Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.
As shown in fig. 1-5, the cable with strong pressure resistance and wear resistance comprises a circular-tube-shaped outer sheath 1, a plurality of rolling grooves 7 are embedded in the outer wall of the outer sheath 1, balls 6 are installed in the rolling grooves 7 in a rolling manner, the balls 6 protrude out of the outer surface of the outer sheath 1, the rolling grooves 7 are divided into a plurality of groups, the intervals of the rolling grooves 7 in adjacent groups are equal, and each group of rolling grooves 7 is six and is annularly arrayed around the central line of the outer sheath 1. The ball 6 can support the protection sleeve 1, and in the using process, the friction damage caused by dragging the cable can be effectively reduced. Effectively prolong the service life of the cable and improve the safety. The balls 6 may be spherical, cylindrical or other shapes that are easy to roll in practice.
The inner wall of the outer sheath 1 is connected with a plurality of strip-shaped air cavities 9, the bottoms of the rolling grooves 7 are located in one of the air cavities 9, the air cavities 9 are arranged in an annular array around the central line of the outer sheath 1, the two ends of the air cavities 9 are end faces 3, the end faces 3 are perpendicular to the inner wall of the outer sheath 1, and a gap is reserved between every two adjacent air cavities 9 along the axial direction of the outer sheath 1 to form a connecting cavity 8. Air cavity 9 can play the effect of buffering, reduces the cable damage that local pressure too big caused to rolling groove 7 is pressed close to air cavity 9 and is set up and to be reduced the too big damage that causes the cable of ball 6 atress. The setting of joint chamber 8 makes and to break off the cable and can avoid the destruction to air cavity 9 in joint chamber 8 punishment, and in practical application, correspond joint chamber 8 department and can set up annular mark line and mark the position of joint chamber 8 on outer sheath 1 to be convenient for find the position of joint chamber 8 and divide absolutely the cable.
