[0002] A ruler is a tool, also known as a measuring stick or measuring tool, which is mainly used to measure the size, distance or angle of an object. There are many types of rulers, and there are various types of designs according to different measurement needs and accuracy requirements. The scales on the ruler are usually marked with standard units of measurement (such as centimeters, meters, millimeters, inches, etc.) to facilitate users to make accurate measurements. In daily life, study, scientific research, industrial manufacturing and other fields, rulers are indispensable tools.

[0003] At present, most of the existing traditional measuring rulers are long and rigid, which makes it inconvenient to carry and store, especially in situations where the measuring ruler needs to be frequently carried or used (such as outdoor measurement, construction site, etc.). At the same time, the existing measuring ruler is not convenient to adjust the length and angle according to needs, and cannot adapt to different measurement needs. It is also inconvenient to better complete the measurement task, resulting in a decrease in the practicality of the measuring ruler. Therefore, we propose a measuring ruler with a folding function to solve the above problems. Utility Model Content

[0030] Embodiment 2

[0031] Reference Figure 1-5 A measuring ruler with a folding function, the adjusting component includes a dial plate 4 arranged on the top of two symmetrically arranged limit grooves, the bottom of the two dial plates 4 are fixedly connected with a limit block 5 adapted to the limit groove, the bottom of the limit block 5 is fixedly installed with a rack 6, one side of the rack 6 is connected with a gear 8 through a card tooth meshing, and the inside of the gear 8 is socketed with the outside of the rotating rod 7.

[0032] The adjustment component also includes an installation box 11 arranged in the installation groove, and a slide groove is opened on the top of the installation box 11. Two sliders 12 are slidably connected at the top of the installation box 11 and located in the slide groove. A damping rod 13 is fixedly installed on one side of the slider 12, and the other end of the damping rod 13 is fixedly installed on the inner wall of one side of the slide groove. The top of the slider 12 is fixedly connected to the bottom of the rack 6.

[0034] According to the above embodiment, it can be known that: the personnel move the paddle plates 4 closer to each other, and then drive the rack 6 to move through the limit block 5, so that the teeth of the rack 6 are separated from the teeth of the gear 8. At this time, the rack 6 will drive the bottom slider 12 to move in the slide groove and squeeze the damping rod 13 and the spring 14. The personnel rotate the second scale plate 2 through the rotating rod 7 to extend out of the bottom of the first scale plate 1. When it is rotated and folded to the required position, the paddle plates 4 are released to make the spring 14 lose the squeezing force and push the slider 12 back to its original position due to elastic recovery. The slider 12 then drives the rack 6 back to its original position and makes the teeth of the rack 6 mesh with the teeth of the gear 8. Then, by blocking the gear 8, the rotating rod 7 cannot drive the second scale plate 2 to rotate. The personnel can use the second scale plate 2 to measure, thereby achieving the effect of convenient storage and extension of the scale plate, thereby improving the practicality of the measuring ruler.

[0035] Embodiment 3

[0036] Reference Figure 1-5 , a measuring ruler with a folding function, wherein two dial plates 4 are fixedly installed with soft pads on the sides away from each other.

[0037] The top of the first scale plate 1 and the tops of the two second scale plates 2 are both equipped with scales.

[0038] According to the above embodiments, the soft cushion is provided so that it is soft and comfortable for people to move the dial plate 4, and it also prevents people's fingers from slipping when moving the dial plate. The scale is provided so that people can use the measuring ruler to measure by observing the scale.

[0039] In summary:

[0040] By moving the paddle plates 4 closer to each other, the rack 6 is driven to move through the limit block 5, so that the teeth of the rack 6 are separated from the teeth of the gear 8. At this time, the rack 6 will drive the bottom slider 12 to move in the slide groove and squeeze the damping rod 13 and the spring 14. The personnel rotate the second scale plate 2 through the rotating rod 7 to extend out of the bottom of the first scale plate 1. When it is rotated and folded to the required position, the paddle plates 4 are released to make the spring 14 lose the squeezing force and push the slider 12 back under the elastic recovery. The slider 12 then drives the rack 6 back and makes the teeth of the rack 6 mesh with the teeth of the gear 8. Then, by blocking the gear 8, the rotating rod 7 cannot drive the second scale plate 2 to rotate. The personnel can use the second scale plate 2 to measure, thereby achieving the effect of convenient storage and extension of the scale plate, thereby improving the practicality of the measuring ruler.
