Description

Technical Field

[0001] The utility model relates to the field of connecting rotating shafts, in particular to a wire-passing rotating shaft. Background Art

[0002] In the design of some electronic products, the control box body and the main body are connected through a coaxial line with connectors at both ends, and the connectors at both ends are plugged into the control box body and the main body respectively to realize the communication between the control box body and the main body. At present, the conventional coaxial line has been installed with the corresponding connectors at both ends when the product leaves the factory, and the whole is a standard part, and its connector cannot be disassembled, and the conventional connector is large in size. However, the main body and the control box body of some electronic products can rotate relative to each other, which causes the coaxial line to be easily worn due to the relative rotation of the two. In order to prevent the wear of the wire, a wire passing shaft is usually set on the wire, but the existing wire passing shaft is a cylindrical shaft body set in one piece, such as: the Chinese patent with announcement number CN218954559U and application date November 21, 2022, discloses a display wire passing shaft, whose shaft body is a cylindrical structure set in one piece. When in use, the wire is passed through the wire hole on the shaft body, but because the diameter of the wire hole is small, it cannot be sleeved on the coaxial line with connectors at both ends, so the coaxial line cannot be protected from wear. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a wire passing rotating shaft which can be sleeved on a coaxial line with connectors at both ends to protect the coaxial line from wear.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A thread-passing rotating shaft comprises an internally hollow shaft body, wherein the shaft body comprises a shaft shell 1 and a shaft shell 2 which are arranged opposite to each other, wherein the outer surface of the shaft body is provided with two annular grooves which are spaced apart along the axial direction, and wherein fasteners are provided on the annular grooves, and the shaft shell 1 and the shaft shell 2 are detachably fixed by the fasteners.

[0006] Preferably, a non-planar mating surface one is provided on the side of shaft shell one facing shaft shell two, and a non-planar mating surface two is provided on the side of shaft shell two facing shaft shell one. When shaft shell one and shaft shell two are relatively buckled, mating surface one cooperates with mating surface two.

[0007] Preferably, the first mating surface and the second mating surface are both stepped surfaces, serrated surfaces or corrugated surfaces.

[0008] Preferably, the fastener is a retaining spring.

[0009] Compared with the prior art, the advantage of the utility model is that the shaft body includes detachable shaft shell one and shaft shell two. When the connectors at both ends of the coaxial line are large and cannot be detached, the detachable shaft shell one and shaft shell two are mounted on the coaxial line by snapping together; two annular grooves distributed at intervals are provided on the shaft body, and fasteners are provided on the annular grooves. The shaft shell one and shaft shell two are detachably fixed by the fasteners, which is convenient to use; the shaft body passes through the control box body and the rotating shaft mounting holes at the lower end of the main body, and two retaining springs are respectively pressed against the two sides of the control box body and the main body, so that the shaft body is axially fixed to the control box body and the lower end of the main body; the coaxial line passes through the shaft body, so that the shaft body has the effect of protecting the coaxial line from wear; the non-planar mating surface one provided on the shaft shell one is relatively snapped with the non-planar mating surface two provided on the shaft shell two, which can prevent radial movement when the shaft shell one and the shaft shell two are snapped together.
