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
The present invention relates to the accessory for cable.Specifically, the present invention relates to the adjustable connector for changing cable direction.
Background technology
Armoured cable is widely used in various application.They are particularly suited for the application scenario requiring electric wire and ambient environment.The structure of these cables makes them can be used in can be rated as dangerous place, and the place be safe from danger.Usually, in hazardous area, electric wire wiring uses rigid metal conduit.But, if applicable electrical code allows, rigid conduit can be replaced with flexible armoured cable.Generally speaking, rigid conduit installs more difficult than armoured cable and cost is higher.Therefore, as long as electrical code allows, user prefers to use armoured cable.
Armoured cable generally includes conductive flexible metal shell, and the conductor that the protection of this shell extends wherein is from wearing and tearing, shock etc.In addition, metal shell enables cable ground connection over the whole length.Usually with outer plastic or rubber sheath covering metal shell, thus for cable increases waterproofing protection, and protection metallic sheath is from corrosion factor.Although armoured cable specific rigidity pipeline more has flexibility and is easier to install, its bending radius makes it be difficult to form tight bending, and therefore needs elbow or other adapter in the installation of some occasion.
In the past, the accessory of different certifications (such as, being connected to the stretch bending head of straight accessory) or short single 90 degree of accessories are used to bend to 90 degree that complete armoured cable.Similarly, also can use the accessory for other angle of bend, so need user library to have the accessory of various different angles.It is found that such cost intensive and inconvenient.
Thus, the accessory in change armoured cable direction and other type cable direction that can install fast and is conveniently needed.Also need to make armoured cable bending adjustable connector for armouring and other type cable within the scope of at least 0-90 degree.
The patent No. is the patent of invention of 200910134775.7, it is also proposed a kind of method, but this cable angle adjustment connector complex structure, and cost intensive and inconvenient, effectively can not realize the angular adjustment of armoured cable.
Summary of the invention
The object of the present invention is to provide the spherical rotational connector of the cable angular adjustment that a kind of structure is simple, cost is low.
For achieving the above object, the present invention is by the following technical solutions:
Armoured cable minor diameter based on double convex ring bends a spherical adjusting device, and it comprises cable inlet pipe mouth and cable outlet spout, arranges spherical cable bend mechanism between described cable inlet pipe mouth and cable outlet spout; Described spherical cable bend mechanism is: a fixing hemisphere is fastened on a movable hemisphere, establishes faying face to rotate between two hemispheres; Establish faying face to rotate between described two hemispheres to refer to: fixing hemisphere arranges bulge loop I at faying face place, and movable hemisphere arranges bulge loop II at faying face place, two bulge loop overcoat annular flute profile clips.
Described two hemispheres faying face establishes collision bead.
Faying face between described two hemispheres and cable inlet pipe mouth, cable outlet spout axially between angle be 30 °--60 °.
Adopt the present invention of technique scheme, cost is low, and structure is simple, easy to use, can realize armoured cable or other types cable bending within the scope of 0-90 degree.
Accompanying drawing explanation
Fig. 1 is shape assumption diagram of the present invention.
Fig. 2 is the cutaway view of the present invention along cable tube axis.
Embodiment
As shown in Figure 1 and Figure 2, a kind of armoured cable minor diameter based on double convex ring bends spherical adjusting device, and it comprises cable inlet pipe mouth 1 and cable outlet spout 2, arranges spherical cable bend mechanism between described cable inlet pipe mouth 1 and cable outlet spout 2; Described spherical cable bend mechanism is: a fixing hemisphere 3 is fastened on a movable hemisphere 4, establishes faying face to rotate between two hemispheres.
Establish faying face to rotate between two hemispheres to refer to: fixing hemisphere 3 arranges bulge loop I26 at faying face place, and movable hemisphere 4 arranges bulge loop II25 at faying face place, two bulge loop overcoat annular flute profile clips 27.
It should be noted that, above-mentioned faying face is the annular disk of central aperture.Faying face between two hemispheres and cable inlet pipe mouth 1, cable outlet spout 2 axially between angle be 30 °--60 °, can think in 30 °, 40 °, 45 °, 50 °, 60 ° any one.
Described two hemispheres faying face establishes collision bead 8.
Operation principle of the present invention is: armoured cable is inserted cable inlet pipe mouth 1 and cable outlet spout 2, rotary moveable hemisphere 4, rotate suitable angle according to the angle of required cable bend, can obtain the armoured cable after bending.
