Description

Technical Field

[0001] The utility model specifically relates to the technical field of street lamp components, in particular to a solar street lamp cap. Background Art

[0002] Solar street lights are environmentally friendly and energy-saving devices that use solar energy to generate electricity, store electricity and provide street lighting. Compared with traditional grid-connected street lights, solar street lights do not require an external power supply. The lamp heads of adjustable solar street lights on the market are generally connected by pins and fastened with threaded pairs.

[0003] There are two existing ways to connect street lamps to lamp poles. One is to use welding for fixed connection. This connection method is not convenient for replacing the lamp head in subsequent use, and the angle cannot be adjusted.

[0004] Another connection method is to fix the lamp head on the lamp stand through the combination of a U-shaped hoop and a nut. This connection method needs to be used with a rubber pad. However, after a long period of exposure to wind and sun, the rubber pad will oxidize and fall off, causing the U-shaped hoop to loosen the fixation of the lamp head. After multiple strong winds, the connection position of the lamp head will shift, causing the light to shine on other positions, and even the risk of falling off.

[0005] Therefore, re-fixing the lamp holder will consume a lot of manpower and material resources. Utility Model Content

[0006] The utility model aims to provide a solar street lamp holder, which can prevent the connection from loosening by inserting the street lamp pole into the inner side of the end of the lamp post locking connector and then welding the connection. After the locking bolt is removed by a wrench, the lamp holder can be easily disassembled, eliminating the rubber pad at the connection, thereby solving the problem of the connection position of the lamp holder shifting due to oxidation and shedding of the rubber pad.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A solar street lamp head, comprising an adjustable fastener capable of adjusting the tilt direction of the lamp head and locking it firmly

[0009] The adjustable fastener is composed of two parts: a fixed adjuster assembly fixedly connected to the supporting base plate and a lamp post locking connector connected to the street lamp post;

[0010] The bottom of the fixed regulator assembly is arranged in an arc shape, and the arc-shaped bottom is also provided with a limit slide groove capable of preventing the arc-shaped bonding plate from sliding left and right. At the same time, the bottom of the fixed regulator assembly is also connected with a plurality of locking bolts for fixing the arc-shaped bonding plate through threads;

[0011] The upper part of the lamp post locking connector is provided with an arc-shaped fitting plate which is concave and fits with the surface of the limiting slide groove, and the inner side of the arc-shaped fitting plate is provided with adjustable slide grooves which can adjust the lamp head and are symmetrically arranged and run through the front and back;

[0012] The curvature of the bottom of the limiting slide groove is the same as the curvature of the upper part of the arc-shaped fitting plate that can move forward and backward, and the end of the locking bolt passes through the inner side of the adjustable slide groove and is connected with the fixed regulator component.

[0013] As a further technical solution of the utility model, the end of the lamp post locking connector is a hollow inclined fixed sleeve, and the plane end of the limiting slide groove is fixed with a supporting base plate that supports the entire lamp head.

[0014] As a further technical solution of the utility model, the bottom of the supporting base plate is respectively installed with an LED lighting lamp for lighting and a lamp control box for providing stable voltage and current for the LED lighting lamp, and a plurality of LED lighting lamps are provided.

[0015] As a further technical solution of the utility model, a mounting frame is installed on the outer side of the supporting base plate by screws, and the mounting frame consists of four concave metal frames.

[0016] As a further technical solution of the utility model, the supporting base plate is located at the lower inner part of the mounting frame, and a photovoltaic power generation component capable of converting light energy into electrical energy is also fixed to the upper inner part of the mounting frame.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model inserts the street lamp pole into the inner side of the end of the lamp post locking connector, and then welds the connection, which can prevent the connection from loosening. After the locking bolt is removed by a wrench, the lamp holder can be easily disassembled, and the rubber pad at the connection is omitted, thereby solving the problem of the connection position of the lamp holder shifting due to oxidation and shedding of the rubber pad.

[0019] The utility model inserts the street lamp pole into the inner side of the end of the lamp post locking connector, and then uses the bolt to penetrate the connection between the lamp post locking connector and the street lamp pole, which can play a positioning role and prevent the lamp head from moving due to oxidation and shedding of the rubber pad. When replacing the lamp head, the bolt can be removed to realize the rapid replacement of the lamp head.

[0020] The utility model can adjust the inclination angle of the lamp head by loosening the locking bolt and adjusting the relative position of the arc-shaped fitting plate inside the limiting sliding groove, thereby adjusting the irradiation position of the light.

[0036] In this embodiment, the supporting base plate 2 is located at the lower inner portion of the mounting frame 1 , and a photovoltaic power generation component 7 capable of converting light energy into electrical energy is also fixed to the upper inner portion of the mounting frame 1 .

[0037] By adopting the above technical solution, the street light pole is inserted into the inner side of the end of the lamp post locking connector 6 and then welded or connected with bolts. There is no need to install rubber pads at the connection to avoid movement caused by aging of the rubber pads. At the same time, the locking bolts 52 are loosened and the relative position of the arc-shaped fitting plate 61 on the inner side of the limiting slide groove 51 is adjusted. The lamp head can be adjusted, thereby adjusting the irradiation position of the light, and the contact surface between the limiting slide groove 51 and the arc-shaped fitting plate 61 can increase a certain friction force, thereby improving the stability effect after fixation.

First, the locking bolt 52 is loosened, and then the relative position of the arc-shaped fitting plate 61 on the inner side of the limiting slide groove 51 is adjusted. At the same time, the position of the locking bolt 52 on the inner side of the adjustable slide groove 62 also changes accordingly. Then, the locking bolt 52 is tightened. Under the action of the clamping force, the contact surface of the limiting slide groove 51 and the arc-shaped fitting plate 61 fits tightly, increasing the friction force at the contact position, thereby improving the stability after fixation. The solar panel converts light energy into electrical energy and stores it on the inner side of the battery. Then, under the action of the lighting lamp driving circuit board, a stable current and voltage output is provided to the LED lighting lamp 3, thereby providing lighting.
