一种电缆穿管保护器
摘要：
本发明涉及一种电缆穿管保护器，包括碗型外套、滚珠、顶丝，碗型外套的扩口一侧的套口圆周设有若干个滚珠，滚珠外沿高出碗型外套的端面，碗型外套收口一侧的套壁端面上设有用于插接电缆保护管的环槽，电缆保护管由圆周布置的顶丝紧固，碗型外套整体分为若干块分体，每块分体的套口两端设有定位板，滚珠通过定位杆固定在定位板上。本发明的滚珠滚动灵活，滚动方向与电缆穿线方向一致，在电缆穿管过程中避免电缆与保护管端面直接接触，使电缆顺利穿过，避免电缆划伤，对电缆起到保护作用。多块分体结构可适用于多种电缆保护管管径，适用范围广，安装、拆卸方便。
摘要（英）：

The present invention relates to a cable pipe-through protector. The cable pipe-through protector comprises a bowl-type outer sleeve, balls and top threads. The plurality of are arranged at the circumference of a looping at one side of an expanding port of the bowl-type outer sleeve, the outer edges of the balls are higher than the end face of the bowl-type outer sleeve, the end face of a sleevingwall of one side of a closing port of the bowl-type outer sleeve is provided with a circular groove configured to insert a cable protection pipe, the cable protection pipe is fastened by the top threads arranged in a circumference mode, the whole body of the bowl-type outer sleeve is divided into a plurality of parts, the two end of the looping of each part are provided with location plates, andthe balls are fixed on the location plates through location rods. The balls are flexible to roll, the rolling directions of the balls are consistent to the cable threading direction, it is avoided that the cable is in direct contact with the end surface of the protection pipe in the cable pipe-through process to allow the cable to smoothly pass through so as to prevent the cable from being scratched and have a protection effect on the cable. The multi-part structure is suitable for pipe diameters of a plurality of cable protection pipes, and is wide in application range and convenient to mountand dismount.
