Embodiment Construction

[0015] like figure 1 , figure 2 As shown, a small-diameter curved spherical adjustment device for armored cables based on a double convex ring, it includes a cable inlet 1 and a cable outlet 2, and the cable inlet 1 and the cable outlet 2 A spherical cable bending mechanism is provided; the spherical cable bending mechanism is as follows: a fixed hemisphere 3 is buckled on a movable hemisphere 4, and a joint surface is provided between the two hemispheres to rotate.

[0016] The joint surface rotation between the two hemispheres means: the fixed hemisphere 3 is provided with a convex ring I26 at the joint surface, the movable hemisphere 4 is provided with a convex ring II25 at the joint surface, and the two convex rings are covered with an annular groove-shaped clamp 27.

[0017] It should be noted that the above-mentioned joint surface is an annular disk with a hole in the middle. The angle between the joint surface between the two hemispheres and the axis of the cable inl...

Abstract

The invention discloses a small-diameter bending spherical adjusting device for an armored cable based on double convex rings. The small-diameter bending spherical adjusting device comprises a cable tube inlet and a cable tube outlet, wherein a spherical cable bending mechanism is arranged between the cable tube inlet and the cable tube outlet; in the spherical cable bending mechanism, a fixed hemisphere is buckled on a movable hemisphere, and a joint face is arranged between the two hemispheres for rotating; the joint face arranged between the two hemispheres for rotating means that a convex ring I is arranged on the joint face of the fixed hemisphere, and a convex ring II is arranged on the joint face of the movable hemisphere; annular grooved hoops are sleeved outside the two convex rings; collision balls are arranged on the joint face of the two hemispheres. By adopting the technical scheme, the small-diameter bending spherical adjusting device has the advantages of low cost, simple structure and convenience in use; bending of the armored cable or other types of cables within 0-90 degrees can be realized.

Description

technical field [0001] The invention relates to accessories for cables. In particular, the present invention relates to adjustable connectors for changing the direction of cables. Background technique [0002] Armored cables are used in a wide variety of applications. They are especially suitable for applications requiring electrical insulation from the surrounding environment. The construction of these cables allows them to be used in locations that can be called hazardous, as well as locations that are not. Typically, rigid metal conduits are used for electrical wiring in hazardous locations. However, flexible armored cables may be used in place of rigid conduit if permitted by applicable electrical codes. In general, rigid conduit is more difficult and more expensive to install than armored cable. Therefore, users prefer to use armored cables whenever the electrical code allows. [0003] Armored cables typically include a conductive flexible metal jacket that protec...
