Description

Technical Field

[0001] The utility model belongs to the technical field of measuring instruments and relates to a laser rangefinder. Background Art

[0002] A laser rangefinder is an instrument that accurately measures the distance to a target using a laser. When the laser rangefinder is working, it emits a very thin laser beam towards the target. The laser beam reflected by the target is received by a photoelectric element, and a timer measures the time from the emission to the reception of the laser beam to calculate the distance from the observer to the target.

[0003] When a traditional rangefinder is used outdoors, due to the overly strong sunlight, the user cannot clearly identify the laser point and cannot accurately aim at the measurement target. The Chinese utility model patent with the patent number CN209514065U discloses a handheld rangefinder with a camera function. By assisting the measurement with the camera, the measurement target can be clearly aimed at on the display, and then accurate measurement can be carried out.

[0004] However, this rangefinder has the following disadvantages: Since the orientation of the camera is the same as that of the laser emitter and the receiving lens, when in use, the camera points to the measurement target and the display faces upward, and the user needs to lean forward to view the display. When the position of the measurement target is relatively low, the orientation of the camera is obliquely downward, resulting in an angle at which the user holds the device and making it impossible to clearly view the display.

[0005] To solve the above problems, if the positions of the camera, the laser emission unit, and the receiving and processing unit are rotated by 90° conventionally to make the display face the user, although the problem of the viewing angle of the display can be solved after such adjustment, since the lengths of the laser emission unit and the receiving and processing unit themselves are relatively long, if they are rotated as a whole by 90°, it will cause a significant increase in the thickness of the rangefinder, thus affecting the overall aesthetics of the rangefinder. Summary of the Utility Model

[0006] The purpose of the present utility model is to address the above problems existing in the existing laser rangefinders and propose a rangefinder that can make the display face the user while keeping the positions of the laser emission unit and the receiving and processing unit unchanged.

[0007] The purpose of the present utility model can be achieved by the following technical solutions:

The display screen is fixedly embedded in the front of the housing, the camera faces the back of the housing, the orientations of the laser emitter and the laser receiver are the same and different from the orientation of the camera. It is characterized in that a reflecting plate is further arranged in the housing, and the reflecting plate is used to change the orientations of the laser emitted by the laser emitter and the laser received by the laser receiver, so that the laser emitted and received by the rangefinder has the same orientation as the camera.

[0016] In the above-mentioned laser rangefinder, a charging socket is arranged at the bottom of the housing.

[0017] In the above-mentioned laser rangefinder, a start button is provided on the side of the housing.

[0018] Compared with the prior art, without changing the installation positions of the laser emitter and the laser receiver, the present utility model changes the laser orientation of the laser emitter and the laser receiver through a reflector, making the laser orientation consistent with the camera orientation, without increasing the thickness of the housing, and having a beautiful appearance. When in use, the laser emitter, the laser receiver, and the camera perform measurements on the back of the housing, and the display screen on the front of the housing faces the user for convenient viewing.
