Description

Technical Field

[0001] The utility model relates to the technical field of targets, and particularly relates to a night vision target. Background Art

[0002] A target refers to a frame set at a triangulation point or a precise traverse point for observation. The center of the aiming part of the target is located on the plumb line of the triangulation point or the traverse point, and is used for a total station to perform aiming and observation. The conventional measurement method is to set a laser centering instrument below the measurement mark point, and use the laser emitted by the laser centering instrument as the plumb position for centering and leveling. Common targets are equipped with prisms, and the prisms are illuminated by lights for the total station instrument to aim at, observe, and measure the target.

[0003] However, in some working environments with dim light, such as at night, the observers cannot accurately find the erection position of the target. At this time, other operators need to shake the lighting lamp at the prism so that the observers can find the erection position of the prism. And during the process of the observers observing the prism, other operators also need to illuminate the prism with the lighting lamp for observation. The whole process is time-consuming and laborious. Content of the Utility Model

The light source 22 is arranged inside the housing 21, the diaphragm member 23 is arranged at one end of the housing 21, and the lens 24 is arranged inside the housing 21 and between the light source 22 and the diaphragm member 23. Among them, the center point of the opening of the diaphragm member 23 and the light beam emitted by the laser emitter 13 are both located on the axis of rotation of the fixing part 11 around the movable part 12.

[0026] In this specific embodiment, the fixing part 11 includes a base 111 and a first shaft body 112. The first shaft body 112 is fixedly connected to the base 111. The movable part 12 includes a cover body 121, a second shaft body 122 and a mounting bracket 123. The second shaft body 122 is coaxially and rotatably arranged inside the first shaft body 112.

[0027] The laser emitter 13 is fixedly arranged at the bottom end of the second shaft body 122. The top end of the second shaft body 122 is fixedly connected to the cover body 121. The cover body 121 is fixedly connected to the mounting bracket 123. The mounting bracket 123 is rotatably connected to the housing 21.

[0028] On the basis of the above solution, in order to prevent serious wear when the first shaft body 112 rotates with the first shaft body 112, specifically, an annular space is formed between the top ends of the first shaft body 112 and the second shaft body 122, and a plurality of rolling bodies 10 are arranged in the annular space. Among them, the rolling body 10 is a round steel ball.

[0029] In addition, in order to realize the functions of unlocking and locking between the fixing part and the movable part, specifically,

[0030] One side of the cover body 121 is rotatably connected with a locking member 14 in a threaded manner. The locking member 14 can be in contact with or separated from the first shaft body 112.

[0031] It should be noted that the locking member 14 is a threaded rod rotatably connected to one side of the cover body 121 in a threaded manner. A handle is arranged at one end of the threaded rod. By holding the handle and rotating the threaded rod, the other end of the threaded rod can be in contact with the first shaft body 112, and the relative rotation between the first shaft body 112 and the second shaft body 122 can be restricted.

[0040] In this specific embodiment, an installation plate is provided inside the housing, and the light source is fixedly arranged on one side of the installation plate.

[0041] One end of the lens barrel 25 abuts against the other side of the installation plate, and the other end of the lens barrel 25 is also fixedly connected to the adjustable diaphragm 231.

[0042] On the basis of the above solution, in order to facilitate the installation of the night vision aiming mark, a leveling base 3 is further included. The base can be fixedly connected to the leveling base. It should be noted that the leveling base is not limited to a certain specific structure, as long as it can ensure that when installed at an uneven position, the axes of the first shaft body 112 and the second shaft body 122 are perpendicular to the horizontal ground, and no other details will be elaborated here.

[0043] In addition, a through hole needs to be opened in the leveling base 3 to ensure that the first shaft body 112 and the second shaft body 122 can pass through the through hole, and the light emitted by the laser emitter 13 can irradiate the ground.

[0044] On the basis of the above solution, a spirit level 4 is arranged on the cover body 121. Specifically, the spirit level 4 can be a commonly used bubble in the market. By cooperating the spirit level 4 with the leveling base 3, it is ensured that the axes of the first shaft body 112 and the second shaft body 122 are perpendicular to the horizontal ground.
