Abstract

This utility model discloses a verticality measuring ruler for building engineering, relating to the field of measuring ruler technology. Its key technical features include a ruler body comprising a first ruler rod and a second ruler rod. The upper end of the first ruler rod and the lower end of the second ruler rod are rotatably connected via a rotating shaft. A locking mechanism is provided between the first and second ruler rods. During use, rotating the second and first ruler rods makes the ruler body vertical. During this process, under the action of a spring, a limiting tooth block is pushed to engage with a slot on the surface of the insertion plate, thus firmly connecting the first and second ruler rods together and preventing bending between them. This provides strong stability. During measurement, under the gravity of a lead block, when the wall is not vertical, the vertical gravity of the lead block causes the pointer to point to the corresponding sector scale. The verticality of the wall can then be measured using the sector scale indicated by the pointer. This method is convenient to operate and offers high accuracy.

Description

Technical Field

[0001] This utility model relates to the field of measuring ruler technology, specifically a verticality measuring ruler for building engineering. Background Technology

[0002] In construction engineering, people need to use a verticality measuring ruler for inspection. The verticality measuring ruler can detect the verticality, horizontality and flatness of an object, which plays a great role in construction.

[0003] Patent document CN217900721U discloses a verticality measuring ruler for building engineering. This utility model provides a verticality measuring ruler for building engineering with a relatively high length, thus offering a large measuring range. The ruler includes a support base, suction cups, ball valves, fixing frames, a ruler, fixing rods, and a level. Suction cups are symmetrically arranged on both sides of the support base, and each suction cup has a slidably mounted ball valve on its upper part. Fixing frames are symmetrically welded to the top center of the support base, and a ruler capable of measurement is located in the top center of the support base, connected to two fixing frames. Fixing rods are symmetrically arranged vertically in the middle of the ruler, and a level is connected between the two fixing rods. This utility model allows for increasing the measuring height by rotating the ruler, and avoids the inconvenience of carrying an excessively tall measuring ruler, making it more convenient and efficient.

[0004] In actual use, the above solution has the drawbacks caused by the support base and suction cup, which prevent the measuring ruler from getting close to the wall for measurement. The large distance between the measuring ruler and the wall can affect the accuracy of subsequent verticality testing. In addition, the lack of a locking mechanism at the bend between the two rulers makes it easy for the upper ruler to bend after being straightened, resulting in poor stability. Utility Model Content

[0033] Both the first measuring rod 101 and the second measuring rod 102 are made of stainless steel. A support plate 14 is fixedly installed at the lower end of the first measuring rod 101. The support plate 14 enables the first measuring rod 101 to be stably in contact with the ground, which is convenient for measurement.

[0034] The verticality measuring mechanism includes a mounting frame 2 fixedly installed on the front of the first ruler 101. A connecting rod is fixedly installed on the inner rear wall of the mounting frame 2. A sleeve 3 is rotatably connected to the surface of the connecting rod through a bearing. Symmetrical pointers 4 and lead blocks 5 are fixedly installed on the surface of the sleeve 3. A sector-shaped scale 6 corresponding to the position of the pointers 4 is provided on the inner rear wall of the mounting frame 2.

[0035] Furthermore, the locking mechanism includes an insert plate 7 fixedly installed on the upper end of the first ruler 101, and a slot adapted to the insert plate 7 at the lower end of the second ruler 102. A limiting groove is provided on the inner wall of the right side of the slot, and a spring 8 is fixedly connected to the inner wall of the limiting groove. A limiting tooth block 9 is fixedly installed on the end of the spring 8 away from the inner wall of the limiting groove. A slot adapted to the limiting tooth block 9 is provided on the surface of the insert plate 7. Through the setting of the limiting tooth block 9 and the insert plate 7, the first ruler 101 and the second ruler 102 can be firmly spliced ​​together to avoid bending.

[0036] The back of the second ruler 102 is provided with a sliding strip opening that extends into the limiting groove. The back of the limiting tooth block 9 is fixedly connected to the push rod 10 through the sliding strip opening. The front of the limiting tooth block 9 is provided with a guide slider. The inner front wall of the limiting groove is provided with a guide groove for the guide slider to slide. Under the guidance of the guide slider, the limiting tooth block 9 can smoothly slide in the limiting groove.

[0037] Furthermore, after the first ruler 101 and the second ruler 102 are vertically aligned, their right side is flat and level. A level bubble 11 is embedded on the left side surface of the first ruler 101. By setting the level bubble 11, the ruler 1 can be placed flat on the ground, and the level and flatness of the ground can be measured by the level bubble 11.

[0038] Furthermore, a storage groove is provided on the right side surface of the second ruler 102.

[0039] The front of the display pole 12, the first ruler pole 101 and the second ruler pole 102 are all equipped with measuring scale bars. The height and length of the building can be measured by setting the measuring scale bars.

[0040] In practical use, the working principle of this utility model is as follows:

[0041] Before use: Rotate the second ruler 102 and the first ruler 101 to make the ruler body 1 vertical. During this process, the insert plate 7 of the first ruler 101 is inserted into the slot of the second ruler 102. Under the action of the spring 8, the limiting tooth block 9 is pushed out of the limiting groove until the limiting tooth block 9 engages with the slot on the surface of the insert plate 7. This will firmly connect the first ruler 101 and the second ruler 102 together. At this time, the verticality of the wall can be measured by the vertical ruler body 1. During measurement, the ruler body 1 is placed against the wall. Under the weight of the lead block 5, when the wall is not vertical, the verticality of the lead block 5 will be affected. Gravity drives pointer 4 to point to the corresponding sector scale 6. At this point, the verticality of the wall can be checked by using sector scale 6 pointed to by pointer 4. Meanwhile, the ruler 1 is placed flat on the ground. By observing the spirit level 11, the levelness and flatness of the ground can be measured. Loosen the nut on the surface of screw 13. Without the nut restricting it, pull the extension rod 12 out of the storage slot. After it is fully extended, tighten the nut on the surface of screw 13. By setting the extension rod 12, the overall length of the ruler 1 can be increased, enabling it to measure longer and taller buildings.

[0042] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
