Background
The light curtain target generally encloses a quadrilateral optical detection coordinate plane through a laser transmitter and a laser receiver, and when a bullet is shot to pass through the coordinate plane, a coordinate light path is shielded at an impact point, so that the corresponding laser receiver senses the interruption of the light path, and accordingly, the impact point coordinate is determined and corresponding target reporting data are given. The inventor finds that, in the research and development of the light curtain target, a frame structure surrounding a quadrilateral optical detection coordinate surface generally adopts opposite side vertical plates as carriers of an optical path transmitter and an optical path receiver. Although it is reasonable to install and adjust the transmitter and the receiver to realize the quadrilateral optical detection coordinate plane, the quadrilateral frame structure using the vertical plate as the positioning carrier may be dislocated or deformed during transportation, use or disassembly and assembly, which affects the stability of the optical path, thereby greatly increasing the reinforcement cost, and even if the reinforcement is performed in many ways, the effect is very small, and the ideal effect is not achieved. The inventor thinks that if the technical thought is changed, through the annular bottom plate and the vertical plate which extends along the outer side of the annular bottom plate, and the photoelectric device which forms the light path coordinate is installed by taking the upper surface of the annular bottom plate as a reference surface, the structural deformation factor can be reduced, the installation and positioning difficulty and the use and maintenance difficulty of the photoelectric device are reduced, the light path is kept stable, and the quality level of the light curtain target is improved. In view of the above, the present inventors have completed the present invention.
