Abstract

The invention discloses a box staff capable of being straightened quickly and accurately, threaded holes are formed in the two sides of the top of a box staff body, limiting screws are in threaded connection with the interiors of the threaded holes, an extension ruler is arranged in the box staff body in a sleeved mode, limiting grooves are formed in the two sides of the extension ruler, and the limiting grooves and the limiting screws are used in cooperation. An electronic horizontal bubble instrument is arranged on the lower portion of the box staff body, a threaded portion is in threaded connection with a balance weight ball, and a base is arranged on the lower side of the balance weight ball. The base is placed on the ground of a to-be-detected place, the balance weight ball is placed in a spherical groove of the base, the balance weight ball can enable the box staff body to be in a vertical state through the tumbler principle, the balance weight ball can roll and reset in the spherical groove conveniently through steel balls in the ball grooves, and meanwhile checking and correcting are conducted through an electronic level bubble instrument. And the purpose of quickly straightening the box staff body is achieved.

Description

technical field [0001] The invention relates to the technical field of engineering measuring tools, and specifically relates to a tower ruler that can be quickly and accurately adjusted. Background technique [0002] The tower ruler is a kind of leveling ruler. Most of the early leveling rods are made of wood, heavy and limited in length (generally 2m), and it is inconvenient to carry when measuring. Later, it is gradually made of aluminum alloy and other light-weight and high-strength materials. It adopts a tower-type shrinking form, which is convenient to pull out when in use, and the single-elevation measurement range is greatly improved. The length is generally 5m. Tower-shaped, so it is often called a tower ruler. The tower ruler is an essential tool for engineering surveying and topographical surveying. It is used to measure the topography of certain places, so as to provide reliable data for construction. The existing tower ruler is inconvenient to straighten the t...
