Abstract
The open evolute clamping device for building operations line of the utility model, one end of cylindrical shell is closed and is fixedly installed draw ring in middle position, and other end opening is also fixedly installed central clamping column at central coaxial, at barrel arranged outside second screw thread; The barrel arranged outside closing one end at cylindrical shell screws parts, described in screw parts inner side the first screw thread is set, the first screw thread and the second screw thread match; From cylindrical shell blind end to cartridge openings end, the thickness of barrel increases gradually, and on the barrel of cartridge openings end, evenly arranges gap along barrel circumferencial direction.The technical solution of the utility model adopts clamping mode outside sleeve, in actual use, only needs to screw parts and can realize easily and reliably connecting, improve engineering construction efficiency, facilitate threading.
Description
Technical field
The utility model relates to construction engineering technical field, more specifically, relates to the evolute clamping device for building operations 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.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, is provided for the evolute clamping device of building operations line, is intended to quickly and easily construction line to be compiled bundle, and can convenient connection and running through.
Technical purpose of the present utility model is achieved by following technical proposals:
For the evolute clamping device of building operations line, comprise draw ring, cylindrical shell and screw parts, wherein:
One end of described cylindrical shell is closed and is fixedly installed draw ring in middle position, and the other end opening of described cylindrical shell is also fixedly installed central clamping column at central coaxial, at barrel arranged outside second screw thread; The barrel arranged outside closing one end at cylindrical shell screws parts, described in screw parts inner side the first screw thread is set, described first screw thread and the second screw thread match;
From cylindrical shell blind end to cartridge openings end, described barrel inner surface surrounds the cylindrical lumens of equal diameter, and the thickness of barrel increases gradually, and on the barrel of cartridge openings end, evenly arranges gap along barrel circumferencial direction.
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.
In technique scheme, described in screw parts be hex nut.
Compared with prior art, the technical solution of the utility model adopts clamping mode outside sleeve, utilization screws parts and implements to screw along barrel, space between barrel and central clamping column is reduced gradually, to realize the fixing of line of constructing in sleeve, namely by screwing parts, container wall inwardly shrinks, owing to arranging gap at the barrel of cartridge openings end, 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 parts 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 structural representation of the present utility model (3).
Wherein 1 is draw ring, and 2 is cylindrical shell, and 3 is the first screw thread, and 4 for screwing parts, and 5 is barrel, and 6 is the second screw thread, and 7 is central clamping column, and 8 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, lateral view and elevation, and the utility model externally screwed construction wire harness sleeve, comprises draw ring, cylindrical shell and screw parts, wherein:
One end of described cylindrical shell is closed and is fixedly installed draw ring in middle position, and the other end opening of described cylindrical shell is also fixedly installed central clamping column at central coaxial, at barrel arranged outside second screw thread; The barrel arranged outside closing one end at cylindrical shell screws parts, described in screw parts inner side the first screw thread is set, described first screw thread and the second screw thread match;
From cylindrical shell blind end to cartridge openings end, described barrel inner surface surrounds the cylindrical lumens of equal diameter, and the thickness of barrel increases gradually, and on the barrel of cartridge openings end, evenly arranges gap along barrel circumferencial direction.
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.
In technique scheme, described in screw parts be hex nut.
Compared with prior art, the technical solution of the utility model adopts clamping mode outside sleeve, utilization screws parts and implements to screw along barrel, space between barrel and central clamping column is reduced gradually, to realize the fixing of line of constructing in sleeve, namely by screwing parts, container wall inwardly shrinks, owing to arranging gap at the barrel of cartridge openings end, 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 parts 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.
