Description

Screw-connection fixed adapter Technical Field The utility model relates to the technical field of adapters, and particularly discloses a screw-connection fixed adapter. Background In the field of modern electronic devices, an adapter is used as a key component for realizing signal transmission and device connection between different interfaces, and the structural stability and the functional reliability of the adapter are important. The traditional adapter adopts plug-in connection or single thread fixation more, has the problems of loose connection, poor tightness and the like, is easily affected by external force impact and environmental factors to cause unstable signal transmission and even causes equipment damage. Although the partial adapter has a sealing structure, the matching mode of the sealing component, the shell and the internal assembly is complex, the production cost is high, and the assembly efficiency is low. Disclosure of utility model In order to overcome the defects and shortcomings in the prior art, the utility model aims to provide a screw-connection fixed type adapter. The screw-connection fixed type adapter comprises a shell, an adapter component arranged in the shell and a locking component arranged on the shell, wherein two ends of the adapter component are respectively a first electric connector and a second electric connector which are in plug connection with an external butt joint electric connector, external threads are arranged on the shell, the locking component comprises a first boss protruding from the outer side of the shell, a nut matched with the first boss and sleeved on the outer side of the external threads in a screw-connection mode, the nut axially moves along the external threads of the shell, the nut rotates towards one end close to the first boss, and the nut and the first boss clamp the external component together to achieve fixed connection between the shell and the external component. The screw-connection fixed adapter realizes stable connection with an external component through the matching structure of the external thread of the shell and the first boss and the nut, has the beneficial effects that the screw-connection fixed adapter is higher in vibration resistance and stability compared with the traditional plug-in connection, can effectively prevent loosening and falling, is convenient for quick disassembly and reuse in a nut rotating and clamping mode, is formed by turning the external thread by adopting a metal material, is formed by the first boss and the shell integrally, is accurately matched with the external thread of the shell, can adjust the clamping force on the external component by controlling the rotation number of the nut, ensures firm connection, avoids the damage of the component due to overtightening, and is suitable for interface switching scenes of various devices. The locking assembly further comprises an annular buffer ring sleeved outside the external thread, and the annular buffer ring (7) is located between the first boss and the nut.
