Technical Field

[0001] The utility model relates to the technical field of street lamps, in particular to a wind-proof and earthquake-resistant street lamp support structure. Background Technique

[0002] In earthquake-prone areas or typhoon-prone coastal areas, the safety and stability of infrastructure are of crucial importance. Traditional street lamp support structures often do not fully consider the impact of extreme natural conditions during design, resulting in their easy collapse under strong earthquakes or strong winds. This not only causes damage to the street lamps themselves but also may pose a threat to pedestrians, vehicles, and surrounding buildings, thereby leading to casualties and property losses. Especially in the process of urbanization, with the increase in population density and traffic flow, this potential safety hazard becomes more prominent. Therefore, it is particularly urgent to develop a wind-proof and earthquake-resistant street lamp support structure that can effectively resist earthquake shocks and strong wind attacks.

The top of the internally threaded block is connected to the bottom surface of the second support rod. At the top of the second support rod, there is a lamp holder, and the lamp holder is connected to the second support rod through a movable rod.

[0006] Preferably, the base is a conical structure with a narrower top and a wider bottom.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] In order to solve the problem that street lamps in high-incidence areas of strong winds and strong earthquakes in the prior art do not have wind and earthquake resistance functions, the following technical solutions are given. Please refer to Figures 1-4 ;

[0024] An anti-wind and anti-seismic street lamp support structure includes a base 1. A first support rod 2 is provided on the top surface of the base 1. The base 1 is a tapered structure with a narrower upper part and a wider lower part, effectively reducing the overall center of gravity of the street lamp and providing a larger contact area between the first support rod 2 and the ground to prevent the street lamp from tipping over under the influence of strong winds or strong earthquakes.

[0025] The first support rod 2 is a hollow columnar structure. A motor 4 is provided at the bottom of the first support rod 2. A screw rod 5 is also provided inside the first support rod 2. The extending direction of the screw rod 5 is the same as that of the first support rod 2. The output end of the motor 4 is connected to the bottom end of the screw rod 5, and the motor 4 can drive the screw rod 5 to rotate; an internally threaded block 6 penetrates through the screw rod 5. The screw rod 5 cooperates with the internally threaded block 6. The outer diameter of the internally threaded block 6 is equal to the inner diameter of the first support rod 2. A clamping strip for limiting is provided on the internally threaded block 6. The clamping strip cooperates with the card slot on the inner wall of the first support rod 2. The forward and reverse rotation of the screw rod 5 can drive the internally threaded block 6 to rise or fall. The top of the internally threaded block 6 is connected to the bottom surface of the second support rod 7. A channel for the screw rod 5 to penetrate through is provided inside the second support rod 7. The telescopic movement of the second support rod 7 in the first support rod 2 is correspondingly driven by the lifting of the internally threaded block 6.

[0026] A lamp holder 8 is provided at the top of the second support rod 7. The lamp holder 8 is connected to the second support rod 7 through a movable rod 9. An installation groove 10 is opened at the top of the second support rod 7. A rotating shaft 11 is provided in the installation groove 10. The second support rod 7 is rotationally connected to the end of the movable rod 9 through the rotating shaft 11, so that the movable rod 9 can be perpendicular or parallel to the second support rod 7.

[0027] A support seat 3 is provided at the top of the first support rod 2. The support seat 3 and the first support rod 2 are of an integral structure. The inner diameter of the support seat 3 is smaller than the inner diameter of the first support rod 2. The inner diameter of the support seat 3 is equal to the outer diameter of the second support rod 7. The contact area between the first support rod 2 and the second support rod 7 is increased through the support seat 3 to prevent the second support rod 7 from shaking after extending and improve the overall stability.

[0028] A first magnetic block 12 is fixed on the top surface of the movable rod 9. The first magnetic block 12 is provided at one end of the movable rod 9 close to the second support rod 7. A second magnetic block 13 is provided on the side surface of the installation groove 10 opposite to the movable rod 9. The second magnetic block 13 is located on the movement track of the first magnetic block 12. When strong winds or strong earthquakes come, the movable rod 9 is located inside the support seat 3. After the strong winds or strong earthquakes end, the movable rod 9 extends out of the support seat 3. Due to the repulsion between the first magnetic block 12 and the second magnetic block 13, the movable rod 9 and the lamp holder 8 are reset.

[0029] A wedge block 14 is provided at the bottom of the movable rod 9, and the wider end of the wedge block 14 faces the lamp holder 8. When the movable rod 9 retracts into the support base 3, the movement of the movable rod 9 can be made smoother through the wedge block 14.

[0030] Working principle: When strong wind or strong earthquake occurs, the motor 4 is started, and the second support rod 7 is driven to descend and retract into the first support rod 2 through the screw rod 5 and the internal thread block 6. When the movable rod 9 contacts the support base 3, at this time, the second support rod 7 continues to drive the movable rod 9 to move downward. Limited by the support base 3, the movable rod 9 gradually stands upright and retracts into the support base 3 until the lamp holder 8 stands upright on the support base 3, reducing the overall height of the device, decreasing the force-bearing area against the strong wind, and reducing the danger of the device tipping over.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
