Abstract

The invention relates to a repeated bending test equipment of an optical cable, comprising a rack and a swinging rod, wherein the rack is provided with a motor; an output end of the motor is connected with a transmission device in a transmission manner; the side surface of the rack is provided with two bending testing wheels; the side surface of the rack is provided with a vertical sliding rail below the two bending testing wheels; the sliding rail is assembled with a counterweight sliding block which is provided with a lower clamp; the swinging end of the swinging rod is provided with an upper clamp; the transmission device comprises a crank sliding block mechanism; the sliding block of the crank sliding block mechanism is a strip-shaped sliding block, one side surface of which is provided with transmission teeth; the sliding block with teeth is meshed with a gear so as to form a gear rack transmission mechanism; and the swinging rod and the gear are fixedly connected into a whole along the radial direction of the gear. The motor drives a crank of the crank sliding block mechanism to rotate unidirectionally, the sliding block drives the gear to rotate in a reciprocating manner bytransmission teeth arranged thereon, and the swinging rod fixedly arranged on the gear outputs swinging. The motor can obtain swinging of the swinging rod without the need of positive rotation and negative rotation.

Description

technical field [0001] The invention relates to an optical cable repeated bending test equipment. Background technique [0002] With the start of 3G (3rd generation mobile communication) and FTTH (fiber-to-the-home), with the vigorous development of access network and customer premises network, and with the continuous decline in the price of optical receiving devices, the market for indoor optical cables has been steadily expanding year by year . Indoor optical cables are thin and soft, easy to install, weak in mechanical strength, and narrow in temperature range. Compared with outdoor optical cables, the requirements for mechanical properties such as tensile strength, lateral pressure resistance, and impact resistance are lower. However, the indoor space is small, there are many turns, and the bending probability is high, so the requirements for the repeated bending performance of indoor optical cables are higher. In order to make indoor optical cables suitable for norma...
