Problems solved by technology
[0002] Usually to judge the left and right rotation of the external thread, you must have a certain production practice experience, that is, frequent contact and frequent use, and the accurate judgment can only be made after the accumulation reaches a certain level; because it is only after having certain experience that the accurate judgment can be achieved. Judgment is not suitable for beginners, and sometimes there are judgment errors, which affect the normal operation of production and construction. For this reason, a left-handed and right-handed thread judgment method is needed

Embodiment Construction
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0015] refer to Figure 1-2 , a method for judging left-handed and right-handed threads, comprising the following steps:
[0016] Step 1: Point the long end of the L-shaped indicator to the axial direction of screw 1;
[0017] Step 2: Point the short end of the L-shaped indicator to the inclined direction of the thread 11 on the screw 1;
[0018] Step 3: Determine whether the short end of the L-shaped indicator is on the left or right of the long end. If it is on the left, it means that the thread on screw 1 is left-handed. If it is on the right, it means that the thread on screw 1 is right-handed. Screw thread.
[0019] In this embodiment, the L-shaped indicator ...

The invention discloses a left-handed thread and right-handed thread judging method, relates to the field of thread recognition, and the method comprises the following steps: 1, enabling the long endof an L-shaped indicating piece to point to the axial direction of a screw rod; 2, enabling the short end of the L-shaped indicating piece to point to the inclination direction of a thread on the screw rod, 3, judging whether the short end of the L-shaped indicating piece is located on the left side or the right side of the long end, if left, it is indicated that the thread on the screw rod is a left-handed thread, and if right, it is indicated that the thread on the screw rod is a right-handed thread. According to the scheme, the left-handed rotation and the right-handed rotation of the external thread can be directly judged through the directions of the thumb of the left hand and the thumb of the right hand of a normal person, and convenience, rapidness, simplicity, practicability and accuracy are achieved; the judging method is simple and easy to learn, and is very suitable for beginners and related cross-industry persons; the judging method is simple and easy to learn, and can accurately judge the left-handed rotation and the right-handed rotation of the external thread, so that the judging method has very high use value in daily production.
Description
technical field [0001] The invention relates to the field of thread identification, in particular to a method for judging left-handed and right-handed threads. Background technique [0002] Usually to judge the left and right rotation of the external thread, you must have a certain production practice experience, that is, frequent contact and frequent use, and the accurate judgment can only be made after the accumulation reaches a certain level; because it is only after having certain experience that the accurate judgment can be achieved. Judgment is not suitable for beginners, and sometimes there are judgment errors, which affect the normal operation of production and construction. For this reason, a left-handed and right-handed thread judgment method is needed. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a left-handed and right-handed screw thread judgment method. [0004] In order to...
