Description

Technical Field

[0001] This invention relates to the field of street light installation technology, specifically to a street light adjustment mounting bracket for municipal road lighting projects. Background Technology

[0002] Streetlights, as the most basic lighting facilities for roads, are generally installed symmetrically along both sides of the street. During the installation of streetlights, the installation of the streetlight poles is an important step, playing an indispensable role in the safety of vehicles and pedestrians at night.

[0003] Patent CN111364827A discloses a street light adjustment and installation device for municipal road lighting projects. The device includes two splicing rings, an insert, two rotating groups, a drive motor, a feeding unit, a clamping unit, and gears. The front and rear ends of the two splicing rings are connected by the insert. Each splicing ring has a rotating group inside. The drive motor is mounted on the inner wall of the right-side splicing ring via a base, and a gear is mounted on the output shaft of the drive motor. Feeding units are evenly distributed at the upper end of each splicing ring, and clamping units are mounted at the upper end of each feeding unit. This invention solves the problem that street light installation typically involves manually visually inspecting the verticality of the street light pole and then manually straightening it. This method is too slow for a single pole, and the verticality of the pole straightened by visual inspection often fails to meet installation requirements, potentially leading to collapse and safety hazards after installation.

[0004] In practice, the terrain encountered during the installation of streetlights varies greatly. The aforementioned device can only be installed vertically relative to the ground. Considering that the streetlight would tilt after installation on sloping or other complex terrains, posing a significant safety hazard to pedestrians, and that streetlights should be installed horizontally and vertically to ensure adequate illumination, the aforementioned device can only be installed horizontally relative to the ground, which does not meet the actual installation requirements. Summary of the Invention

[0005] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. Specifically, the purpose of the present invention is to provide a street light adjustment mounting base for municipal road lighting projects to solve the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a street light adjustment mounting base for municipal road lighting projects, comprising a base plate, and further comprising an adjustment mechanism, a leveling mechanism, a clamping mechanism, a limiting mechanism, four fixing blocks, a support plate, a disc, four hinge frames, a mounting box, and a protective cover.

[0007] Preferably, the adjustment mechanism includes four adjusting racks, a first adjusting gear, a second adjusting gear, two rotating components, four first connecting rods, and four second connecting rods. The four adjusting racks are arranged symmetrically in pairs, and two of the adjusting racks are perpendicular to the other two adjusting racks. An L-shaped mounting plate is provided on the top of the base plate. The first adjusting gear is rotatably mounted on the side wall of the L-shaped mounting plate and meshes with two of the adjusting racks. The second adjusting gear is located inside the base plate, and a rotating shaft is provided on one side of the second adjusting gear. The two rotating components are respectively rotatably mounted on the side wall of the first gear and the end of the rotating shaft.

[0008] Preferably, each of the rotating components includes a turntable and a handle, the turntable being rotatably mounted on a rotating shaft, and the handle being fixedly mounted on the side wall of the turntable.

[0009] Preferably, the horizontal mechanism includes a counterweight, a ball head, a spring, a locking pin, and a locking groove. The locking groove is located at the bottom of the disc, the ball head is connected to the bottom of the disc, the ball head has a receiving groove inside, the spring is located in the receiving groove, the locking pin is located on top of the spring, and the locking pin and the locking groove are matched.

[0010] Preferably, the clamping mechanism includes a clamping gear, an upper L-shaped rack, a lower L-shaped rack, a vertical rack, and two U-shaped frames. The vertical rack is disposed at the bottom of the support plate, the clamping gear is rotatably disposed in the cavity, the upper L-shaped rack is disposed above the clamping gear, the lower L-shaped rack is disposed below the clamping gear, and the two U-shaped frames are respectively fixedly disposed at the ends of the upper L-shaped rack and the lower L-shaped rack.

[0011] Preferably, four limiting mechanisms are provided, each of which includes a first limiting block, a second limiting block, a torsion spring, a limiting post, an L-shaped limiting plate, and a limiting rod. The first limiting block is located at one end of the U-shaped frame, the second limiting block is located at the same end of the U-shaped frame, the limiting post is located on the top of the second limiting block, the torsion spring is sleeved on the outer wall of the limiting post, the L-shaped limiting plate is fixedly located on the side wall of the second limiting block, and one end of the limiting rod is rotatably mounted on the limiting post, and the limiting rod is connected to the end of the torsion spring.

[0012] Preferably, a snap-fit ​​groove is provided in the middle of the four fixing blocks.

[0013] Preferably, the base plate is provided with four fixing screws.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The present invention uses a counterweight to drive the ball head and the snap-fit ​​post to always keep them horizontal and vertical. Then, by rotating the rotating assembly, the first adjusting gear is driven to rotate. The rotation of the first adjusting gear drives the two adjusting racks that mesh with it to slide in the same direction. The sliding of the two adjusting racks in the same direction drives the first connecting rods at both ends to move synchronously. The movement of the first connecting rod drives one end of the second connecting rod to move synchronously. The other end of the second connecting rod pulls the corresponding hinge frame to move up and down, and pulls the disc to adjust the tilt angle. It determines whether the snap-fit ​​post is inserted into the slot. This invention realizes that the disc can be adjusted to be horizontal no matter where it is. It is suitable for installation on ground with various tilt angles so that the street light can be kept horizontal and vertical, which meets the actual needs of street light installation.

[0016] (2) In this invention, the support plate moves downward under the gravity of the street lamp, which in turn moves the vertical rack downward. The downward movement of the vertical rack causes the clamping gear to rotate. The rotation of the clamping gear causes the upper L-shaped rack and the lower L-shaped rack to move towards each other, which simultaneously drives the two U-shaped frames to tighten inward. This clamps the four fixing blocks to engage and limit the locking slots. No additional power source is required. The street lamp base can be well fixed by the gravity of the street lamp alone.

[0017] (3) The present invention uses a limiting rod to abut against the fixed slot, so that the limiting rod rotates around the limiting post until the limiting slot is completely engaged between the first limiting block and the second limiting block. When the limiting rod is disengaged from the fixed block, it is ejected by the elastic force of the torsion spring and surrounds the locking groove in the middle of the fixed block. This prevents the street light from shaking and disengaging from the fixed blocks in windy weather, increases the stability of the street light when it is installed at the bottom, further strengthens the installation of the street light, and further enhances the stability of the street light base by installing the street light in the cavity of the mounting box, thus avoiding the street light from tilting or falling over due to severe winds and other weather conditions.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-6An embodiment of the present invention provides a street light adjustment mounting base for municipal road lighting projects, comprising a base plate 4, an adjustment mechanism 7, a horizontal mechanism 2, a clamping mechanism 6, a limiting mechanism 9, four fixing blocks 10, a support plate 8, a disc 11, four hinge frames 12, a mounting box 13, and a protective cover 1. The adjustment mechanism 7 is mounted on the base plate 4, the protective cover 1 is fitted onto the middle of the adjustment mechanism 7, the four hinge frames 12 are hinged to the top of the adjustment mechanism 7, the disc 11 is fixedly mounted in the middle of the four hinge frames 12, the mounting box 13 is fixedly mounted on the top of the disc 11, the mounting box 13 has a cavity inside, the clamping mechanism 6 is mounted in the cavity, the support plate 8 is slidably mounted on the top of the cavity, the four fixing blocks 10 are mounted on the top of the support plate 8, the limiting mechanism 9 is mounted at the end of the clamping mechanism 6, and the ball head 24 of the horizontal mechanism 2 is connected to the bottom of the disc 11. First, place the device at the desired installation location for the streetlight. Then, use the horizontal mechanism 2 to determine if the disc 11 is horizontal and vertical. Next, use the adjustment mechanism 7 to adjust the tilt angle of the disc 11 in conjunction with the hinge frame 12. Use the horizontal mechanism 2 to determine if the disc 11 is level. After leveling the disc 11, place the four fixing blocks 10 corresponding to the mounting holes at the bottom of the streetlight onto the support plate 8. The support plate 8 then moves downward along the cavity under the weight of the streetlight. The downward movement of the support plate 8 causes the clamping mechanism 6 to engage the four fixing blocks 10. At the same time, the limiting mechanism 9 rotates due to the resistance of the fixing blocks 10 until the end of the clamping mechanism 6 is fully engaged with the fixing blocks 10. Then, the limiting mechanism 9 automatically resets after disengaging from the resistance of the fixing blocks 10, thus limiting and engaging the fixing blocks 10. At this point, the bottom of the streetlight is located inside the cavity, and the bottom of the streetlight is engaged and fixed with the fixing blocks 10.

[0027] Specifically, the adjustment mechanism 7 includes four adjusting racks 71, a first adjusting gear 74, a second adjusting gear 73, two rotating components 3, four first connecting rods 72, and four second connecting rods 75. The four adjusting racks 71 are arranged symmetrically in pairs, and two adjusting racks 71 are perpendicular to the other two adjusting racks 71. An L-shaped mounting plate 14 is provided on the top of the base plate 4. The first adjusting gear 74 is rotatably mounted on the side wall of the L-shaped mounting plate 14. The first adjusting gear 74 is meshed above two of the adjusting racks 71. The second adjusting gear 73 is located inside the base plate 4. A rotating shaft 33 is provided on one side of the second adjusting gear 73. The two rotating components 3 are respectively rotatably mounted on the side wall of the first gear and the end of the rotating shaft 33. Rotating the rotating assembly 3 drives the first adjusting gear 74 to rotate. The rotation of the first adjusting gear 74 drives the two adjusting racks 71 meshing with it to slide in the same direction. The sliding of the two adjusting racks 71 in the same direction drives the first connecting rods 72 at both ends to move synchronously. The movement of the first connecting rods 72 drives one end of the second connecting rod 75 to move synchronously. The other end of the second connecting rod 75 pulls the corresponding hinge frame 12 to move up and down, and pulls the disc 11 to adjust the tilt angle.

[0028] Specifically, each of the rotating components 3 includes a turntable 31 and a handle 32. The turntable 31 is rotatably mounted on a rotating shaft 33, and the handle 32 is fixedly mounted on the side wall of the turntable 31. Rotating the handle 32 drives the turntable 31 to rotate.

[0029] Specifically, the horizontal mechanism 2 includes a counterweight 25, a ball head 24, a spring 23, a locking pin 22, and a locking groove 21. The locking groove 21 is located at the bottom of the disc 11, and the ball head 24 is connected to the bottom of the disc 11. The ball head 24 has a receiving groove inside, and the spring 23 is located in the receiving groove. The locking pin 22 is located on top of the spring 23, and the locking pin 22 matches the locking groove 21. The counterweight 25 drives the ball head 24 and the locking pin 22 to remain horizontal and vertical. Then, the locking pin 22 is ejected by the elastic force of the spring 23 and engages with the locking groove 21, thereby realizing the horizontal adjustment of the turntable 31.

[0030] Specifically, the clamping mechanism 6 includes a clamping gear 61, an upper L-shaped rack 63, a lower L-shaped rack 64, a vertical rack, and two U-shaped frames 62. The vertical rack is disposed at the bottom of the support plate 8. The clamping gear 61 is rotatably disposed in the cavity. The upper L-shaped rack 63 is disposed above the clamping gear 61. The lower L-shaped rack 64 is disposed below the clamping gear 61. The two U-shaped frames 62 are respectively fixedly disposed at the ends of the upper L-shaped rack 63 and the lower L-shaped rack 64. The support plate 8 moves downward under the weight of the street light, causing the vertical rack to move downward. The downward movement of the vertical rack causes the clamping gear 61 to rotate. The rotation of the clamping gear 61 causes the upper L-shaped rack 63 and the lower L-shaped rack 64 to move towards each other, simultaneously causing the two U-shaped frames 62 to tighten inward, thus limiting and clamping the four fixing blocks 10. No additional power is required; the street light bottom is limited and clamped by the weight of the road in conjunction with the fixing blocks 10. No manual operation is required, which is convenient, quick, and energy-saving.

[0031] Specifically, four limiting mechanisms 9 are provided. Each limiting mechanism 9 includes a first limiting block 91, a second limiting block 93, a torsion spring 92, a limiting post 95, an L-shaped limiting plate 94, and a limiting rod 96. The first limiting block 91 is located at one end of the U-shaped frame 62, the second limiting block 93 is located at the same end of the U-shaped frame 62, the limiting post 95 is located on the top of the second limiting block 93, the torsion spring 92 is sleeved on the outer wall of the limiting post 95, the L-shaped limiting plate 94 is fixedly located on the side wall of the second limiting block 93, and one end of the limiting rod 96 is rotatably mounted on the limiting post 95. The limiting rod 96 is connected to the end of the torsion spring 92. By abutting the fixing slot 21 with the limiting rod 96, the limiting rod 96 rotates around the limiting post 95 until the limiting slot 21 is fully engaged between the first limiting block 91 and the second limiting block 93. At this point, the limiting rod 96 is ejected from the fixing block 10 by the elastic force of the torsion spring 92, encircling the middle of the fixing block 10 to prevent the street light from swaying and coming off the fixing block 10 in windy weather. This increases the stability of the street light when it is installed at the bottom and further strengthens the installation of the street light.

[0032] Specifically, the four fixing blocks 10 are provided with snap-fit ​​grooves in the middle.

[0033] Specifically, four fixing screws 5 are provided on the base plate 4.

[0034] Working principle: First, place the device at the desired installation location for the street light. Then, fix the base plate 44 with fixing screws 55. Next, determine whether the disc 11 remains horizontal and vertical by checking if the locking pin 22 is inserted into the slot 21. Then, rotate the handle 32 to rotate the disc 31. The rotation of the disc 31 drives the first adjusting gear 74 to rotate. The rotation of the first adjusting gear 74 drives the two adjusting racks 71 meshing with it to slide in the same direction. The sliding of the two adjusting racks 71 in the same direction drives the first connecting rods 72 at both ends to move synchronously. The movement of the first connecting rods 72 drives one end of the second connecting rod 75 to move synchronously. The other end of the second connecting rod 75 pulls the corresponding hinge frame 12 to move up and down, pulling the disc 11 to adjust the tilt angle. The counterweight 25 drives the ball head 24 and the locking pin 22 to remain horizontal and vertical. Then, the locking pin 22 is ejected by the elastic force of the spring 23 and locks into the slot 21, thereby realizing the horizontal adjustment of the disc 31. After leveling 31, the mounting box 13 installed on the turntable 31 is also kept level. Then, the mounting holes at the bottom of the street light, corresponding to the four fixing blocks 10, are placed on the support plate 8. Then, the support plate 8 moves downward under the weight of the street light, causing the vertical rack to move downward. The downward movement of the vertical rack causes the clamping gear 61 to rotate. The rotation of the clamping gear 61 causes the upper L-shaped rack 63 and the lower L-shaped rack 64 to move towards each other, simultaneously causing the two U-shaped frames 62 to tighten inward, thus limiting the position of the four fixing blocks 10. The clamping mechanism simultaneously engages with the fixing slot 21 via the limiting rod 96, causing the limiting rod 96 to rotate around the limiting post 95 until the limiting slot 21 is fully engaged between the first limiting block 91 and the second limiting block 93. At this point, the limiting rod 96 disengages from the fixing block 10 and is ejected by the elastic force of the torsion spring 92, surrounding and limiting the engagement groove in the middle of the fixing block 10. At this time, the bottom of the street light is located in the cavity, and the bottom of the street light is engaged and fixed with the fixing block 10, further increasing the overall stability of the bottom of the street light.

[0035] Although the present invention 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 invention should be included within the protection scope of the present invention.
