Abstract
The utility model relates to an internal-external rectangle detection ruler, including a main ruler and an auxiliary ruler mutually hinged. The main ruler is provided with an indication meter and a gradienter; the gradienter consists of a base and a spirit bubble; the spirit bubble is fixed inside the base and the base is located in the main ruler through a bolt; a panel is embedded in the circumference of the base and the panel is fixed on the main ruler. The utility model overcomes the defect that the traditional internal-external rectangle detection ruler is often in an inclined position after assembling and calibrating the spirit bubble, which affects the level detection accuracy and the overall performance, thus effectively improving the reliability of the internal-external rectangle detection ruler in level detection. The utility model has the advantages of simple structure, convenient carry and use and high detection accuracy.
Description
The utility model relates to a kind of inside and outside right angle detection ruler.
Inside and outside right angle detection ruler is the special detection tool that is used to detect negative and positive right angle deviation in the construction work, is made of main scale that is hinged and secondary chi usually, and main scale is provided with indicating value gauge outfit and level meter.This traditional inside and outside right angle detection ruler, spirit bubble in its level meter directly is fixed on the main scale by pedestal by screw, because the error that spirit bubble and pedestal exist in the mill, behind assembling calibrated horizontal bubble, sometimes pedestal also is in crooked position, not only influence the precision of horizontal detection, also reduced the overall performance of inside and outside right angle detection ruler simultaneously.
The purpose of this utility model is to solve existing inside and outside right angle detection ruler behind assembling calibrated horizontal bubble, and pedestal often is in crooked position, influences the problem of horizontal detection precision and overall performance.The utility model comprises main scale and the secondary chi that is hinged, and main scale is provided with indicating value gauge outfit and level meter, and level meter is made of pedestal and spirit bubble, and spirit bubble is fixed in the pedestal, and pedestal is positioned in the main scale by screw.
Spirit bubble is installed in the pedestal of two symmetries.
The outer nested panel of the circumference of pedestal, panel is fixed on the main scale.
The utility model has effectively improved the reliability of inside and outside right angle detection ruler when horizontal detection by above-mentioned specific design, have simple in structure, portably use conveniently, advantage that accuracy of detection is high.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cut-open view of Fig. 1.
As shown in the figure, the utility model comprises main scale 1 and the secondary chi 2 that is hinged, and its articulated structure is formed by bearing pin 8 riveted joint backs.Main scale 1 is provided with indicating value gauge outfit 3 and level meter, and level meter is made of pedestal 4 and spirit bubble 5, and spirit bubble 5 is fixed in the pedestal 4, and its fixed form can be that spirit bubble 5 is installed in the pedestal 4 of two symmetries.Pedestal 4 is positioned in the main scale 1 by screw 6, the outer nested panel 7 of the circumference of pedestal 4, and panel 7 can be adhesively fixed on the main scale 1 by glue.
