Description

Technical Field

[0001] The utility model relates to the technical field of height measurement, in particular to a handheld earth height measuring instrument. Background Art

[0002] Conventional height measuring instruments use laser measurement technology to measure the height of the ground floor and the high points of objects. The laser transmitter and receiver will emit a laser beam through the transmitting lens to illuminate the target object. Ensure that the laser beam can accurately illuminate the target object and avoid being blocked by other objects. The laser beam is reflected back by the target surface. After the receiving lens of the laser transmitter and receiver receives the reflected light signal, it will transmit the distance data to the data processor. During this process, keep the body still, and the data processor will automatically calculate the distance between the target and the observation point, and display the result on the digital display. The value on the digital display can be directly read to obtain the height information of the target.

[0003] When using common handheld height measuring instruments, they are inevitably tilted because they are manually held, resulting in the line connecting the measurement base point and the end point being an oblique line instead of a vertical line, which leads to inaccurate height measurement results. Therefore, a handheld geodetic height measuring instrument is proposed to solve the above problem. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] Therefore, one purpose of the present invention is to provide a handheld geodetic height measuring instrument to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.

[0016] It is easy to tilt the machine body when measuring height by hand, so a weight structure is designed. The machine body is connected to the flange, the flange is connected to the shaft sleeve, and the bottom of the shaft sleeve is connected to the weight. The weight is always hanging down, which can always keep the machine body vertically downward. When the operator holds the machine body to measure the height, even if the hand shakes or tilts slightly, the weight will automatically adjust and guide the machine body back to the vertical state through the connection structure of the shaft sleeve and the flange. This automatic correction function greatly reduces the measurement error caused by human factors and ensures the accuracy of the measurement results. At the same time, there is a counterweight pointer on the back machine, which can display the posture of the back machine and the machine body in the other direction, and then adjust it manually.

This instant feedback mechanism makes the operation more intuitive and convenient, and reduces the difficulty of operation. It enables the machine body to be marked straight up for height measurement, making the height measurement results more accurate,

[0017] Preferably, in any of the above schemes, the bottom end of the weight is in a pointed cone shape, and the swing direction of the weight is perpendicular to the swing direction of the counterweight pointer.

[0018] The above technical solution is adopted: the design of the membrane button allows the machine to be started with just a light touch, reducing the impact on the machine body posture when touching.

[0019] The laser transmitter and receiver will emit a laser beam through the transmitting lens to illuminate the target object. Make sure that the laser beam can accurately illuminate the target object and avoid being blocked by other objects. The laser beam is reflected back by the target surface. After the receiving lens of the laser transmitter and receiver receives the reflected light signal, it will transmit the distance data to the data processor. During this process, keep the body still, the data processor will automatically calculate the distance between the target and the observation point, and display the result on the digital display. You can directly read the value on the digital display to obtain the height information of the target.

[0020] Preferably, in any of the above schemes, the back machine is located directly behind the machine body, and the top end of the handle is threadedly connected to the back machine.
