Description

Technical Field

[0001] This utility model belongs to the field of outdoor lighting technology, and more specifically, it relates to a street lamp cover that is easy to disassemble. Background Technology

[0002] Streetlights, as core outdoor lighting facilities, are widely used in municipal roads, parks, and other scenarios, serving both illumination and environmental beautification functions. The streetlight cover is a crucial protective component, protecting the internal light source and electrical components from rain, dust, and other corrosive elements, ensuring stable operation of the streetlight. Most existing streetlight covers are of a split structure, consisting of an upper cover and a lower cover: the upper cover connects to the light pole and houses the internal components, while the lower cover is made of a light-transmitting material to diffuse light. The lower cover is typically secured to the bottom of the upper cover using multiple sets of bolts around its edge.

[0003] Existing application number CN202323256240.1 discloses an energy-saving street lamp cover, relating to the field of lamp cover technology. It includes an upper lamp cover with a rectangular mounting groove at its bottom. A heat dissipation frame is installed inside the mounting groove, and a positioning ring is located above the mounting groove. A stabilizing frame is located inside the heat dissipation frame, and a set of lower lamp covers is installed inside the stabilizing frame. This invention provides a novel upper and lower lamp cover based on a street lamp design, with a heat dissipation frame between them. The heat dissipation frame effectively dissipates heat from the lower lamp cover. The lower lamp cover includes a positioning frame, a positioning sleeve, a heat dissipation block, and a locking buckle. The lower lamp cover, with the locking buckle, achieves convenient assembly and disassembly, solving the problem of current lower lamp covers being fixed with bolts.

[0004] Based on the above, most existing street light covers are of a split structure, with the lower and upper covers secured by multiple sets of bolts. Disassembly and assembly require individual operation, a cumbersome process that inconveniences daily maintenance. In rainy and humid areas, sealing rings or waterproof adhesives are often used at the connection between the cover and the light body to enhance sealing and prevent rainwater infiltration, thus avoiding short circuits or corrosion of internal components due to moisture. However, sealing rings and waterproof adhesives are prone to aging and failure under long-term outdoor environmental erosion, and initial problems are difficult to detect, easily leading to corrosion of electronic components and increasing maintenance costs. Furthermore, waterproof adhesive is often simply applied to the connection points, and it is prone to peeling off after long-term use, further exacerbating sealing risks. Utility Model Content

This addresses the issue that existing street lamp covers are mostly of a split structure, with the lower and upper covers relying on multiple sets of bolts for fixation. Disassembly and assembly require individual bolt operations, a cumbersome process that inconveniences daily maintenance. In rainy and humid areas, sealing rings or waterproof adhesives are often used at the connection between the lamp cover and the lamp body to enhance sealing and prevent rainwater infiltration, thus avoiding short circuits or corrosion of internal components due to moisture. However, sealing rings and waterproof adhesives are prone to aging and failure under long-term outdoor environmental corrosion, and initial problems are difficult to detect, easily leading to corrosion of electronic components and increasing maintenance costs. Furthermore, waterproof adhesives are often simply applied to the connection points, and are prone to peeling off after long-term use, further exacerbating the sealing problems.

[0006] The purpose and function of this utility model, which provides a street lamp cover that is easy to disassemble, are achieved by the following specific technical means: A street lamp cover that is easy to disassemble includes an upper lamp cover, a lower lamp cover, a knob, an observation window, a rotating shaft, a limiting component, and a sealing component. The lower lamp cover is disposed at the bottom of the upper lamp cover. Two sets of knobs are provided, and the two sets of knobs are rotatably connected to both sides of the bottom of the upper lamp cover. The observation window is fixedly connected inside the lower lamp cover. Two sets of rotating shafts are provided, and the two sets of rotating shafts are rotatably connected to both sides of the inside of the upper lamp cover. The limiting component is disposed inside the upper lamp cover. The sealing component is disposed inside the upper lamp cover.

[0007] Furthermore, the limiting component includes: a drive rod and a drive worm gear. The drive rod is provided in two sets, which are rotatably connected to both sides of the bottom of the upper lamp cover, and the two sets of drive rods are respectively fixedly installed on the top of the two sets of knobs; the drive worm gear is provided in two sets, which are respectively fixedly installed on the top of the two sets of drive rods.

[0008] Furthermore, the limiting component also includes: a drive worm gear and a threaded rod. The drive worm gear is provided in two sets, and the two sets of drive worm gears are coaxially and fixedly installed in the middle of the two sets of rotating shafts. The drive worm gear and the drive worm mesh with each other. The threaded rod is provided in four sets, and the four sets of threaded rods are respectively fixedly installed at both ends of the two sets of rotating shafts.

[0009] Furthermore, the limiting component also includes: a connecting frame, a limiting groove, and a limiting hook. The connecting frame is provided in four sets, and the four sets of connecting frames are fixedly installed inside the lower lampshade. The limiting groove is provided in four sets, and the four sets of limiting grooves are respectively opened inside the four sets of connecting frames. The limiting hook is provided in four sets, and the four sets of limiting hooks are slidably connected inside the upper lampshade and threadedly connected to the outside of the four sets of threaded rods.

[0010] Furthermore, the sealing assembly includes: a first sealing groove and a second sealing groove, wherein the first sealing groove is formed at the bottom of the upper lamp cover; the second sealing groove is formed at the bottom of the upper lamp cover and is located outside the first sealing groove.

[0011] Furthermore, the sealing assembly also includes a sealing ring and a sealing groove, wherein the sealing ring is embedded in the top of the lower lamp cover; and the sealing groove is fixedly installed on the outside of the lower lamp cover.

[0012] Furthermore, the sealing assembly also includes a storage cylinder and a mesh plate, wherein the storage cylinder is fixedly installed inside the observation window; and the mesh plate is fixedly installed at one end of the storage cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this invention features a limiting component. A knob drives a drive rod to rotate, causing a drive worm gear to mesh and drive a worm wheel to rotate. This, in turn, drives the rotating shaft and the threaded rods at both ends to rotate synchronously. The threaded rods, through threaded transmission, drive a limiting hook to slide and engage in the limiting groove of the connecting frame, achieving a secure connection between the upper and lower lampshades. Disassembly is simple: just reverse the knob to disengage the limiting hook from the limiting groove via the transmission structure. This eliminates the need to operate multiple sets of bolts individually, significantly simplifying the disassembly and assembly process and improving maintenance efficiency, making it particularly suitable for high-altitude operations.

[0014] Secondly, this invention features a sealing assembly. An initial seal is formed by the sealing ring at the top of the lower lampshade embedding into the first sealing groove of the upper lampshade. Simultaneously, the sealing ring groove and the second sealing groove together form a convex ring groove. After waterproof adhesive is injected, it cures to form a convex waterproof layer. The convex structure effectively limits the waterproof layer to prevent detachment and reduces the contact area with the external environment through the narrow outer layer, slowing down the aging of the inner layer. The color-changing silica gel inside the storage cylinder absorbs infiltrated moisture and changes color. Maintenance personnel can visually detect seal failure through the observation window, enabling timely maintenance, preventing corrosion of electronic components, and reducing maintenance costs.

[0015] This utility model has the advantages of quick disassembly and assembly, reliable sealing, and convenient maintenance. It solves the problems of cumbersome disassembly and assembly, easy failure of sealing and difficulty in detection of traditional street lamp covers, extends the service life of street lamps and improves the convenience of maintenance.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a street lamp cover that is easy to disassemble, including an upper lamp cover 1, a lower lamp cover 2, a knob 3, an observation window 4, a rotating shaft 303, and a limiting component. The lower lamp cover 2 is located at the bottom of the upper lamp cover 1. Two sets of knobs 3 are provided, and the two sets of knobs 3 are rotatably connected to the two sides of the bottom of the upper lamp cover 1. The observation window 4 is fixedly connected inside the lower lamp cover 2. Two sets of rotating shafts 303 are provided, and the two sets of rotating shafts 303 are rotatably connected to the two sides inside the upper lamp cover 1. The limiting component is located inside the upper lamp cover 1.

[0025] The limiting component includes a drive rod 301 and a drive worm gear 302. Two sets of drive rods 301 are provided, and the two sets of drive rods 301 are rotatably connected to the bottom sides of the upper lamp cover 1. The two sets of drive rods 301 are respectively fixedly installed on the top of the two sets of knobs 3. Two sets of drive worm gears 302 are provided, and the two sets of drive worm gears 302 are respectively fixedly installed on the top of the two sets of drive rods 301.

[0026] The limiting assembly also includes: a drive worm gear 304 and a threaded rod 305. There are two sets of drive worm gears 304, which are coaxially fixedly installed in the middle of two sets of rotating shafts 303. The drive worm gears 304 and the drive worm (302) mesh with each other. There are four sets of threaded rods 305, which are fixedly installed at both ends of the two sets of rotating shafts 303 respectively.

[0027] The limiting component also includes: a connecting frame 203, a limiting groove 204, and a limiting hook 306. The connecting frame 203 is provided in four sets, and the four sets of connecting frames 203 are fixedly installed inside the lower lamp cover 2. The limiting groove 204 is provided in four sets, and the four sets of limiting grooves 204 are respectively opened inside the four sets of connecting frames 203. The limiting hook 306 is provided in four sets, and the four sets of limiting hooks 306 are slidably connected inside the upper lamp cover 1. The four sets of limiting hooks 306 are threadedly connected to the outside of the four sets of threaded rods 305.

[0028] The specific usage and function of this embodiment are as follows: During installation, align the bottom of the lower lampshade 2 with the bottom of the upper lampshade 1 and engage, ensuring that the four sets of connecting brackets 203 inside the lower lampshade 2 precisely extend into the upper lampshade 1. Then, use a screwdriver or similar tool to rotate the knobs 3 on both sides. The rotation of the knobs 3 drives the top drive rod 301 to rotate synchronously, causing the drive worm gear 302 to engage with the drive worm wheel 304, which in turn causes the rotating shaft 303 and the threaded rods 305 at both ends to rotate synchronously. The threaded rods 305, through threaded transmission, drive the limiting hooks 306 to slide smoothly inside the upper lampshade 1, ultimately ensuring that the four sets of limiting hooks 306 precisely engage with the limiting grooves 204 of the corresponding connecting brackets 203, achieving a stable and secure connection between the upper lampshade 1 and the lower lampshade 2.

[0029] During disassembly and maintenance, simply rotate the two sets of knobs 3 in the opposite direction to drive the limit hook 306 out of the limit groove 204 through the above-mentioned transmission structure, and easily complete the disassembly of the lower lamp cover 2.

[0030] Example 2: Based on Example 1, as follows Figures 1 to 6 As shown, it also includes a sealing assembly, which is disposed inside the upper lampshade 1.

[0031] The sealing assembly includes a first sealing groove 101 and a second sealing groove 102. The first sealing groove 101 is formed at the bottom of the upper lamp cover 1, and the second sealing groove 102 is formed at the bottom of the upper lamp cover 1, and the second sealing groove 102 is located outside the first sealing groove 101.

[0032] The sealing assembly also includes a sealing ring 201 and a sealing ring groove 202. The sealing ring 201 is embedded in the top of the lower lamp cover 2, and the sealing ring groove 202 is fixedly installed on the outside of the lower lamp cover 2.

[0033] The sealing assembly also includes a storage cylinder 401 and a mesh plate 402. The storage cylinder 401 is fixedly installed inside the observation window 4, and the mesh plate 402 is fixedly installed at one end of the storage cylinder 401.

[0034] The specific usage and function of this embodiment are as follows: When the lower lampshade 2 and the lower lampshade 1 are engaged at the bottom, the sealing ring 201 at the top of the lower lampshade 2 simultaneously embeds into the first sealing groove 101, forming an initial seal and structural positioning. At the same time, the sealing ring groove 202 on the outer side of the lower lampshade 2 precisely aligns with the second sealing groove 102 at the bottom of the upper lampshade 1, forming a convex annular groove that is narrower on the outside and wider on the inside. After waterproof adhesive is injected into this annular groove, it cures to form a convex waterproof layer that fits the groove. The convex structure effectively positions the waterproof layer to prevent it from falling off, and the narrow outer portion reduces the contact area with the external environment, slowing down the aging rate of the inner waterproof layer.

[0035] The storage cylinder 401 inside the observation window 4 is filled with color-changing silicone, and the mesh plate 402 ensures air circulation. When the sealing ring 201 and the waterproof layer age and fail, and moisture seeps into the lower lamp cover 2, the color-changing silicone will preferentially absorb the moisture and change color. Maintenance personnel can visually observe the color change through the observation window 4, quickly determine the sealing failure, and carry out maintenance work in a timely manner, improving the efficiency of troubleshooting.
