Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an emergency lighting centralized power supply locking device, including a main body 1 and a locking mechanism 2. The locking mechanism 2 is fixedly installed inside the main body 1. The main body 1 includes a power box 101, a shell 102, and a mounting plate 103. The shell 102 is fixedly installed on the surface of the power box 101, and the mounting plate 103 is fixedly installed at the rear end of the power box 101.

The safety lock 201 is fixedly installed on the surface of the power supply box 101, the lock cylinder 202 is fixedly installed on the surface of the safety lock 201, and the lock tongue 203 is fixedly installed inside the lock cylinder 202.

[0026] Preferably, the main body mechanism 1 further includes rounded corners 104 and mounting holes 105. The rounded corners 104 are fixedly installed around the power supply box 101, and the mounting holes 105 are fixedly installed at the four corners of the mounting plate 103.

[0027] Preferably, the main body 1 further includes an industrial plug 106 and a signal interface 107. The industrial plug 106 is fixedly installed on one side of the power supply box 101, and a plurality of signal interfaces 107 are fixedly installed on one side of the power supply box 101.

[0028] Preferably, the main body 1 further includes indicator lights 108 and an alarm 109. Several indicator lights 108 are fixedly installed on the surface of the power supply box 101, and an alarm 109 is fixedly installed inside the power supply box 101.

[0029] Preferably, the locking mechanism 2 further includes a latch 204 and a lock cylinder 205, wherein the latch 203 is fixedly connected to the latch 204, and the latch 204 is fixedly connected to the lock cylinder 205.

[0030] Preferably, the locking mechanism 2 further includes a locking groove 206 and a fixing groove 207, the latch 204 is fixedly installed with the locking groove 206, and the safety lock 201 is fixedly installed with the fixing groove 207.

[0031] Working Principle: Material and Protective Performance. The outer casing 102 is typically made of metal, such as steel plate or aluminum alloy. Steel plate casing 102 possesses high strength and toughness, capable of withstanding a certain degree of external impact and preventing damage to the internal structure. Aluminum alloy casing 102 is lightweight and corrosion-resistant, suitable for installation environments where weight is a concern. The surface of casing 102 is generally treated with rust prevention, such as painting or galvanizing, to improve its service life in humid environments.

[0032] The IP protection rating of the enclosure 102 is an important indicator of its protective performance. For emergency lighting centralized power supply locking devices, the protection rating is generally required to be IP30 or higher. IP30 means that it can prevent the ingress of solid objects with a diameter greater than 2.5 mm, but it is not waterproof. In some special environments, such as outdoor or damp locations, higher protection ratings, such as IP54 or IP65, may be required.

[0033] In terms of shape and size design, the housing 102 is mostly rectangular or cubic to facilitate installation in equipment such as distribution boxes and cabinets. Its dimensions are determined by the size and number of internal components and installation requirements. For example, a locking device installed in a standard distribution box may have a length between 300 and 600 mm, a width between 200 and 400 mm, and a height between 150 and 300 mm. The corners of the housing 102 are designed with rounded corners 104 to reduce injury to personnel and surrounding equipment in the event of a collision.

[0034] The mounting structure includes mounting holes 105 on the housing 102 for securing the device to a mounting surface. The location and number of mounting holes 105 are designed according to the size and weight of the device. There are four mounting holes 105, distributed at the four corners or edges of the housing 102. The circular mounting holes 105 facilitate direct bolt fixing. In addition, some housings 102 may also include mounting brackets, which allow the device to be mounted on walls, ceilings, or other supporting structures.

[0035] The lock cylinder 202 is the core component of the locking device, typically employing either a mechanical or electronic design. Mechanical lock cylinders 202 include pin tumbler cylinders and wafer cylinders. A pin tumbler cylinder 202 contains multiple pins, and the arrangement of these pins when a key is inserted controls locking and unlocking. A wafer cylinder 202 uses the shape and position of the wafers to control its opening and closing. An electronic lock cylinder 202 controls the extension and retraction of the bolt 203 via electronic signals, and its unlocking methods can include password input, card swiping, and fingerprint recognition. Electronic lock cylinders 202 offer higher security and convenience, but are also relatively more expensive.

[0036] Lock cylinder 202 is made of copper alloy or stainless steel, materials that offer good wear resistance and corrosion resistance. Lock cylinder 202 requires high precision to ensure smooth key insertion and lock reliability. For example, the dimensional tolerances of the internal pins or blades of lock cylinder 202 are controlled within ±0.05mm to guarantee their proper functioning.

[0037] The latch 203 is connected to the latch 204 and the lock cylinder 202. When the lock cylinder 202 rotates or receives an unlocking signal, the latch 203 extends or retracts accordingly. The latch 203 is generally made of steel, and its hardness and strength are improved through heat treatment processes such as quenching. The latch 203 comes in various shapes, commonly cylindrical and plate-shaped. The cylindrical latch 203 has a simple structure and high reliability; the plate-shaped latch 203 can provide a larger locking area and enhance the locking effect.

[0038] The latch 204 is installed on a component that mates with the locking device, such as the door of a distribution box or the frame of a distribution cabinet. When the latch 203 extends, it inserts into the latch 204 to achieve locking. The material of the latch 204 matches the latch 203, and its opening size precisely matches the size of the latch 203, with a gap generally controlled between 0.5 and 1 mm, to ensure that the latch 203 can be smoothly inserted and securely locked.

[0039] The power input interface for emergency lighting centralized power supply locking devices requires an external power source. This interface is typically a standard industrial 106 plug or a terminal block. The industrial 106 plug is waterproof, dustproof, and prevents mis-plugging; its specifications are selected based on the device's power and voltage requirements. For example, a device with an input voltage of AC220V and a power rating of 1–5kW might use a 16A industrial 106 plug. Terminal blocks offer greater flexibility, accommodating connections to wires of different specifications. They are usually marked to indicate different wiring positions, such as L (live), N (neutral), and PE (ground).

[0040] Signal interface 107 is present in locking devices with electronic lock cylinder 202 or other intelligent functions. Signal interface 107 can be an RS485 interface, CAN interface, or other communication interface for communication with external monitoring systems or other devices. For example, through the RS485 interface, the locking device can send its own status information, such as locking status and fault information, to a remote monitoring center, and can also receive control commands from the remote monitoring center to remotely unlock or lock.

[0041] The internal connection structure connects various components within the device via wires or ribbon cables. The wire specifications are selected based on the current required, typically using copper core wires to ensure good conductivity. Ribbon cables are primarily used to connect chips and components on the circuit board; their flexibility and bendability facilitate wiring within limited space. During the connection process, methods such as soldering, crimping, or pluggable connectors are used to ensure reliable connections.

[0042] Indicator light 108 indicates the working status of the locking device. Common indicator lights 108 include power indicator 108, lock indicator 108, and fault indicator 108. The power indicator 108 is usually green and illuminates when the device is powered on, indicating that the device is in a powered state. The lock indicator 108 is generally red or green; red indicates a locked state, and green indicates an unlocked state. The fault indicator 108 is yellow and illuminates when the device malfunctions, such as a faulty lock cylinder 202 or an abnormal power supply, reminding the user to perform maintenance. The brightness of the indicator lights 108 should be sufficiently conspicuous, generally between 30 and 100 cd / m². 2 It is visible in various lighting conditions and can be clearly seen under different ambient light conditions.

[0043] Alarm 109 is used to issue an alarm signal in abnormal situations. When someone attempts to illegally open the locking device or the device malfunctions seriously, alarm 109 will emit an audible or visual alarm. Alarm 109 can be a buzzer, a speaker, or an audible and visual alarm. A buzzer emits a single sound signal with a frequency between 2 and 5 kHz and a volume between 80 and 100 dB. A speaker can emit an audio alarm message, such as "illegal unlocking." An audible and visual alarm 109 combines flashing lights and an audible alarm for a stronger warning effect.

[0044] For physical protection, the outer casing 102 is constructed of metal to form a physical barrier. Its sufficient strength and toughness can withstand potential external impacts, compression, and other mechanical forces, preventing damage to the internal locking mechanism 2, power supply, and other electrical components. For example, when the device is subjected to an accidental impact, the steel outer casing 102 can disperse the impact force, protecting the internal components from damage. The shape of the outer casing 102 facilitates installation in equipment such as distribution boxes, and the rounded corners 104 prevent sharp injuries to personnel and surrounding equipment during collisions.

[0045] For environmental protection, the housing 102, through rust-proofing treatment, can resist corrosion from humid environments to a certain extent and prevent rusting. For devices with protection rating requirements, the sealing design and structure of the housing 102 can prevent dust, solid foreign objects, and water from entering the device according to the protection rating. For example, for devices with an IP30 protection rating, the opening and gap size design of the housing 102 can prevent solid objects with a diameter greater than 2.5 mm from entering, thereby protecting internal electrical components from interference from dust and larger foreign objects and ensuring the normal operation of the device.

[0046] The installation and fixing principle is that the mounting holes 105 on the outer casing 102 are used to firmly fix the device to the mounting surface through bolts and other connecting parts. The distribution of the mounting holes 105 ensures the stability of the device after installation.

[0047] The pin tumbler lock cylinder 202, when the correct key is inserted, the key's teeth push the pins inside the cylinder to the appropriate positions, aligning the height difference of the pins with the shear line inside the cylinder. At this point, the cylinder 202 can rotate freely, driving the bolt 203 to extend and retract via the connecting structure. For example, when the key is inserted, each pin is pushed to a position that allows the cylinder 202 to rotate precisely, much like a precise key opening a complex mechanical lock.

[0048] The leaf lock cylinder 202 unlocks by changing the position of the leaf when a key is inserted. The key's teeth match the shape of the leaf; when the key is inserted, the leaf is pushed to the correct position, clearing the internal passage of the lock cylinder 202 and allowing it to rotate. The rotating lock cylinder 202, through a mechanical linkage mechanism, controls the extension or retraction of the bolt 203, thus locking or unlocking.

[0049] When the latch 203 extends, it inserts into the corresponding latch 204. The shape and size of the latch 203 are designed to accurately insert into the latch 204 and provide sufficient friction or mechanical resistance after insertion to prevent the latch 204 from accidentally disengaging. For example, a plate-shaped latch 203, after being inserted into the latch 204, has a larger contact area that can withstand greater pulling force, ensuring a secure lock. The opening size of the latch 204 precisely matches the latch 203. Under normal circumstances, the latch 203 can be inserted smoothly, but in the locked state, external pulling force makes it difficult for the latch 203 to disengage from the latch 204.

[0050] The industrial plug 106, when inserted into a corresponding socket, ensures tight contact between the plug's prongs and the socket's holes. The prongs connect to different power lines, such as the live wire, neutral wire, and ground wire, respectively, and external power is introduced into the device through internal conductors. The waterproof, dustproof, and mis-insertion prevention design of the industrial plug 106 ensures the safety and reliability of the connection. For example, the plug's prongs are surrounded by sealing rubber rings to prevent moisture ingress, and its special shape and size design prevents accidental insertion into incompatible sockets.

[0051] For terminal blocks, after stripping a certain length of the external wire, insert the wire into the corresponding position of the terminal block, and then secure the wire by tightening the screw or using tools such as wire crimping pliers. The metal contacts inside the terminal block make close contact with the wire, ensuring good conductivity. Different wiring positions, such as L, N, and PE, are clearly marked on the terminal blocks for easy and correct wiring. For example, when connecting a live wire, insert the wire into the terminal block marked L, tighten the screw, and the current from the live wire can smoothly enter the device through the terminal block.

[0052] When the device connects to external devices via a communication interface such as RS485, data signals are transmitted between two signal lines A and B in the form of differential signals. When sending data, the interface circuit converts the internal digital signal into a differential signal conforming to the RS485 standard and sends it to the external device through the signal lines. When receiving data, the interface circuit detects the voltage difference between signal lines A and B, converts it into a digital signal, and then transmits it to the device's internal control circuit for processing. For example, a locking device can send its locking status information to a remote monitoring center via the RS485 interface, allowing the monitoring center to determine whether the device is locking correctly based on the received signal.

[0053] The power indicator light 108 is used when the device is powered on. Current from the power circuit flows through a current-limiting resistor, driving the green LED to illuminate. The current-limiting resistor limits the current flowing through the LED, preventing damage due to excessive current. For example, in a typical circuit, the power supply is connected to the positive terminal of the LED through a current-limiting resistor of several hundred ohms, while the negative terminal is grounded. When power is input, the LED lights up, indicating that the device is powered on.

[0054] The locking indicator light 108's on / off state is controlled by the status signal of the locking mechanism 2. When the locking mechanism 2 is in the locked state, it outputs a signal, which can be a mechanical switch signal or an electronic signal. This signal drives the control circuit to illuminate a red LED, indicating that the device is locked. Conversely, when the device is unlocked, the control circuit drives the green LED to illuminate. For example, in the electronic lock cylinder 202, the circuitry inside the lock cylinder 202 sends a signal to the indicator light 108 control circuit when locking or unlocking, controlling the corresponding LED to illuminate.

[0055] The fault indicator light 108 is located within the device and is equipped with various fault detection circuits. When a fault is detected, such as a malfunction in the lock cylinder 202 or an abnormal power supply, the fault detection circuit outputs a signal. This signal drives a yellow LED to illuminate via the control circuit, alerting the user to the device malfunction. For example, when the power supply voltage exceeds the normal range, the voltage detection circuit outputs a high-level signal, causing the fault indicator light 108 to light up.

[0056] Alarm 109, when triggered, outputs a pulse signal to the buzzer via its control circuit. The buzzer contains a piezoelectric ceramic plate or an electromagnetic coil. Upon receiving the pulse signal, the piezoelectric ceramic plate vibrates or the electromagnetic coil drives the diaphragm to vibrate, producing sound. The frequency and volume of the sound are determined by the buzzer's inherent characteristics and the parameters of the input signal. For example, if the control circuit outputs a pulse signal with a frequency of 2–5 kHz, the buzzer will emit a sound at the corresponding frequency, with a volume between 80 and 100 dB, used for alarm activation.

[0057] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
