Description

Technical Field

[0001] This utility model relates to the field of fire emergency lighting technology, specifically to a fire emergency light. Background Technology

[0002] Fire emergency lights, as core equipment providing crucial guidance and illumination for safe evacuation in emergency situations, are widely and indispensable in various buildings in modern society, such as office buildings, shopping malls, hotels, schools, hospitals, and residential buildings. They are like beacons of light in the darkness, a vital line of defense for protecting lives.

[0003] According to the authorization announcement number (CN208418466U), an easy-to-install non-continuous emergency lighting light includes a mounting structure and an emergency lighting box. The mounting structure consists of a wall-mounted plate and a clamping plate, with the clamping plate located on the front side of the wall-mounted plate. A fixing block is located on the back of the emergency lighting box, and a mounting plate is fixedly connected to the fixing block. The mounting plate on the rear side of the emergency lighting box can be fixed between the wall-mounted plate and the clamping plate using adjustment holes and adjusting bolts.

[0004] The structure disclosed in this patent has flaws in practical application, specifically as follows: it uses bolts to fasten the mounting plate on the back of the emergency lighting box between the wall-mounted plate and the clamping plate, a method that is extremely cumbersome in terms of operation. From a mechanical perspective, tightening the bolts requires specialized tools, such as wrenches, a process that consumes a significant amount of time and manpower. Disassembly also requires the reverse operation, loosening each bolt one by one, making the process complex. More importantly, considering that emergency lights are typically installed at heights to achieve optimal lighting coverage and evacuation guidance, installing and removing the bolts in this situation requires workers to use climbing equipment, such as ladders or lifts. Climbing not only increases the difficulty of operation but also introduces numerous safety risks. When performing delicate bolt operations at heights, workers need to maintain relative stability, and the complexity of tool handling can easily distract them, potentially leading to falls or other accidents. Utility Model Content

[0005] The purpose of this utility model is to provide a fire emergency light that addresses the problems of cumbersome installation and dismantling processes in existing fire emergency lights, which require specialized tools, consume a lot of time and manpower, and pose safety hazards when working at heights. This utility model proposes a solution that can greatly simplify the installation and dismantling process of fire emergency lights, reduce manpower input, and reduce safety hazards caused by complex operations when working at heights.

[0006] This utility model is achieved through the following technical solution:

[0007] A fire emergency light includes: a wall-mounted plate; an emergency light body, including an emergency light housing; a quick-connect cylindrical body, fitted to the outer wall of the emergency light housing, with a receiving groove inside; a quick-connect assembly, installed inside the receiving groove; a quick-connect adapter base, installed on the wall-mounted plate; a locking actuator, installed on the quick-connect adapter base; and an unlocking actuator, installed on the quick-connect adapter base, with the unlocking actuator being higher than the locking actuator. During installation, the quick-connect assembly engages between the locking and unlocking actuators. During disassembly, the quick-connect assembly moves onto the unlocking actuator, which can fully push the quick-connect assembly into the receiving groove.

[0008] Furthermore, in this utility model, the quick-connect cylinder body has multiple receiving slots inside, and each of the multiple receiving slots is equipped with a quick-connect component.

[0009] Furthermore, in this utility model, the quick-connect assembly includes an elastic element and a quick-connect member with a beveled structure. One end of the elastic element is connected to the bottom wall of the receiving groove, and the other end of the elastic element is connected to the quick-connect member. The beveled structure of the quick-connect member can abut against the locking actuator, causing the quick-connect member to move a first distance into the receiving groove.

[0010] Furthermore, in this utility model, the aforementioned unlocking actuator is fitted onto the outside of the quick-connect adapter base, and the unlocking actuator can reciprocate along the extension direction of the quick-connect adapter base; the size of the unlocking actuator is larger than the size of the locking actuator; the inclined structure of the quick-connect member can abut against the unlocking actuator, causing the quick-connect member to move a second distance toward the receiving groove, the second distance being greater than the first distance; the unlocking actuator is a truncated cone structure, the inner diameter of the unlocking actuator near the locking actuator is D1, the inner diameter of the unlocking actuator away from the locking actuator is D2, and D1 is greater than D2.

[0011] Furthermore, in this utility model, one end of the aforementioned reset spring is connected to the bottom wall of the receiving groove, and the other end of the reset spring is connected to a quick-connect fitting.

[0012] Furthermore, in this utility model, the surface wall of the aforementioned receiving groove is provided with a linear guide channel along the extension direction, and a linear slider is installed on the outer wall of the quick connector, the linear slider being adapted to the linear guide channel.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] 1. The quick-connect adapter base and quick-connect cylinder are designed to match each other, facilitating the rapid installation and removal of emergency lights. The coordinated operation of the quick-connect components with the locking and unlocking actuators allows the quick-connect components to quickly snap into the locking position during installation and quickly unlock during removal, greatly shortening the installation and removal time of emergency lights, improving maintenance efficiency, and enabling quick replacement of faulty emergency lights in emergency situations.

[0015] 2. The quick-connect assembly consists of an elastic element and a quick-connect piece with an inclined structure. During installation, utilizing mechanical principles, the pressure of the locking actuator on the inclined structure of the quick-connect piece is decomposed into a component force pointing towards the receiving groove, causing the quick-connect piece to move. Afterward, the elastic element pushes the quick-connect piece to reset, and its straight structure forms a stable connection with the locking actuator, preventing the quick-connect piece from moving again. This ensures the firmness of the connection between the quick-connect cylinder and the quick-connect adapter base, improving the stability of the emergency light after installation.

[0016] 3. The unlocking actuator has a truncated cone structure. During disassembly, the quick-connect piece contacts the unlocking actuator, and the pressure applied by the unlocking actuator to the quick-connect piece can generate a large component force pointing into the receiving groove, pushing the quick-connect piece completely into the receiving groove and releasing the lock. The structural design of the unlocking actuator and its mechanical relationship with the quick-connect piece make the disassembly operation simple and efficient, ensuring the smooth progress of emergency light maintenance.

Detailed Implementation

[0024] 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 embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0025] Example

[0026] Please refer to Figures 1 to 4 This utility model provides a fire emergency light. The fire emergency light system consists of an emergency light body 4 and matching installation components. The emergency light body 4 mainly includes an emergency light housing 5, an LED light panel, a control circuit board, and an independent battery. The external 220V AC mains power is first processed by a rectifier and filter circuit to convert the unstable AC power into stable DC power, which is then safely connected to the control circuit board via a relay. The control circuit board accurately outputs pulse width modulation (PWM) signals according to a pre-set program algorithm, thereby precisely controlling the brightness, flicker, and other luminous states of the LED light panel to ensure suitable lighting effects in different emergency scenarios.

[0027] Specifically, the wall-mounted plate 1 is the fundamental support component of the entire fire emergency light installation system. The wall-mounted plate 1 is securely installed on the roof using bolts, welding, or other methods, providing a stable installation platform for subsequent connected components and ensuring the entire emergency light system is firmly fixed in its designated position. The quick-connect adapter base 3 is connected to the surface of the wall-mounted plate 1, serving as the docking component for the quick-connect cylinder 2. The quick-connect adapter base 3 is a key interface for enabling rapid installation and removal of the emergency light. Its structural design matches the quick-connect cylinder 2, providing specific space and guidance for the insertion and fixation of the quick-connect cylinder 2.

[0028] The quick-connect cylinder 2 is installed on the outer wall of the emergency light housing 5. The inner wall of the quick-connect cylinder 2 has a receiving groove 8 for installing the quick-connect assembly. The quick-connect cylinder 2 is the intermediate component connecting the emergency light housing 5 and the quick-connect adapter base 3. Through docking and cooperation with the quick-connect adapter base 3, the quick-connect cylinder 2 enables the rapid installation and removal of the emergency light. The quick-connect assembly is installed inside the receiving groove 8 of the quick-connect cylinder 2 and is the key actuator for achieving rapid connection and locking. The quick-connect assembly can move into the receiving groove 8 when subjected to external pressure and can quickly pop out after the pressure is released. Through cooperation with the locking actuator 6 and the unlocking actuator 7, the installation, fixing, and removal operations of the emergency light are achieved.

[0029] The locking actuator 6 is mounted on the quick-connect adapter base 3. Its main function is to apply pressure to the quick-connect assembly during the insertion of the quick-connect cylinder 2, causing the quick-connect assembly to move a certain distance into the receiving groove 8. After the quick-connect assembly moves to the appropriate position, it cooperates with the locking actuator 6 when the quick-connect assembly pops out, locking the quick-connect cylinder 2 and thus fixing the emergency light housing 5 in the installation position. The unlocking actuator 7 is usually located above the locking actuator 6 and is larger than the locking actuator 6. Its function is that when the emergency light needs to be disassembled, when the operator moves the quick-connect cylinder 2 upwards, the quick-connect assembly contacts the unlocking actuator 7. The unlocking actuator 7 applies greater pressure to the quick-connect assembly, pushing the quick-connect assembly completely into the receiving groove 8, releasing the locking state between the quick-connect assembly and the locking actuator 6, allowing the quick-connect cylinder 2 to smoothly disengage from the locking actuator 6 and the unlocking actuator 7.

[0030] For example, the wall-mounted plate 1 is at the top, providing support for the entire system. The quick-connect adapter base 3 is fixedly connected to the wall-mounted plate 1. The emergency light housing 5 is connected to the quick-connect cylinder 2, which engages and disengages around the quick-connect adapter base 3. The quick-connect assembly is installed inside the quick-connect cylinder 2 and has direct mechanical contact and interaction with the locking actuator 6 and unlocking actuator 7. The locking actuator 6 and unlocking actuator 7 are fixed to the quick-connect adapter base 3 and jointly participate in the locking and unlocking process of the quick-connect assembly.

[0031] In some embodiments of this application, multiple receiving slots 8 are evenly formed inside the quick-connect cylinder 2, and multiple quick-connect components are respectively installed in the corresponding receiving slots 8. Compared with a single quick-connect component, the coordinated operation of multiple quick-connect components can significantly improve the connection stability and reliability. During installation, multiple quick-connect components simultaneously contact the locking actuator 6, which can evenly distribute the force and effectively avoid local stress concentration. When subjected to external impact or vibration, the redundant design of multiple quick-connect components can ensure that even if some components experience temporary abnormalities, the overall connection structure can still remain stable, continuously ensuring a stable connection between the emergency light housing 5 and the quick-connect adapter base 3, greatly enhancing the working performance of the fire emergency light in complex operating environments.

[0032] Please refer to Figure 2 and Figure 3 In some embodiments of this application, the quick-connect assembly, as a key component for the rapid installation and fixing of fire emergency lights, mainly consists of an elastic element 9 and a quick-connect member 10 with a special inclined surface structure 11. When the quick-connect cylinder 2 moves upward, the quick-connect member 10 moves upward synchronously.

[0033] Specifically, during the ascent of the quick-connect cylinder 2, the inclined structure 11 of the quick-connect component 10 first comes into contact with the locking actuator 6. According to the principles of mechanics, when two objects are in contact and there is a relative force, force decomposition occurs. At this time, the pressure exerted by the locking actuator 6 on the inclined structure 11 of the quick-connect component 10 can be decomposed into two component forces according to the parallelogram rule. One component force is directed towards the interior of the receiving groove 8, and it is this component force that causes the quick-connect component 10 to overcome the initial elastic force of the elastic element 9 and move into the receiving groove 8.

[0034] As the quick-connect cylinder 2 continues to rise, when the inclined structure 11 of the quick-connect member 10 is completely out of the range of action of the locking actuator 6, the component force that caused the quick-connect member 10 to move into the receiving groove 8 disappears, and the quick-connect member 10 stops displacing into the receiving groove 8. During this process, the quick-connect member 10 moves a precisely set first distance into the receiving groove 8. It is worth noting that at this time, the quick-connect member 10 is still at least partially outside the receiving groove 8, a design that lays the foundation for subsequent disassembly operations.

[0035] As the quick-connector 10 continues to rise and moves above the locking actuator 6, the elastic element 9, which was originally in a compressed state, begins to recover its elastic potential energy. The elastic force released by the elastic element 9 pushes the quick-connector 10 rapidly outward from the receiving groove 8 until the quick-connector 10 returns to its initial position. The side of the quick-connector 10 away from the inclined structure 11 is a straight structure. After the elastic element 9 pushes the quick-connector 10 out, this straight structure presses tightly against the locking actuator 6. Due to the contact method between the straight structure and the locking actuator 6, even under the action of gravity and other external factors, the force generated by the locking actuator 6 on the quick-connector 10 cannot be decomposed into a component force sufficient to make the quick-connector 10 move back into the receiving groove 8. This stable mechanical structure ensures a reliable connection between the quick-connector 10 and the locking actuator 6, thereby achieving a firm fixation between the quick-connect cylinder 2 and the quick-connect adapter base 3, and ultimately achieving a stable installation of the emergency light housing 5.

[0036] Please refer to Figure 4 In some embodiments of this application, the unlocking actuator 7 has a frustum-shaped structure and is fitted onto the outside of the quick-connect adapter base 3. The unlocking actuator 7 can reciprocate along the axial extension direction of the quick-connect adapter base 3. The size of the unlocking actuator 7 is larger than the size of the locking actuator 6. The inner diameter of the unlocking actuator 7 near the locking actuator 6 is D1, and the inner diameter of the unlocking actuator 7 away from the locking actuator 6 is D2, and D1 is greater than D2. When the emergency light housing 5 is not installed on the quick-connect adapter base 3, the unlocking actuator 7 moves downward under its own gravity until it fits against the locking actuator 6 and is in an initial static state.

[0037] Specifically, during the installation of the emergency light housing 5, the operator pushes the quick-connect cylinder 2 upwards, causing the quick-connect component 10 inside to rise synchronously. The quick-connect component 10 first contacts the locking actuator 6. Under the action of the locking actuator 6, the inclined structure 11 of the quick-connect component 10 is subjected to pressure. According to the principle of force decomposition, this pressure is decomposed into a component force towards the interior of the receiving groove 8, causing the quick-connect component 10 to overcome the elastic force of the elastic element 9 and move a certain distance into the receiving groove 8. However, at this point, the quick-connect component 10 has not completely entered the receiving groove 8.

[0038] As the quick-connector 10 just passes the top of the locking actuator 6, the inclined structure 11 of the quick-connector 10 begins to contact the unlocking actuator 7 due to the larger size of the unlocking actuator 7. As the quick-connect cylinder 2 continues to move upward, the quick-connector 10 moves the unlocking actuator 7 upward along with it. When the quick-connector 10 reaches the appropriate position, under the action of the elastic potential energy released by the elastic element 9, the quick-connector 10 quickly pops out and engages with the gap between the unlocking actuator 7 and the locking actuator 6, thus achieving a secure fixation between the emergency light housing 5 and the quick-connect adapter base 3.

[0039] If it is necessary to disassemble the emergency light housing 5, the operator pushes the quick-connect cylinder 2 upwards. The quick-connect cylinder 2 causes the quick-connect component 10 to continue rising, which in turn causes the unlocking actuator 7 to move upwards as well. When the unlocking actuator 7 moves to its highest position (the unlocking actuator 7 can reciprocate along the extension direction of the quick-connect adapter base 3, and the quick-connect adapter base 3 has a sliding groove along its own axial direction that matches the unlocking actuator 7), it cannot move upwards any further due to structural limitations. At this point, the quick-connect component 10 continues to move upwards relative to the unlocking actuator 7.

[0040] During the upward movement of the quick-connect component 10, the inclined structure 11 of the quick-connect component 10 continuously abuts against the inner wall of the unlocking actuator 7. The pressure exerted by the unlocking actuator 7 on the quick-connect component 10 is decomposed into a component force towards the interior of the receiving groove 8. This component force pushes the quick-connect component 10 a second distance into the receiving groove 8. This distance is greater than the first distance that the quick-connect component 10 moves into the receiving groove 8 during installation, which is sufficient to completely push the quick-connect component 10 into the receiving groove 8, allowing the quick-connect component 10 to smoothly pass over the unlocking actuator 7.

[0041] When the quick-connector 10 moves above the unlocking actuator 7, the external driving force acting on the unlocking actuator 7 disappears, and the unlocking actuator 7 falls downward under the action of gravity until it is once again in contact with the locking actuator 6. At this time, the operator moves the quick-connect cylinder 2 downward, and the quick-connector 10 moves downward accordingly and comes into contact with the unlocking actuator 7. Due to the truncated cone structure of the unlocking actuator 7, its inner diameter gradually decreases from bottom to top. Guided by the inclined surface of the unlocking actuator 7, the quick-connector 10 moves again into the receiving groove 8 until it is completely inside the receiving groove 8. At this time, the quick-connector 10 no longer interferes with the locking actuator 6 and the unlocking actuator 7, and the quick-connect cylinder 2 can smoothly pass through the locking actuator 6 and the unlocking actuator 7, completing the disassembly operation of the emergency light housing 5.

[0042] In some embodiments of this application, when the quick-connect component 10 is subjected to external pressure (such as from the locking actuator 6 or the unlocking actuator 7) and moves into the receiving groove 8, the return spring is compressed, storing elastic potential energy. When the external pressure disappears, the return spring releases the stored elastic potential energy by virtue of its own elastic recovery capability, pushing the quick-connect component 10 out of the receiving groove 8, returning it to its initial position or a specific working position. This ensures that the quick-connect assembly can continuously and stably achieve the function of quick connection and unlocking, providing a strong guarantee for the reliable installation and disassembly of fire emergency lights.

[0043] In some embodiments of this application, during the movement of the quick-connect component 10, the linear slider is tightly embedded in the linear guide channel. When the quick-connect component 10 is subjected to external force, such as during the installation or removal of an emergency light, and displacement occurs due to its interaction with the locking actuator 6 and unlocking actuator 7, the linear slider slides linearly along the linear guide channel. This cooperation between the linear guide channel and the linear slider effectively restricts the movement trajectory of the quick-connect component 10, ensuring that it can only move in a predetermined straight direction, thus preventing the quick-connect component 10 from experiencing unstable movement states such as offset, wobbling, or rotation within the receiving groove 8.

[0044] Working principle:

[0045] Installation Principle: 1. The wall mounting plate 1 is fixed to the roof, supporting the quick-connect adapter base 3 and providing a stable foundation for the system; 2. The quick-connect cylinder 2 on the outside of the emergency light housing 5 has a pre-installed quick-connect assembly in its receiving groove 8; 3. During installation, the quick-connect cylinder 2 aligns with the quick-connect adapter base 3. The quick-connect assembly first contacts the locking actuator 6 and moves into the receiving groove 8 under pressure. After passing the locking actuator 6, it pops out under elastic force and locks between the locking actuator 6 and the unlocking actuator 7, completing the installation of the emergency light.

[0046] Disassembly principle: 1. During disassembly, push the quick-connect cylinder 2 upward to raise the quick-connect assembly; 2. The quick-connect assembly contacts the unlocking actuator 7 above. The unlocking actuator 7, with its structural and size advantages, presses the quick-connect assembly completely into the receiving groove 8, releasing the lock; 3. Move the quick-connect cylinder 2 downward to disengage it from the unlocking actuator 7 and the locking actuator 6, thus realizing the disassembly of the emergency light.
