Description

Technical Field

[0001] The utility model relates to the field of clinical technology, in particular to a portable two-dimensional measuring instrument. Background Art

[0002] Usually people use distance detectors in daily operations such as experiments, house inspections, material division, etc. The current distance meter can only detect the horizontal degree between points. If the height needs to be measured at the horizontal position, the operation is complicated and often requires two people to use it together to accurately measure. Only a single measurement of length cannot meet people's measurement requirements. The two-dimensional infrared horizontal distance meter can determine the horizontal position and measure the distance, and can also meet the needs of measuring the height distance at the horizontal position.

[0003] With the development of science and technology, the requirements for measurement methods are getting higher and higher. At present, simple measurements are mainly carried out by using tape measures. Most of the current tape measures can only measure lengths, and most of the existing horizontal indoor distance meters are infrared monochromatic lasers that measure horizontal distances. However, if it is necessary to continue to measure the height at a horizontal position, and the operation is complicated, it often requires two people to use it together to accurately measure. The single measurement of length cannot meet people's requirements for measurement and greatly affects the accuracy of the measurement; for example, in the process of measuring clinical intracranial pressure, it is necessary to use a two-dimensional measuring instrument to aim the light at the external auditory canal as the pressure starting point, and then use the starting point to check the height position of the liquid in the pipe for measuring intracranial pressure, and evaluate the size of the intracranial pressure by the height of the liquid. In the existing process, the various components are bundled and used in combination, and the measurement accuracy is not high and the operation is inconvenient, and it is easy to misread or read the wrong pressure value; in order to solve the above problems, the utility model provides a portable two-dimensional measuring instrument to solve the above problems.

[0006] The advantage of the utility model is that after a folding ruler is arranged on the shell and the measuring instrument is placed in a horizontal position, the folding ruler is extended out of the shell to measure the height, and the folding ruler can be retracted into the shell when not in use, thereby reducing the tediousness of clinical intracranial pressure measurement and ensuring the accuracy of measurement. The accuracy of the measurement base point and the accuracy of the height measurement are ensured by the first level meter and the second level meter.

[0007] Furthermore, the measuring length of the foldable ruler is 0.2-4 m, and it is coaxially arranged through a plurality of telescopic joints, and scale lines are provided on the telescopic joints.

[0008] Preferably, the folding ruler takes the emission point of the emitting lamp as the starting point, and the emission point to the upper surface of the shell is used as the reference scale. The scale is stabilized according to the actual setting of the shell, and scale lines are marked on the shell. The scale lines of the folding ruler are superimposed and accumulated on this basis to ensure the measurement accuracy of the folding ruler.

[0009] Furthermore, the first level and the second level are mounted on the housing by means of spring compression, and the spring provides a buffering protection for the first level and the second level, thereby ensuring the measurement accuracy of the first level and the second level.

[0010] Furthermore, the measuring instrument further comprises a fixing device, which is connected to the side of the housing by a buckle. The setting of the fixing device is not convenient for adjusting the starting point of the measuring instrument to adapt to measuring different objects and ensure the accuracy of the measurement.

[0011] Furthermore, the fixing device comprises a bracket, and a handle is provided on the bracket, and the handle can be folded and retracted when not in use. The provision of the handle facilitates the transport and transfer of the bracket, improves the convenience of use and reduces obstruction.

[0012] Furthermore, the lower end of the bracket is provided with a foldable triangular support leg, and the height of the bracket is 0.5-1.5m. The setting of the triangular bracket is convenient for improving its use convenience and reducing obstacles. The triangular bracket can also be replaced by a base to ensure the stability of the bracket.

[0013] Furthermore, the buckle on the side of the shell is provided with a fastening bolt, and the buckle is detachably set on the bracket through the bolt; during use, the buckle can also be directly clamped on other components to ensure the measurement accuracy of the measuring instrument.

[0014] Furthermore, the buckle is a U-shaped buckle, which improves the convenience of using the buckle.

[0015] The utility model has the following characteristics: the utility model has a simple structure, and the level of the measuring instrument can be ensured by the emitting lamp, and the height is measured in the horizontal state to ensure the measurement accuracy, which solves the problem that the current single measurement of length cannot simultaneously meet the height measurement, and solves the problem that the manual measurement of height based on the measuring instrument has large errors; the starting point of the folding ruler is set at the emitting point of the emitting lamp, and the folding ruler is perpendicular to the light of the emitting lamp to ensure the measurement accuracy.
