The upper end of the lifting cylinder 4 is connected to the telescopic arm 1. Behind the telescopic arm 1, there is a drag chain assembly 5. On the right side of the telescopic arm 1, there is a folding arm 6. The top of the folding arm 6 is hinged with a locking assembly 9. The locking assembly 9 is installed at the top of the telescopic arm 1. In the middle of the inner side of the folding arm 6, there is a folding cylinder 8 connected to the locking assembly 9. Two groups of engineering lamps 10 are installed at intervals from top to bottom on the folding arm 6. Through the cooperation of the lifting cylinder 4 and the telescopic arm 1, the overall lifting adjustment function of the folding arm 6, the locking assembly 9 and the engineering lamp 10 is realized. Through the cooperation of the folding cylinder 8 and the folding arm 6, the unfolding and closing functions of the engineering lamp 10 are realized, and the state of the folding arm 6 is locked by the locking assembly 9.
[0029] An articulated middle frame 7 is provided outside the telescopic arm 1. A proximity sensor 20 is installed on one side of the folding arm 6, and a docking seat 50 is provided below the proximity sensor 20 corresponding to the articulated middle frame 7.
[0030] The telescopic arm 1 includes a main support arm 11, a first lifting arm 12 that is slidably sleeved and connected inside the main support arm 11, and a second lifting arm 13 that is slidably sleeved and connected inside the first lifting arm 12.

[0032] In this embodiment, the working principle of the telescopic arm is as follows: Since the top of the lifting cylinder is connected to the first lifting arm, one end of the second wire cable is connected to the wire fixing pin installed at the upper end of the first lifting arm and the other end is connected to the wire locking device. When the lifting cylinder is started, the lifting cylinder will drive the first lifting arm to rise. The first lifting arm will drive the second wire cable to move. Under the action of the upper fixed pulley, the second wire cable will drive the second lifting arm to rise through its lower end fixed to the wire locking device. Since the wire locking device is fixed inside the second lifting arm, when the second lifting arm rises, it will drive the first wire cable to move (one end of the first wire cable is connected to the wire locking device and the other end is connected to the wire fixing seat). Under the action of the lower fixed pulley, the end of the first wire cable connected to the wire locking device will move as the second lifting arm rises, thereby realizing the expansion and contraction of the main support arm, the first lifting arm, and the second lifting arm of the telescopic arm driven by the lifting cylinder, and realizing the height adjustment of the locking component, the folding arm, and the work lamp, so that the work lamp can be adjusted in height according to the actual lighting requirements, which is convenient to meet different lighting needs and greatly improves its practicability.

[0034] In this embodiment, the working principle of the drag chain assembly is as follows: Since the bottom of the locking assembly is connected to the top of the second lifting arm and the side of the locking assembly is connected to the vertical plate through the mounting plate, when the second lifting arm drives the locking assembly to rise, the locking assembly drives the vertical plate to rise through the mounting plate, and the vertical plate drives the chain plate to move inside the support plate, so as to ensure that the telescopic arm can extend and retract more stably and reliably.
[0035] An LED light box 30 is arranged inside the first lighting lamp 103. The LED light box 30 is composed of an upper box body 31 and a lower box body 32 connected by bolts 302.

[0036] In this embodiment, the solar panel on the upper part of the LED light box is fitted and installed on the top surface of the first lighting lamp, so that the solar panel can absorb solar energy for photoelectric conversion to provide electric energy; the lamp shade corresponds to the protection plate. When lighting, the protection plate is removed, and the battery outputs DC power to the LED light strips of the LED board, or the DC power is inverted into AC power through the power selector to provide AC power for small electric tools.
[0037] The present invention relates to a telescopic arm adjustable outdoor engineering lamp. During use, the hinged base 2 can install the device of the present invention at the lighting work area required for power engineering. The main arm 11, the first lifting arm 12, and the second telescopic arm 13 of the telescopic arm 1 are all slidably sleeved and connected. The main arm 11, the first lifting arm 12, and the second telescopic arm 13 of the telescopic arm 1 can be expanded and retracted by driving the lifting cylinder 4, so that the folding arm 6 and the main body of the engineering lamp 10 can be flexibly adjusted to different heights. Then, the folding cylinder 8 and the locking component 9 cooperate to drive the top end of the folding arm 6 to rotate around the hinge point with the locking component 9, realizing the movement of moving away from or approaching the telescopic arm 1, so as to realize the flexible adjustment of the main body of the engineering lamp 10 at different angles, making the device more practical.

[0040] In this embodiment, the working principle of the locking assembly is as follows: Since the bottom of the cross plate is fixedly connected to the top of the second lifting arm, and the cross plate is hinged to the folding arm through a hinge shaft, when the folding cylinder is started, the folding cylinder drives the folding arm to rotate around its hinge point with the cross plate through the cooperation of the articulated plate and the arc-shaped plate, so that the folding arm unfolds relative to the telescopic arm, realizing the adjustment of the illumination angle of the engineering lamp. After the angle is adjusted, after the locking card plate is clamped with the card slot of the V-shaped plate, the positioning of the locking card plate is realized through the cooperation of the articulated folding seat and the buckle, and the folding arm is locked at a certain angle state with the telescopic arm by the action of the folding cylinder.
