Cable anti-damage wall-penetrating bushing protector

Abstract

The invention discloses a cable anti-damage wall-penetrating bushing protector, and discloses a protection structure which combines a damping structure and an anti-abrasion structure into a whole, simplifies the structure and ensures the damping and anti-abrasion performance at the same time. Connecting sleeves are respectively screwed at one end of a main bushing, and a limiting plate is fixedlyarranged at the other end of the main bushing; the included angle between the limiting plate and the wall of the main sleeve is an acute angle, the limiting plate is fixedly arranged on the connectingsleeve, the included angle between the limiting plate and the wall of the connecting sleeve is an acute angle, the two fixing plates are symmetrically arranged on the limiting plate, a plurality of long-bar-shaped sliding grooves distributed at equal intervals are formed in the fixing plates; a plurality of pairs of guide hoops are arranged between the two fixing plates and correspond to the sliding grooves in a one-to-one mode, wherein each guide hoop is of an arc-shaped rod-shaped structure; an elastic pad is arranged on the arc-shaped concave face of each guide hoop, the two ends of each guide hoop are bent back to back in the vertical direction, and the two ends of each guide hoop are arranged in the corresponding sliding grooves through locking screws respectively.

Description

technical field [0001] The invention relates to an anti-damage wall-penetrating sleeve protector for cables, which relates to a sleeve protection structure for preventing cable damage when cables pass through walls in a shop, and belongs to the field of electric equipment. In particular, it relates to a protection structure which combines a shock absorbing structure and an anti-wear structure into one, and simplifies the structure while ensuring shock absorbing and anti-wear performances. Background technique [0002] The cable wall sleeve is a power construction auxiliary accessory used to separate the cables that need to pass through the wall from the wall, so as to avoid direct friction between the cable and the wall when passing through the wall. The cables are worn and damaged, but the traditionally used wall-through sleeves are in the form of straight tubes that are simply placed in the wall holes. For cables with large amplitudes, the sleeves and cables are prone to f...

[0002] The cable wall sleeve is a power construction auxiliary accessory used to separate the cables that need to pass through the wall from the wall, so as to avoid direct friction between the cable and the wall when passing through the wall. The cables are worn and damaged, but the traditionally used wall-through sleeves are in the form of straight tubes that are simply placed in the wall holes. For cables with large amplitudes, the sleeves and cables are prone to friction and wear , and the vibration generated by the cable cannot be damped and buffered, resulting in serious wear between the cable and the wall sleeve. The structure is separated from each other, resulting in the clamping position of the shock-absorbing structure to the cable is still prone to wear and tear

[0003] Notification No. CN109103824A discloses a wear-resistant wall-penetrating connection device for power cables. The connection device is a hollow cylinder inside, and the connection device is sequentially provided with elastic first parts coaxial with the connection device from the inside to the outside. A rubber layer and a second rubber layer; four telescopic rods are arranged between the two ends of the first rubber layer and the second rubber layer, and the telescopic rods adjust the first rubber layer, the second rubber layer and the second rubber layer through stretching. The distance between the rubber layer and the connecting device; the cable passes through the first rubber layer, and the diameter of the first rubber layer is adjusted by adjusting the length of the telescopic rod, so that the cable is fixed in the first rubber layer; the first rubber layer and the second rubber layer The distance between the two rubber layers is not less than one-half of the diameter of the cable; there are several first spring rods connected between the second rubber layer and the connecting device, and the device is protected against wear through the rubber layer, but the cable The friction between the rubber layer and the rubber layer is still sliding friction, and the friction force that causes wear is relatively large, resulting in limited anti-wear effect
