Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Light receiving element as shown in Figures 2 and 3, comprise shell 1, the lock pin 2 be located in shell, Connection Block 3 and photelectric receiver 4, the end of described shell 1 is installed and is provided with cover headstock 5, described Connection Block 3 is connected with cover headstock 5, the end of described lock pin 2 is passed described cover headstock 5 and is inserted in described Connection Block 3, described lock pin 2 in being oppositely arranged, is provided with the first optical filter 6 intercepting lock pin 2 and photelectric receiver 4 with photelectric receiver 4 in described Connection Block 3.First optical filter 6 is for filtering light signal.
The above forms agent structure of the present invention.
The present invention also comprises the inner sleeve 7 be rotatably connected with Connection Block 3, the end sidewalls of described Connection Block 3 is arranged with a pair in order to make the breach of inner sleeve 7 left-right rotation, the outer wall of described inner sleeve 7 is respectively equipped with the first connecting hole, and the first pilot hole to be symmetrical set with the first connecting hole, the sidewall of described Connection Block 3 is respectively equipped with second connecting hole corresponding with the first connecting hole, and second pilot hole corresponding with the first pilot hole, straight pin 8 is inserted with between described first connecting hole and the second connecting hole, register pin 9 is inserted with between described first pilot hole and the second pilot hole, described first pilot hole, second pilot hole, and the cross section of register pin 9 is the corresponding regular polygon structure arranged.
The present invention is by arranging inner sleeve 7, and in the end sidewalls of Connection Block 3, be symmetrical arranged the breach matched with inner sleeve 7, inner sleeve 7 is rotatably connected with Connection Block 3 by straight pin 8, register pin 9, when needing the angle position regulating photelectric receiver 4, take off register pin 9, then inner sleeve 7 is rotated, inner sleeve 7 is made to drive photelectric receiver 4 with straight pin 8 for axle swings, when turning to correct position as required, again register pin 9 is inserted in the second pilot hole, the first pilot hole successively.Cross section due to the first pilot hole, the second pilot hole and register pin 9 is the corresponding regular polygon structure arranged (as shown in Figure 3, as a kind of embodiment, the present invention adopts cross section to be the register pin 9 of regualr decagon structure), coordinated with the first pilot hole, the second pilot hole by register pin 9, can be fixed the angle position of inner sleeve 7.The present invention, by regulating the angle of photelectric receiver 4, effectively improves the reception of signal, uses more convenient.It is pointed out that limit, the cross section number of the first pilot hole, the second pilot hole and register pin 9 is more, the angular adjustment precision of photelectric receiver of the present invention is higher.
Described Connection Block 3 is provided with snap close, and one end of described snap close is provided with the lock nut A10 coordinated with straight pin 8, and the other end of snap close is provided with the lock nut B11 coordinated with register pin 9.By arranging lock nut A10 and lock nut B11, effectively prevent straight pin 8, phenomenon that register pin 9 drops, locking action being served to the present invention, when needing to regulate the angle of photelectric receiver 4, only need take off lock nut B11.
