Description

Detachable nut Technical Field The application relates to the technical field of mechanical connection, in particular to a detachable nut. Background In the field of mechanical connection, nuts are widely used as an important fastening part in various mechanical equipment, building structures, industrial production and other scenes. Along with the continuous development of industrial technology, the use demands for nuts are increasingly diversified and complicated, the quality and the performance of the nuts are directly related to the stability and the reliability of the whole connecting structure, and the nuts play a vital role in ensuring the normal operation of mechanical equipment and the stability of the structure. Conventional nuts are typically of one-piece construction and require the bolt to be threaded completely through the components to be joined during installation. In some cases where space is limited, such as in a narrow gap or in a closed cavity, the installation work becomes difficult or even impossible due to the inability to fully nest the bolts. In addition, when the equipment needs to be maintained or parts are replaced, other surrounding parts are often required to be detached firstly by detaching the integrated nut, so that the maintenance difficulty and the workload are increased, and other parts can be damaged due to improper operation. The existing integrated nut has obvious defects when dealing with the working conditions that the space is limited or frequent disassembly is needed, the local assembly and disassembly cannot be realized, the assembly and disassembly operation can be completed only on the premise that the bolt can integrally pass, and the use flexibility of the integrated nut under the special working condition is severely limited. Disclosure of utility model In order to solve the problem of nuts in the background art, the application provides a detachable nut. The application provides a detachable nut, which adopts the following technical scheme: The utility model provides a removable nut, includes the nut components of a whole that can function independently that sets up in pairs, arbitrary the both ends of nut components of a whole that can function independently all are provided with spread groove and connecting block respectively, arbitrary the connecting block of nut components of a whole that can function independently all forms sliding fit with the spread groove that sets up the nut components of a whole that can function independently relatively, the length direction of spread groove and the slip direction of connecting block all are parallel with the axis of rotation of nut. Through adopting above-mentioned technical scheme, can realize the dismantlement installation and the dismantlement of nut, solved the problem that traditional integral type nut is difficult to the installation and dismantlement under the limited scene in space, improved the flexibility that the nut used under special operating mode, avoided the trouble of demolishing other parts around when maintaining, reduced the maintenance degree of difficulty and work load, reduced the risk of damaging other spare parts. Preferably, the connecting groove is a dovetail groove, and the connecting block is a dovetail bump matched with the dovetail groove. Through adopting above-mentioned technical scheme, the spread groove adopts the dovetail, the connecting block adopts the dovetail lug that matches with it, has further strengthened the stability of being connected between the components of a whole that can function independently of two nuts, prevents that both from unexpected separation in the use. Preferably, the middle parts of the connecting grooves and the connecting blocks are provided with fixing holes, and fixing rods are arranged in the fixing holes in a penetrating mode. Through adopting above-mentioned technical scheme, set up the fixed orifices and wear to establish the dead lever at the middle part of spread groove and connecting block, can prevent that the connecting block from sliding in the spread groove, make the nut components of a whole that can function independently that sets up to connect more stable. Preferably, the inner side surface of the nut split body is provided with internal threads, and the internal threads of the two thread split bodies are continuously arranged to form a complete thread through hole. By adopting the technical scheme, the detachable nut comprises nut split bodies which are arranged in pairs and are in sliding fit with the connecting grooves and the connecting blocks, the nut split structure enables the nut to be detachable and to be locally installed and detached at the limited space, internal threads are arranged on the inner side surface of the nut split bodies and are continuously arranged to form complete threaded through holes, the detachable nut can be matched with bolts like a traditional nut, the fastening function is realized, and the use fl
