those skilled in the art according to the actual scenario. In this embodiment, it is used to realize the normal operation of the electronic tag lock and is not the main inventive point of this embodiment, so it will not be described in detail here.

[0022] It can be seen that, as Figure 1As shown, not only is an insertion port provided at one end of the lock channel 300 for the lock body 400 to be inserted into the other end of the lock channel 300, enabling the electronic tag lock to reliably enter the locked state, but a PCB circuit is also provided in the accommodating space between the upper housing 100 and the lower housing 200, as shown in the figure. Figure 3 and Figure 4 Since the PCB circuit includes a first PCB circuit board 500 and a second PCB circuit board 600 connected by adhesive bonding, and the first PCB circuit board 500 is integrally connected to the upper housing 100, and the second PCB circuit board 600 is integrally connected to the lower housing 200, even if the upper housing 100 or the lower housing 200 of the electronic tag lock is disassembled by external force, the PCB circuit board on the corresponding housing will also be separated. At this time, the PCB circuit will be damaged and cannot be repaired. Thus, the electronic tag lock will appear to be in the unlocked state during testing. Therefore, the electronic tag lock can correctly display the unlocked state when the outer shell is disassembled by external force, which facilitates the management system or management personnel to effectively and reliably manage and query the actual application status of the electronic tag lock, and helps to further improve the security performance of the electronic tag lock.

[0023] It should be noted that the PCB circuit in the above embodiments may be, but is not limited to, processed by a single-sided bridge, so that the PCB circuit can still work normally when distinguishing between the first PCB circuit board 500 and the second PCB circuit board 600 which are connected by adhesive bonding; when the lock body 400 is not inserted into the lock channel 300, it is in the unlocked state. At this time, the internal circuit of the electronic tag lock does not work, so the battery does not consume power and has a longer storage time.

[0024] In one embodiment, such as Figure 5 As shown, a metal connector 410 is provided at one end of the lock body 400. The metal connector 410 has a signal line 420 for matching the PCB circuit inside. That is, the signal line 420 can be used to make a matching electrical connection with the PCB circuit, ensuring that the metal connector 410 and the PCB circuit are well connected. The metal connector 410 can be, but is not limited to, a steel connector or a steel rod.

[0025] In one embodiment, reference is made to Figure 1 and Figure 5 The metal connector 410 is covered with a heat shrink tubing 430 so that one end of the signal line 420 can be abutted against the bottom of the metal connector 410 through the heat shrink tubing 430. In other words, the heat shrink tubing 430 serves as an intermediate component for buffer connection, so that one end of the signal line 420 can be well connected to the bottom of the metal connector 410, thereby ensuring that the lock body 400 can be stably connected to the PCB circuit when inserted into the lock channel 300.

[0026] In one embodiment, the outer wall of the heat shrink tubing 430 is coated with epoxy resin. Since the epoxy resin hardens after assembly, when the metal connector 410 of the electronic tag lock is cut, the internal signal line 420 will also be cut. After the cut, due to the hardening effect of the epoxy resin, the signal line 420 cannot be soldered and restored, so the real-time data of the electronic tag lock cannot be tested, and the electronic tag lock enters an unlocking state under abnormal conditions.

[0027] In one embodiment, reference is made to Figure 1 and Figure 2 The electronic tag lock may also include, but is not limited to, a locking structure 700 for storing the lock body 400 in the unlocked state. The locking structure 700 is located on the side of the electronic tag lock. By setting the locking structure 700, the lock body 400 can be stored conveniently and effectively, so that when needed, the lock body 400 can be taken out from the locking structure 700 for use at any time, which is convenient and reliable.

[0028] In one embodiment, reference is made to Figures 3 to 5 The locking structure 700 includes an upper locking part 710 integrally disposed on the side edge of the upper housing 100 and a lower locking part 720 integrally disposed on the side edge of the lower housing 200. The upper locking part 710 and the lower locking part 720 cooperate to abut against each other to form the locking structure 700. Through the cooperation of the upper locking part 710 and the lower locking part 720, the lock body 400 can be stably and limited in the locking structure 700, resulting in a better placement effect.

[0029] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
