Abstract

The utility model relates to a rope fixing structure. The rope fixing structure is characterized in that one end of a fixing end is provided with a cylindrical working section, wherein the working section is provided with a U-shaped notch which is used for dividing the working section into two overhanging arms and clamping a rope, the two overhanging arms axially extend, the working section is rotatably provided with a thread sleeve through an external thread arranged on the periphery of the working section, and the thread sleeve is used for blocking the rope. When the rope fixing structure is in use, the middle part of the rope is clamped between the two overhanging arms of the rope fixing structure, the thread sleeve is screwed on the working end of the fixing end to block the rope in the U-shaped notch, the thread sleeve is only used for blocking the rope, and can not lock the rope at the fixing end, the rope can move relative to the fixing end, when the rope fixing structure is applied to the test of a pulling-out connector, once a pulling-out rope is connected with the fixing end, the pulling-out rope and the fixing end can not be automatically separated from each other, compared with the prior art, the working efficiency is improved, the stress point of the pulling-out rope can be automatically adjusted relative to the fixing end, the stress of the components of the pulling-out connector is uniform, and the testing effect is good.

Description

A kind of rope fixing structure

Technical field

The utility model relates to a kind of rope fixing structure of being connected with the intermediate portion of the fixing rope in two ends of being used for, and belongs to a kind of mechanical connecting structure.

Background technique

Existing a kind of Connector assembly that pulls, the plug and socket of this Connector assembly separates by force by pulling force, its socket rear end has the rope of pulling, these two ends that pull rope are separately fixed on the socket, when the plug and socket of Connector assembly need separate, apply pulling force between plug and socket both are separated, the power that applies on socket is finished by pulling rope.The Separating force that pulls connector is the important performance indexes that pulls connector, in the testing process of connector, need to detect pulling-out force, in existing a kind of test by hook catch on pulling the rope apply pulling force to Connector assembly, detect in this way, pull the rope with hook between be connected very convenient, fetch one group of Connector assembly will pull the rope collude on hook and can detect, it is also very easy to take off Connector assembly from hook, but, pull and combine defective tightness between rope and the hook, at the beginning of test, when also not on plug during the application of force, pull rope and be in relaxed state, and the general rope that pulls all is a wire rope, and the pliability of wire rope is not very good, and is not enough so that pull rope and be attached on the hook, be easy to break away from so pull rope, give test arrival trouble with hook.

The model utility content

The purpose of this utility model is to provide a kind of and is connected reliable rope fixing structure with the rope that pulls that pulls Connector assembly.

For achieving the above object, the utility model adopts following technological scheme: a kind of rope fixing structure, comprise fixedly termination, fixedly an end of termination has columned active section, active section has the U-shaped breach that is used to snap in rope that it is divided into axially extended two overhang, and active section is provided with the swivel nut of the rope that is used to block by the external thread rotary that is provided with on its outer circumferential face.

Fill out in the described U-shaped breach and be provided with the supporting element that prevents that two overhang from drawing in.

Described supporting element is cylindrical, and supporting element is filled out and is located in the U-shaped breach by being separately positioned on two axially extended arc notch on the overhang opposed inside face, and the arc notch of two overhang all coincide with the outer circumferential face of supporting element and cooperates.

The outer end of described supporting element is wholely set the block termination that interior edge face cooperates with the fixing end face roof pressure of termination, and the shutoff that is provided with on the exterior edge face of block termination and the swivel nut end face cooperates along block.

The active section of fixedly termination of the present utility model is divided into axially extended two overhang by the U-shaped breach, the intermediate portion of rope can be stuck between two overhang, and screw swivel nut in the fixing working end of termination, swivel nut is blocked rope and is made that in the U-shaped breach rope can not be by deviating from the U-shaped breach, because swivel nut only is the rope of blocking, rope can be locked at fixedly on the termination, rope can move with respect to fixing termination, when the utility model being applied in the test that pulls connector, in case pulling rope is connected with fixing termination, both just can not separate voluntarily, compared with prior art, improved working efficiency, and pulled rope and can adjust force bearing point automatically with respect to fixing termination, pull the stressed even of Connector assembly, good test effect.

Fill out in the U-shaped breach of fixedly termination of the present utility model and be provided with the supporting element that prevents that two overhang from drawing in, supporting element struts two overhang and prevent that two overhang from drawing under the effect of swivel nut, and then causes the inefficacy of fixed structure.

Description of drawings

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is the fixing structural representation of termination among Fig. 1.

Embodiment

A kind of rope fixing structure, in Fig. 1 ~ 2, this rope fixing structure comprises fixedly termination 1, fixedly an end of termination 1 is the fixed end that is used to bear pulling force, the other end has active section, active section integral body is cylindric, active section has the U-shaped breach of inwardly being cut by the termination 9, U-shaped breach 9 runs through the side face of active section, the U-shaped breach is divided into two overhang 8 with active section, two overhang 8 extend axially along active section, and rope 6 snaps in the U-shaped breach 9, and the U-shaped breach is all extended at the two ends of rope 6.The outer circumferential face of active section is provided with outside thread, and screw thread is installed with swivel nut 2 on the outer circumferential face of active section, and swivel nut 2 rope 6 of blocking can not be deviate from rope 6 by the port of U-shaped breach.

As the improvement of the foregoing description, the arc notch that is provided with on 10, two overhang 8 of arc notch on two overhang 8 opposed inside faces is positioned on the same cylndrical surface.Fill out in U-shaped breach 9 and be provided with supporting element 3, supporting element 3 is cylindric, and two arc notch 10 all coincide with the outer circumferential face of supporting element 3 and cooperate.

As improvement of the technical scheme, the outer end of supporting element 3 has been wholely set block termination 7, and the interior edge face of block termination 7 cooperates with the fixing end face roof pressure of termination 1.The end face of swivel nut 2 is provided with the shutoff that cooperates with the exterior edge face block of block termination 7 along 5.

As the improvement of the foregoing description, the outer circumferential face of swivel nut 2 is provided with the plane 4 for tool holding.

Supporting element in the foregoing description is cylindrical and is arranged in the U-shaped breach by being arranged on two arc notch on the overhang, and supporting element also can be and U-shaped breach the square of inserting that coincide.

When the rope fixing structure with present embodiment was applied in the pulling-out force test that pulls Connector assembly, rope laterally was stuck in the U-shaped breach with pulling, plug is established upper supporting piece and screwed on swivel nut and can realize rope anchor and pull being connected of rope.
