Description

Technical Field

[0001] This utility model relates to the field of waterproof street lights, and in particular to a modular outdoor waterproof street light. Background Technology

[0002] To maintain their waterproof performance, waterproof streetlights mostly require the use of sealing rings. These sealing rings are a key component in achieving waterproofing and play an irreplaceable role in the waterproof structure. The lamp body is assembled from multiple parts (such as the lamp housing, lamp shade, base, and junction box), and there are inevitably tiny gaps at the joints between these parts. Sealing rings, typically made of aging-resistant and highly elastic materials (such as silicone or EPDM rubber), are compressed within these gaps, tightly fitting the contact surfaces and completely sealing the gaps. This prevents rainwater, dew, and moisture from seeping into the interior, avoiding short circuits and damage to the internal circuitry and light source due to water ingress.

[0003] Existing modular streetlights are exposed to wind, sun, temperature changes, and vibration for extended periods. The sealing rings may experience gap changes due to thermal expansion and contraction or slight displacement, and are prone to aging, failing to maintain sealing pressure and thus affecting waterproofing stability. Therefore, regular inspection and replacement of the sealing rings are necessary during long-term use. Currently, the streetlight housing and the LED panel used for lighting are mostly fixed with screws. Replacing the sealing ring usually requires disassembling the lighting panel first. However, even after disassembly, workers must hold the panel until the sealing ring replacement is complete before reinstalling it, making the operation difficult and time-consuming. Utility Model Content

[0004] To address the aforementioned issues, this application provides a modular outdoor waterproof street light.

[0005] To achieve the above objectives, this application provides the following technical solution: a modular outdoor waterproof street light, comprising a housing and two light-emitting panels embedded in the lower surface of the housing, wherein two sealing rings are fixed on the lower surface of the housing, the sealing rings are distributed at the edges of the light-emitting panels, and positioning hoops are fixed on each light-emitting panel, the positioning hoops extending beyond the sealing rings to the top of the housing.

[0006] The housing has two sets of limiting rods distributed from front to back on the top, and two sets of positioning sleeves distributed from front to back are fixed on the upper surface of the housing. The positioning sleeves are provided with channels on the part of the housing located above, and through holes are opened in the channels. The limiting rods pass through the through holes and are inserted into the inside of the positioning sleeves.

[0007] Each limiting rod has a pressure sleeve fixed at its top. Each pressure sleeve is fixed by two symmetrically distributed pressure ribs. The pressure ribs are all arc-shaped and a limiting unit is provided above the pressure ribs.

[0008] Furthermore, the limiting unit includes two positioning frames fixed to the upper surface of the housing. Each positioning frame is located above two pressure sleeves on the same side. Vertically distributed extension rods are fixed on the upper surface of each pressure sleeve. When the limiting rod passes through the through hole provided in the channel and is inserted into the inner side of the positioning sleeve, the extension rod passes through the positioning frame and extends above it.

[0009] Furthermore, each of the positioning frames is provided with two pressure springs on its inner side. Each pressure spring has a pressure plate fixed at its upper and lower ends. The upper pressure plate is fixed to the positioning frame. When the extension rod passes through the positioning frame and extends to its upper part, the two pressure plates and the pressure spring are coaxially distributed with the extension rod, and the lower pressure plate abuts against the surface of the pressure sleeve.

[0010] Furthermore, multiple vertically distributed guide posts are fixed on the upper surface of the housing. The guide posts are adapted to the channel. When the limiting rod passes through the through hole provided on the channel and is inserted into the inner side of the positioning sleeve, the guide post is located at the end of the channel.

[0011] Furthermore, multiple equally spaced extension supports are fixed on both sides of the positioning frame. Each extension support has a C-shaped structure, and the bottom end of each extension support is fixed to the housing via positioning feet.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] In the process of disassembling the light-emitting panel, this invention allows the panel to be moved laterally away from its original installation position, leaving space for the removable sealing ring. The sealing ring can then be disassembled. Even after the light-emitting panel is moved away from its original installation position, the connection between the panel and the housing remains intact, preventing the panel from falling off. This facilitates timely and quick replacement of the sealing ring, eliminating the need to hold the panel for extended periods during replacement, thus reducing operational difficulty and improving efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figure 1-4 The modular outdoor waterproof street light shown includes a housing 1 and two light-emitting panels 2 embedded in the lower surface of the housing 1. Two sealing rings 3 are fixed to the lower surface of the housing 1, and the sealing rings 3 are distributed at the edges of the light-emitting panels 2. Each light-emitting panel 2 is fixed with a positioning hoop 4, which extends beyond the sealing rings 3 and above the housing 1. The positioning hoop 4 is provided so that the operating point for fixing the light-emitting panels 2 is located above the housing 1.

[0024] Furthermore, two sets of limiting rods 5 distributed from front to back are provided on the upper part of the housing 1, and two sets of positioning sleeves 13 distributed from front to back are fixed on the upper surface of the housing 1. The positioning clamps 4 located on the upper part of the housing 1 are provided with channels, and through holes are opened in the channels. The limiting rods 5 pass through the through holes and are inserted into the inside of the positioning sleeves 13. Therefore, during the disassembly of the light-emitting panel 2, the limiting rods 5 located on the upper part of the light-emitting panel 2 can be operated. After the limiting rods 5 are disengaged from the through holes and the positioning sleeves 13, the positioning clamps 4 can be moved, so that the light-emitting panel 2 moves laterally away from the original installation position, leaving space for the removable sealing ring 3. Subsequently, the sealing ring 3 can be disassembled.

[0025] After the light-emitting panel 2 is moved away from its original installation position, the positioning clamp 4 can still maintain the connection between the light-emitting panel 2 and the housing 1, preventing the light-emitting panel 2 from falling off. This allows for timely and quick replacement of the sealing ring 3, eliminating the need to hold the light-emitting panel 2 for an extended period during the replacement process, reducing operational difficulty and improving the efficiency of the replacement operation.

[0026] Specifically, during the replacement of the sealing ring 3, in order to simultaneously control the movement of the two sets of limiting rods 5 away from the through hole and the positioning sleeve 13, in this utility model, each limiting rod 5 has a pressure sleeve 6 fixed at its top. Each pressure sleeve 6 is fixed by two symmetrically distributed pressure ribs 7. The pressure ribs 7 are all arc-shaped, which can improve their structural strength, prevent deformation under external impact, and extend their service life. Furthermore, it allows the front and rear sets of pressure ribs 7 to approach each other, facilitating simultaneous upward movement of both sets of pressure ribs 7 to release the connection between the limiting rod 5 and the through hole and the positioning sleeve 13, thus enabling the transfer of the light-emitting panel 2. To maintain the stability of the pressure ribs 7, a limiting unit is provided above the pressure ribs 7 in this utility model.

[0027] Specifically, such as Figure 5-6 As shown, the limiting unit includes two positioning frames 9 fixed to the upper surface of the housing 1. Each positioning frame 9 is located above two pressure sleeves 6 on the same side. Vertically distributed extension rods 8 are fixed to the upper surface of each pressure sleeve 6. When the limiting rod 5 passes through the through hole in the channel and is inserted into the inside of the positioning sleeve 13, the extension rod 8 passes through the positioning frame 9 and extends above it. The combination of the positioning frame 9 and the extension rod 8 can limit the upward movement distance of the pressure sleeve 6 and the pressure rib 7, preventing the pressure sleeve 6 and the pressure rib 7 from falling off.

[0028] like Figure 6 As shown, two pressure springs 11 are provided on the inner side of the positioning frame 9. Pressure plates 12 are fixed to the upper and lower ends of each pressure spring 11. The upper pressure plate 12 is fixed to the positioning frame 9. When the extension rod 8 passes through the positioning frame 9 and extends above it, the two pressure plates 12 and the pressure springs 11 are coaxially distributed with the extension rod 8, and the lower pressure plate 12 abuts against the surface of the pressure sleeve 6. The combination of the pressure springs 11 and the two pressure plates 12 improves the tightness of the pressure sleeve 6 in contact with the positioning clamp 4, and further improves the tightness of the limit rod 5 in the insertion state of the through hole and the positioning sleeve 13. Under non-human-controlled conditions, the pressure sleeve 6 and the limit rod 5 are less likely to move upwards and disengage from the through hole and the positioning sleeve 13.

[0029] like Figure 5As shown, multiple vertically distributed guide posts 14 are fixed on the upper surface of the housing 1. The guide posts 14 are adapted to the channel. When the limiting rod 5 passes through the through hole in the channel and is inserted into the inner side of the positioning sleeve 13, the guide posts 14 are located at the end of the channel. During the disassembly of the light-emitting panel 2, the movement path of the positioning hoop 4 and the light-emitting panel 2 can be restricted based on the setting of the guide posts 14, so that the positioning hoop 4 and the light-emitting panel 2 can be moved back after the sealing ring 3 is installed, thus improving the portability during the installation process.

[0030] like Figure 6 As shown, to improve the stability of the positioning frame 9, multiple equidistant extension supports 15 are fixed on both sides of the positioning frame 9. Each extension support 15 has a C-shaped structure, and its bottom end is fixed to the housing 1 via positioning feet 16. Based on the extension supports 15, multiple equidistant arched structures can be formed on both sides of the positioning frame 9, connecting the two sides of the positioning frame 9 to the upper surface of the housing 1. When the positioning frame 9 is subjected to external impact, deformation of the positioning frame 9 is prevented, improving the structural strength of the positioning frame 9 and further extending its service life.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
