[0021] like Figures 1 to 6 As shown, a solar street light which is convenient for replacing lamps comprises a lamp holder 1, the upper end of the lamp holder 1 is fixedly connected to a lamp stand, the upper end of the lamp stand is fixedly connected to a solar panel 4, the upper end of the lamp stand is located on one side of the solar panel 4 and is fixedly connected to a connecting arm 5, one end of the connecting arm 5 is fixedly connected to a lampshade 6, a lamp is installed in the lampshade 6, the lamp stand comprises a first lamp post 2 and a second lamp post 3, the first lamp post 2 is fixedly connected to the upper end of the lamp holder 1, the connecting arm 5 and the solar panel 4 are fixedly connected to the upper end of the second lamp post 3.

[0022] The upper end of the first lamp post 2 is fixedly connected to the hinged side plates 8 arranged correspondingly on both sides, and the lower end of the second lamp post 3 is fixedly connected and hinged to the connecting heads 9 between the hinged side plates 8 on both sides. The connecting heads 9 are fixedly connected to the rotating shafts on both sides. The hinged side plates 8 are provided with rotating holes that cooperate with the rotating shafts. The connecting heads 9 are provided with an arc-shaped limiting groove 16 on one side of the rotating shaft. The inner wall of the hinged side plates 8 is fixedly connected to a limiting slide post 15 slidably connected to the arc-shaped limiting groove 16. The limiting slide post 15 and the arc-shaped limiting groove 16 limit the swing of the connecting head 9. When the limiting slide post 15 slides to the upper end of the arc-shaped limiting groove 16, the first lamp post 2 and the second lamp post 3 are in a coaxial state. The first lamp post 2 is provided with an adjustment mechanism for driving the connecting head 9 to swing. The adjustment mechanism includes an adjustment groove located at the upper end of the first lamp post 2, and an electric push rod 10 is hinged in the adjustment groove. The upper end of the electric push rod 10 is hinged to the lower end of the connecting head 9.

[0023] The outer wall of the second lamp post 3 is slidably sleeved with a fixed cover tube 11, and the lower end of the fixed cover tube 11 is fixedly connected to a limiting plug plate 17. The first lamp post 2 is fixedly connected on both sides with limit sockets 18 that cooperate with the fixed cover tube 11. The limit sockets 18 are provided with limit slots that are arranged through and cooperate with the limit plug plate 17. One side of the limit sockets 18 is threadedly connected with a fixing bolt 19, and the limit plug plate 17 is provided with a fixing screw hole that is arranged through. The inner wall of the fixed cover tube 11 is fixedly connected with a slider 12, and the outer wall of the second lamp post 3 is provided with a slide groove 14 that cooperates with the slider 12, and the upper end of the slider 12 is fixedly connected with a fixing spring 13 located in the slide groove 14.

[0024] The lower end of the lampshade 6 is an open end, and a light-transmitting plate 7 is hinged in the opening of the lampshade 6. A limit ring 20 that cooperates with the light-transmitting plate 7 is fixedly connected in the lampshade 6. A locking mechanism is provided between the lampshade 6 and the light-transmitting plate 7. The locking mechanism includes a lock box 21 fixedly connected to the lower end of the lampshade 6, and a lock tongue 22 that cooperates with the light-transmitting plate 7 is slidably inserted in the lock box 21. A locking spring 23 that cooperates with the lock tongue 22 is fixedly connected in the lock box 21.

[0025] When the lamp needs to be repaired or replaced, the fixing bolts 19 on both sides are screwed out from one side of the limit socket 18, and the fixed cover tube 11 is pushed to drive the slider 12 to slide upward along the slide groove 14, and the fixing spring 13 is squeezed and deformed, so that the fixed cover tube 11 drives the limiting plug plate 17 to extend out of the limiting slot. At the same time, the fixed cover tube 11 is separated from the first lamp post 2 and slides upward along the outer wall of the second lamp post 3. The electric push rod 10 is started to drive the connecting head 9 to swing along the hinged plug plates on both sides. The connecting head 9 drives the first lamp post 2 to swing, and the lampshade 6 at one end of the first lamp post 2 swings to a position close to the ground, pushing the lock tongue 22 to slide into the lock box 21, squeezing the locking spring 23 to cause compression deformation, so that the lock tongue 22 falls off the bottom surface of the light-transmitting plate 7, and the light-transmitting plate 7 is opened. The internal lamp can be repaired and replaced. After completion, the lock tongue 22 is pushed into the lock box 21 again, pushing the light-transmitting plate 7 to swing into the lampshade 6, so that the inner wall of the light-transmitting plate 7 abuts against the lower end of the limit retaining ring 20, loosening the lock tongue 22, and pushing one end of the lock tongue 22 out of the lock box 21 under the restoring elastic force of the locking spring 23, so that the edge of the light-transmitting plate 7 abuts between the lock tongue 22 and the limit retaining ring 20, starting the electric push rod 10 to pull the connecting head 9 to swing back to the vertical state, so that the second lamp post 3 swings to the vertical state, and the slider 12 is pushed downward under the restoring elastic force of the fixing spring 13. The slider 12 drives the fixed cover tube 11 to slide downward along the outer wall of the second lamp post 3, so that the fixed cover tube 11 is sleeved on the outer wall of the first cover tube, and the limit rods on both sides are inserted into the limit slots on both sides, and the two fixing bolts 19 are screwed into the fixing screw holes again to prevent the limit plug plate 17 from detaching from the limit slot.
