Description

Technical Field

[0001] This utility model relates to the field of laser ranging technology, specifically to a target component for testing the angular variation rate of a laser rangefinder. Background Technology

[0002] A laser rangefinder is an instrument that uses lasers to accurately measure targets. The measurement process includes measuring the laser spot diameter, which is also known as angular variation testing. In actual testing, the deviation between the laser angular variation and the adjusted data is verified, and rangefinders that do not meet the specifications are corrected. Currently, the angular variation of laser rangefinders is verified using specialized equipment, lacking substantial testing. To ensure the accuracy of the angular variation, this application proposes a target assembly for testing the angular variation of a laser rangefinder. Utility Model Content

[0003] To address the lack of substantive testing for the angular integral rate of existing laser rangefinders, this invention proposes a target assembly for testing the angular integral rate of laser rangefinders. The specific technical solution is as follows:

[0004] A target assembly for testing the angular variation rate of a laser rangefinder includes a target base, two transverse target plates, and two longitudinal target plates. The front side of the target base is provided with two target plate support arms in the vertical direction, and each target plate support arm has a slide rail on the side closest to the other target plate support arm. The two ends of each transverse target plate are respectively installed on the slide rail of its corresponding side target plate support arm, and the transverse target plates can move up and down along the target plate support arms. The two ends of each longitudinal target plate are respectively detachably installed on the rear side wall of its corresponding side transverse target plate.

[0005] Furthermore, the longitudinal and transverse target plates are assembled using splicing strips.

[0006] Furthermore, each target plate support arm is equipped with locking screws on its rear side for locking the position of the transverse target plate.

[0007] Furthermore, the target mount includes two vertically placed triangular supports, and two target plate support arms are respectively mounted on the two triangular supports.

[0008] The beneficial effects of this utility model are as follows:

[0009] The U-shaped target plate is composed of two horizontal target plates and two vertical target plates. The size of the U-shaped target plate can be adjusted according to the magnitude of the laser ranging angular variation rate to meet the testing requirements of different angular variation rates. In addition, the U-shaped target plate can be disassembled during transportation to reduce the space occupied by the U-shaped target plate and facilitate transportation. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] The present invention provides the following specific implementation scheme:

[0016] like Figure 1-2As shown, this utility model provides a target assembly for testing the angular variation rate of a laser rangefinder, comprising a target base 4, two transverse target plates 1, and two longitudinal target plates 5. A vertical target plate support arm 2 is provided on each of the left and right sides of the front side of the target base 4, and a slide rail 3 is provided on the side of each target plate support arm 2 closest to the other target plate support arm 2. The two ends of the upper transverse target plate 1 are respectively installed on the slide rail 3 of its corresponding side target plate support arm 2, and the two ends of the lower transverse target plate 1 are respectively installed on the slide rail 3 of its corresponding side target plate support arm 2. The transverse target plates 1 can move up and down along the target plate support arm 2. The upper ends of the two longitudinal target plates 5 are detachably installed on the rear side wall of the upper transverse target plate 1, and the lower ends of the two longitudinal target plates 5 are detachably installed on the rear side wall of the lower transverse target plate 1.

[0017] Furthermore, the longitudinal target plate 5 and the transverse target plate 1 are assembled by splicing strips, or they can be detachably connected by threads.

[0018] Furthermore, each target plate support arm 2 is provided with a locking screw on the rear side for locking the position of the transverse target plate 1.

[0019] Furthermore, the target holder 4 includes two vertically placed triangular supports, and two target plate support arms 2 are respectively mounted on the two triangular supports.

[0020] In use, the required size of the U-shaped target plate is determined based on the magnitude of the laser ranging angular variation. Then, on the assembled U-shaped target plate, the horizontal target plate 1 is first installed on the target plate support arm 2. After adjusting the position of the horizontal target plate 1, its position is locked. Subsequently, the vertical target plate 5 is installed in the designated position behind the horizontal target plate 1 as needed. When the size of the U-shaped target plate needs to be adjusted, the vertical target plate 5 is removed, the position of the horizontal target plate 1 is readjusted, and finally, the vertical target plate 5 is reinstalled.

[0021] The U-shaped target plate is composed of two horizontal target plates 1 and two vertical target plates 5. The size of the U-shaped target plate can be adjusted according to the magnitude of the laser ranging angular variation rate to meet the testing of different angular variation rates. In addition, the U-shaped target plate can be disassembled during transportation to reduce the space occupied by the U-shaped target plate and facilitate transportation.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
