[0002] In order to better monitor the health of their children, parents will measure their children's height at different ages to understand the growth of their children. At present, parents generally use a tape measure to measure the height of their children, but the tape measure is inconvenient to use and is prone to inaccurate measurement. There is also another bench-type measuring device, which takes up a large space and is not convenient to store.

[0003] To this end, the scheme CN212698866U discloses a wooden height ruler for children. Through the support base, the height ruler is inserted into the slot of the fixed block and fixedly connected by fixing bolts; the second groove is longer than the first groove, and the second groove is the same length as the block, so that the block can connect the first groove and the second groove, fix the first height ruler and the second height ruler, keep them vertical, and facilitate measurement; the first height ruler and the second height ruler are rotatably connected by a connecting hinge, and when not in use, they are easy to disassemble, fold and store, which is convenient for use. However, the height ruler can only be folded in the middle, and the volume is still large after folding, and the shrinkage ratio is small. After being disassembled and stored, it needs to be temporarily installed when it is taken out for measurement, and there are many operation steps, which is inconvenient to use.

[0006] The utility model discloses a height measuring device for children, comprising a plurality of nested right-angle U-shaped frames, wherein the nested right-angle U-shaped frames can be locked, slid and stretched. After being fully stretched, a straight rod for locking and sliding is arranged in the top right-angle U-shaped frame, and the front sides of the right-angle U-shaped frame and the straight rod are both provided with size scales, and the values ​​of the size scales increase continuously from top to bottom.

[0007] A vertically connected support plate is provided at the lower end of the right-angle U-shaped frame at the bottom, and a top plate is provided at the upper end of the straight rod, and the support plate and the top plate extend toward the same side.

[0008] As an improvement, inwardly opening slots are provided on both sides of the right-angled U-shaped frame, the upper ends of the slots are sealed, and protrusions are provided on the bottoms of both sides of several right-angled U-shaped frames above the bottom, and protrusions are provided on the bottoms of both sides of the straight rod, and the protrusions can slide in the slots.

[0009] As an improvement, there are four right-angled U-shaped frames, and the right-angled U-shaped frame at the bottom is 20-40 cm high.

[0010] As an improvement, the upper ends of the straight rods and the plurality of right-angle U-shaped frames are flush when they are fully nested and contracted.

[0011] Compared with the prior art, the utility model has the following advantages: the support plate is placed on the floor, the top plate is stretched upward, and then the child stands on the support plate and gently places the top plate on the head. Taking the figure as an example, the maximum value of the lowest value of the size scale of the bottom right-angle U-shaped frame minus the interval value of the overlapping area of ​​the upper right-angle U-shaped frame is the height value of the child. After the measurement is completed, the top plate is naturally lowered to the lowest point, as shown in the figure, and then it can be stored.

[0012] The height measuring device for children has an ingenious structural design and a large shrinkage ratio, and occupies very little space after shrinkage. When taken out to measure the height of a child, no installation is required, and a simple pull-up action is required to achieve measurement. After the measurement is completed, the device can be directly lowered naturally to complete the shrinkage. The operation is very convenient and has high practical value and promotion value.
