Technical Field
[0001] This invention relates to the field of sign light technology, specifically a tunnel fire safety sign light with a built-in power supply. Background Technology
[0002] Tunnel fire safety signs are lighting devices installed in tunnel structures for safety directional guidance. They are typically fixed to the tunnel walls with bolts.
[0003] If a traditional tunnel fire safety sign light malfunctions, the entire sign light needs to be disassembled for repair or replacement. Disassembling and repairing a faulty sign light is inconvenient, inefficient, and will also affect the normal use of the sign light. Summary of the Invention
[0004] To address the problems of inconvenient disassembly and maintenance, low efficiency, and disruption to normal operation of traditional fault indicator lights, this invention provides the following technical solution: a tunnel fire indicator light with a built-in power supply, comprising a lamp housing, a lamp module installed inside the lamp housing, the lamp module being vertically slidably mounted on the surface of a support plate, and the support plate being slidably mounted inside the lamp housing via a horizontal guide groove.
[0005] The upper surface of the lamp housing is provided with several lamp slots, and the upper surface of the lamp module is equipped with several lamp beads. The several lamp beads on the upper surface of the lamp module are adapted to the corresponding several lamp slots.
[0006] The lamp module is installed or removed from the side of the lamp housing. When installing or removing the lamp module, the lamp beads on the upper surface of the lamp module can cooperate with or separate from the corresponding lamp slot.
[0007] Furthermore, a guide post is fixedly provided on the side surface of the lamp module, a guide rod is slidably provided on the bottom of the support plate, and a push plate is fixedly provided at one end of the guide rod near the outer side of the lamp housing;
[0008] A support block is fixedly installed inside the lamp housing. A slider is slidably installed at the bottom of the support block. When the guide rod slides, it can push the slider to move. Push rods are fixedly installed on both sides of the slider. A rack is slidably installed on both inner walls in the width direction of the lamp housing. The rack is fixedly connected to the push rod. A gear one is rotatably installed on the inner wall of the lamp housing. The gear one meshes with the tooth surface of the lower surface of the rack. A gear two is coaxially fixedly installed on the side of the gear one. A top rod is slidably installed up and down on the inner wall of the lamp housing. The tooth surface of the side surface of the top rod meshes with the gear two. A top block is fixedly installed at the upper end of the top rod. When the top block moves upward, it can push the guide post to move together.
[0009] A reset spring is provided between the lamp module and the support plate.
[0010] Furthermore, the inner wall of the lamp housing is provided with a vertical guide groove, and when the lamp bead corresponds to the lamp groove on the upper surface of the lamp housing, the guide post corresponds to the corresponding vertical guide groove.
[0011] Furthermore, the support block is internally equipped with a limiting component. When installing the lamp module, the limiting component is used to restrict the slider from resetting. When disassembling the lamp module, the limiting component releases the restriction on the slider's resetting.
[0012] Furthermore, the limiting component includes a limiting post, a limiting rod, and a limiting block;
[0013] The limiting post is fixedly installed on the upper surface of the slider. A circular groove is opened inside the support block. The limiting rod is rotatably installed inside the circular groove. The limiting block is slidably installed inside the support block. The limiting block restricts the rotation of the limiting rod and the limiting rod restricts the reset of the limiting post.
[0014] Furthermore, the limiting block is L-shaped, and one end of the limiting block near the outside of the support block can slide into the circular groove. The upper surface of the limiting post is provided with a friction ring that rotates in one direction. The friction ring is in frictional contact with the limiting block. When the limiting post is reset, the friction ring drives the limiting block to reset together.
[0015] There are two limiting rods, which are 180° apart. A magnetic block one is provided at the free end of each limiting rod, and a magnetic block two is fixedly installed inside the circular groove. When the limiting rod slides out of the circular groove, the magnetic block two interacts with the magnetic block one, allowing the limiting rod to rotate.
[0016] Furthermore, the lamp module has two sets, and the two sets of lamp modules are independently installed or removed from both sides of the lamp housing.
[0017] Furthermore, the lamp module has a built-in power supply installed inside, and the lamp housing has detachable side plates on both sides.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. This tunnel fire safety sign light with built-in power supply modularizes the light-emitting components through a combination design of the light module and support plate. Utilizing the cooperation of the push plate, guide rod, and slider, as well as the linkage between the push rod, rack, gear one, gear two, top rod, and top block, the LED beads on the upper surface of the light module can be assembled with the lamp slots on the lamp housing surface. This allows for convenient installation and disassembly of the light module. When the light module needs maintenance, it is not necessary to disassemble the entire sign light; the light module can be removed simply from the side of the lamp housing. The convenient disassembly and maintenance operation improves the efficiency of maintenance and replacement. The design of two sets of light modules ensures that if one set malfunctions and needs repair, the other set can continue to operate, guaranteeing the normal use of the sign light.
[0020] 2. This tunnel fire-fighting sign light with built-in power supply, by setting a circular groove, a limiting rod, a magnetic block and a limiting block inside the support block, and cooperating with the limiting post, can realize the reset restriction of the slider, and at the same time facilitate the release of the slider reset restriction, so as to realize the purpose of installing or removing the light module by pushing the push plate. The installation or removal operation of the light module is convenient and quick. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] An example of this tunnel fire safety sign light with a built-in power supply is as follows:
[0031] Please see Figures 1-7 A tunnel fire safety sign light with a built-in power supply includes a lamp housing 1. Mounting holes are provided on both sides of the lamp housing 1 in the width direction. The sign light is installed in the tunnel by using bolts to cooperate with the mounting holes. A lamp module 2 is installed inside the lamp housing 1. The lamp module 2 is vertically slidably mounted on the surface of a support plate 3. A return spring is provided between the lamp module 2 and the support plate 3. The support plate 3 is used to support the lamp module 2 for installation. The support plate 3 is slidably mounted inside the lamp housing 1 through a horizontal guide groove 101.
[0032] The upper surface of the lamp housing 1 has several lamp slots arranged in an arrow shape. The upper surface of the lamp module 2 is equipped with several lamp beads 21 arranged in an arrow shape. The lamp beads 21 on the upper surface of the lamp module 2 are matched with the corresponding lamp slots. When the lamp beads 21 are lit, the lamp beads 21 form an indicator light.
[0033] It should be noted that a guide post 23 is fixedly provided on the side surface of the lamp module 2, and a vertical guide groove 102 is provided on the inner side wall of the lamp housing 1. When the lamp bead 21 corresponds to the lamp groove on the upper surface of the lamp housing 1, the guide post 23 corresponds to the corresponding vertical guide groove 102. The vertical guide groove 102 is used for the vertical guidance and horizontal limiting of the guide post 23. A guide rod 41 is slidably provided at the bottom of the support plate 3. A push plate 4 is fixedly provided at one end of the guide rod 41 near the outside of the lamp housing 1. The push plate 4 is used to push the guide rod 41 to slide. There is a sliding stroke between the guide rod 41 and the support plate 3. When the push plate 4 is pulled to the outside of the lamp housing 1, the push plate 4 can drive the support plate 3 to move through the guide rod 41.
[0034] A support block 5 is fixedly installed inside the lamp housing 1. A slider 6 is slidably installed at the bottom of the support block 5. When the guide rod 41 slides, it can push the slider 6 to move. A compression spring for resetting the slider 6 is provided between the slider 6 and the support block 5. Push rods 61 are fixedly installed on both sides of the slider 6. A rack 7 is slidably installed on both sides of the inner wall of the lamp housing 1 in the width direction. The rack 7 is fixedly connected to the push rod 61. A gear 8 is rotatably installed on the inner wall of the lamp housing 1. The gear 8 meshes with the tooth surface of the lower surface of the rack 7. A gear 81 is coaxially fixedly installed on the side of the gear 8. A top rod 9 is slidably installed up and down on the inner wall of the lamp housing 1. The tooth surface of the side surface of the top rod 9 meshes with the gear 81. A top block 91 is fixedly installed at the upper end of the top rod 9. When the top block 91 moves upward, it can push the guide post 23 to move together.
[0035] Specifically, when installing the lamp module 2, the support plate 3 is installed in the horizontal guide groove 101, and the support plate 3 is pushed into the lamp housing 1 by the push plate 4 until the lamp module 2 contacts the support block 5. At this time, the lamp bead 21 corresponds to the lamp groove, the guide post 23 corresponds to the vertical guide groove 102, and the guide rod 41 contacts the slider 6. The push plate 4 is pushed further, and the push plate 4 pushes the slider 6 to move through the guide rod 41. The slider 6 drives the rack 7 to move through the push rod 61. The rack 7 meshes with the first gear 8, which drives the second gear 81 to rotate. The second gear 81 meshes with the tooth surface of the top rod 9, which drives the top block 91 to move. The top block 91 pushes the guide post 23 to move towards the upper surface of the lamp housing 1. The guide post 23 drives the lamp module 2 to move together, and the lamp bead 21 will extend out of the lamp groove to emit light to the outside.
[0036] It should also be noted that the support block 5 is equipped with a limit component. When installing the lamp module 2, the limit component is used to restrict the slider 6 from resetting. When disassembling the lamp module 2, the limit component releases the restriction on the slider 6 from resetting.
[0037] The limiting assembly includes a limiting post 62, a limiting rod 52, and a limiting block 54. The limiting post 62 is fixedly disposed on the upper surface of the slider 6. A circular groove 51 is provided inside the support block 5. The limiting rod 52 is rotatably installed inside the circular groove 51. The limiting block 54 is slidably disposed inside the support block 5. The limiting block 54 is used to limit the rotation of the limiting rod 52, and the limiting rod 52 is used to limit the reset of the limiting post 62.
[0038] The limiting block 54 is L-shaped, and one end of the limiting block 54 near the outside of the support block 5 can slide into the circular groove 51. The upper surface of the limiting post 62 is provided with a friction ring 621 that rotates in one direction. A ratchet and pawl structure (not shown in the figure) is provided between the friction ring 621 and the limiting post 62 to realize the one-way rotation of the friction ring 621 on the surface of the limiting post 62. The friction ring 621 is in frictional contact with the limiting block 54. When the limiting post 62 is reset, the friction ring 621 drives the limiting block 54 to reset together.
[0039] There are two limiting rods 52, which are 180° apart. The free end of the limiting rod 52 is provided with a magnetic block 521. A magnetic block 53 is fixedly installed inside the circular groove 51. The magnetic block 53 and the magnetic block 521 repel each other. When the limiting block 54 slides out of the circular groove 51, the magnetic block 53 and the magnetic block 521 interact, allowing the limiting rod 52 to rotate.
[0040] Specifically, when the guide rod 41 pushes the slider 6 to move, the slider 6 drives the limiting post 62 to move together. During the movement of the limiting post 62, it pushes away the limiting rod 52 and passes over the limiting rod 52. At this time, the friction ring 621 rolls on the surface of the limiting block 54, so the friction ring 621 will not drive the limiting block 54 to move. After the limiting post 62 passes over the limiting rod 52, the limiting rod 52 re-contacts the limiting block 54 under the action of the magnetic block 53. At this time, the limiting rod 52 will restrict the limiting post 62 from resetting.
[0041] When slider 6 needs to be reset, continue to push slider 6 using guide rod 41. At this time, limit post 62 continues to move and contacts the other end of limit block 54, thereby driving limit block 54 to move until limit block 54 moves out of circular groove 51. At this time, under the action of magnetic block 2 53, limit rod 52 rotates clockwise until the force is balanced. At this time, pull push plate 4 outward, and slider 6 resets under the action of compression spring. When limit post 62 contacts limit rod 52 during the reset process, it will push limit rod 52 to rotate. At the same time, friction ring 621 drives limit block 54 to reset through friction. After limit post 62 is reset, under the action of magnetic block 2 53, another limit rod 52 and the limit rod 52 that previously restricted the movement of limit post 62 exchange positions. When slider 6 is reset, the linked top block 91 is reset together. Under the action of reset spring, lamp module 2 moves towards support plate 3, thereby separating lamp bead 21 from lamp groove, which makes it easier to remove lamp module 2 from lamp housing 1.
[0042] It should be noted that there are two sets of light modules 2. The two sets of light modules 2 are installed or removed independently from both sides of the light housing 1. The two sets of light modules 2 can be used independently. When one set of light modules 2 needs to be replaced or repaired, the other set of light modules 2 can remain in use, thereby ensuring the normal use of the sign light.
[0043] The lamp module 2 has a built-in power supply 22 installed inside. The built-in power supply 22 in the lamp module 2 can provide power to the lamp module 2 in the event of a power outage in the external environment, so as to ensure the normal use of the sign light. The lamp housing 1 has detachable side plates 10 installed on both sides. After the side plates 10 are removed, the lamp module 2 can be installed or removed from the side of the lamp housing 1. When installing or removing the lamp module 2, the lamp beads 21 on the upper surface of the lamp module 2 can cooperate or separate with the corresponding lamp slot.
[0044] Operating principle of tunnel fire safety indicator lights:
[0045] When the sign light is in use, two sets of light modules 2 are installed inside the lamp housing 1. At the same time, the lamp beads 21 on the upper surface of the light module 2 protrude from the upper surface of the lamp housing 1 through the corresponding lamp slots. After the light module 2 is connected to the power supply, the lamp beads 21 emit light. Several lamp beads 21 on the upper surface of the same light module 2 are combined to form an arrow shape, thereby achieving the purpose of directional guidance.
[0046] When the LED chip 21 in lamp module 2 malfunctions or the built-in power supply 22 needs to be replaced, lamp module 2 needs to be removed from the side of lamp housing 1 for maintenance and repair. Specifically:
[0047] Remove the side plate 10 on the corresponding side, and then push the push plate 4 towards the inside of the lamp housing 1. The push plate 4 pushes the slider 6 inward through the guide rod 41. After the slider 6 moves inward a certain distance, the limiting component releases the restriction on the limiting post 62. At this time, pull the push plate 4 outward. The push plate 4 drives the support plate 3 and the lamp module 2 together through the guide rod 41, thereby completing the disassembly of the lamp module 2.
[0048] When it is necessary to install the repaired or new lamp module 2 inside the lamp housing 1, push the support plate 3 into the lamp housing 1 through the horizontal guide groove 101 until the lamp module 2 contacts the support block 5. At this time, push the push plate 4, and the push plate 4 pushes the slider 6 to move through the guide rod 41. Thus, by using the cooperation of the top block 91 and the guide post 23, the lamp beads 21 on the upper surface of the lamp module 2 are matched with the corresponding lamp slot. At the same time, the limiting component inside the support block 5 will limit the slider 6 to reset. At this time, the installation of the lamp module 2 is completed. Then, the side plate 10 can be installed.
[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
