And the length of the adjusting column 24 is matched with that of the connecting column 22, so that the components can be tightly connected when in use.
In a normal state, the top of the adjusting column 24 is positioned in the through hole 27, and the sealing ring 29 is attached to the inner wall of the through hole 27; the screw-connection part 31 of the adjusting column 24 is in screw connection with the internal thread section 32 of the connecting column 22, so that the adjusting column 24 can be stably positioned at the height position and cannot fall down; and the driving end 30 is separated from the adjusting hole 26, so that the adjusting column 24 will not rotate the connecting column 22 and the transparent plate 16.
When the angle of the light-transmitting plate 16 needs to be adjusted, a tool is inserted into the jack 28 at the top of the adjusting column 24, the adjusting column 24 is rotated, the threaded portion 31 is separated from the internal thread section 32 (the connecting column 22 is connected with the disc 20 more tightly, and the connecting column 22 cannot be driven by the adjusting column 24 at this time), then the adjusting column 24 is pushed downwards, the driving end 30 is inserted into the adjusting hole 26, and the adjusting column 24 is rotated at this time to drive the connecting column 22 to rotate, so that the light-transmitting plate 16 is driven to rotate.
The actuating end 30 is disengaged from the adjustment aperture 26 by lifting the adjustment post 24 upward after rotating the light-transmitting panel 16 into position. After the screw-threaded portion 31 approaches the internal thread section 32, the adjusting post 24 is rotated to screw the screw-threaded portion 31 onto the internal thread section 32 (at this time, the connecting post 22 is still not rotated), and the top of the adjusting post 24 is inserted into the through hole 27 to seal the through hole 27.
Through such design make adjust post 24 more rationally set up on burying the lamp underground, adjust post 24 more stable when making not need to adjust, it is also very convenient when needing to adjust.
The middle of the disc 20 is provided with a rotating shaft 34 and a limiting sheet 38, the bottom of the connecting column 22 is provided with a rotating groove 37 and a rotating hole 36, so that the connecting column 22 can be rotatably connected to the middle of the disc 20, the connecting column 22 is tightly connected with the disc 20, and the rotation of the adjusting column 24 cannot drive the connecting column 22 to rotate when the driving end 30 is not inserted into the adjusting hole 26.
The top of the rotating shaft 34 is provided with a convex ring 35, the convex ring 35 is tightly attached to the inner wall of the rotating hole 36 after being inserted into the rotating hole 36, so that the connecting column 22 and the disc 20 have a tight connection relationship, and the connecting column 22 and the light-transmitting plate 16 cannot shake in a use state, thereby ensuring that the light-transmitting plate faces a correct indication direction.
The rotating shaft 34 and the convex ring 35 are inserted into the rotating hole 36 to play roles of connection and limitation, the disc 20 is further provided with a limiting piece 38, and the limiting piece 38 also plays a certain limiting role after being inserted into the rotating groove 37, so that the connecting column 22 can be very stable under the limiting effect of the rotating shaft 34 and the limiting piece 38, and cannot shake around, and the light-transmitting plate 16 is smoothly arranged below the panel 12.
A spring 39 is also arranged in the adjusting hole 26, and the top end of the spring 39 is attached to the bottom of the adjusting column 24. The spring 39 is of a suitable height so that the top of the spring 49 abuts the bottom of the adjustment post 24 when the top of the adjustment post 24 is inserted into the aperture 27.
The spring 39 compresses when the adjustment post 24 is pressed downward to allow the driver end 30 to be inserted into the adjustment aperture 26. When it is desired to lift the adjustment post 24, the tool is released and the driving end 30 can be pushed out of the adjustment hole 26 by the spring force of the spring 39, allowing the adjustment post 24 to move up and down easily.
The jack 28 sets up to the allen key structure for can adjust it through the allen key when adjusting, and the allen key is the instrument very commonly used, and such setting makes ground bury the lamp and need not dispose special instrument, very facilitate the use. The plug 33 is provided at the insertion hole 28, and the plug 33 shields the insertion hole 28 in a normal state, so that foreign matters do not fall into the insertion hole 28, thereby protecting the insertion hole 28.
It can be seen that the underground lamp with the structure is reasonable in design, and can be adjusted quickly according to actual conditions during use to form a correct indication line and improve management efficiency of public places.
