Description

Technical Field

[0001] This utility model belongs to the technical field of road lighting equipment, specifically relating to a lamp holder structure that is easy to install. Background Technology

[0002] Streetlights, as a type of urban public facility, play a vital role in urban traffic and the lives of citizens. The base of a streetlight, as the main supporting component, is crucial for its installation and fixation. Current technology typically imposes strict requirements on the flatness of the foundation surface when installing streetlight bases. In actual installation, significant manpower and time are required to clean the foundation surface of debris, dust, and oil stains to ensure a tight bond between the base and the foundation, thereby guaranteeing the stability and safety of the streetlight. However, in real-world urban construction and renovation scenarios, ground conditions are often complex, making it difficult to guarantee an absolutely flat and clean foundation surface. Even after simple cleaning, minor bumps or small stones may remain, affecting the installation result. These stringent installation conditions not only increase the difficulty of installation but also extend the construction period, impacting the overall progress of the streetlight installation project. Especially in areas requiring rapid replacement or addition of streetlights, traditional base installation methods struggle to meet the demands of efficient construction.

[0003] To address the need for easy installation, Chinese utility model patent CN118856255A, "A Streetlight Base for Convenient Installation," proposes a base structure that prevents the lamp post from tipping over. However, it primarily focuses on the connection between the streetlight base and the lamp post, failing to address the issue of instability when the base contacts uneven ground with slight protrusions. Furthermore, its structure is relatively complex and costly. Therefore, there is an urgent need to develop a lamp base structure that is easy to install and can easily conform to the ground during installation. This is of significant practical importance for improving streetlight installation efficiency, reducing costs, and better serving urban construction and citizens' lives. Utility Model Content

[0004] The purpose of this utility model is to provide a lamp holder structure that is easy to install. By using blind holes and grooves on the lower end face of the support to accommodate various small protrusions, the problem of street lamp bases needing to be pre-treated on uneven ground is solved. Otherwise, the lamp post may tilt or fall after installation. Moreover, there is no need to distinguish the installation direction, making the operation simple. In addition, the base structure is simple and the parts of the mass production mold are highly compatible, which can reduce mass production costs.

[0005] Another objective of this invention is to address the risk of electric leakage in street light bases in humid environments. The street light base is made of non-conductive PVC material as a protective measure. Furthermore, blind hole grooves, annular protrusions, and grooves are provided on the lower end surface of the street light base. This forces the leakage current to bypass the wall of the blind hole groove, increasing the creepage distance of the current on the surface of the base and reducing the leakage current to a relatively safe threshold.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lamp holder structure that is easy to install, comprising a lamp holder body, which is an integrally formed, centrally symmetrical structure. The lower end has a support portion, the upper end has a mounting portion, and a through hole is provided in the middle. An annular trapezoidal platform is provided at the bottom of the through hole. Multiple rings of blind hole grooves are arranged in annular array around the lower end face of the lamp holder body. The blind hole grooves are of equal width and are evenly divided into eight equal parts along the circumference. The centrally symmetrical structure enables the lamp holder to achieve uniform force distribution when subjected to external stresses, such as wind loads, avoiding material fatigue caused by localized stress concentration. The through hole in the middle provides good guidance and support for the streetlight pole, ensuring the stability of the streetlight pole in the vertical direction. The annular trapezoidal platform prevents the lamp pole from directly contacting the ground, using physical isolation to block corrosion sources from damaging the lamp pole. When small stones or other minor protrusions are present below the mounting base, the blind groove area above the protrusion undergoes localized plastic deformation to accommodate it, filling irregular spaces on the ground. This ensures effective contact between the base and the ground, preventing unevenness caused by protrusions and reducing the requirement for ground flatness. The base can be placed stably without extensive pre-treatment of the ground. Bolts ensure stable contact with the ground regardless of its angle. Furthermore, the symmetrical eight-part structure eliminates the need for installers to spend time identifying and adjusting the base's orientation, greatly simplifying the installation process, reducing difficulty, and improving efficiency.

[0007] Preferably, the lamp post contacts the through hole and the annular platform via adhesive or threaded connection. By increasing the contact area between the base and the lamp post, the resistance to loosening between the base and the lamp post is increased. At the same time, it avoids direct contact between the base and the ground, which could lead to corrosion of the lamp post or deformation or damage due to freezing in rain or snow, causing the street light to tip over and creating a safety hazard.

[0008] Preferably, the support part is disc-shaped and the mounting part is cylindrical, with the two parts coaxially arranged. The coaxial circular structure enables the lamp holder to achieve uniform force distribution when subjected to external stresses such as wind loads and mechanical vibrations, avoiding material fatigue caused by local stress concentration, thereby enhancing the overall structural strength of the base.

[0009] Preferably, an annular protrusion is provided at the intersection of the lower end face and the through hole. This can, to a certain extent, prevent surface water and dust and other impurities from entering the gap between the base and the ground, protecting the internal structure and connecting parts of the base from corrosion and damage, and extending the service life of the base.

[0010] Preferably, the annular protrusion has several equally spaced annular grooves. This increases the friction and adhesion between the base and the ground, allowing it to better adapt to different types of ground surfaces.

[0011] Preferably, a reinforcing ring with a triangular cross-section is provided between the upper end face of the support and the mounting part. This enhances the overall strength of the connection between the support and the mounting part, thereby reducing stress concentration problems.

[0012] Preferably, the reinforcing ring has four radial reinforcing ribs. These ribs evenly distribute the load to the lower support and improve the load-bearing capacity around the mounting area.

[0013] Preferably, four mounting through holes are provided between the blind hole slots for fixing to the ground.

[0014] Preferably, the support unit is fixed to the ground with bolts through mounting holes, and the mounting unit is fixed to the lamp post with industrial adhesive through through holes. This assembly method is simple, easy to operate, and reduces labor costs and reliance on professional installation teams.

[0015] Preferably, the main body of the lamp holder is made of PVC. PVC base is lightweight, easier to install, and does not require anti-corrosion or anti-leakage treatment. It also eliminates the risk of rust and loosening, and damaged modules can be directly replaced, resulting in low maintenance costs.

[0016] The beneficial effects of this utility model are:

[0017] By setting multiple rings of blind hole grooves distributed in an array on the bottom surface of the lamp holder with a centrally symmetrical structure, it can better fit with the unevenness of the ground while ensuring that the mechanical performance requirements are met, filling the irregular space of the ground, so that the base can be placed stably on the ground without the need for large-scale pretreatment of the ground.

[0018] Meanwhile, the evenly distributed blind hole groove structure eliminates the need for installers to spend time identifying and adjusting the installation direction of the base, greatly simplifying the installation process, reducing installation difficulty, and improving installation efficiency.

[0019] By using a one-piece molding process to produce the base, the blind hole slot design can save materials and reduce production costs.

[0020] The centrally symmetrical structure of the base can reduce the development cost of production molds. At the same time, by adopting modular production molds with high compatibility, mold wear can be reduced. When a mold is damaged, only the damaged part can be replaced instead of the entire mold.

[0021] The blind hole groove and annular groove structure set on the lower end face of the base can increase the surface leakage path length of the street light base, thereby reducing the leakage current on the surface of the street light base and making it safer. Attached Figure Description

[0028] like Figures 1 to 3 As shown, an easy-to-install lamp holder structure includes a PVC lamp holder body. In the design of street light bases, material selection considers conductivity and electrical safety. For example, aluminum alloys and cast iron are conductive, requiring additional insulating coatings and grounding protection to prevent leakage. Damage to the coating or electrolytic corrosion in humid environments can lead to electric shock. Concrete is also conductive when damp, necessitating pre-embedded insulating sleeves to isolate cables, and the reinforcing mesh must be grounded separately; otherwise, grounding leakage can occur due to moisture penetration, and grounding failure after the reinforcing steel corrodes also poses a safety hazard. In these situations, plastic bases, such as those made of PVC, offer a significant safety advantage in humid, salt-spray environments like coastal roads. Their inherent insulation eliminates the need for additional insulation treatment and a grounding system, simplifying the base structure.

[0029] From the perspective of installation characteristics and maintenance needs, metal bases require high installation precision, bolts need regular tightening to prevent rust and loosening, grounding systems require annual inspections, and anti-corrosion treatment is necessary. Concrete bases require pouring, curing, and installation; crack repair is complex, and maintenance of underground pipelines requires demolition and reconstruction, resulting in high costs. PVC plastic bases, on the other hand, are lightweight, easier to install, require no anti-corrosion treatment, have no risk of rust or loosening, and can be directly replaced with a damaged module, resulting in low maintenance costs. Furthermore, considering the total life-cycle cost of the product, plastic bases have a significant cost advantage in mass production due to their low material, installation, and maintenance costs, with higher costs only during mold investment. Therefore, PVC bases have an overwhelming advantage in high insulation requirements such as in humid areas, scenarios requiring frequent maintenance such as urban roads, and reusable temporary lighting such as construction sites. Although PVC materials have a lower strength compared to metal and concrete, this shortcoming can be effectively compensated for through structural design optimization.

[0030] like Figure 1 and Figure 2 As shown, the PVC lamp holder body is a one-piece, centrally symmetrical structure. It has a support part 1 at the lower end and a mounting part 2 at the upper end. The support part 1 is disc-shaped, and the mounting part 2 is cylindrical. The support part 1 and the mounting part 2 are coaxially arranged, with a through hole 3 in the middle. A reinforcing ring 4 with a triangular cross-section is located at the intersection of the upper end face 12 of the support part 1 and the mounting part 2. Several radial reinforcing ribs 5 are provided outside the reinforcing ring 4. Mounting through holes 114 are spaced apart between the reinforcing ribs 5. Bolts are used to fix the support part 1 to the ground through the mounting through holes 114.

[0031] The centrally symmetrical circular base offers significant advantages in streetlight fixture design. From an aesthetic perspective, the circular base boasts a simple and streamlined appearance, blending seamlessly with its surroundings and enhancing the overall beauty of the streetlight. In terms of structural strength and stability, the circular, centrally symmetrical structure ensures a uniform force distribution when subjected to external stresses such as wind loads and mechanical vibrations, preventing material fatigue caused by localized stress concentration and thus strengthening the overall structure of the base. In outdoor streetlight applications, this design significantly improves the equipment's wind resistance in harsh weather conditions, distributing loads from the pole—such as wind loads, its own weight, and accidental impacts—more evenly across the base and the ground. This reduces the risk of tilting or damage caused by wind. Simultaneously, it prevents excessive stress concentration in any small area of ​​the plastic base, greatly reducing the risk of cracking or deformation due to stress concentration. Furthermore, the absence of sharp edges in the circular base reduces the risk of injury in the event of accidental collisions or contact, making it safer. In terms of ease of installation, the circular base has relatively low requirements for the installation location due to its symmetry, and can adapt more flexibly to different installation environments, reducing the adjustment work during the installation process.

[0032] Since the support part 1 is installed on the ground, its bottom area is relatively large compared to the lamp post, which can increase the bending moment arm of the base, enhancing the stability and anti-overturning ability of the base. When wind load acts on the top of the lamp post, the bolts installed in the mounting through holes 114 of the support part 1 bear the tensile force, and the bottom structure of the support part 1 bears the compressive force, forming a force couple to resist overturning. This design can effectively prevent the street light from tilting or falling under strong winds or other external forces. The support part 1 has a larger contact area with the ground compared to the mounting part 2, which can also disperse the foundation compressive stress of the lamp post on the ground, avoid local crushing of the ground caused by the force on the bottom of the lamp base, reduce the risk of ground settlement or deformation due to excessive pressure, and extend the service life of the street light foundation. At the same time, the larger area of ​​the support part 1 is designed to address the structural characteristic of the low tensile strength of the PVC material base. By increasing the area of ​​the support part 1, the bolt tension can be distributed to more points, reducing the force on a single bolt, thereby increasing the tensile strength of the plastic base by increasing the number of bolts.

[0033] The cylindrical structure of mounting part 2 provides good guidance and support for the streetlight pole, ensuring its vertical stability. This design helps reduce pole swaying caused by uneven ground or external forces, and the cylindrical structure exhibits good mechanical properties when subjected to bending loads. Mounting part 2 and the plastic light pole can be D63, D75, or D110, with a wall thickness of 4.5–10 mm, and the pole length can be 50 cm–6 m.

[0034] The reinforcing ring 4, directly connecting the support part 1 and the mounting part 2, serves as a transition area, further enhancing the overall strength of the connection between the support part 1 and the mounting part 2 to reduce stress concentration. Combined with the radially arranged reinforcing ribs 5 evenly distributed around the reinforcing ring 4, the load is evenly transferred to the lower support part 1, preventing cracking at the connection between the plastic base support part 1 and the mounting part 2 due to excessive local stress, and improving the load-bearing capacity around the mounting part 2. The combined arrangement of the reinforcing ribs 5 and the reinforcing ring 4 significantly improves the load-bearing capacity of the base, enabling it to withstand greater weight and external forces. The reinforcing ribs 5 and the reinforcing ring 4 increase the rigidity of the base, making it more stable when bearing the weight of the streetlight pole and external wind loads. Without reducing structural strength, optimizing the design of the reinforcing ribs 5 and the reinforcing ring 4 reduces material usage and production costs. This design makes the base more stable during installation, reducing installation difficulties caused by structural deformation.

[0035] A through hole 3 is provided between the support part 1 and the mounting part 2, and an annular ladder 31 is provided at the bottom of the through hole 3. The lamp post is connected to the mounting part 2 through the through hole 3 and fixed with industrial adhesive. The annular ladder 31 is used to prevent the lamp post from directly contacting the ground, using physical isolation to block corrosion sources from damaging the lamp post. Thus, maintenance only requires replacing the street light base. At the same time, the annular ladder 31 creates a gap between the lamp post and the ground, preventing the bottom of the lamp post from directly contacting surface water and soil moisture, eliminating the risk of corrosion. In cold regions where soil frost heave occurs, the annular ladder 31 can also prevent the lamp post from being directly lifted, protecting the plastic base from shear forces and avoiding safety issues caused by the lamp post being lifted and the street light tilting or falling due to soil frost heave. The annular ladder 31 also increases the anti-loosening ability between the base and the lamp post, increasing the contact area on the bottom surface of the connection between the lamp post and the base, reducing the displacement and loosening of the connecting parts in the central through hole of the base, thereby improving the overall stability of the street light structure and extending its service life.

[0036] An annular protrusion 112 is provided at the intersection of the lower end face 11 of the support part 1 and the through hole 3. Several annular grooves 113 are evenly distributed on the annular protrusion 112. This design detail allows the lamp holder to adapt to various ground conditions. Since different ground conditions may affect the installation of the streetlight base, the design of the annular protrusion 112 and annular grooves 113 increases the friction and adhesion between the base and the ground, enabling it to better adapt to different types of ground, such as concrete, asphalt, and brick. This improves the installation adaptability of the base and reduces installation problems caused by uneven ground or different materials. At the same time, it provides more attachment points, allowing for better fixation when the base is fixed to the ground with expansion bolts, thereby enhancing the connection strength between the streetlight base and the ground. Furthermore, the annular protrusion can, to some extent, prevent surface water and dust from entering the gap between the base and the ground. When rainwater or dust comes into contact with the annular protrusion, it will be blocked, reducing the possibility of moisture and impurities entering the base. This protects the internal structure and connecting parts of the base from corrosion and damage, extending the service life of the base.

[0037] The lower end face 11 of the support part 1 has multiple rings of blind hole grooves 111 arranged in an annular array on its outer periphery. These blind hole grooves 111 are located outside the annular protrusion 112. The blind hole grooves 111 have a uniform thickness, are distributed in a ring shape, and are evenly divided into eight equal parts along the circumference. Several mounting through holes 114 are spaced apart between the blind hole grooves 111. This design significantly improves installation convenience. The ring shape and evenly divided eight parts along the circumference of the blind hole grooves ensure relatively stable contact with the ground regardless of the angle at which the base is placed. Installers do not need to spend time identifying and adjusting the installation direction of the base, greatly simplifying the installation process, reducing installation difficulty, and improving installation efficiency. This is especially important when installing in complex environments or at night. Previously, installing street light bases may have required professional construction personnel and complex measuring tools to ensure installation accuracy. This blind hole groove 111 design makes the installation process more flexible and error-tolerant, allowing even non-professionals to quickly learn how to install it, helping to reduce labor costs and reliance on professional installation teams. Regardless of the installer's skill level, this blind-hole slot design ensures that each base maintains a relatively consistent connection with the ground after installation. This avoids problems such as unstable installation or tilting caused by incorrect installation orientation or improper ground preparation, thus improving the overall quality and reliability of street light installation. The more stable base installation reduces the probability of street light shaking or damage due to installation issues, thereby lowering the frequency and cost of subsequent maintenance. A stable base also extends the lifespan of the street light, providing strong support for the long-term stable operation of urban lighting facilities.

[0038] Meanwhile, the blind slot 111 design reduces the requirements for ground flatness. Due to the presence of the blind slot 111, the contact method between the base and the ground is more flexible. When the ground has a certain degree of unevenness, undulation, or small debris, the blind slot 111 can better fit the uneven areas, filling in irregular spaces and allowing the base to be placed stably on the ground. This eliminates the need for extensive ground pretreatment, such as leveling and cleaning, saving time and costs associated with pre-installation preparation. In special locations where ground leveling is difficult, such as mountain roads, renovations of old neighborhoods, and construction sites, this design ensures stable installation of the streetlight base, broadening the applicability of streetlights and enabling them to function in more complex environments, providing greater flexibility for urban lighting and traffic management.

[0039] The blind hole groove 111 only recesses inward locally on the bottom surface of the base, unlike a through hole groove which completely penetrates the base. This better maintains the integrity and structural strength of the base. When subjected to external impacts or loads, the base can distribute stress more evenly, reducing the risk of damage caused by stress concentration and ensuring the stability of the base during long-term use. The design of the blind hole groove 111 can reduce material usage and save costs to some extent, without affecting its rigidity and load-bearing capacity, and has a relatively small impact on the overall structural strength of the base.

[0040] The assembly process of this utility model embodiment is as follows:

[0041] First, assemble the base and the lamp post 6. Apply a 4-6cm wide layer of industrial glue evenly to the bottom of the PVC lamp post that matches the PVC base. After applying the glue, quickly insert the lamp post 6 into the through hole 3 and insert it all the way in. Then, let the anti-leakage lamp holder sit for more than 3 days to ensure that the bonding is firm. The anti-leakage lamp holder assembly is now complete.

[0042] Before installation, ensure the ground is level and firm. If the ground is soft, it needs to be compacted first; if the ground is sloping, the ground at the installation location needs to be leveled using filler materials such as concrete or mortar.

[0043] When installing the lamp holder, first invert the lamp holder, thread the corresponding wires through the lamp post 6 and the lamp holder, then install the corresponding light fixture at the other end of the lamp post 6. Finally, place the lamp holder vertically in the desired installation position and secure the base with bolts. If the height of the lamp post 6 is 3 meters or more, the base should be fixed at a depth of at least 50cm underground.
