Description

Technical Field

[0001] This utility model relates to the field of guardrail locks, specifically to an electronic guardrail lock. Background Technology

[0002] As an important security device, guardrail locks play a crucial role in numerous fields. These include, but are not limited to, guardrails in industrial production areas, public facilities, and maintenance areas. For example, maintenance areas in airports, subways, and high-speed rail stations are often enclosed by guardrails, allowing only internal maintenance personnel to enter. Within the enclosed area, specific entrances are provided for personnel access, and currently, chain locks or padlocks are commonly used. Standard maintenance access door locks include mechanical locks and electric bolt locks.

[0003] However, existing guardrail locks have some obvious drawbacks. For conventional mechanical padlocks, current technology generally lacks a feedback mechanism to indicate whether the guardrail passage is closed when people enter or exit, thus affecting usability and management security. While existing electric bolt locks can sense the position of a magnet on the door side to indicate whether the door is locked or unlocked, this is often compromised in practice due to various problems during installation and use, such as loose door structures leading to misalignment and excessive gaps during opening and closing. This significantly reduces the electric bolt lock's ability to sense door status, affecting the reliability and practicality of locking when users enter or exit the guardrail. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned defects and provide an electronic guardrail lock to address the technical problem that the structure of existing guardrail locks makes it difficult to detect whether the bolt is stably inserted into the locking position, which affects the locking feedback of the guardrail bolt and thus leads to poor performance and security of the guardrail lock.

[0005] The objective of this utility model is achieved through the following means:

[0006] An electronic guardrail lock includes a housing and a circuit board disposed within the housing. The housing has an insertion hole for a latch. A drive unit is mounted on the housing via a receiving groove. The housing has a first sliding groove communicating with the receiving groove. The middle of the first sliding groove is connected to the insertion hole, and a slidable locking piece is disposed within the first sliding groove. The locking piece has a locking hole. The drive end of the drive unit extends into the first sliding groove and connects to one end of the locking piece, allowing the drive unit to drive the locking piece to move along the first sliding groove to lock or unlock. A sensor is disposed within the housing via a second sliding groove. The sensor has a positioning hole communicating with the insertion hole. One end of the sensor extends into the circuit board, and the sensor can move along the second sliding groove. A detection switch for detecting latch insertion or removal is electrically connected to the circuit board. A first elastic member within the housing provides a continuous elastic force to the sensor, moving it away from the detection switch.

[0007] The latch has an insertion end and a locking part. When the insertion end of the latch passes through the locking hole and the positioning hole in sequence along the insertion hole, the sensing plate is pressed by the latch and moves toward the detection switch. The circuit board receives the latch insertion signal, and the driving component drives the locking plate to move along the first slide groove to lock, so that the locking plate is locked by the locking hole and the locking part.

[0008] Furthermore, as described above, one end of the first slide groove is connected to the receiving groove, and the other end of the first slide groove forms a limiting part. The driving member can drive the locking piece to extend and retract along the first slide groove toward the receiving groove through the driving end.

[0009] When the latch is inserted into the socket and the insertion part passes through the positioning hole, the detection switch detects the sensing plate, and the circuit board controls the driving unit to drive the locking plate to retract and move along the first slide groove, so that the locking plate is engaged with the locking plate of the latch through the locking hole, thereby forming a locked state.

[0010] Furthermore, as described above, the locking piece is provided with a connecting end at one end near the driving member. The driving member is connected to the connecting end through the driving end, and the driving end of the driving member is used by a second elastic member to provide a continuous elastic force to the locking piece away from the receiving groove.

[0011] The second elastic element provides a continuous elastic force to the locking piece, moving it away from the receiving groove, further ensuring the stability and reliability of the locking piece.

[0012] Optionally, in some embodiments, the electronic locking method of the moving locking piece driven by the driving element can be energized to lock and de-energized to lock, or energized to lock and de-energized to lock, thereby adapting to different usage needs and improving applicability and practicality.

[0013] Furthermore, as described above, the first slide groove and the second slide groove are arranged in parallel, and the insertion hole is vertically connected to the first slide groove and the second slide groove in sequence.

[0014] Furthermore, as described above, the interior of the box is provided with a mounting slot for mounting a circuit board, and the box is provided with a ribbon cable hole that communicates with the mounting slot.

[0015] Furthermore, as described above, the first elastic element applies a continuous pushing force to the sensing sheet, causing the positioning hole of the sensing sheet and the insertion hole to overlap in an interlaced manner. When the latch passes through the insertion end into the insertion hole and enters the positioning hole, the latch applies a pressing force relative to the first elastic element to the sensing sheet, causing the positioning hole and the insertion hole to be coaxially arranged.

[0016] Specifically, in this embodiment, the insertion hole is a blind hole, and the insertion end of the latch has an inclined chamfer so that the latch can pass through the positioning hole. When the insertion end passes through the positioning hole, the positioning hole and the insertion hole overlap in an intersecting part, and the positioning hole and the insertion hole are coaxially arranged, thereby causing the sensing plate to move towards the detection switch, so as to stably detect the insertion of the latch.

[0017] Furthermore, as described above, the first elastic element and the second elastic element are composed of springs.

[0018] Furthermore, as described above, the electronic lock is configured to operate in either a wired communication mode or a battery-powered wireless communication mode.

[0019] The beneficial effects of this utility model are as follows: When the latch is inserted, its insertion end passes through the locking hole and the positioning hole in sequence and squeezes the sensing plate, forcing the sensing plate to move along the second slide groove and triggering the detection switch. Compared with the traditional magnetic induction method, this physical squeezing triggering mechanism is not affected by the looseness or misalignment of the door structure. Moreover, when the latch insertion end passes through the positioning hole, it can accurately reflect the actual insertion state of the latch, effectively solving the problem of misjudgment caused by the gap in the door body of the electric bolt lock. In addition, the sensing plate continuously receives the elastic force away from the detection switch through the first elastic element. The detection signal is only triggered when the latch is squeezed towards the detection switch during the insertion, ensuring the reliability of the latch insertion state feedback. At the same time, one end of the locking plate is connected to the driving component. When the circuit board receives the latch insertion signal, the driving component drives the locking plate to move along the first slide groove, so that the locking hole and the locking part of the latch form a locking engagement, ensuring that the latch is automatically locked after being inserted into place, improving the locking reliability of the guardrail lock, thereby enhancing the legality of personnel entry and exit and the security of management.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] In this embodiment, refer to Figures 1-6 The electronic fence lock, specifically implemented therein, includes a housing 100 and a circuit board 200 disposed within the housing 100. The housing 100 has an insertion hole 101 for a latch 900 to pass through. A driving member 300 is mounted on the housing 100 via a receiving groove 102. A first sliding groove 103 communicating with the receiving groove 102 is provided within the housing 100. The middle portion of the first sliding groove 103 is connected to the insertion hole 101, and a slidable locking piece 400 is provided within the first sliding groove 103. The locking piece 400 has a locking hole 401. The driving end of the driving member 300 extends into the first sliding groove 103 and connects with the locking piece 400. One end is connected, so that the driving component 300 can drive the locking piece 400 to move along the first slide groove 103 to lock or unlock. The housing 100 is provided with a sensing piece 500 through the second slide groove 104. The sensing piece 500 has a positioning hole 501 that communicates with the insertion hole 101. One end of the sensing piece 500 extends toward the circuit board 200, and the sensing piece 500 can move along the second slide groove 104. The circuit board 200 is electrically connected to a detection switch 600 for detecting the insertion or removal of the latch 900. The housing 100 provides a continuous elastic force to the sensing piece 500 away from the detection switch 600 through the first elastic member 700.

[0029] The latch 900 has an insertion end 901 and a locking part 902. When the insertion end 901 of the latch 900 passes through the locking hole 401 and the positioning hole 501 in sequence along the insertion hole 101, the sensing piece 500 is pressed by the latch 900 and moves toward the detection switch 600. The circuit board 200 receives the insertion signal of the latch 900, and the driving member 300 drives the locking piece 400 to move and lock along the first slide groove 103, so that the locking piece 400 is locked by the locking hole 401 and the locking part 902.

[0030] One end of the first slide groove 103 is connected to the receiving groove 102, and the other end of the first slide groove 103 forms a limiting part. The driving member 300 can drive the locking piece 400 to extend and retract along the first slide groove 103 toward the receiving groove 102 through the driving end.

[0031] When the latch 900 is inserted into the socket 101 and the insertion part passes through the positioning hole 501, the detection switch 600 detects the sensing piece 500, and the circuit board 200 controls the drive unit 300 to drive the locking piece 400 to retract and move along the first slide groove 103, so that the locking piece 400 is engaged with the locking piece 400 of the latch 900 through the locking hole 401, thereby forming a locked state.

[0032] The locking piece 400 has a connecting end 402 near the driving member 300. The driving member 300 is connected to the connecting end 402 through the driving end, and the driving end of the driving member 300 provides a continuous elastic force to the locking piece 400 away from the receiving groove 102 through the second elastic member 800. Specifically, the driving member in this embodiment is an electromagnet.

[0033] The second elastic element 800 provides a continuous elastic force to the locking piece 400 away from the receiving groove 102, further ensuring the stability and reliability of the locking piece 400.

[0034] Optionally, in some embodiments, the electronic locking method of the driving element 300 driving the locking piece 400 can be energized to lock and de-energized to lock, or energized to lock and de-energized to lock, thereby adapting to different usage needs and improving applicability and practicality.

[0035] The first slide groove 103 and the second slide groove 104 are arranged in parallel, and the insertion hole 101 is vertically connected to the first slide groove 103 and the second slide groove 104 in sequence.

[0036] In the specific implementation process, the locking piece 400 and the sensing piece 500 achieve directional movement through the first slide groove 103 and the second slide groove 104 respectively. The slide groove structure forms a rigid constraint on the movement trajectory of the components, avoiding the movement deviation or jamming caused by long-term use, improving the operation smoothness and mechanical durability of the guardrail lock, and adapting to high-frequency opening and closing scenarios.

[0037] The box 100 has an internal mounting slot 105 for mounting the circuit board 200, and the box 100 has a cable hole 106 that communicates with the mounting slot 105.

[0038] The first elastic member 700 applies a continuous pushing force to the sensing plate 500, causing the positioning hole 501 of the sensing plate 500 and the insertion hole 101 to overlap in an intersecting part. When the latch 900 passes through the insertion end 901 into the insertion hole 101 and enters the positioning hole 501, the latch 900 applies a pressing force relative to the first elastic member 700 to the sensing plate 500, so that the positioning hole 501 and the insertion hole 101 are coaxially arranged.

[0039] Specifically, in this embodiment, the insertion hole 101 is a blind hole, and the insertion end 901 of the latch 900 has an inclined chamfer so that the latch 900 can pass through the positioning hole 501. When the insertion end 901 passes through the positioning hole 501, since the positioning hole 501 and the insertion hole 101 form an overlapping part, the positioning hole 501 and the insertion hole 101 are coaxially arranged, thereby causing the sensing plate 500 to move towards the detection switch 600, so that the insertion of the latch 900 can be stably detected.

[0040] In practical implementation, the sensing element 500 continuously receives a spring force away from the detection switch 600 through the first elastic element 700. Only when the latch 900 is inserted is the first elastic element 700 compressed, causing the sensing element 500 to trigger a detection signal. This design effectively prevents false signal transmission due to mechanical vibration or misoperation, ensuring the accuracy of the latch 900 status feedback, while extending the service life of the detection switch 600.

[0041] Conversely, when the latch 900 is pulled out of the socket 101, the sensing plate 500 is pushed by the spring force of the first elastic element 700 to move away from the detection switch 600.

[0042] The first elastic element 700 and the second elastic element 800 are composed of springs.

[0043] In practical implementation, electronic locks can be used in two modes: wired communication with power and wireless communication with battery power. The wired communication mode is suitable for fixed locations, such as airports or other fixed maintenance access points. The wireless battery mode can be used at temporary maintenance points or temporary guardrail locations to further ensure practicality and flexibility.

[0044] In this embodiment, the locking and unlocking processes of the latch 900 are as follows:

[0045] Insertion and locking of latch 900: The housing 100 and latch 900 are installed at the opening / closing entrance of the railing. When latch 900 is inserted into the insertion hole 101, its insertion end 901 passes through the locking hole 401 and the positioning hole 501 in sequence. When the insertion end 901 of latch 900 enters the positioning hole 501, it presses against the sensing plate 500, forcing the sensing plate 500 to move closer to the detection switch 600 along the second slide groove 104, thereby triggering the detection switch 600. This accurately reflects the actual insertion state of latch 900, effectively solving the problem of misjudgment caused by door gaps in electric bolt locks, and ensuring the sensing plate 500... The first elastic element 700 continuously receives elastic force away from the detection switch 600. The detection signal is only triggered when the latch 900 is pushed towards the detection switch 600 during insertion, ensuring the reliability of the latch 900 insertion status feedback. At this time, when the circuit board 200 receives the latch 900 insertion feedback signal, the drive element 300 drives the locking piece 400 to move along the first slide groove 103 towards the receiving groove 102, so that the locking hole 401 and the locking part 902 of the latch 900 form a locking engagement, ensuring that the latch 900 automatically completes locking after being inserted into place, thus improving the locking reliability of the guardrail lock.

[0046] Unlocking the latch 900: The drive unit 300 drives the locking piece 400 to reset, so that the locking hole 401 and the insertion hole 101 are coaxially arranged. At this time, the latch 900 can be pulled out from the insertion hole 101 of the housing 100. When the insertion end 901 of the latch 900 is taken out from the positioning hole 501, the sensing piece 500 is subjected to the elastic reset force of the first elastic member 700, so that the sensing piece 500 moves and resets along the second slide groove 104, thereby causing the sensing piece 500 to disengage from the detection switch 600. The detection switch 600 receives the signal of the latch 900 being removed.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
