Description

A type of lighting for rail transit tunnels Technical Field

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

[0002] Rail transit refers to a type of transportation vehicle or system that requires operating vehicles to run on specific tracks. The most typical rail transit is the railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, rail transit has shown more and more types, not only spreading to long-distance land transportation, but also widely used in medium and short-distance urban public transportation.

[0003] For example, CN214468201U discloses a lighting lamp for rail transit tunnels, comprising two columns: each column has a groove on its side facing each other; a first bearing is fixedly embedded in the inner top wall of each groove; a second bearing is fixedly embedded in the inner bottom wall of each groove; a threaded rod is fixedly connected to the inner ring of each set of first and second bearings; and a threaded cylinder is threadedly connected to the outer surface of each threaded rod. This lighting lamp for rail transit tunnels, through the cooperation of an electric telescopic rod and a lampshade, prevents drivers who have just entered the tunnel from inadvertently looking directly at the lamp, which could cause dizziness and potentially lead to accidents. The electric telescopic rod allows the lampshade to be raised and lowered, adjusting the area covered by the lampshade to effectively prevent drivers from looking directly at the lamp and reduce the occurrence of accidents.

[0004] However, in implementing the relevant technology, the above-mentioned lighting for rail transit tunnels has the following problems: it is difficult to buffer the vibrations that cause the lighting to become unusable due to poor reception caused by vibration, which reduces the stability of the lighting; and it is difficult to move and adjust the lighting, which makes it difficult to improve the efficiency of the lighting. Therefore, a lighting for rail transit tunnels is proposed. Summary of the Invention

[0005] This utility model proposes a lighting lamp for rail transit tunnels, which solves the problems in related technologies, such as the difficulty in buffering vibrations that cause the lighting lamp to become unusable due to vibration, reducing the stability of the lighting lamp, and the difficulty in moving and adjusting the lighting lamp, which makes it difficult to improve the efficiency of the lighting lamp.

[0014] Preferably, one end of the threaded rod is fixedly connected to a connecting block, and the four corners of the connecting block are provided with mounting holes.

[0015] Preferably, the buffer assembly includes an airbag, a spring, and multiple dampers, with a circular array of multiple dampers positioned between fixed disk two and fixed disk one.

[0016] Preferably, the spring is sleeved on the outside of the airbag, and the two ends of the spring are respectively fixed between the second fixing plate and the first fixing plate;

[0017] Preferably, the airbag is fixedly connected between the second fixed plate and the first fixed plate, and the airbag is located inside the spring.

[0018] Preferably, the connecting mechanism includes a T-shaped groove II formed on the inner sidewall of the semi-circular frame, and a plurality of T-shaped sliders II slidably engaged inside the T-shaped groove II, the plurality of T-shaped sliders II being arranged sequentially.

[0019] Preferably, an inner threaded sleeve is fixedly installed on one side of the T-shaped slider, and an external threaded post is fixedly connected to the lighting lamp, with the external threaded post and the inner threaded sleeve being threadedly connected.

[0020] Preferably, an L-shaped plate is fixedly installed on one side of each of the plurality of T-shaped sliders, and a hand-twisting screw is threaded through one side of the L-shaped plate, with one end of the hand-twisting screw abutting against one side of the semi-circular frame.

[0021] The working principle and beneficial effects of this utility model are as follows:

[0022] 1.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1

[0035] Please refer to Figures 1-4. A rail transit tunnel lighting lamp includes: a semi-circular frame 1, a mounting mechanism 2, which is disposed on the outer side wall of the semi-circular frame 1. The mounting mechanism 2 includes a first fixing plate 23, a buffer group 24 and a second fixing plate 29, which are disposed between the second fixing plate 29 and the first fixing plate 23; a lamp cover 4; and a lighting lamp 5 fixedly installed inside the lamp cover 4.

[0036] The installation mechanism 2 includes a T-shaped groove 21 on the outer wall of the semi-circular frame 1, a T-shaped slider 22 that is slidably engaged inside the T-shaped groove 21, and a fixed connection between the T-shaped slider 22 and the fixed plate 23. A threaded cylinder rod 25 is fixedly installed on the fixed plate 29. A threaded rod 26 is threadedly connected inside the threaded cylinder rod 25. A connecting block 27 is fixedly connected to one end of the threaded rod 26. Mounting holes 28 are provided through the four corners of the connecting block 27. The buffer group 24 includes an airbag 241, a spring 242 and multiple dampers 243. Multiple dampers 243 are arranged in a circular array between the fixed plate 29 and the fixed plate 23. The spring 242 is sleeved on the outside of the airbag 241. The two ends of the spring 242 are fixed between the fixed plate 29 and the fixed plate 23 respectively. The airbag 241 is bonded and fixedly connected between the fixed plate 29 and the fixed plate 23. The airbag 241 is located inside the spring 242.

[0037] The present invention provides a railway tunnel lighting lamp, which can adjust the length by manually rotating the threaded rod 26, which in turn rotates the threaded rod 26 inside the threaded cylinder rod 25, thereby effectively making the connecting block 27 contact and connect with the inside of the tunnel.

[0038] Push the T-shaped slider 22, and the T-shaped slider 22 will slide inside the T-shaped groove 21 to adjust the support position of the semi-circular frame 1.

[0039] Vibration will occur during the use of the lighting lamp 5. The vibration is buffered by the cooperation of the air bag 241, spring 242 and multiple dampers 243, which effectively prevents the lighting lamp 5 from becoming unusable due to poor reception caused by vibration.

[0040] Example 2

[0041] Based on Embodiment 1, this embodiment includes: a connecting mechanism 3, which is disposed on the inner side wall of the semi-circular frame 1. The connecting mechanism 3 includes a T-shaped groove 31 formed on the inner side wall of the semi-circular frame 1, and multiple T-shaped sliders 32 that are slidably engaged inside the T-shaped groove 31. The multiple T-shaped sliders 32 are arranged sequentially. An inner threaded sleeve 33 is fixedly installed on one side of the T-shaped slider 32. An external threaded post 34 is fixedly connected to the lighting lamp 5. The external threaded post 34 is threadedly connected to the inner threaded sleeve 33. An L-shaped plate 35 is fixedly installed on one side of each of the multiple T-shaped sliders 32. A hand-twisting thread 36 is threaded through one side of the L-shaped plate 35. One end of the hand-twisting thread 36 abuts against one side of the semi-circular frame 1.

[0042] The technical solution provided in this embodiment is as follows: by manually rotating the hand-twisting screw 36, the hand-twisting screw 36 is not in contact with the semi-circular frame 1, so that the T-shaped slider 32 is loosened. After being loosened, the T-shaped slider 32 is pushed, and the T-shaped slider 32 slides inside the T-shaped groove 31 to move and adjust the lighting lamp 5.

[0043] Manually rotate the lamp cover 4 to allow the external threaded post 34 to move within the internal threaded sleeve 33, facilitating the installation, disassembly, or replacement of the lighting lamp 5.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
