Description
Technical field
The utility model relates to construction engineering technical field, more specifically, relates to jacket type construction line threading fastening devices.
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.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides jacket type to construct line threading fastening devices, is intended to quickly and easily construction line to be compiled and restrainted, and can convenient connection and running through.
Technical purpose of the present utility model is achieved by following technical proposals:
Jacket type construction line threading fastening devices, 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, the technical solution of the utility model 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (1);
Fig. 2 is structural representation of the present utility model (2);
Fig. 3 is the structural representation of liner sleeve in the utility model.
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
The technical solution of the utility model 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 utility model, the elevation of lateral view and liner sleeve, and the utility model jacket type construction line threading fastening devices, 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, the technical solution of the utility model 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 exemplary description is done to the utility model; should be noted that; when not departing from core of the present utility model, 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 domain of the present utility model.
