As shown in fig. 1-3, a novel mechanical connection device without turning threads comprises a left nut 1, a left external thread connection pipe 2 with a notch, a screw 4, a sleeve 6, a right external thread connection pipe 7 with a notch, and a right nut 8; an internal thread hole is arranged in the left nut 1, an internal thread hole is arranged in the right nut 8, a left external thread connecting pipe 2 with a notch is fixed at the left end of the sleeve 6 (which can be of an integrated structure, the inner hole of the left external thread connecting pipe 2 with the notch is communicated with the inner hole of the sleeve 6), a right external thread connecting pipe 7 with a notch is fixed at the right end of the sleeve 6 (which can be of an integrated structure, the inner hole of the right external thread connecting pipe 7 with the notch is communicated with the inner hole of the sleeve 6), an external thread for being in threaded connection with the left nut 1 is arranged on the left external thread connecting pipe 2 with the notch, a plurality of notches 3 (2-12, preferably 4 uniform distributions, namely the size of the inner hole of the left external thread connecting pipe 2 with the notch can be finely adjusted, the opening is conveniently adjusted to be enlarged to be placed into a reinforcing steel bar), an external thread for being in threaded connection with the right nut 8 is arranged on the right external thread connecting pipe 7 with the notch, a plurality of notches 3 are formed in the external thread connecting pipe 7 with the right notch (the number of the notches is 2-12, and the best number is 4, and the notches are uniformly distributed, namely the size of an inner hole of the external thread connecting pipe 7 with the right notch can be finely adjusted, so that a reinforcing steel bar can be conveniently placed in the opening by enlarging the size of the inner hole; the left nut 1 is in threaded connection with the left external thread connecting pipe 2 with the notch, and the right nut 8 is in threaded connection with the right external thread connecting pipe 7 with the notch;
the left part of the left nut 1 is a cone with a small left end and a large right end, and the left part of the internal threaded hole of the left nut 1 is a cone hole with a small left end and a large right end (the inner diameter of the part without the screw at the left end is gradually reduced); the left end part of the left nut 1 has no wire and the hole at the position without the wire is gradually narrowed, so that when the screw thread is screwed, the reinforcing steel bar is engaged more and more tightly;
the right part of the right nut 8 is a cone with a large left end and a small right end, and the right part of the internal threaded hole of the right nut 8 is a cone hole with a large left end and a small right end (the inner diameter of the part without the screw at the right end is gradually reduced); the right end of the right nut 8 is threadless and the hole narrows slowly so that when the screw is tightened, the reinforcement is engaged more and more tightly.
The left part and the right part of the sleeve 6 are respectively provided with a plurality of internal thread holes 5 (the plurality is 2-6) along the circumference, the internal thread holes 5 are communicated with the inner hole of the sleeve 6, and the screws 4 are screwed into the internal thread holes 5.
The right part of the left nut 1 is carved with anti-skidding threads, so that the nut can be conveniently screwed by a torque wrench. The left nut 1 is tightened as the inner diameter is smaller and larger (the inner diameter is gradually smaller at the left end portion where no wire is present).
The left part of the right nut 8 is carved with anti-skidding screw threads, so that the torque wrench can conveniently screw the nut.
The working principle is as follows:
as shown in fig. 1-3, use is made of: and screwing down the left nut 1 and the right nut 8. The right end part of the left reinforcing steel bar 9 penetrates through the left nut 1 and the left external thread connecting pipe 2 with the notch and then is inserted into the left part of the sleeve 6; screwing a left nut 1 on the left external thread connecting pipe 2 with the notch and screwing; the screw 4 on the left part of the sleeve 6 is screwed (when the reinforcing steel bar is put into the sleeve, the screw can be screwed to fix the reinforcing steel bar), and the right end part of the left reinforcing steel bar 9 is fixed on the device. The left end part of the right reinforcing steel bar 10 penetrates through a right nut 8 and a right external thread connecting pipe 7 with a notch and then is inserted into the right part of the sleeve 6; screwing a right nut 8 on the right external thread connecting pipe 7 with the notch and screwing; the screw 4 on the right part of the sleeve 6 is screwed (when the steel bar is put into the sleeve, the screw can be screwed to fix the steel bar), and the right end part of the right steel bar 10 is fixed on the device. This connects the left reinforcement bar 9 and the right reinforcement bar 10 together.
The external screw thread connecting pipe 2 of left side tape slot mouth, the external screw thread connecting pipe 7 of right side tape slot mouth can finely tune big entry and put into the reinforcing bar, and the left end portion of left nut 1, the right-hand member portion of right nut 8 do not have silk and do not have silk department entrance to a cave slowly narrow down to when the screw thread is screwed up, the reinforcing bar can be by the more and more tight of interlock, fix the reinforcing bar with this. Meanwhile, a plurality of internal thread holes (or called screw holes, the specific number is determined according to the thickness and the strength of the steel bar) are arranged on the sleeve close to the entrance of the steel bar, when the stress requirement is not high, the screw or the nut can be fixed alternatively, and after the steel bar is placed in and the nut is screwed, the screw (small screw) is screwed, so that the steel bar is fixed in multiple ways. The fixing method is simple for workers to operate, and the structure is easy to process and obtain and convenient for mass production. In order to guarantee the stress requirement of the middle round sleeve in the using process, the sleeve is preferably replaced by a high-strength material, and meanwhile, when the reinforcing steel bars are arranged, two ends of the reinforcing steel bars need to be tightly attached to each other, and the lengths of the reinforcing steel bars at the two ends are equal.
