Description

Technical Field

[0001] The utility model relates to a pole lamp, in particular to a pole lamp which is easy to disassemble and has an adjustable angle. Background Art

[0002] Pole lamps are often used as garden lamps and are more common in life. Their structure generally includes a lamp pole and a lamp holder. The lamp holder is fixed at the upper end of the lamp pole. In order to facilitate the adjustment of the lighting angle of the lamp holder, the lamp holder is usually designed as an angle-adjustable structure. The rear end of the lamp holder is plugged into the upper end of the lamp pole, and the two can be rotated to adjust the angle. After the angle is adjusted, a screw is screwed in, and the end of the screw is pressed on the inner wall of the rear end of the lamp holder, so that the lamp holder is fixed. It has certain limitations in actual use and is usually suitable for straight lamp poles. When encountering an inverted L-shaped lamp pole with the lamp holder facing downward and the lamp holder is required to rotate in the vertical direction, the lamp holder is affected by its own gravity. The above fixing method is not stable and needs further improvement. Utility Model Content

DETAILED DESCRIPTION

[0015] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0016] like Figure 1 — Figure 3As shown, a pole lamp which is easy to disassemble and has adjustable angles comprises a lamp pole 1 and a lamp holder 2, the lamp pole 1 is in an "inverted L-shape", a first connecting rod 3 is fixed to the front upper end of the lamp pole 1 by a threaded connection, the front end of the first connecting rod 3 has a first circular connecting block 31, a fixing rod 4 is fixed to the upper end of the lamp holder 2 by a threaded connection, a second connecting rod 5 is fixedly connected to the rear end of the fixing rod 4, the rear end of the second connecting rod 5 has a second circular connecting block 51, the second circular connecting block 51 is rotatably connected to the first circular connecting block 31, the right end of the first circular connecting block 31 has a first toothed disc 311, the left end of the second circular connecting block 51 has a second toothed disc 511 meshing with the first toothed disc 311, and the second circular connecting block 51 is locked to the first circular connecting block 31 by a locking structure.

[0017] like Figure 2 and Figure 3 As shown, in order to facilitate the disassembly of the lamp pole 1 , the rear end of the first connecting rod 3 has a first threaded portion 312 , and the front upper end of the lamp pole 1 has a first threaded hole 11 , and the first threaded portion 312 is screwed into the first threaded hole 11 .

[0018] like Figure 2 and Figure 3 As shown, in order to facilitate the removal of the lamp holder 2 , the upper rear portion of the lamp holder 2 has a second threaded hole 21 , and the front end of the fixing rod 4 has a second threaded portion 41 , which is screwed into the second threaded hole 21 .

[0019] like Figure 2 and Figure 3 As shown, the rear end of the fixing rod 4 has a circular boss 42, the front end of the second connecting rod 5 has a socket 52, the boss 42 is inserted into the socket 52, the side wall of the second connecting rod 5 has a third threaded hole 53 that penetrates inside and outside, a set screw 6 is screwed into the third threaded hole 53, and the inner end of the set screw 6 is pressed on the outer wall of the boss 42. After the set screw 6 is unscrewed, the fixing rod 4 can be pulled out.

[0020] The locking structure is a locking knob 7, which has a screw rod 71 extending left and right. The right end of the second circular connection block 51 has a through hole 512 that passes through the inside and outside, and the left end of the first circular connection block 31 has a fourth threaded hole 313. The screw rod 71 passes through the through hole 512 and is screwed to the fourth threaded hole 313.
