Abstract
The utility model discloses an electric PVC (Poly Vinyl Chloride) fire-retardant pipe bending device composed of a compression bar, a sleeve, a connecting nut and a connecting screw. The sleeve refers to a steel pipe matched with the PVC fire-retardant pipe in pipe diameter; the specification of the steel pipe is phi 16 mm, phi 20 mm, phi 25 mm, or phi 32 mm, and length: 30 mm; the two ends of the steel pipe are polished smoothly by a polishing machine; and the phi 10 mm connecting nut is firmly welded at one side of the sleeve and connected to the connecting screw. The compression bar is formed by welding the phi 10 mm connecting screw with a phi 14 mm deformed steel bar which is 300-500 mm long; a 45-degree groove is formed at one side of the phi 14 mm deformed steel bar which is 300-500 mm long; and the phi 10 mm connecting screw is firmly welded with the phi 14 mm deformed steel bar which is 300-500 mm long by an angle of 45 degrees. Besides, the compression bar is screwed down with the sleeve of the corresponding specification, so that the electric PVC fire-retardant pipe bending device is assembled. The electric PVC fire-retardant pipe bending device is simple to fabricate, labor-saving and time-saving, and capable of greatly improving once pipe bending success rate and reducing material losses; therefore, the construction quality of guaranteed and potential safety hazards are eliminated simultaneously.
Description
Technical field
The utility model belongs to technical field of building construction, is electric PVC electrician's Frpipe swan neck system specifically, is applied to the bend pipe operation when electric PVC electrician's Frpipe is pre-buried in the construction.
Background technology
In the building of a house construction engineering job site interior electrical construction process, it is shorter that the pre-buried federation of PVC electrician's Frpipe runs into bending section, the situation that the bend pipe difficulty is big.Existing PVC electrician's Frpipe bending method is that the workmen is with the rigid bend pipe of rough power.Because the intensity of PVC electrician's Frpipe own is less, in the bend pipe process, pvc pipe is fractureed easily, causes the loss of material, uses rough power bend pipe simultaneously, the workmen overexerts because of crank, causes losing center of gravity easily and falls down, and has potential safety hazard.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned shortcoming that exists to prior art, and electric PVC electrician's Frpipe swan neck system is provided, and not only make simply, but also potential safety hazard has been eliminated in the saving of work and time material saving.
The purpose of the utility model realizes like this: electric PVC electrician's Frpipe swan neck system is made up of depression bar, sleeve pipe, coupling nut, connecting screw rod.The steel pipe that sleeve pipe is complementary for the PVC Frpipe caliber with the need bending; Generally selecting specification for use is the steel pipe of Ф 16mm, Ф 20mm, Ф 25mm, Ф 32mm; Length 30mm; The steel pipe two ends polish smooth with sanding machine, again Ф 10mm coupling nut firmly are welded on sleeve pipe one side, in order to be connected with connecting screw rod.Depression bar is welded by Ф 10mm connecting screw rod and the long Ф 14mm screw-thread steel of 300 ~ 500mm; Make a call to one 45 degree grooves in long Ф 14mm screw-thread steel one side of 300 ~ 500mm, become miter angle firmly to weld with the long Ф 14mm screw-thread steel of 300 ~ 500mm Ф 10mm connecting screw rod.The sleeve pipe of depression bar and corresponding specification tightened promptly form electric PVC electrician's Frpipe swan neck system.
During use, crooked as required PVC electrician's Frpipe caliber is chosen the sleeve pipe of corresponding specification, tightens assembling through coupling nut, connecting screw rod and depression bar.Then electric PVC electrician's Frpipe swan neck system being enclosed within needs on crooked PVC electrician's Frpipe, and in PVC electrician's Frpipe, puts into the spring tube bending device, and the downward moulded rod of evenly exerting oneself utilizes lever principle can accomplish the bend pipe operation.Only need covering device recycling can accomplish the pre-buried bend pipe of electric PVC electrician's Frpipe during site operation.
Compared with prior art, the advantage of the electric PVC electrician's Frpipe of the utility model swan neck system is: make simply, both saving of work and time improved the bend pipe success rate again greatly one time, had reduced the loss of material, had guaranteed construction quality, had eliminated potential safety hazard simultaneously.
Description of drawings

Fig. 2: electric PVC electrician's Frpipe swan neck system vertical view.
Among the figure: 1, depression bar 2, sleeve pipe 3, coupling nut 4, connecting screw rod.
The specific embodiment
For further describing the utility model, the electric PVC electrician's Frpipe of the utility model swan neck system is further described below in conjunction with accompanying drawing.
As shown in the figure, the electric PVC electrician's Frpipe of the utility model swan neck system is made up of depression bar (1), sleeve pipe (2), coupling nut (3), connecting screw rod (4).Crooked as required earlier PVC Frpipe caliber is selected the steel pipe of Ф 16mm, Ф 20mm, Ф 25mm, Ф 32mm for use; Every section 30mm is long; The steel pipe two ends polish smooth with sanding machine and are made into all size sleeve pipe (2); Ф 10mm coupling nut (3) firmly is welded on sleeve pipe (2) one sides, in order to be connected with connecting screw rod.Depression bar (1) is welded by Ф 10mm connecting screw rod (4) and the long Ф 14mm screw-thread steel of 300 ~ 500mm; Make a call to one 45 degree grooves in long Ф 14mm screw-thread steel one side of 300 ~ 500mm, become miter angle firmly to weld with the long Ф 14mm screw-thread steel of 300 ~ 500mm Ф 10mm connecting screw rod (4).The sleeve pipe (2) of depression bar (1) and corresponding specification tightened promptly form electric PVC electrician's Frpipe swan neck system.
During use, crooked as required PVC electrician's Frpipe caliber is chosen the sleeve pipe (2) of corresponding specification, tightens assembling through coupling nut (3), connecting screw rod (4) with depression bar (1).Then electric PVC electrician's Frpipe swan neck system being enclosed within needs on crooked PVC electrician's Frpipe, and in PVC electrician's Frpipe, puts into the spring tube bending device, and the downward moulded rod of evenly exerting oneself utilizes lever principle can accomplish the bend pipe operation.Only need covering device recycling can accomplish the pre-buried bend pipe of electric PVC electrician's Frpipe during site operation.
