Abstract
The utility model provides a fastening dog for down-hole cable, relating to a detachable fastener which is clamped by friction. The utility model is characterized in that one end of a clamping body with a cable horizontal slot is connected with a movable door in axis, and the other end of the clamping body is provided with a hook-shaped locking slot; the other end of the movable door is connected in axis with a locking buckle which can be overlapped and connected with the clamping body; a diameter-variation face of a disc cam at the end part of the locking buckle is engaged with the hook-shaped locking slot; a cam axis is provided with a square core hole. The utility model has the notable advantages of convenient and rapid assembly and disassembly, tightness, reliability, strong integrity and the avoidance of the generation of down-hole object-falling.
Description
The utility model belongs to the detachable securing member of friction grip, particularly relates to the fastening clip of a kind of downhole cable.
The clip that is generally used for downhole cable all is made of 3 to 5 single-pieces, not only the installation or removal in production practices can not be convenient and swift, the more important thing is because the environment for use of down-hole complexity, easily get loose between each single-piece and cause trouble of lost tool in hole, influence the carrying out of ordinary production.
It is strong that the purpose of this utility model provides a kind of globality, and easy installation and removal is the fastening clip of downhole cable efficiently.
Above-mentioned purpose obtains by the following technical programs: card body 2 one ends that have cable hugging 3 are connected with 1 at valve, the card body other end is provided with and colludes shape locking slot 5, valve 1 other end axle connects and can be stacked with the snap close 6 that connects with the card body weight, the disc cam 4 reducing cards of snap close end engage with colluding the shape locking slot, and camshaft 4 ' is provided with square heart hole.
Below with drawings and Examples explanation the utility model.
Accompanying drawing 1, the utility model partial cutaway schematic.
Among the figure: 1 valve, 2 card bodies, 3 cable huggings, 4 cams, 4 ' camshaft, 5 collude the shape locking slot, 6 snap closes.
Embodiment as shown in the figure, card body 2, valve 1, snap close 6 three parts all be that axle connects, and the card body of opening the valve rear semicircle is fastened on the oil pipe, and the degree of depth of its cable hugging 3 can only make cable produce micro-elastic to be out of shape, but not suppresses cable.Shut valve and push away snap close 6 parts and make it and block body weight and be stacked with and connect, what disc cam 4 its base circle portion of snap close 6 ends of this moment were threaded to card body 2 ends colludes shape locking slot 5 one sides, camshaft 4 ' is provided with square heart hole, utilizing cubic spanner rotating cam that its reducing card is screwed in colludes in the shape locking slot, because the cam lift angle is much smaller than from the locking angle, therefore the big self-locking property of clamping force is good, the tight masterpiece of suppressing that rotating cam produces is used for oil pipe, makes shock resistance of this clip and skid resistance all be better than other locking mode.The cam of this clip places and colludes the shape locking slot, can avoid the operation cam deviate from by external force, and its reliability is comparatively outstanding.The more important thing is that each parts is strong through the riveted globality that is coupling, and can not produce trouble of lost tool in hole.
It is quick to the utlity model has easy installation and removal, fastening reliable, globality Can avoid producing the remarkable advantage of trouble of lost tool in hole by force.
