The invention will be further described with reference to the accompanying drawings and preferred embodiments.

Example 1

Referring to fig. 1 to 3, the large-diameter plastic-coated metal hose for electric wires and cables according to the present embodiment includes a metal hose body 10, self-fixing joints 20 disposed at two ends of the metal hose body 10, and a fall preventing assembly 30 for winding the metal hose body 10; prevent weighing down subassembly 30 includes winding axle 31, is equipped with three guide post 32 that do the distribution of equidistant angle annular array around its axis on the winding axle 31, and the cover has relative it to make gliding direction cap 33 on the guide post 32, and the direction cap 33 is embedded to have one end butt the elastomer 34 at the outer top that interior top, the other end of direction cap 33 supported guide post 32, the outer wall of guide post 32 is equipped with first spacing portion 35, the internal face of direction cap 33 is equipped with the spacing portion 36 of second that supports first spacing portion 35. Here, the elastic body 34 is a compression spring.

Further, the guide cap 33 has an insertion groove 37 on the outer top thereof, into which the metal hose body 10 is wound. Preferably, the bottom of the fitting groove 37 has a curved surface shape. The groove bottom of the embedding groove 37 is arranged in an arc surface shape, so that the metal hose main body 10 is prevented from slipping out from the edge after being embedded into the embedding groove, and the anti-slipping effect is achieved.
