Description

Technical Field

In addition, traditional slope measuring rulers have a relatively simple structural design and lack necessary protective measures, making key components such as the scale plate and suspension rope easily damaged. Furthermore, the support and stabilization mechanisms of traditional slope measuring rulers are not flexible enough to adapt to the measurement needs of different slopes. Therefore, it is particularly important to design a slope measuring ruler that is structurally stable, accurate, easy to carry, and has protective measures. This slope measuring ruler aims to solve the above problems and improve the accuracy and convenience of measurement. Utility Model Content

[0026] Please see Figure 1-4 A slope measuring ruler includes a transparent plate 1, a scale plate 2, a suspension rope 4, a plumb bob 5, a bearing 7, a protective shell 9, and a stabilizing mechanism. The scale plate 2 is fixed in the middle of the side of the transparent plate 1. The bearing 7 is located on the side of the scale plate 2 away from the transparent plate 1. One end of the suspension rope 4 is located below the bearing 7, and the other end of the suspension rope 4 is fixed with the plumb bob 5. The protective shell 9 is provided around the transparent plate 1, and the stabilizing mechanism is located on both sides of the bottom surface of the transparent plate 1.

[0027] The stabilizing mechanism includes support rods 13, fixing blocks 14, connecting blocks 15, and rotating columns 16. The four fixing blocks 14 are fixed to the corners of the bottom two sides of the transparent plate 1, and the four support rods 13 are set on the side of the fixing blocks 14 near the pendant. The end of the support rod 13 near the fixing block 14 is fixed with a connecting block 15. The upper and lower sides of the connecting block 15 are fixed with rotating columns 16, which are inserted into the fixing blocks 14.

[0028] In this embodiment, a U-shaped groove is provided on the side of the fixing block 14 away from the transparent plate 1. Rotation holes corresponding to the rotating column 16 are provided on both sides of the fixing block 14 located in the U-shaped groove. The connecting block 15 is rotatably connected to the U-shaped groove of the fixing block 14 through the rotating column 16. This design not only allows the connecting block 15 to rotate flexibly in the fixing block 14 through the rotating column 16, but also ensures that the support rod 13 can stably support the transparent plate 1 at different angles, thereby improving the applicability and stability of the measuring ruler.

[0029] In this embodiment, an inverted protractor scale is provided on the side of the scale plate 2 away from the transparent plate 1. A fixing post 6 is fixed to the inner ring of the bearing 7. Limiting blocks 3 are fixed to both ends of the fixing post 6. The side of the limiting block 3 closest to the transparent plate 1 is fixed to the center of the scale of the scale plate 2. The combined use of the bearing 7, the fixing post 6 and the limiting block 3 ensures that the suspension rope 4 and the plumb bob 5 can maintain a stable vertical state during the measurement process, and are not affected by the tilt angle of the transparent plate 1, thereby further improving the measurement accuracy.

[0030] In this embodiment, a fixing ring 8 is fixed to the outer side of the outer ring of the bearing 7, and a suspension rope 4 is fixed to the bottom of the arc surface of the fixing ring 8 at the end away from the plumb bob 5. This connection method also facilitates the replacement and maintenance of the suspension rope 4, and improves the durability and practicality of the measuring ruler.

[0031] In this embodiment, sliders 12 are fixed on both sides of the transparent plate 1, and slots 10 are provided inside the bottom surface of the protective shell 9.

[0032] In this embodiment, the protective shell 9 has grooves 11 on both sides inside the slot 10 that correspond to the slider 12. The slider 12 is inserted into the groove 11, and the transparent plate 1 is inserted into the slot 10 of the protective shell 9 through the slider 12. This insertion method also ensures that the transparent plate 1 can be placed inside the protective shell 9 when not in use, preventing damage caused by accidental collision or drop, and extending the service life of the measuring ruler.

[0033] Beneficial effects:

[0034] This slope measuring ruler enhances stability during measurement through the design of a stabilizing mechanism support rod 13, a fixing block 14, a connecting block 15, and a rotating column 16, effectively preventing measurement errors caused by external factors. The combination of the scale plate 2 and the inverted protractor scale makes the reading more intuitive and accurate. The cooperation of the bearing 7, the fixing column 6, and the limiting block 3 ensures the flexible rotation and positioning of the suspension rope 4 and the plumb bob 5. The transparent plate 1 provides good protection for the internal components by inserting the slider 12 into the groove 11 of the protective shell 9, thus extending its service life.

[0035] Working principle:

[0036] When using the equipment, first pull it out of the slot 10 of the protective shell 9. Then, use the support rod 13 in the stabilizing mechanism to rotate the rotating column 16 on the connecting block 15 in the U-shaped groove and rotating hole of the fixed block 14 to adjust the angle, so as to stabilize the equipment on the slope to be measured. During measurement, one end of the suspension rope 4 is fixed to the fixing ring 8 on the outer side of the outer ring of the bearing 7, and the other end is connected to the lead weight 5. The lead weight 5 hangs down naturally, and the slope value can be obtained by directly reading the corresponding scale.
