In the figure: 1. a base; 11. a housing; 12. a circuit board; 13. a threaded knob; 14. a positioning block; 15. a positioning seat; 16. a built-in hole; 17. a plate frame; 18. a dust screen; 2. a groove; 21. a spring; 22. a bayonet lock; 23. a through hole; 3. a card slot; 31. an elastic card.

Detailed Description

Please refer to fig. 1 and 2, the radio convenient to maintain comprises a base 1, a casing 11 covers the base 1, a circuit board 12 is arranged on the base 1, the circuit board 12 is fixed with the base 1 through a threaded knob 13, a positioning block 14 is fixed on the base 1, a positioning seat 15 is fixed on the casing 11, the positioning block 14 and the positioning seat 15 are provided with a built-in hole 16 on the casing 11, heat dissipation and ventilation can be performed, a plate frame 17 covers the casing 11, and a dust screen 18 covering the built-in hole 16 is fixedly embedded on the plate frame 17, so that a dust blocking effect can be achieved.

Referring to fig. 2, a threaded hole is formed in the surface of the circuit board 12, a thread groove is formed in the base 1, and the threaded knob 13 is in threaded arrangement with the threaded hole and the thread groove, so that the circuit board 12 can be conveniently detached, and the circuit board 12 can be conveniently maintained integrally.

Referring to fig. 2, the number of the aligning blocks 14 and the aligning seats 15 is two, and the aligning blocks and the aligning seats are symmetrically distributed, so that the shell 11 and the base 1 can be quickly butted.

Referring to fig. 2, a groove 2 is formed in the aligning block 14, a bayonet 22 is slidably arranged in the groove 2, and the bayonet 22 is connected with the groove 2 through a spring 21, so that the telescopic resetting stability of the bayonet 22 is facilitated.

Referring to fig. 2, the alignment seat 15 is provided with a through hole 23, and the pin 22 and the through hole 23 are slidably inserted into the through hole 23, so as to facilitate the detachment of the housing 11 from the base 1 and the maintenance of the components on the circuit board 12.

Referring to fig. 2, the housing 11 is provided with a slot 3, the plate frame 17 is fixed with an elastic clip 31, and the elastic clip 31 is fastened to the slot 3, so that the dust screen 18 can be periodically detached to clean the attached dust.
