Abstract

The utility model relates to an inhaul-cable joint ring consisting of a rubber filler block and a metal sleeve. The rubber filler block is provided with a groove adapted to the cavity of the metal sleeve and clamping the metal sleeve, wherein the metal sleeve is a conic annular body. When the inhaul-cable joint ring is subjected to a greater axial force in the cable-peg direction, the metal sleeve can not be pulled out from the rubber filler block, thus enabling a safe operation. The utility model has the advantages of simple structure, easy mechanical processing and low cost.

Description

A kind of cable connector ring

Technical field

The utility model relates to a kind of cable connector ring, especially relates to a kind of cable connector ring that is used to connect drag-line and swing arm.

Background technique

Being mechanically operated by at a distance by drag-line is mechanical field a kind of method commonly used, it mainly is connected in the swing arm by the cable connector ring by the end with drag-line, the other end of drag-line is connected on the operating handle, controls mechanism or the equipment that is connected with swing arm by the control operating handle.The cable connector ring plays the effect of transmission of drive force therein, should have ability that reduces certain rigid impulse and the ability of bearing certain axial force.Cable connector ring commonly used at present comprises the drag-line connecting rod, the annulus metallic sheath, the rubber pad, the metal lining, the swing arm pin, the rope pin, the rubber pad is set in outside the metal lining, offer block the only groove of this annulus metallic sheath parallel on the rubber pad with this metal lining, this annulus metallic sheath is fixedlyed connected with this drag-line connecting rod, when using this cable connector ring to connect drag-line and swing arm, the drag-line connecting rod is fixedlyed connected with an end of drag-line, this swing arm pin is the T font, offer the rope pin-and-hole on its perpendicular arm, its perpendicular arm passes attachment hole and the metal lining in the swing arm successively, its transverse arm card ends in swing arm, the rope pin passes this rope pin-and-hole metal lining and rubber pad is fixedly connected in this swing arm, thereby swing arm and the drag-line that is connected on this drag-line connecting rod are coupled together.This cable connector ring in the course of the work, when the power that this cable connector circulating application is added when drag-line or swing arm is not orthogonal to this swing arm pin, will produce along the axial force of this swing arm pin, if the direction of this axial force applies from rope pin direction, this metallic sheath near producing axial pulling-out force between end of this rope pin and the rubber pad, for safe in utilization, must guarantee that the cable connector ring can bear certain axial pulling-out force.Existing this cable connector ring, only there is the rope pin to replace the rubber pad owing to be positioned at the rubber pad of rope pin one side, and this annulus metallic sheath is fastened in the groove of annulus, have only with metallic sheath bear axial pulling-out force near area on the rubber pad of an end in contact of this rope pin, when this rope slocket ring is subjected to bigger axial pulling-out force, the metallic sheath of above-mentioned cable connector ring just can pull from the rubber pad.

The model utility content

The technical problems to be solved in the utility model provides a kind of cable connector ring that can bear bigger axial pulling-out force.

For solving the problems of the technologies described above, a kind of cable connector ring of the utility model comprises rubber pad and metallic sheath, offers corresponding with this metallic sheath inner chamber on this rubber pad and can block the only groove of this metallic sheath, and wherein, described metallic sheath is taper ring body type.

As a kind of improvement of the present utility model, wherein, the conical surface of described metallic sheath and the angle of its rotary middle spindle are that 15 degree are to 45 degree.

As a kind of improvement of the present utility model, wherein, the conical surface of described metallic sheath and the angle of its rotary middle spindle are 30 degree.

As a kind of improvement of the present utility model, wherein, described rubber pad is truncated cone shape, and the less end of the radial dimension of described groove closes on the less end of radial dimension of this rubber pad.

The utility model compared with prior art, a kind of cable connector ring of the utility model, because metallic sheath is taper ring body type, offer corresponding on the rubber pad and can block the only groove of metallic sheath with the metallic sheath inner chamber, when connecting drag-line and swing arm, the less end of radial dimension of metallic sheath is close to connect drag-line in the swing arm and swing arm links together, what make rubber pad and metallic sheath can both bear axial pulling-out force near the end in contact part of rope pin and the inner chamber contact segment of rubber pad and metallic sheath, the area that promptly bears axial pulling-out force has increased, therefore, when a kind of cable connector ring of the utility model is subjected to bigger during from axial force that rope pin direction applies, the metallic sheath of the utility model cable connector ring can not pull from the rubber pad, guaranteed safe in utilization, and it is simple in structure, machining is easy, and cost is low.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is that the master of a kind of cable connector ring of the utility model looks the sectional structure schematic representation.

Embodiment

See also Fig. 1, a kind of cable connector ring of the utility model comprises metallic sheath 1, drag-line connecting rod 7, rubber pad 3, metal lining 2, swing arm pin 6, rope pin 5.

Metallic sheath 1 is taper ring body type, and the conical surface of this metallic sheath 1 and the angle of its rotary middle spindle are 30 degree, fixedly connected with drag-line connecting rod 7, and this drag-line connecting rod 7 can be fixedlyed connected with the push-and-pull cable wire; Rubber pad 3 is set in outside the metal lining 2 and with these metal lining 2 formation and closely cooperates; Rubber pad 3 is truncated cone shape, its center offer can block this metal lining 2 only should be altogether on offer the hole that card ends this metal lining 2, offer corresponding on its round platform outer surface and can block the only groove 30 of this metallic sheath 1 with the inner chamber of this metallic sheath 1, the less end of the radial dimension of this groove 30 closes on the less end of radial dimension of this rubber pad 3, this swing arm pin 6 is the T font, offer rope pin-and-hole 60 on its perpendicular arm, this rope pin 5 can insert this rope pin-and-hole 60 and form and closely cooperate, and its transverse arm can block only in swing arm 4.

When using a kind of cable connector ring of the utility model to connect drag-line and swing arm, drag-line connecting rod 7 is fixedlyed connected with an end of drag-line, in order to make the utility model can bear bigger axial pulling-out force, the less end of radial dimension of this metallic sheath 1 is close in this swing arm 6, make rubber pad 3 and the end in contact part and the rubber pad 3 near this rope pin 5 of metallic sheath 1 can both bear axial pulling-out force with the inner chamber contact segment of this metallic sheath 1, the perpendicular arm of this swing arm pin 6 can pass the attachment hole in the swing arm and the inner chamber of metal lining 2 successively, then with in the rope pin-and-hole 60 on the perpendicular arm of rope pin 5 these swing arm pins 6 of insertion, metal lining 2 and rubber pad 3 are fixedly connected in this swing arm 4, thereby swing arm 4 and the drag-line that is connected on this drag-line connecting rod 7 are coupled together.

Certainly, the conical surface of this metallic sheath 1 and the angle of its rotary middle spindle are not limited to 30 degree, also can be that 15 degree are to 45 degree.
