Screw with right-hand and left-hand threads

Abstract

For a screw at a certain part of a vehicle or a machine, the situation of thread dropping of a nut of a big screw occurs due to vibration during working to cause the fact the work cannot be completed successfully, and even personal and property safety risks occur sometimes. In order to overcome the defects in the prior art, the invention provides a screw with right-hand and left-hand threads, which is safe in use. The structure of the screw is shown in pictures 1, 2 and 3. The screw with the right-hand and left-hand threads comprises a left-hand thread nut and a right-hand thread nut; during the use, the left-hand thread nut B anticlockwise runs onto the left threads A1 of the screw A with the right-hand and left-hand threads, and the right-hand thread nut C clockwise runs onto the right-hand threads A2 of the screw A with the right-hand and left-hand threads. By using the screw provided by the invention for fixing an object, even if the object vibrates greatly, the situation of thread dropping of the nuts does not occur easily, strong guarantee is provided for people's work and safety production, and the screw has an excellent market application prospect.

Description

technical field [0001] The invention relates to a positive and negative screw, which is suitable for the screw on a vibrating large machine. Background technique [0002] For the screws in a certain part of the vehicle or machine, the nuts sometimes come off due to the vibration of the large screws during work. That is to say, the work cannot be completed smoothly, and sometimes even personal and property safety hazards occur. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a safe anti-thread screw. [0004] The present invention is achieved through the following technical solutions: [0005] The present invention comprises an anti-screw screw, an anti-screw nut, and a normal-screw nut, wherein: the anti-screw screw is marked as A, and A1 represents the anti-screw part of the anti-screw screw, which is used for the anti-screw nut to run counterclockwise to Above, A2 represents the normal thread part of the anti-thre...
