Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rangefinders, in particular to a rangefinder. Background Art
[0002] The rangefinder is an instrument designed for measuring length and distance by utilizing the reflection and interference characteristics of light, sound, and electromagnetic waves. Based on the length measurement, the new rangefinder can use the length measurement results to scientifically calculate other parameters such as the area, circumference, volume, and mass of the target to be measured. It has a wide range of applications in engineering applications, GIS surveys, military and other fields. The existing handheld rangefinder requires workers to hold the distance for distance measurement, but in the case of long-term use, the measurement method of holding the rangefinder by hand will make the user tired, especially when it takes a long time to maintain a posture. The weight of the rangefinder puts more pressure on the user's wrist. In addition, most of the existing handheld measuring instruments are measured by laser, so the proper protection of the laser head will directly affect the measurement accuracy of the equipment. The existing handheld rangefinder generally does not have a mechanism to protect the laser head. For this reason, we propose a rangefinder to solve the above problems. Utility Model Content

[0022] Two groups of connection blocks 3 are fixedly installed on the lower side of the mounting frame 2, and a wrist wrap 4 is fixedly installed on the connection block 3. A first adhesive sheet 5 is arranged on the front side of the right end of the wrist wrap 4, and a second adhesive sheet 6 is arranged on the rear side of the right end of the wrist wrap 4.
[0023] An adjustment mechanism, which is arranged on the mounting frame 2 and is used to adjust the position of the rangefinder body 1;
[0024] A shielding mechanism is provided on the upper side of the rangefinder body 1 and is used to shield the laser head of the rangefinder body 1. The device allows the rangefinder body 1 to be fixed on the user's hand through a wrist wrap 4 that can be bound, so that the user will not be too tired when using the rangefinder body 1 for a long time. An adjustment mechanism is also provided so that the position of the rangefinder body 1 can be adjusted, thereby increasing the adaptability of the device when in use;
[0025] Furthermore, the rear side array of the wrist wrap 4 is laterally provided with rubber pads 7, and the rubber pads 7 are arranged in a staggered manner on the rear side of the wrist wrap 4, such as Figure 2 As shown, this structure allows the wrist wrap 4 to be more stable when fixed on the user's hand, while having good air permeability.
[0026] Further, the adjustment mechanism includes a mounting frame 2, a rotary block 12 is rotatably mounted on the mounting frame 2 on the left side, first movable grooves 8 are provided on both sides of the rangefinder body 1, a movable block 9 is fixedly mounted on the upper end of the mounting frame 2, a limit hole 10 is provided on the movable block 9, a limit rod 11 is fixedly installed in the first movable groove 8, a torsion spring 13 is provided at the rotation connection between the rotary block 12 and the mounting frame 2, a second movable groove 14 is provided on the mounting frame 2, and limit grooves 15 are provided on both sides of the first movable groove 8 on the left side, and one end of the rotary block 12 is engaged in the limit groove 15, such as Figure 2 and Figure 4 As shown, this structure allows the relative position of the rangefinder body 1 and the mounting bracket 2 to be adjusted, so that the device can be adapted to different usage situations and users.
[0027] Furthermore, the diameter of the lower end of the limiting rod 11 is smaller than the diameter of the upper side, the movable block 9 is elastic and an opening is provided on one side of the limiting hole 10, such as Figure 2 and Figure 4 As shown, this structure allows the mounting bracket 2 to be detached from the rangefinder body 1, so that the mounting bracket 2 can be disassembled when it is not needed, thereby increasing the adaptability of the device when in use.
[0028] Furthermore, the rear side of the mounting frame 2 is arc-shaped, and the edge of the rear side of the mounting frame 2 is rounded. Figure 2 As shown, this structure makes the mounting bracket 2 less stressful for the user's hand, making the user more comfortable to use.

At this time, the lower end of the rotary block 12 is disengaged from the limit groove 15. At this time, the relative fixation between the mounting frame 2 and the rangefinder body 1 is released, and the relative position of the rangefinder body 1 and the mounting frame 2 can be adjusted and locked. Similarly, when the laser head needs to be shielded, slide the shielding iron plate 16 so that the shielding iron plate 16 is on the upper side of the rangefinder body 1, and at the same time, it can be adsorbed with the magnetic suction block 18. The above is the entire working principle of the utility model.
