Description

A surveying ruler for geological mapping Technical Field

[0001] This utility model relates to the field of geological surveying devices, and in particular to a surveying ruler for geological surveying. Background Technology

[0002] Geological surveying is the work of measuring and depicting the spatial location and geometric shape of geological bodies and phenomena using the principles, methods and instruments of surveying. It is an important foundation of geological work, providing basic geographic information and data for geological research, mineral exploration and engineering construction, and has important guiding significance for geological research, resource development and environmental protection. The surveying ruler is an important tool used in geological surveying to measure and draw geological maps, mainly used to determine the location and accuracy of geological points, geological boundaries and geological profiles.

[0003] The existing patent "A Geological Surveying Ruler (Publication No.: CN221445004U)" states that "This utility model belongs to the field of geological surveying equipment technology, specifically a geological surveying ruler, including a ruler body, which comprises several ruler bodies that are nested and slidably connected in sequence. The surface of each ruler body is provided with length scale lines. This utility model allows for multi-level adjustment of the overall surveying length of the ruler body by pushing the ruler bodies to slide. The locking plate is engaged with the sliding groove by the elastic force of a spring, thereby fixing the ruler bodies in place. The required geological surveying length can be read by adding the length scale lines. Compared with the prior art, this utility model can stably adjust the overall length of the ruler, making it convenient to store and carry during geological surveying and allowing for flexible adjustment of the surveying length."

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: In the above-mentioned patent, the angle of geological survey is drawn by measuring arm one and measuring arm two. However, the measuring arms are often relatively short. When measuring arm two is rotated to align with the target, the short measuring arm two may not be able to accurately align with the target, which may lead to a large error in the survey angle. In addition, after measuring arm two is rotated to a certain angle, the stability of the measuring arm is only ensured by the damping ring. This method is often not stable enough. The measuring arm may slide down slightly under the action of gravity, which may affect the accuracy of the measurement data.

[0005] Therefore, those skilled in the art have provided a surveying ruler for geological mapping to solve the problems mentioned in the background art. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a geological surveying ruler that can ensure both the accuracy of the measuring arm alignment and the stability of the measuring arm.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Referring to Figure 1, one embodiment of this utility model is provided: a geological surveying ruler, including a main body 1, a surveying mechanism 2 is provided at the upper end of the main body 1, and a stabilizing mechanism 3 is provided at the front end of the surveying mechanism 2;

[0031] Specifically, the main body mechanism 1 is the main part of the measuring ruler and is used for length measurement, the measuring mechanism 2 is mainly used for angle measurement, and the stabilizing mechanism 3 can ensure the stability of the measuring arm during the measurement process.

[0032] Referring to Figure 2, the main body mechanism 1 includes a main scale 101, a secondary scale 102 is slidably sleeved inside the main scale 101, a plurality of slots 103 are provided at the rear end of the secondary scale 102, and a card plate 104 is slidably arranged inside the main scale 101.

[0033] Both the main scale 101 and the auxiliary scale 102 have length scale lines at their front ends. The auxiliary scale 102 is slidably disposed inside the main scale 101 along the vertical direction. The locking plate 104 is slidably disposed inside the main scale 101 along the horizontal direction. The front end of the locking plate 104 has multiple protrusions, which are respectively locked into multiple slots 103.

[0034] Specifically, both the main scale 101 and the auxiliary scale 102 are used for length measurement. They are connected together by a sliding sleeve. The auxiliary scale 102 can slide vertically inside the main scale 101 to form a telescopic structure that can adjust the length. The locking plate 104 can slide back and forth inside the main scale 101. When the locking plate 104 slides forward, its front end engages with the locking groove 103 to lock the auxiliary scale 102, ensuring relative stability between the main scale 101 and the auxiliary scale 102. When the locking plate 104 slides backward, it disengages from the locking groove 103, releasing the locking of the auxiliary scale 102, allowing the auxiliary scale 102 to slide smoothly up and down.

[0035] Referring to Figures 4 and 5, the surveying mechanism 2 includes a fixed block 201, a base plate 202, and a ring 206. A fixed shaft 203 is fixedly installed at the front end of the base plate 202 near the middle position. A first measuring arm 204 is fixedly sleeved on the outer surface of the fixed shaft 203 near the rear end. A second measuring arm 205 is rotatably sleeved on the outer surface of the fixed shaft 203 near the front end. A transparent frame 207 is fixedly sleeved in the middle of the ring 206. An extension arm 208 is fixedly installed on the outer surface of the ring 206 near the lower end.

[0036] The fixing block 201 is fixedly installed on the upper end of the main scale 101. The rear end of the ring 206 is rotatably sleeved on the front end of the base plate 202. The base plate 202 is fixedly sleeved on the front end of the fixing block 201. Angle scale lines are provided on the front end of the base plate 202. The middle position of the rear end of the transparent frame 207 is fixedly connected to the front end of the second measuring arm 205. The second measuring arm 205 and the extension arm 208 are aligned in the vertical direction.

[0037] Specifically, the fixing block 201 fixes the surveying mechanism 2 and the main body mechanism 1 together. The base plate 202, the ring 206, and the transparent frame 207 can form a closed structure. The base plate 202 is near the rear end and has a fixing effect on the internal structure. The ring 206 and the transparent frame 207 are near the front end and are equivalent to a cover with a sealing function. The ring 206 can rotate, and the state of the internal measuring arm can be observed through the transparent frame 207. The fixing shaft 203 is located at the center of the base plate 202. The ring 206 and the second... All measuring arms 205 can rotate around the fixed axis 203. The first measuring arm 204 is fixed and its upper end is fixedly sleeved on the fixed axis 203. The first measuring arm 204 always remains vertical. The second measuring arm 205 is fixedly connected to the transparent frame 207 and can rotate with the rotation of the ring 206. The extension arm 208 and the second measuring arm 205 are kept on the same straight line. The extension arm 208 can better align with the target, reduce the error of manual alignment, and ensure the accuracy of the measurement data.

[0038] Referring to Figures 3 and 4, the stabilizing mechanism 3 includes an arc-shaped slide rail 301, an arc-shaped slider 302, and a threaded block 304. Arc-shaped grooves 303 are provided on both sides of the inner surface of the arc-shaped slide rail 301. Limiting blocks 305 are fixedly provided near the rear end of the threaded block 304 on both sides. A bolt 306 is threaded in the middle of the threaded block 304.

[0039] The arc-shaped slide rail 301 is fixedly installed at the front end of the fixed block 201. The two sides of the threaded block 304 are slidably installed in the two arc-shaped slide grooves 303 respectively. The arc-shaped slider 302 is slidably installed in the arc-shaped slide rail 301. The front end of the arc-shaped slider 302 is fixedly connected to the rear end of the extension arm 208 near the lower end. The outer surface of the bolt 306 near the front end is rotatably sleeved in the arc-shaped slider 302. The outer surface of the bolt 306 near the middle is sleeved in the arc-shaped slider 302.

[0040] Specifically, the arc-shaped slide rail 301 is a semi-circular slide rail, and the arc-shaped slider 302 is a quarter-arc slider. The arc-shaped slider 302 can slide within the arc-shaped slide rail 301. The arc-shaped groove 303 restricts the threaded block 304 to a vertical plane. The threaded block 304 can slide along the arc-shaped groove 303, but cannot move back and forth. The limiting block 305 restricts the threaded block 304, preventing it from rotating, thus ensuring relative movement between the bolt 306 and the threaded block 304. Rotating the bolt 306... The threaded action allows the bolt 306 to move back and forth. When the bolt 306 moves to a position near the rear end, it tightly fixes the arc-shaped slider 302 in the arc-shaped slide rail 301. At this time, the arc-shaped slider 302 cannot slide along the arc-shaped slide rail 301 and is in a relatively stable stationary state. When the bolt 306 moves to a position near the front end, it does not exert much pressure on the arc-shaped slider 302. At this time, the arc-shaped slider 302 can slide freely along the arc-shaped slide rail 301, which facilitates the angle adjustment of the second measuring arm 205 and the extension arm 208.

[0041] Working principle: When using this measuring ruler to measure length, slide the locking plate 104 backward to disengage the locking plate 104 from the locking slot 103, slide the auxiliary ruler 102 up and down until the auxiliary ruler 102 reaches the appropriate position, and then slide the locking plate 104 forward to engage the front end of the locking plate 104 into the locking slot 103 to lock the auxiliary ruler 102 and complete the length measurement.

[0042] When using this measuring ruler to measure angles, rotating the bolt 306, under the constraint of the limiting block 305 and the arc-shaped slide 303, causes relative movement between the bolt 306 and the threaded block 304. Under the action of the thread, the bolt 306 moves forward, releasing the bolt 306 from locking the arc-shaped slider 302. Holding the extension arm 208 and pulling it to rotate around the fixed axis 203, the ring 206, the transparent frame 207, and the second measuring arm 205 rotate synchronously until the extension arm 208 is aligned with the target. At this point, the angle between the second measuring arm 205 and the first measuring arm 204 can be read through the angle scale, completing the angle measurement.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
