Abstract
Description
Technical Field
[0001] This utility model relates to the field of streetlights, and in particular to a streetlight pole connection device with wind and earthquake resistance. Background Technology
[0002] In areas such as municipal lighting and traffic signal indication, streetlights, as critical infrastructure, are exposed to complex outdoor environments for extended periods, continuously enduring external forces such as wind and vibration. This is especially true in coastal areas where wind speeds are high, posing a more severe challenge to the long-term use of light poles. Currently available light pole connection devices lack sufficient wind and earthquake resistance. They are generally rigidly connected directly to the concrete foundation or use traditional rigid connection brackets. When encountering strong winds or earthquakes, the rigid pole cannot absorb external force energy through reasonable deformation. Instead, the external force is directly transferred to the main body of the light pole and the foundation or connection bracket, causing a sharp increase in stress in that area. When this stress exceeds the material's strength limit, fracture is likely to occur. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a street light pole connection device with wind and earthquake resistance. This connection device has a simple structure, effectively achieves wind and earthquake resistance, and the light pole is less prone to breakage, resulting in a longer service life.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a street light pole connection device with wind and earthquake resistance functions, comprising:
[0005] A connecting base, the upper part of the connecting base has a boss, an upper positioning cylinder is provided on the boss, the lower part of the connecting base has a lower positioning cylinder, the outer wall of the positioning cylinder is provided with multiple interlocking ribs, and the upper positioning cylinder and the lower positioning cylinder are connected to each other;
[0006] A connecting bracket includes a ring of support rods, the top of which extends beyond the upper positioning cylinder. The support rods are arranged in a ring outside the upper positioning cylinder. A support ring is fixed to the top of the support rod. The outer wall of the support ring has a threaded hole and is fixedly connected to the lamp post by screws.
[0007] Furthermore, the support rod is an L-shaped support rod, which is fixed to the connecting base by screws. It has a stepped groove at its top, and the support ring is fixed to the inner wall of the stepped groove and fastened by screws.
[0008] Furthermore, the interlocking ribs are evenly arranged in a ring on the outer wall of the lower positioning cylinder, and include several vertical ribs and a ring rib.
[0009] Furthermore, there are four support rods, and each support rod has an inclined strut on its outer side.
[0010] Furthermore, one end of the diagonal brace is fixed to the connecting base.
[0011] Furthermore, the inner diameter of the upper positioning cylinder and the inner diameter of the supporting ring are matched with the lamp post.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The light pole connection device has a simple structure. After connecting the light pole of the street light, it can quickly transfer the force when the light pole undergoes large deformation, thereby effectively achieving wind and earthquake resistance, and the light pole is not easy to break and has a longer service life.
[0014] 2. When there is strong wind or vibration, the support pole can deform, converting part of the force exerted on it by the light pole into its own bending stress, thereby reducing the wind impact on the light pole. At the same time, the support pole is quick and easy to disassemble and replace.
[0015] 3. Through the action of the interlocking ribs, the connecting base can be more firmly interlocked in the concrete foundation. Under strong winds or strong earthquakes, the connecting base can effectively prevent relative sliding or displacement between the connecting base and the foundation, thus maintaining the stability of the connecting base.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0021] like Figures 1 to 3 The windproof and earthquake-resistant light pole connection device shown includes:
[0022] A connecting base 1, the upper part of the connecting base 1 has a boss 2, an upper positioning cylinder 3 is provided on the boss 2, the lower part of the connecting base 1 has a lower positioning cylinder 4, the outer wall of the positioning cylinder is provided with a plurality of interlocking ribs 5, and the upper positioning cylinder 3 and the lower positioning cylinder 4 are connected to each other.
[0023] A connecting bracket includes a ring of supporting rods. The top of the supporting rods extends beyond the upper positioning cylinder 3. The supporting rods are arranged in a ring outside the upper positioning cylinder 3. A supporting ring 13 is fixed to the top of the supporting rods. The outer wall of the supporting ring 13 has a threaded hole and is fixedly connected to the lamp post 12 by screws 6.
[0024] The process of using this utility model is as follows: First, the concrete foundation 14 is poured. Note that an installation cavity for the connecting base needs to be reserved in the concrete foundation 14. The top of the concrete foundation 14 can be flush with the ground where the street light is installed, or it can protrude relative to the ground. After the concrete is poured and solidified, flowing concrete is poured into the installation cavity. The connecting base 1 is inserted into the installation cavity through the lower positioning cylinder 4. Then, the connecting base 1 is fixedly connected to the grouting sleeve of the solidified concrete foundation with screws. Subsequently, the connecting bracket is fixed on the connecting base 1. After the connecting bracket is connected, the light pole 12 is passed through the support ring 13, the upper positioning cylinder 3, and the lower positioning cylinder 4. The bottom of the light pole passes through the lower positioning cylinder, and its end is submerged in the flowing concrete. Finally, the light pole 12 is tightened through the support ring 13. Since the lower positioning cylinder 4 is provided with multiple interlocking ribs 5, after the concrete foundation is solidified, the connecting base 1 can be interlocked and connected in the concrete foundation, and the bottom of the light pole can also be fixed in the concrete foundation. The connection device for the light pole 12, when connected to the light pole 12, effectively prevents relative sliding or displacement between the connecting base 1 and the concrete foundation when subjected to external forces such as wind and earthquakes. This reduces stress concentration and improves the overall stability of the connection device. The supporting ring 13 evenly distributes the load transmitted from the light pole 12, ensuring balanced stress on each support rod and preventing damage from excessive local stress. Furthermore, the support ring 13 is fixed to the light pole 12 by screws 6, further increasing the connection strength. Additionally, the support rods can deform under strong winds or vibrations, converting some of the wind force into bending stress, thus reducing the wind impact on the light pole 12. After the external force is removed, the support rods release their elastic potential energy, returning to their initial state, ensuring the structural integrity of the connection device and effectively mitigating the impact of external forces on the overall structure of the light pole 12, acting as a buffer and absorbing energy. If the external force reaches the limit of elastic deformation and the support rod undergoes irreversible deformation, the support rod can be directly disassembled and replaced with a new one.
[0025] Furthermore, the support rod is an L-shaped support rod 7, which is fixed to the connecting base 1 by screws 6. Its top has a stepped groove 8, and the support ring 13 is fixed to the inner wall of the stepped groove 8 and secured with screws 6. Specifically, the support rod of this invention is L-shaped, and is fixedly connected to the connecting base 1 by its horizontal bottom portion and screws 6. Simultaneously, the support ring 13 is engaged in the stepped groove 8 of the support rod and secured with screws 6, thereby achieving a quick connection.
[0026] Furthermore, the interlocking ribs 5 are evenly arranged in a ring on the outer wall of the lower positioning cylinder 4, and include several vertical ribs 9 and a ring rib 10. Specifically, in order to make the interlocking ribs 5 and the lower positioning cylinder 4 more tightly fixed, the interlocking ribs 5 are evenly fixed on the outer wall of the lower positioning cylinder 4. At the same time, in order to make the interlocking ribs 5 have interlocking force in the longitudinal direction, the interlocking ribs 5 are also provided with ring ribs 10.
[0027] Furthermore, the number of support rods is four, and each support rod also has a diagonal brace 11 on its outer side. Specifically, in order to increase the strength of the support rod, the present invention also provides a diagonal brace 11 on its outer side. One end of the diagonal brace 11 is fixed to the connecting base 1, and its bottom can be connected to the connecting base by screws. This connection method can ensure that the diagonal brace 11 effectively transmits the external force borne by the support rod to the connecting base 1, and then distributes it to the concrete foundation through the connecting base 1. When the lamp post 12 is subjected to external force, the diagonal brace 11 can guide the force to the connecting base 1 in time, avoiding excessive accumulation of force on the support rod, thereby preventing the support rod from breaking or severely deforming due to excessive force, and reducing the frequency of replacement of the support rod.
[0028] Furthermore, the inner diameter of the upper positioning cylinder 3 and the inner diameter of the supporting ring 13 are matched with the lamp post 12. In this invention, the inner diameter of the upper positioning cylinder 3 matches the lamp post 12. Note that a clearance fit is required. This method provides precise positioning and guidance for the lamp post 12, ensuring that it is accurately installed in the predetermined position during installation, guaranteeing its verticality, and preventing installation deviations from affecting its wind and earthquake resistance. Simultaneously, it allows the lamp post 12 to promptly transfer force to the supporting ring 13 when subjected to wind, preventing large deformation or irreversible breakage of the lamp post 12.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
