[0002] Railway signal lights play a vital role in railway transportation. They use different colors and combinations to indicate key information about train operations, ensuring safe and efficient train operation. When a train approaches, the level crossing signal lights will issue an audible and visual alarm in advance to warn vehicles and pedestrians crossing the railway, thus preventing traffic accidents. At this time, level crossing staff will close the barriers to ensure effective protection.

[0003] Railway signal lights may malfunction during actual use. Once a malfunction occurs, it usually requires immediate replacement and repair. Due to the large size of trains, the consequences can be severe. Therefore, rapid replacement and installation of signal lights is necessary. Traditional railway signal lights are installed using bolts and nuts, requiring tools for disassembly and assembly, hindering quick installation. In urgent situations, the lack of tools can lead to unexpected dangers. Therefore, those skilled in the art have provided a fixing device for railway signal lights to solve the aforementioned problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a fixing device for railway signal lights.

[0005] The present invention provides a fixing device for railway signal lights, which adopts the following technical solution:

[0006] A fixing device for railway signal lights includes a base, a mounting bracket fixedly mounted on the top of the base, a signal light mounted on the top of the mounting bracket, two insert plates fixedly connected to the bottom of the signal light, each insert plate having a slot on its opposite surface, a fixing block fixedly connected to the inner top wall of the mounting bracket, the fixing block having a top opening, and two rotating plates rotatably mounted on the inner top wall of the mounting bracket, one end of each rotating plate passing through a corresponding slot and located within the top opening.

[0007] Preferably, the top of the fixing block has a vertical opening, a bent rod frame is vertically inserted into the opening, a spring is sleeved on the outer surface of the bent rod frame, the spring is set in the vertical opening, a limiting vertical block is fixedly connected to the end of the bent rod frame away from the spring, and a vertical groove is opened in the inner bottom wall of the top opening, the limiting vertical block is slidably connected in the vertical groove.

[0008] Preferably, the limiting vertical block is cylindrical, and the top end of the limiting vertical block extends into the top opening.

For clarity and convenience, the relative dimensions and proportions of the parts shown in the drawings have been exaggerated or reduced in size; any dimensions are merely exemplary and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0019] This utility model discloses a fixing device for railway signal lights.

[0020] A fixing device for railway signal lights includes a base 1, a mounting frame 2 fixedly mounted on the top of the base 1, a signal light 3 mounted on the top of the mounting frame 2, and two insert plates 31 fixedly connected to the bottom of the signal light 3. Both insert plates 31 slide into the interior of the mounting frame 2, and each insert plate 31 has a slot 32 on its opposite side. A fixing block 23 is fixedly connected to the inner top wall of the mounting frame 2, and a top opening 27 is provided on the top of the fixing block 23. Two rotating plates 21 are rotatably connected to the inner top wall of the mounting frame 2, and each rotating plate 21 slides within its corresponding slot 32. The opposite ends of the two rotating plates 21 are located within the top opening 27. Therefore, when the two rotating plates 21 rotate into the top opening 27, they are positioned within their corresponding slots 32, allowing the two rotating plates 21 to limit and fix the two insert plates 31. The rotation of the two rotating plates 21 allows for quick installation and removal of the signal light 3 without the need for tools, facilitating replacement and maintenance.

[0021] A vertical opening 28 is provided at the top of the fixing block 23. A bent rod frame 25 is vertically inserted into the opening 28. A spring 29 is sleeved on the outer surface of the bent rod frame 25. The spring 29 is located inside the opening 28. The top end of the spring 29 is fixedly connected to the bent rod frame 25, and the bottom end of the spring 29 is fixedly connected to the inner bottom wall of the opening 28. A limiting vertical block 24 is fixedly connected to the end of the bent rod frame 25 away from the spring 29. A vertical groove 26 is provided on the inner bottom wall of the top opening 27. The limiting vertical block 24 is slidably connected in the vertical groove 26. The device is cylindrical, with the top of the limiting vertical block 24 extending into the top opening 27, facilitating contact between the limiting vertical block 24 and one side of the two rotating plates 21. This allows the limiting vertical block 24 to limit the two rotating plates 21 located within the top opening 27, preventing the two rotating plates 21 from becoming loose. A lever 22 is fixedly installed on one side of each of the two rotating plates 21, facilitating rotation of the rotating plates 21 via the lever 22. The top of the rotating plate 21 contacts the inner top wall of the mounting bracket 2, and the bottom of the rotating plate 21 slides in contact with the bayonet 32 ​​and the bottom inner wall of the top opening 27.

[0022] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0023] The implementation principle of a fixing device for railway signal lights according to this utility model embodiment is as follows: By sliding the two insert plates 31 at the bottom of the signal light 3 into the interior of the mounting frame 2, the user rotates the two rotating plates 21 in opposite directions by holding two levers 22, causing the two rotating plates 21 to slide into the interior of the corresponding slots 32. By pulling down the bending rod frame 25, the bending rod frame 25 moves downward, which drives the limiting vertical block 24 to move downward under the limitation of the vertical groove 26. The downward movement of the bending rod frame 25 compresses the spring 29. When the limiting vertical block 24 disengages from the interior of the top opening 27, it is easy to rotate the two rotating plates 21 to a horizontal state. The two rotating plates 21 are positioned so that their opposite ends are inside the top opening 27, allowing them to limit the two insert plates 31. This facilitates the stable installation of the signal light 3 on the mounting bracket 2. The limiting vertical block 24 is reset under the action of the spring 29, further limiting the two rotating plates 21. When the signal light 3 needs repair or replacement, the bent rod bracket 25 can be pulled down to allow the limiting vertical block 24 to descend along the vertical groove 26, releasing the limitation on the two rotating plates 21 and making it easy to remove the signal light 3. The overall disassembly and assembly are convenient and quick, requiring no tools, and the signal indication can be quickly restored to normal.
