DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The embodiment of the tunnel fire sign light with built-in power supply is as follows: See also Figure 1-Figure 7A tunnel fire sign light with a built-in power supply comprises a lamp housing 1. Both sides of the lamp housing 1 in the width direction are provided with mounting holes. The sign light is installed in the tunnel by using bolts in cooperation with the mounting holes. A lamp module 2 is installed inside the lamp housing 1. The lamp module 2 is vertically slidably arranged on the surface of a support plate 3. A return spring is arranged between the lamp module 2 and the support plate 3. The lamp module 2 is installed and supported by the support plate 3. The support plate 3 is slidably arranged inside the lamp housing 1 through a horizontal guide groove 101.

[0018] The upper surface of the lamp housing 1 is provided with a plurality of lamp grooves, which are distributed in an arrow shape. The upper surface of the lamp module 2 is provided with a plurality of lamp beads 21, which are distributed in an arrow shape. The plurality of lamp beads 21 on the upper surface of the lamp module 2 are matched with the corresponding plurality of lamp grooves. When the lamp beads 21 are lit, the plurality of lamp beads 21 form indicator lights.

[0019] It should be noted that a guide column 23 is fixedly provided on the side surface of the lamp module 2, and a vertical guide groove 102 is provided on the inner 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 column 23 corresponds to the corresponding vertical guide groove 102. The vertical guide groove 102 is used for vertical guidance and horizontal limitation of the guide column 23. A guide rod 41 is slidingly provided at the bottom of the support plate 3. A push plate 4 is fixedly provided at one end of the guide rod 41 close to the outer side of the lamp housing 1. The push plate 4 is used to push the guide rod 41 to slide. A sliding stroke is provided between the guide rod 41 and the support plate 3. When the push plate 4 is pulled toward the outer side of the lamp housing 1, the push plate 4 can drive the support plate 3 to move through the guide rod 41.

[0020] A support block 5 is fixedly installed inside the lamp housing 1, and a slider 6 is slidably provided at the bottom of the support block 5. When the guide rod 41 slides, the slider 6 can be pushed 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. Racks 7 are slidably provided on the inner walls on both sides of the width direction of the interior of the lamp housing 1. The rack 7 is fixedly connected to the push rod 61. A gear 1 8 is rotatably installed on the inner side wall of the lamp housing 1. The gear 1 8 meshes with the tooth surface on the lower surface of the rack 7. A gear 2 81 is coaxially fixedly installed on the side of the gear 1 8. A push rod 9 is slidably provided on the inner side wall of the lamp housing 1. The tooth surface on the side surface of the push rod 9 meshes with the gear 2 81. A push block 91 is fixedly provided on the upper end of the push rod 9. When the push block 91 moves upward, it can push the guide column 23 to move together.

[0021] 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 toward the inside of the lamp housing 1 through 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 column 23 corresponds to the vertical guide groove 102, and the guide rod 41 contacts the slider 6 at the same time, and the push plate 4 continues to be pushed. The push plate 4 pushes the slider 6 to move through the guide rod 41, and the slider 6 drives the rack 7 to move through the push rod 61. The rack 7 is engaged with the gear 1 8, driving the gear 2 81 to rotate, and the gear 2 81 is engaged with the tooth surface on the surface of the top rod 9, driving the top block 91 to move, and the top block 91 pushes the guide column 23 toward the upper surface of the lamp housing 1. The guide column 23 drives the lamp module 2 to move together, and the lamp bead 21 will extend from the lamp groove to emit light to the outside.

[0022] It should also be noted that a limit assembly is provided inside the support block 5 , and when the lamp module 2 is installed, the limit assembly is used to limit the reset of the slider 6 , and when the lamp module 2 is removed, the limit assembly releases the restriction on the reset of the slider 6 .

[0023] The limiting assembly includes a limiting column 62, a limiting rod 52 and a limiting block 54; the limiting column 62 is fixedly arranged on the upper surface of the slider 6, a circular groove 51 is opened inside the support block 5, the limiting rod 52 is rotatably installed inside the circular groove 51, and the limiting block 54 is slidably arranged 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 column 62.

[0024] Among them, the limit block 54 is L-shaped, and one end of the limit block 54 close to the outer side of the support block 5 can slide into the circular groove 51. The upper end surface of the limit column 62 is provided with a unidirectional rotating friction ring 621, and a ratchet pawl structure (not shown in the figure) is provided between the friction ring 621 and the limit column 62 to realize the unidirectional rotation of the friction ring 621 on the surface of the limit column 62. The friction ring 621 is in friction contact with the limit block 54. When the limit column 62 is reset, the friction ring 621 drives the limit block 54 to reset together.

[0025] There are two limit rods 52, which are 180° apart. A magnetic block 1 521 is provided at the free end of the limit rod 52, and a magnetic block 2 53 is fixedly installed inside the circular groove 51. The magnetic block 2 53 and the magnetic block 1 521 repel each other. When the limit block 54 slides out of the circular groove 51, the magnetic block 2 53 interacts with the magnetic block 1 521 to enable the limit rod 52 to rotate.

[0026] Specifically, when the guide rod 41 pushes the slider 6 to move, the slider 6 drives the limit column 62 to move together. During the movement, the limit column 62 pushes the limit rod 52 and passes over the limit rod 52. At this time, the friction ring 621 rolls on the surface of the limit block 54, so the friction ring 621 will not drive the limit block 54 to move. After the limit column 62 passes over the limit rod 52, the limit rod 52 contacts the limit block 54 again under the action of the magnetic block 53. At this time, the limit rod 52 will limit the limit column 62 from resetting.

[0027] When the slider 6 needs to be reset, the guide rod 41 continues to be used to push the slider 6. At this time, the limit post 62 continues to move and contacts the other end of the limit block 54, thereby driving the limit block 54 to move until the limit block 54 moves out of the circular groove 51. At this time, under the action of the second magnetic block 53, the limit rod 52 rotates clockwise until the force state is balanced. At this time, the push plate 4 is pulled outward, and the slider 6 is reset under the action of the compression spring. When the limit post 62 contacts the limit rod 52 during the reset process, it will push the limit rod 52 to rotate. At the same time, the friction ring 621 drives the limit block 54 to reset through friction. After the limit post 62 is reset, under the action of the second magnetic block 53, the other limit rod 52 exchanges position with the limit rod 52 that previously restricted the movement of the limit post 62. When the slider 6 is reset, the linked top block 91 is reset together. Under the action of the reset spring, the lamp module 2 moves in the direction of the support plate 3, thereby separating the lamp bead 21 from the lamp slot, thereby facilitating the removal of the lamp module 2 from the lamp housing 1.

[0028] It should be noted that there are two groups of lamp modules 2, and the two groups of lamp modules 2 can be independently installed or removed from both sides of the lamp housing 1. The two groups of lamp modules 2 can be used independently. When one group of lamp modules 2 needs to be replaced and repaired, the other group of lamp modules 2 can remain in use, thereby ensuring the normal use of the marker light.

[0029] A built-in power supply 22 is installed inside the lamp module 2. The built-in power supply 22 is set in the lamp module 2 to ensure that when the external environment is powered off, the built-in power supply 22 is used to provide power to the lamp module 2 to ensure the normal use of the marker light. Removable side panels 10 are installed on both sides of the lamp housing 1. After the side panels 10 are removed, the lamp module 2 is 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 be matched or separated with the corresponding lamp slot.

[0030] The use principle of tunnel fire sign lights: When the marker light is in use, two groups of lamp modules 2 are installed inside the lamp housing 1. At the same time, the lamp beads 21 on the upper surface of the lamp module 2 protrude from the upper surface of the lamp housing 1 through the corresponding lamp grooves. After the lamp 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 lamp module 2 are combined into an arrow shape to achieve the purpose of direction guidance.

[0031] When the lamp bead 21 in the lamp module 2 has a problem or the built-in power supply 22 needs to be replaced, the lamp module 2 needs to be removed from the side of the lamp housing 1 to perform maintenance on the lamp module 2, specifically: Remove the side panel 10 on the corresponding side, and then push the push plate 4 toward 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 for a certain distance, the limit assembly releases the restriction on the limit column 62. At this time, pull the push plate 4 outward, and 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.

[0032] When it is necessary to install a 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, which pushes the slider 6 to move through the guide rod 41, so that the top block 91 cooperates with the guide column 23 to cooperate with the lamp beads 21 on the upper surface of the lamp module 2 and the corresponding lamp groove. At the same time, the limit assembly inside the support block 5 will limit the reset of the slider 6. At this time, the installation of the lamp module 2 is completed, and then the side panel 10 can be installed.

[0033] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
