Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and in particular to an adjustable measuring rod. Background Technology

[0002] A surveying benchmark is a common measuring tool that plays an important role in engineering surveying. As a reference point for measurement, a surveying benchmark must possess a certain degree of stability to ensure the accuracy and reliability of the measurements. Furthermore, after the measurement is completed, the data must be verified to guarantee its accuracy.

[0003] Existing measuring rods are mostly held manually to maintain perpendicularity to the ground, and additional measuring rods are needed after measurement to verify the data. This process is cumbersome, wastes manpower, and introduces measurement errors. While existing measuring rods with fixed legs have a fixed structure, they only provide support and lack adjustment capabilities. This makes them unsuitable for uneven ground, preventing angle adjustments and leading to significant measurement deviations, greatly affecting the accuracy of the data. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable measuring rod to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention can adopt the following technical solution:

[0006] The adjustable measuring rod of this utility model includes a rod body and a support unit for supporting the rod body, the support unit comprising:

[0007] The first inclined support leg has a connector at its inclined upper end, and the connector has a U-shaped groove.

[0008] The second inclined support leg consists of two sets, which are rotatably connected to the left and right sides of the connector.

[0009] The adjusting ball is fitted into the U-shaped slot, and a through tube for inserting the marker body is provided on it;

[0010] The limiting clamp is clamped onto the main body of the marker pole.

[0011] Furthermore, the lower end of the pole body has a conical head, which facilitates stable support on the ground.

[0012] Furthermore, the upper inclined end of the second inclined leg is provided with a snap-fit ​​ball head, and the snap-fit ​​ball head is provided with an annular snap-fit ​​groove along the circumferential direction on the side near the second inclined leg. The outer side wall of the connector is provided with an insertion hole adapted to the snap-fit ​​ball head, so as to easily realize the stable connection between the second inclined leg and the connector and realize the rotation adjustment of the second inclined leg.

[0013] Furthermore, the left and right walls of the U-shaped slot are symmetrically provided with arc-shaped concave surfaces adapted to clamp the adjusting ball. Rubber anti-slip pads or silicone anti-slip pads are attached to the arc-shaped concave surfaces to ensure that the adjusting ball can be firmly clamped in the U-shaped slot and to ensure that the adjusting ball can rotate to adjust the angle.

[0014] Furthermore, the adjusting ball is equipped with a level, which allows for easy observation of whether the target rod inserted into the tube is vertical.

[0015] Furthermore, an auxiliary clamp is connected to the limiting clamp via a connecting cross brace. The axial direction of the clamping part of the auxiliary clamp is parallel to the axial direction of the clamping part of the limiting clamp, which facilitates clamping another benchmark for verification.

[0016] The advantages of this utility model are its simple structure, easy operation, and convenient disassembly and storage. The first inclined leg and two second inclined legs together form a three-point support, ensuring the stability of the marker body inserted into the adjusting ball, eliminating the need for manual support. Simultaneously, the adjusting ball can be used to change the angle of the marker body, ensuring it remains vertical and meeting the requirement of perpendicularity to the ground in engineering surveying. Furthermore, the limiting clamps can be used to position the height of the marker body, making its height adjustable and further improving its adaptability in engineering surveying, ensuring the accuracy of measurement data.

[0023] 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.

[0024] like Figure 1-6 As shown, the adjustable measuring pole of this utility model includes a pole body 1, which serves as a measuring reference in engineering surveying, and a support unit for supporting and fixing the pole body 1. The pole body 1 is a straight pole structure with a conical head 2 at its lower end for easy and stable insertion into the ground. The support unit includes a first inclined leg 3, a second inclined leg 4, an adjusting ball 5, and a limiting clamp 6.

[0025] Specifically, a connector 7 is provided at the inclined upper end of the first inclined support leg 3. The connector 7 has a U-shaped groove 8. Preferably, the groove opening of the U-shaped groove 8 is exactly opposite to the downward inclined direction of the first inclined support leg 3.

[0026] The second inclined support leg 4 consists of two sets, which are rotatably connected to the left and right sides of the connector 7, thus forming a stable three-point support structure together with the first inclined support leg 3, ensuring the stability of the support. To achieve the rotatable connection between the second inclined support leg 4 and the connector 7, a snap-fit ​​ball head 9 can be provided at the inclined upper end of the second inclined support leg 4, and an annular snap-fit ​​groove 10 is opened circumferentially on the side of the snap-fit ​​ball head 9 near the second inclined support leg 4. At this time, an insertion hole 11 adapted to the snap-fit ​​ball head 9 is opened on the outer wall of the connector 7. The insertion hole 11 is a spherical cavity, and the opening of the spherical cavity is also turned inward to form a retaining ring that can be fitted into the annular snap-fit ​​groove 10, easily achieving a stable connection between the second inclined support leg 4 and the connector 7, and enabling the rotational adjustment of the second inclined support leg 4.

[0027] The adjusting ball 5 is a sphere with a diameter larger than the width of the U-shaped groove 8. Symmetrically arranged on the left and right walls of the U-shaped groove 8 are arc-shaped concave surfaces 12 designed to accommodate and clamp the adjusting ball 5. A rubber or silicone anti-slip pad is attached to each arc-shaped concave surface 12 to ensure the adjusting ball 5 is securely clamped between the two arc-shaped concave surfaces 12, preventing it from falling out of the U-shaped groove 8 and allowing it to rotate within the U-shaped groove 8. Additionally, a through-tube 13 passes through the center of the adjusting ball 5. The inner side of the through-tube 13 is a vertically penetrating cavity, the diameter of which should match the diameter of the marker body 1. This allows the marker body 1 to be inserted into the through-tube 13, and the rotation of the adjusting ball 5 changes the angle of the marker body 1, ensuring it remains vertical. Furthermore, to facilitate observation of whether the target body 1 is vertical, a level 14 can be installed on the adjusting ball 5. The level 14 can be a circular horizontal tube filled halfway with measuring liquid, and a positioning line 15 perpendicular to the axis of the through tube 13 is marked in the middle of the circular horizontal tube. When adjusting the angle of the target body 1, the verticality of the target body 1 can be determined by whether the liquid level in the circular horizontal tube coincides with the positioning line 15. Of course, the level 14 can also be a cylindrical horizontal tube, in which case the axis of the cylindrical horizontal tube should be perpendicular to the axis of the through tube 13. When adjusting the angle of the target body 1, as long as the cylindrical horizontal tube remains horizontal, it proves that the target body 1 inserted in the through tube 13 is vertical, easily determining whether the target body 1 has been adjusted to meet the engineering surveying requirements.

[0028] The limiting clamp 6 is a clamp with a C-shaped cross-section. The inner side of the clamp is the clamping part, and its diameter should be slightly smaller than the diameter of the pole body 1. A pair of clamping ear plates with bolt holes are provided on both sides of the opening of the clamp. By fitting the clamp onto the pole body 1 and passing the bolt assembly through the bolt holes on the clamping ear plates, the two clamping ear plates are clamped together by the bolt assembly, thereby fixing the entire limiting clamp 6 onto the pole body 1, forming a limiting component that is blocked above the through pipe 13, and positioning the height of the pole body 1. In addition, a horizontally extending connecting cross brace 16 can be provided on the outer wall of the limiting clamp 6, and an auxiliary clamp 17 with the same structure as the limiting clamp 6 can be provided at the outer end of the connecting cross brace 16. The auxiliary clamp 17 is used to clamp another auxiliary rod when the engineering survey is completed and verified. The axial direction of the inner clamping part of the auxiliary clamp 17 should be parallel to the axial direction of the inner clamping part of the limiting clamp 6, so that the auxiliary rod clamped therein can be kept parallel to the measuring rod 1.

[0029] During engineering surveying, firstly, the two second inclined legs 4 are installed on the connector 7 at the upper end of the first inclined leg 3, forming a three-point support structure. The angle of the two second inclined legs 4 is adjusted according to the terrain characteristics to ensure stable support on the ground. Then, the marker body 1 is inserted into the tube 13 of the adjusting ball 5, which is clamped on the connector 7. The angle of the marker body 1 is adjusted according to the level 14 on the adjusting ball 5 to keep the marker body 1 vertical. Finally, the conical head 2 at the lower end of the marker body 1 is inserted into the ground for fixation. The marker body 1 is then adjusted according to the needs of the engineering surveying. After the vertical height of the pole body 1 is adjusted to the correct position, the limiting clamp 6 is fitted onto the pole body 1, and the limiting clamp 6 is clamped precisely at the point where it contacts the upper end of the through pipe 13, ensuring that the height of the pole body 1 is fixed. In this way, the pole body 1 can be used as a measurement reference for engineering surveying, ensuring that the pole body 1 can maintain stable vertical support and ensuring support stability. There is no need to waste manpower to hold the pole body 1, which meets the requirement that the pole is perpendicular to the ground in engineering surveying, improves the adaptability of the pole body 1 in engineering surveying, and ensures the accuracy of measurement data.

[0030] After the engineering survey is completed, further verification work can be carried out. During verification, the auxiliary rod for verification is inserted into the auxiliary clamp 17. The vertical distance of the auxiliary rod is adjusted by the auxiliary clamp 17, thereby using the principle of the three points of human eye, rod body 1 and auxiliary rod 17 in a straight line to verify the measurement data.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
