The utility model relates to a downhole double-tube cable fixer comprising a first split unit and a second split unit which are in symmetrical connection. A first arc concave surface A and a first arc concave surface B are arranged on the first split unit, and a second arc concave surface A and a second arc concave surface B are arranged on the second split unit. The downhole double-tube cable fixer is characterized in that a first mounting groove is arranged on the first arc concave surface A of the first split unit, and a first movable block is embedded in the first mounting groove; and a second mounting groove is arranged on the second arc concave surface A of the second split unit, and a second movable block is embedded in the second mounting groove. The first mounting groove and the second mounting groove are symmetrically arranged, and the inner side surfaces of the first movable block and the second movable block are arc surfaces with the same diameter. Tight-pressing screws are mounted on the first split unit and the second split unit respectively and are contacted with the outer side surfaces of the corresponding movable blocks. The two movable blocks are arranged on the two arc concave surfaces of a clamped oil tube and can be moved radially. By adjusting the movable blocks radially, the oil tube can be clamped by the two movable blocks, and requirement of fixing various oil tubes with different diameters can be met; and multiple functions are realized and manufacturing cost of a mould is reduced.

Background technique
In oil well operation, the underground double-pipe cable fixer is a kind of for being used for protective gear fixing and the protection cable.It is arranged on the oil pipe of down well placement, is installed on bypass tube simultaneously.Existing underground double-pipe cable fixer comprises symmetrical the first split and the second split that connects, the first split is provided with the first circular arc concave surface A and the first circular arc concave surface B, the second split is provided with the second circular arc concave surface A and the second circular arc concave surface B, in use, the first circular arc concave surface A and the second circular arc concave surface A hold tightly on oil pipe, and the first circular arc concave surface B and the second circular arc concave surface B hold tightly on bypass tube.This two-tube fixture in use exists a kind of dimensional structure to be only applicable to a kind of problem of oil pipe of diameter, need to design the two-tube cable fixer of different size structure for the oil pipe of different-diameter, causes die manufacturing cost to improve.
Summary of the invention
The utility model provides a kind of use of easy to adjust, the oil pipe that satisfies multiple diameter for solving the technical problem that exists in known technology, thereby reduces the underground double-pipe cable fixer of die manufacturing cost.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of underground double-pipe cable fixer, comprise symmetrical the first split and the second split that connects, the first split is provided with the first circular arc concave surface A and the first circular arc concave surface B, the second split is provided with the second circular arc concave surface A and the second circular arc concave surface B that coordinates respectively with the first circular arc concave surface A and the first circular arc concave surface B, it is characterized in that: be provided with the first mounting groove at the first circular arc concave surface A place in described the first split, be embedded with first movable block that can radially move in this mounting groove; Be provided with the second mounting groove at the second circular arc concave surface A place in described the second split, be embedded with second movable block that can radially move in this mounting groove, two mounting grooves are symmetrical arranged, and the inner side surface of two movable blocks is isometrical arc surface; Also be separately installed with a contacted housing screw of the outer side surface with corresponding movable block in two splits.
The technological scheme that the utility model can also be taked is:
The two ends of described the first movable block and the second movable block are equipped with positioning convex, are equipped with the slot that matches with corresponding positioning convex on the bi-side of described the first mounting groove and the second mounting groove.
Be equipped with several graduated scale timberlines that radially distribute on described the first movable block and on the second movable block.
Advantage and the good effect that the utlity model has are:
The utility model is by arranging two movable blocks that can radially move in the two arc surface positions that clamp oil pipe, by radially adjusting movable block, make two movable blocks clamp oil pipe and satisfy the fixedly requirement of the oil pipe of multiple diameter, thereby realized multi-use, reduced die manufacturing cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A place partial enlarged drawing in Fig. 1.
In figure: 1, the first split; 1-1, the first circular arc concave surface A; 1-2, the first circular arc concave surface B; 1-3, the first mounting groove; 2, the second split; 2-1, the second circular arc concave surface A; 2-2, the second circular arc concave surface B; 2-3, the second mounting groove; 3, the first movable block; 4, the second movable block.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1 and 2, a kind of underground double-pipe cable fixer, comprise symmetrical the first split 1 and the second split 2 that connects, the first split is provided with the first circular arc concave surface A1-1 and the first circular arc concave surface B1-2, and the second split is provided with the second circular arc concave surface A2-1 and the second circular arc concave surface B2-2 that coordinates respectively with the first circular arc concave surface A and the first circular arc concave surface B.Be provided with the first mounting groove 1-3 at the first circular arc concave surface A place in described the first split, be embedded with first movable block 3 that can radially move in this mounting groove.Be provided with the second mounting groove 2-3 at the second circular arc concave surface A place in described the second split, be embedded with second movable block 4, two mounting grooves that can radially move and be symmetrical arranged in this mounting groove, the inner side surface of two movable blocks is isometrical arc surface.Also be separately installed with a contacted housing screw of the outer side surface with corresponding movable block (housing screw does not show the place in the drawings) in two splits.Concrete, during the diameter that forms less than the first circular arc concave surface A and the second circular arc concave surface A when the diameter of oil pipe, adjust the amount of moving radially of movable block by adjusting housing screw, the inner arc face of two movable blocks is held tightly on the oil pipe of corresponding diameter.
In technique scheme: the two ends of two movable blocks and the two ends of each self-corresponding mounting groove can be adopted and be faced cooperating structure directly.For avoiding in the situation that misoperation, movable block is sliding from split vertically, movable block preferably adopts following structure with coordinating of mounting groove: the two ends of described the first movable block and the second movable block are equipped with positioning convex, are equipped with the slot that matches with corresponding positioning convex on the bi-side of described the first mounting groove and the second mounting groove.Adopt the cooperating structure of above-mentioned slot and projection, limited movable block movement vertically, i.e. the movement of tubing length direction.Thereby avoided movable block from axially skidding off, made the movable block only can be along the radially adjustment of oil pipe.
In technique scheme: be equipped with several graduated scale timberlines that radially distribute on described the first movable block and on the second movable block.Wherein, the oil pipe of the corresponding a kind of diameter of each graduated scale timberline.Carry out the position centering when adopting this graduated scale timberline to be convenient to install, can accelerate installation rate and save the installation time.
