Description

Technical Field

[0001] The utility model relates to the technical field of land surveying and mapping, in particular to a portable land surveying and mapping level. Background Technique

[0002] A land surveying and mapping level is an instrument for establishing a horizontal line of sight to measure the height difference between two points on the ground. Its principle is to measure the height difference between ground points according to the principle of leveling. The main components include a telescope, a tubular level (or compensator), a vertical axis, a base, a foot screw, and a bracket. It is divided into a tilting level, an automatic level, a laser level, and a digital level (also known as an electronic level) according to its structure, and into a precise level and an ordinary level according to its accuracy.

[0003] For a surveying and mapping level, including a level body, a tripod, a placement platform, etc., the bottom ends of the triangular brackets under the existing land surveying and mapping levels are all provided with pointed tips. The exposed diameter of the pointed tips of the existing triangular brackets is somewhat dangerous and can easily stab people, vehicles, or other objects. Therefore, it is very inconvenient for users to carry the existing land surveying and mapping levels. Content of the Utility Model

[0004] The purpose of the utility model is to provide a portable land surveying and mapping level to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A portable land surveying and mapping level, including a mounting base, a level, a support frame, and a telescopic frame. The level is installed in the middle of the top of the mounting base. A number of support frames are evenly installed at the bottom edge of the mounting base through a rotating shaft. A telescopic frame is installed in the middle of the inside of the support frame. A pedal is installed on the side surface of the bottom end of the telescopic frame. A pointed tip is connected to the bottom of the bottom end of the telescopic frame. A connecting block is connected to the bottom end of the support frame. A top screw is installed on the surface of the connecting block. A protective block is connected to the bottom of the support frame below the connecting block. A support block is provided at the bottom edge of the protective block.

[0006] Preferably, a slider is fixedly installed at the top end of the telescopic frame. Both sides of the slider are in interference fit and sliding connection with the inner cavity wall of the support frame. Scale lines are provided on the surface of the support frame.

[0007] Preferably, the surfaces of the protective block and the support block are wrapped with protective sleeves.

[0008] Preferably, anti-slip patterns are provided on the top surface of the pedal.

[0009] Preferably, a storage groove is provided on the surface of the protective block. The telescopic frame is in interference fit and sliding connection with the storage groove. The telescopic frame penetrates through the corresponding connecting block.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the arrangement of the protection block, the protection block can protect the pointed head. When the telescopic frame is retracted, the pointed head can be stored inside the storage groove, and the protection block protects the pointed head to prevent the pointed head from stabbing the human body, vehicle body or other objects, thus facilitating the user to carry the land surveying level; By providing anti-slip patterns on the top of the pedal, it is convenient for the staff to install and fix the telescopic frame and avoid slipping during installation; By providing scale lines on the surface of the support frame, the height of the telescopic frame can be accurately adjusted according to actual usage requirements.
