Description

Technical Field

[0001] The utility model relates to the technical field of land measurement, and particularly relates to a new positioning rod for land measurement. Background Technique

[0002] The positioning rod for land measurement belongs to the field of land management. Since land management is a comprehensive measure taken by the state to adjust land relations, organize and supervise land development and utilization, protect and rationally utilize land resources, land measurement is required when using land resources. Land measurement is the work of measuring and mapping the quantity, distribution, topography and other characteristics of various lands by using surveying and remote sensing technology methods, including topographic survey, cadastral survey, land leveling survey, land use status survey, investigation of reserve resources such as barren mountains and wastelands, etc. A positioning rod is used during land measurement to locate the measurement range and can also be used to measure the height and depth of some lands.

[0003] To improve the existing positioning rod for land measurement, during the installation process, the positioning rod needs to be inserted into the soil. When encountering a geological environment with a lot of stones and hard soil, the positioning rod cannot be installed and fixed, which is not convenient for the use of the positioning rod. And when conducting land measurement, the inclination of the ground cannot be detected simultaneously according to the placement position of the positioning rod, and other instruments are required for measurement, resulting in poor practicability of the positioning rod. The patent with the application number 202222519246.2 in the disclosed technology can be applied, including a base, a screw post is arranged on the outer side of the base, an adjustment groove is opened on the periphery of the base, and a support arm is movably connected to the inner side of the adjustment groove through the screw post, and a through hole is opened on one side of the support arm.

[0004] Although the angle of the four support arms can be adjusted to make it fit and fully contact with the uneven ground, so that the support rod can still be set in a vertical state when the ground is uneven, in actual use, its adaptation range is relatively limited, and it can only meet the laying use of the slope-type ground. However, the surface shape of the outdoor measured land is diverse. When the ground is uneven where the positioning rod needs to be set up, the contact range between the lower surface of the support arm that plays a supporting role and the uneven ground is relatively limited, and it is difficult to keep the upper positioning rod in a stable state.

However, the shapes of the outdoor land surface are diverse. When a positioning rod needs to be set up and the ground is uneven, the contact range between the lower surface of the support arm that plays a supporting role and the uneven ground is relatively limited, and it is very difficult to keep the upper positioning rod in a stable state, and the practical performance needs to be strengthened.

[0022] Please refer to Figures 1-4 For this utility model, a technical solution is provided: a new type of positioning rod for land measurement, including a vertical cylinder 1. Inside the vertical cylinder 1, there is a vertical rod 2. The outer wall of the vertical rod 2 is in clearance fit with the inner wall of the vertical cylinder 1. At the front top end of the outer wall of the vertical cylinder 1, there is a bolt 3 threadedly connected. A part of the bolt 3 penetrates through the vertical cylinder 1 and abuts against the vertical rod 2. On both sides of the outer wall of the vertical rod 2, there are vertically arranged scales 4. The user can judge the top height of the vertical rod 2 through the scales 4 and the values at the top end of the vertical cylinder 1. At both ends of the upper surface of the vertical rod 2, there are fixedly connected support rods 5. At the top ends of the support rods 5, there is a support plate 6 fixedly connected. On the upper surface of the support plate 6, there is a spirit level 7. By observing the spirit level 7, it is convenient to place the cavity plate 801 horizontally downward. At the bottom end of the vertical cylinder 1, there is a support assembly 8. The support assembly 8 includes a cavity plate 801, a vertical cylinder 802, a compression spring 803, a vertical rod 804, a stopper 805, a cross plate 806, a connecting rod 807, a sliding rod 808, a lead screw 809, and a knob 810. The cavity plate 801 is fixedly connected to the bottom end of the vertical cylinder 1. On the upper surface of the cavity plate 801, there are evenly fixedly connected multiple vertical cylinders 802. At the top end inside the vertical cylinder 802, there is a compression spring 803. The coefficient of the compression spring 803 is 0.05 - 0.5 N / CM. The bottom end of the compression spring 803 is fixedly connected to a vertical rod 804. A part of the vertical rod 804 penetrates through the cavity plate 801. The outer wall of the vertical rod 804 is in clearance fit with the penetration surface of the cavity plate 801. In front of the outer wall of the vertical rod 804, there is a stopper 805. Multiple stoppers 805 are all distributed inside the cavity plate 801. At the front end of the front side of the stopper 805, there is a cross plate 806 fixedly connected. Between multiple cross plates 806, there are fixedly connected through a connecting rod 807. On both sides inside the cavity plate 801, there are fixedly connected sliding rods 808. The sliding rods 808 penetrate through the cross plate 806. The outer wall of the sliding rod 808 is in clearance fit with the penetration surface of the cross plate 806. At the center of the front surface of the front cross plate 806, there is a lead screw 809 rotatably connected. The lead screw 809 is rotatably connected to the cross plate 806 through a ball bearing. A part of the lead screw 809 penetrates through the cavity plate 801. The outer wall of the lead screw 809 is threadedly connected to the penetration surface of the cavity plate 801. At the front end of the front side of the lead screw 809, there is a knob 810. Vertically at the center of the front side of the outer wall of the vertical rod 2, there is a groove pattern 9. The groove pattern 9 abuts against the inner end of the bolt 3. The groove pattern 9 can enhance the friction force at the abutting place between the bolt 3 and the outer wall of the vertical rod 2, facilitating the vertical rod 2 to maintain a stable state. The rear surface of the stopper 805 is an arc structure, which can facilitate the stopper 805 to fully abut against the outer wall of the vertical rod 804. A square rod 10 is inserted into the top end of the vertical rod 804. The outer wall of the square rod 10 is in clearance fit with the inner wall of the vertical rod 804, which can improve the stability when the vertical rod 804 slides up and down. The top end of the square rod 10 is fixedly connected to the contact surface of the vertical cylinder 802. The distance between the square rod 10 and the inner circle of the compression spring 803 is 5 - 10 mm, facilitating the compression and rebound of the compression spring 803 to proceed smoothly.

[0023] New positioning rod for land survey. During use, the operator first places the cavity plate 801 above the land where the positioning rod needs to be set up. If the land surface is uneven during this process, when keeping the surface of the cavity plate 801 horizontal and placing it towards the ground, the bottoms of multiple vertical rods 804 below the cavity plate 801 will successively contact and press tightly against the uneven ground surface. During this period, keep the upper surface of the cavity plate 801 horizontal and apply sufficient downward force to the cavity plate 801 to ensure that the bottoms of multiple vertical rods 804 can all contact and press tightly against the ground below. Then, rotate the bolt 3 clockwise to make the abutting block 805 press tightly against the outer wall of the vertical rod 804, thus completing the setup of the positioning rod 2 that can play a positioning role. During this process, because multiple vertical rods 804 can slide upward to different degrees according to the unevenness of the land surface, the bottoms of multiple vertical rods 804 will all contact the land surface. The contact range between the bottoms of the vertical rods 804 that play a supporting role and the uneven ground surface is relatively dense, which can stably support the cavity plate 801 and the positioning rod 2 horizontally, and the practical performance is enhanced.
