[0018] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the following will be to the technical scheme in the utility model embodiment, clear, complete, with the drawing in the utility model embodiment, obviously, the described embodiment is the part of the embodiment of the utility model, instead of all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by ordinary skilled person in the art without making creative labor belong to the scope of the utility model protection.

[0019] As Figs. 1-3The utility model discloses a kind of base pile diameter convenient scale, including positioning rod 1 and ruler 2, positioning rod 1 is provided with hook terminal 3 in left and right ends, positioning rod 1 is provided with recess 4 in the central bottom, recess 4 is rotatably connected with butt joint column 6 in through rotating shaft 5, and butt joint column 6 is provided with through hole in it;

[0020] Ruler 2 is set through the through hole, and the front end of ruler 2 is provided with a ruler hook 7; ruler 2 is perpendicular to the positioning rod 1; the inner side of hook terminal 3 is provided with an anti-slip rubber strip 8.

[0021] The lower end of hook terminal 3 is provided with a positioning hook 9. The upper end of butt joint column 6 is provided with a universal level bubble device 10. Ruler 2 is a tape measure, and the tail end of ruler 2 is provided with a tape case 11 for winding and storing the ruler.

[0022] Working principle:

[0023] When measuring the diameter of the pile, the two ends of the positioning rod are located on the circumference of the pile, and the hook terminals at the two ends of the positioning rod are connected stably with the base pile. According to the actual situation, the anti-slip rubber strip is clamped or the positioning hook is connected.

[0024] The ruler is connected with the positioning rod by passing through the butt joint column in the center of the positioning rod (the positioning rod is perpendicular to the ruler). According to the theorem that the perpendicular line of any chord in a circle passes through the center of the circle, when measuring the diameter of the pile, the positioning rod is a chord in the circle on the upper surface of the base pile. At this time, the ruler perpendicular to the positioning rod is the perpendicular line of the positioning rod, that is, at this time, the ruler can pass through the center of the pile, that is, by introducing the positioning rod, the diameter position can be quickly positioned. Then, the ruler is adjusted up and down, and the universal level bubble device is used to ensure that the ruler is horizontal, so that the diameter of the pile can be quickly measured by one person, time is saved, and efficiency is improved.

[0025] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
