In order to achieve the above purpose, the utility model adopts the technical scheme that: the submarine cable bending limiter comprises two symmetrical half pipe bodies, the axis of the limiter is arranged on the splicing surfaces of the two half pipe bodies, each half pipe body comprises a first half pipe and a second half pipe coaxially arranged with the first half pipe, the inner diameter of each second half pipe is larger than that of each first half pipe, and a bending space is formed between the semi-cylindrical surface where the inner side wall of each first half pipe is located and the inner side wall of each second half pipe.
In another optimized scheme, the second half pipe comprises a conical half pipe in a frustum shape and a cylindrical half pipe with a closed edge.
According to another optimization scheme, a first deformation hole for improving deformation is formed in the conical half pipe.
In another optimized scheme, a second deformation hole for improving deformation is formed in the cylindrical half pipe.
According to another optimized scheme, one end face of the limiter is provided with a positioning pin, the other end face of the limiter is provided with a positioning hole, and the projection of the positioning pin on the other end face is rotated by 90 degrees and then is overlapped with the positioning hole.
According to another optimized scheme, the positioning hole is located on the end face of the first half pipe, and the positioning pin is located on the end face of the second half pipe.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages: form crooked space between the half cylinder at the inside wall place of first half pipe and the inside wall of the half pipe of second, can provide great crooked space for the cable, but guaranteed crooked limit, can be better play the guard action, the locating pin and the locating hole at limiter both ends can realize connecting between the limiter and use and restricted the relative rotation between the limiter simultaneously, and can realize the spacing joint of the half pipe body of concatenation, further enlarge protection length, and convenient for connection.
