Description

Technical Field

[0001] The utility model relates to the technical field of optical cable detection, in particular to an outdoor optical cable repeated bending detection device. Background Art

[0002] Optical cable is a soft and strong telecommunication transmission cable composed of one or more glass or plastic fibers. These fibers usually transmit information optically. Optical cables are widely used in communications such as telephone, Internet, television, and many other applications. Optical cables can transmit extremely high bandwidth and support the transmission of large amounts of data. Therefore, they are widely used in high-speed Internet, digital television and other fields. The optical fibers of optical cables have low signal attenuation and can transmit signals over long distances without being affected by obvious signal attenuation. Compared with traditional copper cables, optical cables have better resistance to electromagnetic interference and lightning. Optical cables are lighter and more flexible than copper cables, making them easier to lay and maintain. Since optical cables do not transmit current and have no electromagnetic fields, they are not prone to fire and will not cause electric shock. The main components of optical cables are optical fibers, cladding, insulation layer, metal sheath, outer sheath and core identification. The continuous development and innovation of optical cables have promoted the advancement of modern communication technology, making high-speed, high-bandwidth and low-loss data transmission possible.

[0003] Since some optical cables are used outdoors and may need to be bent during use, in order to ensure the quality of the optical cables, the optical cables need to be subjected to repeated bending tests during the production process to ensure that there will be no quality problems when the optical cables are used outdoors. The existing outdoor optical cable repeated bending detection device only performs bending detection on a certain point of the optical cable, and cannot perform bending detection on multiple positions of the optical cable at the same time, and the detection accuracy is low. Therefore, we propose an outdoor optical cable repeated bending detection device to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0027] Reference Figure 1-Figure 4 The utility model provides a technical solution: an outdoor optical cable repeated bending detection device, including a detection platform 1 and a push rod 4, the side wall of the detection platform 1 is fixedly connected with a motor 5, and a detection mechanism 2 is arranged on the detection platform 1, and the detection mechanism 2 includes a screw rod 201, a limit rod 202, a slider 203 and a transmission belt 204, and the screw rod 201 is rotatably connected to the detection platform 1 through a bearing, and one of the screw rods 201 is connected to the output end of the motor 5.

The transmission belt 204 is transmission-connected to two adjacent screw rods 201, and the screw rods 201, the limit rods 202 and the slider 203 are each provided with three. One end of the screw rod 201 is fixedly connected to a rotating shaft 205, and the rotating shaft 205 is rotationally connected to the detection platform 1, one of the rotating shafts 205 is fixedly connected to the output end of the motor 5, and the outer wall of the rotating shaft 205 is fixedly connected to a pulley 206, and the transmission belt 204 is transmission-connected to two adjacent pulleys 206.

[0029] By starting the motor 5, the output end of the motor 5 drives the rotating shaft 205 to rotate, and under the transmission of the pulley 206 and the transmission belt 204, the three screw rods 201 are driven to rotate. Under the restriction of the limit rod 202, the slider 203 moves back and forth along the limit rod 202, and then the optical cable is repeatedly bent by the push rod 4. The movement of the three sliders 203 can perform bending detection on multiple locations of the optical cable, thereby improving the detection accuracy. The screw rods 201 on both sides have opposite rotation directions to the middle screw rod 201. Therefore, when the push rods 4 on both sides push the optical cable to bend in a certain direction, the middle push rod 4 will push the optical cable to bend in the opposite direction.

[0030] In a preferred embodiment, a limiting groove 6 is provided on the push rod 4 . The limiting groove 6 is arranged in an arc shape. The limiting groove 6 is used to limit the optical cable so that the optical cable can slide out from between the two push rods 4 .

[0034] Specifically, the working process or working principle of the outdoor optical cable repeated bending detection device is as follows: the staff passes the optical cable through the two clamps 305, starts the cylinder 302, and the telescopic end of the cylinder 302 drives the fixed rod 303 to move, and the fixed rod 303 drives the two sliding blocks 307 to approach each other along the fixed rod 303, and the sliding blocks 307 drive the first fixed plate 308 and the second fixed plate 309 to rotate, thereby driving the two brackets 304 to approach each other, thereby driving the rubber pads 306 on the inner side of the two clamps 305 to contact the optical cable, clamping and fixing the optical cable, and then passing it through the two push rods 4 of the three groups in turn, and placing the optical cable in the limit groove 6, and then fixing the other end of the optical cable.
