DETAILED DESCRIPTION

[0019] 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.

[0020] The utility model provides a portable measuring tool, such as Figure 1-Figure 3 As shown, it includes a plurality of foldable height rulers 1, which are hingedly connected by hinges 2 to facilitate the folding and storage of the plurality of foldable height rulers 1. A strip hole 11 is provided on one side of each foldable height ruler 1, and a development measuring ruler 5 is vertically slidably arranged in each foldable height ruler 1. The development measuring ruler 5 includes a tape measure 51. The tape measures 51 on one side of the foldable height rulers 1 of different heights respectively measure different parts, such as chest circumference, waist circumference, head circumference, etc. One end of the tape measure 51 extends out of the strip hole 11, and the other end of the tape measure 51 is connected to a winding sleeve 52. A rotatable shaft 53 is provided inside the foldable height ruler 1, and the winding sleeve 52 is fixedly installed on the top of the shaft 53. A spring spring 55 is installed at the bottom end of the shaft 53 for automatically winding up the tape measure 51 when not in use.

[0021] In this embodiment, a folding positioning plate 4 is installed at the bottom of the folding height ruler 1, a mounting plate 41 is fixed at one end of the folding positioning plate 4, a clamping bolt 42 is installed on the mounting plate 41, the end of the clamping bolt 42 is threaded through the mounting plate 41, a clamping plate 421 is installed at one end of the clamping bolt 42, a positioning column 43 is installed at the other end of the folding positioning plate 4, a fixing plate 6 is installed at one side of the bottom of the folding height ruler 1, the outer end of the positioning column 43 penetrates the fixing plate 6, the outer end of the positioning column 43 is provided with a thread, and a limit nut is installed. When a plurality of folding height rulers 1 are folded together, the clamping bolt 42 is rotated so that the clamping plate 421 is pressed against the side of the plurality of folding height rulers 1, so that the plurality of folding height rulers 1 in the folded state are not easily separated, thereby being convenient to carry.

[0022] Specifically, a foot pedal 3 is installed at the bottom end of the foldable height ruler 1 located on the bottom side. When measuring, the foot pedal 3 is pressed by the foot to keep the foldable height ruler 1 in the unfolded state vertical. In order to ensure that the foldable height ruler 1 is not easy to shake, a magnetic sheet 7 is installed at the end of each foldable height ruler 1. After the foldable height ruler 1 is unfolded, the magnetic sheet 7 will be adsorbed between adjacent foldable height rulers 1 to ensure the straight state of the foldable height ruler 1.

[0023] Furthermore, slide plates 54 are rotatably mounted at the upper and lower ends of the rotating shaft 53, and a slide groove 12 is provided on one inner wall of the foldable height ruler 1. One end of the two slide plates 54 are inserted into the slide groove 12 for sliding connection. By moving the slide plates 54, the growth measuring ruler 5 can be easily moved up and down, so as to be adjusted according to people of different heights. One end of the clockwork spring 55 is fixedly connected to the rotating shaft 53, and the other end is fixedly connected to the slide plate 54 below.

[0024] Furthermore, the foldable height ruler 1 is provided with scale lines from top to bottom, so as to facilitate the measurement of height.

[0025] Furthermore, the measuring tape 51 is made of silicone material to avoid scratches during measurement.

[0026] Furthermore, the top corner of the foldable height ruler 1 is an outwardly protruding arc structure to avoid damage.

[0027] When the portable measuring tool of the utility model is used, first loosen the clamping bolt 42 so that the pressure plate 421 is separated from the side of the folding height ruler 1, and then each folding height ruler 1 is unfolded to an appropriate height one by one. Each folding height ruler is flexibly rotated through the hinge 2, and is magnetically connected to each other through the magnetic sheet 7. A foot pedal 3 is provided at the bottom of the folding height ruler located on the bottom side, and the user steps on the foot pedal to ensure the stability of the overall structure. At the same time, a magnetic sheet 7 is installed at the end of the folding height ruler. When the folding height ruler is unfolded, the magnetic sheet will automatically absorb the adjacent folding height ruler to further enhance the overall stability. The folding height ruler is provided with scale lines from top to bottom in sequence, and the user can directly observe these scale lines to read the height data of the child being measured.

[0028] The user slides the slide plate 54 in the slide groove 12 on the inner wall of the folding height ruler to adjust the growth measuring ruler 5 to a proper position, so that people of different heights can use the growth measuring ruler 5. If it is necessary to measure the size of other body parts such as chest circumference and waist circumference, the user can gently pull out the tape measure 51, one end of which is fixed on the winding sleeve 52, and the other end extends through the bar hole 11. The user wraps the tape measure around the measured part and then reads the data on the tape measure. The tape measure is made of silicone material, which is soft and will not scratch the skin, ensuring the accuracy and safety of the measurement. When the measurement is completed, the user releases the tape measure, and the spring spring 55 will automatically retract the tape measure into the winding sleeve to achieve an automatic storage function.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
