Description

The plug into device that screws of usefulness of reinforcing bar

The utility model relates to the plug into device that screws of usefulness of a kind of reinforcing bar.

Generally taking place because of there is reinforcing bar to break to fall the facts of continued access in the relation regular meeting of number of floor levels when construction, therefore is that the reinforcing bar 9 that must will be extended and extend usefulness with as shown in Figure 6 hollow form adapter sleeve 95 is docked the spiral shell group; Yet, it is to hold reinforcing bar and rotated, screw tight in artificial mode that traditional reinforcing bar extends, strengthened it with large-scale spanner again and screwed tight intensity, cause trouble, inconvenience, screw tight strength deficiency and screw tight the shortcoming that work can't be carried out smoothly, more and must many people screw tight operation simultaneously, time-consuming, effort and efficient are extremely low.

The utility model main purpose is that a kind of the device that screws of usefulness " reinforcing bar plug into " is being provided, make and need not directly to rotate to hold reinforcing bar, or instrument such as mat spanner and rotate this as the reinforcing bar that extends usefulness very difficultly, but with machine carry out very easily and easily reinforcing bar screw tight work, more can a people during construction independently finish screwing tight operation.

Secondary objective of the present utility model is also providing a kind of the device that screws of usefulness " reinforcing bar plug into ", by this appropriate location that screws device is to have a backstay that a side is stretched, and only has the post that spins to rotate and positioning function that left and right folder can and then not rotate but use to reach screwing being held in a certain fixture of this backstay of mat when extending with reinforcing bar.

The purpose of this utility model is achieved in that

The plug into device that screws of usefulness of a kind of reinforcing bar is to comprise: left and right folder, that can left and right involutory clamping spin post, a drive division, a rotating shaft and a buckling parts, wherein:

Axle center after this left and right folder is involutory is to form the hollow form of suitable size and be nested with a post that spins that can axially rotate; Left side folder outer edge side have one be horizontally set with and in have the drive division of screw rod, the drive axle that its screw rod and mat one expose and be subjected to driven rotary;

The involutory surface two ends of this left and right folder are to be provided with respectively to provide left and right folder opening and closing with reaching the fixedly rotating shaft and the buckling parts of usefulness;

This also forms the left and right post that spins that revolves portion of double shape of semicircle, and its internal ring wall is the tool screw thread relative with screw thread steel, its external annulus then can with above-mentioned drive division screw rod bridle joint;

Make by driven tool and make drive division screw rod and the post that spins rotation to see through the drive axle, this reinforcing bar that is gripped in post that spins then is driven to rotate, with will be extended with the reinforcing bar that extends usefulness by a hollow form and interior helicoid adapter sleeve and convenient and securely plug into.

The utility model is further to set up a hollow barrel mast at the left and right folder and the intercolumniation that spins, this hollow barrel mast also forms the left and right of double shape of semicircle and is fixedly arranged in aforementioned left and right folder inwall respectively by wall, and should be by wall and folder adjacent according to a left side or right by wall the semicircle outer wall and form a conduit, this conduit also on a left side or right corresponding wall place formation bore by wall less than the perforation shape of conduit; A left side communicates by the conduit of wall and with the inside of drive division; The left and right external annulus that revolves portion of post of spinning then protrudes out the double wedge with respect to aforementioned conduit, revolve portion's loose joint in left and right inwall with left and right respectively with the embedding group of mat double wedge and conduit by wall, and the double wedge of left-handed portion and see through a left side by wall and with drive division screw rod bridle joint, make the axis of a cylinder that spins to rotation driven by screw rod.

The screw rod of described drive division, its axle center just are parallel to the involutory surface of the left or right folder that is depended on.

Described rotating shaft is made up of three stacked axle sleeves and an axostylus axostyle; Upper and lower axle sleeve is to be connected with a left side or right folder, and middle axle sleeve then is connected with the right side or left folder, and three axle sleeve centers are mat axostylus axostyle and bolt then.

Described buckling parts is to comprise the rotating shaft that is arranged at a left side or right folder and be arranged at the right side or the flange of left folder constitutes; This rotating shaft is made up of three stacked axle sleeves and an axostylus axostyle, upper and lower axle sleeve is to link to each other with corresponding folder, and middle axle sleeve connect then that a side stretches can the mat rotating shaft and dial the fastening bar that changes, the center of three axle sleeves and mat axostylus axostyle bolt, the relative part of another folder then protrude out two flanges that keep a distance each other; Above-mentioned fastening bar be able to stretch into two flanges and ask after dial changeing, make this outer end of mat form shape of threads and utilize that to adjust nut in addition fastening to reach the purpose that is fastened.

Described drive division outer wall is to be convexly equipped with two lugs relatively, bolt a positioning rod between two lugs, but only there is the post that spins to rotate and positioning function that left and right folder can and then not rotate in order to reach screwing being held in a certain fixture of this backstay of mat when extending with reinforcing bar.

The left-handed portion of the described post that spins, the both sides of its involutory surface are relative projection of tool or shrinkage pool, the both sides of dextrorotation portion involutory surface then have relative shrinkage pool or projection, revolve portion projection can relative clamping with shrinkage pool and reach the effect of location when spinning post to synthetic for left and right.

The utility model by the cavity after left and right folder is involutory set also be double shape of semicircle and the rotatable post that spins, for the set drive division of the suitable side of a folder wherein and driven rotary, the hollow inside of this post that spins is the screw thread that has with respect to reinforcing bar, to utilize driven tool to drive the drive division rotation and then make clamping that the post rotation that spins of reinforcing bar be arranged from outside, to extend an end that is tightened in adapter sleeve with reinforcing bar very easily and reach, it screws tight strength enhancing, when operation is very laborsaving and the work of screwing tight is successfully carried out.

The backstay of stretching by this side that appropriate location was provided with that screws device in addition only has the post that spins to rotate and positioning function that left and right folder can and then not rotate but use to reach screwing being held in a certain fixture of this backstay of mat when extending with reinforcing bar.
