Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy engineering surveying equipment, specifically relating to a foldable water conservancy engineering surveying ruler. Background Technology

[0002] Water conservancy encompasses flood control, irrigation, navigation, and other functions that mitigate harm and promote benefits. Its scope includes eight types of engineering projects: flood control, drainage, irrigation, hydraulic power, waterways, water supply, sewage ditches, and port engineering. Hydraulic power refers to water energy utilization, and sewage ditches refer to urban drainage. Later, new aspects of water conservancy were added, such as soil and water conservation, water resource protection, environmental water conservancy, and water conservancy and fisheries. For the sake of survival and development, human society has adopted various measures to control and regulate water and water bodies in nature to prevent floods and droughts. Measuring tools are frequently used in water conservancy projects, and surveying rulers are a common type. Because conventional surveying rulers are too long and inconvenient to carry, folding surveying rulers have gradually emerged.

[0003] Commonly available folding surveying rulers, when unfolded, use positioning slots and positioning blocks to position the ruler and flip ruler as a single unit. However, in practice, when the ruler and flip ruler are unfolded to a certain angle and the positioning block is about to insert into the positioning slot, the positioning block is not perpendicularly aligned with the slot. The function of the positioning slot and positioning block dictates that the positioning block must be inserted into the slot with a tight fit or interference fit. This results in significant wear on the tilted positioning block when inserted. After repeated use, the positioning block or positioning slot may wear down to the point where it can no longer fit together tightly to position the ruler and flip ruler. Consequently, the unfolded surveying ruler can easily be folded backwards, making it very inconvenient to use. Furthermore, in field surveying work, multiple measurement tasks are often performed, requiring operators to frequently change measuring tools, significantly reducing measurement efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a foldable hydraulic engineering surveying ruler, which solves the problem that existing measuring rulers cannot position the ruler plate and the tilting pool after repeated use due to wear of the positioning block.

[0005] The technical solution adopted by this utility model is: a foldable hydraulic engineering surveying ruler, including a first ruler body and a second ruler body. One side of the first ruler body is connected to the second ruler body through a connecting mechanism. The two ends of the first ruler body and the second ruler body that are close to each other are inserted together. The end of the first ruler body that is far away from the second ruler body is connected to a third ruler body.

[0006] The feature of this utility model is that,

[0007] The end of the second ruler near the end of the first ruler is connected to a plug, and the end of the first ruler near the end of the second ruler has a plug hole that matches the plug.

[0008] The connecting mechanism includes a hinge seat, which is connected to one side of the first ruler body. The hinge seat is connected to a connecting block via a pin, and the connecting block is connected to the second ruler body via a sliding assembly.

[0009] The sliding component includes a T-shaped block, which is connected to a connecting block. A T-shaped groove is provided on one side of the second ruler, which is located close to the first ruler. The T-shaped block is slidably connected to the T-shaped groove.

[0010] The first ruler body has a handle connected to the hinge seat on one side, and a magnet is embedded in the handle. The second ruler body has an iron plate embedded in the side with a T-shaped groove, and the magnet and the iron plate are positioned correspondingly.

[0011] The first ruler body has a storage hole, the length of which is not less than the length of the third ruler body. The third ruler body is connected to the end of the first ruler body away from the second ruler body via a shaft.

[0012] An indicator arrow is fixed to the shaft, and the indicator arrow and the handle are located on the same side of the first ruler. A scale line is opened around the shaft on one side of the first ruler.

[0013] The bottom edge of the first ruler has a notch.

[0014] The beneficial effects of this utility model are:

[0015] This utility model relates to a foldable hydraulic engineering surveying ruler. By creating a T-slot on the second ruler body and connecting a T-block to the connecting mechanism for folding and connecting the first and second ruler bodies, the second ruler body can be unfolded with a certain distance from the first ruler body. This allows for the vertical insertion of the insert into the insertion hole, preventing wear on the insertion structure from affecting the stability of the surveying ruler during folding and unfolding, making it very convenient to use. Furthermore, by embedding a rotatable third ruler body within the first ruler body, and by installing and machining indicator arrows and angle scale lines between the first and third ruler bodies, the surveying ruler can not only be folded and used for measuring length but also measure angles, offering rich functionality and wide applicability.

[0066] The working principle of this foldable hydraulic engineering surveying ruler is as follows:

[0067] When the surveying ruler is not in use, such as Figure 5 As shown, the third ruler 9 is stored inside the first ruler 1. The first ruler 1 and the second ruler 2 are folded together by the connecting mechanism 3 and magnetically connected by the magnet 15 and the iron sheet 16. When it is necessary to measure the length, the first ruler 1 and the second ruler 2 are unfolded and pulled away from each other.

Then, the first ruler 1 and the second ruler 2 are brought closer together so that the insert 6 is accurately inserted into the insert hole 7. During this period, the T-shaped block 4 can move inside the T-shaped groove 5 without affecting the connection relationship between the connecting mechanism 3 and the second ruler 2. When it is necessary to measure the angle, the third ruler 9 can be pinched from the notch 13 and rotated out from the storage 8. The first ruler 1 and the third ruler 9 work together to measure the angle. During this period, the specific angle value can be determined by the position of the indicator arrow 11 on the scale line 12.

[0068] This utility model features a foldable hydraulic engineering surveying ruler. By creating a T-slot on the second ruler body and connecting a T-block to the connecting mechanism for folding and connecting the first and second ruler bodies, the second ruler body can be unfolded with a certain distance from the first ruler body. This allows the insert block to be inserted vertically into the insertion hole, preventing wear on the insertion structure from affecting the stability of the surveying ruler when folded and unfolded. It is very convenient to use.
