Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to an electronic height measuring device for infant physical examination instruments. Background Art

[0002] At present, the measuring device for measuring the height of infants and young children usually adopts the emission and recovery of ultrasonic and infrared signals, or prints a scale to measure. When the infants and young children lie flat on the measuring platform, the sliding plate is moved to emit the measuring signal to obtain the measured distance, or the data is read by the corresponding scale of the pointer of the measuring board. For example, the Chinese utility model patent with the authorization announcement number CN 209639813 U discloses a height and weight measuring instrument for infants, including a base and a tray, the tray has a rectangular groove for infants and young children to lie down, and a distance measuring structure is arranged on the tray, the distance measuring structure includes a movable baffle arranged in the rectangular groove, and an infrared emitting unit and an infrared receiving unit are arranged on a side wall of the rectangular groove opposite to the movable baffle, which can measure the height of infants and young children.

[0003] Defects and shortcomings of the existing technology:

[0004] 1. When the ambient air humidity and air temperature are different, the signal propagation speed is also different. As the measurement distance increases, a certain attenuation will occur, thus causing measurement errors;

[0005] 2. When measuring, the obstruction or interference of external objects and the interference of other signals will affect the accuracy of the measurement.

[0006] Therefore, we proposed an electronic height measuring device for infant physical examination instrument to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1-2 As shown, an electronic height measuring device for a physical examination instrument for infants and young children proposed in one embodiment of the utility model comprises a guide rail 1, a mounting frame 4 and a fixed grid 5 placed parallel to the guide rail 1, a slider 2 is slidably connected to the guide rail 1, a sensor small board housing 3 is mounted on the mounting frame 4, a sensor small board 7 is assembled in the sensor small board housing 3, a measuring board 8 is fixed on the other side of the mounting frame 4, and the connection line of the sensor small board 7 is received by a micro drag chain 6 and connected to the main board at the other end;

[0024] Installation and preparation: Install the various components of the device in the arc-shaped housing, ensuring that they are firmly installed.
