Mechanism based on multi-type positioning shell

Abstract

The invention discloses a mechanism based on a multi-type positioning shell. The mechanism comprises an installation frame mainly formed by two installation columns and two protection frames. Two connecting plates are arranged on and connected with the installation columns. The center lines of the connecting plates are vertical to the center lines of the installation columns. Each connecting plate is equipped with a fixing plate correspondingly; a connecting bar one and a connecting bar two are arranged between each connecting plate and the fixing plate and are both connected with the corresponding fixing plate and connecting plate; a long hole three and a long hole four are arranged in a side wall of each fixing plate; an expansion bolt one is arranged in the long hole three; and an expansion bolt two is arranged in the long hole four. The mechanism is simple in structure, allows shell replacement and maintenance without removing a support, does not cause interference, is firm in fixing, can be used for long term, reduces the maintenance cost, and ensures the strength of a wall.

Description

technical field [0001] The invention relates to a fixing mechanism, in particular to a mechanism based on multi-type positioning housings. Background technique [0002] Positioning means to determine the position and point out the direction. The Global Positioning System (Global Positioning System) is a technology that combines satellite and communication development, and uses navigation satellites for time measurement and distance measurement. The Global Satellite Positioning System (GPS for short) was developed by the United States in the 1970s. It took more than 20 years and cost 20 billion U.S. dollars. It was fully completed in 1994. A new generation of satellite navigation and positioning system with all-round real-time three-dimensional navigation and positioning capabilities in land, sea and air. After nearly ten years of use by my country's surveying and mapping departments, the global satellite positioning system has been successfully used in geodetic surveying, ...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the complex installation structure of the casing of the above-mentioned existing multi-type positioning system, and they are all directly fixed on the wall or other structures. When the casing needs to be replaced, the entire frame must be removed, the process is complicated, and When reinstalling, the damage to the wall is great, the fixing effect is poor, and the service life is affected. A mechanism based on multi-type positioning shells is designed. The structure of the mechanism is simple, and the shell can be fixed without removing the bracket. Replacement and maintenance will not cause interference, the fixation is firm, and it can be used for a long time, which reduces maintenance costs, ensures the strength of the wall, and solves the complex installation structure of the existing multi-positioning system, which is directly fixed on the On the wall or other structures, when the shell needs to be replaced, the entire frame needs to be removed, which is a complicated process, and the wall will be greatly damaged when reinstalled, the fixing effect is poor, and the service life is affected
