[0021] A plurality of lamp beads (not shown in the drawings) are fixed on the lamp body mounting portion 21, and the lamp beads face the photometric lens 30. A battery box and a control main board are fixed inside the lamp housing 10. A control button is fixed on the upper part of the lamp housing 10, and the upper end of the control button extends out of the top surface of the lamp housing 10, and the bottom end of the control button extends into the lamp housing 10 and contacts with the upper end of the control switch electrically connected to the control main board. The lamp beads, the battery box and the control button are electrically connected to the control main board via electrical connecting wires. This is a conventional structure and will not be described in detail here.
[0022] The lamp housing 10 is an engineering plastic housing with high strength and good effect. The bottom end of the lamp housing 10 is formed with a first connecting portion 11 extending downward, and the bottom end of the first connecting portion 11 is formed with a cylindrical sleeve portion 12, which is inserted between the two front connecting extension portions 41 of the fixing frame 40 provided below the lamp housing 10, and the screw portion of the fixing bolt 1 is inserted into the through hole of the middle axis of the cylindrical sleeve portion 12, and the cylindrical sleeve portion 12 is fixed to the fixing frame 40 by the fixing bolt 1; a plurality of positioning slots 121 are formed on the outer wall of the cylindrical sleeve portion 12, and a connecting portion 42 is formed between the rear parts of the two connecting extension portions 41 of the fixing frame 40, and an elastic sheet 43 is installed on the connecting portion 42, and the front end of the elastic sheet 43 extends out of the front wall surface of the connecting portion 42 and is inserted into one of the positioning slots 121 formed on the outer wall of the cylindrical sleeve portion 12.
[0023] A slot is formed in the middle of the front wall surface of the connecting portion 42 , and a clamping portion 431 is formed in the middle of the rear end surface of the elastic sheet 43 . The clamping portion 431 is clamped in the slot.
[0024] Furthermore, a circular recessed hole 411 and a hexagonal recessed hole 412 are respectively formed on the outer side walls of the two connecting extension portions 41, and a through hole is formed in the middle of the inner ends of the circular recessed hole 411 and the hexagonal recessed hole 412. The hexagonal nut 2 is inserted into the hexagonal recessed hole 412 and cooperates with the hexagonal recessed hole 412. The rotating part of the fixing bolt 1 is inserted into the circular recessed hole 411, and the screw portion of the fixing bolt 1 is inserted into all the through holes, and the middle axis of the cylindrical sleeve portion 12 passes through the through hole and the hexagonal recessed hole 412, and the end of the screw portion of the fixing bolt 1 is threadedly connected to the corresponding hexagonal nut 2. Two anti-slip washers 3 are inserted on the screw portion of the fixing bolt 1, and the anti-slip washers 3 are clamped between the inner wall surface of the corresponding connecting extension portion 41 and the corresponding end surface of the cylindrical sleeve body portion 12; the inner end surface of the rotating portion of the fixing bolt 1 is pressed against the inner end surface of the corresponding circular recessed hole 411, and one end surface of the hexagonal nut 2 is pressed against the inner end surface of the hexagonal recessed hole 412.
[0025] When it is in use, when it is necessary to adjust the illumination angle of the lamp bead, the fixing bolt 1 can be loosened, and then the lamp housing 10 can be rotated forcefully so that the elastic sheet 43 enters the corresponding positioning slot 121 to achieve auxiliary positioning, and then, the fixing bolt 1 can be tightened to achieve fixation. When it is in use, when the hexagonal nut 2 is turned, it is inserted into the corresponding positioning slot 121 through the elastic sheet 43, so that the rotation amplitude of the lamp housing 10 is the movement amplitude of the elastic sheet 43 inserted into the corresponding positioning slot 121, thereby ensuring that the lamp housing 10 can be used for normal illumination and will not be affected by excessive rotation.
[0026] Further, the front inner wall of the lamp housing 10 is formed with an annular groove, the rear part of the upper part of the annular groove is formed with an upper groove 13 extending backward, the inner wall surface of the annular groove in front of the upper groove 13 is formed with an upper protruding clamping portion 131, the bottom surface of the lower part of the annular groove is formed with a through groove extending downward, the rear end surface of the through groove is formed with an elastic clamping portion 132 extending outward and forward, the front end of the elastic clamping portion 132 extends out of the front end surface of the lamp housing 10, and the inner wall surface thereof is formed with a protruding clamping portion 131. A lower clamping portion 133 is formed, and an annular clamping portion 23 extending backward is formed on the edge of the rear end face of the front annular sleeve 20. The annular clamping portion 23 is clamped in the annular groove. A rear protrusion 231 extending backward is formed on the rear wall surface of the upper part of the annular clamping portion 23. An upper clamping groove 232 is formed on the top surface of the upper part of the annular clamping portion 23 at the front of the rear protrusion 231. The rear protrusion 231 is inserted into the upper groove 13, and the upper protrusion clamping portion 131 is clamped in the upper clamping groove 232.
[0027] The bottom surface of the front annular sleeve 20 at the front end of the lower part of the annular clamping portion 23 is formed with a lower mounting portion 24 extending downward, a through groove 241 is formed in the middle of the lower mounting portion 24, and an inner groove 25 is formed on the bottom surface of the front annular sleeve 20 at the front part of the through groove 241. The front part of the elastic clamping portion 132 is inserted into the through groove 241, and the lower clamping portion 133 formed on the top surface of the front end of the elastic clamping portion 132 is clamped in the inner groove 25.
[0028] By adopting the above method, it is only necessary to turn the elastic clamping portion 132 outward so that the lower clamping portion 133 is disengaged from the inner groove 25, and then the front annular sleeve 20 can be removed from the lamp housing 10 for disassembly, which is very convenient.
[0029] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
