Description

Technical Field

[0001] This utility model relates to the field of tunnel lighting technology, specifically a lighting lamp for traffic tunnels. Background Technology

[0002] Tunnel lighting is a type of lighting equipment used in tunnels and underground passages, primarily to mitigate the visual "black hole effect" or "white hole effect" caused by sudden changes in brightness when vehicles enter or exit tunnels.

[0003] Common tunnel lighting fixtures mainly consist of a lamp body and a lamp holder (see...) Figure 1 The lamp body and the lamp holder are connected by bolts acting as a pivot. When installing tunnel lighting, the lamp holder is fixed first, then the lamp body is rotated to adjust the position of the light beam to avoid the light shining directly on the ground. Then the bolts between the lamp body and the lamp holder are tightened to fix the lamp body by friction. In this method, if the bolts loosen, the friction between the lamp body and the lamp holder will be insufficient, and the lamp body will rotate due to gravity. The rotation of the lamp body will cause the position of the light beam to shift, and in severe cases, it will cause the light to shine directly on the ground.

[0004] Therefore, we propose a traffic tunnel lighting lamp that, once fixed, will not rotate relative to the lamp body and lamp holder. Utility Model Content

[0005] The purpose of this utility model is to provide a lighting lamp for traffic tunnels, so as to solve the problem mentioned in the background art that the lamp body and lamp holder will rotate relative to each other due to loose bolts in the prior art.

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] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1:

[0026] Please see Figure 2-5 This utility model provides a technical solution: a traffic tunnel lighting lamp, including a lamp body 10 and a lamp holder 20. The lamp body 10 includes a light source module, an optical control component, a heat dissipation module, and an intelligent control module (based on existing technology, not described in detail here). The back of the lamp body 10 is rotatably connected to the lamp holder 20. After the lamp holder 20 is fixed, the lamp body 10 can still rotate to adjust the angle. A connecting post 31 is rotatably connected to the back of the lamp body 10. One end of the connecting post 31 is connected to a snap-fit ​​connector 32. The snap-fit ​​connector 32 includes a mating joint 321 and a positioning pin 322. The mating joint 321 is integrally formed with the connecting post 31. The mating joint 321 has a mating groove at the end away from the connecting post 31. A positioning hole is formed through the outer wall of the mating groove. There are two positioning holes, and the central axes of the two positioning holes are collinear.

[0027] The lamp holder 20 is C-shaped, with a reinforcing plate integrally formed on its inner side. A nut sleeve 50 is connected to the front of the reinforcing plate and welded to it. The nut sleeve 50 has a threaded hole perpendicular to the reinforcing plate, and a through-hole is provided on the reinforcing plate, aligned with the threaded hole. A threaded post 42 is inserted into the inner side of the threaded hole and screwed into it. One end of the threaded post 42 passes through the through-hole and is connected to a hexagonal post 43. Installers can place an Allen wrench on the outside of the hexagonal post 43 to easily rotate the threaded post 42. The other end of the threaded post 42 is connected to a snap-fit ​​nut 41. The snap-fit ​​nut 41, threaded post 42, and hexagonal post 43 are integrally molded. The snap-fit ​​nut 41 includes a post head, and a pin hole is opened through the outer circumference of the post head. The post head is inserted into the mating groove of the connector 321, and then the threaded post 42 is rotated so that the pin hole is aligned with the positioning hole. Then, the positioning pin 322 is inserted into the positioning hole and the pin hole to fix the snap-fit ​​nut 41. After the snap-fit ​​nut 41 and threaded post 42 are fixed, they cannot be rotated. The length of the threaded post 42 extending out of the nut sleeve 50 will not change, and the relative angle between the lamp body 10 and the lamp holder 20 will not change.

[0028] Example 2:

[0029] Please see Figure 2-4 6. This utility model provides a technical solution: a traffic tunnel lighting lamp, which adjusts the snap-fit ​​female buckle 41 and snap-fit ​​connector 32 in Embodiment 1. The snap-fit ​​female buckle 41 includes a column head, and a limiting groove is formed on the outer circumference of the column head; the snap-fit ​​connector 32 includes a docking plate 323, a clamping shaft 324, a reset disc spring 325, and an L-post 326. The docking plate 323 has symmetrical movable grooves on both sides. The clamping shaft 324 is rotatably connected to the inner side of the movable groove. The outer end of the clamping shaft 324 is connected to the reset disc spring 325. The outer side of the clamping shaft 324 is sleeved with an L-post 326 connected to the other end of the reset disc spring 325. The reset disc spring 325 is used to drive the L-posts 326 in the movable grooves on both sides to move closer to each other; the other end of the L-post 326 corresponds to the limiting groove.

[0030] When it is necessary to adjust the relative angle between the lamp body 10 and the lamp holder 20, rotate the L-post 326 to move the two L-posts 326 away from each other, and separate the L-post 326 from the limiting groove on the post head. At this time, the snap-fit ​​nut 41 and the threaded post 42 can rotate normally. When it is necessary to fix the relative angle between the lamp body 10 and the lamp holder 20, rotate the L-post 326 to move the two L-posts 326 closer to each other, and insert one end of the L-post 326 into the limiting groove. At this time, the snap-fit ​​nut 41 and the threaded post 42 are restricted and cannot rotate.

[0031] Example 3:

[0032] Please see Figure 2-4This utility model provides a technical solution: a traffic tunnel lighting lamp, based on any embodiment of embodiment one or two, wherein the nut sleeve 50 includes a rectangular sleeve 51, an L-plate 52, a nut 53, a limiting baffle 54, and a pull ring 55. The rectangular sleeve 51 is welded to the reinforcing plate, and a rectangular groove is provided on the inner side of the rectangular sleeve 51. The nut 53 is slidably disposed in the rectangular groove. The nut 53 is rectangular, and the rectangular groove limits the nut 53, allowing it to slide only left and right. The nut 53 is screwed to a threaded post 42.

[0033] Nut 53 includes a left nut 531 and a right nut 533, both of which can slide within a rectangular groove. Each nut is a half-nut; when they come together, they form a complete nut. A thrust spring 532 connects the left and right nuts 531 and 533, pushing them away from each other. After they move away, they are not screwed onto the threaded post 42, allowing the post 42 to move quickly.

[0034] The inner wall of the rectangular sleeve 51 has a through-hole for a baffle. On opposite sides of the left nut 531 and right nut 533, there are compression baffles 534 corresponding to the baffle holes. Both compression baffles 534 pass through the corresponding baffle holes. Two limit baffles 54 are rotatably connected to the outer side of the rectangular sleeve 51, arranged symmetrically. Rotating the limit baffles 54 forces them to compress the compression baffles 534, causing the left nut 531 and right nut 533 to move closer together and abut. A pull ring 55 is connected to the outer side of the limit baffles 54, allowing installers to easily pull the limit baffles 54.

[0035] An L-plate 52 is provided on the outer side of the rectangular sleeve 51. The L-plate 52 is integrally formed with the rectangular sleeve 51. There is a strip gap between the L-plate 52 and the rectangular sleeve 51. The limiting baffle 54 is inserted into the strip gap and will squeeze the extrusion baffle 534. At the same time, the L-plate 52 and the rectangular sleeve 51 are clamped on both sides of the limiting baffle 54, and the reaction force applied by the extrusion baffle 534 to the limiting baffle 54 can prevent the limiting baffle 54 from rotating spontaneously.

[0036] Working principle: First, separate the snap-fit ​​connector 32 from the snap-fit ​​nut 41. Then, rotate the lamp body 10. After the angle between the lamp body 10 and the lamp holder 20 is adjusted, rotate the threaded post 42 so that the snap-fit ​​nut 41 at one end of the threaded post 42 moves toward the snap-fit ​​connector 32. When the snap-fit ​​nut 41 and the snap-fit ​​connector 32 can be connected, connect the snap-fit ​​nut 41 and the snap-fit ​​connector 32. At this time, the snap-fit ​​nut 41 and the threaded post 42 cannot be rotated, and the angle between the lamp body 10 and the lamp holder 20 is fixed.

[0037] It should be noted that the electrical components mentioned in this utility model have had their wiring harnesses combed according to actual conditions during manufacturing, so that the wiring harnesses will not be tangled or affect the operation.
