Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nuts, and more specifically, particularly relates to a backstop and anti-loosening nut. Background Art
[0002] A nut is a screw cap that is screwed together with a bolt or screw rod to play a fastening role. It is an element that must be used in all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, and non-ferrous metals (such as copper). A nut is a screw cap that is screwed together with a bolt or screw rod to play a fastening role. It is an element that must be used in all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, and non-ferrous metals (such as copper). A nut is a part that tightly connects mechanical equipment. Through the internal thread, nuts and bolts of the same specification can be connected together.
[0003] Based on the above, the inventor found the following problems: Under the influence of the vibration of mechanical equipment during long-term use, the nut is very easy to loosen, resulting in an insufficiently tight connection between the bolt and the nut, thereby affecting the operation of the machine and indirectly bringing inconvenience to the staff.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a backstop and anti-loosening nut is provided with the expectation of achieving a more practical value. Content of the Utility Model
[0005] The purpose and effect of a backstop and anti-loosening nut of the utility model are achieved by the following specific technical means:
[0006] A backstop and anti-loosening nut includes a bolt and a nut. A first thread is provided on the surface of the bolt. The nut is installed on the bolt. A set of fixing parts is fixedly installed at the bottom end of the nut. A limiting mechanism is installed on the fixing parts. The limiting mechanism includes a handle. An arc-shaped limiting plate is movably installed at one end of the handle. A rubber pad is installed on one side of the arc-shaped limiting plate. A threaded hole is formed on the surface of the fixing parts. A third thread is provided on the surface of the handle. The handle is installed on the threaded hole, and the third thread engages with the threaded hole. The rubber pad is fitted and installed on the surface of the bolt.
[0007] Further, a second thread is provided inside the nut, and the first thread engages with the second thread.
[0008] Further, the surfaces of the bolt and the nut are both plated with an anti-rust agent.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] Through the cooperation among the handle, the arc-shaped limiting plate and the rubber pad, the staff can first install the nut onto the bolt, and then fit the rubber pad onto the surface of the bolt through the handle, thereby limiting the nut and preventing the vibration of the mechanical equipment from loosening the nut. The operation steps are very simple, indirectly improving the stability efficiency, and this design greatly increases the practicability.
[0011] Through the design of the rust inhibitor, it can effectively prevent the nut from rusting during use, indirectly extending the service life, and also facilitating the subsequent maintenance or repair by the staff, which is very simple. Description of the Drawings
