One end of the antenna mast concave connector is inserted into one end of the antenna mast main tube, and one end of the antenna mast convex connector is inserted into the opposite end of the antenna mast main tube. The inner cavity of the antenna mast concave connector has a first through groove and a second through groove. The second through groove is located above the first through groove and is opposite to and communicates with the first through groove. The first through groove and the second through groove form a receiving cavity adapted to the antenna mast convex connector.

[0028] The composite copper sleeve is disposed in the second through groove, the antenna mast spring piece assembly is sleeved on the outer wall of the antenna mast concave joint away from the antenna mast main tube, and the antenna mast locking knob assembly is respectively sleeved on the outer wall of the antenna mast concave joint and the antenna mast spring piece assembly, and the antenna mast locking knob assembly is threadedly connected to the antenna mast concave joint.

[0029] As can be seen from the above description, the beneficial effects of the present invention are as follows:

[0030] By incorporating an antenna mast locking knob assembly, an antenna mast spring assembly, an antenna mast concave joint, an antenna mast convex joint, and a composite copper sleeve, this design achieves advantages such as rapid locking and disassembly, lightweight portability, good stability, and quick erection, while significantly reducing labor intensity. The antenna mast concave joint has a first and second through slot within its inner cavity, with the composite copper sleeve positioned within the second through slot. The antenna mast spring assembly is fitted onto the outer wall of the concave joint at the end furthest from the main antenna mast tube, enabling rapid alignment and automatic lubrication, further improving the efficiency of antenna assembly and disassembly. This novel medium-wave navigation antenna design is widely used in medium-wave navigation communication, meeting requirements for rapid assembly and disassembly, portability, and temporary outdoor installation, improving antenna communication reliability, and adapting to various harsh environments.

[0031] Furthermore, the antenna mast recessed connector includes a first connector and a second connector. The first connector and the second connector are integrally formed. The first connector is inserted into the inner cavity of the antenna mast main tube. The second connector is located in the inner cavity of the antenna mast locking knob assembly and is threadedly connected to the antenna mast locking knob assembly. The first through groove is disposed in the inner cavity of the first connector and the second through groove is disposed in the inner cavity of the second connector.

[0032] Furthermore, the diameter of the second through groove is larger than the diameter of the first through groove.

[0033] Furthermore, the inner cavity of the antenna mast locking knob assembly is also provided with an elastic retaining ring, which is located above the antenna mast spring piece assembly.

[0034] As can be seen from the above description, by setting an elastic retaining ring in the inner cavity of the antenna mast locking knob assembly, the antenna mast locking knob assembly can be prevented from disengaging from the antenna mast body, thus playing a limiting and buffering role.

[0035] Furthermore, the antenna mast spring assembly is mounted on the outer wall of the antenna mast recessed joint using countersunk screws.

[0036] As can be seen from the above description, by setting the above structure, the antenna mast spring assembly can be more firmly fitted onto the outer wall of the antenna mast recessed connector, thereby further improving the efficiency of assembly and disassembly.

[0037] Furthermore, the antenna mast spring assembly includes a first sleeve and a second sleeve, the first sleeve and the second sleeve are integrally formed, the vertical cross-sectional shape of the first sleeve is rectangular, the vertical cross-sectional shape of the second sleeve is an isosceles trapezoid, the second sleeve is located above the first sleeve, the second sleeve and the first sleeve are opposite to each other and communicate with each other, and the first sleeve is sleeved on the outer wall of the antenna mast recess joint.

[0038] Furthermore, the outer wall of the second sleeve has two or more strip-shaped through grooves along the height direction, and the two or more strip-shaped through grooves are equally spaced on the outer wall of the second sleeve.

[0039] As can be seen from the above description, by setting the above structure, the fit between the antenna mast spring assembly and the antenna mast locking knob assembly can be further improved, thereby further improving the efficiency of disassembly and assembly.

[0040] Furthermore, the composite copper sleeve is a self-lubricating graphite composite copper sleeve.

[0041] As can be seen from the above description, the use of self-lubricating graphite composite copper bushings can ensure fitting accuracy and further improve the efficiency of disassembly and assembly.
