Abstract
The utility model discloses a metal tube butting and tensioning tool which comprises two buckles, wherein the buckles adopt structures that circular holes are formed in the middles of the buckles, and long straight rod bodies are arranged at the two ends of the buckles; circular rings are arranged at the upper and lower top ends of the buckles; two screws penetrate through the buckles sequentially through the circular rings at the upper and lower top ends of the buckles; and a nut is arranged at each of the two top ends of each screw. With the adoption of the buckle structures that the circular holes are formed in the middles of the buckles, and the long straight rod bodies are arranged at the two ends of the buckles, the circular rings are arranged at the upper and lower top ends of the buckles, the screws penetrate through the buckles sequentially through the circular rings at the upper and lower top ends of the buckles, and each nut is arranged at each of the two top ends of each screw, so that butting of two metal tubes can be accomplished very well.
Description
Technical field
The utility model relates to a kind of metal tube butt joint tensioning tool, relates in particular to a kind of for higher two metal tubes of case hardness or the instrument of metal bar end closed butt joint.
Background technology
In engineering construction, can often use cylindrical metal tube or metal bar, often need long parts are formed in metal tube or metal bar butt joint welding.But because cylindrical metal tube or metal bar surface are slick and sly, lack effective docking calculation, cause the docking point instability, docking location is thrown off easily or is slided in construction, can cause certain threat to construction effect and personal safety like this.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of metal tube butt joint tensioning tool that provides, it can well finish the mating operation of two metal tubes.
The purpose of this utility model is achieved in that
A kind of metal tube butt joint tensioning tool, it comprises fastener, and fastener is for the centre is provided with circular hole, two ends are the structure of long straight-bar body, and fastener is provided with annulus in two tops up and down; Two screw rods by fastener up and down the annulus on two tops pass two fasteners successively; Screw rod two tops are respectively equipped with nut.
A kind of modified of said structure is fastener by two centres is that semicircular ring, two ends are that the body of rod of long straight-bar body structure is interlocked and forms.Even make that like this two metal bars of required butt welding or metal tube size are big slightly, this structure also can well be finished mating operation.
The another kind of modified of said structure is that the front of fastener is strip, and the circular hole in the middle of the fastener is provided with circular hole between two tops and the front that is positioned at fastener.Can make screw rod pass through circular hole like this, and at the screw rod two ends nut is set, two bodies of rod are buckled into very firm fastener, strengthen the stability in the docking operation.
Fastener, the preferred steel body of rod of screw rod.
The utility model has been obtained following technique effect:
At first the utility model has adopted fastener for the centre is provided with circular hole, two ends are the structure of long straight-bar body, fastener is provided with annulus in two tops up and down, two screw rods by fastener up and down the annulus on two tops pass two fasteners successively, screw rod two tops are respectively equipped with the structure of nut, can well finish the mating operation of two metal tubes; Secondly to have adopted fastener be that semicircular ring, two ends are the structure that the body of rod of long straight-bar body structure is interlocked and forms by two centres to the utility model, even can make two metal bars of required butt welding or metal tube size big slightly, this instrument also can well be finished mating operation; In addition to have adopted the front of fastener be strip to the utility model, circular hole in the middle of the fastener is provided with the structure of circular hole between two tops and the front that is positioned at fastener, can make screw rod pass through circular hole like this, and at the screw rod two ends nut is set, two bodies of rod are buckled into very firm fastener, strengthen the stability in the docking operation; Fastener, screw rod are the steel body of rod simultaneously, can effectively strengthen intensity and the durability of this instrument self.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present utility model;
Fig. 2-3 is the structural representation of fastener among Fig. 1;
Fig. 4 is use schematic diagram of the present utility model.
The specific embodiment
A kind of metal tube docks tensioning tool as shown in Figure 1, and it comprises fastener 1, and fastener 1 is for the centre is provided with circular hole, two ends are the structure of long straight-bar body, and fastener is provided with annulus 2 in two tops about in the of 1;
Two screw rods 4 pass two fasteners 1 successively by the annulus 2 on fastener two tops about in the of 1;
4 liang of tops of screw rod are respectively equipped with nut 5.
Shown in Fig. 2-3, fastener 1 is that semicircular ring 6, two ends are that the body of rod of long straight-bar body structure is interlocked and forms by two centres.
As shown in Figure 1, the front of fastener 1 is strip, and the circular hole in the middle of fastener 1 is provided with circular hole 3 between two tops and the front that is positioned at fastener 1.
Fastener 1, screw rod 4 are the steel body of rod 5, can effectively strengthen the intensity of this instrument like this.
When adopting said structure, two metal bars 7 that will need earlier to dock or metal tube pass the circular hole in the middle of the fastener 1, by screw rod 4 and nut 5 fastener 1 is strained gradually toward the centre, fastener 1 drives metal bar 7 or metal tube finally reaches the effect that two metal tubes or metal bar are strained in butt joint again.According to the difference of concrete condition of construction, can regulate the pulling force of stretching screw.This butt joint tensioning tool is simple to operate, easy to use, can effectively solve cylindrical metal tube or metal bar 7 long-time stable butt joints, guarantees construction quality.
