Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and the detailed description.
In the first embodiment, as shown in fig. 1, an adjusting bolt includes two screws 1 and a connecting member 2, one end of each screw 1 is provided with a connecting portion 11 for connecting a cable, the other end of each screw is provided with an external thread section 12, two ends of each connecting member 2 are provided with through holes 24 for the screws 1 to pass through, cavities 21 for the screws 1 to screw in are formed in the inner sides of the through holes 24, internal threads matched with external threads of the screws are formed in the through holes 24, the connecting member 2 is connected with the two screws 1 in a thread fit manner, first fixing holes 23 which are fixed in size and independent relative to the cavities 21 are formed in the connecting member 2, and the penetrating direction of the first fixing holes 23 is perpendicular to the central axial direction of the through holes 24. This embodiment is at the job site, can be through the first fixed orifices 23 on the connecting piece 2 with connecting piece 2 fixed or utilize its swivel connected coupler 2, during the use, can adopt the current material of job site to insert first fixed orifices like the reinforcing bar, perhaps also can support during dedicated fixing tool inserts first fixed orifices 23, then screw up through the screw thread between screw rod 1 and the connecting piece 2, in screwing up the in-process like this, connecting piece 2 can not take place to rotate, it is spacing through fixation nut 3 at last, high durability and convenient installation, and is more laborsaving, and the construction efficiency is improved.
In a further embodiment, a protruding bump 22 is disposed on a side of the connecting member 2, and the first fixing hole 23 is disposed on the bump 22. The two lugs 22 are respectively arranged on the two side edges of the connecting piece 2. In this embodiment, the bumps 22 are disposed symmetrically with respect to the central axis of the through hole 24 and are located on the central line of the connecting member 2. By this arrangement, the fixing force applied to the connecting member 2 during fixing is uniform and more stable.
In a further embodiment, the threaded section 12 of the screw 1 is provided with a fixing nut 3.
In a further embodiment, the connecting portion 11 of the screw rod 1 is of a circular ring structure.
In a further embodiment, a window for observing the screwing position of the screw is formed in the connecting piece 2 corresponding to the position of the cavity 21.
Second embodiment as shown in fig. 2, the structure of the present embodiment is similar to that of the first embodiment, except that the protrusion 22 is disposed on one side of the connecting member 2, so as to fix the connecting member 2 when the screw 1 is rotated, but compared with the first embodiment, the single-side fixation is adopted, the whole force applied to the connecting member 2 is single-sided, relatively uneven, and easy to twist left and right.
Third embodiment as shown in fig. 3, the structure of the present embodiment is similar to that of the first embodiment, except that the protruding blocks 22 are arranged on both sides of the connecting member 2, but the positions of the protruding blocks 22 on both sides are respectively shifted from the center line of the connecting member 2 to the left and right, so that the connecting member 2 can be fixed while rotating the screw 1, but compared with the embodiment, the two first fixing holes 23 are farther apart, and the two first fixing holes 23 are fixed by reinforcing steel bars, which is inconvenient to operate, and can be fixed by a special fixing tool.
Fourth embodiment as shown in fig. 4, the structure of the present embodiment is similar to that of the first embodiment, except that the first fixing hole 23 of the present embodiment is disposed at a position between two screws 1, the connecting member 2 is provided with two cavities 21 into which the screws 1 are screwed, the first fixing hole 23 is disposed between the two cavities 21, and a stopper 25 is disposed between the first fixing hole 23 and the cavities 21.
