Abstract
The utility model relates to a line pipe groove angle measuring device, which comprises a connection rod. The line pipe groove angle measuring device is characterized in that the end part of the connection rod is provided with a rotary ruler; the end part of the connection rod is provided with a screw hole; the middle of the rotary ruler is provided with an inner screw hole; the rotary ruler is in rotation connection with the screw hole of the connection rod via the inner screw hole and a bolt; the inner side of the lower end of the rotary ruler is recessed to form a sunken area; the surface of the sunken area is the measuring surface; the measuring surface is parallel to the inner surface of the upper end of the rotary ruler; the extending surface of the measuring surface passes through the circle of the inner screw hole; two angle range scale lines are arranged on the connection rod; and extending lines of the two angle range scale lines respectively pass through the circle of the screw hole. According to the line pipe groove angle measuring device, whether the line pipe groove angle is qualified can be quickly judged, the operation is simple, the use is convenient, and the device is simple and easy to understand.
Description
Technical field
The utility model relates to a kind of angle measurement unit, especially a kind of line pipe groove angle measurement mechanism.
Background technology
The pipe end slope-mouth angle of line pipe is according to API 5L standard, general angle is 30～35 degree, and factory goes to measure with Special angle ruler, but Special angle ruler reading dial plate is smaller, during measurement, need eyes pasting dial reading, it is not very convenient using.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of line pipe groove angle measurement mechanism, and this measurement mechanism is easy to operate.
According to the technical solution of the utility model: described line pipe groove angle measurement mechanism, comprise connecting rod and rotation chi, it is characterized in that: the end of described connecting rod is provided with screw, the middle part of rotation chi is provided with inner bolt hole, and rotation chi is rotationally connected by the screw of inner bolt hole and bolt and connecting rod; The concave-shaped district that is in depression inside the lower end of described rotation chi, the surface of depressed area is measurement face; Described measurement face is parallel with the inside surface of rotation chi upper end, measures the extended surface of face through the inner bolt hole center of circle; On described connecting rod, be provided with twice angular range scale mark, the extended line of twice angular range scale mark is respectively by the center of circle of screw.
The angle of described twice angular range scale mark and vertical plane is respectively 30 degree and 35 degree.
Technique effect of the present utility model is: whether this measurement mechanism energy Quick Measurement line pipe groove angle is qualified, easy to use.
