Abstract
Description
Technical Field
[0001] This utility model relates to the field of indicator light technology, specifically a locomotive door indicator light. Background Technology
[0002] In the early stages of locomotive development, door status indicators were relatively simple, usually indicating whether the door was closed through simple mechanical devices or basic signal lights. Some older locomotives may have simply used a red light to indicate that the door was not closed and a green light to indicate that the door was closed. The structure was relatively simple and the function was relatively limited.
[0003] Currently, common car door indicator lights on the market mainly consist of several parts such as a lamp holder, a lamp cover, and a lamp ring. Although they can achieve the function of indication, they still have the following problems:
[0004] All parts are installed via threaded connections. The indicator lights only have a single function of lighting up, resulting in poor indication efficiency. Furthermore, all wires are connected and installed inside the indicator lights, leading to a complex internal structure that is susceptible to external interference, difficult to maintain, and poses safety hazards. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a locomotive door indicator light.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a locomotive door indicator light, comprising a mounting ring and a rear cover housing. A through hole is provided in the center of the surface of the mounting ring. A semi-transparent top cover is fixedly connected to the inner surface of the through hole. A transparent flange cover is provided at the lower end of the mounting ring. Several evenly distributed mounting screws are provided on the outer side of the surface of the transparent flange cover. The bottom end of the transparent flange cover is fixedly connected to the top end of the rear cover housing. A mounting plate is provided at the lower end of the rear cover housing. The transparent flange cover is fixedly mounted on the mounting plate by mounting screws. The mounting ring surface has through holes for fixing the semi-transparent top cover. This not only serves a decorative purpose, making the locomotive door indicator light more aesthetically pleasing and refined, and enhancing the overall visual appeal, but also provides some protection for the internal light panel components, preventing dust, moisture, and other impurities from directly entering and affecting their normal operation. Compared to some existing technologies that are simple in appearance or lack sufficient protection, this design improves aesthetics while meeting protection requirements. The transparent flange cover is fixed to the top of the rear cover housing with several evenly distributed mounting screws. This connection method ensures structural stability and provides good protection for the internal components, preventing damage to the internal light panel components from external object collisions. At the same time, its transparency does not affect light transmission, ensuring the normal illumination function of the indicator light.
[0007] Preferably, a disassembly port is provided on the outer side of the back of the mounting ring, and several evenly distributed clamping pieces are fixedly connected to the inner side of the back of the mounting ring. An installation groove is provided between the disassembly port and the clamping pieces, and a tight-fitting protrusion is provided at one end of the inner side of the installation groove. The disassembly port on the outer side of the back of the mounting ring greatly improves the convenience of indicator light maintenance and repair. The mounting ring can be easily opened through this disassembly port using a frame remover to directly access the relevant internal components without the need for a complex and tedious overall disassembly process, effectively saving time and effort and improving maintenance efficiency. Moreover, the disassembly port is hidden, and compared with the traditional obviously exposed disassembly port, it does not affect the smoothness of the indicator light's shape and overall coordination. The clamping pieces are tightly engaged with the transparent flange cover, making the connection between the two firm and reliable. Even when encountering vibrations or bumps during locomotive operation, it can effectively prevent the components from loosening or falling off, ensuring the stability of the overall structure of the indicator light. The installation groove and the tight-fitting protrusion at one end of its inner side cooperate with the buckle on the transparent flange cover to play a role in precise installation and stable connection.
[0008] Preferably, one end of the surface of the transparent flange is fixedly connected to a buckle, and the surface of the buckle is in contact with the inner surface of the mounting groove. This design allows the transparent flange to be quickly positioned by the guiding action of the groove, while also having sufficient firmness. The tight fit between the protrusion and the buckle greatly simplifies the installation process, improves assembly efficiency, and also ensures the stability of the connection between the two, ensuring that the transparent flange will not shift or fall off due to vibration or other factors during locomotive operation.
[0009] Preferably, a mounting platform is provided at the lower end of the interior of the rear cover housing. A wire outlet mounting hole is provided in the center of the front of the mounting platform. Limiting angled protrusions are provided on both sides of the wire outlet mounting hole. One end of each of the two limiting angled protrusions is fixedly connected to the front of the mounting platform. A lamp board assembly is provided at the upper end of the interior of the rear cover housing. The mounting platform provides a relatively independent and flat mounting surface for other components, enabling the relevant components to be positioned more accurately and stably during installation, ensuring the reliability of the entire connection system. The wire outlet mounting hole provides a standardized lead-out channel for the installation wires, ensuring that the wires can be neatly and orderly led out from inside the indicator light, avoiding the wires being distributed haphazardly inside the indicator light, affecting the neatness of the internal structure and the safety of the electrical connection. The limiting angled protrusions limit and protect the led-out wires, preventing the wires from being pulled off course and ensuring that the wires always remain in a relatively stable position. It also helps to initially position the wires during installation, enabling the wires to be led out more accurately from the wire outlet mounting hole, improving installation efficiency.
[0010] Preferably, a lead wire is fixedly connected to the inner surface of the outlet mounting hole, and the outer diameter of the lead wire matches the inner diameter of the outlet mounting hole. This matching ensures a tight connection, allowing the lead wire to be securely fixed within the outlet mounting hole. This guarantees a stable electrical connection between the lead wire and the lamp panel assembly and the external electrical system, preventing poor contact due to vehicle movement. This ensures the locomotive door indicator light can receive control signals and accurately display door status information. Furthermore, the outlet mounting hole is located on the side of the rear housing, enabling a side-outlet design. The small space created by the bottom notch of the rear housing allows the lead wire to be easily bent and inserted into the outlet mounting hole, preventing external interference.
[0011] Preferably, the light panel assembly includes an LED light panel, the upper end of which is provided with a light diffuser. A lettering plate is connected to the upper end of the light diffuser, and the upper surface of the lettering plate is fixedly connected to the bottom end of the transparent flange. The light diffuser can redistribute and scatter light through its own optical properties, making the light more uniform and softer after passing through it. This avoids areas of excessive brightness or darkness caused by uneven light, thereby improving the visibility and aesthetics of the indicator light. When the light diffused by the light diffuser shines on the lettering plate, the lettering or other markings on the plate become visible, providing an intuitive textual display method for conveying specific information about the door status. This allows users to quickly and accurately understand the door status through clear textual markings. Furthermore, its close cooperation with components such as the transparent flange ensures that the marking information is presented with good visibility under various lighting conditions, further enhancing the functionality and practicality of the locomotive door indicator light.
[0012] Preferably, a mounting plate through hole is provided in the center of the mounting plate surface, and the axis of the mounting plate through hole is connected to the axis of the rear cover housing. Several evenly distributed screw through holes are provided on the outer side of the mounting plate through hole, and the inner diameter of the screw through holes matches the outer diameter of the mounting screws. This design ensures precise positioning of the rear cover housing when it is installed on the mounting plate, allowing it to be accurately placed in the predetermined position, avoiding installation position deviations, and laying a good foundation for subsequent fixing and installation operations. The precise matching of the screw through holes and the outer diameter of the mounting screws allows the mounting screws to be tightly screwed into the screw through holes, preventing loosening, shaking, or installation failure due to size mismatch during tightening. This ensures the stability of the overall structure of the locomotive door indicator light, preventing indicator light malfunctions or affecting its normal indication function due to loose components. This precise matching design also facilitates installation and maintenance, improving installation efficiency while facilitating the inspection and replacement of internal components, saving maintenance time and costs.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This type of locomotive door indicator light has an engraved plate added above the light diffuser. The engraved text or other markings on the plate are clearly displayed when the light is on, which can accurately show the status of the locomotive door indicator light. The decorative cover and transparent flange cover are rotated and installed. There are no mounting screws on the front of the indicator light, making the indicator light more concise and beautiful. In addition, the side-mounted cable outlet hole is cleverly positioned with a small clamping plate space, which makes it easy to bend the lead wires to enter and exit the cable outlet hole while ensuring that the cable outlet hole is not interfered with by the outside, thus ensuring high safety performance.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Please see Figure 1-8 This utility model provides a locomotive door indicator light, including a mounting ring 2 and a rear cover housing 14. A mounting ring through hole 3 is provided in the middle of the surface of the mounting ring 2. A semi-transparent top cover 1 is fixedly connected to the inner surface of the mounting ring through hole 3. A transparent flange cover 8 is provided at the lower end of the mounting ring 2. A number of evenly distributed mounting screws 10 are provided on the outer side of the surface of the transparent flange cover 8. The bottom end of the transparent flange cover 8 is fixedly connected to the top end of the rear cover housing 14. A mounting plate 19 is provided at the lower end of the rear cover housing 14.
[0026] In use, the mounting ring through hole 3 is installed in conjunction with the semi-transparent top cover 1. The various components are installed in sequence with the transparent flange cover 8 as the positioning center. The semi-transparent top cover 1 protects the internal components on the one hand, preventing dust, water vapor and other impurities from entering directly, and on the other hand, it scatters and filters the light emitted from the inside. The mounting screws 10 fix the transparent flange cover 8 to the mounting plate 19.
[0027] Furthermore, a disassembly port 4 is provided on the outer side of the back of the mounting ring 2, and several evenly distributed clamping pieces 5 are fixedly connected to the inner side of the back of the mounting ring 2. An installation groove 6 is provided between the disassembly port 4 and the clamping pieces 5, and a tight fitting protrusion 7 is provided at one end of the inner side of the installation groove 6.
[0028] When the indicator light malfunctions after long-term operation and its internal components need to be inspected, repaired, or replaced, the operator can easily open the mounting ring 2 through the disassembly port 4 to directly access the relevant internal components without the need for a tedious and complicated overall disassembly process. The clamping piece 5 is tightly engaged with the transparent flange cover 8, effectively preventing the components from loosening or falling off. The mounting slide 6 and the tight-fitting protrusion 7 on one of its inner ends cooperate with the relevant structures on the transparent flange cover 8 to achieve precise installation and a stable connection. The tight-fitting protrusion 7 makes the fit between the buckle 9 and the mounting slide 6 more secure, and at the same time, it limits the buckle 9 at the end of the mounting slide 6.
[0029] Furthermore, a buckle 9 is fixedly connected to one end of the surface of the transparent flange cover 8, and the surface of the buckle 9 is in contact with the inner surface of the mounting groove 6.
[0030] When using the transparent flange cover 8, the buckle 9 fixedly connected to one end of its surface can slide along the mounting groove 6 until the buckle 9 slides to the tight fitting protrusion 7 at one end of the inner side of the mounting groove 6 and fits tightly therewith. The tight fitting protrusion 7 limits the buckle 9 at the tail end of the mounting groove 6.
[0031] Furthermore, a mounting platform 15 is provided at the lower end of the interior of the rear cover housing 14. A cable outlet mounting hole 16 is provided in the center of the front of the mounting platform 15. Limiting angled protrusions 17 are provided on both sides of the cable outlet mounting hole 16. One end of each limiting angled protrusion 17 is fixedly connected to the front of the mounting platform 15. A lamp panel assembly is provided at the upper end of the interior of the rear cover housing 14.
[0032] When in use, the lamp panel assembly emits light. The mounting platform 15 and the wire mounting hole 16 provide a mounting base for the lead wire 18, laying a good electrical connection foundation for the normal operation of the indicator light. The limiting angled boss 17 limits and protects the lead wire 18, effectively preventing the lead wire 18 from being pulled out.
[0033] Furthermore, an outgoing wire 18 is fixedly connected to the inner surface of the outgoing mounting hole 16, and the outer diameter of the outgoing wire 18 matches the inner diameter of the outgoing mounting hole 16.
[0034] During use, the side mounting hole 16 makes it easy to bend and install the lead wire 18 into and out of the mounting hole 16, while ensuring that the lead wire 18 is not easily interfered with by external factors, thus ensuring the efficient operation of the indicator light.
[0035] Furthermore, the light panel assembly includes an LED light panel 11, with a light diffuser 13 at the upper end of the LED light panel 11. A lettering plate 12 is connected to the upper end of the light diffuser 13, and the upper surface of the lettering plate 12 is fixedly connected to the bottom end of the transparent flange cover 8.
[0036] When in use, after being powered on, the LED light panel 11 emits light stably and accurately. The light diffuser 13 homogenizes the light emitted by the LED light panel 11, making the light more uniform and softer after passing through the light diffuser 13. When the light diffuser 13 homogenizes the light emitted by the LED light panel 11 and illuminates the lettering plate 12, the font or logo on the lettering plate 12 is clearly and conspicuously displayed, accurately showing the status of the locomotive door indicator light.
[0037] Furthermore, a mounting plate through hole 20 is provided in the middle of the surface of the mounting plate 19. The axis of the mounting plate through hole 20 is connected to the axis of the rear cover housing 14. Several evenly distributed screw through holes 21 are provided on the outer side of the mounting plate through hole 20. The inner diameter of the screw through holes 21 matches the outer diameter of the mounting screw 10.
[0038] When in use, the operator can easily align the mounting screw 10 with the screw through hole 21 and screw it in smoothly without spending too much time and effort to adjust the matching degree between the mounting screw 10 and the screw through hole 21. When it is necessary to maintain or replace parts of the locomotive door indicator, the mounting screw 10 can also be easily and quickly removed to remove the rear cover housing 14 from the mounting plate 19, which facilitates the inspection, replacement and other operations of internal components.
[0039] In this embodiment, the lead wire 18 is installed in the lead wire mounting hole 16. Then, the LED light board 11, the light diffuser 13, and the lettering plate 12 are installed in sequence inside the rear cover housing 14 to install the lower half of the indicator light. The upper half of the indicator light is then assembled and installed with the transparent flange cover 8 as the positioning center, and the mounting ring 2, the semi-transparent top cover 1, and the mounting screws 10 are installed in sequence. Finally, the rear cover housing 14 is fitted with the mounting plate through hole 20 and the mounting screws 10 are used to fix the indicator light to the mounting plate 19. After the power is turned on, the indicator light starts to work, detects the opening and closing status of the locomotive door, and stably and accurately transmits the door status information to the outside world. When it is necessary to maintain or replace the locomotive door indicator light, the indicator light is disassembled through the hidden disassembly port 4 using a frame remover to inspect or replace the internal components.
[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
