Abstract
The utility model discloses a minor-diameter bent spherical adjusting device for an armour cable based on an elastic ring, and the device comprises a cable inlet and a cable outlet. A spherical cable-bending mechanism is disposed between the cable inlet and the cable outlet. The spherical cable-bending mechanism is formed in a mode that a fixed hemisphere is buckled on a movable hemisphere, and the junction surface rotation is formed between the two hemispheres. The junction surface rotation between the two hemispheres is that the junction surface of the fixed hemisphere is provided with a radial slot, the junction surface of the movable hemisphere is provided with a bulge loop, the periphery of the bulge loop is provided with the elastic ring, and the elastic ring is disposed in the radial slot and fixed with the bulge loop. The junction surfaces of the fixed and movable hemispheres are respectively provided with a collision bead. The device, which employs the above technical scheme, is low in cost, is simple in structure, is convenient to use, and can achieve the bending of the armour cable or other types of cables in a range from 0 to 90 degrees.
Description
Technical field
The utility model relates to the accessory for cable.Specifically, the utility model relates to the adjustable connector for changing cable direction.
Background technology
Armoured cable is widely used in various application.They are particularly suited for requiring electric wire and the isolated application scenario of surrounding environment.The structure of these cables can be used in them to can be rated as dangerous place, and the place being safe from danger.Conventionally, in hazardous area, electric wire wiring is used rigid metal conduit.But, if applicable electrical code allows, can replace rigid conduit 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 this shell protection is extended is therein avoided wearing and tearing, shock etc.In addition, metal shell make cable can be in its whole length ground connection.Conventionally with outer plastic or rubber sheath covering metal shell, thus for cable increases waterproofing protection, and protection metallic sheath is avoided corrosion factor.Install although armoured cable specific rigidity pipeline more has flexibility and is easier to, its bending radius makes it be difficult to form tight bending, and therefore installs and need elbow or other adapter in some occasion.
In the past, use the accessory (for example, being connected to the stretch bending head of straight accessory) of different authentications or 90 degree that short single 90 degree accessories complete armoured cable bending.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 is expensive and inconvenient.
Thereby, the change armoured cable direction that need to install fast and conveniently and the accessory of other type cable direction.Also need to make armoured cable bending adjustable connector for armouring and other type cable within the scope of 0-90 degree at least.
The patent No. is 200910134775.7 utility model patent, has also proposed a kind of method, but this cable angle adjustment connector complex structure, and cost is expensive and inconvenient, can not effectively realize the angular adjustment of armoured cable.
Utility model content
The purpose of this utility model is to provide a kind of spherical rotational connector of simple in structure, cable angular adjustment that cost is low.
For achieving the above object, the utility model is by the following technical solutions:
The bending spherical adjusting device of armoured cable minor diameter based on elastic ring, it comprises cable inlet pipe mouth and cable outlet spout, and spherical cable bend mechanism is set 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 rotation between two hemispheres; Between described two hemispheres, establishing faying face rotation refers to: the faying face place of fixing hemisphere arranges radial slot, and the faying face place of movable hemisphere arranges bulge loop, and bulge loop periphery is elastic ring, and elastic ring is placed in radial slot and fixes with bulge loop.
On described two hemispheres faying face, establish collision bead.
Faying face between described two hemispheres and cable inlet pipe mouth, the cable outlet spout angle between is axially 30 °--60 °.
The utility model that adopts technique scheme, cost is low, simple in structure, easy to use, can realize armoured cable or the bending of other types cable within the scope of 0-90 degree.
Accompanying drawing explanation
Fig. 1 is shape assumption diagram of the present utility model.
Fig. 2 is that the utility model is along the axial cutaway view of cable tube.
Embodiment
As shown in Figure 1 and Figure 2, the bending spherical adjusting device of a kind of armoured cable minor diameter based on elastic ring, it comprises cable inlet pipe mouth 1 and cable outlet spout 2, and spherical cable bend mechanism is set 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 rotation between two hemispheres.
Between two hemispheres, establishing faying face rotation refers to: the faying face place of fixing hemisphere 3 arranges radial slot 15, and the faying face place of movable hemisphere 4 arranges bulge loop 6, and bulge loop 6 peripheries are elastic rings 16, and elastic ring 16 is placed in radial slot 15 fixing with bulge loop 6.
It should be noted that, above-mentioned faying face is the annular disk of middle perforate.The angle of faying face between two hemispheres and cable inlet pipe mouth 1, cable outlet spout 2 between is axially 30 °--60 °, can think any one in 30 °, 40 °, 45 °, 50 °, 60 °.
On described two hemispheres faying face, establish collision bead 8.
Operation principle of the present utility model is: armoured cable is inserted to cable inlet pipe mouth 1 and cable outlet spout 2, and rotary moveable hemisphere 4, rotates suitable angle according to the angle of required cable bend, can obtain the armoured cable after bending.
