Description

TECHNICAL FIELD

[0001] The utility model relates to the field of street lamp assembly, specifically to a lampshade lower shell structure integrally assembled with street lamp. BACKGROUND

[0002] The lampshade lower shell structure is an important component of the street lamp structure, which is located below the lampshade of the street lamp and mainly serves to protect the internal components such as the bulb, the reflective material and the circuit. The lampshade lower shell is usually made of materials with strong weather resistance and good corrosion resistance to ensure that it can work stably for a long time in outdoor harsh environments. In design, not only the aesthetics but also the heat dissipation performance should be considered to ensure that the heat generated by the bulb can be dissipated in time, thereby prolonging the service life of the street lamp. The sealing performance of the lampshade lower shell is also important, which can effectively prevent impurities such as rainwater and dust from entering the inside of the lamp body, thereby maintaining the normal operation of the street lamp.

[0003] Chinese patent CN112709971B discloses a lampshade assembly for LED street lamp, which comprises an upper shell and a lower shell. A cavity structure is formed between the upper shell and the lower shell. The side walls of the upper shell and the lower shell are provided with arc-shaped notches. The two arc-shaped notches are oppositely arranged and are mutually spliced to form a mounting hole for cooperating with the lamp pole of the street lamp. The upper shell and the lower shell are connected to form a lampshade structure, which simplifies the lampshade structure and improves the convenience of lampshade processing and assembly. At the same time, the installation area and the annular convex shell structure are arranged to facilitate the installation of the LED board outside and the installation of the electrical elements inside, thereby improving the overall installation convenience.

[0004] The lampshade assembly of the above-mentioned patent needs to longitudinally splice the upper shell and the lower shell to complete the connection during assembly. During maintenance and repair, it is difficult to separately disassemble the lower shell, and the entire LED street lamp needs to be disassembled to perform internal maintenance and repair, which is inconvenient for maintenance personnel. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a lampshade lower shell structure integrally assembled with street lamp. After the connecting strip is slid out from the outside of the main suspension strip, the lower shell can rotate around the connecting shaft as the center. The lower shell can rotate under the support of the bracket and the limiting strip and expose the internal mounting structure, thereby solving the problems in the above-mentioned background technology.

[0006] In order to achieve the above object, the utility model provides the following technical scheme: a lampshade lower shell structure integrated with street lamp assembly, including lower shell and upper shell, one side of lower shell is provided with connecting strip, the second installation groove is provided with the recess of connecting strip to lower shell, the extension strip is provided with the extension of lower shell to second installation groove, and extension strip is welded with lower shell fixedly, the inside of connecting strip is welded with main suspension strip to upper shell, and the outside of main suspension strip is connected with the inside sliding clamping groove of connecting strip.

[0007] Preferably, one side of the connecting strip is provided with a fixing piece, a first mounting groove is provided through the inside of the fixing piece, and a mounting hole is provided recessed in the inside of the connecting strip towards the first mounting groove.

[0008] Preferably, the lower end of the lower shell is provided with a support on the other side of the front and rear ends, a connecting block is provided between the two supports, and the connecting block and the lower shell are an integral structure.

[0009] Preferably, the connecting block and the support are rotatably connected through a connecting shaft.

[0010] Preferably, the other side of the connecting block is provided with a limiting strip, and the outside of the limiting strip is connected with the outside clamping groove of the connecting block.

[0011] Preferably, the other side of the limiting strip is provided with a standby suspension strip, and the standby suspension strip is welded with the lower end of the upper shell fixedly, and the outside of the standby suspension strip is connected with the inside clamping groove of the connecting strip.

[0012] Preferably, the front end of the connecting strip is provided with a first limiting piece, and the first limiting piece is welded with the connecting strip fixedly.

[0013] Preferably, the other end of the main suspension strip is provided with a second limiting piece, and the second limiting piece is welded with the main suspension strip fixedly.

[0014] Preferably, both sides of the lower shell are provided with a waterproof slope.

[0015] Compared with the prior art, the utility model has the beneficial effects as follows:

[0016] When assembling the lower housing of the lampshade and inspecting and installing the internal LED light-emitting positions, this utility model eliminates the need to drag the lower housing while removing the screws between the upper and lower housings. In this application, the lower housing extends into the second mounting groove inside the connecting strip via an extension strip, while the connecting strip slides and hangs outside the main suspension strip. The bolts used for fixing pass through the first mounting groove to fix the side of the connecting strip. When rotating or turning the screws, there is no need to worry about the lower housing losing its restraint and falling and causing damage. After removing the bolts used for fixing, the connecting strip can slide and be removed from outside the main suspension strip. At this time, the lower housing, which is no longer restrained, can rotate around the connecting shaft. The rotation can directly unfold the light-emitting structure wrapped between the lower and upper housings, making it convenient for users to inspect the interior and replace parts.
