Detailed ways

The technical solutions of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in Figures 1-3, a signal switching device for communication engineering proposed by the present utility model includes a signal adapter body 1 and a data line 2 inserted into the wiring hole of the signal adapter body 1. Data The outer side of the wire 2 is sleeved with a protective tube 3, the outer side of the protective tube 3 is fixed with an external ring block 6, the inner wall of the protective tube 3 is provided with a receiving annular groove, and two symmetrical plate annular blocks 7 are slidably arranged in the receiving annular groove, The inner circumferential surface of the plate ring block 7 is bonded and fixed with a sealing gasket 8, the outer side of the receiving ring groove is communicated with a receiving inner hole, and a tension spring 10 is fixed between the inner wall of the receiving inner hole and the outer side of the plate ring block 7. Under the influence of other external forces, the elastic force of the tension spring 10 can pull the plate ring block 7 into the receiving ring groove, the outer circumference of the external ring block 6 is provided with an oblique arc groove 14, and the outer side of the plate ring block 7 is fixed with a connection. block 9, and the outer side of the connecting block 9 penetrates the outer ring block 6 and extends into the inclined arc groove 14, the outer side of the connecting block 9 is provided with a slope a, and the push block 13 is provided with a slope b matching the slope a. A push block 13 fixed to the main body 1 of the signal adapter through the connecting rod 12 is arranged in the arc-shaped groove 14, so that the push block 13 enters the inclined arc-shaped groove 14, and when the external ring block 6 is rotated, the push block 13 The mutual cooperation between the inclined surface b of the connecting block 9 and the inclined surface a of the connecting block 9 can make the connecting block 9 squeeze the plate ring block 7 inward, and the protection tube 3 is fixed with a twisting ring 11, and the protection tube 3 can be twisted by twisting the ring 11. 6 with the outer ring block.
