Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a surface damage detection device for cable production. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. The outer surface of the cable is generally covered with an insulating protective layer. Most cables are installed outdoors through brackets. The outdoor environment is very harsh. Cables are easily blown by strong winds, causing the outer protective layer to wear or be scratched by external forces, affecting the transmission of electric energy or signals. In order to ensure the stable operation of outdoor equipment, it is usually necessary to perform flaw detection on the cables used by the equipment after a period of time.

[0003] Publication No. CN217304968U discloses a rapid detection device for cable surface damage, including a shell with a through hole, a detection component with a display and a probe, and clamps arranged at both ends of the shell, the probe is arranged on the inner wall of the through hole and faces the axis of the through hole, and the clamp includes a detachable three-jaw chuck arranged at the end of the shell, and the axes of the two three-jaw chucks coincide with the axis of the through hole. Although this surface damage detection device solves the problem of accurate flaw detection of cables under the premise of low-cost manufacturing of flaw detection equipment in related technologies, this surface damage detection device relies on electrically connected probes and displays to detect damage on the cable surface, and may not be able to fully identify minor damage or defects, and this surface damage detection device has limitations in the visual identification of damage, especially for those minor damages that require careful observation to be discovered. Therefore, improvements are needed. Utility Model Content

[0013] 1. In the utility model, when actually used, the cable is placed in the housing, and then the cable is centered by the claws, and then the cable can be inspected by the probe, and the staff can also observe the cable with the naked eye through the first magnifying glass, so that the accuracy of the flaw detection can be guaranteed to the maximum extent. If a problem is found, the staff can also rotate the connecting plate by the push handle, and the connecting plate is then rotated by the rotating rod, and the connecting plate then drives the second magnifying glass to rotate. After rotating ninety degrees, the magnet can resist the first stopper, and the second magnifying glass is located on the first magnifying glass. At this time, the cable can be observed more carefully by superimposing the first magnifying glass and the second magnifying glass, and the magnet can also absorb the first stopper made of ferrite stainless steel due to the effect of magnetic force. At this time, the position of the second magnifying glass can be limited, and the second magnifying glass can be closed by rotating the second magnifying glass ninety degrees in the opposite direction. The second magnifying glass is raised, and at this time the magnet can press against and attract the second stopper, and the second magnifying glass can be limited at this time. The utility model provides a preliminary magnified observation of the cable surface through the first magnifying glass, and the foldable second magnifying glass can be rotated to the first magnifying glass as needed to achieve double magnification. This design allows the operator to observe the slight damage or defects on the cable surface more clearly, thereby improving the accuracy and efficiency of detection. Moreover, through the design of the foldable second magnifying glass, the operator can choose whether to use double magnification according to the size and nature of the damage on the cable surface. This flexibility enables the device to adapt to various detection needs, thereby improving the practicability of the device. At the same time, this purely mechanical amplification mechanism does not require power supply or complex electronic systems, reduces the complexity and cost of the device, and also reduces maintenance requirements, and has high practicability.

[0014] 2. In the present invention, in actual use, the present invention can be conveniently moved by rollers. When there are obstacles such as stones on the road surface, the staff only needs to twist the screw rod. At this time, since the inside of the mounting plate is provided with threads, the screw rod can move inside the mounting plate. The screw rod then drives the bottom plate and the protective plate to move until the protective plate falls. At this time, the protective plate can push away obstacles such as stones in the direction of travel, thereby avoiding hitting the moving seat and the rollers, thereby ensuring the stability of movement. The structure is simple, the cost is low, and the practicality is high. BRIEF DESCRIPTION OF THE DRAWINGS
