Description

Technical Field

[0001] The utility model relates to public lighting equipment, in particular to an adjustable lighting lamp. Background Art

[0002] The existing street lamps are relatively complicated to install due to their large size and mass. Generally, the foundation pit is dug first, the steel cage is placed, and concrete is poured. At the same time, several screws that need to be exposed outside the concrete are fixed on the top of the steel cage. Finally, the lamp pole is lifted and the reserved holes on the bottom flange are inserted into the screws on the top of the steel cage, and then fixed with nuts. However, since the lamp and the lamp pole adopt an integrated structure, and the holes of the flange are already opened at the factory, the position of the street lamp during installation cannot be adjusted according to the immediate position of the steel cage screws. Otherwise, the street lamp may not be in the set position after installation, which will affect the lighting angle and range of the lamp. This puts higher requirements on the positioning and installation of the steel cage, but the actual situation is often that when the street lamp is hoisted into place, it is found that the position of the steel cage screws is deviated, so it is time-consuming and laborious to adjust the position of the steel cage and the concrete block, so that the screws can be smoothly inserted into the holes of the flange at the bottom of the lamp pole.

[0003] At the same time, road lighting equipment has a large design power, so it is particularly important to pay attention to heat dissipation when working in hot weather environments. The existing technology mostly uses metal heat sinks specially matched with LEDs to achieve heat exchange between the internal heat of the lamp and the outside air. However, in actual applications, the applicant found that since the heat sink fins are exposed to the outside world and are generally installed on the top of the lamp for aesthetics, it is easy for debris to accumulate in the gaps between the heat sink fins. In particular, large trees such as French paulownia are often planted in urban greening in northern my country. In addition, the distance between road lamps and plants is relatively close, so every year the leaves, fruit debris or dust of the plants are easily retained in the heat sink fins, resulting in a decrease in the heat dissipation effect of the heat sink fins and causing high-temperature short circuits in the lamps. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable lighting lamp. The utility model has a simple structure and can adjust the position of the lamp during installation, thereby greatly reducing the difficulty of installation and improving the installation efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An adjustable lighting lamp comprises a lamp pole and a bracket, both of which are hollow structures, wherein the two ends of the bracket are respectively connected with an adjustment ring and a mounting ring for buckling the lamp.

[0007] The inner bottom ring surface of the adjusting ring cooperates with the top bearing of the lamp pole, and the inner top ring surface of the adjusting ring cooperates with the top cover bearing. The adjusting ring, the top cover and the top surface of the lamp pole form an adjusting chamber isolated from the outside world. The bottom surface of the top cover and the top surface of the lamp pole are both rotatably provided with a hollow sleeve with a key groove on the inner wall. The two hollow sleeves are respectively fixed with upper and lower driving teeth and adjusting teeth. The inner ring surface of the adjusting ring is provided with a driven tooth block meshing with the adjusting teeth.

[0008] The lamp pole is also provided with a power source, the output end of the power source is transmission-connected with a transmission rod with fixed splines, the transmission rod passes through the top surface of the lamp pole, and the rod body where the splines are located is selectively connected to the adjusting teeth and the driving teeth.

[0009] Preferably, the power source comprises an electric push rod fixed in the hollow structure of the lamp pole, the output end of the electric push rod is connected to a motor, and the output end of the motor is transmission-connected to a transmission rod.

[0010] Preferably, the top surface of the mounting ring is also provided with an annular groove for rotatably assembling the driven gear ring, part of the annular surface of the driven gear ring is exposed to the outside and is provided with fan blades for blowing air to the cooling fins of the lamp, and the driven gear ring is connected to the driving gear through a transmission mechanism.

[0011] Preferably, the transmission mechanism includes two pulleys rotatably arranged in the hollow structure of the bracket and driven by a belt, a driven gear is coaxially connected to the top of the pulley, and the two driven gears are respectively meshed with the driving teeth and the driven gear ring for transmission.

[0012] Preferably, the outer wall of the lamp pole is also assembled with the bottom of the auxiliary pole through a bearing, and the top of the auxiliary pole is connected to the bottom wall of the bracket and cooperates with the lamp pole to form a triangular structure.

[0013] Preferably, the bottom of the hollow sleeve is provided with an inner chamfer.

[0014] The working process of this utility model is as follows:

[0015] When installing street lights, the installation angle of the lamp pole can be adjusted according to the current position of the reserved screw rod of the steel cage. When it is found that there is a deviation between the lamp position and the designed position after installation, the following adjustments can be made: When the street light leaves the factory, the spline part of the transmission rod is set to cooperate with the hollow sleeve of the adjusting tooth, and then the motor is turned on. The transmission of the motor output end-transmission rod-adjusting tooth-driven gear block-adjusting ring-bracket can realize the turnover of the lamp relative to the lamp pole (the adjusting ring and the lamp pole are matched through bearings), thereby adjusting the lighting position of the lamp, and then the motor self-locks to fix the angle of the bracket relative to the lamp pole.

[0016] At the same time, according to environmental changes, municipal staff regularly maintain street lights:

[0017] Turn on the electric push rod, so that it pushes the motor upward, and then the spline part of the transmission rod passes over the adjustment tooth and only fits with the hollow sleeve of the driving tooth, and then turn on the motor to rotate. The transmission of the motor output end-transmission rod-driving tooth-driven gear of the transmission mechanism-driven gear ring can realize the fast turnover of the fan blade driven by the driven gear ring, and then form an airflow beside the cooling fins and blow out the dust in the gap of the cooling fins, the debris of the dry blades and other debris, so as to ensure the heat dissipation effect of the cooling fins. Finally, turn off the motor and reset it.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] 1) The utility model has a simple structure and can adjust the position of the lamp during installation, greatly reducing the difficulty of installation and improving the installation efficiency;

[0020] 2) The utility model can quickly remove impurities from the gaps of the heat dissipation fins exposed to the outside on the top of the lamp according to environmental conditions, thereby ensuring the heat dissipation effect of the heat dissipation fins and the service life of the lamp.

[0021] Figure 1 It is a schematic diagram of the structure of the adjustable lighting lamp in a specific implementation manner. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] like Figure 1 As shown, an adjustable lighting lamp includes a lamp pole 1 and a bracket 2, both of which are hollow structures. The two ends of the bracket 2 are respectively connected with an adjustment ring 21 and a mounting ring 22 for snapping on the lamp 3. The outer wall of the lamp pole 1 is also assembled with the bottom of the auxiliary rod 11 through a bearing. The top of the auxiliary rod 11 is connected to the bottom wall of the bracket 2 and cooperates with the lamp pole 1 to form a triangular structure.

[0024] The inner bottom ring surface of the adjusting ring 21 cooperates with the top bearing of the lamp pole 1, and the inner top ring surface of the adjusting ring 21 cooperates with the bearing of the top cover 15. The adjusting ring 21, the top cover 15 and the top surface of the lamp pole 1 form an adjusting chamber isolated from the outside world. The bottom surface of the top cover 15 and the top surface of the lamp pole 1 are both rotatably provided with a hollow sleeve 4 with a key groove on the inner wall. The bottom of the hollow sleeve 4 is provided with an inner chamfer. The upper and lower driving teeth 42 and the adjusting teeth 41 are respectively fixed on the two hollow sleeves 4. The inner ring surface of the adjusting ring 21 is provided with a driven tooth block 25 meshing with the adjusting teeth 41.

[0025] The top surface of the mounting ring 22 is also provided with an annular groove 26 for rotating and assembling a driven gear ring 43. Part of the annular surface of the driven gear ring 43 is exposed to the outside and is provided with fan blades 44 for blowing air to the heat dissipation fins 31 of the lamp. Two pulleys 23 driven by a belt are rotatably provided in the hollow structure of the bracket 2.

[0026] An electric push rod 12 is provided in the hollow structure of the lamp pole 1, and the output end of the electric push rod 12 is connected to a motor 13. The output end of the motor 13 is connected to a transmission rod 14 with a fixed spline. The transmission rod 14 passes through the top surface of the lamp pole and the rod body where the spline is located is connected to either the adjusting tooth 41 or the driving tooth 42.

[0027] The working process of this utility model is as follows:

[0028] When installing the street lamp, the installation angle of the lamp pole can be adjusted according to the instantaneous position of the reserved screw rod of the steel cage. When it is found that there is a deviation between the position of the lamp and the designed position after the installation is completed, the following adjustments can be made: when the street lamp leaves the factory, the spline part of the transmission rod 14 is set to cooperate with the hollow sleeve 4 of the adjusting tooth 41, and then the motor 13 is turned on to rotate. The transmission of the output end of the motor 13-transmission rod 14-adjusting tooth 41-driven gear block 25-adjusting ring 21-bracket 2 can realize the rotation of the bracket 2 to drive the lamp 3 relative to the lamp pole 1 (the adjusting ring 21 and the lamp pole 1 are matched through bearings), thereby adjusting the lighting position of the lamp 3, and then the motor 13 self-locks to fix the angle of the bracket 2 relative to the lamp pole 1.

[0029] At the same time, according to environmental changes, municipal staff regularly maintain street lights:

[0030] Turn on the electric push rod 12, so that the electric push rod 12 pushes up the motor 13, so that the spline part of the transmission rod 14 passes over the adjustment tooth 41 and is only plugged into the hollow sleeve 4 of the driving tooth 42, and then turn on the motor 13 to rotate. The transmission of the output end of the motor 13-transmission rod 14-driving tooth 42-driven gear 24-driven gear ring 43 can realize the driven gear ring 43 to drive the fan blade 44 to rotate quickly, and then form an airflow beside the cooling fin 31 and blow out the dust, debris of the dry blades and other debris in the gap of the cooling fin 31, so as to ensure the heat dissipation effect of the cooling fin. Finally, turn off the motor and reset it.
