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

One is silk screw anyway
Technical field
The present invention relates to a kind of positive and negative screw, be applicable to shake the screw on large machine.
Background technique
At the screw at vehicle or certain position of machine, because during work, vibrations king bolt nail has the situation of nut running sometimes.Namely cause work not complete smoothly, sometimes even produce personal safety as well as the property safety dangerous.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of screw of silk anyway of use safety.
The present invention is achieved by the following technical solutions:
The invention of this reality comprises silk screw anyway, anti-silk nut, positive silk nut is formed, wherein: the described screw of silk is anyway labeled as A, A1 represents the anti-silk part of silk screw anyway, above running to counterclockwise for anti-silk nut, A2 represents the positive silk part of silk screw anyway, above running to clockwise for positive silk nut.Described anti-silk nut is labeled as B, for running to the anti-silk part of screw anyway counterclockwise.Described positive silk nut is labeled as C, for running to the positive silk part of silk screw anyway clockwise.
Accompanying drawing explanation
Fig. 1 is the present invention's silk screw schematic diagram anyway
Fig. 2 is the present invention's anti-silk nut schematic diagram
Fig. 3 is the present invention's positive silk nut schematic diagram
Embodiment
Structure as shown in Figure 1, Figure 2, Figure 3 shows, the present invention includes silk screw anyway, anti-silk nut, positive silk nut is formed, above anti-silk A1 during use, anti-silk nut B being run to counterclockwise silk screw A anyway, above the positive silk A2 positive silk nut C being run to clockwise silk screw A anyway.
Use fixed object of the present invention, even if object vibrations are large also not easily produce nut running situation, produce for people's work safety and provide sound assurance, this invention has good market application foreground.
