Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting testing technology, and in particular to an auxiliary tool for testing emergency lighting. Background Technology
[0002] Emergency lighting is a core component of fire safety and emergency lighting systems. Its lighting performance (such as light intensity, illumination range, and emergency start-up response speed) is directly related to the safety of personnel evacuation and rescue work in emergency scenarios such as sudden power outages and fires. Currently, some simple testing devices use a structure where a light-shielding sleeve is fixed to the end of a pole. The lighting status of the emergency light is initially judged by observing whether light penetrates the sleeve. However, in practical applications, to adapt to specific lighting needs such as stairwell step lighting and sloping roof factory lighting, a large number of emergency lights are installed at an angle. Since the pole and the light-shielding sleeve of this type of device are rigidly connected in a straight line, the orientation of the sleeve cannot be adjusted according to the tilt angle of the light fixture. Either the sleeve cannot completely fit the tilted light-emitting surface of the light fixture, resulting in gaps at the edges, allowing external light to seep in or light from the light fixture to leak out, making it impossible to accurately judge the light-shielding effect. Therefore, improvements are needed to address these issues. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary tool for testing emergency lighting lamps.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary tool for testing emergency lighting lamps, including a connecting column, a hinge seat fixedly connected to the top of the connecting column, a connecting component rotatably mounted on the pivot of the hinge seat, and a light-transmitting cover installed at one end of the connecting component.
[0005] Preferably, the bottom end of the connecting column has an external thread, and the outer wall of the connecting column has multiple mounting holes equidistantly spaced at the upper end of the external thread. A spring is provided in the mounting hole, and a locking steel ball extending out of the mounting hole is fixed to one end of the spring. A handle is screwed onto the external thread, and a through hole for locking the steel ball is provided on the outer wall of the handle. The lower end of the outer wall of the handle has anti-slip texture.
[0006] Preferably, the connecting assembly includes a turntable coaxially fixed to the pivot of the hinge seat. A connecting block is fixed to one side of the outer wall of the turntable. The connecting block is rectangular, and a rectangular slot is opened at one end facing outward. A rectangular block is inserted into the rectangular slot. One end of the rectangular block is fixed to the outer wall of one end of the light-transmitting cover. A fixing bolt is passed through the top surface of the connecting block. One end of the fixing bolt passes through the top surface of the connecting block and the rectangular block in sequence, and extends to the bottom surface of the connecting block. The top and bottom surfaces of the connecting block are both fixed with internal threaded rings that are screwed to the fixing bolts at the fixing bolt locations.
[0007] Preferably, the outer wall of one side of the hinge seat has a telescopic groove coaxial with the turntable. A telescopic column is movably installed in the telescopic groove. A telescopic pull ring is rotatably installed at one end of the telescopic column. A first rubber ring is sleeved on the outer wall of the telescopic column. The first rubber ring abuts against the inner wall of the telescopic groove. Multiple connecting rods are fixedly connected at equal intervals around one end of the telescopic column. One end of the multiple connecting rods is fixedly connected to a locking plate sleeved on the rotating shaft of the hinge seat. A ring of triangular slots is equidistantly opened on the surface of the turntable opposite to the locking plate. A triangular protrusion corresponding to the triangular slot is raised on the locking plate. An arc-shaped groove for the left and right rotation of the connecting rods is opened on the inner wall of the hinge seat at the multiple connecting rods.
[0008] Preferably, three mounting slots are equidistantly opened on one side of the outer wall of the light-transmitting cover, and each of the three mounting slots is provided with an electric push rod. The telescopic end of the electric push rod is fixedly connected to a fixing block. A C-shaped plate is fixedly connected to one end of the fixing block facing the center of the light-transmitting cover. One end of a connector strip is inserted into two of the three C-shaped plates. A second rubber ring is provided on the outer wall of the rectangular hole formed between the C-shaped plate and the fixing block.
[0009] Preferably, a guide ring is movably provided on the bottom surface of the light-transmitting cover, one part of the guide ring is broken, one end of the two plug strips is provided with an arc-shaped through hole for fitting the guide ring, and an arc-shaped corrugated folded light-blocking sheet is connected between the two plug strips.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model utilizes the rotating engagement of the hinge base and the connecting component's pivot, allowing the connecting component to flexibly rotate the light-transmitting cover around the hinge base. This facilitates adjusting the orientation of the light-transmitting cover according to the tilt angle of the emergency lighting lamp, eliminating the need to forcibly bend the rigid structure. This improves the ease of fitting the light-transmitting cover with the light-emitting surface of the tilted lamp, thereby enabling precise alignment of the light-transmitting cover with lamps at different tilt angles. Furthermore, through the linkage between the telescopic pull ring, telescopic column, connecting rod, and locking plate, pulling the telescopic pull ring can move the locking plate away from the turntable, allowing the light to rotate... After the angle of the moving connection component is adjusted, the telescopic pull ring is released. The elasticity of the first rubber ring pushes the locking plate to reset, causing the triangular protrusion on the locking plate to engage with the triangular slot of the turntable. This facilitates stable locking of the adjusted angle of the connection component, improving the reliability of fixing the angle of the light-transmitting cover and enabling precise locking of the tilt angle of the light-transmitting cover. Ultimately, this solves the problem of light leakage or light penetration caused by gaps due to the inability to adjust the sleeve orientation of existing linear light-shielding devices caused by rigid connections, making it difficult to fit the light-emitting surface of tilted lamps. This improves the adaptability and testing stability of auxiliary tools for tilted lamps. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figures 1 to 4This utility model discloses an auxiliary tool for testing emergency lighting, comprising a connecting column 1, a hinge seat 2 fixedly connected to the top of the connecting column 1, a connecting component rotatably mounted on the pivot of the hinge seat 2, and a light-transmitting cover 3 installed at one end of the connecting component. The connecting column 1 is made of Q235 seamless steel pipe, possessing good load-bearing capacity and bending resistance, ensuring the overall stability of the tool. The hinge seat 2 is made of 45# steel, heat-treated to improve the wear resistance of the pivot. The light-transmitting cover 3 is made of PC board, with low light transmittance and impact resistance, avoiding external light interference during testing while protecting the internal structure. The connecting column 1 provides vertical support for the entire tool, and the hinge seat 2 rotates the connecting component via the pivot, thereby adjusting the angle of the light-transmitting cover 3 to adapt to different tilt angles of emergency lighting. The lighting fixture; the light-transmitting cover 3 can initially cover the light-emitting surface of the lamp, providing a basis for the light-shielding test; the above components together form the basic framework of the device, providing the core support structure for subsequent angle adjustment and light-shielding extension functions; the bottom of the connecting column 1 has an external thread, and the outer wall of the connecting column 1 has multiple mounting holes equidistantly located at the upper end of the external thread. A spring 9 is installed in the mounting hole, and a locking steel ball extending out of the mounting hole is fixed to one end of the spring 9. A handle 4 is screwed onto the external thread, and a through hole for the locking steel ball to extend is opened on the outer wall of the handle 4. The lower end of the outer wall of the handle 4 has anti-slip texture; the spring 9 is made of 65Mn spring steel, which has good elastic recovery and fatigue strength, ensuring that it can still stably push the locking steel ball after long-term use; the locking steel ball is made of GCr15 bearing steel and surface hardened. The tool is treated to be high in hardness and wear-resistant; the handle 4 is made of ABS engineering plastic, which combines rigidity and toughness, and the anti-slip texture on the outer wall increases grip friction; the external thread and the screw connection of the handle 4 allow the handle 4 to move up and down along the connecting post 1, making it easy for the operator to adjust the grip position according to their own height and the installation height of the lamp; the spring 9 pushes the locking ball into the through hole of the handle 4, quickly fixing the position of the handle 4 and preventing it from shifting during use; the anti-slip texture improves grip stability and reduces the risk of the tool slipping; through the above, the convenience and safety of tool operation are improved, adapting to the grip needs in different usage scenarios; the connecting component includes a turntable that is coaxially fixed to the rotating shaft of the hinge seat 2, and a connecting block is fixed to one side of the outer wall of the turntable. The connecting block is rectangular, and the outward-facing end has a rectangular opening. The slot contains a rectangular block, one end of which is fixed to the outer wall of the light-transmitting cover 3. A fixing bolt 7 passes through the top surface of the connecting block, and one end of the fixing bolt 7 passes through the top surface of the connecting block and the rectangular block, extending to the bottom surface of the connecting block. Both the top and bottom surfaces of the connecting block are fixed with internally threaded rings that are screwed onto the fixing bolt 7. The turntable, connecting block, and rectangular block are all made of 45# steel with a galvanized surface treatment for rust prevention and improved structural strength. The fixing bolt 7 is made of 304 stainless steel, possessing good corrosion resistance to prevent rusting and disassembly difficulties over long-term use. The internally threaded ring is made of 40Cr alloy steel, fitting tightly with the fixing bolt 7 to ensure a stable connection. The turntable and the hinge seat 2 are coaxially fixed, providing a basis for the rotation of the connecting components.The rectangular block is inserted into the rectangular slot of the connecting block, and quickly fixed by the screw connection between the fixing bolt 7 and the internal threaded ring, facilitating the installation and replacement of the light-transmitting cover 3. The fixing bolt 7 passes through the connecting block and the rectangular block to ensure connection strength and prevent the light-transmitting cover 3 from loosening during testing. Through the above, the light-transmitting cover 3 is detachable and securely connected, improving the tool's adaptability to different lamps.
[0015] In this utility model, a telescopic groove coaxial with the turntable is opened on one side of the outer wall of the hinge seat 2. A telescopic column is movably installed in the telescopic groove. A telescopic pull ring 5 is rotatably installed at one end of the telescopic column. A first rubber ring is sleeved on the outer wall of the telescopic column and abuts against the inner wall of the telescopic groove. Multiple connecting rods are fixedly connected at equal intervals around one end of the telescopic column. A locking plate sleeved on the rotating shaft of the hinge seat 2 is fixedly connected at one end of the multiple connecting rods. A ring of triangular slots is opened at equal intervals on the surface opposite the turntable and the locking plate. Triangular protrusions corresponding to the triangular slots are raised on the locking plate. Arc-shaped grooves for left and right rotation of the connecting rods are opened on the inner wall of the hinge seat 2 at the multiple connecting rods. The telescopic column, connecting rods and locking plate are all made of 304 stainless steel, which is lightweight and corrosion-resistant, and suitable for long-term exposure to air. The first rubber ring is made of nitrile rubber, which has good elasticity and sealing properties. Its contact with the inner wall of the telescopic groove provides damping force, preventing the telescopic column from sliding freely. The contact surface between the triangular protrusion and the triangular slot is polished to reduce rotational friction. Pulling the telescopic ring 5 moves the telescopic column and locking plate, disengaging the triangular protrusion from the triangular slot and releasing the lock on the turntable, facilitating manual adjustment of the connecting component angle. After releasing the telescopic ring 5, the elasticity of the first rubber ring pushes the locking plate back to its original position, and the triangular protrusion engages with the triangular slot, achieving angle locking. The arc-shaped groove provides ±3° rotation space for the connecting rod, meeting the fine-tuning requirements of the three angles of the light-transmitting cover. Through the above, flexible adjustment and stable locking of the three angles of the light-transmitting cover are achieved, effectively adapting to tilted lamps and improving testing accuracy. Three mounting slots are equidistantly spaced on one side of the outer wall of the photomask 3. Each of the three slots contains an electric actuator 6. A fixing block 11 is fixed to the telescopic end of the electric actuator 6. A C-shaped plate is fixed to the end of the fixing block 11 facing the center of the photomask 3. One end of a connector strip is inserted into two of the three C-shaped plates. A second rubber ring is located on the outer wall of the rectangular hole formed between the C-shaped plate and the fixing block 11. The electric actuator 6 is a miniature electric actuator of model LH-E. The outer shell of the electric actuator 6 is made of aluminum alloy, which is lightweight and has good heat dissipation. The fixing block 11 and the C-shaped plate are made of 6061 aluminum alloy, which is high-strength and easy to process. The connector strip is made of ABS engineering plastic, with a smooth surface for easy insertion. The second rubber ring is made of nitrile rubber to increase the friction between the connector strip and the rectangular hole. Ensure stable installation; the electric push rod 6 can drive the fixed block 11 and the C-shaped plate to extend and retract. The C-shaped plate provides an installation carrier for the plug strip, which facilitates the assembly of the corrugated folded light-blocking sheet 8; the second rubber ring prevents the plug strip from loosening and ensures that the corrugated folded light-blocking sheet 8 is stable in position during the extension process; the three electric push rods 6 are independently controlled and the extension distance of the C-shaped plate can be adjusted according to the extension length of the lamp; through the above, the installation and extension of the corrugated folded light-blocking sheet 8 are provided with power and structural support, realize the extension of the light-blocking range, and adapt to lamps with longer extensions; a guide ring 10 is movably provided on the bottom surface of the light-transmitting cover 3. The guide ring 10 is broken at one point. One end of the two plug strips has an arc-shaped through hole 12 for fitting the guide ring 10. The two plug strips are connected by an arc-shaped corrugated folded light-blocking sheet 8;The corrugated folded light-blocking sheet 8 is coated with a light-shielding coating; the guide ring 10 is made of PP plastic, which has good toughness, and is broken in one place to facilitate assembly and adjustment; the inner wall of the arc-shaped through hole 12 is polished to reduce friction with the guide ring 10; the guide ring 10 provides movement guidance for the connector strip through the arc-shaped through hole 12, preventing the corrugated folded light-blocking sheet 8 from shifting when extending or retracting, ensuring the integrity of the light-shielding area; the corrugated folded light-blocking sheet 8 can extend or fold with the connector strip, extending the light-shielding range of the light-transmitting cover 3 and solving the problem of not being able to cover long-extended lamps; the guide ring 10 is broken in one place to facilitate adjustment of the assembly angle according to the position of the connector strip; through the above, the light-shielding range is flexibly extended, effectively covering long-extended lamps, improving the adaptability of the tool and the reliability of testing.
[0016] Working Principle: Before testing, the operator adjusts the position of handle 4 on the connecting post 1 according to their operating habits and the installation height of the emergency light. Rotating handle 4 utilizes the external thread at the bottom of the connecting post 1 to move handle 4 up and down along the post 1. When handle 4 reaches a comfortable gripping height, the spring 9 in the mounting hole on the outer wall of the connecting post 1 pushes a locking ball out, which engages with the through hole on the outer wall of handle 4, fixing its position. The anti-slip texture on the outer wall of handle 4 increases grip friction, preventing the tool from slipping during testing and providing a stable grip for subsequent operations. Then, the position is adjusted according to the tilt angle of the emergency light. To orient the light cover 3, first pull the telescopic ring 5 outwards. The telescopic ring 5 drives the telescopic column to move outwards along the telescopic groove of the hinge seat 2. At the same time, the telescopic column drives the locking plate to move synchronously through multiple connecting rods, causing the triangular protrusion on the locking plate to disengage from the triangular slot on the turntable, releasing the lock on the turntable. At this time, the operator needs to manually push the connecting assembly, causing the turntable in the connecting assembly to rotate around the axis of the hinge seat 2, thereby causing the connecting block, rectangular block, and light cover 3 to rotate synchronously until the opening direction of the light cover 3 is completely aligned with the light-emitting surface of the tilted lamp. After alignment, release the telescopic ring 5. The elastic restoring force of the first rubber ring pushes the telescopic column back to its original position, and the connecting rod... The moving locking plate moves closer to the turntable, causing the triangular protrusion to re-engage into the corresponding triangular slot, thus locking the tilt angle of the light-transmitting cover 3. The arc-shaped groove on the inner wall of the hinge seat 2 provides ±3° of space for the connecting rod to rotate, satisfying the need for fine-tuning the angle of the light-transmitting cover 3 while preventing excessive rotation that could cause structural jamming. When the lamp's extension length is too long to be fully covered by the light-transmitting cover 3 alone, the corrugated folded light-blocking sheet 8 needs to be extended by the electric push rod 6 to achieve complete light blocking: Activating the electric push rod 6 in the mounting groove on the outer wall of the light-transmitting cover 3 causes the extension end of the electric push rod 6 to push the fixing block 11 and the C-shaped plate outwards from the light-transmitting cover 3. The C-shaped plate is the corrugated folded light-blocking sheet 8. An installation carrier is provided, and one end of the connector strip is inserted into the rectangular hole formed by the two C-shaped plates and the fixing block 11. The second rubber ring on the outer wall of the connector strip can increase the friction with the rectangular hole to ensure a stable installation. As the C-shaped plates and the fixing block 11 extend, the arc-shaped corrugated folded light-blocking plate 8 between the two connector strips unfolds and extends synchronously to make up for the insufficient coverage of the light-transmitting cover 3. At the same time, the guide ring 10 on the inner bottom surface of the light-transmitting cover 3 is broken at one point. The guide ring 10 is fitted onto the connector strip through the arc-shaped through hole 12 to provide guidance for the movement of the connector strip, prevent the corrugated folded light-blocking plate 8 from shifting, and ensure that the extended light-blocking area completely covers the extended light-emitting surface of the lamp.During testing, the operator holds handle 4 and aligns the light-transmitting cover 3 with and covers the luminous surface of the emergency light. If the light fixture extends too far, the remaining area is covered by the extended corrugated folded light-blocking sheet 8. The operator observes whether any light leaks out from the outside of the light-transmitting cover 3 and the corrugated folded light-blocking sheet 8. If no light leaks out, the light fixture is emitting light normally and the light-blocking structure fits tightly, and the light-blocking test is passed. If light leaks out, the extension of the electric push rod 6 can be finely adjusted to further adjust the extension length of the corrugated folded light-blocking sheet 8, or the connecting component can be manually pushed again to adjust the angle of the light-transmitting cover 3 within the ±3° rotation space of the arc groove until no light leaks out. If the light-transmitting cover 3 needs to be replaced... Unscrew the fixing bolt 7 on the top surface of the connecting block. The fixing bolt 7 will unscrew along the internal threads on the top and bottom surfaces of the connecting block, allowing you to remove the rectangular block and the light-transmitting cover 3. Replace the light-transmitting cover 3 and then retighten the fixing bolt 7 to complete the quick replacement. After the test, reverse the electric actuator 6 to retract and reset the C-shaped plate, fixing block 11, and corrugated folded light-blocking sheet 8. Pull out the connector strip and rotate the corrugated folded light-blocking sheet 8 along the folding guide ring 10 to store it. Then pull the telescopic ring 5 to release the lock. Manually push the connecting assembly to rotate the light-transmitting cover 3 to the storage position parallel to the connecting post 1. Release the telescopic ring 5 to lock it. The device is now in use.
