Detailed Description
In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings.
As shown in fig. 1 to 3, an embodiment of the present utility model provides a hexagonal flange-meretrix-groove self-extruding screw, which includes a screw head 1 and a screw rod fixedly connected with the screw head 1. The screw head 1 is provided with the operation groove 121 far away from the one end of screw rod, the screw rod include with locking screw thread section 2 of coiled hair 11 fixed connection and fixed connection keep away from the tapping screw thread section 3 of coiled hair 11 one end at locking screw thread section 2, the one end that the tapping screw thread section 3 kept away from locking screw thread section 2 is provided with planar rod end 32. The outer circumferential surface of the locking thread section 2 is provided with a locking thread 21, the tapping thread section 3 is in a truncated cone shape, and the diameter of the tapping thread section 31 is gradually decreased from the locking thread section 2 towards the rod end 32. The outer circumferential surface of the tapping thread section 3 is provided with a tapping thread 31, and the locking thread 21 and the tapping thread 31 are double-thread threads.
When the screw thread tightening device is used, the tapping thread section 3 is screwed into the prefabricated hole of the tightening workpiece and the tightened workpiece, a thread groove is formed in the prefabricated hole, then the locking thread 21 of the locking thread section 2 is meshed with the thread groove of the tightening workpiece and the thread groove of the tightened workpiece so as to realize connection and fixation of the tightening workpiece and the tightened workpiece, because the tapping thread section 3 is in a round table shape, the taper is relatively smaller, when the tapping thread section 3 is screwed into the prefabricated hole, the prefabricated hole is not stretched out instantly, so that the tapping torque can be reduced, the structural strength of the tightening workpiece and the tightened workpiece is not easily damaged, and the tapping thread 31 on the tapping thread section 3 adopts double-line threads so that double-line thread grooves are formed on the inner side walls of the tightening workpiece and the prefabricated hole on the tightened workpiece, and the locking thread 21 on the locking thread section 2 is meshed with the double-line thread grooves when the locking thread section 2 is screwed, and the locking thread 21 is also in double-line thread shape matched with the double-line thread grooves, and the thread design of the double-line thread groove is more compact, so that the locking thread section 2 has better bearing capacity and larger bearing capacity, the tapping thread 31 is not easy to be connected with the tightening screw, the tightening screw is not easy to be corroded, the tightening screw is easy to be corroded, and the tightening screw is easy, and the air is easy to be corroded, and the tightening screw is easy, and has poor stability, and can be easily be connected with the tightening screw and the air is easy.
The mode has the advantages of small attack torque, difficult damage to the workpiece, large locking torque and high workpiece connection stability.
In this embodiment, the locking thread 21 and the tapping thread 31 are triangular.
In the above-mentioned setting, triangle-shaped's tooth form has better structural stability to the condition of sliding tooth is difficult to appear when using.
In this embodiment, the thread form angles of the locking thread 21 and the tapping thread 31 are each 55 °.
In the above arrangement, it was found that the 55 ° thread form has a better locking torque than the conventional 60 ° thread form during actual use.
