Description

Hexagonal stud structure Technical Field The utility model relates to the technical field of hexagonal stud equipment, in particular to a hexagonal stud structure. Background The hexagonal stud is a common mechanical fastener, and is widely applied to the fields of electronic equipment, mechanical equipment, constructional engineering and the like because the head of the hexagonal stud is hexagonal, and the hexagonal head is convenient to mount and dismount by using a spanner or a sleeve and can bear larger torque. The hexagonal combined stud comprises a nut and a screw rod, wherein the nut and the screw rod directly form an integrated structure, fastening side edges are formed on the outer side of the nut, the fastening side edges are respectively arranged on the six side surfaces of the nut, attaching pieces are further arranged on the fastening side edges and are in elliptical plane shapes, cross threads are further arranged on the outer side of the nut, threads are arranged on the outer surface of the screw rod, a deformed silica gel gasket is further arranged on the inner side of the threads, the top of the screw rod is in overlapping connection with the center of the nut, an arc wedge is formed at the bottom of the screw rod, a combined gasket is sleeved between the nut and the screw rod, the combined gasket comprises a break-point gasket and a full-closed gasket, embedded gaskets are respectively arranged between the break-point gasket and the full-closed gasket and on the outer side of the full-closed gasket, the fastening effect is improved, the applicability of the screw rod is improved, the requirements of different conditions can be met by increasing the number and types of the gaskets, and the convenience of use is improved. Although the hexagonal stud can carry out combination operation on the breakpoint washers, after the hexagonal stud is used for a long time, rust is easy to occur at the hexagonal screw plate, and after the installation is completed, the hexagonal screw plate is inconvenient to replace if the hexagonal screw plate is more rusted, so that the whole bolt is detached, the practicability of the hexagonal bolt is reduced, and therefore, a hexagonal stud structure is urgently needed to solve the problems. Disclosure of utility model The present utility model is directed to a hexagonal stud structure, so as to solve the problems set forth in the above-mentioned background art.
