Description

Technical Field

[0001] This utility model belongs to the technical field of injection molded alarm light housing, specifically an edge treatment structure for an injection molded alarm light housing that enhances sealing. Background Technology

[0002] Warning lights, as core warning components in industrial equipment, vehicles, and outdoor facilities, are widely used in mining machinery, chemical production lines, engineering vehicles, and emergency rescue equipment. These scenarios typically involve harsh environments such as high dust levels, strong vibrations, alternating high and low temperatures (-40℃ to 120℃), and liquid spraying (such as rainwater, cleaning water, and chemical waste). This places stringent requirements on the sealing of the warning light housing—it must achieve an IPX6 or higher waterproof rating and an IP54 or higher dustproof rating to prevent external media from intruding and damaging internal core components such as the LED light source, drive circuit, and sensors, ensuring the continuous and reliable operation of the alarm function.

[0003] To achieve high sealing performance, existing technologies often employ a rigid structure of "bolt fastening + sealing ring": an annular groove is opened at the edge of the outer shell splicing (where the upper shell and the lower shell meet), an EPDM or silicone sealing ring is embedded, and then the upper and lower shells are locked together by 4 to 8 bolts evenly distributed along the edge, and the sealing ring is compressed by the bolt preload to form a seal.

[0004] This type of solution has significant drawbacks: ① Disassembly and assembly require tools such as screwdrivers and wrenches, and each unit takes 5-10 minutes to disassemble and assemble, which is difficult to meet the needs of emergency maintenance or frequent relocation; ② After long-term use, the bolts are prone to loosening due to vibration and stripping due to environmental corrosion (such as salt spray), requiring the entire outer shell to be replaced, resulting in high maintenance costs; ③ Uneven bolt distribution can easily lead to insufficient local compression of the sealing ring, forming weak points in the seal, which can easily cause leakage under high-pressure spray or strong vibration scenarios.

[0005] Therefore, this utility model provides an edge treatment structure for an injection-molded alarm light housing that enhances sealing performance. Utility Model Content

[0006] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, an edge treatment structure for injection-molded alarm light housing with enhanced sealing is proposed.

[0008] Preferably, the sealing mechanism includes a fixing ring, a sealing strip ring, and grooves. There are four sets of grooves, which are arranged in a ring on the inner wall of the fixing ring. The fixing ring is movably inserted into the guide plate through the grooves. The top of the inner wall of the fixing ring is fixedly installed with the sealing strip ring. In this design, the cooperation between the fixing ring and the grooves allows the user to quickly insert the lamp cover into its inner wall, thereby providing stable support. After the lamp cover is installed, the sealing strip ring can prevent humid gas from entering the alarm lamp housing through the edge between the lamp cover and the fixing ring.

[0009] Preferably, the clamping mechanism includes a guide rod, a spring, and an arc-shaped block. Several sets of guide rods are provided, and the guide rods are longitudinally slidably installed on both sides of the inner wall of the fixing ring. The springs are fixedly installed on both sides of the inner wall of the fixing ring near the guide rods. The end of the guide rod away from the fixing ring is fixedly installed with the arc-shaped block. In this scheme, the cooperation of the guide rod, spring, and arc-shaped block can achieve the function of clamping the guide plate, so that the guide plate can automatically clamp and fix it after installation to prevent it from falling off. At the same time, when disassembling, the user only needs to pull out the alarm light housing by force.

[0010] Preferably, the fixing component includes a connecting ring and a reinforcing rib. Two sets of connecting rings are provided, and the two sets of connecting rings are fixedly installed on the bottom of the surfaces of the two sets of fixing rings. The top of the connecting ring is fixedly installed with the reinforcing rib, and the reinforcing rib is fixedly installed with the fixing ring. In this solution, the cooperation between the connecting ring and the reinforcing rib can provide stable support for the fixing ring, and can be quickly fixed to the connecting body by bolts, thereby providing stable support for the alarm light housing. Moreover, it can also be spliced ​​and assembled, which can make maintenance and transportation more convenient.

[0011] Preferably, the connecting assembly includes a mating plate and a nut. There are two sets of mating plates, which are fixedly installed on both sides of the top of the connecting ring. The two sets of mating plates are connected to each other by the nuts. In this solution, the mating plates and nuts can be used to connect the two sets of fixing rings and connecting rings to each other, so that they can be spliced ​​into a whole to provide support for the lampshade.

[0012] Preferably, the retaining ring is made of stainless steel. The stainless steel material ensures that the retaining ring will not rust or corrode during long-term use or in humid environments, thus ensuring that corrosion will not affect the sealing of the lamp cover and guaranteeing that the alarm light housing and lamp cover can be used safely and for a long time.

[0013] The beneficial effects of this utility model are as follows:

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 5As shown in the embodiment of this utility model, an edge treatment structure for an injection-molded alarm light housing with enhanced sealing performance includes an alarm light housing 1; a lampshade 2 is fixedly installed at the bottom of the alarm light housing 1, a docking assembly 3 is provided on the surface of the lampshade 2, and a sealing mechanism 4 is provided at the bottom of the lampshade 2; a tightening mechanism 5 is provided in a groove 43 opened in the inner wall of a fixing ring 41, and a fixing assembly 6 is provided at the bottom of the surface of the fixing ring 41; connecting assemblies 7 are provided on both sides of the top of the fixing assembly 6; the docking assembly 3 includes a guide plate 31 and a support plate 32, four sets of guide plates 31 are provided, the four sets of guide plates 31 are fixedly installed in a ring on the surface of the lampshade 2, and the two sides of the guide plates 31 are fixedly installed with the support plate 32; the sealing mechanism 4 includes a fixing ring 41, a sealing strip ring 42, and a groove 43, four sets of grooves 43 are opened in a ring on the inner wall of the fixing ring 41, and the fixing ring 41 is movably inserted into the guide plate 31 through the opening of the groove 43. The top of the inner wall is fixedly installed with the sealing strip ring 42. The clamping mechanism 5 includes a guide rod 51, a spring 52, and an arc block 53. Several sets of guide rods 51 are provided. The several sets of guide rods 51 are longitudinally slidably installed on both sides of the inner wall of the fixing ring 41. The spring 52 is fixedly installed on both sides of the inner wall of the fixing ring 41 near the guide rods 51. The end of the guide rod 51 away from the fixing ring 41 is fixedly installed with the arc block 53. The fixing component 6 includes a connecting ring 61 and a reinforcing rib 62. Two sets of connecting rings 61 are provided. The two sets of connecting rings 61 are fixedly installed on the bottom of the surface of the two sets of fixing rings 41. The top of the connecting ring 61 is fixedly installed with the reinforcing rib 62. The reinforcing rib 62 is fixedly installed with the fixing ring 41. The connecting component 7 includes a mating plate 71 and a nut 72. Two sets of mating plates 71 are provided. The two sets of mating plates 71 are respectively fixedly installed on both sides of the top of the connecting ring 61. The two sets of mating plates 71 are threadedly connected to each other by the nut 72. The fixing ring 41 is made of stainless steel.

[0027] like Figures 1 to 5As shown, the cooperation between the guide plate 31 and the support plate 32 allows the user to quickly and accurately insert the lampshade 2 into the inner wall of the fixing ring 41, thereby preventing loosening and ensuring that the lampshade 2 is installed in the designated position. The cooperation between the fixing ring 41 and the groove 43 allows the user to quickly insert the lampshade 2 into its inner wall, thereby providing stable support. The sealing strip ring 42 can prevent moisture from entering the alarm lamp housing 1 through the edge between the lampshade 2 and the fixing ring 41 after the lampshade 2 is installed. The cooperation between the guide rod 51, the spring 52, and the arc block 53 can achieve the function of pressing the guide plate 31, so that the guide plate 31 can automatically clamp and fix it after installation, preventing it from falling off. At the same time, it can also be disassembled. The user only needs to pull out the alarm light housing 1 with force. The cooperation of the connecting ring 61 and the reinforcing rib 62 can provide stable support for the fixing ring 41. At the same time, it can be quickly fixed to the connecting body by bolts, thus providing stable support for the alarm light housing 1. Moreover, it can also be spliced ​​and assembled, which can make maintenance and transportation more convenient. The cooperation of the docking plate 71 and the nut 72 can dock the two sets of fixing rings 41 and connecting rings 61 together, so that they can be spliced ​​into a whole to provide support for the lamp cover 2. The stainless steel material can prevent the fixing ring 41 from rusting and corroding during long-term use or in humid environments, ensuring that corrosion will not affect the sealing of the lamp cover 2, and ensuring that the alarm light housing 1 and the lamp cover 2 can be used safely and for a long time.

[0028] Working principle: During operation, first place the connecting ring 61 in the usage position. Then, the user picks up another set of connecting rings 61 and aligns them with each other using the mating plate 71. Next, the two sets of mating plates 71 are connected together using the nut 72. Then, the user fixes the connecting ring 61 to the connecting body using bolts. The user then picks up the alarm light housing 1 and aligns the guide plate 31 with the groove 43 on the inner wall of the fixing ring 41. The guide plate 31 is then inserted downwards into the inner wall of the fixing ring 41. When the guide plate 31 is inserted, the support plate 32 will use the arc-shaped block 53 to push the guide rod 51 to both sides, so that... The spring 52 can be compressed and its released elastic force can press against the support plate 32, so that the lamp cover 2 can be stably connected with the fixing ring 41, and then it can be used. During use, the sealing strip ring 42 can prevent moisture from entering the interior of the alarm lamp housing 1 through the edge of the lamp cover 2, thereby preventing fogging. At the same time, when the alarm lamp housing 1 is damaged, since the spring 52 fixes the guide plate 31 only by friction and thrust, the user can directly pull the alarm lamp housing 1 upward, so that the alarm lamp housing 1 can be easily removed for maintenance and repair of the internal electronic components.
