Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mine safety indicator lights, and in particular to a mine safety indicator light. Background Technology
[0002] Coal mine gas is one of the important factors affecting coal mine safety during the mining process, therefore, the detection and alarm emergency technology of underground gas concentration is particularly important.
[0003] In addition, the rapid and safe evacuation of workers underground in coal mines during emergency evacuation is also an essential means to achieve safe production in coal mines.
[0004] In existing technologies, most safety exit signs used in coal mines can only produce relatively weak lights, making it difficult to intelligently guide underground workers to safe evacuation directions in the ever-changing underground environment, thus resulting in poor guidance effectiveness. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mine safety indicator light in order to solve the technical problems mentioned in the background.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A mine safety indicator light includes:
[0008] The connecting plate has an access piece and a fixing groove at both ends for connecting two adjacent connecting plates. The side wall of the connecting plate has a sliding groove, and a light-emitting tube is installed inside the sliding groove. An adjustment component is installed inside the sliding groove for adjusting the angle of the light-emitting tube.
[0009] The outer wall of the light tube is provided with several diffused light holes, and the inside of the diffused light holes is provided with a frosted light-transmitting plate.
[0010] Furthermore, spring pins are provided on both sides of one end of the connector.
[0011] Furthermore, the inner sides of the fixing groove are provided with connecting holes that cooperate with the spring pin.
[0012] Furthermore, the adjustment component includes:
[0013] The sliding plate is slidably disposed inside the sliding groove. A connecting shaft is provided at the bottom end of the sliding plate, and a connecting ring is rotatably disposed on the outer peripheral wall of the connecting shaft. The connecting ring is fixedly connected to the cylinder wall of the light-emitting tube.
[0014] Furthermore, the port of the light-emitting tube is inclined to project light onto the ground, and the shape of the light-emitting tube is bent.
[0015] Furthermore, a fixing plate is provided on the back side of the connecting plate, and bolt holes are provided at the four corners of the fixing plate for fixing the connecting plate to the wall.
[0016] In summary, this utility model has at least one of the following beneficial technical effects:
[0017] 1. This mine safety indicator light, because the light-emitting tube is set at an angle, can make contact with the ground, so that an indicator light spot is formed on the road surface of the safety passage. Combined with the light generated by the diffuser hole on the surface of the light-emitting tube, a double warning is formed, which can make workers more intuitive to observe the position of the indicator light and improve the indication effect of the indicator light.
[0018] 2. This mine safety indicator light uses a spring pin that achieves a quick locking function through the elastic deformation of a built-in spring. When the connector is inserted into the fixing slot, the compressed spring pin automatically pops out and engages with the connecting hole, forming a mechanical interlock structure. This ensures a secure connection between the connecting plates, simplifies the installation process, and avoids the inconvenience of using tools in traditional bolt connections.

Detailed Implementation
[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Example:
[0027] Reference Figure 1 - Figure 4 The present invention discloses a mine safety indicator light, comprising:
[0028] A connecting plate 1 is provided with an access piece 2 and a fixing groove 3 at both ends for connecting two adjacent connecting plates 1. A sliding groove 4 is provided on the side wall of the connecting plate 1. A light-emitting tube 5 is provided inside the sliding groove 4. An adjustment component 6 is provided inside the sliding groove 4 for adjusting the angle of the light-emitting tube 5.
[0029] The outer peripheral wall of the light-emitting tube 5 is provided with several light-diffusing holes 7, and the interior of the light-diffusing holes 7 is provided with a frosted light-transmitting plate.
[0030] In this embodiment, several connecting plates 1 are provided and are connected in sequence through the access piece 2 and the fixing groove 3 to form a chain, so that each connecting plate 1 can be bent to adapt to the corners in the mine, so that the indicator light can be bent around the angle of the wall environment, thereby improving the directional accuracy of the indicator light.
[0031] By using the diffused light holes 7 on the surface of the light-emitting tube 5 and the frosted light-transmitting plate, a light source can be generated, enabling workers to accurately judge the position of the indicator lights even in low-brightness environments.
[0032] On the other hand, since the light-emitting tube 5 is set at an angle, the light emitted by the light-emitting tube 5 can come into contact with the ground, so that an indicator light spot is formed on the road surface of the safety passage. The light spot can be adjusted by angle so that the light spot is formed on both sides of the road surface, which can prevent the light spot from being blocked by passing pedestrians. Combined with the light generated by the diffuser hole 7 on the surface of the light-emitting tube 5, a double warning is formed, which can make workers more intuitive to observe the position of the indicator light and improve the indicator effect of the indicator light.
[0033] Specifically, when connecting two connecting plates 1, the spring pins 21 at both ends of the connector 2 are pressed into the inside of the connector 2, and the connector 2 is inserted into the inside of the fixing groove 3. At this time, the spring pins 21 will pop out to the outside and be stuck in the inside of the connecting hole 31. At this time, the purpose of connecting the two connecting plates 1 to each other can be effectively achieved.
[0034] By adjusting the settings of component 6, the angle of the light-emitting tube 5 can be adjusted. Specifically, the sliding plate 61 is slidably set inside the sliding groove 4. The light-emitting tube 5 is rotatably connected to the sliding plate 61 through the connecting shaft 62 and the connecting ring 63. A ratchet assembly is provided between the connecting ring 63 and the connecting shaft 62 to lock the angle of the connecting ring 63 and the connecting shaft 62, so that the angle of the light-emitting tube 5 can be adjusted. At this time, the light-emitting end of the light-emitting tube 5 can shine directly on the ground, thereby forming a light spot on the ground to achieve the purpose of indicating the route.
[0035] The fixing plate 8, which is provided on the back side of the connecting plate 1, is used to fix one of the connecting plates 1 to the wall, and the fixing plate 8 is fixed through the bolt hole 9.
[0036] In a further preferred embodiment of this utility model, such as Figure 3 As shown, spring pins 21 are provided on both sides of one end of the access component 2.
[0037] In this embodiment, the spring pin 21 achieves a quick locking function through the elastic deformation of the built-in spring. When the connecting piece 2 is inserted into the fixing slot 3, the compressed spring pin 21 automatically pops out and locks into the connecting hole 31, forming a mechanical interlocking structure. This ensures a stable connection between the connecting plates 1, simplifies the installation process, and avoids the inconvenience of traditional bolt connections that require tools.
[0038] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the fixing groove 3 has connecting holes 31 on both sides inside, which cooperate with the spring pin 21.
[0039] In this embodiment, the connecting hole 31 and the spring pin 21 are designed with an interference fit, and the inner wall is provided with a guide slope to guide the spring pin 21 to be accurately engaged. The radial constraint force of the hole wall on the spring pin 21 can withstand the vibration and impact in the mining environment, prevent the connecting plate 1 from accidentally disengaging, and improve the overall reliability of the chain structure.
[0040] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the adjustment component 6 includes:
[0041] The sliding plate 61 is slidably disposed inside the sliding groove 4. A connecting shaft 62 is provided at the bottom end of the sliding plate 61. A connecting ring 63 is rotatably disposed on the outer peripheral wall of the connecting shaft 62. The connecting ring 63 is fixedly connected to the cylinder wall of the light-emitting tube 5.
[0042] In this embodiment, the linear movement of the sliding plate 61 within the sliding groove 4, in conjunction with the rotation mechanism of the connecting shaft 62 / connecting ring 63, enables multi-dimensional angle adjustment of the light-emitting tube 5. The ratchet assembly locks the angle through tooth engagement, allowing light to be precisely projected onto the ground to form a light spot, adapting to the lighting needs of different tunnel heights and turns.
[0043] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the port of the light-emitting tube 5 is inclined and is used to project light onto the ground. The shape of the light-emitting tube 5 is bent.
[0044] In this embodiment, the light-emitting tube 5, with its inclined port design, allows most of the light to shine directly onto the ground to form an indicator light spot. The remaining light is diffused through the diffuser hole 7 and reflected by the frosted plate to form ambient lighting. Furthermore, the bent design allows the light spot to form an arrow shape, improving the indicator effect of the light indicator.
[0045] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a fixing plate 8 is provided on the back side of the connecting plate 1, and bolt holes 9 are provided at the four corners of the fixing plate 8 for fixing the connecting plate 1 to the wall.
[0046] In this embodiment, the plate is rigidly connected to the wall through four bolt holes 9, and the back of the fixing plate 8 is provided with a mesh reinforcing rib, which can disperse vibration stress. Combined with the anti-rust coating, it ensures that the plate will not deform or corrode during long-term use in a humid mine environment.
[0047] The implementation principle of the above embodiment is as follows: the safety indicator light achieves an adaptive layout in the roadway through the connecting plate 1 of the chain connection, wherein the spring pin 21 of the access part 2 and the connecting hole 31 of the fixing groove 3 form a mechanical interlock to ensure the connection is stable;
[0048] The position of the light-emitting tube 5 is adjusted by sliding the sliding plate 61 in the sliding groove 4. It is locked at multiple angles in conjunction with the ratchet mechanism of the connecting shaft 62 and the connecting ring 63, so that the tilted port can directly shine most of the light onto the ground to form an arrow-shaped light spot. At the same time, the frosted light-transmitting plate of the diffuser hole 7 diffuses the remaining light to form the ambient light 14. The bolt holes 9 and the mesh reinforcing rib design of the fixing plate 8 ensure the long-term stability of the device in a humid and vibrating environment.
[0049] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
