Abstract
The invention discloses a combined threading device capable of clamping construction wires. The combined threading device is characterized in that one end of an outer clamping sleeve is sealed and fixedly provided with a pull ring at the center, the other end of the outer clamping sleeve is open, a first thread is arranged on the inner surface of the wall of the outer clamping sleeve, one end of an inner lining sleeve is sealed to form a sealed end, the other end of the inner lining sleeve is open to form an open end, a second thread is arranged on the outer surface of the wall of the inner lining sleeve, the wall of the inner lining sleeve and the wall of the outer clamping sleeve are connected, a central clamping column is fixed at the center of the inner cavity of the inner lining sleeve, the whole inner cavity of the inner lining sleeve is of an equal-diameter cylindrical shape, the thickness of the wall of the inner lining sleeve gradually increases from the sealed end of the inner lining sleeve to the open end of the inner lining sleeve, and notches are evenly formed in the sleeve wall at the open end of the inner lining sleeve along the circumferential direction of the sleeve wall. The combined threading device has the advantages that a two-layer-sleeve structure is used, the outer clamping sleeve clamps the inner lining sleeve, connection can be achieved conveniently and reliably, project construction efficiency is increased, and threading is facilitated.
Description
Technical field
The present invention relates to construction engineering technical field, more specifically, relate to the threader of a kind of combined type clamping construction line.
Background technology
In building operations, often need to carry out threading operation, namely in the duct various line for building or reinforcing bar (line of namely constructing) are connected, in construction, often adopt the external equipment such as hoist engine, strand pulling machine to carry out.Need to clamp in one end of various line to be connected or reinforcing bar, to make various line or reinforcing bar firmly be connected with external equipment, enough external force could be kept in whole threading process to draw.The construction line connected once disposable or number of steel bars more, will produce relative slip between each construction line or reinforcing bar, simple fastening structure very easily causes connection loosely, makes troubles to threading, such as broken string, slippage, upper power inconvenience etc. problem.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of combined type to clamp the threader of construction line, be intended to quickly and easily construction line to be compiled and restraint, and can convenient connection and running through.
Technical purpose of the present invention is achieved by following technical proposals:
A threader for combined type clamping construction line, comprises outer clip sleeve and liner sleeve, wherein:
One end of described outer clip sleeve is closed and is fixedly installed draw ring in middle position, the other end opening of outer clip sleeve, and arrange the first screw thread at the inner surface of external jacket cylinder barrel, the inner chamber of described outer clip sleeve is the cylindrical shape of equal diameter;
One end of described liner sleeve is closed and is formed blind end, other end opening forms openend, the external surface of liner sleeve wall arranges the second screw thread, described second screw thread and the first screw thread match, to make liner sleeve wall be connected with outer clip sleeve wall, and the blind end of liner sleeve is coaxially arranged in the inner chamber of outer clip sleeve; Central clamping column is fixedly installed in the middle position of neck bush tube inner chamber, the inner chamber integrated upper cylindrical shape for equal diameter of described liner sleeve, by liner sleeve blind end to openend, liner sleeve wall increases gradually, and on the barrel of liner sleeve openend, along barrel circumferencial direction, evenly gap is set.
In technique scheme, the quantity of described gap is 3 or 4.
In technique scheme, the drift angle of described gap is 10-15 degree.
Compared with prior art, technical scheme of the present invention adopts the structure of two-layer sleeve, the internal lining cylinder of outer clip sleeve is utilized to implement clamping, reduce gradually to make the space between liner sleeve wall and central clamping column, to realize the fixing of line of constructing in sleeve, namely by screwing outer clip sleeve, extruding liner sleeve wall inwardly shrinks, owing to arranging gap at the barrel of liner sleeve openend, the barrel receiving extruding will radially inwardly shrink, clamp the construction line be arranged between barrel and central clamping column, to realize the fixing of connection.In actual use, only need to screw outer clip sleeve and can realize easily and reliably connecting, improve engineering construction efficiency, facilitate threading.

Fig. 3 is the structural representation of liner sleeve in the present invention.
Wherein 1 is draw ring, and 2 is outer clip sleeve, and 3 is outer clip sleeve wall, and 4 is the first screw thread, and 5 is liner sleeve, and 6 is central clamping column, and 7 is liner sleeve wall, and 8 is the second screw thread, and 9 is gap.
Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with specific embodiment.
Three figure as shown in accompanying drawing 1-3 are respectively sectional view of the present invention, the elevation of lateral view and liner sleeve, and the threader of a kind of combined type clamping of the present invention construction line, comprises outer clip sleeve and liner sleeve, wherein:
One end of described outer clip sleeve is closed and is fixedly installed draw ring in middle position, the other end opening of outer clip sleeve, and arrange the first screw thread at the inner surface of external jacket cylinder barrel, the inner chamber of described outer clip sleeve is the cylindrical shape of equal diameter;
One end of described liner sleeve is closed and is formed blind end, other end opening forms openend, the external surface of liner sleeve wall arranges the second screw thread, described second screw thread and the first screw thread match, to make liner sleeve wall be connected with outer clip sleeve wall, and the blind end of liner sleeve is coaxially arranged in the inner chamber of outer clip sleeve; Central clamping column is fixedly installed in the middle position of neck bush tube inner chamber, the inner chamber integrated upper cylindrical shape for equal diameter of described liner sleeve, by liner sleeve blind end to openend, liner sleeve wall increases gradually, and on the barrel of liner sleeve openend, along barrel circumferencial direction, evenly gap is set.
In technique scheme, the quantity of described gap is 3 or 4, is shown as four in figure.
In technique scheme, the drift angle of described gap is 10-15 degree.
Compared with prior art, technical scheme of the present invention adopts the structure of two-layer sleeve, the internal lining cylinder of outer clip sleeve is utilized to implement clamping, reduce gradually to make the space between liner sleeve wall and central clamping column, to realize the fixing of line of constructing in sleeve, namely by screwing outer clip sleeve, extruding liner sleeve wall inwardly shrinks, owing to arranging gap at the barrel of liner sleeve openend, the barrel receiving extruding will radially inwardly shrink, clamp the construction line be arranged between barrel and central clamping column, to realize the fixing of connection.In actual use, only need to screw outer clip sleeve and can realize easily and reliably connecting, improve engineering construction efficiency, facilitate threading.
Above to invention has been exemplary description; should be noted that; when not departing from core of the present invention, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into protection scope of the present invention.
